When in use, the collected rainwater and other reclaimed water are transported to the inside of the filter box 1 through the inlet pipe 3 and filtered through the two layers of filter screens 2, and then discharged from the outlet pipe 4 to the storage device for storage. When the filter screen 2 inside the filter box 1 needs to be cleaned, the impurities filtered out of the filter screen 2 can be pushed out of the filter box 1 for collection through the cleaning mechanism, and the cleaning work of the filter screen 2 is automatically completed, which has better practicality and is more convenient for promotion and use. At the same time, when the cleaning mechanism cleans the filtered impurities, the flushing mechanism can spray water on the filter screen 2 at a certain water pressure to flush it, so as to dredge the mesh blocked by the filter screen 2, improve the cleaning effect of the filter screen 2, and further improve the practicality of the device.

[0032] It should be noted that the control method of the present application is controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present application is mainly used to protect mechanical devices, so the present application will no longer explain the control method and circuit connection in detail.

[0033] In this embodiment, four supporting columns are fixed to the bottom surface of the filter box 1. The filter box 1 is a rectangular empty warehouse. Control valves are fixed on the outer peripheral walls of the water inlet pipe 3 and the water outlet pipe 4. The water outlet pipe 4 is a three-way pipe, and one end of it is connected to the water storage device and the other end is connected to the sewage pipe. It should be understood that when the filter box 1 is used to filter grey water, the control valve at the end connected to the water storage device is opened, and the control valve at the end connected to the sewage pipe is closed. When cleaning the filter screen plate 2, the control valve at the end connected to the water storage device is closed, and the control valve at the end connected to the sewage pipe is opened. Two glass observation windows are fixed on the front of the filter box 1. The two filter screen plates 2 are distributed up and down, and the mesh diameter of the top filter screen plate 2 is larger than the mesh diameter of the bottom filter screen plate 2.

Two drainage holes 508 are provided on the right side of the filter box 1. When it is necessary to clean the filter screen plate 2, stop supplying the middle water to the inside of the filter box 1, and then start Cylinder 501, cylinder 501 pushes the connecting plate 502 to move to the right, and the connecting plate 502 drives the sealing plates 504 on its upper and lower sides to move to the right through the connecting rod 503 and no longer blocks the drain hole 508. When the two sealing plates 504 move to the right synchronously, they will also drive the guide rod 505 to move to the right, and then drive the two scrapers 506 inside the filter box 1 to move to the right, and push the impurities on the filter screen plate 2 to the right out of the drain hole 508 and drop them into the collection box 507 for collection. After cleaning is completed, retract the cylinder 501 to drive the sealing plate 504 to move to the left to seal the drain hole 508.

[0039] The working principle of the above embodiment is:

[0040] (1) When it is necessary to clean the filter screen plate 2, stop supplying grey water to the inside of the filter box 1, and then start the cylinder 501. The cylinder 501 pushes the connecting plate 502 to move to the right. The connecting plate 502 drives the sealing plates 504 on its upper and lower sides to move to the right through the connecting rod 503 and no longer blocks the drain hole 508. When the two sealing plates 504 move to the right synchronously, they also drive the guide rod 505 to move to the right, and then drive the two scrapers 506 inside the filter box 1 to move to the right, and push the impurities on the filter screen plate 2 to the right out of the drain hole 508 and drop them into the collection box 507 for collection. After cleaning is completed, retract the cylinder 501 to drive the sealing plate 504 to move to the left to seal the drain hole 508.

[0041] (2) When the cleaning mechanism drives the scraper 506 to move rightward to clean and filter impurities, the scraper 506 will also drive the flushing chamber 604 to move rightward. During the movement, the water pump 602 is started, and the water pump 602 draws out the water inside the water tank 601 and delivers it into the water supply pipe 603 at a certain water pressure. The water is further delivered to the flushing chamber 604 through the water supply pipe 603 and the connecting pipe 605, and is sprayed onto the filter screen plate 2 through the flushing hole 606 on the bottom surface of the flushing chamber 604 to flush it.
