Screw sludge dewatering machine advanced technology and smart construction

- May 31, 2018-

Since the screw sludge dewatering machine cleverly uses the automatic update filter cake filtration technology instead of the traditional filter screen filtration, it ensures the continuous and stable mud-water separation effect of the dewatering machine; and the strong extrusion force generated by the screw diameter and pitch change, and the moving ring Small gaps between the fixing rings enable squeezed dewatering of the sludge.


As a new type of solid-liquid separation equipment, the screw sludge dewatering machine can not only reduce the sedimentation tank and the sludge concentration tank, but also save the construction cost of the sewage station. The sludge is concentrated in the enrichment section and then transported to the dehydration department. During the advancement process, the internal pressure is generated and the volume is continuously reduced as the filter joint and the pitch become smaller and the back pressure plate is blocked. The purpose of dehydration.


From the structural point of view, the main part of the screw sludge dewatering machine is stacked on one another by a fixed ring and a moving ring, and the screw shaft penetrates the filtering device formed therein. The front section is a concentration section, and the rear section is a dehydration section. The filter seam formed between the fixed ring and the moving ring and the pitch of the screw shaft gradually become smaller from the enrichment part to the dewatering part; and the rotation of the screw shaft thereof continuously promotes the sludge transport from the enrichment part to the dehydration part, Drive swimming ring to clean the filter to prevent clogging.


Advanced technology coupled with unique construction makes the screw sludge dewatering machine possess a series of unique advantages. It can be widely used not only in municipal sewage, food, beverage, slaughtering and breeding, printing and dyeing, petrochemical industry, papermaking, leather, Sludge dewatering in pharmaceutical and other industries; can also be applied to high and low concentrations of sludge, especially oily sludge.


Spiral sludge dewatering machine adopts automatic control of sludge extraction, liquid injection, and sludge discharge. It does not require personnel to operate the equipment, and operation will not cause clogging, filter belt deviation, or other phenomena that affect process safety. Routine maintenance Easy to maintain, no one can run continuously for 24 hours.


The integrated design of the spiral sludge dewatering machine has a compact design and greatly reduces operating costs. In addition, the sludge is operated under such a slow working condition and the odor does not spread, thus creating a very good operating environment. In addition, spiral sludge dewatering machines have significant phosphorus removal capabilities.
