[0015] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0016] Please see Figure 1-4 As shown in the figure, an automatic cleaning and filtration device for wastewater treatment according to this application includes a filter box 1 and a cylindrical filter body 11 rotatably connected inside the filter box 1. The surface of the cylindrical filter body 11 is provided with a filter layer 101. Specifically, a cleaning base 12 is also provided inside the filter box 1. The cleaning base 12 is located on one side of the cylindrical filter body 11 and is arranged along the axial direction of the cylindrical filter body 11. A plurality of spray holes 122 arranged in an array are opened on the side of the cleaning base 12 facing the cylindrical filter body 11 for spraying water to rinse the cylindrical filter body 11. The side of the cleaning base 12 facing the cylindrical filter body 11 is also covered with soft bristles 121, and the bristles have a contact surface that contacts the surface of the cylindrical filter body 11.

[0017] Furthermore, a high-pressure nozzle (not shown in the figure) is installed inside the nozzle 122, and the high-pressure nozzle (not shown in the figure) is connected to the water supply pipe 2.

[0018] Furthermore, the filter housing 1 is also provided with a transmission mechanism 3 for driving the cylindrical filter body 11 to rotate. The transmission mechanism 3 includes a mounting plate 31 fixedly connected to the top of the filter housing 1 and a main transmission wheel 33 sleeved on the center of the cylindrical filter body 11. A drive motor 32 is mounted on the mounting plate 31, and a secondary transmission wheel 34 is fixedly connected to the power end of the drive motor 32. A transmission belt 35 is tensioned between the main transmission wheel 33 and the secondary transmission wheel 34.

[0019] In another embodiment of the present invention, the cleaning base 12 includes a support 1201, a first cleaning block 1202 and a second cleaning block 1203 fixedly connected to the support 1201. The second cleaning block 1203 is located below the first cleaning block 1202. The side of the first cleaning block 1202 facing the cylindrical filter body 11 is covered with soft bristles 121. The side of the second cleaning block 1203 facing the cylindrical filter body 11 is provided with a plurality of spray holes 122 arranged in an array.

[0020] Furthermore, a differential pressure sensor is also connected to the cylindrical filter body 11 to monitor the pressure difference between the inside and outside of the filter layer 101.

[0021] The working principle of this application is as follows: When the differential pressure sensor detects that the pressure difference between the inside and outside of the cylindrical filter body 11 exceeds the preset threshold, the control system synchronously starts the transmission mechanism 3 to drive the cylindrical filter body 11 to rotate. Through the rotation of the cylindrical filter body 11, while the cleaning base 12 remains stationary, the simplified design enables full contact with the soft bristles 121 to clean the dirt. The dirt brushed out can also be rinsed back through the array of nozzles, improving the cleaning efficiency.

[0022] In summary, the present application has a simple structure. By setting a cleaning base 12 inside the sewage treatment device, the base is used as a carrier for the cleaning components. The combined effect of high-pressure jet and bristles is used to remove impurities from the surface of the filter cartridge, forming a composite cleaning mode. This not only adapts to pollutants of different viscosities, but also reduces manufacturing costs and improves cleaning efficiency.
