Description

Technical Field

[0001] This utility model relates to the field of crucible unloading and cleaning technology in industrial production, and in particular to a multifunctional automatic crucible unloading and cleaning device. Background Technology

[0002] In current industrial production processes, the process of filling mixed powdered raw materials into crucibles and continuously calcining them at high temperatures to remove impurities is widely used. Using cylindrical containers—crucibles—made of refractory materials for calcination offers numerous advantages. The filled crucibles can be arranged on movable kiln cars or stacked together for high-temperature calcination, making full use of space and improving the utilization rate of the production site. The calcined material is then fed and unloaded using a "negative pressure" method, achieving a degree of automation. Compared to traditional manual unloading methods, this significantly improves production efficiency, reduces labor costs, and ensures operational stability and consistency to a certain extent, facilitating large-scale industrial production.

[0003] However, due to the series of physical and chemical changes that occur after the material inside the crucible is calcined, it shrinks in volume, adheres, and clumps. During the material suction process, the operator needs to continuously use the suction head to crush and cut large pieces before suctioning them. Otherwise, large pieces are easily sucked in and block the suction pipe, affecting the continuity and stability of production. At the same time, the sintered material will stick to the inner wall of the crucible. Since the suction head cannot stick tightly to the inner wall of the crucible, a layer of material of varying thickness will remain on the inner wall of the crucible after suctioning. Manual cleaning is not only labor-intensive and time-consuming, but also difficult to clean completely. This directly affects the amount of material loaded into the crucible and reduces production efficiency. In addition, nearly 2 kilograms of material will remain at the bottom corners of the crucible after suctioning, which is usually impossible to clean completely, resulting in a waste of production capacity. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional automatic crucible unloading and wall cleaning device, aiming to solve the technical problems in the prior art where, after the material inside the crucible undergoes a series of physical and chemical changes, it shrinks in volume, adheres, and clumps. During the material suction process, the operator needs to continuously crush and cut large pieces with the "suction head" before suctioning, otherwise large pieces are easily sucked in and block the suction pipe, affecting the continuity and stability of production. At the same time, the sintered material will stick to the inner wall of the crucible. Since the suction head cannot stick tightly to the inner wall of the crucible, a layer of material of varying thickness will remain on the inner wall of the crucible after suctioning. Manual cleaning is not only labor-intensive and time-consuming, but also difficult to clean completely, which directly affects the amount of material loaded into the crucible and reduces production efficiency. In addition, nearly 2 kilograms of accumulated material will remain at the bottom corners of the crucible after suctioning, which is usually impossible to clean completely, resulting in wasted production capacity.

[0005] To achieve the above objectives, this utility model employs a multifunctional automatic crucible unloading and wall-cleaning device, comprising a frame and a track base. Multiple multifunctional automatic crucible unloading and wall-cleaning components are mounted on the frame. Each component includes a lifting and hoisting component and a multifunctional shield tunneling crusher suction head. The upper part of the suction head is a suction pipe, and the lower part is a transmission outer pipe. A driven gear is mounted on the transmission outer pipe. A mounting base is provided between the suction pipe and the transmission outer pipe via a bearing seat. A first reducer is mounted on the mounting base. The first reducer has a drive gear at its output end, which meshes with the driven gear. Multiple compressed air pipes are located below the mounting base, each equipped with an air nozzle. A shield crushing and suction head is located below the multi-functional shield crushing and suction head. A trolley is mounted on the track base, and a kiln car is mounted on the trolley. The frame is mounted on the track base, with the air nozzle positioned above the shield crushing and suction head. The mounting base is located at the moving end of the lifting and hoisting component, and the frame is mounted on the track base.

[0006] The lifting component includes a base plate and a slide rail. A second reducer is mounted on the base plate, and a drive sprocket is mounted on the output end of the second reducer. A slide block is slidably mounted on the slide rail, and a driven sprocket is mounted below the slide rail. The base plate is positioned above the slide rail, and a chain is provided between the drive sprocket and the driven sprocket. The slide block is also mounted on the chain. The slide rail is mounted on the frame, and the mounting base is mounted on the slide block.

[0007] The car-pulling component includes two track wheels and a car-pulling plate. Two track bodies are provided on the track seat. The two track wheels are respectively located below the car-pulling plate, and the two track wheels are also slidably located on the corresponding track bodies. The kiln car is located on the car-pulling plate.

[0008] The shield tunneling crushing and feeding head includes a shield crushing head and an adjusting seat. The shield crushing head is equipped with an air inlet and a crushing blade. The adjusting seat is equipped with a wire rope flexible wall cleaner. The shield crushing head is located below the adjusting seat, and the adjusting seat is located below the transmission outer tube.

[0009] An arc-shaped spring damper is provided between the track seat and the trolley plate.

[0010] This utility model discloses a multifunctional automatic crucible unloading and wall-cleaning device. This design targets large, agglomerated, or clump-forming material blocks. The crushing blades inside the shield tunneling crusher pre-crush the material blocks during the suction process, preventing large blocks from clogging the suction pipe and ensuring continuous and stable production. For residual material adhering to the inner wall of the crucible, a flexible steel wire rope wall cleaner on the adjusting seat removes the adhering material by rotating and brushing, simultaneously sucking away the fragments through the suction pipe, completely solving the problems of time-consuming, labor-intensive, and incomplete manual cleaning. For material accumulation at the bottom corners of the crucible, a compressed air pipe below the mounting base uses a blower to pulse-blow along the tangential direction of the inner wall, lifting the corner powder for suction head removal, thus avoiding wasted production capacity. This device significantly improves crucible unloading efficiency and loading capacity through the synergistic effect of automated crushing, flexible wall cleaning, and pulse cleaning technologies.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1 to 4 This utility model provides a multifunctional automatic crucible unloading and wall-cleaning device, including a frame 1 and a track base 2. Multiple multifunctional automatic crucible unloading and wall-cleaning components are mounted on the frame 1. Each component includes a lifting and hoisting member and a multifunctional shield tunneling crusher suction head. The upper part of the suction head is a suction pipe 3, and the lower part is a transmission outer pipe 4. A driven gear 5 is mounted on the transmission outer pipe 4. A mounting base 7 is provided between the suction pipe 3 and the transmission outer pipe 4 via a bearing seat 6. A first reducer 8 is mounted on the mounting base 7. The output end of the 8 is provided with a drive gear 9, and the drive gear 9 meshes with the driven gear 5. Multiple compressed air pipes 10 are provided below the mounting base 7, and each compressed air pipe 10 is provided with an air blowing nozzle 11. A shield crushing and suction head is provided below the multi-functional shield crushing and suction head. A trolley is provided on the track seat 2, and a kiln car 12 is provided on the trolley. The frame 1 is provided on the track seat 2, and the air blowing nozzle 11 is located above the shield crushing and suction head. The mounting base 7 is provided at the moving end of the lifting and hoisting component, and the frame 1 is provided on the track seat 2.

[0019] In this embodiment, by arranging multiple multifunctional crucible automatic unloading and wall cleaning components on the frame 1, synchronous automated unloading and wall cleaning operations of row crucibles (such as row crucibles on kiln car 12) can be realized, which greatly improves the production efficiency in multi-crucible scenarios and solves the problem of low efficiency in traditional single crucible operation.

[0020] Furthermore, the lifting component includes a base plate 13 and a slide rail 14. A second reducer 15 is disposed on the base plate 13, and a drive sprocket 16 is disposed at the output end of the second reducer 15. A slide block 17 is slidably disposed on the slide rail 14, and a driven sprocket 18 is disposed below the slide rail 14. The base plate 13 is disposed above the slide rail 14, and a chain 19 is disposed between the drive sprocket 16 and the driven sprocket 18. The slide block 17 is also disposed on the chain 19. The slide rail 14 is disposed on the frame 1, and the mounting base 7 is disposed on the slide block 17.

[0021] In this embodiment, the second reducer 15 drives the drive sprocket 16 to rotate the chain 19, causing the slide block 17 to rise and fall precisely along the slide rail 14, thus realizing the automated vertical movement of the multi-functional shield tunnel crushing and suction head. This structure ensures motion stability through sprocket and chain transmission, and achieves controllable speed in conjunction with the reducer, effectively solving the problem of inaccurate height adjustment in traditional manual operation, and improving the reliability and adaptability of equipment operation.

[0022] Furthermore, the pulling component includes two track wheels and a pulling plate 21. Two track bodies 22 are provided on the track seat 2. The two track wheels are respectively located below the pulling plate 21, and the two track wheels are also slidably located on the corresponding track bodies 22. The kiln car 12 is located on the pulling plate 21.

[0023] In this embodiment, the track wheel slides along the track body 22, driving the kiln car 12 on the trolley plate 21 to move precisely to the designated position, realizing the rapid docking of the crucible and the unloading device. This design ensures the accurate running trajectory of the kiln car 12 through track positioning, avoids positioning errors caused by manual handling, reduces operational intensity, and provides a stable foundation for subsequent automated unloading.

[0024] Furthermore, the shield tunneling crushing and feeding head includes a shield crushing head 20 and an adjusting seat 23. The shield crushing head 20 is provided with an air inlet 24 and a crushing blade 25. The adjusting seat 23 is provided with a wire rope flexible wall cleaner 26. The shield crushing head 20 is located below the adjusting seat 23, and the adjusting seat 23 is located below the transmission outer tube 4.

[0025] In this embodiment, the shield crusher head 20 pre-treats large pieces of clumps of material using the crushing blade 25 to prevent blockage of the suction pipe 3; the wire rope flexible wall cleaner 26 rotates with the transmission outer pipe 4, brushing away material adhering to the inner wall of the crucible and simultaneously sucking it away. This combined structure solves the two major problems of pipe blockage and inner wall residue at the same time, and is more efficient and cleaner than traditional manual cleaning.

[0026] Furthermore, a bow-shaped spring damper 27 is provided between the track seat 2 and the trolley plate 21.

[0027] In this embodiment, the bow-shaped spring damper 27 absorbs the vibration and impact during the operation of the kiln car 12 through elastic deformation, preventing the equipment from becoming loose or misaligned due to mechanical vibration. This structure significantly improves the stability of equipment operation, extends the service life of key components, reduces the failure rate, and ensures the stability of long-term continuous production.

[0028] In this invention, the kiln car 12, loaded with calcined material, is pushed onto the trolley plate 21 along the track body 22 via the track wheels, and the bow-shaped spring damper 27 is used to buffer the running vibration, ensuring that the kiln car 12 is accurately positioned directly below the multi-functional shield crusher suction head. Then, the second reducer 15 is started, and through the chain 19 of the driving sprocket 16 and the driven sprocket 18, the slide block 17 is driven to descend along the slide rail 14, causing the end of the shield crusher head 20 to... The crushing blade 25 contacts the material inside the crucible and pre-crushes it, while the steel wire rope flexible wall cleaner 26 brushes away the material adhering to the inner wall during rotation. The crushed material is sucked away by the suction pipe 3 under negative pressure, while the compressed air pipe 10 pulses along the tangential direction of the inner wall of the crucible through the blowing nozzle 11, lifting the accumulated material at the bottom corners and then sucking it away again. The entire process is achieved by the first reducer 8 driving the transmission outer pipe 4 to realize the synchronization of crushing and wall cleaning, and finally completes the automated, high-efficiency unloading and cleaning of the material inside the crucible.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
