The reason for the slurry to descend after being dehydrated by the spiral dehydrator

  When installing the spiral dehydrator, pay attention to the choice of weather. Do not install the power line in the sludge treatment equipment during thunderstorm weather. In any case, when installing the components, the power supply must be cut off. Before completing all the work, the power supply should be retrieved.

  Before installation, users should clean or install the appropriate filtration system throughout the circulation system. When installing the equipment, it should be installed on a concrete level and fixed with bolts. Ensure that the body is level and vertical.

  When the spiral dehydrator is powered off, there should be an independent power switch device. It must not be used together with other equipment, otherwise it will cause insufficient voltage and affect the abnormal operation of the equipment and the risk of fire. After the sludge treatment equipment is installed, carefully check if all the accessories are loose. Please loosen the fastening.

  The reasons for the sludge drop after the spiral dehydrator dehydrates: sometimes the dosing is incorrect, the concentration is too high, the flocculant is not completely dissolved, although it can be measured, but the mixing effect is not good. Sometimes the position of the dosing point is unreasonable, resulting in too long or too short flocculation time. The mixing effect is poor. Usually, it is caused by insufficient dosage. When it is converted into shale sludge, the dehydrating performance decreases. Tests should be conducted to determine the appropriate dry sludge p-phenylenediamine. Tests and adjustments should be carried out. The belt speed is too high. The belt speed is too high, the sludge cake is thin, resulting in a decrease in solid content. The belt speed should be reduced promptly. The thickness of the sludge cake should generally be 5-10 millimeters. The belt tension is too small. This does not ensure sufficient extrusion force and shear force, and is to reduce the solid content. The tension should be appropriately increased. The filter cannot filter out water, which is to reduce the solid content. The operation should be stopped and the filter belt flushed.
