Fully automatic shielding transfer door

Abstract

The invention provides a fully automatic shielding transfer door. The fully automatic shielding transfer door is used for transferring materials from the exterior of a hot room to the interior of thehot room, wherein a first through hole communicating with the exterior of the hot room is formed in the horizontal direction of a shielding block, cavities which are matched with the shape of a rotarydoor are formed inside a front seat and a rear seat, and inlets which communicate with the cavities and the first through hole separately are formed in the side, near the exterior of the hot room, ofthe front seat; outlets which communicate with the cavities and the interior of the hot room separately are formed in the side, near the interior of the hot room, of the rear seat, the rotary door isarranged in the cavities, and a second through hole is formed in the horizontal direction of the rotary door; the first through hole, inlets, second through hole and outlets communicate sequentiallyso as to form a passage, and a driving mechanism is used for driving the rotary door to rotate freely in the cavities around a vertical shaft of the rotary door, so that the second through hole in therotary door communicates with or is staggered with the inlets and outlets in the front and rear of the rotary door so as to open or close the transfer door. The transfer door can not only ensure radiation safety of personnel, but also realize automatic operation of the whole process.

Description

technical field [0001] The invention relates to the technical field of nuclear fuel reprocessing, in particular to a fully automatic shielding transfer door for transporting materials from outside the heating chamber to inside the heating chamber. Background technique [0002] In the nuclear fuel reprocessing process, radioactive materials need to be processed and treated in the corresponding hot chamber according to the specific process flow. Radioactive materials are first placed in special shielded transfer containers and then transported into the thermal chamber through the thermal chamber transfer door. [0003] The hot chamber is a shielded space for high-radioactive experiments and operations, and a large amount of radioactive substances need to be transferred into it, which has strong radiation. In order to realize the safe transfer of radioactive materials, the design of the hot cell transfer door is particularly important. However, the existing hot cell transfer ...
