Abstract

The invention discloses an extruder for manufacturing composite particles capable of efficiently shielding neutron gamma radiation, which comprises a rack, a first motor is mounted at one end of the rack in an embedded manner, and a first feed hopper and a second feed hopper are fixed at the top of the rack in a penetrating manner; the fixed material guide disc is fixed on the inner wall of the rack, uniform mixing holes are correspondingly formed in the fixed material guide disc and the movable material guide disc at equal angles, and a positioning rod is fixed on the inner wall of the rack; the extrusion disc is installed at the other end of the rack, a movable shaft is installed on a bearing on the outer side of the extrusion disc, a material cutting cover is fixed to the movable shaft, an inlet groove is formed in the side of the material cutting cover, and an airflow conveying pipe is installed at the side end of the movable shaft in a penetrating mode. According to the extruder for manufacturing the composite particles for efficiently shielding neutron gamma radiation, uniform mixing of materials is achieved, the forming effect is improved, meanwhile, single formed particles are rapidly cooled, and adhesion is avoided.

Description

technical field [0001] The invention relates to the technical field of extruders, in particular to an extruder used for producing composite particles with high efficiency shielding neutron gamma radiation. Background technique [0002] The increasing development of the atomic energy industry has brought many hidden dangers to radiation safety. Among many radiations, neutron gamma rays have stronger penetrating power and are difficult to shield. In the existing technology, composite materials are usually used to achieve efficient shielding. Traditional composite materials The shielding materials include polymer-based composite shielding materials, metal-based composite shielding materials, and glass-based composite shielding materials. Among them, polymer-based composite shielding materials mostly use organic polymer materials as the matrix, and powders with anti-radiation functions are added as reinforcing fillers. Extrusion, molding and other processes are processed, but th...
