Volute Screw Press

 

1. Concentration: When the spiral push shaft rotates, the multiple solid and active laminations located on the periphery of the push shaft move relative to each other. Under the action of gravity, water is filtered out from the gaps between the relatively moving laminations, achieving rapid concentration.

2. Dehydration: The concentrated sludge continues to move forward with the rotation of the spiral shaft; along the direction of the mud cake outlet, the pitch of the spiral shaft gradually becomes smaller, the gap between the rings also gradually becomes smaller, and the volume of the spiral cavity becomes smaller. Continuously shrinking; under the action of the back pressure plate at the outlet, the internal pressure gradually increases. Driven by the continuous operation of the spiral push shaft, the water in the sludge is extruded and discharged. The solid content of the filter cake continues to increase, and finally the sludge is realized. of continuous dehydration.

3. Self-cleaning: The rotation of the spiral shaft drives the moving ring to continuously rotate. The equipment relies on the movement between the fixed ring and the moving ring to achieve a continuous self-cleaning process, thereby cleverly avoiding the common clogging problem of traditional dehydrators.

 

 

1. Suitable for sludge in municipal sewage, food, beverage, chemical, leather, welding materials, papermaking, printing and dyeing, pharmaceutical and other industries.

2. Suitable for dehydration of high and low concentration sludge. When dehydrating low-concentration (2000mg/L~) sludge, there is no need to build a concentration tank or a storage tank, which reduces construction costs, reduces the release of phosphorus and the generation of anaerobic ozone.

3. Has self-cleaning function. There is no need to clean the filter seams to prevent clogging, which reduces flushing water consumption and reduces the burden on the internal circulation.

4. The rotation speed of the spiral shaft is about 2~3 rpm, and the consumption is extremely low.

5. Few failures, low noise and vibration, and safe operation.
