Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a new type of folded filter element. Background Technique

[0002] A filter element is a purification device required for purifying raw ecological resources and reusing resources. The filter element removes a small amount of solid particles in liquids or air, and can protect the normal operation of equipment or the cleanliness of air. When a fluid enters a filter element with a filter screen of a certain specification, its impurities are blocked, and the clean fluid flows out through the filter element. The filter element has characteristics such as low pressure difference, strong dirt-holding capacity, and long service life, and is applicable to fields such as vacuum coating, machinery, optical discs, metallurgy, petroleum, and refrigeration equipment.

[0003] For example, patent CN218686942U discloses a new type of wire-wound filter element, including a skeleton. The skeleton includes a support column, a positioning disk installed at one end of the support column, and a locking disk detachably installed at the other end of the support column. Sealing members are arranged on both the positioning disk and the locking disk. Yarn is wound around the skeleton, and positioning members for fixing the yarn are arranged on both the positioning disk and the locking disk. However, the filter element filtering component of this filter element is made by a winding method. The filter element made by this manufacturing method has low filtering efficiency, small filtering area and dust-holding capacity, general air permeability, and generally short service life of the filter element. Therefore, a new type of folded filter element is proposed to solve the above-mentioned problems. Content of the Utility Model

[0005] To achieve the above object, the utility model provides the following technical solution: A new type of folded filter element, including a filtering component, and a support component is arranged on the outside of the filtering component;

[0006] The filtering component includes a filtering material, an outer thin cloth, an inner thin cloth, an outer lining net and an inner lining net. An outer thin cloth is arranged on the top of the filtering material, an inner thin cloth is arranged on the bottom of the filtering material, an outer lining net is arranged on the outer thin cloth, and an inner lining net is arranged on the inner thin cloth.

[0007] Further, the support component includes a base located at the bottom of the filtering component. A first connection shell is fixedly connected inside the base. A support cylinder is threadedly connected to the outside of the first connection shell. A second connection shell is threadedly connected inside the support cylinder. A connection seat is fixedly connected to the outside of the second connection shell.

[0008] Further, the filter material is polypropylene.

[0009] Further, the filter assembly is folded into neat and compact strips by a folder.

[0010] Further, the top of the second connection shell penetrates and extends to the top of the connection seat.

[0011] Further, a plurality of hydrophobic holes are formed in the support cylinder.

[0012] Further, the plurality of hydrophobic holes are equidistantly distributed on the support cylinder.

[0013] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0014] 1. For this new type of foldable filter element, by setting the filter assembly, the filter materials, outer thin cloth, inner thin cloth, outer lining net and inner lining net required for the filter element are laid and overlapped layer by layer, and then folded into neat and compact strips by a folder. The filter element made in this way has about three times more filter area than the original traditional wound filter element, further increasing the dust holding capacity of the filter element. The sufficient space between the filter materials well ensures the air permeability of the filter element, reduces the pressure difference during the use of the filter element, and greatly improves the service life of the filter element. The outer thin cloth and inner thin cloth wrapped around the material can prevent the internal filter material from leaking out after being impacted by air pressure while ensuring the overall air permeability of the filter element. The outer lining net and inner lining net wrapped around the inside and outside of the filter element also improve the strength of the filter element to a certain extent, thereby improving the pressure bearing capacity of the filter element.

[0015] 2. For this new type of foldable filter element, by setting the support assembly, the foldable filter element has the function of support, achieving the effect of supporting the filter assembly, thereby increasing the structural strength of the filter assembly, delaying deformation, and further extending the service life of the filter assembly, facilitating the use of the user and increasing the practicability of the foldable filter element.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Embodiment 1. Please refer to Figures 1 to 4 , A new type of foldable filter element in this embodiment includes a filter component 1. The filter component 1 is folded into neat and compact strips by a folding machine, and a support component 2 is arranged outside the filter component 1.

[0023] The filter component 1 includes a filter material 11, an outer thin cloth 12, an inner thin cloth 13, an outer lining mesh 14 and an inner lining mesh 15. An outer thin cloth 12 is arranged on the top of the filter material 11, an inner thin cloth 13 is arranged on the bottom of the filter material 11, an outer lining mesh 14 is arranged on the outer thin cloth 12, and an inner lining mesh 15 is arranged on the inner thin cloth 13. The filter material 11 is made of materials with good chemical stability such as polypropylene.

[0024] It should be noted that the filter element made in this way has increased the filtration area by about three times compared with the original traditional winding filter element, further increasing the dust holding capacity of the filter element. The sufficient space between the filter materials well ensures the air permeability of the filter element, reduces the pressure difference during the use of the filter element, and greatly improves the service life of the filter element. The outer thin cloth 12 and the inner thin cloth 13 wrapped around the material can prevent the internal filter material from leaking out after being impacted by air pressure while ensuring the overall air permeability of the filter element. The outer lining mesh 14 and the inner lining mesh 15 wrapped inside and outside the filter element also improve the strength of the filter element to a certain extent, thereby improving the pressure bearing capacity of the filter element.

[0025] Embodiment 2. In this embodiment, the support component 2 includes a base 21 located at the bottom of the filter component 1. A first connection shell 22 is fixedly connected inside the base 21. A support cylinder 23 is threadedly connected to the outside of the first connection shell 22. A plurality of hydrophobic holes 26 are formed in the support cylinder 23. The plurality of hydrophobic holes 26 are equidistantly distributed on the support cylinder 23. A second connection shell 24 is threadedly connected inside the support cylinder 23. A connection seat 25 is fixedly connected to the outside of the second connection shell 24. The top of the second connection shell 24 penetrates and extends to the top of the connection seat 25.

[0026] In this embodiment, by providing a support assembly, the effect of supporting the filter assembly 1 is achieved, thereby increasing the structural strength of the filter assembly 1, delaying deformation, and further extending the service life of the filter assembly 1.

[0027] The working principle of the above embodiment is as follows: for this new type of foldable filter element,

[0028] 1) When in use, by providing the filter assembly 1, the filter materials 11, outer thin cloth 12, inner thin cloth 13, outer lining mesh 14, and inner lining mesh 15 required for the filter element are laid flat and overlapped layer by layer, and then folded into neat and compact strips by a folding machine. The filter element made in this way has approximately three times the filtering area compared to the original traditional wound filter element, further increasing the dust holding capacity of the filter element. The sufficient space between the filter materials well ensures the air permeability of the filter element, reduces the pressure difference during the use of the filter element, and greatly improves the service life of the filter element. The outer thin cloth 12 and inner thin cloth 13 wrapped around the material prevent the internal filter materials from leaking out after being impacted by air pressure while ensuring the overall air permeability of the filter element. The outer lining mesh 14 and inner lining mesh 15 wrapped around the inside and outside of the filter element also improve the strength of the filter element to a certain extent, and thus improve the pressure bearing capacity of the filter element.

[0029] 2) By providing the support assembly 2, the support cylinder 23 is screwed onto the outside of the first connection shell 22, and then the support cylinder 23 is inserted into the folded filter assembly 1. The bottom of the filter assembly 1 is inserted into the inside of the base 21, and then the second connection shell 24 fixedly connected to the connection seat 25 is screwed into the top of the support cylinder 23, thereby limiting and fixing the top of the filter assembly 1. By providing the hydrophobic holes 26, the pressure of the water flow entering the filter element is reduced, further improving the strength of the filter element, and thus improving the pressure bearing capacity of the filter element, delaying deformation, and further extending the service life of the filter assembly 1, facilitating the use of the user, and increasing the practicality of the foldable filter element.
