Bending glass tempering and blast cooling device and cooling method thereof

Abstract

The invention discloses a bending glass tempering and blast cooling device and a cooling method thereof. The cooling device consists of a blast blower, an air power buffering chamber, an upper air chamber, a lower air chamber, an upper air outlet grid, a lower air outlet grid and a connecting pipeline. The upper air chamber and the lower air chamber are respectively provided with a plurality of air distributing channel outlets; the air chambers are manufactured to have inclined rectangular pyramid structures according to the air power distribution principle, so that each air distribution channel outlet has uniform air quantity and air pressure, and connected with one air outlet grid; and the air outlet grid consists of an interface and a plurality of rectangular-pyramid-shaped air grid sheets formed according to the air power distribution principle, a plurality of small air outlets are arranged on one surface of the air grid sheet, corresponding to glass to be cooled, air from the blast blower enters the air power buffering chamber for buffering, then enters the air chambers and is uniformly distributed to all the air grids by the air chambers and then uniformly distributed to all the air grid sheets, and air blown from the small air outlets has uniform air quantity and air pressure, thereby realizing the uniform cooling on the whole piece of glass, and manufacturing excellent bending and tempering glass products.

Description

technical field [0001] The invention belongs to the technical field of glass manufacturing, and relates to equipment for the glass forming and tempering process, in particular to a curved glass tempering blast cooling device and a cooling method thereof. Background technique [0002] Tempered glass is ordinary glass after heat treatment process, which is characterized by the formation of a stress layer on the surface of the glass, which improves the mechanical strength and thermal shock resistance, and has a special fragment state after destruction. At present, the method of tempering glass is to heat the glass to a set temperature, and then quickly blow air to cool it and temper it. Manufacturers have been constantly improving and exploring. The quality of tempered glass mainly depends on the cooling speed and uniformity of cooling. When blast cooling is used, excessive wind speed and pressure, unevenness, etc. will cause dents or wind on the glass surface. Spots affect th...

Problems solved by technology

At present, the method of tempering glass is to heat the glass to the set temperature, and then quickly blow air to cool it and temper it. Manufacturers have been constantly improving and exploring. The quality of tempered glass mainly depends on the cooling speed and uniformity of cooling. When blast cooling is used, excessive wind speed and pressure, unevenness, etc. will cause dents or wind on the glass surface. Spots affect the appearance and use of the glass. The wind speed and pressure are too small to reach the cooling speed, which affects the tempering quality. The air outlet of the current blast cooling device has a large horn shape, a small nozzle shape, etc., a big horn shape The cooling of the glass is not uniform, and the small nozzle shape will cause the glass to form dents, which cannot meet the needs of producing high-quality tempered glass, especially high-quality curved tempered glass
