Description

TECHNICAL FIELD

[0001] The application relates to the technical field of quartz sand purification furnaces, for example to a quartz sand chlorination purification furnace discharging mechanism. BACKGROUND

[0002] Quartz sand chlorination purification is an effective method for removing impurities in quartz sand through high-temperature chlorination reaction. The method utilizes the chemical reaction between the chlorinating agent and the impurities in the quartz sand at high temperature to generate volatile chlorides, thereby removing the impurities through gas phase or solid-liquid separation to improve the purity of the quartz sand.

[0003] The conventional technology for quartz sand chlorination purification is to place the quartz sand raw material inside a material pipe, which is in an inclined state. As the material pipe slowly rotates, the raw material will slowly slide from one end to the other end by gravity. The material pipe is inserted into a designated heating box, and the quartz sand raw material will be heated by the heating box during the sliding process in the material pipe to generate volatile chlorides with the chlorinating agent, achieving the purpose of removing impurities. After the quartz sand raw material is purified, it needs to be discharged from the material pipe to proceed to the next process. In the prior art, a conical structure with a hole is provided at the end of the material pipe, and then the quartz sand raw material is guided out through the hole. However, this way of closing the end of the material pipe and discharging through the hole is prone to sand accumulation when discharging the quartz sand raw material, which affects the production efficiency.
