Float glass molten tin bath tin ash cleaning device

Abstract

The invention discloses a float glass molten tin bath tin ash cleaning device. The float glass molten tin bath tin ash cleaning device comprises a top cover, two slide rails, four rolling wheels, a platform and an ash collection hopper. The ash collection hopper is located under the position between two roll shafts. A motor is mounted on the platform. The two roll shafts are each sleeved with a rotary drum. A rolling groove is formed in the axial direction of each roll shaft. One roll shaft is arranged in the corresponding rolling groove. Each rotary drum is in rotating fit with the corresponding roll shaft. The surface of each rotary drum is provided with bristles. According to the float glass molten tin bath tin ash cleaning device, the rotary drums are mounted on the rolling wheels, andthe rolling wheels and the rotary drums rotate under the transmission effect of the motor and are used for thoroughly cleaning tin ash adsorbed to the lower sidewall of the top cover to prevent the situation that the tin ash accumulates on the top cover of a molten tin bath for a long time, falls off and causes optical distortion to the glass surface.

Description

technical field [0001] The invention relates to the technical field of float glass, in particular to a cleaning device for tin dust in a float glass tin bath. Background technique [0002] Float method is one of the most advanced processes in modern glass production. It refers to a method in which glass also floats on the surface of molten metal to produce flat glass. It has the advantages of high output, good flatness, and stable operation. The biggest feature of float glass production is that the molding temperature is as high as 1100-1200 °C, which greatly exceeds the upper limit temperature of glass crystallization, making it difficult to crystallize during molding. Therefore, the short-term material of "high calcium, medium magnesium, low aluminum micro-iron" is generally used. This glass composition is suitable for high-speed drawing with the float process. [0003] When the glass is produced by the float forming process, after the glass is shaped and has a certain st...

Problems solved by technology

[0004] Even if the tin bath is well sealed, oxidizing or polluting gases will enter the tin bath due to some reasons, and the tin ash produced by the reaction of these gases with the tin liquid will accumulate on the top cover of the tin bath. It poses a great "threat" to the glass surface, manual cleaning needs to stop production, and the cost is huge

The invention mainly solves the problem of light distortion caused by frequent accumulation of tin ash on the top cover of the tin tank and tin ash falling on the glass
