Problems solved by technology
[0002] In recent years, with the continuous improvement of the functional requirements of high-end electronic devices and the advancement of science, it is required that the applied glass materials need to be of extremely high purity and cannot introduce unexpected elements and unexpected foreign matter impurities, but the traditional melting glass pool furnace It is made of refractory materials. These refractory materials are in direct contact with the glass solution when the solute glass is used. After the glass becomes liquid, impurities will be mixed into it, which will reduce the purity of the glass.
And the bottom of the pool wall of the existing technical kind is all made of refractory materials coated with corrosion-resistant rare precious metals such as platinum and rhodium. Under the high temperature of the glass solution, the refractory materials outside the cladding layer will release some of their own elements to poison rare and precious metals such as platinum and rhodium, thereby shortening the service life of rare and precious metals such as platinum and rhodium, and greatly increasing the manufacturing cost

Embodiment Construction
[0023] figure 1 Described is the solute glass pool furnace of the present invention, comprising a chest cavity 2, a dome 1 is provided at the upper end of the chest cavity 2, and a cavity for melting glass made of corrosion-resistant metal is provided at the lower end of the chest cavity 2. There are cooling channels inside. The cavity of the molten glass includes a pool wall 3 and a pool bottom 4. In a specific embodiment, the pool wall 3 and the pool bottom 4 can be integrally formed, or the pool wall 3 and the pool bottom 4 are separately arranged, and are specifically implemented below. The example will relate to the embodiment in which the pool wall 3 and the pool bottom 4 are arranged separately. In a specific embodiment, the cross-sectional shape of the pool wall can be circular or polygonal, and at the same time, the bottom of the pool matches with the different cross-sectional shapes.

The invention discloses a tank furnace for melting glass. The tank furnace comprises a thoracic cavity (2), an upper end of which is provided with a crown (1) and a lower end of which is equipped with a cavity which is prepared from a corrosion-resistant heatproof metal material and is used for melting glass. The corrosion-resistant heatproof metal material for preparing the cavity is a stainless steel material. A cooling channel is disposed inside the wall of the cavity. The cavity for melting glass comprises a tank wall (3) and a tank bottom (4). The internal side of the tank bottom (4) and that of the tank wall (3) are provided with a cooling channel. A liquid coolant influx and a liquid coolant outflux are arranged on both the tank bottom (4) and the tank wall (3). The influx communicates with the outflux through the cooling channel.
