Technical Field

[0001] This utility model belongs to the field of lubricating oil recycling technology, and in particular relates to a waste lubricating oil distillation and recycling device. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. Any lubricating oil applied between two relatively moving objects to reduce friction and wear caused by contact is considered lubricating oil. Oil recycling is a measure in the petroleum industry for collecting and managing waste oil generated from equipment lubrication systems. It aims to achieve resource reuse and pollution control, involving the entire process of collection, transportation, storage, utilization, and disposal. Waste oil mainly comes from industrial, transportation, and other industries' oil replacements. Enterprises need to formulate recycling targets and incorporate them into their energy-saving plans. The existing patent publication number CN222729731U discloses a waste lubricating oil distillation and recovery device. Through the distillation stirring mechanism structure, the waste lubricating oil heated at the heating distillation mechanism can be efficiently dispersed, which can effectively improve the overall distillation and recovery efficiency.

The power unit 21 includes: Motor 211 is fixedly mounted on distillation tank 1. The output end of motor 211 is connected to drive shaft 212, and drive shaft 212 is rotatably engaged with distillation tank 1.
