Description

Technical Field

[0001] This utility model belongs to the field of grape winemaking technology, specifically relating to a variable volume wine storage tank. Background Technology

[0002] Fruit wine and grape wine are fermented alcoholic beverages produced through natural fermentation. Grape wine is a type of fruit wine, made from 100% grapes or grape juice. The production of grape wine requires selecting fully ripe grapes, which undergo sorting, washing, drying, destemming, pressing, adding sugar, bottling (with the addition of sulfites, pectinase, etc.), primary fermentation, secondary fermentation, clarification, distillation, and blending.

[0003] Wine requires full storage during its production and aging process. While wine storage tanks are typically fixed-volume, the unpredictable yield during fermentation often leads to tanks not being fully filled, resulting in wasted storage space. Furthermore, when tanks are not full, air is trapped inside, causing excessive contact between the wine and air. This oxidation affects the wine's flavor and quality, and can even lead to spoilage. Unstable whirling... To prevent oxidation of wine due to the presence of air, small tanks of varying volumes can be used, with nitrogen gas filling the top to protect the wine from oxidation. However, even with small tanks, the wine is often not fully filled. Using tanks of different sizes also reduces the utilization rate of the wine storage capacity for producers and increases production costs. Nitrogen filling is expensive, and nitrogen cannot completely remove the existing air from the tank, leaving residual oxygen inside.

[0004] Therefore, wine storage tanks sometimes use liftable covers. The lifting of the cover can be controlled by a winch. During use, the hoisting rope of the winch needs to pull the cover for a long time to maintain its position, which puts a large load on the winch, consumes a lot of energy, and is prone to unstable winch operation, resulting in unstable cover position and affecting the long-term use of the wine storage tank. Utility Model Content

[0005] The purpose of this utility model is to provide a variable volume wine storage tank, which aims to solve the problem that the wine storage tank uses a winch to drive the lifting and lowering of the cover plate, and the winch is unstable and consumes a lot of energy.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a variable volume wine storage tank is provided, comprising: a tank body having an open storage cavity for storing wine, the inner side wall of the tank body being provided with multiple sets of clamping structures, the multiple sets of clamping structures being spaced apart along the height direction of the tank body, the inner side wall of the tank body being provided with vertically arranged sliding rails, and the bottom end of the tank body being provided with a lower valve; A lifting cover includes a main board, a left flap, and a right flap; the main board is horizontally positioned and slidably connected to the sliding rail; the left flap and the right flap are respectively hinged to the left and right sides of the main board, and the left flap and the right flap have the freedom to tilt and flip upwards; when the left flap and the right flap are flipped to a horizontal position and rest on one of the set of clamping structures, the main board, the left flap, and the right flap combine to form a sealing structure adapted to the open storage cavity; and A flip-plate assembly is disposed on the main board and connected to the left flip-plate and the right flip-plate, and is used to drive the left flip-plate and the right flip-plate to flip. A lifting assembly is used to drive the lifting cover plate to rise and fall.

[0007] In one possible implementation, the card-mounting structure includes: A transverse connecting plate, one end of which is disposed on the side wall of the tank; and A vertical connecting plate is disposed on the upper end face of the other end of the horizontal connecting plate; The lower end of the left flap / right flap is provided with a locking block, which is adapted to be embedded in the locking groove formed by the vertical connecting plate and the side wall of the tank.

[0008] In one possible implementation, the lifting component includes: A winch is installed on the ground outside the tank; and A steering pulley is located at the upper end of the side wall of the tank. The hoisting rope of the winch is routed upwards around the steering pulley and is mounted on the main board.

[0009] In one possible implementation, the lifting ropes of the two sets of lifting components are symmetrically arranged at the front and rear ends of the main board.

[0010] In one possible implementation, the flip-up assembly includes: A drive connection block is mounted above the motherboard via a drive component, which is used to drive the drive connection block to move up and down. The left drive lever is hinged at one end to the left side of the drive connecting block and at the other end to the upper surface of the left flap; and The right drive rod is hinged at one end to the right side of the drive connecting block and at the other end to the upper surface of the right flap. The driving component drives the driving connecting block to rise, which in turn drives the left driving rod and the right driving rod to rise, thereby enabling the left flip plate and the right flip plate to flip upward.

[0011] In one possible implementation, the driving component is a screw, the lower end of which is rotatably mounted on the main board, and the driving connecting block is sleeved on the outside of the screw, with the two threadedly matched.

[0012] In one possible implementation, a limit block is provided on the screw, and the limit block is located below the drive connecting block. When the left flap and the right flap are horizontal, the drive connecting block abuts against the upper end face of the limit block.

[0013] In one possible implementation, an airbag is provided on the lower end face of the lifting cover, and the inflation port of the airbag extends upward through the lifting cover.

The sliding rail can also restrict the circumferential rotation of the lifting cover. The lower valve is located at the lower end of the side wall of the tank and connects to the inside of the tank. It can be used to discharge the liquid inside the tank. The lower valve can also be connected to the feed pipe, and raw materials such as grapes can be discharged into the tank through the lower valve. Multiple sets of clamping structures are set on the inner side wall of the tank and distributed along the height direction of the tank. The lower end face of the lifting cover is adapted to abut against the clamping structure. The clamping structure is used to limit the position of the lifting cover. During the use of the device, the clamping structure increases the stability of the lifting cover's position limit. The lifting assembly is used to drive the lifting cover to rise and fall, facilitating the adjustment of the position of the lifting cover; The lifting cover includes a main board, a left flap, and a right flap. The main board is horizontally positioned and slidably mounted on a sliding rail. The left flap is hinged to the left side of the main board, and the right flap is hinged to the right side of the main board. The flap assembly is mounted on the main board and can drive the left and right flaps to flip upwards. When the left and right flaps disengage from the locking structure, the lifting cover avoids the locking structure. The lifting cover has the freedom to slide up and down. Adjusting the height of the lifting cover can adjust the volume of wine stored in the tank. When the lifting cover is adjusted to the predetermined position, the left and right flaps are adjusted to be horizontal, and the edges of the left and right flaps can abut against the upper part of the locking structure. The locking structure supports the lifting cover and restricts its displacement. At this time, the lifting assembly does not need to apply force to the lifting cover and can stop working, saving energy. The lifting cover can achieve stable positioning and seal the wine in the tank to prevent oxidation. Attached Figure Description
