Reasons and Solutions for Sludge Dewatering Press Jam

 

In general, the slugge dewatering press is rarely blocked, because the slugge dewatering press is squeezed by the relative motion of the moving ring and the fixed ring, transmitted forward by the pressure of the spiral shaft, and equipped with a backwash spray system, which can effectively prevent blocking.

However, in case of blockage, it is necessary to find out the causes. The possible causes are as follows:

1. The quality of the machine itself. The product process is poor. Some machines with poor quality may lock up when running, and mud jamming may occur.

2. Improper operation may also lead to clogging problems, such as too much mud entering and exceeding the load of equipment. The amount of mud fed exceeds the processing capacity of the equipment, the pressure load in the main body is too large, and the friction between the movable ring and the spiral shaft is increased, resulting in wear of the movable ring and the spiral shaft. Therefore, it is necessary to adjust the reasonable amount of mud fed according to the processing capacity of the whole machine to avoid overload operation. Improper operation also includes: not cleaning for a long time, not regular maintenance, etc.

3. It is related to the nature of sludge. If the sludge contains sand, oil, glue, a large amount of solid waste, and easily dried sludge, it may be blocked. In addition, if large slag blocks and metal blocks enter the dehydration main body, a filtering device shall be added at the water inlet end if necessary, otherwise the movable ring will be stuck or blocked, causing wear of the movable ring and spiral shaft.

So, if the sludge dewatering press is blocked, how should we solve it?

1. In case of blockage and jamming, power off and stop operation immediately for maintenance. Flush with plenty of water at the same time.

2. If it is only slightly blocked, try to reverse the spiral shaft or increase the flushing frequency to solve the problem.

In the process of using the sludge dewatering press, congestion happens occasionally, so customers don't need to panic. Mastering the correct operation mode can effectively improve the operating efficiency of the machine.
