SO2 coating device of float glass

Abstract

The invention provides a SO2 coating device of float glass. The SO2 coating device comprises a first crossbeam and a second crossbeam which are located at the two sides of a glass tape in an annealingkiln, wherein end parts of the first and second crossbeams are separately connected with fixing devices which are the same in structure and are used for fixing an injection pipe, the injection pipe is connected with a SO2 gas supply pipe, and a plurality of injection holes are uniformly distributed in the injection pipe along the axial direction and are directed to the glass tape. According to the SO2 coating device of the float glass, the injection holes are formed in the injection pipe along the axial direction and are used for injecting SO2 gas to the lower surface of the glass for coating; the SO2 coating device is relatively far away from a tin pot, so that the possibility that the SO2 gas reversely flows into the tin pot is reduced; meanwhile, an injection pipe can also be arrangedon a connecting plate, an up-and-down position can be adjusted, and the range and intensity of injection of the SO2 gas can be changed, so that the SO2 coating device has an important significance inimproving the quality of the glass.

Description

technical field [0001] The invention relates to the field of float glass production, in particular to a float glass SO 2 Coating device. Background technique [0002] At present, the float glass production line will place SO 2 Coating device, there are 1#, 2#, 3# and 4# rollers in sequence along the direction of glass advance, and the traditional method is to place SO 2 The injection pipe is between 1#, 2# rollers and 2#, 3# rollers. Glass is formed from the end of the tin bath into the hermetic box, SO 2 Tube jet SO 2 The gas is on the lower surface of the glass, at this time the SO at high temperature 2 The gas will have a chemical reaction with the glass. This reaction can solve the problem of glass tempering rainbow, and can also solve the problems of tin dust on the lower surface of the glass and reduce the abrasion and scratches on the lower surface of the glass. However traditional SO 2 The position of the coating device is relatively close to the tin bath, and...

Problems solved by technology

However traditional SO 2 The position of the coating device is relatively close to the tin bath, and the unreacted SO 2 The gas will flow back into the tin bath and pollute the tin bath. At the same time, due to the traditional SO 2 The coating device is fixed, and SO cannot be adjusted according to the actual situation of glass production. 2 Gas injection intensity and injection range
