Description

[Technical field]

[0001] The invention relates to the field of filters, in particular to a self-cleaning filter. [Background technology]

[0002] The function of the filter in a diesel vehicle is to filter out harmful impurities and moisture in the fuel system, protect the normal operation of the engine, reduce wear, avoid blockage, and increase engine life. The oil generally passes through two stages of filters from the vehicle's fuel tank to the oil pump and high-pressure rail supply system. At present, after the diesel is filtered by the filter, large particles of impurities in the diesel adhere to the surface of the filter cartridge, blocking the filter holes on the filter cartridge, seriously affecting the filtering effect.

[0003] The present invention is proposed in view of the deficiencies in the prior art. [Summary of the invention]

[0004] The object of the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a self-cleaning filter.

[0005] The present invention can be implemented by the following technical solutions:

[0006] The present invention discloses a self-cleaning filter, comprising an outer shell, on which an oil outlet pipe and an oil inlet pipe are fixed, a support plate is also fixed inside the outer shell, a plurality of filter cartridges rotatably connected to the support plate are evenly arranged on the support plate, a plurality of bristles are evenly fixed on the surface of the filter cartridge, a filter tube is fixed inside the filter cartridge, the bottom of the filter tube passes through the support plate and is rotatably connected to the support plate, and a plurality of fan blades are also fixed at the bottom of the filter tube. Due to the action of the oil pump, the oil enters the outer shell through the oil inlet pipe, and after being filtered by each filter cartridge, the oil enters the outer shell under the support plate through the filter tube and is discharged through the oil outlet pipe for use. When the oil enters under the support plate through the filter tube, when the oil passes through the fan blade position inside the filter tube, due to the curved surface structure of the fan blade, when the oil passes through the fan blade, the fan blade drives the filter tube to rotate, the filter cartridge rotates with the filter tube, and the bristles on the surface of the filter cartridge rotate with the filter cartridge. Since the bristles between two adjacent filter cartridges are in contact with each other, when the bristles rotate with the filter cartridge, the adjacent filter cartridge surfaces are brushed by the bristles, which can effectively prevent large particles of impurities from adhering to the surface of the filter cartridge. The large particles of impurities are brushed by the bristles and settle to the surface of the support plate, which can effectively extend the service life of the filter.

[0007] Preferably, support rings are fixed on the support plate at positions corresponding to the filter tube, and the filter tube is connected to the support rings via a sealing bearing. The filter tube is connected and fixed to the support rings via the sealing bearing, which can effectively prevent impurities from entering the oil outlet pipe through the support plate.

[0008] Preferably, a positioning plate is fixed in the outer shell above the filter cartridge, positioning seats are fixed at corresponding positions of the positioning plate and the filter tube, and the top of the filter tube is connected to the positioning seat via a sealing bearing.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] The bristles between two adjacent filter cartridges are in contact with each other. When the bristles rotate with the filter cartridges, the bristles brush the surfaces of the adjacent filter cartridges, which can effectively prevent large particles of impurities from adhering to the surface of the filter cartridges. The large particles of impurities are brushed by the bristles and settle on the surface of the support plate, which can effectively extend the service life of the filter.

Brief Description of the Drawings

[0011] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings, wherein:

[0015] In the figure: 1, housing; 2, oil outlet pipe; 3, oil inlet pipe; 4, support plate; 5, support ring; 6, filter tube; 7, filter cartridge; 8, brush; 9, positioning plate; 10, positioning seat; 11, fan blade; [Specific implementation method]

[0016] The embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0017] like Figures 1 to 3As shown, the present invention discloses a self-cleaning filter, including an outer shell 1, an oil outlet pipe 2 and an oil inlet pipe 3 are fixed on the outer shell 1, a support plate 4 is also fixed in the outer shell 1, a plurality of filter cartridges 7 rotatably connected to the support plate 4 are evenly arranged on the support plate 4, a plurality of bristles 8 are evenly fixed on the surface of the filter cartridge 7, a filter tube 6 is fixed inside the filter cartridge 7, the bottom of the filter tube 6 passes through the support plate 4 and is rotatably connected to the support plate 4, and a plurality of fan blades 11 are also fixed to the bottom of the filter tube 6. Due to the action of the oil pump, the oil enters the outer shell 1 through the oil inlet pipe 3, and after being filtered by each filter cartridge 7, the oil enters the outer shell 1 below the support plate 4 through the filter tube 6 and is discharged through the oil outlet pipe 2 for use. When the oil enters below the support plate 4 through the filter tube 6, when the oil passes through the fan blade 11 inside the filter tube 6, due to the curved surface structure of the fan blade 11, when the oil passes through the fan blade 11, the fan blade 11 drives the filter tube 6 to rotate, the filter cartridge 7 rotates with the filter tube 6, and the bristles 8 on the surface of the filter cartridge 7 rotate with the filter cartridge 7. Since the bristles 8 between two adjacent filter cartridges 7 are in contact with each other, when the bristles 8 rotate with the filter cartridge 7, the adjacent filter cartridge 7 surfaces are brushed by the bristles 8, which can effectively prevent large particles of impurities from adhering to the surface of the filter cartridge 7. After being brushed by the bristles 8, the large particles of impurities settle to the surface of the support plate 4, which can effectively extend the service life of the filter.

[0018] Among them, support rings 5 ​​are fixed on the support plate 4 at positions corresponding to the filter tube 6, and the filter tube 6 is connected to the support ring 5 through a sealing bearing. The filter tube 6 is connected and fixed to the support ring 5 through the sealing bearing, which can effectively prevent impurities from entering the oil outlet pipe 2 through the support plate 4.

[0019] A positioning plate 9 is fixed in the housing 1 above the filter cartridge 7, and positioning seats 10 are fixed at corresponding positions of the positioning plate 9 and the filter tube 6, and the top of the filter tube 6 is connected to the positioning seat 10 through a sealing bearing.

[0020] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention. These changes, modifications, substitutions and variations should also be regarded as the scope of protection of the present invention.
