Product Details

Product Description
Volute screw sludge dewatering machine which uses the screw extrusion principle is a new type of solid-liquid separation equipment.it reaches the goal extrusion dewatering sludge by the powerful extrusion pressure of changing the screw diameter and distance ,and the tiny spacing between moveable annular plates and fixed annular plates.

Structure Principle
The main body of volute screw sludge dewatering machine is made of multiple fixed annular plates and moveable annular plates with the screw shaft running through it. There are two parts of the body ,thickening department and dewatering department . It can thicken and dewater sludge in one box, and has taken place of the traditional filter clothes and centrifugal filter method for its distinctive filter model.


Dewatering Principle
The wastewater is pushed into the volute screw sludge dewatering machine.The sludge will move to the sludge cake outlet under the pressure of changing the screw diameter and distance.Becuse the gap among the helical blades become narrower,so the sludge bear great pressure.and begain to dewatering under the pressure. The water comes out from the tiny space between fixed and moveable plates.


Product Advantages

1. The unique dehydration principle makes the equipment suitable for high and low concentration sludge, starting from 2000mg / L, creating a precedent for direct dehydration of low concentration sludge.


2.The unique dynamic and static ring filter slot structure makes the equipment not easy to block. There is no need to carry out a lot of cleaning to prevent the filter slot from clogging, completely reducing the flushing water consumption, reducing the internal circulation burden, and solving the troubles caused by the traditional dehydration equipment blockage to the enterprise.


3. The volute screw sludge dewatering machine adopts automatic control from the extraction of sludge, injection of chemical liquid, and discharge of sludge cake. It does not require personnel to operate the equipment. There will be no blockage, deviation of the filter belt or other phenomena that affect the safety of the process. The daily maintenance is simple and convenient, and it can be operated continuously without people for 24 hours. For the first time, continuous and fully automatic operation of sludge dewatering was realized.


4.The integrated overall design, compact design, greatly saves operating costs. Low-speed spiral extrusion technology makes the power consumption greatly reduced; the equipment is not clogged, the flushing water is greatly reduced; 24 hours of automatic unmanned operation, the labor cost is greatly reduced. Therefore, this equipment has truly become a new type of energy-saving and environmentally friendly equipment that complies with national policies.


5.The machine is designed to be very light due to the direct use of mechanical extrusion dehydration without the need for large bodies such as rollers; the body is almost entirely made of stainless steel, and the replacement parts are only the spiral shaft and the traveling ring, which has a long service life and long durability durable.


6.The volute screw sludge dewatering machine itself has the function of sludge concentration, which can directly process the aerobic sludge in the aeration tank without the need for concentration and storage units, reducing the overall space and construction cost of the sewage treatment facility.


7.The sludge is dehydrated under aerobic conditions, and the phosphorus release of the sludge in the conventional sludge concentration tank or storage tank under anoxic or anaerobic conditions will not occur, thereby improving the removal of the entire sewage treatment system Phosphorus function.
