Cleaning Steps Of Horizontal Decanter Centrifuge

Cleaning Steps Of Horizontal Decanter Centrifuge

May 15, 2020

The horizontal decanter centrifuge is a spiral discharge sedimentation centrifuge, which is mainly composed of a high-speed rotating drum, a screw conveyor with a hollow rotating shaft and a differential, which are the same as the rotating drum and have a slightly lower speed than the rotating drum The blade on the screw pusher is pushed to the slag discharge port of the small end of the drum to discharge, and the liquid phase overflows through the overflow hole of the big end of the drum. Such continuous circulation in order to achieve the purpose of continuous separation. The principle used by the horizontal spiral centrifuge for the separation of the suspension: the principle of centrifugal sedimentation is used to push the solid phase to the slag discharge port of the small end of the drum through the blade on the screw pusher The liquid phase flows out through the overflow hole at the big end of the drum. In this way, the purpose of continuous separation can be achieved.


The differential in the decanter centrifuge emits abnormal noise during work, which can be avoided. If the differential in the horizontal spiral centrifuge has abnormal noise during operation, it is because the differential has problems. For example, the components of the differential are defective, or it is not installed in place, etc. All will cause the above problems. Therefore, the differential must be checked to avoid the above problems. When the horizontal spiral centrifuge needs cleaning, the centrifuge should be shut down first; then close some corresponding valves, etc. At the same time, open the clean water valve and rinse with clean water for 3 to 5 minutes; then, close the clean water valve and let the centrifuge run Stop again after a while, so that the remaining water in the centrifuge will be discharged automatically. If the water is very clear, then it means that it has been cleaned. If the water is very turbid, it means that it has not been cleaned, and it should be continued until the water is clear.
