Description
Technical Field
[0001] The utility model relates to the technical field of baking rooms, in particular to a structure for airflow guidance and exhaust. Background Art
[0002] The airflow interactive curing room, also known as the circulating hot air curing room or hot air drying room, is a device that uses hot air circulation technology to dry materials. It heats the air and makes it circulate in the curing room to evenly heat and dry the materials. The airflow interactive curing room is equipped with a dehumidification structure, in which the dehumidification efficiency of the dehumidification window will affect the drying time of tobacco leaves. If the dehumidification is insufficient, the color of the tobacco leaves will appear as ash or blisters, resulting in poor quality of tobacco leaves. At present, the common curing rooms are usually rectangular in shape, with a door body at one end, a supplementary air window, a hot air generator and a circulating fan at the other end, and a dehumidification window at the corner of the room adjacent to the return air side of the circulating fan. The dehumidification structure formed by the rectangular room and the dehumidification window, when the airflow circulates in the room, the airflow velocity at the corner of the room is low, so the dehumidification effect is not good, and the corner of the room is not conducive to the guidance of the airflow circulation, and the uniformity of the airflow circulation needs to be further improved. Utility Model Content
[0003] The utility model aims to overcome the deficiencies in the prior art and provides a structure for airflow guidance and exhaust.
[0004] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] Preferably, the dehumidification window comprises a window frame, a window door, and a driving mechanism for driving the window door to open and close; one side of the window door is hinged to the window frame, and the window door rotates into the air guide shell when it is opened.
[0007] Preferably, one side of the window door is connected to the window frame via a rotating shaft; the window door is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the window frame; the driving mechanism is a servo motor, the servo motor is fixedly connected to the window frame, and the output shaft of the servo motor is coaxially fixedly connected to the rotating shaft.
[0008] Preferably, the driving mechanism is a linear driving element; two ends of the linear driving element are hinged to the window frame and the window door respectively.
[0009] Preferably, the driving mechanism is a linear driving element fixedly connected to the window frame, the output end of the linear driving element is hinged to a connecting rod, and the other end of the connecting rod is hinged to the window door.
[0010] Preferably, the linear drive element is a pneumatic cylinder, a hydraulic cylinder or an electric push rod.
[0011] Preferably, the window frame comprises an outer frame body, a retaining edge fixedly connected to the inner side of the outer frame and used for limiting the position of the window door, and a connecting plate fixedly connected to the outer side of the outer frame body; the connecting plate is provided with a mounting hole.
[0012] Compared with the prior art, the utility model has the following advantages:
[0013] (1) The utility model guides the airflow in the drying room through the guide shell. The guide shell is symmetrically arranged to form a trumpet shape, which can make the airflow circulation in the drying room more uniform. At the same time, the airflow in the drying room can be directly discharged toward the window hole of the dehumidification window when returning, and the dehumidification efficiency is further enhanced.
[0014] (2) The dehumidification window of the utility model can automatically rotate and open inside the dehumidification shell during the dehumidification process. When the window is fully opened inside the dehumidification shell, the window blocks and guides the circulating airflow inside the dehumidification shell. The airflow inside the dehumidification shell passes through the blocking and guiding effect of the window, and more airflow is directed to the outside of the dehumidification shell, so as to achieve the purpose of increasing dehumidification under the condition of the same window hole area. This design innovation avoids the undesirable phenomenon of dust or water bubble color on the surface of tobacco leaves due to insufficient dehumidification capacity, thereby ensuring that the tobacco leaves can maintain excellent quality during the baking process.
