[0037] Specifically, by starting the servo motor 5, the turntable 12 fixed at the output end can be driven to rotate. When the turntable 12 rotates, the correspondingly connected filter cartridge 11 can be driven to rotate. Subsequently, wastewater is injected into the outer shell 1 through the water inlet pipe 3. The wastewater entering will enter the fixed disk 10 through the water inlet pipe 3. Since the fixed disk 10 is connected to the filter cartridge 11, the wastewater entering the fixed disk 10 will enter the inside of the filter cartridge 11. As the filter cartridge 11 rotates driven by the servo motor 5, the wastewater in the filter cartridge 11 can be turned over, so that the wastewater in the filter cartridge 11 can be fully filtered while effectively preventing the filtered impurities from accumulating at a certain place in the filter cartridge 11 and clogging the filter holes on the filter cartridge 11 to prevent them from affecting the normal filtering effect of the device.

[0038] Reference Figure 1 , Figure 2 or Figure 5 The fixing device 2 includes a fixing block 201. The front and rear fixing blocks 201 are fixedly connected to the front and rear walls of the pull plate 6. The front and rear fixing blocks 201 are rotatably connected to the connecting rod 202 on the side close to the shell 1. The front and rear sides of the middle part of the side wall of the shell 1 are provided with a card slot 206. The inner walls of the front and rear card slots 206 are provided with a circular groove 208. The ends of the front and rear connecting rods 202 away from the fixing block 201 penetrate the card slot 206 and are fixedly connected to the card block 207.

The ends of the front and rear torsion springs 204 away from the fixing ring 203 are fixedly connected to the fixing block 201;

[0039] Specifically, by rotating the knob 205, the connecting rod 202 can be driven to rotate. When the connecting rod 202 rotates, the corresponding fixed block 207 can be driven to rotate. When the block 207 rotates 90 degrees and is parallel to the slot 206, the limit between the block 207 and the circular groove 208 can be cancelled. Then, the pull plate 6 is pulled outward to pull the block 207 out of the slot 206. At the same time, the fixed plate 8 can also be pulled out of the through slot 7. When the fixed plate 8 moves, the turntable 12 can be driven to move, and the through plate 12 can be used to The filter cartridge 11 is pulled out from the inside of the shell 1. When it is to be installed, it only needs to be inserted into the shell 1 and stuck in the support groove 15, and the knob 205 is turned to rotate the block 207, so that it can be stuck in the circular groove 208 through the slot 206.

[0045] Specifically, the knob 205 is provided to facilitate the staff to rotate the connecting rod 202 , and the visual window 4 is provided to facilitate the staff to observe the filtering situation inside the housing 1 .

[0046] Working principle: In actual use, by starting the servo motor 5, the turntable 12 fixed at the output end can be driven to rotate. When the turntable 12 rotates, the filter cartridge 11 can be driven to rotate, and waste water is injected into the housing 1 through the water inlet pipe 3. The waste water entering will enter the interior of the filter cartridge 11 through the fixed disk 10. As the filter cartridge 11 rotates, the waste water in the filter cartridge 11 can be turned over, so as to prevent impurities from clogging the filter holes and affecting the normal filtering effect of the device. In addition, when the filtration is completed and it needs to be cleaned, the connecting rod 202 and the block 207 can be driven to rotate by rotating the knob 205. When the block 207 rotates ninety degrees, the block 207 can be pulled out of the slot 206, and the fixed plate 8 can also be pulled out of the through slot 7. When the fixed plate 8 moves, the turntable 12 and the filter cartridge 11 can be driven to move, and the filter cartridge 11 can be pulled out from the interior of the housing 1, so as to facilitate the cleaning or replacement of the filter cartridge 11.
