[0019] See also Figure 1 and Figure 2 The present invention now provides an intelligent furnace liquid transfer system. The intelligent furnace liquid transfer system comprises an aluminum chip furnace 1, multiple holding furnaces 2, and an aluminum liquid launder 3. The aluminum liquid launder 3 is provided with multiple liquid inlet launders 4 spaced apart from each other, each of which is connected to the multiple holding furnaces 2. A liquid receiving hopper 5 is provided on the aluminum liquid launder 3. The aluminum chip furnace 1 is internally provided with an aluminum liquid holding chamber for holding the aluminum liquid. The aluminum chip furnace 1 is provided with a liquid outlet trough connected to the aluminum liquid holding chamber, which is connected to the liquid receiving hopper 5. A liquid level detection unit is installed on the top of the aluminum liquid holding chamber to detect the liquid level of the aluminum liquid in the aluminum liquid holding chamber.

[0020] The present invention provides an intelligent furnace liquid transfer system. Compared to existing technologies, a liquid level detection unit is installed at the top of the aluminum molten storage chamber of the aluminum chip furnace 1. After aluminum chips are melted, they form molten aluminum and are stored in the molten aluminum storage chamber. The liquid level detection unit detects the liquid level in the molten aluminum storage chamber and calculates the weight of the molten aluminum within the furnace 1 based on the shape of the molten aluminum storage chamber and its volume density. When the aluminum chip furnace 1 supplies molten aluminum to different holding furnaces 2, the molten aluminum flows through the liquid outlet trough into the molten aluminum flow trough 3 and then through multiple liquid inlet troughs 4 into different holding furnaces 2. As the molten aluminum in the aluminum chip furnace 1 continuously enters the holding furnaces 2, the liquid level within the furnace 1 continuously decreases. The liquid level detection unit monitors the changes in the molten aluminum level in real time and determines the weight of the molten aluminum, ensuring that the weight of the transferred molten aluminum meets production requirements. This intelligent furnace liquid transfer system achieves automatic liquid transfer and precise proportioning.

[0021] In some possible embodiments, a guide pipe 7 is provided at one end of the liquid outlet trough away from the aluminum liquid containing chamber, the upper end of the guide pipe 7 is connected to the liquid outlet trough, and the lower end of the guide pipe 7 extends into the liquid receiving hopper 5. The aluminum liquid flowing out of the aluminum chip furnace 1 enters the aluminum liquid flow trough 3 through the liquid outlet trough, the guide pipe 7 and the liquid receiving hopper 5, and finally flows into the insulation furnace 2.

[0022] Among them, the aluminum chip furnace 1 is provided with a top plate on the top, and a mounting hole is opened on the top plate. The liquid level detection unit is installed in the mounting hole. The lower end of the liquid level detection unit is the detection end. The detection end of the liquid level detection unit is located in the aluminum liquid containing chamber. The detection end is perpendicular to the liquid surface of the aluminum liquid. The distance between the liquid surface of the aluminum liquid and the detection end can be directly obtained. Then, the distance between the detection end and the bottom of the aluminum liquid containing chamber is subtracted from the above distance to obtain the depth of the aluminum liquid in the aluminum liquid containing chamber. Then, the volume of the aluminum liquid is calculated according to the cross-section of the aluminum liquid containing chamber, and finally the weight of the aluminum liquid is calculated by the volume density.

[0023] Specifically, the liquid level detection unit is a laser rangefinder 6 .

[0024] Preferably, each holding furnace 2 is connected to at least two liquid inlet chutes 4, which can speed up the flow of molten aluminum into the holding furnace 2 and reduce the heat loss of the molten aluminum during the transportation process.

[0025] In addition, the aluminum molten launder 3 is provided with a plurality of opening and closing mechanisms 8, each corresponding to a plurality of liquid inlet launders 4. The opening and closing mechanisms 8 are used to switch the corresponding liquid inlet launder 4 on and off with respect to the aluminum molten launder 3. The opening and closing mechanisms 8 can be any component capable of realizing an opening and closing function, such as a valve, a gate, or a plug rod. By opening or closing the corresponding opening and closing mechanism 8 in a targeted manner, the corresponding liquid inlet launder 4 and the aluminum molten launder 3 can be connected or disconnected, thereby controlling whether the holding furnace 2 is filled with liquid or the amount of liquid being filled.

[0026] Specifically, an aluminum chip filling chamber 9 is provided on one side of the aluminum chip furnace 1. The aluminum chip filling chamber 9 is connected to the aluminum liquid storage chamber, and a rotatable furnace door is provided on the aluminum chip filling chamber 9. The furnace door is opened to fill aluminum chips into the aluminum chip filling chamber 9. The furnace door is closed to heat the aluminum chips in the aluminum chip filling chamber 9, causing them to melt and form aluminum liquid, which then enters the aluminum liquid storage chamber.
