[0001] This utility model relates to the technical field of angle iron marking equipment, and in particular to a metallurgical flue gas cleaning device. Background Technology

[0002] In the metallurgical industry, flue gas pipes are crucial channels for ensuring the emission and purification of waste gas. As smelting operations continue, the inner walls of these pipes gradually accumulate a large amount of ash, tar, sintered materials, and other contaminants. This contamination not only reduces the cross-sectional area of ​​the flue gas pipe, increasing flow resistance and reducing exhaust efficiency, but also affects subsequent waste gas purification and treatment. In severe cases, excessive buildup can even cause pipe blockages, threatening production safety.

[0003] Currently, metallurgical enterprises mainly rely on manual or simple mechanical cleaning methods to clean flue gas pipes. When cleaning manually, operators need to wear protective equipment to enter the narrow flue gas pipe and use tools such as scrapers and brushes to clean it. This is not only labor-intensive and inefficient, but also exposes operators to safety risks such as poisoning, suffocation, and burns in harsh environments with high temperatures, dust, and harmful gases.

[0019] In the description of this utility model, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0021] To address the problems existing in the background technology, this application proposes the following technical solution: a metallurgical flue gas pipe cleaning device, including a mounting column 1, a fixing column 5 fixedly connected to the mounting column 1, a collection tray 2 fixedly connected to the outside of the fixing column 5, the collection tray 2 having a cylindrical structure, a motor 6 fixedly connected to the top of the fixing column 5, multiple sets of first scrapers 7 fixedly connected to the output end of the motor 6, and a second scraper 8 fixedly connected to one end of the first scraper 7. A traveling assembly is also provided on the outside of the fixing column 5. After long-term use, a large amount of ash, tar, and other dirt will accumulate on the inner wall of the flue gas pipe. The mounting column 1, as a basic support structure, provides a stable carrier for the entire device. The fixing column 5 connects the mounting column 1 and the collection tray 2, ensuring the stable installation of the collection tray 2. The cylindrical collection tray 2 can effectively receive the scraped dirt; compared to other shapes, its circular structure makes the dirt less likely to spill, facilitating centralized cleaning. The motor 6 at the top of the fixing column 5 is the core component driving the scraper rotation; the multiple sets of first scrapers 7 and second scrapers 8 cooperate to form a three-dimensional scraping structure. The second scraper 8 can clean deeper, greatly improving the thoroughness of the cleaning. The walking component allows the device to move autonomously inside the flue gas pipe, changing the dangerous mode of traditional manual pipe cleaning. This not only improves cleaning efficiency but also ensures the safety of operators. It can adapt to the cleaning needs of flue gas pipes of different lengths and diameters, significantly reducing the cost and difficulty of flue gas pipe cleaning in metallurgical enterprises.

[0022] In this embodiment, a spring plate 3 is fixedly connected to the outside of the collection tray 2, and a scraper ring 4 is fixedly connected to the outside of the spring plate 3. The scraper ring 4 is made of rubber, and an iron ring is fixedly connected to the edge of the scraper ring 4. The rubber scraper ring 4 is elastic, while the iron ring can assist in scraping. The added spring plate 3 and scraper ring 4 structure on the outside of the collection tray 2 further optimizes the cleaning effect. The spring plate 3 has good elastic deformation capability and can automatically adjust the fit of the scraper ring 4 according to the shape of the inner wall of the flue. The rubber scraper ring 4 is soft and elastic, and under the action of the spring plate 3, it can fit tightly against the inner wall of the flue, avoiding cleaning dead corners due to unevenness of the inner wall of the pipe. At the same time, the elasticity of the rubber can also reduce the hard friction between the scraper ring 4 and the inner wall of the pipe, preventing damage to the flue and extending the service life of the pipe. The iron ring on the edge of the scraper ring 4 enhances the scraping force. For some stubborn dirt, the iron ring can provide stronger scraping force to effectively remove it. During the cleaning process, as the device moves, the scraper ring 4 continuously wipes and scrapes the inner wall of the flue pipe, further cleaning up the dirt missed or not completely removed by the scraper and pushing it into the collection tray 2. This forms a double cleaning guarantee with the scraper, greatly improving the quality and effect of the cleaning, ensuring that the inner wall of the flue pipe can be cleaned more thoroughly, effectively improving the ventilation performance and operational safety of the flue pipe, and reducing the risk of failure caused by dirt accumulation.

[0023] In this embodiment, the walking assembly includes multiple sets of adjusting frames 15 disposed outside the mounting column 1 and rollers 16 rotatably connected to both ends of the adjusting frames 15. The rollers 16 have anti-slip textures on their outer surfaces. A drive motor 14 is fixedly connected to the outer surface of each adjusting frame 15, and the output end of the drive motor 14 is fixedly connected to the rollers 16. The multiple sets of adjusting frames 15 are arranged around the mounting column 1, providing a basic structure for the installation and adjustment of the rollers 16. The rollers 16 at both ends of the adjusting frames 15 are driven to rotate by the drive motor 14, thereby driving the device to move within the flue gas pipe. The anti-slip texture design on the outer surface of the rollers 16 is crucial; it effectively increases the friction between the rollers 16 and the inner wall of the flue gas pipe, preventing slippage during movement and ensuring smooth movement within the flue gas pipe. The drive motor 14, as a power source, provides stable and continuous power output to the rollers 16, and can flexibly adjust the travel speed according to the length of the flue gas pipe, the condition of the dirt, and other actual conditions. During the cleaning process, the mobile component allows the device to penetrate deep into various areas inside the flue pipe for cleaning, eliminating the need for manual dragging or carrying and greatly reducing the labor intensity of operators. At the same time, its autonomous movement improves cleaning efficiency, enabling the device to clean the flue pipe quickly and thoroughly, significantly shortening the cleaning time compared to traditional manual cleaning methods.

[0024] In this embodiment, multiple sets of connecting rods 9 are provided between the adjusting frame 15 and the mounting column 1. The connecting rods 9 are hinged to each other, forming a scissor-like structure. The connecting rods 9 are hinged to the adjusting frame 15 and the mounting column 1. A hinge seat 13 is fixedly connected to the outside of the mounting column 1. The connecting rods 9 are rotatably connected to the hinge seat 13. Guide rails 11 are fixedly connected to the outside of both the adjusting frame 15 and the mounting column 1. A slider 12 is slidably connected in the guide rail 11. The connecting rods 9 are hinged to the slider 12. A cylinder 10 is fixedly connected to the outside of the mounting column 1. The output end of the cylinder 10 is fixedly connected to the slider 12. The adjusting mechanism consisting of the connecting rods 9, guide rails 11, slider 12, and cylinder 10 between the adjusting frame 15 and the mounting column 1 gives the device the ability to adapt to flue gas pipes of different diameters. The scissor-like connecting rod 9 structure utilizes the lever principle. The cylinder 10 pushes the slider 12 to slide on the guide rail 11, realizing the extension and retraction of the adjusting frame 15. When cylinder 10 extends and pushes slider 12 to slide, connecting rod 9 unfolds, causing adjusting frame 15 to expand outward, allowing roller 16 to press firmly against the inner wall of the flue pipe. When cylinder 10 retracts, connecting rod 9 retracts, and adjusting frame 15 moves inward, facilitating the device's entry and exit from the flue pipe or adapting to pipes with smaller diameters. The advantage of this design is that one device can be used for cleaning flue pipes of various diameters, greatly improving the device's versatility and applicability.

[0025] The usage method of this embodiment is as follows:

[0026] Place the device inside the pipe that needs cleaning, and start the cylinder 10, drive motor 14, and motor 6. The cylinder 10 pushes the slider 12 to slide, and the slider 12 drives the connecting rod 9 to move. The connecting rod 9 pushes the adjusting frame 15 to move outward until the roller 16 touches the inner wall of the pipe. The drive motor 14 drives the roller 16 to rotate, thereby moving the device inside the pipe. The motor 6 drives the first scraper 7 and the second scraper 8 to rotate, thereby scraping the dirt in the pipe onto the collection tray 2 for collection. After cleaning, remove the device and clean the dirt from the collection tray 2.
