Description

Technical Field

[0001] This utility model relates to the field of low bubble rate optical glass softening furnace technology, and more specifically to a low bubble rate optical glass softening furnace. Background Technology

[0002] Low-bubble-rate optical glass softening furnaces are key pieces of equipment designed specifically for producing high-quality optical glass. Their core function lies in precise temperature control and atmosphere management. The furnace is equipped with highly efficient heating elements and an insulation layer to ensure uniform softening of the glass raw material at a suitable temperature, while minimizing the intrusion of external gases. An advanced atmosphere control system can regulate the gas composition within the furnace, further suppressing bubble formation.

[0003] During operation, bubbles may have difficulty escaping from the molten glass, resulting in incomplete bubble removal. This affects the transparency and optical uniformity of the optical glass, reducing product quality. The softened material cools more slowly, giving bubbles more time and opportunity to form and grow within the glass, leading to an increased bubble content. The slow cooling process also causes uneven stress distribution within the glass, making it prone to cracking, deformation, and other problems.

[0004] Therefore, in order to solve the above problems, this application provides a low bubble rate optical glass softening furnace. Utility Model Content

[0025] The working principle of this utility model:

[0026] The device is placed horizontally above the ground. The operator then places the material to be softened into the mixing tank 201 through the feed inlet 202. The heating element 302 then activates, providing heat to the mixing tank 201 to promote material softening. Simultaneously, the drive motor 203 starts operating, and its output drives the second gear 209 to rotate. The rotation of the second gear 209, in turn, drives the meshing first gear 204 to rotate. The rotation of the first gear 204 then drives the transmission rod 205 and the mixing rod 206, which are fixedly mounted below, to rotate. The rotating action achieves the effect of stirring. During the stirring process, the operator adds clarifying agent into the mixing tank 201 through the feed inlet 202 to accelerate the removal of bubbles and ensure the consistency of the material. After softening, the vacuum pump 401 sucks the softened material from the mixing tank 201 into the molding chamber 403 through the feed pipe 402. At this time, the condenser pipe 502 starts to work, thereby accelerating the shaping of the material inside the molding chamber 403. After shaping is completed, the operator only needs to open the baffle 404 through the handle 406 to pull out the mold 407 from inside the molding chamber 403 to complete the work.
