[0018] The following detailed description will further describe the invention with reference to the above mentioned drawings. DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of the invention, the invention will be described more fully below in connection with the attached drawings. The drawings show several embodiments of the invention. However, the invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0020] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can also be present. As used herein the terms "vertical", "horizontal", "left", "right" and similar expressions are used for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0022] As Figures 1 to 4As shown, an industrial bag filter dust collector according to the present invention includes: a housing 10, a pulse assembly 20 disposed on the housing 10, a filter assembly 30 disposed within the housing 10, and a partition plate 40 disposed within the housing 10. The partition plate 40 divides the interior of the housing 10 into a lower filter chamber 11 and an upper clean chamber 12. The pulse assembly 20 includes multiple pulse tubes 21 disposed within the clean chamber 12, a fixing plate 22 connected to one end of the multiple pulse tubes 21, and multiple supply tubes 23 connected to the other end of the multiple pulse tubes 21. One end of all the pulse tubes 21 is connected to the fixing plate 22 by a fixing member 24 (fixing bolt). The other end of each pulse tube 21 is detachably connected to the supply port of a corresponding supply tube 23 by a fixing clamp 25. Both ends of the fixing plate 22 are detachably connected to the side wall of the clean chamber 12 by positioning members 26.

[0023] It is worth noting that all pulse tubes 21 are integrated into a single module via a fixing plate 22 and connected by a detachable positioning element 26 and a fixing clamp 25. When the filter bag needs maintenance, the entire pulse tube 21 module or a portion of the pulse tubes 21 can be quickly unfixed, greatly avoiding the need for "disassembly one by one" and allowing maintenance personnel to quickly and easily access the filter bag below.

[0024] like Figures 5 to 8 As shown, the fixing hoop 25 further includes a lower hoop body 252 and an upper hoop body 251. One end of the lower hoop body 252 and the upper hoop body 251 are hinged to each other. The other end of the lower hoop body 252 is hinged to a locking handle 253. The other end of the upper hoop body 251 is provided with a slot 254 that is adapted to the locking handle 253. When the lower hoop body 252 and the upper hoop body 251 are fastened together, the locking handle 253 can be inserted into the slot 254 to achieve locking.

[0025] Furthermore, the inner walls of the lower hoop 252 and the upper hoop 251 are both provided with semi-circular grooves 255. When the two are fastened together, the grooves 255 together form a complete limiting ring groove 256. The pulse tube 21 has a first connecting flange 27 extending radially from its connecting end, and the supply port of the supply tube 23 has a second connecting flange 28 extending radially from its supply port. A sealing ring 29 is sandwiched between the first connecting flange 27 and the second connecting flange 28. The total thickness of the first connecting flange 27, the sealing ring 29, and the second connecting flange 28 is adapted to the width of the limiting ring groove 256.

[0026] Further, annular first and second embedding grooves 271 and 281 are respectively formed on the opposite faces of the first and second connecting flanges 27 and 28; the two side end faces of the sealing ring 29 are correspondingly formed with annular first and second sealing flanges 291 and 292; the first sealing flange 291 is adapted to the first embedding groove 271, and the second sealing flange 292 is adapted to the second embedding groove 281.

[0027] It is worth mentioning that the connection mode of the pulse pipes 21 and the air source is also convenient for dismounting: the other end of each pulse pipe 21 is connected with the supply pipe 23 from the air bag through a quick opening and closing fixing hoop 25. The free end of the lower hoop body 252 is hinged with a locking handle 253, and the free end of the upper hoop body 251 is provided with a bayonet 254. After the fixing hoop 25 is buckled, the locking handle 253 is pressed to be clamped into the bayonet 254, so that the locking can be realized, and the operation is very fast.

[0028] In order to ensure the sealing and reliability of the connection, during installation, a sealing ring 29 with sealing flanges on both sides is placed between the two flanges, so that the sealing flanges are clamped into the corresponding embedding grooves. When the lower hoop body 252 and the upper hoop body 251 are buckled, the semicircular grooves 255 on the inner sides will jointly form a complete limiting ring groove 256, which clamps the "sandwich" structure formed by the first connecting flange 27, the sealing ring 29 and the second connecting flange 28, plays an axial limiting and fastening role, and at the same time ensures excellent sealing performance.

[0029] As shown in Figures 9 to 10 Further, the positioning member 26 includes two mounting plates 261 fixed to the two inner walls of the clean cavity 12 respectively, and mounting holes 262 are formed in the mounting plates 261, and connecting holes 263 are correspondingly formed in the two ends of the fixing plate 22; a fastener 264 passes through the mounting holes 262 and the connecting holes 263 to fix the fixing plate 22 on the mounting plates 261.

[0030] Further, a guide gap 265 is reserved between the mounting plate 261 and the first side wall 267 of the clean cavity 12; the end of the fixing plate 22 extends perpendicularly towards the side wall and has a clamping plate 266, and the thickness of the clamping plate 266 is adapted to the width of the guide gap 265; during installation, the clamping plate 266 is adapted to be clamped into the guide gap 265 to realize the pre-positioning of the fixing plate 22, wherein the first side wall 267 is adjacent to the two inner walls of the clean cavity 12 where the mounting plates 261 are installed.

[0031] It is worth mentioning that one end of all pulse tubes 21 is fixedly connected with a connecting plate 241, and the connecting plate 241 is fixed on the fixing plate 22 by fixing bolts (fixing member 24). The two ends of the fixing plate 22 are detachably mounted on the side walls of the clean chamber 12 by positioning. Specifically, mounting plates 261 are pre-welded on the inner walls of the two sides of the clean chamber 12. The mounting plates 261 are provided with mounting holes 262, and the two ends of the fixing plate 22 are correspondingly provided with connecting holes 263. During installation, the bolts are passed through the mounting holes 262 and the connecting holes 263 and are tightened, so that the fixing plate 22 is firmly fixed.

[0032] In order to further facilitate installation and positioning, when the fixing plate 22 is installed, the clamping plates 266 at the two ends can be clamped into the corresponding guide gaps 265 respectively, so that the fixing plate 22 is pre-positioned in the horizontal direction. At this time, the connecting holes 263 and the mounting holes 262 are basically aligned, and then the bolts can be easily inserted for fastening. This design avoids the difficulty of hole operation at high altitude.

[0033] As shown in Figure 11 Further, the partition plate 40 is provided with a plurality of maintenance windows 41, each of which is detachably covered with an independent maintenance plate 42, and each of the maintenance plates 42 is provided with one or more mounting through holes 43 for mounting filter bags of the filter assembly 30; the size of the maintenance window 41 is greater than the diameter of the filter bag.

[0034] Further, the edge of the maintenance window 41 is provided with an annular sealing groove 44, and the periphery of the maintenance plate 42 is integrally extended downward with a sealing flange 45 matched with the sealing groove 44; the sealing flange 45 is detachably connected with the partition plate 40 through a plurality of locking members 46.

[0035] It is worth mentioning that the partition plate 40 is provided with a plurality of maintenance windows 41 in a rectangular array. The size of each maintenance window 41 is much larger than the diameter of a single filter bag. Each maintenance window 41 is covered with an independent and detachable maintenance plate 42 through the locking member 46. The edge of the maintenance window 41 is processed with an annular sealing groove 44, and the periphery of the maintenance plate 42 is integrally formed downward with a sealing flange 45 matched with the sealing groove 44. During installation, a sealing strip can be placed in the sealing groove 44, and then the sealing flange 45 of the maintenance plate 42 is pressed into the groove, and finally the locking member 46 such as a bolt is used to fasten the maintenance plate 42 on the partition plate 40, so as to form a reliable seal. Each maintenance plate 42 is stamped with a plurality of mounting through holes 43 for mounting filter bags of the filter assembly 30. The bag opening of the filter bag is fixed on the mounting through hole 43 through a clamp or a sealing ring 29, and the bag body is hung in the filter chamber 11. This design makes it only need to remove the corresponding maintenance plate 42 when the filter bag in a certain area needs to be replaced, which greatly facilitates maintenance.

[0036] As Figures 12 to 13 shown further, the side wall of the box 10 is provided with an air inlet 13 communicating with the filter chamber 11, the flow cross section of the air inlet 13 gradually expands along the direction from the outside of the box 10 to the inside of the filter chamber 11.

[0037] Further, a flow guide plate 14 is arranged at the air inlet 13 for guiding and homogenizing the airflow.

[0038] It is worth mentioning that the box 10 is usually welded by steel plates, and the inside is divided into the lower filter chamber 11 and the upper clean chamber 12 by a horizontally arranged partition plate 40. An air inlet 13 is arranged at the lower part of the side wall of the box 10, and an air outlet 15 is arranged at the top. Preferably, the flow cross section of the air inlet 13 is designed as a horn shape gradually expanding from the outside of the box 10 to the inside of the filter chamber 11, which helps to slow down the air inlet flow rate and make the airflow distribution more uniform. Further preferably, a plurality of flow guide plates 14 are welded at the air inlet 13 for guiding and breaking the airflow vortex that may be formed, so as to avoid local flushing of the filter bag.

[0039] A plurality of pulse pipes 21 correspond to a plurality of rows of filter bags below. The pulse pipe 21 is provided with a blow hole aligning with the bag opening of the filter bag.

[0040] Working principle: The dust-containing gas enters the filter chamber 11 through the air inlet 13 after being uniformly flowed by the flow guide plate 14, and passes through the filter bag. The dust is blocked on the outer surface of the filter bag, and the purified gas enters the clean chamber 12, and is finally discharged from the top air outlet 15. When cleaning, the pulse control instrument instructs a specific pulse valve to open, and the compressed air is sprayed from the blow hole from the air tank through the supply pipe 23 and the pulse pipe 21, a large amount of clean air enters the filter bag, so that it is inflated and shaken instantly, and the dust is shaken off to the ash bucket.

[0041] When it is necessary to replace the filter bag below a certain access plate 42, the maintenance process is as follows: Close the chamber valve to isolate the operation area.

[0042] Loosen the fixing hoop 25 corresponding to the pulse pipe 21 in the region, so that it is separated from the supply pipe 23.

[0043] Loosen the positioning member 26 at both ends of the fixed plate 22, lift and move the entire pulse pipe 21 module or a part to leave a working space.

[0044] Loosen the locking member 46 on the access plate 42 where the filter bag to be replaced is located, and remove the access plate 42.

[0045] Take out the old filter bag from the access window 41 and install a new filter bag.

[0046] In reverse order, install the maintenance plate 42, the pulse tube 21 module and connect the fixing hoop 25.

[0047] Therefore, the maintenance process is greatly simplified, and the work efficiency is improved.

[0048] It can be understood that when the filter bag needs to be disassembled, it can be directly disassembled from the corresponding installation hole 43.

[0049] In summary, the technical effects obtained by implementing the technical scheme are as follows: Through all the pulse tubes 21 integrated into a module through the fixing plate 22, and connected through the detachable positioning piece 26 and the fixing hoop 25. When the filter bag needs to be maintained, the entire pulse tube 21 module or the local pulse tube 21 can be quickly released from the fixing, which greatly avoids the operation of "disassembling one by one", so that the maintenance personnel can quickly and conveniently access the filter bag below.

[0050] Through the plurality of maintenance windows 41 and the independent maintenance plate 42 provided on the partition plate 40. This means that the maintenance personnel can only disassemble the single maintenance plate 42 directly above the filter bag that needs to be replaced, achieving "precise maintenance", without the need to operate the entire top cover or a large area as in the traditional structure. This cooperates with the pulse tube 21 module that can be quickly removed, forming a highly efficient and coordinated maintenance channel.

[0051] The pulse tube 21 is integrally fixed through the fixing plate 22, forming a rigid and stable structure, effectively preventing the displacement or loosening of the pulse tube 21 due to vibration during equipment operation, ensuring the accurate alignment of the blowing port and the center of the filter bag, thereby ensuring stable and uniform dust removal effect.

[0052] Through the cooperation structure of the flange, the sealing ring 29 and the limiting ring groove 256, not only the disassembly is facilitated, but also excellent sealing performance is provided, preventing compressed air leakage, ensuring the blowing pressure, and avoiding energy loss and equipment performance decline caused by air leakage at the connection.

[0053] Through the gradually expanding inlet 13 and the guide plate 14, it is helpful for the dust-containing gas to enter the filter chamber 11 more smoothly and uniformly, reducing the local scouring of the filter bag, prolonging the service life of the filter bag, and improving the overall filtration efficiency.

[0054] The maintenance plate 42 is cooperated with the sealing groove 44 through the sealing flange 45, and is pressed tightly through the locking piece 46, ensuring the strict sealing between the clean chamber 12 and the filter chamber 11, preventing the short circuit of the dust-containing gas into the clean gas side, and ensuring the emission standard.
