Production structure of float glass

Abstract

The invention discloses a production structure of float glass. The production structure of the float glass comprises a glass melting furnace, wherein the glass melting furnace is connected with a neck, the neck is connected with a main line cooling part, one or more branch line cooling part is connected onto one side of the main line cooling part, the central axis of the main line cooling part is offset from the central axis of the glass melting furnace, and the central axis of the main line cooling part is offset to the side opposite to the branch line cooling part. In the invention, the central axis of the main line cooling part is properly offset to the opposite side of the branch line cooling part, so that more hot glass from the neck directly enters into a branch line channel to solve the temperature difference of glass liquid caused by different drawing quantities of a main line and a branch line so as to achieve one-kiln multi-line production of a large-tonnage float glass melting furnace, and meet market diversified demands while saving energy and reducing consumption.

Description

technical field [0001] The invention relates to a float glass production line, in particular to a float glass production structure. Background technique [0002] At present, the layout of float glass production lines at home and abroad is one kiln and one line. From the front to the back, there are float glass melting furnaces, necks, cooling parts, runners, tin baths, annealing kilns and cold ends. Two production lines are arranged in one factory building, and two glass furnaces must be installed respectively, and one furnace matches one tin bath. Corresponding combustion equipment, thermal instrumentation, automatic control system, feeding machine, fan and sluice plate and other process equipment need to use two sets, which has a large investment cost and does not meet the national energy saving and emission reduction requirements. At the same time, large glass melting furnaces, such as those above 900T / D, produce a single product, especially for the production of special...

Problems solved by technology

[0006] In the present invention, one or more branch channels and cooling parts are connected to one side of the front end of the cooling part of the main line (the rear end of the neck), so that a glass melting furnace is equipped with multiple production lines, that is, one main line plus one or more branch lines. At the same time, according to The various outputs of the main line and the branch line need to properly shift the central axis of the cooling part of the main line to the opposite side of the cooling part of the branch line, so that more hot glass from the neck can directly enter the channel of the branch line, thereby increasing the outlet temperature of the branch line and meeting the requirements of the branch line float process. The molding temperature needs to break through the difficult problem of not being able to effectively control the temperature of the glass melt, and solve the difference in the temperature of the glass melt caused by the difference in the flow distance of the main line and the branch line glass and the difference in the pulling amount of the main line and the branch line, and realize the large-tonnage float glass melting. The multi-line production of one kiln solves the problem of single product in the existing production line while saving energy and reducing consumption. A glass melting kiln can be used to produce different types of glass at the same time, meeting the diverse needs of the market
