A kind of waste lubricating oil recycling treatment method

Abstract

The invention relates to a method for reusing and treating waste lubricating oil. The method for reusing and treating waste lubricating oil adopts the following treatment form. The device includes a bottom stirring device, and the inner thread of the bottom stirring device is sleeved with an outer cylinder. The lubricating oil reuse treatment method, by setting the telescopic stirring device into a telescopic structure, and controlling the expansion and contraction of the second stirring blade under the driving of the telescopic limit rod, when it is necessary to stir the mixed liquid of waste lubricating oil and chemical reagent, The straight rod pushes the telescopic limit rod down, so that the second stirring blade opens and becomes the internal stirring blade, and after the stirring is completed, the straight rod is lifted up, so that the second stirring blade shrinks back, and the four second stirring blades are stirred. Part of the structure of a cylinder with the same diameter as the third connecting column is formed between the leaves, and a continuous external thread groove is formed on the outer wall of the third connecting column and the second stirring blade, so that the filter pressing plate can be uninterrupted during the rotation and downward movement. Improve processing efficiency.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a method for recycling waste lubricating oil. Background technique [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. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention and cleaning buffer. It is made of oil, and some of the used waste lubricating oil is directly discarded, which is not only a waste of resources, but also causes certain pollution to the environment, so now many waste lubricating oil will be recycled. To use, first filter out the large impurities, and then deal with other impurities by other treatment methods, such as sedimentation method, distillation method and chemical treatment. Among them, chemical treatment is mainly by adding to the lubricating oil after preliminary filtering. The chemical r...

Problems solved by technology

[0003] For the chemical treatment method, it is necessary to add chemical reagents to precipitate impurities, so in order to fully integrate and react the chemical reagents and waste lubricating oil, it is necessary to fully stir the mixture of the two. The liquid is stirred and mixed, but it can only be stirred simply by several stirring blades. The liquid is constantly rotating regularly under the drive of the stirring blades, so the mixing effect of the solution is not good, and after the stirring reaction is completed, it cannot be directly in the equipment. The lubricating oil and impurities in the solution after the reaction are quickly separated, but the mixed solution needs to be poured out and placed in a side container for natural sedimentation and stratification. This method is not only very slow and inefficient, but also The container with the solution for sedimentation is also easy to mix the sediment with the oil again when the oil is separated due to the lack of partitions, and the oil separation cannot be achieved well
