a press mounting port is prefabricated on a glove box bottom plate of the sealed shielding glove box, a press base penetrates through the press mounting port and is fixed below a glove box bottom plate, so that the hydraulic oil cylinder and the hydraulic rod are located inside the sealed shielding glove box, and an electric system and a hydraulic pump of the press are located outside the sealed shielding glove box.
Further, the press for sealing and shielding the inside of the glove box further comprises a press top plate located above the press base, and the press top plate is connected with the upper end face of the press base through a press top plate fixing rod.
Further, according to the press for sealing and shielding the inside of the glove box, the bottom plate of the glove box and the press base are provided with the fixing bolt holes which correspond to each other one by one, and the press base is fixed below the bottom plate of the glove box through the fixing bolts.
Further, according to the press for sealing and shielding the glove box, a rubber sealing ring is arranged between the contact surface of the bottom plate of the glove box and the base of the press, and is used for sealing and shielding the glove box.
Still further, as for the press for sealing and shielding the inside of the glove box, an annular groove is prefabricated on the contact surface of the press base and the glove box bottom plate, and the rubber sealing ring is positioned in the annular groove.
Further, as for the press machine used for sealing and shielding the inside of the glove box, the rubber sealing ring is positioned on the inner side of the fixing bolt hole.
The press for sealing and shielding the inside of the glove box has the following remarkable technical effects:
(1) compared with the scheme that the whole press is placed in a glove box, the invention obviously reduces the occupied space in the glove box, and greatly reduces the articles polluted by radioactivity.
(2) According to statistics, more than 80% of faults of the press occur in the electric system and the hydraulic pump, the electric system and the hydraulic pump are arranged outside the glove box, so that the maintenance or replacement is convenient, and replaced parts are not arranged inside the glove box and are prevented from being subjected to radioactive contamination, so that the parts can be treated as common articles instead of radioactive waste.
(3) The hydraulic oil is replaced outside the glove box without being taken into the glove box, and the hydraulic oil replaced inside the glove box can be treated as common waste because the hydraulic oil does not contact radioactive substances.
Drawings
FIG. 1 is a schematic view of a press configuration for sealing inside a shielded glove box provided in an embodiment of the present invention;
wherein, 1-the bottom plate of the glove box; 2-glove box wall; 3-a rubber sealing ring; 4-fixing the bolt; 5-a hydraulic oil cylinder; 6-press base; 7-a hydraulic rod; 8-press electrical system and hydraulic pump; 9-hydraulic oil pipe; 10-press top plate fixing rods; 11-press top plate.
Detailed Description
The invention is further described with reference to specific embodiments and drawings attached to the description.
Fig. 1 shows a schematic structural diagram of a press used in a sealed and shielded glove box provided by the invention, the press is installed in the sealed and shielded glove box and comprises a press base 6, a hydraulic oil cylinder 5, a hydraulic rod 7, a press electrical system and a hydraulic pump 8, the hydraulic rod 7 is positioned in the hydraulic oil cylinder 5 and can slide up and down along the inner wall of the hydraulic oil cylinder 5, the hydraulic oil cylinder 5 is fixed on the upper end surface of the press base 6, the press electrical system and the hydraulic pump 8 are positioned below the press base 6, the hydraulic oil cylinder 5 is connected with the press electrical system and the hydraulic pump 8 through a hydraulic oil pipe 9 penetrating through the press base 6, and the hydraulic rod 7 is pushed to move up and down through the control of the press electrical system and the hydraulic pump 8 on the hydraulic oil cylinder 5, so that the powder in a die is pressed, and the powder becomes a pellet biscuit with certain strength.
