automatic 304 stainless steel spiral sludge dewatering machine high dehydration rate not easy to block
The screw type sludge dehydrator applies the principle of screw extrusion. It is a solid-liquid separation equipment that can squeeze and dewater sludge through the strong extrusion force generated by the change of screw diameter and screw pitch, and the small gap between the movable ring and the fixed ring. It can be widely used in breeding farms, slaughterhouses, sewage treatment, food processing, coal washing and chemical industries, etc. It is an energy-saving and environment-friendly water treatment equipment.
Working Principle
The sludge is delivered to the flocculation mixing device through the sludge inlet pump, and the polymer flocculant is injected into the flocculation mixing tank. The sludge after alum is formed after the reaction of the stirred sludge and the polymer flocculant, and then enters the dehydration part after the gravity concentration of the snails stacking body. The screw pitch of the spiral axis of the dewatering part gradually decreases along the direction of the mud cake discharge outlet, because the compression of the back pressure plate increases the internal pressure in the main body, so as to achieve the purpose of dewatering. After dewatering, it is discharged in the way of mud cake.
Product Features
1. Separation technology: the organic combination of spiral pressure and dynamic and static rings forms a new separation technology integrating concentration and dehydration, which increases the selection of advanced dehydration methods for China's environmental sewage treatment field.
2. Energy saving and water saving: due to the continuous movement of the dynamic and static rings, the self-cleaning effect of the cylinder is achieved, and the filter gap is not easy to be blocked.
3. Double the processing capacity: the processing capacity of the sludge dehydrator is twice that of the previous dehydrators. One unit can solve the sludge volume generated by 10000 tons of sewage, and can be equipped with 50-40% deep sludge dewatering design process. A single set of process can solve 1-3 tons of sewage treatment capacity.
4. The pressure regulating plate of the spiral sludge dehydrator adopts elastic automatic regulation to naturally balance the internal pressure of the sludge in the dewatering section, which can effectively ensure the service life of the dynamic and static ring discs.
5. Green environmental protection: the whole machine is sealed and can be directly observed. The shell is easy to disassemble and assemble, no sewage leakage, no secondary pollution, and the noise is less than 45 decibels, making the sludge room a beautiful environment and civilized production.
6. The spiral sludge dehydrator has no blocking elements such as filter cloth and filter hole, which is safe and simple to operate, and can be determined according to the customer's operation time. Combined with automatic control system, the spiral sludge dehydrator can realize unattended automatic operation through program.
