Description

Technical Field

[0001] The invention relates to the technical field of cigarette production, and in particular to a tobacco rehumidification and humidification system for residual cigarette processing. Background Art

[0002] The process of making tobacco leaves into cigarettes, including shredding and cigarette rolling, piping and packaging. In order to reduce the amount of tar in cigarettes, new technologies such as expanded shredded tobacco and perforated dilution are widely used in the cigarette making process. The cigarette making process varies according to the type of cigarette designed (flue-cured, blended, flavored). Since flue-cured tobacco accounts for more than 50% of the total tobacco production, the flue-cured tobacco type cigarette making process is the most common. If a processing step is added before shredding, it becomes a blended cigarette process.

[0003] The process of making tobacco leaves into shredded tobacco that meets the product tobacco flavor quality standards and is suitable for the cigarette rolling process requirements. Its task is to produce qualified shredded tobacco with high filling value with low tobacco leaf loss and energy consumption. The shredded tobacco making process mainly includes tobacco leaf blending, deformation processing (stem removal and shredding), moistening and drying, and adding materials and flavoring.

[0004] In the process of cigarette production, if there are unqualified or damaged cigarettes, it is usually necessary to open the wrapping paper, take out the tobacco and reprocess and package it. However, the tobacco in the cigarette is very dry. If the wrapping paper is opened directly, it is easy to cause the tobacco to break and crush. Therefore, before processing the remaining cigarettes, they need to be rehumidified to ensure the integrity of the tobacco. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a tobacco rehumidification and humidification system for residual cigarette processing, which solves the technical problem of tobacco breakage and crushing during residual cigarette processing.

[0007] (II) Technical solution

[0008] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0009] An embodiment of the present invention provides a tobacco rehumidification and humidification system for processing residual cigarettes, comprising an electric steam generator, a steam-water separation chamber connected to an air outlet end of the electric steam generator, a transport pipe connected to an air outlet end of the steam-water separation chamber, a rehumidification channel vertically arranged at one end of the transport pipe away from the steam-water separation chamber and connected to the transport pipe, a loading device arranged at one side of the rehumidification channel for adding residual cigarettes to the upper end of the rehumidification channel, and a unloading device arranged at the lower side of the rehumidification channel for receiving the residual cigarettes, the electric steam generator passes high-temperature steam into the steam-water separation chamber, the steam-water separation chamber intercepts visible small droplets in the high-temperature steam and passes humid air containing small molecular water into the transport pipe, the loading device transports the residual cigarettes to the top of the rehumidification channel, and the residual cigarettes fall freely inside the rehumidification channel and fall on the unloading device.

[0010] The embodiment of the present invention proposes a tobacco rehumidification and humidification system for processing residual cigarettes. Before the outer packaging of the residual cigarettes is crushed, the residual cigarettes are directly placed in a feeding device, and then the electric steam generator and the steam-water separation chamber are started. High-temperature steam is generated by the electric steam generator, and the high-temperature steam is directly introduced into the steam-water separation chamber. The high-temperature steam is separated into gas and liquid in the steam-water separation chamber, that is, small droplets in the steam are intercepted and gathered, and the invisible water molecules melted in the air are discharged from the steam-water separation chamber along the air, and the air containing a large amount of water vapor is discharged along the air pipe. The residual cigarettes are passed into the rehumidification channel. At this time, they enter along the opening at the upper end of the rehumidification channel under the transportation of the loading device, and then fall freely under the action of gravity. In the process of falling, they absorb water vapor in the air to complete the rehumidification, and finally fall into the unloading device along the opening at the lower end of the rehumidification channel. Then, they are transported to the subsequent residual cigarette outer packaging crushing process through the unloading device. This scheme allows the residual cigarettes to be rehumidified before being recycled, which can effectively reduce the chance of tobacco breakage and crushing. At the same time, the rehumidification process is continuous and uninterrupted, which is more efficient and convenient.

[0011] Optionally, the air transport pipe is split into multiple branch pipes at one end away from the steam-water separation chamber, the branch pipes are horizontal, and the multiple branch pipes are evenly spaced along the vertical direction. The end of the branch pipe away from the steam-water separation chamber is connected to the moisture return channel.

[0012] By splitting the end of the air transport pipe away from the steam-water separation chamber into multiple branch pipes, the multiple branch pipes are evenly arranged on one side of the rehumidification channel and connected to the rehumidification channel. When air containing a large amount of water vapor is introduced into the rehumidification channel through the air transport pipe, the multiple branch pipes can pass the air more quickly and evenly, so that during the continuous rehumidification of the residual cigarettes, the rehumidification channel can still maintain relatively uniform water vapor to ensure the rehumidification effect.

[0013] Optionally, the rehumidification channel is coaxially provided with annular air distribution channels evenly spaced from top to bottom, each of the branch pipes is connected to one of the air distribution channels, and the inner wall of the rehumidification channel is provided with multiple groups of jet holes evenly spaced from top to bottom, and each group of air holes is circumferentially arranged and connected to the same air distribution channel.

[0014] By opening a plurality of air distribution ring channels on the rehumidification channel, each branch pipe is connected to an air distribution ring channel. When the air pipeline is ventilated, each branch pipe will ventilate into the corresponding air distribution ring channel, and then spray out through the jet holes on the inner wall of the rehumidification channel, so that the water vapor in the air in the rehumidification channel is more uniform, thereby improving the rehumidification effect.

[0015] Optionally, the opening of the air jet holes away from one end of the air separation annular channel is inclined, and the air ejected from the same group of air jet holes forms a spiral air barrier in the rehumidification channel.

[0016] By setting the jet holes in an inclined shape, the air ejected from the same group of jet holes will form a spiral barrier in the rehumidification channel. On the one hand, the air flows in a spiral shape in the rehumidification channel, so that when the remaining cigarettes fall freely along the rehumidification channel, they will change in shape under the action of the air, making the fall more disorderly, thereby completing the rehumidification work more comprehensively. On the other hand, multiple air barriers are formed from top to bottom in the rehumidification channel, which can confine air containing a large amount of water vapor between adjacent air barriers, thereby increasing the water vapor content in the rehumidification channel, and thus better completing the rehumidification work.

[0017] Optionally, rotating rings are coaxially rotatably provided at the upper and lower ends of the rehumidification channel, and cyclone blades are evenly distributed on the inner wall of the rotating ring. The rotating rings at both ends drive the cyclone blades to rotate air into the rehumidification channel.

[0018] By arranging a rotating ring at the upper and lower ends of the rehumidification channel and arranging cyclone blades on the inner circle of the rotating ring, when the rotating ring rotates, the cyclone blades rotate synchronously, thereby swirling the air at both ends of the rehumidification channel into the rehumidification channel. On the one hand, the air containing a large amount of water vapor in the rehumidification channel can be restricted to reduce the probability of water vapor floating out along the two ends of the rehumidification channel. On the other hand, a certain pressure can be formed in the rehumidification channel, so that the water vapor can contact the remaining cigarette more quickly and complete the rehumidification, thereby improving the rehumidification efficiency.

[0019] Optionally, the feeding device includes a residual cigarette storage pool arranged on the ground, a conveyor belt whose lower end is obliquely inserted into the residual cigarette storage pool, and a feeding funnel arranged on the top of the conveyor belt and opening at the top of the rehumidification channel thereof. The bottom wall of the residual cigarette storage pool is arranged as an inclined sliding slope, and the outer peripheral end surface of the conveyor belt is provided with conveying support bars that drive the residual cigarettes to move obliquely upward, and the sliding slope allows the residual cigarettes to slide onto the conveying support bars of the conveyor belt under the action of gravity.

[0020] When the residual cigarettes are moved to the upper end of the rehumidification channel by the feeding device, the residual cigarettes are directly poured into the residual cigarette storage pool. Under the action of gravity, the residual cigarettes move along the sliding slope to the upper end surface of the contact conveyor belt. The conveyor belt works, and the conveying support bar takes the residual cigarettes away from the residual cigarette storage pool to the top of the conveyor belt. Then the residual cigarettes are directly poured into the feeding funnel, and finally enter the rehumidification channel directly under the guidance of the feeding funnel. This solution makes the feeding process of the residual cigarettes more convenient and faster.

[0021] Optionally, the feeding funnel is rotatably connected to the top of the conveyor belt, the rotation axis of the feeding funnel is vertical, and the inner circumferential wall of the feeding funnel is circumferentially evenly spaced with vertical partition baffles, and guide grooves for residual cigarettes to slide through are formed between adjacent partition baffles, and the inner circumferential wall of the feeding funnel is vertically provided with a guide cylinder for residual cigarettes to vertically pass through at the lower end of each guide groove.

[0022] By evenly arranging vertical partition baffles at circumferentially uniform intervals on the inner wall of the feeding funnel, guide grooves are formed between adjacent partition baffles. As the residual cigarettes continue to fall into the rotating feeding funnel, the residual cigarettes will enter the guide grooves one by one, thereby straightening the posture of the fallen residual cigarettes. Then, as the residual cigarettes pass through the guide cylinder, the residual cigarettes that enter the rehumidification channel from the feeding funnel are all in a vertical state, so that they can be more fully moistened to complete the rehumidification work.

[0023] Optionally, the unloading device includes an inclined vibrating conveyor and a moisturizing cover that covers the upper end of the vibrating conveyor, the moisturizing cover and the upper end of the vibrating conveyor form a movable long cavity for the movement of residual cigarettes, and a unloading hole is provided on the top of the moisturizing cover, which is aligned with the lower end opening of the rehumidification channel and connected to the movable long cavity, and one end of the branch pipe away from the steam-water separation bin is connected to the movable long cavity.

[0024] When the residual cigarettes after rehumidification are moved through the feeding device, the residual cigarettes directly enter the moving long cavity along the feeding hole, and then continue to move driven by the vibrating conveyor. One end of a branch pipe is directly connected to the moving long cavity, so that air containing a large amount of water vapor is directly introduced into the moving long cavity, and then the residual cigarettes are continuously rehumidified during the movement. On the one hand, the probability of residual cigarettes that have not been rehumidified can be reduced, and on the other hand, the rehumidification channel can be extended to improve the rehumidification effect.

[0025] Optionally, one end of the branch pipe away from the steam-water separation chamber is split into a plurality of capillaries, and the plurality of capillaries are horizontally evenly spaced and connected to both side ends of the moisturizing cover.

[0026] By splitting the branch tubes into capillaries and evenly distributing them at both ends of the moisturizing cover, when air containing a large amount of water vapor is introduced into the mobile long cavity through the branch tubes, the air can quickly and evenly fill the entire mobile long cavity, thereby further improving the moisture regaining effect.

[0027] Optionally, a water supply tank is disposed outside the electric steam generator, a condensation drain pipe is disposed outside the steam-water separation chamber, and the other end of the condensation drain pipe is connected to the water supply tank.

[0028] When the steam-water separation chamber separates the high-temperature steam, the small droplets visible in the steam will be condensed and gathered at the bottom and discharged through the condensation drain pipe. This solution directly connects one end of the condensation drain pipe to the water supply tank, so that the condensed and gathered water flow can enter the water supply tank to repeatedly generate electric steam, so as to improve the utilization rate of water resources and reduce the waste of water resources.

[0029] (III) Beneficial effects

[0030] The beneficial effects of the present invention are as follows: the tobacco rehumidification and humidification system for treating residual cigarettes of the present invention directly puts the residual cigarettes into the feeding device before crushing the outer packaging of the residual cigarettes, then starts the electric steam generator and the steam-water separation chamber, generates high-temperature steam through the electric steam generator, and directly passes the high-temperature steam into the steam-water separation chamber, where the high-temperature steam performs gas-liquid separation, that is, small droplets in the steam are intercepted and gathered, and the invisible water molecules melted in the air are discharged from the steam-water separation chamber along with the air, and the air containing a large amount of water vapor is discharged along the air flow. The pipeline leads into the rehumidification channel, and the remaining cigarettes enter along the opening at the upper end of the rehumidification channel under the transportation of the feeding device, and then fall freely under the action of gravity. In the process of falling, they absorb water vapor in the air to complete the rehumidification, and finally fall into the unloading device along the opening at the lower end of the rehumidification channel, and then are transported to the subsequent remaining cigarette outer packaging crushing process through the unloading device. This scheme allows the remaining cigarettes to be rehumidified before recycling, which can effectively reduce the chance of tobacco breakage and crushing. At the same time, the rehumidification process is continuous and uninterrupted, which is more efficient and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0037] The tobacco rehumidification and humidification system for treating residual cigarettes proposed in the embodiment of the present invention directly puts the residual cigarettes into the feeding device before crushing the outer packaging of the residual cigarettes, then starts the electric steam generator and the steam-water separation chamber, generates high-temperature steam through the electric steam generator, and directly passes the high-temperature steam into the steam-water separation chamber, where the high-temperature steam performs gas-liquid separation, that is, small droplets in the steam are intercepted and gathered, and the invisible water molecules melted in the air are discharged from the steam-water separation chamber along with the air, and the air containing a large amount of water vapor passes along the air pipe. The residual cigarettes enter the rehumidification channel. At this time, the residual cigarettes enter along the opening at the upper end of the rehumidification channel under the transportation of the feeding device, and then fall freely under the action of gravity. In the process of falling, they absorb water vapor in the air to complete the rehumidification, and finally fall into the unloading device along the opening at the lower end of the rehumidification channel. Then, they are transported to the subsequent residual cigarette outer packaging crushing process through the unloading device. This scheme allows the residual cigarettes to be rehumidified before they are recycled, which can effectively reduce the probability of tobacco breakage and crushing. At the same time, the rehumidification process is continuous and uninterrupted, which is more efficient and convenient.

[0038] In order to better understand the above technical solution, 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 accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0039] Reference Figure 1 and Figure 2 A tobacco rehumidification and humidification system for processing residual cigarettes comprises an electric steam generator 1, a steam-water separation chamber 2 connected to an air outlet end of the electric steam generator 1, a transport pipe 3 connected to an air outlet end of the steam-water separation chamber 2, a rehumidification channel 4 vertically arranged at one end of the transport pipe 3 away from the steam-water separation chamber 2 and connected to the transport pipe 3, a feeding device 5 arranged at one side of the rehumidification channel 4 for adding residual cigarettes to the upper end of the rehumidification channel 4, and a unloading device 6 arranged at the lower side of the rehumidification channel 4 for receiving the residual cigarettes.

[0040] The remaining cigarettes are directly placed into the feeding device 5, and then the electric steam generator 1 and the steam-water separation chamber 2 are started. High-temperature steam is generated by the electric steam generator 1, and the high-temperature steam is directly passed into the steam-water separation chamber 2. The high-temperature steam is separated into gas and liquid in the steam-water separation chamber 2, that is, the small droplets in the steam are intercepted and gathered, and the invisible water molecules dissolved in the air are discharged from the steam-water separation chamber 2 along the air, and the air containing a large amount of water vapor is passed into the rehumidification channel 4 along the air transport pipe 3. At this time, the remaining cigarettes enter along the opening at the upper end of the rehumidification channel 4 under the transportation of the feeding device 5, and then fall freely under the action of gravity. In the process of falling, they absorb water vapor in the air, thereby completing rehumidification, and finally fall into the unloading device 6 along the opening at the lower end of the rehumidification channel 4, and then are transported to the subsequent residual cigarette outer packaging crushing process through the unloading device 6.

[0041] A water supply tank 11 is provided outside the electric steam generator 1, and a condensation drain pipe 21 is provided outside the steam-water separation chamber 2, and the other end of the condensation drain pipe 21 is connected to the water supply tank 11. When the steam-water separation chamber 2 separates the high-temperature steam, the small droplets visible in the steam will be condensed and gathered at the bottom and discharged through the condensation drain pipe 21, and the condensed and gathered water flow can enter the water supply tank 11 to repeat the electric steam generation, so as to improve the utilization rate of water resources and reduce the waste of water resources.

[0042] See also Figure 2 and Figure 3The end of the air transport pipe 3 away from the steam-water separation chamber 2 is split into multiple branch pipes 31, and the branch pipes 31 are horizontal. The multiple branch pipes 31 are evenly spaced in the vertical direction. The end of the branch pipe 31 away from the steam-water separation chamber 2 is connected to the rehumidification channel 4. The rehumidification channel 4 is evenly spaced from top to bottom and coaxially provided with annular air distribution channels 41. Each branch pipe 31 is connected to an air distribution channel 41. The inner wall of the rehumidification channel 4 is evenly spaced from top to bottom and multiple groups of air jet holes 42 are evenly spaced from top to bottom. Each group of air holes is arranged circumferentially and connected to the same air distribution channel 41. The opening of the air jet hole 42 away from the end of the air distribution channel 41 is inclined, and the air ejected from the same group of air jet holes 42 forms a spiral air barrier in the rehumidification channel 4. When air containing a large amount of water vapor is introduced into the rehumidification channel 4 through the air supply pipe 3, the multiple branch pipes 31 can introduce air more quickly and evenly, so that during the continuous rehumidification of the residual cigarettes, the rehumidification channel 4 can still maintain relatively uniform water vapor to ensure the rehumidification effect. Each branch pipe 31 will ventilate the corresponding air distribution ring channel 41, and then spray it out through the jet holes 42 on the inner wall of the rehumidification channel 4, so that the water vapor in the air in the rehumidification channel 4 is more uniform, thereby improving the rehumidification effect. The jet holes 42 are set in an inclined shape so that the same group of The air ejected from the jet hole 42 will form a spiral barrier in the rehumidification channel 4. On the one hand, the air flows in a spiral shape in the rehumidification channel 4, so that when the remaining cigarettes fall freely along the rehumidification channel 4, their shapes will change under the action of the air, making the fall more disorderly, thereby completing the rehumidification work more comprehensively. On the other hand, multiple air barriers are formed from top to bottom in the rehumidification channel 4, which can limit the air containing a large amount of water vapor between adjacent air barriers, thereby increasing the water vapor content in the rehumidification channel 4, and thus better completing the rehumidification work.

[0043] The upper and lower ends of the rehumidification channel 4 are coaxially rotatably connected with a rotating ring 43 through a bearing, and the inner wall of the rotating ring 43 is evenly spaced with cyclone blades 44. The rotating rings 43 at both ends drive the cyclone blades 44 to rotate air into the rehumidification channel 4. When the rotating ring 43 rotates, the cyclone blades 44 rotate synchronously, so as to rotate the air at both ends of the rehumidification channel 4 into the rehumidification channel 4. On the one hand, the air containing a large amount of water vapor in the rehumidification channel 4 can be restricted to reduce the probability of water vapor floating out along the two ends of the rehumidification channel 4. On the other hand, a certain pressure can be formed in the rehumidification channel 4, so that the water vapor can contact the residual cigarette more quickly and complete the rehumidification.

[0044] The feeding device 5 comprises a residual cigarette storage pool 51 arranged on the ground, a conveyor belt 52 with its lower end obliquely inserted into the residual cigarette storage pool 51, and a feeding funnel 53 arranged on the top of the conveyor belt 52 and opened at the top of the rehumidification channel 4. The bottom wall of the residual cigarette storage pool 51 is arranged as a sliding slope 511 in an inclined state. The outer peripheral end surface of the conveyor belt 52 is evenly spaced in the circumferential direction to drive the residual cigarettes to move upward obliquely. The sliding slope 511 allows the residual cigarettes to slide down under the action of gravity. Move to the conveying support bar 521 of the conveyor belt 52, and the loading funnel 53 is connected to the top of the conveyor belt 52 by being driven to rotate by a motor. The rotation axis of the loading funnel 53 is vertical, and the inner wall of the loading funnel 53 is welded with vertical partition baffles 531 at uniform intervals in the circumferential direction, and guide grooves 532 for residual cigarettes to slide through are formed between adjacent partition baffles 531. The inner wall of the loading funnel 53 is vertically welded with a guide cylinder 533 for residual cigarettes to pass vertically at the lower end of each guide groove 532. The residual cigarettes are directly poured into the residual cigarette storage pool 51. Under the action of gravity, the residual cigarettes move along the sliding slope 511 to the upper end surface of the contact conveyor belt 52. The conveyor belt 52 works, and the conveying support bar 521 brings the residual cigarettes away from the residual cigarette storage pool 51 to the top of the conveyor belt 52. Then the residual cigarettes are directly poured into the feeding funnel 53. As the residual cigarettes continue to fall into the rotating feeding funnel 53, the residual cigarettes will continuously enter the guide chute 532 in turn, so as to straighten the posture of the fallen residual cigarettes. Then, as the residual cigarettes pass through the guide cylinder 533, the residual cigarettes entering the rehumidification channel 4 from the feeding funnel 53 are all in a vertical state, so that they can be more comprehensively moistened to complete the rehumidification work.

[0045] The unloading device 6 includes an inclined vibrating conveyor 62 and a moisturizing cover 61 fixed to the upper end of the vibrating conveyor 62 by bolts. The moisturizing cover 61 and the upper end of the vibrating conveyor 62 form a movable long cavity 63 for the movement of residual cigarettes. The top of the moisturizing cover 61 is provided with a unloading hole 611 aligned with the lower end opening of the rehumidification channel 4 and connected to the movable long cavity 63. One end of a branch pipe 31 away from the steam-water separation chamber 2 is connected to the movable long cavity 63. The end of the branch pipe 31 away from the steam-water separation chamber 2 is split into multiple capillaries 32, and the multiple capillaries 32 are horizontally evenly spaced and connected to the two side ends of the moisturizing cover 61. The residual cigarettes directly enter the movable long cavity 63 along the discharge hole 611, and then continue to move driven by the vibrating conveyor 62. Air containing a large amount of water vapor is introduced into the movable long cavity 63 through the branch tube 31, and then the residual cigarettes are continuously rehumidified during the movement. On the one hand, the probability of residual cigarettes that have not been rehumidified can be reduced. On the other hand, the rehumidification channel 4 can be extended to improve the rehumidification effect. At the same time, the branch tube 31 is split into capillaries 32 and evenly spaced at both sides of the moisturizing cover 61, so that when air containing a large amount of water vapor is introduced into the movable long cavity 63 through the branch tube 31, the air can quickly and evenly fill the entire movable long cavity 63, thereby further improving the rehumidification effect.
