[0026] The bottom end of the inner wall of the filter cartridge 31 is designed to be an inclined surface, and a cleaning pipe 33 is connected to the lowest side position of the outer side of the filter cartridge 31.

[0027] A sealing rubber ring 36 is connected to the top of the filter cartridge 31 , and the sealing rubber ring 36 is embedded in the water inlet bin 11 through a sealing groove, and the filter cartridge 31 and the water inlet bin 11 are fixed by bolts.

[0028] The vibration assembly 4 includes a screen 44, a vibrator 45 is installed on the side of the top end of the screen 44, and the bottom end of the screen 44 is in a curved structure.

The bottom end of the return spring 42 is connected and fixed to a fixed ring frame 41 , and the fixed ring frame 41 is connected and fixed to the inner wall of the filter cartridge 31 .

[0030] The top cover 21 is buckled on the top of the water inlet bin 11, so that the water inlet bin 11 can be closed. The water inlet pipe 22 can be conveniently connected to the sewage pipe, so that the sewage can be directly flushed into the water inlet bin 11. The guide plate 23 is designed to guide the sewage entering from the water inlet pipe 22, so that the sewage can be collected centrally, and the water flow can flow and impact between the two crushing rollers 12, so that the sundries in the sewage can be crushed conveniently. The inclined surface design of the filter cartridge 31 allows the sludge to be flushed through the cleaning pipe 33 after it is precipitated inside the filter cartridge 31. The sludge can be guided by the inclined surface of the filter cartridge 31 so that the sludge can flow out with the flushing water through the cleaning pipe 33, thereby improving the filter cartridge 31. 1. Convenience of internal cleaning. When the filter cartridge 31 and the water inlet bin 11 are connected by bolts, the sealing rubber ring 36 can be embedded in the sealing groove of the water inlet bin 11 to ensure the sealing performance of the connection between the water inlet bin 11 and the filter cartridge 31.

[0031] Working principle: According to the attached Figure 1 With attached Figure 2As shown, when sewage enters from the water inlet pipe 22, the guide plate 23 can guide the sewage so that the sewage carrying debris can fall between the two crushing rollers 12. At this time, the drive motor 14 is started, and the output end of the drive motor 14 can drive the gear 13 to rotate. The two gears 13 are meshed with each other through the teeth, which can drive the two crushing rollers 12 to rotate relative to each other, thereby facilitating the crushing of the debris. The crushed debris passes through the water inlet bin 11 under the impact of the sewage and enters the interior of the filter bucket 35. The debris can be preliminarily intercepted by the filter bucket 35.

[0032] Secondly, according to the attached Figure 3 and attached Figure 4 As shown, when the sewage after the initial filtration impacts the surface of the screen 44, it is filtered for the second time by the screen 44, and at the same time, the vibrator 45 is started, and the vibrator 45 can drive the screen 44 to vibrate, so that the screen 44 filters the debris during the vibration, and prevents the debris from sticking to and clogging the pores of the screen 44, thereby ensuring the filtering effect of the debris in the sewage. When the sewage is precipitated inside the filter cartridge 31, the sludge can be accumulated at the bottom end of the inner wall of the filter cartridge 31, and at the same time, the cleaning pipe 33 can be opened to allow the water flow to be discharged from the solenoid valve drain pipe 32. After the sewage is discharged, the cleaning pipe 33 can be opened to clean the accumulated sludge.
