One end of the air inlet pipe 16 penetrates through one side of the transfer package outer shell steel structure 1 and is located inside the transfer package outer shell steel structure 1, and the other end of the air inlet pipe 16 penetrates through one side of the air source control cabinet 18 and is located outside the air source control cabinet 18; a filter pressure reducing valve 21 is provided on the side of the air inlet pipe 16 away from the air outlet pipe 17, a pilot-operated normally closed fluid control valve 23 is provided in the middle of the air inlet pipe 16, and a pressure sensor 24 is provided on the side of the air inlet pipe 16 close to the air outlet pipe 17.
[0029] Specifically, through the operation of the vacuum conveyor 27 and the electric ball valve 22, negative pressure soup suction can be carried out inside the lining and thermal insulation material 19 through the air outlet pipe 17 according to requirements. Through the setting of the pressure sensor 24, the pressure inside the lining and thermal insulation material 19 is monitored. Through the operation of the filter pressure reducing valve 21 and the pilot-operated normally closed fluid control valve 23, pressure soup feeding can be carried out inside the lining and thermal insulation material 19 through the air inlet pipe 16 according to requirements, so as to carry out negative pressure soup suction or pressure soup feeding on the molten aluminum inside the lining and thermal insulation material 19, thereby realizing the transportation of molten aluminum and improving the safety of molten aluminum transportation.
[0030] Working principle: During use, the AGV moves the transfer package to the ladling opening of the melting furnace through the forklift arm sleeve 2, and then lowers the transfer package to the liquid level height detected by the positioning detection electrode 12 according to requirements, so that the end riser 11 is in the corresponding molten aluminum. Then, the electric ball valve 22 and the vacuum conveyor 27 are opened to reduce the pressure inside the inner lining and the thermal insulation material 19, so that the molten aluminum at the ladling opening of the melting furnace is transported to the inside of the inner lining and the thermal insulation material 19 through the end riser 11, the elbow after the riser 10, the middle riser 9, the elbow before the riser 8, and the front riser 20. The pressure inside the inner lining and the thermal insulation material 19 is detected in real time by the pressure sensor 24, and the liquid level height of the molten aluminum inside the inner lining and the thermal insulation material 19 is detected by the laser level sensor 15. When the molten aluminum reaches the corresponding liquid level, the electric ball valve 22 and the vacuum conveyor 27 are closed, and then the AGV raises the transfer package to disengage the end riser 11 from the ladling opening, and then moves to the molten aluminum insulation chamber of the holding furnace. Then, the vacuum conveyor 27 is opened to increase the pressure inside the inner lining and the thermal insulation material 19, so that the molten aluminum inside it enters the insulation chamber through the front riser 20, the elbow before the riser 8, the middle riser 9, the elbow after the riser 10, and the end riser 11 according to requirements, thus completing the transfer of the molten aluminum.
