A drain port 3 is provided on the left side wall of the shell 1 for discharging the separated liquid;

[0032] As an embodiment of the present invention, a centrifugal separation mechanism is further included. The centrifugal separation mechanism includes a support plate 16 fixedly connected to the inner walls on the left and right sides of the housing 1. A filter cartridge 13 is provided through the support plate 16. The filter cartridge 13 is rotatably connected to the support plate 16. A gear ring 17 is provided on the outer side of the filter cartridge 13. A drive motor 5 is installed at the upper end of the housing 1. The output shaft of the drive motor 5 extends into the interior of the housing 1 and is installed with a first gear 20. The first gear 20 is meshed with the gear ring 17. A plurality of separation holes are opened on the outer side wall of the filter cartridge 13.

[0033] As an embodiment of the present invention, a rotating disc 14 is further included. The rotating disc 14 is located inside the bottom portion of the filter cartridge 13. The upper end surface of the rotating disc 14 is a conical structure to facilitate the subsequent solid discharge operation after separation.

[0034] As an embodiment of the present invention, it also includes a lifting mechanism, which is used to move the rotating disk 14 up and down, so as to facilitate the removal of the separated solid matter. The lifting mechanism includes a reciprocating screw rod 23 that is rotatably connected to the lower end of the support plate 16. A moving block 24 is threadedly connected to the reciprocating screw rod 23. A hollow ring 18 is fixedly connected to the left side of the moving block 24. The filter cartridge 13 is located on the inner side of the hollow ring 18. The lower end of the hollow ring 18 is fixedly connected to a U-shaped linkage rod 15. The other end of the U-shaped linkage rod 15 is rotatably connected to the lower end of the rotating disk 14.

The upper end of the reciprocating screw rod 23 passes through the support plate 16 and is installed with a second gear 21 through a one-way bearing. The second gear 21 is engaged with the first gear 20. When the first gear 20 rotates in the reverse direction, the reciprocating screw rod 23 can be rotated through the second gear 21. When the first gear 20 rotates in the forward direction, the reciprocating screw rod 23 will not be rotated. During the centrifugal operation, the reciprocating screw rod 23 does not rotate, but during the subsequent separation operation, the reciprocating screw rod 23 rotates;

[0035] As an embodiment of the present invention, it also includes a clearing mechanism, which is used to backflush the filter cartridge 13 to avoid clogging of the filter cartridge 13. The clearing mechanism includes an L-shaped mounting plate 6 fixedly connected to the right side of the housing 1. The lower end of the horizontal portion of the L-shaped mounting plate 6 is rotatably connected to a rotating shaft 33. The rotating shaft 33 is connected to the reciprocating screw rod 23 through a transmission member 22. The transmission member 22 includes two pulleys, which are connected through a transmission belt. The two pulleys are respectively mounted on the rotating shaft 33 and the reciprocating screw rod 23. The vertical portion of the L-shaped mounting plate 6 is penetrated by a first piston cylinder 7. A first piston 36 that can slide left and right is provided in the first piston cylinder 7. The lower end of the rotating shaft 33 is fixedly connected to A driving plate 34 is rotatably connected to a driving rod 35 at an eccentric position at the lower end of the driving plate 34. The other end of the driving rod 35 is rotatably connected to the left side of the first piston 36. A plurality of air holes 19 are provided on the inner side of the hollow ring 18. The right side space of the first piston cylinder 7 is communicated with the outside world through a one-way port. The right side space of the first piston cylinder 7 is communicated with the hollow ring 18 through a one-way tube 8. A one-way valve is installed inside the one-way port and the one-way tube 8. The one-way valve inside the one-way port flows from the right rear to the front. The one-way valve inside the one-way tube 8 flows in a one-way direction for the first piston cylinder 7 to enter the hollow ring 18 in one direction. In this way, when the first piston 36 moves left and right, a one-way gas flow between the outside world, the first piston cylinder 7 and the hollow ring 18 can be generated, and the gas is finally discharged from the plurality of air holes 19.

[0036] As an embodiment of the present invention, the right side of the first piston cylinder 7 is fixedly connected to the second piston cylinder 9, and a second piston 38 that can slide left and right is provided in the second piston cylinder 9. The first piston 36 and the second piston 38 are fixedly connected by a connecting rod 37. The upper end part of the filter cylinder 13 is provided with a hollow disk 26, and the hollow disk 26 is fixedly connected to the filter cylinder 13 through multiple connecting strips 27. A plurality of third piston cylinders 28 are fixedly connected to the outside of the hollow disk 26, each third piston cylinder 28 is connected to the hollow disk 26, and a piston column 29 is slidably connected in each third piston cylinder 28. A cylindrical groove 31 is provided at the end of each piston column 29 away from the hollow disk 26, and a slidable impact rod 30 is provided in each cylindrical groove 31. Each impact rod 30 is elastically connected to the corresponding inner wall of the cylindrical groove 31 by a spring 32, and the right side space of the second piston cylinder 9 is connected to the interior of the hollow disk 26 through a connecting pipe 10.

[0037] In the present invention, during centrifugal operation, the output shaft of the drive motor 5 begins to rotate, driving the first gear 20 to rotate synchronously. The first gear 20 meshes with the ring gear 17. Therefore, when the first gear 20 rotates, it drives the filter cartridge 13 to rotate on the support plate 16. At this time, solid waste is fed into the filter cartridge 13 through the feed port 4. Under the action of centrifugal force, the water in the solid waste is ejected through the multiple separation holes on the outer wall of the filter cartridge 13 and flows along the annular intercepting plate 12 to the drain port 3 for discharge, while the solid particles remain in the filter cartridge 13. Due to the action of the one-way bearing, when the first gear 20 rotates in the forward direction, it does not drive the second gear 21 and the reciprocating screw 23 to rotate. Therefore, during the centrifugal operation, the reciprocating screw 23 remains stationary, the lifting mechanism does not operate, and the rotating disk 14 also remains in place. At the same time, since the reciprocating screw 23 does not rotate, the transmission member 22 does not drive the rotating shaft 33 to rotate. Therefore, the first piston cylinder 7 and the second piston cylinder 9 in the clearing mechanism do not operate and remain stationary.

[0038] After the separation operation is completed, when the remaining solid waste needs to be discharged, the driving motor 5 is reversed to rotate the first gear 20 in the opposite direction. At this time, the first gear 20 drives the reciprocating screw 23 to rotate through the meshing second gear 21. Since the moving block 24 is threadedly connected to the reciprocating screw 23 and slides under the guidance of the guide rod 25, the moving block 24 will drive the hollow ring 18 and the U-shaped linkage rod 15 to move downward first and then upward. During the downward movement, the driving rotating disk 14 follows the movement. With the downward movement of the rotating disk 14 and the guidance of the conical structure, the solid particles are finally discharged from the discharge port 11.

[0039] At the same time, due to the rotation of the reciprocating screw 23, the rotating shaft 33 is driven to rotate through the transmission member 22, and the driving plate 34 and the driving rod 35 at the lower end of the rotating shaft 33 drive the first piston 36 to slide left and right in the first piston cylinder 7. This movement generates a one-way gas flow, which enters the first piston cylinder 7 from the one-way port, then enters the hollow ring 18 through the one-way pipe 8, and is discharged from the multiple air holes 19, performing a backflush treatment on the filter cartridge 13 to prevent blockage. Since the hollow ring 18 is in a moving state and the filter cartridge 13 is in a rotating state, the blockage clearing operation is more comprehensive.

[0040] The movement of the first piston 36 also drives the second piston 38 to move in the second piston cylinder 9 through the connecting rod 37, and then continuously exchanges gas with the hollow disk 26 through the connecting pipe 10. The gas in the hollow disk 26 increases and decreases reciprocally. Each time the gas increases, the gas pushes the piston column 29 and the impact rod 30 to move in the third piston cylinder 28, allowing the piston column 29 to drive the impact rod 30 away from the hollow disk 26, and then allowing the impact rod 30 to impact the inside of the filter cylinder 13, generating a vibration effect, further assisting in cleaning the residual solid particles on the filter cylinder 13;

[0041] Finally, as the reciprocating screw 23 rotates, it returns to Figure 2 status, completing the overall operation.
