Sludge dewatering machine can carry out the separation of liquid-solid, liquid-liquid-solid suspension. In China's coastal areas there are many chemical dyeing and printing factories, textile factories, paper mills, electroplating factories, sewage treatment plants and other chemical wastewater pollution enterprise sewage treatment will produce a large amount of activated sludge, when the sludge into the high-speed rotating drum, due to the centrifugal force by the role of the size of the different solid-phase particles in the suspension (sludge) by the impact of the larger centrifugal force was settled to the drum's inner wall, the suspension of the clean (liquid) phase By the influence of relatively small centrifugal force is settled to the inner side of the solid-phase material, and the drum rotating direction of the same screw feeder is also doing high-speed rotation, the two by the differential speed to produce a stable speed difference, the solid-phase particles settled to the inner wall of the drum (sludge) by the screw feeder will be transported to the solid-phase material out of the drum, the clear phase of the liquid by the clear-phase outlet of the drum out of the sludge separation and dewatering process is finally completed.
LWJ decanter centrifuge (solid-liquid separator):
1, has a compact structure, in the same processing capacity of the machine's small size, light weight, relatively easy to move;
2, large capacity, good separation performance, wide range of applications;
3, high solid-phase recovery, low operating costs, no filter mesh filter cloth;
4、Automatic continuous operation, operation, simple use, easy installation and maintenance and other advantages. It has been widely used in many industrial and mining fields such as geology and minerals, petroleum, chemical industry, metallurgy, pharmacy and environmental protection.
Sludge dewatering machine performance characteristics:
The main parts are made of high quality carbon steel or stainless steel. The pusher adopts special wear-resistant measures, which can be set with hard alloy wear-resistant tile or surfacing hard alloy protective layer. Adopt cycloid differential, low noise, strong bearing capacity.
1. Single compact structure, covers an area of 2-3 square meters, running smoothly. It can unload automatically and operate continuously, and workers only need to operate the power cabinet, which is clean and hygienic.
2. Wide adaptability to the material, can be separated from a wide range of solid-phase particle size (0.005 ~ 2mm), in the solid-phase particle size is not uniform when the separation can be carried out as usual. Dosing depends on the material, generally do not need to add drugs, cost savings.
3. According to the industry to choose the material, the centrifuge can choose 304, 316 stainless steel material manufacturing, special industries can use explosion-proof motor.
4. The equipment occupies small space, convenient transportation and lifting, sometimes in order to save the space occupied by the machine and realize the centralized preparation and purification process of slurry, the device can also be placed on the containerized slurry tank, but the equipment must be provided with a solid bottom support, and provide reliable safety protection facilities for the operator. For construction piling mud treatment, the mud purification equipment consists of mud feeding system, dosing system, desanding purification system, mud separator, slag discharge system, recycling mud tank and blending mud tank.
