How to choose a screw stacker and what are the advantages?

When selecting the type of screw stacker, pay attention to the filter belt. Different characteristics of sludge have different requirements on the belt speed. It is mainly used for the dewatering of high and low concentration sludge to reduce the intensity of manual operation. The following Introduce the "methods and advantages of screw stacking machine selection" in detail.

1. Method of selection of screw stacking machine

1. Filter belt. It is stipulated that the screw stacker has the characteristics of high compressive strength, bump resistance, corrosion resistance, temperature change resistance, etc. In addition, the actual characteristics of the sludge should be considered, and suitable hand-woven patterns should be selected to make the filter belt have excellent vapor permeability. Can compare the blocking characteristics of sludge particles.

2. The deviation adjustment system software of the roller press. General equipment is carried out according to pneumatic equipment.

3. The tensioning system software of the filter belt. General equipment is also operated by pneumatic systems. The support force of the filter belt is generally controlled at 0.3-0.7MPa, and the common value is 0.5MPa.

4, with speed control. Different characteristics of sludge have different requirements for belt speed, that is, there is a belt speed control range for all specific types of sludge. You can also get high-quality mud cakes.

2. Technical advantages of screw stacking machine

1. The screw stacker is suitable for the dewatering of high and low concentration sludge. When dewatering low-concentration (2000mg/L) sludge, there is no need to build a concentration tank and a storage tank, which reduces the construction cost and reduces the release of phosphorus and the generation of anaerobic odor.

2. No blockage, reduce flushing water consumption, save water costs, and reduce the burden of internal circulation caused by the backflow of cleaning water.

3. The electric control cabinet, the flocculation mixing tank and the dewatering main body are integrated, which reduces the floor space and is simple and convenient to install.

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

5. Realize fully automatic 24-hour operation, reducing the labor intensity of operators.

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

7. The body is almost entirely made of stainless steel, which can greatly extend the service life. The replacement parts are only the screw shaft and the traveling ring, and the service cycle is long.

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