Separation principle and cleaning steps of horizontal spiral centrifuge

Horizontal spiral centrifuge is a kind of spiral discharge sedimentation centrifuge. It is mainly composed of a high-speed drum, a screw conveyor with a hollow shaft and a differential mechanism with the same rotating direction as the drum, and the rotating speed is slightly lower than that of the drum. The blade on the screw pusher is pushed to the slag discharge port at the small end of the drum for discharge, and the liquid phase overflows through the overflow hole at the large end of the drum. In order to achieve the purpose of continuous separation.

The principle adopted by horizontal spiral centrifuge to separate drilling suspension: the principle of centrifugal sedimentation is adopted. The solid phase is pushed to the slag discharge port at the small end of the drum through the blade on the screw pusher, and the liquid phase flows out through the overflow hole at the large end of the drum. In this way, continuous separation can be achieved.

The differential in horizontal spiral centrifuge makes abnormal noise during working, which can be avoided. If the differential in the horizontal spiral centrifuge has abnormal noise during the working process, it is the differential that has problems. For example, the parts of the differential have problems, or they are not installed in place, which will lead to the above problems. Therefore, to check the differential to avoid the above problems.

When the horizontal spiral centrifuge needs to be cleaned, the centrifuge should be shut down first; then, some corresponding valves should be closed; at the same time, the clean water valve should be opened and washed with clean water for 3 to 5 minutes; then, the clean water valve should be closed to let the centrifuge run for a while and then shut down. In this way, the residual 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 muddy, it means that it has not been cleaned, and it should be continued until the water is clear.

The material type, sealing ring, gasket material, surface treatment measures and filter cloth material of horizontal screw separator shall be determined during the selection. The nature of the material can be informed to the manufacturer during the selection, so that the manufacturer can put forward suggestions on the material selection of horizontal screw centrifuge according to the characteristics of the separated medium, and indicate in the order, so as to ensure the anti-corrosion requirements of the centrifuge 。

If there are flammable and explosive substances such as organic solvents in the materials or environment processed by horizontal screw centrifuge, the centrifuge shall have explosion-proof performance, and the explosion-proof performance shall be determined according to the explosion-proof requirements of the process. In terms of machinery, electronic control and accessories configuration, various measures should be taken, such as explosion-proof isolation barrier, non-contact energy consumption braking system, electrostatic grounding, explosion-proof automatic control; explosion-proof motor, explosion-proof lighting, anti-collision measures, anti-static drive belt; nitrogen protection device, nitrogen online detection, on-site explosion-proof control button.
