Description

TECHNICAL FIELD

[0001] The utility model relates to a cleaning system for a mixer. BACKGROUND

[0002] As an important industrial equipment, rotary kiln is widely used in cement, metallurgy, chemical industry and other industries. One of its core functions is to achieve full contact and mixing between particles through continuous rotary motion, which makes materials roll, slide and jump in the kiln.

[0003] However, the working environment of the rotary kiln is usually harsh, and a large amount of dust is generated during the material processing process. These dust not only affects the health of the operators, but also may cause respiratory diseases. In addition, dust accumulation will reduce the efficiency of the equipment and increase the safety hazards. Ore, clay and other materials are easy to adhere to the kiln wall, forming a crust or accumulated material. If these residues are not cleaned in time, it will cause uneven heat transfer, affect product quality, and as the crust gradually increases, it will also require more energy to drive the rotary kiln to rotate, wasting energy, and in severe cases, it will also damage the equipment.

[0004] The traditional cleaning method mainly relies on manual cleaning inside the kiln. The time of workers entering the kiln is limited each time, the cleaning speed is slow, and the overall work efficiency is low. Frequent shutdown for manual cleaning will also seriously affect the continuity of production and increase the production cost. Dust and other factors make the interior of the rotary kiln a highly dangerous workplace. When workers carry tools to clean inside the kiln, they face a high safety risk, and the use of tools by workers for cleaning is heavy physical labor, and the kiln is a closed environment, so workers are prone to hypoxia and other hazards during long-term work. Therefore, multiple workers need to enter the kiln in batches for work, each group of workers controls the work time, for example, between 30 minutes and 60 minutes, and the rotary kiln needs to be kept rotating slowly during the cleaning process, and the workers also need to keep moving horizontally. However, because the rotary kiln is rotating, heavy impurities may fall from the upper part of the rotary kiln, which may injure the workers. Even if protective measures are taken, these potential threats cannot be completely eliminated. A large amount of dust generated during the cleaning process can cause serious damage to the respiratory system of workers, and long-term exposure may cause occupational diseases. Because workers need to be regularly arranged for cleaning, enterprises have to invest a lot of resources in training, equipment and medical care. At the same time, frequent manual intervention also increases the wear rate of the equipment and increases the maintenance cost. SUMMARY

[0044] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0045] Referring to Figures 1-6 , a cleaning system for a mixer is proposed for cleaning the inner wall of a rotary kiln 1, comprising: a cross beam 2, the cross beam 2 is erected outside the rotary kiln 1 and extends into the rotary kiln 1; the frame body 3 is movably arranged on the cross beam 2, and the frame body 3 moves into or out of the rotary kiln 1; the scraper 4 is arranged on the frame body 3 and used for cleaning the inner wall of the rotary kiln 1; 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, the angle part 501 faces away from the frame body 3, and the bottom is close to the surface of the cross beam 2.

[0046] In the embodiment, the cross beam 2 is erected outside the rotary kiln 1 and extends into the rotary kiln 1, as shown in Figure 1 and Figure 2 , Figure 2In order to clearly show the relationship between the frame body 3 and the beam 2, the volume of the beam 2 is reduced. It serves as the supporting structure of the entire cleaning system, ensuring the stable installation and operation of other components. The frame body 3 is movably arranged on the beam 2 and can slide back and forth on the beam 2. Through the driving device, the frame body 3 can be flexibly moved into or out of the rotary kiln 1. When cleaning is needed, the frame body 3 enters the rotary kiln 1; after cleaning is completed, the frame body 3 moves out of the rotary kiln 1, facilitating maintenance and inspection. The scraper 4 is arranged on the frame body 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 skin and accumulated material on the inner wall of the rotary kiln 1. The corner piece 5 is arranged on the frame body 3 and located in the moving direction of the frame body 3.

[0047] The corner portion 501 of the corner piece 5 is specially used for cleaning the dust and slag accumulated on the upper end surface of the beam 2. When the frame body 3 moves along the beam 2, the corner portion 501 of the corner piece 5 is used to scrape off the accumulated material on the surface of the beam 2, ensuring that the frame body 3 can move smoothly and avoiding being blocked by the accumulated impurities. With the movement of the frame body 3, the corner 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 corner portion 501 can always clean the surface of the beam 2 whether the frame body 3 moves forward or backward, reducing the risk of jamming or failure caused by accumulated material.

[0048] Through the movement arrangement 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 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 with a large amount of 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.

[0049] Further, the frame body 3 is movably arranged on the beam 2, and the corner piece 5 has two, which are located on both sides of the frame body 3; the corner piece 5 has an inclined surface 502 located at the upper portion of the corner piece 5, which gradually decreases in height from close to the frame body 3 to far away from the frame body 3.

[0050] In this embodiment, the frame body 3 is installed on the cross beam 2 and can move back and forth on the cross beam 2. This reciprocating design allows the frame body 3 to cover the entire length of the cross beam 2, expanding the cleaning coverage. There are two angle-shaped pieces 5, one on each side of the frame body 3. This symmetrical arrangement ensures that both sides are 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 piece 5.

[0051] Further, there is a gap between the angle-shaped piece 5 and the cross beam 2, and the cleaning system further comprises a connecting piece 6. The connecting piece 6 is arranged on the angle-shaped piece 5, below the angle-shaped piece 5 and in the gap. The connecting piece 6 is used to abut against the upper end surface of the cross beam 2, and the connecting piece 6 is elastic. There are two winches 13, one on each side of the rotary kiln 1, which are used to pull the frame body 3.

[0052] In this embodiment, a gap is provided between the angle-shaped piece 5 and the cross beam 2 to ensure that the angle-shaped piece 5 does not directly contact the surface of the cross beam 2, avoiding wear or jamming due to friction between hard materials. The connecting piece 6 is arranged below the angle-shaped piece 5 and in the gap. Its main function is to abut against the upper end surface of the cross beam 2, serving as a buffer and protector. The connecting piece 6 is made of elastic material (preferably rubber material), which has high hardness to resist the accumulation of hard impurities and has certain elasticity to shrink and deform when encountering large resistance. Two winches 13 are arranged on both sides of the rotary kiln 1 to pull the frame body 3, achieving the reciprocating movement of the frame body 3. The winch 13 pulls the frame body 3 to move the frame body 3 back and forth along the cross beam 2, ensuring that the cleaning system covers the entire length of the cross beam 2 and performs effective cleaning work.

[0053] When the accumulated dust or other impurities on the 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 that 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 the direct contact between the angle piece 5 and the beam 2, reducing wear between the two, prolonging 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 beam 2, protecting the key components. Even if there are hard impurities on the surface of the beam 2 that are difficult to clean, the elastic design of the adapter 6 still allows the frame 3 to move smoothly, enabling 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 the changes on the surface of the beam 2 in real time, reducing the need for downtime cleaning and improving the overall work 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, the design of the adapter 6 enables the cleaning system to better adapt to such complex working conditions, 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 during the process, reducing the risk of vibration and deviation.

[0054] Further, it also includes: a rod seat 7 is arranged on the frame 3; an adjusting rod 8 is arranged on the rod seat 7 in a lifting manner, and the scraper 4 is arranged on the adjusting rod 8 and arranged on the frame 3 through the adjusting rod 8. The scraper 4 has a fixed part 401 and a scraping part 402, and the scraping part 402 has an included angle with the fixed part 401; the scraper 4 also has a handle part 403, and the handle part 403 also has a second included angle with the fixed part 401, and the handle part 403 and the scraping part 402 are both curved towards the same side of the fixed part 401.

[0055] In this embodiment, the rod seat 7 is arranged on the frame 3, providing a stable mounting platform. The adjusting rod 8 is arranged on the rod seat 7 in a lifting manner, allowing its 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. The double-angle design and curved shape of the scraper 4 enable it to better fit the different curvatures of the kiln wall, ensuring full coverage during the cleaning process and improving the cleaning effect.

[0056] Further, the beam 2 is of an I-shaped type and has grooves 201 on both sides, and further includes: a plate 9 arranged on both sides of the frame 3 and shielding the grooves 201; a plurality of rollers 10 are arranged in a rotating manner on the plate 9 and the frame 3 and are in rolling abutment with the upper end face and the lower end face of the beam 2.

[0057] In this embodiment, the cross beam 2 adopts an I-shaped design, and has grooves 201 on both sides. This design not only provides higher strength and rigidity, but also provides a stable track for the rolling of the rollers 10. The plate 9 can also prevent impurities such as dust and slag from directly contacting the rollers 10 to a certain extent, affecting the rollers 10, and avoiding jamming or failure caused by the accumulation of impurities.

[0058] Further, it also includes a side plate 11, which is arranged on the frame 3 and located on one side of the cross beam 2 with a gap between the cross beam 2.

[0059] In this embodiment, the side plate 11 is arranged on the frame 3 and located on one side of the cross beam 2 with a gap between the cross beam 2. The main function of the side plate 11 is to limit the frame 3 to ensure that the rollers 10 do not fall off when rolling on the frame 3, improving the stability of the system. The design of the side plate 11 allows the frame 3 to move freely within a small range, adapting to slight deviations without affecting the overall operation. The distance between the side plate 11 and the side of the cross beam 2 is less than the distance from the roller 10 to the side of the cross beam 2. This design ensures that even if the frame 3 deviates greatly, the side plate 11 can limit the movement in time and enhance the adaptability and reliability of the system.

[0060] Further, the plate 9 has a wire hole 901, which is vertically spaced, and further includes a wire brush 12 arranged in the wire hole 901 and extending to the side wall of the groove 201 for scraping and cleaning the groove 201.

[0061] In this embodiment, the wire brush 12 is arranged in the wire hole 901 of the plate 9, and can continuously scrape the side wall of the groove 201 as the frame 3 moves, ensuring that the inside of the groove 201 is always clean and reducing the risk of impurities accumulating. Since the wire holes 901 are vertically spaced, multiple wire brushes 12 can cover different heights of the groove 201, ensuring that the entire side wall of the groove 201 can be effectively cleaned.

[0062] Further, it also includes an electric control controller module 14, which is electrically connected with the winch 13 for controlling the pulling speed of the winch 13 on the frame 3.

[0063] In this embodiment, the electric control controller module 14 is electrically connected with the hoist 13, for accurately controlling the pulling speed of the hoist 13 to the frame body 3. By adjusting the running parameters of the hoist 13, such as the motor speed and the traction force, it is ensured that the moving speed of the frame body 3 on the cross beam 2 meets the actual demand. The travel switch is used for detecting the position of the frame body 3 and feeding back the position information to the electric control controller module 14. When the frame body 3 reaches the predetermined position, the travel switch triggers a signal, and the electric control controller module 14 adjusts the running state of the hoist 13 according to the received signal, such as deceleration, stop or reverse running. In summary, the electric connection design of the electric control controller module 14 and the hoist 13 realizes the accurate control of the pulling speed of the frame body 3, and significantly improves the automation degree and the running efficiency of the system.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. 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 present application, which should be covered in the scope of the claims of the present application.
