[0023] During use, the manure pump is connected to the manure inlet 61, the return pipe is connected to the return port 62, and the motor 4 is started. The motor 4 drives the screw rod 3 to rotate. Under the rotation of the screw rod 3, the pig manure in the feed barrel 6 moves axially along the screw rod 3 and enters the filter barrel. The pig manure in the filter barrel 2 moves axially along the filter barrel 2 under the push of the screw rod 3, and gradually forms an extrusion effect with the movable cover plate 12 to squeeze out the moisture in the pig manure. The moisture flows into the water collecting box 14 through the filter barrel 2 for collection; when the action force between the pig manure and the movable cover plate 12 is greater than the action force of the compression spring 11, the movable cover plate 12 moves along the end of the screw rod 3, and the dehydrated pig manure is discharged through the discharge port 51; after use, start the second The motor 13 and the second motor 13 drive the gear 16 to rotate, and further drive the filter cartridge 2 to rotate through the rack 21. During the rotation, the switch valve on the cleaning pipe 8 is opened, and water is sprayed through the cleaning pipe 8 to rinse the filter cartridge 2.

The pig manure in the filter barrel 2 moves axially along the spiral rod 3 under the push of the spiral blades. During the movement, the pig manure is affected by the changing pitch and the spiral blades, forming a huge extrusion force, so that the pig manure is mechanically dehydrated under the action of external force. The water flows into the water collecting box 14 through the filter barrel 2 for collection and reuse as liquid organic fertilizer; when the force between the pig manure and the movable cover plate 12 is greater than the force of the compression spring 11, the movable cover plate 12 moves along the end of the spiral rod 3, and the dehydrated pig manure is discharged through the discharge port 51, thereby realizing the dehydration operation of the pig manure; after use, the second motor 13 is started, and the second motor 1 3 drives the gear 16 to rotate, and further drives the filter cartridge 2 to rotate through the rack 21. During the rotation, the switch valve on the cleaning pipe 8 is opened, and the water flow is sprayed along the radial direction of the filter cartridge 2 through the cleaning nozzle 81 to rinse the filter cartridge 2, thereby avoiding the problem of a large amount of residues accumulating on the filter cartridge 2 and causing blockage. At the same time, the pig manure remaining on the filter cartridge 2 is scraped off by the cleaning brush 9. After long-term use, the operator opens the movable plate 72, and the internal situation of the filter cartridge 2 is convenient to check through the observation window 71, so as to facilitate the removal and replacement of the cleaning brush 9. The utility model provides a cleaning brush and a cleaning pipe to fully brush the surface and the inside of the filter cartridge during the rotation process, thereby achieving the cleaning effect of the filter cartridge, avoiding the problem of a large amount of residues accumulating on the filter cartridge and causing blockage, reducing the trouble of manual cleaning, and solving the problems of occupying land and polluting the environment due to direct drying, thereby improving work efficiency.
