How to ensure the use of the stacked screw sludge dewatering function?
- 2020-06-22-


The stacked screw sludge dewatering machine can be widely used in municipal sewage treatment projects and water treatment systems in petrochemical, light industry, chemical fiber, paper, pharmaceutical, leather and other industrial industries. The actual operation proved that the use of the stacked screw sludge dewatering machine can create considerable economic and social benefits for customers.


In the use of snail sludge dewatering machine, the following maintenance requirements should be met:


1. According to the requirements of the snail sludge dewatering machine, the observation of the observation items and the inspection and protection of the machine are often done. For example, when inspecting the centrifugal dehydrator, pay attention to investigating the oil level of the oil tank, the oil flow of the bearing, the temperature of the cooling water and the cooling oil, the sensation of the equipment, and the reading of the ammeter. Pay attention to the water when inspecting the belt press dehydrator. Is it normal for pressure gauges, mud pressure gauges, oil gauges and other work to control the appearance?


2. Regularly check the wear condition of the wearable parts of the snail sludge dewatering machine, and replace it if necessary. The wearable parts of the belt press dehydrator include rollers, filter cloth, etc., and the wearable parts of the centrifugal dehydrator are screw conveyors.


3. When it is found that hard particles such as sand particles in the mud have caused damage to the filter belt, drum or screw conveyor, repair it immediately. If the damage is severe, it is necessary to replace it.


4. The sludge separation effect of the snail sludge dehydrator is greatly affected by temperature. For example, when using a centrifugal dehydrator, the moisture content of the mud cake in winter is 2% to 3% higher than that in summer, so the sludge should be strengthened in winter Insulation of transportation and dehydration machine room, or adding the dosage of medicament, and sometimes it is necessary to replace the dehydrating agent with very good effect.


5. Before the snail sludge dewatering machine shuts down, it is necessary to ensure that there is a sufficient water flushing time to ensure that the inside of the machine and the periphery of the machine are completely cleaned and clean, and the possibility of malodors is reduced. Otherwise, if the accumulated mud is dried on the machine, the adhesion fastness is very large, and it will be very difficult to wash in the future, which will directly affect the normal work and dehydration effect of the next dehydrator.


6. During dehydration, the dehydration effect of the dehydrator is often investigated and tested. If the solid content of the mud cake is reduced or the filtrate is turbid, measures should be adopted to deal with it in time. Investigate together whether the dehydrator equipment itself is working properly, and take measures to deal with abnormal conditions in time to prevent the dehydrator from presenting major doubts.
