Wear-free type stacking screw dehydrator

Overview of stacked screw sludge dehydrator

Stacked screw sludge dehydrator is a compact design of small space, low energy consumption, low operating costs, high energy saving and high technology content, easy to repair and replace, small weight, easy to handle the equipment is especially suitable for small and medium-sized sewage plant, township sewage plant, sewage treatment station.The dehydrator replaces the traditional filter cloth and centrifugal filtration with a unique and delicate filter mode, reducing the investment cost and improving the treatment efficiency.

Features of stacked screw sludge dehydrator:

(1) the aeration tank and secondary sedimentation tank sludge can be directly treated, no need to build sludge concentration tank and sludge storage tank, reduce the overall investment cost of infrastructure, and avoid the problem of phosphorus release in traditional sludge concentration tank, improve the dephosphorization function of sewage treatment system.(2) to save the cost of supporting equipment for mixer and other structures (3) to save the cost of supporting equipment for sludge dehydration such as air compressor and washing pump (4) to cover a small area, reduce the civil construction investment in the dehydration machine room, integrate sewage sludge, reduce the subsequent biochemical reactor treatment load, and reduce the running cost of the sewage treatment system.

Integrated concentration and dehydration, no sludge concentration tank, no filter cloth, no clogging, self-cleaning, suitable for oily sludge, low speed operation, no noise, ultra-low energy consumption, automatic control, simple operation and management.

Screw conveyor of the screw blade entity helicoid, belt type spiral blades of screw surface and surface three forms, among them, the spiral vane surface application is relatively small, it is mainly used for transporting materials in large viscosity and compressibility of the screw surface type, in complete conveying operation process, at the same time with and complete mixing, mixing of materials, and other functions.
