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

technical field [0001] The invention relates to the technical field of graphite manufacture, in particular to a homogenizing device for nuclear graphite powder used in high-temperature gas-cooled reactor nuclear fuel elements.

[0003] The patent No. is that the patent document of CN205462250U discloses a kind of improved graphite powder reactor, comprises graphite powder reactor body, and the side wall thickness H of graphite powder reactor body is 12mm, and the bottom of graphite powder reactor body is provided with a plane bottom plate, The middle part of the flat bottom plate is provided with a discharge port...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to address the deficiencies of the prior art, by setting the internal circulation mechanism to cooperate with the external circulation mechanism, so that during the homogenization operation, in addition to the homogenization effect of the internal mixing component, the material passes through the external pipeline from the furnace outlet It enters the furnace body to realize the external large circulation, and then solves the dead angle of stirring. At the same time, materials with different specific gravity can be fully mixed, thus solving the dead angle that cannot be stirred during homogenization, and when homogenizing materials with different weights, light Materials are easy to float on the upper layer, resulting in technical problems of segregation
