The daily maintenance of the screw trap sludge dehydrator. Since its application in the field of sludge dewatering, the screw trap sludge dehydrator has gradually replaced the frame sludge dehydrator and belt sludge dehydrator with its advantages of non blocking, energy saving, low operation cost, long service life and simple operation. It is widely used in municipal sewage plant, printing and dyeing, papermaking, food, aquaculture, chemical industry and other industries. Although the failure rate of the screw stacker sludge dehydrator is very low and it can run stably for ten years, the operators should also do a good job in daily inspection and maintenance of the screw stacker to ensure that the equipment can achieve high efficiency and good effect of dehydration, and extend the service life of the screw stacker and supporting equipment. The daily maintenance of the sludge dehydrator is mainly to carry out the daily inspection and regular inspection of the equipment. It is an important work to grasp the condition of the equipment in time, find out and eliminate the hidden dangers of the equipment through inspection, and prevent sudden failures and accidents, so as to ensure the normal operation of the equipment.

Daily inspection is to check the technical conditions of all parts of the equipment by the operators according to the specified standards, so as to discover the hidden dangers in time and take countermeasures. Mainly check the following aspects: motor, whether normal operation, whether there is abnormal noise, whether there is vibration. Whether the pressing plate, the set gap and the moisture content of the cement cake change too much. Check whether the solid content of the filtrate of the main body of Spirillum is abnormal. Whether there is sludge accumulation around the return pipe of the metering tank. Whether proper alum is formed in flocculation mixing tank.
