Description

Technical Field

[0001] This utility model relates to the field of liquor brewing technology, and in particular to a cellar sealing system. Background Technology

[0002] Maotai-flavor baijiu is renowned both domestically and internationally for its complex brewing process and rich aroma components. The production process of Maotai-flavor baijiu can be summarized as follows: making koji (fermentation starter) around the Dragon Boat Festival, adding raw materials (two additions) around the Double Ninth Festival, nine distillations, eight fermentations, seven extractions, and multiple additions of koji (the amount of koji added is increased in the first and second rounds, appropriately increased in the third, fourth, and fifth rounds, and reduced as needed in the seventh and eighth rounds. The ratio of total koji added to total raw materials in each round is approximately 1:1. Specifically, this means 11% raw koji, 18% coarse koji, 13% in rounds 3 and 4, 11% in round 5, 7% in round 6, 6% in round 7, and 5% in round 8). The two additions refer to the initial addition of raw materials (50% of the total raw materials) and the addition of coarse koji (50% of the total raw materials). Each fermentation lasts about one month, with a total cycle of approximately 10 months.

[0003] Because koji powder and rice husks are added to the mash before it enters the fermentation pit, the amount of raw material entering the pit for each subsequent fermentation cycle is greater than the previous cycle. Since the pit volume is fixed, the height of the material in each subsequent cycle is greater than the previous cycle. Fermentation in the pit is anaerobic, so it is essential to ensure complete isolation of the mash from the outside air. The current method involves manually covering the mash with pit mud for sealing, which has disadvantages such as high labor intensity, high technical requirements, cumbersome post-construction maintenance and inspection, long operation cycle, and high pit treatment costs.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] In the description of the embodiments of this utility model, it should be noted that, unless otherwise expressly specified and limited, the terms "first" and "second" are numbered for the purpose of clearly identifying product components and do not represent any substantial difference. The terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model according to the specific circumstances. Furthermore, "multiple" means two or more.

[0038] The following combination Figures 1-7 This invention describes the cellar sealing system.

[0039] like Figure 1 and Figure 2 As shown, the cellar sealing system provided in this embodiment of the present invention includes an inflation pipeline 1, multiple air pressure control devices 2, and multiple sealing devices 3. Each sealing device 3 includes a main frame 31 and an airbag 32, with the airbag 32 surrounding the outside of the main frame 31 and fixedly connected to it. The inflation pipeline 1 is connected to the airbag 32 and is used to inflate the airbag 32. The air pressure control devices 2 are disposed on the inflation pipeline 1 and correspond one-to-one with the multiple airbags 32, used to adjust and control the air pressure inside the airbags 32, so that when the main frame 31 is placed inside the cellar 5, the airbags 32 are sealed tightly against the inner wall of the cellar 5.

[0040] Multiple sealing devices 3 are used to seal multiple pits 5 in a one-to-one correspondence. The shape of the main frame 31 is the same as the shape of the opening of the pit 5, and the size of the main frame 31 is slightly smaller than the shape of the opening of the pit 5. Usually, the opening of the pit 5 is cuboid, with a rectangular opening and four vertical planes on its four inner walls. Correspondingly, the sealing device 3 is also rectangular in structure, and its surrounding air bladders 32 are sealed and fitted tightly to the four inner walls of the pit 5. Of course, the main frame 31 can also be circular, square, or other shapes, and there is no specific limitation.

[0041] The main frame 31 includes a frame body and an isolation layer. Airbags 32 surround the outside of the frame body, and the isolation layer is laid on the frame body. The isolation layer and airbags 32 are sealed together to isolate the inside and outside of the pit 5. The frame body includes an outer frame and multiple horizontal and vertical bars fixed inside the outer frame. For example, the outer frame is rectangular, with multiple horizontal bars spaced apart along the length of the outer frame and multiple vertical bars spaced apart along the width of the outer frame, forming a structurally stable frame body.

[0042] When it is necessary to seal the pit 5, the airbag 32 is deflated, so that the horizontal dimension of the sealing device 3 is smaller than the dimension of the pit 5. The sealing device 3 can be inserted into the pit 5 from top to bottom, and the main frame 31 can approach or fit against the material inside the pit 5. Then, the airbag 32 is inflated, so that the airbag 32 gradually seals against the inner wall of the pit 5, achieving a sealed isolation between the inside and outside of the pit 5. When it is necessary to open the pit 5 to refill, the airbag 32 is first deflated, and the supporting force between the airbag 32 and the inner wall of the pit 5 disappears. Then, the sealing device 3 is removed from the pit 5 from bottom to top.

[0043] When sealing multiple pits 5 using this pit sealing system, the air bladders 32 of the multiple sealing devices 3 are inflated through the inflation pipe 1. Simultaneously, multiple pressure control devices 2 on the inflation pipe 1 control the pressure of each air bladder 32 to ensure a tight seal between each air bladder 32 and the inner wall of its corresponding pit 5. When it is necessary to open a specific pit 5 and deflate the air bladder 32, the pressure of the other air bladders 32 is maintained by the corresponding pressure control devices 2 without being affected.

[0044] The pit sealing system provided in this embodiment of the invention, by setting up an inflation pipeline 1, an air pressure control device 2, and multiple sealing devices 3, allows for the simultaneous inflation of the air bladders 32 of multiple sealing devices 3 through the inflation pipeline 1, thereby achieving simultaneous sealing of multiple pits 5. The multiple air pressure control devices 2 control the air supply to the multiple air bladders 32 one-to-one, ensuring that each air bladder 32 can seal tightly against the inner wall of its corresponding pit 5, while the deflation of each sealing device 3 does not interfere with each other. The pit sealing system provided in this embodiment simplifies the inflation and deflation process of the multiple sealing devices 3, facilitates pit feeding, reduces labor intensity, lowers worker skill requirements, facilitates subsequent maintenance and inspection, shortens the operation cycle, and reduces pit treatment costs.

[0045] The cellar sealing system provided in this embodiment of the present invention also includes a gas storage device 4. The gas outlet of the gas storage device 4 is connected to multiple air bags 32 through an inflation pipeline 1. A first pressure reducing valve 42 is provided on the inflation pipeline 1 for adjusting and controlling the outlet gas pressure of the gas storage device 4.

[0046] The gas stored in the gas storage device 4 is compressed gas. The first pressure reducing valve 42 is installed on the inflation pipeline 1 to detect the real-time pressure of the compressed air output from the gas storage device 4 to the inflation pipeline 1. By adjusting the opening of the first pressure reducing valve 42, the pressure and flow rate of the compressed air entering the inflation pipeline 1 are adjusted and controlled to ensure that the pressure in the inflation pipeline 1 is within a safe range and can reach the farthest sealing device 3, thus ensuring the safety of gas delivery and the stable operation of the system.

[0047] Optionally, the first pressure reducing valve 42 is an electronic pressure reducing valve, which can automatically start and stop according to a first set pressure range. When the air pressure in the inflation line 1 is lower than the first set air pressure, the first pressure reducing valve 42 opens; when the air pressure in the inflation line 1 is higher than the second set air pressure, the first pressure reducing valve 42 closes. The first set air pressure is lower than the second set air pressure.

[0048] Furthermore, the air inlet of the air storage device 4 is connected to an air inlet pipe, and a first one-way valve 41 is installed on the air inlet pipe. The air inlet pipe is used to connect to the air supply device to periodically inflate the air storage device 4. The gas in the air inlet pipe enters the air storage device 4 through the first one-way valve 41, which controls the unidirectional flow of compressed air into the air storage device 4, preventing it from escaping from the air inlet of the air storage device 4. By controlling the overall capacity of the air storage device 4 and using the first one-way valve 41, a certain buffer time can be ensured for the air bladder 32 to supply air when the front-end air compressor is shut down for mechanical maintenance.

[0049] Optionally, a pneumatic valve 43 is provided on the inflation line 1 to automatically control the opening and closing of the air outlet of the air storage device 4. This enables remote control of the airflow within the inflation line 1, improving the convenience and flexibility of operation.

[0050] Optionally, the gas storage device 4 is equipped with a pressure relief valve 45. When the gas pressure in the gas storage device 4 is too high and exceeds the set pressure of the pressure relief valve 45, the pressure relief valve 45 will automatically open to release some gas and ensure that the gas pressure in the gas storage device 4 is below the set pressure.

[0051] like Figure 2 As shown in the embodiment of this utility model, the inflation pipeline 1 includes a main air supply pipeline 11 and multiple branch pipelines 12. The multiple branch pipelines 12 are respectively connected to the main air supply pipeline 11. Multiple airbags 32 are connected to each branch pipeline 12, and a pressure control device 2 is provided at the air inlet of each airbag 32. Optionally, one end of the main air supply pipeline 11 is connected to the air outlet of the air storage device 4, and the other end is connected to the multiple branch pipelines 12.

[0052] Specifically, the gas in the main gas supply pipe 11 is diverted into multiple branch pipes 12, each branch pipe 12 being connected to multiple airbags 32. The branch pipes 12 can be arranged according to the distribution of the multiple storage pits 5. See also Figure 1 and Figure 3 The fermentation site has multiple rows of pits 5, and the sealing device 3 of each row or multiple rows of pits 5 is connected to the main gas supply pipe 11 through a branch pipe 12.

[0053] Each branch pipe 12 may include one secondary main pipe and multiple secondary branch pipes 121. The multiple secondary branch pipes 121 are connected to the main gas supply pipe 11 via the secondary main pipe. Each secondary branch pipe 121 is correspondingly connected to the sealing device 3 of a row of storage pits 5. For example... Figure 3 As shown, a branch pipe 12 includes a secondary main pipe and two secondary branch pipes 121.

[0054] like Figure 5 As shown in the embodiment of this utility model, the air pressure control device 2 includes an air pipe 21 and a second pressure reducing valve 22. Each airbag 32 is connected to a branch pipe 12 through the air pipe 21. The second pressure reducing valve 22 is installed on the air pipe 21 and is used to adjust and control the air intake pressure of the airbag 32.

[0055] The second pressure reducing valve 22 is installed on the air pipe 21 to detect the real-time pressure of the compressed air output from the branch pipe 12 into the air pipe 21. By adjusting the opening of the second pressure reducing valve 22, the pressure and flow of the air entering the air bag 32 are adjusted and controlled to ensure the minimum air pressure in the air bag 32, thereby ensuring that the sealing device 3 is sealed and fitted to the inner wall of the pit 5.

[0056] Optionally, the second pressure-reducing valve 22 is an electronic pressure-reducing valve, which can automatically start and stop according to the second set pressure range. When the air pressure inside the airbag 32 is lower than the third set air pressure, the second pressure-reducing valve 22 opens to replenish the airbag 32; when the air pressure inside the airbag 32 is higher than the fourth set air pressure, the second pressure-reducing valve 22 closes to prevent excessive air pressure inside the airbag 32 from causing an explosion. The third set air pressure is lower than the fourth set air pressure.

[0057] In some embodiments of this utility model, the sealing device 3 further includes a pressure sensor 33, which is disposed on the main body frame 31 and is used to detect the air pressure inside the airbag 32. The pressure sensor 33 is communicatively connected to the second pressure reducing valve 22.

[0058] Specifically, the cellar sealing system also includes a controller, with a pressure sensor 33 and a second pressure-reducing valve 22 communicatively connected to the controller. The main frame 31 has a hollow cavity communicating with the air bladder 32. The pressure sensor 33 detects the pressure inside the air bladder 32 in real time and sends the detected pressure value to the controller. The controller compares this pressure value with a second set pressure range. When the pressure value is less than the second set pressure range, the controller controls the second pressure-reducing valve 22 to open; when the pressure value is greater than the second set pressure range, the controller controls the second pressure-reducing valve 22 to close.

[0059] In this embodiment, the opening and closing of the corresponding second pressure reducing valve 22 can be controlled according to the pressure value detected by the pressure sensor 33 of each sealing device 3, so as to ensure that the airbag 32 of each sealing device 3 works within the second set pressure range, that is, to ensure the minimum pressure inside the airbag 32 to ensure its sealing performance, and to ensure that the airbag 32 works under a safe pressure.

[0060] like Figure 5 As shown, in some embodiments of this utility model, the air pressure control device 2 further includes a second one-way valve 23. The second one-way valve 23 is disposed on the air pipe 21, and the gas in the air pipe 21 enters the airbag 32 through the second one-way valve 23. The second one-way valve 23 controls the one-way flow of compressed air into the airbag 32. When the front-end air circuit or equipment malfunctions or manual intervention is required, the second one-way valve 23 can effectively ensure the sealing function of the airbag 32. Optionally, the second one-way valve 23 is located between the second pressure reducing valve 22 and the airbag 32.

[0061] Optionally, such as Figure 2As shown, the cellar sealing system also includes a first manual shut-off valve 44. The first manual shut-off valve 44 is installed on the air supply pipeline 1 and is used to manually open and close the air outlet of the air storage device 4. Specifically, the first manual shut-off valve 44 is located on the main air supply pipeline 11. In the event of a failure of the pneumatic valve 43 or the need for manual intervention, the first manual shut-off valve 44 is manually operated to open and close the air outlet of the air storage device 4. Optionally, the pneumatic valve 43 is located between the air storage device 4 and the first manual shut-off valve 44, and the first pressure reducing valve 42 is located on the side of the first manual shut-off valve 44 away from the pneumatic valve 43.

[0062] Optionally, such as Figure 6 As shown, the cellar sealing system also includes a second manual shut-off valve 122, which is installed on the branch pipeline 12. In the event of an abnormality in the upstream gas circuit or equipment, the gas supply from the main gas supply pipeline 11 to the branch pipeline 12 can be cut off through the second manual shut-off valve 122.

[0063] Optionally, the pit sealing system also includes a third manual shut-off valve 24, which is located on the air pipe 21. In the event of an abnormality in the upstream air path or equipment, the third manual shut-off valve 24 can cut off the air supply from the branch pipe 12 to the airbag 32. Optionally, the second one-way valve 23 is located between the second pressure reducing valve 22 and the airbag 32, and the third manual shut-off valve 24 is located on the side of the second pressure reducing valve 22 away from the second one-way valve 23.

[0064] like Figure 7 As shown in the embodiment of this utility model, the sealing device 3 further includes a level 34 and a plurality of adjusting straps 351. The level 34 is disposed on the main body frame 31. One end of each adjusting strap 351 is connected to the main body frame 31, and the connection points of the plurality of adjusting straps 351 to the main body frame 31 are centrally symmetrical about the center of the main body frame 31. Optionally, the level 34 is a bidirectional level and is disposed in the middle region of the main body frame 31.

[0065] When sealing the pit 5, first inflate the airbag 32 to make it adhere to the inner wall of the pit 5, but before it is completely sealed, adjust the sealing device 3 in multiple directions by pulling multiple adjusting straps 351 according to the status of the sealing device 3 displayed on the level instrument 34, until the level instrument 34 shows that the sealing device 3 is horizontal. Then continue to inflate the airbag 32 to make it tightly adhere to the inner wall of the pit 5 and seal it.

[0066] The connection points of multiple adjustment bands 351 to the main frame 31 are arranged symmetrically about the center of the main frame 31. This facilitates the correction of the posture of the sealing device 3 at mutually symmetrical positions, allowing the sealing device 3 to quickly reach a horizontal state. For example, there are four adjustment bands 351. Two adjustment bands 351 are provided on each of the two long sides of the rectangular sealing device 3, and the adjustment bands 351 on the two long sides are symmetrically arranged about the center line of the sealing device 3.

[0067] Optionally, the main frame is provided with a first lifting ring, and one end of each adjusting belt 351 is connected to the main frame 31 through a first lifting ring. The other end of the adjusting belt 351 can be suspended in the air or tied to the fixing parts around the pit 5. This can ensure that the sealing device 3 is in a horizontal state and prevent the sealing device 3 from tilting and causing the seal to fail.

[0068] Optionally, such as Figure 1 and 7 As shown, the sealing device 3 also includes multiple fixing seats 352, with each fixing seat 352 and multiple adjusting belts 351 corresponding to each other. The fixing seats 352 are suitable for fixing to the pit 5, and the other end of the adjusting belts 351 is detachably connected to the fixing seats 352. The multiple fixing seats 352 can be directly fixed to the pit 5 and arranged around the sealing device 3.

[0069] After adjusting the sealing device 3 to a horizontal position using the adjusting belt 351, the other end of the adjusting belt 351 is bound to the fixed base 352 to ensure that the sealing device 3 is in a horizontal position. When it is necessary to open the pit 5, the adjusting belt 351 is unbound from the fixed base 352. Optionally, the adjusting belt 351 is mounted on the main frame 31 by an automatic winding mechanism, and can be automatically wound up after the adjusting belt 351 is unbound from the fixed base 352.

[0070] In this embodiment of the invention, the sealing device 3 further includes a plurality of hanging chains 36, which are centrally symmetrically arranged about the center of the main body frame 31. Each hanging chain 36 has a first connecting end 361, a second connecting end 362, and a hanging part 363. The first connecting end 361 and the second connecting end 362 are respectively connected to the main body frame 31, and the hanging part 363 is located at the exact center of the first connecting end 361 and the second connecting end 362. Optionally, the main body frame 31 is provided with a second hanging ring, and the first connecting end 361 and the second connecting end 362 are respectively connected to the main body frame 31 through a second hanging ring.

[0071] As a specific example, the main frame 31 has a rectangular structure, with a lifting chain 36 on each of its two long sides, symmetrical about the center line of the main frame 31 along its length. A first connecting end 361 and a second connecting end 362 are spaced apart on the long sides of the main frame 31, symmetrical about the center line of the main frame 31 along its width. A hanging part 363 corresponds to the midpoint of the long side of the main frame 31. When transferring the sealing device 3, the hanging parts 363 of the two lifting chains 36 can be connected to a lifting device, and the sealing device 3 can be raised or lowered using the lifting device.

[0072] In this embodiment, the sealing device 3 is transported using multiple lifting chains 36. This allows the sealing device 3 to remain relatively horizontal during transport, reducing subsequent adjustments and improving the efficiency of the sealing operation of the pit 5. The number and distribution of the lifting chains 36 can be set according to the shape and size of the sealing device 3, and are not limited here.

[0073] In this embodiment of the invention, the sealing device 3 further includes a heat insulation layer 37 and a temperature detection device 38. The heat insulation layer 37 is disposed on the main frame 31. The heat insulation layer 37 is used to isolate the temperature difference between the inside and outside of the fermentation pit 5, preventing condensation from forming on the inner surface of the sealing device 3 and affecting fermentation. The temperature detection device 38 is disposed on the main frame 31 and is used to detect the temperature of the mash inside the fermentation pit 5 and the ambient temperature outside the fermentation pit. The temperature detection device 38 can be a temperature measuring rod or other temperature sensor.

[0074] Specifically, a sensor interface is provided on the main frame 31, and a temperature detection device 38 passes through the sensor interface to enter below the sealing device 3 to detect the temperature of the fermented mash below the sealing device 3. The temperature detection device 38 includes two detection probes, one for detecting the temperature inside the fermentation pit 5 and the other for detecting the ambient temperature outside the fermentation pit. This allows for monitoring of fermentation based on the temperature inside the fermentation pit 5 and the ambient temperature outside the fermentation pit.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
