Problems solved by technology

When adding tin, it is necessary to open the sealed tin tank, which may lead to the intrusion of outside air. The tin block is directly put into the tin liquid, which will inevitably reduce the temperature of the tin liquid at the input port, resulting in process fluctuations

Embodiment 1

[0022] Such as figure 1 In the tin bath shown in the float glass forming process, a semicircular or arc-shaped tin bath edge 8 is arranged at the end of the tin bath outlet, and a diversion groove 9 is arranged outside the edge 8, and the diversion groove 9 passes through the The diversion pipe 5 is connected to the recovery tank 6 at the bottom, and the recovery tank 6 is connected to the tin bath through the circulation pump and the liquid supply pipe 7. The edge 8 is lower than the surface of the tin liquid 2, and the tin liquid 2 flows out along the edge through the diversion tank 9 And the guide pipe 5 flows into the bottom recovery tank 6, and then the tin liquid is sent from the liquid supply pipe 7 to the tank in front of the mouth 8 through the circulation pump to form a circulation.

[0023] The tin bath device includes tin bath bottom brick 1, transition roller 4, diversion pipe 5, recovery box 6, liquid supply pipe 7, glass plate 3 floats on the surface of tin liqu...

Embodiment 2

[0025] As a further optimized design of implementation example 1, a transition roller 4 is arranged behind the exit of the tin bath, and the installation height of the transition roller 4 is equal to the tin liquid level in the bath or 0-10mm lower than the tin liquid level, and the glass plate passes through the tin bath exit Finally, the glass plate is pulled out of the tin bath by the tension of the transition roller's own rotation.

[0026] Several conveying rollers are arranged behind the transition roller, the height of several conveying rollers is the same as the installation height of the transition rollers or lower than the transition rollers, and when lower than the transition rollers, an inclined surface is formed by the several conveying rollers and the transition rollers.

[0027] The bezel 8 is made of refractory material.

[0028] A tin ash collection and processing device and a tin ingot replenishment device are arranged in the recovery box 6 . The tin ash col...

Embodiment 3

[0032] As a further optimized design of implementation example 1, a flow meter is set at 8 places along the mouth to measure the flow rate of the tin liquid flowing out of the tin tank, calculate the height of the tin liquid level in the tin tank, and then adjust the flow rate by adjusting the tin liquid pump flow The height of tin liquid in the tank.

[0033] The formula for calculating the liquid level of the tin liquid: H=(2g -1 / 3 ×Q / mb) 2 / 3 , H: tin liquid level height at the overflow edge, g: gravity acceleration, Q: tin liquid flow rate, m: overflow coefficient characteristic value, b: edge width.

[0034] Such as figure 2 As shown, the structure is a structural schematic diagram of the prior art. Compared with the prior art, the present invention, through the design of the edge, diversion tank and recovery box, recycles tin liquid and places tin addition outside the tank, effectively avoiding the The intrusion of outside air and the structure of the edge and the tra...

Abstract

The invention provides a tin bath for a float glass forming process. A semicircular or arc-shaped tin bath edge opening is arranged at the tail end of a tin bath outlet; a flow-guiding groove is arranged at the outer side of the edge opening and connected with a bottom recovery box through a flow-guiding pipe; the recovery box is connected with the tin bath through a circulating pump and a liquidsupply pipe; the edge opening is lower than the surface of a tin liquid; the tin liquid flows out along the edge opening and flows into the bottom recovery box through the flow-guiding groove and theflow-guiding pipe; and the tin liquid is then conveyed into a tin bath body located in front of the edge opening from the liquid supply pipe through the circulating pump to form circulation. Accordingto the invention, through the design of the edge opening, the flow-guiding groove and the recovery box, the tin liquid is recovered, and tin is added and placed outside the groove, so invasion of outside air is effectively avoided; and through the structures of the edge opening and a transition roller, the defects of tin staining and tin ash are effectively prevented from generation, and plate breaking is prevented, so the conveying efficiency of the transition roller is improved, and the surface quality of a glass plate is guaranteed.

Description

technical field [0001] The invention relates to a tin bath for a float glass forming process, which belongs to the technical field of float glass production. Background technique [0002] The float method is a method in which the molten glass in the melting furnace flows into the tin bath to form flat glass on the surface of the molten metal tin liquid. The tin bath is the key thermal equipment for float glass forming. The tin bath is filled with tin liquid. The molten glass floats on the surface of the liquid, and under the control of a suitable temperature gradient, it is gradually shaped by the edge pulling machine to produce flat glass with the required thickness and width. After the glass plate is shaped, the glass plate needs to be led out to the transition roller at the end of the tin bath, and sent to the annealing furnace continuously. [0003] The tin tank body is a closed device composed of refractory materials and steel plates. The tin liquid is contained in the...
