Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a tobacco leaf humidification device. Background Technology

[0002] In the tobacco processing industry, the humidification treatment of tobacco leaves is a crucial step, directly affecting the quality of the tobacco and the subsequent processing results. Currently, commonly used tobacco humidification cylinder equipment generally consists of a hollow cylinder, internally spirally distributed process pipes, lifting plates, rakes, humidifying and feeding nozzles, and a drive device. The cylinder is tilted downwards at a certain angle. During processing, the rotation of the cylinder drives the spirally distributed lifting plates and rakes to rotate together. Simultaneously, hot air, humidifying steam, and atomized liquid are applied at the feed end to lift the tobacco leaves and complete the processes of uniform heating, humidification, and liquid application. However, this traditional tobacco humidification cylinder equipment has many problems in actual operation. Because the tobacco leaves are rapidly heated and humidified during the equipment processing, and the required hot air, humidifying steam, and atomized liquid are all applied from the feed end, when the humidified tobacco leaves and process media reach the discharge end, the closed metal structure at the discharge end has excellent heat dissipation, leading to a series of production-related problems. On the one hand, the rapid cooling of humidifying steam forms condensate droplets, which mix into the material, causing excessive deviations in the moisture content of the tobacco leaves and failing to meet the uniformity requirements, seriously affecting the quality stability of tobacco products. On the other hand, the increased adhesion of the tobacco leaves after humidification makes them easily adhere to the inner metal wall at the discharge end. These adhered tobacco leaves absorb moisture over a long period of time, forming overly wet tobacco leaves that fall into the material, causing material contamination. This not only reduces product quality but may also lead to production interruptions, increasing cleaning and time costs.

[0003] In summary, existing tobacco humidification cylinder equipment suffers from serious problems at the discharge end that negatively impact production and product quality. Therefore, designing and manufacturing a tobacco humidification device with an anti-sticking function at the discharge end is particularly urgent. Utility Model Content

[0004] The purpose of this utility model is to provide a tobacco leaf humidification device, which aims to solve the problems of excessive deviation in the moisture content of tobacco leaves at the discharge end of the tobacco leaf humidification cylinder and the adhesion of tobacco leaves to the inner wall of the discharge end after humidification.

[0008] The discharge component is equipped with a discharge port and an exhaust port;

[0009] A humidifying cylinder, wherein the inlet end of the humidifying cylinder is connected to the inlet component, the outlet end of the humidifying cylinder is connected to the outlet component, and the height of the inlet end of the humidifying cylinder is higher than the height of the outlet end;

[0012] As a preferred embodiment of a tobacco leaf humidification device, the exhaust assembly further includes a second air duct, and the exhaust port further includes a second exhaust port. The second exhaust port is located on the side wall of the discharge component near the humidification cylinder. The air inlet end of the second air duct is connected to the second exhaust port, and the other end of the second air duct is connected to the first air duct.

[0013] As a preferred embodiment of the tobacco leaf humidification device, it also includes a conveying component located below the discharge port, which is used to transport the humidified tobacco leaves to the next stage; the exhaust assembly also includes a third air duct, with the air inlet end of the third air duct covering the portion of the conveying component located downstream of the discharge port along the conveying direction of the conveying component, and the other end of the third air duct being connected to the first air duct.

[0014] As a preferred embodiment of a tobacco leaf humidification device, the air inlet end of the third air duct is tapered, gradually widening towards the duct opening.

[0015] As a preferred embodiment of a tobacco leaf humidification device, the air extraction assembly further includes a fan. The air inlet of the fan is connected to the other end of the first air duct via a first pipe. The diameter of the first pipe gradually increases from the first air duct toward the fan. The air outlet of the fan is connected to a second pipe. The diameter of the second pipe gradually decreases from the fan toward the direction away from the fan.

[0016] As a preferred embodiment of the tobacco leaf humidification device, it also includes an adjustment component for adjusting the ventilation area inside the first duct.

[0017] As a preferred embodiment of a tobacco leaf humidification device, the adjustment assembly includes a lever and a baffle.

[0020] Beneficial effects:

[0021] This utility model provides a tobacco leaf humidification device, comprising: a feeding component with an inlet; a discharging component with an outlet and an exhaust port; a humidification cylinder with its inlet end connected to the feeding component and its outlet end connected to the discharging component, the height of the inlet end of the humidification cylinder being higher than the height of the outlet end; and an air extraction component with its inlet connected to the exhaust port of the discharging component. This device, by setting the height of the outlet end of the humidification cylinder lower than the height of the inlet end, allows the tobacco leaves to pass through the humidification device more smoothly. Simultaneously, the exhaust port on the discharging component facilitates air extraction. The air inlet of the component is connected to the exhaust port on the discharge part. Through the suction effect of the suction component, various process gases (hot air, humidifying steam, etc.) in the humidification cylinder can be promoted to flow towards the discharge part of the device. The process gases flowing to the discharge part of the device heat the wall surface of the discharge part, thereby reducing the temperature difference between the inlet and outlet directions of the device. This makes it less likely for the humidifying steam to condense into water droplets at the discharge part due to rapid cooling, thus reducing the moisture content of the humidified tobacco leaves. At the same time, it also makes it less likely for the humidified tobacco leaves to adhere to the inner wall of the discharge part. This tobacco leaf humidification device not only humidifies the tobacco leaves but also prevents excessive moisture content, resulting in more uniform humidification and improved product quality. Furthermore, it reduces the adhesion of humidified tobacco leaves to the inner wall of the discharge end, preventing long-term adherence and subsequent contamination of the material. This invention solves the problems of excessive moisture content deviation in the tobacco leaves at the discharge end of the humidification cylinder and the adhesion of humidified tobacco leaves to the inner wall of the discharge end.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0031] like Figure 1As shown, this embodiment provides a tobacco leaf humidification device, which mainly includes a feeding component 1, a discharging component 2, a humidification cylinder 3, and an extraction assembly 4. The feeding component 1 is provided with an inlet for inputting tobacco leaves; the discharging component 2 is provided with an outlet and an exhaust port. The outlet is used to output the humidified tobacco leaves, and the exhaust port cooperates with the extraction assembly 4 to promote the flow of humidifying steam to the discharging component 2 during the humidification process; the inlet end of the humidification cylinder 3 is connected to the feeding component 1, and the outlet end of the humidification cylinder 3 is connected to the discharging component 2, and the height of the inlet end of the humidification cylinder 3 is higher than the height of the outlet end. This inclined design facilitates the natural sliding of tobacco leaves under gravity, and, in conjunction with the process structure inside the humidification cylinder 3, achieves the humidification treatment of the tobacco leaves; the extraction assembly... The air inlet of component 4 is connected to the exhaust port of the discharge component 2. This device sets an exhaust port on the discharge component 2 and connects the air inlet of the suction component 4 with the exhaust port on the discharge component 2. Through the suction action of the suction component 4, various process gases (hot air, humidifying steam, etc.) in the humidification cylinder 3 can be promoted to flow towards the discharge component 2 of the device. The process gases flowing to the discharge component 2 of the device heat the wall surface of the discharge component 2, thereby reducing the temperature difference between the direction of the feed component 1 and the direction of the discharge component 2. This makes it less likely that the humidifying steam will form condensate droplets at the discharge component 2 due to rapid cooling, thereby reducing the moisture content of the humidified tobacco leaves. At the same time, it is also less likely that the humidified tobacco leaves will adhere to the inner wall of the discharge component. This tobacco leaf humidification device not only humidifies the tobacco leaves but also prevents the moisture content of the tobacco leaves from being too high, resulting in more uniform humidification and improved product quality. In addition, it reduces the phenomenon of humidified tobacco leaves adhering to the inner wall of the discharge part 2, preventing long-term adhered tobacco leaves from falling into the material and causing contamination.

[0032] Preferably, the extraction assembly 4 includes a first air duct 42 and an exhaust port including a first exhaust port 21. The first exhaust port 21 is located on the side wall of the discharge component 2 away from the humidification cylinder 3. The air inlet end of the first air duct 42 is connected to the first exhaust port 21. The first air duct 42 is connected to the first exhaust port 21 on the side wall of the discharge component 2 away from the humidification cylinder 3. This can effectively draw the humidifying steam in the humidification cylinder 3 to the front wall of the discharge component 2. The temperature of the humidifying steam can be used to heat the front wall of the discharge component 2, reducing the temperature difference between the front wall of the discharge component 2 and the humidifying steam. As a result, the humidifying steam is less likely to condense into water droplets, and the moisture content of the tobacco leaves will be too high. At the same time, the humidifying steam inside the humidification cylinder 3 is discharged from the device through the first exhaust port 21 and the first air duct 42. This can effectively control the degree of humidification of the tobacco leaves and ensure product quality.

[0033] Preferably, such as Figure 2As shown, the exhaust assembly 4 also includes a second air duct 43, and the exhaust port also includes a second exhaust port 22. The second exhaust port 22 is opened on the side wall of the discharge part 2 near the humidification cylinder 3. The air inlet end of the second air duct 43 is connected to the second exhaust port, and the other end of the second air duct 43 is connected to the first air duct 42. By setting the second air duct 43 and the second exhaust port 22, the humidifying steam in the humidification cylinder 3 can be effectively drawn to the rear wall of the discharge part 2, so that the humidifying steam can be drawn from different directions, reducing the temperature difference between each wall of the discharge part 2 and the humidifying steam, making it less likely for the humidifying steam to condense into water droplets, and also improving the exhaust efficiency, ensuring smooth gas flow in the tobacco humidification device.

[0034] Preferably, such as Figure 1 As shown, the tobacco humidification device also includes a conveyor 5, which is located below the discharge port. The conveyor 5 can be a conveyor belt, a vibrating conveyor, or other conveying equipment. In this embodiment, the conveyor 5 is a conveyor belt. The conveyor 5 is used to transport the humidified tobacco leaves to the next production stage. The air extraction assembly 4 also includes a third air duct 44. Along the transmission direction of the conveyor 5, the air inlet end of the third air duct 44 covers the portion of the conveyor 5 located downstream of the discharge port. The other end of the third air duct 44 is connected to the first air duct 42. This design can extract excess moisture, odors, and dust generated during the transmission process, avoiding their impact on the working environment. It also helps to ensure the stability of the quality of the humidified tobacco leaves.

[0035] Preferably, the air inlet end of the third air duct 44 is tapered, gradually widening towards the duct opening. This design increases the air inlet area, allowing the air inlet end of the third air duct 44 to cover a larger area of ​​the tobacco leaves on the transmission component 5, thereby more effectively extracting excess moisture and dust from the humidified tobacco leaves.

[0036] Preferably, such as Figures 1-2 As shown, the extraction assembly 4 also includes a fan 41. The air inlet of the fan 41 is connected to the other end of the first duct 42 via a first pipe 45. The diameter of the first pipe 45 gradually increases from the first duct 42 towards the fan 41. This variable diameter design helps to reduce the gas flow velocity, reduce the impact of gas on the fan 41, and improve the working stability and service life of the fan 41. The air outlet of the fan 41 is connected to a second pipe 46. The diameter of the second pipe 46 gradually decreases from the fan 41 towards the direction away from the fan 41. This helps to increase the gas discharge pressure and ensures that the extracted gas can be smoothly discharged to the downstream processing equipment. At the same time, the variable diameter design of the first pipe 45 and the second pipe 46 also helps to increase the permeability of impurities such as dust in the extraction process. Compared with the case of sudden changes in pipe diameter, it can prevent impurities such as dust from being trapped in the pipeline of the extraction assembly 4.

[0037] Preferably, the tobacco humidification device further includes an adjustment component 421, which is disposed on the first air duct 42 and used to adjust the ventilation area inside the first air duct 42. The adjustment component 421 includes a lever 4211 and a baffle. The baffle is disposed inside the first air duct 42, and the lever 4211 is rotatably connected to the outer wall of the first air duct 42, with one end of the lever 4211 connected to the baffle. By rotating the lever 4211, the baffle can be moved within the first air duct 42, thereby changing the ventilation area of ​​the first air duct 42 and adjusting the air volume and velocity to adapt to different tobacco humidification process requirements.

[0038] Preferably, a filter element 211 is provided in the first exhaust port 21. The filter holes on the filter element 211 are of different diameters. The filter element 211 can effectively filter out impurities and small particles in the extracted gas, prevent them from entering the exhaust assembly 4, prevent impurities in the gas from being trapped in the system and causing damage to components such as the fan 41, and also avoid these impurities from polluting the environment.

[0039] Preferably, such as Figures 1-2 As shown, the air inlet end of the first air duct 42 has an arc-shaped cross section, and the air inlet end of the first air duct is covered by the first exhaust port 21. This semi-circular arc design can effectively increase the area of ​​the first exhaust port 21, and at the same time, it can better fit with the first exhaust port 21, thereby improving the air extraction efficiency.

[0040] The working process of the tobacco leaf humidification device provided by this utility model is as follows:

[0041] Tobacco leaves enter the device through the inlet of feeder 1. After humidification in humidification cylinder 3, the leaves enter discharge 2 and fall from the outlet of discharge 2 to conveyor 5 for transport to the next processing stage. The extraction assembly accelerates the flow of humidifying steam from humidification cylinder 3 into discharge 2 via first duct 42 and second duct 43. While extracting excess steam and dust, it also heats discharge 2, reducing the temperature difference between the inner wall of discharge 2 and the humidifying steam. This prevents the humidifying steam from condensing into water droplets, thus preventing excessive moisture content in the tobacco leaves and ensuring their quality. Furthermore, the third duct 46 further dehumidifies the tobacco leaves on conveyor 5, contributing to the stability of the humidified tobacco leaf quality. Operators can adjust the ventilation area of ​​the first air duct 42 by adjusting component 421 according to the actual production situation, and control the wind speed of the extraction component 4 to control the heating effect on the inner wall of the discharge part 2, ensure the temperature at the discharge end is stable, and reduce the generation of condensate and the adhesion of tobacco leaves.

[0042] Significant results have been achieved through practical application of the tobacco leaf humidification device of this utility model patent. In terms of tobacco leaf humidification, the gas environment during the humidification process is effectively controlled, reducing the problem of large deviations in tobacco leaf moisture content caused by water vapor accumulation, and improving the uniformity and quality stability of tobacco leaf humidification. Simultaneously, it further reduces the adhesion of wet tobacco leaves and contamination of materials, improving production efficiency and product quality. In summary, the tobacco leaf humidification device and anti-sticking system of this utility model patent have advantages such as reasonable structure, stable operation, and significant effects, and have broad application prospects and promotional value.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
