The invention discloses a
drying chamber capable of replacing an air valve by adjusting an inserting plate, and relates to the technical field of
drying. The
drying chamber comprises a temperature rising and
heat supply unit, a steel platform, an air pipeline and a drying working area, the temperature rising and
heat supply unit is installed on the steel platform, and the two ends of the bottom of the temperature rising and
heat supply unit are connected with an air supply
pipe and an
exhaust pipe correspondingly. Stand columns are evenly and fixedly installed at the bottom of the steel platform, the bottom of the air supply
pipe is divided into a left air
pipe and a right air pipe, and the bottom of the left air pipe and the bottom of the right air pipe communicate with a top sealing plate at the top of an inner
cavity wall. According to the drying chamber, the left air pipe and the right air pipe both seamlessly communicate with the inner
cavity wall, so that drying gas has no chance to escape to the external space, and compared with an air valve adjusting mode in the past, the scheme avoids
air pollution caused by leakage of a rotating shaft of the air valve and avoids the phenomenon that external air pipe yellowing and oil dripping is caused by leakage of the air valve, and the surface quality of equipment is poor.
