Abstract
Description
Technical Field
[0001] This utility model provides a furnace outlet structure, belonging to the field of industrial silicon production technology, and particularly relates to a furnace outlet structure for efficient and intelligent industrial silicon furnace discharge. Background Technology
[0002] The furnace used in industrial silicon production is a key piece of equipment in the industrial silicon production process. It is a device that uses electrical energy to convert into heat energy. Current is introduced into the furnace through electrodes, causing raw materials such as silica to undergo a chemical reaction at high temperatures, thereby generating industrial silicon. Its main function is to provide the necessary high-temperature environment and reaction conditions for the smelting of industrial silicon, ensuring that raw materials such as silica can be efficiently converted into industrial silicon. At the same time, it can also control parameters such as temperature and atmosphere during the reaction process to improve production efficiency, ensure product quality, reduce production costs, and meet the requirements of different industrial sectors for the quality and purity of industrial silicon.
[0003] Existing furnace outlet structures are typically constructed from materials such as steel plates, high-alumina bricks, and self-baking carbon bricks, and are circular in design. This structure suffers from poor sealing in practical applications because it relies primarily on the stacking of refractory materials for sealing. These refractory materials are prone to cracking or loosening under high-temperature conditions, leading to gas leakage within the furnace and affecting the safety and stability of the production environment. Furthermore, the heat retention effect of this structure is also unsatisfactory. Due to the limited insulation performance of the refractory materials and the direct contact between the furnace outlet and the external environment, a significant amount of heat is lost from the outlet, reducing energy efficiency, increasing production costs, and potentially causing temperature fluctuations within the furnace, affecting the quality and production efficiency of industrial silicon. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this application provides a furnace outlet structure for efficient and intelligent tapping of industrial silicon, which solves the problems of poor sealing and serious heat loss of the existing furnace outlet structure, realizes the automation and intelligence of the tapping process, and effectively improves the efficiency and quality of industrial silicon production.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a furnace outlet structure for efficient and intelligent industrial silicon unloading, including a furnace wall, an adjustment structure connected to the furnace outlet on the furnace wall, the adjustment structure including a U-shaped adjustment frame corresponding to the furnace outlet, an adjustment plate corresponding to itself above the adjustment frame, a push-pull rod connected to the adjustment plate below the adjustment plate through a first wedge, and a second wedge corresponding to the first wedge movably connected to the push-pull rod.
[0006] Preferably, the opening of the adjustment frame is integrally connected to two conical blocks on both sides, with the side of the smaller opening of the conical block pointing towards the adjustment frame, and the adjustment plate is provided with a through hole corresponding to the width of the larger opening of the conical block.
[0007] Preferably, the adjusting plate is made of heat-insulating material, and a groove is provided on one side of the inner side of the adjusting plate. A tension spring is provided inside the groove, and a limiting rod corresponding to the inner diameter of the groove and fixedly connected to the tension spring is provided on the side of the adjusting plate away from the groove.
[0008] Preferably, a movable groove surrounding the adjustment frame is fixedly connected to the outer surface of the furnace wall, and the friction between the movable groove and the adjustment frame is less than the friction between the first wedge and the second wedge.
[0009] Preferably, the push-pull rod is provided with a T-shaped sliding groove with a length greater than that of the second wedge. A pair of blocking plates corresponding to the sliding groove are fixedly connected below the second wedge. The push-pull rod first drives the adjusting plate to slide together, and then pulls the second wedge to move and lift the first wedge.
[0010] Preferably, the adjustment plate is connected to corresponding sealing shells above it, and sealing strips are provided between the sealing shells and between the limiting rod and the groove.
[0011] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0012] This invention utilizes a push-pull rod to adjust the positions of the first and second wedges, thereby changing the height and spacing between the adjusting plates. When the adjusting plates are placed inside the furnace, they are tightly fitted together in a sealed connection. Pulling the push-pull rod initially allows the adjusting plates to move as a whole, thanks to the significant friction between the first and second wedges. When the push-pull rod presses against the second wedge, further pulling the rod causes the first wedge to contact the second wedge, raising the adjusting plates. The shape of the conical blocks on the adjusting frame alters the spacing between the adjusting plates. A limit rod ensures smooth movement, and a tension spring ensures the adjusting plates can return to their original position when the push-pull rod is pushed back.
[0013] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0024] like Figure 1 and Figure 2As shown, a furnace outlet structure for efficient and intelligent industrial silicon unloading includes a furnace wall 1. The furnace wall 1 is characterized by an adjustment structure 3 connected to an outlet 2. The adjustment structure 3 includes a U-shaped adjustment frame 4 corresponding to the outlet 2. An adjustment plate 5 corresponding to the adjustment frame 4 is located above the adjustment frame 4. A push-pull rod 7 is connected below the adjustment plate 5 via a first wedge 6. A second wedge 8 corresponding to the first wedge 6 is movably connected to the push-pull rod 7. Conical blocks 9 are integrally connected to both sides of the opening of the adjustment frame 4. The side with the smaller opening of the conical block 9 points towards the adjustment frame 4. The adjustment plate 5 has a through hole 10 corresponding to the width of the larger opening of the conical block 9. The adjustment plate 5 is made of heat-insulating material. A groove 11 is provided on one side of the interior of the adjustment plate 5. A tension spring 12 is located inside the groove 11. A limiting rod 13 corresponding to the inner diameter of the groove 11 and fixedly connected to the tension spring 12 is located on the side of the adjustment plate 5 away from the groove 11.
[0025] In this implementation scheme, the relative positions of the first wedge 6 and the second wedge 8 are adjusted by the extension and retraction of the push-pull rod 7, thereby changing the height and spacing of the adjusting plate 5. When the push-pull rod 7 moves the second wedge 8, the friction between the second wedge 8 and the first wedge 6 causes the adjusting plate 5 to move as a whole until the adjusting plates 5 are tightly pressed together, achieving a sealed connection. When the push-pull rod 7 is pulled further to press against the second wedge 8, it will cause the first wedge 6 to disengage from the second wedge 8 and lift the adjusting plate 5. The conical block 9 on the adjusting frame 4 guides the movement of the adjusting plate 5, changing the spacing between the adjusting plates 5. The limiting rod 13 ensures that the adjusting plate 5 moves smoothly, and the tension spring 12 provides a restoring force when the push-pull rod 7 is pushed back, ensuring that the adjusting plate 5 is accurately reset. This structure effectively enhances the sealing performance of the furnace outlet, prevents gas leakage inside the furnace, and improves the safety and stability of the production environment. At the same time, the use of heat insulation materials and reasonable design improve the heat preservation effect, reduce heat loss, improve energy utilization efficiency, reduce production costs, stabilize the furnace temperature, and ensure the quality and production efficiency of industrial silicon.
[0026] like Figure 3 , 4 As shown in Figure 5, a movable groove 14 surrounding the adjusting frame 4 is fixedly connected to the outer surface of the furnace wall 1. The friction between the movable groove 14 and the adjusting frame 4 is less than the friction between the first wedge 6 and the second wedge 8. The push-pull rod 7 is provided with a T-shaped sliding groove 15 with a length greater than that of the second wedge 8. A pair of blocking plates 16 corresponding to the sliding groove 15 are fixedly connected below the second wedge 8. The push-pull rod 7 first drives the adjusting plate 5 to slide together, and then pulls the second wedge 8 to move and lift the first wedge 6. Corresponding sealing shells 17 are respectively connected above the adjusting plate 5. Sealing strips 18 are provided between the sealing shells 17 and between the limiting rod 13 and the groove 11.
[0027] In this embodiment, the moving groove 14 is made of high-strength alloy steel with a smooth inner wall and precision machining to ensure low-friction fit with the adjusting frame 4. The adjusting frame 4 has a U-shaped structure and is made of high-temperature resistant cast iron. The conical blocks 9 integrated on both sides of the opening are made of the same material, with the smaller opening side pointing towards the adjusting frame 4 and matching the through hole 10 on the adjusting plate 5. The push-pull rod 7 is made of solid round steel with a hardened surface to improve durability and strength. The sliding groove 15 on the push-pull rod 7 is T-shaped and longer than the second wedge 8 to ensure sufficient movement space during pushing and pulling. The blocking plate 16 is fixedly connected below the second wedge 8, corresponding to the sliding groove 15, and is made of high-strength alloy steel to provide stable blocking. The adjusting plate 5 is made of heat-insulating material, with a groove 11 on one side inside. A tension spring 12 is installed in the groove 11, and the limiting rod 13 corresponds to the inner diameter of the groove 11 and is fixedly connected to the tension spring 12 to ensure smooth movement and accurate reset of the adjusting plate 5. The sealing shell 17 is made of high-temperature resistant alloy steel and is tightly connected to the adjusting plate 5. The sealing strip 18 between them is made of rubber at approximately 65 degrees, which has good elasticity and sealing performance. This structural design ensures smooth operation and reliable sealing of the furnace outlet during adjustment, effectively preventing heat loss and gas leakage, and improving the efficiency and quality of industrial silicon production.
[0028] In use, this device adjusts the relative positions of the first and second wedges by extending and retracting the push-pull rod, thereby changing the height and spacing of the adjusting plates. When the adjusting plate needs to be placed inside the furnace, the push-pull rod moves the second wedge. Utilizing the greater friction between the second and first wedges, the adjusting plate moves into the furnace as a whole until the plates are tightly pressed together, achieving a sealed connection. When the push-pull rod continues to pull, pressing against the second wedge, it causes the first wedge to disengage from the second wedge, lifting the adjusting plate. Simultaneously, the conical block on the adjusting frame guides the movement of the adjusting plate, changing the spacing between them. The limit rod ensures the stability of the adjusting plate during movement, while the tension spring provides a restoring force when the push-pull rod is pushed back, ensuring the adjusting plate accurately returns to its original position.
[0029] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
