Description

Technical Field

[0001] The invention belongs to the technical field of sour soup storage, in particular to a storage fermentation tank. Background Art

[0002] A storage fermentation tank is a container specially designed for storing fermented products (such as wine, dairy products, biological agents, etc.). It can not only effectively isolate the invasion of external impurities and microorganisms, but also maintain the storage conditions required by the product through its internal structure and control system to ensure the quality and stability of the product. When storing sour soup fermentation, special storage fermentation tanks are used to store the sour soup to maintain its quality.

[0003] The traditional storage fermentation tank is mainly composed of a tank body, a feed port and a pressure relief port. When in use, sour soup is added through the feed port, and the feed port is also used to discharge when it needs to be taken out. In order to prevent the sour soup from overflowing when adding and to facilitate adding, the feed port is usually set at a position higher than the bottom of the tank body. However, the use of such a feed port will result in a certain distance from the bottom of the tank body, making it difficult to discharge the sour soup at the bottom. At the same time, the sour soup gathers at the bottom and is prone to adhesion, affecting the storage effect.

[0004] Since the sour soup will be stored and fermented inside the tank, a certain amount of fermentation gas will be generated during long-term fermentation. In the prior art, a pressure relief valve is provided to prevent the tank from bursting due to excessive pressure. When the pressure is too high, the pressure relief valve can be opened to relieve the pressure. However, the fluidity of the sour soup is relatively high. The traditional pressure relief method can easily cause the sour soup to overflow to the pressure relief valve and cause the pressure relief valve to be blocked. It is impossible to ensure normal pressure relief when the pressure is too high to keep the tank stable. This poses a great safety hazard and is in urgent need of improvement. Summary of the invention

[0005] The object of the present invention is to provide a storage fermentation tank to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a storage fermentation tank, comprising a fermentation tank assembly, a frame is fixedly installed on the right end of the outer side of the fermentation tank assembly, a gas quantitative assembly is fixedly sleeved inside the frame, the top of the gas quantitative assembly is connected to the right side of the fermentation tank assembly, a feed control assembly is installed at a position near the bottom of the inner cavity of the fermentation tank assembly, a three-way valve is fixedly connected at a position near the top of the right side of the gas quantitative assembly, a pressure relief flap valve is fixedly connected at the top of the three-way valve, an auxiliary flap valve is fixedly connected at the bottom of the three-way valve, a gas pipeline is fixedly connected at the bottom of the auxiliary flap valve, and the other end of the gas pipeline passes through the outer side of the fermentation tank assembly and is connected to the feed control assembly;

[0007] The fermentation tank assembly includes a storage tank, the bottom end of the inner cavity of the storage tank is movably sleeved with a movable bottom plate, the left side of the storage tank is fixedly connected with a material port located above the movable bottom plate, the inner side surface of the material port is provided with a sealing groove, the right side of the storage tank is provided with a through hole, one end of the gas pipe passes through the through hole and is connected with a feed control assembly, the bottom end of the feed control assembly is connected to the middle part of the top of the movable bottom plate, the right side of the storage tank is provided with an exhaust hole located above the gas quantitative assembly, and the other end of the exhaust hole is connected with the gas quantitative assembly.

[0008] In the initial state, the feed control component can completely seal the fermentation tank component. At this time, the device is in a sealed state. Before storing the sour soup, it is necessary to ensure that there is no sour soup remaining inside the feed port and inside the storage tank. Ensure the cleanliness of the inside of the storage tank and complete the preparation before storing the sour soup.

[0009] As a further technical solution of the present invention, a sealing top plate located above the exhaust hole is fixedly installed at the top of the inner cavity of the storage tank, and an inverted frustum-shaped groove is formed at the top of the movable bottom plate.

[0010] Among them, the space between the sealed top plate and the movable bottom plate is the maximum storage space of the storage tank. During storage, the maximum liquid level of the stored sour soup must not contact the sealed top plate. At the same time, the overall sour soup liquid level should be controlled at the bottom of the exhaust hole to ensure that the sour soup will not overflow.

[0011] As a further technical solution of the present invention, the feed control assembly includes a fixed tube, the right end of the fixed tube is connected to the right end of the inner side of the storage tank, the internal movable sleeve of the fixed tube is provided with a movable plate, the right end of the movable plate is fixedly connected to a return spring located inside the fixed tube, and the other end of the return spring is connected to the right end of the inner cavity of the fixed tube.

[0012] As a further technical solution of the present invention, an intake valve is fixedly connected to the outer side of the fixed tube near the left end, and the other end of the intake valve is connected to the air supply pipe. When the return spring is in the initial state, the movable plate is located on the right side of the intake valve input end.

[0013] As a further technical solution of the present invention, the end of the movable plate away from the reset spring is fixedly connected to a movable rod, the movable rod passes through the left side of the fixed tube and is fixedly connected to a sealing plug located inside the material port, the sealing plug is movably connected to the material port, and when the movable plate is located at the leftmost side, that is, when the reset spring is in an initial state, the left side of the sealing plug is movably clamped to the sealing groove.

[0014] As a further technical solution of the present invention, a linkage frame is fixedly sleeved on the outer side surface of the movable rod, a first fixing seat is fixedly installed on the right side of the bottom end of the linkage frame, and the first fixing seat is located directly below the fixing pipe.

[0015] As a further technical solution of the present invention, one end of the first fixed seat away from the linkage frame is movably connected to a connecting rod via a rotating shaft, and one end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat via a rotating shaft. The bottom end of the second fixed seat is connected to the middle part of the top end of the movable bottom plate. When the sealing plug is movably engaged with the sealing groove, the movable bottom plate is at the lowest point, that is, the bottom end of the movable bottom plate is in contact with the bottom end of the inner cavity of the storage tank.

[0016] When it is necessary to add sour soup to the interior of the storage tank, pressure can be applied to the sealing plug toward the right side, so that the sealing plug is displaced to the right side, at which time the movable plate can be driven to displace toward the right side and the reset spring can be compressed. At this time, the sealing plug can be displaced relative to the material port. When the sealing plug is completely displaced to the interior of the storage tank, a gap can be generated between the sealing plug and the storage tank, and the sour soup can then be input through the material port and enter the interior of the storage tank from the gap, thereby completing the injection of the sour soup. Alternatively, the sour soup can be directly pressurized, and the pressure of the sour soup can be used to achieve the displacement of the sealing plug to the interior of the storage tank, thereby completing the direct injection process of the sour soup. After the injection is completed, the pressure applied to the sealing plug can be stopped, and at this time the reset spring can automatically reset, thereby driving the movable plate and the sealing plug to automatically reset, until the sealing plug is completely engaged with the sealing groove, thereby realizing the self-sealing process.

[0017] When feeding and discharging the sour soup, it is necessary to apply pressure to the sealing plug and make it enter the interior of the storage tank. When the sealing plug moves to the right, it can synchronously drive the movable rod and the linkage frame to move. At this time, the first fixed seat moves to the right accordingly, and drives the connecting rod to deflect. At this time, the second fixed seat is subjected to a pulling force to the right, which can pull the movable bottom plate to move upward, so that the top of the movable bottom plate is close to the material port, which is convenient for the feeding and discharging process of the sour soup. When the device completes self-sealing and stops injecting material, the sealing plug automatically resets to the left, which can drive the movable bottom plate to move downward and restore to the initial state.

[0018] By utilizing the pressure during injection to achieve the displacement of the sealing plug, the device can only inject material under the action of pressure. At the same time, it can automatically achieve sealing when the injection is stopped. The movable bottom plate can automatically rise when the injection can be discharged, reducing the distance between the bottom end of the device and the feeding position, making it easier to feed and discharge. At the same time, the up and down displacement of the movable bottom plate can also reduce the accumulation of sour soup at the bottom, avoid adhesion caused by aggregation, and improve storage effect and feeding and discharging efficiency.

[0019] As a further technical solution of the present invention, the gas quantitative assembly includes a quantitative tank, the outer side surface of the quantitative tank is fixedly connected to the frame, the top of the quantitative tank is fixedly connected with a bent pipe, the other end of the bent pipe is fixedly connected to the exhaust hole, and the right side of the quantitative tank near the top is connected to the three-way valve.

[0020] When the internal fermentation gas of the storage tank is too large and the fermentation gas temporarily stored in the quantitative tank is full, as the pressure increases, the fermentation gas can enter the interior of the three-way valve and exert pressure on the pressure relief flap valve and the auxiliary flap valve. The pressure flap valve is then opened, and part of the fermentation gas can be automatically discharged through the pressure relief flap valve. At the same time, part of the fermentation gas can be input into the interior of the fixed pipe through the auxiliary flap valve and the gas pipe, and push the movable plate to move to the right. At this time, the sealing plug moves to the right, the material port is opened, and the movable bottom plate moves upward under the action of the connecting rod, and the sour soup inside the storage tank is then discharged through the material port, reducing the sour soup inside the storage tank, until the fermentation gas returns to the normal pressure level, the fermentation gas inside the feed control component is discharged, the feed control component automatically resets, and the discharge of the sour soup is automatically stopped.

[0021] By utilizing the gas generated during fermentation, that is, when the fermentation gas pressure is too high, the fermentation gas is introduced into the interior of the feed control component, and the feed port is automatically opened through the action of the feed control component, so the sour soup is automatically discharged, and the automatic pressure relief of the pressure relief flap valve is coordinated, so that the sour soup will not overflow and cause blockage during the pressure relief, thereby ensuring the normal pressure relief and avoiding safety accidents caused by material blockage during the pressure relief, thereby significantly improving the safety of the device.

[0022] As a further technical solution of the present invention, a quantitative plate is provided inside the quantitative tank, and a card slot is opened on both sides of the inner cavity of the quantitative tank near the bottom. The quantitative plate is movably connected between the card block and the card slot, and the quantitative plate moves up and down relative to the card slot.

[0023] As a further technical solution of the present invention, a screw is movably connected to the middle of the bottom end of the quantitative plate, a threaded sleeve is fixedly installed to the middle of the bottom end of the quantitative tank, and the outer side surface of the screw is threadedly connected to the inner side surface of the threaded sleeve.

[0024] When the injection of sour soup is completed, the gas metering component can be adaptively adjusted according to the injection amount of sour soup. When the injection amount of sour soup is small, the metering plate can be driven upward by rotating the screw under the action of the threaded sleeve and the guiding action of the slot, that is, the distance between the top of the inner cavity of the metering tank and the top of the metering plate is reduced. At this time, the amount of gas that can be stored in the metering tank is reduced. Conversely, when the injection amount of sour soup is large, the metering plate can be displaced downward to increase the distance between the top of the inner cavity and the top of the metering plate, thereby increasing the amount of gas that can be stored in the metering tank and completing the adaptive adjustment process.

[0025] By setting a quantitative plate that can be moved up and down and cooperating with the rotation of the screw, the volume inside the quantitative tank can be adaptively adjusted, so that the device can adjust the maximum amount of fermented gas that can be temporarily stored according to different amounts of sour soup, so that the device can temporarily store the fermented gas under different sour soup storage conditions, and automatically release the pressure when the fermented gas exceeds a predetermined pressure, further improving the safety of the device during sour soup fermentation.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The present invention realizes the displacement of the sealing plug by utilizing the pressure effect during injection, so that the device can inject material only under the action of pressure, and can automatically realize sealing when the injection is stopped, and can automatically realize the automatic rise of the movable bottom plate when the injection and discharge are possible, thereby reducing the distance between the bottom end of the device and the feeding position, making it easy to feed and discharge the material. At the same time, the up and down displacement of the movable bottom plate can also reduce the accumulation of sour soup at the bottom, avoid the adhesion phenomenon caused by aggregation, and improve the storage effect and the feeding and discharging efficiency.

[0028] 2. The present invention utilizes the gas generated during fermentation. That is, when the fermentation gas pressure is too high, the fermentation gas is introduced into the interior of the feed control component, and the feed port is automatically opened through the action of the feed control component, so the sour soup is automatically discharged, and the automatic pressure relief of the pressure relief flap valve is coordinated to prevent the sour soup from overflowing and causing blockage during pressure relief, thereby ensuring the normal pressure relief and avoiding safety accidents caused by blockage of materials during pressure relief, thereby significantly improving the safety of the device.

[0029] 3. The present invention can adaptively adjust the volume inside the quantitative tank by setting a quantitative plate that can be moved up and down and cooperating with the rotation of the screw, so that the device can adjust the maximum amount of fermented gas that can be temporarily stored according to different amounts of sour soup, so that the device can temporarily store the fermented gas under different sour soup storage amounts, and automatically release the pressure when the fermented gas exceeds a predetermined pressure, further improving the safety of the device during sour soup fermentation.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 8 As shown, in an embodiment of the present invention, a storage fermentation tank comprises a fermentation tank assembly 1, a frame 2 is fixedly installed on the right end of the outer side of the fermentation tank assembly 1, a gas quantitative assembly 8 is fixedly sleeved inside the frame 2, the top of the gas quantitative assembly 8 is connected to the right side of the fermentation tank assembly 1, a feed control assembly 3 is installed at a position near the bottom of the inner cavity of the fermentation tank assembly 1, a three-way valve 5 is fixedly connected to the position near the top on the right side of the gas quantitative assembly 8, a pressure relief flap valve 6 is fixedly connected to the top of the three-way valve 5, an auxiliary flap valve 7 is fixedly connected to the bottom of the three-way valve 5, and an air supply pipe 4 is fixedly connected to the bottom of the auxiliary flap valve 7, and the other end of the air supply pipe 4 passes through the outer side of the fermentation tank assembly 1 and is connected to the feed control assembly 3;

[0043] The fermentation tank assembly 1 includes a storage tank 101, and the bottom end of the inner cavity of the storage tank 101 is movably connected with a movable bottom plate 107. The left side of the storage tank 101 is fixedly connected with a material port 102 located above the movable bottom plate 107, and the inner side surface of the material port 102 is provided with a sealing groove 103. The right side of the storage tank 101 is provided with a through hole 105, one end of the gas pipe 4 passes through the through hole 105 and is connected to the feed control assembly 3, the bottom end of the feed control assembly 3 is connected to the middle part of the top of the movable bottom plate 107, and the right side of the storage tank 101 is provided with an exhaust hole 106 located above the gas quantitative assembly 8, and the other end of the exhaust hole 106 is connected to the gas quantitative assembly 8.

[0044] The pressure relief flap valve 6 and the auxiliary flap valve 7 are both in a normally closed state when the gas metering component 8 is not fully charged, and will only be opened when the gas content inside the gas metering component 8 exceeds the currently set gas storage capacity.

[0045] In the initial state, the feed control component 3 can completely seal the fermentation tank component 1. At this time, the device is in a sealed state. Before storing the sour soup, it is necessary to ensure that there is no sour soup remaining inside the feed port 102, and there is no sour soup remaining inside the storage tank 101. Ensure the cleanliness of the interior of the storage tank 101 and complete the preparation before storing the sour soup.

[0046] like Figure 2 and Figure 3 as well as Figure 4 As shown, a sealing top plate 104 located above the exhaust hole 106 is fixedly installed at the top of the inner cavity of the storage tank 101, and an inverted frustum-shaped groove is opened at the top of the movable bottom plate 107.

[0047] Among them, the space between the sealed top plate 104 and the movable bottom plate 107 is the maximum storage space of the storage tank 101. During storage, the maximum liquid level of the stored sour soup must not contact the sealed top plate 104. At the same time, the overall sour soup liquid level should be controlled at the bottom of the exhaust hole 106 to ensure that the sour soup will not overflow.

[0048] like Figure 2 and Figure 4 as well as Figure 5 and Figure 8 As shown, the feed control component 3 includes a fixed tube 301, the right end of the fixed tube 301 is connected to the right end of the inner side of the storage tank 101, the fixed tube 301 is internally movably sleeved with a movable plate 302, the right end of the movable plate 302 is fixedly connected to a return spring 303 located inside the fixed tube 301, the other end of the return spring 303 is connected to the right end of the inner cavity of the fixed tube 301, an air intake valve 304 is fixedly connected to the outer side of the fixed tube 301 near the left end, the other end of the air intake valve 304 is connected to the air delivery pipe 4, when the return spring 303 is in the initial state, the movable plate 302 is located on the right side of the input end of the air intake valve 304, the end of the movable plate 302 away from the return spring 303 is fixedly connected to a movable rod 305, the movable rod 305 passes through the left side of the fixed tube 301 and is fixedly connected to a sealing plug 306 located inside the material port 102, the sealing plug 306 is connected to the material The movable plate 302 is movably connected to the sealing groove 103, and the movable plate 302 is located at the leftmost side, that is, the reset spring 303 is in the initial state. The left side of the sealing plug 306 is movably connected with the sealing groove 103, and the outer side surface of the movable rod 305 is fixedly connected with the linkage frame 307. The first fixed seat 308 is fixedly installed on the right side of the bottom end of the linkage frame 307. The first fixed seat 308 is located directly below the fixed tube 301, and the end of the first fixed seat 308 away from the linkage frame 307 is movably connected to the connecting rod 3010 through a rotating shaft, and the end of the connecting rod 3010 away from the first fixed seat 308 is movably connected to the second fixed seat 309 through a rotating shaft. The bottom end of the second fixed seat 309 is connected to the middle part of the top of the movable bottom plate 107. When the sealing plug 306 is movably connected to the sealing groove 103, the movable bottom plate 107 is at the lowest point, that is, the bottom end of the movable bottom plate 107 contacts the bottom end of the inner cavity of the storage tank 101.

[0049] When the sealing plug 306 is completely displaced to the interior of the storage tank 101, a gap is generated between the sealing plug 306 and the storage tank 101, and the sour soup can then be input through the material port 102 and enter the interior of the storage tank 101 through the gap, thereby completing the injection of the sour soup. Alternatively, the sour soup can be directly pressurized to achieve the displacement of the sealing plug 306 to the interior of the storage tank 101 using the pressure of the sour soup, thereby completing the direct injection of the sour soup. After the injection is completed, the application of pressure to the sealing plug 306 can be stopped, and at this time, the reset spring 303 automatically resets to drive the movable plate 302 and the sealing plug 306 to automatically reset, until the sealing plug 306 is completely engaged with the sealing groove 103, thereby completing the self-sealing process.

[0050] When feeding and discharging the sour soup, it is necessary to apply pressure to the sealing plug 306 and make it enter the interior of the storage tank 101. When the sealing plug 306 is displaced to the right, the movable rod 305 and the linkage frame 307 can be displaced synchronously. At this time, the first fixed seat 308 is displaced to the right accordingly, and the connecting rod 3010 is driven to deflect. At this time, the second fixed seat 309 is subjected to a pulling force to the right, which can pull the movable bottom plate 107 to move upward, so that the top of the movable bottom plate 107 is close to the material port 102, which is convenient for the feeding and discharging process of the sour soup. When the device completes self-sealing and stops injecting material, the sealing plug 306 automatically resets to the left, which can drive the movable bottom plate 107 to move downward and restore to the initial state.

[0051] By utilizing the pressure during injection to achieve the displacement of the sealing plug 306, the device can only inject material under the action of pressure. At the same time, it can automatically achieve sealing when the injection is stopped, and the movable bottom plate 107 can automatically rise when the injection is ready to be discharged, thereby reducing the distance between the bottom end of the device and the feeding position, making it easier to feed and discharge the material. At the same time, the up and down displacement of the movable bottom plate 107 can also reduce the accumulation of sour soup at the bottom, avoid adhesion caused by aggregation, and improve the storage effect and feeding and discharging efficiency.

[0052] like Figure 2 and Figure 3 as well as Figure 6 and Figure 7 As shown, the gas quantitative assembly 8 includes a quantitative tank 801, the outer side surface of the quantitative tank 801 is fixedly connected to the frame 2, the top of the quantitative tank 801 is fixedly connected with a bend pipe 802, the other end of the bend pipe 802 is fixedly connected to the exhaust hole 106, and the right side of the quantitative tank 801 near the top is connected to the three-way valve 5.

[0053] Embodiment: When the internal fermentation gas of the storage tank 101 is too large and the fermentation gas temporarily stored in the quantitative tank 801 is full, as the pressure increases, the fermentation gas can enter the interior of the three-way valve 5 and exert pressure on the pressure relief flap valve 6 and the auxiliary flap valve 7, and the pressure flap valve is opened. At this time, part of the fermentation gas can be automatically discharged through the pressure relief flap valve 6, and at the same time, part of the fermentation gas can be input into the interior of the fixed pipe 301 through the auxiliary flap valve 7 and the gas supply pipe 4, and push the movable plate 302 to move to the right. At this time, the sealing plug 306 moves to the right, the material port 102 is opened, and the movable bottom plate 107 moves upward under the action of the connecting rod 3010, and the sour soup inside the storage tank 101 is discharged through the material port 102, reducing the sour soup inside the storage tank 101, until the fermentation gas returns to the normal pressure level, the fermentation gas inside the feed control component 3 is discharged, the feed control component 3 is automatically reset, and the discharge of the sour soup is automatically stopped.

[0054] By utilizing the gas generated during fermentation, that is, when the fermentation gas pressure is too high, the fermentation gas is introduced into the interior of the feed control component 3, and the feed port 102 is automatically opened through the action of the feed control component 3, so that the sour soup is automatically discharged, and the automatic pressure relief of the pressure relief flap valve 6 is cooperated, so that the sour soup will not overflow and cause blockage during the pressure relief, thereby ensuring the normal pressure relief and avoiding safety accidents caused by the blockage of materials during the pressure relief, thereby significantly improving the safety of the device.

[0055] like Figure 2 and Figure 6 as well as Figure 7 As shown, a quantitative plate 803 is provided inside the quantitative tank 801, and a card slot 804 is opened on both sides of the left and right sides of the inner cavity of the quantitative tank 801 near the bottom. The quantitative plate 803 is movably connected with the card slot 804 through a card block, and the quantitative plate 803 moves up and down relative to the card slot 804. A screw rod 806 is movably connected to the middle part of the bottom end of the quantitative plate 803, and a threaded sleeve 805 is fixedly installed in the middle part of the bottom end of the quantitative tank 801, and the outer side surface of the screw rod 806 is threadedly connected to the inner side surface of the threaded sleeve 805.

[0056] After the injection of the sour soup is completed, the gas metering component 8 can be adaptively adjusted according to the injection amount of the sour soup. When the injection amount of the sour soup is small, the quantitative plate 803 can be driven to move upward by rotating the screw 806 under the action of the threaded sleeve 805 and the guiding action of the slot 804, that is, the distance between the top of the inner cavity of the quantitative tank 801 and the top of the quantitative plate 803 is reduced. At this time, the amount of gas that can be stored in the quantitative tank 801 is reduced. Conversely, when the injection amount of the sour soup is large, the quantitative plate 803 can be moved downward to increase the distance between the top of the inner cavity and the top of the quantitative plate 803, thereby increasing the amount of gas that can be stored in the quantitative tank 801 and completing the adaptive adjustment process.

[0057] By setting a quantitative plate 803 that can be moved up and down and cooperating with the rotation of the screw 806, the volume inside the quantitative tank 801 can be adaptively adjusted, so that the device can adjust the maximum amount of fermented gas that can be temporarily stored according to different amounts of sour soup, so that the device can temporarily store the fermented gas under different sour soup storage conditions, and automatically release the pressure when the fermented gas exceeds a predetermined pressure, further improving the safety of the device during sour soup fermentation.

[0058] Working principle and usage process:

[0059] In the initial state, the feed control component 3 can completely seal the fermentation tank component 1. At this time, the device is in a sealed state. Before storing the sour soup, it is necessary to ensure that there is no sour soup left inside the feed port 102, and there is no sour soup left inside the storage tank 101. Ensure that the storage tank 101 is clean and complete the preparation before the sour soup storage.

[0060] The space between the sealed top plate 104 and the movable bottom plate 107 is the maximum storage space of the storage tank 101. During storage, the maximum liquid level of the stored sour soup must not contact the sealed top plate 104. At the same time, the overall liquid level of the sour soup should be controlled at the bottom of the exhaust hole 106 to ensure that the sour soup does not overflow.

[0061] When it is necessary to add sour soup to the interior of the storage tank 101, pressure can be applied to the sealing plug 306 to the right side, so that the sealing plug 306 is displaced to the right side, at which time the movable plate 302 can be driven to move to the right side and the return spring 303 can be compressed. At this time, the sealing plug 306 can be displaced relative to the material port 102. When the sealing plug 306 is completely displaced to the interior of the storage tank 101, a gap can be generated between the sealing plug 306 and the storage tank 101, and the sour soup can then be input through the material port 102 and enter the interior of the storage tank 101 through the gap, thereby completing the injection of the sour soup. Alternatively, the sour soup can be directly pressurized to utilize the pressure of the sour soup to achieve the displacement of the sealing plug 306 to the interior of the storage tank 101, thereby completing the direct injection process of the sour soup. After the injection is completed, the pressure on the sealing plug 306 can be stopped, and at this time, the return spring 303 automatically resets to drive the movable plate 302 and the sealing plug 306 to automatically reset, until the sealing plug 306 is completely engaged with the sealing groove 103, thereby completing the self-sealing process.

[0062] When feeding and discharging the sour soup, pressure needs to be applied to the sealing plug 306 and it needs to be made to enter the interior of the storage tank 101. When the sealing plug 306 is displaced to the right, the movable rod 305 and the linkage frame 307 can be displaced synchronously. At this time, the first fixed seat 308 is displaced to the right accordingly, and the connecting rod 3010 is driven to deflect. At this time, the second fixed seat 309 is subjected to a pulling force to the right, and the movable bottom plate 107 can be pulled to move upward, so that the top of the movable bottom plate 107 is close to the material port 102, which is convenient for the feeding and discharging process of the sour soup. When the device completes self-sealing and stops injecting materials, the sealing plug 306 automatically resets to the left, which can drive the movable bottom plate 107 to move downward and restore to the initial state.

[0063] After the injection of the sour soup is completed, the gas quantitative component 8 can be adaptively adjusted according to the injection amount of the sour soup. When the injection amount of the sour soup is small, the quantitative plate 803 can be driven to move upward by rotating the screw 806 under the action of the threaded sleeve 805 and the guiding action of the slot 804, that is, the distance between the top of the inner cavity of the quantitative tank 801 and the top of the quantitative plate 803 is reduced. At this time, the amount of gas that can be stored in the quantitative tank 801 is reduced. On the contrary, when the injection amount of the sour soup is large, the quantitative plate 803 can be moved downward to increase the distance between the top of the inner cavity and the top of the quantitative plate 803, thereby increasing the amount of gas that can be stored in the quantitative tank 801, and completing the adaptive adjustment process;

[0064] When the internal fermentation gas of the storage tank 101 is too large and the fermentation gas temporarily stored in the quantitative tank 801 is full, as the pressure increases, the fermentation gas can enter the interior of the three-way valve 5 and exert pressure on the pressure relief flap valve 6 and the auxiliary flap valve 7, and the pressure flap valve is opened. At this time, part of the fermentation gas can be automatically discharged through the pressure relief flap valve 6, and at the same time, part of the fermentation gas can be input into the interior of the fixed pipe 301 through the auxiliary flap valve 7 and the gas supply pipe 4, and push the movable plate 302 to move to the right. At this time, the sealing plug 306 moves to the right, the material port 102 is opened, and the movable bottom plate 107 moves upward under the action of the connecting rod 3010, and the sour soup inside the storage tank 101 is discharged through the material port 102, reducing the sour soup inside the storage tank 101, until the fermentation gas returns to the normal pressure level, the fermentation gas inside the feed control component 3 is discharged, the feed control component 3 automatically resets, and the discharge of the sour soup is automatically stopped.
