Volute sludge dewatering machine is a very common water treatment equipment, which in addition to sludge dewatering, but also to complete the concentration and self-cleaning and other sectors can be widely used in municipal sewage treatment works and petrochemicals, Light industry, chemical fiber, paper, pharmaceutical, leather and other industrial water treatment system.
When the spiral screw shaft of the volute sludge dewatering machine rotates, the multiple fixed laminations located on the periphery of the propeller shaft move relative to each other. Under the action of gravity, water is filtered out from the relatively moving lamination gaps to achieve rapid concentration. The concentrated sludge will move forward along with the rotation of the screw shaft. Under the action of the back pressure plate at the outlet, the sludge in the sludge will be squeezed out and the solid content of the filter cake will increase continuously to realize the sludge Continuous dehydration.
The rotation of the screw shaft in the volute sludge dewatering machine can drive the traveling ring to rotate constantly. The equipment relies on the movement between the fixed ring and the traveling ring to realize the continuous self-cleaning process, so that the traditional dehydrator is ingeniously avoided The problem of congestion.
This kind of sludge dewatering machine is very suitable for the dewatering of high and low concentration sludge. Especially in the case of dewatering of low concentration sludge, there is no need to build thickened pool, storage pool and reduce the construction of the multi-screw sludge dewatering machine Cost, reduce the release of phosphorus and anaerobic odor generation.
It can be very intuitive to see that the structure of the stack screw sludge dewatering machine design is very compact, so small footprint, easy maintenance and replacement; small weight, easy handling. Plus it has a self-cleaning function, do not need to prevent clogged filter cleaning, reduce flushing water, reduce the burden on internal circulation.
Volute sludge dewatering machine through the control cabinet, and the bubble machine, into the pump, dosing pumps and other devices linked to achieve 24 hours of continuous unmanned operation. In addition, almost all of its body is made of stainless steel, to maximize the service life, making the design, construction, operating costs greatly reduced.
