Description
Technical Field
[0001] This utility model relates to the field of cleaning technology for mixing machines, specifically, to an auxiliary cleaning device for cleaning the inside of a mixing machine. Background Technology
[0002] Rotary kilns, as important industrial equipment, are widely used in cement, metallurgy, chemical and other industries. One of their core functions is to achieve full contact and mixing of material particles through continuous rotation, causing materials to tumble, slide and jump within the kiln. However, the working environment of rotary kilns is usually harsh, generating a large amount of dust during material processing. This dust not only affects the health of operators but may also cause respiratory diseases. Furthermore, dust accumulation reduces equipment efficiency and increases safety hazards. Materials such as ores and clay easily adhere to the kiln walls, forming crusts or deposits. If these residues are not cleaned in time, they can lead to uneven heat transfer, affecting product quality. As the crusting gradually increases, it also increases the energy required to drive the rotary kiln, wasting energy and, in severe cases, damaging the equipment.
[0003] The existing rotary kiln automatic cleaning device can move along the axis of the rotary kiln inside the rotary kiln. However, the movement of the cleaning device depends on the support components. The support components are in the environment inside the rotary kiln for a long time, and substances such as ore and clay will adhere to them. Over time, the accumulation will affect the movement of the entire device. Utility Model Content

[0043] Reference Figures 1-5This utility model proposes an auxiliary cleaning device for cleaning the inside of a mixer, used to clean residues on the moving path of a cleaning component 400. The cleaning component 400 is used to clean the inner wall of a rotary kiln 200 and includes a crossbeam 100, which is mounted outside the rotary kiln 200 and extends into the rotary kiln 200; a movable frame 300 is movably mounted on the crossbeam 100, and the moving direction of the movable frame 300 is parallel to the axis of the rotary kiln 200; the cleaning component 400 is mounted on the movable frame 300 and is used to clean residues on the inner wall of the rotary kiln 200; there are two pushers 500, with their ends respectively mounted at both ends of the movable frame 300, and the bottom of the pushers 500 abuts against the upper end face of the crossbeam 100, and the pushers 500 are used to clean residues on the surface of the crossbeam 100.
[0044] In this embodiment, the crossbeam 100 is made of high-strength, high-temperature resistant, and corrosion-resistant material. It spans the outside of the rotary kiln 200 and extends into the kiln via a stable support structure. The movable frame 300 is mounted on the crossbeam 100 via slide rails, rollers 620, and other structures, allowing it to move smoothly along the length of the crossbeam 100. The cleaning component 400 is securely and adjustablely mounted on the movable frame 300; its position and angle can be adjusted as needed to effectively clean residue from the inner wall of the rotary kiln 200. Two pushers 500 are respectively mounted at both ends of the movable frame 300. The bottom of the pusher 500 is designed to fit tightly against the upper surface of the crossbeam 100, for example, by using a flat scraper structure.
[0045] As the moving frame 300 moves the cleaning component 400 along the crossbeam 100, the bottom of the pusher 500 is always in contact with the upper surface of the crossbeam 100, pushing away residual materials such as ore and clay on the surface of the crossbeam 100, keeping the surface of the crossbeam 100 clean, and ensuring the smooth movement of the moving frame 300.
[0046] By promptly cleaning the residue on the surface of the crossbeam 100 using the pusher 500, the problem of residue accumulation affecting the movement of the movable frame 300 is effectively solved, ensuring the stability and reliability of the cleaning device's operation. The pusher 500 reduces equipment failures caused by obstruction of the support structure, lowers maintenance costs and downtime, and improves production efficiency.
[0047] Furthermore, the pusher 500 includes a conical block 510, which is disposed on the movable frame 300. The tip of the conical block 510 faces both ends of the crossbeam 100, and the bottom of the conical block 510 has a gap with the upper end face of the crossbeam 100. One end of the film 520 is disposed on the conical block 510, and the other end abuts against the upper end face of the crossbeam 100.
[0048] In this embodiment, conical blocks 510 are respectively installed at both ends of the movable frame 300. The conical blocks 510 are securely mounted on the movable frame 300 by welding, screwing, or other methods. The tips of the conical blocks 510 face both ends of the crossbeam 100, and a certain gap is maintained between their bottoms and the upper end surface of the crossbeam 100. One end of the film 520 is fixed to the conical block 510 by riveting, bonding, or other methods, while the other end hangs down naturally and abuts tightly against the upper end surface of the crossbeam 100. During the movement of the movable frame 300, the film 520 slides on the upper end surface of the crossbeam 100 as the movable frame 300 moves. Due to the flexibility and elasticity of the film 520, it can adapt to the unevenness of the surface of the crossbeam 100 and effectively scrape away residual substances from the surface of the crossbeam 100.
[0049] A conical block 510 is used, with its tip facing the moving direction of the moving frame 300. This tip reduces the moving resistance of the moving frame 300, pushing away some residue from the side of the crossbeam 100. The flexible contact between the film 520 and the upper surface of the crossbeam 100 effectively cleans residue while reducing wear on the surface of the crossbeam 100. The maintained gap prevents excessive friction from direct contact between the conical block 510 and the crossbeam 100, thus improving the overall service life of the pusher 500. This pusher 500 has a simple structure, is easy to install and maintain, and reduces equipment cost and maintenance difficulty.
[0050] Furthermore, the crossbeam 100 is an I-beam with grooves 110 on both sides, and also includes a plate 610. The plate 610 is disposed on both sides of the movable frame 300 and covers the grooves 110. There are several rollers 620, which are rotatably disposed on the plate 610 and the movable frame 300, and roll against the upper and lower end surfaces of the crossbeam 100.
[0051] In this embodiment, the crossbeam 100 adopts an I-beam structure. The I-beam can accommodate the excessive length of the rotary kiln 200, and the middle of the I-beam is not easily bent. The crossbeam 100 has grooves 110 on both sides. Plates 610 are installed on both sides of the movable frame 300. The plates 610 are fixed to the movable frame 300 by bolts, welding, or other methods, and their positions precisely cover the grooves 110 of the I-beam. Several rollers 620 are respectively mounted on the plates 610 and the movable frame 300 via rotating shafts. Some of the rollers 620 roll against the upper surface of the crossbeam 100, while others roll against the lower surface of the crossbeam 100.
[0052] As the moving frame 300 moves, the rollers 620 rotate accordingly, allowing the moving frame 300 to slide smoothly along the crossbeam 100. Simultaneously, the plate 610 effectively prevents external impurities from entering the groove 110, reducing interference with movement. The I-beam structure enhances the strength and stability of the crossbeam 100, better bearing the weight of the moving frame 300 and the cleaning component 400, as well as the impact forces during operation. The plate 610's shielding of the groove 110 protects the structural integrity of the crossbeam 100, reducing the possibility of debris accumulation and damage within the groove 110. The arrangement of multiple rollers 620 disperses the pressure between the moving frame 300 and the crossbeam 100, reducing frictional resistance, making movement smoother, and extending the service life of both the rollers 620 and the crossbeam 100.
[0053] Furthermore, it also includes a first cleaning brush 700, of which there are several, and the several first cleaning brushes 700 are respectively disposed on both sides of the movable frame 300. The cleaning end of the first cleaning brush 700 abuts against the side of the crossbeam 100, and the first cleaning brush 700 is used to clean the side of the crossbeam 100.
[0054] In this embodiment, several first cleaning brushes 700 are respectively installed on both sides of the movable frame 300 via mounting bases or other fixing methods. The positions of these first cleaning brushes 700 are reasonably arranged to ensure that their cleaning ends can closely abut against the side of the crossbeam 100. As the movable frame 300 moves along the crossbeam 100, the first cleaning brushes 700 clean the side of the crossbeam 100 with the movement of the movable frame 300, removing impurities and residues attached to the side.
[0055] The first cleaning brush 700 is designed to thoroughly clean the crossbeam 100, including easily overlooked sides, preventing impurities from accumulating on the sides of the crossbeam 100 and affecting the stability of the moving frame 300. This helps maintain the overall cleanliness of the crossbeam 100, extends its service life, and reduces movement obstruction and equipment wear caused by side contamination.
[0056] Furthermore, it also includes a second cleaning brush 800, of which there are several. The second cleaning brush 800 is disposed at the bottom of the plate 610, and the cleaning end of the second cleaning brush 800 abuts against the bottom of the crossbeam 100. The second cleaning brush 800 is used to clean the lower end surface of the crossbeam 100.
[0057] In this embodiment, several second cleaning brushes 800 are distributed at the bottom of the plate 300 using a fixed bracket or other suitable installation method. The positions of these second cleaning brushes 800 are designed to ensure that their cleaning ends can accurately and tightly contact the bottom of the crossbeam 100. When the movable frame 300 moves on the crossbeam 100, the second cleaning brushes 800 will sweep the lower surface of the crossbeam 100 as the movable frame 300 moves, cleaning away dust, debris, and other contaminants adhering to the lower surface.
[0058] The addition of the second cleaning brush 800 ensures timely and effective cleaning of the lower surface of the crossbeam 100, preventing the accumulation of debris and thus guaranteeing the stability and smoothness of the movement of the mobile frame 300. This further improves the all-around cleaning of the crossbeam 100, helping to maintain the good operating condition of the entire device and extend its service life.
[0059] Furthermore, the first cleaning brush 700 includes a first clamping plate 710, which has two clamping plates. The ends of the two clamping plates 710 that are close to each other have a first arc-shaped groove 711. When the two clamping plates 710 are close to each other, the first arc-shaped grooves 711 on the two clamping plates 710 form a first clamping space. The first clamping space is used to clamp the first filament brush 720, which is used to clean the side of the crossbeam 100.
[0060] In this embodiment, the first cleaning brush 700 is composed of two first clamping plates 710. The two first clamping plates 710 have similar structures, and each of them has a first arc-shaped groove 711 machined at one end that is close to the other.
[0061] During installation, the two first clamping plates 710 are brought close together, so that the two first arc-shaped grooves 711 are aligned and combined to form a first clamping space. Then, the first bristle brush 720 is placed within the first clamping space, and the two first clamping plates 710 are fixed together using bolts, rivets, or other fastening methods, thereby clamping the first bristle brush 720. During use, the bristles of the first bristle brush 720 contact the side of the crossbeam 100, achieving cleaning of the side of the crossbeam 100.
[0062] The design of the first clamping plate 710 and the first clamping space facilitates the installation and replacement of the first bristle brush 720, improving maintenance convenience. It ensures that the first bristle brush 720 is firmly fixed between the first clamping plates 710, preventing loosening or detachment and guaranteeing the stability and reliability of the cleaning operation.
[0063] It should be further explained that the first wire brush 720 can use loose steel bars, which is not only easy to obtain, but also has a lower cost.
[0064] Furthermore, the second cleaning brush 800 includes a second clamping plate 810, which has two clamping plates. The ends of the two clamping plates 810 that are close to each other have a second arc-shaped groove 811. When the two clamping plates 810 are close to each other, the second arc-shaped grooves 811 on the two clamping plates 810 form a second clamping space. The second clamping space is used to clamp the second wire brush 820, which is used to clean the lower end face of the crossbeam 100.
[0065] In this embodiment, the structure of the second cleaning brush 800 is similar to that of the first cleaning brush 700. Each of the two second clamping plates 810 has a second arc-shaped groove 811 at one end close to the other. During assembly, the two second clamping plates 810 are brought together, at which point the two second arc-shaped grooves 811 fit together to form a second clamping space. The second bristle brush 820 is placed in the second clamping space, and then the two second clamping plates 810 are fastened together using screws, rivets, or other connectors to clamp and fix the second bristle brush 820. In actual operation, the bristles of the second bristle brush 820 contact the lower end face of the crossbeam 100, performing the cleaning task on the lower end face of the crossbeam 100.
[0066] The design of the second clamping plate 810 and the second clamping space simplifies the installation and removal of the second bristle brush 820, facilitating subsequent maintenance and replacement. It securely clamps the second bristle brush 820, ensuring it does not loosen or shift during operation and guaranteeing stable cleaning results.
[0067] Furthermore, it also includes a plurality of protrusions 900, which are disposed on the side of the crossbeam 100 and are used to abut against the first filament brush 720.
[0068] In this embodiment, a plurality of protrusions 900 are evenly distributed on the side of the crossbeam 100 through welding, inlaying, or other methods. The position and number of the protrusions 900 are reasonably arranged according to actual needs to ensure that they can fully contact the first bristle brush 720. When the first bristle brush 720 moves with the moving frame 300, it will collide and rub against these protrusions 900. When the first bristle brush 720 contacts the protrusions 900, an impact is generated, which can clean the adhering substances on the first bristle brush 720. When the first bristle brush 720 leaves the protrusions 900, it forms a contact with the side of the crossbeam 100, which can again clean the adhering substances on the first bristle brush 720. The protrusions 900 enable the self-cleaning of the first bristle brush 720, thereby improving the service life and cleaning effect of the first bristle brush 720.
[0069] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
