Description

Technical Field

[0001] The utility model relates to the technical field of filter nets, and particularly to a combined filter net. Background Art

[0002] A combined filter net generally refers to a cap-shaped filter structure formed by welding two filter nets or stamping a single filter net.

[0003] Since the combined filter net has an integral structure, when only a part of it is damaged during use, the whole filter net needs to be replaced to ensure the filtering effect, which causes great waste and increases the comprehensive use cost of the equipment equipped with the combined filter net. Content of the Utility Model

[0004] The utility model provides a combined filter net, which solves the problem in the related art that when a part of the combined filter net is damaged, the whole combined filter net needs to be replaced.

[0005] The technical solution of the utility model is as follows:

[0006] A combined filter net includes a filter net body and filter sheets. The filter net body includes a plurality of first filter openings, and the first filter openings are arranged in sequence along a linear direction. The filter sheets include a plurality of second filter openings. The filter net body includes a clamped end and a clamping end. The clamping end and the clamped end are clamped with each other to make the filter net body in a ring structure. The filter sheets are located in the filter net body and are clamped with the filter net body.

[0007] Further, the clamped end includes a plurality of clamping filter openings, and the clamping end includes a plurality of clamping hooks. Each clamping hook is integrally formed with the filter net body, and each clamping hook is clamped with each clamping filter opening in a one-to-one correspondence.

[0008] Further, the clamping filter openings are arranged in sequence along a linear direction in an array, and the number of the clamping filter openings in the axial direction of the filter net body is the same as the number of the first filter openings in the array.

[0009] Further, the filter net body is made of duplex stainless steel.

[0010] Further, the filter sheets include a plurality of clamping columns for clamping the first filter openings and the clamping filter openings. Each clamping column is evenly distributed in a circle around the filter sheet and is integrally formed with the filter sheet.

[0011] Further, one end of each clamping column away from the filter sheet and the end of each clamping hook are both in an arc structure.

[0012] Further, a plurality of filter sheets are provided, and the filter sheets are arranged in sequence along a linear direction.

[0013] Further, the projections of the second filter openings on the adjacent filter sheets are staggeredly distributed on the horizontal plane projection surface.

[0014] Further, the diameter of the filter sheet is greater than the outer ring diameter of the filter net body.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] The present utility model mainly includes a filter net body and a filter sheet. The two ends of the filter net body are respectively provided with a clamping end and a clamped end. Through the clamping (detachable connection) between the clamped end and the clamping end, the filter net body forms an annular structure so as to play a filtering role; the clamping work of the clamping end and the clamped end should be carried out along the axial plane of the filter sheet, that is, after the clamping work of the clamping end and the clamped end is completed, the filter sheet is located inside the filter net body (at the inner ring of the filter net body), and the filter sheet itself can be clamped with the filter net body.

[0017] In this way, with the help of multiple clamping points, the filter net body and the filter sheet form a complete combined filter net. When the filter net body or the filter sheet is damaged due to the filtering work, it can be disassembled in reverse according to the assembly combination sequence of the present utility model, and the damaged part can be replaced and then reassembled to re-guarantee the filtering effect of the present utility model, effectively reducing the comprehensive use cost of the equipment applying the present utility model.

[0026] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1

[0028] As Figure 1 shown, this embodiment proposes a combined filter mesh, mainly including a filter mesh body 1 and a filter sheet 2. The filter mesh body 1 includes a plurality of first filter ports 11, and each first filter port 11 is arranged in sequence along a linear direction. The filter sheet 2 includes a plurality of second filter ports 21 to ensure that the filter mesh body 1 and the filter sheet 2 can perform normal filtering work.

[0029] At the same time, the filter mesh body 1 further includes a clamped end 12 and a clamping end 13. The clamping end 13 and the clamped end 12 are mutually clamped to make the filter mesh body 1 in a ring structure. The filter sheet 2 is located in the filter mesh body 1. That is, by clamping (detachable connection) the clamping end 13 and the clamped end 12, the filter mesh body 1 itself is connected end to end to present a ring structure, and the bending of the filter mesh body 1 (to make the clamping end 13 and the clamped end 12 mutually clamped) is carried out along the circumferential contour of the filter sheet 2. After the clamping end 13 and the clamped end 12 are mutually clamped, the filter sheet 2 can be located in the inner ring of the filter mesh body 1 to complete the assembly work of this embodiment. And to ensure the stability of the overall structure of this embodiment, the filter sheet 2 and the filter mesh body 1 are mutually clamped.

[0030] Specifically, as Figures 2 to 4 shown, the clamped end 12 in this embodiment includes a plurality of clamping filter ports 121, and the clamping end 13 includes a plurality of clamping hooks 131. Each clamping hook 131 is correspondingly clamped to each clamping filter port 121. That is, during the process of bending the filter mesh body 1, by making each clamping hook 131 hook into the grid inside the filter mesh body 1, the clamping work between the clamping end 13 and the clamped end 13 can be completed. On the contrary, this embodiment can be disassembled so that when the filter mesh body 1 or the filter sheet 2 is damaged during subsequent use, only a part of them can be replaced, rather than replacing the whole embodiment, reducing the later maintenance and use costs of the equipment applying this embodiment.

[0031] To facilitate the clamping work between the filter sheet 2 and the filter mesh body 1, the filter sheet 2 further includes a plurality of clamping columns 22 for clamping the first filter ports 11 and the clamping filter ports 121. The clamping columns 22 are evenly distributed in a circular pattern around the filter sheet 2. That is, during the process of bending the filter mesh body 1, the clamping columns 22 can be sequentially inserted into the first filter ports 11 and the clamping filter ports 121 at the same horizontal height as the filter sheet 2 to complete the clamping work between the filter sheet 2 and the filter mesh body 1. And during the clamping process, a plurality of third filter ports can be formed between the filter sheet 2 and the filter mesh body 1 by means of the respective clamping columns 22, thereby improving the filtering efficiency of this embodiment.

[0032] Meanwhile, each clamping hook 131 in this embodiment is integrally formed with the filter mesh body 1 to ensure the connection strength between each clamping hook 131 and the filter mesh body 1, thereby ensuring the final connection (clamping) strength of each clamping hook 131. Each clamping column 22 is integrally formed with the filter sheet 2 to ensure the connection strength between each clamping column 22 and the filter sheet 2, thereby ensuring the clamping strength between the filter sheet 2 and the filter mesh body 1.

[0033] As Figures 1 to 2 shown, the clamping filter ports 121 in this embodiment are sequentially arrayed in a linear direction, and the number of arrays of the clamping filter ports 121 in the axial direction of the filter mesh body 1 is the same as the number of arrays of the first filter ports 11. After the head and tail ends of the filter mesh body 1 are clamped to each other, a plurality of fourth filter ports can be formed between the head and tail ends of the filter mesh body 1 by means of the clamping hooks 131 that are respectively clamped to the clamping filter ports 121 one by one, thereby avoiding the existence of a filtering dead angle between the clamped end 12 and the clamping end 13 and ensuring the filtering effect of this embodiment.

[0034] Meanwhile, an arc-shaped structure is provided at one end of each clamping column 22 away from the filter sheet 2 and at the end of each clamping hook 131, that is, a fillet is made at one end of each clamping column 22 away from the filter sheet 2 and at the end of each clamping hook 131 to avoid the existence of sharp corners at the clamping parts of this embodiment, thereby preventing the staff from being scratched by this embodiment during the assembly process of this embodiment and improving the assembly safety of this embodiment.

[0035] And the longitudinal section of each clamping column 22 should be a rectangular structure, so as to ensure that there is enough contact area between each clamping column 22 and the filter mesh body 1 (the wires of the filter mesh body 1), and further ensure the clamping effect between the filter sheet 2 and the filter mesh body 1.

[0036] The filter mesh body 1 is made of elastic materials such as duplex stainless steel. Thus, when the clamping between the clamping end 13 and the clamped end 12 is completed and no external force is applied to the filter mesh body 1, the elastic force of the filter mesh body 1 itself can be utilized to cause the clamping hooks 131 to start rebounding (moving in the opposite direction of bending), ensuring that each clamping hook 131 can abut against the pore walls of each clamping filter opening 121 (the mesh wires of the filter mesh body 1), fully guaranteeing the clamping effect between the clamping end 13 and the clamped end 12; and since the filter mesh body 1 itself has a certain elasticity, it also facilitates the staff to bend it, thereby improving the assembly efficiency of this embodiment.

[0037] Embodiment 2

[0038] As Figure 1 shown, on the basis of Embodiment 1, the diameter of the filter sheet 2 in this embodiment is larger than the outer ring diameter of the filter mesh body 1, thereby increasing the difficulty for each clamping post 22 to come out between the first filter opening 11 or the clamping filter opening 121 (each grid on the filter mesh body 1) when bending the filter mesh body 1, facilitating the staff to assemble this embodiment and improving the assembly efficiency of this embodiment.

[0039] Embodiment 3

[0040] As Figure 5 shown, on the basis of Embodiment 1 or Embodiment 2, several filter sheets 2 are provided in this embodiment, and the filter sheets 2 are arranged in sequence along the linear direction, that is, by adding the filter sheets 2, the number of filtration times in the axial direction of the filter mesh body 1 in this embodiment is increased, thereby improving the filtration effect of this embodiment.

[0041] Meanwhile, the projections of the second filter openings 21 on adjacent filter sheets 2 are staggeredly distributed on the horizontal plane projection surface, that is, by changing the filtration positions of the respective filter sheets 2, the object to be filtered needs to continuously change its direction, thereby further improving the filtration effect of this embodiment.

[0042] Embodiment 4

[0043] On the basis of Embodiment 1 or Embodiment 2 or Embodiment 3, the filter sheet 2 in this embodiment is also made of elastic materials such as duplex stainless steel, so that during the disassembly process of this embodiment, the filter sheet 2 can be quickly disengaged from the filter mesh body 1 by bending the filter sheet 2, improving the disassembly efficiency of this embodiment.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
