    ROTATING DRUM AND METAL RECOVERY. A rotary drum metal retriever includes an inner cylinder and a concentric outer cylinder, which rotate simultaneously. The inner cylinder includes a first compartment, which receives material to break through the teeth, a second compartment that receives the broken material from the first compartment and crushes the material into smaller particles, and a third compartment, in which the particulate material enters the space between the inner cylinder and outer cylinder, by friction, by the perforated screens. The second compartment includes a crusher, having various items for crushing block material as it rotates. The third compartment also provides breakage and transport of the particulate material. The particulate material then returns approaching the inlet for separation into coarse and fine sizes, and later collection for reuse. Metals and metallic oxides exit the drum through the openings in the rear of the third collection compartment. The drum recovers metals, metal oxides, sand and other materials for reuse.

    RECIPROCAL REMISSION ON RELATED PATENT APPLICATION
    [0001] This international patent application / PCT claims priority to the non-provisional patent application for patent having serial no. 12/460,524, filed on July 21, 2009. BACKGROUND OF THE INVENTION
    [0002] This invention relates to shaking units, used to separate or remove metal from molten objects, slag and sludge, in a foundry, a mill, or other works, and, in particular, to a rotating drum having blade propellers spaced and serrated blades in the friction chamber.
    [0003] In forming a drum mill, such as a casting shaking unit, a rotary separator, a media drum, a material dryer, a block crusher reclaimer, a mixing drum, a sand screen , or the like, the mill generally has three chambers: an inlet chamber, a crushing chamber and a friction chamber. The inlet chamber, or first compartment, receives the raw molten objects and conglomerates from a foundry or other process. Raw cast objects and the like enter the admission by eviction or direct discharge from a preceding process. Into the machine's interior of the inlet chamber, a crushing chamber, or second compartment, receives the molten objects and the partially broken conglomerates at the inlet.
    [0004] The second compartment has a crushing means, which rotates independently of the machine and rolls on the inner surface of the machine. Molten objects and partially broken conglomerates pass side by side and then under the crushing medium for further reduction and separation.
    [0005] Behind the crushing chamber and generally opposite the inlet chamber, a friction chamber, or third component, separates the molten metallic objects from sand and other particles. The friction chamber collects sand and other particles from inside the machine and returns them towards the intake chamber, in a passage between the outer cylinder and the inner cylinder. The friction chamber has inside it serrated, serrated elevators, spaced apart, on locking plates with holes. The elevators, at a high turning speed, easily separate the sludge, slag and salt cake, to release and clean metals and metallic oxides. Vertical vanes within the friction chamber guide the metals and metallic oxides towards an outlet, opposite the inlet chamber, while sweeping the sludge and sand through the friction chamber so that they fall into the holes and then into the passage for removal.
    [0006] There are several machines and apparatus on the market and in use, which are applied for reducing block material to a usable consistency. For example, clumps of sand, which are usually chemically bonded together, after being broken off from the mold or casting used in the foundry industry, can be reduced to a granular texture for immediate reuse in forming a mold for later casting.
    [0007] A unique aspect of the present invention is blades helically arranged in the friction chamber, which both break the clods, and advance the resulting broken materials in the rotating drum, for further classification and separation. The blades are spaced apart from each other, and each of them has grooves longitudinally along its inner edge. The rotating drum also has a crusher, which occupies the volume of the crushing chamber and has teeth spaced apart on the leading edge of the crusher. After the crusher, the helical vanes pass material through the friction chamber and along the spaced apart blades , which further separate the metals from clods of sand and sludge. These blades are spaced apart and have a serrated inner edge. SUMMARY OF THE INVENTION
    [0008] A turning unit, such as a shaking unit, a drum of rotating media, a sand retriever or the like, includes a cylindrical outer shell and a concentric cylindrical inner shell. The inner cylinder has a liner, formed from a series of interlocking segments. The revolving unit or rotating media drum reduces block material into particulate material, suitable for reuse and recycling in industrial processes. The drum includes an inner cylinder, and a concentric outer cylinder, which, at one end, extends beyond the inner cylinder to form a larger diameter inlet compartment for receiving the block material. A laser-aligned base incorporates a drive means, which supports and drives the drum, which is disposed substantially horizontally, in rotation.
    [0009] An inlet chamber, or first compartment, receives the material in block, and has a diameter equal to or greater than the rest of the outer cylinder. The inlet chamber also contains high profile teeth, helically arranged, which advance the block material through the first compartment towards a crush chamber in the inner cylinder. The first compartment of the inner cylinder contains means for breaking the block material into smaller pieces, and for separating sand and other recovered aggregates. The preferred means of breaking the block material into smaller pieces is a combination of paddles. The first compartment also preferably contains, in a first segment, teeth or vanes for advancing the block material, obtained from the inlet compartment, to the crushing means of the second compartment. The crushing medium advances the smaller pieces, obtained in the first compartment, to a friction chamber.
    [0010] The friction chamber has at least one partially perforated cylindrical wall, in which a high turning action further reduces the size of the pieces to particulate material, so that at least a part of the material passes through the perforations. Any material that does not pass through the perforations leaves the friction chamber through a metal outlet. In addition, a conveyor vane is provided in the intermediate part between the inner and outer cylinders, to longitudinally move any particulate material deposited thereon to a set of screens near the inlet, for an even finer classification of the particles. Any material remaining on the screen is recycled to the inlet compartment, to be redeposited in the machine for further crushing. The apparatus of the present invention is suitable for reducing the size of block material, both sand and metals, to particulate material of a predetermined size.
    [0011] The present invention uses a rotary block crusher/sand recovery drum for the recovery of block/aggregate/granular materials. As shown in the prior art, a rotating media drum recovers sand and metal cores from metallic molten objects. However, the present invention extends to the use of the rotating media drum for processing various block sand materials, including aggregates, chemically bonded sand clods, sludge, ferrous and non-ferrous scrap, and slag. Conventionally, material entering a rotating media drum is fed into one end of the drum by use of a conveyor, paddles, a hopper, a vibrating conveyor, or any means desired to place a large amount of material at the inlet of the drum. rotating sand block processing. Previously, block material, when entering a drum in large quantities, tended to form clumps, which resulted in waves when the material reached the second compartment, in the inner cylinder, which contained the means for crushing the outer cylinder, in addition to the inner cylinder, to form a larger diameter inlet compartment, the material to be passed through it can be placed in the inlet compartment in batches, for distribution in a way to prevent the formation of waves of block material from cumulatively reaching the first compartment. The inlet compartment has high profile segmented helical teeth to advance block material from the inlet into the first compartment. The high profile segmented helical teeth allow the aggregates of block material to separate sufficiently to provide a more uniform material flow to the first compartment. The first compartment also includes screens, external to the inner cylinder, to separate the sand and metal oxides into fine and coarse grades, which are then collected in separate deposits.
    [0012] The first compartment of the inner cylinder breaks and separates the block material into small pieces. Block material breaks into smaller pieces by means of teeth, spades, spikes or the like, which protrude into the inner part of the inner cylinder. As the material hits these paddles or spikes, the clods are reduced in size and provide chunks of material suitable for further treatment and size reduction to a particulate type material. From inside the first compartment, a disk, having certain items, guides the broken material to the second compartment. The disc sweeps the diameter of the inner cylinder. The disc has an internal opening with a plurality of teeth pointing inwards. The internal opening has a diameter in addition to the suspension means for the second compartment, as described below. At the perimeter, the disk has arcuate slits spaced apart by a number of at least three. Each slit has a width, and the spacers between the slits are a length similar to the slit width. In addition to the disk, the disturbed material enters the second compartment of the invention.
    [0013] Within the second compartment, another means, suitable for breaking the clods, is a crusher located inside the apparatus. In a preferred embodiment, a heavy crusher is arranged for rotation within the second compartment, via its pivotal mounting to a flexible suspension means. The suspension means retains the crusher at one end, and the crusher, which is disposed generally longitudinally within the apparatus, is revolved within the apparatus by means of its bearing support. The clods, gradually fed and transferred to this compartment, are substantially broken by pressure, weight and shock, when forced under the crusher, to subject the material to the enormous weight of the crusher. This device is usually metallic and formed to transform any clumps to a significantly reduced size.
    [0014] The crusher, rotatably mounted flexibly by chain supports, extending in equally spaced directions, rotates by gravity with respect to its means of suspension, by means of the rotation of the inner cylinder, which is subjected to rotation by means of an external drive means such as a motor. The flexibility and support of the crusher by chain suspension, to promote play in the crusher's route, so that clumps of material, and any other foreign material, accumulated inside the drum can be gradually moved to the vicinity of the crusher and forced under that segment of the crusher, which is disposed longitudinally close to and aligned with the contiguous surface of the inner cylinder. In this invention, the crusher has several teeth on its head slightly offset from the chain suspension. The teeth extend from a conical-shaped head of the crusher to a rounded base. Alternatively, the teeth have a helical arrangement to propel material around and backward along the crusher. Outward from the base and opposite the head, the crusher has a frusto-conical back. The posterior part has several longitudinal slits and intermediate ribs spaced apart. The ribs and slits cooperate to push the crushed material back from the crusher into the friction chamber. In this invention, the base of the crusher has a diameter approximately equal to that of the inner cylinder.
    [0015] The materials reduced to smaller pieces leave after the second compartment, in the inner cylinder, and are transported to a friction chamber, immediately adjacent to and coaxial with the, second compartment of the inner cylinder. The friction chamber, having at least one partially perforated cylindrical wall, provides a high tipping action to further reduce the size of the remaining block pieces so as to allow a portion of the granular material to pass through the perforations, to further reduce and transfer the particulate material parts for separate collection. The friction chamber may have blades or teeth to reduce the pieces of material to particulate matter, a substantial part of which passing through the perforations of the inner cylinder of the friction chamber. The friction compartment, or third, includes a large vane on a continuous helix, which guides the reduced materials back through the friction chamber. The large reed passes between the spaced teeth. Alternatively, teeth in the friction chamber have multiple serrations on their inner edges.
    [0016] The particulate material, which passes through the perforations of the friction chamber, passes into the space between the inner cylinder and the outer cylinder. The space between the inner cylinder and the outer cylinder is provided with a transport vane, which moves the particulate material longitudinally in the desired direction, depending on the orientation direction of said vanes. In this case, the conveyor vane allows the material to move towards the inlet compartment, in the opposite direction to the flow of material undergoing crushing, inside the inner cylinder. In the illustrated embodiment of the present invention, the reduced particulate material moves towards at least two screens, in which the material is classified, the smaller material falling for collection in at least two warehouses, ducts, or conveyors, while the larger material it drops to pass through the screen, also known as screen-retained materials, and is returned to the inlet compartment. Classification screens can consist of a sheet metal with perforations, or several sheets or screens of varying sizes, or more mesh screens, in order to separate and reclassify the particulate material into more than one size.
    [0017] The material, generally metallic, which does not pass through the perforations in the friction chamber, goes to additional revolving and crushing by the blades, continues through the friction chamber through an outlet provided for metals. The rotary clod crusher/recoverer of the present invention is disposed substantially horizontally to allow rotation. A base means supports the drum and provides a drive means to drive the drum in the desired rotation.
    [0018] Therefore, it is an object of the invention to provide an improved rotating drum / metal retriever.
    [0019] It is another object of the present invention to prevent the accumulation of metals, sand, sludge, saline cake, by-products and other molten waste in the meeting of two blades, and therefore a shock point preventing the flow of materials from the drum .

    [0041] The same reference numbers refer to the same parts throughout the various figures. DESCRIPTION OF THE PREFERRED EMBODIMENT
    [0042] The present technique overcomes the limitations of the prior art by providing additional clod crushing devices. The detailed description presented below illustrates the invention by way of example and not by way of limitation. This description will clearly enable a person skilled in the art to produce and use the invention, and describe the embodiments, adaptations, variations, alternatives and uses of the invention, including what is currently believed to be the best mode for driving the retriever of rotating drum metals 1, shown generally in Figure 1.
    [0043] The rotating drum 1 is preferably a drum constructed and operated as a mill, as previously described in patent no. 3,998,262, to remove sand from molten objects by turning them over. With reference to Figures 1 and 2, the rotary drum reclaimer 1 is provided with an outer cylinder 2 and an inner cylinder 3. The inner cylinder has a smaller diameter than that of the outer cylinder, and the two cylinders define a space between them. to transport particulate matter as described below. The outer cylinder is provided with an inlet compartment 14, in which the block material, to be processed, is placed in the rotating material crushing drum 1. The inlet compartment 14 contains helical teeth 20, which are of a sufficiently profile. high, to allow large clumps and clumps of material to be initially separated into smaller clumps of material, which are relatively evenly distributed on the inner surface of the inlet compartment 14. The inlet compartment 14, which received the material through the inlet area 19, this comprising an opening at the end of the rotating drum 1, transports the material by the helical teeth 20 to the first compartment 15, in which the material is further handled by helical vanes or shuttles 13. The first compartment 15 and the adjacent second compartment 16 contain the feed section, with helical blades 13, and a crushing and grinding medium 23 described below, respectively. The second compartment starts with a suspension means 29 and with a disc 29a, shown below in Figure 2. The disc occupies the inner cylinder and has a central opening constructed by inwardly pointing teeth 29b. The central opening admits block material after the teeth and into the crushing medium. Outside teeth 29b, the disc has a number of partially annular slots 29b. The slits are adjacent to the inner cylinder, and allow block material below the height of the slit to pass into the crushing medium. The disk separates adjacent slits by use of struts 29d, generally having a width proportional to the height of a slit.
    [0044] The crushing and grinding means 23, incorporating the spaced teeth 23a, are anchored in the compartment 16 by a suspension means 29, behind the disc, having chains attached to the inner wall of the compartment. The crushing means 23 is substantially cylindrical in shape, although formed as a tapered cylinder having longitudinal ribs 26, which extend along the length of the crusher segments 24. As shown below in Figure 2, the crusher has a head, generally in connection with the suspension means and having a frustoconical shape, and an opposite posterior part, including the ribs, having an elongated conical shape. The head has a plurality of spaced teeth 23a, arranged parallel to the direction of material flow, and, alternatively, the teeth have a partially helical arrangement. The rear part of the cylinder also has a plurality of slots 26a, generally adjacent to the alternating ribs. The crushing means 23 is generally a heavy metal drum-shaped entity, mounted on a suspension means 29, which functions as a bearing, and which allows the crushing means 23 to rotate by gravity, due to the rotation of the cylinders. The crusher generally occupies almost the entire inner diameter of the inner cylinder. As rotation occurs, the block material passes along the second compartment, thereby collecting the block material below the crusher, so as to squeeze, crush and substantially reduce in size the block material due to the shape. , weight and longitudinal length of the crushing means 23.
    [0045] The crushed material, reduced in size, is passed to the third or friction chamber 17. The friction chamber 17 contains openings 36 in the inner cylinder wall, which allow material small enough in size to be sorted to pass through the openings. 36. In addition, the friction chamber 17 contains paddles 33, which help to further reduce the size of crushed material received in the friction chamber 17 of crushing means 23. The paddles lift and drop the granular block material. At least one helical vane 17a guides and drives the granular block material backwards by the action of the friction chamber. Any metallic material, which is not reduced to a sufficient size to pass through the openings 36, exits through a metal opening, as at 22, for one or more later uses. Drum 1 further includes an inspection port, as at 28, opposite the inlet for use during drum operations and maintenance.
    [0046] The particulate material, which passes through the openings 36, is deposited in the space between the outer cylinder 2 and the inner cylinder 3. Inside the space is a continuous conveyor means, in the form of helical vanes 37, which sweep the material in the direction of the inlet compartment 14, in the opposite direction from the material undergoing crushing, into the inner cylinder. Material exits through an exit hole 32 in a first thin screen 35. The screen forms the outside of the inlet compartment. Helical vanes 18 are located between the thin screen 35, a second or coarse screen 35a, and the surface of the inlet compartment 14. The helical vanes 18 sweep the surface of the screens 35, 35a to direct the particulate material forward over the screens for fine and coarse metal oxides, to collect them, and then the very large material, to pass through the screen, goes towards the material collection hole 34. Thus, the extra large coarse material, or material retained in the screen, is recycled through outlet port 34 to inlet compartment 14 for a second crushing and milling attempt. The material passing through the screens 35, 35a is deposited in the particulate material collector 30, with sub-collectors for fine materials 30a and coarse materials 30b. A dust collector 21 is located above the inlet compartment 14. The dust collector does not rotate, as part of the drum of rotating means, nor does the collector 30 and the particulate material sub-collectors 30a, 30b.
    [0047] The outer cylinder 2 incorporates on its outer surface a pair of guides, tracks or tracks spaced apart, as in 4 and 5, which are positioned to run or slide in roller bearings, as can be seen in 6 and 7, the bearings being provided on each side of the apparatus and formed in the base means 8. The base means 8 supports the cylinder 2 and the entire apparatus 1 for rotation. A drive means, such as a motor, as at 9, is provided to cooperate with a sprocket 10, by any interlocking gear means, as necessary to provide a controlled rotation of the outer cylinder 2, and its internally disposed components. , at a controlled rotation, usually within a range of 1 to 10 rpm. The base means 8 is formed from a series of struts, as at 11, and is generally designed to be mounted on shock absorbers, as at 12, to dampen vibrations and decrease the operational noise of the apparatus.
    [0048] The outer cylinder 2 extends substantially over the entire length of the apparatus, with the exception that at the outlet end, opposite inlet 14, the drum has a door 28, for inspection of the invention by an operator or mechanic.
    [0049] The outer cylinder 2 and the inner cylinder 3 are attached to each other for simultaneous rotation of the rotating drum metal retriever. Some optional modifications can be made to the inner cylinder. For example, at inlet 14, openings can be placed through its walls so that sufficiently small material is removed from the process at first so that it can pass through the wall and into the screens 35a, 35a. Similarly, in the first compartment 15, the inner cylinder may be provided with perforations to allow the particulate material to pass through the region between the outer cylinder 2 and the inner cylinder, whereby the material will be transferred, as discussed above, to the classification screens 35, 35a.
    [0050] To conduct the process of the invention, the block material is fed to the inlet compartment 14 by an equipment, a hopper, or a vibrating conveyor, not shown in the drawing. On entry of material into the inlet compartment, the clods are controlled with respect to the waves, because of the larger diameter of the inlet compartment than in any other part of the apparatus where the inner cylinder 3 is present. The block material is metered into the crushing compartment 16 by a combination of the teeth 20, in a helical arrangement in the inlet compartment, and the helical vanes or ribs 13 in the first compartment 15. The crushing means 23 provides positive action to reduce the large clods, which vary in size and hardness. The crushing means 23 is of substantial length and diameter, and includes a segment, or back, having a significant length, as in crusher 24, which is generally disposed very close to the bottom surface of the inner cylinder 3, and which may include a series of ribs 26 and longitudinal slits 26a so that the material fed in this region will be substantially ground, by means of the large weight of the roller, to a much finer size. This crushing means is suspended by its head towards one end and is turned by its back by gravity during rotation of the cylinder.
    [0051] The inlet end, or head, of the crushing means includes a suspension means 29, as can be noted, for pivotal rotation within the inner cylinder 3, as a result of the rotation of the inner cylinder 3, during operations of the device. The suspension means has disk 29a, shown before it. The disc occupies the inner cylinder and has an opening formed by inwardly pointing teeth 29b. The central opening admits block material after the teeth and into the crushing medium. Outside teeth 29b, the disc has a plurality of partially annular slots 29b. The slits are adjacent to the friction chamber and allow block material, less than the height of the slit, to pass into the crushing medium. The disk separates adjacent slits using struts 29d, generally having a width proportional to the height of a slit.
    [0052] Moving to the rear of the disc, the suspension means 29 has an integral bearing, to allow rotation of the crushing means 23, at a different rotation than that of the inner cylinder. The suspension means 29 incorporates a housing, generally configured in a triangular or other shape, and has connected to it at its apexes a flexible connecting means, such as the chains 31. The chains 31 are fixed by means of connectors on insulated parts. and stiffened from the inner cylinder 3 to suspend the flexible pivoting end of the crushing means 23 approximately in the center but still flexible in its mounting on the apparatus. In this way, little interference is provided against the movement of the block material by means of the conveyor vane 13, in the vicinity of the second compartment, or crush 16. The block material, which passes through the block crush compartment 16, is reduced by middle of the serrated crushing means 23 to a size which is generally then reduced in the friction chamber to a size below that of the openings in the friction chamber 17. The crushing section provides a positive action in reducing large clods to a much smaller size, by the action of the crushing ribs 26 and adjacent ribs 26a.
    [0053] Following the procedure described above, the ground material is again forced by the additionally fed volume of material, the helical vane 17a, or perhaps by a slight inclination in the arrangement of the inner cylinder 3, to the region of the friction chamber 17 , in which further particle size reduction will occur. At this location, inner cylinder 3 is perforated and these particle sizes, usually less than 1.9 cm (3/4 in), pass into the intermediate space between outer cylinder 2 and inner cylinder 3, and are moved through of the continuous vane 37 further longitudinally along the apparatus, returning towards the inlet compartment. This material, larger than the size of the openings 36, is lifted by means of the paddles 33, and is then dropped onto the surface of the inner cylinder for further breakage.
    [0054] Following breakage, the smaller material, usually metal oxides, passes between the inner cylinder and outer cylinder to the sorting section near the first compartment. In the case where a lot of oversized material accumulates in the friction chamber 17, then when the depth is sufficient, the oversized material accumulates and can be removed through port 28. Screens 35, 35a use a perforated plate or a woven wire mesh, with openings to meet fine and coarse application specifications. Material is sorted by a single or multiple sorting systems, which automatically recirculate pieces that are larger than specifications through the material collection outlet 34. Openings are provided by wall 34a to allow material to be returned. And, a dust collection cover closes the sorting section, where a controlled air velocity removes fines and sorts material.
    [0055] The rotation speed of the rotating drum and metal retriever of the present invention is usually from about 1 to about 10 rpm, preferably from about 4 to about 10 rpm, depending on the particular application. The drum can also be operated in batch mode.
    [0056] It may also be noted in this application that the various sections of the inner cylinder can be manufactured from segmented components, as noted in the previous patents of the same applicant, and which are incorporated by reference in this specification, in which the segments of the inner cylinder may be formed of a rectangular but arcuate shape, having a segment of a rib, or helix, formed integrally with them, and also having a segment of a vane formed therewith, so that when the sections are manufactured, by means of interlocking together, as explained in the prior art, form the uniform inner cylinder of this rotating block crushing drum.
    [0057] Special aspects include crushing, turning, washing, sieving and sorting in the autonomous unit. Recirculating means for automatic screening and removal of debris, or automatic metal discharge, are also provided and for which no operator is required. The inner cylinder of the frame can be at least partially formed from cladding segments, as explained, as shown in the earlier patents.
    [0058] From the above-mentioned description, a drum of rotating means and a metal retriever have been described. This drum is uniquely capable of reducing and separating metals from slag, sand, sludge and oxides after metal production operations. It also separates metals and slag, sand, sludge and oxides into different streams for reuse. This drum and its various components can be manufactured from many materials, including, but not limited to, ferrous and non-ferrous metals, their alloys, polymers, high-density polyethylene, polypropylene, nylon, and composites.
    [0059] Variations or modifications in the object of this invention may occur to those skilled in the art, by review of development, as described. Such variations, if within the scope of that development, are intended to be encompassed within the principles of this invention, as explained in this specification. The description of the preferred embodiment, in addition to the illustration in the drawings, is presented for illustrative purposes only.
