Single-furnace multicolor float glass production line

Abstract

The invention relates to a single-furnace multicolor float glass production line. The shortcomings of difficulty in color changing of a melting furnace, long coloring period and high raw material waste rate and glass scrap rate, which are caused by the coloring of conventional colored glass at the position of the melting furnace, are overcome. The production line comprises a large-tonnage melting furnace and a primary constricted neck, wherein a flow division device is connected behind the primary constricted neck, and is provided with a plurality of flow passages for dividing molten glass discharged from the primary constricted neck; a secondary constricted neck, a cooling part, a float glass production tin bath and a subsequent device are sequentially connected to each flow passage; a return liquid baffle plate is arranged at an inlet of the secondary constricted neck of each flow passage; a coloring device is arranged behind each return liquid baffle plate. According to the production line, the coloring devices are arranged at the inlets of the secondary constricted necks, and a formula for producing colored glass by virtue of a small-tonnage melting furnace can be utilized, so that the burden of a raw material processing procedure is reduced; coloring materials in each flow passage can be different, so that the aim of simultaneously producing different colored glass by one large-tonnage melting furnace is fulfilled.

Description

technical field [0001] The invention relates to a float glass production equipment, in particular to a single-kiln multi-color float glass production line capable of simultaneously producing glasses of different colors. Background technique [0002] At present, the production of colored glass in the float glass industry is mainly based on the practical body coloring technology. The advantage of this method is that the coloring is uniform, there is no color difference, and the appearance of the product is exactly the same color. With the maturity of the production technology, it is suitable for mass production. But in this method, a melting furnace can only produce glass of one color. To produce a variety of different colors of glass, it is necessary to replace the pigment for color transfer treatment. Changing the melting furnace from one color to another takes a long time for color change, during which scrapped glass is likely to be generated, resulting in waste of raw mat...

Problems solved by technology

[0006] The invention solves the defects that the existing colored glass is colored at the position of the melting furnace, which causes difficulty in color changing in the melting furnace, long color changing period, waste of raw materials and scrapped glass, and provides a single kiln multi-color float method In the glass production line, the molten glass of the large-tonnage melting furnace is divided into multiple float glass production lines through the diverting device, and a coloring device is installed on each diverted production line, which does not affect the melting of the melting furnace, and at the same time reduces the influence of the coloring material on the glass liquid , or even if there is waste, it is only a waste of a production line, and will not cause waste of molten glass in the melting furnace, reducing production costs
