Pressing machine used in sealed shielding glove box

Abstract

The invention relates to a pressing machine used in a sealed shielding glove box, and belongs to the technical field of nuclear fuel compression molding. The pressing machine comprises a pressing machine base, a hydraulic oil cylinder, a hydraulic rod, a pressing machine electrical system and a hydraulic pump, wherein the hydraulic oil cylinder is fixed on the upper end face of the pressing machine base, the pressing machine electrical system and the hydraulic pump are located below the pressing machine base, and a hydraulic oil pipe penetrates through the pressing machine base to connect the hydraulic oil cylinder with the pressing machine electrical system and the hydraulic pump; and a pressing machine mounting opening is prefabricated in a glove box bottom plate of the sealed shielding glove box, and the pressing machine base penetrates through the pressing machine mounting opening to be fixed to the lower portion of the glove box bottom plate, so that the hydraulic oil cylinder and the hydraulic rod are located in the sealed shielding glove box, and the pressing machine electrical system and the hydraulic pump are located outside the sealed shielding glove box. The problem that the pressing machine in the glove box is inconvenient to maintain can be solved, radioactive waste can be reduced, and the space in the glove box can be saved.

Description

technical field [0001] The invention belongs to the technical field of nuclear fuel compression molding, in particular to a press for sealing and shielding a glove box. Background technique [0002] In the manufacturing process of nuclear fuel or radioactive isotopes, it is often necessary to press the corresponding powder raw materials into solid pellets. The equipment required for this step is a press. Put the raw material powder into the designed mold, and use the hydraulic cylinder of the press to exert a certain pressure on the powder in the mold to make it into a pellet with a certain strength. This process is called compression molding. [0003] Nuclear fuel or radioactive isotopes are radioactive. In order to protect the health of operators and the environment from radioactive pollution, the manufacturing process is carried out in a sealed and shielded glove box. To complete the compression molding process, the traditional method is to put a whole press in a glove b...
