[0027] The screen cleaning mechanism comprises: a protective cover 1 , a support frame 2 arranged in the protective cover 1 , a flushing device 3 for spraying a cleaning medium toward the screen, a blowing device 4 for spraying gas toward the screen, and a moving device 5 arranged on the protective cover 1 .

[0028] The flushing device 3 and the purge device 4 are arranged in the protective cover 1. The flushing device 3 and the purge device 4 are arranged on both sides of the screen. The moving device 5 drives the flushing device 3 and the purge device 4 to move in the same direction. The height of the flushing device 3 spraying the cleaning medium is less than the height of the purge device 4 spraying the gas. The purge device 4 sprays the gas at an angle toward the removal direction of the purge device 4.

[0029] The flushing device 3 is located on one side of the screen and sprays the cleaning medium toward the screen, and the purge device 4 is located on the other side of the screen and sprays the gas toward the screen. Since the flushing device 3 is located lower than the purge device 4, the cleaning medium sprayed by the flushing device 3 first passes through the screen, and the impurities on one side of the screen are washed away, and some impurities on the screen will remain on the other side of the screen. The gas sprayed by the purge device 4 later contacts the cleaning medium, and the cleaning medium completes the flushing of the other side of the screen under the drive of the gas, and at the same time, the gas passes through the screen to complete the blowing and drying treatment of the screen.

[0030] The moving device 5 drives the flushing device 3 and the blowing device 4 to move simultaneously, and the flushing and drying of the screen are completed during the movement, thereby improving the working efficiency. The flushing device 3 and the blowing device 4 are arranged opposite to each other and are respectively located on both sides of the screen. The flushing device 3 completes flushing from one side of the screen, and the blowing device 4 completes flushing and drying from the other side of the screen using a cleaning medium, thereby achieving flushing of both sides of the screen and avoiding residual impurities on the screen.

[0031] The moving device 5 drives the flushing device 3 and the blowing device 4 to move from top to bottom, and then resets to move horizontally, and then moves from top to bottom again, and the whole screen is cleaned after repeated reciprocation.

[0032] The upper and lower ends of the support frame 2 are respectively provided with mounting grooves 21. The mounting grooves 21 are arranged opposite to each other. The screen is inserted into the mounting grooves 21 to restrict the upper and lower ends of the screen. The upper end of the screen is inserted into the mounting groove 21 at the upper end of the support frame 2, and the lower end of the screen is inserted into the mounting groove 21 at the lower end of the support frame 2.

[0033] Rollers 22 are rotatably arranged in parallel in the mounting groove 21. The rollers 22 can be rotatably arranged in parallel in the mounting groove 21 at the lower end of the support frame 2, and the rollers 22 can also be rotatably arranged in parallel in the mounting groove 21 at the upper end of the support frame 2 and the mounting groove 21 at the lower end of the support frame 2.
