Sludge Dewatering Screw Press



Sludge Dewatering Screw Press
Detailed introduction:
Structural principle

  The main body of the dehydrator is a filtering device which is composed of a fixed ring and a swimming ring, and a spiral shaft runs through it. The small movable filter gap formed between the fixed ring and the moving ring is used to filter the filtrate. The inner cavity formed by the spiral shaft and the ring plate is filled with flocculated particles, which turns to the back pressure plate at the end. In the dynamic process, the mud cake is transported and extruded. The spiral shaft is rotated and pushed to continuously drive the moving ring to move up, down, left and right to clean the filter seam to prevent blockage.
Applicable industries

  It is suitable for municipal sewage, domestic sewage, food, beverage, chemical industry, leather, welding materials, papermaking, printing and dyeing, pharmacy, electroplating, oil field, coal mine, wine making, animal husbandry, kitchen wastewater, water plant, power plant, steel plant and other industries.

Technical advantages

1. It is suitable for dewatering of high and low concentration sludge. When the sludge with low concentration (2000mg / L) is dewatered, there is no need to build thickening tank and storage tank, which can reduce the construction cost, release phosphorus and produce anaerobic odor.

2. It is not blocked, reduces the water consumption, saves the water cost and reduces the internal circulation burden caused by the return of cleaning water.

3. The electric control cabinet, flocculation mixing tank and dehydration main body are integrated to reduce the floor area, and the installation is simple and convenient.

4. The dehydrator is basically in closed operation, and the treatment is stable and timely, so that the odor on site is reduced to low, and the working environment of workers is improved.

5. Realize automatic 24-hour operation, less labor intensity of operation workers.

6. The speed of screw shaft is low, 2-3 revolutions per minute, low power consumption, and there is no vibration and noise on site.

7. Almost all the body is made of stainless steel, which can greatly extend the service life. The replacement parts only have spiral shaft and floating ring, which has a long service life.

8. The daily maintenance time is short and the maintenance work is simple.
