Description

Technical Field

[0001] This invention relates to the field of fermentation equipment, and in particular to a sealing device for a liquor fermentation cellar. Background Technology

[0002] The sealing device for baijiu fermentation pits is a key piece of equipment used to seal the fermentation pits in the solid-state baijiu brewing process. Its design and application are of great significance for ensuring the fermentation quality, improving production efficiency, and maintaining product quality stability during the baijiu brewing process.

[0003] Traditionally, the sealed fermentation of baijiu (Chinese liquor) in cellars relies on a large amount of cellar mud and manual operation. This method is not only time-consuming and labor-intensive, but also prone to problems such as air leakage and poor fermentation, thus affecting the quality and yield of baijiu. Currently, stainless steel covers are also used for sealing, but due to the poor plasticity of stainless steel, the sealing effect at the bottom edge is not very good. It is necessary to reseal with cellar mud and plastic sheeting, which is not only troublesome to operate, but also has limited sealing effect.

[0004] Therefore, we use this technical solution to address the problem of poor sealing performance in existing cellar sealing devices. Summary of the Invention

[0005] The purpose of this invention is to improve upon existing cellar sealing devices. Compared to existing technologies, this invention provides a cellar sealing device for liquor fermentation pits. It seals the fermentation pit body by setting a sealing cover. The sealing cover and the fermentation pit body are pre-sealed by the insertion of a sealing ring into a sealing ring groove. Then, the weight of the sealing cover presses down on the elastic sealing membrane, allowing the sealing liquid in the squeezing chamber to enter the annular sealing gasket and expand. This further tightens the contact between the annular sealing gasket and the sealing ring, effectively improving the sealing effect. During fermentation, as the temperature rises, the heat-absorbing pad absorbs the generated heat and transfers it to the heat-absorbing mesh inside the annular sealing gasket through a heat-conducting wire. The heat-absorbing mesh expands after absorbing heat, further expanding the annular sealing gasket and creating an even tighter seal, thus further improving the sealing effect.

[0006] Furthermore, magnetic pads are fixedly connected to the inner walls of both the inner and outer elastic wrapping pads, and the two magnetic pads repel each other magnetically. When the sealing ring is inserted into the sealing ring groove, the annular sealing pad comes into close contact with the sealing ring to achieve a seal. The inner and outer magnetic pads repel each other, thereby allowing the inner magnetic pad to come into close contact with the sealing ring, thus effectively improving the sealing performance.

[0007] Optionally, a heat-absorbing mesh is placed inside the cavity, and a heat-absorbing pad is fixedly embedded in the upper inner wall of the sealing lid. A heat-conducting wire, which is fixedly connected to the heat-absorbing pad, is also fixedly embedded in the inner wall of the sealing lid. The lower end of the heat-conducting wire extends into the cavity and is fixedly connected to the heat-absorbing mesh. During fermentation, heat is generated, and the continuous accumulation of heat will affect the fermentation effect. The heat-absorbing pad is used to absorb the heat, and the heat is conducted to the heat-absorbing mesh through the heat-conducting wire. The heat-absorbing mesh absorbs heat and expands, thereby causing the annular sealing gasket to expand and make closer contact with the sealing ring, thus effectively improving the sealing effect.

[0008] Optionally, the heat-absorbing mesh has a mesh structure and is made of a heat-absorbing and expanding material. After absorbing heat, the heat-absorbing mesh expands to increase the volume of the annular sealing gasket, which then comes into closer contact with the sealing ring, thereby further improving the sealing effect. At the same time, the heat generated by the heat-absorbing mesh during fermentation can also effectively prevent the fermentation temperature from becoming too high.

[0009] Optionally, the squeezing chamber is also filled with a shaping mesh made of elastic material. The shaping mesh allows the elastic sealing membrane to maintain tension, so that after the sealing cover is pressed down, the elastic sealing membrane can make close contact with the upper surface of the fermentation tank body, thereby constructing an additional sealing line, which further improves the sealing performance.

[0010] Optionally, a water-absorbing expansion pad is also fixedly connected to the side wall of the inner elastic wrapping pad. The water-absorbing expansion pad is made of elastic material. Water vapor will be generated during the fermentation process. Water vapor is highly corrosive. In order to prevent water vapor from corroding the annular sealing gasket, a water-absorbing expansion pad is added to protect the annular sealing gasket. Moreover, the water-absorbing expansion pad can expand after absorbing water vapor, thereby further improving the sealing performance.

[0011] Compared with the prior art, the advantages of this invention are:

[0012] (1) This scheme seals the fermentation tank body by setting a sealing cover. The sealing cover and the fermentation tank body are pre-sealed by the insertion of the sealing ring and the sealing ring groove. Then, the sealing cover presses down on the elastic sealing membrane by its own weight, so that the sealing liquid in the squeezing chamber enters the annular sealing gasket and expands. The annular sealing gasket and the sealing ring are in closer contact, thereby effectively improving the sealing effect. During the fermentation process, when the temperature rises, the heat-absorbing pad absorbs the generated heat and transfers the heat to the heat-absorbing net inside the annular sealing gasket through the heat-conducting wire. After absorbing heat, the heat-absorbing net expands and becomes larger, so that the annular sealing gasket expands further and is more tightly connected to the sealing ring, thereby further effectively improving the sealing effect.

[0013] (2) The inner walls of the inner and outer elastic pads are fixedly connected with magnetic pads, and the two magnetic pads repel each other magnetically. When the sealing ring is inserted into the sealing ring groove, the annular sealing pad and the sealing ring are in close contact to achieve sealing. The inner and outer magnetic pads repel each other, so that the inner magnetic pad is in close contact with the sealing ring, thereby effectively improving the sealing performance.

[0014] (3) A heat-absorbing net is placed inside the cavity. A heat-absorbing pad is fixedly embedded in the upper inner wall of the sealing cap. A heat-conducting wire is fixedly embedded in the inner wall of the sealing cap and is fixedly connected to the heat-absorbing pad. The lower end of the heat-conducting wire penetrates into the cavity and is fixedly connected to the heat-absorbing net. Heat will be generated during fermentation. The continuous accumulation of heat will affect the fermentation effect. The heat-absorbing pad is used to absorb the heat and conduct the heat to the heat-absorbing net through the heat-conducting wire. The heat-absorbing net absorbs heat and expands, thereby expanding the annular sealing gasket and making it more closely contact the sealing ring, thus effectively improving the sealing effect.

[0015] (4) The heat-absorbing net is a mesh structure and the heat-absorbing net is made of heat-absorbing and expanding material. After the heat-absorbing net absorbs heat, it expands to increase the volume of the annular sealing gasket. The annular sealing gasket then comes into closer contact with the sealing ring, thereby further improving the sealing effect. At the same time, the heat generated by the heat-absorbing net during fermentation can also effectively prevent the fermentation temperature from being too high.

[0016] (5) The squeezing chamber is also filled with a plastic mesh, which is made of elastic material. The plastic mesh can keep the elastic sealing membrane under tension, so that after the sealing cover is pressed down, the elastic sealing membrane can make close contact with the upper surface of the fermentation tank body, thereby constructing an additional sealing line, which further improves the sealing performance.

[0017] (6) A water-absorbing expansion pad is also fixedly connected to the side wall of the inner elastic wrapping pad. The water-absorbing expansion pad is made of elastic material. Water vapor will be generated during the fermentation process. Water vapor is highly corrosive. In order to prevent water vapor from corroding the annular sealing gasket, a water-absorbing expansion pad is added to protect the annular sealing gasket. Moreover, the water-absorbing expansion pad can expand after absorbing water vapor, thereby further improving the sealing performance. Attached Figure Description

[0027] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Please refer to a sealing device for a liquor cellar. Figure 1 , 2 and Figure 4 The fermentation tank body 1 includes a sealing ring 2 fixedly connected to the upper side wall of the fermentation tank body 1. The fermentation tank body 1 is covered with a sealing cover 3. The lower side wall of the sealing cover 3 is provided with a sealing ring groove 301 that matches the sealing ring 2. The upper end of the sealing cover 3 is equipped with a one-way exhaust pipe 9 and a sampling window 10. The sampling window 10 is sealed to the upper side wall of the sealing cover 3. The inner wall of the sealing ring groove 301 is fixedly connected with an annular sealing gasket 4. The lower side walls of the sealing cover 3 on both sides of the sealing ring groove 301 are provided with squeezing chambers 302. The squeezing chambers 302 are connected to a liquid passage pipe 303 that communicates with the inside of the annular sealing gasket 4.

[0029] Please see Figure 3 , 5 and Figure 6The annular sealing gasket 4 includes two layers of elastic wrapping gaskets 401, with the two layers of elastic wrapping gaskets 401 forming a closed cavity 402. Magnetic pads 403 are fixedly connected to the inner walls of both the inner and outer elastic wrapping gaskets 401, and the two magnetic pads 403 repel each other magnetically. When the sealing ring 2 is inserted into the sealing ring groove 301, the annular sealing gasket 4 comes into close contact with the sealing ring 2 to achieve a seal. The inner and outer magnetic pads 403 repel each other, thus allowing the inner magnetic pad 403 to come into close contact with the sealing ring 2, thereby effectively improving the sealing performance. The squeezing chamber 302, the liquid passage 303, and the cavity 402 are all filled with sealing liquid, and an elastic sealing membrane 5 is fixedly connected to the lower opening of the squeezing chamber 302.

[0030] Based on Example 1, please refer to Figure 2 , 7 Inside the cavity 402, a heat-absorbing mesh 404 is placed. The heat-absorbing mesh 404 has a mesh structure and is made of a heat-absorbing and expanding material. After absorbing heat, the heat-absorbing mesh 404 expands to increase the volume of the annular sealing gasket 4. The annular sealing gasket 4 then comes into closer contact with the sealing ring 2, thereby further improving the sealing effect. At the same time, the heat generated by the heat-absorbing mesh 404 during fermentation can also effectively prevent the fermentation temperature from becoming too high. A heat-absorbing pad 7 is fixedly embedded in the upper inner wall of the sealing cover 3, and a heat-conducting wire 8 is fixedly embedded in the inner wall of the sealing cover 3 and is fixedly connected to the heat-absorbing pad 7. The lower end of the heat-conducting wire 8 penetrates into the cavity 402 and is fixedly connected to the heat-absorbing mesh 404. During the fermentation process, heat is generated. The continuous accumulation of heat will affect the fermentation effect. Therefore, the heat-absorbing pad 7 is used to absorb the heat, and the heat is conducted to the heat-absorbing mesh 404 through the heat-conducting wire 8. The heat-absorbing mesh 404 absorbs heat and expands, thereby causing the annular sealing gasket 4 to expand and come into closer contact with the sealing ring 2, thereby effectively improving the sealing effect.

[0031] Please see Figure 4 The squeezing chamber 302 is also filled with a plastic mesh 6, which is made of elastic material. The plastic mesh 6 can keep the elastic sealing membrane 5 under tension, so that after the sealing cover 3 is pressed down, the elastic sealing membrane 5 can make close contact with the upper surface of the fermentation tank body 1, thereby constructing an additional sealing line, which further effectively improves the sealing performance.

[0032] Please see Figure 6 The inner elastic wrapping pad 401 is also fixedly connected to the side wall of a water-absorbing expansion pad 11. The water-absorbing expansion pad 11 is made of elastic material. Water vapor will be generated during fermentation. Water vapor is highly corrosive. In order to prevent water vapor from corroding the annular sealing gasket 4, a water-absorbing expansion pad 11 is added to protect the annular sealing gasket 4. Moreover, the water-absorbing expansion pad 11 can expand after absorbing water vapor, thereby further improving the sealing performance.

[0033] The working principle of this scheme is as follows: When sealing the cellar, the sealing cover 3 is placed over the sealing ring 2, and the sealing ring 2 is inserted into the sealing ring groove 301. The inner and outer magnetic pads 403 repel each other, so that the inner magnetic pad 403 is in close contact with the sealing ring 2, thereby effectively improving the sealing performance. After the sealing cover 3 is placed on, the elastic sealing membrane 5 is pressed down by its own weight. The elastic sealing membrane 5 squeezes the sealing liquid inside the squeezing chamber 302 into the cavity 402. The annular sealing gasket 4 further expands and becomes larger, thereby further improving the sealing performance. During the fermentation process, heat is generated. The continuous accumulation of heat will affect the fermentation effect. Therefore, the heat-absorbing pad 7 is used to absorb the heat, and the heat is conducted to the heat-absorbing net 404 through the heat-conducting wire 8. The heat-absorbing net 404 absorbs heat and expands, thereby causing the annular sealing gasket 4 to expand and further contact the sealing ring 2, thereby effectively improving the sealing effect.

[0034] The above description is only the best implementation method adopted by the present invention in combination with current practical needs, but the scope of protection of the present invention is not limited thereto.
