Configuration mechanism for radiation shield concrete slurry used for neutron research

Abstract

The invention relates to a configuration mechanism for radiation shield concrete slurry used for a neutron research. The configuration mechanism for the radiation shield concrete slurry used for the neutron research comprises a rack and a configuration cylinder. The upper part of the configuration cylinder is provided with a particle feed inlet, the middle part is provided with a water injection inlet and a cement feed inlet, and the lower part is provided with a configuration outlet, and the configuration outlet is connected with a delivery cylinder through a delivery control valve. A vertically-directed stirring motor is arranged below an upper cover of the configuration cylinder. The lower part of the stirring motor is connected with a stirring rotating block, and the side of the stirring rotating block is provided with evenly stirring blades, and a stirring pulling rod is arranged at the lower part of the stirring rotating block. A stirring lifting seat is connected with the lowerpart of the stirring pulling rod. A stirring rod inclined outwards and downwards is evenly arranged around the stirring lifting seat. The configuration mechanism can feed granular raw materials separately. And through the action of the stirring blades, the granular raw materials can evenly fall into the bottom of the configuration cylinder, and with the stirring rod designed at the bottom, the rawmaterials can be fully mixed and stirred with cement and water, so as to ensure that the granular raw materials in the prepared concrete slurry basically maintain uniform.

Description

technical field [0001] The invention relates to the field of radiation-proof material processing equipment used for neutron scientific research, in particular to a configuration mechanism for radiation-proof concrete slurry used for neutron research. Background technique [0002] Neutron science is a high-tech subject, which reflects the technological level of a country. Neutron science research includes many contents, such as neutron collision and fusion. Most of neutron science research is accompanied by radiation, so Radiation-proof materials will be used. Most of the existing neutron tests use special radiation-proof concrete for radiation protection. This radiation-proof concrete is added with various particles, such as copper particles, zinc particles and other heavy metal particles and sand particles. It is made by mixing specific cement, and the anti-radiation effect of the anti-radiation concrete is controlled by the content and uniformity of the distribution of the...

[0002] Neutron science is a high-tech subject, which reflects the technological level of a country. Neutron science research includes many contents, such as neutron collision and fusion. Most of neutron science research is accompanied by radiation, so Radiation-proof materials will be used. Most of the existing neutron tests use special radiation-proof concrete for radiation protection. This radiation-proof concrete is added with various particles, such as copper particles, zinc particles and other heavy metal particles and sand particles. It is made by mixing specific cement, and the anti-radiation effect of the anti-radiation concrete is controlled by the content and uniformity of the distribution of the particles. Most of the existing concrete slurry configurations use a mixer to add the materials at one time, and then It is stirred and mixed through the spiral stirring part, and there is a big defect in the configuration of the radiation-proof concrete slurry by using the mixer of the existing concrete slurry configuration, and it is impossible to ensure that each particle is evenly distributed in the configured concrete slurry, and then It will cause radiation holes in some parts of the concrete blocks formed with this concrete slurry
