Description

Technical Field

[0001] The utility model relates to the technical field of liquid level detection, in particular to a molten aluminum liquid level detection device. Background Art

[0002] At present, after smelting, molten aluminum flows from the front box into the aluminum tank, and then passes through the aluminum tank to the rolling mill for production. During the production process of the rolling mill, the liquid level of the aluminum liquid needs to be controlled at a certain liquid level. The existing technology uses a flow-limiting structure to control the outflowing aluminum liquid to a certain extent. For example, the flow control is achieved by controlling the lifting of a floating plate to control the conical plug to seal the aluminum outlet to ensure that the height of the aluminum liquid is maintained at a certain liquid level. Although this method is effective, it often reacts slowly and the reminder is not timely. In current technology, there is also a consideration of using electronic components to monitor the liquid level of the aluminum liquid in the aluminum tank, but due to the high temperature of the aluminum liquid, the installation of electronic components will be difficult.

[0029] Example

[0030] like Figure 1 , 2As shown in Figures 3 and 5, a molten aluminum level detection device comprises a front box 1, an aluminum tank 102 and a detection component. A liquid outlet 101 is provided at one end of the front box 1, and the aluminum tank 102 is arranged opposite to the liquid outlet 101. The detection component is arranged on both sides of the aluminum tank 102. The detection component comprises a support frame 2 and a current limiting structure 7. The support frame 2 comprises a top plate 21, a telescopic rod I 22 and a telescopic rod II 23. The telescopic rod I 22 and the telescopic rod II 23 are arranged at the lower end of the top plate 21. A detection component 3 is arranged on the top plate 21. The detection component 3 is a laser level meter. The support frame 2 is installed on the outside of the aluminum tank 102. The position of the top plate 21 can be adjusted by adjusting the telescopic rod I 22 and the telescopic rod II 23, so that the laser level meter is away from the high-temperature aluminum water. At the same time, it can ensure that the laser level meter can work normally and vertically monitor the aluminum water level in the aluminum tank 102.

[0031] like Figure 1-7 As shown, a connecting plate 4 is provided on the support frame 2, and the connecting plate 4 is arranged between the telescopic rod Ⅰ22 and the telescopic rod Ⅱ23. The two ends of the connecting plate 4 are respectively threadedly connected with the support rod 6.

The support rod 6 passes through the threaded hole and is threadedly connected with the threaded hole. A support plate 5 is provided at the bottom end of the support rod 6. The bottoms of the two support rods 6 are respectively rotatably connected with the support plate 5. A connecting groove 53 is provided on the support plate 5, and a limiting groove 54 is provided in the connecting groove 53. A retaining ring 62 is provided on the support rod 6. The support rod 6 and the retaining ring 62 extend into the connecting groove 53 and the retaining ring 62 is connected to the limiting groove 54. The support rod 6 can rotate in the connecting groove 53, and the limiting groove 54 limits its position to prevent the support rod 6 from detaching from the connecting groove 53.
