Abstract
A rotatable and angularly adjustable charging and distribution device for shaft furnaces, particularly blast furnaces, is presented. A cylindrical or frustoconical distribution spout is suspended at three points which define a plane. The three points of suspension are caused to move longitudinally (i.e. substantially vertically) and synchronously whereby the lateral surface of the distribution spout may be caused to move in a path which is virtually conical without rotating the suspension points about the vertical axis of the furnace. The suspension points may be moved either by delivering a driving force to them or by applying a traction force to them.
Claims37
Apparatus for charging a shaft furnace including:
- tubular distribution means mounted in said furnace for distributing charge material to said furnace, said distribution means having an axis and oppositely disposed inlet and discharge ends;
- guide means in said furnace for supporting said distribution means adjacent its inlet end for movement, said guide means permitting angular and rotary adjustment of the axis of said distribution means with respect to an axis of said furnace;
- at least three control elements connected to said distribution means at spatially displaced points;
- actuating means for longitudinally moving said control elements to direct the discharge of said distribution means to selected positions in said furnace;
- and
- control means for independently regulating said actuating means in synchronism.
Apparatus for charging a shaft furnace has an intake chute for delivery of charge material to said distribution means;
- said intake chute and said distribution means each having an axis, said axes intersecting at a point;
- said
- the center of the spherical surface defined by said guide means is at said point of intersection of said axes of said distribution means and said intake chute.
Apparatus for charging a shaft furnace as in claim 33 wherein said adjustment means includes:
- follower means connected to and extending from said outer ring;
- second motor means;
- and
- means connecting said second motor means to act on said follower means to angularly adjust the position of said bearing means.
Apparatus for charging a shaft furnace including:
- tubular distribution means mounted in said furnace for distributing charge material to said furnace, said distribution means having an axis and inlet and discharge ends;
- guide means in said furnace for supporting said distribution means for movement, said guide means permitting angular and rotary adjustment of the axis of said distribution means with respect to an axis of said furnace;
- at least three control elements connected to said distribution means at spatially displaced points;
- and
- at least three hydraulic jacks positioned outside of the furnace and spaced equidistantly apart about said furnace, one each of said hydraulic jacks being connected to one of said control elements for longitudinally and synchronously moving said control elements to direct the discharge of said distribution means to selected positions in said furnace.
