Description

Technical Field

[0001] The utility model relates to the field of lubricating oil filtering, in particular to a lubricating oil filtering device. Background Art

[0002] Lubrication system leakage, poor sealing, long-term heat load of oil, open oil storage and other reasons cause moisture and gas in the air to penetrate into the oil, resulting in water and gas in the lubricating oil. Lubrication system leakage, entry of particulate dust in the air or dust falling off due to system wear, and long-term operation of lubricating oil under high temperature and water content will inevitably cause part of the oil to crack, deteriorate and precipitate colloidal substances. Therefore, the lubricating oil needs to be filtered before use to ensure subsequent use.

[0003] However, since most of the lubricating oil filtration currently on the market directly utilizes the gravity of the lubricating oil itself to filter downward, the filtration efficiency is low. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a lubricating oil filtering device to solve the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: a lubricating oil filtering device, comprising a filter sleeve, an inner side wall of the filter sleeve is installed with a pressed pad, a filtering mechanism is arranged above the pressed pad, the filtering mechanism comprises: a filter cartridge, an upper gasket, and a filter cloth, an outer side array of the filter cartridge is provided with filter holes, a sealing rubber pad is installed on the outer side wall of the upper gasket, a pressure plate is arranged on the outer side of the filter cloth below the upper gasket, an upper cover plate is arranged above the filter sleeve, a scraper is arranged below the upper cover plate and located inside the filtering mechanism, and a brush head is arranged at the outer end of the scraper.

[0006] As a further solution of the utility model: a liquid inlet pipe is installed on one side of the filter sleeve, and a liquid outlet pipe is installed on the other side of the filter sleeve.

[0007] As a further solution of the utility model: a driving motor is installed on the upper surface of the upper cover plate, and a driving shaft is connected between the scraper and the driving motor.

[0008] As a further solution of the utility model: the filter cartridge is clamped with the pressing pad block through the upper gasket, and the pressure plate is connected to the upper gasket by magnetic adsorption.

[0009] As a further solution of the utility model: the filter hole and the filter cartridge are arranged in a through-connected manner, and a storage handle is installed on the upper surface of the upper gasket ring.

[0010] As a further solution of the utility model: the liquid inlet pipe and the liquid outlet pipe are both connected with the filter sleeve, and the upper surface of the upper cover plate is provided with a positioning screw hole.

[0011] As a further solution of the utility model: the upper end of the filter cartridge is arranged obliquely, and the pressed pad is fixedly connected to the filter sleeve.

[0012] As a further solution of the utility model: the drive shaft is fixedly connected to the scraper.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The brush head at the outer end of the scraper will scrape the inner wall of the filter cartridge to scrape off the impurities in the filter holes that may adhere to the filter cartridge. The scraper will be driven to rotate as a whole to stir the lubricating oil in the filter cartridge, thereby increasing the centrifugal force of the lubricating oil, accelerating the flow of the lubricating oil to the outside of the filter cartridge, and increasing the filtration efficiency.

[0015] 2. After the entire filter cloth is fixed and surrounded on the outside of the filter cartridge by the magnetic adsorption of the pressure plate and the upper gasket ring, the outflow of impurities is reduced by the filter cloth on the outside of the filter cartridge.

The filter mechanism 7 includes: a filter cartridge 701, an upper gasket ring 702, and a filter cloth 707. The upper end of the filter cartridge 701 is inclined, and a storage handle 703 is installed on the upper surface of the upper gasket ring 702. The filter cartridge 701 is connected to the press-fitting pad through the upper gasket ring 702. 101 is snap-fitted, filter holes 705 are arranged in an outer array of the filter cartridge 701, the filter holes 705 are connected with the filter cartridge 701, a sealing rubber pad 704 is installed on the outer wall of the upper gasket 702, a pressure plate 706 is arranged on the outer side of the filter cloth 707 below the upper gasket 702, the pressure plate 706 is connected with the upper gasket 702 by magnetic adsorption, an upper cover plate 4 is arranged above the filter sleeve 1, a scraper 5 is arranged inside the filter mechanism 7 below the upper cover plate 4, and a brush head 501 is arranged on the outer end of the scraper 5.

[0024] like Figure 2-5 As shown, in this embodiment, a liquid inlet pipe 2 is installed on one side of the filter sleeve 1, and a liquid outlet pipe 3 is installed on the other side of the filter sleeve 1. The liquid inlet pipe 2 and the liquid outlet pipe 3 are both connected with the filter sleeve 1. A drive motor 6 is installed on the upper surface of the upper cover plate 4.

[0025] The working principle of the utility model is as follows: when in use, after the filter cloth 707 is sleeved on the outside of the filter cartridge 701 as a whole, the pressing plate 706 is passed through the outside of the filter cloth 707 as a whole and then placed and adsorbed on the lower surface of the upper gasket ring 702.
