Plate glass kiln clarification section tank bottom construction method

Abstract

The invention relates to the technical field of glass kiln, and provides a plate glass kiln clarification section tank bottom construction method. A support layer is laid on the bottom of the glass kiln; a first pavement structure is tiled on the support layer; the first pavement structure comprises multiple levels of horizontal steps which rise gradually along a molten glass flowing direction; adjacent horizontal steps are connected through inclined surfaces; and along the molten glass flowing direction, a second pavement structure is laid at the end of the highest level of horizontal step, wherein the second pavement structure is connected with the end of the highest level of horizontal step. The entire tank bottom of the clarification section is step-like. With the construction method, the height of the clarification section tank bottom is lifted, such that the depth of molten glass at that section is relatively reduced. Also, the depth of a surface flow layer at that section is reduced, such that flowing molten glass can slowly flow to a cooling section along the step-like clarification section tank bottom. Molten glass reflux amount is effectively reduced, such that energy consumption is reduced, and clarification rate is improved.

Description

technical field [0001] The invention relates to the technical field of glass furnaces, in particular to a method for constructing the bottom of a clarified part of a flat glass furnace. Background technique [0002] Glass furnaces are an extremely important part of glass production. A glass furnace is generally divided into a melting section, a clarification section, and a cooling section, and the clarification section and the cooling section are connected by a neck. The raw materials are melted in the melting section and enter the clarification section for clarification, and finally enter the cooling section through the neck for cooling. [0003] The bottom of the clarification section of the original flat glass furnace was built into a flat bottom type. The pool depth is the same as that of the melting section, both of which are 1.2 meters. During the melting process, there is more glass liquid in the clarification section. After cooling, it flows back to the melting sect...
