What to pay attention to when using the stacked screw sludge dewatering machine
- 2021-02-22-

The screw-on sludge dehydrator is an important part of the dewatering system. Other equipment serves for the screw-on sludge dehydrator. Therefore, to ensure the normal operation of the screw-on sludge dehydrator, the normal operation of other equipment must be ensured.

The following problems will occur during the operation of the stacked screw sludge dewatering machine:

1. Filter belt deviation: stacked screw type sludge dewatering machine centrifugal type: all three types of sludge can be used, but high energy consumption and high speed lead to high noise. There are certain differences in the habits of various sludge dewatering machines. The common models of the domestic screw sludge dewatering machine are: centrifugal type, filter belt type, spiral ring type and plate and frame type. The deviation of the filter belt is the deviation of the filter belt beyond the correction lever, and it hits the deviation alarm travel switch. Under normal conditions, the filter belt shifts to the deviation correction control rod, the correction cylinder will adjust the deviation direction of the filter belt, and the deviation will not occur. The deviation may be because the reversing valve does not receive the filter belt deviation signal, and the deviation correction cylinder does not work. In this situation, check the air pressure, the integrity of the correction components, the integrity of the correction circuit, the integrity of the correction air pipe, and the working condition of the correction roller.

2. Poor filtration performance of the filter belt: The reasons for the poor performance of the filter belt may be insufficient backwashing water pressure, clogged nozzles, poor sludge flocculation, and large amount of flocculant solution.

3. Sludge running from the screw-on sludge dewatering machine: The sludge running from the screw-on sludge dewatering machine may be due to the large amount of sludge and poor flocculation.

4. Thin sludge cake out of the screw-type sludge dewatering machine: The thin sludge cake may be due to the low concentration of the remaining sludge, the low amount of sludge, poor flocculation, and the speed of the pressing section is too fast.
