Description

Technical Field

[0001] The present invention relates to the technical field of aluminum ladle transfer, and in particular to a forklift-specific vehicle-mounted aluminum liquid transfer and control system. Background Art

[0002] In the production and casting process of aluminum alloys, the transfer of aluminum liquid from the smelting stage to the casting stage is one of the main links that causes oxidation and burning of aluminum alloys. Minimizing this part of burning has been the direction pursued by foundry workers and casting companies for many years.

[0003] The main cause of burnout is the violent agitation of the molten metal when it is transferred from one container to another, which continuously destroys the oxide film on the surface of the molten metal and produces a large amount of oxide. If the agitation of the molten aluminum surface can be avoided during the transfer process, the alloy burnout during this process can be fundamentally reduced.

[0004] Chinese patent application number CN202311346844.7 discloses a system and method for transferring molten aluminum into a low-pressure casting holding furnace to reduce oxidation. The molten aluminum transfer system provided by the above-mentioned prior art only solves the problem of oxidation burning when the molten aluminum is injected from the transfer ladle into the low-pressure casting holding furnace. It does not solve the problem of oxidation burning when transferring from the smelting furnace to the transfer ladle. It fills the transfer ladle with treated molten aluminum and then installs the sealing cover, and then performs the transfer operation to the holding furnace. However, the transfer of aluminum from the smelting furnace to the transfer ladle still requires manual transfer of the molten aluminum into the ladle. This process still produces oxidation burning of aluminum. At the same time, the temperature of the molten aluminum will drop, wasting heat. In addition, the molten aluminum at the ladle mouth is prone to cooling and slagging. Summary of the Invention

[0005] The purpose of the present invention is to provide a forklift-mounted molten aluminum transfer and control system to solve the problem of large amounts of slag generated by the liquid flow impacting the surface of the molten aluminum during the entire process of transferring the molten aluminum into and out of the aluminum transfer ladle, while reducing the temperature loss of the molten aluminum. In addition, the system is convenient for maintenance, reduces the failure rate, and improves the efficiency of aluminum transfer.

[0006] The present invention provides the following technical solutions:

[0007] A forklift-specific onboard aluminum liquid transfer and control system, comprising a ladle body and a ladle cover;

[0008] The outer surface of the package body is provided with a fork sleeve, the top side of the package body is plugged with an inverted aluminum tube, and the top of the package body is provided with a package cover;

[0009] A ventilation solenoid valve is plugged into the package cover, and a liquid level limiting column is plugged into one side of the ventilation solenoid valve on the package cover;

[0010] The ventilation solenoid valve of the package body is connected to a manual ventilation valve through a conduit, and the manual ventilation valve is connected to a second on-off valve and a first on-off valve through a conduit. The second on-off valve and the first on-off valve are respectively connected to a positive pressure bag and a negative pressure bag through conduits, and the positive pressure bag and the negative pressure bag are respectively connected to the micro air compressor through the second two-position three-way solenoid valve and the first two-position three-way solenoid valve.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the angle between the end of the inverted aluminum tube located at one end outside the package and the horizontal plane is 25°.

[0013] The beneficial effects of adopting the above further scheme are:

[0014] Smooth pouring flow: This angle design creates a moderate inclination between the end of the pouring tube and the horizontal plane, which facilitates the smooth flow of molten aluminum during the pouring process. This angle helps the molten aluminum flow naturally, avoiding unstable flow or overflow caused by too small an angle in the pipe.

[0015] Reduced resistance: A moderate tilt angle can reduce resistance during pouring, making the aluminum liquid flow smoother. Compared to a larger angle or a pouring tube parallel to the horizontal plane, a 25° angle can effectively reduce the resistance encountered by the liquid during flow, reduce the loss of flow energy, and thus improve the transfer efficiency.

[0016] Anti-splash: The 25° tilt angle also helps prevent molten aluminum from splashing during the pouring process. This angle design makes the speed and direction of the molten aluminum flow more stable, less likely to cause liquid splashing, and maintains a clean and safe working environment.

[0017] Comfortable operation: The moderate tilt angle makes the operator more comfortable when transferring aluminum liquid. The design of the aluminum pouring tube conforms to the principles of ergonomics, allowing the operator to adjust the posture naturally during operation, reducing discomfort and fatigue during operation.

[0018] Furthermore, the bag is limitedly connected to the forklift's cantilever fork through a fork sleeve, and when sucking molten aluminum, the bag is driven by the forklift's cantilever fork to deflect 15°, and the inverted aluminum tube is inserted into the water inlet.

[0019] The beneficial effects of adopting the above further scheme are:

[0020] Stability and safety: The fork sleeve is connected to the forklift's beam fork limiter, ensuring that the bag is firmly fixed to the forklift. This connection method not only improves the stability of the entire transfer bag, but also prevents accidental falling or tilting due to unstable connection during the transfer process, ensuring operational safety.

[0021] Easy Operation: When drawing molten aluminum, the ladle is deflected 15° by the forklift's forklift, allowing the pouring tube to be inserted into the water inlet. This design simplifies the operation process, allowing the operator to complete the pouring process simply by moving the forklift, eliminating the need for additional manual operation and improving operational convenience and efficiency.

[0022] Accuracy: The forklift's forklift's 15° deflection of the ladle allows the aluminum tube to be accurately inserted into the water inlet. This automated operation ensures smooth flow of molten aluminum into the water inlet, avoiding overflow or waste caused by inaccurate operation.

[0023] Saving manpower: Since the ladle is deflected by the forklift's lifting beam, the operator does not need to perform additional physical labor during the process of sucking out the molten aluminum. This not only reduces the labor intensity of the operation, but also saves human resources and improves work efficiency.

[0024] Strong adaptability: This design is suitable for various work scenarios and work requirements. Whether it is transferring molten aluminum or sampling, it can be completed by adjusting the forklift movement. This flexibility and versatility allows this transfer bag to adapt to different production needs and improve the use value of the equipment.

[0025] Furthermore, the end of the inverted aluminum tube at one end inside the encasement is 30 mm away from the bottom surface of the encasement, and when the encasement is placed horizontally, the slope of the inverted aluminum tube is the same as the slope of the opening of the holding furnace.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] Stable Flow: The design of the aluminum pouring tube at one end of the ladle is 30mm from the bottom of the ladle, which helps maintain the stability of the aluminum liquid flow. This distance is neither too long nor too short, ensuring that the aluminum liquid flows smoothly from the aluminum pouring tube, avoiding problems such as poor flow or blockage caused by improper pipe positioning.

[0028] Holding Furnace Compatibility: The inclination of the aluminum pouring tube matches the inclination of the holding furnace opening. This means that during transfer, the molten aluminum can flow smoothly into the holding furnace, eliminating the problems of poor flow or incomplete pouring due to pipe angle issues. This design ensures accurate and efficient transfer.

[0029] Convenient operation: The 30mm distance design allows operators to easily control the flow of molten aluminum, making operation more convenient. The design of the same slope between the pouring tube and the holding furnace opening makes operation more intuitive, allowing operators to more accurately control the pouring direction and speed of the molten aluminum.

[0030] Safe and reliable: This design not only ensures the smooth flow and transfer accuracy of the molten aluminum, but also takes into account the safety of the operator, avoiding potential safety hazards caused by the molten aluminum overflowing or not being poured into the target position.

[0031] Furthermore, a first positive pressure gauge and a second flow valve are sequentially connected between the second on-off valve and the positive pressure bag through a conduit, and a second positive pressure gauge is installed on the positive pressure bag.

[0032] The beneficial effects of adopting the above further scheme are:

[0033] Accurate pressure control: The first positive pressure gauge, located on the conduit between the second on-off valve and the positive pressure bag, monitors the positive pressure during the aluminum transfer process in real time. This design ensures stable pressure in the positive pressure bag, preventing unstable aluminum flow caused by excessive or insufficient pressure.

[0034] Flexible flow control: A second flow valve connected to the first positive pressure gauge allows real-time adjustment of the aluminum liquid flow rate based on pressure changes in the first positive pressure gauge. This design ensures precise control of the aluminum liquid's flow rate and volume during the transfer process, ensuring both quality and efficiency.

[0035] Controllability of process parameters: The presence of the first positive pressure gauge allows operators to monitor the pressure in the positive pressure bag at all times and adjust the flow valve as needed to meet the different process requirements for aluminum liquid transfer. This controllability helps improve the adjustability of process parameters and the flexibility of the aluminum liquid transfer process.

[0036] Safety Assurance: A second positive pressure gauge is installed on the positive pressure package as a backup pressure monitoring device. This design provides backup pressure monitoring in the event of a failure or anomaly in the primary positive pressure gauge. This ensures system safety and stability, preventing unexpected situations caused by uncontrolled pressure during the transfer process.

[0037] Convenient troubleshooting: The second positive pressure gauge installed on the positive pressure package serves as an important reference for troubleshooting. When a system anomaly occurs, operators can quickly locate and eliminate the problem by comparing the pressure data from the first and second positive pressure gauges, ensuring continuous and stable system operation.

[0038] Automatic Regulation: The linkage between the first positive pressure gauge and the second flow valve enables a certain degree of automatic regulation. If the pressure of the molten aluminum changes during transfer, the system automatically adjusts the second flow valve based on the feedback signal from the first positive pressure gauge, ensuring stable flow rate and flow rate.

[0039] Furthermore, an air filter is connected between the positive pressure bag and the second two-position three-way solenoid valve via a conduit.

[0040] The beneficial effects of adopting the above further scheme are:

[0041] Protecting system equipment: The presence of air filters effectively prevents impurities, dust, particles, and other contaminants in the air from entering the system's positive pressure package and its connected components. This function of preventing impurities from entering can extend the service life of system equipment and reduce equipment failure rate and maintenance costs.

[0042] Preventing contamination of molten aluminum: During the transfer process, if the air contains impurities and pollutants, it may have a negative impact on the quality of the molten aluminum. By installing an air filter, the air can be effectively purified to ensure that no impurities in the air enter the positive pressure bag, thereby ensuring the purity and quality of the molten aluminum.

[0043] Maintaining a Clean Operating Environment: Air filters also help maintain a clean operating environment. In industrial production, a clean working environment is crucial to both the production process and the health of operators. By purifying the air, air filters can reduce dust and pollutants in the air, improving the operating environment and enhancing work comfort and safety.

[0044] Improving the purity of molten aluminum: The use of air filters can effectively improve the purity of molten aluminum. During the transfer process, if there are impurities in the air, it may cause contamination of the molten aluminum and affect product quality. By purifying the air, air filters can ensure the purity of the air in the positive pressure bag, ensuring the quality and purity of the molten aluminum.

[0045] Protecting the health of operators: In industrial production, prolonged exposure to polluted air can have health consequences for operators. Air filters can reduce harmful substances in the air, lowering the risk of operator exposure and ensuring their health and safety.

[0046] System stability and efficiency: Keeping the air inside the positive pressure bag clean and pure helps ensure the stability and efficiency of the system. Clean air can reduce resistance and friction in the system, improve system efficiency, and also reduce equipment wear and tear and extend its service life.

[0047] Convenient Operation and Maintenance: The air filter makes system operation and maintenance more convenient. Operators can regularly check and replace the air filter to ensure the system is always in good working condition. This regular maintenance contributes to stable system operation and reduces the possibility of system failures and repairs.

[0048] Environmental protection and energy saving: The installation of air filters can reduce exhaust emissions and environmental pollution. At the same time, air purification can improve the energy efficiency of the system, reduce energy consumption, and comply with the concept of energy conservation and environmental protection.

[0049] Furthermore, a first negative pressure gauge and a first flow valve are sequentially connected between the first on-off valve and the negative pressure bag through a conduit, and a second negative pressure gauge is installed on the negative pressure bag.

[0050] The beneficial effects of adopting the above further scheme are:

[0051] Accurate negative pressure control: The first negative pressure gauge, installed between the negative pressure bag and the first on-off valve, monitors the pressure inside the bag in real time. This real-time monitoring ensures that the system's negative pressure remains within the set range and regulates the air flow inside the bag via the first flow valve. This precise negative pressure control ensures stability and accuracy during the aluminum liquid aspiration process.

[0052] Flexible air flow control: The first flow valve allows the operator to flexibly adjust the air flow within the vacuum bag as needed. By adjusting the first flow valve, the air flow rate within the vacuum bag can be controlled, achieving precise control over the aluminum liquid suction process. This flexibility allows adjustment based on specific process requirements and the aluminum liquid suction situation, improving operational flexibility and efficiency.

[0053] Real-time monitoring and adjustment: A second negative pressure gauge, mounted on the negative pressure package, monitors pressure changes within the package in real time. This real-time monitoring allows operators to understand the system's operating status at all times and adjust the first flow valve promptly to ensure stability and accuracy during the aluminum liquid suction process. This real-time monitoring and adjustment ensures the stability and reliability of the system's operation.

[0054] System safety: The first and second negative pressure gauges provide system safety. These gauges monitor changes in negative pressure in the system. Once abnormal negative pressure occurs, an alarm is sounded and the aluminum liquid suction process is stopped, ensuring the safety of operators and equipment.

[0055] Control of process parameters: Through the cooperation of the first negative pressure gauge and the first flow valve, process parameters such as air velocity and flow rate during the aluminum liquid suction process can be accurately controlled. This precise control helps to ensure the quality of the aluminum liquid and the stability of the process, and improves the efficiency and quality of the aluminum liquid suction process.

[0056] Convenient Operation: This design allows the operator to intuitively understand the pressure of the vacuum bag and control the aluminum liquid suction process by adjusting the first flow valve. This simple and intuitive operation method allows the operator to quickly and accurately adjust the system, improving the convenience and efficiency of operation.

[0057] Stable system operation: The combination of these advantages makes the entire system more stable and reliable during operation. Real-time monitoring and adjustment, precise negative pressure control and air flow regulation ensure the stability and accuracy of the aluminum liquid suction process, thereby improving the operating efficiency and reliability of the entire system.

[0058] Quality Control and Process Optimization: This design not only ensures stability and accuracy during the aluminum liquid suction process, but also enables precise control of aluminum liquid quality and process parameters. This is of great significance for improving product quality and optimizing process flows, providing enterprises with more advantages and competitiveness.

[0059] The beneficial effects of the present invention are:

[0060] Reasonable Structural Design: The ladle body and lid are designed with exceptional rationality, particularly in the fork sleeve arrangement. These fork sleeves ensure a secure and reliable connection between the ladle body and the forklift. By connecting to the forklift's forks, the transfer ladle is securely fixed to the forklift, preventing it from shaking or falling during movement or operation. This design not only improves operational safety but also ensures stability and reliability during the aluminum liquid suction and transfer process.

[0061] Easy Operation: The inverted aluminum tube design makes the entire aluminum liquid extraction process simpler and more efficient. When the forklift's fork lifts the ladle and deflects it 15°, the inverted aluminum tube smoothly inserts into the water inlet, allowing the aluminum liquid to be smoothly extracted. This design avoids cumbersome operation steps, reduces operator workload, and improves operational efficiency.

[0062] Reasonable slope design: The angle between the end of the pouring tube and the outside of the ladle is 25°, a carefully considered choice. This angle allows the molten aluminum to flow smoothly from the pouring tube without excessive resistance or splashing. Furthermore, the design of the pouring tube end 30mm from the bottom of the ladle ensures stable and continuous flow of the molten aluminum, avoiding flow problems caused by improper pipe positioning.

[0063] Strong adaptability: This transfer bag is designed to accommodate different types of holding furnaces. The inclination of the aluminum pouring tube matches the inclination of the furnace opening. This design ensures that the molten aluminum flows smoothly into the holding furnace during the transfer process, preventing waste or overflow due to pipe position or angle issues, ensuring accurate and stable operation.

[0064] Complete Functionality: The cover features a vent solenoid valve and a liquid level stopper, two functional modules that make operation more convenient and safer. The vent solenoid valve controls the flow rate and volume of the molten aluminum, ensuring stability and fluidity during the transfer process. The liquid level stopper monitors the liquid level and automatically stops transfer once the preset level is reached, preventing overflow and waste.

[0065] Manual vent valve and safety: The presence of a manual vent valve allows the operator to manually control the flow of molten aluminum, which is very useful in emergency situations. If the transfer of molten aluminum needs to be stopped urgently, the operator can directly operate the manual vent valve to quickly cut off the flow of molten aluminum, ensuring the safety of the workplace and the operator.

[0066] Functions of the first and second on-off valves: These valves enable precise control of the flow of molten aluminum. These valves control the flow of the positive and negative pressure ladle, respectively, making the transfer process more controllable and stable. Operators can adjust these valves as needed to ensure the flow rate and flow rate meet process requirements.

[0067] The role of positive and negative pressure bags: These bags play a key role in this system. The positive bag provides stable positive pressure, helping to smoothly push the molten aluminum to the target location and ensure a smooth transfer process. The negative pressure bag helps expel air from the bag, creating a negative pressure environment, thereby improving the efficiency and quality of aluminum liquid extraction.

[0068] Pressure and flow monitoring and adjustment: The pressure gauge and flow valve allow operators to monitor and adjust the system's pressure and flow in real time. This monitoring and adjustment ensures stability and accuracy during the aluminum transfer process, preventing abnormalities caused by pressure or flow fluctuations.

[0069] The second two-position three-way solenoid valve and the first two-position three-way solenoid valve function as automated control systems. These two solenoid valves automatically connect and disconnect the positive and negative pressure packages according to a pre-set program, automating the aluminum liquid transfer process. This automated control significantly improves operational convenience and efficiency.

[0070] Importance of air filters: Air filters ensure air quality in the system and prevent impurities from entering the positive and negative pressure ladle. This helps prevent impurities from affecting the quality of the molten aluminum and the working environment, ensuring the stability of the transfer process and the purity of the molten aluminum.

[0071] The system's comprehensive advantages lie in its integration of multiple functional modules into a comprehensive aluminum transfer control system. From aluminum extraction, flow control, pressure regulation, to automated operation, every step has been carefully considered and designed. This comprehensive advantage ensures the system's high reliability, stability, and ease of operation, providing a reliable aluminum transfer solution for industrial production.

[0081] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0082] See also Figure 1 As shown, the embodiments provided by the present invention are:

[0083] Example 1

[0084] A forklift-specific onboard aluminum liquid transfer and control system includes a bag body 18 and a bag cover 19. The outer surface of the bag body 18 is provided with a fork sleeve 21, and the bag body 18 is connected to the forklift's cantilever fork through the fork sleeve 21.

[0085] A cover 19 is provided on the top of the package body 18. The cover 19 is composed of a steel plate shell and a heat-insulating material filler. The ventilation solenoid valve 1 is plugged into the cover 19. A liquid level limit column 17 is plugged into one side of the ventilation solenoid valve 1 on the cover 19.

[0086] See also Figure 1-2As shown, when drawing molten aluminum, the ladle 18 is deflected 15° by the forklift's fork, allowing the pouring tube 20 to be inserted into the water inlet 22. The fork sleeve 21 is connected to the forklift's fork, ensuring that the ladle 18 is securely fixed to the forklift. This connection not only improves the stability of the entire transfer ladle, but also prevents accidental detachment or tilting due to unstable connection during the transfer process, ensuring safe operation. When drawing molten aluminum, the ladle 18 is deflected 15° by the forklift's fork, allowing the pouring tube 20 to be inserted into the water inlet 22. This design simplifies the operation process, allowing the operator to complete the pouring process simply by moving the forklift, eliminating the need for additional manual operation, improving convenience and efficiency. The forklift's fork, which drives the ladle 18 15°, allows the pouring tube 20 to be accurately inserted into the water inlet 22. This automated operation ensures smooth flow of molten aluminum into the water inlet 22, preventing spillage or waste due to inaccurate operation. Because the ladle 18 is deflected by the forklift's forks, the operator does not need to perform additional physical labor during the molten aluminum extraction process. This not only reduces labor intensity, but also saves manpower and improves work efficiency. This design is adaptable to various work scenarios and requirements. Whether transferring molten aluminum or sampling, it can be completed by adjusting the forklift's movements. This flexibility and versatility allows the transfer ladle to adapt to different production needs, increasing the equipment's usability.

[0087] See also Figure 1 and Figure 3As shown, an aluminum pouring tube 20 is inserted into one side of the top of the ladles 18. The angle between the end of the ladles 20, located on the outside of the ladles 18, and the horizontal plane is 25°. This angle creates a moderate inclination between the end of the ladles 20 and the horizontal plane, facilitating smooth flow of the molten aluminum during pouring. This angle helps the molten aluminum flow naturally, preventing unstable flow or overflow caused by a narrow angle. This moderate inclination reduces resistance during pouring, ensuring smoother flow. Compared to ladles 20 with larger angles or parallel to the horizontal plane, a 25° angle effectively reduces resistance to liquid flow, minimizing energy loss and improving pouring efficiency. The 25° inclination also helps prevent spillage during pouring. This design stabilizes the speed and direction of the molten aluminum flow, minimizing spillage and maintaining a clean and safe working environment. The moderate inclination also makes pouring more comfortable for operators. The pouring tube 20 is ergonomically designed, allowing the operator to adjust their posture naturally during operation, reducing discomfort and fatigue. The tip of the pouring tube 20, located within the ladle 18, is 30 mm from the bottom of the ladle 18. When the ladle 18 is positioned horizontally, the inclination of the pouring tube 20 is the same as the inclination of the opening of the holding furnace 23. This 30 mm distance from the tip of the pouring tube 20 within the ladle 18 helps maintain the flow stability of the molten aluminum. This distance, neither too long nor too short, ensures smooth flow of the molten aluminum from the pouring tube 20, avoiding flow obstructions or blockages caused by improperly positioned pipes. The inclination of the pouring tube 20 is the same as the inclination of the opening of the holding furnace 23, ensuring smooth flow of the molten aluminum into the holding furnace 23 during transfer, eliminating flow obstructions or incomplete pouring due to pipe angle issues. This design ensures accurate and efficient transfer. The 30mm distance design allows operators to easily control the flow of molten aluminum, making operation more convenient. The design of the pouring tube 20 and the opening of the holding furnace 23 with the same slope makes operation more intuitive, allowing the operator to more accurately control the pouring direction and speed of the molten aluminum. This design not only ensures the smooth flow and accuracy of the molten aluminum, but also takes into account the safety of the operator. It avoids potential safety hazards caused by molten aluminum overflow or mis-pour. The end of the pouring tube 20 located inside the cladding 18 is made of silicon carbide ceramic material, while the end of the pouring tube 20 located outside the cladding 18 is made of aluminum titanate tube with insulation wool layer and carbon steel.

[0088] When a forklift-specific onboard aluminum liquid transfer and control system based on Example 1 is used:

[0089] Rational Structural Design: The design of the ladle body 18 and lid 19 is exceptionally rational, primarily exemplified by the placement of the fork sleeve 21. This fork sleeve 21 ensures a secure and reliable connection between the ladle body 18 and the forklift. By connecting to the forklift's forks, the transfer ladle is securely fastened to the forklift, preventing it from shaking or falling during movement or operation. This design not only enhances operational safety but also ensures stability and reliability during the aluminum molten liquid suction and transfer processes.

[0090] Easy Operation: The design of the aluminum inlet tube 20 simplifies and improves the entire aluminum liquid extraction process. When the forklift's fork lifts the container 18 and deflects it 15°, the aluminum inlet tube 20 smoothly inserts into the water inlet 22, allowing the aluminum liquid to be smoothly extracted. This design eliminates cumbersome steps, reduces operator workload, and improves efficiency.

[0091] Reasonable Slope Design: The angle between the end of the pouring tube 20 and the outside of the cladding body 18 is 25°, a carefully considered choice. This angle allows the molten aluminum to flow smoothly from the pouring tube 20 without excessive resistance or splashing. Furthermore, the design of the end of the pouring tube 20 30mm from the bottom of the cladding body 18 ensures stable and continuous flow of the molten aluminum, avoiding flow problems caused by improper pipe positioning.

[0092] Strong adaptability: The design of this transfer package takes into account the conditions of different types of holding furnaces 23. Therefore, the design slope of the aluminum pouring tube 20 is the same as the slope of the opening of the holding furnace 23. This design ensures that the molten aluminum can flow smoothly into the holding furnace 23 during the transfer process, without causing waste or overflow of molten aluminum due to the position or angle of the pipe, ensuring accurate and stable operation.

[0093] Complete Functionality: The cover 19 is connected to a vent solenoid valve 1 and a liquid level stopper 17. These two functional modules make operation more convenient and safer. The vent solenoid valve 1 controls the flow rate and volume of the molten aluminum, ensuring stability and fluidity during the transfer process. The liquid level stopper 17 monitors the liquid level and automatically stops transfer once the preset level is reached, preventing overflow and waste.

[0094] Example 2

[0095] like Figure 4 and Figure 5 As shown, the utility model proposes a forklift-specific onboard aluminum liquid transfer and control system. Compared with the first embodiment, this embodiment also includes:

[0096] The vent solenoid valve 1 in the bladder 18 is connected to a manual vent valve 2 via a conduit. The manual vent valve 2 is connected to a second on-off valve 6 and a first on-off valve 3 via a conduit. The second on-off valve 6 and the first on-off valve 3 are connected to a positive pressure bag 11 and a negative pressure bag 7, respectively, via conduits. A first positive pressure gauge 8 and a second flow valve 9 are connected in sequence between the second on-off valve 6 and the positive pressure bag 11 via conduits. A second positive pressure gauge 12 is mounted on the positive pressure bag 11. The first positive pressure gauge 8, located on the conduit between the second on-off valve 6 and the positive pressure bag 11, monitors the positive pressure during the transfer process. This design ensures stable pressure within the positive pressure bag 11, preventing unstable flow caused by excessive or insufficient pressure. The second flow valve 9, connected after the first positive pressure gauge 8, adjusts the flow rate of the molten aluminum in real time based on pressure changes in the first positive pressure gauge 8. This design ensures precise control of the flow rate and volume of the molten aluminum during the transfer process, ensuring both quality and efficiency. The presence of the first positive pressure gauge 8 allows the operator to monitor the pressure in the positive pressure bag 11 at all times and adjust the flow valve as needed to meet the different process requirements for molten aluminum transfer. This controllability helps improve the adjustability of process parameters and the flexibility of the molten aluminum transfer process. The second positive pressure gauge 12 is installed on the positive pressure bag 11 as a backup pressure monitoring device. This design provides a backup pressure monitoring function in the event of a failure or abnormality in the first positive pressure gauge 8. This ensures the safety and stability of the system and avoids unexpected situations caused by pressure loss during the molten aluminum transfer process. The second positive pressure gauge 12 installed on the positive pressure bag 11 serves as an important reference for troubleshooting. If a system anomaly occurs, the operator can quickly locate and resolve the problem by comparing the pressure data from the first and second positive pressure gauges 12, ensuring the continued stable operation of the system. The linkage design of the first positive pressure gauge 8 and the second flow valve 9 enables the system to achieve a certain degree of automatic adjustment. When pressure changes during the aluminum transfer process, the system automatically adjusts the second flow valve 9 based on feedback from the first positive pressure gauge 8 to ensure stable aluminum flow rate and flow rate. A first negative pressure gauge 4 and a first flow valve 5 are connected in sequence between the first on-off valve 3 and the negative pressure bag 7 via a conduit. A second negative pressure gauge 10 is mounted on the negative pressure bag 7. The first negative pressure gauge 4, installed between the negative pressure bag 7 and the first on-off valve 3, monitors the pressure within the bag in real time.

This precise negative pressure control ensures stability and accuracy during the aluminum transfer process. The provision of the first flow valve 5 allows the operator to flexibly adjust the air flow within the bag 7 as needed. Adjusting the first flow valve 5 controls the air flow rate within the bag, thereby achieving precise control of the aluminum transfer process.This flexibility allows adjustments based on specific process requirements and the aluminum liquid suction process, improving operational flexibility and efficiency. A second negative pressure gauge 10, mounted on the negative pressure bag 7, monitors pressure changes within the bag in real time. This real-time monitoring allows operators to understand the system's operating status at all times and adjust the first flow valve 5 promptly to ensure stability and accuracy during the aluminum liquid suction process. This real-time monitoring and adjustment ensures the stability and reliability of system operation. The installation of the first negative pressure gauge 4 and the second negative pressure gauge 10 provides system safety. These pressure gauges monitor system negative pressure changes and, if abnormal negative pressure occurs, promptly issue an alarm and halt the aluminum liquid suction process, ensuring the safety of operators and equipment. The coordination of the first negative pressure gauge 4 and the first flow valve 5 allows precise control of process parameters during the aluminum liquid suction process, such as air flow rate and flow rate. This precise control helps ensure aluminum liquid quality and process stability, improving the efficiency and quality of the aluminum liquid suction process. This design allows operators to intuitively understand the pressure within the negative pressure bag 7 and control the aluminum liquid suction process by adjusting the first flow valve 5. This simple and intuitive operation method allows operators to quickly and accurately adjust the system, improving operational convenience and efficiency. The combination of these advantages makes the entire system more stable and reliable during operation.

This is of great significance for improving product quality and optimizing process flows, providing companies with greater advantages and competitiveness. The positive pressure package 11 and the negative pressure package 7 are connected to a micro-air compressor 15 via a second two-position three-way solenoid valve 14 and a first two-position three-way solenoid valve 16, respectively. An air filter 13 is connected between the positive pressure package 11 and the second two-position three-way solenoid valve 14 via a conduit. The air filter 13 effectively prevents impurities, dust, particulate matter, and other contaminants from entering the positive pressure package 11 and its connected components. This impurity prevention feature extends the service life of system equipment, reducing equipment failure rates and maintenance costs. During the aluminum liquid transfer process, impurities and contaminants in the air can negatively impact the quality of the molten aluminum. The air filter 13 effectively purifies the air, ensuring that no impurities enter the positive pressure ladle 11, thereby ensuring the purity and quality of the molten aluminum. The air filter 13 also helps maintain a clean operating environment. In industrial production, a clean working environment is crucial to both the production process and the health of operators. By purifying the air, the air filter 13 reduces dust and contaminants in the air, improving the operating environment and enhancing both comfort and safety.The use of air filter 13 effectively improves the purity of molten aluminum. During the transfer process, impurities in the air can contaminate the molten aluminum and affect product quality. By purifying the air, air filter 13 ensures the purity of the air in the positive pressure drum 11, guaranteeing the quality and purity of the molten aluminum. In industrial production, prolonged exposure to polluted air can pose health risks to operators. The installation of air filter 13 reduces harmful substances in the air, lowering the risk of operator exposure and safeguarding their health and safety. Maintaining clean and pure air within the positive pressure drum 11 helps ensure stable and efficient system operation. Clean air reduces resistance and friction in the system, improving system efficiency, while also reducing equipment wear and extending its service life. The installation of air filter 13 facilitates system operation and maintenance. Operators can regularly check and replace air filter 13 to ensure the system is always in good working condition. This regular maintenance contributes to stable system operation and reduces the possibility of system failures and repairs. The installation of air filter 13 also reduces exhaust emissions and environmental pollution. At the same time, air purification can improve the energy efficiency of the system, reduce energy consumption, and comply with the concept of energy conservation and environmental protection.

[0097] See also Figure 2 、 Figure 4 and Figure 5 As shown, the working process of absorbing aluminum liquid is as follows:

[0098] Use a forklift to place the aluminum package 18 on Figure 2 In the position shown, turn on the rotary switch XAQ, turn the selection switch CD to the negative pressure side, press the liquid suction switch 2AQ, manually adjust the first flow valve 5 to start sucking molten aluminum. When the molten aluminum reaches the liquid level limit column 17, the limit switch 1XK is turned on, and the system automatically stops sucking molten aluminum. The forklift driver quickly withdraws the transfer ladle from the transfer ladle at 40° as shown in the figure, manually closes the first flow valve 5, and then presses the reset button 1AT. The molten aluminum suction process ends.

[0099] See also Figure 3 、 Figure 4 and Figure 5 As shown, the process of transferring aluminum liquid is as follows:

[0100] The forklift places the aluminum package 18 on Figure 3 In the position shown, turn on the rotary switch XAQ, turn the selection switch CD to the positive pressure side, press the aluminum liquid extrusion switch 1AQ, manually adjust the second flow valve 9, start to extrude the aluminum liquid, and when the aluminum liquid reaches the required liquid level, press the stop button 3AQ, the system stops transferring the aluminum liquid, and the forklift driver quickly withdraws the aluminum transfer ladle from the aluminum transfer ladle in the direction of 25° as shown in the figure, manually close the second flow valve 9, and then press the reset button 1AT, and the aluminum liquid transfer process ends.

[0101] When the present invention is in use, the aluminum transfer ladle body 18 is in a sealed state. A forklift with an oblique side shift function tilts the aluminum transfer ladle body 15° and inserts it into the opening of the smelting furnace along the tilt direction (40°) of the ladle mouth, starts the negative pressure aluminum suction switch, and fills the aluminum transfer ladle with the processed aluminum liquid in the smelting furnace. After that, the forklift moves the aluminum transfer ladle out of the smelting furnace, resets the direction of the ladle body (at this time the ladle mouth is tilted 25°), and moves the aluminum transfer ladle to the work station of the low-pressure casting insulation furnace. Using the side shift function of the forklift, the port of the ladle mouth is inserted in the direction of 25° below the aluminum liquid level inside the low-pressure casting insulation furnace, and the positive pressure aluminum liquid injection switch of the aluminum transfer system is started. The aluminum liquid in the aluminum transfer ladle is pushed out by pressurized air and injected into the interior of the low-pressure casting insulation furnace. The oxide film on the surface of the aluminum liquid will not be disturbed during the injection of the aluminum liquid.

[0102] When the control system of a forklift-specific onboard aluminum liquid transfer and control system according to Example 2 is used:

[0103] Manual vent valve 2 and safety: The presence of manual vent valve 2 allows the operator to manually control the flow of molten aluminum, which is very useful in emergency situations. If the transfer of molten aluminum needs to be stopped urgently, the operator can directly operate manual vent valve 2 to quickly cut off the flow of molten aluminum, ensuring the safety of the workplace and the operator.

[0104] Functions of the first on-off valve 3 and the second on-off valve 6: The design of the first on-off valve 3 and the second on-off valve 6 enables precise control of the flow of molten aluminum. These valves control the flow of the positive pressure bag 11 and the negative pressure bag 7, respectively, making the transfer process more controllable and stable. Operators can adjust these valves as needed to ensure that the flow rate and flow rate of the molten aluminum meet process requirements.

[0105] The functions of the positive pressure bag 11 and the negative pressure bag 7: These two bags play a key role in this system. The positive pressure bag 11 provides stable positive pressure, helping to smoothly push the molten aluminum to the target location and ensure a smooth transfer process. The negative pressure bag 7 helps expel air from the bag body 18, creating a negative pressure environment and improving the efficiency and quality of the molten aluminum.

[0106] Pressure and flow monitoring and adjustment: The pressure gauge and flow valve allow operators to monitor and adjust the system's pressure and flow in real time. This monitoring and adjustment ensures stability and accuracy during the aluminum transfer process, preventing abnormalities caused by pressure or flow fluctuations.

[0107] The functions of the second two-position three-way solenoid valve 14 and the first two-position three-way solenoid valve 16 are as follows: These two solenoid valves enable automated control of the system. They automatically control the connection and disconnection of the positive pressure bag 11 and the negative pressure bag 7 according to a preset program, automating the aluminum liquid transfer process. This automated control significantly improves operational convenience and efficiency.

[0108] Importance of air filter 13: The installation of air filter 13 ensures the air quality in the system and prevents impurities from entering the positive pressure bag 11 and the negative pressure bag 7. This helps to prevent impurities from affecting the quality of the molten aluminum and the working environment, and ensures the stability of the transfer process and the purity of the molten aluminum.

[0109] The system's comprehensive advantages lie in its integration of multiple functional modules into a comprehensive aluminum transfer control system. From aluminum extraction, flow control, pressure regulation, to automated operation, every step has been carefully considered and designed. This comprehensive advantage ensures the system's high reliability, stability, and ease of operation, providing a reliable aluminum transfer solution for industrial production.
