Description
Technical Field
[0001] This utility model belongs to the field of polysilicon production equipment manufacturing technology, and in particular relates to a silicon core support structure for an ultra-large reduction furnace. Background Technology
[0002] With the continuous growth of global demand for clean energy, the solar photovoltaic industry has developed rapidly. As a basic material for the photovoltaic industry, the market demand for polysilicon continues to expand. In order to meet the needs of large-scale polysilicon production, polysilicon manufacturers are constantly pursuing larger-scale and more efficient production equipment, and ultra-large reduction furnaces have emerged as a result.
[0003] The silicon core support structure of the ultra-large reduction furnace refers to a specific device or structure used to support the silicon core inside the ultra-large reduction furnace in polysilicon production, and is made of high-temperature resistant materials.
[0004] In existing equipment, silicon cores are usually quite thin and long. When working in the reduction furnace, they need to withstand their own weight and the force of airflow. If they are not clamped, the silicon cores may bend, deform or even break due to uneven stress, which may increase the silicon core processing cost. Therefore, we provide a silicon core support structure for an ultra-large reduction furnace. Utility Model Content
[0005] The purpose of this utility model is to provide a silicon core support structure for an ultra-large reduction furnace. Through the clamping mechanism and the protective mechanism, it solves the problem that in the existing equipment, since the silicon core is usually relatively thin and long, it needs to bear its own weight and the force of airflow when the reduction furnace is working. If it is not clamped, the silicon core may bend, deform or even break due to uneven force, which may increase the silicon core processing cost.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a silicon core support structure for an ultra-large reduction furnace, including a reduction furnace, the inner wall of which is provided with a plurality of heat dissipation holes, and the inner wall of the reduction furnace is provided with a clamping mechanism.
[0008] The clamping mechanism includes a motor plate, the outer wall of which is fixedly connected to the outer wall of the reduction furnace. A motor is fixedly connected to the inner wall of the motor plate. A controller is fixedly connected to the outer wall of the motor plate at the end away from the reduction furnace. A rotating shaft is fixedly connected to the bottom output shaft of the motor via a coupling. A pulley is fixedly connected to the outer wall of the rotating shaft. A belt is driven to the outer wall of the pulley. A second pulley is driven to the inner wall of the belt at the end away from the pulley. A second rotating shaft is rotatably connected to the inner wall of the second pulley. Threaded rods are fixedly connected to the outer walls of both the second rotating shaft and the rotating shaft.
[0009] Furthermore, the outer wall of the threaded rod is rotatably connected to the inner wall of the reduction furnace, and a threaded frame is threadedly connected to the outer wall of the threaded rod. Several rotating frames are rotatably connected to the inner wall of the end of the threaded frame away from the motor plate.
[0010] Furthermore, a clamping frame is rotatably connected to the outer wall of the rotating frame away from the threaded rod, and a rotating shaft is fixedly connected to the outer wall of the clamping frame near the motor plate. A protective mechanism is provided on the inner wall of the reduction furnace.
[0011] Furthermore, the protective mechanism includes several telescopic rods, the outer walls of which are fixedly connected to the inner wall of the reduction furnace, and springs are sleeved on the outer walls of the telescopic rods.
[0012] Furthermore, a heat insulation plate is fixedly connected to the outer wall of the end of the spring away from the motor plate, and the inner wall of the heat insulation plate is rotatably connected to the outer wall of the rotating shaft.
[0013] Furthermore, the inner wall of the reduction furnace is rotatably connected to a second rotating shaft, and the outer wall of the second rotating shaft is fixedly connected to a baffle, the outer wall of the baffle being slidably connected to the outer wall of the reduction furnace.
[0014] Furthermore, a support block is fixedly connected to the outer wall of the reduction furnace at the end away from the motor plate, and a telescopic rod is fixedly connected to the outer wall of the support block at the end near the reduction furnace.
[0015] Furthermore, a spring is sleeved on the outer wall of the telescopic rod two, and a locking rod is fixedly connected to the outer wall of the spring two near the reduction furnace. The outer wall of the locking rod is slidably connected to the inner wall of the baffle.
[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model, by setting up a clamping frame, first opens the reduction furnace, and uses the rotation of the rotating shaft and the second rotating shaft to rotate the threaded rods at both ends. The rotation of the threaded rods causes the threaded frame to move, and the movement of the threaded frame causes the clamping frames at both ends to retract inward. The rotation of the clamping frame clamps the material, achieving stable clamping of the material and preventing the silicon core from bending, deforming, or even breaking due to the need to withstand its own weight and the force of airflow.
[0018] 2. This utility model incorporates a clamping rod. When the material vibrates during processing, the telescopic rod and spring buffer the vibration. The spring retracts the clamping rod, causing it to move out of the baffle. Then, multiple heat dissipation holes cool the inside of the reduction furnace. This effectively buffers the vibration generated during material processing and cools the reduction furnace, preventing excessively high temperatures inside the furnace from affecting the material processing quality.
[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-5 As shown, this utility model is a silicon core support structure for an ultra-large reduction furnace, including a reduction furnace 1. The inner wall of the reduction furnace 1 is provided with a plurality of heat dissipation holes 101, and the inner wall of the reduction furnace 1 is provided with a clamping mechanism 2.
[0030] The clamping mechanism 2 includes a motor plate 201. The outer wall of the motor plate 201 is fixedly connected to the outer wall of the reduction furnace 1. A motor 202 is fixedly connected to the inner wall of the motor plate 201. The motor plate 201 fixes the position of the motor 202, preventing it from changing position during operation and causing damage. A controller 203 is fixedly connected to the outer wall of the end of the motor plate 201 away from the reduction furnace 1. A rotating shaft 204 is fixedly connected to the bottom output shaft of the motor 202 via a coupling. A pulley 205 is fixedly connected to the outer wall of the rotating shaft 204. A belt 206 is driven by the outer wall of the pulley 205. The rotation of the rotating shaft 204 drives the pulley 205 to rotate, preventing the pulley 205 from failing to rotate and causing the device to malfunction. A second pulley 207 is connected to the inner wall of the end away from the pulley 205. A second rotating shaft 208 is rotatably connected to the inner wall of the second pulley 207. Threaded rods 209 are fixedly connected to the outer walls of both the second rotating shaft 208 and the rotating shaft 204. The second rotating shaft 208 enables the threaded rod 209 to rotate stably, preventing it from falling off and damaging the device. The outer wall of the threaded rod 209 is rotatably connected to the inner wall of the reduction furnace 1. A threaded frame 210 is threadedly connected to the outer wall of the threaded rod 209. Several rotating frames 211 are rotatably connected to the inner wall of the threaded frame 210 away from the motor plate 201. The movement of the threaded frame 210 drives the rotating frames 211 to move stably, avoiding the problem of the rotating frames 211 being unable to move and causing the device to jam.
[0031] A clamping frame 212 is rotatably connected to the outer wall of the rotating frame 211 away from the threaded rod 209. A rotating shaft 213 is fixedly connected to the outer wall of the clamping frame 212 near the motor plate 201. A protective mechanism 3 is provided on the inner wall of the reduction furnace 1. The protective mechanism 3 includes several telescopic rods 301. The position of the telescopic rods 301 is fixed by the reduction furnace 1 to prevent the telescopic rods 301 from falling off during the operation of the device and affecting the normal use of the device. The outer wall of the several telescopic rods 301... The telescopic rod 301 is fixedly connected to the inner wall of the reduction furnace 1. A spring 302 is sleeved on the outer wall of the telescopic rod 301. A heat insulation plate 303 is fixedly connected to the outer wall of the end of the spring 302 away from the motor plate 201. The inner wall of the heat insulation plate 303 is rotatably connected to the outer wall of the rotating shaft 213. The inner wall of the heat insulation plate 303 is slidably connected to the outer wall of the threaded frame 210. The heat insulation plate 303 enables the rotating shaft 213 to rotate stably, avoiding the problem of the rotating shaft 213 flipping over when rotating, which would cause the device to jam.
[0032] A rotating shaft 304 is rotatably connected to the inner wall of the reduction furnace 1. A baffle 305 is fixedly connected to the outer wall of the rotating shaft 304. The outer wall of the baffle 305 is slidably connected to the outer wall of the reduction furnace 1. A support block 306 is fixedly connected to the outer wall of the end of the reduction furnace 1 away from the motor plate 201. The rotation of the rotating shaft 304 drives the baffle 305 to rotate stably, preventing the baffle 305 from falling off during rotation and affecting the normal operation of the device. A telescopic rod 307 is fixedly connected to the outer wall of the support block 306 near the reduction furnace 1. A spring 308 is sleeved on the outer wall of the telescopic rod 307. A locking rod 309 is fixedly connected to the outer wall of the spring 308 near the reduction furnace 1. The outer wall of the locking rod 309 is slidably connected to the inner wall of the baffle 305. The telescopic rod 307 and the spring 308 enable the locking rod 309 to move stably, preventing the locking rod 309 from deflecting during movement and causing the device to jam.
[0033] One specific application of this embodiment is:
[0034] When the operator needs to use the equipment, first open the reduction furnace 1, then place the end of the material in contact with the surface of one end of the clamping frame 212. Next, start the motor 202 via the controller 203. The motor 202 causes the rotating shaft 204 to rotate, which in turn drives the pulley 205 to rotate. The pulley 205 drives the belt 206 to rotate, which in turn drives the second pulley 207 to rotate. The second pulley 207 then drives the second rotating shaft 208 to rotate. The rotation of the rotating shafts 204 and 208 causes the threaded rods 209 at both ends to rotate. The rotation of the threaded rods 209 causes the threaded frame 210 to move, which in turn drives the rotating frame 211 to rotate. The rotating frame 211 then drives the clamping frame 212 to rotate stably via the rotating shaft 213. The movement of the threaded frame 210 drives the clamping frames 212 at both ends to rotate. 12 retracts inward, using the rotation of the clamping frame 212 to clamp the material. When the material vibrates during processing, the heat insulation plate 303 squeezes the telescopic rod 301 and spring 302, using the telescopic rod 301 and spring 302 to buffer the vibration generated during material processing, avoiding the material's vibration affecting its processing quality. When the internal temperature of the reduction furnace 1 is too high, the clamping rod 309 is pulled, causing the clamping rod 309 to squeeze the telescopic rod 307 and spring 308. The spring 308 causes the clamping rod 309 to retract and move it out of the baffle 305. Then, the baffle 305 is rotated by the rotating shaft 304, and the baffle 305 is no longer in contact with the reduction furnace 1. Then, the internal heat dissipation of the reduction furnace 1 is achieved through multiple heat dissipation holes 101.
