1. smelting apparatus;

  • Comprise that smelting furnace with housing and solid inject jet pipe, this housing surrounds the internal space of stove, and this solid injects that jet pipe extends through the opening of furnace shell and the internal space that gets into stove;

    Said solid injects jet pipe and comprises central core tube and shell-cooling annulus;

    Through central core tube solid particulate materials is sent in the stove, shell-cooling annulus on most of length of central core tube around central core tube and be provided with the but water flow inside passage used of water flows of cooling, wherein;

    Solid injects jet pipe and further comprises the toroidal nozzle installation parts;

    This toroidal nozzle installation parts extends at the position spaced place at the front end with jet pipe around shell-cooling annulus backward, thereby forms the jet pipe sections that partly has the increased cross-section size than the jet pipe that extends forward thus in this position, and the housing of this stove is provided with from this fender around the outward extending jet pipe mounting pipe of said opening;

    And the jet pipe installation parts is accommodated in the mounting pipe and extends into or pass the opening in the housing;

    Wherein, said smelting apparatus further comprises releasable securing gear, is used for jet pipe is fastened to the jet pipe installation parts;

    Releasable securing gear is such;

    when being released, jet pipe through its installation parts in mounting pipe slip and can be driven in furnace interior and move a segment distance.
