What is the reason for the drop of mud after the screw stacker is dehydrated?


Screw stacking machine, short for screw stacking sludge dewatering machine, is a water treatment system widely used in municipal sewage treatment projects and petrochemical, light industry, chemical fiber, papermaking, pharmaceutical, leather and other industrial industries. The actual operating conditions have proved that the sludge dewatering can create considerable economic and social benefits for customers. Do you know the reason why the mud drops after the screw stacking machine is dehydrated? Below is a summary of the screw stacking machine manufacturer's editor, I hope it will be of some help to you.

The conditioning effect is not good. It is usually caused by insufficient dosage. When it is converted into mud shale, the dehydration performance is reduced. Tests should be carried out to determine the appropriate dry sludge o-phenylenediamine. Dispensing is sometimes due to incorrect dispensing concentration, too high concentration, flocculant is not easy to completely dissolve, although sufficient for measurement, but the modulation effect is not good, sometimes due to the unreasonable location of the dosing point, resulting in too long or too short flocculation time. We should test and adjust the above situation. The belt speed is too high. The belt speed is too large and the mud cake is thin, resulting in a decrease in solid content. The belt speed should be reduced in time, and the thickness of the mud cake should generally be 5-10 mm. The belt tension is too low. This does not guarantee sufficient squeezing force and shearing force. It is to reduce the solid content and the tension should be increased appropriately. The filter cannot filter out the water, it is to reduce the solid content, it should stop running and flush the filter belt.
