Problems solved by technology

The single-crucible device is generally composed of a stirrer 2, a crucible 1 and a discharge pipe 3. The mother-child single-crucible melting device is only different in the shape of the stepped crucible 4 and the crucible 1 and the number of the stirrer 2, such as figure 1 , figure 2 As shown, these two production devices have three disadvantages: one is that due to the single-crucible melting, the quality of each crucible product will be affected by different operations and produce optical fluctuations, which will affect the yield rate of glass; After a period of time, due to the difference in expansion rate between platinum and refractory materials, deep wrinkles appear on the bottom of the platinum crucible, and the uneven bottom of the crucible usually makes it difficult to stir the molten glass evenly when stirring or ventilating, thus affecting the uniformity of the prepared glass; It is due to the long smelting time of each crucible when the device is preparing materials, resulting in limited smelting capacity

Embodiment 1

[0018] Such as image 3 As shown, the special-shaped crucible of the present invention adopts a boot-shaped crucible 5, and the cross-section of the boot-shaped crucible 5 is a semicircle sealed with an arc or a polygon sealed with an arc.

[0019] Wherein the polygonal cross section is a semicircle, rectangle or other shapes. The left dividing plate 7, the middle dividing plate 9, and the right dividing plate 11 divide the whole crucible into three parts: the melting chamber 14, the homogenizing chamber 15 and the discharge chamber 16, and the three parts are connected. When the raw material is continuously added into the melting chamber 14 from the feeding pipe 6, the molten glass flows into the discharging chamber 16 through the homogenizing chamber 15 curve after the raw material is melted, and continuously flows out from the discharging pipe 3. Due to the effect of the three partitions, the flow distance of the glass is lengthened, which is better than the traditional si...

Embodiment 2

[0023] Such as Figure 4 As shown, the special-shaped crucible of the present invention adopts a trapezoidal crucible 12, and the cross section of the trapezoidal crucible 12 is trapezoidal, and its feeding pipe, left, right and middle partition plates, ventilation pipes, air vents and the arrangement of the feeding pipe are the same as in the embodiment 1.

Embodiment 3

[0025] Such as Figure 5 Shown, special-shaped crucible of the present invention adopts polygonal crucible 13, and the cross-section of polygonal crucible 13 is polygonal shape, and its feeding pipe, left, right and middle dividing plate, ventilation pipe, venting hole and the same implementation with discharging pipe arrangement mode example 1.

[0026] The part of the smelting device of the present invention in contact with molten glass is preferably made of pure platinum or zirconium-strengthened platinum material or platinum alloy.

[0027] Ventilation pipe 8 of the present invention can adopt multiple modes, as straight pipe, connect bubbler etc. under straight pipe.

[0028] Give two examples of producing optical glass with the device of the present invention below.

Abstract

The invention relates to a platinum device for optical glass feed preparation and belongs to the technical field of a feed preparation furnace for continuous smelting in a tank furnace. The platinum device mainly solves the problems that a conventional single crucible generates optical property fluctuation, influences uniformity and has limited smelting capacity. The platinum device is mainly characterized in that the crucible is a boot-shaped crucible; a left division plate and a right division plate are arranged at the inner bottom of the crucible at intervals and are used for dividing the inner bottom of the crucible into a material melting chamber, a homogenization chamber and a discharging chamber which are communicated; a discharging pipe is arranged at the bottom of the discharging chamber; a feeding pipe is arranged on the upper port of the material melting chamber of the crucible, and the port of the feeding pipe is higher than the upper flat surface of the crucible; and a breather pipe, a middle division plate and an air-bleed hole are arranged on the crucible above the homogenization chamber. The platinum device has the characteristics that the continuous smelting process can be realized, the glass smelting capacity and efficiency under the same volume can be effectively improved, the product is uniform, and the yield is high; and the platinum device is used for a continuous platinum smelting device for optical glass feed preparation.

Description

technical field [0001] The invention belongs to the technical field of material preparation furnaces for continuous smelting of pool furnaces, and relates to a platinum device for material preparation of optical glass, in particular to a continuous platinum smelting device for material preparation of optical glass. It can not only improve the melting efficiency of single-crucible glass with the same volume, but also achieve uninterrupted melting effect, especially suitable for the material preparation process in the optical glass melting process. Background technique [0002] With the fierce competition and development of the optoelectronic product market, manufacturing optical components at low cost is the goal of every optical material and optical component manufacturer. At present, there are two main ways to manufacture optical glass: continuous melting in pool furnace and single crucible production. The continuous melting of the pool furnace has the advantages of large ...
