Technical Field
The invention belongs to the field of float glass production, and particularly relates to a device for blocking gas flow under a transition roller table.
Background
In the production of float glass, molten glass is formed in a tin bath, then enters an annealing kiln through a transition roller table, and is annealed and cut into glass products. In the lower space of the transition roller table part, due to the temperature difference, the hotter gas at the outlet of the upper tin bath flows upwards and flows to the outside through the gap between the tin bath and the annealing furnace top cover. This flow also affects the space below the roller table, so that the gas flows partially to the outlet of the upper tin bath, and the gas in other parts (such as the annealing kiln) is supplemented correspondingly. The non-protective gas is supplemented to the position, the oxygen content is high, and after the non-protective gas is supplemented to the position below the transition roller table, the oxygen in the non-protective gas can permeate into a tin bath along with airflow, so that the oxidation of tin liquid is caused, the excessive tin ash is caused, and the quality of glass is influenced.
The original graphite strips under the roller can play a role in separation, but the graphite strips are easy to damage in the process of long-term use in a high-temperature environment, and the jacking mechanism under the graphite strips influences the jacking effect because tin slag or other pollutants are adhered to the jacking mechanism, and the space under the roller is always in an untight sealing state in the period from the damage of the original separation mechanism to the maintenance.
