New Environment-friendly Sludge Treatment Equipment

What is a screw filter press？

Screw filter press is known as stack screw type sludge dehydrator, also commonly known as stack screw dehydrator, stack type dehydrator, generally known as sludge dehydrator. It is a new type of environmental protection, energy saving and efficient sludge treatment equipment. Mainly used in municipal sewage treatment engineering and petrochemical, light industry, chemical fiber, papermaking, pharmaceutical, leather and other industries of sludge water treatment system.

Structure and working principle:

Text Description: 
1. The main operating parts of the stack screw are spiral shaft, moving ring and fixed ring. 
2. The spiral axis runs through the whole body, from bottom to top is the enrichment section and dehydration section in turn. 
3. The machine starts, the spiral shaft is pushed forward, and the pitch keeps getting smaller. 
4, the fixed ring and the moving ring move with each other, with the smaller pitch, continuous forward extrusion, more and more pressure. 
5. While the two rings are constantly moving, they are constantly cleaning the filter joints. 
6. The sludge is extruded and discharged by the braking and pressure of the pressed plate.

Type of screw stacking machine: 
Key parameters to know: 
1, every day to deal with the sludge (mud), that is, the amount of mud. 
2. Sludge properties and concentration 
Assuming you need to process 100 square meters of mud per day, the screw stack machine theoretically runs 24 hours a day, that is, it needs to process 100/24≈4 square meters per hour

Explain

1. When the sludge is raw water, residual sludge or chemical sludge and the concentration is 0.2%, if it is required to treat 4 cubic meters per hour, model 132 or model 201 can be selected. Generally, 201 is the majority. 
2. When the sludge is raw water, residual sludge or chemical sludge and the concentration is 1.0%, if the treatment rate is 4 cubic meters per hour, model 302 (with excess capacity) can be selected, and 301 can also be achieved in the specific experiment. 
3, when the sludge is scum, air floating sludge, choose 302 model.
4. When the sludge is mixed sludge and the concentration is 3%, Model 301 is selected. 
5. In the table, the first behavior is the free dry mud treatment amount, and the second behavior is the mud inlet amount. 

In this way, you can choose your own filter press type according to your own sludge treatment volume and concentration. You can also let me know the situation, let me customize the service for you.
