Description

Technical Field

[0002] The three-phase centrifuge is a mechanical device that uses centrifugal force to separate solids and liquids, and liquids and liquids. The working principle of the three-phase centrifuge is that after two liquid phases and one solid phase enter the centrifuge, they are expanded thousands of times by the centrifugal field. The solid phase is settled under the action of centrifugal force, and the two liquid phases are also stratified, thereby achieving solid-liquid-liquid three-phase separation, and are discharged from the body separately under the action of special mechanisms. The entire feeding and separation process is completed continuously, closed, and automatically. The three-phase centrifuge is mainly used for clarification or slag and impurity removal of aging oil in oil fields, waste engine oil, and waste grease in catering.

[0003] The existing three-phase centrifuge is generally a horizontal structure. When processing catering waste, the solid waste residue is difficult to discharge because the waste residue after filtering the catering waste is fine and thin. Summary of the invention
