[0023] The specific operation is as follows: the driving motor 2 7 drives the transmission roller 8 to rotate, and the transmission roller 8 drives the transmission belt 9 to rotate the filter mesh cylinder 10 and the filter mesh cylinder 2 11, and the brush roller 6 is used to frictionally contact with the filter mesh cylinder 10 and the filter mesh cylinder 2 11 to brush off the impurities attached to their surfaces, so that the filter mesh cylinder 10 and the filter mesh cylinder 2 11 are always in the best working state, thereby improving the filtration efficiency.

[0024] like Figure 1 and Figure 2As shown, a feeding port 2 is provided at the lower right side of the shell 1, and a stirring assembly 3 is installed at the upper right side of the shell 1, the stirring assembly 3 includes a servo motor 301, a positive and negative threaded screw 302 and a screw nut 303, and the output end of the servo motor 301 passes through the right side of the shell 1 and is connected to the positive and negative threaded screw 302, the outside of the positive and negative threaded screw 302 is connected to the screw nut 303, the stirring assembly 3 also includes a support rod 304, a movable seat 305 and a driving motor 306, and the surface of the screw nut 303 is connected to the support rod 304 through a rotating shaft, and the other end of the support rod 304 is connected to the support rod 304 through the rotating shaft A movable seat 305 is connected, and a driving motor 306 is installed at the middle end of the top of the movable seat 305. The stirring assembly 3 also includes a driving rod 307, a scraper 308 and a stirring blade 309, and the output end of the driving motor 306 passes through the movable seat 305 and is connected to the driving rod 307.
