Abstract

The present invention provides a production device and method capable of reducing dripping on a borosilicate 3.3 float glass plate surface, and relates to the field of borosilicate 3.3 float glass plate surfaces. A production device capable of reducing dripping on a borosilicate 3.3 float glass plate surface comprises a tin bath steel shell, and a tin bath cover is fixedly connected to the upper surface of the tin bath steel shell. The present invention uses a triangular air-cooled air bag to condense high-silicon-oxygen substances in the protective gas when the protective gas crosses a partition wall after controlling the flow direction of the protective gas in the tin bath steel shell. When the protective gas crosses a partition wall, a part of the triangular air-cooled air bag that has collected volatiles is moved out of the tin bath steel shell through a lead screw, a central gear, an internal threaded sleeve rod, a planetary gear and a control motor, and the condensate is manually removed. Another part of the triangular air-cooled air bag enters the tin bath and then condenses the volatiles. This is repeated, so that the amount of condensed dripping formed by high-silicon-oxygen volatiles in the tin bath steel shell falling on the glass can be effectively reduced, and the production qualification rate of borosilicate glass can be improved.

Description

Technical Field

[0002] High borosilicate glass is a kind of glass with enhanced fire resistance. The manufacturing process involves adding glaze water glass sand, soda water and lime. Since the melting point of high borosilicate glass is higher than that of ordinary silicate glass, some new technologies and processes are needed in the manufacturing process.

[0003] Borosilicate glass is made by adding borosilicate sand, soda water and ground lime to the glaze of traditional glassmaking. Since borosilicate glass melts at a higher temperature than ordinary silicate glass, some new technologies are needed to enable industrial production.

[0004] When the temperature is high (1150℃), some components of high borosilicate glass will volatilize due to its own characteristics. When the volatile components reach a certain concentration in the protective gas of the tin bath, they will condense into "high-silicon oxide droplets" on the low-temperature surface of the tin bath. The droplets will gather on the brick surface above the tin bath and drip on the glass surface, causing dripping defects. This defect has a huge impact on the quality of the glass.

The production device for reducing dripping on the surface of borosilicate 3.3 float glass according to claim 1, characterized in that: The right side surface of the tin bath steel shell (1) and the right side surface of the sealing cover (3) are both fixedly connected with an outlet curtain (26), and the right side of the front side surface of the tin bath steel shell (1) is fixedly connected with an observation window (27).

7. The production device for reducing dripping on the surface of borosilicate 3.3 float glass according to claim 1, characterized in that: Two transition rollers (28) are rotatably connected to the right sides of the front and rear inner walls of the tin bath steel shell (1), and an N2 inlet (29) is fixedly connected to the right side of the upper surface of the tin bath cover (2).

8. A production method for reducing dripping on the surface of borosilicate 3.3 float glass, using the production device according to any one of claims 1 to 7, characterized in that: The specific steps are as follows: S1. The sealing cover (3) is divided into three areas under the action of the partition (4), and the aperture of the air inlet hole for entering the gas in the sealing cover (3) increases from left to right, so that the N2 and H2 mixed gases enter the device through the air inlet hole, and the air inlet holes take in 70%, 20%, and 10% of the gas from right to left, respectively, and the gas flows from right to left and is discharged through the exhaust hole (21). The blocked N2 air inlet hole (30) on the sealing box (16) is connected to the air inlet hole on the left side, so that the N2 and H2 mixed gases entering the triangular air-cooled air bag (5) through the N2 air inlet port (9) directly enter the sealing box (16) for accumulation after being discharged, and come out of the sealing box (16) to the air inlet hole on the left side to enter the inside of the device, and then are discharged through the exhaust hole (21); S2, the glass liquid is introduced into the tin bath steel shell (1) through the tin bath cover (2) and the lip brick (22), and the amount of the glass liquid entering is controlled by the flow valve (23). The glass liquid enters the tin bath steel shell (1) and adheres to the tin liquid (25). Under the flow of N2 and H2 mixed gas, the volatiles in the glass liquid are condensed on the triangular air cooling air bag (5). The formed glass is discharged through two transition rollers (28), and N2 gas is injected into the tin bath cover (2) through the N2 inlet (29) to filter the residue. After completion, the glass is discharged; S3. When the high-silicon-oxygen material on the triangular air-cooling air bag (5) is collected to a certain extent, the driving device is started, specifically: at this time, the control motor (15) is connected to an external power supply, and the control motor (15) is started, so that the control motor (15) drives one of the planetary gears (13) to rotate, thereby driving the central gear (12) on the internal threaded sleeve rod (11) to rotate, and drives the other planetary gears (13) to drive support, so that the lead screw (8) in the triangular air-cooling air bag (5) is rotated on the internal threaded sleeve rod (11 ), when the triangular air-cooling air bag (5) moves, the triangular opening (17) in the sealing box (16) limits the movement of the triangular air-cooling air bag (5), and the sealing gasket (18) maintains the sealing of the triangular air-cooling air bag (5) when it moves. The triangular air-cooling air bag (5) moves a part of the air bag that collects the volatiles out of the tin bath steel shell (1), and the condensate on the triangular air-cooling air bag (5) is manually removed, and the other part of the air bag enters the tin bath steel shell (1) to condense the volatiles.
