[0024] A first filter plate 210 is fixedly installed at the upper end of the first filter chamber 25, and the first filter plate 210 is inclined towards the lower front side; a first discharge port 211 communicating with the first filter chamber 25 is provided on the front surface of the filter box 21 relative to the first filter plate 210; a first slag collection box 212 communicating with the first discharge port 211 is fixedly installed on the front side of the filter box 21 relative to the first filter chamber 25; the first filter chamber 25 is connected to the stirring chamber 26 through a first water supply pipe 213; a stirring rod 214 is rotatably installed in the stirring chamber 26, and the upper end of the stirring rod 214 extends through the filter box 21 to the outside of the filter box 21, and is fixedly connected to the rotating output shaft of the stirring motor 215 fixedly installed at the upper end of the filter box 21; the stirring motor 215 also has a... A reagent dispenser 216 is provided; a stirring chamber 26 is connected to the upper end of a second filter chamber 27 via a second water supply pipe 217; a second filter plate 218 is fixedly installed at the upper end of the second filter chamber 27, and the second filter plate 218 is inclined towards the lower front side; a second discharge port 219 connected to the second filter chamber 27 is provided on the front surface of the filter box 21 relative to the second filter plate 218; a second slag collection box 220 connected to the second discharge port 219 is fixedly installed on the front side of the filter box 21 relative to the second filter chamber 27; a connecting groove connecting the second filter chamber 27 and the third filter chamber 28 is provided at the lower end of a partition 24 between the second filter chamber 27 and the third filter chamber 28; a depth filtration device 221 is also fixedly installed inside the third filter chamber 28.

[0025] The deep filtration device 221 includes a support 2211, a flat sheet membrane 2212, an aeration pipe 2213, an air supply pipe 2214, and a purified water collection pipe 2215. The support 2211 is fixedly installed in the third filtration chamber 28. The flat sheet membrane 2212 is fixedly connected to the support 2211 through a slot provided on the support 2211. The aeration pipe 2213 is located at the lower end of the flat sheet membrane 2212 and is fixedly connected to the support 2211. The air supply pipe 2214 is located on one side of the support 2211 and communicates with the aeration pipe 2213. The purified water collection pipe 2215 is located above the flat sheet membrane 2212 and is connected to the outlet of the flat sheet membrane 2212. The purified water collection pipe 2215 extends through into the purified water chamber 29.

[0026] Working principle:

[0027] First, the water to be treated is discharged through the outlet of the cleaning device 1 and enters the inlet 22 of the filter device 2 through the drain pipe 3. The water first enters the first filter chamber 25, where it is initially filtered by the first filter plate 210. Large particles of sand and impurities are trapped on the first filter plate 210. Since the first filter plate 210 is inclined to the lower front side and cooperates with the first discharge port 211 and the first slag collection box 212 on the front side of the filter box 21, the filtered sand and impurities are discharged into the first slag collection box 212, which facilitates the periodic cleaning of accumulated impurities.

[0028] After preliminary filtration, the water enters the mixing chamber 26 through the first water supply pipe 213. The inlet end of the first water supply pipe 213 is cleverly located at the upper end of the first filter chamber 25 and the lower side of the first filter plate 210, and is equipped with a filter screen to prevent impurities deposited at the bottom from being carried into the mixing chamber 26. Inside the mixing chamber 26, the stirring motor 215 drives the stirring rod 214 to rotate and stir the water. At the same time, the chemical dosing device 216 adds flocculants and disinfectants to the water as needed. The stirring rod 214 fully mixes the flocculants and disinfectants with the water. The flocculants coagulate and precipitate the sewage, allowing the suspended particles in the sewage that are difficult to settle to aggregate with each other, and then combine with impurities in the water to form larger flocs that adsorb bacteria, dissolved substances and heavy metals to improve the subsequent filtration effect.

[0029] The stirred water enters the second filter chamber 27 through the second water supply pipe 217. The inlet end of the second water supply pipe 217 is located at the bottom of the stirring chamber 26, and the outlet end is located at the upper end of the second filter chamber 27, above the second filter plate 218. Wastewater is transported to the second filter plate 218 for further filtration. The second filter plate 218 also adopts an inclined design and cooperates with the second discharge port 219 and the second slag collection box 220, so that the filtered impurities are discharged into the second slag collection box 220 for easy periodic cleaning of accumulated impurities.

[0030] Water filtered by the second filter plate 218 enters the third filter chamber 28, which is connected to the second filter chamber 27 through a connecting groove. In the third filter chamber 28, the deep filtration device 221 performs the final purification treatment on the water. The device includes a support 2211, a flat sheet membrane 2212, an aeration pipe 2213, an air supply pipe 2214, and a purified water collection pipe 2215. The flat sheet membrane 2212 is fixed by the support 2211 and effectively removes suspended solids, bacteria, and other impurities from the water by utilizing the high retention rate of microfiltration or ultra-microfiltration membranes, thereby reducing the organic matter content of the effluent. The aeration pipe 2213 is located below the flat sheet membrane 2212 and supplies gas through the air supply pipe 2214. The gas forms small bubbles on the aeration pipe 2213, which impact the surface of the flat sheet membrane 2212 to prevent sludge particles from accumulating and maintain filtration efficiency. Finally, the purified water treated by the deep filtration device 221 is collected through the purified water collection pipe 2215 and transported to the purified water chamber 29. Finally, it is returned to the cleaning device 1 through the return water pipe 4, forming a closed loop. At the same time, the drain port at the bottom of the first filtration chamber 25 and the inclined surface design on both sides help to concentrate and clean the dirt, ensuring the continuous and efficient operation of the system.

[0031] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0032] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
