Abstract

A D zone sealing apparatus of a glass anneal kiln includes an upper part and a lower part, wherein the upper part and the lower part and an anneal kiln roller table form a sealing barrier, thereby stopping influence on a C zone due to forced convection air in an R zone. According to the D zone sealing apparatus of the glass anneal kiln, a sealing barrier is formed with the anneal kiln roller table for stopping the influence on the C zone due to forced convection air in the R zone, so that the gas flow in an anneal front portion is stable, thereby ensure stability of internal atmosphere in the glass anneal kiln.

Description

technical field [0001] The invention relates to the improvement of the structure of the D area of ​​an annealing kiln, in particular to a sealing device for the D area of ​​a glass annealing kiln. Background technique [0002] The main task of the float glass annealing kiln is to create a uniform temperature field that is evenly heated and meets the needs of glass structure adjustment, to ensure the cooling rate of the glass ribbon in each zone of the annealing kiln, to reduce the structural difference between the various parts of the glass, and to form a controlled In the cooling process, in theory, we require the annealing environment of each zone to be independent, to reduce the interference of the atmosphere caused by the air circulation between zones, and to meet the temperature drop and annealing requirements of the glass ribbon in each zone. Zone D plays the role of connection and transition in the annealing kiln. There is no electric heating or cooling device in the ...
