Description

Technical Field

[0001] This application relates to the field of cooling devices, and more specifically, to a high-efficiency cooling device for silicon powder production. Background Technology

[0002] During the production of silicon powder, cooling devices are required for cooling operations. The common method is to transport silicon powder into a spiral pipe and use cooling water to cool the outside of the pipe. The pipe transfers the temperature of the silicon powder inside to the cooling water, thereby cooling the silicon powder. However, when the diameter of the spiral pipe is small, silicon powder can easily clog the spiral pipe. Once a blockage occurs, it needs to be cleared, which is time-consuming and laborious. On the other hand, a larger diameter spiral pipe directly leads to poor cooling effect. Utility Model Content

[0023] The working principle of this high-efficiency cooling device for silicon powder production is as follows: The produced silicon powder is injected into the hopper 210. The feeding screw cylinder 220 conveys the silicon powder inside the hopper 210. Simultaneously, during this conveying process, the silicon powder passes through the feeding screw cylinder 220 and sequentially enters the upper part of multiple cooling screw cylinders 230. The cooling screw cylinders 230 are spaced apart, and their pipe diameters are relatively smaller than those of the feeding screw cylinder 220. The output end of the motor 250 drives the discharge screw cylinder 240 to rotate, which in turn drives the feeding screw cylinder 220 to rotate. The discharge screw cylinder 240 then drives the cooling screw cylinders 230 to rotate. Therefore, when the silicon powder reaches the cooling screw cylinders... After reaching the top of the vertical spiral cylinder 230, the silicon powder is conveyed by the cooling spiral cylinder 230 to the discharge spiral cylinder 240. During the conveying process, rapid cooling also occurs. Upon reaching the discharge spiral cylinder 240, the silicon powder is cooled again. Therefore, in the entire process, the produced silicon powder is first conveyed to the feeding spiral cylinder 220 for initial cooling, then enters the cooling spiral cylinder 230 for secondary rapid cooling, and finally enters the discharge spiral cylinder 240 for final cooling. The entire conveying process uses a spiral cylinder guiding method, which achieves rapid and effective cooling while avoiding clogging problems.
