Description

An air energy drying device

technical field

The utility model relates to an air energy drying device.

Background technique

Air energy drying is a new energy-saving drying technology. Air energy drying is to use the heat pump unit to convert the low-grade heat energy in the air that cannot be used for drying into high-grade heat energy that can be used for drying. It is used for drying processing. Compared with electric heating drying, air energy drying has high thermal efficiency and low energy consumption. , so it has been applied in some drying fields. Compared with coal-fired drying, the energy consumption cost of air energy drying is high, and its popularization and use are limited. Therefore, in order to further achieve energy conservation, environmental protection and high efficiency, an air energy drying drying equipment.

Contents of the invention

The technical problem to be solved by the utility model is to provide an air energy drying equipment for the shortcomings of the existing air energy drying, which has the characteristics of forced circulation of hot air, high air velocity, uniform air flow, and high drying efficiency.

An air energy drying equipment is composed of a drying chamber, a hot air circulation channel, a heat pump unit, a hot air circulation unit, a loading vehicle, an automatic control system and other components. The heat pump unit consists of a heat pump main unit with a heat exchange fan and a heat pump auxiliary unit. The vertical partition and the horizontal partition divide the drying room into a drying room and a hot air circulation channel. The hot air circulation unit is composed of a circulation fan, a dehumidification fan, a gravity air supply port and a heat pump unit with its own fan.

The effect of the utility model is: the heat energy of the air absorbed by the heat pump unit is released by the heat pump auxiliary machine with a circulation extension unit, and under the action of the heat division circulation unit, passes through the material carried on the loading vehicle in the drying chamber and heats the material , into the hot air circulation channel for forced circulation, in which the humidity exhaust fan adjusts the humidity in the drying room. During the whole process, the automatic control system monitors the temperature and humidity in the drying room, and adjusts the heat pump unit and the heat distribution cycle unit according to the set drying process parameters, so as to achieve the adjustment of the temperature and humidity in the drying room.
