Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, and in particular to a device for separating moisture from tobacco leaves after processing residual cigarettes. Background Technology

[0002] The process of turning tobacco leaves into cigarettes includes tobacco processing, cigarette rolling, tapping, and packaging. To reduce the tar content in cigarettes, new technologies such as expanded tobacco and perforated dilution are widely used in the cigarette-making process. The cigarette-making process varies depending on the type of cigarette designed (flue-cured, blended, or flavored). Since flue-cured tobacco accounts for more than 50% of the total tobacco production, flue-cured cigarette making is the most common. If an additional processing step is added before shredding, it becomes a blended cigarette making process.

[0003] The process of processing tobacco leaves into shredded tobacco that meets the quality standards for tobacco aroma and flavor and is suitable for cigarette rolling. Its goal is to produce qualified shredded tobacco with high filling value while minimizing tobacco leaf loss and energy consumption. The shredding process mainly includes tobacco blending, texturing (destemming and shredding), moistening and drying, and adding flavorings and aromatics.

[0004] In the cigarette production process, if cigarettes fail inspection or are damaged, the packaging paper usually needs to be opened to remove the tobacco and repackage them. However, the tobacco inside the cigarette is quite dry. If the packaging paper is opened directly, it is easy to cause the tobacco to break and crumble. Therefore, it is necessary to rehydrate and moisten the cigarettes before processing the remaining cigarettes to ensure the integrity of the tobacco.

[0005] When rehydrating cigarette residue, the vapor-water separation device is crucial to ensuring that the cigarette residue is not soaked while rehydrating. The key to ensuring rehydration is to separate visible droplets in the vapor and allow only air containing small water molecules to pass through. Maximizing the effect of vapor-water separation is the key to rehydrating cigarette residue. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides a device for separating moisture from water in the tobacco shreds used for treating residual cigarettes, which solves the technical problem of poor water-vapor separation effect.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0010] This utility model provides a device for separating moisture from tobacco residue in the treatment of cigarette residue, comprising a horizontally arranged separation shell, a cyclone separation component, a corrugated plate separation component, and a wire mesh separation component disposed inside the separation shell. The two ends of the separation shell are an air inlet and an air outlet, respectively. The cyclone separation component, the corrugated plate separation component, and the wire mesh separation component are arranged sequentially from the air inlet to the air outlet. A vortex separation chamber is formed between the cyclone separation component and the corrugated plate separation component. The separation shell has multiple concentric rings coaxially arranged on the inner peripheral wall of the vortex separation chamber. The multiple concentric rings are evenly spaced along the length of the vortex separation chamber. The cross-section of the concentric rings is "L"-shaped. The concentric rings and the inner wall of the separation shell form a concentric ring groove with an opening facing the cyclone separation component. The lower end of the separation shell has multiple downflow holes communicating with each of the concentric ring grooves. The lower end of the separation shell has a drain pipe communicating with each of the downflow holes.

[0011] This utility model proposes a device for separating the moisture from the rehydrated tobacco shreds in the treatment of residual cigarettes. When high-temperature steam is separated into moisture using this device, the high-temperature steam is directly introduced through the air inlet at one end of the separation shell. Under the action of the cyclone separation component, the high-temperature steam is quickly drawn in and thrown to the inner wall of the cyclone separation chamber. At this time, small droplets in the steam will adhere to the inner wall of the cyclone separation chamber. Simultaneously, under the action of air blowing, they will flow into the intercepting ring groove. Multiple intercepting ring grooves can effectively intercept and collect the small droplets, and finally flow out along the downflow hole and then be discharged through the drain pipe. This solution can effectively reduce the probability that the high-speed air passing through during the steam-water separation process will carry small droplets out along the air outlet again, thereby improving the steam-water separation effect.

[0012] Optionally, the cyclone separation assembly includes a diffuser sleeve coaxial with the separation housing and a cyclone impeller rotatably disposed coaxially with the diffuser sleeve. One end of the diffuser sleeve is connected to the air inlet of the separation housing. The diffuser sleeve is flared from one end near the air inlet to the other end. The cyclone impeller is disposed at the maximum diameter of the diffuser sleeve.

[0013] By setting the cyclone separator assembly as a diffuser sleeve and a cyclone impeller, the diffuser sleeve is flared from the air inlet side to the inside. Combined with the cyclone impeller located at the maximum diameter, when the cyclone impeller rotates, it can diffuse and throw the high-temperature steam outward in conjunction with the introduction of high-temperature steam, thereby further improving the steam-water separation effect.

[0014] Optionally, the wave plate separation assembly includes multiple wave plates evenly spaced inside the separation housing, the wave plates being arranged vertically, and gaps being formed between adjacent wave plates to allow air to pass through.

[0015] By setting the corrugated plate separation component as multiple corrugated plates arranged at even intervals, gaps are formed between adjacent corrugated plates. When the high-temperature steam undergoes the first water vapor separation at the cyclone separation component, the water vapor will pass through the corrugated plate separation component. The gaps between adjacent corrugated plates are continuously bent, which intercepts the passing water vapor. That is, the small droplets remaining in the water vapor will adhere to the surface of the corrugated plate, thereby improving the water vapor separation effect.

[0016] Optionally, the wave plate separation assembly further includes a first rotating ring coaxially rotatably embedded in the inner wall of the separation housing. Both ends of each wave plate are fixed to the inner wall of the first rotating ring and rotate with the first rotating ring. The inner wall of the separation housing is coaxially provided with a flow-blocking convex ring between the wave plate separation assembly and the wire mesh separation assembly and has the flow-down hole.

[0017] The first rotating ring drives all the corrugated plates to rotate together, so that when water vapor passes through the corrugated plate separation assembly, it can come into more full contact with the surface of the corrugated plates, thereby more fully trapping the small droplets in the water vapor and improving the water vapor separation effect. The trapped small droplets will also be thrown along the surface of the corrugated plates to the inner wall of the separation shell and finally flow into the downstream hole.

[0018] Optionally, the wire mesh separation assembly includes a second rotating ring coaxially rotatably disposed on the inner wall of the separation housing and a wire mesh sheet coaxially fixed to the inner peripheral wall of the second rotating ring. The inner wall of the separation housing is coaxially disposed with a flow-blocking convex ring on the side of the wire mesh separation assembly away from the corrugated plate separation assembly and has the flow-down hole.

[0019] By setting up wire mesh and driving it to rotate via a second rotating ring, water vapor carrying small droplets is trapped as it passes through multiple sets of wire mesh, thereby improving the water vapor separation effect.

[0020] Optionally, the wire mesh is provided in multiple pieces and is evenly spaced along the length of the separation shell. The inner peripheral wall of the second rotating ring is evenly spaced with connecting strips extending along the length of the separation shell, and the multiple pieces of wire mesh are fixed to the connecting strips.

[0021] By setting multiple steel wire mesh sheets, connecting them into a whole through connecting strips, and driving them to rotate synchronously through a second rotating ring, the interception effect of small droplets is improved, thereby further enhancing the water vapor separation effect.

[0022] Optionally, the wire mesh is provided in multiple pieces, and all the wire mesh pieces are rotatably disposed on the inner wall of the separation shell, with adjacent wire mesh pieces rotating in opposite directions.

[0023] By setting multiple wire mesh panels with adjacent panels rotating in opposite directions, water vapor encounters greater difficulty in passing through the entire wire mesh separation assembly, resulting in better interception of small droplets and further improving the water vapor separation effect.

[0024] Optionally, a temperature-regulating box is fitted outside the separation shell, and a temperature-regulating cavity is formed between the temperature-regulating box and the separation shell. The temperature-regulating cavity is filled with heat-insulating gas to stabilize the temperature of the separation shell.

[0025] By installing a temperature-regulating box outside the separation shell, a temperature-regulating cavity is formed between the temperature-regulating box and the separation shell. By injecting heat-insulating gas into the temperature-regulating cavity, the temperature of the separation shell can be maintained. Thus, when separating the high-temperature steam introduced into the separation shell, both the separation effect and the moisture content of the discharged gas must be ensured, thereby improving the steam-water separation effect.

[0026] (III) Beneficial Effects

[0027] The beneficial effects of this utility model are as follows: When the residual cigarette cigarette processing tobacco re-moistening steam-water separation device of this utility model separates high-temperature steam into water, the high-temperature steam is directly introduced through the air inlet at one end of the separation shell. Under the action of the cyclone separation component, the high-temperature steam is quickly drawn in and thrown to the inner wall of the cyclone separation chamber. At this time, the small droplets in the steam will adhere to the inner wall of the cyclone separation chamber. At the same time, under the action of air blowing, they will flow into the intercepting ring groove. The multiple intercepting ring grooves can effectively intercept and collect the small droplets, and finally flow out along the downflow hole and then be discharged through the drain pipe. This scheme can effectively reduce the probability that the high-speed air passing through during the steam-water separation process will carry the small droplets out along the air outlet again, thereby improving the steam-water separation effect.

[0032] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] The residual tobacco processing and moisture separation device proposed in this embodiment of the invention separates high-temperature steam into water. When the device separates high-temperature steam into water, the high-temperature steam is directly introduced through the air inlet at one end of the separation shell. Under the action of the cyclone separation component, the high-temperature steam is quickly drawn in and thrown to the inner wall of the cyclone separation chamber. At this time, small droplets in the steam will adhere to the inner wall of the cyclone separation chamber. At the same time, under the action of air blowing, they will flow into the intercepting ring groove. Multiple intercepting ring grooves can effectively intercept and collect small droplets, and finally flow out along the downflow hole and then be discharged through the drain pipe. This solution can effectively reduce the probability that the high-speed air passing through during the steam-water separation process will carry small droplets out along the air outlet again, thereby improving the steam-water separation effect.

[0034] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0035] Example 1,

[0036] Reference Figure 1 A device for separating moisture from tobacco shreds in the treatment of residual cigarettes includes a horizontally arranged separation shell 1, a cyclone separation component 2, a corrugated plate separation component 3, and a wire mesh separation component 4 disposed inside the separation shell 1. The two ends of the separation shell 1 are an air inlet 11 and an air outlet 12, respectively. The cyclone separation component 2, the corrugated plate separation component 3, and the wire mesh separation component 4 are arranged sequentially from the air inlet 11 to the air outlet 12.

[0037] A cyclone separation chamber 13 is formed inside the separation housing 1 between the cyclone separation assembly 2 and the corrugated plate separation assembly 3. The cyclone separation assembly 2 includes a diffuser sleeve 21 coaxially integrally formed with the separation housing 1 and a cyclone impeller 22 coaxially rotatably disposed on the diffuser sleeve 21. One end of the diffuser sleeve 21 is connected to the air inlet 11 of the separation housing 1. The diffuser sleeve 21 is flared from one end near the air inlet 11 to the other end. The cyclone impeller 22 is fixed to the maximum diameter of the diffuser sleeve 21 by bolts. Multiple flow-blocking protrusions 14 are coaxially welded to the inner peripheral wall of the cyclone separation chamber 13. The multiple flow-blocking protrusions 14 are evenly spaced along the length of the cyclone separation chamber 13. The cross-section of the flow-blocking protrusions 14 is "L" shaped. The flow-blocking protrusions 14 and the inner wall of the separation housing 1 form a flow-blocking annular groove 15 with the opening facing the cyclone separation component 2. Multiple flow holes 16 connected to each flow-blocking annular groove 15 are opened at the lower end of the separation housing 1. A drain pipe 17 connected to each flow hole 16 is welded to the lower end of the separation housing 1. When the cyclone impeller 22 rotates, it can be combined with the introduction of high-temperature steam to achieve the effect of diffusion and outward throwing of high-temperature steam. The high-temperature steam is quickly drawn in and thrown to the inner wall of the cyclone separation chamber 13. At this time, the small droplets in the steam will adhere to the inner wall of the cyclone separation chamber 13. At the same time, under the action of air blowing, they will flow into the intercepting ring groove 15. The multiple ring grooves 15 can effectively intercept and collect the small droplets, and finally flow out along the downflow hole 16, and then be discharged through the drain pipe 17.

[0038] The corrugated plate separation assembly 3 includes a first rotating ring 31 coaxially rotatably embedded in the inner wall of the separation housing 1 and multiple corrugated plates 32 evenly spaced inside the separation housing 1. The multiple corrugated plates 32 are arranged in parallel, and the length direction of the corrugated plates 32 is the length direction of the separation housing 1. A gap is formed between adjacent corrugated plates 32 to allow air to pass through. Both ends of each corrugated plate 32 are welded and fixed to the inner wall of the first rotating ring 31 and rotate with the first rotating ring 31. A flow-blocking convex ring 14 is coaxially welded between the corrugated plate separation assembly 3 and the wire mesh separation assembly 4 on the inner wall of the separation housing 1 and a flow-down hole 16 is provided. After the high-temperature steam undergoes the first water vapor separation at the cyclone separator 2, the water vapor will pass through the corrugated plate separator 3. The gap between adjacent corrugated plates 32 is continuously bent, which intercepts the passing water vapor. That is, the small droplets remaining in the water vapor will adhere to the surface of the corrugated plate 32. At the same time, the first rotating ring 31 drives all the corrugated plates 32 to rotate together, so that the water vapor can contact the surface of the corrugated plate 32 more fully when passing through the corrugated plate separator 3. The intercepted small droplets will also be thrown along the surface of the corrugated plate 32 to the inner wall of the separator housing 1 and finally flow into the downflow hole 16.

[0039] The wire mesh separation assembly 4 includes a second rotating ring 41 coaxially rotatably mounted on the inner wall of the separation housing 1, and wire mesh sheets 42 coaxially welded and fixed to the inner circumferential wall of the second rotating ring 41. A flow-blocking convex ring 14 is coaxially arranged on the side of the inner wall of the separation housing 1 away from the corrugated plate separation assembly 3, and a flow-down hole 16 is provided. Multiple wire mesh sheets 42 are arranged at even intervals along the length of the separation housing 1. Connecting strips 411 extending along the length of the separation housing 1 are welded at even intervals to the inner circumferential wall of the second rotating ring 41, and the multiple wire mesh sheets 42 are welded to the connecting strips 411. The second rotating ring 41 drives the multiple wire mesh sheets 42 to rotate, thereby improving the interception effect of small droplets in water vapor.

[0040] A temperature-regulating chamber 5 is fitted outside the separation shell 1, forming a temperature-regulating cavity 51 between the temperature-regulating chamber 5 and the separation shell 1. The temperature-regulating cavity 51 is filled with heat-insulating gas to stabilize the temperature of the separation shell 1. By injecting heat-insulating gas into the temperature-regulating cavity 51, the temperature of the separation shell 1 can be maintained, thus ensuring both the separation effect and the moisture content of the discharged gas when performing steam-water separation on the high-temperature steam introduced into the separation shell 1.

[0041] Example 2,

[0042] Reference Figure 1 and 2 The difference from Embodiment 1 is that the second rotating ring 41 has multiple rings, which are evenly spaced along the length of the separation housing 1. Similarly, multiple wire mesh sheets 42 are also provided and fixed to each of the second rotating rings 41. Driven by the second rotating rings 41, adjacent wire mesh sheets 42 rotate in opposite directions. This makes it more difficult for water vapor to pass through the entire wire mesh separation assembly 4, resulting in better interception of small droplets and further improving the water vapor separation effect.
