Abstract
An apparatus for distributing materials into a blast furnace using no bell. The apparatus has a material distributing hopper disposed for a rocking motion around the central axis of said furnace. The rocking motion of the material distributing hopper is caused by an axial movement and rotation of a single drive shaft disposed outside the furnace.
Claims7
An apparatus for distributing materials into a vertical type furnace comprising:
- a ring-shaped frame supported in a furnace top casing through which the material throw-in duct passes, said frame being mounted for rocking in one direction;
- a material distributing hopper supported by said frame for rocking in a direction perpendicular to the direction of rocking of said frame;
- a vertical drive shaft connected to a driving source outside said furnace and extending through said casing, said drive shaft being mounted rotatably and movably in the axial direction;
- and means connecting said drive shaft to said material distributing hopper for translating selected rotary and axial movment of said drive shaft into corresponding movement of said hopper.
