Description

Technical Field

[0001] This utility model belongs to the technical field of fermentation tanks for rice wine, and in particular relates to a fermentation tank for rice wine. Background Technology

[0002] Fermentation tanks are bioreactors specifically designed for brewing alcoholic beverages. Their core function is to provide a controlled fermentation environment for microorganisms such as yeast, converting sugars into alcohol and flavor compounds. Fermentation tanks are typically made of materials such as stainless steel, oak, concrete, or terracotta. Among these, stainless steel fermentation tanks are widely used in the production of alcoholic beverages such as wine and beer due to their durability, corrosion resistance, and ease of cleaning.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing rice wine fermentation tanks: 1. The contact area between the sealing cap and the sealing gasket is small, resulting in a poor sealing effect of the sealing cap. It is inconvenient to set conical contact measures on the sealing cap and the sealing gasket to increase the contact area and improve the sealing effect. 2. The lower end of the climbing ladder is suspended in the air, which means that the stress point is at the weld between the fermentation tank and the climbing ladder. It is prone to breakage under stress, and it is inconvenient to install adjustment measures on the climbing ladder to make the lower end of the climbing ladder touch the ground. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a fermentation tank for rice wine, which solves the following issues: the existing sealing cap and sealing gasket have a small contact area, resulting in poor sealing performance; it is inconvenient to add conical contact measures to the sealing cap and sealing gasket to increase the contact area and improve the sealing effect; the lower end of the climbing ladder is suspended, causing the stress point to be at the weld between the fermentation tank and the climbing ladder, which is prone to breakage under stress; and it is inconvenient to add adjustment measures to the climbing ladder to make the lower end of the climbing ladder touch the ground.

[0005] The purpose and effects of this new type of fermentation tank for rice wine are achieved through the following specific technical means: A fermentation tank for rice wine includes a fermentation tank body; the fermentation tank body is provided with a fermentation tank shell in the vertical direction, and an internally threaded cylinder is provided at the front top of the fermentation tank shell. A rubber sealing gasket is placed inside the internally threaded cylinder of the fermentation tank shell. A conical annular groove is provided on the inner circumference of the top of the rubber sealing gasket. A rotating sealing cover is installed inside the internally threaded cylinder of the fermentation tank shell by threads. The outer circumference of the rotating sealing cover is threaded. A truncated frustum is provided on the bottom end face of the rotating sealing cover. A regular hexagonal prism is provided in the middle of the top end face of the rotating sealing cover.

[0006] Furthermore, a ground-contacting rubber column is inserted inside the bottom of the force-adjusting cylinder, an insertion column is provided on the upper part of the ground-contacting rubber column, and a ground-contacting disc is provided at the bottom of the insertion column of the ground-contacting rubber column.

[0007] Furthermore, the bottom outer circumference of the uprights on both sides of the climbing ladder is equipped with a force adjustment cylinder by threads. The inner circumference of the force adjustment cylinder is threaded, and the bottom outer circumference of the force adjustment cylinder is provided with a regular hexagonal structure.

[0008] Furthermore, an assembly anti-detachment column is installed inside the threaded blind hole of the operating climbing ladder. A limit circular plate is provided on the upper part of the assembly anti-detachment column, a threaded column is provided on the bottom end face of the limit circular plate of the assembly anti-detachment column, and a regular hexagonal groove is opened on the top end face of the limit circular plate of the assembly anti-detachment column.

[0009] Furthermore, a protective opening ring is fitted between the tops of the uprights on both sides of the operating climbing ladder, and sleeves in the up-down direction are provided at both ends of the protective opening ring.

[0010] Furthermore, an operating ladder in the vertical direction is welded to the front of the outer circumference of the fermentation tank shell. Threaded blind holes are opened on the top end face of the uprights on both sides of the operating ladder, and threads are opened on the outer circumference of the bottom of the uprights on both sides of the operating ladder. The outer circumference surface of the crossbar of the operating ladder is provided with a frosted surface.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The convenient rotating sealing cap is threaded onto the fermenter shell to press the rubber sealing gasket, allowing the inverted frustum of the rotating sealing cap to press into the conical annular groove of the rubber sealing gasket. This solves the problem of insufficient contact area between the sealing cap and the sealing gasket, resulting in poor sealing performance, and the inconvenience of setting conical contact measures on the sealing cap and the sealing gasket to increase the contact area and improve the sealing effect.

[0012] The convenient force-adjusting cylinder is installed on the operating ladder via threads, so that the force of the operating ladder is applied to the ground through the force-adjusting cylinder and the ground-contacting rubber column. This solves the problem that the lower end of the ladder is in a suspended state, which causes the stress point to be at the weld between the fermentation tank and the ladder, making it prone to breakage under stress and inconvenient to install adjustment measures on the ladder to make the lower end of the ladder touch the ground.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0021] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a fermentation tank for brewing wine, including a fermentation tank body 1. The fermentation tank body 1 is provided with a fermentation tank shell 2 in a vertical direction, which facilitates brewing fermentation and supports various components. An internally threaded cylinder is provided at the top front of the fermentation tank shell 2, which facilitates the installation and removal of the rotating sealing cap 4 via threads, and facilitates the insertion and positioning of the rubber sealing gasket 3. The rubber sealing gasket 3 is placed inside the internally threaded cylinder of the fermentation tank shell 2, which facilitates the sealing of the rubber sealing gasket 3 by the compression of the rotating sealing cap 4. The top inner circumference of the rubber sealing gasket 3 is provided with a conical annular groove, which facilitates the mutual fitting with the inverted frustum of the rotating sealing cap 4, thereby increasing the contact area and improving the sealing effect. The rotating sealing cap 4 is installed inside the internally threaded cylinder of the fermentation tank shell 2 via threads, which facilitates the application of compression force to the rubber sealing gasket 3 for sealing. The outer circumference is threaded to facilitate the installation and removal of the rotating sealing cover 4. The bottom end face of the rotating sealing cover 4 is provided with an inverted frustum to facilitate its mating with the conical annular groove of the rubber sealing gasket 3. The top end face of the rotating sealing cover 4 is provided with a regular hexagonal prism to facilitate the rotation and removal of the rotating sealing cover 4 using tools. The front of the outer circumference of the fermentation tank shell 2 is welded with an operating ladder 5 in the vertical direction, which is convenient for staff to climb up and down. The top end face of the uprights on both sides of the operating ladder 5 is provided with threaded blind holes to facilitate the installation of the anti-detachment column 7 by threads. The bottom outer circumference of the uprights on both sides of the operating ladder 5 is also threaded to facilitate the installation of the force adjustment cylinder 8 by threads. The outer circumference surface of the crossbar of the operating ladder 5 is provided with a frosted surface to facilitate the anti-slip of the staff's feet.

[0022] The operating ladder 5 has a protective opening ring 6 fitted between the tops of the uprights on both sides. This ring protects the worker's back when climbing to the top, preventing them from falling backward and freeing their hands to operate the top components of the fermenter body 1. Both ends of the protective opening ring 6 have sleeves running vertically, allowing it to fit snugly between the tops of the uprights on both sides of the operating ladder 5. An assembly anti-detachment column 7 is installed inside the threaded blind hole of the operating ladder 5 to limit and prevent the protective opening ring 6 from detaching. The upper part of the assembly anti-detachment column 7 has a limiting circular plate to prevent the protective opening ring 6 from detaching upwards from the uprights of the operating ladder 5. The bottom end face of the limiting circular plate of the assembly anti-detachment column 7 has a threaded post for easy threaded installation. The top end face of the limiting circular plate of the assembly anti-detachment column 7 has a regular hexagonal groove for easy disassembly and assembly using tools. The bottom outer circumference of the uprights on both sides of the climbing ladder 5 is threaded with force-adjusting cylinders 8, which facilitate the downward movement of the force-adjusting cylinders 8 through thread engagement, allowing the ground-contacting rubber posts 9 to touch the ground. This disperses the force of operating the climbing ladder 5 to the ground. The inner circumference of the force-adjusting cylinder 8 is threaded, facilitating the raising and lowering adjustment of the force-adjusting cylinder 8 through thread engagement. The bottom outer circumference of the force-adjusting cylinder 8 is provided with a regular hexagonal structure, which facilitates the rotation of the force-adjusting cylinder 8 using tools. The ground-contacting rubber posts 9 are inserted into the bottom of the force-adjusting cylinder 8, facilitating contact and protection with the ground. The ground-contacting rubber posts 9 generate a certain elastic reaction force to prevent the force-adjusting cylinder 8 from loosening. The upper part of the ground-contacting rubber posts 9 is provided with an insertion post, facilitating the insertion of the ground-contacting rubber posts 9 into the force-adjusting cylinder 8. The bottom of the insertion post of the ground-contacting rubber posts 9 is provided with a ground-contacting disc, facilitating contact and protection between the ground-contacting rubber posts 9 and the ground.

[0023] The specific usage and function of this embodiment are as follows: In this invention, when the rotating sealing cover 4 is screwed into the inner threaded cylinder of the fermenter shell 2, the inverted truncated cone of the rotating sealing cover 4 presses into the conical annular groove of the rubber sealing gasket 3. This design increases the contact area and improves the locking degree, solving the problem of poor sealing effect caused by insufficient contact area between the sealing cover and the sealing gasket. When the operator climbs the operating ladder 5, the load on the operating ladder 5 is transferred to the ground through the force adjustment cylinder 8 and the ground-contacting rubber column 9, thereby reducing the load at the weld between the operating ladder 5 and the fermenter shell 2, reducing fatigue damage at the weld point, and solving the problem that the lower end of the ladder is suspended, causing the stress point to be at the weld between the fermenter and the ladder, which is prone to breakage. At the same time, when the operator climbs to the top of the operating ladder 5, the operator should be inside the protective opening ring 6, which allows the operator's back to be protected by the protective opening ring 6 to prevent the operator from falling backward, thus freeing up both hands to operate the top parts of the fermenter body 1.

[0024] Example 2: Unlike Example 1, the hexagonal prism of the rotating sealing cover 4 can also be set as a regular heptagonal prism, so that the rotating sealing cover 4 can only be rotated by a special tool that cooperates with the regular heptagonal prism, thus preventing non-staff members from rotating and disassembling the rotating sealing cover 4.

[0025] Example 3: The difference from Example 1 is that the regular hexagonal groove of the assembly anti-detachment column 7 can also be set as a regular heptagonal groove, so that the assembly anti-detachment column 7 can only be rotated by a special tool that cooperates with the regular heptagonal groove, thus preventing non-workers from rotating and disassembling the assembly anti-detachment column 7.
