Description

Technical Field

[0001] The utility model belongs to the technical field of static pressure boxes, and in particular relates to a limiting structure for realizing convenient assembly of a static pressure box body and a filter. Background Art

[0002] Liquid tank type high efficiency filters are widely used in high cleanliness fields such as medicine, food, and data centers. The static pressure box used to install liquid tank type high efficiency filters is made of cold rolled plate bending, welding, and surface spraying, and is equipped with adjustable air valves, diffusion plates, top ears, high efficiency filter blocks and other accessories. With the increasing market demand for increasing the air supply area of ​​high efficiency filters, 13mm wide liquid tank type high efficiency filters have gradually replaced 18mm wide liquid tank type high efficiency filters and are widely used.

[0003] However, during multiple field installations, it was found that due to the reduction in the width of the liquid tank and the manual visual installation process, the filter and its static pressure box body were easily offset, causing the cutting edge of the static pressure box body to come into direct contact with the frame of the filter jelly glue groove, so that the cutting edge could not be completely covered by the jelly glue, resulting in leakage at the edge of the static pressure box body or damage to the frame of the filter jelly glue groove. In addition, the damaged jelly glue surface could not be used a second time and needed to be replaced, increasing costs.

[0004] For example, a Chinese patent with publication number CN205957410U provides a high-efficiency static pressure box with limiting plates, which discloses that limiting plates for fixing high-efficiency filters are arranged around the inner wall of the static pressure box body, and the limiting plates are fitted with the frame of the jelly glue groove of the filter. However, the jelly glue has a strong adhesive force, and it is not convenient to remove the filter by downward force alone. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model aims to propose a limiting structure for realizing convenient assembly of a static pressure box and a filter. The limiting structure solves the problem that the filter and the static pressure box are easily offset during the installation process, resulting in leakage of the filter frame at the edge of the static pressure box and inconvenient disassembly of the filter.

[0006] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0007] A limiting structure for realizing convenient assembly of a static pressure box and a filter, wherein the filter is pushed upward from the bottom of the static pressure box for assembly, a liquid tank is provided at the lower part of the outer periphery of the filter, and jelly glue is filled in the liquid tank, and a bending edge inserted into the jelly glue is provided between the outer periphery of the filter and the inner wall of the static pressure box, and the bending edge is fixed to the inner wall of the static pressure box;

[0008] The limiting structure includes a limiting block, which is located above the bending edge, and the outer side of the limiting block is installed on the inner wall of the static pressure box body; the inner side of the limiting block is divided into a guide part and a limiting part from bottom to top, and the guiding part is inclined from bottom to top toward the center side of the static pressure box body, and the minimum spacing between the limiting part and the outer side of the filter is less than or equal to 3mm.

[0009] Furthermore, the limiting portion is a vertical surface, which is arranged at equal intervals from the outer side of the filter.

[0010] Furthermore, the limiting portion is a curved surface.

[0011] Furthermore, the upper surface of the limiting block is located below the upper surface of the filter.

[0012] Furthermore, the limiting block is integrally formed.

[0013] Furthermore, at least two limiting blocks are evenly arranged between each side wall and the filter in the static pressure box.

[0014] Furthermore, the bending edge 1 is formed by extending inward from the lower end of the static pressure box body and bending downward.

[0015] Furthermore, the lower end of the static pressure box body extends downward and bends outward and upward to form a second bending edge, and the second bending edge is located below the first bending edge. The second bending edge is used to install a diffuser plate.

[0016] Furthermore, a pressing piece for supporting the filter after installation is installed on the horizontal portion of the bending edge 1, and the vertical portion of the bending edge 1 is inserted into the jelly glue.

[0017] Furthermore, the clamping member includes a stud, a pressing plate and a nut, one end of the stud is installed on the horizontal portion of the bending edge 1, and the other end is threadedly connected to the pressing plate and the nut in sequence.

[0018] Compared with the prior art, the limiting structure for realizing convenient assembly of the static pressure box and the filter described in the utility model has the following advantages:

[0019] (1) The limit structure for realizing convenient assembly of the static pressure box and the filter described in the utility model installs limit blocks on the inner walls around the static pressure box, so that the filter can be blindly installed according to the guidance of the limit blocks during the installation process, and the static pressure box and the filter will not produce excessive offset. The bent edge 1 in the static pressure box is inserted into the middle part of the jelly glue to ensure that the jelly glue completely covers the vertical part of the bent edge 1, and the liquid tank frame will not directly contact the vertical part of the bent edge 1, thereby reducing the probability of leakage of the static pressure box and the filter due to assembly problems, and also reducing the problem of increased replacement cost due to leakage caused by assembly problems after the high-efficiency filter is disassembled and the jelly glue surface is damaged and cannot be reused, thereby reducing unnecessary waste and reducing the difficulty of manual operation.

[0020] (2) The limit block guide portion of the utility model for realizing convenient assembly of the static pressure box and the filter is an arc surface, so that downward and left and right forces can be applied to the filter during disassembly. The filter can be disassembled by moving it left and right, which is convenient and fast, saving time and improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] Example 1

[0035] like Figures 1 to 4 As shown, a limiting structure for realizing convenient assembly of a static pressure box and a filter, the filter 1 is pushed upward from the bottom of the static pressure box 2 for assembly, a liquid tank 11 is provided at the lower part of the periphery of the filter 1, and the liquid tank 11 is filled with jelly glue, and a bending edge 21 inserted into the jelly glue is provided between the periphery of the filter 1 and the inner wall of the static pressure box 2, and the bending edge 21 is fixed on the inner wall of the static pressure box 2;

[0036] The limiting structure includes a limiting block 3, which is located above the bending edge 21, and the outer side of the limiting block 3 is installed on the inner wall of the static pressure box 2; the inner side of the limiting block 3 is divided into a guide part and a limiting part from bottom to top, and the guiding part is inclined from bottom to top toward the center side of the static pressure box 2, and the minimum spacing between the limiting part and the outer side of the filter 1 is less than or equal to 3mm.

[0037] In a preferred embodiment of the present invention, the limiting portion 32 is a vertical surface and is arranged at equal intervals from the outer side of the filter 1 .

[0038] In actual use, when the filter 1 is installed into the static pressure box body 2 from the bottom to the top, the vertical part of the bent edge 21 can be inserted into the center position of the jelly glue through the limitation of the limiting part 32, ensuring that the bent edge 21 will not directly contact the frame of the liquid tank 11. The jelly glue completely covers the vertical part of the bent edge 21, so that the filter 1 and the static pressure box body 2 are sealed and not prone to leakage.

[0039] In a preferred embodiment of the present invention, the upper surface of the limiting block 3 is located below the upper surface of the filter 1 .

[0040] The limiting block 3 is integrally formed.

[0041] In actual use, the upper surface of the limiting block 3 is located below the upper surface of the filter 1 and will not limit the left-right tilting of the upper end of the filter 1 .

[0042] In a preferred embodiment of the present utility model, at least two limiting blocks 3 are evenly arranged between each side wall of the static pressure box 2 and the filter 1 .

[0043] In actual use, by installing multiple limit blocks 3 on the inner walls around the static pressure box 2, when the filter 1 is pushed upward from the bottom of the static pressure box 2 into the static pressure box 2, the vertical part of the bent edge 21 can be inserted into the middle part of the jelly glue.

[0044] The limit block 3 cannot be seen during the process of installing the filter 1 into the static pressure box 2 from bottom to top, which is a blind installation; after the filter 1 is installed, the limit block 3 will not be exposed on the outside of the filter 1, and the limit block 3 cannot be seen in the static pressure box 2, which does not affect the installation of the clamping piece 4 and the tightening of the nut 43, nor does it affect the appearance.

[0045] In a preferred embodiment of the present invention, the bending edge 21 is formed by extending the lower end of the static pressure box 2 inwardly and bending downward.

[0046] The lower end of the static pressure box body 2 extends downward and bends outward and upward to form a second bending edge 22 . The second bending edge 22 is located below the first bending edge 21 . The second bending edge 22 is used to install the diffuser plate 5 .

[0047] The horizontal portion of the bending edge 21 is provided with a pressing member 4 for supporting the filter 1 after installation, and the vertical portion of the bending edge 21 is inserted into the jelly glue.

[0048] In actual use, the upper end of the static pressure box body 2 is an air inlet, and the lower end is an air outlet. A diffuser plate 5 is installed at the air outlet, and the diffuser plate 5 is detachably connected to the second bent edge 22.

[0049] The vertical portion of the bent edge 21 and the inner wall of the static pressure box 2 form a space for installing the pressing member 4, which is convenient for installing the pressing member 4 and does not affect the rotation of the pressing plate 42.

[0050] The clamping member 4 includes a stud 41, a pressing plate 42 and a nut 43. One end of the stud 41 is installed on the horizontal portion of the bending edge 21, and the other end is threadedly connected to the pressing plate 42 and the nut 43 in sequence.

[0051] During actual use, when the filter 1 is pushed upward from the bottom of the static pressure box 2 into the static pressure box 2, the top of the frame of the liquid tank 11 abuts against the horizontal part of the bending edge 21, and the vertical part of the bending edge 21 is inserted into the jelly glue, and the jelly glue completely covers the vertical part of the bending edge 21; a plurality of clamping parts 4 are installed on the horizontal part of the bending edge 21, and the rotating pressure plate 42 supports the assembled filter 1, and then the nut 43 is tightened to prevent the rotating pressure plate 42 from loosening.

[0052] The pressure plate 42 and the stud 41 are preferably threadedly connected and then locked by a nut 43 to prevent the pressure plate 42 from loosening; the pressure plate 42 and the stud 41 can also be sleeved, and after the rotating pressure plate 43 abuts against the filter 1, the nut 43 is locked to prevent the filter 1 from falling.

[0053] Working principle of embodiment 1:

[0054] The limiting portion 32 is a vertical surface. The filter 1 is assembled upward from the bottom of the static pressure box body 2 and pushed into the inside of the static pressure box body 2. The filter 1 is limited by the limiting portion 32 so that the vertical portion of the bent edge 21 can be inserted into the middle portion of the jelly glue, and the jelly glue completely covers the vertical portion of the bent edge 21. After the top of the frame of the liquid tank 11 abuts against the extended horizontal portion, the pressure plate 42 is rotated to abut against the bottom of the liquid tank 11 to support the assembled filter 1, and then the nut 43 is tightened to prevent the pressure plate 42 from loosening and causing the filter 1 to fall.

[0055] When the filter 1 is disassembled, the staff applies downward and left and right forces on the bottom of the filter 1, and the filter 1 can be slightly moved left and right according to the distance between the outer side of the filter 1 and the limiting part 32, so as to facilitate disassembly.

[0056] Example 2

[0057] like Figure 5-6 As shown, different from the first embodiment, the limiting portion 32 is a curved surface.

[0058] In actual use, the upper end of the guide portion 31 transitions to the upper surface of the limit block 3 in an arc to form a limit portion 32, and the minimum spacing between the arc surface and the outer side of the filter 1 is less than or equal to 3 mm. While limiting the filter 1, since the limit portion 32 is an arc surface and there is a gap between the guide portion 31 and the filter 1, the filter 1 can be tilted left and right at a larger angle. The staff applies a downward and left and right force on the bottom of the filter 1 to facilitate the disassembly of the filter 1; due to the viscosity of the jelly glue, it is inconvenient to disassemble the filter 1 by only applying a downward force.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
