The glass autoclave is a pressure vessel that seals the forced convection internal circulation heating, in which the temperature, pressure and vacuum are effectively controlled.The temperature and pressure can be obtained according to the set process curve.Adapt to various process requirements of laminated glass production.In particular, the intermediate membrane for PVB or SGP material products, and to ensure the best product quality and yield.Equipped with safety interlocking system, kettle door opening and closing equipped with mechanical and electrical interlocking device, the kettle can not open the door under pressure;Over - temperature and over - pressure automatic alarm, over - temperature automatic cooling, over - pressure automatic unloading.The forced convection system (hot air circulation) adopts the u-shaped wind duct structure. The air ducts are distributed on both sides and at the bottom of the kettle. There are diversion devices at the extension of the air duct.The air duct at the bottom, on the one hand, makes the temperature at the bottom be compensated, on the other hand, increases the air duct area, makes the forced convection efficiency in the kettle reach more than 90%, and guarantees the rate and uniformity of temperature rise.The heating system is composed of the main heating zone and the auxiliary heating zone. The heating elements are distributed in the tail of the kettle and the air ducts on both sides of the kettle to ensure the uniformity of the temperature in the kettle during the heating process and shorten the heating time to achieve the purpose of energy saving.The coil cooler is arranged on both sides of the kettle, which is used as auxiliary cooling. The integral galvanized seamless boiler tube + aluminum fin makes the heat exchange efficiency high, the service life is long, and it is easy to maintain.This structure can be used for super long kettle, and the cooling effect is obvious.
