A kind of high-efficiency drying equipment for quartz sand for optical lens production

Abstract

The invention discloses a high-efficiency drying equipment for quartz sand for optical lens production, comprising an outer box, a heating box, a hot air heater, a fan and a filter, as well as a disturbance device. The disturbance device includes a sliding rod and an electromagnet. The drying cloth is sealed. The beneficial effect of this equipment is that the quartz sand falls on the elastic drying cloth for drying, and the air in the fan drives the equipment to circulate. When passing through the filter position, the air is filtered and the water vapor in it is absorbed. When passing through the position of the hot air heater, the air is heated, and the hot air is disturbed by the disturbing device, which makes the elastic drying cloth vibrate, thus avoiding the accumulation of quartz sand during the drying process, making the drying more comprehensive and efficient, and at the same time disturbing The device can not only realize the shaking of the elastic drying cloth, but also realize the effect of discharging.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a high-efficiency drying device for quartz sand used for the production of optical lenses. Background technique [0002] Optical glass is made of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides mixed according to a specific formula, melted at high temperature in a platinum crucible, stirred evenly with ultrasonic waves to remove air bubbles; Slowly cool down over time to avoid internal stress on the glass block. After cooling, the glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. The qualified glass block is heated and forged. Optical lens blanks. [0003] Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof ma...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, drying is generally carried out by flowing hot air, resulting in that the heat during drying cannot be recycled, and during the drying process, due to the accumulation of sand bodies, it is difficult to pass hot air into the sand body, resulting in The drying is not comprehensive enough, which also reduces the drying efficiency
