TECHNICAL FIELD

[0001] The utility model relates to metal scrap recovery technical field, concretely relates to a kind of liquid metal flow guide groove for tilting rotary kiln. BACKGROUND

[0002] Rotary kiln (rotary furnace) is widely applied to melt processing various metal scrap, the equipment is uniformly heated to internal material by continuous rotation, so that the metal scrap filled in furnace body is gradually melted into liquid metal, wherein since tilting rotary kiln (inclined rotary kiln) can be inclined to a certain angle, not only can the inclination angle be adjusted according to production needs to adapt to the heating needs of different metal scrap, but also can make loading and unloading more easily, so it has been widely applied in actual production.

[0003] In the prior art, the tilting rotary kiln often uses a flow guide groove to guide the flow of liquid metal during pouring. However, the existing flow guide groove structure is usually fixedly arranged at the discharge port of the tilting rotary kiln. For tilting rotary kilns that share a furnace opening for both charging and discharging (such as the rotary kiln in the patent with publication number CN211695826U), the fixed flow guide groove structure often affects the charging of the rotary kiln.
