Technical Field
[0001] This utility model relates to the technical field of pulse jet pipes for dust collectors, specifically to a pulse jet pipe for a bag filter dust collector with a diversion groove. Background Technology
[0002] The blowpipe of a large-scale pulse jet baghouse dust collector is one of the core components of the pulse jet system. The blowpipe has several nozzles, with a row of filter bags positioned directly above each nozzle. Each blowpipe is connected to a pulse valve core on the air distribution box, providing pulse jet airflow for filter bag cleaning. Each blowpipe is fixed inside the dust collector using a fixing device.
[0003] However, traditional pulse jet pipes lack a dedicated material integration and guiding structure, which can lead to material scattering and uneven distribution before entering the pipe. This results in unstable material transport during subsequent pulse jetting, reducing the contact efficiency between the dust collection medium and the filter bag. It can also cause local blockage of the pipe due to material accumulation. Furthermore, the feed rate adjustment mechanism of existing pulse jet pipes is not well designed, with some using a single valve control, resulting in low adjustment accuracy and an inability to flexibly adjust the feed rate according to different operating conditions of the dust collector. Therefore, those skilled in the art provide a pulse jet pipe for baghouse dust collectors with a diversion groove to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this utility model is to provide a pulse jet pipe for a bag filter dust collector with a flow channel, so as to solve the problems mentioned in the background art above.
[0005] This utility model provides the following technical solution: a pulse jet pipe for a bag filter dust collector with a flow channel, comprising a jet pipe body, an adjusting valve for adjusting the material flow rate fixedly connected to the upper end of the jet pipe body, a flow channel for guiding the flow fixedly connected to the end of the adjusting valve away from the jet pipe body, a material collection assembly for collecting materials provided at the end of the flow channel away from the adjusting valve, and an opening and closing mechanism for adjusting the feeding rate provided in the inner cavity of the upper end of the material collection assembly.
[0006] As a preferred embodiment of the above technical solution, the material collection assembly includes a material collection frame, which is fixedly connected to the end of the drainage pipe away from the regulating valve. The inner cavity of the material collection frame is provided with a drainage slot that penetrates the inner cavity of the drainage pipe.
[0007] As a preferred embodiment of the above technical solution, the opening and closing mechanism includes a base plate, which is fixedly connected to the inner cavity of the upper end of the collecting frame. A connecting plate is fixedly connected to the center of the inner cavity of the base plate. A number of symmetrically arranged guide grooves are opened at the center of the connecting plate near the edge, and the number of symmetrically arranged guide grooves are all arc-shaped.
[0008] As a preferred embodiment of the above technical solution, the inner cavity of the guide groove is slidably connected with an opening and closing blade, the opening and closing blade is slidably connected to the guide groove via a guide rail, the upper end of the opening and closing blade is fixedly connected with a movable shaft, and several sets of the opening and closing blade and the movable shaft are symmetrically arranged.
[0009] As a preferred embodiment of the above technical solution, a number of symmetrically arranged movable shafts are slidably connected to the outer surfaces of movable plates, and the inner diameter of the movable plates is the same as the inner diameter of the connecting plates. An adjusting rod for adjusting the opening and closing angle of multiple sets of opening and closing blades is fixedly connected to the upper end of the movable shaft.
[0010] As a preferred embodiment of the above technical solution, a number of equidistant reinforcing rings are fixedly connected to the lower outer surface of the blowpipe body. The inner diameter of the reinforcing rings is adapted to the outer diameter of the blowpipe body, and the material of the reinforcing rings is wear-resistant stainless steel.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention features an opening and closing mechanism, which is stably connected to the material collection frame via a base plate. The arc-shaped guide groove on the connecting plate precisely limits the sliding trajectory of the opening and closing blades, and works with the guide rail to achieve smooth blade movement. With the help of the adjusting rod, the movable shaft and movable plate can be moved synchronously, thereby driving multiple sets of symmetrical opening and closing blades to adjust the opening and closing angle. This not only allows for flexible and precise control of the feeding rate to adapt to the material requirements under different working conditions, but also ensures the coaxiality of the movable shaft movement through the matching of the inner diameters of the movable plate and the connecting plate, ensuring a stable and reliable adjustment process and avoiding the impact of adjustment deviations on the material transmission rhythm.
[0012] Based on the aforementioned beneficial effects, the blowpipe body of this utility model serves as the core conveying component. Its outer surface features wear-resistant stainless steel reinforcing rings, whose inner diameter matches and is equidistantly distributed with the outer diameter of the blowpipe body. This not only enhances the overall structural strength of the pipeline and prevents deformation during long-term use, but also extends its service life due to its wear-resistant properties. The regulating valve can flexibly adjust the material flow rate according to actual needs, avoiding excessively fast or slow flow rates that could affect dust removal efficiency. The diversion pipe effectively guides the material, working in conjunction with the collection frame and diversion slot of the collection assembly to achieve centralized collection and stable transmission of materials, reducing material spillage and improving the overall stability and efficiency of material transmission.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] Please see Figures 1-4 As shown, this utility model provides a technical solution: a pulse jet pipe for a bag filter dust collector with a diversion groove, including a jet pipe body 1, an adjusting valve 2 for adjusting the material flow rate fixedly connected to the upper end of the jet pipe body 1, a diversion pipe 3 for diverting flow fixedly connected to the end of the adjusting valve 2 away from the jet pipe body 1, a material collection assembly 4 for collecting materials provided at the end of the diversion pipe 3 away from the adjusting valve 2, and an opening and closing mechanism 5 for adjusting the feeding rate provided in the inner cavity of the upper end of the material collection assembly 4.
[0017] The material first enters the collecting component 4 for integration, and then is transported by the collecting component 4 to the diversion pipe 3. The diversion pipe 3 guides the material flow to the regulating valve 2. The regulating valve 2 can adjust the material flow rate according to the requirements. After the flow rate is adjusted, the material is finally transported to the subsequent processing stage through the blow pipe body 1. At the same time, the opening and closing mechanism 5 of the upper inner cavity of the collecting component 4 can control the feeding rate by adjusting its own state to adapt to the overall material transmission and processing rhythm.
[0018] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the material collection assembly 4 includes a material collection frame 41, which is fixedly connected to the end of the drainage pipe 3 away from the regulating valve 2. The inner cavity of the material collection frame 41 is provided with a drainage slot 42 that penetrates the inner cavity of the drainage pipe 3.
[0019] The material collection component 4 is fixedly connected to the drainage pipe 3 through the material collection frame 41, and the drainage slot 42 penetrates the inner cavity of both, which can efficiently integrate and guide materials, reduce the scattering of materials during the transmission process, and improve the stability of material collection and transportation.
[0020] As one implementation method in this embodiment, please refer to Figures 1-4As shown, the opening and closing mechanism 5 includes a base plate 51, which is fixedly connected to the inner cavity of the upper end of the collection frame 41. A connecting plate 52 is fixedly connected to the center of the inner cavity of the base plate 51. A number of symmetrically arranged guide grooves 53 are opened at the center of the connecting plate 52 near the edge, and the number of symmetrically arranged guide grooves 53 are all arc-shaped.
[0021] In the opening and closing mechanism 5, the base plate 51 is fixed in the upper inner cavity of the material collection frame 41, and the arc-shaped guide groove 53 on the connecting plate 52 can accurately limit the sliding direction of the opening and closing blade 54, ensuring the stability of the blade movement trajectory and providing a reliable structural basis for subsequent adjustment of the feeding rate.
[0022] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, the inner cavity of the guide groove 53 is slidably connected to the opening and closing blade 54. The opening and closing blade 54 is slidably connected to the guide groove 53 through the guide rail. The upper end of the opening and closing blade 54 is fixedly connected to the movable shaft 55. Several sets of opening and closing blades 54 and movable shafts 55 are symmetrically arranged.
[0023] The guide groove 53 and the opening and closing blade 54 are slidably connected by the guide rail. With the symmetrically arranged movable shaft 55, the opening and closing blade 54 can move flexibly, making it convenient to adjust the opening and closing state according to actual needs, thereby accurately controlling the feed amount and adapting to the feeding needs under different working conditions.
[0024] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, a number of symmetrically arranged movable shafts 55 have movable plates 56 slidably connected to their outer surfaces, and the inner diameter of the movable plates 56 is the same as the inner diameter of the connecting plate 52. The upper end of the movable shafts 55 is fixedly connected to an adjusting rod 57 for adjusting the opening and closing angle of multiple sets of opening and closing blades 54.
[0025] The movable plate 56, which is slidably connected to the outer surface of the movable shaft 55, has the same inner diameter as the connecting plate 52, which can ensure the coaxiality of the movable shaft 55 when it moves. Then, the opening and closing angles of multiple sets of opening and closing blades 54 can be adjusted synchronously through the adjusting rod 57, so as to achieve convenient and unified control of the feeding rate and higher operating efficiency.
[0026] As one implementation method in this embodiment, please refer to Figure 1 As shown, a number of equidistant reinforcing rings are fixedly connected to the lower outer surface of the blowpipe body 1. The inner diameter of the reinforcing rings is matched with the outer diameter of the blowpipe body 1, and the material of the reinforcing rings is wear-resistant stainless steel.
[0027] Multiple sets of equidistant reinforcing rings on the lower outer surface of the blowpipe body 1, with inner diameters that match the outer diameter of the blowpipe body 1, can enhance the overall structural strength of the blowpipe. Furthermore, the wear-resistant stainless steel material can improve the wear resistance of the blowpipe, extend its service life, and adapt to the long-term operating environment of the dust collector.
[0028] Working principle: The material first enters the collection frame 41 of the collection component 4, and through the inner cavity of the collection frame 41 to the inner cavity of the diversion pipe 3, the material is collected and guided, so that the material enters the diversion pipe 3 stably. The diversion pipe 3 further guides the material to the regulating valve 2 connected to it. The regulating valve 2 can adjust its own structure to precisely control the flow rate of the material in the pipe according to the actual processing needs of the bag filter dust collector. After the flow rate is regulated, the material then enters the blowpipe body 1 and is transported to the corresponding processing position inside the dust collector through the blowpipe body 1, completing the material transfer and subsequent dust removal operation. When the opening and closing mechanism 5 of the upper inner cavity of the material collection component 4 is working, the operator can move the movable shaft 55 fixedly connected to the adjusting rod 57 by manipulating the adjusting rod 57. Since the movable shaft 55 is slidably connected to the movable plate 56 and the inner diameter of the movable plate 56 is the same as the inner diameter of the connecting plate 52, the movement of the movable shaft 55 will synchronously drive the movable plate 56 to move smoothly. At the same time, the opening and closing blades 54 connected to the lower end of the movable shaft 55 will slide precisely along the guide rail in the arc-shaped guide groove 53 opened on the edge of the connecting plate 52. By adjusting the sliding position of multiple sets of symmetrically arranged opening and closing blades 54 in the guide groove 53, the opening and closing angle between the blades can be changed, thereby achieving precise control of the material feeding rate into the material collection frame 41, ensuring that the feeding amount is compatible with the flow rate adjustment of the subsequent regulating valve 2 and the material conveying rhythm of the blow pipe body 1, and ensuring the stability and efficiency of the overall material transmission process.
[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
