A plurality of partition plates 303 are vertically arranged inside the box 301, which can divide the inside of the collection box 301 into a plurality of spaces for storing materials. A connecting member 305 is arranged between the left side of the lower end of the smelting hanging basket 401 and the inner wall of the steel structure cover 402. The smelting hanging basket 401 and the steel structure cover 402 are connected only by a connecting member 305, which is convenient for the subsequent tilting of the smelting hanging basket 401 to one side, so that the materials inside the smelting hanging basket 401 can be discharged downward. The connecting member 305 includes a mounting A third motor box 3053 is mounted on the outer surface of the steel structure cover 402, and a winding wheel 3054 is provided at the rear end of the third motor box 3053. A guide wheel 3052 is provided on the inner wall of the steel structure cover 402 to guide the connecting steel cable 3051. A connecting steel cable 3051 is provided on the side of the lower end of the smelting basket 401. The connecting steel cable 3051 bypasses the guide wheel 3052 and passes through the steel structure cover 402 and is wound around the winding wheel 3054, so as to be used for lifting and lowering the smelting basket 401.

A blocking member 500 is provided in the discharge port. The discharge port is blocked by the blocking member 500, and the subsequent discharge of materials from the discharge port is not affected. The blocking member 500 includes a fixed lug 501 fixed to the inner wall of the discharge port, and a rotating baffle plate 502 for filling the discharge port is rotatably sleeved on the outer side of the fixed lug 501, and the rotating connection is convenient for the rotation of the rotating baffle plate 502.

Therefore, the rotating baffle plate 502 exposes the discharge port, and the materials retained on each layer of the multi-stage filter plate 4081 are discharged downward along the discharge port and fall into the collection box 301. In combination with the material-pickling component 408, the materials retained on the multi-stage filter plate 4081 are conveniently discharged, and the smelted metal liquid falls into the collection box 301 and enters the mold through the outlet for forming. In this process, the outer surface of the collection box 301 can be provided with The electric heating device keeps the collecting box 301 heated at all times without affecting the flow of the molten metal into the mold. After the material is discharged, the hanging steel cable 404 is wound upward, the smelting basket 401 is in a vertical position, and the rotating baffle plate 502 fills the discharge port again. In the absence of external force, the rotating baffle plate 502 is not likely to expose the discharge port. The entire separation and smelting mechanism 400 can then be moved to the smelting furnace body 100 for reuse. The entire process increases the convenience of smelting material discharge and ensures that the molten metal is clean and not easily mixed with impurities.
