Technical Field

[0001] The utility model relates to the technical field of sludge dewatering machines, in particular to a pressure filtering type sludge dewatering machine. Background Art

[0002] A large amount of sludge will be produced after sedimentation treatment of sewage. Even after concentration and digestion treatment, the water content is still as high as 96%. The volume is very large and difficult to dispose of. It must be dehydrated to increase the solid content of the mud cake to reduce the area occupied by sludge stacking.

[0003] A pressure filtering sludge dewatering machine is a device used to treat sludge. Its main function is to remove water from the sludge, thereby reducing the volume, increasing the solid content, and facilitating subsequent treatment or disposal. The main way for a pressure filtering sludge dewatering machine to dewater sludge is to use mechanical parts to physically squeeze the sludge to remove the water from the sludge. If too much sludge is added to the sludge dewatering machine at one time, it is easy to exceed the use capacity of the spiral blades used to squeeze the sludge and thus be damaged. The existing sludge dewatering machine is not convenient for quantitative and uniform sludge feeding. The water removed from the sludge by the sludge dewatering machine often contains pollutants and needs to be filtered with a filter pad before discharge. The filter pad needs to be replaced in time after long-term use. The existing sludge dewatering machine is not convenient for replacing the filter pad. For this reason, a pressure filtering sludge dewatering machine is proposed. Utility Model Content
