Description

Technical Field

[0001] The utility model relates to the technical field of fused quartz sand, in particular to a quartz fused impurity removal and purification device. Background Art

[0002] Quartz sand is a silicate mineral with hardness, wear resistance and stable chemical properties. It is an important industrial mineral raw material and is widely used in glass, casting, ceramics and refractory materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. In the prior art, the quartz products made from quartz sand after hot melting have elemental impurities and fluid impurities, which seriously affect the quality of the quartz products.

[0003] Fused quartz is an amorphous (glassy) state of silicon oxide (quartz, silica). It is a typical glass with a long-range disordered atomic structure. It provides high operating temperature and low thermal expansion coefficient through three-dimensional structural cross-linking. The melting temperature of fused quartz is about 1713℃, the thermal conductivity is low, and the thermal expansion coefficient is almost the smallest among all refractory materials, so it has extremely high thermal shock stability. Therefore, during the roasting and pouring process, the fused quartz shell rarely breaks due to temperature changes. It is an ideal refractory material for investment casting. It can be used as a refractory material for surface or back layer coating, as well as a sanding material. Fused quartz will partially or fully improve the performance of the shell. The small thermal expansion coefficient of fused quartz is conducive to preventing the shell from cracking and deformation during the dewaxing and roasting process, and is conducive to ensuring the dimensional stability of the casting. Fused quartz has high purity and good stability of the coating; the high temperature creep resistance of the shell is improved.

[0004] At present, the market mostly uses magnetic separators to remove internal impurities for molten quartz sand purification, but traditional magnetic separators are prone to material accumulation during operation, and the magnetic separation working area is small, which seriously affects the efficiency of molten quartz sand purification, reduces the production of molten quartz sand, and brings inconvenience to the purification and processing of molten quartz sand. Therefore, a quartz molten impurity removal and purification device is proposed. Utility Model Content
