[0038] A filter box 5 is in communication with the water outlet pipe 23 at the upper portion, and the inside of the filter box 5 is provided with a first filter plate 51, the two sides of the first filter plate 51 in the X direction are provided with openings 52, and the lower portion of the side wall of the filter box 5 is provided with a drain pipe 53;

[0039] An impurity treatment box 6 is in communication with the filter box 5 through the opening 52;

[0040] A scraper 7 is arranged above the first filter plate 51, the bottom of the scraper 7 is in contact with the upper part of the first filter plate 51, and the scraper 7 is movably connected to the filter box 5 along the X direction or the reverse direction of the X direction;

[0041] A transmission device 8 is arranged to drive the scraper 7 to move by the driving motor 4.

[0042] In the above embodiment, sewage enters the purification box 2 through the water inlet pipe 21, the flocculating agent enters the feed pipe 22, and then the driving motor 4 is started to drive the stirring shaft 3 to rotate, so that the flocculating agent is fully mixed with the sewage, improving the sewage purification efficiency. After mixing, the sewage enters the filter box 5 through the water outlet pipe 23, and the impurities are retained on the first filter plate 51. The driving motor 4 drives the scraper 7 to move along the X direction through the transmission device 8. After a period of time, the driving motor 4 is reversed to drive the scraper 7 to move along the reverse direction of the X direction, so that the impurities on the first filter plate 51 are scraped off and fall into the impurity box on both sides of the filter box 5. Compared with the prior art, the filter screen can be cleaned without stopping, thereby improving the efficiency of sewage purification.

[0043] As an optional embodiment, the transmission device 8 includes a rotating shaft 81, a first pulley 82, a second pulley 83, a first bevel gear 84, a second bevel gear 85, and a lead screw shaft 86. The lead screw shaft 86 is connected to the filter box 5 and located above the first filter plate 51. The axial direction of the lead screw shaft 86 is the X direction.

[0044] In the above embodiment, the driving motor 4 is started to drive the second pulley 83 through the first pulley 82, so that the rotating shaft 81 is driven to rotate. The rotating shaft 81 drives the first bevel gear 84 to rotate, and the first bevel gear 84 drives the second bevel gear 85 to rotate. The second bevel gear 85 drives the lead screw shaft 86 to rotate, so that the scraper 7 can move along the X direction or the reverse direction of the X direction. The impurities on a filter plate can be cleaned without stopping.

[0046] In the above implementation, in order to avoid that a small part of sewage falls into the impurity treatment box 6 without passing through the first filter plate 51, the second filter plate 61 is arranged, so that a small part of sewage can pass through the second filter plate 61 and then flow back to the filter box 5 through the drain port 63.

[0047] As an optional implementation, the sidewall of the impurity treatment box 6 is provided with a pull-out port 64, and the impurity treatment box is movably connected to the pull-out port 64.

[0050] In the above implementation, the radius of the first belt pulley 82 can be arranged to be smaller than the radius of the second belt pulley 83, so that a speed reducer can be formed, the speed of the rotating shaft 81 is slow, and the scraper 7 can move slowly in the X direction or in the reverse direction of the X direction, and the first filter plate 51 can be better cleaned.

[0051] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent transformation or direct or indirect application in the related technical field is also included in the patent protection range of the present application.
