Embodiment

[0037] Uranium dioxide core aging tank, the aging tank is a cylindrical body with an opening on the upper surface, and the opening is sealed with a sealing cover. The aging tank sealed with the sealing cover and the sealing cover form a complete aging tank. The upper surface of the groove is the sealing cover. The sealing cover has an air outlet, a spray interface, a heating device interface, and a vibrating device on the side surface of the aging tank. At the same time, a stirring device may be provided inside the aging tank.

[0038] The vibrating device may be any one of mechanical vibrating device, ultrasonic vibrating device or a combination of both. A mechanical stirring device can be installed inside the aging tank as required.

[0039] The aging tank belt can have its own heating device, and the heating device can be laid inside or outside the aging tank. The external heating device of the aging tank can be any combination of heating rods, heating sheets, and heatin...

Abstract

The invention discloses a uranium dioxide core aging tank. The aging tank is a cylindrical object with an opening on the surface, and the opening is sealed by a sealing cover; the surface of the aging tank is provided with a gas outlet, spray interfaces and heating device interfaces; the aging tank is provided with a vibration and/or stirring device. The invention discloses a system for aging, cleaning and drying uranium dioxide cores. The system includes aging tank modules each composed of the uranium dioxide core aging tank, an aging region module, a cleaning region module, a drying region module and a conveying module. At the same time, the invention also discloses a method for aging, cleaning and drying the uranium dioxide cores. The method comprises the steps: standing for aging the uranium dioxide cores by using the aging region module, conveying the aging tank modules to the cleaning region module by using the conveying module, cleaning the uranium dioxide cores by using the cleaning region module, conveying the aging tank modules to the drying region module by using the conveying module, and drying the uranium dioxide cores in the aging tank modules by using the drying region module.

Description

technical field [0001] The invention relates to the technical field of raw material aging, washing and drying equipment, in particular to a uranium dioxide core aging washing and drying system and method. Background technique [0002] The uranium dioxide core is an important part of the spherical fuel element of the high temperature gas-cooled reactor, and the mainstream process currently used is the sol-gel method. According to different gel principles, it can be divided into external gelation, internal gelation, and full gelation process combining internal and external. Various gelation processes generally go through the steps of sol preparation, dispersion gelation into balls, aging, washing, drying, roasting, and reduction sintering, wherein the aging, washing, and drying steps are located in the middle stages of the entire process. [0003] In traditional technology, the three process steps of aging, washing, and drying are independent processes, which need to be carri...
