Filtering device for treating sludge

The invention relates to the technical field of sludge treatment, in particular to a filtering device for treating sludge. The filtering device for treating sludge comprises a tank body, a material storage body, a rotating shaft, a material scraping mechanism, a cleaning mechanism, a driving mechanism, a plurality of suction filtration pipes, a plurality of filtering mechanisms and two air supply mechanisms. The air supply mechanism is used for sucking or blowing air into the suction filtration pipe. And the scraping mechanism is used for removing the filtered materials from the filter screen. The cleaning mechanism is used for cleaning the device. The driving mechanism drives the rotating shaft to rotate. The invention provides a filtering device for treating sludge, aiming at solving the problems that the existing tank type filter press adsorbs sludge onto a filtering plate through pressure in a tank and adsorption pressure, a filtering net on the filtering plate can be damaged after long-time filtering, an
