1. a no charging bell at furnace top of blast furnace feeding device (20), including:

  • for receiving the top of furnace chargeBatch can (1);

    Top baiting valve (2), is connected to the bottom on described top batch can (1);

    Batch can (4),It is connected to the lower section on described top baiting valve (2);

    Material flow gate (5), is connected to described batch can (4)Bottom;

    And distribution device (8), it is connected to the bottom of described material flow gate (5), its featureIt is,Baiting valve upper flange is set at the receiving opening of top baiting valve (2), at top batch can (1)Bottom arranges top batch can lower flange, passes through securing member between baiting valve upper flange and top batch can lower flangeIt is connected, it is achieved thereby that the receiving opening on described top baiting valve (2) is by waiting bore structure to connectIn the bottom on described top batch can (1), under the upper connecting portion of described receiving opening and top batch can (1)Connecting portion forms the bullet that can reduce height space;

    The receiving opening of described material flow gate (5) leads toThe bore structure such as cross and be connected to the bottom of described batch can (4), the upper connecting portion of described receiving opening and batch can(4) lower connecting portion forms the bullet that can reduce height space;

    Also include;

    for the upper sealing valve (3) sealed, be connected to described top baiting valve (2) and materialBetween tank (4);

    For seal lower sealing valve (6), be connected to described material flow gate (5) andBetween distribution device (8);

    The bottom of described material flow gate (5) and lower sealing valve (6) are by waiting bore structure to be connected to oneRising, wherein the bottom of material flow gate (5) extend in the casing of lower sealing valve (6), lower sealing valvePressure head (6a) be installed on the flange in the bottom of material flow gate (5), thus reduce stream regulationValve (5) and lower sealing valve (6) height space each other.
