Abstract
The online monitoring device comprises a furnace body, a monitoring opening is formed in the upper surface of the furnace body, a sleeve is fixedly connected to the upper portion of the monitoring opening, a telescopic pipe is fixedly connected to the upper end of the sleeve, a rotating disc is arranged above the telescopic pipe, an annular groove is formed in the lower surface of the rotating disc, and the upper end of the annular groove is fixedly connected with the upper end of the sleeve. A through hole is formed in the rotating disc and located in the inner side of the annular groove, a laser range finder is fixedly installed in the through hole, a driving assembly is arranged on the side surface of the rotating disc, a supporting shaft is rotationally connected to the lower surface of the rotating disc, and a connecting piece is fixedly connected to the lower end of the supporting shaft; one end of the connecting piece is fixedly connected with a bottom plate, and a lifting assembly is arranged on the lower surface of the bottom plate. The problem that temperature loss in the smelting furnace is easily caused when the liquid level of the molten aluminum in the furnace is monitored traditionally is solved, the situation that the molten aluminum is partially solidified when the liquid level of the molten aluminum in the furnace is monitored is avoided, and therefore the accuracy of liquid level measurement of the molten aluminum in the furnace is improved.
