[0035] Reference Figures 1-5 A beam type cleaning mechanism for a mixer is provided for cleaning the inner wall of a rotary kiln 1, characterized in that it comprises: a crossbeam 2, which is erected outside the rotary kiln 1 and extends into the rotary kiln 1; a frame 3, which is movably arranged on the crossbeam 2 and moves into or out of the rotary kiln 1; a scraper 4, which is arranged on the frame 3 and is used for cleaning the inner wall of the rotary kiln 1; the scraper 4 has a fixed part 401, a scraping part 402 and a handle part 403, the scraping part 402 and the fixed part 401 have an included angle, and the handle part 403 and the fixed part 401 also have an included angle.

[0036] In this embodiment, the crossbeam 2 is erected outside the rotary kiln 1 and extends into the rotary kiln 1. As shown in the figures, the volume of the crossbeam 2 is reduced for clarity to show the relationship between the frame 3 and the crossbeam 2. It serves as the supporting structure of the entire cleaning system, ensuring the stable installation and operation of other components. The frame 3 is movably arranged on the crossbeam 2 and can slide back and forth on the crossbeam 2. Through the driving device, the frame 3 can flexibly enter or move out of the rotary kiln 1. When cleaning is needed, the frame 3 enters the interior of the rotary kiln 1; after cleaning is completed, the frame 3 moves out of the rotary kiln 1, facilitating maintenance and inspection. The scraper 4 is arranged on the frame 3 and directly contacts and acts on the inner wall of the rotary kiln 1. The main function of the scraper 4 is to clean the residues such as the skin and accumulated material on the inner wall of the rotary kiln 1. Through the movable arrangement of the frame 3 and the automatic cleaning function of the scraper 4, the automation of the inner wall cleaning of the rotary kiln 1 is realized, greatly improving the cleaning efficiency and reducing the downtime. Since the frame 3 can slide back and forth on the crossbeam 2, and the rotary kiln 1 rotates synchronously, the scraper 4 performs spiral cleaning on the inner wall of the rotary kiln 1, ensuring that the entire inner wall of the rotary kiln 1 can be effectively cleaned, avoiding the areas that may be missed during manual cleaning. The cleaning process is completely completed by the equipment, without the need for workers to enter the dangerous environment of high temperature and high dust, significantly reducing the probability of safety accidents. Timely cleaning of the skin and accumulated material on the inner wall reduces equipment damage caused by uneven heat transfer, prolonging the service life of the rotary kiln 1.

[0037] Further, the handle part 403 and the scraping part 402 are both curved towards the same side of the fixed part 401.

[0038] In this embodiment, the double-angle design and curved shape of the scraper 4 enable it to better fit the different curvatures of the kiln wall, ensuring comprehensive coverage during cleaning and improving the cleaning effect.

[0039] Further, the angle between the scraping part 402 and the fixed part 401 is greater than the angle between the handle part 403 and the fixed part 401.

[0040] In this embodiment, the angle between the scraping part 402 and the fixed part 401 is greater than the angle between the handle part 403 and the fixed part 401, enabling the scraping part 402 to contact the inner wall of the rotary kiln 1 at a larger inclination angle during cleaning, while the handle part 403 provides support and flexibility at a smaller angle. The larger angle enables the scraping part 402 to better fit the curvature of the kiln wall, ensuring that it can penetrate into the gaps of the skin and accumulated material during cleaning, achieving more thorough scraping. The smaller angle enables the handle part 403 to provide necessary support and stability without affecting the work of the scraping part 402, while reducing direct impact on the kiln wall and reducing the risk of damage.

[0041] Further, the scraper 4 has two, two of the scraper 4 staggered front and back and staggered left and right along the moving direction of the frame body 3.

[0042] In this embodiment, the front and back and left and right staggered arrangement enables the two scrapers 4 to cover more surface area, reduces the cleaning dead angle, and ensures comprehensive cleaning of the inner wall of the rotary kiln 1. The front scraper 4 performs preliminary cleaning, and the rear scraper 4 performs fine cleaning, ensuring that each part can be thoroughly scraped off, improving the cleaning effect. The staggered arrangement of the scraper 4 enables larger area cleaning in one movement, reducing the need for repeated cleaning and significantly improving the cleaning efficiency. The staggered design enables the cleaning system to better adapt to complex kiln wall curvature and different thickness of the skin, enhancing the adaptability and reliability of the system.

[0043] Further, the upper part of the scraping part 402 is used to clean the inside of the rotary kiln 1. The part of the scraping part 402 located at the upper part of the scraping part 402 and close to the fixed part 401 is the first end part 404, and the part of the scraping part 402 located at the upper part of the scraping part 402 and away from the fixed part 401 is the second end part 405. The first end part 404 of one of the scrapers 4 and the second end part 405 of the other scraper 4 are located on the same horizontal line perpendicular to the moving direction of the frame body 3.

[0044] In this embodiment, the rear scraper 4 is next to the front scraper 4, so that the two scrapers 4 are continuous in the direction of travel, forming a complete scraping surface, as shown in Figure 4 This design significantly improves the scraping effect, ensuring that the skin and accumulated material on the inner wall of the rotary kiln 1 are thoroughly removed, reducing the cleaning dead angle. The close arrangement of the two scrapers 4 ensures that the scraper 4 can cover more surface area during each movement, improving the cleaning efficiency and reducing the need for repeated cleaning, saving time and resources. Through the close arrangement of the scraper 4, even small residues can be effectively scraped off, reducing the problem of uneven heat transfer caused by residues, thereby improving product quality and equipment operation stability. The close cooperation of the two scrapers 4 simplifies the cleaning operation, reduces the time for adjustment and calibration, and makes the cleaning process smoother and more efficient.

[0045] Further, it also includes a rod seat 7 provided on the frame body 3, and an adjusting rod 8 provided on the rod seat 7 in a lifting manner. The scraper 4 is provided on the adjusting rod 8, which is provided on the frame body 3 through the adjusting rod 8.

[0046] In this embodiment, the rod seat 7 is provided on the frame body 3, providing a stable mounting platform. The adjusting rod 8 is arranged on the rod seat 7, allowing the height to be adjusted as needed. By adjusting the height of the adjusting rod 8, the distance between the scraper 4 and the inner wall of the rotary kiln 1 can be flexibly changed, ensuring that the scraper 4 is always in the best working position, and adapting to different thicknesses of the skin and accumulated material.

[0047] Further, the angle piece 5 is arranged on the frame body 3 and located in the moving direction of the frame body 3. The angle piece 5 has an angle part 501 facing away from the frame body 3, with the bottom close to the surface of the cross beam 2.

[0048] In this embodiment, the angle part 501 of the angle piece 5 is specially used to clean the dust, slag and other impurities accumulated on the upper surface of the cross beam 2. When the frame body 3 moves along the cross beam 2, the angle part 501 of the angle piece 5 is used to scrape off the accumulated material on the surface of the cross beam 2, ensuring that the frame body 3 can move smoothly and avoid being blocked by the accumulated impurities. With the movement of the frame body 3, the angle piece 5 also moves synchronously, continuously cleaning the dust and other impurities in front that may hinder the movement of the frame body 3. This dynamic cleaning method ensures that the angle part 501 can always clean the surface of the cross beam 2 whether the frame body 3 is moving forward or backward, reducing the risk of jamming or failure caused by accumulated material.

[0049] Through the movement of the frame body 3 and the automatic cleaning function of the scraper 4, the automation of the inner wall cleaning of the rotary kiln 1 is realized, greatly improving the cleaning efficiency and reducing the downtime. Since the frame body 3 can slide back and forth on the cross beam 2, combined with the synchronous rotation of the rotary kiln 1, the scraper 4 performs spiral cleaning on the inner wall of the rotary kiln 1, ensuring that the entire inner wall of the rotary kiln 1 can be effectively cleaned, avoiding the areas that may be missed during manual cleaning. The cleaning process is completely completed by the equipment, without the need for workers to enter the dangerous environment of high temperature and high dust, significantly reducing the probability of safety accidents. Timely cleaning of the skin and accumulated material on the inner wall reduces the damage caused by uneven heat transfer, prolonging the service life of the rotary kiln 1.

[0050] Further, the frame body 3 reciprocatingly moves on the cross beam 2, and the angle piece 5 has two, located on both sides of the frame body 3. The angle piece 5 has an inclined surface 502 located on the upper part of the angle piece 5, gradually decreasing in height from close to the frame body 3 to away from the frame body 3.

[0051] In this embodiment, the frame body 3 is installed on the crossbeam 2 and can move back and forth on the crossbeam 2. This reciprocating design allows the frame body 3 to cover the entire length of the crossbeam 2, expanding the cleaning coverage. There are two angle-shaped members 5, one on each side of the frame body 3. This symmetrical arrangement ensures that both sides can be effectively cleaned during the movement of the frame body 3. The design of the inclined surface 502 prevents dust from accumulating above the angle-shaped member 5.

[0052] Further, the angle-shaped member 5 and the crossbeam 2 have a gap therebetween, and the cleaning system further comprises an adapter 6 arranged on the angle-shaped member 5 and located in the gap below the angle-shaped member 5. The adapter 6 is used to abut against the upper end surface of the crossbeam 2, and the adapter 6 is elastic.

[0053] In this embodiment, a gap is provided between the angle-shaped member 5 and the crossbeam 2 to ensure that the angle-shaped member 5 does not directly contact the surface of the crossbeam 2, avoiding wear or jamming due to friction between hard materials. The adapter 6 is arranged below the angle-shaped member 5 and located in the gap. Its main function is to abut against the upper end surface of the crossbeam 2, serving as a buffer and protector. The adapter 6 is made of an elastic material (preferably rubber), which has high hardness to deal with hard impurities and also has a certain elasticity to shrink and deform when encountering large resistance. As a preferred embodiment, a winch 13 is used to pull the frame body 3, and two winches 13 are arranged on both sides of the rotary kiln 1 to jointly pull the frame body 3, achieving the reciprocating movement of the frame body 3. The winch 13 pulls the frame body 3, allowing the frame body 3 to move back and forth along the crossbeam 2, ensuring that the cleaning system covers the entire length of the crossbeam 2 and performs effective cleaning work.

[0054] When the accumulated dust or other impurities on the cross beam 2 become hard and cannot be cleaned by conventional methods, the elastic properties of the adapter 6 can absorb part of the impact force, preventing the frame 3 from being stuck. Even in extreme cases, the rubber material of the adapter 6 can contract itself, ensuring the frame 3 continues to move normally, avoiding downtime due to hard obstacles. The presence of the gap and the use of the adapter 6 reduce direct contact between the angle piece 5 and the cross beam 2, reducing wear and tear between the two, extending the service life of the equipment. The elastic adapter 6 can deform appropriately when encountering greater resistance, avoiding permanent damage to the angle piece 5 and the cross beam 2, protecting critical components. Even if there are hard impurities on the surface of the cross beam 2 that are difficult to clean, the elastic design of the adapter 6 still allows the frame 3 to move smoothly, allowing the scraper 4 to continue normal cleaning of the kiln wall, ensuring the continuity and efficiency of the overall cleaning process. The adapter 6 moves synchronously with the frame 3, adapting to changes in the surface of the cross beam 2 in real time, reducing the need for downtime cleaning and improving the overall efficiency of the system. Due to the harsh internal environment of the rotary kiln 1, dust is easily accumulated and may have a large hardness, and the design of the adapter 6 allows the cleaning system to better adapt to this complex working condition, enhancing the reliability and adaptability of the system. The elastic adapter 6 provides additional stability and cushioning, ensuring that the frame 3 moves more smoothly, reducing the risk of vibration and deviation.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, which should be covered by the claims of the present application.
