When the dirt on the filter cloth begins to flip downward, under the action of gravity, part of the dirt falls into the waste box. Through the two gears, the transmission roller can drive the mounting roller, the bristles and the mounting shaft to rotate in the opposite direction when rotating. The bristles produce friction with the surface of the filter cloth during the rotation process, thereby enabling the filter cloth to be deeply cleaned. At the same time, the rotation of the mounting shaft drives the turntable to rotate. When the arc-shaped protrusion contacts the mounting frame, the mounting frame is forced to move to one side. When the arc-shaped protrusion is separated from the mounting frame, the mounting frame can be reset under the action of the elastic force of the spring, and the mounting frame drives the mounting roller to move, thereby enabling the reciprocating drive of the mounting roller. In summary, the utility model can facilitate the cleaning of the filter cloth, has a good cleaning effect, and will not affect the subsequent filtering work during the cleaning process, and has strong practicality.

It is rotatably installed on the cleaning box 6, and the mounting roller 13 is slidably installed on the mounting shaft 22 along its length direction. A center hole 131 for the mounting shaft 22 to pass through is provided at the inner center of the mounting roller 13, and a key 23 is provided on the inner side of the center hole 131. A key groove 221 for the key 23 to slide is provided on the mounting shaft 22 along its length direction. The bristles 11 are installed on the outer surface of the mounting roller 13, and the two gears 16 are respectively installed on the rotating shaft of the transmission roller 8 and the mounting shaft 22, and the two gears 16 are meshedly connected. The turntable 19 is fixed on the mounting shaft 22, and the arc-shaped protrusion 20 is fixed on the turntable 19.

[0030] The waste box 4 is arranged below the conveying end of the filter cloth 2 , and a scraper 21 is arranged adjacent to the conveying end of the filter cloth 2 . The scraper 21 is mounted on the frame 1 , and the dirt on the surface of the filter cloth 2 can be scraped off by the scraper 21 .
