When the swing piston 38 on the upper left side moves to the right side and abuts against the right side wall of the swing piston cavity 32 on the upper right side, the PLC controls the air pump on the upper left side and the air pump on the lower right side to pump air, and simultaneously controls the air pump on the upper right side and the air pump on the lower left side to pump air, so that the filter cloths 13 incline to the left by taking the rotating ball 12 on the upper side as the center.

The filter cloth 13 is reciprocated in this manner, and the filter cake on the upper side of the filter cloth 13 is shaken off.

It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the invention. All falling within the scope of protection of the present invention. The protection scheme of the invention is subject to the appended claims.
