Technical Field
[0001] This utility model relates to the field of filter bag technology, specifically a dust removal filter bag for use in high-temperature environments. Background Technology
[0002] Filter bags possess excellent chemical stability and heat resistance, representing the highest performance in the filter media industry and the most advanced type of commonly used filter materials. They achieve high levels in filtration efficiency and precision. However, high temperatures during use can affect the filtration capacity of filter bags. Therefore, high-temperature dust removal filter bags are required to adapt to high-temperature dust removal applications.
[0003] Existing dust collector filter bags used in high-temperature environments have certain defects in actual use. When installing the filter bags, some are fixed to the top and bottom of the filter bag with screws. However, during use, the filter bag is prone to displacement or shaking under the action of airflow, which will affect the dust removal effect. Utility Model Content
[0004] The purpose of this invention is to provide a dust removal filter bag for use in high-temperature environments, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust removal filter bag for use in high-temperature environments, comprising a filter bag body, a fixing ring at the top of the filter bag body via an insertion assembly, an mounting block at the fixing ring via a fastening assembly, an auxiliary assembly below the fixing ring, a positioning assembly at the bottom of the auxiliary assembly, and a hook at the bottom of the filter bag body for use with the positioning assembly.
[0006] Preferably, in order to facilitate the insertion and fixing of the top of the filter bag body and facilitate subsequent assembly and tightening, the insertion assembly includes insertion blocks equidistantly arranged on the periphery of the filter bag body, the bottom end of the fixing ring is provided with an insertion groove that matches the insertion block, and the inner wall of the insertion groove is provided with an anti-slip pad.
[0007] Preferably, in order to facilitate the connection and fixation of the retaining ring and the plug block, the fastening assembly includes threaded holes formed on the mounting block, the retaining ring and the plug block, with a positioning screw engaged in the threaded hole by threads, and a washer provided on the positioning screw.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 This utility model provides an embodiment of a dust removal filter bag for high-temperature environments, comprising a filter bag body 1. The filter bag body 1 can be made of polyphenylene sulfide filter bag, polytetrafluoroethylene filter bag, glass fiber filter bag, etc., and can be used in high-temperature environments according to different situations without affecting the dust removal effect. The peripheral side of the open end of the filter bag body 1 is connected to a fixing ring 2 through a plug-in component. The fixing ring 2 is fixedly connected to the mounting block 3 through a fastening component. The mounting block 3 is a partial illustration of the interior of the dust removal device, which facilitates the installation of the filter bag body 1 inside the dust removal device. This is a relatively mature technology and will not be described in detail here. In order to ensure that there is no displacement or collapse during assembly and use, which would affect the dust removal effect, an auxiliary component is provided under the fixing ring 2. The bottom end of the auxiliary component is provided with a positioning component. The bottom end of the filter bag body 1 is equipped with a hook 16 for connection and positioning with the positioning component. In order to facilitate the assembly and lifting of the filter bag body 1, pull rings 6 are symmetrically installed on the top end (open end) of the filter bag body 1.
[0022] Please see Figures 1-4To facilitate installation and positioning, as well as subsequent disassembly, the filter bag body 1 has plug-in blocks 12 of the plug-in assembly installed at equal intervals on the top and circumferential sides. The bottom of the corresponding fixing ring 2 has a plug-in groove 10 for easy insertion of the plug-in blocks 12. To ensure proper insertion, an anti-slip pad 11 (which can be made of high-temperature resistant rubber) is adhered to the inner wall of the plug-in groove 10. For easy fastening and subsequent disassembly, threaded holes 14 are provided on the mounting block 3, fixing ring 2, and plug-in blocks 12. Positioning screws 4 are threaded into the threaded holes 14. To ensure a tight fit, washers 5 are fitted over the positioning screws 4. Two sets of auxiliary component connecting rods 7 are symmetrically welded to the bottom of the fixing ring 2. An auxiliary ring 9 is welded to the bottom, and straps 8 (which can be sewn or glued) are provided at equal intervals around the filter bag body 1. These straps facilitate connection and positioning with the connecting rod 7 to prevent displacement and also facilitate subsequent disassembly. A horizontal bar 15 for positioning components is welded to the bottom of the auxiliary ring 9. An anti-slip sleeve 17 (also made of high-temperature resistant rubber) is fitted in the middle of the horizontal bar 15. Anti-slip protrusions 13 (made of the same material as the anti-slip sleeve 17, which can be integrally molded or glued) are provided at equal intervals around the anti-slip sleeve 17. The hook 16 at the bottom of the filter bag body 1 can be hung on the horizontal bar 15 to ensure that it will not shift during use, thus ensuring the dust removal effect and facilitating subsequent disassembly, cleaning, or replacement.
[0023] Working principle: In use, the fixing ring 2 is first assembled using the positioning screw 4, and then fixedly connected to the mounting block 3 using the threaded hole 14. Next, the filter bag body 1 is inserted between the fixing ring 2 and the auxiliary ring 9, and the bottom is hung on the anti-slip sleeve 17 of the crossbar 15 via the hook 16 for initial positioning and fixation. The filter bag body 1 is then pulled upwards using the pull ring 6, allowing the insertion block 12 to be inserted into the insertion groove 10, where it is initially positioned and fixed using the anti-slip pad 11. Then, the positioning screw 4 is rotated to connect and fix the filter bag body 12 using the threaded hole 14. The strap 8 is connected and tightened to the connecting rod 7 to ensure that it will not shift or collapse during subsequent dust removal use, thus not affecting the dust removal function. When it is necessary to disassemble for cleaning or replacement, turn the positioning screw 4 counterclockwise to turn it out of the threaded hole 14 on the plug block 12. It is still inside the fixing ring 2. At this time, the positioning and fixing of the plug block 12 is lost. At the same time, untie the strap 8, pull down the filter bag body 1, and take out the plug block 12 from the plug groove 10. Then remove the hook 16 to take out the filter bag body 1 from between the fixing ring 2 and the auxiliary ring 9 for easy cleaning or replacement.
[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
