US 4,243,351 A · Method of and apparatus for charging a furnace

Abstract

An apparatus and process for introducing and distributing a charge within a shaft furnace, the shaft furnace charging apparatus comprising an elongated charge distribution chute, the angle of which being adjustable in relation to the vertical axis of the furnace to allow for distribution of charge to desired areas within the furnace. The charge distribution chute includes a first end for accepting the charge and a second end for distributing the charge within the furnace. The first end of the chute is suspended from a supporting fork which is rotatable about its axis to provide for pivoting of the chute about a first axis when the support fork is rotated. The chute is suspended from the support fork to provide for pivoting of the chute about a second axis which is preferably perpendicular to the first axis. The direction of the chute within the furnace may be adjusted to provide for distribution of the charge to the desired area of the furnace.

In a shaft furnace, improved charge distribution apparatus comprising:

elongated distribution chute means;
support means for said chute means, said support means extending through the furnace wall at a single location and being rotatable about a first axis, said support means including a base portion and a pair of arms extending therefrom;
means pivotally coupling said chute means to said support means arms adjacent a first end of said chute means, said coupling means defining a second axis transverse to said first axis, said first and second axes intersecting at a point;
means for rotating said support means to pivot said chute means about said first axis;
and
drive means connected to said chute means for imparting motion to said chute means to cause said chute means to pivot about said coupling means defined second axis, said motion imparting means in part extending through the furnace wall at said single location.

In a shaft furnace, improved charge distribution apparatus comprising:

elongated distribution chute means, said chute means including a tubular member having a frustoconical charge receiving portion at the first end thereof;
support means for said chute means, said support means being rotatable about a first axis and including a base portion and a pair of arms extending therefrom into the furnace, said support means further comprising a saddle pivotally connected to said arms and having a generally conical shape terminating in a ring, the ring having an internal diameter less than the maximum diameter of the frustoconical chute means portion, said saddle engaging the exterior of said chute means frustoconical portion;
means for rotating said support means to pivot said chute means about said first axis;
and
means for imparting motion to said chute means to cause said chute means to pivot about a second axis defined by the pivot connection between said support means arms and saddle, said second axis being transverse to said first axis and intersecting said first axis at a point.
