Description

Technical Field

[0001] This invention belongs to the technical field of aluminum liquid control devices, specifically relating to an automatic aluminum liquid control device and a flow control method. Background Technology

[0002] In aluminum casting and smelting processes, precise control of molten aluminum flow rate is crucial for ensuring product quality and production efficiency. Traditional molten aluminum flow control relies heavily on manual operation or simple mechanical devices, with operators adjusting stopcocks or valve openings based on experience. This is not only labor-intensive and creates a hazardous operating environment, but also makes it difficult to achieve precise and stable continuous flow rate regulation. Especially with the increasing demands for automation and intelligent production, manual control is susceptible to subjective factors, often resulting in fluctuations in molten aluminum flow rate and inaccurate pouring volumes. This leads to defects in castings such as incomplete filling, cold shuts, or gas inclusions, affecting product yield. Therefore, there is a need to develop an aluminum molten aluminum flow control device that can adapt to the high-temperature molten aluminum environment and achieve precise, automatic, and reliable regulation to improve the automation level and process stability of aluminum processing production.

The control device includes a plug, a forward and backward moving drive mechanism for controlling the plug to move axially along the molten aluminum outflow hole, and a left and right moving drive mechanism for controlling the plug to move radially along the molten aluminum outflow hole.

[0004] As a preferred embodiment of the above technical solution, the plug is cone-shaped, and a fixed rod is fixedly connected to the center of the bottom surface of the plug. The fixed rod is fixedly connected to an adjusting rod through several connecting plates. The adjusting rod is parallel to the fixed rod. The front-to-back movement drive mechanism includes a front-to-back movement slide plate and an electric push rod. The front-to-back movement slide plate is slidably mounted on the front-to-back slide rails, which are parallel to the fixed rod. The electric push rod drives the front-to-back movement slide plate to move on the front-to-back slide rails. The adjusting rod is connected to the front-to-back movement slide plate. The left-to-right movement drive mechanism includes a left-to-right movement frame and a cylinder. The left-to-right movement frame is slidably mounted on the left-to-right slide rails. The cylinder drives the left-to-right movement frame to move on the left-to-right slide rails. The front-to-back slide rails are fixed to the left-to-right movement frame.

[0005] As a preferred embodiment of the above technical solution, the left and right movable frame includes a frame body, a mounting plate, and left and right sliding plates. The front and rear slide rails are fixed on the mounting plate. A vertical plate is fixedly connected to one side of the mounting plate.

The retention of the manual adjustment mechanism further enhances the equipment's flexibility in responding to emergencies and improves operational safety. Attached Figure Description

[0017] like Figure 1-2 As shown, an automatic control device for molten aluminum is described. The molten aluminum is stored in an aluminum molten aluminum insulation tank 1, which has an aluminum molten aluminum outlet hole 2. The molten aluminum flows out of the aluminum molten aluminum insulation tank 1 through the outlet hole 2. The control device includes a plug 3, a forward and backward movement drive mechanism for controlling the molten aluminum 3 to move axially along the outlet hole 2, and a left and right movement drive mechanism for controlling the molten aluminum 3 to move radially along the outlet hole 2. By using the automatic drive mechanisms to drive the plug 3 to move forward and backward and left and right, the flow rate of molten aluminum in the outlet hole 2 is automatically controlled.

[0018] Furthermore, the plug 3 is cone-shaped, and a fixed rod 4 is fixedly connected to the center of the bottom surface of the plug 3. The fixed rod 4 is fixedly connected to an adjusting rod 6 through several connecting plates 5. The adjusting rod 6 is parallel to the fixed rod 4. The front-to-back movement drive mechanism includes a front-to-back movement slide plate 7 and an electric push rod 8. The front-to-back movement slide plate 7 is slidably mounted on a front-to-back slide rail 9, which is parallel to the fixed rod 4. The electric push rod 8 drives the front-to-back movement slide plate 7 to move on the front-to-back slide rail 9. The adjusting rod 6 is connected to the front-to-back movement slide plate 7. The left-to-right movement drive mechanism includes a left-to-right movement frame and a cylinder 11. The left-to-right movement frame is slidably mounted on a left-to-right slide rail 12. The cylinder 11 drives the left-to-right movement frame to move on the left-to-right slide rail 12. The front-to-back slide rail 9 is fixed to the left-to-right movement frame. Heat insulation plates can be installed around the electric push rod 8 to reduce the impact of high-temperature molten aluminum on the electric push rod 8. The left-to-right slide rail 12 is mounted on a fixed frame located on one side of the molten aluminum insulation box 1. Cylinder 11 can also be replaced by an electric push rod. To improve control accuracy, a motor-driven lead screw can also be used.

[0019] Furthermore, the left-right movable frame includes a frame body 13, a mounting plate 14, and left and right sliding plates 15. Front and rear slide rails 9 are fixed to the mounting plate 14. A vertical plate 16 is fixedly connected to one side of the mounting plate 14. The vertical plate 16 has several vertically arranged elongated holes, and adjusting bolts are installed in the elongated holes. The adjusting bolts are threadedly connected to the upper end of the frame body 13. The left and right sliding plates 15 are slidably mounted on the left and right slide rails 12 and are fixedly connected to the lower end of the frame body 13. Loosening the adjusting bolts allows them to move up and down within the elongated holes, adjusting the height of the mounting plate 14, thereby adjusting the height of the plug 3.

[0020] Furthermore, the fixing rod 4 is connected to the plug 3 via a universal ball joint 18. The plug 3 can be adjusted in any direction within a certain angle range, so that the plug 3 can automatically adjust during the process of being inserted into the aluminum liquid outflow hole 2, thereby completely blocking the aluminum liquid outflow hole 2.

[0021] Furthermore, the adjusting rod 6 is fitted with several sliding sleeves 19, and the adjusting rod 6 has a keyway with several keys inside. The keys are fixedly connected to the sliding sleeves 19, and the sliding sleeves 19 are connected to the forward and backward moving slide plate 7 via a vertically arranged connecting plate 10. A locking mechanism for locking the adjusting rod 6 is installed on the connecting plate 10, and a handle 20 is fixedly connected to one end of the adjusting rod 6. After the locking mechanism is unlocked, the adjusting rod 6 can be pushed and pulled by the handle 20, which drives the fixed rod 4 to move, thereby realizing manual adjustment of the aluminum liquid flow rate.

[0022] Furthermore, the locking mechanism includes a pressure plate 21, a fixing plate 22 above the pressure plate 21, a connecting plate 10 fixedly connected to the fixing plate 22, a threaded hole on the fixing plate 22, a locking screw 23 threadedly connected to the threaded hole, the lower end of the locking screw 23 rotatably connected to the pressure plate 21, guide rods 24 on both sides of the pressure plate 21, a guide hole 25 on the fixing plate 22 for the guide rods 24 to pass through, a limit plate 26 fixedly connected after the guide rods 24 pass through the guide hole 25, and a plurality of evenly spaced slots 27 for the pressure plate 21 to engage. Rotating the locking screw 23 causes the pressure plate 21 to descend and engage in the slots 27, thereby fixing the adjusting rod 6. When the adjusting rod 6 needs to be manually changed, the locking screw 23 is rotated in the opposite direction, causing the pressure plate 21 to rise and the adjusting rod 6 to unlock. The adjusting rod 6 can be pulled radially by the handle 20 to manually control the position of the plug 3.

[0023] Furthermore, a liquid receiving tank 28 is fixedly connected to the aluminum liquid insulation tank 1. After the aluminum liquid flows out from the aluminum liquid outlet hole 2, it enters the liquid receiving tank 28. A liquid level sensor is installed in the liquid receiving tank 28. The liquid level sensor senses and provides feedback on the liquid level of the aluminum liquid in the liquid receiving tank 28 in real time. The forward and backward movement drive mechanism and the left and right movement drive mechanism can be activated according to the signal fed back by the liquid level sensor, thereby adjusting the plug 3 and changing the flow rate of the aluminum liquid in the aluminum liquid outlet hole 2.

[0024] Furthermore, aluminum liquid guide plates 29 are respectively provided on both sides of the aluminum liquid outflow hole 2, and the aluminum liquid guide plates 29 are provided with guide surfaces 30. The aluminum liquid guide plates 29 are respectively fixedly connected to the receiving tank 28. The aluminum liquid guide plates 29 guide all the aluminum liquid flowing out of the aluminum liquid outflow hole 2 into the receiving tank 28, reducing aluminum liquid splashing.

[0025] The automatic control method for molten aluminum includes the following steps: When it is necessary to completely block the molten aluminum outlet hole 2, a forward and backward movement drive mechanism drives the plug 3 forward, so that the top of the plug 3 is inserted into the molten aluminum outlet hole 2. At the same time, a left and right movement drive mechanism drives the plug 3 to move back and forth left and right, so that the plug 3 completely blocks the molten aluminum outlet hole 2. When it is necessary to completely open the molten aluminum outlet hole 2 to allow molten aluminum to flow out at maximum flow rate, the forward and backward movement drive mechanism drives the plug 3 backward, so that the plug 3 is completely removed from the molten aluminum outlet hole 2. When it is necessary to control the flow rate of molten aluminum in the molten aluminum outlet hole 2, the forward and backward movement drive mechanism and the left and right movement drive mechanism drive the plug 3 to move, so that the plug 3 is partially in the molten aluminum outlet hole 2. The position and angle of the plug 3 are controlled, thereby controlling the flow rate of molten aluminum. The forward and backward movement drive mechanism drives the plug 3 to move back and forth, realizing the axial displacement change of the plug 3 and controlling the position of the plug 3. The left-right movement drive mechanism moves the plug 3 left and right, allowing for better alignment and complete blockage of the aluminum molten outlet hole 2 during the blocking process. If the plug 3 does not completely block the outlet hole 2 and some aluminum molten material leaks out, the left-right movement drive mechanism can be used to change the flow rate and control the amount of aluminum molten material flowing out.
