Abstract

This utility model relates to the field of sludge treatment technology and discloses a pollution control sludge dewatering machine, including a screw conveyor frame, a main board at its left end, a sludge screw conveying mechanism on its surface, a sludge leveling treatment mechanism and a sludge dewatering and filtration mechanism on the main board surface. The sludge dewatering and filtration mechanism uses a first hydraulic cylinder and a first hydraulic telescopic column to lower the filter press limit frame to limit the sludge, and then a second hydraulic cylinder and a second hydraulic telescopic column drive the filter press plate to press and filter. Water is filtered through the filter belt and sent to the wastewater recovery box. The sludge screw conveying mechanism uses a main control servo motor to drive the auger conveyor shaft. A dosing nozzle can spray flocculant to promote sludge sedimentation. The sludge leveling treatment mechanism uses a pre-leveling scraper and a leveling roller to level the sludge. Compared with the prior art, this sludge dewatering machine has a better filtration effect and higher efficiency, can shorten the agent mixing time, has a compact structure, is environmentally friendly, and effectively solves the problems of low dewatering efficiency and easy clogging of filter cloth in traditional equipment.
