Technical Field

[0001] The utility model relates to the field of filter presses, in particular to a desludging filter press device. Background Art

[0002] Sludge, as an inevitable product of sewage treatment, is formed through a complex and multi-stage biological, physical and chemical process. In the sewage treatment process, since wastewater contains a large amount of suspended solids, organic matter and microorganisms, these substances are degraded and oxidized by microorganisms in a specific biological treatment stage, gradually forming sludge particles.

[0003] The desludging filter press is a key equipment in sludge treatment. Its function is to further remove moisture from the sludge to make it drier. The filter press uses a certain pressure to make the sludge form a filter cake on a specific filter medium, thereby achieving solid-liquid separation.

[0004] The existing desludging filter press device usually uses two filter belts to squeeze the sludge to achieve solid-liquid separation when filtering sludge. It was found in use that the sludge will flow out from the edge of the filter belt when squeezed by the filter belt. This sludge will pollute the device and also reduce the sludge output of the device after filtration.
