[0029] The guide sleeve 7 is fixedly provided with a shaft groove a with two ends opened and slidably connected to the extrusion shaft 8;

[0030] The top of the extrusion shaft 8 is rotatably connected to a lifting platform 9, and a vertically arranged pressure push rod 10 is fixedly installed between the lifting platform 9 and the opposite surface of the injection cylinder 1;

[0031] A spinning column 11 is fixedly installed on the peripheral side of the extrusion shaft 8, and a spinning seal seat 12 is slidably connected to the inner wall of the sewage discharge barrel 5. The inner wall of the spinning seal seat 12 is transmission-connected and slidably matched with the extrusion shaft 8;

[0032] The rotary sealing seat 12 is fixedly provided with an axis groove b with both ends opened and slidably connected to the extrusion shaft 8. The cross sections of the axis groove a, the axis groove b and the extrusion shaft 8 are all regular polygons.

[0033] The bottom surface of the rotary sealing seat 12 is rotatably connected to the driving frame 13, the surface of the lifting platform 9 is transmission-connected to the driving frame 13 via a reverse linkage component, and an anti-cleaning component is arranged inside the extrusion shaft 8.

[0034] The reverse linkage assembly includes a coupling shaft rotatably connected to the side of the glue discharge box 4, a linkage gear 15 is fixedly installed on the peripheral side of the coupling shaft, a transmission gear plate 16 is fixedly installed on the bottom surface of the lifting platform 9, and a limit guide frame 17 slidably connected to the sewage discharge barrel 5 is fixedly installed on the bottom surface of the driving frame 13;

[0035] A T-shaped guide rod 18 is fixedly installed on the top surface of the limiting guide frame 17, and a driven gear plate 19 is slidably connected to the peripheral side surface of the T-shaped guide rod 18. The surface of the driven gear plate 19 is slidably connected to the glue removal box 4.

After the pressure pump 21 discharges air, the rate of rubber filtering through the rubber filter holes is accelerated. At the same time, the continuous high-pressure air discharge of the pressure pump 21 can effectively reduce the probability of the rubber filter holes being blocked, thereby maintaining the high filtering performance of the filtering and extruding device.

[0039] This device is mainly suitable for filtering and extruding waste plastic rubber materials. Before the extrusion operation, the spinning column 11 is fully lifted upward. During the upward lifting period of the spinning column 11, the waste plastic rubber materials to be extruded are injected into the centrifugal filter cartridge 6. When filtering the rubber, the motor 2 continuously outputs the rotation speed. After the motor 2 outputs the rotation speed, the centrifugal filter cartridge 6 can then perform the centrifugal filtering operation of the waste plastic rubber materials. When the motor 2 is working, the spinning column 11 periodically moves back and forth up and down. During the downward movement period of the spinning column 11, the bottom surface of the spinning column 11 is finally fitted with the rotary sealing seat 12, and then the rubber materials are extruded and filtered out. Through the setting of the reverse linkage component, when the spinning column 11 moves downward, the rotary sealing seat 12 can seal the bottom end of the centrifugal filter cartridge 6. When the spinning column 11 moves upward, the rotary sealing seat 12 can lose the sealing effect on the centrifugal filter cartridge 6, and the filtered impurities are centrifugally thrown out. The impurities centrifugally thrown out are finally discharged through the sewage discharge barrel 5 and the sewage discharge valve 23.
