Stainless steel screw press dewatering machine for sludge treatment introduction
The screw sludge dewatering machine belongs to the screw press and has no clogging, which can reduce the sedimentation tank and the sludge concentration tank, and save the construction cost of the sewage treatment plant.
The machine adopts screw and moving coil to clean the non-blocking structure by itself. It is automatically controlled by PLC. It is a new technology. It can directly concentrate and dehydrate for 24 hours and operate by itself, which greatly reduces the cost of design, construction and operation and maintenance.
Working guidelines
When the machine starts running, the sludge is pushed from the feed port into the filter cartridge and then moved to the sludge cake outlet by the screw shaft blades.
Because the gaps among the helical axis blades will gradually getting narrower,the sludge is undering heavier pressure.Then the water gradually comes out from it as a result of pressure differential and issues from the filtering space between the fixed plates and the moving plates.The self-cleaning function of the fixed plate and the moving plate can be used to avoid clogging.Finally, the sludge cake is pushed by the screw shaft after being completely dehydrated and then discharged from the outlet.
Advantage
Flat moving and fixed rings effectively reduce the wear and tear of ring slice;
Ring slices are assembled in sections, easy to disassemble and maintenance;
Heat-treatment screw shafts can enhance rigidity,and become more wear-resisting;
Mud resist ring and mud resist board, reducing the sludge
Bending mixing vane of flocculation tank makes the medicament mix evenly;
Two-door design electric control panel is waterproof.
The height of flocculation tank overflow can be adjusted.
