How to clean the volute screw press sludge dehydrator correctly

The volute screw press sludge dehydrator has a self-cleaning function, which can ensure that it will not be blocked during normal operation, and can also extend the service life of the stacked screw sludge dewatering machine. The rotation of the screw shaft promotes the continuous rolling of the moving ring, and the equipment relies on the movement between the fixed ring and the moving ring to realize a continuous self-cleaning process, thus miraculously avoiding the common clogging problem of traditional dehydrators.

However, it is inevitable that when the nature of the sludge or the environment changes, sludge or larger particles will be stuck in it. Therefore, regular inspection and active cleaning are also very important maintenance and protection processes for the stacked screw sludge dewatering machine.

Generally, it needs to be cleaned once every five months of operation to ensure the low moisture content of the extruded solids. If it is found that the liquid discharged from the liquid outlet is reduced or the water content of the discharged solid is high during work, you can stop and start the operation several times independently.

Slowly rotate the coupling or pulley of the volute screw press sludge dehydrator by hand to check whether the pump rotation is flexible and stable and whether there is any debris in the pump and whether there is any collision with the parts; check whether the bearing has noise and whether the cooperation is loose; Check whether the tightness of the packing of the stacked screw sludge dewatering machine is suitable and whether the tightness of the transmission belt is suitable. If abnormalities are found, they should be cleaned. For centrifugal pumps, you should check whether the gate valve is closed. Note that after the pump is started, the closing time of the gate valve should not exceed 3-5 minutes, otherwise the parts will be damaged due to the heat generated by the water circulation in the pump. The pumping equipment that needs irrigation and diversion should be irrigation and diversion, and when irrigation and diversion, use water rolling coupling or drive pulley to drain the air in the impeller of the water pump.
