Efficient quartz sand drying equipment for optical lens production

Abstract

The invention discloses efficient quartz sand drying equipment for optical lens production, which comprises an outer box body, a heating box, an air heater, a fan and a filter, and further comprises adisturbance device, the disturbance device comprises a sliding rod and an electromagnet, and the heating box is sealed by elastic drying cloth. The equipment has the following beneficial effects thatquartz sand falls on the elastic drying cloth for drying, the fan drives air in the equipment to circulate and pass through the position of the filter, the air is filtered, water vapor in the air isabsorbed, and when the air passes through the position of the air heater, the air is heated, and the hot air is disturbed through the disturbance device, so that the elastic drying cloth shakes, accumulation of the quartz sand is avoided in the drying process, and drying is more comprehensive and efficient; and meanwhile, the disturbance device not only can realize the shaking of the elastic drying cloth, but also can realize the discharging effect.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to high-efficiency drying equipment for quartz sand used in the production of optical lenses. Background technique [0002] Optical glass is mixed with oxides of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melted at high temperature in a platinum crucible, stirred evenly with ultrasonic waves, and removed air bubbles; Slowly cool down over time to avoid internal stress in the glass block. The cooled glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to form 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 materi...

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
