[0024] By means of the above-mentioned structure or mechanism: through the staggered setting of the support cylinder 2 and the opening of the filter cylinder 4, impurities can be intermittently discharged into the filter box 1, so as to facilitate the squeezing of the impurities through the squeezing plate 9, and the inclined setting of the bottom surface of the filter cylinder 4 makes it easier for the impurities in the filter cylinder 4 to slide through the opening into the filter box 1.

[0025] A filter plate 8 is fixedly provided inside the filter box 1, and an extrusion plate 9 is slidably provided on the filter plate 8. The side of the extrusion plate 9 is fixedly connected to the side of the connecting rod 11 through a fixing rod 10. The connecting rod 11 is slidably provided in a through hole 12 opened on the side of the filter box 1. The side of the connecting rod 11 is fixedly connected to the side of the fixing plate 14 through an electric hydraulic push rod 13. The fixing plate 14 is fixedly connected to the surface of the filter box 1.

[0026] By means of the above structure or mechanism: in the process of processing impurities, the piston rod in the electric hydraulic push rod 13 drives the extrusion plate 9 to move through the connecting rod 11 and the fixed rod 10, and the extrusion plate 9 pushes the impurities so that the impurities are squeezed together, so that the sewage in the impurities can be squeezed out, the weight of the impurities can be reduced, and it is convenient for the staff to collect and process the impurities.

[0027] The working principle of this utility model is:

[0028] Before use, the device is set up to facilitate the injection of sewage into the device and the collection and treatment of sewage after impurities are treated. After the preliminary work is completed, the sewage flows into the filter cartridge 4, and the sewage flows out through the filter holes 15 on the surface of the filter cartridge 4, and the impurities remain in the filter cartridge 4;

[0029] When the control system controls the drive motor 7 to work, the output shaft of the drive motor 7 drives the gear 6 to rotate, and the gear 6 engages the gear rod 5 to make the support rod 3 drive the filter cartridge 4 to rotate, so that the opening on the side of the filter cartridge 4 corresponds to the opening on the side of the support cartridge 2, and then the impurities in the filter cartridge 4 can slide into the filter box 1, and then the drive motor 7 is rotated in the opposite direction, so that the openings of the filter cartridge 4 and the support cartridge 2 are misaligned again;

[0030] The impurities in the sewage are discharged secondary to the filter cylinder 4 and the filter plate 8 respectively. When the electric hydraulic push rod 13 is working, the electric hydraulic push rod 13 drives the squeezing plate 9 to squeeze the impurities through the connecting rod 11 and the fixed rod 10, so that the sewage in the impurities can be squeezed out, which is convenient for the staff to collect.
