[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Reference Figures 1-3 , a multifunctional flue-cured tobacco drying house, including a heat-insulating storage body 1. The heat-insulating storage body 1 includes a flue-cured tobacco area for baking tobacco leaves and a placement area for placing equipment. A hanging tobacco skeleton 2 is detachably arranged in the flue-cured tobacco area, which can be assembled or disassembled according to different needs to increase the spatial layout types of the flue-cured tobacco area so as to be applicable to different drying materials.
[0021] A cold air door 8 is arranged on one side of the placement area away from the flue-cured tobacco area. When drying tobacco leaves, it can communicate with the outside to supplement fresh air in the drying house. Moisture discharge ports 9 are symmetrically arranged on both sides of the cold air door 8. When drying tobacco leaves, the moisture generated by drying the tobacco leaves can be discharged.
[0022] A circulating fan 3 is arranged at the top of the placement area. The circulating fan 3 can blow air downward to form an upward airflow in the heat-insulating storage body 1. A heating device 4 is arranged at the air outlet of the circulating fan 3, and the temperature inside the flue-cured tobacco area can be increased by heating the air at the air outlet of the circulating fan 3. The heating device 4 can be a biomass hot air furnace.
[0023] A top air return port 6 is arranged between the top of the placement area and the top of the flue-cured tobacco area, and a bottom air outlet 7 is arranged between the bottom of the placement area and the bottom of the flue-cured tobacco area. A placement mechanism is arranged in the flue-cured tobacco area, and the bottom of the placement mechanism is flush with the top of the bottom air outlet 7. A circulating air path from bottom to top is formed between the placement area and the flue-cured tobacco area. The air passes through the circulating air path to contact the heat generated by the heating device 4 with the materials in the flue-cured tobacco area, realizing the drying of the materials and taking away the moisture generated during the drying process of the materials, and discharging it from the moisture discharge port 9.
[0024] At the top of the flue-cured tobacco area, there is a movable door 10 of the tobacco loading chamber that can be automatically opened and closed. The movable door 10 of the tobacco loading chamber in the open state can serve as a new forced moisture exhaust port, increasing the moisture exhaust efficiency of the flue-cured tobacco barn. On the surface of the movable door 10 of the tobacco loading chamber close to the heat preservation chamber body 1, there is a waterproof bead condensation layer, which can prevent water beads from condensing when the wind contacts the movable door 10 of the tobacco loading chamber during the moisture exhaust process from the movable door 10 of the tobacco loading chamber and falling into the flue-cured tobacco area, reducing the drying speed. One end of the movable door 10 of the tobacco loading chamber can be hinged to the top of the heat preservation chamber body 1. Between the side of the movable door 10 of the tobacco loading chamber close to the heat preservation chamber body 1 and the heat preservation chamber body 1, there can be an electric push-pull rod. Through the automatic expansion and contraction of the electric push-pull rod, the automatic opening and closing of the movable door 10 of the tobacco loading chamber can be realized. There can be at least two movable doors 10 of the tobacco loading chamber. By adjusting the number of opened movable doors 10 of the tobacco loading chamber, the drying requirements of different materials can be adapted, increasing the application range of the drying barn.
[0025] At the top of the placement area, there is a movable door 11 of the heating chamber that can be automatically opened and closed. The movable door 11 of the heating chamber in the open state can serve as a new forced fresh air inlet, increasing the air intake in the baking room. One end of the movable door 11 of the heating chamber can be hinged to the top of the heat preservation chamber body 1. Between the side of the movable door 11 of the heating chamber close to the heat preservation chamber body 1 and the heat preservation chamber body 1, there can be an electric push-pull rod. Through the automatic expansion and contraction of the electric push-pull rod, the automatic opening and closing of the movable door 11 of the heating chamber can be realized.
[0026] The placing mechanism includes a grid-shaped bottom baking rack 5 arranged at the bottom of the flue-cured tobacco area. The bottom of the bottom baking rack 5 is flush with the top of the bottom air outlet 7. The bottom baking rack 5 can be welded into a plane using steel bars and be flush with the top of the air outlet 7. Cross-grid welding can be adopted. The grid opening size of the bottom baking rack 5 can be larger than 150mm * 150mm to avoid the grid opening size being too small, which affects the air circulation, thus affecting the formation of the circulating air path and the drying of the materials in the flue-cured tobacco area.
[0027] The placing mechanism also includes a fine gauze net 12 detachably arranged on the bottom baking rack 5. When drying other materials, the materials can be laid on the fine gauze net 12 to improve the drying efficiency of the flue-cured tobacco barn for the materials.
[0028] The specific working principle is as follows:
[0029] When it is necessary to dry tobacco leaves, the movable door 10 of the tobacco loading chamber and the movable door 11 of the heating chamber are forced to close. The hanging tobacco skeleton 2 is installed in the flue-cured tobacco area, and the circulating fan 3 and the heating device 4 are started. A circulating air path is formed between the flue-cured tobacco area and the placement area to dry the tobacco leaves. This is the prior art and will not be elaborated here.
[0030] When it is necessary to dry materials suitable for kang-style drying, such as rice, peppers, etc., the hanging tobacco skeleton 2 in the flue-curing area is removed, and a fine wire mesh 12 is laid on the bottom kang rack 5. At the same time, the movable door 10 of the loading chamber and the movable door 11 of the heating chamber are opened to switch the drying room into a kang-style drying room. The circulating fan 3 and the heating device 4 are turned on. The outside air enters the placement area from the movable door 11 of the heating chamber and the cold air door 8, and is blown towards the heating device 4 under the action of the circulating fan 3. The heat intake device 4 heats the air to form hot air. The hot air enters the flue-curing area through the bottom air outlet 7, flows through the bottom kang rack 5 and the fine wire mesh 12 to contact the materials to be dried, and dries the materials. The air flowing through the materials carries the moisture of the materials and is discharged from the opened movable door 11 of the heating chamber, completing the drying of the materials.
[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
