Description

Bubbling agitation tank

The utility model relates to a bubbling agitation tank which is applied to a front end of a clarification operation of a glass liquid. In particular, the present invention relates to a bubbling agitation tank which uses a stirring blade to stir a glass liquid in advance to stir a gas contained in the glass liquid to form a bubble.

The well-known flat glass manufacturing method is to make the molten glass melt, refine, stir, cool, and adjust the temperature gradient to produce uniform and stable quality. For the glass, please refer to "Figure 1". The figure shows the schematic diagram of the clarification action of the glass in the clarification tube. As shown in the figure, a glass material is melted before being melted in a furnace. The molten glass is sent to a clarification tube 10 for clarification. After the molten glass is melted, the initially molten glass contains a large amount of small bubbles and gas (such as air). When the glass liquid is clarified, the bubbles will rise to the surface of the glass liquid and escape. However, there is still gas dissolved in the glass liquid in the glass liquid. Therefore, the glass solution is still not completely completed during the clarification process. Full clarification, so that the flat glass produced may contain air bubbles. Furthermore, the volume of bubbles formed by the molten glass in the clarification tube is small, and for the minute bubbles, the convection of the glass liquid can cause the movement of the small bubbles, and it is almost impossible to float upward to the surface of the glass to escape. Therefore, how to completely remove the gas contained in the glass liquid and further shorten the time required for the clarification operation is a problem to be solved.

In view of the above problems, the creator is based on years of experience in related industries and product design, research and analysis on glass conveying clarification operations, and can design better glass clarification equipment; The main object is to provide a bubbling agitation tank which can effectively remove a gas which is difficult to be clarified in a molten glass and which is effectively and completely removed during a clarification operation.

In order to achieve the above purpose, the bubbling stirring tank of the present invention is mainly composed of a stirring tank and a stirring rod, and is disposed at the front end of the glass liquid clarification operation, which is a pre-clarified molten state. The glass liquid is injected into the stirring tank and stirred by the stirring rod, so that the gas dissolved in the glass liquid is stirred to form a plurality of small bubbles, and then connected into a large bubble, so as to quickly float to the surface of the molten glass. Thereby, the effect of rapidly removing the gas which is difficult to completely clarify in the molten glass can be achieved.

In this embodiment, a rectangle is taken as an example, and is not limited thereto in other embodiments.

Please refer to "Fig. 3", which is a schematic diagram of the implementation of the creation (1). As shown in the figure, a glass material is melted by a furnace 21 at a high temperature, and melted into a molten glass. Through a feeding pipe 41 through the inlet port 2012 into the agitation tank 201; in addition, the glass liquid initially entering the agitation tank 201 still contains gas.

Please refer to "Fig. 4", which is a schematic diagram of the implementation of the creation (2). As shown in the figure, when the molten glass liquid enters the agitation tank 201, the stirring rod 202 is subjected to a driving device (not shown in this figure). The driving device is exemplified as a motor, and the driving device can be exemplified by a motor, and one end of the stirring bar 202 can be driven to be driven by the motor, but any one of the driving rods 202 can be driven to generate a rotating motion. The device can be implemented without limitation. In addition, when the stirring rod 202 is rotated, the stirring blades 2021 are also synchronously driven by the stirring rod 202 to make the glass in the stirring tank 201. The liquid is disturbed by the stirring blade 2021, and the molten glass is rotated and stirred in the stirring tank 201. During the tumbling process, the fine bubbles which are covered by the glass liquid or are still melted in the glass liquid, and the substances which have not been converted into a gaseous state are The plurality of small bubbles B1 are formed due to the change of the internal pressure of the stirring tank 201; in this embodiment, the inlet port 2012 can be placed at the top, and the discharge port 2013 can be placed at the bottom.
