Description

Technical Field

[0001] The utility model relates to the technical field of fused quartz sand, in particular to a fused quartz magnetic separation device. Background Art

[0002] Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral. It is an important industrial mineral raw material, widely used in industries such as glass, casting, ceramics, refractory materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, and abrasives. However, in existing technologies, the quality of quartz products made from hot-melted quartz sand is seriously affected by the presence of elemental impurities and fluid impurities.

[0003] Fused quartz is an amorphous (glassy) form of silicon oxide (quartz, silica). It is a typical glass with a long-range disordered atomic structure. Its high operating temperature and low thermal expansion coefficient are achieved through cross-linking in its three-dimensional structure. Fused quartz melts at approximately 1713°C, has low thermal conductivity, and has one of the lowest thermal expansion coefficients of any refractory material, resulting in extremely high thermal shock resistance. Consequently, fused quartz mold shells rarely crack due to temperature fluctuations during firing and pouring, making it an ideal refractory for investment casting. It can be used as a refractory for topcoats or backcoats, as well as a material for sanding. Fused quartz can partially or completely improve mold performance. Its low thermal expansion coefficient helps prevent cracking and deformation during the dewaxing and firing processes, ensuring dimensional stability in the casting. Fused quartz's high purity ensures excellent coating stability and improves the mold shell's high-temperature creep resistance.

[0004] Currently, when processing quartz on the market, magnetic separation and screening are usually performed on the fused quartz after crushing. However, the fixed-position magnetic separation mechanism can only exert a certain suction force on particles of a fixed size, thereby separating the fixed-size fused quartz. Since the crushing process of the fused quartz produces quartz sand of different particle sizes, the versatility of the separation process is low and it cannot meet the requirements of magnetic separation and screening of particles of different sizes. Therefore, a fused quartz magnetic separation device is proposed. Utility Model Content
