Abstract
The utility model relates to a glass runner sealing device, it includes glass runner (1) and molten tin bath (2), is equipped with flashboard (3) on glass runner (1), is equipped with zero shellfish of molten tin bath (2 a) its characterized in that on glass runner (1) between flashboard (3) and molten tin bath (2): be equipped with bridge brick (7) between flashboard (3) and molten tin bath zero shellfish (2 a), bridge brick (7) lower extreme inserts in glass runner (1) and corresponds the cooperation with flashboard (3). The utility model discloses simple structure, manufacturing are simple and convenient, and the gas in the effectual reduction molten tin bath of ability is from molten tin bath import regulating gate board gap end around and is escaped.
Description
The technical field is as follows:
the utility model belongs to the technical field of float glass production facility and specifically relates to a glass runner sealing device.
Background art: when the float forming process is adopted to produce glass, molten tin must be used as a float medium, but the molten tin is extremely easy to oxidize when meeting oxygen, in order to prevent the oxidation of the molten tin, a certain amount of protective gas (N2 + H2) needs to be introduced into the molten tin, a certain pressure is formed in the molten tin to prevent external oxygen from entering, and the purpose of reducing oxides is achieved at the same time. The existence of tin oxide greatly increases the volatilization amount of tin liquid, particularly the tin steam amount in a high-temperature area of a tin bath, so that when tin bath gas escapes from a gap end around an inlet adjusting flashboard of the tin bath, the tin steam is contacted with oxygen to generate solid tin dioxide at high temperature to condense around the adjusting flashboard, and the solid tin dioxide drops on a glass plate along with the increase of deposition amount or the up-and-down movement of the flashboard to form a cassiterite defect.
The utility model has the following contents:
the utility model provides a glass flow passage sealing device for overcoming the defects in the prior art.
The application provides the following technical scheme:
the utility model provides a glass runner sealing device, it includes glass runner and molten tin bath, is equipped with the flashboard on the glass runner, is equipped with zero shellfish of molten tin bath its characterized in that on the glass runner between flashboard and molten tin bath: and a gap bridge brick is arranged between the flashboard and the zero shell of the molten tin bath, and the lower end of the gap bridge brick is inserted into the glass flow channel and correspondingly matched with the flashboard.
On the basis of the technical scheme, the following further technical scheme can be provided:
the gap bridge brick is provided with two lap gaps which are correspondingly matched with the walls of the launders, so that the gap bridge brick is integrally of a T-shaped structure, the top end of the gap bridge brick is provided with a bayonet with a tin bath zero shell corresponding to the matching, and the lower end of the gap bridge brick is also downwards extended with two sealing parts which are correspondingly matched with the flashboards.
Utility model advantage:
the utility model discloses simple structure, manufacturing are simple and convenient, and the gas in the effectual reduction molten tin bath of ability is from molten tin bath import regulating gate board gap end around and is escaped.
Description of the drawings:
fig. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic structural view of the bridge brick of fig. 1.
The specific implementation mode is as follows:
as shown in fig. 1 and 2, a glass flow path sealing device includes a glass flow path 1, a tin bath zero point 2a and a tin bath 2 connected in sequence.
The glass runner 1 is provided with the flashboard 3, the upper end of the flashboard 3 is connected and matched with the existing lifting device, the lower end of the flashboard 3 is inserted into the glass runner 1 and correspondingly matched with the molten glass 6, and the flow of the molten glass 6 in the glass runner 1 entering the molten tin bath 2 is controlled by the lifting flashboard 3. The lifting device is prior art and is not described in detail here.
And a gap bridge brick 7 is bridged on the runner side wall brick between the flashboard 3 and the molten tin bath shell 2 a. The gap bridge brick 7 is manufactured by processing refractory bricks and comprises an upper cross beam 7c bridged on the side wall brick of the runner, and one side of the cross beam 7c is provided with a bayonet 7b correspondingly matched with the tin bath shell 2 a. An extension part 7d extending into the glass flow channel 1 downwards is arranged in the middle of the bottom of the cross beam 7c, gaps between two sides of the extension part 7d and the side wall bricks of the flow channel are smaller than 2mm, and the distance between the bottom surface of the extension part 7d and the bottom brick 1a of the glass flow channel 1 is 150-200 mm. And lap joint notches 7a which are correspondingly matched with the end parts of the top ends of the side wall bricks of the flow channel are formed on the two sides of the extension part 7d and the bottom surface of the cross beam 7 c.
Two sealing parts 7c corresponding to gaps between the gate plate 3 and the runner sidewall bricks extend downwards from the bottom of the extension part 7d, and a certain distance is reserved between the two sealing parts 7 c. The width of the sealing part 7c is 100-200 mm, and the distance between the lower end of the sealing part and the liquid level of the molten glass is 10-20 mm.
The protective gas containing tin steam in the tin bath is well controlled to penetrate out of contact surfaces of the two sides of the flashboard and the side wall of the flow channel by adding the bridging brick 7, the escape resistance of a zero-shell interface of the flashboard and the tin bath is improved, and a good sealing effect is achieved.
