    Background of the invention
    [0001] This invention relates to an installation to transfer solid particulate material with the aid of pressurized air flow in a loading container, which can be a storage container, a processing tank or other similar container. Even more particularly, the present invention relates to a set for transferring solid pelleted material, such as a catalyst substance, in a loading container, where the pelleted material generates dust during the transfer process.
    [0002] Many industries require transportation or supply of solid particles from the storage area or distribution container in another storage container or a processing tank. One such industry is a chemical industry where predetermined quantities of solid pellets are loaded into a processing container or converter. For example, sulfuric acid production plants use a vanadium catalyst, which is supplied in pelleted form in bags or barrels. The catalyst pebbles, therefore, need to be loaded into the converter or container where a chemical reaction occurs for gas generation to occur.
    [0003] Conventionally, acid processing tanks are vertical containers with a closed top. A plurality of levels or catalyst beds are contained in each converter container. The loading takes place through the top of the converter in the first catalyst bed and through the opening in the side wall of the converter in lower beds. During the loading operation, the catalyst pellets, being supplied by gravity, generate a significant amount of dust. People who carry out the loading operation must use masks, respirators and similar protective equipment to avoid breathing in the dust that strongly permeates the area where loading takes place.
    [0004] Similar conditions exist in loading operations for other solid particles, for example, when loading grain into silos and other storage facilities. The loading space must be equipped with adequate ventilation to minimize the retention of dust particles in the loading area and the generation of health risks in those areas.
    [0005] A useful assembly for handling solid particulate material is disclosed in U.S. Patent No. 7,635,011, which teaches the use of a pressurized container to retain a predetermined amount of solid material. A transfer hose connected to the container carries the solid material to a loading container, be it a processing tank, a storage container or any other similar container. A discharge nozzle carried by a distant end of the transfer hose has a plurality of perforations that allow the removal of dust particles by suction from the discharge nozzle. A separate dust removal hose is attached immediately adjacent to the discharge nozzle to remove dust particles from the discharge nozzle. The nozzle is also connected to a dust collection container. A vacuum assisted suction force is created in the dust collection container to facilitate the retention of dust particles generated during the transfer of solid material by the discharge container and transport of dust particles away from the discharge opening of the discharge nozzle. in the dust collection container. Although the assembly according to the '011 patent works satisfactorily in many circumstances, the need for better control of the transfer process has been noted to move the solid particulate material through the transfer hose. In addition, it has been found that there may be an improved dust holding device that can be used in the system.
    [0006] The present invention contemplates the elimination of the disadvantages associated with the previous project and the provision of an improved loading system that improves the control over the transfer process for solid particulate material, while improving the dust collection capacity. Summary of the invention
    [0007] It is, therefore, an object of the present invention to provide an improved loading system for transferring solid pelleted items from a storage facility to a loading container, thereby preventing the spread of dust in the loading area.
    [0008] It is another object of the present invention to provide an improved loading system for moving solid pelleted items with the help of regulated air pressure from a storage container to a processing tank.
    [0009] It is another object of the present invention to provide an assembly for loading sulfuric acid catalyst pellets, while removing dust generated by the friction of pellets before dust escapes from the loading and transfer hoses.
    [00010] It is also an object of the present invention to provide a delivery system for solid particulate material, in which dust particles are collected in detachable bag filters mounted on the dust collection container.
    [00011] These and other objects of the present invention are achieved by providing a system for the supply of solid particulate material, for example, catalytic pellets for loading. The system comprises a pressurized container or container configured to retain a predetermined amount of the solid particulate material. A source of pressurized gas retains a predetermined pressure inside the pressurized container to facilitate the movement of particulate material through the container and within a transfer hose. The pressure inside the container can be manually or automatically controlled using a control panel. The pressure created in the container facilitates the movement of the particulate material through the transfer hose to a distant end of the same, where a discharge nozzle is mounted.
    [00012] As the particulate material moves through the transfer hose, the pellets collide with each other and create dust particles, which must be removed before loading the pellets for processing in a catalytic converter or other tank outside the system . A balanced vacuum source creates a slight vacuum in the discharge nozzle assembly to remove dust particles from the transfer hose. The removed dust particles are sucked into a dust collection container, where they sit on the bag filters suspended in the dust collection container in the flow path of the dust collection hose and an exhaust pump or fan. .
    [00013] Since dust particles often contain valuable recyclable material, dust particles are collected from bag filters by blowing air through the sleeves using an auxiliary compensation tank. The expelled dust particles fall by gravity at the bottom of the dust collection container and are removed from it in a container positioned below the dust collection container.
    [00014] The balance between the pressurized container and the vacuum suction of the dust particles is maintained to facilitate efficient delivery of the dustless pelleted material to the desired processing tank. Brief description of the drawings

    [00025] Turning now to the drawings in more detail, the system of the present invention is designated by the number 10 in figure 1. As can be seen in the drawing, the system 10 comprises a pressurized vertical container 12 which has a lower discharge 14 in fluid communication with a transfer hose 16. The transfer hose 16 is provided with a discharge nozzle assembly 20 at its far end. A dust removal hose 22 is in fluid communication with the discharge nozzle assembly 20. Dust hose 22 is connected to the discharge nozzle assembly 20 upstream of a discharge opening 98 of the discharge nozzle assembly 20. The dust removal hose 22 is operationally connected to a dust collection container, or container 26, and is there in fluid communication. A chamber 28 is formed in the dust collection container 26.
    [00026] The pressurized container 12 is provided with an upper lid 30 which allows loading of the container 12 from the top. The items to be transferred, for example, the catalyst pellets 38, are loaded by gravity into the vertical container 12. A hose 32 fluidly connects the container 12 with a source of compressed air (pressurized) supply (not shown). A regulating valve 33 is mounted on the hose 32 to regulate the supply of pressurized air inside the container 12. A pressure indicator 35 is operationally connected to the container 12; the pressure indicator 35 is configured to detect the pressure inside the container 12 during the loading operation. The container 12 is oriented vertically to facilitate the movement of the solid particulate material into the container 12 from the top 34 to the bottom 36 thereof.
    [00027] The bottom part 36 of the container 12, if desired, can be formed as an inverted cone to facilitate the movement of the pelleted solid material inside the container 12 towards the apex of the cone, which serves as a discharge outlet for the container 12. As can be seen in figure 1, the solid particles occupy the bottom of the container 12, with the upper part 34 being filled with pressurized air to push the pellets down and into the discharge 14 and then into the hose. transfer valve 16. A gate valve 40 is positioned at the interface of the discharge opening 14 and the transfer hose 16 to regulate the movement of solid particles from the container 12 downstream into the transfer hose 16. The gate valve 40 is moves between an open position and a closed position in response to a control signal from a control valve 42 mounted in operational relation to the air supply hose 32 and the gap regulating valve 33.
    [00028] The container 12 is schematically shown to be at rest on a plurality of support legs 43 to allow the bottom 36 of the container 12 to be raised above the hose 16. The height of the support legs 43 differs depending on the types of design of container used.
    [00029] The solid pellets 38 move through the lower discharge 14 into the hose 16 in the direction away from the container 12. The air pressure of the loading side 15 of the container 12 is about 177 1 / s (375 cubic feet) per minute - EMC), pushing pellets 38 into the container 12. The pressure inside the container 12, maintained by the compressed air supply, as detected by the pressure indicator 35, is maintained at a level between 34.45 kPa (5 psi) and 103, 35 kPa (15 psi). In one of the preferred embodiments, that pressure is about 55.12 kPa (8 psi) to start the movement of the pellets 38 of the container 12 into the transfer hose 16. The pressure in the discharge 14 is maintained at a level sufficient to allow the movement of pellets 38 through the transfer hose 16 towards the discharge nozzle assembly 20. Although the pressure in the transfer hose 16 and the container 12 is necessarily different, depending on the material being transferred by assembly 10, one of the modalities of the The present invention for the transfer of sulfuric acid catalysts provides for pressurization of the container from 34.45 to 124.02 kPa (5 to 18 psi). The discharge 14 at the bottom of the container 12 opens when the predetermined pressure is reached. In one aspect of the invention, a compressor is used that generates up to 188.8 1 / s (400 cubic feet per minute - EMC).
    [00030] To facilitate the capture of dust particles and the movement of dust particles in the dust collection container 2 6, system 10 provides the use of a vacuum exhaust pump 50 connected to the interior of the dust collection container 26. A vacuum source (not shown) can be a vacuum truck, which is delivered on site and connected to the vacuum pump 50 by a vacuum supply hose 52. A vacuum control valve 54 is mounted on the supply hose vacuum 52. An exhaust hose 56 is connected to the top of the dust collection container 26. An exhaust valve 58 is mounted downstream of the exhaust pump 50 on the exhaust hose 56.
    [00031] As the pelletized items 38 move through the container 12 in the hose 16, they necessarily strike against each other; friction causes small particles to break from the pellets 38, generating dust that also travels through the container 12 and the transfer hose 16. The small solid particles then move along the transfer hose 16 and reach the nozzle assembly. discharge 20. A slight vacuum of about 0 to 34.45 kPa (0 to 5 psi), in the discharge nozzle assembly 20, creates a large expansion of gas up to about 1652 1 / s (3500 CFM). That air travels over the material being transferred by the discharge nozzle assembly 20, so that dust particles are captured by the vacuum and pulled into the dust removal hose 22 and then into the container dust collection 26.
    [00032] Sometimes an operator who loads pelletized material 38 into a container, for example, an oil processing container (not shown), detects that pellets 38 exit discharge nozzle 20 at a higher speed than necessary, and that the dust content in the gas has increased. Such observation allows the operator to determine that the speed of displacement of the pelleted material by the transfer hose 16 is very high. To better regulate the discharge speed of the pellets, the system of the present invention provides for the use of a regulating door 60, which moves between a closed position and a plurality of partially open positions.
    [00033] Regulator port 60 is mounted on the discharge nozzle assembly 20 which rotates around a pivot point 62 in the direction of arrow 63. Regulator port 60 can be rectangular in shape, as shown in figures 4 and 8. A the handle 64 is attached to an external surface 61 of the door 60 to allow the operator to manually open the door 60 and thereby reduce the vacuum force by pulling the pellets by the discharge hose 16. The door 60 can move to a position fully open or a plurality of partially open positions, giving the operator control over the discharge speed of the pellet at the exit point 98.
    [00034] As can be seen in figure 9, the discharge opening 98 is formed in a discharge nozzle plate 100. The discharge nozzle plate 100 surrounds the discharge opening 98, through which the pellets 38 exit the system. 10. Regulating door 60 is formed by a recess 102 on an internal contact surface 63 thereof. A plurality of spaced protruding members 104 is provided on the contact surface of the discharge nozzle plate 100. Since any of the protruding members 104 is aligned with the recess 102, a counterpart engages with it, the door 60 opens in position selected, allowing the discharge opening 98 to be fully closed, partially open or fully open, according to the operator's choice.
    [00035] The dust collection hose 22 is fluidly connected to an inlet opening 27 formed in the dust collection container 26. A plurality of dust collection members 70 is suspended in the dust collection container 26 above an opening inlet dust above inlet opening 27. Dust collection members 70 are suspended in dust collection container 26 in the suction flow path between dust collection hose 22 and exhaust pump or fan 50.
    [00036] Each of the dust collection members 70 comprises a structure 72, which can be formed by a thin rod bent in a generally U-shaped configuration. A dust bag filter 74 is stretched over the structure 72 and is remarkably fixed at the top by a clamp or elastic band 76. The bag filter 74 is formed from a flexible porous material with small openings 75 that allow air to circulate through the dust sleeve during the capture of dust particles in the outside of sleeve 74.
    [00037] As the vacuum created by the vacuum source pulls into the chamber 28 of the dust collection container 26, the dust particles settle outside the bag filters 74, while the dustless air exits through the exhaust hose 56. It should be noted that dust particles can contain valuable materials, for example, silver (Ag), which is used in some catalysts.
    [00038] The system of the present invention comprises a means for expelling and capturing or collecting dust particles for recycling or disposal. As can be seen in figures 1 and 5, a compensation tank 80 is operationally connected to a compensation hose 82 mounted inside the chamber 2 8. The compensation tank 80 is connected to a source of compressed air (not shown) through from a supply valve 84 and to a control panel 200 of system 10 via a compensation control valve 86.
    [00039] The compensation hose 82 has channels that connect the compensation hose 82 to the dust collection members 70. As dust is collected outside the sleeves 74 and the exhaust air flow through the exhaust hose 56 decreases, the The system operator can detect that the sleeves 74 have collected dust that prevents air flow through the sleeves. Periodically, the operator can close the valve inside the transfer hose 16 and turn off the exhaust pump 50. The vacuum valve 54 is closed, thereby isolating the dust collection container from the rest of the system. If desired, the closing of the valves and the supply of vacuum can be carried out automatically by detecting a certain pressure through the exhaust hose 56 using the control panel 200.
    [00040] The operator then opens the supply of compressed air through the compensation tank 80, blowing the compressed air inside the sleeves 74. The dust particles, which had deposited on the sleeves 74, are expelled from the sleeves 74 and fall by gravity to the bottom 29 of the dust collection container 26. Dust particles 87 are collected in the conical bottom 29 of the container 26. The operator can open the bottom door 88 on the bottom 29 of the container 26 and let the dust particles 87 fall into a barrel 89 positioned under door 88. The collected dust particles containing valuable metals and other materials can be sent for recycling and manufacture of catalyst pellets, or safely disposed of.
    [00041] The modality of the present invention, the system 120, shown in figures 5 to 8, is quite similar to the modality shown in figures 1 to 5 and 9, except that, in system 120, the supply of compressed air supply on the side The inlet of the transfer hose 16 and the pellet container 12 is carried out automatically without human intervention, using the control panel 200. In both modalities, substantially all the dust particles, or a significant amount of it, is deflected from the opening discharge 98 and exhaust to the atmosphere. During a catalyst loading operation, the end of the discharge nozzle 98 is placed in the converter and the catalyst is distributed as needed.
    [00042] The loading assembly of the present invention allows cleaning of catalysts or other pelleted solid particles and removes dust from the loading hoses before escaping to the neighboring area or reaching the processing containers, catalytic converters, storage containers and the like . A careful balance must be observed between the amount of pressure created in the container 12 and the dust removal hose 22. Likewise, if the discharge nozzle 20 is selected for high-speed discharge, the dust particles cannot have the opportunity to be directed to the flow that moves towards the hose 22.
    [00043] System 10 and system 120 allow the control of the catalyst to be loaded into container 12, as well as the control of vacuum suction by increasing the revolutions of the exhaust fan or pump 50 in order to create a sufficient amount of low pressure at the precise point in the discharge assembly. The dust particles separated from the solid pellets are diverted from the discharge outlet to the dust collection hose 22 and the dust collection container 26, thereby allowing the dust particles to be collected, stored and recycled.
    [00044] These main control points balance the loading process and create a truly dust-free supply of the catalyst for a chemical reaction outside the system of the present invention. As the pelleted material moves at the speed selected by the transfer hose, the dust particles separate from the pelleted material and are then redirected from the discharge opening 98 to the dust collector. The time and speed of displacement of the pellets by systems 10 or 120 allows to obtain the maximum separation of the dust particles, depending on the size and type of pelleted material.
    [00045] It should be noted that the vacuum source must not overload the positive air compressor by supplying compressed air through the supply line 32. The pressure in container 12 is detected and controlled using pressure indicator 35 so as not to exceed the vacuum force required for proper particle separation. In one aspect of the invention, the inlet pressure of about 34.45 kPa (5 psi) at the time of delivery of the pellets in container 12 and the control of the vacuum exhaust fan 50 allows to create the balance necessary for maximum collection of dust particles without sacrificing the supply of pelleted material for loading. In one aspect, the dust collection container 26 may have an ability to move 1416 1 / s (3,000 cubic feet per minute) of air flow.
    [00046] Obviously, the vacuum generated in hose 22 and the pressure values in container 12 can be different for different types of solid particulate material.
    [00047] Many changes and modifications can be made to the device of the present invention without departing from its spirit. Therefore, I ask that my rights to the present invention be limited only by the scope of the attached claims.
