Agitator device for smelting optical glass

Abstract

The invention provides an agitator device for smelting optical glass. The agitator device comprises spiral blade paddles, a blade paddle main rod, a straight-form rotary shaft, a cross fixing head, acooling water pipe and a torque sensor; the spiral blade paddles are arranged at the bottom end of the blade paddle main rod; the cross fixing head is arranged at the top of the blade paddle main rod;one end of the straight-form rotary shaft is crosswise connected with the blade paddle main rod through the cross fixing head; the torque sensor is arranged at the top end of the straight-form rotaryshaft; the straight-form rotary shaft has a structure of hollow pipe; the cooling water pipe is formed inside the straight-form rotary shaft; and cooling water enters the straight-form rotary shaft from the cooling water pipe. According to the agitator device, through the improvement of the agitator structure, the torque can be measured, the viscosity of glass can be very accurately characterized, the viscosity change of the glass is tracked, and finally the empirical correlation of the viscosity and the torque of the glass can be found through the quantization of data. The agitator has a very important effect on the adjustment of the production process.

Description

technical field [0001] The invention relates to the field of optical glass stirrers, in particular to a stirrer device for melting optical glass. Background technique [0002] The optical glass stirrer is an important component in the optical glass melting process. Its function is to form a uniform glass liquid from a variety of inhomogeneous raw materials, and the homogenization process is mainly completed by the glass stirrer through diffusion and convection. At present, the research on the homogenization function of the glass stirrer is relatively thorough, but it cannot reflect the viscosity of the glass liquid itself. The glass liquid will show different viscosities at different stages and different temperatures, so the glass viscosity is an important basis for judging the glass melting state. At present, the viscosity of the glass melting process can be measured by a high-temperature glass viscometer. However, due to the need for fast operation and high temperature on...

AI Technical Summary

Problems solved by technology

At present, the viscosity of the glass melting process can be measured by a high-temperature glass viscometer. However, due to the need for fast operation and high temperature on site, the detection operation is very inconvenient. Therefore, the on-site measurement method is mainly based on manual picking and experience.

However, this detection method is unreliable and relies too much on experience. Therefore, a glass melting device is needed to quickly and conveniently determine the instant viscosity of glass liquid, and at the same time, it needs to be easy to operate.
