Description

TECHNICAL FIELD

[0001] The utility model relates to an aluminium liquid lifting and conveying device and belongs to the technical field of smelting furnace equipment. BACKGROUND

[0002] In the production of aluminium alloy smelting, it is a key link to lift and convey aluminium liquid in a molten state from one position to another. In order to reduce raw material cost, the current equipment generally adopts an aluminium scrap compatible smelting furnace. In actual production, aluminium ingots need to be put into the melting chamber of the furnace, the aluminium ingots need to be heated and melted, the aluminium water needs to be flowed into the holding chamber, the aluminium scrap needs to be put into the vortex chamber, and the molten aluminium needs to be flowed into the holding chamber. After the aluminium water in the holding chamber is qualified, the aluminium water needs to be flowed into the static furnace, and the water needs to be discharged from the static furnace to the tundish and then transferred to the casting process. After searching, it is found that a Chinese patent with the publication number CN212931018U discloses an automatic water discharging structure of a smelting furnace or a holding furnace. In the patent, the plug is blocked at the discharge end of the aluminium liquid outflow channel. When it is needed to discharge the aluminium liquid, the piston rod of the air cylinder is elongated, the plug is lifted upward through the connecting piece and the connecting rod, the connecting rod and the plug slide upward along the rolling guide rail, the plug is moved away from the discharge end of the aluminium liquid outflow channel, and the aluminium liquid flows out of the smelting furnace or the holding furnace through the outflow channel and the flow groove. When it is needed to stop the aluminium liquid from flowing out, the piston rod of the air cylinder is shortened, the connecting rod and the plug move downward, and the plug is blocked again at the discharge end of the outflow channel to stop the aluminium liquid from flowing out. However, in the patent, the plug is prone to splashing during the plug pulling process, which may cause safety hazards. Frequent plug pulling may cause wear of the plug, which needs to be replaced frequently, thereby increasing production cost. SUMMARY
