Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and in particular relates to an anti-clogging engine oil filter. Background Art

[0002] With the rapid development of the automobile industry, the oil filter is a key component of the engine lubrication system, and its performance directly affects the engine's operating efficiency and service life. The main function of the oil filter is to filter out impurities that enter the engine lubrication system, such as metal chips, dust and other solid particles, to ensure the cleanliness of the oil, reduce engine wear and extend the engine life. However, in cold environments, the viscosity of the oil increases and the fluidity deteriorates, resulting in more stringent working conditions for the oil filter, and the filter element is more likely to be blocked due to the accumulation of impurities, which in turn affects the normal circulation of the oil and the heat exchange of the engine.

[0003] Traditional oil filters usually use disposable paper filter elements or synthetic fiber filter elements. Although these filter elements can meet the filtering needs to a certain extent, in low temperature environments, the oil becomes viscous, which seriously affects the filtering efficiency of the filter element. In addition, when the engine needs to be maintained, the oil filter needs to be replaced as a whole, resulting in a waste of resources and an increase in economic costs. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an anti-clogging oil filter, which can filter out iron and impurities in the oil and heat the oil after filtering, thereby reducing wear on the engine and reducing resource waste and economic costs during maintenance.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anti-clogging oil filter comprises a shell, a sealing cover is fixedly mounted on the top of the shell, a plurality of first oil inlet holes distributed in an annular shape are opened inside the sealing cover, and an oil outlet pipe is fixedly connected to the bottom of the sealing cover;

[0007] A chip removal component is fixedly installed on the inner wall of the sealing cover, and the chip removal component is used to remove iron chips in the engine oil;

[0008] A heating ring is fixedly installed inside the housing, and the heating ring is used to heat the engine oil to reduce the viscosity of the engine oil;

[0009] A glass fiber filter cartridge is fixedly installed inside the housing. The glass fiber filter cartridge is used to filter impurities in the engine oil. The glass fiber filter cartridge itself has the advantages of high temperature resistance and high hardness.

[0010] Furthermore, the chip removal assembly includes a fixing ring fixedly mounted on the inner wall of the sealing cover and a plurality of magnets distributed in a ring shape inside the fixing ring.

[0011] Furthermore, a support plate is fixedly connected to the inner wall of the shell, and the support plate is located at the bottom of the glass fiber filter cartridge. A plurality of second feed holes distributed in an annular shape are opened inside the support plate.

[0012] Furthermore, a second threaded joint is provided on the top of the support plate, and a thread corresponding to the second threaded joint is provided on the inner wall of the oil outlet pipe.

[0013] Furthermore, a sealing baffle is fixedly connected to the outer wall of the sealing cover, and the sealing baffle is located on the outer wall of the shell.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] First, after the engine oil enters from the first oil inlet, the iron filings in the oil are first attracted by the magnet, so that the iron filings can be removed before filtering impurities to prevent them from causing blockage and affecting the filtering effect. Then the engine oil moves downward and the impurities in the oil are filtered out through the glass fiber filter cartridge. Compared with traditional paper filter cartridges, glass fiber filter cartridges have good high temperature resistance, which can prevent high temperature oil from softening the filter cartridge and affecting the filtering effect. At the same time, the glass fiber filter cartridge has a higher hardness and a longer service life than traditional paper filter cartridges.

[0016] Secondly, in order to avoid the problem of increasing the viscosity of the engine oil in low temperature weather, affecting the fluidity of the engine oil and thus increasing engine wear, after the oil is filtered, the oil is heated by a heating ring to reduce the viscosity of the oil, and then discharged into the engine, which can speed up the oil preheating and increase the service life of the engine.

[0017] In addition, when the engine needs maintenance, the sealing cover can be removed, and then a new glass fiber filter cartridge can be replaced, and then the iron filings in the magnet can be cleaned, which can reduce waste of resources and reduce economic costs.
