Example Embodiment

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0030] like figure 1 As shown, a device for sampling radioactive liquid samples at different depths in a container includes a sampling depth control system, a liquid flow direction control system and a sampling volume control system, and the liquid flow direction control system is between the depth control system and the sampling volume control system. For connecting depth control system and sampling volume control system.

[0031] The sampling depth control system is mainly used to draw samples of different depths in the container, including the sampling tube and the bracket that moves r...

Abstract

The invention provides an apparatus for sampling a radioactive liquid sample having different depths in a container. The problem of inconvenience in sampling of the radioactive liquid having different depths in the container is solved. The apparatus includes a sampling tube, a suction device and a sampling bottle, the sampling end of the sampling tube is provided and connected with a support, a connecting piece for mutually communicating the sampling tube, the suction device and the sampling bottle is arranged and connected among the sampling tube, the suction device and the sampling bottle, and stop valves are arranged between the sampling tube and the connecting piece and between the sampling bottle and the connecting piece. The suction device is drawn and pushed to discharge a gas in the device and pump the liquid sample into the sampling bottle, and the connecting piece cooperates with the stop valves to make the liquid flow unidirectionally, so the integral apparatus guarantees the quality of the sampled sample, and also has the advantages of simple structure, convenience in operation, and high applicability.

Description

technical field [0001] The invention belongs to a liquid sample sampling device, in particular to a sampling device for radioactive liquid samples at different depths in a container. Background technique [0002] In scientific research and production experiments, the study of liquid samples in heterogeneous media often requires accurate sampling and analysis of samples at different depths in the container. In order to ensure the quality of sampling, part of the sample at the front end of the sample sampling tube needs to be discarded during sampling. For the sampling of radioactive liquid samples, issues such as radioactive pollution and secondary waste generation need to be considered. [0003] Due to the limitations of the device itself, the existing sampling device can only sample samples at the same depth, and during the sampling process, most of the samples are extracted in large quantities, and the samples at the front end and the samples required at the back If they ...
