The utility model relates to
nitrogen atomizing equipment for aluminum
powder production, which comprises an atomizing chamber, a
nitrogen atomizing
nozzle and a receiving hopper, and is technically characterized in that a motor is fixed at the top of the atomizing chamber, and a cone
pulley which is wide in top and narrow in bottom and is connected with the output end of the motor is arranged in the atomizing chamber; the center line of the
nitrogen atomizing
nozzle is parallel to the horizontal plane, a
nozzle opening points to the middle of the cone
pulley, the
vertical plane where the center line of the cone
pulley is located coincides with the
vertical plane where the center line of the nitrogen atomizing nozzle is located, a support is arranged on the side wall, opposite to the side wall where the nitrogen atomizing nozzle is located, in the atomizing chamber, and a
brush making contact with the cone pulley is arranged on the support. A dust overflowing opening is fixed to the top of the atomizing chamber, a
backflow pipe inclining downwards is arranged on the lower portion of the side wall of the atomizing chamber, the outer end of the
backflow pipe is communicated with the outer end of the dust overflowing opening through an external pipeline, a pressure reducing valve is arranged on the external pipeline, and a horizontal spiral conveyor communicated with the lower end of the material receiving hopper is fixed to the bottom of the atomizing chamber. According to the equipment, bonded
powder is cleaned in time, waste is avoided, and collection of the
powder is facilitated.
