Description

Technical Field

The inner surface of the drying chamber has a heating chamber. Both ends of the left side of the heating chamber are movably connected to rotating rods via bearings. The right end of the rotating rod is fixedly connected to a blower impeller, and the left end of the outer surface of the rotating rod is fixedly connected to a pulley.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] To address the technical problem that existing dryers cannot uniformly heat and dry the interior or bottom surfaces of tobacco, resulting in poor drying effects on the interior and bottom surfaces, this invention provides a drying device for tobacco processing. This device allows the feeding hopper 4 to add material to be dried into the inner cylinder 3. As the inner cylinder 3 continuously rotates relative to the heating cylinder 1, the material to be dried inside the inner cylinder 3 is constantly turned over, thereby achieving uniform heating and drying of the top, interior, and bottom surfaces of the material, facilitating the removal of moisture.

[0031] It should be noted that the tobacco drying device described in this utility model is used in, but not limited to, the field of tobacco processing technology. For ease of explanation, this utility model only uses the application of the tobacco drying device in the field of tobacco processing technology as an example for explanation. The principle of the tobacco drying device applied to other types of equipment is essentially the same as that applied to the field of tobacco processing technology, and will not be described in detail here.

[0032] Please see Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of a tobacco processing drying device according to an embodiment of the present invention. The tobacco processing drying device includes a heating cylinder 1, a discharge hopper 2, an inner cylinder 3, and a feeding hopper 4. The heating cylinder 1 is hollow inside, with one end open and the other end having a discharge hole connected to its interior. The discharge hopper 2 is connected to the heating cylinder 1 and is connected to the discharge hole. The inner cylinder 3 is hollow inside and has one end open. The open end of the inner cylinder 3 is inserted into the open end of the heating cylinder 1 and is connected to the discharge hole. The inner cylinder 3 can rotate relative to the heating cylinder 1. The feeding hopper 4 has a feeding end and a discharging end. The feeding end of the feeding hopper 4 is connected to the heating cylinder 1, and the discharging end is inserted into the interior of the inner cylinder 3 and can rotate relative to the inner cylinder 3.

[0033] In this device, one end of the heating cylinder 1 is open and the other end is provided with a discharge hole that communicates with its interior. The discharge hopper 2 is connected to the discharge hole. One end of the inner cylinder 3 is open and inserted into the open end of the heating cylinder 1. The inner cylinder 3 can rotate relative to the heating cylinder 1. The feed end of the feed hopper 4 is connected to the heating cylinder 1 and the discharge end is inserted into the interior of the inner cylinder 3. It can also rotate relative to the inner cylinder 3.

[0034] Compared to existing technologies, the new technology features an inner cylinder 3 structure that can rotate relative to the heating cylinder 1. The material to be dried is added to the inner cylinder 3 using the feed hopper 4. As the inner cylinder 3 rotates continuously relative to the heating cylinder 1, the material to be dried inside the inner cylinder 3 can be continuously turned over. This allows for uniform heating and drying of the top, interior, and bottom surfaces of the material, facilitating the removal of moisture. This solves the technical problem in existing technologies where the dryer cannot uniformly heat and dry the interior or bottom surfaces of tobacco, resulting in poor drying effects on the interior and bottom surfaces of tobacco.

The sealing plate 32 has a rotating hole. The rotating bearing 33 is fixedly sleeved on the discharge end of the feed hopper 4 and embedded in the rotating hole.

[0038] The discharge end of the feed hopper 4 is rotatably connected to the sealing plate 32 through a rotating bearing 33.

[0040] The baffle 34 is built into the material cylinder 31 to increase the contact area and contact time between the material to be dried and the material cylinder 31, thereby improving the drying effect.

[0041] In this embodiment, as Figure 1 , Figure 4 and Figure 5 As shown, the device also includes a base 5 and a drive unit 6, a dehumidification assembly 7, an exhaust assembly 8, and an interceptor 9.

[0042] The heating cylinder 1 is fixedly connected to the base 5. The driving component 6 includes a transmission gear sleeve 61, a driving gear 62, and a driving motor 63. The transmission gear sleeve 61 is fixedly sleeved on the circumferential outer wall of the material cylinder 31. The driving gear 62 can rotate relative to the base 5 and mesh with the transmission gear sleeve 61. The fixed end of the driving motor 63 is connected to the base 5, and the output shaft is connected to the driving gear 62. The driving motor 63 is used to drive the driving gear 62 to rotate around the output shaft of the driving motor 63 and mesh with the transmission gear sleeve 61.

[0043] Under the driving force of the drive motor 63, the drive gear 62 continuously meshes with the transmission sleeve 61, thereby driving the material cylinder 31 to rotate relative to the heating cylinder 1.

[0044] Furthermore, the drive motor 63 here is a common and readily available forward and reverse motor on the market, which is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0047] Furthermore, under the action of the first fan 72, the outside air enters the feed hopper 4 and the material cylinder 31 after being dehumidified by multiple dehumidification bars 73, ensuring that the material cylinder 31 has a dry air supply. The first fan 72 and the dehumidification bars 73 are common and readily available equipment on the market, and are conventional settings known to those skilled in the art, so they will not be described in detail here.

[0048] Furthermore, a filter mesh is also provided above the first fan 72, which will not be described in detail here.

[0049] In one embodiment, please refer to Figure 4 The dehumidification assembly 7 also includes an electric rotating shaft 74, which has a fixed end and a rotating end. The fixed end of the electric rotating shaft 74 is connected to the feed end of the feed hopper 4, and the rotating shaft is connected to the support frame 71. It is used to drive the support frame 71, the first fan 72 and the multiple dehumidification rods 73 to rotate relative to the feed end of the feed hopper 4, and to open or block the opening of the feed end of the feed hopper 4.

[0050] Under the action of the electric rotating shaft 74, the support frame 71 can rotate automatically relative to the feed hopper 4, thereby realizing the automatic opening or closing of the opening at the feed end of the feed hopper 4.

[0051] Furthermore, the electric rotating shaft 74 here is a common and readily available device on the market, and is a conventional setting known to those skilled in the art, so it will not be described in detail here.

[0052] In one embodiment, please refer to Figure 1 , Figure 4 The dehumidification component 7 also includes a fixing rod 75, one end of which is fixedly connected to the base 5 and the other end is connected to the feed hopper 4.

[0053] The fixing rod 75 provides support and connection for the feed hopper 4, positioning the feed hopper 4 above the top of the material cylinder 31, which facilitates material discharge.

[0054] In this embodiment, as Figure 5As shown, the other end of the heating cylinder 1 is also provided with an exhaust port. The exhaust assembly 8 includes an exhaust frame 81, a mesh 82, a filter screen 83 and at least one second fan 84. The exhaust frame 81 is connected to the heating cylinder 1 and communicates with the exhaust port. The exhaust frame 81 is funnel-shaped and the opening of the exhaust frame 81 gradually increases in the direction close to the heating cylinder 1. The mesh 82 is built into the exhaust frame 81 and is set opposite to the opening of the exhaust frame 81. The filter screen 83 is embedded in the exhaust port. At least one second fan 84 is set between the mesh 82 and the filter screen 83 and is connected to the exhaust frame 81.

[0055] The vent is designed to help discharge water vapor or waste gas generated inside the material cylinder 31, which is beneficial for drying the material.

[0056] Furthermore, the mesh 82 and the filter 83 securely mount at least one second fan 84 within the exhaust frame 81. Here, the filter 83 and the second fan 84 are common and readily available devices on the market, and are conventional setups known to those skilled in the art, so they will not be described in detail.

The side wall of the discharge hopper 2 has an opening that is connected to the interior of the discharge hopper 2. The tobacco processing drying device also includes an interceptor 9, which includes an interceptor net 91. The interceptor net 91 is slidably inserted into the opening, and the sliding direction of the interceptor net 91 is perpendicular to the discharge direction of the discharge hopper 2.

[0058] The interception net 91 is installed inside the discharge hopper to facilitate the blocking or discharge of materials.

[0059] In one embodiment, please refer to Figure 1 , Figure 2 The interceptor 9 also includes a limiting plate 92, which is connected to the interception net 91 and abuts against the outer wall of the discharge hopper 2.

[0061] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below:

[0062] The heating cylinder 1 has an open end and a discharge hole communicating with its interior at the other end. The discharge hopper 2 is connected to the discharge hole. The inner cylinder 3 has an open end and is inserted into the open end of the heating cylinder 1, and the inner cylinder 3 can rotate relative to the heating cylinder 1. The feed end of the feed hopper 4 is connected to the heating cylinder 1, and the discharge end is inserted into the interior of the inner cylinder 3, and it can rotate relative to the inner cylinder 3. Compared to existing technologies, this structure with a rotating inner cylinder 3 relative to the heating cylinder 1 allows for the addition of material to be dried into the inner cylinder 3 via the feed hopper 4. As the inner cylinder 3 continuously rotates relative to the heating cylinder 1, the material to be dried inside the inner cylinder 3 is constantly turned over, thus ensuring uniform heating and drying of the top, interior, and bottom surfaces of the material, facilitating the removal of moisture.

[0063] In the specific working process of this utility model, the user first drives the electric rotating shaft 74, causing the rotating end of the electric rotating shaft 74 to rotate relative to the fixed end, thereby driving the support frame 71 to rotate relative to the feeding hopper 4, thus opening the opening of the feeding end of the feeding hopper 4. Then, the material to be dried is put into the feeding end of the feeding hopper 4. After the dried material enters the material cylinder 31, the opening of the feeding end of the feeding hopper 4 is closed. Then, the drive motor 63 is started to drive the material cylinder 31 to rotate relative to the heating cylinder 1. During the drying process, the first fan 72 and the second fan 84 work simultaneously to ensure a continuous supply of fresh and dry air. Finally, after drying is completed, the intercepting net 91 is opened to remove the dried material from the material cylinder 31.

[0064] This device, through the aforementioned structure, can solve the technical problem in the prior art where existing dryers cannot uniformly heat and dry the interior or bottom surface of tobacco, resulting in poor drying effects on the interior and bottom of the tobacco.

[0065] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
