Description

Technical Field

[0001] This application relates to the technical field of filtration devices, and particularly to a combined water-absorbing filter element. Background Art

[0002] Engine oil, that is, engine lubricating oil. Engine oil can play roles such as lubricating and reducing friction, assisting in cooling and temperature reduction, sealing and preventing leakage, rust and corrosion prevention, and shock absorption and buffering for the engine. During the use of engine oil, it is easy to mix with solid impurities and moisture, thus affecting the operation of mechanical equipment. In order to ensure the normal operation of the engine, it is generally necessary to replace the engine oil regularly.

[0003] In order to extend the service life of engine oil, currently, generally an oil separator is used to separate solid impurities and moisture in the engine lubricating oil, so as to achieve the purpose of extending the service life of the machine. However, after the water in the engine oil is separated by the oil separator, there is still a small amount of water in the engine oil, which may affect the operation of the engine. Utility Model Content

[0004] In order to facilitate reducing the moisture inside the engine lubricating oil, this application provides a combined water-absorbing filter element.

[0005] The combined water-absorbing filter element provided by this application adopts the following technical solution:

[0006] A combined water-absorbing filter element includes a combined filter element, and the combined filter element is made of a hydrophilic and oleophobic material.

[0007] The combined filter element is placed inside a filter cylinder, and the filter cylinder and the combined filter element form a filtration assembly.

[0008] The filtration assembly is placed inside an oil tank, and the oil tank is used for storing engine lubricating oil.

[0009] A negative-pressure water removal assembly is connected to the filter cylinder.

[0010] Place the filtration assembly inside an oil tank filled with engine lubricating oil. The filter cylinder supports and fixes the combined filter element. When the engine lubricating oil flows, it contacts the filtration assembly. Since the combined filter element is made of a hydrophilic and oleophobic material, the combined filter element blocks the engine lubricating oil inside the oil tank and adsorbs and collects the moisture inside the engine lubricating oil. Then, the negative-pressure water removal assembly pumps out the moisture collected by the combined filter element, facilitating the recycling of the combined filter element.

[0011] Optionally, the filter cartridge includes a water inlet cylinder, a water outlet cylinder located inside the water inlet cylinder, an upper end cap installed on the top of the water inlet cylinder, and a lower end cap installed on the bottom of the water inlet cylinder. The upper end cap, the lower end cap, the water inlet cylinder, and the water outlet cylinder form a placement cavity, and the combined filter element is placed inside the placement cavity. A plurality of water inlet holes are formed on the cylinder wall of the water inlet cylinder, a plurality of water outlet holes are formed on the cylinder wall of the water outlet cylinder, and the negative pressure water removal assembly communicates with the inside of the water outlet cylinder.

[0012] Optionally, the combined filter element includes a filter residue member installed inside the placement cavity and a water absorption member installed inside the filter residue member.

[0013] Optionally, the filter residue member includes an outer filter layer installed on the inner wall of the water inlet cylinder, an inner filter layer installed on the outer wall of the water outlet cylinder, an upper filter layer installed on the top of the outer filter layer, and a lower filter layer installed on the bottom of the outer filter layer. The outer filter layer, the inner filter layer, the upper filter layer, and the lower filter layer form a filtering space, and the water absorption member is placed in the filtering space.

[0014] Optionally, the water absorption member includes a water absorption layer and an extrusion layer alternately arranged inside the filtering space along the axial direction of the water outlet cylinder, and both the water absorption layer and the extrusion layer are made of hydrophilic and oleophobic materials.

[0015] Optionally, the water absorption layer includes a plurality of water absorption particles, and the plurality of water absorption particles are laid flat between two adjacent extrusion layers.

[0016] Optionally, the extrusion layer includes a plurality of water absorption thin sheets installed between two adjacent water absorption layers, and the plurality of water absorption thin sheets are stacked along the axial direction of the water outlet cylinder.

[0017] Optionally, the negative pressure water removal assembly includes a water suction pipe and a vacuum adsorption pump. The water suction pipe penetrates through the tank wall of the fuel tank in a sealed manner. One end of the water suction pipe communicates with the filter cartridge, and the other end of the water suction pipe communicates with the vacuum adsorption pump.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. Place the filtering assembly inside the fuel tank filled with engine lubricating oil, support and fix the combined filter element through the filter cartridge. The engine lubricating oil contacts the filtering assembly during the flowing process. Since the combined filter element is made of hydrophilic and oleophobic materials, the combined filter element blocks the engine lubricating oil inside the fuel tank and adsorbs and collects the moisture inside the engine lubricating oil, reducing the moisture in the engine lubricating oil. Then, the water stored inside the combined filter element is pumped out through the negative pressure water removal assembly, facilitating the recycling of the combined filter element;

[0020] 2. When absorbing the moisture inside the engine lubricating oil through the combined filter element, the water absorption layer and the extrusion layer absorb the moisture in the engine lubricating oil and block the engine lubricating oil, reducing the moisture in the engine lubricating oil and at the same time reducing the possibility of the engine lubricating oil entering the interior of the water outlet cylinder through the water outlet holes on the water outlet cylinder;

[0021] 3. The water absorption particles are pressed tightly by the water absorption thin sheet, reducing the possibility of the water absorption particles moving and causing the engine lubricating oil to enter the water outlet cylinder. At the same time, after the water absorption thin sheet absorbs water and swells, the possibility of the water absorption particles moving is further reduced, and the possibility of the engine lubricating oil entering the water outlet cylinder is further reduced.

[0028] The following will Figures 1-4 further describe the present application in detail with reference to the attached

[0029] An embodiment of the present application discloses a combined water absorption filter element.

[0030] A combined water absorption filter element includes a combined filter element. The combined filter element is made of a hydrophilic and oleophobic material. The combined filter element is placed inside a filter cylinder. The filter cylinder and the combined filter element form a filtering assembly. The filtering assembly is placed inside a fuel tank. The fuel tank is used to store engine lubricating oil; a negative pressure water removal assembly is connected to the filter cylinder.

[0031] During the process of the engine lubricating oil flowing inside the fuel tank, the engine lubricating oil inside the fuel tank comes into contact with the filtering component, and the filtering component absorbs and stores the moisture inside the engine lubricating oil, thereby reducing the water content inside the engine lubricating oil. Then, the water inside the filtering component is regularly pumped out through the negative pressure water removal component to reduce the moisture inside the filtering component, thereby enhancing the service life of the filtering component.

[0032] The filtering component includes a filter cartridge 1 and a combined filter element 2.

[0033] The filter cartridge 1 includes a water inlet cylinder 11, a water outlet cylinder 12, an upper end cover 13 and a lower end cover 14. A plurality of water inlet holes 111 are formed on the water inlet cylinder 11. The water outlet cylinder 12 is located inside the water inlet cylinder 11, and the water inlet cylinder 11 and the water outlet cylinder 12 are coaxially arranged. A plurality of water outlet holes 121 are formed on the cylinder wall of the water outlet cylinder 12. The upper end cover 13 is located at the top of the water inlet cylinder 11, the lower end cover 14 is located at the bottom of the water inlet cylinder 11, and both the upper end cover 13 and the lower end cover 14 are coaxially arranged with the water inlet cylinder 11. An annular placement space is formed between the water inlet cylinder 11, the water outlet cylinder 12, the upper end cover 13 and the lower end cover 14.

[0034] The combined filter element 2 includes a filter residue part 21 and a water absorption part 22.

[0035] The filter residue part 21 includes an outer filter layer, an inner filter layer, an upper filter layer and a lower filter layer. The outer filter layer is annularly arranged and fixedly installed on the inner wall of the water inlet cylinder 11. The inner filter layer is annularly arranged and fixedly installed on the outer wall of the water outlet cylinder 12. The upper filter layer is fixedly installed on the top of the outer filter layer and fixedly connected to the bottom of the upper end cover 13. The lower filter layer is fixedly installed on the bottom of the outer filter layer and fixedly connected to the top of the lower end cover 14. The outer filter layer, the inner filter layer, the upper filter layer and the lower filter layer form an annular filtering space for filtering solid impurities in the engine lubricating oil. In the embodiment of the present application, the outer filter layer, the inner filter layer, the upper filter layer and the lower filter layer are all non-woven fabrics made of hydrophilic and oleophobic materials.

[0036] The water absorption part 22 is located inside the filtering space. The water absorption part 22 includes a water absorption layer 221 and an extrusion layer 222, and the water absorption layer 221 and the extrusion layer 222 are alternately distributed along the axis direction of the water outlet cylinder 12. The water absorption layer 221 includes a plurality of water absorption particles, and the plurality of water absorption particles are laid flat between two adjacent extrusion layers 222. The extrusion layer 222 includes a plurality of water absorption thin sheets distributed along the axis direction of the water outlet cylinder 12, and the plurality of water absorption thin sheets extrude the water absorption particles to reduce the possibility of the water absorption particles moving. Both the water absorption particles and the water absorption thin sheets are made of oleophobic and hydrophilic materials, so that while absorbing the moisture in the engine lubricating oil, the possibility of the engine lubricating oil entering the water outlet cylinder 12 is reduced.

[0037] The water-absorbing sheet further compresses the water-absorbing particles after absorbing and swelling. When there is too much water inside the extrusion layer 222 and the water-absorbing layer 221, the water enters the inside of the water outlet cylinder 12 through the water outlet holes 121 on the water outlet cylinder 12 for storage.

[0038] The negative pressure water removal component includes a water suction pipe and a vacuum adsorption pump. One end of the water suction pipe penetrates through the fuel tank and communicates with the water outlet cylinder 12, and the other end of the water suction pipe communicates with the vacuum adsorption pump. The vacuum adsorption pump pumps out the water in the combined filter element 2 through the water suction pipe, so as to extend the service life of the filter component.

[0039] The implementation principle of a combined water-absorbing filter element in an embodiment of the present application is as follows: The filter component is placed inside a fuel tank filled with engine lubricating oil, and the combined filter element 2 is supported and fixed by the filter cylinder 1. The engine lubricating oil contacts the filter component during the flowing process. The cavity wall of the filtering cavity blocks the solid impurities and the engine lubricating oil in the engine lubricating oil. Then, the water-absorbing sheet and the water-absorbing particles absorb and store the water. The absorbed and stored water enters the inside of the water outlet cylinder 12 through the water outlet holes 121 on the water outlet cylinder 12 for further storage. Then, the water inside the combined filter element 2 is regularly pumped out by the vacuum adsorption pump, so as to extend the water in the combined filter element 2 and further reduce the water in the engine lubricating oil.

[0040] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
