Abstract
The invention provides a raw materials feeding apparatus capable of uniformly dispersing and feeding into a furnace agglomerated raw materials that are likely to undergo dusting, deformation and mutual adhesion. In a raw material feeding apparatus for a rotary hearth furnace, for feeding raw materials to a rotary hearth furnace by using a flat belt conveyor, the invention employs a construction in which a scraper for guiding the raw materials on the flat belt conveyor to a side surface of the flat belt conveyor is arranged obliquely to a traveling direction of the flat belt conveyor. Preferably, the scraper is arranged in such a manner as to guide the raw materials to both sides of the flat belt conveyor.
Claims6
A raw material-feeding apparatus for a rotary hearth furnace, for feeding raw materials to a rotary hearth furnace by using a flat belt conveyor, characterized in that a scraper for guiding the raw materials on said flat belt conveyor to a side edge of said flat belt conveyor is arranged obliquely to a traveling direction of said flat belt conveyor, wherein the raw materials on said flat bed conveyor are fed to the rotary hearth furnace from the side edge of said flat belt conveyor, and wherein a cutoff plate is arranged downward from the carrier surface of the flat belt conveyor and adjustment projections are disposed on the surface of the scraper on which the raw materials flow.
