Description

Technical Field

[0001] The utility model relates to the technical field of waste oil recovery, in particular to a pretreatment device for waste oil recovery. Background Art

[0002] Waste oil is the oil that is replaced when it cannot be used anymore due to the change of its original physical and chemical properties due to contamination by impurities, oxidation and heat. It is the replacement oil generated due to the deterioration of lubricating oil performance caused by oxidation and mechanical friction of machinery, power, transportation and other equipment. The pretreatment device in waste oil recovery is used for waste oil filtration.

[0003] A Chinese patent discloses a pretreatment device for waste oil recovery (authorization announcement number CN216149220U). The patented technology can conveniently clean and collect the floating debris of waste oil in the sedimentation tank and remove it from the sedimentation tank by setting a lead screw, a movable nut, an electric telescopic rod, a pull rod, a first filter plate, a drive motor and a second filter plate, thereby improving the efficiency of sedimentation tank pretreatment. However, the above-mentioned pretreatment device for waste oil recovery filters the solid matter in the waste oil by salvaging, and the salvage speed is slow, which is not conducive to the treatment efficiency of the waste oil.
