    [0023] The working principle of the extrusion separation and purification device (taking one cycle of extrusion separation as an example) includes:
    [0024] (1) Feeding and pre-compression: Materials such as kitchen and household garbage as well as other water-containing garbage, such as lees, vinegar residues, etc., enter the device through the feed hopper 14; at this point, the pusher 13 is in a retracted position, the piston rod of the oil cylinder 11 drives the pusher 13 to move toward the feed box assembly 2 along the guide rails 15, and the pusher 13 pushes the garbage into the feed box assembly 2; the garbage is pre-compressed into the cylindrical pre-compression chamber formed by the front end of the pusher 13 and the sieve cylinder-like side wall 21 so that a pre-compression function is completed.
    [0025] (2) Extrusion: The piston rod in the oil cylinder 51 of the anti-extrusion guiding assembly 5 and the guide post 53 move along the guide sleeve 52 and block the end of the main sieve cylinder 31. The piston rod in the oil cylinder 41 of the main extrusion guiding assembly 4 and the guide post 43 move along the guide sleeve 42 to further press the pre-compressed garbage into the main sieve cylinder 31, where a predetermined pressure is reached and the pressure is maintained to complete the extrusion function.
    [0026] (3) Discharge: The piston rod in the oil cylinder 51 of the anti-extrusion guiding assembly 5 drives the guide post 53 to move back to its original position, the piston rod in the oil cylinder 41 of the main extrusion guiding assembly 4 drives the guide post 43 to continue to move forward and discharge the dry materials through the discharge mechanism 32, and the wet-component materials are conveyed to the purification device 200 through the material passage opening 20 of the discharge mechanism 32 for purification.
    [0027] (4) Purification: After the wet-component materials enter the material trough 7, the motor 9 rotates, and the motor 9 drives the screw shaft 8 to rotate through the reduction box 10. Under the action of the screw shaft 8, the wet-component materials move toward one end of the material trough 7 along the sieve plate 16. During the movement, impurities and moisture in the wet-component materials enter the lower chamber 19 through the through holes 17 in the sieve plate 16 and are finally discharged through the second discharge port 24. The purified materials are discharged through the first discharge port 23.
    [0028] While the utility model is described in detail with reference to the general description and specific embodiments above, it is apparent to those skilled in the art that some modifications or improvements may be made based on the utility model. Therefore, such modifications or improvements made without departing from the spirit of the utility model will all fall within the scope of protection of the utility model.
