Causes Of Failure Of Stacked Sludge Dewatering Machine

Jul 18, 2020

Stacked sludge dewatering machine is widely used in the manufacturing industry. It is suitable for the de-drying of high and low concentration sludge. It occupies a small area and does not require the basic construction of an extraction tank. Easy to block, with self-cleaning effect. However, because of the product quality problems of each manufacturer and the specific solution status of the owner, it is inevitable that common failures will occur.

Here is an analysis of what causes the common failures of the Stacked Sludge Dewatering Machine?

The use of sludge dewatering machine is becoming more and more common, and many manufacturing industries are used to treat sewage and sludge. The sludge dewatering machine can operate stably under all normal conditions, and there are no parts that must be replaced on time. The usual sludge treatment work can be carried out for ten years as a day.

Most of the common faults of the Stacked Sludge Dewatering Machine are sludge and shaft blocking.

The key reason for blocking the shaft is because of the composition problem of silt. The stacking screw dehydrator is easy to use to solve the organic chemical sludge, and solve the problem of shaft blockage when solving the inorganic sludge. Inorganic sludge is very easy to dry out. If the sludge is too dry and sticks to the spiral shaft when it is solved in the line cavity of the machine and equipment, with the increase in the amount of sludge, the sludge on the shaft becomes more and more. It is not allowed to discharge from the mud outlet at the end, and squeeze in the middle of the ring, resulting in common failures such as shaft blockage and mud leakage. Therefore, customers must be clear about their own sludge characteristics when selecting machinery and equipment.

The thin sludge from the snail sludge dehydrator is mainly caused by the poor condition of the inclined plate sedimentation tank. The sludge sludge sedimentation tank determines the water content after the sludge treatment at a fairly large level. If the inclined plate sedimentation tank is not very good, the water content of the sludge removed is high. In addition, there is another key reason, that is, the gap between the ring pieces of the machinery and equipment is too wide. The production and processing of the ring pieces of some manufacturers is to control the cost, without mirror processing, no ground stress, and the flatness of the ring pieces. Insufficient, the sound ring is damaged during operation to prevent damage. Some manufacturers increase the thickness of the gasket to increase the gap between the ring, so that the ring is not worn, but the drying rate of the machinery and equipment is also reduced. , The water content of the sludge after drying is very high.


It is not difficult to see that the main reasons for the common failures of the snail sludge dewatering machine are the sludge characteristics, the inclined plate sedimentation tank, and the ring gap. This is all a difficult problem that customers must consider when selecting machinery and equipment.
