Calcining device for purifying quartz sand

Abstract

The invention discloses a calcining device for purifying quartz sand. The calcining device for purifying the quartz sand comprises a shell, wherein a crucible is fixedly installed in the shell; a heat preservation layer is arranged on the outer side of the crucible; a first partition plate is arranged at the bottom of the heat preservation layer; an air suction pump is fixedly installed on one side of the bottom of the first partition plate; an electric heater is fixedly installed on the side, away from the air suction pump, of the bottom of the first partition plate; a second partition plate is fixedly installed at the top of the heat preservation layer; a motor is fixedly installed on one side of the top of the second partition plate; an output shaft of the motor is connected with a conveying screw rod; a smashing box is arranged at the bottom, close to the other end of the conveying screw rod, of the second partition plate; smashing blades are fixedly installed on one side in the smashing box; a first filter screen is arranged at the position, close to the bottoms of the smashing blades, in the smashing box; and a second filter screen is fixedly installed in the second partition plate. The calcining device for purifying the quartz sand is simple and reasonable in structure, effectively solves the problem that most existing calcining devices for purifying the quartz sand are lack of controlling the granularity of the quartz sand, and has wide popularization and application values.

Description

technical field [0001] The invention relates to the technical field of quartz sand purification, in particular to a calcining device for purifying quartz sand. Background technique [0002] High-purity silica is an extremely important optoelectronic material and is widely used in high-tech fields such as semiconductors, optical fiber communication, lasers, and aerospace. With the rapid development of these fields, the requirements for impurity content in high-purity silica are more stringent, and the demand for high-purity silica is also increasing. At present, most of the high-purity silica required in my country relies on imports. Therefore, the use of quartz sand purification technology to obtain high-purity silica is an effective way to meet the demand for high-purity silicon in my country's high-tech field, and is of great significance to promoting the development of my country's national economy. [0003] In the process of purifying quartz sand, in order to remove th...
