Device for taking samples of radioactive and/or toxic suspensions containing solids |
摘要 |
A device for taking samples of radioactive and/or toxic suspensions containing solids includes a single needle head for taking samples from a liquid circulating in a pipe loop. The liquid is drawn off into a sample vessel with the liquid being pumped by a vacuum-assisted air lift. In order to minimize the risk of clogging in such a sampling device and to be able to obtain reliably representative samples, the one-needle head has a mixing chamber which widens conically toward the interior of the housing of the sampling device. The feed line extends into this conical mixing chamber to a location just ahead of the needle opening in the base. The opening at the end of the feed line has a larger diameter than the inside diameter of the sampling needle disposed in the needle head. With this configuration, a higher flow velocity is achieved together with a high degree of turbulence of the liquid in the sampling device.
