Description

Technical Field

[0001] The utility model relates to the technical field of silicon micropowder production equipment, in particular to a purification device for silicon micropowder production. Background Art

[0002] Silica powder is a non-toxic, odorless, pollution-free inorganic non-metallic material. It has excellent properties such as good temperature resistance, acid and alkali corrosion resistance, high thermal conductivity, high insulation, low expansion, stable chemical properties, and high hardness. Silica powder is made of natural quartz (SiO2) or fused quartz (amorphous SiO2 after natural quartz is melted at high temperature and cooled) through multiple processes such as crushing, ball milling (or vibration, air flow milling), flotation, acid washing purification, and high-purity water treatment. Among them, flotation purification is a method of separating useful minerals and impurities based on the different physical and chemical properties of the surface of mineral particles. The surface of the particles themselves has hydrophobicity or the hydrophobicity is generated or enhanced by the action of flotation agents. The mineral particles after process treatment can be affinity with bubbles and flotation agents and float on the surface of the ore liquid of the flotation equipment, thereby realizing impurity separation.

[0003] The utility model patent with announcement number CN217017000U is named as a purification device for silicon micropowder production, including a purification tank, which is composed of a purification tank body and a liftable sleeve, the liftable sleeve is mounted on the upper part of the purification tank, and the liftable sleeve and the purification tank are clearance-matched, a connecting rod mechanism is arranged below the liftable sleeve, the connecting rod mechanism is composed of a first connecting rod and a second connecting rod, the upper end of the second connecting rod is rotatably connected to the liftable sleeve through a rotating shaft, the lower end of the second connecting rod is connected to one end of the first connecting rod through a rotating shaft, and the other end of the first connecting rod is fixedly connected to the power output shaft of the motor. It can be seen from the scheme in combination with the claims, the specification and the drawings that the scheme mainly drives the connecting rod mechanism to rotate through a motor, and the connecting rod mechanism drives the liftable sleeve to slide up and down along the surface of the purification tank body. When the liftable sleeve slides to the lowest end, since the top surface of the liftable sleeve is lower than the top surface of the purification tank body, the foam floating inside the purification tank body will flow out naturally, thereby achieving the purpose of quickly eliminating the foam on the liquid surface, which is not only efficient but also has good impurity removal efficiency. Therefore, it can be clearly known that the lifting sleeve needs to be slid to the lowest end, and the foam is removed in a natural outflowing manner. Although this method can remove the foam, the amount of water used to remove the foam is difficult to control, and the amount of water used will increase, which will cause a waste of water resources and increase the manufacturer's cost to a certain extent. Therefore, a purification device for silicon micropowder production is now proposed. Utility Model Content
