Description

Technical Field

[0001] The utility model belongs to the technical field of metal silicon cooling, and in particular relates to a cooling device for metal silicon production. Background Art

[0002] Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. When producing metallic silicon, quartz and coke are put into a submerged arc furnace for heating and then refined. After the metallic silicon is refined, it is poured. After pouring, it is quickly cooled to form a silicon ingot. When pouring liquid metallic silicon, due to its high temperature, the liquid silicon generates high temperature on the surface of the mold when it is poured into the mold, so it needs to be cooled.

[0003] After searching, the patent with application number 202321398496.3 discloses a cooling device for metallic silicon production. This patent can fix the mold by setting threaded rods and clamps. With the electric push rod and Hull slide rod, the mold can enter the cooling water tank for cooling. However, this method of fixing the mold requires frequent manual disassembly and installation, which is troublesome to operate and requires high labor costs. Moreover, by setting a reset spring on the inner side of the friction plate, although the clamp can have a certain fixing effect on the mold, this fixing method easily causes the mold to loosen after being fixed, and has poor stability. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a cooling device for the production of metallic silicon. By setting a metallic silicon mold clamping mechanism with a bidirectional threaded structure, the servo motor can drive the clamping plates to approach or move away at the same time, thereby realizing the clamping and loosening of the mold. This clamping method avoids the trouble of manually fixing the mold, reduces production costs, and avoids the loosening of the mold after being fixed by a reset spring, and has higher stability.

The hanging rod 801 is slidably connected to the hook plates 7. By setting an impurity collection frame 8 that can be detachably installed with the lifting frame 61, on the one hand, impurities generated during the cooling of metallic silicon can be collected. On the other hand, the trouble of manual cleaning caused by impurities falling into the water tank 1 can be avoided. The impurity collection frame 8 is highly practical.
