Description

Technical Field

[0001] This utility model relates to the field of smoke drying room technology, specifically to an intelligent smoke drying room structure with internal hot air circulation. Background Technology

[0002] After tobacco leaves are harvested, respiration continues as the leaves detach from the parent plant until they cease to function. During this process, a series of physiological and biochemical reactions occur inside the leaves through the action of respiratory enzymes: the contents are continuously decomposed, transformed, and synthesized. The curing of tobacco leaves is completed in a suitable temperature and humidity environment. However, the curing of air-cured tobacco (Bury tobacco, Maryland tobacco) is completed entirely under the natural temperature and humidity conditions in the drying room. Therefore, the curing of air-cured tobacco is based on the drying shed, and the curing of tobacco leaves is completed by regulating the temperature and humidity inside the shed.

[0003] In the existing technology, the roof of the tobacco drying room is made of double-layer plastic resin tiles, and a humidity-regulating layer is added at the bottom to achieve a good heat preservation and humidity regulation effect, which can make the tobacco drying effect in the drying room better.

[0004] However, in actual use, because the air inside the drying room does not circulate, when exposed to direct sunlight, the heat will accumulate at the top of the drying room, while the heat at the bottom will be lower. This will cause uneven temperature distribution inside the drying room, resulting in uneven drying of the tobacco. Utility Model Content

[0011] This invention provides an intelligent tobacco drying chamber structure with internal hot air circulation. It offers the following advantages: This intelligent tobacco drying chamber structure, through the cooperation of a controller, fan, and connecting pipes, uses a controller to time the fan's operation, causing the air inside the chamber to circulate through the collection box, connecting pipes, and exhaust box. This ensures a more even temperature inside the chamber, solving the problem of uneven temperature distribution in drying chambers where the air doesn't circulate properly, and heat accumulates at the top when exposed to direct sunlight, resulting in uneven tobacco drying.

[0012] Through the cooperation of the collection box, baffle and first gear, when the circulation device is not working, the baffle will seal the side opening of the collection box under the drive of the drive device, so as to prevent impurities from entering the collection box when it is not in use, which would cause damage to its internal parts. This solves the problem that the air inlet of the existing circulation device is exposed and impurities are easy to enter. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In actual use, because the air inside the drying room does not circulate, when exposed to direct sunlight, the heat will accumulate at the top of the drying room, while the heat at the bottom will be lower. This will cause uneven temperature distribution inside the drying room, resulting in uneven drying of the tobacco.

[0017] In view of this, the present invention provides an intelligent tobacco drying room structure with internal hot air circulation, which solves the problem that in actual use, because the air in the drying room does not circulate, the heat will accumulate at the top of the drying room after being exposed to direct sunlight, while the heat at the bottom is lower. This will lead to uneven temperature distribution in the drying room, resulting in uneven drying of tobacco.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0019] Example 1: By Figure 1-4It is known that a smart smoke drying room structure with internal hot air circulation includes a chamber 1. A collection box 5 is fixedly connected to the bottom of the inner wall of the chamber 1. A fixed shell 11 is connected to the top of the collection box 5. A fan 6 is fixedly connected to the inner wall of the fixed shell 11. A controller 4 is electrically connected to the fan 6. The outer wall of the controller 4 is fixedly connected to the outer wall of the chamber 1. A connecting pipe 7 is connected to the top of the fixed shell 11. The outer wall of the connecting pipe 7 is fixedly connected to the inner wall of the chamber 1. An exhaust box 8 is connected to the top of the exhaust box 8. A bracket 9 is fixedly connected to the top of the exhaust box 8. The top of the bracket 9 is fixedly connected to the top of the inner wall of the chamber 1. In the specific implementation process, it is worth noting that an opening is provided on the side of the collection box 5, which allows the gas in the room to enter under the drive of the fan 6. The gas will be transported to the top of the inner wall of the chamber 1 through the connecting pipe 7 and the exhaust box 8, thus forming a circulation inside. This can ensure that the temperature inside the chamber 1 is balanced. The operator can set the working time of the circulation device through the controller 4, which can save manpower. The interior of the chamber 1 is equipped with a rack for hanging tobacco, which is not shown in the figure. Furthermore, a protective net 12 is provided below the fan 6, and a mounting frame 13 is fixedly connected to the outer wall of the protective net 12. The outer wall of the mounting frame 13 is inserted into the inner wall of the fixed shell 11, and the mounting frame 13 extends to the outside of the fixed shell 11 and is fixedly connected to the outer wall of the fixed shell 11. In the specific implementation process, it is worth noting that when the gas in the chamber 1 is circulating, the impurities in the gas will be removed by the filter of the protective net 12, which can prevent impurities from damaging the parts. At the same time, when the protective net 12 is replaced, the mounting frame 13 can be removed from the fixed shell 11. Furthermore, the controller 4 is electrically connected to the temperature control switch 3, the outer wall of the temperature control switch 3 is fixedly connected to the inner wall of the chamber 1, the temperature control switch 3 is electrically connected to the heat source dryer 2, the heat source dryer 2 is fixedly connected to the outer wall of the chamber 1, and the heat source dryer 2 is electrically connected to the outer wall of the chamber 1. In the specific implementation process, it is worth noting that the controller 4 can limit the trigger temperature of the temperature control switch 3. When the temperature inside the chamber 1 drops to the temperature triggered by the temperature control switch 3, the temperature control switch 3 will turn on the heat source dryer 2, which will heat the chamber 1. At the same time, when the temperature reaches the highest temperature of the temperature control switch 3, the temperature control switch 3 will turn off the heat source dryer 2. Meanwhile, the controller 4 will control the circulation device to work, so that the gas inside the chamber circulates, thereby ensuring the temperature inside the chamber 1 is stable.

[0020] Example 2: From Figure 1-4It can be seen that the inner wall of the collection box 5 is rotatably connected to the baffle 10 through the sealed bearing, and the baffle 10 is fixedly connected to the first gear 14 at one end extending to the top of the collection box 5. The outer wall of the first gear 14 is equipped with a drive device. In the specific implementation process, it is worth noting that there are three baffles 10. When the first gear 14 rotates 90 degrees, the end faces of each baffle 10 will press together, thereby closing the opening of the collection box 5. At the same time, rubber pads are provided on the side of the baffles 10. When the baffles 10 press together, the gaps between the baffles 10 will be sealed by the action of the rubber pads, thereby preventing leakage and preventing external impurities from entering the collection box 5. Under the control of the controller 4, the drive device controls the baffles 10 to open or close the collection box 5. Furthermore, the drive device includes a protective shell 16, which is disposed on the outer wall of the first gear 14. The bottom of the protective shell 16 is fixedly connected to the top of the collection box 5. A rack 19 is connected to the inner core of the outer wall of the first gear 14. A limit block 18 is slidably engaged with the inner wall of the rack 19. The bottom of the limit block 18 is fixedly connected to the top of the collection box 5. A second gear 17 is meshed with the other side of the rack 19. The top of the second gear 17 is rotatably connected to the inner wall of the protective shell 16 through a sealed bearing. A servo motor 15 is fixedly connected to one end of the second gear 17 that extends outside the protective shell 16. The outer wall of the servo motor 15 is fixedly connected to the top of the protective shell 16. The servo motor 15 is electrically connected to the controller 4. In the specific implementation process, it is worth noting that the first gear 14 and the second gear 17 are the same size and can mesh with the outer wall of the rack 19. There are two limiting blocks 18, which can ensure stable movement. When the servo motor 15 drives the second gear 17 to rotate, the rack 19 will move on the outer wall of the limiting block 18. At the same time, the rack 19 will drive the first gear 14 to rotate, thereby causing the first gear 14 to drive the baffle 10 to rotate, thereby opening or closing the side of the collection box 5.
