Sludge Dewatering Machine Screw Filter Press
Product Description
Screw Filter press machine can generate the strong extrusion force through the changes of screw diameter and pitch, and the tiny gap between the moving ring and the fixed ring, the sludge is squeezed and dehydrated, a new type of solid-liquid separation equipment.
The main body of the dehydrator is a filter device formed by a fixed ring and a floating ring stacked on each other, and the screw shaft runs through it.
The filter gap formed between the fixed ring and the moving ring and the pitch of the screw shaft gradually decrease from the dewatering section to the pressing section.
How to work:
1. Dehydration: When the screw push shaft rotates, the rings set on the periphery of the push shaft move relatively, and under the action of gravity, the water is filtered out from the lamination gap to achieve rapid concentration.
2. Pressing: The concentrated sludge moves forward with the rotation of the screw shaft. Along the outlet direction of the mud cake, the pitch of the screw shaft gradually decreases, the gap between the rings also gradually decreases, and the volume of the spiral cavity gradually decreases. Continuously shrinking; under the action of the back pressure plate at the outlet, the internal pressure gradually increases, and under the continuous operation of the screw shaft, the water in the sludge is squeezed and discharged, and the solid content of the filter cake is continuously increased to realize the sludge. Continuous dehydration.
3. Cleaning: spray and clean with a nozzle

Advantages:
1. Suitable for sludge in municipal, food, beverage, slaughtering, breeding, printing and dyeing, petrochemical, paper making, leather, welding consumables, pharmaceuticals, and other industries.
2. The equipment is not easy to be blocked: The dynamic and static ring filter slit structure makes the equipment not easy to block, and there is no need to carry out a lot of cleaning to prevent the filter slit from being blocked, reducing the water consumption for flushing, reducing the burden of internal circulation, and solving the troubles caused by the blockage of traditional dehydration equipment.
3. It is suitable for dewatering high and low-concentration sludge. When low-concentration (2000 mg/L) sludge is dewatered, there is no need to build a concentration tank and a storage tank, which reduces construction costs and reduces the release of phosphorus and the generation of anaerobic odor.
4. High level of automation: The screw-type sludge dewatering machine adopts automatic control from sludge extraction, liquid injection, and sludge cake discharge. , No need for personnel to operate the equipment, no blockage, track deviation, or other phenomena affecting process safety will occur during operation, and daily maintenance is simple.
5. Energy saving and environmental protection: integrated overall design, compact design, greatly saving operating costs. The low-speed screw extrusion technology greatly reduces the power consumption, the equipment is not blocked, the flushing water is greatly reduced, the 24-hour automatic unmanned operation, and the labor cost is greatly reduced.
6. No secondary pollution: the rotation speed of the screw shaft is about 2-3 rpm, there is no vibration, and the noise is very small.
7. The body is light and durable: The machine is designed to be quite light due to the direct use of mechanical extrusion dehydration and no need for large bodies such as rollers; the body is almost entirely made of stainless steel, and the replacement parts are only the screw shaft and the swimming ring, which has a long service life and is durable.
8. The screw-type sludge dewatering machine itself has the function of sludge concentration, which directly treats the aerobic sludge in the aeration tank without the need for concentration and storage units, which reduces the overall footprint and construction cost of the sewage treatment facility.
