Oversized laminated glass autoclave

Abstract

The invention relates to an oversized laminated glass autoclave. An annular air guide plate is fixed to the position, close to the kettle wall, from the top to the lower portion in a kettle body, a kettle body annular air channel is formed between the kettle wall and the air guide plate, lower air outlets are formed in the two sides of the lower portion of the kettle body respectively, middle air openings capable of being opened are formed in the middles of the two sides of the air guide plate respectively, and a detachable horizontal baffle is connected above the position between the two middle air openings; and a fan is fixed at the top of the air channel, a heater and a cooler are fixed on the upper side of the air channel, the fan is fixed in a volute, the volute is respectively provided with an openable upper air outlet opposite to the two upper air channels, and the air inlet of the fan is communicated with one upper air channel through a detachable air guide pipe. According to the invention, wind is changed from the length direction of the original horizontal autoclave to the semicircular annular direction, so that the circulating distance of the air channel is shortened, the circulating frequency is increased, the uniform cooling degree of the whole glass is greatly improved, all indexes of the large glass are ensured to be qualified, rainbow spots are avoided, and the appearance and performance indexes are perfect.

Description

technical field [0001] The invention relates to the field of glass deep processing, in particular to a super-large laminated glass autoclave lamination method. Background technique [0002] Glass products are not only limited to indoor lighting, but also become a part of beautifying life. Glass curtain walls, glass load-bearing walls, glass load-bearing columns, etc. need to withstand certain pressure, and the thickness of single glass is limited, so laminated glass is produced. Laminated glass is made of two or more pieces of glass with one or more layers of organic polymer intermediate film between them. A bonded composite glass product. Commonly used laminated glass interlayers are: PVB, SGP, EVA, PU, ​​etc. Laminated glass is called safety glass. After being broken by impact, due to the bonding effect of the PVB film sandwiched between two pieces of ordinary glass, it will not produce sharp fragments to hurt people like ordinary glass. At the same time, the sound ins...

Problems solved by technology

The purpose of this cycle is to make the temperature in the autoclave cavity uniform, see figure 1 , 2 But this method is only suitable for short glass. If the glass is longer than 15 meters, the wind force will be blocked halfway and the wind speed will decrease, resulting in a large temperature difference between the front and rear ends of the inner cavity of the kettle; During the process, the temperature of the whole glass is consistent, so rainbow spots appear on the surface of the glass to varying degrees, seriously affecting the appearance and performance of the glass
