What are the technical advantages of screw stacking machine and how to select it?

The screw stacker can be applied to the dewatering of high and low concentration sludge, and can realize full-automatic 24-hour operation and reduce the labor intensity of operators. In the process of screw stacker, pay attention to the problems such as excellent air permeability of filter belt. The following is a specific introduction to "technical advantages and selection of screw stacker".

1、 Technical advantages of screw stacker

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

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

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

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

5. Realize full-automatic 24-hour operation and reduce the labor intensity of operators.

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

7. Almost all the body is made of stainless steel, which can greatly prolong the service life. Only the spiral shaft and traveling ring are replaced, which has a long service life.

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

2、 How to select the type of screw stacking machine

1. Filter belt. It is specified that the screw stacker has high compressive strength, bump resistance, corrosion resistance, temperature change resistance and other characteristics. In addition, considering the actual characteristics of sludge, select suitable manual weaving lines to make the filter belt have excellent steam permeability and better blocking characteristics than sludge particles.

2. Deviation adjustment system software of roller. General equipment shall be carried out according to pneumatic equipment.

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

4. Belt speed control. Sludge with different characteristics has different regulations on belt speed, that is, there is a belt speed control category for all a specific sludge. Within this range, the dewatering system software can not only solve the specific working ability, but also obtain high-quality mud cake.
