Description

Technical Field

[0001] The utility model relates to the technical field of recycling, in particular to an auxiliary device for recycling waste mineral oil. Background Art

[0002] Waste mineral oil is the oil that is replaced when it cannot be used anymore due to contamination by impurities, oxidation and heat, which changes its original physical and chemical properties. It mainly comes from the sludge and oil footings produced during oil extraction and refining; the sediment produced during the storage of mineral oils; the oil residue and filter media during the replacement and regeneration process of machinery, power, transportation and other equipment.

[0003] In the prior art, for example, the Chinese patent number CN211814279U is a waste mineral oil recycling auxiliary device. At present, when recycling waste mineral oil, it is necessary to filter the impurities in the waste mineral oil. When filtering with a filter cartridge, impurities or ice crystals in the mineral oil often clog the filter screen, causing the waste mineral oil recycling to be interrupted. A waste mineral oil recycling auxiliary device, which comprises: a filter cartridge body and a sealing cover, the sealing cover is buckled on the top of the filter cartridge body, a partition is arranged inside the filter cartridge body, and the internal space of the filter cartridge body is divided into two main oil storage chambers and auxiliary oil storage chambers of different volumes, a filter screen block is connected to the inner wall of the main oil storage chamber, an impurity filter screen is placed above the filter screen block, and a strip overflow hole is opened on the plate surface of the partition plate.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that although it can make the waste mineral oil enter the main oil storage chamber from the oil inlet pipe, filter the impurities in the waste oil through the impurity filter, and the filtered waste mineral oil flows out from the oil outlet pipe at the bottom of the main oil storage chamber, the waste mineral oil naturally flows downward to penetrate the impurity filter to filter the impurities. In this way, the filtration time is relatively long, resulting in a low efficiency of waste mineral oil filtration, and it requires staff to clean the impurities on the impurity filter. This process is time-consuming and laborious, which not only easily makes the staff feel tired, but also leads to a decrease in the efficiency of waste mineral oil recycling. Utility Model Content

In this way, the filtration time is long, resulting in low efficiency of waste mineral oil filtration, and it is necessary for the staff to clean the impurities on the impurity filter screen.
