[0030] The spoiler 5 is located in the mixed air chamber 4 opposite to the third air inlet 401, the spoiler 5 is a plate structure, coaxial rotating shafts 6 are arranged at both sides of the length direction of the spoiler 5, and the rotating shafts 6 are movably installed in the mixed air chamber 4, for adjusting the deflection angle of the spoiler 5 relative to the horizontal direction.

[0031] In the embodiment, part of the high-temperature and high-humidity airflow in the drying equipment 3 can be introduced into the second air supply cavity 2 through the second air inlet 201, and then introduced into the mixed air chamber 4 from the second air outlet 202, mixed with the hot air introduced from the first air supply cavity 1 in the mixed air chamber 4, and then introduced into the drying equipment 3 through the third air outlet 402, so as to realize the drying of the materials in the drying equipment 3, improve the heat utilization rate, and reduce the energy consumption.

[0032] In the embodiment, the air supply device includes a plurality of air supply units, each air supply unit includes one first air supply cavity 1 and one second air supply cavity 2. In each air supply unit, the first air supply cavity 1 is used to introduce external hot air, and the second air supply cavity 2 is used to re-introduce part of the high-temperature and high-humidity airflow in the drying equipment 3, so as to realize the recycling of heat. Each air supply unit can work independently, and especially can flexibly adjust the air supply amount according to the actual demand in the drying equipment 3, thereby improving the adaptability and drying efficiency of the air supply device. It should be noted that each air supply unit includes an independent mixed air chamber 4 or multiple air supply units share the same mixed air chamber 4.

When multiple air supply units share the same mixed air chamber 4, the structure of the air supply device can be further simplified, and the manufacturing cost can be reduced.

[0033] Referring to Figure 3 and Figure 4In the specific implementation process, the air supply device includes a cabinet 7 arranged outside the drying equipment 3 along the length direction of the drying equipment 3, a plurality of partitions 8 are arranged in the inner cavity of the cabinet 7 along the vertical direction, the plurality of partitions 8 divide the inner cavity of the cabinet 7 into independent chambers, respectively forming a first air supply cavity 1 and a second air supply cavity 2, and the first air supply cavity 1 and the second air supply cavity 2 are arranged at intervals.

The first air supply cavity 1 and the second air supply cavity 2 are respectively located on the side or top of the corresponding chamber. The air supply device has a simple structure and is easy to manufacture.

[0034] In the embodiment, the partition 8 is a metal plate, and a heat-conducting fin 9 extending to the inner side of the corresponding chamber is further arranged on the partition 8. The arrangement of the heat-conducting fin 9 can enhance the heat conduction performance of the partition 8, so that the airflow in the first air supply cavity 1 and the airflow in the second air supply cavity 2 can be preliminarily exchanged through the heat-conducting fin 9 when the air supply device is running, thereby ensuring that the temperature in the mixing chamber 4 can reach a balanced state more quickly, and further improving the uniformity of the airflow temperature in the mixing chamber 4.

The number of spoilers 5 at the same air supply unit position can be one or more, and the specific number is set to achieve effective disturbance of the airflow entering the mixing chamber 4, thereby ensuring that the airflow is more fully mixed in the mixing chamber 4.

[0036] In the embodiment, one end of the rotating shaft 6 of the spoiler 5 extends out of the mixing chamber 4, and the end of the rotating shaft 6 outside the mixing chamber 4 is drivingly connected with a servo motor for adjusting the deflection angle of the spoiler 5 relative to the horizontal direction through the servo motor. The angle of the spoiler 5 is accurately controlled through the servo motor, the airflow mixing uniformity is optimized, and the temperature and humidity adjustment efficiency is improved.

[0037] In the embodiment, a wind guide plate 10 is arranged between the spoiler 5 and the third air outlet 402.

[0038] The function of the wind guide plate is to guide the airflow flowing out of the third air outlet to flow in a predetermined direction. The design of the wind guide plate can be streamlined to reduce the resistance of the airflow when passing through, thereby reducing the flow loss of the airflow at the third air outlet position. Through the cooperation of the wind guide plate and the spoiler, the temperature, flow direction and flow rate of the airflow can be accurately controlled, thereby meeting the requirements of the drying equipment for accurate temperature and humidity adjustment.
