Description

Technical Field

[0001] The utility model relates to the technical field of waste oil impurity removal, in particular to a waste oil impurity removal device. Background Art

[0002] With the popularity of automobiles, the use of engine oil will gradually increase. After a certain mileage or time, the engine oil needs to be replaced, so the amount of waste oil will also increase. After a certain period of use, the engine oil deteriorates due to physical and chemical factors, producing organic acids, salts, water, metal chips and other pollutants. The oil products after these pollutants are removed are used in equipment with lower requirements, or further processed to produce base oil.

[0003] Most of the existing waste oil impurity removal equipment has a complex structure. In the process of waste oil recovery, the primary filtration part is very important, but most of the primary filtration uses filtration or sedimentation to remove impurities. The rate at which the waste oil passes through the filter element is slow. Most of them are filtered by free flow by continuous pumping into the treatment box. The waiting time is long and unnecessary, and the replacement of the filter element is not convenient. The treatment box needs to be opened to disassemble the filter element part and its fixing seat, which is more troublesome. The waste oil is divided into larger impurities, smaller impurities, and tiny impurities filtered by the filter element. Larger impurities can easily damage the filter element, and smaller impurities will accumulate on the filter element. Both types of impurities are not convenient to be discharged from the treatment box.

[0004] In the patent document with the publication number CN217312358U, a waste oil impurity removal and filtering device is disclosed, which is filtered through a filter element, and then the filtered oil passes through the waste oil outlet and then enters the first filter tank through the oil outlet pipe for repeated filtering. The secondary filtration of the filter tank is performed, and the oil after filtration and standing can be directly taken out from the fourth filter tank for use. Multiple filtrations can make the oil clearer and cleaner, and more convenient for use.

[0005] However, the waste oil impurity removal and filtering device is not efficient in use, and the equipment is large and the processing method is easy to cause environmental pollution. Therefore, it is necessary to propose a waste oil impurity removal device that can increase the waste oil impurity removal efficiency. Utility Model Content

[0036] Working principle:

[0037] First, the waste oil is poured into the mixing box 1 from the feed inlet 4, and the waste oil is heated and stirred by the heating and stirring mechanism provided inside the mixing box 1. The motor 101 and the heating device are turned on, and the heating tube 105 surrounding the outside of the mixing barrel 104 heats the waste oil inside, while the stirring rod 103 inside it stirs the waste oil, and the front end of the stirring rod 103 can scrape the inner wall of the mixing barrel 104, and at the same time, a neutralizer is added to the feed inlet 4 to neutralize the acid and alkali in the waste oil.

After the waste oil is heated and neutralized, the valve 108 is slowly opened to discharge the waste oil inside the mixing box 1 into the filter box 2 through the discharge pipe 107. First, the waste oil will enter the first filter barrel 301 through the transition pipe 3, and the first filter barrel 301 is provided with a magnet 303, which can adsorb the iron filings inside the waste oil, and then perform preliminary filtration on the waste oil. The filtered waste oil will pass through the filter hole of the first filter barrel 301 and enter the second filter barrel 204.

[0039] Furthermore, after the waste oil enters the second filter barrel 204, the waste oil will be filtered by the second filter barrel 204 and enter the filter box 2 to form a relatively clear oil liquid. The oil liquid inside the filter box 2 can be discharged from the discharge pipe 208 through the control of the valve 209.

[0040] Furthermore, a second motor 202 is provided at the bottom of the filter box 2. After the second motor 202 is started, the second motor 202 will drive the rotating shaft 203 to rotate and then drive the second filter barrel 204 to rotate.

Correspondingly, the first filter barrel 301 inside the second filter barrel 204 will also rotate accordingly. The rotation of the first filter barrel 301 and the second filter barrel 204 will more efficiently throw the waste oil out of the filter barrel.
