Beschreibung
Zusammenfassung:	The invention relates to a laser cladding boiling type powder feeder which comprises a powder storage tank, a powder feeding pipe, an upper boiling cavity and a lower boiling cavity. The powder feeding pipe penetrates through a cavity of the upper boiling cavity, and an air inlet pipe communicating with the cavity of the lower boiling cavity is arranged on the lower boiling cavity. A compact screen is arranged between cavities of the upper boiling cavity and the lower boiling cavity. The powder storage tank is provided with an air inlet pipe communicating with a tank cavity of the powder storage tank, and a pipe body of the air inlet pipe is provided with a heating device capable of heating gas flowing through a pipe cavity. The heating device capable of heating gas flowing through the pipe cavity is arranged on the pipe body of the gas inlet pipe arranged on the lower boiling cavity. According to the laser cladding boiling type powder feeder, the purposes of improving the powder dryness and improving the pow
