[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0032] like Figure 1-5As shown, this utility model provides a quick-change bracket for filter bags in a pulse jet baghouse dust collector, including a pulse jet baghouse dust collector body 1 and quick-release mechanisms 4. The quick-release mechanisms 4 are respectively located on both sides inside the pulse jet baghouse dust collector body 1. A replacement frame 2 is provided inside the pulse jet baghouse dust collector body 1. Insert blocks 22 are provided on both sides of the lower end of the replacement frame 2. A protrusion 23 is provided on one side of each pair of insert blocks 22. Each pair of quick-release mechanisms 4 includes a fixing box 41. A top plate 44 is slidably connected inside the fixing box 41. Multiple auxiliary springs 43 are provided inside the fixing box 41. A fixing cylinder 42 is provided on one side of each fixing box 41. The connection between the fixing cylinder 42 and the fixing box 41 is interconnected. The fixed cylinder 42 has a cavity, and a pin 46 slides within the cavity. One end of the pin 46 has a pressure block 47 that extends into the fixed box 41, and the other end of the pin 46 has a handle 45. The insert 22 is inserted into the fixed box, and the bottom of the protrusion 23 on the insert 22 abuts against it. The upper end of the replacement frame 2 has lifting rings 21 at each of its four corners. The filter bag and the internal frame of the filter bag are installed through the replacement frame 2. When the filter bag needs to be replaced, the quick-release mechanism 4 is used to release the fixation of the replacement frame 2, and then the replacement frame 2 to be replaced is lifted by the lifting rings 21 fixed to the top of the replacement frame 2 by an external lifting mechanism. Then, the replacement frame 2, with clean filter bags and keel installed, is suspended inside the pulse jet bag dust collector body 1. The replacement frame 2 with new filter bags is then fixed inside the pulse jet bag dust collector body 1 via the quick-release mechanism 4. Simultaneously, the old replacement frame 2 and filter bags are cleaned for future use. This process of replacing new filter bags is faster and saves less time. In use, pull out the handles 45 on both sides of the pulse jet bag dust collector body 1 to retract the pin rod 46 and pressure block 47 into the fixed cylinder 42. Then, the replacement frame 2 with new filter bags and keel installed is lifted using an external lifting device, and the replacement frame 2 is aligned with the pulse jet bag dust collector body 1. As the main body 1 of the pulse bag dust collector descends, the insertion block 22 at the bottom of the replacement frame 2 presses into the fixing box 41, simultaneously causing the top plate 44 to press down and the auxiliary spring 43 to contract. After the pressing is completed, the staff pushes the handles 45 on both sides of the main body 1 of the pulse bag dust collector, causing the insertion pin 46 and the pressure block 47 to extend into the fixing box 41. The bottom of the pressure block 47 presses against the top of the protrusion 23, thereby fixing the replacement frame 2 with the new filter bag and keel installed inside the main body 1 of the pulse bag dust collector. This process completes the replacement. The replacement frame 2 with the old filter bag and keel installed is removed and transported to a professional space for cleaning and replacement, in preparation for the next replacement need.
[0033] An annular groove is provided at the end of the fixed cylinder 42 away from the fixed box 41, and an iron ring 49 is fixed in the annular groove. An annular groove is also provided on the side of the handle 45 that is close to the iron ring 49. A strong magnet 48 is fixed in the annular groove of the handle 45. The strong magnet 48 is attracted to the iron ring 49. Through holes 13 are provided on both sides of the pulse bag dust collector body 1. The fixed cylinder 42 and the handle 45 extend to the external space through the through holes 13. The strong magnet 48 of the handle 45 is attracted to the iron ring 49 of the fixed cylinder 42, thereby fixing the handle 45 and the components fixed to the handle 45. This prevents the handle 45 and the components fixed to the handle 45 from being shaken off by the vibration generated during the operation of the dust collector. The fixed cylinder 42 and the handle 45 extend to the external space through the through holes 13 so that the staff can pull the handle 45.
[0034] The inner wall of the pulse jet bag filter body 1 is provided with four corner abutments 3, and the upper end of each abutment 3 is provided with a rubber pad 31. When the replacement frame 2 is installed inside the pulse jet bag filter body 1, its bottom is held in place by the rubber pad 31. An observation window 12 is provided on one side of the pulse jet bag filter body 1. The observation window 12 is encapsulated by an explosion-proof PC board. A protective cover 11 is hinged to the top of the pulse jet bag filter body 1. The abutments 3 and the rubber pads 31 hold the replacement frame 2, which is equipped with filter bags and a frame, in place, thus providing auxiliary positioning and facilitating the fixing of the replacement frame. The rubber pad 31 is fixed to the replacement frame 2, and at the same time, it contacts the replacement frame 2. When the dust collector is working, it plays a certain role in reducing the noise generated by vibration. The staff can observe the working condition inside the pulse bag dust collector body 1 through the observation window 12 and replace the filter bag in time. When the pulse bag dust collector body 1 is working, the protective cover 11 is covered. The protective cover 11 can form a sealing barrier by closing it, preventing heavy metal dust and splashing slag particles in the workshop environment from falling into the pulse bag dust collector body 1, and avoiding the blockage of precision parts such as the blow pipe and tube sheet holes by impurities.
[0035] Specifically, the working principle of this pulse jet bag filter bag quick-change bracket is as follows: When in use, pull out the handles 45 on both sides of the pulse jet bag filter body 1 to retract the pin rod 46 and pressure block 47 into the fixed cylinder 42. Then, the replacement bracket 2, with the new filter bag and frame installed, is lifted by an external lifting device. The replacement bracket 2 is then lowered, aligned with the pulse jet bag filter body 1. During descent, the bottom of the replacement bracket 2 presses into the fixed box 41, simultaneously causing the top plate 44 to press down and the auxiliary spring 43 to retract. After pressing down, the operator... The operator pushes the handles 45 on both sides of the pulse bag dust collector body 1, causing the pin rod 46 and pressure block 47 to extend into the fixing box 41. The bottom of the pressure block 47 abuts against the top of the protrusion 23, thereby fixing the replacement frame 2 with the new filter bag and keel installed inside the pulse bag dust collector body 1. This process completes the replacement. The replacement frame 2 with the old filter bag and keel installed is removed and transported to a professional space for cleaning and replacement, in preparation for the next replacement need. The strong magnet 48 of the handle 45 is used to attract the filter bag to the iron ring 49 of the fixing cylinder 42. This secures the handle 45 and the components fixed to it, preventing vibrations from the dust collector during operation from dislodging them. The fixing cylinder 42 and the handle 45 extend to the external space through the through hole 13, making it easy for workers to pull the handle 45. The abutment block 3 and the rubber pad 31 abut against the replacement frame 2, which has the filter bag and frame installed, providing auxiliary positioning and facilitating the fixing of the components to the replacement frame 2. At the same time, the rubber pad 31 contacts the replacement frame 2, providing some pressure relief during dust collector operation. The noise generated during low vibration is mitigated. Workers can observe the internal workings of the pulse jet baghouse dust collector 1 through the observation window 12, allowing for timely filter bag replacement. When the pulse jet baghouse dust collector 1 is in operation, the protective cover 11 is closed, forming a sealed barrier to prevent heavy metal dust and splashing particles from the workshop environment from falling into the interior of the pulse jet baghouse dust collector 1. This also prevents precision components such as the blowpipe and tube sheet holes from being clogged by impurities. This invention effectively improves the filter bag replacement speed and has high practical value.
