Description

Technical Field

[0001] This utility model relates to the field of wine production technology, and in particular to a wine storage tank for wine production. Background Technology

[0002] Wine storage tanks are specialized containers used in winemaking to store raw wine, base wine, or finished wine. Their core function is to ensure stable aging of the wine during storage, remove impurities, and promote flavor development. They are mostly made of stainless steel (corrosion resistant and easy to clean), earthenware (breathable and helps the wine mature), or glass (suitable for display wines). The capacity and design are adjusted according to the type of wine (white wine, red wine, beer, etc.), making them a key wine storage equipment in the winemaking industry chain.

[0003] While earthenware jars possess breathable properties that aid in the aging of wine, they suffer from a sealing weakness—they are prone to leakage and are significantly affected by external humidity, making it difficult to stabilize the microenvironment for wine storage. Stainless steel jars offer excellent sealing performance and can effectively isolate external interference, but their poor breathability hinders the "breathing" and aging of baijiu (Chinese liquor). This is similar to the frequent barrel transfers and oxygen replenishment required in red wine production, which is not only cumbersome but also increases the risk of wine loss and contamination. Utility Model Content

[0004] This invention provides a wine storage tank for wine production to solve the above-mentioned problems.

[0005] This utility model provides a wine storage tank for wine production, including: a stainless steel seal, comprising a fixed layer plate fixedly connected to the inner wall of the wine storage tank, a limiting rotating shaft fixedly sleeved inside the fixed layer plate, a sealing cover plate movably sleeved on the outer wall of the limiting rotating shaft, an internal gear ring fixedly connected to the top of the sealing cover plate, and a gear meshing on the inner wall of the internal gear ring, for opening and closing the stainless steel inner cover inside the wine storage tank.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] like Figures 1 to 4As shown, this application provides a wine storage tank for wine production, with a stainless steel seal, including a fixed layer plate 8 fixedly connected to the inner wall of the storage tank 1, a limiting shaft 5 fixedly sleeved inside the fixed layer plate 8, a sealing cover plate 9 movably sleeved on the outer wall of the limiting shaft 5, an internal gear ring 11 fixedly connected to the top of the sealing cover plate 9, and a gear 13 meshing on the inner wall of the internal gear ring 11, used for opening and closing the stainless steel inner cover inside the storage tank 1. A transmission shaft 14 is fixedly sleeved on the inner wall of the gear 13, and the outer wall of the transmission shaft 14 is movably sleeved with the storage tank 1.

[0026] With the above technical solution, when an absolutely sealed storage environment is required for the wine storage tank 1, the transmission shaft 14 can be driven by an external power source to rotate precisely inside the wine storage tank 1, thereby driving the gear 13 at its bottom to rotate synchronously. Under the precise meshing action of the gear 13 and the internal gear ring 11, the internal gear ring 11 will drive the sealing cover 9, which is fixedly connected to its bottom end, to rotate stably around the limiting shaft 5. After the sealing cover 9 completes a 180-degree rotation, it and the fixed layer 8 will form a complete closed structure, achieving a tight seal from the inside of the wine storage tank 1. The overlapping design of the edges of the two can effectively eliminate gaps, providing a sealed storage environment for the wine inside the tank to isolate it from external pollution, ensuring that the wine is not affected by oxidation and impurities during long-term storage.

[0027] In an optional embodiment, the clay seal includes a clay cover plate 3, three sets of extension blocks 15 fixedly connected to the outer wall of the clay cover plate 3, a connecting shaft 4 movably sleeved inside one set of extension blocks 15, a support rod 16 fixedly connected to the bottom end of another set of extension blocks 15, and a limiting pin 7 movably inserted inside the last set of extension blocks 15, for secondary sealing of the wine storage tank 1.

[0028] During the production process, when the wine needs to be properly aerated to promote aging, the inner stainless steel layer can be opened to leave the lid open. At this time, the clay lid 3 at the top of the storage tank 1 will allow for natural gas exchange between the inside and outside of the tank, thanks to the unique microporous permeability of the clay material. Fresh air from the outside can slowly seep in through the clay micropores, replenishing the oxygen needed in the tank. At the same time, volatile substances generated inside the tank can also be appropriately discharged. This design does not require opening the lid completely, which satisfies the wine's breathing needs while avoiding the loss of wine due to evaporation caused by fully opening the lid. It also significantly reduces the risk of external dust, microorganisms, and other contaminants entering, thus balancing aeration and storage safety.

[0029] An extension cap 2 is fixedly connected to the top of the wine storage tank 1. A clay lid 3 is attached to the top of the extension cap 2. A handle 6 is fixedly connected to the top of the clay lid 3.

[0030] When cleaning and maintenance of the interior of the storage tank 1 is required, first open the clay lid 3. Simply pull out the retaining pin 7 that is movably inserted inside one set of extension blocks 15. After releasing the fixation, the operator can pull the handle 6 to allow the clay lid 3 to rotate flexibly around the connecting shaft 4. During the rotation of the lid, the arc groove on its edge reduces the frictional resistance with the extension cylinder 2, ensuring smooth opening and closing. When the clay lid 3 is completely removed from the top of the extension cylinder 2, the tank opening is fully open, facilitating the entry of cleaning personnel and tools into the tank. It is worth noting that after the clay lid 3 is opened, the support rod 16 automatically forms a stable support, forming a three-point load-bearing structure together with the connecting shaft 4 and the edge of the extension cylinder 2. This effectively distributes the weight of the lid, significantly reducing the force required for manual opening and closing, improving operational convenience, and preventing damage to the connecting parts due to the excessive weight of the lid.

[0031] In an optional embodiment, the fixed shelf 8 and the sealing cover 9 are the same size, and the bottom end of the sealing cover 9 is attached to the fixed shelf 8. The size of both the fixed shelf 8 and the sealing cover 9 is three-fifths of the inner diameter of the wine storage tank 1. With the dimensions of both the fixed shelf 8 and the sealing cover 9 set to three-fifths of the inner diameter of the wine storage tank 1, in the closed state, the overlapping area of ​​the two enhances the sealing redundancy of the connection; while in the ventilated mode, the non-overlapping space provides sufficient channels for gas flow, ensuring efficient oxygen supply.

[0032] In an optional embodiment, a supporting arc-shaped plate 12 is fixedly connected to the side of the fixed layer plate 8, and the outer wall of the supporting arc-shaped plate 12 is fixedly connected to the wine storage tank 1. The supporting arc-shaped plate 12 provides a load-bearing fulcrum that conforms to the curvature of the sealed cover plate 9 after it is closed, which can evenly distribute the weight of the cover plate to the tank wall, avoid structural deformation caused by stress concentration after long-term use, and further improve the stability and service life of the equipment.

[0033] In an optional embodiment, a sealing strip 10 is provided at the top of the supporting arc plate 12. The outer wall of the sealing strip 10 is fixedly connected to the wine storage tank 1, and the bottom end of the sealing strip 10 is fixedly connected to the top of the sealing cover plate 9. The sealing strip 10 pre-set at the top of the sealing cover plate 9 fills the tiny gaps at the edges, which can block the exchange of gases between the inside and outside to the maximum extent, ensuring that the wine is protected from oxidation and impurities during long-term storage.

[0034] In one optional embodiment, the top of the wine storage tank 1 is provided with an arc groove, and a support rod 16 is movably fitted onto the inner wall of the arc groove. The arc groove facilitates the opening and closing of the clay lid 3, ensuring smooth opening and closing.
