Squint window structure for hot cell

Abstract

The invention relates to the technical field of hot cell structures, and further relates to a squint window structure for a hot cell. The squint window structure is characterized by comprising a squint window pressing plate (1), an inner glass pressing frame (2), a squint window reinforcing frame (3), first squint window glass (41), second squint window glass (42) and a squint window outer frame (5); the first squint window glass (41) is positioned between the inner glass pressing frame (2) and the squint window reinforcing frame (3), and the inner glass pressing frame (2) is used for fixedlypressing the first squint window glass (41) into the squint window reinforcing frame (3); the squint g window frame (5) is fixed on the side, opposite to the inner glass pressing frame (2), of the squint window reinforcing frame (3); and the second squint window glass (42) is fixed in the squint window frame (5). The squint window structure for the hot cell is convenient for an operator to observeand operate, and the accuracy and convenience of the operation are improved; radioactive rays in the hot cell can be prevented from leaking out, radiation pollution is avoided, and the environment and the personal safety of workers are effectively protected; and enlarging of visual angle of the operator is facilitated.

Description

technical field [0001] The invention relates to the technical field of thermal chamber structures, and further relates to a thermal chamber viewing window structure. Background technique [0002] A hot cell is a shielded chamber for highly radioactive experiments and operations. It is isolated from its surroundings. The inner wall is often covered with stainless steel, which is convenient for washing and decontamination. The exterior walls are heavy concrete structures to protect against gamma radiation. The front wall of the hot cell is equipped with a viewing window of lead glass or high-density liquid, and is equipped with a robot for remote operation. The back wall is equipped with an iron door, which can be accessed, cleaned, installed and dismantled if necessary. A light box is installed on the top for lighting, and a transport trolley is installed to transport items in and out of the hot chamber. It is ventilated by the exhaust system to keep the heat chamber wor...

AI Technical Summary

Problems solved by technology

[0003] As the main part of the hot cell, the structural design of the viewing window should not only facilitate the observation of the scene inside the thermal chamber, but also provide a high degree of sealing. The existing viewing window cannot meet the above requirements. Therefore, the industry urgently needs a A Peeping Window for Observing the Interior of a Thermal Type
