Description

Technical Field

[0001] This utility model relates to the field of tobacco storage technology, and in particular to a sealed oxygen-reducing storage device for a three-dimensional shelf stack. Background Technology

[0002] Automated storage racks with sealed tobacco stacks are a storage method that stores tobacco leaves on automated storage racks and seals the stacks. Automated storage racks can make full use of warehouse space, enabling multi-level stacking and increasing storage capacity. Sealed tobacco stacks, on the other hand, form a relatively enclosed space through sealing devices. This not only prevents external moisture and pests from damaging the tobacco leaves, but also allows for control of the gas composition within the sealed space, such as through controlled atmosphere storage, to slow down the oxidation and deterioration of the tobacco leaves, maintain their quality, reduce losses, and improve the efficiency and quality of tobacco storage.

[0003] With the development of the tobacco industry and the increasing demands for tobacco leaf quality, sealed oxygen-reducing storage technology has gradually gained attention. Oxygen-reducing storage can inhibit the respiration of tobacco leaves, reduce oxidation reactions, and prevent discoloration, mold growth, and aroma loss, thereby effectively maintaining the color, aroma, and intrinsic quality of tobacco leaves. However, the existing sealed oxygen-reducing storage devices have simple sealing structures, making it difficult to completely isolate them from the outside air. This leads to continuous oxygen infiltration, making it impossible to maintain a stable low-oxygen environment, which affects the effectiveness of oxygen-reducing storage and causes a decline in tobacco leaf quality. At the same time, gas leakage can occur when connecting nitrogen gas pipelines, thereby compromising the airtightness of the entire storage device and making it difficult to continuously and effectively carry out oxygen-reducing storage.

[0052] Working principle: Storing tobacco;

[0053] First, tobacco is placed inside the storage cabinet 3. A partition 14 on the inner wall of the storage cabinet 3 divides the internal space. Placement plates 15 on both sides of the partition 14 are used to hold the tobacco. Several sets of through holes 16 on the inner walls of the partition 14 and placement plates 15 allow nitrogen gas to circulate evenly inside the storage cabinet 3. When nitrogen gas is introduced into the storage cabinet 3 for deoxygenated storage, the nitrogen gas quickly and evenly diffuses throughout the entire storage cabinet 3 through the through holes 16. It should be noted that the use of the first mounting base 17, the first protective pad 18, the second mounting base 19, and the second protective pad 20 facilitates the installation of the partition 14 and placement plates 15. Simultaneously, the first protective pad 18 and the second protective pad 20 facilitate the installation of the first mounting base 17. The first mounting base 17 and the second mounting base 19 provide cover to prevent the first mounting base 17 and the second mounting base 19 from scratching the packaging bags of the tobacco stack when storing the tobacco stack. The mounting plate 12 at the bottom of the storage cabinet 3 is equipped with rollers 13. The inner wall of the base 10 at the top of the support plate 2 is provided with a sliding groove 11. The rollers 13 are connected to the sliding groove 11 in a rolling manner, which makes the storage cabinet 3 easy to move and position, and facilitates the loading and unloading of tobacco. The inner wall of the storage cabinet 3 is provided with a sealing strip 5, and the inner wall of the cabinet door 4 is provided with a groove 6. When the cabinet door 4 is closed, the groove 6 and the sealing strip 5 fit together to form a preliminary sealing structure, which effectively prevents outside air from entering the storage cabinet 3, maintains a relatively sealed internal environment, and creates basic conditions for oxygen-reduced storage.

[0054] Connection of nitrogen gas transmission pipeline;

[0055] The sleeve 71 in the connecting assembly 7 is connected to the inner wall of the storage cabinet 3. The connecting pipe 72 is inserted into the sleeve 71. The three sets of first sealing rings 73 on the inner wall of the sleeve 71 fit tightly with the outer side of the connecting pipe 72 to ensure a good seal at the connection and prevent gas leakage. When it is necessary to connect a nitrogen gas pipeline, the nitrogen gas pipeline is inserted and connected to the threaded connector 21 on the outer side of the sleeve 71. The groove on the inner wall of the threaded connector 21 can help fix the nitrogen gas pipeline. Then, tighten the threaded connection locking block 22 to allow the external nitrogen gas pipeline to pass through. The gas pipeline and the threaded joint 21 are connected more tightly through a groove, which further enhances the stability and sealing of the connection. When the connecting pipe 72 is not in use, the rubber plug 74 is inserted into the end of the connecting pipe 72 away from the sleeve 71. The second sealing ring 75 on the outside of the rubber plug 74 fits into the inner wall of the connecting pipe 72 to achieve a seal and prevent gas from escaping from the connecting pipe 72. A connecting flange 23 is provided at the connection between the connecting pipe 72 and the rubber plug 74 and it is fixed by two sets of fixing bolts 24 to ensure the reliability of the seal.
