Problems solved by technology

[0004] In the prior art, in the process of melting glass frit, bubbles will inevitably be generated. Bubbles are the most common and difficult defects in glass production, especially in crucible furnaces. Bubbles not only affect the transparency of glass In the field of glass deep processing, air bubbles are the key indicators to identify the quality of the original film, so how to eliminate the generated air bubbles has become an important problem in glass production

Embodiment approach

[0029] As a specific embodiment of the present invention, equidistant thorns 1111 are fixedly connected to the inner wall of the No. 1 through hole 111, and the thorns 1111 are arranged symmetrically. The steps from the outer cavity 12 to the inner cavity 11 decrease in sequence.

[0030] When the glass frit in the outer cavity 12 melts and enters the inner cavity 11 through the No. 1 through hole 111, the inner wall of the No. 1 through hole 111 is fixedly connected with equidistant thorns 1111. The thorns 1111 in the No. 1 through hole 111 will pierce the air bubbles, and The distance between the top of 1111 and the central axis of No. 1 through hole 111 gradually decreases from the outer cavity 12 to the inner cavity 11, which can pierce air bubbles of different sizes, further eliminate air bubbles, and improve the efficiency of air bubble elimination.

[0031] As a specific embodiment of the present invention, there is a No. 1 annular channel 122 on the left side of the wa...

Abstract

The invention relates to the technical field of glass smelting furnaces, in particular to an optical glass smelting furnace which comprises a smelting furnace body, a door body, a ball disc, a transmission shaft, a ball bearing, a sealing ring and a motor, the smelting furnace body comprises an inner cavity, an outer cavity and a heating cavity, the ball disc is arranged at the bottom end of the bottom wall of the inner cavity, and a through hole is formed in the middle of the ball disc. The top end of the transmission shaft penetrates through the through hole to be fixedly connected with the bottom wall of the inner cavity, the ball bearing is arranged on the outer surface of the transmission shaft, the sealing ring is arranged above the ball bearing and matched with the ball bearing to achieve the sealing effect, and a rotor on the motor and the bottom end of the transmission shaft are fixedly connected into a groove. Centrifugal force is generated through rotation of the inner cavity, and the effect of removing bubbles is achieved under the action of the centrifugal force.

Description

technical field [0001] The invention relates to the technical field of glass melting furnaces, in particular to an optical glass melting furnace. Background technique [0002] Glass is an amorphous inorganic non-metallic material with good transparency and chemical stability, and is widely used in daily life. Such as various glassware, tableware, cups, plates, plates and other glass daily necessities and decorations; exquisite art glass, vases, artificial glass gems; and extremely common light bulbs, lamp tubes, displays, etc. In addition, glass is often seen in architectural windows and the outer packaging of food and wine products. Our life is inseparable from glass, and the manufacture of glass is also inseparable from glass melting furnaces. [0003] The glass melting furnace is a special equipment for glass melting in the glass industry. It can also be used in the laboratories of ceramics, glass, enamel and other industries to prepare frits, glass low-temperature flux...
