[0001] The utility model relates to the field of tobacco processing technology, more particularly, especially, a kind of perfume recovery system of perfuming system. BACKGROUND

[0002] Tobacco perfume usually refers to tobacco flavor, which is an additive specially used for flavoring various tobacco products. In the process of cigarette production, tobacco flavor is usually added at different stages of tobacco processing, such as before cutting, after cutting, before rolling, etc., to achieve the best perfuming effect.

[0003] The raw materials such as perfume used in the process of tobacco production are usually obtained through complex chemical synthesis or extraction process, and have certain economic value. By recycling these perfumes, the effective components can be separated and purified for reuse in tobacco production or other related fields, achieving resource recycling. On the other hand, recycling tobacco perfume can avoid the pollution caused by waste in the production process, such as reducing VOCs emissions and reducing solid waste production.

[0004] However, in the traditional perfume recovery system, the operator needs to manually switch the direction valve frequently, especially during long-term continuous production, which not only increases the workload of the operator, but also is prone to human error, such as misjudging the production stage or the quality of the perfume due to carelessness, causing the direction valve to connect to the wrong pipe, making the perfume flow to the path that does not meet the current actual demand. On the other hand, in the existing production process, it is difficult for the operator to accurately grasp the specific inventory of the perfume in the perfume tank, and only rely on experience or regular manual inspection to roughly judge, which makes the arrangement of perfume supplement and recovery work lack of precision and timeliness. UTILITY MODEL CONTENT

One end of the third pipe 13 is connected to the reversing valve 2, and the other end of the third pipe 13 is connected to the flavoring tank 4.

[0032] It should be noted that a flexible and efficient fragrance liquid recycling network is constructed through the organic combination of three pipelines (first pipeline 11, second pipeline 12, and third pipeline 13) with reversing valve 2, residual liquid tank 3, and fragrance tank 4. Reversing valve 2 precisely guides the fragrance liquid to residual liquid tank 3 or fragrance tank 4 according to subsequent needs, realizing the first step of fragrance liquid classification and treatment, improving the targeting and efficiency of recycling, and avoiding waste of fragrance liquid.

[0033] In this embodiment of the invention, the fragrance recovery system also includes a controller connected to the reversing valve 2. The controller controls the reversing valve 2 to connect to the second pipe 12 or the third pipe 13. The connection between the controller and the reversing valve 2 enables automated control. Operators no longer need to manually switch the reversing valve 2 frequently; they only need to set the parameters in the central control system or a preset program. The controller can then precisely control the reversing valve 2 to connect to the second pipe 12 or the third pipe 13 according to preset logic (such as based on production stage, fragrance quality monitoring data, etc.). This improves operational convenience and reduces human error.

[0034] In this embodiment of the invention, the residual liquid tank 3 adopts a double-layer stainless steel structure. The double-layer stainless steel structure can eliminate the risk of fragrance liquid leakage and prevent secondary pollution to the surrounding environment. The double-layer structure has heat insulation capabilities and can adapt to temperature fluctuations that occur during the heating of cigarettes, ensuring the stability of the fragrance liquid in the residual liquid tank 3.

[0035] In this embodiment of the invention, a self-cleaning coating is provided on the inner wall of the residual liquid tank 3, which effectively solves the problem of dirt accumulation caused by long-term static storage of residual liquid.

[0036] In this embodiment of the invention, a filter 5 is installed on the third pipe 13. The filter 5 has a three-layer filtration structure, wherein the outer layer is configured as a coarse non-woven fabric filter, the middle layer is configured as an activated carbon filter, and the inner layer is configured as an ultrafiltration membrane. This ensures that the flavoring liquid passing through reaches a very high purity standard, guarantees the quality and safety of the recovered flavoring liquid, and fully meets the strict requirements for flavoring heated cigarettes.

[0037] In this embodiment of the invention, the filter 5 is equipped with a differential pressure monitoring device. This device monitors the pressure difference between the inlet and outlet of the filter 5 in real time. When the pressure difference exceeds a set threshold, an alarm is triggered. It should be noted that once the pressure difference exceeds the set threshold, it indicates that the filter medium has been clogged by impurities, resulting in a decrease in filtration efficiency. In this case, an alarm is immediately triggered to remind the operator to replace the filter medium in a timely manner, ensuring that the filter 5 is always in optimal working condition.

[0038] In this embodiment of the invention, the spice container 4 is equipped with a stirring device. When the recycled spice liquid enters the spice container 4, the stirring device is started intermittently to mix the newly recycled spice liquid with the original spice in the container.

[0039] In this embodiment of the invention, the spice tank 4 is equipped with a liquid level monitor, which provides real-time feedback on the amount of spice liquid in the spice tank 4. Operators can use this information to promptly understand the storage status of the spice tank 4, and plan for replenishment or recycling of the spice liquid in advance. This avoids production interruptions due to insufficient spice liquid and also prevents safety hazards caused by excessive storage of spice liquid, ensuring the stable operation of the spice addition system.

[0040] In this embodiment of the invention, a diaphragm pump 6 is connected to the top of the flavoring container 4. The diaphragm pump 6 is used to quantitatively deliver the flavoring liquid inside the flavoring container 4 to the flavoring system. It should be noted that the diaphragm pump 6 has excellent self-priming capability, ensuring stable extraction of flavoring liquid even when the level in the flavoring container 4 is low, thus preventing the flavoring system from shutting down due to insufficient supply. Furthermore, the diaphragm pump 6 can precisely control the delivery volume, ensuring accurate dosage for each flavoring application, resulting in precise and consistent flavoring of heated cigarette products and improving product quality.
