Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, and in particular to a series multi-mode baghouse dust collector. Background Technology

[0002] In industrial production, processes such as steel smelting, thermal power generation, cement manufacturing, and chemical reactions generate large amounts of dust-laden gases. Direct emissions not only cause air pollution but also harm the health of operators. Therefore, dust removal equipment is necessary to purify these dust-laden gases. Baghouse dust collectors, due to their high dust removal efficiency (interception rate of over 99% for fine particulate matter) and wide applicability to various dust types, have become one of the mainstream dust removal devices in industrial applications.

[0003] In the process of using a series multi-mode bag filter, the gas needs to be diverted through a wind box so that it can be discharged directly or discharged into another bag filter.

[0004] In existing equipment, the air box needs to be connected to multiple connecting pipes via flanges during use. When the internal parts of the air box are damaged and need to be disassembled, replaced, or repaired, multiple flange bolts need to be removed one by one. The process is cumbersome and time-consuming, which prolongs the equipment downtime and affects continuous industrial production. Therefore, we propose a series multi-mode bag filter dust collector to solve the above problems. Utility Model Content

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Example 1, as Figure 1-5 As shown, a series multi-mode bag filter dust collector includes three bag filter bodies 1. From left to right, the three bag filter bodies 1 are a primary bag filter dust collector, a secondary bag filter dust collector, and a tertiary bag filter dust collector. An auxiliary pipe 11 is installed on the top of the three bag filter bodies 1. An air box 12 is installed at the end of each pair of bag filter bodies 1 that is close to each other. An installation component 2 is provided on the outer surface of each of the two air boxes 12. A flow diversion component 3 is provided inside each of the two air boxes 12.

[0020] The aforementioned bag filter body 1 is a DMC type pulse single-unit bag filter.

[0021] Specifically, in order to achieve the goal of quickly and easily disassembling the bellows, please refer to... Figure 2 and Figure 3 In this embodiment, the two installation components 2 are arranged symmetrically to the left and right of the center of the auxiliary pipe 11. The installation component 2 includes three connecting cylinders 21, and all three connecting cylinders 21 are fixedly connected to the outer surface of the air box 12 on the same side.

[0022] Further reading Figure 3 In this embodiment, a sliding tube 22 is slidably connected to the inner wall of the connecting cylinder 21, and a sealing cylinder 221 is fixedly connected to the outer surface of the sliding tube 22 on the side away from the air box 12. Two connecting tubes 23 are installed at the bottom of the auxiliary pipe 11. Connecting tubes 23 are installed on the top right side of the three bag dust collector bodies 1. Connecting tubes 23 are installed on the left end of the two bag dust collector bodies 1 located on the right side. The outer surface of the sliding tube 22 on the side away from the air box 12 is inserted into the inner wall of the connecting tube 23 on the same side. The inner wall of the sealing cylinder 221 is inserted into the outer surface of the connecting tube 23 on the same side.

[0023] Further reading Figure 3 In this embodiment, a circular groove is provided at the end of the connecting cylinder 21 away from the air box 12, and a sliding plate 24 is slidably connected to the inner wall of the circular groove. The inner wall of the sliding plate 24 is slidably connected to the outer surface of the sliding tube 22.

[0024] Further reading Figure 3 In this embodiment, a plurality of fixing rods 241 are fixedly connected to the inner wall of the circular groove. The outer surfaces of the plurality of fixing rods 241 are slidably connected to the inner wall of the sliding plate 24. Springs 242 are sleeved on the outer surfaces of the plurality of fixing rods 241. The ends of the plurality of springs 242 away from the bellows 12 are fixedly connected to the ends of the sliding plate 24 near the bellows 12. The ends of the plurality of springs 242 near the bellows 12 are fixedly connected to the inner wall of the circular groove.

[0025] During implementation, when it is necessary to disassemble the bellows 12, first push the corresponding sealing cylinder 221 to move closer to the bellows 12. When the sealing cylinder 221 moves, it will drive the sliding tube 22 to slide in the inner wall of the connecting cylinder 21. When the sliding tube 22 slides, it will drive the sliding plate 24 to slide on the outer surface of several fixed rods 241. When the sliding plate 24 slides, it will squeeze several springs 242 to deform them. When the sliding tube 22 moves down a certain distance, its outer surface can disengage from the inner wall of the corresponding connecting tube 23. It is not necessary to install multiple flange bolts one by one. The preparation work is short and can minimize the downtime of the equipment, ensuring the continuous operation of industrial production. After the multiple sliding tubes 22 disengage from the corresponding connecting tubes 23, the bellows 12 can be removed directly by simply removing the bolts that were used to install and remove the bellows 12.

[0026] Example 2: This example sets up a splitter component based on Example 1.

[0027] Specifically, in order to achieve the goal of quickly and conveniently completing the gas flow direction conversion operation, please refer to... Figure 4 and Figure 5 In this embodiment, the two diversion components 3 are arranged symmetrically to the left and right with the center of the auxiliary pipe 11 as the center point. The diversion component 3 includes a threaded rod 31. The outer surfaces of the front and back of the threaded rod 31 are rotatably connected to the inner wall of the wind box 12 on the same side. A motor 311 is installed on the front of each of the two wind boxes 12. The front of the threaded rod 31 is fixedly connected to the output end of the motor 311 on the same side.

[0028] Further reading Figure 4 and Figure 5 In this embodiment, the outer surface of the threaded rod 31 is rotatably connected to the housing 32, the right end of the housing 32 is fixedly connected to the inner wall of the wind box 12 on the same side, and the outer surface of the threaded rod 31 is threadedly connected to the moving block 312.

[0029] Further reading Figure 5 In this embodiment, the top and bottom of the moving block 312 are fixedly connected with sliding rods 33, the top and bottom of the box body 32 are provided with sliding grooves, the outer surfaces of the two sliding rods 33 are slidably connected to the inner wall of the sliding groove on the same side, the ends of the two sliding rods 33 that are far apart from each other are fixedly connected with baffles 331, and the ends of the two baffles 331 that are far apart from each other are in close contact with the inner wall of the air box 12.

[0030] During implementation, when the device needs to directly discharge the gas after dust removal from the primary bag filter body 1, the corresponding motor 311 is turned on to drive the threaded rod 31 to rotate clockwise in the inner wall of the air box 12. When the threaded rod 31 rotates clockwise, it will drive the moving block 312 to move backward. When the moving block 312 moves, it will drive the two sliding rods 33 to slide in the inner wall of the corresponding slide groove. When the sliding rods 33 slide, they will drive the baffle 331 to move. When the two sliding rods 33 move a certain distance, the connecting cylinder 21 leading to the inner wall of the auxiliary pipe 11 will be opened, and the connecting cylinder 21 leading to the secondary bag filter body 1 will be closed. This allows for quick and convenient completion of the conversion operation, which not only avoids dust removal interruption caused by cumbersome adjustment process, but also ensures continuous purification of dust-laden gas and adapts to the dynamic changes in dust concentration in industrial production. Moreover, it eliminates the need for manual intervention in the gas passage, reducing labor costs and skill requirements.

[0031] The working principle of this utility model is as follows: When it is necessary to disassemble the bellows 12, first push the corresponding sealing cylinder 221 to move closer to the bellows 12. When the sealing cylinder 221 moves, it will drive the sliding tube 22 to slide in the inner wall of the connecting cylinder 21. When the sliding tube 22 slides, it will drive the sliding plate 24 to slide on the outer surface of several fixed rods 241. When the sliding plate 24 slides, it will squeeze several springs 242 to deform them. When the sliding tube 22 moves down a certain distance, its outer surface can disengage from the inner wall of the corresponding connecting tube 23. It is not necessary to install multiple flange bolts one by one. The preparation time is short and the equipment downtime can be minimized, ensuring continuous industrial production. After the multiple sliding tubes 22 disengage from the corresponding connecting tubes 23, the bellows 12 can be removed directly by only removing and installing the bolts of the bellows 12.

[0032] When the device needs to directly discharge the gas after dust removal from the primary bag filter body 1 during operation, the corresponding motor 311 is turned on to drive the threaded rod 31 to rotate clockwise in the inner wall of the air box 12. When the threaded rod 31 rotates clockwise, it will drive the moving block 312 to move backward. When the moving block 312 moves, it will drive the two sliding rods 33 to slide in the inner wall of the corresponding slide groove. When the sliding rods 33 slide, they will drive the baffle 331 to move. After the two sliding rods 33 have moved a certain distance, the connecting cylinder 21 leading to the inner wall of the auxiliary pipe 11 will be opened, and the connecting cylinder 21 leading to the secondary bag filter body 1 will be closed. This allows for quick and convenient completion of the conversion operation, which not only avoids dust removal interruption caused by cumbersome adjustment process, but also ensures continuous purification of dust-laden gas and adapts to the dynamic changes in dust concentration in industrial production. Moreover, it eliminates the need for manual intervention in the gas passage, reducing labor costs and skill requirements.
