Large Processing Capacity Belt Filter Press for Sludge Dewatering

    Belt filter press is a new generation of dehydration equipment, it has the advantages of large processing capacity, high dehydration efficiency (from the slurry concentration of 0.8-3% can be directly increased to more than 28-35%), low energy consumption，etc. The belt filter press not only solves the problem of running material when the conventional filter press dehydrates the raw material, but also solves the problem of low material pressure at both ends of the filter screen. Because the new model has a pre-dewatering network case, the natural gravity dewatering area of the sludge is lengthened, and the Internet is not squeezed, the mesh is not easy to be blocked by fiber, sludge. So compared with the traditional filter press, its advantages come out. It can reduce the amount of mesh belt and amide by more than 10-30%, and the structure is simple, easy to install, is the ideal product of sludge pressure filtration, dehydration. Belt filter press can be widely used in urban sewage, printing and dyeing, textile, papermaking, food, pharmaceutical, chemical, metallurgy, petroleum and other fields of sludge (or material) dehydration.

Working Principle
The material passes through the conveyor, transported to the hopper of the dewatering machine, and evenly laid on the filter belt through the auger. The filter belt is leveled by the height of the material layer with the operation of the equipment so that the thickness of the material is completely uniform. Then, the upper and lower two ring-shaped filter belts are completely clamped, and the material layer is clamped by the driving roller, and the pair of rollers in the dewatering zone is mechanically pressed several times to press out a large amount of water. According to the characteristics of the material, the extrusion force is automatically adjusted to meet the customer's requirements for material moisture.
