Description
Technical field:
the invention relates to the field of float glass production equipment, in particular to a tin bath coating device.
The background technology is as follows:
the forming of float glass is accomplished in a tin bath. Molten glass continuously flows into a tin bath from a melting furnace, floats on the surface of the molten glass, spreads and levels on the molten glass under the action of gravity and surface tension to form a glass belt with flat upper and lower surfaces, and the flat glass product is obtained after annealing, cooling and cutting. The float glass production requires that the tin bath has good air tightness, in order to prevent oxidation of tin liquid in the tin bath from polluting glass, the space in the tin bath needs to be filled with reducing gas, usually mixed gas of nitrogen and hydrogen, and meanwhile, the oxygen content in the tin bath is required to be small, and when the tin bath is not sealed well, such as an operation hole is opened, air can leak in, so that the operation frequency of the operation hole is reduced as much as possible for preventing air leakage.
In-line coating is performed during the manufacturing process of float glass, usually in a tin bath or an annealing furnace, by spraying coating gas onto the surface of the formed glass ribbon, the gas undergoes a chemical reaction on the surface of the hot glass sheet, the reaction product is deposited on the surface of the glass to form a thin film, the device for spraying the coating gas is called a coating device, when coating is performed in the tin bath, the coating device in the prior art is inserted into the tin bath from the side wall of the tin bath, the coating device spans over the glass ribbon, and the coating gas is sprayed out from the lower opening of the coating device.
The tin bath is a structure surrounded by a top cover, side walls and a pool bottom, the top cover, the side walls and the pool bottom are all fixed, the float glass process requires a certain space distance from the top cover to the glass belt, generally 300-800 mm, a film plating device in the prior art is transversely inserted in the space, and the lower bottom surface of the film plating device is required to be close to the upper surface of the glass belt in the film plating process.
In order to enable the film plating device to enter and exit the tin bath, a rectangular hole which is penetrated in pairs is required to be formed in the side wall of the tin bath, the film plating device enters the tin bath from one side hole and penetrates out from the other side hole, two ends of the film plating device are supported on the outer side of the tin bath, the size of the rectangular hole is generally 1500-2500 mm, and the height of the rectangular hole is 200-700 mm.
The prior coating technology has the defects that the sealing of a tin bath is damaged: 1) When the film plating production is to be carried out, rectangular holes on two sides are opened, air enters the tin bath in the process of penetrating the film plating device into the tin bath, so that tin liquid is oxidized, glass is polluted, the loss of the tin liquid is increased, the tin bath dissipates heat, the energy consumption is increased, meanwhile, the process stability of the tin bath is disturbed, the recovery can be carried out only for a certain time, and the production loss is large; 2) When the plating production is finished, the plating device is pulled out of the tin bath to resume the float glass production, and the tin bath seal is destroyed again in the process; 3) Products of the chemical reaction are not only deposited on the glass plate, but also deposited in the gas pipeline, the gas pipeline needs to be cleaned after a plurality of glass factories continuously coat films for 6-40 hours at present, and as the pipeline is positioned in the film coating device, the whole film coating device needs to be pulled out of the tin bath to be cleaned and then is inserted back into the tin bath, so that film coating production is recovered, frequent sealing damage is caused by frequent cleaning, and the production loss is huge; 4) Although the gap between the coater and the rectangular opening is plugged with a thermal insulation cotton plug after the coater is in place, it is difficult to ensure a thorough seal. In addition, because the temperature in the tin bath is higher, in order to protect the steel structure of the film plating device, the film plating device is also provided with water cooling, the water cooling can cool the glass belt, and the low temperature of the glass belt is unfavorable for film growth.
The invention comprises the following steps:
the invention provides a tin bath coating device for overcoming the defects in the prior art.
The invention provides the following technical scheme:
the utility model provides a tin bath coating film device, it includes fixed top cap, its characterized in that: the fixed top cover is provided with an opening, a movable top cover which is correspondingly matched with the opening is arranged, the groove body is provided with at least one air inlet hole and at least one air outlet hole, the air inlet hole is internally provided with an air inlet pipe, the air outlet hole is internally provided with an air outlet pipe, and the movable top cover is provided with a pair of hanging rings which are correspondingly matched with the lifting device.
On the basis of the technical scheme, the following further technical scheme is also available:

Valves are also arranged on the air inlet pipe and the air outlet pipe.
Sealing rings which are correspondingly matched with the movable top cover are sleeved on the air inlet pipe and the air outlet pipe.
And sealing blocks which are correspondingly matched with the movable top covers are arranged on the top covers at the two sides of the movable top cover. The invention has the advantages that:
1) The device does not need to open large-area operation holes on the side walls or the top covers of the tin bath, and in the production switching process of float glass and coated glass, the movable top covers are closely clung to the adjacent fixed top covers to lift, the gap between the movable top covers is small, and the sealing bricks are used for auxiliary sealing, so that the continuity and the stability of the sealing state of the tin bath are effectively ensured;
2) The pipeline is easy to clean, and the air pipe is cleaned or replaced when the air pipe is blocked, so that the damage to the tin bath seal in the cleaning process is reduced to the greatest extent;
3) The glass ribbon is not cooled by a water cooling structure, so that the growth of the film is facilitated.
