Description

Technical Field

[0001] This utility model relates to the field of tobacco aging, and in particular to a pipeline system for tobacco warehouses. Background Technology

[0002] After harvesting and curing, tobacco often undergoes aging and storage to remove its raw, unpleasant odors, reduce its harshness, improve its aroma, and harmonize its chemical components. Natural aging and storage of tobacco typically takes about three years. Furthermore, due to varying environmental conditions, the aging process can be inconsistent, leading to significant fluctuations in product quality. Additionally, long-term storage can result in problems such as moisture absorption, mold growth, or insect damage. Moreover, the substantial capital tied up in long-term tobacco storage places a significant financial burden on tobacco factories.

[0003] Consequently, artificial aging technology has been gradually applied to the storage and aging of tobacco. By utilizing technological means to scientifically process and manage tobacco, it aims to promote physiological and biochemical changes in tobacco, thereby altering and improving its quality. In the storage and aging management of tobacco, precise control of temperature and humidity is necessary to prevent moisture absorption, mold growth, and damage from pests. Modified atmosphere packaging (MAP), as a green and environmentally friendly technology, is increasingly being applied to the artificial aging of tobacco. It can achieve precise temperature and humidity control and prevent pests during storage. Therefore, a completely new pipeline system needs to be designed to meet the management and control requirements of tobacco storage and aging. Utility Model Content

The tobacco warehouse includes a main body with multiple tobacco stacks arranged within it. Each tobacco stack is surrounded by a flexible, airtight tent sealed with a flexible membrane. The pipeline system includes: a gas supply pipeline extending from the outside of the main body and laid along its inner wall, connected to the air inlet of the flexible, airtight tent, for supplying gas to the tobacco stacks; an exhaust pipeline connected to the exhaust port of the flexible, airtight tent, laid along its inner wall and exiting the main body, for discharging gas from the tobacco stacks; multiple detection pipelines laid along the exhaust pipeline and connected to the exhaust ports of the flexible, airtight tents of the multiple tobacco stacks, for detecting gas parameters in the tobacco stacks; and a humidification pipeline located outside the main body and connected to the gas supply pipeline, for regulating the humidity of the gas in the tobacco stacks.

[0005] The pipeline system described above further includes: connectors for laying the gas supply pipeline and / or the exhaust pipeline on the inner wall of the warehouse body.

[0006] In the pipeline system described above, the connector is one or more of the following: bracket, support, screw rod, and upright frame, used to fix or hoist the gas supply pipeline and / or the exhaust pipeline to the inner wall of the warehouse main body.

[0007] As described above, the gas supply line and / or the exhaust line includes a main line and one or more branch lines, wherein the branch lines connect the main line to the inlet gas of the flexible airtight tent or the exhaust port of the flexible airtight tent.

[0009] In the pipeline system described above, the air inlets and outlets of two adjacent flexible airtight tents are interconnected.

[0010] In the pipeline system described above, the air inlet and exhaust outlet of the flexible airtight tent are located on opposite sides of the flexible airtight tent.

[0011] In the pipeline system described above, the diameter of the air supply pipeline is one-quarter, one-third, one-half, two-thirds, or three-quarters of the diameter of the exhaust pipeline, to ensure that the air supply pipeline and the airtight tent can form a positive pressure.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In the following detailed description, reference can be made to the accompanying drawings, which form part of this application and illustrate specific embodiments of the present application. In the drawings, similar reference numerals describe substantially similar components in different figures. Specific embodiments of the present application are described in sufficient detail below to enable those skilled in the art to implement the technical solutions of the present application. It should be understood that other embodiments may also be utilized, or structural, logical, or electrical changes may be made to the embodiments of the present application.

[0022] This application proposes a pipe network system that can be applied to tobacco warehouses to precisely control humidity and pest control during the tobacco storage and aging process, enabling scientific management of the tobacco storage and aging process. In some embodiments, this application also proposes various forms of pipe network systems that can provide different forms of control over the tobacco.

[0023] The technical solution of this application will be further illustrated below through specific embodiments. Those skilled in the art should understand that the following description is merely for the convenience of understanding the technical solution of the application and should not be used to limit the scope of protection of this application.

[0024] Figure 1 This is a schematic diagram of a pipeline system according to an embodiment of this application. Figure 2This is a partially enlarged view of a pipeline system according to an embodiment of this application. As shown, the tobacco warehouse includes a warehouse body 10, in which multiple tobacco stacks 11 are arranged. Each tobacco stack 11 is surrounded by a flexible airtight tent (not shown) sealed with a flexible membrane, which can seal the tobacco stacks. In some embodiments, this application uses 17 tobacco stacks arranged in two rows in the warehouse body as an example to illustrate the technical solution of this application. As those skilled in the art will understand, the tobacco stacks in the warehouse body can also have other arrangements and numbers.

[0025] As shown in the figure, the pipeline system 100 is installed in the tobacco warehouse, and may include: a gas supply pipeline 110, an exhaust pipeline 120, multiple detection pipelines 130, and a humidification pipeline 140. The gas supply pipeline 110 enters the main body of the warehouse from the outside and runs along the inner wall of the main body 10, connecting to the air inlet of the flexible airtight tent of the tobacco stack 11, providing gas (such as low-oxygen or normal-oxygen gas) to the tobacco stack. The exhaust pipeline 120 connects to the exhaust port of the flexible airtight tent and runs along the inner wall of the main body of the warehouse 10, exiting from the main body of the warehouse 10 to the outside, venting gas from the tobacco stack and thus exchanging gas within it. The multiple detection pipelines 130 run along the exhaust pipeline 120 and connect to the exhaust ports of the flexible airtight tents of the multiple tobacco stacks, respectively, for detecting gas parameters (such as oxygen content and humidity) within the tobacco stack. The humidification pipe 140 is located outside the main body 10 of the warehouse and is connected to the gas supply pipe 110. It can be used to regulate the humidity of the gas in the tobacco stack.

[0026] In some embodiments, the piping system 100 may further include connectors (not shown) for laying gas supply and / or exhaust pipes on the inner wall of the warehouse body 10. In some embodiments, the connectors may be brackets, supports, etc., to securely lay the gas supply and / or exhaust pipes on the inner wall of the warehouse body 10. In some embodiments, the connectors may also be threaded rods, uprights, etc., to hoist and lay the gas supply and / or exhaust pipes on the inner wall of the warehouse body 10.

[0027] In some embodiments, the piping system 100 may further include a control valve 150, which may be installed on the gas supply line, exhaust line, detection line, and / or humidification line, and may be used to control the on / off state of the lines, thereby regulating the gas environment in the tobacco stack. In some embodiments, the control valve 150 may be an electric valve, a pneumatic valve, a manual valve, etc., and may enable individual regulation of each tobacco stack in the tobacco warehouse. In some embodiments, the control valve 150 may also control the air intake or exhaust flow of each tobacco stack by the degree of valve opening and closing, thereby ensuring that the regulation completion time of each tobacco stack is consistent.

[0028] In some embodiments, the gas supply pipe and / or exhaust pipe can be made of U-PVC, which is advantageous due to its light weight, acid and alkali resistance, flame resistance, pressure resistance, and smooth inner wall with low resistance. In some embodiments, the diameter of the gas supply pipe can be one-quarter, one-third, one-half, two-thirds, or three-quarters of the diameter of the exhaust pipe. By using a smaller diameter gas supply pipe and a larger diameter exhaust pipe in combination, the intake pressure of the tobacco stack can be increased, promoting the turbulence of the gas within the tobacco stack. This ensures that the gas supply pipe and the flexible airtight tent form a positive pressure, which is beneficial for improving oxygen reduction efficiency. Increasing the diameter of the exhaust pipe can promote the smoothness of exhaust. According to one embodiment of this application, the diameter of the intake pipe can be 50 mm, and the diameter of the exhaust pipe can be 100 mm.

[0029] In some embodiments, the gas supply line 110 may include a main line 111 and branch lines 112. The main line 111 is connected to equipment outside the main storage facility (such as a nitrogen generator), and the branch lines 112 are connected from the main line to the air inlet of the flexible airtight tent. (Reference) Figure 2 In some embodiments, the air supply line 110 may also include a secondary line 113, which is connected to the branch line 112 and the air inlet of the flexible airtight tent. Adjacent tents may share a branch line 112, which is connected to the air inlet of the flexible airtight tent by the secondary line 113. This facilitates the aesthetics of the pipeline layout, reduces the use of branch lines, saves the cost of pipeline layout, and saves space in the main body of the warehouse.

[0030] In some embodiments, the exhaust pipe 120 may include a main pipe 121 and branch pipes 122. The main pipe 121 is connected to the outside of the warehouse main body, and the branch pipes 122 are connected from the main pipe to the exhaust port of the flexible airtight tent. In some embodiments, the exhaust pipe 120 may further include a secondary pipe 123, which connects to the branch pipe 122 and the exhaust port of the flexible airtight tent. Adjacent tents may share a single branch pipe 122, with the secondary pipe 123 connecting to the exhaust port of the flexible airtight tent. This facilitates an aesthetically pleasing pipe network layout, reduces the use of branch pipes, saves on pipe network layout costs, and conserves space within the warehouse main body. In some embodiments, the air inlet and exhaust outlet of the flexible airtight tent may be located on opposite sides, allowing the air inlet and exhaust pipes to be positioned on opposite sides of the flexible airtight tent, facilitating gas exchange within the tobacco stack.

[0031] In some embodiments, the detection pipeline 130 can be a PU tube with an inner diameter of 4mm and an outer diameter of 6mm. Connected to the exhaust port of the flexible airtight tent, the detection pipeline can extract gas from the tent for testing. This allows the detection pipeline to possess advantages such as high airtightness, light weight, acid and alkali resistance, flame resistance, pressure resistance, and a smooth inner wall with low resistance. In some embodiments, multiple detection pipelines 130 can be connected to the flexible airtight tents of multiple tobacco stacks, and their data can be aggregated into a single detection terminal (such as a control box). This enables unified data detection, facilitates the centralization of tobacco warehouse detection data, and makes data easy to access.

[0032] In some embodiments, multiple detection pipes 130 can be concealed on the back side of the exhaust pipe, which helps to improve the aesthetics and neatness of the pipe network layout. In some embodiments, the detection pipes are laid on the back side of the exhaust pipe using cable ties, which allows the detection pipes to be laid on the exhaust pipe. In some embodiments, the spacing of the cable ties can be 1m, which can effectively prevent the pipes from becoming loose and messy, and contributes to the aesthetics and neatness of the pipe network. In some embodiments, the pipe openings of the detection pipes need to be sealed before laying to prevent dust or particles from entering during the laying process, thereby affecting the detection end. In some embodiments, the detection pipe 130 may also include a filter (not shown in the figure), which can be used to filter dust or particles in the detection gas to prevent dust or particles from being inhaled during the gas extraction detection process.

[0033] In some embodiments, the humidification pipeline 140 can be connected in parallel to the front end of the main gas supply pipeline, and can regulate the humidity of the gas in the gas supply pipeline, thereby controlling the humidity of the gas in the tobacco stack. In some embodiments, the humidity of the humidification pipeline can be adjusted in different modes by means of a control valve. For example, when the equipment supplies gas to the tobacco stack, the humidity of the gas in the gas supply pipeline can be directly regulated; or, when the equipment does not supply gas to the tobacco stack, the humidification pipeline can also directly supply humidity-regulating gas to the tobacco stack from the gas supply pipeline, thereby regulating the gas environment of the tobacco stack.

[0034] As described above, when the pipeline system of this application supplies gas to tobacco stacks, the gas supply pipeline can simultaneously supply gas to multiple tobacco stacks. This application also proposes other forms of pipeline systems that can realize different gas supply methods, which will be described in detail below. For ease of understanding, in the following embodiments, only the gas supply pipeline and exhaust pipeline structures are used to describe different gas supply methods; the detection pipeline and humidification pipeline are not described. Figure 1 The implementation examples are similar, so they will not be repeated here.

[0035] Figure 3 This is a schematic diagram of a pipeline system according to another embodiment of this application.

[0036] As shown in the figure, the pipeline system 300 includes a gas supply pipe 310 and an exhaust pipe 320. The gas supply pipe 310 enters the main body of the warehouse 10 from the outside and runs along the inner wall of the main body 10, connecting to the air inlet of the flexible airtight tent of the tobacco stack 11, thus supplying gas to the tobacco stack. The exhaust pipe 320 connects to the exhaust outlet of the flexible airtight tent and runs along the inner wall of the main body of the warehouse 10, exiting from the main body of the warehouse 10 to the outside, and is used to exhaust gas from the tobacco stack, thereby facilitating gas exchange within the tobacco stack.

[0037] In some embodiments, the air supply line 310 may include a main line 311 and branch lines 312. The main line 311 is connected to equipment outside the main warehouse structure, and the branch line 312 is connected from the main line to the air inlet of a flexible airtight tent. Connecting lines 301 are included between other arranged flexible airtight tents, allowing the tents to be connected end-to-end. In some embodiments, the exhaust line 320 may include a main line 321 and branch lines 322. The main line 321 is connected to the outside of the main warehouse structure, and the branch line 322 is connected from the main line to the exhaust port of the last arranged flexible airtight tent.

[0038] Thus, multiple flexible airtight tents of tobacco stacks are connected in series. When the pipeline system supplies gas to the tobacco stacks, the gas supply pipe 310 supplies gas to one tobacco stack, which in turn supplies gas to the other flexible tents. In some embodiments, the connecting pipes between the multiple flexible tents can be connected with flexible hoses to facilitate changing the series order of the flexible airtight tents at any time.

[0039] Figure 4 This is a schematic diagram of a pipeline system according to another embodiment of this application.

[0040] As shown in the figure, the pipeline system 400 includes a gas supply pipe 410 and an exhaust pipe 420. The gas supply pipe 410 enters the main body of the warehouse 10 from the outside and runs along the inner wall of the main body 10, connecting to the air inlet of the flexible airtight tent of the tobacco stack 11, thus supplying gas to the tobacco stack. The exhaust pipe 420 connects to the exhaust outlet of the flexible airtight tent and runs along the inner wall of the main body of the warehouse 10, exiting from the main body of the warehouse 10 to the outside, and is used to exhaust gas from the tobacco stack, thereby facilitating gas exchange within the tobacco stack.

[0041] In some embodiments, the air supply line 410 may include a main line 411 and a branch line 412. The main line 411 is connected to equipment outside the main warehouse structure, and the branch line 412 is connected from the main line to the air inlet of the flexible airtight tent. In some embodiments, the exhaust line 420 may include a main line 421 and a branch line 422. The main line 421 is connected to the outside of the main warehouse structure, and the branch line 422 is connected from the main line to the exhaust outlet of the flexible airtight tent.

[0042] In some embodiments, a connecting pipe 401 may be included between multiple flexible airtight tents, which can connect adjacent tents end to end. When the pipe network system 400 supplies gas to the tobacco stacks, the gas supply pipe 410 supplies gas to the first tobacco stack, and the gas discharged from the first tobacco stack enters the second tobacco stack, and so on. When the first tobacco stack meets the gas supply standard, the gas supply pipe 410 can directly supply gas to the second tobacco stack, and the gas discharged from the second tobacco stack enters the third tobacco stack, and so on. Thus, by supplying gas to the tobacco stacks, gas can be pre-supplied to the subsequently arranged tobacco stacks, thereby speeding up the gas supply rate and shortening the gas supply time.

[0043] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention.
