Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bag filter frames, and more specifically, it relates to a bag filter frame. Background Technology
[0002] Baghouse dust collectors are highly efficient dust removal devices. During operation, dust-laden gas enters the collector through the inlet. As the gas passes through the filter bags, the dust is trapped on the outer surface of the bags, and the purified gas passes through the filter bags and is finally discharged through the outlet. The filter bags are typically supported by a frame and mounted on a perforated plate. Existing baghouse dust collector frames are usually simply inserted into the perforated plate, a simplistic fixing method that reduces frame stability. This makes the frame prone to swaying during use, thus reducing its effective support for the filter bags. Furthermore, existing baghouse dust collector frames provide weak fixation for the filter bags, making them prone to detachment during use, which affects the normal operation of the dust removal process.

[0030] Please see Figure 1-6A bag filter frame includes an outer ring 1, with multiple fixed chambers 2 inside the outer ring 1. A screw 3 is rotatably mounted in each fixed chamber 2. A movable plate 4 is threaded onto the screw 3. Two locking blocks 5 are fixedly mounted on one side of the movable plate 4. One end of each locking block 5 passes through the fixed chamber 2 and is movably connected to a tube sheet 6. A slot 7 that mates with the tube sheet 6 is provided on one side of each locking block 5. A bevel gear 8 is fixedly mounted on the screw 3. The bevel gear 8 meshes with a bevel gear ring 9. A rotating ring 10 that is rotatably connected to the outer ring 1 is provided at the upper end of the bevel gear ring 9. The upper end of the rotating ring 10 passes through the outer ring 1 and extends to the outside of the outer ring 1. A rotating groove 11 that mates with the rotating ring 10 and the bevel gear ring 9 is provided on the outer ring 1.
[0031] An inner ring 12 is installed inside the outer ring 1. A support frame 13 is provided at the lower end of the inner ring 12. An installation ring 14 is movably connected to the lower end of the inner ring 12. A cloth bag 15 is provided at the lower end of the installation ring 14.
[0032] In this embodiment, when the entire frame needs to be installed on the tube sheet 6, the outer ring 1 is placed into the corresponding hole on the tube sheet 6, and the rotating ring 10 is rotated. The rotating ring 10 drives the conical toothed ring 9 to rotate, the conical toothed ring 9 drives the conical gear 8 to rotate, and the conical gear 8 drives the screw 3 to rotate. Since the screw 3 is threadedly connected to the moving plate 4, the moving plate 4 moves. The moving plate 4 drives the two locking blocks 5 to move, so that the locking blocks 5 are engaged with the tube sheet 6 through the locking groove 7, thereby installing the outer ring 1 onto the tube sheet 6.
[0033] More specifically, when installing the outer ring 1, the rotating ring 10 can be rotated to allow the locking block 5 to extend and lock onto the tube sheet 6. When installing the cloth bag 15, the cloth bag 15 is placed inside the outer ring 1, so that the mounting ring 14 is movably connected to the outer ring 1. The inner ring 12 is moved, so that the inner ring 12 drives the support frame 13 to move into the cloth bag 15 and installs the inner ring 12 inside the outer ring 1, so that the inner ring 12 fixes the mounting ring 14, thereby fixing the cloth bag 15 to the entire frame, and the support frame 13 supports the cloth bag 15.
[0034] Please see Figure 1-6 As one embodiment of installing the cloth bag 15: the outer ring 1 is provided with two positioning blocks 16, the outer ring 1 is provided with an installation groove 17 that cooperates with the inner ring 12 and the installation ring 14, the upper end of the inner ring 12 is recessed inward to form two installation chambers 18, each installation chamber 18 is movably provided with a fixing plate 19, the upper end of the fixing plate 19 is provided with a push plate 20, the upper end of the push plate 20 passes through the installation chamber 18 and extends to the outside of the installation chamber 18, a spring 21 is fixedly connected between one side of the fixing plate 19 and the installation chamber 18, and a fixing rod 22 is fixedly provided on the other side of the fixing plate 19, one end of the fixing rod 22 passes through the installation chamber 18 and is inserted into the outer ring 1.
[0035] Specifically, when the outer ring 1 is placed into the hole in the tube sheet 6 during installation, the two positioning blocks 16 position it. When installing the mounting ring 14, the mounting ring 14 can be placed into the mounting groove 17. The mounting ring 14 drives the cloth bag 15 into the outer ring 1, pushes the two push plates 20, and the push plates 20 drive the fixing plate 19 to move. The spring 21 is compressed, and the fixing plate 19 drives the fixing rod 22 to move into the mounting chamber 18. Then, the inner ring 12 drives the support frame 13 to be inserted into the cloth bag 15, and the inner ring 12 is moved into the mounting groove 17. The outer ring 1 has two fixing holes that cooperate with the fixing rod 22. The two fixing rods 22 are aligned with the fixing holes, and the push plates 20 are released. Under the push of the spring 21, the fixing plate 19 drives the fixing rod 22 to be inserted into the fixing holes of the outer ring 1, thereby fixing the inner ring 12.
[0036] Please see Figure 1-6 As one embodiment of fixing the rotating ring 10: a toothed belt 23 is fixedly provided on the outer side of the rotating ring 10, a support plate 24 is provided on the upper end of the outer ring 1, a bolt 25 is threaded on the support plate 24, one end of the bolt 25 passes through the support plate 24 and is rotatably connected to a fixing block 26 that engages with the toothed belt 23, and the lower end of the fixing block 26 is slidably connected to the outer ring 1 through a track structure.
[0037] Specifically, after the outer ring 1 is fixed to the tube sheet 6, when the rotating ring 10 does not need to rotate, the bolt 25 is rotated. Since the bolt 25 is threadedly connected to the support plate 24, the bolt 25 moves while rotating. The bolt 25 drives the fixing block 26 to move along the sliding connection with the outer ring 1, thereby locking the toothed belt 23 and fixing the rotating ring 10.
[0038] In summary, when using the overall equipment:
[0039] When it is necessary to install the cloth bag 15 onto the entire frame, place the cloth bag 15 inside the outer ring 1, and simultaneously place the mounting ring 14 into the mounting groove 17. Push the two push plates 20, which drive the fixing plate 19 to move. The spring 21 is compressed, and the fixing plate 19 drives the fixing rod 22 to move into the mounting chamber 18. Then, the inner ring 12 drives the support frame 13 to be inserted into the cloth bag 15, and the inner ring 12 is moved into the mounting groove 17. The outer ring 1 has two fixing holes that cooperate with the fixing rod 22. Align the two fixing rods 22 with the fixing holes, and release the push plate 20. Under the push of the spring 21, the fixing plate 19 drives the fixing rod 22 to be inserted into the fixing hole of the outer ring 1, thereby fixing the inner ring 12. The cloth bag 15 can then be fixed onto the entire frame, and the support frame 13 supports the cloth bag 15.
[0040] When the entire frame needs to be installed onto the tube sheet 6, the outer ring 1 is placed into the corresponding hole on the tube sheet 6, and the two positioning blocks 16 position it. Rotating the rotating ring 10 causes the conical gear ring 9 to rotate, which in turn causes the conical gear 8 to rotate. The conical gear 8 then causes the screw 3 to rotate. Since the screw 3 is threadedly connected to the moving plate 4, the moving plate 4 moves, causing the two locking blocks 5 to move. The locking blocks 5 then engage with the tube sheet 6 through the locking slots 7, thus installing the outer ring 1 onto the tube sheet 6.
[0041] When it is necessary to fix the rotating ring 10, after fixing the outer ring 1 to the tube sheet 6, when the rotating ring 10 does not need to rotate, rotate the bolt 25. Since the bolt 25 is threadedly connected to the support plate 24, the bolt 25 moves while rotating. The bolt 25 drives the fixing block 26 to move along the sliding connection with the outer ring 1, thereby locking the toothed belt 23 and fixing the rotating ring 10.
[0042] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
