Description

Technical Field

[0001] This invention relates to the field of ash hopper cleaning technology, specifically to an ash hopper cleaning device that uses a grid to refine ash blocks. Background Technology

[0002] The ash hopper is a crucial component of dust collection equipment. Factors contributing to ash buildup on the hopper walls include the ash's moisture content, particle size variations, temperature changes, storage time, and the coefficient of friction of the hopper's inner wall. When the ash material in the hopper is highly viscous, it adheres to the inner wall, eventually forming ash deposits that are difficult to remove. Excessive ash accumulation or obstructed ash discharge necessitates shutdown for maintenance. This requires disassembling and relocating the ash discharge valve, followed by unclogging with tools – a highly demanding task.

[0003] In the prior art, Chinese Patent No. CN222326117U discloses a multifunctional ash hopper cleaning device. By rotating the connecting rods on both sides of the drive shaft, as well as the guide rod and sliding sleeve, two positioning plates and two cleaning plates can be pressed against the inner walls of ash hoppers of different sizes, thereby improving the applicability of the ash hopper cleaning device. Through the snap-fit ​​plate set at one end of the two cleaning plates, and in conjunction with the snap-fit ​​groove opened on one side of the two positioning plates, the cleaning plates can be easily installed or removed, thereby allowing the cleaning plates to be replaced. This enables the cleaning plates to better clean the ash accumulated on the inner wall of the ash hopper, solving the problem that the cleaning plates in existing cleaning devices cannot be used for ash hoppers of different sizes.

[0004] As described above, the linkage rod, guide rod, and sliding sleeve are used to make the cleaning plate suitable for ash hoppers of different sizes. However, in this scheme, the cleaning plate is only used to clean the inner wall of the ash hopper. Due to the single friction force and cleaning method of the cleaning plate, it is not possible to effectively break the adhesion between the ash block and the inner wall of the ash hopper. This makes it difficult for some ash to be completely removed, affecting the cleaning effect. Furthermore, the long-term friction between the cleaning plate and the inner wall of the ash hopper can easily lead to wear of the cleaning plate, reduce its service life, and may cause a certain degree of damage to the inner wall of the ash hopper. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a ash hopper cleaning device with a finer grating, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0012] Preferably, a T-shaped shaft is fixedly installed on the lower end face of the driven gear, a drive rod is rotatably installed on the T-shaped shaft, a pull rod is rotatably installed on the end of the drive rod away from the driven gear, a push rod is fixedly installed on the end of the pull rod away from the drive rod, and a limit block is fixedly installed on the upper end face of the ash hopper body.

[0013] Preferably, the rinsing assembly includes a sliding groove formed on the cross plate, a sliding block slidably installed inside the sliding groove, a limit baffle fixedly installed on the upper end face of the sliding block, an arc-shaped square tube fixedly installed on the lower end face of the sliding block, a connecting rod fixedly installed on the lower end face of the arc-shaped square tube, and a connecting pipe fixedly connected to the upper end face of the arc-shaped square tube.

[0014] Preferably, the pull rod is slidably mounted on the limiting block, the end of the connecting rod away from the arc-shaped square tube is fixedly mounted on the pull rod, the end of the connecting tube away from the arc-shaped square tube passes through the sliding block and the limiting baffle in sequence, and is located above the cross plate, and the flushing head is fixedly connected to the arc-shaped square tube.

[0015] Preferably, the striking assembly includes a rotating shaft rotatably mounted on an L-shaped frame plate, with push plates fixedly mounted at both ends of the rotating shaft. The inner side of the push plate is provided with a push groove, and a driven rod is rotatably mounted on the rotating shaft. The end of the driven rod is provided with a tooth block assembly.

[0016] Preferably, a positioning frame plate is fixedly installed on the outer side of the push plate, a first electric push rod is fixedly installed on the positioning frame plate, and a toothed plate is fixedly installed on the output rod of the first electric push rod. The driven rod is positioned on the rotating shaft by the meshing of the toothed plate with the toothed block assembly. A rotating groove is provided on the L-shaped frame plate.

[0017] Preferably, a second electric push rod is fixedly installed inside the driven rod, an extension rod is fixedly installed at the output end of the second electric push rod, and the striking head is fixedly installed at the tail end of the extension rod.

[0018] Preferably, both ends of the push rod are located in the push grooves on the two push plates. The push rod is slidably installed with the push grooves. Through the cooperation of the toothed plate and the toothed block assembly, and the adjustment of the position of the striking head by the extension rod, the striking head can strike different positions of the ash hopper body.

[0019] This invention provides a dust hopper cleaning device that refines dust particles using a grid. Compared with the prior art, it has the following advantages:

[0020] 1. This invention uses a drive motor to rotate the output shaft. A crossbar on the output shaft drives a cleaning rod to slide against the inner wall of the ash hopper body. The cleaning rod facilitates the cleaning of ash clumps on the inner wall of the ash hopper body. Simultaneously, when the output shaft rotates, it drives the drive gear to rotate. The meshing of the drive gear and the driven gear, through the cooperation of the bearing and the drive shaft, drives the drive rod on the T-shaped shaft to rotate around the drive shaft. The cooperation of the drive rod and the pull rod, as well as the cooperation of the pull rod and the limiting block, causes the pull rod to adjust the position of the arc-shaped square tube on the connecting rod. The arc-shaped square tube, through the cooperation of the sliding block and the sliding groove, and the positioning of the limiting baffle, allows the flushing head on the arc-shaped square tube to be adjusted horizontally. This facilitates the flushing head to spray cleaning water evenly onto the inner wall of the ash hopper body, effectively improving the cleaning effect of the ash hopper body.

[0021] 2. In this invention, when the pulling rod drives the pushing rod to move horizontally back and forth, the pushing rod cooperates with the pushing groove on the pushing plate, so that the pushing plate rotates back and forth around the rotation axis. Then, through the cooperation of the toothed plate with the toothed block group on the driven rod, the striking head on the driven rod repeatedly strikes the surface of the ash hopper body. The striking force generated by the striking head makes it easy for the ash blocks on the inner wall of the ash hopper body to fall off.

[0022] 3. In this invention, when it is necessary to tap different positions of the ash hopper body, the first electric push rod drives the toothed plate to move inward, the driven rod will rotate around the rotation axis, and the angle between the driven rod and the push plate will increase. At the same time, the second electric push rod drives the extension rod to adjust the position of the tapping head, so that the tapping head always fits against the outer wall of the ash hopper body when adjusting the position. After the tapping head is adjusted, the push rod cooperates with the push groove on the push plate, so that the tapping head can tap the ash hopper body, effectively improving the use effect of the ash hopper cleaning device.

[0023] 4. This invention, through the coordinated use of the driving component, linkage component, flushing component and tapping component, utilizes the synergistic work of different components to achieve the cleaning and tapping functions of the inner wall of the ash hopper, ensuring the comprehensive cleaning of the inner wall of the ash hopper, ensuring that ash blocks are effectively removed, and greatly improving the use effect of the ash hopper cleaning device.

The bottom end of the ash hopper body 1 is provided with a discharge gate; since this discharge gate is a technology well known to those skilled in the art, it will not be described in detail here.

[0035] The drive assembly includes a drive motor 7 fixedly mounted on the cross plate 3. An output shaft 8 is fixedly mounted on the output end of the drive motor 7. A crossbar 9 is fixedly mounted on the output shaft 8. A cleaning rod 4 is fixedly mounted on the crossbar 9. The linkage assembly includes a drive gear 10 fixedly mounted on the output shaft 8 and a mounting column 11 fixedly mounted on the cross plate 3. A bearing 12 is fixedly mounted on the bottom end of the mounting column 11. A drive shaft 13 is fixedly mounted on the bearing 12. A driven gear 14 is fixedly mounted on the drive shaft 13. The drive gear 10 meshes with the driven gear 14. A T-shaped shaft 15 is fixedly mounted on the lower end face of the driven gear 14. A drive rod 16 is rotatably mounted on the T-shaped shaft 15. A pull rod 17 is rotatably mounted on the end of the drive rod 16 away from the driven gear 14. A push rod 18 is fixedly mounted on the end of the pull rod 17 away from the drive rod 16. A limit block 19 is fixedly mounted on the upper end face of the ash hopper body 1. The flushing assembly includes a sliding groove 20 formed on the cross plate 3. A sliding block 21 is slidably mounted inside the sliding groove 20. A limit baffle 22 is fixedly installed on the upper end face of the sliding block 21, and an arc-shaped square tube 23 is fixedly installed on the lower end face of the sliding block 21. A connecting rod 24 is fixedly installed on the lower end face of the arc-shaped square tube 23, and a connecting pipe 25 is fixedly connected to the upper end face of the arc-shaped square tube 23. A pulling rod 17 is slidably installed on the limit block 19. The end of the connecting rod 24 away from the arc-shaped square tube 23 is fixedly installed on the pulling rod 17. The end of the connecting pipe 25 away from the arc-shaped square tube 23 passes through the sliding block 21 and the limit baffle 22 in sequence, and is in a ten-degree position. Above the frame plate 3, the flushing head 5 is fixedly connected to the arc-shaped square tube 23. The connecting pipe 25 can be connected to the external hose, which in turn is connected to the water supply pipe. Since this technology is well known to those skilled in the art, it will not be described in detail here. The pull rod 17 is square in shape, and the limiting block 19 is provided with a square opening. The pull rod 17 is slidably installed with the limiting block 19 through the square opening, and the pull rod 17 will not shift its position when it slides on the limiting block 19.

[0036] In this embodiment, the drive motor 7 drives the output shaft 8 to rotate. The crossbar 9 on the output shaft 8 drives the cleaning rod 4 to slide against the inner wall of the ash hopper body 1. The cleaning rod 4 facilitates the cleaning of ash clumps on the inner wall of the ash hopper body 1. At the same time, when the output shaft 8 rotates, it drives the drive gear 10 to rotate. The drive gear 10 meshes with the driven gear 14. The driven gear 14, through the bearing 12 and the engagement with the drive shaft 13, drives the drive rod 16 on the T-shaped shaft 15 to rotate around the drive shaft 13. By utilizing the cooperation between the drive rod 16 and the pull rod 17, and the cooperation between the pull rod 17 and the limiting block 19, the pull rod 17 drives the arc-shaped square tube 23 on the connecting rod 24 to adjust its position. The arc-shaped square tube 23 is then positioned by the cooperation between the sliding block 21 and the sliding groove 20, and the positioning of the limiting baffle 22, so that the flushing head 5 on the arc-shaped square tube 23 can be adjusted horizontally. This makes it easier for the flushing head 5 to spray the cleaning water evenly on the inner wall of the ash hopper body 1, effectively improving the cleaning effect of the ash hopper body 1.

[0037] The striking assembly includes a rotating shaft 26 rotatably mounted on an L-shaped frame plate 2. Push plates 27 are fixedly mounted at both ends of the rotating shaft 26. Push grooves 28 are formed on the inner side of the push plates 27. A driven rod 29 is rotatably mounted on the rotating shaft 26. A toothed block assembly 30 is provided at the end of the driven rod 29. A positioning frame plate 31 is fixedly mounted on the outer side of the push plates 27. A first electric push rod 32 is fixedly mounted on the positioning frame plate 31. A toothed plate 33 is fixedly mounted on the output rod of the first electric push rod 32. The toothed plate 33 meshes with the toothed block assembly 30, positioning the driven rod 29 on the rotating shaft 26. A rotating groove 34 is formed on the L-shaped frame plate 2. A second electric push rod 35 is fixedly mounted inside the driven rod 29. An extension rod 36 is fixedly mounted on the output end of the second electric push rod 35. The striking assembly... The head 6 is fixedly installed at the tail end of the extension rod 36. The two ends of the push rod 18 are located in the push grooves 28 on the two push plates 27. The push rod 18 is slidably installed with the push grooves 28. Through the cooperation of the toothed plate 33 and the toothed block group 30, and the adjustment of the position of the striking head 6 by the extension rod 36, the striking head 6 can strike different positions of the ash hopper body 1. The cooperation of the toothed plate 33 and the toothed block can ensure that the driven rod 29 will not change position on the rotating shaft 26. Through the horizontal movement of the push rod 18, the push plate 27 will rotate around the rotating shaft 26 through the cooperation with the push rod 18. The end of the extension rod 36 away from the second electric push rod 35 extends to the outside of the driven rod 29, and the extension rod 36 is slidably installed with the driven rod 29.

[0038] In this embodiment, when the pulling rod 17 drives the pushing rod 18 to move horizontally back and forth, the pushing rod 18 cooperates with the pushing groove 28 on the pushing plate 27, causing the pushing plate 27 to rotate back and forth around the rotating shaft 26. Then, through the cooperation of the toothed plate 33 and the toothed block group 30 on the driven rod 29, the striking head 6 on the driven rod 29 reciprocates to strike the surface of the ash hopper body 1. The striking force generated by the striking head 6 facilitates the removal of ash blocks from the inner wall of the ash hopper body 1. When it is necessary to strike different positions of the ash hopper body 1, the first... The electric push rod 32 drives the toothed plate 33 to move inward, and the driven rod 29 rotates around the rotating shaft 26. The angle between the driven rod 29 and the push plate 27 increases. At the same time, the second electric push rod 35 drives the extension rod 36 to adjust the position of the striking head 6, so that the striking head 6 always fits against the outer wall of the ash hopper body 1 when adjusting the position. After the striking head 6 is adjusted, the push rod 18 cooperates with the push groove 28 on the push plate 27, so that the striking head 6 can strike the ash hopper body 1, effectively improving the use effect of the ash hopper cleaning device.

[0039] Working principle: During operation, the drive motor 7 drives the output shaft 8 to rotate. The crossbar 9 on the output shaft 8 drives the cleaning rod 4 to slide against the inner wall of the ash hopper body 1, facilitating the cleaning of ash clumps on the inner wall of the ash hopper body 1. Simultaneously, the rotation of the output shaft 8 drives the drive gear 10 to rotate. The meshing of the drive gear 10 and the driven gear 14, along with the engagement of the driven gear 14 with the drive shaft 13 via the bearing 12, drives the drive rod 16 on the T-shaped shaft 15 to rotate around the drive shaft 13. Rotation, combined with the engagement of drive rod 16 and pull rod 17, and pull rod 17 and limit block 19, causes pull rod 17 to move the arc-shaped square tube 23 on connecting rod 24 to adjust its position. The arc-shaped square tube 23, through the engagement of sliding block 21 and sliding groove 20, and the positioning by limit baffle 22, allows the flushing head 5 on the arc-shaped square tube 23 to be adjusted horizontally, facilitating the even spraying of cleaning water onto the inner wall of the ash hopper body 1. When pull rod 17 drives push rod 18... During the horizontal reciprocating movement, the push rod 18 engages with the push groove 28 on the push plate 27, causing the push plate 27 to reciprocate around the rotation shaft 26. Then, the toothed plate 33 engages with the toothed block assembly 30 on the driven rod 29, causing the striking head 6 on the driven rod 29 to reciprocate and strike the surface of the ash hopper body 1. The striking force generated by the striking head 6 facilitates the removal of ash blocks from the inner wall of the ash hopper body 1. When different positions of the ash hopper body 1 need to be struck, the first electric push rod 32 drives the toothed plate 30 to reciprocate. When plate 33 moves inward, driven rod 29 rotates around rotating shaft 26, increasing the angle between driven rod 29 and push plate 27. Simultaneously, the second electric push rod 35 drives extension rod 36 to adjust the position of striking head 6, ensuring that striking head 6 always fits against the outer wall of ash hopper body 1 during adjustment. After striking head 6 is adjusted, push rod 18 engages with push groove 28 on push plate 27, allowing striking head 6 to strike ash hopper body 1, effectively improving the performance of the ash hopper cleaning device.
