Description

Technical Field

[0001] This utility model belongs to the field of coal powder silo cleaning, specifically, it relates to a wall cleaning device suitable for coal powder silos. Background Technology

[0002] A pulverized coal silo is a device for storing pulverized coal. After the raw coal is ground into powder, it is transferred to the silo for storage. Because the silo contains moisture, the pulverized coal combined with the moisture easily adheres to the inner wall of the silo. Over time, this leads to a thick layer of sticky material accumulating on the inner wall of the silo, which affects the actual storage capacity of the silo.

[0003] Chinese Patent Publication No. CN217806530U discloses a wall cleaning device suitable for pulverized coal silos, including a top seat mechanism, a pulling mechanism, a column, an anti-tipping mechanism, a CPU, a rotating mechanism, and a wall scraping mechanism. The top seat mechanism is located inside the pulverized coal silo; the pulling mechanism is located on the upper end face of the top seat mechanism, and the column is located on the lower end face of the top seat mechanism; both the anti-tipping mechanism and the rotating mechanism are located on the column, with the anti-tipping mechanism situated between the rotating mechanism and the top seat mechanism; the wall scraping mechanism is located on the rotating mechanism. This invention improves the cleaning efficiency of the inner wall of the pulverized coal silo and reduces the labor intensity of workers.

[0004] In practical use, the existing technology involves placing the entire component inside the coal powder silo, and then having personnel assemble the component inside the silo. This results in some coal powder from the air being absorbed by the personnel, which can affect their health. Furthermore, this process is time-consuming and labor-intensive. Therefore, a wall-cleaning device suitable for coal powder silos is needed.

[0005] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-5 As shown, this embodiment provides a wall cleaning device suitable for pulverized coal silos, including a first support frame 1, a hoisting mechanism 4 on the first support frame 1, a cleaning component on the lower side of the first support frame 1, and an adjustment component inside the first support frame 1.

[0027] The adjustment assembly includes a first fixed cylinder mounted on the first support frame 1, a first motor 15 mounted on the top of the inner wall of the first fixed cylinder, a first gear 16 rotatably engaged inside the first support frame 1, first sliding blocks 6 slidably engaged on opposite sides inside the first support frame 1, a first toothed plate 14 mounted on one side of the first sliding block 6, one side of the first gear 16 fixedly connected to the output end of the first motor 15, a fixed disk 3 mounted on the first fixed cylinder, a winch 4 mounted on the fixed disk 3, the first gear 16 being located between and meshing with the two first toothed plates 14, and a moving component being provided inside the first sliding block 6.

[0028] One application of this embodiment is as follows: The hoisting mechanism is installed on the first support frame 1, and its function is to hoist the entire device to a suitable position inside the coal powder silo. The winch 4 installed on the fixed plate 3 can vertically lift or horizontally pull external equipment or components through steel wire ropes, which is suitable for scenarios requiring high-altitude operations or heavy object handling. When it is necessary to clean the coal powder silo, the hoisting mechanism is started, and the device is smoothly placed into the coal powder silo. By turning on the first motor 15, its output end drives the first gear 16 fixedly connected to it to rotate. Since the first gear 16 is located between two first toothed plates 14 and meshes with each other, the rotation of the first gear 16 will cause the meshing first toothed plates 14 to move. The first toothed plates 14 are installed on one side of the first sliding block 6, which drives the first sliding block 6 on the first support frame 1 to move. The frame 1 slides on both sides inside. By controlling the forward and reverse rotation of the first motor 15, the first sliding block 6 can be moved back and forth, which facilitates the adjustment according to the size of different coal powder bins. This avoids the need for personnel to enter the coal powder bin to assemble the whole device. The winch 4 can further adjust the height or position of the device through ropes or other means to ensure that the cleaning component can reach the position that needs to be cleaned in the coal powder bin. The cleaning component is installed on the lower side of the first support frame 1. With the cooperation of the adjustment component and the moving component, the cleaning component can reach different positions on the coal powder bin wall to clean the coal powder adhering to the bin wall.

[0029] The moving component of this embodiment includes a placement groove formed inside the first sliding block 6. A second motor 7 is installed on one side of the inner wall of the placement groove. A first through groove 13 is formed on opposite sides of the inner wall of the placement groove. A rotating rod 9 is rotatably engaged inside the first through groove 13. A worm gear 8 is installed at the output end of the second motor 7. A worm wheel 10 is installed on the rotating rod 9. The worm gear 8 and the worm wheel 10 mesh with each other. Anti-slip rollers 11 are provided on both sides of the first sliding block 6. One side of the anti-slip roller 11 is fixedly connected to one end of the rotating rod 9.

[0030] By activating the second motor 7, its output power drives the worm gear 8 connected to it to rotate. The second motor 7, as the power source of the moving component, provides the initial driving force for the entire movement process. Its rotation causes the worm wheel 10, which is mounted on the rotating rod 9, to also rotate. The rotation of the worm wheel 10 drives the rotating rod 9 to rotate as well. The first through groove 13 is opened on opposite sides of the inner wall of the placement groove, providing space and support for the rotation of the rotating rod 9. One end of the rotating rod 9 is fixedly connected to the anti-slip roller 11. When the rotating rod 9 rotates, it drives the anti-slip roller 11 to rotate. The anti-slip roller 11 is located on both sides of the first sliding block 6. When the anti-slip roller 11 rotates, it generates friction with the inner wall of the coal powder bin. Under the action of this friction, the first sliding block 6 will move along the inner wall of the coal powder bin, making it easier to reach different positions on the coal powder bin wall more flexibly, thereby better cleaning the coal powder bin wall.

[0031] In this embodiment, a second fixed cylinder 2 is installed on the lower side of the first support frame 1. A third motor 19 is installed on the top of the inner wall of the second fixed cylinder 2. A fixed plate 20 is installed at the output end of the third motor 19. A limit groove 17 is formed on the inner wall of the second fixed cylinder 2. A limit plate is installed on the fixed plate 20 and rotates and engages inside the limit groove 17. The cleaning component includes a protective shell 23 installed on the lower side of the fixed plate 20. A second support frame 22 is installed on the lower side of the protective shell 23. A fourth motor 24 is installed on the top of the inner wall of the protective shell 23. Second sliding blocks are slidably engaged with each other on opposite sides inside the second support frame 22. 27; A second toothed plate 26 is installed on one side of the second sliding block 27, and a second gear 25 is rotatably engaged inside the second support frame 22. The second gear 25 is fixedly connected to the output end of the fourth motor 24. The second gear 25 is located between and meshes with the two second gears 25. A plurality of scrapers 28 are installed on one side of the second sliding block 27; An annular frame 21 is installed on the upper side of the second support frame 22, and a limiting rod 18 is installed on the lower side of the fixed disk 3. One end of the limiting rod 18 is rotatably engaged with a guide disk; A T-shaped annular groove is opened on one side of the annular frame 21, and the guide disk is slidably engaged inside the T-shaped annular groove.

[0032] By activating the fourth motor 24, its output drives the second gear 25, which is fixedly connected to it, to rotate. The rotation of the second gear 25 causes the second toothed plate 26, which meshes with it, to move. This causes the second sliding block 27 to slide linearly inside the second support frame 22. Multiple scrapers 28 installed on one side of the second sliding block 27 move with the sliding of the second sliding block 27. The scrapers 28 contact the coal powder bin wall. Then, by activating the third motor 19, its output drives the fixed disk 20 to rotate. The fixed disk 20 is equipped with a limit plate, which rotates in conjunction with the limit plate opened on the inner wall of the second fixed cylinder 2. Inside the positioning groove 17, the cooperation between the positioning groove 17 and the positioning plate restricts the rotation trajectory of the fixed plate 20, ensuring that the fixed plate 20 can rotate stably and smoothly, thereby avoiding shaking or deviation. At the same time, the two second sliding blocks 27 inside the second support frame 22 rotate with the rotation of the protective shell 23, so that the scraper 28 cleans the inner wall of the coal powder bin, thereby scraping and cleaning the coal powder on the bin wall. During the cleaning process, the adjusting component and the moving component can adjust the overall position and posture of the device as needed to ensure that the scraper 28 can clean the coal powder bin wall comprehensively and effectively.
