Furnace hole plugging device for industrial silicon furnace

Abstract

The invention discloses a furnace hole plugging device for an industrial silicon furnace. The furnace hole plugging device comprises a main machine base body, a spray plugging device, a continuous feeding device and a continuous furnace hole plugging device. The spray plugging device, the continuous feeding device and the continuous furnace hole plugging device are arranged on the main machine base body and connected with the main machine base body in a sliding manner. The spray plugging device, the continuous feeding device and the continuous furnace hole plugging device are controlled through an electric control system. By means of the spray plugging device, hole plugging particulate materials can be driven into a furnace hole of the industrial silicon furnace; by means of the continuous feeding device, the furnace hole plugging materials can be fed to the furnace hole; and by means of the continuous furnace hole plugging device, the furnace hole plugging materials can be pushed into the furnace hole and tamped. The furnace hole plugging device simulates the working procedure of manual furnace hole plugging and achieves flexibility of manual furnace hole plugging; all actions are controlled by the electric control system to be mechanically completed, the safety problem caused by manual operation is solved, the labor intensity is lowered, and the work efficiency is greatly improved; and the purpose of the high quality and stable yield can be achieved.

Description

technical field [0001] The invention relates to the technical field of equipment for opening and plugging holes of industrial silicon electric furnaces, in particular to a device for plugging holes of industrial silicon furnaces. Background technique [0002] After the industrial silicon electric furnace smelts the charge to a certain temperature, it needs to put the high-temperature liquid silicon water at about 1650-1800 ° C into the ladle by manually opening the furnace eye, and then go through the subsequent process and cast it into shape. At present, the method of plugging the furnace hole is a traditional purely manual operation, which usually requires the assistance of 4-5 people, and the working area is within 3-5 meters in the direction of the furnace hole, which is a high-risk, high-temperature, and high-dust area. High strength, low safety factor. [0003] Moreover, due to the high-purity characteristics of industrial silicon products, the temperature of liquid s...

Problems solved by technology

At present, the method of plugging the furnace hole is the traditional purely manual operation, which usually requires the assistance of 4-5 people, and the working area is within 3-5 meters in the direction of the furnace hole, which belongs to the high-risk, high-temperature, high-dust area. High strength, low safety factor

[0003] Moreover, due to the high-purity characteristics of industrial silicon products, the temperature of liquid silicon water is high, and the scouring damage to the furnace hole is great when it is released from the furnace; when the furnace hole is blocked, the parts of the tools used that contact high-temperature liquid silicon water must be resistant to high temperature and scouring , and it is strictly forbidden to be polluted by iron, so the tools for blocking the furnace hole must have better protective measures, or use high temperature resistant materials
