Automatic continuous feeding device of metallurgical furnace

Abstract

An automatic continuous feeding device of a metallurgical furnace includes an outer barrel and a plurality of inner barrels. The outer barrel includes an accommodation space having an out-feed channel communicated to a reduction furnace. An out-feed gate is disposed on the out-feed channel of the outer barrel. The inner barrels utilized to receive a material are disposed in the accommodation space of the outer barrel. Each of the inner barrels includes an in-feed opening and an out-feed opening, wherein the in-feed opening passing through the outer barrel to communicate to an exterior is enclosed by an openable cover enclosing mechanism, and an inner-barrel lower cover is disposed on each of the out-feed openings. The accommodation space of the outer barrel can be kept at an environmental temperature and pressure equal to that of the reduction furnace, to perform multiple feeding operations in an environment with constant temperature and pressure.
