Description
Technical Field
[0001] This utility model relates to the field of tobacco machinery technology, specifically a multifunctional online air separation and impurity removal device for tobacco leaves. Background Technology
[0002] Tobacco leaf air separation, as a crucial process for removing light and heavy impurities from tobacco leaves and ensuring their purity, has always been a key step in the manufacturing process. Currently, light impurities are mainly removed using air separation equipment, while heavy impurities are mainly removed using roller screens. However, due to the thick layer of tobacco leaves entering the roller screen, impurities trapped within the leaves cannot pass through, often resulting in only the lower layer of leaves being screened, leading to poor screening efficiency. Simultaneously, the material passing through the screening rollers includes heavy impurities, broken tobacco leaves, tobacco leaves, and some light impurities, making subsequent sorting relatively difficult. Air separation is often used to separate broken tobacco leaves from the tobacco leaves, but it cannot completely separate impurities from the tobacco leaves. After screening, a large quantity of tobacco leaves is sent to the air separation equipment via auxiliary equipment for air separation, and impurities are manually removed from the separated small tobacco leaves and light impurities, making the process very difficult. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a multifunctional online tobacco leaf air separation and impurity removal device. By setting up a material distribution device, a pneumatic conveying device, a feeding device, an impurity removal device, and an air separation device on the frame assembly, it can separate light impurities, heavy objects, and tobacco leaves in one go, with high efficiency and perfect separation effect, solving the problems of insufficient separation effect and low efficiency of current devices.
[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0005] A multifunctional online tobacco leaf air separation and impurity removal device includes a frame assembly, and a feeding device, a pneumatic conveying device, a feeding device, an impurity removal device, and an air separation device respectively installed on the frame assembly. The pneumatic conveying device is a closed feeding frame fixed to the frame assembly. The feeding device is connected to one side of the pneumatic conveying device and includes a feeding hopper connected to one end of the feeding frame and a rotating rod rotatably connected to the top of the feeding hopper. An array of feeding fan blades is fixedly connected to the rotating rod. The feeding device is a feeding plate fixedly connected to the upper part of the feeding hopper. The impurity removal device is connected to the other side of the pneumatic conveying device. The device includes a debris sorting frame connected to the other end of the feeding frame, and a debris discharge port is provided at the bottom of the debris sorting frame; the air separation device is connected to the side of the debris removal device away from the pneumatic conveying device, and the air separation device includes an air separation box fixedly connected to the debris sorting frame. A baffle is fixed on one side of the air separation box, and a first baffle plate and a second baffle plate are fixedly connected to the inner side of the air separation box respectively. A curved plate is integrally formed on the side of the first baffle plate near the second baffle plate. A tobacco leaf channel is formed between the curved plate and the second baffle plate, and a heavy object discharge port is formed between the first baffle plate and the second baffle plate. A tobacco leaf discharge port is formed on one side of the first baffle plate, realizing one-time sorting and processing of debris, heavy objects and tobacco leaves.
[0006] Furthermore, protective side plates are fixedly connected to both sides of the rotating rod located on the feed fan blade plate.
[0007] Furthermore, the rotating rod and the feed fan blade rotate clockwise, thereby conveying the tobacco leaves on the cloth plate into the feed hopper.
[0008] Furthermore, it also includes a pneumatic conveying device, which includes an exhaust fan and two exhaust pipes connected to the exhaust fan outlet. One side of the pneumatic separation device is connected to a suction connector, and the end of one of the exhaust pipes is connected to the suction connector. The exhaust pipes and suction connector can deliver the pneumatic force to the debris removal device, thereby performing pneumatic separation.
[0009] Furthermore, the pneumatic conveying device also includes a booster compressor and a high-pressure pipe connected to the air outlet of the booster compressor. The end of another exhaust pipe is connected to the air inlet of the booster compressor. The end of the high-pressure pipe extends into the air classifier and forms an air nozzle. The air nozzle can blow away the tobacco leaves in the tobacco leaf passage and then blow them into one side of the first baffle plate, and discharge them through the tobacco leaf discharge port.
[0010] Furthermore, a wind hood is provided on the top of the feed hopper, and an air supply pipe is connected between the wind hood and the high-pressure pipeline.
[0011] Compared with the prior art, this utility model provides a multifunctional online air separation and impurity removal device for tobacco leaves, which has the following beneficial effects:
[0012] This utility model, by installing a cloth-laying device, a pneumatic conveying device, a feeding device, a debris removal device, and an air separation device on a frame assembly, has a reasonable and ingenious overall design. It can sort light debris, heavy objects, and tobacco leaves in one go, with high efficiency and excellent sorting effect. In use, the tobacco leaves are laid flat on the cloth-laying device and fed into the pneumatic conveying device through the feeding device. The pneumatic pressure transports the tobacco leaves to the debris removal device. When the tobacco leaves enter the debris removal device, because the tobacco leaves are laid flat, the air entering through the suction joint can blow away the surface lint and discharge it through the debris discharge port. The tobacco leaves and heavy objects are then separated. The material enters the air separation device and passes between the first and second baffle plates. At this time, the air force in the high-pressure pipeline blows out through the air nozzle and enters the space between the first and second baffle plates, allowing the tobacco leaves to be discharged through the tobacco leaf channel and enter the tobacco leaf discharge port on one side of the first baffle plate. Meanwhile, heavy objects (stones, metal, sand, etc.) are discharged through the heavy object discharge port. This achieves the air separation effect in tobacco leaf processing, which can separate light impurities (feathers, weeds, plastic film, etc.) and heavy objects (stones, metal, sand, etc.) in one go. The separation effect is excellent, which can improve efficiency and reduce labor and time costs. Attached Figure Description

Example
[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, an embodiment of the present invention proposes a multifunctional online tobacco leaf air separation and impurity removal device, including a frame assembly 2, and a feeding device 1, a pneumatic conveying device 3, a feeding device 24, an impurity removal device 10, and an air separation device 5 respectively installed on the frame assembly 2. The pneumatic conveying device 3 is a closed feeding frame fixed to the frame assembly 2; the feeding device 24 is connected to one side of the pneumatic conveying device 3, and includes a feeding hopper 14 connected to one end of the feeding frame, and a rotating rod 15 rotatably connected to the top of the feeding hopper 14, with an array of feeding fan blades 17 fixedly connected to the rotating rod 15; the feeding device 1 is a feeding plate fixedly connected to the upper part of the feeding hopper 14; the impurity removal device 10 is connected to the other side of the pneumatic conveying device 3. The debris removal device 10 includes a debris sorting frame connected to the other end of the feeding frame, and a debris discharge port 25 is provided at the bottom of the debris sorting frame; the air separation device 5 is connected to the side of the debris removal device 10 away from the air pressure conveying device 3. The air separation device 5 includes an air separation box fixedly connected to the debris sorting frame. A baffle 6 is fixed on one side of the air separation box, and a first baffle plate 20 and a second baffle plate 23 are fixedly connected to the inner side of the air separation box respectively. A curved plate 22 is integrally formed on the side of the first baffle plate 20 near the second baffle plate 23. A tobacco leaf channel is formed between the curved plate 22 and the second baffle plate 23, and a heavy object discharge port 19 is formed between the first baffle plate 20 and the second baffle plate 23. A tobacco leaf discharge port 21 is formed on one side of the first baffle plate 20, so as to realize the one-time sorting and processing of debris, heavy objects and tobacco leaves.
[0022] It should be noted that the frame assembly 2 is the overall support part of the device, where other components are installed. The spreading device 1 serves to spread and thin the tobacco leaves, effectively ensuring the air separation and impurity removal effect, and removing impurities. The feeding device 24 is connected between the spreading device 1 and the pneumatic conveying device 3, conveying the tobacco leaves into the pneumatic conveying device 3. The pneumatic conveying device 3 is powered by a motor belt conveyor and air force, conveying the tobacco leaves to the impurity removal device 10. When the tobacco leaves enter the impurity removal device 10, the impurities are identified and removed by the impurity removal device 10 and discharged into the impurity discharge port 25. Afterwards, the tobacco leaves enter the air separation device 5. By fixing the first baffle plate 20 and the second baffle plate 23 inside the air separation box, the tobacco leaves will enter between the first baffle plate 20 and the second baffle plate 23. Then, under the action of strong wind, the tobacco leaves can be discharged through the tobacco leaf channel between the curved plate 22 and the second baffle plate 23. Afterwards, the tobacco leaves are discharged through the tobacco leaf discharge port 21, and the heavy objects are discharged directly through the heavy object discharge port 19, thus separating the tobacco leaves and the heavy objects. The light and loose debris on the surface of the tobacco leaves can be removed through the exhaust pipe 8 and the suction connector 7. The feeding device 24 consists of the feeding hopper 14, the rotating rod 15, and the feeding fan blade 17, etc. The rotating rod 15 and the feed fan blade 17 can rotate clockwise, thereby conveying the tobacco leaves into the feed hopper 14, and then into the pneumatic conveying device 3. The pneumatic conveying device 3 is a closed feeding frame. When the tobacco leaves enter the pneumatic conveying device 3, they are conveyed by the wind to the impurity removal device 10. The main body of the impurity removal device 10 is an impurity sorting frame. When the tobacco leaves enter the impurity removal device 10, they can be sorted by the impurity removal device 10 to separate impurities, so that the impurities can be discharged through the impurity discharge port 25. The tobacco leaves then enter the air separation device 5. The main body of the air separation device 5 is the air separation box. By fixing the first baffle plate 20 and the second baffle plate 23 inside the air separation box, the tobacco leaves will enter between the first baffle plate 20 and the second baffle plate 23. Then, under the action of strong wind, the tobacco leaves can be discharged through the tobacco leaf channel between the curved plate 22 and the second baffle plate 23, and then discharged through the tobacco leaf discharge port 21. Heavy objects are discharged directly through the heavy object discharge port 19, which can be used for secondary sorting. This method has a good sorting effect and can sort light and fluffy debris, heavy objects, debris and tobacco leaves in one go, saving time and improving efficiency.
[0023] like Figure 2 As shown, in some embodiments, the rotating rod 15 is fixedly connected to protective side plates 16 on both sides of the feed fan blade plate 17.
[0024] It should be noted that the protective side plate 16 can protect the sides of the tobacco leaves and prevent them from falling off.
[0025] like Figure 1 and Figure 2As shown, in some embodiments, the rotating rod 15 and the feed fan blade 17 rotate clockwise, thereby conveying the tobacco leaves on the cloth plate into the feed hopper 14.
[0026] It should be noted that when the tobacco leaves approach the feed fan blade 17, the feed fan blade 17 rotates to achieve automatic feeding of the tobacco leaves.
[0027] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, a wind conveying device is also included. The wind conveying device includes an exhaust fan 9 and two exhaust pipes 8 connected to the air outlet of the exhaust fan 9. One side of the wind separation device 5 is connected to an air intake connector 7. The end of one of the exhaust pipes 8 is connected to the air intake connector 7. The other exhaust pipe 8 and the booster 11 can deliver the wind force to the debris removal device 10 for debris removal, and then perform wind separation of light and fluffy materials and heavy materials.
[0028] It should be noted that the air conveying device can realize the air separation of tobacco leaves. The exhaust fan 9 delivers the gas to the booster 11 through the exhaust pipe 8, and then through the high-pressure pipeline 12 and the air supply pipe 13 into the air pressure conveying device 3. After passing through the impurity removal device 10, the gas enters the interior of the air separation device 5. Another path goes through the high-pressure pipeline 12 to the air nozzle 4 to separate the light and fluffy particles, heavy objects and light and heavy impurities of the tobacco leaves by suction and blowing, thereby realizing the air separation and impurity removal function.
[0029] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the pneumatic conveying device further includes a booster compressor 11 and a high-pressure pipe 12 connected to the air outlet of the booster compressor 11. The end of another exhaust pipe 8 is connected to the air inlet of the booster compressor 11. The end of the high-pressure pipe 12 extends into the air separator 5 and forms an air nozzle 4. The air nozzle 4 can blow away the tobacco leaves in the tobacco leaf passage and then blow them into one side of the first baffle plate 20, and discharge them through the tobacco leaf discharge port 21.
[0030] It should be noted that the booster 11 can pressurize the gas. Its usage and principle are known existing technologies and will not be elaborated here. It can generate high-pressure gas and discharge it through the high-pressure pipe 12. The end of the high-pressure pipe 12 is connected to the air separator 5, which can generate a strong wind. The wind will blow the tobacco leaves between the first baffle plate 20 and the second baffle plate 23, so that the tobacco leaves are discharged through the tobacco leaf channel and heavy objects such as stones fall directly, realizing the air separation of tobacco leaves and heavy objects.
[0031] like Figure 1 and Figure 2As shown, in some embodiments, a hood 18 is provided on the top of the feed hopper 14, and an air supply pipe 13 is connected between the hood 18 and the high-pressure pipe 12.
[0032] It should be noted that the wind force enters the wind hood 18 through the air delivery pipe 13, and then blows the tobacco leaves in the feed hopper 14 to achieve the purpose of wind delivery.
[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
