Technical Field

[0001] This invention belongs to the field of boiler technology, specifically a waste heat boiler vibration ash removal device. Background Technology

[0002] A waste heat boiler is a type of boiler that utilizes waste heat generated during industrial production to produce steam or hot water. The pressurized steam produced can be used as an auxiliary energy source for heating, gas supply, power generation, and other purposes. The use of waste heat boilers can effectively improve the overall utilization rate of thermal energy and reduce energy loss.

[0003] When the flue gas carrying residual heat passes through the boiler, the pulverized coal burns in a suspended state in the boiler pipes. Most of the combustibles in the coal can be burned off in the furnace, while a large amount of non-combustibles in the pulverized coal are mixed in the high-temperature flue gas and eventually form spherical particles.

[0004] During boiler operation, the non-combustible materials in pulverized coal can easily adhere to the inner wall of boiler pipes, causing blockages and reducing the internal airflow. This affects the heating effect of the waste heat boiler and may eventually lead to the risk of boiler pipe explosion.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figures 1 to 2As shown in the embodiment of the present invention, a waste heat boiler vibration cleaning device includes a boiler body 1; multiple support frames 2 are fixedly connected to the bottom of the boiler body 1; a fixing flange 4 is fixedly connected to the side wall of the boiler body 1; the fixing flange 4 is provided on both sides of the boiler body 1; a boiler pipe 3 is provided on the side of the boiler body 1; a fixing flange 4 is fixedly connected to the end of the boiler pipe 3; the fixing flange 4 at the end of the boiler pipe 3 is fixed to the fixing flange 4 on the side wall of the support frame 2 by bolts; a mounting cover 5 is fixedly connected to the top of the boiler pipe 3; a drive assembly 6 is fixedly connected to the side wall of the mounting cover 5; the drive assembly 6 can be a servo motor; a rotating shaft 7 is fixedly connected to the output end of the drive assembly 6; multiple striking plates 8 are fixedly connected to the side wall of the rotating shaft 7, and the striking plates 8 are arranged in a circular array on the side wall of the rotating shaft 7. A collection component is installed at the bottom of the boiler pipe 3. The collection component can collect the coal dust particles shaken off by the tapping. During operation, as the flue gas enters the boiler body 1 through the boiler pipe 3, the coal dust particles carried in the flue gas will adhere to the side wall of the boiler pipe 3. At this time, the drive component 6 can be activated, causing the drive component 6 to drive the rotating shaft 7 to rotate, which in turn causes the rotating shaft 7 to drive the tapping plate 8 to rotate. The vibration of the tapping plate 8 hitting the side wall of the boiler pipe 3 can shake off the coal dust particles on the side wall of the boiler pipe 3, thereby making the inner side wall of the boiler pipe 3 cleaner. This effectively avoids the situation where coal dust particles adhere to the inner side wall of the boiler pipe 3, resulting in poor ventilation of the boiler pipe 3. At the same time, the coal dust particles fall into the inside of the collection component for collection, making the cleaning of coal dust particles more convenient.

[0030] like Figure 2 As shown, the striking plate 8 is arc-shaped; a deflector plate 9 is rotatably connected to the end of the striking plate 8; the shape of the deflector plate 9 corresponds to that of the striking plate 8; the concave surfaces of the striking plate 8 and the deflector plate 9 face the direction of rotation of the deflector plate 9; a torsion spring is installed at the pivot of the deflector plate 9; during operation, when the drive assembly 6 drives the rotating shaft 7 to rotate, causing the striking plate 8 to strike the side wall of the boiler pipe 3, the deflector plate 9, when striking the surface of the boiler pipe 3, reduces the likelihood of breakage during the impact. Furthermore, the arc-shaped striking plate 8 and deflector plate 9 reduce the shaking of the deflector plate 9 when striking the surface of the boiler pipe 3, thus improving the striking effect of the striking plate 8 and deflector plate 9 on the boiler pipe 3.

[0031] like Figures 2 to 4As shown, the collection assembly includes a placement rack 10; the placement rack 10 is fixed to the bottom of the boiler pipe 3; a collection drawer 11 is slidably connected inside the placement rack 10; the placement rack 10 is positioned at the bottom of the corresponding mounting cover 5; the positions of the placement rack 10 and the mounting cover 5 are symmetrically arranged; during operation, when the side wall of the boiler pipe 3 is struck, causing coal dust particles on the inner side wall of the boiler pipe 3 to fall, the coal dust particles will fall into the inside of the collection drawer 11, and can then be collected through the collection drawer 11. When it is necessary to clean the coal dust particles, the collection drawer 11 can be pulled out to remove the collected coal dust particles, thus making the handling of coal dust particles more convenient.

[0032] like Figures 4 to 5 As shown, a fixed magnetic block 12 is fixedly connected to the bottom of the collection drawer 11; a fixed magnetic block 12 is fixedly connected to the inside of the placement rack 10; the two fixed magnetic blocks 12 are arranged to attract each other; the positions of the two fixed magnetic blocks 12 are arranged to correspond to each other; during operation, when the collection drawer 11 is placed inside the placement rack 10, the mutual attraction of the two fixed magnetic blocks 12 makes the collection drawer 11 more stable inside the placement rack 10, thus making the collection effect of the collection drawer 11 on coal powder particles better.

[0033] like Figure 6 As shown, the collection drawer 11 is internally connected to a plurality of anti-wear wheels 13; the anti-wear wheels 13 are located near the bottom of the collection drawer 11; the placement rack 10 has wheel grooves inside; the anti-wear wheels 13 are arranged correspondingly to the wheel grooves; during operation, when the collection drawer 11 is placed into or removed from the placement rack 10, the anti-wear wheels 13 at the bottom of the collection drawer 11 can change the sliding friction between the collection drawer 11 and the placement rack 10 into rolling friction, thereby reducing the friction between the collection drawer 11 and the placement rack 10 and reducing wear between them.

[0034] like Figure 3 As shown, the bottom of the placement rack 10 is provided with a plurality of dust collection holes 101; the dust collection holes 101 are arranged in a linear array at the bottom of the placement rack 10; during operation, when coal dust particles fall into the interior of the placement rack 10, the dust collection holes 101 inside the placement rack 10 allow the coal dust particles inside the placement rack 10 to fall out of the placement rack 10, thereby making the interior of the placement rack 10 cleaner.

[0035] like Figure 2As shown, a plurality of balls 14 are provided between the rotating shaft 7 and the mounting cover 5; the sidewalls of the balls 14 are in contact with the sidewalls of the rotating shaft 7 and the mounting cover 5; during operation, as the rotating shaft 7 rotates, the rolling of the balls 14 can change the sliding friction between the rotating shaft 7 and the mounting cover 5 into rolling friction, thereby reducing the wear between the rotating shaft 7 and the mounting cover 5 and increasing the service life of the device.

[0036] like Figure 1 and Figure 7 As shown, a threaded rod 15 is fixedly connected to the bottom of the boiler pipe 3; a threaded sleeve 16 is threadedly connected to the external thread of the threaded rod 15; a connecting ball 18 is fixedly connected to the bottom of the threaded sleeve 16; a support block 17 is ball-connected to the end of the threaded sleeve 16 via the connecting ball 18; during operation, after the boiler body 1 is placed in the working position, the threaded sleeve 16 can be rotated, and the threaded engagement between the threaded sleeve 16 and the threaded rod 15 can be used to raise or lower the threaded rod 15, thereby adjusting the height of the threaded rod 15 and the threaded sleeve 16. This improves the support effect when supporting the boiler pipe 3. At the same time, by using the connecting ball 18 to ball-connect the support block 17 at the end of the threaded sleeve 16, the support block 17 can fit more closely to the placement position when the placement position deviates.

[0037] like Figure 8 As shown, a rubber pad 19 is fixed to the bottom of the support block 17; the shape and size of the rubber pad 19 are correspondingly set to the support block 17; during operation, when the support block 17 is placed at the placement position, by setting the rubber pad 19 at the bottom of the support block 17, the contact area between the support block 17 and the placement position can be larger, thereby increasing the friction between the support block 17 and the placement position, and thus improving the support effect of the support block 17.

[0038] During operation, as flue gas enters the boiler body 1 through boiler pipe 3, coal dust particles carried in the flue gas adhere to the side wall of boiler pipe 3. At this time, the drive component 6 can be activated, causing the drive component 6 to drive the rotating shaft 7 to rotate, which in turn causes the rotating shaft 7 to drive the knocking plate 8 to rotate. The vibration of the knocking plate 8 striking the side wall of boiler pipe 3 can shake off the coal dust particles on the side wall of boiler pipe 3, thereby making the inner side wall of boiler pipe 3 cleaner. This effectively avoids the situation where coal dust particles adhere to the inner side wall of boiler pipe 3, resulting in poor ventilation of boiler pipe 3. At the same time, the coal dust particles fall into the collection component for collection, making the cleaning of coal dust particles more convenient.

[0039] When the drive assembly 6 drives the rotating shaft 7 to rotate, causing the striking plate 8 to strike the side wall of the boiler pipe 3, the deflectable plate 9 is provided to reduce the likelihood of breakage during the impact of the striking plate 8 with the boiler pipe 3. At the same time, the arc-shaped striking plate 8 and the deflectable plate 9 reduce the shaking of the deflectable plate 9 when it strikes the surface of the boiler pipe 3, thus making the striking plate 8 and the deflectable plate 9 more effective in striking the boiler pipe 3.

[0040] When the side wall of the boiler pipe 3 is struck, the coal dust particles on the inner side wall of the boiler pipe 3 fall into the collection drawer 11. The coal dust particles can then be collected through the collection drawer 11. When it is necessary to clean the coal dust particles, the collection drawer 11 can be pulled out and the collected coal dust particles can be taken out, which makes the handling of coal dust particles more convenient.

[0041] When the collection tray 11 is placed inside the placement rack 10, the mutual attraction of the two fixed magnetic blocks 12 makes the collection tray 11 more stable inside the placement rack 10, thus making the collection tray 11 more effective at collecting coal powder particles.

[0042] When the collection drawer 11 is placed into or removed from the rack 10, the bottom of the collection drawer 11 is provided with anti-wear wheels 13, which can change the sliding friction between the collection drawer 11 and the rack 10 into rolling friction, making the friction between the collection drawer 11 and the rack 10 smaller, thereby reducing the wear between the collection drawer 11 and the rack 10.

[0043] When coal dust particles fall into the interior of the placement rack 10, the coal dust particles inside the placement rack 10 can fall out of the placement rack 10 by opening a dust collection hole 101 inside the placement rack 10, thereby making the interior of the placement rack 10 cleaner.

[0044] During the rotation of the rotating shaft 7, the rolling of the ball bearings 14 transforms the sliding friction between the rotating shaft 7 and the mounting cover 5 into rolling friction, thereby reducing wear between the rotating shaft 7 and the mounting cover 5 and increasing the service life of the device.

[0045] After the boiler body 1 is placed in the working position, the threaded sleeve 16 can be rotated, and the threaded sleeve 16 and the threaded rod 15 can be engaged to raise or lower the threaded rod 15. The height of the threaded rod 15 and the threaded sleeve 16 can be adjusted, so that the support effect of the boiler pipe 3 can be better. At the same time, by using the connecting ball 18 at the end of the threaded sleeve 16 to ball connect the support block 17, the support block 17 can be more closely matched to the placement position when the placement position is deflected.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
