The spiral sludge dewatering machine is a compact and space-saving equipment with low energy consumption, low operating costs, high energy efficiency, high technological content, easy maintenance and replacement, light weight, and convenient transportation. It is particularly suitable for small and medium-sized sewage treatment plants, township sewage treatment plants, and sewage treatment stations. This dewatering machine replaces the traditional filter cloth and centrifugal filtration methods with a unique and delicate filter body mode, reducing investment costs and improving treatment efficiency. (1) It can directly handle sludge from aeration tanks and secondary sedimentation tanks, eliminating the need for building sludge concentration tanks and sludge storage tanks, reducing the overall construction investment cost, and avoiding the problem of phosphorus release in traditional sludge concentration tanks, enhancing the phosphorus removal function of the sewage treatment system. (2) It saves the costs of equipment for mixing machines and other supporting facilities. (3) It saves the costs of air compressors, flushing pumps, and other supporting equipment for sludge dewatering. (4) It has a small footprint, reducing the construction investment for the dewatering machine room, integrating sewage and sludge, reducing the processing load of subsequent biochemical reactors, and lowering the operating costs of the sewage treatment system.
The spiral sludge dewatering machine utilizes the principle of screw extrusion. Through the strong squeezing force generated by the changes in screw diameter and pitch, as well as the tiny gaps between the moving ring and the fixed ring, it achieves the dewatering of sludge in a new type of solid-liquid separation equipment.
Composition of the institution
The spiral sludge dewatering machine is composed of a spiral body, a driving device, a filtrate tank, a mixing system, a frame, etc. When the spiral sludge dewatering machine is working, the sludge is lifted to the mixing tank by the sludge pump. At this time, the dosing pump also quantitatively delivers the liquid medicine to the mixing tank, and the stirring motor drives the entire mixing system to fully mix the sludge with the liquid medicine, thereby generating flocs. When the liquid level r
