AI Technical Summary
Technical Problem
The metal powder produced by existing plasma atomization methods is not fine enough because the contact time between the molten metal and the plasma jet is extremely short.
Method used
A preheating plasma atomization device is used. The metal raw material is heated to a molten state by setting a hot pool in the reactor body, and then the inert gas is mixed with the molten metal and then comes into contact with the plasma jet to achieve uniform dispersion and atomization.
Benefits of technology
Fine and uniform metal powder particles were obtained, which improved the powder dispersion effect.

Abstract
The application discloses a preheating type plasma atomization device, which comprises a reaction furnace body, a plasma generator, a melting mechanism and a discharging mechanism. The reaction furnace body is divided into an upper reaction chamber and a lower reaction chamber by a transverse plate. The plasma generator comprises a first electrode fixedly installed in the lower reaction chamber and a second electrode pivotally movable in the lower reaction chamber through a movable mechanism. The first electrode and the second electrode can generate plasma jet. The melting mechanism comprises a heat pool in the upper reaction chamber. A heating device is arranged in the heat pool and used for heating and melting the entering metal material. The discharging mechanism comprises a plurality of discharging pipes connected with the heat pool and a partition pipe covering the plurality of discharging pipes. A plurality of conduits are arranged in the partition pipe. The partition pipe and the plurality of conduits form a main gas channel. The discharging pipes and the corresponding conduits form branch gas channels. The application can melt the metal through preheating, mix the metal with inert gas and then perform plasma atomization, so that fine and uniform metal powder particles can be obtained.
