The invention discloses an intelligent hot-
air drying control device which comprises a heat exchange box and a
drying chamber, wherein he heat exchange box is separated into multiple spaces, and the
drying chamber is connected with the heat exchange box through an air supplying main
pipe and a general air return
pipe. A
heat pump dehumidifying and
heating system, a
heat pipe return heat exchange
system, a hot air circulating
system and an
intelligent control system are arranged in the heat exchange box. The
heat pump dehumidifying and
heating system which is composed of a compressor, a
drying filter, a dehumidifying
evaporator, a
throttle valve and a heating condenser. The
heat pipe return heat exchange system is composed of a
heat pipe evaporator and a heat
pipe condenser. The hot air circulating system is composed of a high-pressure
refrigerant liquid connecting pipe, a low-pressure
refrigerant return gas connecting pipe, a high-pressure
refrigerant gas connecting pipe, a liquid refrigerant connecting pipe, a gas refrigerant connecting pipe, an air exhaust regulating valve, a mixed air box, a
fresh air regulating valve, a secondary air flow regulating valve and an
air blower assembly. The
intelligent control system is composed of the a temperature sensor, a
humidity sensor, a hot
air temperature sensor and a hot
air humidity sensor, wherein the temperature sensor, the
humidity sensor, the hot
air temperature sensor and the hot
air humidity sensor are connected in the various systems. The intelligent hot-
air drying control device can regulate the temperature and the
humidity of drying air automatically and improve the material drying efficiency.
