Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, and in particular to a bag filter anti-jamming guide device. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device 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 due to gravity and fall into the ash hopper. Gas containing finer dust particles is purified by trapping the dust as it passes through the filter media. Existing baghouse dust collection systems include multiple discharge ports and ash collection points. During the conveying of dust collected by the dust collector via a screw conveyor, material accumulation easily forms in the middle section of the screw conveyor. This causes a sudden change in the compressive torque due to high-concentration dust in the middle section of the conveyor. Furthermore, the lack of a pressure relief channel in the middle section of the screw conveyor results in a screw shaft jamming rate of over 85%, requiring frequent start-ups and shutdowns for declogging. This not only increases maintenance costs but also affects the operational stability of the dust collection system. Therefore, we propose a baghouse dust collector anti-jamming and flow guiding device. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a material-preventing and flow-guiding device for baghouse dust collectors. This invention solves the problem that existing baghouse dust collector systems, which include multiple discharge ports and dust collection points, often experience material accumulation in the middle section of the screw conveyor during dust collection. This accumulation causes a sudden change in compressive torque due to the high concentration of dust in the middle section of the conveyor, and the lack of a pressure relief channel in this section results in a screw shaft jamming rate exceeding 85%. This necessitates frequent start-stop operations to clear blockages, increasing maintenance costs and affecting the operational stability of the dust collection system.

[0004] This utility model discloses an anti-jamming material guiding device for a bag filter dust collector, comprising a bag filter dust collector body, a material conveying pipe at the bottom of the bag filter dust collector body, a first motor at one end of the material conveying pipe, one end of the first motor passing through the material conveying pipe and fixedly connected to a first transmission rod, a first spiral transmission blade on the first transmission rod, a guide pipe at the lower middle of the material conveying pipe, a second motor at the lower end of the guide pipe, a rotating shaft of the second motor passing through the guide pipe and fixedly connected to a second transmission rod, a second spiral transmission blade on the second transmission rod, a discharge pipe at the side of the guide pipe near the second motor, a cover plate at the bottom of the discharge pipe, and a movably connected cover plate away from the second motor to the discharge pipe.

[0005] In the above scheme, the feeding pipe is provided with a first U-shaped seat on the side away from the second motor. The first U-shaped seat is movably connected to the hydraulic cylinder through a pin. The stroke end of the hydraulic cylinder is movably connected to the cover plate through a second U-shaped seat.

[0006] In the above scheme, the guide tube is inclined downwards, and the inclination angle of the guide tube is 40-50°.

[0007] In the above scheme, the distance between the feed pipe and the first motor is 8-10m.

[0008] In the above scheme, both the guide pipe and the discharge pipe are wear-resistant steel pipes, and the wall thickness of the guide pipe and the discharge pipe is not less than 6mm.

[0009] In the above scheme, the diameter of the guide pipe is 1.2-1.5 times the diameter of the conveying pipe.

[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides a material-blocking and flow-guiding device for a bag filter dust collector. A first motor drives a first transmission rod to rotate, which in turn drives a first spiral transmission blade to rotate. The rotating first spiral transmission blade can transport the dust processed by the bag filter dust collector body. A second motor drives a second transmission rod to rotate, which in turn drives a second spiral transmission blade to rotate. The rotating second spiral transmission blade can transport the dust in the middle of the conveying pipe. The dust transported by the second spiral transmission blade can be discharged through the discharge pipe. By setting a guide pipe and a discharge pipe in the middle of the conveying pipe, dust accumulation in the middle section of the conveyor can be effectively avoided. This material-blocking and flow-guiding device has a simple structure, facilitates dust discharge, has a good discharge effect, and can effectively prevent dust accumulation in the middle section of the conveyor, reducing the maintenance cost of the bag filter dust collector while effectively improving its service life.

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0015] like Figure 1-3 As shown, this utility model is a material-blocking and flow-guiding device for a bag filter dust collector, including a bag filter body 1. A conveying pipe 2 is located below the bag filter body 1. A first motor 3 is located at one end of the conveying pipe 2. One end of the first motor 3 passes through the conveying pipe 2 and is fixedly connected to a first transmission rod 4. Both ends of the first transmission rod 4 are movably connected to the inner wall of the conveying pipe 2. A first spiral transmission blade 5 is provided on the first transmission rod 4. When the first motor 3 is working, it drives the first transmission rod 4 to rotate, which in turn drives the first spiral transmission blade 5 to rotate. The rotating first spiral transmission blade 5 can transport the dust processed by the bag filter body 1. A guide pipe 6 is located in the middle of the lower part of the conveying pipe 2, and a second motor 7 is located at the lower end of the guide pipe 6. The rotating shaft of the second motor 7 passes through the guide pipe 6 and is fixedly connected to the second transmission rod 8. The lower end of the second transmission rod 8 is movably connected to the guide pipe 6. The second transmission rod 8 is provided with a second spiral transmission blade 9. When the second motor 7 is working, the second motor 7 drives the second transmission rod 8 to rotate, and the second transmission rod 8 drives the second spiral transmission blade 9 to rotate. The rotating second spiral transmission blade 9 can transport the dust in the middle of the conveying pipe 2. The guide pipe 6 is provided with a discharge pipe 10 on the side near the second motor 7. The dust transported by the second spiral transmission blade 9 can be discharged through the discharge pipe 10. A cover plate 11 is provided below the discharge pipe 10. The cover plate 11 can seal the bottom of the discharge pipe 10. The side of the cover plate 11 away from the second motor 7 is movably connected to the discharge pipe 10.

[0016] The feeding pipe 10 is provided with a first U-shaped seat 12 on the side away from the second motor 7. The first U-shaped seat 12 is movably connected to the hydraulic cylinder 13 through a pin. The stroke end of the hydraulic cylinder 13 is movably connected to the cover plate 11 through a second U-shaped seat 14. When the hydraulic cylinder 13 is working, the hydraulic cylinder 13 can push the cover plate 11 to rotate around the feeding pipe 10, so that the opening and closing of the cover plate 11 can be completed by the extension and retraction of the hydraulic cylinder 13.

[0017] The guide tube 6 is inclined downwards, and the inclination angle of the guide tube 6 is 40-50°. The inclined guide tube 6 makes it easier for the second spiral conveyor blade 9 to transport dust.

[0018] The distance between the feed pipe 6 and the first motor 3 is 8-10m.

[0019] Both the guide pipe 6 and the discharge pipe 10 are wear-resistant steel pipes, and the wall thickness of the guide pipe 6 and the discharge pipe 10 is not less than 6mm.

[0020] The diameter of the feed pipe 6 is 1.2-1.5 times that of the feed pipe 2.

[0021] Specifically, in this utility model, when the first motor 3 is working, it drives the first transmission rod 4 to rotate, and the first transmission rod 4 drives the first spiral transmission blade 5 to rotate. The rotating first spiral transmission blade 5 can transport the dust processed by the bag dust collector body 1. When the second motor 7 is working, it drives the second transmission rod 8 to rotate, and the second transmission rod 8 drives the second spiral transmission blade 9 to rotate. The rotating second spiral transmission blade 9 can transport the dust in the middle of the conveying pipe 2. The dust transported by the second spiral transmission blade 9 can be discharged through the discharge pipe 10. When the hydraulic cylinder 13 is working, it can push the cover plate 11 to rotate around the discharge pipe 10. Thus, the opening and closing of the cover plate 11 can be completed by the extension and retraction of the hydraulic cylinder 13. By setting the guide pipe 6 and the discharge pipe 10 in the middle of the conveying pipe 2, the accumulation of dust in the middle section of the conveyor can be effectively avoided.
