Abstract

The invention belongs to the technical field of liquid-phase sampling in a hot cell extraction process in the field of nuclear fuel after-treatment and discloses an instantaneous sampling apparatus for a radioactive bench test. The apparatus is arranged on the bottom of a radioactive bench and includes a sampling pipeline, a first three-way valve, a second three-way valve, an exhaust pipe, a sampling bottle bracket, a fixing sleeve tube, a fixing sleeve tube supporter and a sampling bottle bracket handle. The sampling bottle bracket has a drawable structure and is provided with a sampling bottle trough and the sampling bottle bracket handle. The fixing sleeve tube supporter is arranged above the sampling bottle bracket. The fixing sleeve tube is welded to the fixing sleeve tube supporter. The fixing sleeve tube is arranged on a corresponding position above the sampling bottle trough and can be matched with and connected to the sampling pipeline. The sampling pipeline includes an organic phase sampling tube and a water phase sampling tube. The sampling apparatus has simple structure and is easy to operate, saves space on the bench, enables the bench to be hoisted conveniently, and can effectively avoids retention and overflow of a sample liquid.

Description

technical field [0001] The invention belongs to the technical field of liquid sample sampling in a hot chamber extraction process in the field of post-treatment of nuclear fuel, and in particular relates to an instantaneous sample sampling device for radioactivity bench experiments. Background technique [0002] Commonly used equipment for the hot chamber extraction process in the field of nuclear fuel reprocessing is mixing and settling tanks, extraction columns, etc. Taking the mixing-settling tank experiment as an example, when carrying out experiments in a hot chamber, a combination of multiple mixing-settling tanks is generally used, installed on a platform of a certain size, and hoisted as a whole into the hot chamber. In the experiment, samples need to be collected from the outlet flow at both ends of each mixing and settling tank, and the equipment in the heat chamber is operated by manipulators. In addition to the mixing and settling tank, a typical hot chamber ext...
