[0021] (2) A simple-to-operate metal powder processing feeding device and method. When the device is drying the interior, the vacuum pump is started by an external controller.

The pressure tank is filled with water. When the bottom of the conveying mechanism and the inside of the discharge mechanism of the device need to be cleaned, the control valve is opened so that the pressure inside the pressure tank pushes the water inside the pressure tank into the drain pipe, and then into the nozzle through the drain pipe. The water outlet distributed in the ring shape of the nozzle can make the water flow downward along the inner wall of the discharge bin to clean the inner wall, which is beneficial to improve the energy utilization rate of the vacuum pump, so that the device can pump water into the nozzle to clean the inside of the device without the help of external booster equipment, thereby achieving a better auxiliary cleaning effect.
