Description of the drawings:

fig. 1 is a schematic structural view of the present invention.

The specific implementation mode is as follows:

as shown in figure 1, the sealing observation device for the platinum channel glass liquid level comprises a stirring barrel 1, wherein the stirring barrel 1 comprises a barrel body 1c and a barrel cover 2 which is correspondingly covered and matched with the barrel cover at the upper opening end of the stirring barrel, a platinum layer 1b covers the inner wall of the barrel body 1c, and glass liquid 1a is arranged in the barrel body 1 c. A gas space is formed between the molten glass 1a and the barrel cover 2.

The inner wall of the barrel body 1c is provided with a first cavity 3 and a second cavity 4 which are longitudinally distributed, the barrel cover 2 is provided with through holes 9 which are vertically distributed, and the through holes 9 downwards penetrate through the second cavity 4, so that the first cavity 3 and the second cavity 4 are mutually communicated.

A first through hole 5 and a second through hole 6 which are communicated with the space in the stirring barrel 1 are arranged on one side of the first cavity 3. The first through hole 5 is positioned below the liquid level of the molten glass 1a, so that the molten glass 1a can flow into the first cavity 3, and the second through hole 6 is positioned above the liquid level of the molten glass 1a, so that the air pressure in the first cavity 3 is the same as the air pressure in the stirring barrel 1, and the liquid level in the first cavity 3 is the same as the liquid level in the stirring barrel 1.

A hollow buoy 7 is arranged in the first cavity 3, mark rods 8 which are vertically distributed are arranged on the buoy 7, the upper end of each mark rod 8 penetrates through the through hole 9, and the end part of each mark rod extends out of the barrel cover 2. And height scales 11 which are vertically distributed are arranged on the upper surface of the barrel cover 2.

The diameter of the marker post 8 is smaller than that of the through hole 9, the horizontal gap between the outer wall of the marker post 8 and the inner wall of the through hole 9 is smaller than 3mm, a sealing layer 10 is arranged in the second cavity 4, and a sealing medium of the sealing layer 10 is glass liquid formed after glass cullet is melted.

When the gap is smaller than 3mm, the glass liquid can not leak under the action of the surface tension of the glass liquid. By utilizing the property of the glass liquid, the glass liquid is selected as the sealing liquid, and the gap between the mark post 8 and the through hole 9 is controlled in the range of the leakage-free gap, so that the movement, the sealing and the leakage-free can be realized.

In order to adapt to the high-temperature use environment, the buoy 7 and the mark post 8 are both made of platinum materials. And because the horizontal direction of the second cavity 4 is not big with the inner wall of the stirring barrel 1, the cullet placed in the second cavity can effectively absorb the high temperature in the stirring barrel and be melted into molten glass, and the temperature (more than or equal to 1050 ℃) of the molten glass which is not hardened can be maintained so as to play a role in sealing. Like this, the scale contrast change on 8 tops of sighting rod and the altitude scale 11 is observed in the control room accessible video monitoring, can confirm the glass liquid level height in the agitator 1 in real time to this has improved the artifical observation condition.
