Problems solved by technology

[0004] The production efficiency of a single equipment in this process is 80 pieces / hour, with many process steps and complex equipment structure, and due to the open and multiple transfer of powder materials, there is a certain gap between the quality of the final matrix graphite powder and the set quality. The difference reduces the accuracy of the addition

Abstract

The invention relates to the field of equipment, in particular to a device and a method for simultaneously metering and mixing two or more materials, and more particularly relates to metering and uniform mixing of two materials, namely matrix graphite powder and dressing particles, when the two materials are fed into a material tank. According to the device for simultaneously metering and mixing two or more materials, quantitative mixing of the materials can be completed through the arrangement of a scraper blade, a quantifying cup and a material discharging control device in a material quantifying device and the arrangement of a mixing screen and a charging container in a mixing device, the process is automatically completed, the technological process is simple, and the production efficiency is high. According to the device and the method for simultaneously metering and mixing two or more materials, the production process of quantitative powder adding, particle adding and mixing performed in a fuel area is successfully simplified, the production efficiency is improved under the condition of meeting the element design requirement, and the requirement of large-scale production of spherical fuel elements is met.

Description

technical field [0001] The present invention relates to the field of equipment, in particular to a device and method for realizing the simultaneous metering and mixing of two or more materials, and more specifically to the realization of metering and uniformity of the two materials, matrix graphite powder and dressing particles, while feeding into a material tank. mix. Background technique [0002] The pebble bed high-temperature gas-cooled reactor is one of the most advanced nuclear reactors in the world. The fuel used in this reactor type is a spherical fuel element. It is prepared by preforming the fuel region, pressing the ball blank, low-temperature carbonization, turning (or turning, low-temperature carbonization) and high-temperature purification. In the preforming process of the fuel zone, the quantitative addition and uniform mixing process of the matrix graphite powder and the dressing particles are important factors affecting the production efficiency of the fuel...
