[0006] A further technical solution is that the cleaning brush is flexibly connected to the rotary sweeper.

[0007] A further technical solution is that a rotating disk is provided in the middle of the rotating sweeper, the rotating disk is fixed to the rotating shaft, a plurality of lifting rings are provided around the rotating disk, and a ring buckle is provided on the cleaning brush, and the ring buckle is connected to the lifting ring.

[0008] A further technical solution is that the top of the rotating disk is a convex structure.

[0009] A further technical solution is that the driving device is a motor, the motor is fixed on the top of the upper cover, and the output shaft of the motor is coaxially fixed with the rotating shaft.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] A tower cleaning device is arranged inside the filter element, a rotating shaft in the tower cleaning device is rotatably connected to the outer shell, a plurality of rotating cleaners are arranged on the rotating shaft, a cleaning brush which can contact the inner wall of the filter element is arranged on the rotating cleaner, and the driving device is used to drive the rotating shaft to rotate, thereby driving the rotating cleaner to rotate. During the process, the cleaning brush can clean up the debris on the inner wall of the filter element. Compared with the prior art, this cleaning method does not need to rely on the buoyancy of water. The cleaning brush has the effect of impacting and cleaning the debris on the filter screen when rotating, so that instant cleaning can be achieved, thereby realizing the automatic cleaning of the filter screen with short cleaning time, good effect, strong continuity and high cleaning efficiency.

[0012] The cleaning brush and the rotary sweeper are movably connected. During the cleaning process, the debris is impacted due to the centrifugal force. Compared with the method of fixing the cleaning brush on the rotating shaft, this type of connection can increase the area of ​​the filtrate passing through the inside of the filter, allowing the filtrate to flow through the filter quickly, thereby improving the filtration efficiency.

[0020] When in use, connect the liquid inlet 12 of the filter to the inlet of the raw liquid pipeline, connect the liquid outlet 10 to the outlet of the pipeline, and connect the sewage outlet 8 to the waste liquid pipeline. According to the actual experience of cleaning the filter screen in the past, the operating frequency of the motor 1 is set. When the motor 1 starts to run, it drives the tower cleaning device 7 to start rotating, and the position relationship between the lifting ring 17 and the cleaning brush 16 is as shown in the figure. Figure 4 As shown, the outer surface of the cleaning brush 16 contacts the filter element 6 to clean the filter element 6. The cleaning brush 16 cleans the filter element 6 in layers, so that the debris can fall smoothly to the sewage outlet 8. Bearings 13 are fixed at both ends of the rotating shaft 14, and the rotating cleaner 15 is evenly staggered in the middle according to the length of the filter element 6. The adjacent rotating cleaners 15 can be staggered at 60° and 90° to facilitate the falling of the cleaned debris. The upper cover 3 is sealed and fixed by the fixing bolts 2 on the upper part of the outer shell 11. The bearing 13 of the tower cleaning device 7 is fixed on the upper cover 3, and the motor 1 is installed on the upper cover 3. The lower end of the outer shell 11 is provided with a sewage outlet 8, and the ball valve 9 is fixed by a thread. By controlling the opening of the ball valve 9, the impurities after cleaning can be removed, and the timing and automatic sewage discharge can be realized. The type of cleaning brush 16 can be selected according to the properties of the filtrate and the characteristics of the main debris. The cleaning brush 16 can use a nylon brush, a wire brush, a hair brush, a cotton brush, etc. according to the on-site conditions.
