Description

Technical Field

[0001] This utility model relates to the field of metal powder recycling technology, specifically to a pre-treatment device for metal powder recycling. Background Technology

[0002] Metal powders, especially rare and precious metal powders, have extremely high value in industrial production. With the increasing depletion of resources and the growing awareness of environmental protection, the recycling and reuse of metal powders has become an important issue. Through recycling, we can not only save raw materials and reduce production costs, but also reduce environmental pollution and achieve sustainable use of resources.

[0003] An existing Chinese patent (publication number: CN221515174U) discloses a metal powder processing device, including a sorting component and a collecting component. The sorting component includes a screw barrel shell and a screening component. The bottom end of the screw barrel shell is open, and a feeding cylinder is fixedly fixed through one side of the top surface of the screw barrel shell. The screening component includes a rotating shaft and a threaded cylinder. The rotating shaft is vertically rotatably connected inside the screw barrel shell, and the top of the rotating shaft is rotatably connected to the top surface of the screw barrel shell. A motor is vertically fixed on the top surface of the screw barrel shell, and the output end of the motor is fixed to the top surface of the rotating shaft. The threaded cylinder is threadedly assembled on... The screw barrel shell has a mesh fixed to the bottom surface of the screw barrel. This overcomes the problem that when alloy powder is added to a vibrating screen for sieving, the vibrating screen only has a single layer of screening mesh, which means that the alloy powder can only be sieved for a single particle size. This results in incomplete sieving of the alloy powder, and the presence of impurities and particles of different sizes inside affects the fineness of the alloy powder in subsequent processing. In the above patent, the non-magnetic metal powder and magnetic metal powder in the metal powder are mixed together, making it difficult to separate the non-magnetic metal powder and magnetic metal powder, resulting in the waste of some valuable metal powder.
