[0037] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 A driving assembly 16 is provided between the hollow shaft 4 and the processing box 5. The driving assembly 16 includes a driving motor 1604. The driving motor 1604 is installed at the left end of the top of the processing box 5. A driving shaft 1603 is installed at the power output end of the driving motor 1604. A driving gear 1602 is installed at the top of the driving shaft 1603. The right end of the driving gear 1602 is meshed and connected with a driven gear 1601. The driven gear 1601 is fixedly sleeved on the outer side of the hollow shaft 4. When the driving motor 1604 is working, the driving gear 1602 is driven to rotate through the driving shaft 1603. The rotation of the driving gear 1602 drives the driven gear 1601 to rotate, thereby driving the hollow shaft 4 to rotate.

[0038] Working principle: When the device is used, an external power source is connected, and wastewater enters the interior of the treatment box 5 through the water inlet pipe 2, and the agent is added into the interior of the treatment box 5 through the dosing port 1, and then the drive motor 1604 is started. When the drive motor 1604 is working, the driving gear 1602 is driven to rotate through the driving shaft 1603, and the driving gear 1602 rotates to drive the driven gear 1601 to rotate, and the driven gear 1601 rotates to drive the hollow shaft 4 to rotate, and the hollow shaft 4 rotates to drive the stirring rod 3 to rotate, so that the wastewater and the agent are stirred and mixed, so that the impurities in the wastewater form precipitates and condensates, and the precipitates and condensates in the wastewater are filtered and intercepted by the filter net 8.

[0039] Then open the solenoid valve 12 to discharge the filtered water out of the treatment box 5 through the drain pipe 14. When all the filtered water is discharged, the staff pulls up the handle 2001, and the handle 2001 drives the T-shaped limit rod 2005 to move upward through the movable rod 2002 and squeezes the positioning spring 2004 until the T-shaped limit rod 2005 is separated from the limit groove 2006, thereby releasing the fixing effect of the T-shaped limit rod 2005 on the baffle 1801. Then the staff holds the handle 1802 and pulls it to the left. The handle 1802 drives the baffle 1801 to move to the left, so that the plug 1803 is separated from the inside of the sewage outlet 7.

[0040] At this time, start the water pump 1504. When the water pump 1504 is working, it draws clean water from the water tank 1501 through the suction pipe 1503, and transports the clean water to the inside of the distribution pipe 6 through the hollow shaft 4 through the water pipe 1505. Finally, the clean water is sprayed out through the nozzle 21 to rinse the dirt on the filter screen 8. The dirt is rinsed and moved by the high-pressure water flow. Due to the effect of gravity, the dirt flows through the sewage outlet 7 to the inside of the collection frame 901 for unified collection. After the dirt is cleaned, pull the collection frame 901 outward, and the collection frame 901 drives the slider 902 to move outward until the slider 902 is separated from the slide groove 903, so as to facilitate the disassembly of the collection frame 901 and remove the sediment inside.
