Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum liquid flow control technology, and in particular to an aluminum liquid output switch control device. Background Technology
[0002] After passing through a degassing and filtration device, molten aluminum flows into a casting sand box for casting. The castings are ingots or plates, etc. To reduce casting defects, it is required that the liquid level in the casting sand box change little. The traditional method is to use components such as a ladle, a tilting cylinder, a laser level gauge, and a PLC controller to coordinate the casting process. The control of the liquid level in the sand box relies on the extension and retraction of the tilting cylinder. However, since the cylinder drives the ladle to tilt, it is difficult to fine-tune the flow rate of molten aluminum. Once the extension and retraction of the cylinder changes, the molten aluminum flows into the sand box according to an exponential change, resulting in large changes in the liquid level in the sand box. Therefore, there is an urgent need for a molten aluminum output switch control device that can achieve fine-tuning of the flow rate. Utility Model Content
[0003] The purpose of this invention is to provide an aluminum liquid output switch control device to solve the problem that when the ladle is turned over by the oil cylinder, the aluminum liquid flows into the sand box according to the exponential change, resulting in large changes in the liquid level in the sand box, which affects the casting quality.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] An aluminum liquid output switch control device includes an aluminum liquid tank with an outlet hole. A switch control device adapted to the outlet hole is installed at the aluminum liquid tank. The switch control device includes a telescopic cylinder, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, and a plug. One end of the telescopic cylinder, one end of the first connecting rod, one end of the second connecting rod, and one end of the third connecting rod are rotatably connected to the outer wall of the aluminum liquid tank. The other end of the third connecting rod and one end of the fourth connecting rod are rotatably connected to the power output end of the telescopic cylinder. The other end of the fourth connecting rod is slidably connected to the second connecting rod. The other ends of the first connecting rod and the other ends of the second connecting rod are rotatably connected to the plug. The working end of the plug faces the outlet hole.
[0006] A further technical solution is: the plugging device includes a horizontal plate, a drill rod, and a plug. The horizontal plate is rotatably connected to the first connecting rod and the second connecting rod. The drill rod is mounted on the horizontal plate, and the plug is mounted on the outer end of the drill rod.
[0007] A further technical solution is that the drill rod is Z-shaped, and the drill rod and the cross plate are rotatably connected by a torsion spring.
[0008] A further technical solution is that the plug is conical.
[0009] A further technical solution is that the liquid outlet is funnel-shaped, with the larger diameter end facing outwards.

[0023] Example 1:
[0024] This implementation example Figure 1 and Figure 2As shown, an aluminum liquid output switch control device includes an aluminum liquid tank 1 with an outlet hole 9. A switch control device 2 adapted to the outlet hole 9 is installed at the aluminum liquid tank 1. The switch control device 2 includes a telescopic cylinder 3, a first connecting rod 4, a second connecting rod 5, a third connecting rod 6, a fourth connecting rod 7, and a plug 8. One end of the telescopic cylinder 3, one end of the first connecting rod 4, one end of the second connecting rod 5, and one end of the third connecting rod 6 are all rotatably connected to the outer wall of the aluminum liquid tank 1. The other end of the third connecting rod 6 and one end of the fourth connecting rod 7 are rotatably connected to the power output end of the telescopic cylinder 3. The other end of the fourth connecting rod 7 is slidably connected to the second connecting rod 5. The other end of the first connecting rod 4 and the other end of the second connecting rod 5 are rotatably connected to the plug 8. The working end of the plug 8 faces the outlet hole 9.
[0025] When aluminum liquid is discharged from aluminum liquid tank 1, the telescopic cylinder (usually a hydraulic cylinder or electric push rod) is controlled to extend and retract according to the required aluminum liquid flow rate. When the telescopic cylinder 3 extends, it drives the third link 6 and the fourth link 7 to expand laterally, thereby driving the first link 4 and the second link 5 to move the bottom plug 8 towards the liquid outlet 9 until the plug 8 blocks the liquid outlet. When it is necessary to discharge the aluminum liquid, the telescopic cylinder 3 retracts, driving the third link 6 and the fourth link 7 to retract, thereby driving the first link 4 and the second link 5 to gradually move the bottom plug 8 away from the liquid outlet 9, thereby gradually increasing the flow rate of the liquid outlet 9.
[0026] Preferably, the plugging device 8 includes a horizontal plate 10, a drill rod 11, and a plug 12. The horizontal plate 10 is rotatably connected to the first connecting rod 4 and the second connecting rod 5. The drill rod 11 is mounted on the horizontal plate 10, and the plug 12 is mounted on the outer end of the drill rod 11.
[0027] The use of the drill rod 11 serves two purposes: firstly, it is resistant to high temperatures, and secondly, it keeps the switch control device 2, especially the telescopic cylinder 3, away from the high-temperature aluminum molten tank 1, ensuring the stable operation of electrical components and extending their service life.
[0028] Preferably, such as Figure 3 As shown, the drill rod 11 is Z-shaped, and the drill rod 11 is rotatably connected to the horizontal plate 10 through a torsion spring 13.
[0029] When the head of the drill rod 11 enters the liquid outlet hole 9, the liquid outlet hole 9 causes the drill rod 11 to rotate gradually, reducing interference and ensuring that the plug 12 can smoothly enter the liquid outlet hole 9.
[0030] Preferably, the plug 12 is conical.
[0031] The conical plug 12 is better suited to the liquid outlet 9.
[0032] Preferably, the liquid outlet 9 is funnel-shaped, with the larger diameter end facing outwards.
[0033] The funnel-shaped liquid outlet 9 allows the drill rod 11 to enter easily.
[0034] Preferably, the first link 4 and the second link 5 are of the same length and are parallel to each other.
[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
