Description

Technical Field

[0001] This utility model relates to the field of oil filtration technology, and in particular to a filter element and an oil filtration device for use in an oil filtration apparatus. Background Technology

[0002] In its earlier application 2015203874322, the applicant proposed a filter element structure with several circular holes as liquid outlets and diamond-shaped holes between them as liquid inlets. Compared to the traditional structure where both inlet and outlet holes are circular, this structure obviously has a smaller blank area, higher utilization of the filter element area, and higher filtration performance. However, the lower flange still uses a circular hole structure, with each circular hole corresponding to one of the inlet holes for liquid inlet. Because the shapes of the circular holes and inlet holes are not consistent, if the circular holes are too large, they will impact the edges of the filter element stack during liquid inlet, reducing the lifespan of the filter element; if the circular holes are too small, they will block the inlet holes, thus affecting the liquid inlet volume and reducing filtration efficiency. Secondly, during use, it was also found that during maintenance, the filter element is easily adsorbed by liquid residue, making it difficult to remove from the filter tank; and during assembly, the compression spring is placed separately inside the tank before the filter element is inserted, resulting in low overall assembly efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-tank combination structure for oil filtration that solves or partially solves the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A filter element for an oil filtration device includes a circular upper flange and a lower flange. Several layers of filter element sheets are stacked between the upper and lower flanges. Both the upper and lower flanges have several apertures and flange holes. Several connecting rods passing through the apertures connect the upper and lower flanges. The lower flange is movably mounted on the connecting rods. Several circular liquid outlet holes are arrayed on the filter element sheets. A star-shaped liquid inlet hole is provided between every four liquid outlet holes. Each liquid inlet hole includes four arc-shaped edges parallel to the edges of adjacent liquid outlet holes. The upper flange has a circular liquid outlet corresponding to the liquid outlet holes, the diameter of which is greater than or equal to the diameter of the liquid outlet holes. The lower flange has a liquid inlet corresponding to the liquid inlet holes, with a shape consistent with the liquid inlet holes.

[0019] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0020] In the description of this utility model, it should be noted that the terms "inner", "outer", "upper", "lower", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figures 1 to 5 As shown, a filter element for an oil filtration device according to this utility model includes a circular upper flange 10 and a lower flange 12. Both the upper flange 10 and the lower flange 12 are provided with four through holes 14 (i.e., unthreaded through holes on the inside) and flange holes 40 for connection. Four connecting rods 16 passing through the through holes 14 connect the upper flange 10 and the lower flange 12, ensuring that the lower flange 12 is movably mounted on the connecting rods 16.

[0022] Several layers of filter element stacks 18 are stacked between the upper flange 10 and the lower flange 12. Several circular liquid outlet holes 20 are arrayed on the filter element stacks 18. A star-shaped liquid inlet hole 22 is provided between every four liquid outlet holes 20. Each liquid inlet hole 22 includes four arc-shaped edges parallel to the edges of the adjacent liquid outlet holes 20. The upper flange 10 is provided with a circular liquid outlet 24 corresponding to the liquid outlet holes 20. The diameter of the liquid outlet 24 is greater than or equal to the diameter of the liquid outlet hole 20. The lower flange 12 is provided with a liquid inlet 26 corresponding to the liquid inlet hole 22 with the same shape as the liquid inlet hole 22.

[0023] It also includes a base 28, with a receiving groove 30 at the center of the base 28. A compression spring 32 is installed in the receiving groove 30, and the compression spring 32 abuts against the base 28 and the lower flange 12. Both ends of the connecting rod 16 are provided with threaded portions 34, and the area between the two threaded portions 34 is a smooth rod portion (not marked). The base 28 is also provided with a smooth hole 14 corresponding to the connecting rod 16. The connecting rod 16 passes through the smooth hole 14 of the upper flange 10, the lower flange 12 and the base 28, and is threaded with a nut 36 on the outside, thereby connecting the upper flange 10, the lower flange 12 and the base 28, so that the compression spring 32 abuts against the lower flange 12, thereby compressing the filter element stack 18. During filtration, the compression spring 32 restricts the downward movement of the lower flange 12, allowing the filter element stack 18 to be compressed and tightened, thereby preventing solid impurities from passing through the filter element stack 18, while oil can pass through the filter element stack, that is, from the inlet hole 22 into the outlet hole 20, thus achieving filtration.

[0024] Furthermore, the upper flange 10 is provided with four threaded holes 38 at intervals for separation. The threaded holes 38 and the flange holes 40 on the upper flange 10 are evenly distributed on the same circle. Their function is to prevent the filter element from being easily separated when pulled out of the tank due to adsorption by liquid residue. In this case, a screw threaded into the threaded holes 38 can be used. Rotating the screw causes its front end to press against the tank, thereby squeezing the tank and separating the filter element from it, improving maintenance efficiency.

[0025] Furthermore, an annular sealing groove 42 is provided on the upper end face of the upper flange 10 to accommodate the sealing ring, so that when the filter element is fixed to the tank body by bolts passing through the flange hole 40, the sealing ring is squeezed onto the tank body to form a seal.

[0026] A receiving groove 30 is provided on the filter element stack 18 at the corresponding position of the connecting rod 16.

[0027] The filter cartridge stack 18 is made of a synthetic material specifically designed for solid-liquid separation, which can effectively improve the service life of the filter cartridge stack 18 and can filter water; of course, it can also be made of paper or plastic. The synthetic material can be made of waterproof and oil-resistant materials, and there is a great deal of research on this; appropriate selection is sufficient.

[0028] This utility model also provides an oil filtration device (not shown), which includes a tank and a filter element disposed inside the tank.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
