Stacked Spiral Sludge Dehydrator

Introduction Of Stacked Spiral Sludge Dehydrator

The stacked screw sludge dewatering machine is a kind of equipment with compact design, small footprint, low energy consumption, low operating cost, high energy saving, high technology content,easy maintenance and replacement, small weight, and easy handling. , Especially suitable for small and medium sewage plants, township sewage plants, sewage treatment stations. The dehydrator replaces the traditional filter cloth and centrifugal filtration method with a unique and subtle filter body mode, which reduces investment costs and improves processing efficiency.

(1) It can directly treat the sludge in the aeration tank and the secondary settling tank, without the need to build sludge thickening tanks and sludge storage tanks, reducing the overall investment cost of infrastructure, and avoiding the problem of phosphorus release in traditional sludge thickening tanks, and improving sewage treatment System dephosphorization function.

(2) Save the cost of supporting equipment for structures such as mixers

(3) Save the cost of sludge dewatering equipment such as air compressors and flushing pumps

(4) The area is small, the civil construction investment of the dehydration machine room is reduced, the sewage sludge is integrated, the subsequent processing load of the biochemical reactor is reduced, and the operating cost of the sewage treatment system is reduced.

Working Principle Of Stacked Spiral Sludge Dehydrator

The equipment is mainly composed of coagulation tank, stacking screw main body, host base, water collection tank, spray pipe, spindle motor, mixing motor, electric control cabinet, etc.The stacked screw sludge dewatering machine uses the principle of screw extrusion, through the strong extrusion force generated by the change of screw diameter and pitch, as well as the tiny gap between the moving ring and the fixed ring, to achieve the dehydrate. A new type of solid-liquid separation equipment for squeezing and dewatering sludge.

The sludge dewatering machine adopts a multi-overlap spiral filter press method, which has the function of self-cleaning filter slits, which does not block, saves water and electricity, and is durable. It creates direct dewatering of low-concentration sludge (2000mg/L～) The first of its kind, it can realize 24-hour continuous unmanned operation, while greatly reducing the cost of design, construction, operation and maintenance management.

The stacking screw sludge dewatering machine is composed of stacking screw body, driving device,filtrate tank, mixing system, frame body and so on. When the snail 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 transports the liquid to the mixing tank, and the stirring motor drives the entire mixing system to combine the sludge with the liquid. Fully mix to produce alum. When the liquid level reaches the upper level of the liquid level sensor, the liquid level sensor will get a signal at this time, so that the motor of the main body of the stacked screw starts to press and filter the sludge flowing into the main body of the stacked screw. Under the action of the sludge, the sludge is lifted to the sludge outlet step by step, and the filtrate flows out from the gap between the fixed ring and the moving ring.
