Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration technology, and in particular to a filter element for filtering high-viscosity industrial oil. Background Technology
[0002] Currently, equipment using precision instruments is becoming increasingly sophisticated, which necessitates that the lubricating oil used in precision instruments possess the following properties: extending maintenance cycles as much as possible, shortening downtime, saving costs, saving energy and reducing emissions, improving labor productivity, removing impurities and moisture from the oil, and adsorbing all impurities and moisture onto the filter element. Existing grease filtration typically uses a single layer of filter paper for filtration. Filter paper often breaks after prolonged use, and when filtering highly concentrated industrial oils, the increased density due to the multiple layers of filter paper makes oil film filtration more difficult. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a filter element for filtering high-viscosity industrial oil, thus solving the problem of the difficulty in filtering high-concentration oil films.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a filter element for filtering high-viscosity industrial oil, wherein the filter element is sleeved on the air inlet pipe and includes multiple layers of hollow filter paper rolled into a column shape;
[0005] Multiple support meshes are respectively installed on the inside of each layer of filter paper to prevent the filter paper from being washed away by grease; and
[0006] The upper and lower cover plates are symmetrically arranged at the top and bottom of the outermost layer of filter paper to secure the filter paper to the support mesh.
[0007] Preferably, the support mesh and filter paper are arranged alternately, and the diameter of the multiple layers of support mesh and filter paper gradually increases from the inside to the outside.
[0008] Preferably, the upper side of the upper cover plate is provided with a screw that is threadedly connected to the air intake pipe to fix the filter element.
[0009] Preferably, a gasket is provided between the screw and the upper cover plate, and the gasket is fixedly connected to the screw.
[0010] Preferably, the outer sides of the upper cover plate and the lower cover plate are provided with edging, and the edging on the upper cover plate and the lower cover plate can prevent the rolled-up filter paper from unraveling.
[0011] Preferably, the support mesh is provided with a plurality of support mesh holes evenly distributed.
[0012] Preferably, the support mesh is configured to correspond to the air inlet holes on the air inlet pipe.
[0013] The beneficial effects of this utility model are as follows:
[0014] (1) This utility model uses multiple support nets respectively set on the inner side of each layer of filter paper to prevent the filter paper from being dispersed by high-concentration industrial oil; the thickness of each layer of filter paper can be increased or decreased according to the amount of industrial oil to achieve the best filtration effect. At the same time, the multi-layer support net and filter paper can significantly reduce the thickness of each layer of filter paper compared with the single thick layer of filter paper in the prior art. At this time, while keeping the total thickness of the filter paper unchanged, the gap between each layer of filter paper is changed to reduce the density of each layer of filter paper (because the thickness of multiple layers of filter paper is too thick, and the high concentration of industrial oil cannot easily pass through, resulting in low filtration efficiency). This allows high-concentration industrial oil to easily pass through each layer of filter paper. Then, the multi-layer support net and filter paper can gradually and efficiently filter high-concentration industrial oil. The upper and lower cover plates symmetrically set at the upper and lower ends of the outermost layer of filter paper are used to fasten the filter paper to the support net. The upper and lower cover plates can ensure the vertical alignment of the support net and filter paper and prevent the filter paper and filter net from moving up and down.
[0015] (2) This utility model has a edging on the outer side of the upper cover plate and the lower cover plate. The edging can effectively prevent the rolled filter paper from unraveling, increase the filtration effect of oil and improve the service life.
[0016] (3) By setting multiple filter mesh holes, this utility model can allow high-concentration industrial oil that passes through the filter paper and support mesh to enter the air inlet pipe. While ensuring the support of the filter paper, it can also increase the flow of oil. At the same time, the filter paper is easily broken after being soaked in oil for a long time. The support mesh set inside the filter paper can effectively support the soaked filter paper, increase the service life of the filter paper, and improve work efficiency.
[0017] In summary, this invention has advantages such as improving the filtration efficiency of high-concentration oils. Attached Figure Description

[0024] Example 1
[0025] Figures 1-3 The illustration schematically shows a filter element for filtering high-viscosity industrial oil according to one embodiment of the present invention.
[0026] like Figure 1 As shown, this embodiment provides a filter element for filtering high-viscosity industrial oil. The filter element 1 is sleeved on the air inlet pipe 2 and includes a multi-layer hollow filter paper 3 rolled into a column shape.
[0027] Multiple support meshes 4 are respectively set inside each layer of filter paper 3 to prevent the filter paper 3 from being dispersed by high-concentration industrial oil; the thickness of each layer of filter paper 3 can be increased or decreased according to the amount of industrial oil to achieve the best filtration effect. At the same time, the setting of multiple support meshes 4 and filter paper 3 can significantly reduce the thickness of each layer of filter paper 3 compared with the existing technology of setting a single thick layer of filter paper 3. At this time, while keeping the total thickness of filter paper 3 unchanged, the gap between each layer of filter paper 3 is changed to achieve the effect of reducing the density of each layer of filter paper 3 (because multiple layers of filter paper are stacked together). Industrial oil with excessive thickness and high concentration cannot pass through easily (resulting in low filtration efficiency). This allows high-concentration industrial oil to easily pass through each layer of filter paper 3. Subsequently, the high-concentration industrial oil can be filtered step by step and efficiently through the arrangement of multiple layers of support net 4 and filter paper 3. The upper cover plate 51 and lower cover plate 52, which are symmetrically arranged at the upper and lower ends of the outermost layer of filter paper 3, are used to fasten the filter paper 3 to the support net 4. The upper cover plate 51 and lower cover plate 52 can ensure the vertical alignment of the support net 4 and filter paper 3, and prevent the filter paper 3 and filter net 4 from moving up and down.
[0028] Combination Figure 1-2 As shown, the support mesh 4 and filter paper 3 are alternately arranged, and the diameter of the multi-layer support mesh 4 and filter paper 3 gradually increases from the inside to the outside.
[0029] In this embodiment, the filter paper 3 and the support mesh 4 are coaxially arranged, which can ensure that the filtration intensity is the same in each direction when industrial oil is filtered through the filter paper 3 and the support mesh 4.
[0030] Combination Figure 1 As shown, the upper side of the upper cover plate 51 is provided with a screw 6 that is threadedly connected to the air intake pipe 2 and then used to fix the filter element 1.
[0031] In this embodiment, after the filter element 1 is installed on the air intake pipe 2, it is tightened by the screw 6 engaging with the upper thread of the air intake pipe 2. Of course, the screw 6 only needs to secure the filter element 1 to the air intake pipe 2.
[0032] Combination Figure 1 As shown, a gasket 7 is provided between the screw 6 and the upper cover plate 51, and the gasket 7 is fixedly connected to the screw 6.
[0033] In this embodiment, the gasket 7 can increase the contact area between the screw 6 and the cover plate 5, thereby increasing the stability of the filter element 1 when it is fixed on the air intake pipe 2.
[0034] Combination Figure 3 As shown, the outer sides of the upper cover plate 51 and the lower cover plate 52 are provided with edging 53, which can prevent the rolled-up filter paper 3 from unraveling.
[0035] In this embodiment, the edge binding 53 can effectively prevent the rolled-up filter paper 3 from unraveling, increase the filtration effect on grease, and improve service life.
[0036] Combination Figure 1 As shown, multiple support mesh holes 41 are evenly arranged on the support mesh 4.
[0037] In this embodiment, the arrangement of multiple filter mesh holes 41 allows high-concentration industrial oil passing through the filter paper 3 and the support mesh 4 to enter the air inlet pipe 2. While ensuring the support of the filter paper, it can also increase the flowability of the oil. At the same time, the filter paper 3 is prone to breakage due to the loose surface after being soaked in oil for a long time. The support mesh 4 set inside the filter paper 3 can effectively support the soaked filter paper 3, increase the service life of the filter paper 3, and improve work efficiency.
[0038] Combination Figure 1 As shown, the support mesh 41 is set to correspond to the air inlet on the air inlet pipe 2.
[0039] In this embodiment, the filter mesh 41 and the air inlet 21 are configured to avoid clogging the air inlet 21, which would affect the filtration efficiency and result in low filtration efficiency.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
