The present invention discloses a hydraulically driven cleaning rotary
screen filter device, comprising a support frame, a driving roller
assembly, a supporting plate, a driven roller
assembly, a filter screen, a water-blocking plate, a connecting
pipe, an automatic driving mechanism and a
sludge removal
assembly, wherein two support frames are symmetrically arranged, the driving roller assembly is arranged between the two support frames, and the automatic driving mechanism comprises a second main shaft, an
impeller, a connecting assembly and a supporting cylinder, and the
impeller is fixedly inserted on the outside of the second main shaft. The present invention utilizes a setting mode in which the filter screen and the automatic driving mechanism are matched, and the filter screen meshed therewith can be driven to operate by the rotation of the first rotating wheel, and then the
sludge is brushed off onto the
sewage discharge bearing plate by the cleaning
brush, so that the automatic driving mechanism continuously drives the filter screen to operate, and the mud,
dirt and the like on the filter screen are removed in time, the structure is relatively complete, the reliability is high, the operation is simple and reasonable, and the efficiency of cleaning floating objects in the sand
settling tank is significantly improved.
