Embodiment Construction

[0045] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0046] The multi-stage vibratory shape sorting device provided by the present invention is used for the sorting of spherical nuclear fuel particles. For fuels with a special structure such as spherical nuclear fuel, it is impossible to divert the sorting equipment in the ordinary civil industry field. If the difference is too large, the accuracy requirements and anti-vibration requirements to be achieved are far from each other, and...

Abstract

The invention discloses a multi-stage vibration type shape sorting device for spherical nuclear fuel particles. The multi-stage vibration type shape sorting device comprises a feeding mechanism, a vibration transmission mechanism, an inclination angle adjustor, a material receiving box and an interstage particle conveying pipe. The feeding mechanism comprises a first-stage feeding mechanism and a second-stage feeding mechanism; the vibration transmission mechanism comprises a first-stage vibration table and a second-stage vibration table; the inclination angle adjustor comprises a first-stage inclination angle adjustor and a second-stage inclination angle adjustor, and the material receiving box comprises a first-stage qualified material receiving box, a first-stage waste material receiving box and an interstage particle conveying receiving box which are arranged on the discharging side of the first-stage vibration table and communicated with the vibration table surface of the first-stage vibration table; the material receiving box further comprises a second-stage qualified material receiving box and a second-stage waste material receiving box which are arranged on the discharging side of the second-stage vibration table and communicated with the vibration table surface of the second-stage vibration table. One end of the interstage particle conveying pipe communicates with the interstage particle conveying receiving box, and the other end of the interstage particle conveying pipe communicates with the second-stage feeding mechanism. Therefore, the technical problems of low particle screening precision and poor equipment vibration uniformity are solved.

Description

technical field [0001] The invention relates to the technical field of nuclear fuel particle separation, in particular to a multi-stage vibratory shape separation device for spherical nuclear fuel particles. Background technique [0002] In the field of nuclear reaction, the spherical fuel element used in the pebble bed high temperature gas-cooled reactor has spherical ceramic coated particles (TRISO) dispersed in the graphite matrix in the fuel area. Spherical fuel elements are an important guarantee for the inherent safety of high-temperature gas-cooled reactor nuclear power plants. The TRISO-type coated fuel particles used in them are the first barrier to prevent the release of fission products during normal operation and even accidental conditions. The coated fuel particles are composed of a spherical nuclear fuel UO2 core, a loose pyrolytic carbon layer, an inner dense pyrolytic carbon layer, a silicon carbide layer and an outer dense pyrolytic carbon layer. A layer of...
