[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering.

[0003] Bag filter is a multi-purpose filtering equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, closed working and strong adaptability. Bag filter is used in the filtration of base oil of lubricating oil, filtration of synthetic lubricating oil and fine filtration of lubricating oil. Bag filter is widely used in the production and processing of lubricating oil.

[0004] During the production and processing of lubricating oil, bag filters can filter out impurities in the lubricating oil and improve the quality of the lubricating oil. However, during the long period of impurity removal, the filter screen in the filter will be gradually clogged by impurities. If it is not cleaned in time, it will not only affect the production and processing efficiency of the lubricating oil, but also easily cause excessive pressure difference between the inside and outside of the filter screen in the filter, causing equipment damage.

[0005] When cleaning the filter screen of the existing filter machine, the equipment needs to be shut down, the filter screen needs to be removed and replaced, or the filter screen needs to be removed and rinsed before being installed and used. Although the filter screen can be cleaned and the filter machine can continue to work, the maintenance and replacement time is long, which affects the production and processing efficiency of the lubricating oil; and the installation and disassembly of the filter screen increases the labor intensity of the staff.

[0029] Working principle of the utility model: when processing lubricating oil, firstly connect the equipment to electricity and connect it to the external PLC control unit, the lubricating oil is input from the feed pipe 13, enters the feed chamber 16 of the shell 1, the lubricating oil enters the filter cartridge 5, is filtered by the filter screen 56, enters the discharge chamber 17, and then passes through the discharge pipe 14 and is discharged from the shell 1, completing the first impurity removal processing of the lubricating oil, extracts the lubricating oil at the discharge pipe 14 for testing, if the tested product is qualified, it is stored, if not qualified, it is input from the feed pipe 13 to the shell 1, and is subjected to impurity removal processing again until it is qualified; When impurities in the lubricating oil are intercepted by the filter 56, the impurities adhere to the filter 56. As the processing time increases, The mesh holes on the filter screen 56 are gradually blocked, and a pressure difference occurs between the feed chamber 16 and the discharge chamber 17. The pressure in the feed chamber 16 gradually increases. Since the sliding chamber is a closed chamber, when the impurity removal equipment is not working, the pressure is consistent with the pressure in the feed chamber 16. However, as the pressure in the feed chamber 16 increases, the pressure plate 534 is pushed to slide in the brush plate 531 under the action of pressure, and the space of the closed chamber is reduced, so that the pressure in the closed chamber is consistent with that in the feed chamber 16. When the pressure plate 534 slides, it drives the connecting rod 535 to slide on the mounting plate 533, and the spring 536 is compressed, and at the same time, the brush plate 531 is pushed to slide in the plate frame 532, so that the bristles on the brush plate 531 contact with the mounting frame 51 in the filter cartridge 5 and bend the bristles. As the pressure in the feed chamber 16 increases, the pressure sensor 3 on the head 12 transmits the pressure signal to the PLC control unit, and the PLC control unit controls the drive component 4 to work and clean the filter screen 56 in the filter cartridge 5. The hydraulic cylinder 41 is controlled to work and contract, driving the motor 42 and the connecting plate 43 to move downward, and at the same time driving the waste pipe 6 to move downward. An oil seal is arranged between the waste pipe 6 and the waste collecting bucket 55, so that oil leakage will not occur, and at the same time, the sliding and rotation of the waste pipe 6 will not be affected. When the waste pipe 6 moves downward, the cleaning rod 7 is driven to move downward. Since the cleaning portion 72 of the cleaning rod 7 is in contact with the inner wall of the waste collecting bucket 55 and cannot move downward, the cleaning portion 72 and the clamping portion 71 are rotated with the connection between the cleaning portion 72 and the hinged portion 73 as the fulcrum, and the torsion between the hinged portion 73 and the waste pipe 6 is The spring accumulates force, and at the same time, the cleaning portion 72 is no longer in contact with the inner wall of the waste collecting bucket 55, so that the clamping portion 71 is embedded in the groove 57 on the lower ring plate 54, the hydraulic cylinder 41 stops working, and the motor 42 is controlled to work and rotate, and the waste discharge pipe 6 is driven to rotate through the gear set 44, so that the cleaning plate 53 is driven to rotate through the cleaning rod 7 and the lower ring plate 54. Under the action of the inclined brush hairs, not only the impurities adhering to the filter screen 56 are brushed, but also the impurities are gathered to the waste collecting bucket 55, so that the filter screen 56 can be cleaned without stopping the operation of the impurity removal equipment, so that the impurity removal equipment can continue to work; When the filter screen 56 is cleaned, as the pressure on both sides of the filter cartridge 5 is gradually balanced, the brush plate 531 retracts into the plate frame 532, the pressure plate 534 is reset under the action of the spring 536 and the pressure in the sealed chamber, the cleaning plate 53 is reset under the drive of the drive assembly 4, the hydraulic cylinder 41 is controlled to work and extend, and the cleaning rod 7 is driven to reset under the elastic force of the torsion spring, so that the cleaning portion 72 fits the inner wall of the waste collecting bucket 55; After cleaning the filter cartridge 5 for many times, impurities accumulate in the waste collecting bucket 55 and need to be removed. At this time, the impurity removal equipment is controlled to stop running, the lubricating oil in the equipment is completely discharged from the discharge pipe 14, and the valve at the bottom of the waste discharge pipe 6 is opened. The impurities in the waste collecting bucket 55 are discharged along the waste discharge pipe 6, but some impurities still adhere to the inner wall of the waste collecting bucket 55. At this time, the motor 42 is controlled to work and rotate, driving the waste discharge pipe 6 to rotate, thereby driving the cleaning part 72 in the cleaning rod 7 to scrape and clean the inner wall of the waste collecting bucket 55, and the cleaning part 72 is inclined. While scraping, the impurities are pushed downward and discharged from the waste discharge pipe 6, completing the discharge and cleaning of the impurities.
