Homogenizing device of nuclear graphite powder for high temperature gas cooled reactor fuel element

Abstract

The invention relates to a homogenizing device of nuclear graphite powder for a high temperature gas cooled reactor fuel element. The homogenizing device comprises a material bearing barrel, an internal circulating mechanism and an external circulating mechanism, wherein the upper end of the material bearing barrel is sealed; the internal circulating mechanism is arranged above the material bearing barrel, and comprises a furnace body, a mixing device which is arranged in the central part of the furnace body and a dust removal assembly which is arranged above the furnace body and is eccentrically arranged; a material outlet pipe is arranged under the furnace body in a communicating way; the material outlet pipe penetrates through the upper surface of the material bearing barrel and is communicated with the inner part of the material bearing barrel; the external circulating mechanism is arranged at the outer side of the internal circulating mechanism, and comprises an outer pipeline; one end of the outer pipeline is communicated with the furnace body through a flange, and the other end of the outer pipeline penetrates through the upper surface of the material bearing barrel and is communicated with the inner part of the material bearing barrel; the flange is eccentrically arranged on the upper surface of the furnace body. According to the homogenizing device disclosed by the invention, the technical problem that a dead angle which cannot be stirred exists during homogenizing is solved.

Description
