Attention to the operation of the stacked screw sludge dewatering machine

- Nov 05, 2020-

The stacked screw sludge dewatering machine is a new type of sludge dewatering equipment, which is loved by people for its water-saving, power-saving, labor-saving, fully automatic operation, and no clogging. Its operation is simple and almost fully automatic. The material is mostly made of 304 stainless steel. The internal screw shaft is made of anti-corrosion and wear-resistant alloy. Despite so many advantages, there are several operating procedures that need to be operated in the actual operation process. Keep in mind that it will cause unnecessary economic losses.

1. When starting the test machine, first check the rotation direction of the screw shaft to see if it is rotating in the correct direction. If it rotates in the reverse direction, not only the sludge cannot be released, but also the screw shaft of the motor will be damaged.
2. Before each shutdown, the machine must be idle for more than 10 minutes to ensure that the sludge in the cavity of the screw shaft is completely removed, and the main section of the effective dehydration is rinsed with a spray to prevent the sludge from drying out when the machine is turned on next time And cause damage to the stacking screw host.
3. The coordination between the back pressure plate and the spindle motor cannot be ignored.

The sludge from the screw stacker has a moisture content between 70% and 85%. Many customers mistakenly think that when working, they can tighten the back pressure plate to make the sludge squeeze dry. However, when the spiral cavity is full of sludge, if the pressure plate is too tight and the sludge cannot be removed in time, it will cause overload to the motor, which will easily burn the spindle motor and deform the screw shaft. Unnecessary losses.

The correct operation is: when the screw stack sludge dewatering machine starts to start, the back pressure plate can be tightened. When the cavity of the screw stack sludge dewatering machine is filled with sludge, adjust the back pressure plate in time to allow the sludge to be discharged smoothly. . Never pursue the solid content of the sludge and adjust the back pressure plate very tightly. If the adjustment is very tight, although the solid content of the sludge at the sludge outlet will increase, a lot of mud will be in the gap between the fixed ring and the fixed ring. Filter out, affect the clarity of the discharged water

The above points are the problems that must be paid attention to during the operation of the stacked screw sludge dewatering machine. It must be kept in mind to improve efficiency and reduce losses.
