Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter cartridge technology, and in particular to a vertical filter cartridge pressing mechanism. Background Technology
[0002] In the laser welding dust removal industry, situations often arise where dust contains sporadic sparks. Most commercially available filter cartridges are horizontally mounted, which easily accumulates dust at the top, posing a safety hazard over time. Considering safety, cost, and ease of maintenance, vertically mounted filter cartridge equipment has been developed. The front-to-back compression sealing method of horizontally mounted cartridges is unsuitable for vertical cartridges. Currently, most rely on bolt tightening, requiring operators to enter the equipment to replace cartridges. This is cumbersome, increases the risk of dust inhalation and secondary pollution, and can lead to problems such as insufficient bolt tightening resulting in poor sealing, or over-tightening causing excessive compression and eventual failure of the sealing strip. Furthermore, nuts, washers, and other accessories are easily lost inside the equipment during cartridge replacement, creating further safety hazards. Spring-locking systems are more complex, have more parts, and are more expensive to manufacture. Utility Model Content

[0027] like Figures 1 to 6As shown, a vertically mounted filter cartridge clamping mechanism includes a fixing component 14, a clamping component 13, and a self-locking component 15. The fixing component 14 is fixed to the dust removal equipment to which it is applied. The clamping component 13 includes a first clamping member 130 and a second clamping member 131 arranged opposite to each other. The first clamping member 130 and the second clamping member 131 are respectively hinged to the fixing component 14. The first clamping member 130 and the second clamping member 131 can clamp and loosen the filter cartridge 4 by rotation. The self-locking component 15 is provided on the clamping component 13 and is used to lock the first clamping member 130 and the second clamping member 131.
[0028] like Figure 5 and Figure 6 As shown, when using the vertical filter cartridge clamping mechanism of this utility model, the fixing component 14 is first installed at the top of the filter cartridge compartment 2 of the dust removal equipment. When the filter cartridge 4 is not installed, the first clamping member 130 and the second clamping member 131 are in the unlocked state. After all the filter cartridges 4 are placed in the filter cartridge compartment 2 and are located on the clamping component 13, the first clamping member 130 and the second clamping member 131 are rotated around the fixing component 14 respectively, so that the first clamping member 130 and the second clamping member 131 clamp the filter cartridges 4 from both sides. Then, the self-locking component 15 is operated to interlock the first clamping member 130 and the second clamping member 131, so that the clamping component 13 reliably clamps the top of the vertical filter cartridge 4.
[0029] When the filter cartridge 4 needs to be replaced, operate the self-locking assembly 15 to release the first clamping member 130 and the second clamping member 131, so that the first clamping member 130 and the second clamping member 131 rotate around the fixing assembly 14 respectively to loosen the filter cartridge 4. At this time, the filter cartridge 4 can be easily pulled out from the outside of the dust removal equipment, and then a new filter cartridge 4 can be replaced according to the above operation method.
[0030] As can be seen, the vertical filter cartridge pressing mechanism 1 of this utility model mainly utilizes a simple lever-type fixing structure to facilitate the assembly and disassembly of the filter cartridge 4. Furthermore, during the replacement of the filter cartridge 4, the operator does not need to enter the filter cartridge chamber 2, ensuring operational safety. The compression amount of the rubber strip can also be adjusted as needed to ensure the sealing effect, preventing the rubber strip from over-compressing and failing. At the same time, this utility model has the advantages of simple structure and low manufacturing cost.
[0031] like Figure 1 and Figure 2 As shown, the clamping assembly 13 in this utility model also includes a first handle 11 and a second handle 12. The first handle 11 is fixed to one end of the first clamping member 130, and the second handle 12 is fixed to one end of the second clamping member 131. In a preferred embodiment, the first handle 11 and the second handle 12 are located at the same end.
[0032] The first handle 11 and the second handle 12 can be mirror images of each other, and the first handle 11 and the second handle 12 are positioned inside and outside each other. Specifically, the first handle 11 can be, but is not limited to, a Z-shaped rod. One end of the first handle 11 can be fixed to one end of the first clamping member 130 by means of rivets, bolts, or other fasteners, so that it can drive the first clamping member 130 to rotate around the fixing assembly 14. The second handle 12 can be, but is not limited to, a Z-shaped rod. One end of the second handle 12 can be fixed to one end of the second clamping member 131 by means of rivets, bolts, or other fasteners, so that it can drive the second clamping member 131 to rotate around the fixing assembly 14. In this embodiment, the end of the second handle 12 that is not connected to the second clamping member 131 is provided with a handle 120, which allows for convenient operation of the second handle 12, further simplifying the operation.
[0033] like Figures 1 to 4 As shown in the diagram, in this embodiment, both the first pressing member 130 and the second pressing member 131 are pressing plates. The first pressing member 130 and the second pressing member 131 are arranged in parallel, and each of the inner sides of the first pressing member 130 and the second pressing member 131 is provided with a positioning groove 132. This positioning groove 132 is used to position the filter cartridge 4, so that the first pressing member 130 and the second pressing member 131 are in surface contact with the filter cartridge 4 to ensure the pressing effect. In addition, the first pressing member 130 and the second pressing member 131 are provided with multiple positioning grooves 132, so that the pressing mechanism 1 of this utility model can press multiple filter cartridges 4 at the same time, further reducing the cost.
[0034] like Figure 1 , Figure 2 and Figure 3 As shown, in this utility model, the self-locking component 15 is disposed on the first handle 11 and the second handle 12.
[0035] The self-locking assembly 15 includes a first limiting plate 150 and a second limiting plate 151. The first limiting plate 150 is used to limit the first handle 11. The first limiting plate 150 is located on the side of the second handle 12, specifically close to (facing) the side of the first handle 11. The first limiting plate 150 and the side of the second handle 12 form a first limiting groove.
[0036] The second limiting plate 151 is used to limit the second handle 12. The second limiting plate 151 is located on the side of the first handle 11, specifically near (facing) the side of the second handle 12. The second limiting plate 151 and the side of the first handle 11 form a second limiting groove. Of course, the self-locking component 15 is not limited to the structure listed above, as long as it can achieve interlocking between the first handle 11 and the second handle 12.
[0037] Specifically, the first handle 11 is horizontally positioned and is locked within the first limiting groove; the second handle 12 is horizontally positioned and is locked within the second limiting groove. At this point, the first handle 11 and the second handle 12 self-lock, effectively achieving self-locking of the first clamping member 130 and the second clamping member 131, thereby reliably clamping the filter cartridge 4. To unlock, first lift the second handle 12 to disengage it from the second limiting groove, then lift the first handle 11 to unlock.
[0038] In this utility model, the fixing component 14 includes at least one fixing groove 140. In a preferred embodiment, the fixing groove 140 is a U-shaped fixing groove, in which case the first clamping member 130 and the second clamping member 131 are respectively hinged to both sides of the fixing groove 140. See [reference needed]. Figure 4 and Figure 5 At this time, the first clamping member 130 and the second clamping member 131 are respectively hinged to both sides of the fixing groove 140 by the hinge 16 and the rivet 17.
[0039] like Figures 1 to 4 As shown in the figure, the fixing component 14 in this embodiment includes two fixing slots 140, one of which is hinged to the first clamping member 130 via a hinge 16, and the other fixing slot 140 is hinged to the second clamping member 131 via a hinge 16.
[0040] like Figure 5 and Figure 6 As shown, in actual use, the second handle 12 is first lifted from the second limiting plate 151, and then the first handle 11 is lifted out of the first limiting plate 150. Both the first handle 11 and the second handle 12 are then lowered to a vertical position. After the first handle 11 and the second handle 12 are in position, the first clamping member 130 is rotated by the first handle 11, and the second clamping member 131 is rotated by the second handle 12, releasing the filter cartridge 4. The top of the filter cartridge 4 falls onto the first clamping member 130 and the second clamping member 131. Pulling the filter cartridge 4 from the outside of the dust removal equipment causes it to be pulled out along the clamping assembly 13.
[0041] After the old filter cartridge 4 is pulled out, place the bottom of the square end cap of the new filter cartridge 4 onto the first clamping member 130 and the second clamping member 131, push the filter cartridge 4 to slide into the filter cartridge 4 layer until it contacts the back baffle of the filter cartridge 4 and stops. Install other filter cartridges 4 in the same way as above.
[0042] After all filter cartridges 4 are installed, first raise the first handle 11 to a 70° angle position (rotate counterclockwise), then raise the second handle 12 (rotate clockwise) so that the first limiting plate 150 clamps the first handle 11. Finally, raise the second handle 12 above the second limiting plate 151, and finally lock the first handle 11 and the second handle 12 on both sides to a horizontal position, so that the first clamping member 130 and the second clamping member 131 press on the filter cartridge 4 respectively. After self-locking, the clamping and fixing of the vertically installed filter cartridge 4 is completed.
[0043] In summary, the vertical filter cartridge pressing mechanism 1 of this utility model has the advantages of simple structure, low cost, and easy processing and manufacturing; moreover, it uses a simple lever-type pressing structure to quickly press the filter cartridge 4 and the tube sheet, thereby realizing the design concept of sealing the filter cartridge 4; when replacing the filter cartridge 4, the operator does not need to enter the equipment, which is safe and convenient; and the compression amount of the rubber strip can be adjusted as needed to ensure the sealing effect, without the problem of excessive compression and failure of the rubber strip, and the manufacturing cost is low.
[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications or improvements to the same vertical filter cartridge pressing mechanism made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
