Screw stack sludge dewatering machine

Description

The spiral stacking sludge dewatering machine is an efficient sludge treatment equipment, which is mainly used to dehydrate sludge with high moisture content to mud cake with low moisture content. Its core structure consists of a stack of fixed rings and floating rings, and the spiral shaft pushes the sludge to achieve integrated concentration and dehydration. The spiral stacking sludge dewatering machine has the following main features:
. High-efficiency dehydration: Through the rotation of the spiral shaft, the sludge undergoes gravity concentration in the concentration section, and then in the dehydration section, the sludge is deeply dehydrated through the pushing of the spiral shaft and the squeezing of the filter seam, and finally the moisture content of the sludge is reduced to 60%-80%.
. Self-cleaning design: The spiral stacking sludge dewatering machine adopts a unique self-cleaning design. The floating ring automatically cleans the filter seam with the movement of the spiral shaft to prevent blockage and ensure stable operation of the equipment.
. Modular design: The equipment adopts a modular integrated design, which is easy to deploy and transport quickly and is suitable for various dredging sites. 3. .‌Automatic control‌: Equipped with advanced automatic control system, it can automatically adjust key parameters according to the properties and processing volume of sludge, reduce manual intervention and reduce labor costs.
.‌Wide applicability‌: It is suitable for sewage treatment, food processing, chemical production and other fields, with the advantages of low infrastructure cost and high degree of automation.
Working principle
The working principle of the spiral stack sludge dewatering machine combines the dual effects of gravity concentration and mechanical extrusion of sludge. After the sludge enters the equipment through the feed port, it first undergoes gravity concentration in the concentration section, and then achieves deep dehydration in the dehydration section through the pushing of the spiral shaft and the squeezing of the filter seam. Finally, the sludge is squeezed into a mud cake with a low moisture content and discharged.
Application scenario
The spiral stack sludge dewatering machine is widely used in sludge treatment in urban sewage treatment plants, dehydration of food processing waste residues, and treatment of chemical production waste. For example, in the relocation and expansion project of urban sewage treatment plants, spiral stack sludge dewatering machines are widely used due to their advantages of low infrastructure cost and high degree of automation.
