Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production, in particular to a tobacco feeding system Background Art

[0002] The tobacco feeding and flavoring system is an important component of the tobacco silk production line. Through precise control of the flow of liquid feed and flavor and good atomization, the liquid feed and flavor are evenly sprayed on the tobacco material in the proportion required by the process formula.

[0003] Tobacco feeding and flavoring systems usually include components such as material tanks and transmission pipelines. For example, patent CN207383500U discloses a tobacco flavoring and feeding pipeline system, including an air compressor pipeline, a feeding pipeline, a recovery pipeline and an injection pipeline. However, in actual use, there is a certain amount of particle precipitation in the feed liquid. The particulate matter is composed of essential oils, additives, and other chemicals used to adjust the flavor and combustion characteristics of tobacco. After long-term use, the particulate matter is easy to deposit on the pipe wall and the inner wall of the tank body, which not only affects the accuracy of feeding, but also causes equipment failure, increasing downtime and maintenance costs.

[0004] Some tobacco feeding and flavoring systems are also equipped with filters. For example, Patent 202320761115.7 discloses a feeding / flavoring system in which a filter is installed on the conveying pipe at the discharge port of the material tank to filter out particulate impurities in the liquid feed. However, the single-stage filter has low filtration efficiency, requires frequent replacement of the filter medium, and is limited by the flow rate of the feeding pump. As a result, the feeding and flavoring system cannot be cleaned properly. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0028] like Figure 1 — Figure 6As shown, a tobacco feeding system includes: a material tank 1: the material tank 1 includes a first feed port, a second feed port, and a discharge port. The first feed port is provided with a first filter 2; the outlet of the first filter 2 is connected to the pipeline of the first feed port of the material tank 1, and the inlet of the first filter 2 is externally connected to a pressure pump for conveying liquid into the material tank 1 through a pipeline. A ball valve is also installed in the pipeline between the pressure pump and the inlet of the first filter 2. The sealing of the material tank 1 is controlled by controlling the opening and closing of the ball valve. When the ball valve is open, the pressure pump can add liquid to the material tank 1, and the first filter 2 can filter out most of the residual particulate matter in the liquid in advance; when the ball valve is closed, the pressure pump cannot convey liquid into the material tank and the sealing of the first feed port of the material tank 1 is ensured, preventing the volatilization and oxidation of spices or other additives in the liquid, thereby maintaining the stability and concentration of its flavor. At the same time, the seal can also prevent external contaminants from entering the material tank, ensuring the purity and quality of the additives.

[0029] First three-way ball valve 3: its first channel port is connected to the pipeline of the discharge port of the material tank 1, its second channel port is connected to the second filter 4, and is connected to the inlet of the second filter 4. The second filter 4 is used to further filter particles in the feed liquid and is arranged before precision instruments such as the metering pump 7 and the flow meter 10. On the one hand, it can reduce the risk of these precision instruments being blocked, and on the other hand, it can also reduce the impact of particulate matter on its measurement accuracy, allowing it to more accurately control the amount, flow rate, pressure, etc. of the feed liquid. Its third channel port is connected to a flushing component, which is used to flush deposited impurities in the pipeline and provide power for flushing;

[0030] A second three-way ball valve 5: its first channel port is connected to the outlet of the second filter 4, and a drain pipe and a tuning fork liquid level switch 17 are sequentially provided between the first channel port and the second filter 4, wherein the drain pipe is also provided with a ball valve. When the ball valve is opened, the flushing assembly can discharge the flushed impurities out of the entire system through the drain pipe. The second channel port is sequentially connected to the metering pump 7 and is connected to the inlet pipeline of the metering pump 7. The metering pump 7 is used to provide power for the flow of the feed liquid in the system on the one hand, and to control the quantitative flow of the feed liquid on the other hand. The third channel port is connected to the first cleaning pipeline;

[0031] The third three-way ball valve 6: its first channel port is connected to the outlet pipe of the metering pump 7, and a pressure controller 8, a two-position two-way valve 9, a flow meter 10, and a pressure gauge 11 are sequentially arranged between the first channel port and the metering pump 7, its second channel port is connected to the fourth three-way ball valve 12, and the third channel port is connected to the second cleaning and detection component;

[0032] The fourth three-way ball valve 12: its first channel port is connected to the second channel port of the third three-way ball valve 6, its second channel port is connected to the double nozzle 13, and its third channel port is connected to the fifth three-way ball valve 14;

[0033] The fifth three-way ball valve 14 has its first channel port connected to the third channel port of the fourth three-way ball valve 12 , its second channel port connected to the pipeline of the second feed port of the material tank 1 , and its third channel port connected to the third cleaning pipeline.

[0034] like Figure 1 As shown, the feeding and flavoring process of the system is as follows: first, the first channel port and the second channel port of the first three-way ball valve 3 are connected, and the feed liquid in the feed tank 1 flows to the second filter 4, and the particulate matter in the feed liquid is further filtered out by the second filter 4. After the feed liquid flows through the second filter 4, it flows to the tuning fork liquid level switch 17. At this time, the ball valve on the sewage pipe is in a closed state, and the first channel port and the second channel port of the second three-way ball valve 5 are connected to each other. After the feed liquid flows through the second three-way ball valve 5, it passes through the metering pump 7, the pressure controller 8, the two-position two-way valve 9, the flow meter 10, the pressure controller 8, the two-position two-way valve 9, the flow meter 10, the pressure controller 8, the two-position two-way valve 9, the flow meter 11, the pressure controller 8, the two-position two-way valve 9, the flow meter 12, the pressure controller 8, the two-position two-way valve 9, the flow meter 13, the pressure controller 8, the two-position two-way valve 9, the flow meter 14, the pressure controller 8, the two-position two-way valve 9, the flow meter 15, the pressure controller 8, the two-position two-way valve 9, the flow meter 16, the pressure controller 8, the two-position two-way valve 9, the flow meter 17, the pressure controller 8, the two-position two-way valve 9, the flow meter 18, the pressure controller 8, the two-position two-way valve 9, the flow meter 19 ... The liquid flows into the third three-way ball valve 6. At this time, the first channel port and the second channel port of the third three-way ball valve 6 are interconnected. The liquid flows into the fourth three-way ball valve 12. At this time, the first channel port and the second channel port of the fourth three-way ball valve 12 are interconnected. The liquid flows into the double nozzle 13, and the other channel of the double nozzle 13 is externally connected to a pipe for conveying high-pressure steam. The liquid and the high-pressure steam are sprayed out from the double nozzle 13 together. At the same time, the liquid is atomized under the high temperature and pressure of the high-pressure steam and is sprayed onto the tobacco together, completing the primary feeding and flavoring of the tobacco.

[0035] like Figure 2 As shown, after the tobacco is added and flavored once, the liquid may not be used up and may remain. At this time, the first channel port and the third channel port of the fourth three-way ball valve 12 are interconnected, and the excess liquid flows to the fifth three-way ball valve 14 through the fourth three-way ball valve 12. At this time, the first channel port and the second channel port of the fifth three-way ball valve 14 are interconnected, and the liquid flows back into the material tank through the second feed port, realizing the circulation filling of the liquid.

[0036] Specifically, in this embodiment, the flushing assembly includes a water supply pipe and a compressed air supply pipe. The water supply pipe and the compressed air supply pipe are connected in parallel and then connected to the third channel port of the first three-way ball valve 3, and a two-position two-way valve 9 is provided on both the water supply pipe and the compressed air supply pipe.

[0037] like Figure 3As shown, when the system pipeline needs to be drained and cleaned, at this time, the two-position two-way valve 9 on the water pipeline and the compressed air pipeline is opened, the second channel port and the third channel port of the first three-way ball valve 3 are interconnected, the ball valve on the sewage pipe is opened, and the second channel and the third channel of the second three-way ball valve are interconnected (that is, the first channel port is in a closed state). The clean water in the water pipeline and the compressed air in the compressed air pipeline are combined to generate high-pressure water, and the impurities adhered to the pipeline and the second filter 4 are washed off by the high-pressure water, and are directly discharged from the system through the sewage pipe; of course, after the high-pressure water flushing is completed, the two-position two-way valve 9 on the water pipeline or the compressed air pipeline can be opened separately, and the remaining residue in the pipeline can be further cleaned by clean water or compressed air separately.

[0038] Specifically, in this embodiment, the second cleaning and detection component includes a sixth three-way ball valve 15, a detection pipeline and a second cleaning pipeline, wherein the first channel port of the sixth three-way ball valve 15 is connected to the third channel port of the third three-way ball valve 6, the second channel port is connected to the detection pipeline, and the third channel port is connected to the second cleaning pipeline.

[0039] like Figure 4 As shown, the first cleaning pipeline is used for all-round cleaning of the system. At this time, the second channel port and the third channel port of the second three-way ball valve 3 are interconnected, the two-position two-way ball valve 9 is opened, the first channel port and the third channel port of the third three-way ball valve 6 are interconnected (that is, the second channel port is in a closed state), the first channel port and the second channel port of the sixth three-way ball valve 15 are interconnected (that is, the third channel port is in a closed state), the first channel port and the third channel port of the fourth three-way ball valve 12 are interconnected (that is, the second channel port is in a closed state), and the first channel port and the second channel port of the fifth three-way ball valve 14 are interconnected; the first cleaning pipeline is externally connected to a delivery pump for conveying cleaning water, and the delivery pump conveys constant temperature cleaning water of 70°C into the first cleaning pipeline. The cleaning water flows through the metering pump 7, the two-position two-way ball valve 9, the flow meter 10, the fourth three-way ball valve 12, the fifth three-way ball valve 14, the material tank 1, and the second filter 4 in sequence, and then flows out from the sewage outlet to complete the all-round cleaning of the system.

[0040] like Figure 5 As shown, the return pipeline can be cleaned through the second cleaning pipeline. At this time, the second channel port and the third channel port of the third three-way ball valve 6 are connected to each other, the first channel port and the third channel port of the sixth three-way ball valve 15 are connected to each other, the first channel port and the third channel port of the fourth three-way ball valve 12 are connected to each other, and the first channel port and the second channel port of the fifth three-way ball valve 14 are connected to each other. Cleaning water is transported into the system from the second cleaning pipeline for further cleaning of the return pipeline and the material tank 1.

[0041] like Figure 6As shown, the third cleaning pipeline is used for separate cleaning of the material tank 1 and the second filter 4. At this time, the second channel port and the third channel port of the fifth three-way ball valve 14 are connected, the first channel port and the second channel port of the first three-way valve 3 are connected to each other, and the second channel port of the second three-way ball valve 4 is in a closed state. At this time, cleaning water is input from the third cleaning pipeline, and cleans the tank body 1, the second filter 4 and the pipelines therebetween in turn, and is finally discharged from the system from the sewage pipe.

[0042] It should be noted that the cleaning processes of the above-mentioned flushing component, the first cleaning pipe, the second cleaning pipe, and the third cleaning pipe can only be completed one at a time, and multiple processes cannot be carried out at the same time. The next cleaning process can only be carried out after the previous cleaning process is completed; preferably, in actual use, the cleaning process of the flushing component can be set to the end, because the cleaning processes of the first cleaning pipe, the second cleaning pipe, and the third cleaning pipe will all flow through the second filter 4 before passing through the sewage pipe. At this time, the impurities carried during the cleaning process may be blocked on the second filter 4. Therefore, the high-pressure water in the flushing component can more effectively flush away the impurities blocked on the second filter 4, allowing it to flow out of the second filter 4 and out of the sewage pipe, thereby improving the cleaning efficiency.

[0043] Specifically, in this embodiment, the tuning fork level switch 17 can monitor the changes in the liquid level in the pipeline in real time, thereby indirectly reflecting the blockage of the second filter 4. When the blockage of the second filter 4 is severe, the amount of liquid flowing through the second filter 4 will be significantly reduced. At this time, the liquid level in the pipeline will drop, and the tuning fork hydraulic switch will sound an alarm to remind you to clean or replace the second filter 4.

[0044] Specifically, in this embodiment, the pressure controller 8 is a conventional technology, and is used to control the pressure of the feed liquid in the pipeline so that the feed liquid can meet the pressure standard.

[0045] Specifically, in this embodiment, the flow meter 10 is used to detect the specific flow rate of the feed liquid, and the pressure gauge 11 is used to display the real-time pressure of the feed liquid in the pipeline.

[0046] Specifically, in this embodiment, transparent windows 16 are installed on the first cleaning pipeline, the second cleaning pipeline, the third cleaning pipeline, the pipeline between the pressure gauge 11 and the first channel port of the third three-way ball valve 6, and the pipeline between the third channel port of the fourth three-way ball valve 12 and the first channel port of the fifth three-way ball valve 14. The transparent windows 16 can be made of plastic materials such as polycarbonate (PC) or acrylic acid (PMMA), which have good impact resistance and chemical corrosion resistance. At the same time, the transparent windows 16 are used to visually inspect the flow of the liquid inside the pipeline, which is very useful for monitoring the color, state, flow rate of the fluid, and whether there are bubbles or solid particles passing through, helping to promptly detect abnormal conditions.

[0047] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
