Description

Technical Field

[0001] The utility model relates to the field of waste engine oil raw material pretreatment, and relates to a raw material pretreatment device for waste engine oil reprocessing. Background Art

[0002] During the use of the machine, engine oil is needed for auxiliary use, and the waste oil discharged directly into the environment after use will cause serious pollution. At this time, the engine oil needs to be reprocessed so that it can be reused. Before processing, the waste oil needs to be pre-treated to facilitate the subsequent processing process;

[0003] After checking the public (announcement) number: CN215389292U, a waste oil recycling and processing device is disclosed. This technology discloses "including a pretreatment tank, an alkaline substance treatment tank and an acidic substance treatment tank; the pretreatment tank, the alkaline substance treatment tank and the acidic substance treatment tank are all provided with a stirring device, the bottom of the pretreatment tank is provided with a heating device, and the side is connected with a waste oil inlet pipe; a first connecting pipe is provided between the alkaline substance treatment tank and the pretreatment tank, and a strong acid solution inflow pipeline is connected to the side; a second connecting pipe is provided between the acidic substance treatment tank and the alkaline substance treatment tank, and a strong alkaline solution inflow pipeline is connected to the side. The utility model uses the pretreatment tank, the alkaline substance treatment tank and the acidic substance treatment tank to react and remove various impurities in the waste oil, respectively, to obtain a recyclable oil solution";

[0004] In the above-mentioned comparative documents, since the waste oil contains a large amount of metal debris and other impurities caused by friction during the processing of waste oil, these impurities will affect the processing of the oil, and if acid or alkaline substances are used for chemical reaction, on the one hand, the metal material cannot be completely removed, and on the other hand, once the metal impurities are integrated into the oil, they will need to be removed separately later, which is very time-consuming and laborious. If pre-treatment filtration is used for removal, on the one hand, the filtered metal impurities will cause the filter to be blocked during the filtration process, and on the other hand, the filter is generally installed with the filtering instrument by bolts, etc., resulting in the need to disassemble the filter when the impurities on it are collected or blocked, which is time-consuming and laborious.

[0005] In order to solve the above problems, the present application proposes a raw material pretreatment device for waste oil reprocessing. Summary of the invention
