Extraction chromatography separation device applicable to manipulator operation in hot chamber

Abstract

The invention belongs to the technical field of extraction chromatography separation devices, and discloses an extraction chromatography separation device applicable to manipulator operation in a hot chamber. The device comprises a bottom plate, a top plate, a rotary cover plate, a limiting device, an eccentric wheel compression device, a liquid storage tube, a separation column, a column tube collimating device and an inserted separation device, wherein the top plate is positioned above the bottom plate, and a supporting upright post is arranged between the top plate and the bottom plate; and the rotary cover plate is positioned above the top plate, and two upright posts are arranged between the rotary cover plate and the top plate. The device has the beneficial effects of being convenient in manipulator operation in the hot chamber, tolerable to high-intensity radiation and capable of effectively preventing repairing.

Description

technical field [0001] The invention belongs to the technical field of extraction chromatographic separation devices, and in particular relates to an extraction chromatographic separation device suitable for manipulator operation in a hot chamber. Background technique [0002] In my country's spent fuel reprocessing process, process control analysis is an important means to ensure the effectiveness of process operation. Due to the deep burn-up of spent fuel in the power reactor spent fuel reprocessing process, the radioactivity of the reprocessing liquid is higher. As a result, a large number of radioactive sample analyzes that could have been done in an analytical laboratory glove box had to be done in a hot room. The complex environment in the hot cell limits the application of many analytical methods and equipment. Therefore, the analysis of many samples needs to be pretreated by extraction chromatography in the hot chamber to separate the components to be tested from m...

Problems solved by technology

First of all, it is very difficult to complete some fine operations with manipulators in the hot chamber. The buttons, switches and other components of commercial devices are designed for manual operation, and the manipulators are completely unusable; most commercial devices are operated automatically, and there are many electrical components, which cannot withstand the heat chamber. Medium and high-intensity radiation is prone to failure and cannot be repaired; even manual devices cannot be used because most of the materials are not resistant to radiation and are easy to age and decompose; at the same time, the connection between the gas circuit and the device in the hot chamber The connection and disconnection of the separation column requires a specially designed device to be operated by the manipulator; after the commercial device fails, it cannot be repaired in the hot chamber
