Description

Technical Field

[0001] This utility model relates to the technical field of waste gas purification equipment, and in particular to a quick-release structure for filter elements in a filter box. Background Technology

[0002] Industrial waste gas emissions are generated in industries such as painting, petrochemicals, packaging and printing, and furniture manufacturing. These gases are diverse, complex in composition, and varied in properties. Furthermore, different industries exhibit different emission characteristics; the painting industry, in particular, commonly experiences the coexistence of paint mist particles and organic waste gases. Waste gases are typically purified through adsorption materials. Once these materials become saturated, they need to be replaced or regenerated through desorption. Due to the high production cost of adsorption materials, waste gases are pre-treated by filtration devices before being purified.

[0003] A filtration device typically refers to a filter box, which contains multi-stage filtration modules arranged along the length of the filter box. Each filtration module includes a filter frame and filter elements arranged on the filter frame. In the prior art, filter elements are usually fixed to the filter frame with bolts, which is complicated to disassemble and assemble. Utility Model Content

[0004] To improve the efficiency of filter element assembly and disassembly, this application provides a quick-release structure for filter elements in a filter box.

[0005] This application provides a quick-release structure for a filter element in a filter box, which adopts the following technical solution:

[0006] A quick-release structure for filter elements in a filter box is provided for installing filter elements on a filter frame. It includes a mounting base disposed between two adjacent filter elements, the mounting base being mounted on the filter frame. A fastening block is rotatably connected to the side of the mounting base facing the ground. The mounting base is provided with a control elastic element for controlling the rotation of the fastening block toward the filter frame. A support portion is provided on the side of the mounting base opposite to the fastening block, which cooperates with the mounting base to provide support for the filter elements. The support portion is perpendicular to the mounting base.

[0007] By adopting the above technical solution, during the actual installation of the filter element, four mounting seats are located at the four corners of the filter element. After moving the filter element to the area between the two support parts near the ground and the filter frame, the fastening block can be rotated until the positioning block is embedded in the corresponding positioning groove, thus completing the installation of the filter element. During disassembly, it is only necessary to rotate the fastening block to release the positioning block from locking the filter element, which facilitates the installation and removal of the filter element and effectively improves the installation efficiency of the filter element. Without the action of other external forces, the fastening block can be pressed against the filter element under the action of the control elastic element, making it difficult for the filter element to detach from the filter frame and improving the reliability of the filter element fixed on the filter frame.

[0008] Preferably, the filter element is provided with positioning grooves at its corners, and the fastening block is provided with positioning blocks that cooperate with the positioning grooves.

[0009] By adopting the above technical solution, the positioning block and the positioning groove cooperate to fix the filter element on the filter frame, making it less likely for the filter element to shift relative to the filter frame, thus improving the reliability of the filter element installed on the filter frame.

[0010] Preferably, the end face of the filter element facing away from the positioning groove is provided with a sealing strip, the sealing strip is elastic, and the end face of the sealing strip facing away from the filter element abuts against the filter frame.

[0011] By adopting the above technical solution and setting the sealing strip, the gap between the filter element and the fastening block and support is reduced. This not only improves the stability and reliability of the filter element installed on the filter frame, but also makes it difficult for exhaust gas to flow out from the gap between the filter element and the filter frame, thus ensuring the filtration effect of exhaust gas to a certain extent.

[0012] Preferably, a limiting rod is rotatably connected to the support portion, the end of the limiting rod away from the support portion is bent, and a limiting ring is provided on the fastening block to cooperate with the limiting rod. The limiting ring cooperates with the limiting rod to restrict the rotation of the fastening block.

[0013] By adopting the above technical solution, during the maintenance of the filter element, the rotation of the fastening block can be restricted by the cooperation of the limiting rod and the limiting ring. After the maintenance is completed, the restriction of the fastening block rotation by the limiting rod can be released, thereby improving the disassembly and assembly efficiency of the filter element to a certain extent, reducing working time during the dust cleaning process of the filter element, and protecting the health of the staff to a certain extent.

[0014] Preferably, the fastening block, mounting base, and support are all provided with limiting grooves for the limiting rod to engage, and the fastening block is provided with a control groove communicating with the limiting groove, the depth of the control groove decreasing sequentially in the direction away from the limiting groove.

[0015] By adopting the above technical solution, in actual application, the limiting rod can also restrict the fastening block from rotating away from the filter frame, further improving the reliability of the filter element installed on the filter frame; the setting of the control groove makes it easy to remove the limiting rod located in the limiting groove.

[0016] Preferably, the mounting base has a through hole for weight reduction.

[0017] By adopting the above technical solution, the weight-reducing through-hole design reduces the production cost of this quick-release structure.

[0018] Preferably, the mounting base has a C-shaped mounting piece on the side facing the filter frame, the opening of the mounting piece is facing the filter frame, and the mounting piece is in contact with the filter frame.

[0019] By adopting the above technical solution, the mounting plate is set up as a mounting base to provide support and positioning on the filter frame, which effectively improves the reliability of the mounting base being fixed on the filter frame. In actual application, the crossbars of the mounting plate can be fixed with bolts, so that the mounting base and the filter frame are detachably connected, which facilitates the inspection and maintenance of the mounting base.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. During the actual installation of the filter element, four mounting bases are located at the four corners of the filter element. After moving the filter element to the two support parts near the ground and between the filter frame, the fastening block can be rotated until the positioning block is embedded in the corresponding positioning groove to complete the installation of the filter element. When disassembling, it is only necessary to rotate the fastening block to release the positioning block from locking the filter element, which facilitates the installation and disassembly of the filter element and effectively improves the installation efficiency of the filter element.

[0022] 2. By setting the sealing strip, the gap between the filter element and the fastening block and support is reduced, which not only improves the stability and reliability of the filter element installed on the filter frame, but also makes it difficult for exhaust gas to flow out from the gap between the filter element and the filter frame, thus ensuring the filtration effect of exhaust gas to a certain extent.

[0029] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0030] This application discloses a quick-release structure for a filter element in a filter box, referring to... Figure 1 , Figure 2 and Figure 3 This device is used to install filter element 1 on filter frame 2. It includes a mounting base 3 disposed between two adjacent filter elements 1. The filter frame 2 is welded together by multiple vertical rods 21 and horizontal rods 22. The number of vertical rods 21 and horizontal rods 22 depends on the actual size of the filter frame 2. The mounting base 3 is disposed at the intersection of the vertical rods 21 and horizontal rods 22. The mounting base 3 has a C-shaped mounting piece 31 on the side facing the filter frame 2. The opening of the mounting piece 31 faces the filter frame 2. In the actual installation process, the mounting piece 31 is fitted to the filter frame 2. The mounting piece 31 provides support and positioning for the mounting base 3 on the filter frame 2, effectively improving the reliability of the mounting base 3 fixed on the filter frame 2. In actual application, the mounting piece 31 and the horizontal rods 22 can be fixed together by bolts, so that the mounting base 3 and the filter frame 2 are detachably connected, which facilitates the inspection and maintenance of the mounting base 3.

[0031] Reference Figure 3 and Figure 4 The mounting base 3 is rotatably connected to a fastening block 32 on the side facing the ground. The mounting base 3 has a rotating column 321, and the fastening block 32 has a rotating through hole 322 for the rotating column 321 to be inserted. The mounting base 3 has a control elastic element for controlling the rotation of the fastening block 32 toward the filter frame 2. In this embodiment, the control elastic element is a control torsion spring 323, which is sleeved on the rotating column 321. One end of the control torsion spring 323 is fixed to the fastening block 32, and the other end is fixed to the rotating column 321. Without any external force, the fastening block 32 can be pressed against the filter element 1 by the control torsion spring 323, making it difficult for the filter element 1 to detach from the filter frame 2, thus improving the reliability of the filter element 1 fixed to the filter frame 2.

[0032] Reference Figure 3The filter element 1 has positioning grooves 11 at each corner, and the fastening block 32 has positioning blocks 324 that cooperate with the positioning grooves 11. Since most of the filter elements 1 are square, no adjustment is needed during actual installation, and they can be installed at any angle. The positioning blocks 324 cooperate with the positioning grooves 11 to fix the filter element 1 to the filter frame 2, making it less likely for the filter element 1 to shift relative to the filter frame 2, thus improving the reliability of the filter element 1 installed on the filter frame 2. Since the fastening block 32 rotates to allow the positioning blocks 324 to embed into the positioning grooves 11, the positioning grooves 11 include a clearance area for the positioning blocks 324, reducing jamming during the installation of the filter element 1 and effectively improving the installation efficiency of the filter element 1.

[0033] Reference Figure 3 and Figure 5 The mounting base 3 has an integrally formed support part 33 on the side opposite to the fastening block 32, which cooperates with the mounting base 3 to provide support for the filter element 1. The support part 33 is set perpendicular to the mounting base 3. In the actual installation process of the filter element 1, the installation of a single filter element 1 requires the cooperation of four mounting bases 3. After moving the filter element 1 between the two support parts 33 near the ground and the filter frame 2, the fastening block 32 can be rotated until the positioning block 324 is embedded in the corresponding positioning groove 11 to complete the installation of the filter element 1. When disassembling, it is only necessary to rotate the fastening block 32 to release the locking of the positioning block 324 on the filter element 1, which facilitates the disassembly and assembly of the filter element 1 and effectively improves the installation efficiency of the filter element 1.

[0034] Reference Figure 3 and Figure 5 A sealing strip 12 is provided on the end face of the filter element 1 facing away from the positioning groove 11. The sealing strip 12 is elastic and abuts against the filter frame 2. By setting the sealing strip 12, the gap between the filter element 1 and the fastening block 32 and the support part 33 is reduced. This not only improves the stability and reliability of the filter element 1 installed on the filter frame 2, but also makes it difficult for exhaust gas to flow out from the gap between the filter element 1 and the filter frame 2, thus ensuring the filtration effect of exhaust gas to a certain extent. A weight-reducing through hole 34 is provided through the mounting base 3. The setting of the weight-reducing through hole 34 reduces the production cost of this quick-release structure.

[0035] Reference Figure 3 and Figure 4A limiting rod 331 is rotatably connected to the support part 33. The end of the limiting rod 331 away from the support part 33 is bent. The fastening block 32 is provided with a limiting ring 325 that cooperates with the limiting rod 331. The limiting ring 325 cooperates with the limiting rod 331 to restrict the rotation of the fastening block 32. During the maintenance of the filter element 1, the rotation of the fastening block 32 can be restricted by the cooperation of the limiting rod 331 and the limiting ring 325. After the maintenance is completed, the limitation of the limiting rod 331 on the rotation of the fastening block 32 can be released. This can improve the disassembly and assembly efficiency of the filter element 1 to a certain extent, reduce working time during the cleaning of the filter element 1, and protect the health of the staff to a certain extent.

[0036] Reference Figure 4 The fastening block 32, the mounting base 3, and the support part 33 are all provided with limiting grooves 332 for the limiting rod 331 to fit into. In actual application, the limiting rod 331 can also restrict the fastening block 32 from rotating away from the filter frame 2, further improving the reliability of the filter element 1 installed on the filter frame 2. The fastening block 32 is provided with a control groove 333 that communicates with the limiting groove 332. The depth of the control groove 333 decreases sequentially in the direction away from the limiting groove 332. By setting the control groove 333, it is easy to remove the limiting rod 331 located in the limiting groove 332.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
