Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector blowpipes, and in particular to a dust collector blowpipe device. Background Technology
[0002] During industrial production, a large amount of dust is generated along the production process, which not only pollutes the production environment and affects product quality, but may also endanger the health of operators. As a highly efficient dust removal device, baghouse dust collectors use a dust collection fan to drive dust-laden gas into the dust chamber inside the dust collector. The air becomes clean after passing through the filter bags and is discharged by the dust collection fan, while the dust is trapped and adsorbed on the outer surface of the filter bags. Then, a pulse valve controls the injection of high-pressure gas into the filter bags to shake the dust off and into the collection hopper for the next step of the process.
[0003] The connection between the blow-off pipe and the conveying pipe often results in gaps due to factors such as installation accuracy, thermal expansion and contraction of the pipe, and long-term vibration, leading to air leakage. This causes high-pressure gas to leak during blow-off, resulting in insufficient blow-off pressure and an inability to effectively shake off dust from the filter bags, thus reducing dust collection efficiency. To address these issues, a blow-off pipe device for a dust collector is proposed. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a dust collector blowpipe device, including a blowpipe 1 for conveying high-pressure gas to shake off dust adsorbed on the outer surface of a filter bag. A conveying pipe 2 is provided on the inner wall of the blowpipe 1 for conveying high-pressure gas to the blowpipe 1. A connecting mechanism is provided at the connection between the blowpipe 1 and the conveying pipe 2. The connecting mechanism includes a connecting component and a fixing component. The connecting component includes a fixing frame 31, which is located outside the conveying pipe 2 and the blowpipe 1. A fixing frame 32 is rotatably connected to the rear of the fixing frame 31. The fixing frames 31 and 32 are used to fix the sealing gaskets 33 and 34, thereby sealing the connection between the blowpipe 1 and the conveying pipe 2 to prevent gas leakage. To improve the working efficiency of the dust collector, a sealing gasket 33 is provided on the inner wall of the first fixed frame 31, and a sealing gasket 34 is provided on the inner wall of the second fixed frame 32. The sealing gasket 33 and the sealing gasket 34 are attached to the outside of the blowing pipe 1 and the conveying pipe 2. The sealing gasket 33 and the sealing gasket 34 are used to seal the connection between the blowing pipe 1 and the conveying pipe 2. The outer side of the sealing gasket 33 and the sealing gasket 34 is provided with anti-slip protrusions, which can increase the sealing between the blowing pipe 1 and the conveying pipe 2, thereby improving the working efficiency of the dust collector. The front inner wall of the first fixed frame 31 and the second fixed frame 32 are rotatably connected with rotating columns 35 for supporting bolts 36. The inner wall of the rotating column 35 is threaded with bolts 36. By rotating the bolts 36, the first fixed frame 31 and the second fixed frame 32 can be fixed together.
[0033] Reference Figure 4 - Figure 6The fixing component includes a fixing block 41, which is fixedly connected to the outside of the rotating column 35 on the fixing frame 31. The fixing block 41 provides an installation base for the limiting member 42 and the moving member 44, serving as a connection and support. The fixing block 41 is slidably connected to the inner wall of the rotating column 35 by the limiting member 42. The limiting member 42 is L-shaped, with an arc surface on the side near the bolt 36 and an inclined surface at the top. Under the elastic force of the compression spring 43, it engages with the inner wall of the limiting groove 47 on the outside of the bolt 36, preventing the bolt 36 from loosening and enhancing the stability of the connection. The outside of the limiting member 42 is elastically connected to the fixing block 41 via the compression spring 43, providing support for the limiting member 42. The elastic force is provided to maintain the thrust towards the bolt 36 limiting groove 47, ensuring that the limiting part 42 can be tightly engaged in the limiting groove 47, effectively preventing the bolt 36 from loosening under vibration, ensuring the reliability of the connection, and improving the working efficiency of the dust collector. The upper inner wall of the limiting part 42 is slidably connected to the moving part 44, which can slide up and down on the inner wall of the limiting part 42. Under the magnetic force of the magnet 46, it is engaged in the slot 45, which can limit the limiting part 42. At the same time, by pulling the moving part 44, the limiting part 42 can be moved to release the bolt 36 from the limit, which is convenient for disassembly and maintenance of the device. The moving part 44 slides on the inner wall of the fixed block 41.
[0034] Reference Figure 5 and Figure 6 The upper part of the fixed block 41 is provided with a slot 45. There are two sets of slots 45, which are used to limit the movement of the moving part 44, so as to facilitate the maintenance operation of the device. The inner wall of the slot 45 is fixedly connected to the outer side of the moving part 44 with a magnet 46. The moving part 44 is attracted by magnetic force, so that the position of the moving part 44 within the fixed block 41 is stable, and the limiting part 42 is limited. The outer side of the bolt 36 is provided with a limiting groove 47. The limiting part 42 is engaged with the inner wall of the limiting groove 47, and cooperates with the limiting part 42 to provide a locking position for the limiting part 42, restricting the rotation of the bolt 36, preventing it from loosening, ensuring the tight connection between the first fixed frame 31 and the second fixed frame 32, and thus ensuring the connection stability of the conveying pipe 2 and the blowing pipe 1.
[0035] Reference Figure 3 and Figure 4An auxiliary component is provided on the outside of the fixed frame 31. The auxiliary component includes a mounting groove 51, which is located at the lower part of the fixed frame 31 and the upper part of the fixed frame 32. The sealing gasket 33 and the sealing gasket 34 are engaged in the inner wall of the mounting groove 51 to secure the sealing gasket 33 and the sealing gasket 34, which facilitates the installation and fixation of the sealing gaskets and ensures that the sealing gaskets are accurately positioned during use and will not shift, thereby ensuring the sealing effect. At the same time, it is easy to disassemble during maintenance and replacement. A sealing strip 53 is provided at the lower part of the sealing gasket 33 near the connection of the sealing gasket 34, and a groove 52 is provided at the upper part of the sealing gasket 34 near the connection of the sealing gasket 33. The sealing strip 53 is inserted into the inner wall of the groove 52, which further enhances the sealing performance between the sealing gasket 33 and the sealing gasket 34 and effectively prevents the blown gas from leaking from the connection between the two sealing gaskets.
[0036] Working principle: During use and installation, first insert sealing gasket 33 and sealing gasket 34 into the mounting grooves 51 on the inner walls of fixing frame 31 and fixing frame 32 respectively. Then, place fixing frame 31 and fixing frame 32 on the outside of the connection between the conveying pipe 2 and the blowing pipe 1. Next, rotate the bolt 36 on the rotating column 35 to gradually bring fixing frame 31 and fixing frame 32 closer together and tighten them. Under the pressure of the fixing frames, sealing gasket 33 and sealing gasket 34 are tightly attached to the outside of the pipe. The anti-slip convex strips on the outside of sealing gasket 33 and sealing gasket 34 increase the friction with the pipe, making the seal more stable. The sealing strip 53 and the groove 52 are interlocked, further enhancing the sealing effect, thereby effectively preventing air leakage at the pipe connection.
[0037] Under the elastic force of the compression spring 43, the limiting member 42 on the fixed block 41 is inserted into the limiting groove 47 on the outside of the bolt 36 on one side of its arc surface. Even if vibration occurs during the blowing process, the limiting member 42 can restrict the bolt 36 from rotating, prevent the first fixed frame 31 and the second fixed frame 32 from loosening, ensure the connection between the blowing pipe 1 and the conveying pipe 2 is stable, and ensure the operating efficiency of the dust collector.
[0038] When maintenance is required, pull the movable part 44 upward. The movable part 44 slides on the inner wall of the fixed block 41, overcoming the attraction force of the magnet 46 and driving the limiting part 42 to move. Then pull the movable part 44 away from the pipe, causing the limiting part 42 to disengage from the limiting groove 47 of the bolt 36. At this time, the bolt 36 can be rotated to open the first fixed frame 31 and the second fixed frame 32, which facilitates the inspection and replacement of components such as gaskets. The mounting groove 51 facilitates the disassembly and installation of gaskets, reducing maintenance difficulty, maintenance time and cost.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
