Tin bath for forming float glass

Abstract

The invention discloses a tin bath for forming float glass. A connecting plate is fixed in a bath body; the interior of the bath body is divided into a processing tank and a heating tank by the connecting plate; the heating tank is located under the processing tank; a temperature control device, circulating devices and a baffle are fixed in the processing tank; the two ends of the baffle are fixedtogether with the side walls of the heating tank; openings are formed between the other two ends of the baffle and the side walls of the heating tank; the circulating devices are arranged on the middle parts of the openings; each circulating device comprises a stirring shaft, a connecting gear, a driving gear, a driving chain and a driving motor; the two ends of the stirring shaft are in rotatable connection with the side walls of the heating tank by bearings; one end of the stirring shaft penetrates through the heating tank and is fixed together with the connecting gear; the connecting gearis in meshed connection with the driving gear through the driving chain; an output shaft of the driving motor is fixed together with the driving gear. The tin bath for forming the float glass is capable of improving the uniformity of the temperature of the liquid tin in the processing tank and is capable of avoiding the phenomenon of uneven thickness in the glass forming process.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a tin bath for forming float glass. Background technique [0002] Glass is formed by melting silicon dioxide and other chemicals together (the main production materials are: soda ash, limestone, quartz). A silicate-based non-metallic material that forms a continuous network structure during melting, and gradually increases in viscosity and hardens during cooling to cause it to crystallize. [0003] In the process of forming glass, it is necessary to put the molten glass body into the tin bath for float forming processing. Most of the existing tin baths directly heat the tin liquid through heating tubes, and the tin liquid cannot be heated in the tin bath. Flow, resulting in low temperature uniformity of tin liquid, resulting in uneven thickness of glass during molding, reducing the qualified rate of glass molding. Contents of the invention [0004] Aiming at the defi...
