Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bag dust collectors, and specifically relates to a bag dust collector with a quick filter bag replacement function. Background Technology
[0002] A baghouse dust collector is a dry dust filtration device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle down due to gravity and fall into the ash hopper. The gas containing finer dust particles is purified as it passes through the filter media, as the dust is trapped.
[0003] According to Chinese Patent No. CN220443382U, a protective bag filter is disclosed, including a bag filter body, a dust removal mechanism, a climbing mechanism, and a protective mechanism. The dust removal mechanism is located on the inner and outer sides of the bag filter body, the climbing mechanism is located at the outer end of the bag filter body, and the protective mechanism is located at the outer end of the bag filter body. The protective mechanism includes a fixed frame, a sliding groove, a slider, a mounting frame, an elastic fall protection net, and support legs. Through the structural design of the protective mechanism, when climbing to a high place, the mounting frame is pushed backward first, so that the slider slides backward along the sliding groove, leaving space for climbing. After climbing to the climbing ladder, the mounting frame is pushed back to its original position. There is also a limit block at the bottom of the slider to prevent the slider from disengaging from the sliding groove. In the event of an operator accidentally falling from a height, the elastic fall protection net can provide protection and cushioning for the operator.
[0004] As can be seen from the above structure, it is easy to climb. After climbing to the climbing ladder, the mounting frame can be pushed back to its original position. There is also a limit block at the bottom of the slider to prevent the slider from falling out of the groove. In the event of an operator accidentally falling from a height, the elastic fall protection net can protect and cushion the operator. Existing bag dust collectors usually use a whole lower dust collection box for filter bag filtration. If one of the filter bags is damaged, it can only be replaced by opening the top cover and pulling out the whole bag. This replacement method prolongs the maintenance time of the bag dust collector and reduces work efficiency. Utility Model Content

The connecting component 2 includes an insertion frame 21 located at the upper end of the bag mounting plate 1. Snap-fit holes 22 are provided on both sides of the insertion frame 21. The bag body 3... A plug-in block 23 is fixedly connected to the upper circumference of the plug-in block 23. Circular grooves 24 are opened on both sides of the plug-in block 23. A snap-fit spring 25 is fixedly connected inside the circular groove 24. A snap-fit connector 26 is fixedly connected to the other end of the snap-fit spring 25. The snap-fit connector 26 and the snap-fit hole 22 snap-fit with each other. The lower end of the moving screw 42 is threadedly connected to a limit plate 6. An installation screw 7 is fixedly connected to the upper end of the limit plate 6. An installation screw hole is opened at the lower end of the moving screw 42. The installation screw 7 and the installation screw hole are threadedly connected to each other.
[0024] refer to Figure 1 The moving component 4 includes moving motors 41 disposed on both sides of the upper end of the bag mounting plate 1. The output shaft of the moving motor 41 passes through the bag mounting plate 1 and is fixedly connected to a moving screw 42. The outer surface of the moving screw 42 is threadedly connected to a threaded part 43, and the inner side of the threaded part 43 is fixedly connected to a fixing plate 44. The upper end of the fixing plate 44 is fixedly connected to the cleaning component 5. When cleaning, the moving motor 41 is started to rotate the moving screw 42, and the fixing plate 44 is moved under the action of the threaded part 43, thereby enabling the cleaning component 5 to move. This allows the cleaning component 5 to move outside the bag body 3, thereby achieving a comprehensive cleaning effect on the bag body 3.
[0025] refer to Figure 1 and Figure 3The cleaning assembly 5 includes a support plate 51 mounted on the upper end of a fixed plate 44. A transmission worm gear 52 is rotatably connected to the inner side of the support plate 51. A support 53 is fixedly connected to the upper end of the fixed plate 44, and the support 53 and the transmission worm gear 52 are rotatably connected to each other. A cleaning motor 54 is fixedly connected to the upper end of the fixed plate 44. A reversing gearbox 55 is fixedly connected to the output shaft of the cleaning motor 54. The output shaft of the reversing gearbox 55 is fixedly connected to the transmission worm gear 52. A plurality of rotating slots 57 are provided on the upper end of the fixed plate 44. A rotating cylinder 58 is rotatably connected inside the rotating slots 57. The rotating cylinder 58 is fixed inside. A cleaning brush 59 is connected to the bag body 3, which is located inside a rotating cylinder 58. A transmission worm gear 56 is fixedly connected to the upper end of the rotating cylinder 58, and the transmission worm gear 56 is meshed with the transmission worm 52. By controlling the cleaning motor 54 to start, the reversing gear box 55 is driven to rotate. The rotation of the reversing gear box 55 drives the transmission worm 52 to rotate. Since the transmission worm 52 is meshed with the transmission worm gear 56, the rotating cylinder 58 is driven to rotate under the action of the transmission worm 52, which in turn drives the cleaning brush 59 to rotate, thereby cleaning the bag body 3.
[0026] refer to Figure 4 Both sides of the insertion frame 21 are fixedly connected with release springs 9, and the other end of the release springs 9 is fixedly connected with release pressure plates 10. The inner side of the release pressure plates 10 is fixedly connected with release blocks 11, and release blocks 11 are inserted into the snap-fit holes 22. At the same time, when disassembling, pressing the release pressure plates 10 causes the release blocks 11 to move into the snap-fit holes 22, thereby squeezing the snap-fit connectors 26 out of the snap-fit holes 22, thus making it easier to disassemble the bag body 3.

[0028] Operating principle and advantages: First, the bag body 3 is installed by inserting the plug 23 into the plug frame 21. During insertion, the snap-fit connector 26 is squeezed into the circular groove 24. After the plug 23 is fully inserted into the plug frame 21, the position of the snap-fit hole 22 is aligned with the position of the circular groove 24. At this time, the snap-fit connector 26 will pop out of the circular groove 24 under the action of the snap-fit spring 25, so that the snap-fit connector 26 and the snap-fit hole 22 can be snapped together, thus achieving the snap-fit effect. After installation, normal use can be achieved. During long-term use, when cleaning the bag body 3, the cleaning motor 54 is started, which drives the reversing gear box 55 to rotate. The rotation of the reversing gear box 55 drives the transmission worm gear 52 to rotate. 2 is meshed with the transmission worm gear 56, so that the rotating cylinder 58 is driven to rotate under the action of the transmission worm 52, which in turn drives the cleaning brush 59 to rotate, thereby cleaning the bag body 3. At the same time, during cleaning, the moving motor 41 is started to rotate the moving screw 42, and the fixed plate 44 is moved under the action of the threaded part 43, thereby moving the cleaning component 5. This allows the cleaning component 5 to move outside the bag body 3, thus achieving a comprehensive cleaning effect on the bag body 3. When disassembling, pressing the release plate 10 causes the release block 11 to move into the snap-fit hole 22, thereby squeezing the snap-fit connector 26 out of the snap-fit hole 22, thus facilitating the disassembly of the bag body 3.
