Problems solved by technology

[0004] (1) Most of the existing waste engine oil recovery equipment first passes through the sedimentation tank for precipitation, and then extracts and filters the waste engine oil after the precipitation is completed, so as to remove metal debris and granular impurities in the waste engine oil, and then use other waste engine oil for recovery The equipment further processes the precipitated waste engine oil, and the oil transfer process is cumbersome;
[0005] (2) When the existing waste engine oil recovery equipment recycles waste engine oil, the bottom of the sedimentation tank needs to be cleaned manually after a period of use. Intermittent, and waste engine oil is not sorted when processing waste engine oil, thereby reducing the recycling rate of waste engine oil

Embodiment Construction

[0036] In order to make the technical means realized by the present invention, creative features, goals and effects easy to understand, the following combination Figure 1 to Figure 6 , to further elaborate the present invention.

[0037] A method for recycling waste engine oil, the specific recycling method is as follows:

[0038] S1. Feeding: adding waste engine oil into the sedimentation tank 2 manually, and allowing the waste engine oil to settle in the sedimentation tank 2, so that the waste engine oil is separated into layers;

[0039] S2. Stratified treatment: the settled waste engine oil is divided into different layers, and the waste engine oil of different layers is treated separately. The specific steps are as follows:

[0040] a: Oil absorption: manually loosen the tightening hand wheel 313 through the glass at the front end of the pool body 21, so that the U-shaped mounting plate 312 drives the oil suction pump head 33 down to the oil layer, and manually fix the ...

Abstract

The invention relates to a waste engine oil recovery and treatment method. An apparatus for realizing the method comprises a mounting table, a sedimentation tank, a layered oil suction device, a filtering device and a rotary deslagging device, the sedimentation tank, is welded to the middle part of the upper end of the mounting table, the layered oil suction device is mounted at the rear side of the sedimentation tank, the filtering device is arranged at the rear end of the layered oil suction device and welded to the middle part of the upper end of the mounting table, and the rotary deslagging device is mounted at the lower end in the sedimentation tank,. The waste engine oil recovery and treatment method can solve the problem of tedious waste engine oil recovery process of existing wasteengine oil recovery apparatuses due to filtration carried out after settlement and the problem of reduction of the waste engine oil recycling rate due to manual regular cleaning of a tank bottom andclassification treatment of the waste machine oil.

Description

technical field [0001] The invention relates to the field of recycling waste engine oil, in particular to a method for recycling and treating waste engine oil. Background technique [0002] Waste engine oil means that the engine oil is mixed with impurities such as water, dust, other miscellaneous oils and metal powder produced by machine wear during use, resulting in blackening of the color and increase in viscosity. The second is that the oil gradually deteriorates, forming organic acids, colloids and asphalt-like substances. The regeneration of waste engine oil is to remove impurities in the oil by sedimentation, distillation, pickling, alkali washing, filtration and other methods. If such waste oil is not properly treated and leaks or is discharged randomly, it will have a serious impact on the surrounding environment. Recycling waste engine oil is conducive to resource recycling and environmental protection. [0003] At present, when recycling waste engine oil, the fo...
