Description
the technical field is as follows:
The utility model belongs to the technical field of glass production technique and specifically relates to a glass platinum passageway clarification device.
Background art:
in the glass melting process, the physical dissolved gas in the glass melt and the micro bubbles mixed in the glass melt need to be completely discharged out of the glass melt to obtain high-quality glass, and the process is the clarification of the glass. In the existing glass clarification method of the platinum channel, gas discharge is accelerated by reducing viscosity of molten glass at high temperature, and gas release is accelerated by matching with a clarifier to discharge bubbles (the clarifier releases bubbles to form small bubbles in a glass melt in the floating process, the small bubbles are fused to form larger bubbles, the discharge speed of the larger bubbles is higher, and thus the clarification purpose is realized).
But the TFT-LCD glass has high-temperature viscosity, so that the required clarification temperature is higher, and the service life of the platinum channel body is influenced. And the addition of the clarifying agent can also increase the impurity content in the molten glass and reduce the quality of the molten glass.
The utility model has the following contents:
The utility model provides a clarification device for a glass platinum channel, aiming at overcoming the defects in the prior art.
the utility model provides a following technical scheme:
A clarifying device for a glass platinum channel comprises a platinum channel, wherein the platinum channel is a tubular channel made of refractory materials, a platinum layer covers the inner wall of the channel, each functional section of the platinum channel is heated in a manner that power supplies are communicated with the platinum layers at two ends of a heating functional section, so that the platinum layers in each section form an electric heater, or the refractory materials outside the functional sections are directly heated, molten glass in each section is heated or regulated through heat conduction, the platinum channel comprises a heating section, a clarifying section and a cooling section which are sequentially connected, the heating section is distributed in an inclined manner, the upper end of the heating section is communicated with the clarifying section which is horizontally distributed, the other end of the clarifying section is communicated with a cooling section, the diameter of the cooling section is smaller than that of the clarifying section, an exhaust pipe is communicated with the top of the clarifying section close to the cooling section, and a group of air sources with the diameter of 0.1 ~ 0.2.2 mm is arranged at the bottom of the clarifying section at the joint of the heating section and the clarifying section, one end of each air hole is communicated with an air pipe, and one end of the air pipe which extends out of the platinum channel is not communicated with a graph.

Utility model advantage: the utility model discloses have simple structure, convenient to use, reduced the input of clarifier among the prior art, if the good clarifier of avoiding using of control, improved the exhaust efficiency of glass liquid, consequently, need not to keep higher state with the temperature of platinum passageway to the life of platinum passageway has been improved.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
as shown in figure 1, the glass platinum channel clarifying device comprises a platinum channel, wherein the platinum channel is a tubular channel made of refractory materials, and the inner wall of the channel is covered with a platinum layer. The specific structure of the platinum channel is prior art and will not be described herein in detail.
The platinum channel comprises a heating section 1, a clarification section 2 and a cooling section 3 which are sequentially connected, wherein the heating section 1 is obliquely distributed, and the clarification section 2 which is horizontally distributed is communicated with the upper end of the heating section 1. And power supplies are communicated with the platinum layers at the two ends of each functional section, so that the platinum layers in each section form an electric heater, the glass metal flowing through each section is heated or regulated in temperature, the glass metal in each section is ensured to smoothly flow through each functional section, and the function of each section is realized.
the diameter of the clarification section 2 is larger than that of the heating section 1, so that a cavity 2a is formed between the liquid level 9 of the molten glass flowing into the clarification section 2 and the inner wall of the top of the clarification section 2. One end of the clarification section 2 is communicated with a cooling section 3 with the diameter smaller than that of the clarification section 2, and the cooling section 3 is positioned below the liquid level 9 of the molten glass so as to avoid gas from entering the cooling section 3.
The top of the clarification section 2 close to one side of the cooling section 3 is communicated with an exhaust pipe 4, so that the molten glass enters the clarification section 2 from the heating section and flows through enough travel, bubbles in the molten glass have enough time to be separated out of the surface of the molten glass upwards, and the molten glass is discharged through the exhaust pipe 4.
A group of air holes with the diameter of 0.1 ~ 0.2.2 mm are arranged at the bottom of the clarification section at one side of the clarification section 2 at the joint of the heating section 1 and the clarification section 2, the lower end of each air hole is communicated with one air pipe 5, the lower end of each air pipe 5 is communicated with the same gas distributor 6, so that the air pipes are distributed in a parallel state through the gas distributors, and the gas distributors 6 are communicated with air supply pipes 7 communicated with an air source, so that air provided by the air source is uniformly distributed to each air pipe by the gas distributors, and then enters the clarification section 2 from the air holes, bubbles with the diameter of 0.3mm-1mm can be formed in molten glass, and other tiny bubbles in the molten glass can be fused and taken out of the molten glass in the process of floating in the molten glass, and the molten glass can not enter the air holes due to the surface tension effect of the molten glass even under the condition of not supplying air.
The air supply pipe 7 and the air pipe 5 are both made of metal materials, the air supply pipe 7 is further sleeved with a corresponding matched electric heating device 8, and the electric heating device 8 is connected and matched with the air supply pipe 7 in a welding mode. The gas temperature fed through the gas supply tube 7 is set to 1620 ℃ to 1650 ℃ by heating the gas supply tube 7, which is higher than the temperature of the molten glass itself in the fining section 2, so that no heat loss is caused to the fining section. The gas is sent into the trachea through gas distributor, and gas distributor plays the steady voltage effect for the equal stability of gas pressure and the flow that gets into every trachea.
the gas supply pipe 7 is provided with a gas flow rate regulating valve and a gas temperature detecting device, which are not shown in the figure, and the gas flow rate entering the fining section 2 can be regulated at any time according to the glass metal flow rate flowing into the fining section 2. Ensuring that the gas flow entering the clarification section 2 is 1-5% of the volume flow of the molten glass in the clarification section 2.
