Description

Technical Field

[0001] This invention relates to an automated wine conveying system, and more particularly to an automated wine conveying system for wine cellars, belonging to the field of design and manufacturing technology of equipment for the production, storage and transfer of alcoholic beverages. Background Technology

[0002] Natural or artificial cave storage typically consists of 1-3 main tunnels and several branch tunnels, and can be used for storing high-end base spirits for baijiu. However, due to space limitations, earthenware jars are usually placed in a tunnel-like arrangement, with each jar having a volume of approximately 1 cubic meter. 3 A single wine storage cave can hold thousands or even tens of thousands of ceramic jars, which is a typical wine storage scenario with many containers but small individual container volume.

[0003] The current wine transfer operation in the ceramic jar storage cellar is manual: both loading and unloading wine from the jars require manual opening of the lid, insertion of a stainless steel transfer hose into the jar, and activation of the pump. Especially when unloading, the hose must be extended to the bottom of the jar. Furthermore, during loading and unloading, employees must continuously exert force to prevent significant displacement of the hose, thus avoiding damage to the jar under the influence of the fluid. After completing the transfer of wine from one jar, the hose and pump are manually moved to the next. This process is not only inefficient and physically demanding for operators, but also creates a poor working environment and is highly susceptible to accidents such as jar breakage. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automated wine conveying system for wine cellars that can effectively reduce the labor intensity of operators and improve the working environment.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: an automated wine conveying system for a wine cellar, including multiple ceramic jars arranged sequentially along the extension direction of the wine cellar. The automated wine conveying system also includes a control center, an inlet and outlet wine conveying pipeline system, a pumping drive component, and a transfer and temporary storage metering component. The transfer and temporary storage metering component is connected to each ceramic jar through the inlet and outlet wine conveying pipeline system. The pumping drive component is connected in series between the inlet and outlet wine conveying pipeline system and the transfer and temporary storage metering component. The wine is transferred between the ceramic jars and the transfer and temporary storage metering component through the inlet and outlet wine conveying pipeline system and the pumping drive component in cooperation with the control center.

[0006] Furthermore, the automated wine delivery system also includes a monitoring and control component, which is located in the intermediate storage and metering component. The pump drive component is turned on or off in coordination with the monitoring and control component and the control center according to the liquid level of the wine in the intermediate storage and metering component.

[0007] The preferred embodiment of the above scheme is that the monitoring and control component includes multiple remote pressure transmitters, and the signal output terminals of each remote pressure transmitter arranged in the intermediate temporary metering component are connected to the control center.

[0008] Furthermore, the control center includes a computer with an editable module, and at least the control terminals of the pump drive component and the monitoring and control component are connected to the editable module.

[0009] The preferred embodiment of the above scheme is that the inlet and outlet wine conveying pipeline system includes at least an inlet wine conveying main pipe, an outlet wine conveying main pipe, and a wine conveying connecting pipe. The inlet wine conveying main pipe and the outlet wine conveying main pipe are both arranged at the top of the wine storage cave at a 1% slope along the extension direction of the wine storage cave. The horizontal elevation of the wine inlet end of the inlet wine conveying main pipe and the wine outlet end of the outlet wine conveying main pipe are both higher than the horizontal elevation of the wine outlet end of the inlet wine conveying main pipe and the outlet wine conveying main pipe. Both ends of the pump drive component are connected to the transfer temporary storage metering component and the inlet wine conveying main pipe and / or the outlet wine conveying main pipe respectively through the wine conveying connecting pipe. Each ceramic jar is connected to the inlet wine conveying main pipe at intervals through the wine conveying connecting pipe. The grouped ceramic jars are connected to the outlet wine conveying main pipe in sections through the wine conveying connecting pipe and the pump drive component in cooperation with the inlet wine conveying main pipe.

[0010] Furthermore, the transit and temporary storage metering assembly includes at least an inlet high-level metering tank, a vertical transit tank, and a horizontal transit tank. The inlet high-level metering tank is installed at an elevation no lower than the entrance of the wine storage cave where the wine inlet conveying main pipe is located. The vertical transit tank is connected to the inlet high-level metering tank via a wine conveying connection pipe in cooperation with the pump drive assembly. The wine inlet of the wine conveying main pipe is connected to the output of the inlet high-level metering tank. The horizontal transit tank is connected to the wine output of the outlet conveying main pipe via a wine conveying connection pipe in cooperation with the pump drive assembly. At least one remote pressure transmitter is installed in each of the inlet high-level metering tank, the vertical transit tank, and the horizontal transit tank.

[0011] The preferred embodiment of the above scheme is that the transit and temporary storage metering component further includes a relay high-level metering tank, an inlet relay buffer tank, and an outlet relay buffer tank. Multiple relay high-level metering tanks, inlet relay buffer tanks, and outlet relay buffer tanks are used. The inlet and outlet conveying mains are arranged in sections along the length of the wine cellar at corresponding positions on the top of the wine cellar, according to their installation elevations. At the wine inlet end of each section of the inlet conveying main, a relay high-level metering tank with an installation elevation higher than that of the inlet end is installed via a connecting pipe. Each relay high-level metering tank is connected to a corresponding pump. The drive assembly and wine delivery connection pipe are connected to an intermediate wine delivery buffer tank at the output end of the adjacent upstream wine delivery main pipe. At the wine output end of each wine delivery main pipe, an intermediate wine delivery buffer tank with an installation elevation lower than that of the wine output end is arranged through a wine delivery connection pipe. Each intermediate wine delivery buffer tank is connected to the wine input end of the adjacent downstream wine delivery main pipe through a corresponding pump drive assembly and wine delivery connection pipe. At least one remote pressure transmitter is installed in each intermediate high-level metering tank, each intermediate wine delivery buffer tank, and each intermediate wine delivery buffer tank.

[0012] Furthermore, the pumping drive assembly includes multiple explosion-proof centrifugal wine pumps and multiple pneumatic diaphragm pumps. One explosion-proof centrifugal wine pump is connected in series at both the wine inlet and outlet ends of the vertical transfer tank, and another explosion-proof centrifugal wine pump is connected in series at the wine outlet end of the horizontal transfer tank. Each wine inlet relay buffer tank is connected to the adjacent relay high-level metering tank via a pneumatic diaphragm pump, and each wine outlet relay buffer tank is connected to the wine inlet end of the adjacent next wine outlet conveying main pipe via a pneumatic diaphragm pump. The wine inlet conveying main pipe sections with grouped ceramic jars are connected to the corresponding wine outlet conveying main pipe sections via wine conveying connecting pipes, and the control terminals of each explosion-proof centrifugal wine pump and each pneumatic diaphragm pump are connected to an editable module.

[0013] The preferred embodiment of the above scheme is that the automated wine conveying system further includes a mass flow meter and a vortex flow meter, and the inlet and outlet wine conveying pipeline system also includes a check valve and a solenoid valve. A check valve and a mass flow meter are connected in series between the wine inlet end of the vertical transfer tank and the explosion-proof centrifugal wine pump. A check valve is connected in series between the explosion-proof centrifugal wine pump at the wine outlet end of the vertical transfer tank and the inlet high-level metering tank. A mass flow meter and a check valve are connected in series at the wine outlet end of the explosion-proof centrifugal wine pump at the wine outlet end of the horizontal transfer tank. A vortex flow meter and a check valve are connected in series at the wine outlet end of the horizontal transfer tank. A solenoid valve is connected in series at both ends of each pneumatic diaphragm pump. A solenoid valve is connected in series on the wine conveying connection pipe connecting each ceramic jar to the wine inlet conveying main pipe. The control terminals of the mass flow meter, vortex flow meter, check valve, and solenoid valve are all connected to the editable module.

[0014] Furthermore, the wine transfer connection pipe includes a wine transfer hose and a transfer wine transfer rigid pipe. Each explosion-proof centrifugal wine pump is connected in series to the vertical and horizontal transfer tanks through the transfer wine transfer rigid pipe. Each pneumatic diaphragm pump is connected to the wine inlet and wine outlet main pipes through the wine transfer hose.

[0015] The beneficial effects of this invention are as follows: The technical solution provided in this application is based on multiple earthenware jars arranged sequentially along the extension direction of the existing wine cellar. By adding a control center, an inlet and outlet wine delivery pipeline system, a pumping drive component, and a transfer and temporary storage metering component, the automated wine delivery system of this application is constructed. Then, the transfer and temporary storage metering component is connected to each earthenware jar through the inlet and outlet wine delivery pipeline system, and the pumping drive component is connected in series between the inlet and outlet wine delivery pipeline system and the transfer and temporary storage metering component. During the wine transfer, the wine is transferred between the earthenware jars and the transfer and temporary storage metering component through the inlet and outlet wine delivery pipeline system and the pumping drive component in cooperation with the control center. This changes the existing technology where both inlet and outlet of wine, especially outlet wine, require operators to hold the inlet pipe deep into the bottom of the earthenware jar for an extended period. Instead, the wine is automatically transferred between the temporary storage tank and the earthenware jar via the inlet and outlet delivery pipeline system, pump drive components, and control center. This not only effectively reduces the labor intensity of operators and improves the working environment, but also significantly improves transfer efficiency and greatly reduces the probability of safety accidents such as jar breakage.

[0018] like Figure 1The invention illustrates an automated wine transfer system for a wine cellar, which effectively reduces the labor intensity of operators and improves the working environment. The automated wine transfer system includes multiple ceramic jars 1 arranged sequentially along the extension direction of the wine cellar. It also includes a control center 2, inlet and outlet wine transfer pipelines, a pumping drive assembly, and a transfer and temporary storage metering assembly. The transfer and temporary storage metering assembly is connected to each ceramic jar 1 via the inlet and outlet wine transfer pipelines. The pumping drive assembly is connected in series between the inlet and outlet wine transfer pipelines and the transfer and temporary storage metering assembly. Wine is transferred between the ceramic jars 1 and the transfer and temporary storage metering assembly through the inlet and outlet wine transfer pipelines and the pumping drive assembly, with the cooperation of the control center 2. The technical solution provided in this application is based on multiple ceramic jars arranged sequentially along the extension direction of an existing wine cellar. By adding a control center, inlet / outlet wine delivery pipelines, a pump drive assembly, and a transfer / temporary storage metering assembly, an automated wine delivery system is constructed. The transfer / temporary storage metering assembly is then connected to each ceramic jar via the inlet / outlet wine delivery pipelines, and the pump drive assembly is connected in series between the inlet / outlet wine delivery pipelines and the transfer / temporary storage metering assembly. During wine transfer, the wine is transferred between the ceramic jars and the transfer / temporary storage metering assembly with the cooperation of the control center through the inlet / outlet wine delivery pipelines and the pump drive assembly. This changes the existing technology where, for both inlet and outlet wine, especially outlet wine, operators must hold the inlet pipe to the bottom of the ceramic jar for an extended period. Instead, the transfer of wine between the temporary storage tank and the ceramic jars is automated through the inlet / outlet wine delivery pipelines, the pump drive assembly, and the control center. This not only effectively reduces the labor intensity of operators and improves the working environment but also significantly improves transfer efficiency and greatly reduces the probability of safety accidents such as jar breakage.

[0019] Accordingly, to achieve automated transfer of the liquor as much as possible, the automated liquor transfer system described in this application also includes a monitoring and control component. This component is located within the intermediate storage and metering component. The pump drive component is activated or deactivated based on the liquor level in the intermediate storage and metering component, in coordination with the monitoring and control component and the control center 2. Preferably, the monitoring and control component includes multiple remote pressure transmitters 3, with the signal output terminals of each remote pressure transmitter 3 located in the intermediate storage and metering component connected to the control center 2. The corresponding control center 2 preferably includes a computer with an editable module, and at least the control terminals of the pump drive component and the monitoring and control component are connected to the editable module.

[0020] Furthermore, as the main structural improvement of this application, in order to adapt to the structure of the wine cellar itself, and at the same time to simplify the structure of each component as much as possible, facilitate manufacturing and installation, and reduce construction costs and maintenance costs during use, the wine inlet and outlet conveying pipeline system of this application includes at least an inlet conveying main pipe 4, an outlet conveying main pipe 5, and a wine conveying connecting pipe. The inlet conveying main pipe 4 and the outlet conveying main pipe 5 are both arranged at a 1% slope along the extension direction of the wine cellar at the top of the cellar. The horizontal elevation of the wine inlet end of the wine conveying main pipe 5 is higher than the horizontal elevation of the wine outlet end of the wine conveying main pipe 4 and the wine outlet end of the wine conveying main pipe 5. Both ends of the pump drive assembly are connected to the transfer and temporary storage metering assembly and the wine conveying main pipe 4 and / or the wine outlet conveying main pipe 5 respectively through wine conveying connection pipes. Each ceramic jar 1 is connected to the wine conveying main pipe 4 at intervals through wine conveying connection pipes. Each ceramic jar 1 arranged in groups is connected to the wine outlet conveying main pipe 5 in sections through wine conveying connection pipes and pump drive assembly in cooperation with the wine conveying main pipe 4. The intermediate storage and metering assembly includes at least an inlet high-level metering tank 6, a vertical transfer tank 7, and a horizontal transfer tank 8. The inlet high-level metering tank 6 is installed at an elevation no lower than the entrance of the wine storage cave where the wine inlet conveying main pipe 4 is located. The vertical transfer tank 7 is connected to the input end of the inlet high-level metering tank 6 via a wine conveying connection pipe in cooperation with the pump drive assembly. The wine inlet end of the wine inlet conveying main pipe 4 is connected to the output end of the inlet high-level metering tank 6. The horizontal transfer tank 8 is connected to the wine output end of the outlet wine conveying main pipe 5 via a wine conveying connection pipe in cooperation with the pump drive assembly. At least one remote pressure transmitter 3 is arranged in each of the inlet high-level metering tank 6, the vertical transfer tank 7, and the horizontal transfer tank 8. The pumping drive assembly includes multiple explosion-proof centrifugal wine pumps 12 and multiple pneumatic diaphragm pumps 13. One explosion-proof centrifugal wine pump 12 is connected in series at both the wine inlet and outlet of the vertical transfer tank 7, and one explosion-proof centrifugal wine pump 12 is connected in series at the wine outlet of the horizontal transfer tank 8. Each wine inlet relay buffer tank 10 is connected to the adjacent relay high-level metering tank 9 via a pneumatic diaphragm pump 13. Each wine outlet relay buffer tank 11 is connected to the wine inlet of the adjacent next wine outlet conveying main pipe 5 via a pneumatic diaphragm pump 13. The wine inlet conveying main pipes of the grouped ceramic jars 1 are connected to the corresponding wine outlet conveying main pipes via wine conveying connecting pipes. The control terminals of each explosion-proof centrifugal wine pump 12 and each pneumatic diaphragm pump 13 are connected to an editable module.Considering the depth of the wine cellar, the temporary storage and metering assembly described in this application also includes a relay high-level metering tank 9, an inlet relay buffer tank 10, and an outlet relay buffer tank 11. Multiple relay high-level metering tanks 9, inlet relay buffer tanks 10, and outlet relay buffer tanks 11 are present. The inlet conveying main pipe 4 and outlet conveying main pipe 5 are arranged in sections along the length of the wine cellar at corresponding positions on the top of the wine cellar, according to their installation elevations. At the wine inlet end of each section of the inlet conveying main pipe 4, a relay high-level metering tank 9 with an installation elevation higher than that of the wine inlet end is installed via a connecting pipe. Each relay high-level metering tank 9 is connected to a... The corresponding pump drive assembly and wine delivery connection pipe are connected to an intermediate wine delivery buffer tank 10 connected to the output end of the adjacent upper section of the wine delivery main pipe 4; at the wine output end of each section of the wine delivery main pipe 5, an intermediate wine delivery buffer tank 11 with an installation elevation lower than that of the wine output end is arranged through a wine delivery connection pipe. Each intermediate wine delivery buffer tank 11 is connected to the wine input end of the adjacent lower section of the wine delivery main pipe 5 through a corresponding pump drive assembly and wine delivery connection pipe. At least one remote pressure transmitter 3 is installed in each intermediate high-level metering tank 9, each intermediate wine delivery buffer tank 10 and each intermediate wine delivery buffer tank 11.

[0021] Meanwhile, to facilitate metering and provide action parameters to the control center, the automated wine conveying system described in this application also includes a mass flow meter 14 and a vortex flow meter 15. The inlet and outlet wine conveying pipeline system also includes a check valve 16 and a solenoid valve 17. A check valve 16 and a mass flow meter 14 are connected in series between the wine inlet end of the vertical transfer tank 7 and the explosion-proof centrifugal wine pump 12. A check valve 16 is connected in series between the explosion-proof centrifugal wine pump 12 at the wine outlet end of the vertical transfer tank and the inlet high-level metering tank 6. A mass flow meter 14 and a check valve 16 are connected in series at the liquid output end of the explosion-proof centrifugal wine pump 12. A vortex flow meter 15 and a check valve 16 are connected in series at the liquid output end of the horizontal transfer tank 6. A solenoid valve 17 is connected in series at both ends of each pneumatic diaphragm pump 13. A solenoid valve 17 is connected in series on the wine delivery connection pipe connecting each ceramic jar 1 to the wine delivery main pipe 4. The control terminals of the mass flow meter 14, vortex flow meter 15, check valve 16, and solenoid valve 17 are all connected to the editable module. In addition, considering the connection requirements, the wine delivery connection pipe mentioned in the application includes a wine delivery hose 18 and a transition wine delivery rigid pipe 19. Each explosion-proof centrifugal wine pump 12 is connected in series to the vertical transfer tank 7 and the horizontal transfer tank 8 through the transition wine delivery rigid pipe 19. Each pneumatic diaphragm pump 13 is connected to the wine delivery main pipe 4 and the wine delivery main pipe 5 through the wine delivery hose 18.

[0022] In summary, the technical solution described above in this application for transferring wine also has the following advantages:

[0023] 1) Significant cost advantages, mainly reflected in the following three aspects:

[0024] ①If a valve array system is adopted, based on the calculation of a cave storage for 5,000 pottery jars, it is estimated that more than 5,000 seat valves will be used for valve array design, the cost of valve array alone will exceed 70 million yuan, and the area occupied is huge.

[0025] ② The unique wine dispensing pipeline design only requires one pneumatic diaphragm pump interface to be installed in each group of ceramic jars (each group contains approximately 20-40 ceramic jars), eliminating the need for a separate wine dispensing interface on each ceramic jar. Based on a storage facility holding 5000 ceramic jars, this is expected to reduce the number of tees, solenoid valves, and other pipes and equipment by 4800, resulting in cost reductions of nearly 11 million yuan.

[0026] ③ By adopting a high-level metering tank and vortex flow meter design, it is no longer necessary to consider the liquid level monitoring of individual ceramic jars. That is, it is not necessary to install an independent remote liquid level transmission device on each ceramic jar. Based on the calculation of a cavern storing 5,000 ceramic jars, this alone reduces costs by nearly 17.5 million yuan.

[0027] 2) Solve the problem of inaccurate measurement in small-batch, multi-batch wine delivery operations.

[0028] Currently available liquid flow meters, such as the Coriolis mass flow meter, operate ideally under conditions of large volume, stable flow rate, no gas-liquid miscibility, and minimal environmental vibration. However, the conditions faced by earthenware jar wine storage facilities are that each jar has a capacity of only 1 ton and there is gas-liquid miscibility, which differs significantly from the ideal conditions. Therefore, using various electronic flow meters in the wine-filling process of earthenware jar wine storage facilities is unreliable. This application adopts the form of a high-level metering tank, which only requires calibrating the weight corresponding to each liquid level before the first use to achieve accurate metering.

[0029] 3) Significantly reduces labor intensity, decreases the number of operators, and enables automated wine handling operations.

[0030] The existing earthenware jar wine storage facility operated manually: adding or removing wine from the jars required manual opening of the lid, insertion of a stainless steel wine transfer hose into the jar, and activation of the pump; especially when removing wine, the hose had to be extended to the bottom of the jar. Furthermore, during both loading and unloading, employees had to continuously exert force to prevent significant displacement of the hose, thus avoiding damage to the jar under the influence of the fluid. After completing the transfer of wine from one jar, the hose and pump were manually moved to the next. Each operation required four people. This application requires only operation in the control room, with only 1-2 people needed.

[0031] 4) Solves the problem of excessive vibration in the pipelines inside the jars when pumping wine in, and saves energy. The original wine feeding operation relied on centrifugal pumps, which caused large vibrations at the end of the pipelines.

[0032] During the wine-feeding process, especially after the main wine-feeding pipeline is laid at a slope, simply opening the solenoid valve corresponding to the target ceramic jar allows the wine to flow slowly by gravity. This not only solves the pipeline vibration problem but also saves energy.

[0033] 5) The system can be set up in parallel with multiple "high-level metering tanks". When "high-level metering tank No. 1" is replenishing wine, it can be switched to "high-level metering tank No. 2" to feed wine into the "earthenware jar", thereby improving the efficiency of operation.

[0034] 6) Group setting of "ceramic jars" solves the problem that the coverage area of ​​pneumatic diaphragm pumps cannot be too large.

[0035] 7) Pneumatic diaphragm pumps can adapt to dry running conditions, so there is no need to worry about centrifugal pumps or other pumps being damaged during dry running.

[0036] 8) The problem of gravitational potential energy failure in sloped wine transport pipelines in deep and long tunnels is solved by using "inlet relay buffer tank", "relay high-level metering tank" and "outlet relay buffer tank".

[0037] 9) The use of power supplies and equipment with voltages above 24V is completely prohibited inside the cave to ensure the safety of the wine source inside the cave.

[0038] The technical solution of this application will be further described below through specific embodiments:

[0039] Automated earthenware jar wine storage is the future direction, as existing manual methods are inefficient and labor-intensive. Using a valve array system similar to that of large tank-type wine cellars to automate the wine transfer in earthenware jar storage caverns would face enormous construction costs (a storage cavern with 5,000 earthenware jars would require a valve array system consisting of at least 5,000 valve seats, the cost of which is incalculable), and the limited space would make it impractical to install a large number of automated devices.

[0040] This application significantly reduces costs while meeting the requirements for automated wine conveying in wine cellars.

[0041] 1) The system consists of a "transfer tank", "high-level metering tank", "centrifugal pump", "pneumatic diaphragm pump", "ceramic jar", "solenoid valve" (24V voltage), "pressure transmitter", "mass flow meter", "vortex flow meter", "wine conveying pipeline", "wine inlet and outlet pipes inside the jar", and "control computer and software".

[0042] 2) The "vertical transfer tank" has a volume slightly larger than that of the tanker truck, which can effectively accommodate the transport volume of a single tanker truck; it is used to temporarily store the liquid in the tank when the tanker truck is transporting the liquid to the underground storage facility (hereinafter referred to as "liquor loading operation"). The lower part of the tank is equipped with a "pressure transmitter".

[0043] 3) The volume of the "horizontal transfer tank" is slightly smaller than that of the tanker truck, and its full volume of liquid can be transferred by a single tanker truck in one trip; it is used for transferring wine from the underground storage to the tanker truck (hereinafter referred to as "wine discharge operation"). To minimize the impact of the liquid level in the "horizontal transfer tank" on the flow rate of the wine discharge pipeline inside the underground storage, the "horizontal transfer tank" should be as flat as possible, with its highest internal height preferably at least 1 meter lower than the elevation of the "main wine discharge pipeline" at the cave entrance (i.e., "elevation 3" is more than 1 meter higher than "elevation 4"). A "pressure transmitter" is installed at the bottom of the tank.

[0044] 4) The volume of the "high-level metering tank" is slightly smaller than that of a single "earthenware jar," and the liquid inside the tank can be completely contained by a single "earthenware jar." To accelerate the flow rate of the liquor, its lowest internal height should be at least 1 meter higher than the elevation of the "main liquor inlet pipe" at the opening (i.e., "elevation 1" is at least 1 meter higher than "elevation 2"). A "pressure transmitter" is installed at the bottom of the tank.

[0045] 5) The slope of the "main pipe for wine delivery" inside the cave should be formed according to the actual situation, with the highest elevation at the cave entrance and the lowest at the end inside the cave, and the slope should be at least 1%.

[0046] 6) The lowest point of the "inlet and outlet tube" inside the jar should be slightly higher than the bottom of the jar, and the gap between the lowest point and the bottom of the jar should be 1-2 cm.

[0047] 7) The slope of the "main pipe for dispensing wine" inside the cave should be formed according to the actual situation, with the lowest elevation at the cave entrance and the highest elevation at the end inside the cave, and the slope should be at least 1%.

[0048] 8) Based on the suction power and operating distance of the "pneumatic diaphragm pump", set up "ceramic jars" in groups, with multiple ceramic jars sharing one "pneumatic pump inlet". Set up a "pneumatic pump outlet" at the corresponding position on the "main outlet pipe".

[0049] 9) The pressure transmitter on the vertical transfer tank is used to monitor the liquid level in the tank in real time and is linked to centrifugal pumps No. 1 and No. 2. The signal is connected to the control computer. Two parameters are set: "Liquid Level 1" (near the bottom of the tank) and "Liquid Level 2" (located at the top of the tank, the specific value is determined after calculation). When the system is running, if the pressure transmitter reading is less than or equal to "Liquid Level 1", centrifugal pump No. 2 cannot be started to avoid it running dry; if the pressure transmitter reading is "Liquid Level 2", the control system automatically shuts down centrifugal pump No. 1 to prevent accidental tank overflow.

[0050] 10) The pressure transmitter on the "high-level metering tank" is used to monitor the liquid level in the "high-level metering tank" in real time and is linked with the "No. 2 centrifugal pump". The signal is connected to the "control computer". Two parameters are set: "liquid level 1" (near the bottom of the tank) and "liquid level 2" (located at the top of the tank, the specific value is determined after calculation). When the system is running, when the reading of the "pressure transmitter" is less than or equal to "liquid level 1", the control system automatically starts the "No. 2 centrifugal pump" to pump the wine in the "vertical transfer tank" to the "high-level metering tank"; when the reading of the "pressure transmitter" is "liquid level 2", the control system automatically shuts down the "No. 2 centrifugal pump".

[0051] 11) After selecting a specific "earthenware jar" number in the "Control System," the system automatically opens the corresponding "solenoid valve" and automatically opens or closes the "solenoid valve" on the "Main Wine Inlet Pipe." The wine flows by gravity from the "High-Level Metering Tank" into the corresponding earthenware jar. When the reading of the "Pressure Transmitter" in the "High-Level Metering Tank" drops to "Liquid Level 1," all "solenoid valves" close. This completes the wine inlet operation for a single "earthenware jar."

[0052] 12) When dispensing wine, after selecting the specific "earthenware jar" number in the "control system," the system automatically activates the corresponding "solenoid valve" and automatically opens or closes the "solenoid valves" on the "inlet main pipe" and "outlet main pipe." The "control system" starts the "pneumatic diaphragm pump" to transport the wine from the "earthenware jar" to the "horizontal transfer tank." When the "vortex flow meter" reading remains unchanged for a certain period of time (ideally 3-5 minutes), the "control system" automatically shuts off the "pneumatic diaphragm pump" and the corresponding "solenoid valve." This completes the dispensing operation for a single "earthenware jar."

[0053] 13) The pressure transmitter on the horizontal transfer tank is used to monitor the liquid level in the tank in real time and is linked with the centrifugal pump No. 3 and the pneumatic diaphragm pump. The signal is connected to the control computer. Two parameters are set: "Liquid Level 1" (near the bottom of the tank) and "Liquid Level 2" (located at the top of the tank, the specific value is determined after calculation). When the system is running, if the pressure transmitter reading is ≤ "Liquid Level 1", the centrifugal pump No. 3 cannot be started to avoid it running dry; if the pressure transmitter reading is "Liquid Level 2", the control system automatically shuts down the pneumatic diaphragm pump to prevent accidental tank overflow.

[0054] (14) To improve efficiency, multiple "high-level metering tanks" can be set up in parallel. When "high-level metering tank No. 1" is replenishing wine, the process can be switched to "high-level metering tank No. 2" to feed wine into the "earthenware jar". (Note: "high-level metering tanks" connected in parallel cannot feed wine into the "earthenware jar" at the same time.)

[0055] 15) Due to the depth of the wine storage cave, and the height of the cave ceiling being generally 3-4 meters, the pipeline is installed with a 1% slope. When the cave length reaches 200-300 meters, the pipeline elevation is basically level with the mouth of the earthenware jar. Further depth would prevent the use of gravitational potential energy for wine intake. Therefore, before the pipeline elevation is roughly level with the mouth of the earthenware jar, a "relay buffer tank" and a "relay high-level metering tank" are installed to restore the gravitational potential energy difference.

[0056] ① The effective volume of the "wine inlet relay buffer tank" should ideally be twice the effective volume of the "ceramic jar". A "pressure transmitter" is used to monitor the liquid level in the "wine inlet relay buffer tank" in real time and is linked to the "X-type pneumatic diaphragm pump". The signal is connected to the "control computer". Two parameters are set: "Liquid Level 1" (near the bottom of the tank) and "Liquid Level 2" (located at the top of the tank, the specific value is determined after calculation). When the system is running, if the "pressure transmitter" reading is "Liquid Level 2", the "J1 solenoid valve" will be closed to prevent overflow; if the "pressure transmitter" reading is ≤ "Liquid Level 1", the "J1 solenoid valve" will be restarted.

[0057] ② The "intermediate high-level metering tank" has the same volume as the "high-level metering tank." To accelerate the flow rate of the liquid, it should be installed as close as possible to the inner wall of the tunnel top. The difference between "elevation 4" and "elevation 5" should ideally be greater than 1 meter. A "pressure transmitter" is provided to monitor the liquid level in the "intermediate high-level metering tank" in real time and is linked to the "X-type pneumatic diaphragm pump," with the signal connected to the "control computer." Two parameters are set: "liquid level 1" (near the bottom of the tank) and "liquid level 2" (located at the top of the tank, the specific value is determined after calculation). When the system is running, if the "pressure transmitter" reading is "liquid level 2," the "X-type pneumatic diaphragm pump" will be shut down to prevent overflow; if the "pressure transmitter" reading is ≤ "liquid level 1," the "X-type pneumatic diaphragm pump" will be restarted.

[0058] 16) When discharging wine, in order to restore the gravitational potential energy difference of the discharging pipe, a "wine discharging intermediate buffer tank" is set up, and a "high-level pipe" is set up. The "elevation 6" of the "high-level pipe" should be as close as possible to the inner wall of the tunnel top.

[0059] The effective volume of the "wine dispensing relay buffer tank" should ideally be twice the effective volume of the "ceramic jar." It is equipped with a "pressure transmitter" for real-time monitoring of the liquid level within the tank, and is linked to the "Z-type pneumatic diaphragm pump," with the signal connected to the "control computer." Two parameters are set: "Liquid Level 1" (near the bottom of the tank) and "Liquid Level 2" (located at the top of the tank, the specific value determined after calculation). During system operation, when the "pressure transmitter" reading is "Liquid Level 2," the "pneumatic diaphragm pump" currently supplying wine to the "wine dispensing relay buffer tank" is shut down to prevent overflow. Simultaneously, the "Z-type pneumatic diaphragm pump" is activated to transfer the wine from the tank to the "high-level pipeline." When the "pressure transmitter" reading is less than or equal to "Liquid Level 1," the "pneumatic diaphragm pump" supplying wine to the "wine dispensing relay buffer tank" is restarted.

[0060] Example 1

[0061] With a full-load effective volume of 33m³, the wine tanker truck 3 The effective volume of a single ceramic jar is 1m³. 3 For example.

[0062] Based on the effective volume of the wine tanker and earthenware jars, the effective volumes of other containers are set as follows: ① Vertical transfer tank: effective volume 35m³ 3 The pressure transmitter shows a level reading of 0.0 meters for level 1 and 5.0 meters for level 2 (at 5 meters, the volume is exactly 34 m³). 3 This value needs to be verified and determined during commissioning. As an overflow protection measure, when the liquid level reaches 5 meters, centrifugal pump No. 1 will be immediately shut down. ② The effective volume of the high-level metering tank is 1.2 m³. 3 The pressure transmitter shows a liquid level value of 0.0 meters for level 1 and 1.0 meters for level 2 (when the liquid level is 1 meter, the volume is exactly 1 cubic meter). 3 This value needs to be verified and determined during commissioning. It serves as overflow protection and metering positioning. When the liquid level reaches 1 meter, centrifugal pump No. 2 will be immediately shut down. ③ The effective volume of the horizontal transfer tank is 32m³. 3 The pressure transmitter level 1 is 0.0 meters (this value serves as a protection against dry running of centrifugal pump No. 3; when the level reaches 0.0 meters, centrifugal pump No. 3 will be immediately shut down to prevent dry running), and the level 2 is 2.0 meters (at 2 meters, the volume is exactly 31m³). 3 This value needs to be verified and determined during commissioning. As an overflow protection measure, when the liquid level reaches 2 meters, the pneumatic diaphragm pump will be shut down immediately.

[0063] 1) Wine delivery operation

[0064] ① Upon arrival of the tanker truck, a manual connection is made using a hose to link the truck's outlet to the inlet of centrifugal pump No. 1. The control room checks and confirms that the liquid level in the vertical transfer tank is below level 1. Once confirmed, the control room starts centrifugal pump No. 1 to transfer all the liquid from the tanker truck into the vertical transfer tank. Mass flow meter measurement is then performed.

[0065] ② The control room checks and confirms that the liquid level in the high-level metering tank is below level 2. After confirmation, the control room starts centrifugal pump No. 2 for the first time to transport the liquor from the vertical transfer tank to the high-level metering tank until the liquid level in the high-level metering tank reaches level 2, at which point centrifugal pump No. 2 is automatically shut down. Subsequently, the starting and stopping of centrifugal pump No. 2 are all controlled by the pressure transmitter in the high-level metering tank.

[0066] ③ The control room determines to add wine to jar No. 2. After entering the jar No. 2 number, the J1 and T2 solenoid valves automatically open (other solenoid valves remain closed). Wine flows by gravity from the high-level metering tank into jar No. 2. When the liquid level in the high-level metering tank drops to level 1, the system automatically closes the J1 and T2 solenoid valves after a 5-minute delay (ensuring all remaining wine in the pipeline has flowed out by gravity). If it is necessary to add wine to other jars...

[0067] ④ When the liquid level in the high-level metering tank drops to level 1, if there is no human intervention, the No. 2 pneumatic diaphragm pump will automatically start under the linkage control of the control system until the liquid level in the high-level metering tank reaches level 2.

[0068] ⑤ After the high-level metering tank is filled with wine, continue to add wine to other earthenware jars. If two high-level metering tanks are set up in parallel, the second high-level metering tank can be switched to add wine to the earthenware jars while the first high-level metering tank is being filled, thus saving time.

[0069] 2) Wine dispensing operation

[0070] ① After the tanker truck arrives, a manual hose is used to connect the tanker truck's outlet to the outlet of centrifugal pump No. 3. The control room checks and confirms that the liquid level in the horizontal transfer tank is below level 2. After confirmation, the control room enters the number of ceramic jar No. 3 and opens solenoid valves T3, QJ1, and QC1 (other solenoid valves are closed) to transfer the liquid in ceramic jar No. 3 to the horizontal transfer tank.

[0071] ② When the vortex flow meter detects no change in value within 5 minutes, the control system automatically shuts down the pneumatic diaphragm pump and solenoid valves T3, QJ1, and QC1. Alternatively, when the liquid level in the horizontal transfer tank reaches level 2, the control system automatically shuts down the pneumatic diaphragm pump to prevent overflow. After the liquid level drops to level 1, the control system restarts the pneumatic diaphragm pump.

[0072] ③ When the liquid level in the horizontal transfer tank reaches level 2, the control system automatically starts centrifugal pump No. 3 to transport the wine from the horizontal transfer tank to the wine tanker truck, completing the wine dispensing operation.

[0073] 3) Restore the gravitational potential energy of the wine delivery pipeline

[0074] The effective volume of the "wine transfer buffer tank" is 2m³. 3 The "relay high-level metering tank" has a volume of 1.2 m³. 3 The effective volume of the "wine dispensing relay buffer tank" is 2m³. 3 .

[0075] During wine filling, the gravitational potential energy of the "main wine filling pipeline" is restored, and the "pressure transmitter" of the "intermediate wine filling tank" displays a liquid level value of 0.0 meters for level 1 and 1.5 meters for level 2.

[0076] When the height is 1.5 meters, the effective volume is exactly 2m³. 3 This value needs to be verified and determined during commissioning. As an overflow protection measure, when the liquid level reaches 1.5 meters, the "J1 solenoid valve" will be immediately shut off. During system operation, when the "pressure transmitter" reading is ≤ "liquid level value 2", the "J1 solenoid valve" will be activated to inject wine into the "wine inlet relay buffer tank" through the front-end pipeline. When the "pressure transmitter" reading rises to "liquid level value 2", the "J1 solenoid valve" will be closed and the "X pneumatic diaphragm pump" will be activated to transport the wine to the "relay high-level metering tank".

[0077] The "relay high-level metering tank" features a flat design, with its "pressure transmitter" displaying a level value of 0.0 meters for level 1 and 0.5 meters for level 2 (at 0.5 meters, the effective volume is exactly 1m³). 3 This value needs to be verified and determined during commissioning. As an overflow protection device, when the liquid level reaches 0.5 meters, the "X-type pneumatic diaphragm pump" will be shut down immediately. After the "pressure transmitter" reading rises to "liquid level value 2", the operation is the same as that of the "high-level metering tank".

[0078] When discharging wine, the gravitational potential energy of the "main discharging pipeline" is restored. The "pressure transmitter" of the "discharging relay flushing tank" shows a liquid level value of 0.0 meters for level 1 and 1.5 meters for level 2 (at 1.5 meters, the effective volume is exactly 2m³). 3 This value needs to be verified and determined during commissioning. As an overflow protection, when the liquid level reaches 1.5 meters, the "J1 solenoid valve" will be immediately shut down, and the "pneumatic diaphragm pump" that is supplying wine to the "wine outlet relay buffer tank" will be shut down to prevent overflow. At the same time, the "Z pneumatic diaphragm pump" will be started to transport the wine in the tank to the "high-level pipeline". When the "pressure transmitter" reading is ≤ "liquid level value 1", the "pneumatic diaphragm pump" that supplies wine to the "wine outlet relay buffer tank" will be started again.

[0079] One point that needs to be clarified is that... Figure 1 The markings, such as elevation 1 to elevation 6 and number 1 to Y, are necessary for the clear description of specific embodiments and are in accordance with the requirements of the accompanying drawings.
