Description

Technical Field

[0001] This utility model relates to the field of tunnel kiln technology, and more specifically, to a rapid feeding device for a high-temperature tunnel kiln. Background Technology

[0002] A high-temperature tunnel kiln is a continuous industrial kiln that uses a tunnel structure to move materials in a fixed direction within a high-temperature environment, completing sintering, firing, and other physicochemical changes to form finished products with specific properties. Its core advantages lie in efficient continuous production, precise temperature and atmosphere control, and low energy consumption. It is widely used in industrial fields involving various processes such as drying, sintering, annealing, and quenching. During operation, materials are fed into the kiln body by a conveyor belt in the transmission system, moving sequentially along the preheating zone, firing zone, and cooling zone. The preheating zone uses residual heat from the kiln to heat the materials and remove volatiles. The firing zone uses high temperatures to sinter the materials, during which the atmosphere can be controlled to produce oxidation or reduction. The cooling zone cools the materials by blowing air. The system is linked with a PLC via thermocouples to precisely control the temperature of each zone and the material transport rhythm, achieving continuous high-temperature sintering operations. Since the material processing and unloading directly affect the convenience and continuity of processing, it is necessary to perform unloading operations.

[0003] In related technologies, during the use of tunnel kilns, inclined feeding guides are generally installed to feed and guide the processed materials.

[0004] However, in the current use of tunnel kilns, since the feeding guide plate is generally an integral piece with a fixed feeding range and does not contact the conveyor belt, when small-sized materials are fed, the materials are prone to stagnate in the gap between the conveyor belt and the feeding guide plate, resulting in incomplete material feeding, interfering with the feeding of subsequent materials, and affecting the feeding efficiency and effect of the tunnel kiln.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a high-temperature tunnel kiln rapid feeding device, including a tunnel kiln 1 and a feeding guide mechanism. A support 2 is installed at the bottom of the tunnel kiln 1, and a conveyor belt 3 is installed at the bottom inside the tunnel kiln 1. The feeding range can be adjusted according to the actual feeding requirements of the material conveyed by the conveyor belt 3, and the conveyor belt 3 is in contact with the surface of the conveyor belt 3 to provide continuous feeding guidance for the material during the feeding process. This avoids material stagnation during the feeding process, which would interfere with the subsequent feeding and lead to incomplete feeding. Therefore, the feeding efficiency and feeding effect of the conveyor belt 3 and the tunnel kiln 1 are improved.

[0031] Reference Figures 1-4 In a preferred embodiment, the material feeding guide mechanism includes a material feeding frame 4, which is movably connected to both sides of the left side of the tunnel kiln 1. A guide plate 5 is movably connected to the inner side of the material feeding frame 4. A trough 6 is opened inside the guide plate 5, and a trough 7 is movably connected inside the trough 6. A material feeding adjustment mechanism is located outside the material feeding frame 4. After the material feeding frame 4 is moved to the left side of the tunnel kiln 1, the spacing between the guide plates 5 is changed by moving the material feeding frame 4 according to the material feeding requirements. At this time, the trough 7 moves inside the trough 6, connecting the guide plates 5 and making the guide plates 5 contact the conveyor belt 3, thus allowing the material conveyed by the conveyor belt 3 to be fed... The continuous contact feeding guide ensures efficient material feeding. The feeding adjustment mechanism includes an adjustment port 8, an adjustment frame 9, and an adjustment groove 10. The adjustment port 8 is located on the outside of the feeding frame 4, and the adjustment frame 9 is movably connected to the inside of the adjustment port 8. The adjustment groove 10 is located on the outside of the guide plate 5, and the inside of the adjustment frame 9 is located inside the adjustment groove 10. This allows for adjustment of the connection between the feeding frame 4 and the guide plate 5, enabling users to adjust the height and guiding angle of the guide plate 5 according to material requirements. This avoids situations where the guide plate 5 is difficult to adjust or separates from the feeding frame 4, thus improving the flexibility of the guide plate 5.

[0032] Reference Figures 2-3In a preferred embodiment, magnetic strips 11 are embedded and connected to both sides of the inner wall of the adjustment port 8, and magnetic sheets 12 that are magnetically connected to the magnetic strips 11 are embedded and connected to both sides of the adjustment frame 9. The adjustment frame 9 can be used to magnetically attract and stabilize the guide plate 5 and the unloading frame 4 after adjustment, thus avoiding the instability of the guide plate 5 after adjustment. This improves the ease of operation of the guide plate 5. A stud 13 is fixedly connected to the outer side of the adjustment frame 9, and a threaded sleeve 14 is threaded to the surface of the stud 13. The adjustment frame 9 can be used to thread-tightly fix the guide plate 5 and the unloading frame 4 after adjustment, thus improving the ease of positioning the guide plate 5.

[0033] Reference Figures 2-4 In a preferred embodiment, a lifting frame 15 is fixedly connected to the outside of the unloading frame 4, and a lifting plate 16 located on the top of the screw sleeve 14 is movably connected inside the lifting frame 15. This allows for the lifting and closing of the adjustment port 8 at the top of the adjustment frame 9, thus improving the ease of closing the adjustment port 8. A screw groove 17 is provided on the rear side of the unloading frame 4, and a screw rod 18 is threaded inside the screw groove 17. This provides a medium for users to adjust the unloading frames 4, thus improving the ease of adjustment between the unloading frames 4.

[0034] Reference Figures 2-4 In a preferred embodiment, a connecting groove 19 is provided on the rear side of the unloading rack 4, located behind the screw groove 17. A connecting frame 20 is movably connected inside the connecting groove 19. The front side of the connecting frame 20 is fixedly connected to the rear side of the screw 18, which can connect the screw 18 and the unloading rack 4 and provide the user with operating space to rotate the screw 18. This improves the operating stability and convenience of the screw 18. A translation groove 21 is provided on the rear side of the unloading rack 4, located at the top of the screw groove 17. A translation column 22 is movably connected inside the translation groove 21 and fixedly connected to the unloading rack 4. This can guide the adjustment connection between the unloading racks 4, thus improving the smoothness of the adjustment of the unloading rack 4.

[0035] Specifically, the working process or working principle of this high-temperature tunnel kiln rapid feeding device is as follows: During use, the feeding rack 4 is placed at the feeding end of the conveyor belt 3, and the feeding rack 4 is brought into contact with the tunnel kiln 1. Then, according to the required feeding range of the material, the connecting frame 20 is held in conjunction with the connecting groove 19 to rotate the screw 18, causing the screw 18 to engage with the screw groove 17. Through the connecting frame 20 and the connecting groove 19, a threaded thrust is applied between the feeding rack 4 and the guide plate 5, causing the feeding rack 4 to move. The distance between the feeding rack 4 and the guide plate 5 is adjusted. At this time, the translation column 22 follows the feeding rack 4 within the translation groove 21. The movement of the guide plate 5 involves adjusting and guiding the material feeding frame 4, while the expansion plate 7 moves within the expansion groove 6 to extend the connection between the guide plates 5. Then, based on the material feeding position requirements of the conveyor belt 3, the guide plates 5 are manually moved left and right and up and down to adjust their position in a cross shape, ensuring the right side of the guide plate 5 contacts the surface of the conveyor belt 3, minimizing the gap between them. Simultaneously, the adjustment frame 9 moves through the adjustment groove 10, following the guide plate 5 within the adjustment opening 8, to adjust and connect the guide plate 5 to the material feeding frame 4. The stud 13 drives the sleeve 14 to move up and down with the guide plate 5. The lifting plate 16, affected by the changing position of the sleeve 14 and its own weight, moves with the sleeve 14 outside the adjustment port 8, closing the gap at the top between the adjusted adjustment port 8 and the adjustment frame 9. At this time, the magnetic sheet 12, in conjunction with the magnetic strip 11, uses the adjustment frame 9 and adjustment groove 10 to magnetically stabilize the position between the guide plate 5 and the unloading frame 4. Then, by holding the sleeve 14 and rotating the stud 13, an inward threading force is applied to the sleeve 14, causing it to contact and abut against the unloading frame 4 for a tight fit. The entire frame 9 is used to tighten the threaded position between the adjusted guide plate 5 and the unloading frame 4. When the conveyor belt 3 transports external materials through the tunnel kiln 1 for processing, and then transports the materials to the unloading end for unloading, the guide plate 5 and the expansion plate 7 come into contact with the materials transported on the surface of the conveyor belt 3, ensuring uninterrupted contact and efficient unloading. This allows the materials to be guided by the guide plate 5 and the expansion plate 7, quickly separating from the conveyor belt 3 and moving downwards, resulting in smooth unloading. A material box located at the bottom of the guide plate 5 can be placed inside the unloading frame 4 for centralized handling of the unloaded materials.

[0036] It should be noted that the tunnel kiln 1, the support 2 and the conveyor belt 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
