Tin bath cooling water drum structure

Abstract

The invention discloses a tin bath cooling water drum structure. The tin bath cooling water drum structure comprises a row of water inlet pipes, a row of water return pipes, a steel plate shell and aheat preservation layer arranged in the steel plate shell; the row of water inlet pipes are arranged on one side of the steel plate shell, and the row of water return pipes are arranged on the side, deviating from the steel plate shell, of the row of water inlet pipes; and the water inlet pipes of the row of water inlet pipes are connected with the water return pipes of the row of water return pipes in one-to-one correspondence. The structure enables cooling water to flow in a water drum more reasonably, thereby effectively reducing or eliminating deformation and pollution of the tin bath water drum to a glass plate strip, improving glass quality, and being simple in structure, low in cost, high in economic benefit and high in feasibility.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a tin bath cooling water bag structure. Background technique [0002] The tin bath is the core thermal equipment of the float glass forming process. The high-temperature molten glass is flattened, polished, thinned or stacked in the tin bath to the required thickness, and then cooled to reach the final forming temperature and temperature. Viscosity, into the annealing kiln. Among them, cooling is a very critical process. The tin bath cooling water bag is currently the most commonly used cooling equipment for tin baths. It is usually welded by one or more sets of square or circular pipes side by side. The temperature is different, the viscosity of the glass is also different, because the temperature of the middle of the glass strip in the tin bath is higher than that of the edge, there is a difference in viscosity, resulting in a higher stretching rate in the middle than...

AI Technical Summary

Problems solved by technology

In addition, due to the combination of alternating cold and heat formed by the return water pipe and the water inlet pipe, the longitudinal temperature of the glass plate is uneven, and deformation such as warping is easy to occur.

Moreover, since the temperature of the cooling water in the water inlet pipe of the water bag fluctuates greatly with the room temperature, when the water temperature is too low, it is easy to increase the cooling of the top cover of the tin tank, resulting in increased condensate on the tank top, polluting the tank, and also causing damage to the glass plate. Excessive cooling will cause deformation of the glass strip such as corrugations
