    1449926 Centrifugal separators DONALDSON CO INC 15 Feb 1974 [28 Feb 1973] 7023/74 Heading B2P A centrifuge for separating particulate matter from a fluid comprises a stationary enclosure 12, Figs. 1 and 2, having fluid inlet means 44 and outlet means 16, a rotor 23 mounted within the enclosure for rotation about a predetermined axis, the rotor being constructed to receive uncleaned fluid from the inlet means and to deliver cleaned fluid to the outlet means and defining about the rotational axis a plurality of concentric passages for the fluid, and means associated with the rotor for causing fluid flowing therethrough to attain maximum angular momentum after leaving the plurality of passages. The rotor 23 is secured by screws 25 to a support plate 22 on the end of a rotatable shaft 19. The upper edge portion of the side wall 26 of the rotor is provided with threaded bores which receive Allen screws 27 having liquid flow restrictive bores 28. An annular top plate 29 is removably secured to the side wall 26. An annular baffle plate 32 is spacedly suspended from the plate 29 and defines with the side wall 26 a flow restrictive annular passage 35 disposed at the maximum radial point within the rotor 23. An annular member 36 of L-shaped cross-section is supported on the underside of baffle plate 32. The rotor also comprises a removable cartridge 37 defined by a liner tray having inner and outer cylindrical walls 38a, 38b and a bottom 38c. Disposed within the tray above spacers 38d are four particle separation stages or cartridge elements 39a-d each consisting of a flat layer 41, Fig. 5, of liquid impervious material, e.g. treated heavy paper or flexible cardboard, which is alternately wrapped with a corrugated layer 42 of the same materials, the size of the corrugations determining the spacing between the layers 41 and hence the depth of liquid flow therethrough. The separation stages 39a-d have progressively smaller spacing between the layers 41 to accommodate particles of varying size and shape. Stages 39a and 39d rest respectively on stages 39b and 39c, and a liquid impervious cylindrical casing 43 sealingly engaged with annular member 36 is disposed between the stages 39a, 39b and 39c, 39d. In operation, liquid to be filtered is delivered from a spout 44 into the cup defined by the inner wall 38a of liner tray 38 and, as indicated by the arrows, moves successively over the wall 38a; through the stages 39a-d, where the particulate matter is separated out and settles on the outer walls of the passages defined between the layers 41; through the annular passage 35 at which it reaches maximum angular momentum; between the baffle plate 32 and top plate 29; around and over the plate 29; and finally downwards between the rotor 23 and the surrounding casing 12 for discharge through a tangential outlet 16. The restrictive bores 28 serve to drain liquid from the rotor after the supply through the spout is shut off for servicing or cartridge replacement. In a modification, Figs. 3 and 4 (not shown), there are no superposed separation stages, the latter being concentrically arranged and extending the whole length of the rotor.

    each previous separator along the fluid flow exceeds the distance between the channels of each subsequent separator. In this case, the separators are replaceable cartridges. . IQpoMe additionally, each replaceable cartridge is formed by cylindrical shells of a liquid-impermeable material, between which corrugated gaskets are located, the corrugations of which are parallel to the rotor axis. Each replaceable cartridge may be formed by a tape of a laminate having corrugations and at least one layer of a liquid-tight sheet material. In addition, at the bottom of the rotor, the ribs are reinforced radially, and the separators. installed on the latter. Ribs are placed between the disk and the upper end surface of the separators. FIG. 1 schematically shows a centrifuge for separating solid particles from a liquid, front view; in fig. 2 shows section A-A in FIG. in fig. 3 - replaceable cartridge, partly in cross section; in fig. 4, the second embodiment of the centrifuge is a front section view; in fig. 5 is a section bB in Fig.4. The centrifuge (Fig. 1, 2) contains a cylindrical rotor 1 mounted in the upper part of the vertical shaft 2 on the supporting flange 3, the central receiving chamber 4 for liquid located inside the rotor, mounted inside the rotor coaxially cylindrical bulkheads to form vertical chambers 5 , 6,7,8 for cleaning the fluid, the disk 9 mounted on the partitions is mounted to the ring cover 10 by means of screws 11c nuts 12, while the latter are located on different diameters and are equipped with separating washers installed between the cover 10 and the disk 9. The end of the disk 9 does not reach the inner surface of the rotor shell 1, forming an annular throttling slot 13 for the withdrawal of the purified liquid. The slot 13 is located above the last vertical chamber 8 along the liquid movement. On a smaller diameter, a ring 14 is attached to the disk 9 with screws 11, having a L-shaped cross-section, the vertical wall of the ring being at an acute angle to its horizontal wall, the ring of which is attached to disk 9. The lid 10 is fixed on the rotor side 1 with the ropes 15 so that the lid can be removed together with the disk and the ring 14 when the screws are unscrewed. The cylindrical partitions do not reach the bottom 16 of the rotor, which is located with a recess in the center of the rotor and is attached to the support flange with 3 screws 17. The upper part of the shell of the ptor 1 is thickened and has threaded holes in which screws 18 (Allen) are screwed, and each screw has a hole 19 for limiting the amount of fluid flowing out of the rotor shell to the outside. In vertical chambers 5, 6, 7, 8 for cleaning the fluid there are separators with many concentrically arranged channels, and the separators are ennye cartridges 20. Interchangeable cartridges are enclosed in a housing having a vertical annular walls 21 and 22, the height of the latter is slightly larger than the first. From the bottom, the housing has a bottom 23, which is made integral with the wall 22 and is adjacent to the wall 21, but is not air-guided on it. On the inner surface of the bottom 23 is placed radially ribs 24, while the separators are installed on them. Each replaceable cartridge (Fig. 3) is formed of cylindrical shells 25 of liquid-impermeable material, between which are corrugated gaskets 26, the corrugations of which are parallel to the rotor axis 1. The distance between the channels of each previous one along the movement of the separator liquid exceeds the distance between the channels of each subsequent the separator in the vertical chambers 5, 6,7, 8, which allows separating the suspensions with rims having different sizes and shapes. As a separator material, it is advisable to use thick paper or flexible cardboard treated to impart resistance to water and oil. The dimensions of the corrugations determine the distance between the shells 25 and thus the amount of flow of the Liquid flowing between them. It is advisable that the elements forming the separation zones be attached to the body of the cartridge so that they can be removed as a single unit. The chambers 5 and 6 have the same cross section and are located one above the other directly adjacent to the vertical wall 21. The ribs 27 are placed between the disk 9 and the upper end surface of the separators to allow the fluid to flow freely. Between chambers 5, 6, and 7, 8 there is an intermediate liquid-free cylindrical partition 28, which in its upper part is sealed by a ring 14 and also serves during the assembly of the rotor. To center the cover 10 with the Disk 9. Replaceable patro 20 can also be formed from a laminate having corrugations and at least one layer of a liquid-tight sheet material. The centrifugal rotor 1 is located in the casing 29 with the cover 30 and the bottom 31. There is a central hole in the casing bottom in which a fixed sleeve 32 is installed through which the rotor 1 shaft 2 mounted in the bearings 33 is mounted. The conical part 34 of the bottom serves for free flow of fluid in the drain pipe 35. The centrifuge operates as follows. The separated liquid is fed into the rotor 1 through pipe 36, which is attached to the top of the rotor shell with nuts. The fluid passes through the central receiving chamber 4 and rises up along the vertical wall 21, into the separation zone of the vertical chamber 5. A further rise of the fluid is limited by the disk 9. The partition 28, the upper end of which is hermetically packed into the ring 14, moves the fluid outward in the radio direction, therefore, the liquid ZD is down through the separators of the vertical chambers 5 and 6, where the impurities that settle on the outer walls of the channels are separated. The fluid coming out of chamber 6 moves outward in the radial direction between the crown ribs 24 and then rises upward, passing through the separation zones of chambers 7 and 8. Finally, the liquid passes through the annular gap 13. In this case, the liquid passes through the annular gap 13. the separating cartridge, since the main amount of liquid is prevented from flowing through channels located on a smaller radius, which results in maximum separation efficiency. Next, the liquid leaving the slot 13, d radially to the center of the rotor between the disk 9 and the lid 10 until it reaches the inner hole in the lid 10, the liquid is thrown from the orifice by centrifugal force to the periphery of the rotor and flows down the annular gap between the outer surface of the rotor 1 and the casing 29 in the drain cartridge 35. Before stopping the centrifuge to clean or replace the cartridge, it is necessary to first release the liquid from the chambers of the cartridge, while allowing the rotor to be allowed free rotation for a certain period of time with connection opodvod conductive line (not shown in the drawing). After the level of the fluid in the rotor reaches the level determined by the height of the bottom surface of the cap, the outflow of fluid from the rotor examined above is prevented, and the remaining liquid in it will drain through the holes 19 until no liquid will remain in the rotor; FIG. 4 and 5 is shown in another va; a pattern of the described centrifuge, which is practically similar to the centrifuge shown in FIG. 1 and 2 in terms of the design of the bearing assembly, the housing and the means for supplying and discharging the liquid to be separated. The centrifuge (Fig. 4, 5) contains a rotor 37, the bottom 38 of which is fixed to the support flange 3 of shaft 2. In BepjfHeft part of the rotor shell, screws 39 (Allen) are fixed with throttling holes 40. An annular cap is attached to the shell of roTopia 37 screws 41 42. A thread 43 is made on the shaft 2 entering into the rotor, and the central hole in the annular plate 44 has a diameter corresponding to the diameter of the thread 43. The plate 44 is mounted on the bottom 38 and has radially arranged holes 45. The cylindrical sleeve 46 is coaxial with the shaft 2 and fixed its lower part on an annular plate 44. A cylindrical partition 47 is attached to the plate 44 along the outer diameter, the lower end of which is located at the upper edges of the ribs 48 fixed to the bottom of the rotor 37. A horizontal flange 49 is installed in the upper part of the partition 47 to form between it and the side of the rotor of the annular gap 50. On the lower surface of the flange 49 are fixed ribs 51, and on its upper surface a disk 52 is fixed, the inner diameter of which is less than the diameter of the sleeve 46. When REMOVABLE cover with threads From the new end of the shaft 2, the plate 44 can be removed together with the arms attached thereto. To press the plate 44 to the bottom 38 of the rotor serves as a sleeve 53, which is attached in the center to the upper surface of the string 44, and a threaded cap 54, which is screwed onto the threaded end of the shaft 2. Between the ribs 48 and 51 are vertical chambers 55, 56 and 57, which together form a separation cartridge, similar to the cartridge 20 described above (Fig. 3), with the distance between the separator channels gradually decreasing from chamber 55 to chamber 56, to chamber 57. A partition 58 is located between the separation zones of the chambers 55 and 56, the lower the end of which is hermetically sealed Izhat to the bottom 38 of the rotor 37, so that the liquid from the separation zone of the chamber 55 into the chamber 56 can only get through the gaps between the ribs 51. Similarly, between the chambers 56 and 57 there is a partition 59, the upper end of which is privat to the flange 49, as a result of which from the chamber 56 can get into the chamber 57 only through the gaps between
    ribs 48, with the annular gap communicating only with the separation zone of chamber 57..
    The centrifuge operates similarly to the centrifuge of FIG. 1 and 2, while the liquid entering the centrifuge through the pipe 36 passes down through the holes in the crutch 42 and disk 52 and into the chamber formed by the sleeve 46 and the ring plate 44. From this chamber, the liquid first rises up through the sleeve 46, and then rtbrasavayas down disk 52 and glassTeo lio partition 47. Then the liquid fiSefe Yr6Styt through the hole 45, the gap between the ribs 48 and falls into the separation zone of the chamber 55. Then the cycle repeats. -
