Problems solved by technology

[0002] At present, in the field of nuclear fuel reprocessing technology, the bench test sampling of the hot chamber is carried out due to the use of a mixing and settling tank to build a bench test device for experiments, and the distribution of the sample outlets is relatively scattered (upper, lower, left and right positions have Sampling outlet), it is necessary to use a manipulator to clamp the sampling test tube, place it at the outlet of different liquid in the mixing and settling tank to sample, and keep it until the sampling is completed, and the same tank can not be sampled at the same time
This sampling operation is difficult to sample and labor-intensive. At the same time, the probability of the test tube falling off is high, which may easily cause radioactive contamination of the experimental site.
[0003] The existing sampling device has a complex structure and takes up a lot of space, and due to the narrow space of the hot chamber, if the sampling device is large in size, it is difficult for the operator to operate in the hot chamber, so the existing sampling device cannot be used normally in the hot chamber

Abstract

The invention discloses a hot chamber sampling device, which comprises a three-way magnetic valve (2), a magnetic valve controller (1), a sample tube (9), a bench (6) and a sampling tube (8). The three-way magnetic valve (2) is connected on an experimental liquid flow pipeline (7) which needs to carry out sampling and is controlled by the magnetic valve controller (1). The sampling tube (8) between the three-way magnetic valve (2) and the sample tube (9) is provided with an empty. The bench (6) is provided with a sample tube clamping groove. The device has simple structure, smaller volume andsafe operation, reduces the residual in the sampling pipeline and can realize remote semi-automatization sampling operation in the hot chamber.

Description

technical field [0001] The invention relates to the technical field of nuclear fuel reprocessing, in particular to a nuclear fuel reprocessing heat chamber sampling device. Background technique [0002] At present, in the field of nuclear fuel reprocessing technology, the bench test sampling of the hot chamber is carried out due to the use of a mixing and settling tank to build a bench test device for experiments, and the distribution of the sample outlets is relatively scattered (upper, lower, left and right positions have Sampling outlet), it is necessary to use a manipulator to clamp the sampling test tube, place it at the different feed liquid outlets of the mixing and settling tank to sample, and keep it until the sampling is completed, and the same tank can not be sampled at the same time. This sampling operation is difficult to sample, and the labor intensity is high. At the same time, the probability of the test tube falling off is high, which may easily cause radioa...
