Horizontal Wastewater Sewage Treatment Sludge Stacked Screw Plant Dehydrator
Product introduction
The stacked screw type sludge dewatering machine follows the principles of force water co direction, thin layer dewatering, appropriate pressure application, and extended dewatering path, solving the technical problems of previous generations of sludge dewatering equipment such as easy blockage, inability to handle low concentration and oily sludge, high energy consumption, and complex operation, achieving the goal of high efficiency and energy conservation in dewatering.

Working structure
The separation unit of the screw press is composed of a fixing ring and a floating ring which are stacked on each other with a small gap in between. The spiral shaft passes through it and rotates to drive the floating ring to move circumferentially. The water in the flocculated mud pie is filtered out through the gap between the fixing ring and the floating ring, and the floating ring moves circumferentially to prevent blockage. The gap between the fixing ring and the floating ring becomes smaller along the direction of the cake outlet from the thickening zone to the dewatering zone, and forced dewatering is achieved under the back pressure formed by the back pressure plate of the sludge outlet.
Working principles
The sludge is sent by the sludge transfer pump to the sludge inlet,and the flocculant is metered and sent to the flocculation mixing tank,where the sludge is fully stirred with the flocculant and flocculated. After being flocculated into large floccules,the sludge enters in the spiral separation unit from the spiral sludge inlet.The floccules in the spiral separation unit are under gravity thickening while moving towards the dewatering zone under the action of the spiral.The gap between the floating ring and the fixing ring in the dewatering zone is narrowed, and the sludge is further pressurized and dewatered under the action of the back pressure plate, and is discharged from the sludge outlet as cake.
