Description
Technical Field
[0001] This utility model relates to the field of bag filter technology, and in particular to a fixed support structure for a blowpipe and a dust collector. Background Technology
[0002] Baghouse dust collectors are a core means of controlling dust pollution in the metallurgical industry, especially suitable for working conditions with high dust concentrations, high temperatures, and complex compositions. During daily use, a dust layer forms on the surface of the filter bags, enhancing the sieving effect. When the dust accumulated on the filter bag surface causes the dust collector resistance to rise to a set value, the cleaning system is activated. Compressed air is pulsed through a blowpipe to inject high-pressure air into the filter bags, causing them to expand, deform, and vibrate, shaking off the dust adhering to the outer surface of the filter bags into the dust hopper. Current problems include fatigue damage at the pulse-jet nozzles due to traditional bolt fixing methods and support structures, caused by prolonged use under high pressure. This can lead to the blowpipes shifting or falling off in their original installation position, affecting the normal operation of the baghouse dust collector. Utility Model Content

[0022] Baghouse dust collectors are a core means of controlling dust pollution in the metallurgical industry, especially suitable for working conditions with high dust concentrations, high temperatures, and complex compositions. During daily use, a dust layer forms on the surface of the filter bags, enhancing the sieving effect. When the dust accumulated on the filter bag surface causes the dust collector resistance to rise to a set value, the cleaning system is activated. Compressed air is pulsed through a blowpipe to inject high-pressure air into the filter bags, causing them to expand, deform, and vibrate, shaking off the dust adhering to the outer surface of the filter bags into the dust hopper. Current problems include fatigue damage at the pulse-jet nozzles due to traditional bolt fixing methods and support structures, caused by prolonged use under high pressure. This can lead to the blowpipes shifting or falling off in their original installation position, affecting the normal operation of the baghouse dust collector.
[0023] This utility model proposes a fixed support structure for a blowpipe and a dust collector, which aims to improve the service life of the blowpipe and reduce the problem of misalignment or falling off of the blowpipe.
[0024] Please see Figures 1 to 4 In one embodiment of this utility model, the blowpipe fixing support structure 100 includes a mounting plate 1 and a fixing support structure 3. The mounting plate 1 has a mounting surface 11 along its thickness direction, and the mounting surface 11 is used to mount the blowpipe 2. The fixing support structure 3 includes a support part 31 and a fixing part 32. The support part 31 is disposed on the mounting surface 11 and is disposed near the tail of the blowpipe 2, and is used to support the tail of the blowpipe 2. The fixing part 32 is movably disposed on the side of the support part 31 away from the mounting surface 11. The fixing part 32 has a movable stroke relative to the tail of the blowpipe 2 along the thickness direction of the mounting plate 1. Within the movable stroke, the body of the blowpipe 2 is fixed or released.
[0025] The technical solution of this utility model is that the support part 31 bears the main load of the tail of the blow pipe 2, and in conjunction with the movable stroke of the fixing part 32, the blow pipe 2 is allowed to generate a small displacement along the axial direction during high-pressure blowing, thereby dispersing the originally concentrated stress, reducing the stress at the contact position between the blow pipe 2 and the fixed support structure 3, improving the service life of the blow pipe 2 and the fixed support structure 3, and reducing the problem of misalignment or falling of the blow pipe 2.
[0026] In some embodiments, the support part 31 can be fixed to the mounting surface 11 by means of threaded connection, bolt connection or other means, to ensure that the support part 31 can stably bear the tail load of the blow pipe 2.
[0027] Furthermore, the shape and size of the support part 31 can be designed according to the tail structure of the blowpipe 2. For example, when the tail of the blowpipe 2 is cylindrical, the support part 31 can be set as a corresponding arc-shaped groove to fit tightly against the tail of the blowpipe 2, further enhancing the stability and reliability of the support and ensuring the safety performance of the blowpipe 2 during high-pressure blowing.
[0028] In some embodiments, the support portion 31 includes a support plate 311, the interior of which a cavity 3111 is formed, and the fixing portion 32 is disposed within the cavity 3111. This arrangement not only provides sufficient support strength for the support portion 31, but also allows for some space for the movement of the fixing portion 32, enabling the fixing portion 32 to flexibly fix or loosen the blowpipe 2 within its stroke.
[0029] For ease of use, in one embodiment, the support plate 311 is detachably connected to the fixing part 32. This design allows for easy disassembly of the fixing part 32 when maintenance or replacement of the blowpipe 2 is required, enabling quick removal of the blowpipe 2 and improving maintenance convenience. Simultaneously, this detachable connection design makes the blowpipe fixing support structure 100 more flexible, allowing for assembly or adjustment according to different usage requirements.
[0030] In some embodiments, the detachable connection can be a threaded connection, in which the support plate 311 and the fixing part 32 are bolted together with screws for secure installation; or it can be a snap-fit connection, in which the fixing part 32 is snapped into the support plate 311 for secure installation.
[0031] In some embodiments, the fixing part 32 may be movably mounted on the support part 31 via a slide rail, slider or other guide structure to ensure that the fixing part 32 can move smoothly within the active stroke to fix or loosen the blow pipe 2.
[0032] To improve the fixing effect of the fixing part 32 on the blowpipe 2, in one embodiment, the fixing part 32 includes two fixing members 321. The two fixing members 321 are arranged along the thickness direction of the support plate 311, and each of the two fixing members 321 has an arc-shaped opening on its opposite side. Thus, when the fixing part 32 fixes the blowpipe 2, the arc-shaped openings of the two fixing members 321 can fit tightly against the outer peripheral wall of the blowpipe 2, reducing the risk of the blowpipe 2 moving or falling off during high-pressure blowing.
[0033] In this embodiment, the setting method of the fixing member 321 is not specifically limited. For example, the fixing member 321 can be a plate with arc openings on opposite sides of the two plates for clamping the blow pipe 2; or it can be a clamp setting method to fix the tail of the blow pipe 2.
[0034] Furthermore, the shape and size of the fixing part 32 can also be designed according to the tail structure of the blow pipe 2 to ensure a tight fit with the blow pipe 2 and improve the stability and reliability of the fixing.
[0035] Specifically, in one embodiment, the fixing member 321 near the support plate 311 is designated as the first fixing member 3211, and the fixing member 321 away from the support plate 311 is designated as the second fixing member 3212. The side of the first fixing member 3211 away from the second fixing member 3212 extends into the cavity 3111. With this configuration, when it is necessary to fix the blowpipe 2, the blowpipe 2 can be first passed through the gap between the first fixing member 3211 and the second fixing member 3212, with its tail abutting against the second fixing member 3212. Then, the first fixing member 3211 is used to initially clamp and fix the blowpipe 2. Since the first fixing member 3211 extends into the cavity 3111 on the side away from the second fixing member 3212, the first fixing member 3211 can move within the cavity 3111 if the space inside the cavity 3111 allows, thereby absorbing the stress brought about by the operation of the blowpipe 2, reducing the loosening of the blowpipe 2, and improving the service life of the blowpipe fixing support structure 100.
[0036] Meanwhile, by setting the cavity 3111, a buffer structure can be further set inside the cavity 3111 to buffer and reinforce the first fixing member 3211, thereby improving the stability of the fixation.
[0037] To further improve the stability of the jet pipe 2 during high-pressure jetting, in one embodiment, the jet pipe fixing support structure 100 further includes a guide rod 34. The guide rod 34 is located inside the cavity 3111, and both ends of the guide rod 34 extend through the first fixing member 3211 along the width direction of the support plate 311. Thus, when high-pressure gas is jetted through the jet pipe 2, the jet pipe 2 is subjected to a large impact force, which can easily lead to positional displacement or shaking. By providing the guide rod 34 inside the cavity 3111, and with both ends of the guide rod 34 extending through the first fixing member 3211, the jet pipe 2 can be guided and limited, preventing displacement or shaking during high-pressure jetting, thereby improving the stability of the jet pipe 2 during high-pressure jetting. Simultaneously, the guide rod 34 also enhances the overall rigidity and stability of the jet pipe fixing support structure 100, making the entire structure more stable and reliable.
[0038] Furthermore, in one embodiment, an elastic element 35 is sleeved on the outer peripheral wall of the guide rod 34, with both ends of the elastic element 35 abutting against the inner wall of the cavity 3111 and the outer wall of the first fixing member 3211, respectively. Thus, the minute displacement generated by the blowpipe 2 during high-pressure blowing can be absorbed by the mechanical energy of the elastic element 35, providing a certain buffering and damping effect. This further reduces friction and stress concentration between the blowpipe 2 and the fixed support structure 3, protecting the blowpipe 2 and the fixed support structure 3 from damage, improving the service life of the blowpipe 2, and enhancing the stability and reliability of the entire blowpipe fixed support structure 100.
[0039] It is worth noting that this embodiment does not impose specific restrictions on the arrangement of the fixing part 32. It can be made of elastic material, such as a spring, to provide a certain buffering effect when fixing the blow pipe 2, and further reduce the stress concentration problem between the blow pipe 2 and the fixing support structure 3 at the contact position.
[0040] In one embodiment, the blowpipe fixing support structure 100 further includes an adjusting bolt 33, which extends along the width direction of the support plate 311 into the interior of the cavity 3111 and abuts against the fixing part 32. Thus, by rotating the adjusting bolt 33, the position of the fixing part 32 relative to the support plate 311 can be adjusted, thereby achieving fine-tuning of the clamping force and position of the blowpipe 2.
[0041] To improve the adaptability and flexibility of the blowpipe fixing support structure 100, in one embodiment, the two fixing members 321 are configured to be detachably connected. Thus, the fixing members 321 can be selectively installed or removed according to the diameter of the blowpipe 2 to meet the fixing requirements of blowpipes 2 of different specifications.
[0042] This utility model also proposes a dust collector, which includes the fixed support structure 100 for the blowpipe. The specific structure of the fixed support structure 100 for the blowpipe is as described in the above embodiments. Since this dust collector adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0043] In one embodiment, the dust collector further includes a dust collector body 200, a filter bag 201, and a crossbeam 202. The mounting plate 1 is disposed inside the dust collector body 200. The filter bag 201 is disposed on the side of the mounting plate 1 along its thickness direction and away from the blowpipe 2, and the blowpipe 2 is connected to the filter bag 201. The crossbeam 202 is disposed on the inner wall of the dust collector body 200 and near the tail end of the blowpipe 2, and the crossbeam 202 is detachably connected to the support portion 31. The communication between the filter bag 201 and the blowpipe 2 enables effective dust removal. Simultaneously, the crossbeam 202 provides a fixed position for the support portion 31, facilitating the installation and use of the fixed support structure 3. This allows the blowpipe 2 to be supported and fixed during operation, maintaining stability. The detachable connection between the crossbeam 202 and the support portion 31 improves the flexibility of the fixed support structure 3, making maintenance and use easier.
[0044] In some embodiments, the detachable connection between the crossbeam 202 and the support portion 31 can be bolted, screwed, or the like.
[0045] It should be noted that, in order to ensure that the fixed support structure 3 can be installed on the mounting plate 1 and used with the blow pipe 2, a right-angled flat iron is provided on the side of the support plate 311 near the crossbeam 202 for overlapping with the crossbeam 202. At the same time, it can also facilitate the adjustment of the installation position of the support plate 311 and its connection and fixation with the blow pipe 2. An installation pad is provided between the right-angled flat iron and the crossbeam 202 for adjusting the tightness of the installation between the support plate 311, the crossbeam 202, and the blow pipe 2.
[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
