Background technique

In the inspection and maintenance of comprehensive machine equipment in coal mines, according to the factory requirements of the equipment, hydraulic oil, mechanical oil and gear oil are mainly used. New lubricating oil must be added to the overhauled comprehensive machine equipment. Due to the large number of maintenance equipment, it is necessary to A large number of new lubricating oil products are invested, which bears a large maintenance cost. The replaced lubricating oil is treated as waste product. However, during the process of changing the oil, it was found that some of the replaced lubricating oil only contained impurities, and no chemical changes such as emulsification and deterioration occurred. For the purpose of saving materials and reducing costs, some waste lubricating oil has the value of recycling, that is, it is filtered to remove iron particles and solid particles in the waste lubricating oil, and can be reused on related production equipment. Existing waste oil recovery can only be collected, and it needs to be processed again through a special purification treatment device when it is reused, but the pretreatment process can be done simply, and the impurities, metal residues, etc. in the waste oil are separated through the filter device , the existing filtering equipment has complex structure, large floor area, high power consumption, high oil temperature during filtration, easy oxidation, cumbersome treatment process, high waste oil recovery cost, low recovery efficiency, and inconvenient cleaning. It is easy to be attached to the filter net and cause the mesh to be blocked, and the filter device cannot be used. Usually the filter net is welded on the filter tank, which is inconvenient to disassemble and clean.
