Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and more specifically, to a high-efficiency differential-speed centrifuge device. Background Technology

[0002] A horizontal screw centrifuge is a commonly used wastewater solid-liquid separation device. Its main principle is to use centrifugal force to separate solid and liquid phases in the wastewater, and then use a screw conveyor mechanism to discharge the solid and liquid phases from different outlets, achieving solid-liquid separation. When the solid particles in the wastewater are small, flocculants need to be added to the wastewater to agglomerate the solids and improve the stratification effect. Currently, most centrifuges use grease-lubricated bearings. While this provides lubrication, grease-lubricated bearings have drawbacks such as poor load-bearing capacity and short service life. A more efficient differential-speed centrifuge device is needed to solve this problem. Utility Model Content
