Abstract
An apparatus for distributing charged raw material into a furnace, wherein an armer rod having a distributing plate for the charged material is arranged on bearings to be slidable toward the furnace, and wherein a novel dust sealing mechanism and a cooling device are provided to reduce in size or to omit conventional accompanying facilities so that a compact distributing apparatus is realized.
Claims8
A raw material distributing apparatus for a furnace, comprising
- an armer rod slidable with respect to said furnace;
- a distributing plate for charged raw material secured at a front end of said rod;
- a casing for holding said rod;
- a sliding bearing comprising hard synthetic resin arranged on an inner wall of said casing between said casing and said rod;
- a non-metallic dust sealing mechanism disposed toward an end of said sliding bearing;
- means for supplying sealing gas to said dust sealing mechanism;
- and
- cooling means having part hereof disposed within said rod and toward a front end of said casing, to cool the interior of said rod, and an outer circumference of said front of said casing;
- wherein said sealing mechanism comprises a unit casing, a first oil seal, a second oil seal, a set of supports, said unit casing being independent of said casing holding said rod, said first oil seal being secured to said unit casing and contacting its lip end to the outer periphery of said rod, said second oil seal being secured at the front end directed toward the furnace of said unit casing and being packed with adiabatic material for spouting out the sealing gas from the lip pointed into said furnace, and said supports being of hard synthetic resin and secured to said unit casing.
