Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of filter paper production, in particular to a multi-folded filter element. Background Art
[0002] During use, the filter element is used as a simple device for filtering and purification. It can separate impurities in liquids, filter gases, and filter oils. It has a wide range of applications. At the same time, the filter element has a variety of materials. Filter elements of different structures and materials are selected according to the scope and field of use. Paper filter elements have a wide range of applications as a lower-cost material. During use, different filtering effects are achieved through the contact surface between the paper filter paper and the required filter medium. In the existing production process, the contact area of the paper filter paper is increased within the same circumference by folding to improve the filtering effect. Without changing the overall diameter of the filter element, increasing the folded surface of the filter paper is an effective way to improve the filtering effect while reducing production costs. Therefore, the following technical method is proposed. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of the utility model is to provide a multi-fold filter element to increase the contact surface of the filter paper in the existing filter element, thereby improving the purification effect.
[0004] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical scheme: a multi-fold filter element, including a filter element as a whole, the filter element as a whole is distributed as multiple folded components, the multiple folded components are formed by folding filter paper, and the filter paper is folded and fixed around the circumference to form a filter element, the folded component includes a first folded surface folded from the outside to the center, the first folded surface is symmetrically arranged, and there are two symmetrical first V-shaped surfaces folded between the outer ends of the first folded surface toward the center of the filter element, and a second V-shaped surface is folded toward the outside of the filter element in the middle of the inner end of the first folded surface. The first V-shaped surface and the second V-shaped surface have the same depth, and the folded components constitute the filter element as a whole. The overall filter element contact surface uses 1.5 times more material than the traditional filter element contact surface, and the filtering effect is enhanced.
[0005] The preferred structure of this solution includes that the depth of the first folding surface is twice the depth of the first V-shaped surface and the second V-shaped surface.
[0006] A preferred structure of this solution also includes that the angles of the first V-shaped surface and the second V-shaped surface are the same.
[0007] As another preferred structure of this solution, the sum of the areas between the first V-shaped surface and the second V-shaped surface is 1.5 times the sum of the areas of the two first folding surfaces, thereby improving the filtering effect.
[0008] As another preferred structure of this solution, the inner ends of the folding components are connected.
[0009] As another preferred structure of this solution, the folding component interface is located at the top end of the second V-shaped surface, the top ends are sealed and connected, and the adjacent folding component ends are connected.
[0010] The beneficial effect of the present invention is that a filter element is formed by arranging a folding component and assembling around it. The folding component is provided with 8 folding surfaces. Compared with the traditional filter element, the amount of paper used in this technical solution is 1.5 times more on the filter element of the same diameter. At the same time, the folding surface is 1.5 times more than that of the traditional filter element, which increases the contact area between the filter element and the required filter material during use and improves the filtering effect. The specific implementation method is further described in the following embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0015] See also Figure 1 and Figure 2 , including a filter element as a whole, the filter element as a whole is distributed into multiple folded components, and the multiple folded components are formed by folding filter paper. After the filter paper is folded, the circumference is fixed around the filter element to form the folded component, the folded component includes a first folded surface folded from the outside to the center, the first folded surface is symmetrically arranged, and two symmetrical first V-shaped surfaces are folded between the outer ends of the first folded surface toward the center direction of the filter element, and a second V-shaped surface is folded in the middle of the inner end of the first folded surface toward the outside direction of the filter element. The first V-shaped surface and the second V-shaped surface have the same depth, and the folded component forms the filter element as a whole. The overall filter element contact surface is 1.5 times more material than the contact surface of the traditional filter element, and the filtering effect is enhanced. The depth of the first folded surface is twice the depth of the first V-shaped surface and the second V-shaped surface, the angles of the first V-shaped surface and the second V-shaped surface are the same, and the sum of the areas between the first V-shaped surface and the second V-shaped surface is 1.5 times the sum of the areas of the two first folded surfaces, thereby improving the filtering effect. The inner ends of the folded components are connected, the folded component interface is located at the top of the second V-shaped surface, the top ends are sealed and connected, and the ends of adjacent folded components are connected.
[0016] During the implementation process, the folding method of the folding component is to fold the filter paper into an M shape, leaving a distance greater than twice the bottom of the two sides of the M shape, and the center depth of the M shape is the same as the length of the two sides. The middle part of the M-shaped origami is pulled out, and then two V-shaped folded surfaces are folded inward. The two sides of the M-shaped origami are folded inward, and the interface is sealed. Repeat the operation, fold multiple folding components, and assemble them around to form a filter element. The overall folding surface uses 1.5 times more material and area than the traditional V-shaped folding surface, thereby improving the filtering effect of the filter element.
