Structure and Working Principle The core part of the screw sludge dewatering machine is one or several groups of filter units composed of a screw drive shaft, multiple fixed laminations and multiple floating laminations. Each filter unit is divided into two parts: concentration section and dehydration section. From the sewage inlet of the concentration section to the mud cake outlet of the dewatering section, the pitch of the screw shaft gradually decreases, and the gap between the fixed ring and the moving ring gradually changes. small. There is a back pressure plate at the sludge outlet to adjust the pressure in the spiral cavity. The spiral sludge dewatering machine completes the thickening and squeezing and dewatering of the sludge in one cylinder, replacing the traditional filter cloth and centrifugal filtration method with a unique and subtle filter body mode. Working Principle 1. Thickening: When the screw drive shaft rotates, the multiple solid and active laminations arranged on the periphery of the drive shaft move relative to each other. Under the action of gravity, water is filtered out of the relatively moving lamination gap to achieve rapid concentration. 2. Dewatering: The concentrated sludge moves forward with the rotation of the screw shaft; along the direction of the mud cake outlet, the pitch of the screw shaft gradually decreases, and the gap between the rings gradually decreases, and the volume of the spiral cavity Constantly shrinking; under the action of the back pressure plate at the outlet, the internal pressure gradually increases. Under the continuous continuous operation of the screw drive shaft, the water in the sludge is squeezed and discharged, and the solid content of the filter cake continues to increase, finally achieving sludge Continuous dehydration. 3. Self-cleaning: The rotation of the screw shaft pushes the moving ring to continuously rotate. The equipment relies on the movement between the fixed ring and the moving ring to achieve a continuous self-cleaning process, thereby cleverly avoiding the common blocking problem of traditional dehydrators. Main Features The main body of the screw sludge dewatering machine is composed of multiple fixed rings, swimming rings and spiral filtering parts, which organically combines filtration and thickening technology and pressing technology to complete the thickening and pressing and dewatering of sludge in one cylinder; In the cavity, it uses the relative swimming between the fixed and moving laminations to quickly discharge the filtrate without clogging; in the dehydration cavity, the continuous contraction of the volume of the spiral cavity is used to enhance the internal pressure and the pressure regulating mechanism of the back pressure plate. The unique and subtle filter mode replaces the traditional filter cloth and centrifugal filtration methods, and its advanced solid-liquid separation and self-cleaning technology will create a new era of sludge dewatering. 4.5m3/h Screw Press Sludge Dewatering Machine , Chemical Sludge Dewatering Equipment 0 4.5m3/h Screw Press Sludge Dewatering Machine , Chemical Sludge Dewatering Equipment 1
