Problems solved by technology

[0002] The transition roller table of the float glass production line is the connection part between the tin bath and the annealing kiln, an important equipment for the production of float glass. Ordinary float glass passes sulfur dioxide into the transition roller table to form a protective layer on the surface of the glass plate, but high-end Due to the high quality requirements of float glass and the high temperature at the exit of the tin bath, sulfur dioxide is introduced into the original transition roller table. Under high temperature, the excess sulfur dioxide will penetrate into the tin bath and seriously pollute the tin liquid in the tin bath, resulting in glass decline in quality

Embodiment Construction

[0015]Such asFigure 1-3As shown, a float glass annealing kiln sulfur dioxide injection device includes an annealing kiln 1. A track 2 distributed along the width of the annealing kiln 1 is welded on the top of the steel structure at a distance of 3000-3300 mm from the front end of the annealing kiln 1. The two ends of the track 2 correspond to the operation holes 1a on both sides of the inlet end of the annealing kiln 1.

[0016]The track 2 includes two C-shaped channel steels 2a distributed along the width direction of the annealing kiln 1. The two channel steels 2a are oppositely distributed, and there is a certain distance between the two channel steels 2a. Slideways 2b distributed along the axial direction of the two channel steels 2a are welded to the groove walls on one side.

[0017]A sprinkler 3 that can be inserted into the rail 2 is provided. The sprinkler 3 includes a rectangular tube-shaped main body 3a, both ends of the main body 3a are sealed structures, and one end of the m...

Abstract

The invention provides a sulfur dioxide injection device for a float glass annealing furnace, which comprises an annealing furnace (1) and is characterized in that a rail (2) is arranged in the annealing furnace (1), a sprayer (3) correspondingly matched with the rail (2) is arranged on the rail (2), and a first movable support (4) and a second movable support (5) correspondingly matched with thesprayer (3) are arranged on the outer side of the annealing furnace (1). The device is simple in structure, convenient to use and low in transformation cost, transformation can be conveniently conducted on the existing equipment, a protective layer can be formed on the upper surface of glass, escaped sulfur dioxide gas is prevented from entering a tin bath, the quality of a glass plate is improved, and potential quality hazards of glass production are reduced.

Description

Technical field:[0001]The invention relates to the technical field of float glass production, in particular to a float glass annealing furnace sulfur dioxide injection device.Background technique:[0002]The transition roller table of the float glass production line is the connection part of the tin bath and annealing furnace, an important equipment for the production and molding of float glass. The transition roller table of ordinary float glass is filled with sulfur dioxide to form a protective layer on the surface of the glass plate. Due to the high quality requirements of float glass and the high temperature at the tin bath outlet, sulfur dioxide is introduced into the original transition roller table. Under high temperature conditions, excess sulfur dioxide will penetrate into the tin bath, seriously polluting the tin liquid in the tin bath, resulting in glass decline in quality.Summary of the invention:[0003]In order to overcome the shortcomings in the prior art, this applicatio...
