Abstract
The invention discloses a connection manner of electrodes molten by a glass kiln. The electrode connection manner is characterized in that each pair of electrodes are connected in a cross wiring manner; and each pair of electrodes have a potential phase difference of 360 degrees. According to the invention, the electrode connection manner is optimized by improving the conventional electrode direct connection manner, thereby optimizing distribution of power line in molten glass, changing the flow direction of molten glass in the glass kiln, and changing the temperature distribution of molten glass in the glass kiln.
Description
Technical field
The invention belongs to the manufacturing field of TFT-LCD glass substrate, relate to the support equipment in glass furnace, especially for the electrode structure of the heating of glass furnace melting pool.
Background technology
In the liquid crystal glass base processing procedure, the kiln dissolving tank is the equipment that glass is melted.Liquid-crystalline glasses belongs to borosilicate glass, its feed composition decision, and this glass metal needs higher melting temperature (Tm).The temperature of flame meeting heating for dissolving pond top glass liquid, the glass metal bottom is because far away apart from flame space, and temperature is lower.The thermal conductivity of glass metal makes that with mobile relatively poor glass metal at the bottom of the dissolving tank pond keeps lower temperature and long residence time.This next step clarification to glass metal is unfavorable, and the long residence time can change the component of dissolving tank bottom glass liquid simultaneously.
Electric glass melting is that electric current is introduced in the glass metal through electrode, and the glass metal that energising back two electrodes are asked produces joule heating under the effect of alternating-current, thereby reaches fusing and thermoregulated purpose.Why glass metal has electroconductibility, and the glass intermediate ion that mainly is based under the liquid state moves under the driving of electrical forces.1902, the Wal gram was got permission a basic patent, and its content is that utilization is to the regulation and control of ionic state electric current, by the preparing glass charge heat effect molten glass that ionic current produces under mixes liquid.Along with the updating and develop of furnace design for glass electric melting and electrode, this electricity fusing-aid method is used widely.
The advantage of the electricity fusing-aid heating technique of glass furnace is:
1), improves melting rate significantly.Melting rate can improve 60%, even 100%.
2), improve the refining quality of glass.Under any circumstance adopt electricity fusing-aid can both improve the quality of glass.This is to have improved because strengthened the mobile homogeneity of glass metal that makes of glass metal.
3), flexible load.The tank furnace that adopts electricity fusing-aid to heat can be regulated the load of tank furnace according to market demand rapidly.
4), the electricity fusing-aid device is particularly useful for high melting glass.TFT-LCD glass is high-boron-silicon glass, belongs to a kind of of high melting glass.After being arranged in the electrifying electrodes of pool wall, the glass metal that is in molten state is a conductor.According to the heat effect principle of resistance, two interelectrode glass metals will generate heat.Simultaneously, because the fringing effect of electrode tip, near the temperature of glass liquid the electrode tip is the highest, here temperature even can reach more than 1700 ℃.Because the difference of proportion has just formed the glass flow near electrode, the glass of dark each layer of direction in pond has all fully been participated in this and has been flowed, thereby has eliminated the problem that the high-boron-silicon glass layering is brought.In addition, electrode tip " heat release " phenomenon in glass metal and the glass flow that produces have therefrom improved the temperature of bottom glass metal, have accelerated the dissolution rate of quartz particles, have promoted the clarification and homogenization of glass.
The mode of connection of the electrode of the electricity fusing-aid heating technique of existing glass kiln is the mode of being connected in series, and this mode of connection makes the electric force lines distribution in the glass metal inhomogeneous, and the electrically heated proportion is little, and the fusing effect is relatively poor etc.
Summary of the invention
The structure that the purpose of this invention is to provide a kind of glass furnace consumable electrode; Through mode of connection and the current potential phase differential that changes every counter electrode; Design through rational electrically heated loop; Make the power line uniform distribution in the glass metal, increase the electrically heated proportion simultaneously, make it to reach the effect of mixed melting.
The present invention for realizing the technical scheme that goal of the invention adopts is:
A kind of electrode structure of glass furnace melting pool comprises the glass furnace melting pool, and is arranged on the counter electrode on the glass furnace melting pool, connects with the staggered mode of connection between said every counter electrode.
Be that first counter electrode the right electrode is connected with the second counter electrode left side electrode with the staggered mode of connection between said every counter electrode; Second counter electrode the right electrode is connected with the 3rd counter electrode left side electrode; The 3rd counter electrode the right electrode is connected with the 4th counter electrode left side electrode; By that analogy, N-1 counter electrode the right electrode is connected with N counter electrode left side electrode, and N counter electrode the right electrode n1 is connected with the first counter electrode left side electrode.
The current potential phase differential is 360 degree between said every counter electrode.
This electrode connection mode connects every counter electrode with the mode of connection of intersecting, and the current potential phase differential is 360 degree between every counter electrode.The direct-connected electrode mode of this electrode pair tradition is transformed, and the counter electrode mode of connection is optimized, and has optimized the distribution of power line in glass metal, has changed the flow direction of glass metal in thawing furnace, has changed the temperature distribution of glass metal in thawing furnace.
