Detailed Description
As shown in fig. 3-4, the all-electric melting device for producing optical glass of the present invention comprises an upper side wall 2, an electrode 3, a lower side wall 4 and a hearth bottom 5, wherein the upper side wall 2, the lower side wall 4 and the hearth bottom 5 are combined to form a hearth 7 with a T-shaped longitudinal section, as shown in fig. 3, which is completely different from the existing straight structure.
The cross sections of the upper side wall 2, the lower side wall 4 and the hearth bottom 5 are in a 4-M-edge structure, wherein M is an integer larger than 4, and a 6-edge structure is shown in FIG. 4. 1-n layers of 1-M electrodes 3 are arranged on the 2-M-2 edges of the 4-M polygonal structure of the upper side wall 2, wherein n is an integer larger than 1, M is an integer larger than 1, so as to ensure the temperature field distribution and high temperature requirement of the hearth 7, the adjustable range of the process is wide, and fig. 4 shows that 2 layers of 2 electrodes 3 are arranged on the 3 edges. The electrode 3 heats the optical glass in the T-shaped structure hearth 7, and the highest temperature in the hearth 7 can reach 1200-1600 ℃.
The electrodes 3 may be installed horizontally or inclined downward by 1 to 60 degrees or inclined upward by 1 to 60 degrees, and fig. 3 shows horizontal installation. The electrode 3 may be a platinum electrode or a molybdenum electrode.
Above-mentioned 2 upper portions of last side wall are provided with charge door 1, form cold top structure, reinforced adoption cold top feeding mode, promptly: the powder material at the top of the furnace almost completely covers the surface of the molten glass to form a cold top, and the red molten glass cannot be seen.
And a liquid flowing hole 6 is formed at the joint of the lower side wall 4 and the hearth bottom 5, and the molten glass flows out through the liquid flowing hole 6 and enters the next working procedure until the glass is discharged and formed.
The device of the utility model well solves the problems of limited product specification, low yield, frequent maintenance, high production cost and the like in the optical glass production by the existing optical glass all-electric melting device.
