Description

TECHNICAL FIELD

[0002] Reconstituted tobacco refers to a regenerated product in the form of sheet or filament made of waste tobacco stems, tobacco fines and tobacco fragments in the process of cigarette processing, which is used as a cigarette filler. Reconstituted tobacco plays an important role in cigarette production, which not only can reduce the cost of cigarettes, but also can improve the internal quality of cigarettes.

[0024] As Figure 1As shown, the reconstituted tobacco dust utilization system provided by the embodiment of the application comprises a dust collector 1, a dust receiving box 2, a conveying device, a pulp production device, a mixing device 8 and a spraying device 9. The dust collector 1 is communicated with the dust receiving box 2 to convey the dust to the dust receiving box 2. The dust receiving box 2 is communicated with the pulp production device and the mixing device 8 respectively through the conveying device. The spraying device 9 is communicated with the pulp production device and the mixing device 8 respectively.

[0025] It can be understood that the conveying device can be one or two. That is, the dust receiving box 2 can be communicated with the pulp production device and the mixing device 8 respectively through the same conveying device, or can be communicated with the two through different conveying devices respectively. The pulp production device is used to prepare pulp for spraying fiber paper from the reutilized dust, and the fiber paper is used to prepare tobacco paper after being sprayed with the pulp. The mixing device 8 is used to mix the dust with water to prepare spraying liquid, which is sprayed on the tobacco paper to fill the uneven places on the surface of the tobacco paper and make the pulp coating on the surface more uniform.

[0026] The reconstituted tobacco dust utilization system of the embodiment of the application is provided with the mixing device 8 and the pulp production device communicated with the dust receiving box 2. The dust is mixed with water in the mixing device 8 to obtain spraying liquid and is mixed with raw materials of pulp in the pulp production device to obtain pulp. That is, the dust can be converted into useful mixed liquid respectively, and then the pulp and the spraying liquid are conveyed into the spraying device 9 in sequence. The pulp is coated on the fiber paper to obtain tobacco paper, and the spraying liquid is sprayed on the tobacco paper to fill the uneven places on the tobacco paper. In this way, the dust can be fully treated and utilized, and the technical problems of dust diffusion in the reconstituted tobacco production site and blockage of the conveying pipeline 5 are avoided.

[0027] In some embodiments, the conveying device comprises a conveying pipeline 5, a weight monitoring meter 6, a control system and a valve 7. The weight monitoring meter 6 is installed on the dust receiving box 2 to monitor the weight of the dust in the dust receiving box 2. The weight monitoring meter 6 is connected with the control system to transmit a weight signal to the control system. The control system is connected with the valve 7 to control the opening and closing of the valve 7. The dust receiving box 2 is communicated with the conveying pipeline 5 through the valve 7, and the conveying pipeline 5 is communicated with the pulp production device or the mixing device 8.

[0028] In the embodiment of the application, the weight monitoring meter 6 is installed at the bottom of the dust receiving box 2 to monitor the weight of the dust in the dust receiving box 2. When the weight of the dust is lower than a certain threshold value, a signal is sent to the control system to control the valve 7 to be closed. In this way, the amount of the dust in the dust receiving box 2 entering the mixing device 8 and the pulp production device can be controlled. The dust receiving box 2 is communicated with the conveying pipeline 5 through the valve 7, so that the amount of the dust in the dust receiving box 2 entering the conveying pipeline 5 can be controlled.

[0029] In the embodiment of the present application, the weight monitoring meter, the control system and the valve are one, and other valves can be arranged between the conveying pipeline 5 and the slurry production device and the mixing device 8. When it is needed to convey the dust to the slurry production device, the valve between the conveying pipeline 5 and the slurry production device is opened to make the two communicate. When it is needed to convey the dust to the mixing device 8, the valve between the conveying pipeline 5 and the mixing device 8 is opened to make the two communicate.

[0030] In other embodiments, the number of conveying devices is two, one conveying device is connected to the ash box 2 and the slurry production device, and the other conveying device is connected to the ash box 2 and the mixing device 8. That is, two weight monitoring meters 6, two valves 7 and two control systems can be arranged similarly. In this case, the two valves 7 can be set to different opening and closing thresholds, so that when the threshold requirements of the mixing device 8 and the slurry production device for the dust are different, the conveying of the dust can be controlled respectively. Of course, the dust should be conveyed to the mixing device 8 and the slurry production device at different times.

[0031] In some embodiments, the conveying device includes a negative pressure pump, and a negative pressure pump is arranged between the slurry production device and the conveying pipeline 5 and between the mixing device 8 and the conveying pipeline 5. Understandably, the negative pressure pump can guide the dust into the slurry production device or the mixing device 8 under the action of negative pressure.

[0032] In some embodiments, the slurry production device includes a pulper 3 and a slurry collecting box 4, the ash box 2 is connected to the pulper 3 through the conveying device, the pulper 3 is provided with a feeding port to convey the slurry raw material into the pulper 3, and the slurry collecting box 4 is connected to the pulper 3 and the spraying device 9 to convey the slurry to the spraying device 9. In the embodiment of the present application, the dust and the slurry raw material are mixed and processed in the pulper 3 to produce the spraying slurry required by the fiber paper, and the slurry is collected in the slurry collecting box 4 and then conveyed into the spraying device 9.

[0033] Further, the bottom of the pulper 3 is connected to the conveying device, and the feeding port is arranged at the top of the pulper 3. Understandably, the weight of the dust is relatively light, and the weight of the slurry raw material is relatively heavy, so that the dust enters from the bottom of the pulper 3 and moves upward, and the slurry raw material enters from the top of the pulper 3 and moves downward, which can make the two better mixed.

[0034] In some embodiments, the spraying device 9 is connected to the slurry production device to convey the slurry into the spraying device 9 to coat the fiber paper, and the spraying device 9 is connected to the mixing device 8 to convey the mixture of the dust and water into the spraying device 9 to spray the fiber paper coated with the slurry. In the embodiment of the present application, the spraying device 9 needs to be connected to the slurry production device and the mixing device 8 in sequence, so that the slurry produced in the slurry production device is first uniformly coated on the fiber paper to obtain the tobacco paper, and then the spraying liquid is sprayed on the tobacco paper to fill the uneven places on the surface of the tobacco paper, and further make the surface slurry coating more uniform.

[0035] In some embodiments, the bottom of the mixing device 8 is connected to a conveying device. Since the weight of the dust is lighter than the weight of the water, the dust is able to move upward from the bottom of the mixing device 8 and the water is able to move downward from the top of the mixing device 8, which enables better mixing of the two.

[0036] In the embodiments of the present application, the dust collector 1 separates the dust from the conveying airflow and directs the dust into the dust receiving box 2 at the lower end of the dust collector 1, and then transports the dust in the dust receiving box 2 to the pulper 3 under the action of negative pressure through the conveying pipeline 5. The weight monitoring meter 6 monitors the mass of the dust in the dust receiving box 2 in real time, and when the weight of the dust is reduced to a certain value, the valve 7 is signaled to close the conveying passage, thereby ensuring that the amount of dust entering the pulper 3 each time is fixed. Other pulp raw materials are also introduced into the pulper 3 through the feed inlet in a certain proportion, and the pulper 3 reprocesses the dust and the pulp raw materials in a proportional relationship to produce the tobacco pulp required by the process.

[0037] In addition, the conveying pipeline 5 transports the dust in the dust receiving box 2 to the mixing device 8 (where the dust is mixed with water), and the weight monitoring meter 6 and the valve 7 ensure the amount of dust entering the mixing device 8 each time. The dust and water in the mixing device 8 are mixed in a proportional relationship to form the tobacco spraying liquid through processes such as mixing and stirring.

[0038] The tobacco pulp produced in the pulper 3 enters the spraying device 9, and the spraying device 9 sprays the tobacco pulp onto the surface of the fiber paper to complete the first spraying step and form the tobacco paper. After the first spraying step, the surface of the tobacco paper is uneven due to uneven distribution of the pulp on the surface. At this time, the tobacco spraying liquid produced in the mixing device 8 (where the dust is mixed with water) enters the spraying device 9 and is uniformly sprayed on the surface of the tobacco paper through the nozzles therein, which can effectively fill the areas where the pulp on the surface of the tobacco paper is insufficient, and ultimately make the pulp on the surface of the tobacco paper more uniform, thereby ensuring the quality of the tobacco paper.

[0039] The above description of disclosed embodiments enables one skilled in the art to make or use the application. Numerous modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Therefore, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
