[0028] The cleaning part 32 includes a plurality of stirring rods 321, and a brush 322 is provided at the free end of the stirring rod 321. The brush 322 is closely attached to the inner wall of the filter cartridge 2, so as to effectively clean the residue remaining on the filter hole 21. At the same time, the bottom end of the processing box 1 is open, and the processing box 1 is also provided with a disassembly component 4 to facilitate the disassembly of the filter cartridge 2 and the cleaning part 32. The disassembly component 4 includes a threaded cover 41 and a limiting part 42. The threaded cover 41 is threadedly connected to the lower part of the outer wall of the processing box 1, and the bottom of the filter cartridge 2 is connected to the threaded cover 41. The limiting part 42 includes a limiting plate 421 and two limiting rods 423. One end of the two limiting rods 423 passes through the top of the processing box 1 and extends to the inside of the filter cartridge 2 and is fixedly connected to the limiting plate 421. A limiting spring 422 is sleeved on the outer wall of the limiting rod 423 between the top surface of the limiting plate 421 and the top inner surface of the filter cartridge 2. The center of the limiting plate 421 is rotatably connected to one end of the screw rod 312. The other ends of the two limiting rods 423 are connected to the transmission part 43 to limit the position of the limiting part 42.

[0029] The transmission part 43 includes a rotating rod 431, which is rotatably connected to the top of the motor 311 housing. A gear 432 is sleeved on the outer surface of the rotating rod 431.

[0030] In addition, the other end of the sleeve 313 is threadedly connected to one end of the fixed rod 314, and the fixed rod 314 contacts the top of the threaded cover 41, thereby reducing the shear force on the inserted rod 435 in the transmission part 43; a handle 4311 is provided on the top of the rotating rod 431, thereby improving the convenience of rotating the rotating rod 431; a plurality of stirring rods 321 are evenly fixed to the outer wall of the sleeve 313 along the axial direction of the sleeve 313; a valve 121 is provided on the water outlet pipe 12 for controlling the opening and closing of the water outlet pipe 12.

[0031] The utility model provides an environmentally friendly sewage filtering device. When filtering, sewage is introduced into a treatment box 1 from an inlet pipe 11, and water passes through filter holes 21 on a filter cartridge 2 and is discharged through an outlet pipe 12; some impurities are accumulated at the filter holes 21 on the filter cartridge 2.

[0032] At this time, the motor 311 is started to drive the screw 312 and the sleeve 313 to rotate, and the stirring rod 321 on the outer surface of the sleeve 313 drives the brush 322 to clean the impurities accumulated in the filter hole 21, thereby avoiding the clogging of the filter hole 21 caused by long-term operation.

[0033] After a period of operation, the sewage filter device needs to be disassembled and cleaned. At this time, stop feeding sewage and turn off the motor 311, rotate the threaded cover 41 to separate it from the bottom of the treatment box 1. Since the filter cartridge 2 is fixed with the threaded cover 41, the filter cartridge 2 is disassembled together with the threaded cover 41, and the filter cartridge 2 can be cleaned. In addition, the rotating handle 4311 is rotated to drive the gear 432 on the rotating rod 431 to rotate. Since the gear 432 is meshed with the rack 433, the rack 433 moves outward horizontally, thereby driving the plug rod 435 connected to the end of the rack 433 to be pulled out from the horizontal jack on the limit rod 423. At this time, the elastic force of the limit spring 422 and the gravity of the cleaning component 3 make the cleaning component 3 move downward, and the staff can easily disassemble the cleaning component 3 from the treatment box 1 for cleaning. After all are cleaned, they can be installed in the reverse direction.

[0034] The cleaning assembly 3 is installed in the filter cartridge 2, and the stirring rod 321 and the brush 322 on the outer wall of the sleeve 313 are driven to rotate by the motor 311 and the screw 312 to clean the impurities remaining on the filter hole 21, thereby avoiding the situation that the filter hole 21 is easily clogged by impurities due to long-term filtration and the filtration efficiency is reduced; the threaded cover 41 is fixed together with the filter cartridge 2, and the threaded connection between the threaded cover 41 and the treatment box 1 is used to improve the convenience of disassembly and cleaning of the filter cartridge 2; at the same time, by utilizing the connection between the limit part 42 and the screw 312 and the transmission part 43 limiting the position of the limit part 42, the rotating handle 4311 in the transmission part 43 only needs to be rotated to pull the insertion rod 435 out of the horizontal insertion hole of the limit rod 423, so that the cleaning assembly 3 can be disassembled, which effectively improves the convenience of disassembly and cleaning of the cleaning assembly 3.

[0035] In summary, the device effectively solves the problems of long-term filtration in existing filtration devices, impurities easily clogging the filter plate resulting in reduced filtration efficiency, and a large workload during disassembly and cleaning.
