Problems solved by technology

[0006] Existing, in the process of screening the metal chips contained in the waste engine oil, a filter screen is used for filtering and screening, and the filtering and screening will make the metal chips contained in the waste engine oil and the rust debris precipitate and mix together, and the metal chips can be reused. Processing and use, and the mixing of rust and metal shavings will accelerate the oxidation speed of metal shavings in the later stage and affect the reprocessing of metal shavings

Embodiment 1

[0042] see figure 1 , figure 2 , image 3 and Figure 6 , is a schematic diagram of the overall structure of a waste engine oil recovery and reuse treatment method. The waste engine oil recovery and reuse treatment method screens and filters the iron filings and metal filings contained in the waste engine oil, so that the waste engine oil can be recycled and reused. Specifically , the processing method includes the following steps:

[0043] S1, waste oil concentration, collect a large amount of waste engine oil in one oil pool;

[0044] S2, stirring the oil, stirring the waste engine oil stored in the oil pool in step S1 to make the viscous waste engine oil thinner;

[0045] S3, screening metal filings, screening the waste engine oil stirred in step S2, so that the metal filings in the waste engine oil are separated from the oil pool;

[0046] S4, filter iron filings, discharge the waste engine oil in the oil pool, filter the iron filings contained in the waste engine oi...

Embodiment 2

[0058] see Figure 1-6 , is a schematic diagram of the overall structure of a waste engine oil recovery and reuse treatment method. This embodiment has similarities with the above-mentioned embodiment 1, and the similarities will not be described in this embodiment. The specific differences are:

[0059] The top of each stirring bar 10 is all provided with the magnetic block 102 of square block, and the inside of magnetic block 102 is provided with square hole 103, is embedded with square block-shaped magnetic block 104 in the hole of square hole 103, and magnetic block 104 The volume of the square hole 103 is 1 / 2, and the two sides of the bottom end of the magnetic block 104 are provided with symmetrical hypotenuses 108;

[0060] In the middle of the square hole 103 and on both sides of the hole wall of the square hole 103, there are V-shaped metal sheets 106 matched with the hypotenuse 108, and the bottom ends of the V-shaped metal sheets 106 on each side are symmetrically p...

Abstract

The invention discloses a waste engine oil recycling treatment method, and relates to the technical field of engine oil recovery processing. The method comprises the following steps of S1, centralizing and collecting a large amount of waste engine oil uniformly in an engine oil pool; S2, stirring the waste engine oil stored in the engine oil pool in the step S1, and enabling the viscous waste engine oil to be movably diluted; S3, screening the waste engine oil stirred in the step S2 to separate the metal chips in the waste engine oil from the engine oil pool; and S4, discharging the waste engine oil in the engine oil pool, filtering the scrap iron contained in the waste engine oil through a filter screen to separate the scrap iron from the waste engine oil. According to the present invention, a cylindrical stirring cylinder is installed at the axis position in an engine oil pool cavity, a stirring rod is arranged on the outer wall of the stirring cylinder, and the metal scrap iron of the waste engine oil is adsorbed through a magnetic block at the top end of the stirring rod, so that the metal scrap iron is separated from the waste engine oil in the engine oil pool cavity, and themetal scrap iron is prevented from being precipitated and mixed with the rust chips.

Description

technical field [0001] The invention relates to the technical field of oil recovery and processing, in particular to a method for recycling and reusing waste engine oil. Background technique [0002] Waste engine oil refers to the impurities such as water, dust, other miscellaneous oils and metal powder produced by the wear and tear of the engine oil during use, resulting in blackening of the color, increase in viscosity, gradual deterioration of the engine oil, and formation of organic acids and colloids. and asphalt-like substances. [0003] The regeneration of waste engine oil is to remove impurities in the oil by sedimentation, distillation, pickling, alkali washing, filtration and other methods. It is a toxic substance and belongs to the solid hazardous waste marked by the state. It is strictly forbidden to buy and sell waste engine oil at will, and it should be handled by a qualified waste oil treatment company. [0004] Existing patent No. CN201710589304.X discloses...
