Description

Technical Field

[0001] This utility model relates to the field of industrial silicon processing and production technology, and in particular to a closed-loop cooling device for industrial silicon. Background Technology

[0002] Industrial silicon, also known as crystalline silicon or metallic silicon, is primarily used as an additive in non-ferrous alloys. It is a product smelted from quartz and coke in an electric furnace. The main component, silicon, contains approximately 98% silicon, with the remaining impurities being iron, aluminum, calcium, etc. In the production of industrial silicon, quartz and coke are heated in a submerged arc furnace, then refined. After refining, the industrial silicon is cast, and then rapidly cooled to form silicon ingots.

[0003] However, most current cooling methods use air cooling, natural cooling, or spraying onto the surface of the mold, which result in poor cooling effect and low efficiency. Utility Model Content

[0004] The purpose of this application is to provide a closed-loop cooling device for industrial silicon to solve the problems of poor cooling effect and low cooling efficiency of existing cooling methods.

[0011] In a preferred embodiment, a closed cooling device for industrial silicon is provided with a screw-on nut at the outer end of the threaded rod.

[0012] In a preferred embodiment, a closed cooling device for industrial silicon is provided, wherein the sides of the bearing tank are provided with placement openings, and the push plate is located in the placement openings.

A hydraulic cylinder 4 is fixedly mounted on the horizontal mounting plate 3. The structure and working principle of the hydraulic cylinder 4 can be determined according to actual conditions. A connecting shaft 5 is fixed to the lower end of the hydraulic cylinder 4, and a bearing plate 6 is fixed to the lower end of the connecting shaft 5. A bearing groove 7 is provided on the bearing plate 6, and the bottom of the bearing groove 7 is mesh-like. In use, a mold containing industrial silicon needs to be placed into the bearing groove 7. Threaded rods 8 are screwed onto opposite positions on both sides of the bearing plate 6. After installation, one end of the threaded rod 8 extends into the bearing groove 7, and a push plate 9 is rotatably mounted on one end of the threaded rod 8. In use, the threaded rod 8 can be screwed to move the push plate 9 to abut against the outside of the mold to limit and fix the mold. The setting of the threaded rod 8 should be such that it does not affect the smooth downward movement of the bearing plate 6 into the cooling tank 1. A sealing cover 10 is fixed on the connecting shaft 5. The sealing cover 10 corresponds to the opening of the cooling box 1. The hydraulic cylinder 4 can drive the bearing plate 6 and the sealing cover 10 to move downward, so that the mold is submerged in water inside the cooling box 1. Cold water passes through the mesh at the bottom of the bearing groove 7 to cool the mold, and the sealing cover 10 covers the opening of the cooling box 1 to improve the cooling effect.

[0023] An exhaust pipe 11 is provided on the sealing cover 10, which is connected to a steam treatment device. During the cooling process, the generated steam can be discharged to the steam treatment device for treatment through the exhaust pipe 11. The steam treatment device is not shown in the figure. The sealing cover 10 prevents the generated water vapor from spreading everywhere. A spray plate is provided on the lower side of the sealing cover 10, and a water supply pipe 13 connected to the spray plate is provided on the upper side of the sealing cover 10. During the cooling process, cold water can be supplied to the spray plate through the water supply pipe 13, and the cold water is sprayed directly onto the upper surface of the mold through the spray plate, further improving the cooling effect and efficiency. In this embodiment, in actual operation, a drain pipe 12 needs to be provided on one side of the bottom of the cooling tank 1 to prevent the water in the cooling tank 1 from overflowing.

[0024] Example 2

[0025] Based on Example 1, a closed-loop cooling device for industrial silicon is provided. In order to save water, a circulation pump 15 is preferably installed on one side of the cooling tank 1 via a circulation hose 14. The other end of the circulation hose 14 is connected to the water supply pipe 13. When in use, the circulation pump 15 can be started to pump the water in the cooling tank 1 back to the water supply pipe 13 via the circulation hose 14, and spray it out through the spray plate to cool the mold located in the cooling tank 1.

[0026] Based on Example 1, in order to improve the movement stability of the support plate 6, a closed cooling device for industrial silicon is preferably provided with a limiting plate 16 on the upper side of the cooling box 1. The inner side of the limiting plate 16 is provided with a limiting groove 17 extending to the bottom of the cooling box 1. Correspondingly, a limiting block 18 is fixed at one end of the support plate 6. The limiting block 18 is located in the limiting groove 17. During the movement of the support plate 6, the limiting groove 17 and the limiting block 18 cooperate to limit the support plate 6.

The upper end of the spring 20 is fixedly connected to the lower side of the limiting block 18. During the downward movement of the support plate 6, the spring 20 is in a compressed state. The arrangement of the spring 20 and the support column 19 is required to ensure that the mold on the support plate 6 can be completely immersed in the water in the cooling box 1.

[0028] Based on Example 1, in order to facilitate the screwing operation of the threaded rod 8, a screwing nut 21 is preferably provided at the outer end of the threaded rod 8. In use, the screwing nut 21 can be clamped with a tool to screw the threaded rod 8.

[0029] Based on Example 1, in order to avoid the pusher plate 9 occupying the space of the support groove 7, a closed cooling device for industrial silicon is preferably provided with placement notches 22 on both sides of the support groove 7, so that the pusher plate 9 is located in the placement notches 22 when not in use.

[0030] This utility model provides a closed-loop cooling device for industrial silicon, including a cooling box 1. A vertical support plate 2 is fixed to one side of the cooling box 1, and a horizontal mounting plate 3 is fixed to the top of the vertical support plate 2. A hydraulic cylinder 4 is fixed on the horizontal mounting plate 3, and a bearing plate 6 is fixed to the lower end of the hydraulic cylinder 4 through a connecting shaft 5.

Threaded rods 8 extending into the bearing groove 7 are screwed onto opposite positions on both sides of the bearing plate 6. A push plate 9 that abuts against the outside of the mold is rotatably installed at one end of the threaded rod 8. Twisting the threaded rod 8 can move the push plate 9 to abut against the two sides of the mold to limit and fix the mold. A sealing cover 10 corresponding to the opening of the cooling box 1 is fixed on the connecting shaft 5. An exhaust pipe 11 is provided on the sealing cover 10 and is connected to a steam treatment device.

During the cooling process, the generated steam can be discharged to the steam treatment equipment through exhaust pipe 11 for treatment. A spray plate is provided on the lower side of the sealing cover 10, and a water supply pipe 13 connected to the spray plate is provided on the upper side of the sealing cover 10. At the same time, during the cooling process, cold water can be supplied to the spray plate through the water supply pipe 13, so that the cold water is sprayed directly onto the upper surface of the mold, further improving the cooling effect and efficiency.
