The outer side of the drain outlet 3 and the sealing door 31 are threaded together. A handle is fixedly installed on the outer side of the sealing door 31. By unscrewing the sealing door 31 with the handle, the motor 21 drives the spiral blade 2 to rotate, which drives the sludge in the settling chamber 1 to be automatically discharged from the drain outlet 3, thereby cleaning and discharging sludge from the settling chamber 1.

[0025] Please see Figures 1-4 The left side of the filter chamber 4 and the upper right side of the settling chamber 1 are connected to each other. The filter plate 5 and the inner side of the filter chamber 4 are slidably connected through a slot. The front side of the filter plate 5 and the sealing cover 6 are fixedly connected. The sealing cover 6 and the filter chamber 4 are sealed together. The surface of the sealing cover 6 and the filter chamber 4 are detachably connected by bolts. In this embodiment, the lower end of the scraper 7 and the surface of the filter plate 5 are in contact with each other. The lead screw 8 and the scraper 7 are threaded together. A second motor 81 is fixedly installed on the right side of the filter chamber 4. The output end of the second motor 81 extends to the filter chamber 4.

The upper end of the dosing hopper 12 is equipped with a hopper cover. Wastewater is injected into the sedimentation chamber 1 through the inlet valve for sedimentation. After sedimentation, the water level rises to enter the filter chamber 4. After the remaining impurities are removed by the filter plate 5, the wastewater enters the dosing chamber 10. Wastewater treatment agent is added into the dosing chamber 10 through the dosing hopper 12. The stirring roller 11 is driven by the motor 3111 to rotate, so as to fully mix the treatment agent and wastewater. Then it is discharged from the drain valve to achieve the treatment of wastewater.

[0027] During operation, wastewater is injected into settling chamber 1 through the inlet valve for sedimentation. After sedimentation, the water level rises to enter filter chamber 4. After passing through filter plate 5 to remove remaining impurities, the wastewater enters dosing chamber 10. Wastewater treatment agent is added to dosing chamber 10 through dosing hopper 12. Motor 3111 drives the stirring roller 11 to rotate, thoroughly mixing the treatment agent and wastewater. The mixture is then discharged through the drain valve, thus treating the wastewater. After a period of use, the sludge inside settling chamber 1 and on the surface of filter plate 5 needs to be cleaned using motor 8. 1. Control the screw 8 to rotate, so that the scraper 7 scrapes across the surface of the filter plate 5 along the slide rod 9, thereby automatically cleaning the filter plate 5. Afterwards, the bolts on the surface of the sealing cover 6 can be removed to loosen the fixing of the sealing cover 6, making it convenient to remove the filter plate 5 for more detailed cleaning and maintenance or replacement. The scraper 7 pushes the sludge on the surface of the filter plate 5 into the settling chamber 1. By unscrewing the handle to open the sealing door 31, the motor 21 drives the spiral blade 2 to rotate, which drives the sludge in the settling chamber 1 to be automatically discharged from the drain port 3, thereby cleaning and discharging the sludge in the settling chamber 1, which is convenient and quick.

[0028] Through the above steps, the screw 8 is rotated by the motor 2 81, causing the scraper 7 to scrape across the surface of the filter plate 5 along the slide rod 9, thereby achieving automatic cleaning of the filter plate 5. The scraper 7 pushes the sludge on the surface of the filter plate 5 into the settling chamber 1. By unscrewing the handle to open the sealing door 31, the motor 21 drives the spiral blade 2 to rotate, causing the sludge in the settling chamber 1 to be automatically discharged from the drain outlet 3. This solves the problem that impurities settled and filtered by the sewage treatment equipment will accumulate in the device and easily adhere to the inside of the equipment and the surface of the filter screen, resulting in a time-consuming, labor-intensive, and inefficient cleaning process.
