Embodiment Construction

[0023] Such as Figure 1~Figure 5 As shown, a melting tank of an optical glass furnace includes a cover brick 8, a wall brick 3 and a bottom brick 6, and the cover brick 8, wall brick 3 and bottom brick 6 form a hollow melting tank body from top to bottom. Cover brick 8, wall brick 3 and bottom brick 6 are all made of fused zirconia corundum bricks.

[0024] The melting pool of the present invention is square, with an area of ​​0.95-1.92 square meters and a depth of 0.78-0.98 meters. The upper part of the main body of the melting pool is provided with a material inlet 2 and the bottom is provided with a material outlet 13 . The bottom of the main body of the melting pool is provided with four bubblers 12 with a diameter of 8 mm. 3 burning guns 1 are distributed on the upper part of the melting pool, fuel: natural gas, liquefied gas, etc.

[0025] A plurality of temperature measuring holes 10 are arranged on the main body of the melting pool, and thermocouples are installed ...

Abstract

An optical glass kiln melting tank comprises cover bricks, wall bricks and bottom bricks which are arranged from top to bottom to form a hollow melting tank body. The melting tank body is provided with a feed inlet on the upper portion and a discharge outlet at the bottom. The bottom of the melting tank body is provided with a plurality of bubblers. A plurality of burning lances are disposed on the upper portion of the melting tank body. An upper tin electrode and a lower tin electrode are disposed in the melting tank body. A plurality of temperature measuring holes are formed in the melting tank body. A thermoelectric couple is mounted at each temperature measuring hole. A discharge hole is formed at the bottom of the melting tank body. The optical glass kiln melting tank has the advantages that melting capability of the melting tank is increased, daily yield of special glass is increased, production range of special glass is widened, process requirements of subsequent clarification and homogenization are lowered, energy is saved, and quality of special glass is improved.

Description

technical field [0001] The invention discloses a melting pool of an optical glass furnace, which is used for the production of multi-grade special glass. Background technique [0002] The existing glass furnace melting tank generally only adopts one of two heating methods, electric heating and electric fusion heating. It is rare to be able to meet both electric hybrid heating and electric fusion heating alone. For the production of special glass, the grades involved are complex, the glass formula system is wide, and the requirements for glass property parameters and internal quality are high. A single heating method cannot guarantee the quality of special glass. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a melting pool of an optical glass furnace, which can reduce energy consumption, meet the production needs of many special glass grades, and easily meet the technical requirements of clarification and homog...
