Abstract
A laminated wide-band powder feeding nozzle with bilateral rectifying gases is disclosed. An inlet segment of a top plate extends upwards and slantwise, and is provided with an upper rectifying gas through hole, a powder through hole and a lower rectifying gas through hole. A first groove and an upper lamination below the first groove define an upper rectifying gas flow channel with one end communicating with the upper rectifying gas through hole and the other end extending to an outlet end of a nozzle body to form an upper rectifying gas outlet. The upper lamination and a lower lamination, together with a through groove therebetween, define a powder flow channel with one end communicating with the powder through hole and the other end extending to the outlet end of the nozzle body to form a powder outlet. A second groove and the lower lamination above the second groove define a lower rectifying gas flow channel with one end communicating with the lower rectifying gas through hole and the other end extending to the outlet end of the nozzle body to form a lower rectifying gas outlet. In addition, the upper rectifying gas outlet and the lower rectifying gas outlet are located above and below the powder outlet, respectively.
