[0015] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate the understanding of technicians.

[0016] like Figure 1-3As shown, the utility model provides a fresh rosemary drying room, comprising a room body 1, a hot air furnace 2, and a fan 3. A filter screen 4 for stacking rosemary is installed on the inner wall of the room body 1, and an isolation space 5 is formed between the filter screen 4 and the room bottom. The hot air furnace 2 is provided with a plurality of heating chambers 6 installed at the rear side of the room body 1 and separated from the room body 1; the fan 3 is installed in ventilation holes Ⅰ7 evenly opened on the rear wall of the room body 1, and the ventilation holes Ⅰ7 are located below the filter screen 4 and communicated with the isolation space 5 below the filter screen 4; a return air chamber 8 connected to the upper end of the heating chamber 6 is arranged on the top of the room body 1, and a ventilation hole Ⅱ9 connected to the room body 1 is opened at the front end of the return air chamber 8, and the fan 3 is installed in the ventilation hole Ⅱ9. When the drying room is working, rosemary is piled on the filter screen 4, coal is burned in the hot blast furnace 2 to generate heat, the fan 3 in the ventilation hole I7 rotates to form an airflow, and the hot air in the heating chamber 6 is blown into the bottom of the rosemary. At the same time, under the rotation of the fan 3 in the ventilation hole II9, an airflow from bottom to top is formed in the room body 1, so that the hot air passes through the rosemary from bottom to top to dry the rosemary, and the hot air enters the return air chamber 8 from the ventilation hole II9, and is heated again when flowing back to the heating chamber 6, thereby forming a hot air circulation system of the heating chamber 6-room body 1-return air chamber 8-heating chamber 6, thereby reducing the heating time of the hot blast furnace 2 to the air, rapidly raising the air temperature, improving the heating efficiency of the hot blast furnace 2 to the air, making the hot air circulate in the room body 1, reducing the heat loss, and improving the drying efficiency of the rosemary.

[0017] The installation structure of the fan 3 in the ventilation hole I7 and the ventilation hole II9 is ​​the same. The fan 3 is rotatably installed on the bifurcated support frame 10 installed in the ventilation hole I7. The rotation shafts of the fans 3 in adjacent ventilation holes I7 are connected by belt transmission, and the rotation shaft of one of the fans 3 is connected to the motor 11. The motor 11 drives the fans 3 in the ventilation holes I7 and the ventilation holes II9 to rotate, thereby forming an airflow, so that the hot air is blown from the heating chamber 6 to the room body 1 to heat and dry the rosemary, and then flows back from the ventilation hole II9 to the heating chamber 6 for reheating, forming a hot air circulation, and increasing the drying effect.

[0018] The top of the hot blast furnace 2 is connected with a smoke exhaust pipe 12, which passes through the upper part of the room body 1 and extends from the front of the room body 1 to the outside of the room body 1. The smoke generated by the combustion of coal in the hot blast furnace 2 is discharged from the smoke exhaust pipe 12 to the outside of the room body 1. At the same time, the smoke contains a large amount of heat. The smoke exhaust pipe 12 passes through the upper part of the room body 1, which can transfer part of the heat of the smoke into the room body 1 to increase the temperature in the room body 1, thereby improving the heat utilization rate.

[0019] The side wall of the hot blast furnace 2 is connected to an opening 13 provided on the side wall of the heating chamber 6, and a door cover 14 is installed at the opening 13. Fuel can be conveniently added to the hot blast furnace 2 through the opening 13, so that the hot blast furnace 2 generates heat continuously.

[0020] A water vapor absorption chamber 15 is installed between the return air chamber 8 and the heating chamber 6, and the side wall of the water vapor absorption chamber 15 is an isolation net 16. A desiccant is installed in the water vapor absorption chamber 15. After the hot air in the room body 1 dries the rosemary, a large amount of water vapor will be carried. When the air flow with water vapor passes through the desiccant in the water vapor absorption chamber 15, the water vapor is absorbed by the desiccant, so that the hot air dries the rosemary.

[0021] A cover plate 17 that is easy to open is installed on the top of the water vapor absorption chamber 15. By opening the cover plate 17, the desiccant can be replaced to improve the absorption efficiency of the desiccant to water vapor.

[0022] Working process:

[0023] When the drying room is working, rosemary is piled on the filter screen 4, coal is burned in the hot blast furnace 2 to generate heat, the fan 3 in the ventilation hole I7 rotates to form an airflow, and the hot air in the heating chamber 6 is blown into the bottom of the rosemary. At the same time, under the rotation of the fan 3 in the ventilation hole II9, an airflow from bottom to top is formed in the room body 1, so that the hot air passes through the rosemary from bottom to top to dry the rosemary, and the hot air enters the return air chamber 8 from the ventilation hole II9, and is heated again when it flows back to the heating chamber 6, thereby forming a heating chamber 6-room body 1-return air chamber 8- The hot air circulation system of the heating chamber 6 reduces the heating time of the hot air stove 2 for the air, causes the air temperature to rise rapidly, improves the heating efficiency of the hot air stove 2 for the air, causes the hot air to circulate in the room body 1, reduces the heat loss, and improves the drying efficiency of the rosemary; after the hot air in the room body 1 dries the rosemary, a large amount of water vapor will be carried, and when the airflow with water vapor passes through the desiccant in the water vapor absorption chamber 15, the water vapor is absorbed by the desiccant, thereby facilitating the drying of the rosemary by the dry hot air.

[0024] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
