Automatic sampling and weighing device for liquid samples

Abstract

The invention provides an automatic sampling and weighing device for liquid samples. The sampling and weighing device is provided with a rotating table I, a rotating table II, a rotating table III, a transferring table I, a transferring table II, a transferring table III, a clamping holder I, a clamping holder II, an electrical liquid transferring device and a sensor on the upper part of the working platform of the sampling and weighing device, wherein the rotating table I is used for placing a bottle rack I of a bottle A; the rotating table II is used for placing a bottle rack II of a bottle B; the rotating table III is used for placing a bottle rack III of a sampling head; the transferring table I is used for transferring the bottle A; the transferring table II is used for transferring the bottle B; the transferring table III is used for transferring the sample in the electrical liquid transferring device; the clamping holder I is used for clamping the bottle A; and the clamping holder II is used for clamping the bottle B. The sampling and weighing device is provided with an electronic balance and a automatic control system in a shielding box below the working platform, wherein the electronic balance is used for weighing the sample, and the automatic control system is connected to the components respectively. The automatic sampling and weighing device in the invention can automatically sample and weigh the liquid in a sealed container in an intensive ionizing radiation environment; the device can continuously sample and weigh the sample for multiple times, and can continuously sample and weigh different samples; and each component in the sampling and weighing device can also be independently operated.

Description

technical field [0001] The invention belongs to the technical field of liquid sample packaging devices, in particular to an automatic sampling and weighing device for liquid samples, especially an automatic device capable of accurately sampling and weighing well-sealed bottled radioactive liquids in a strong ionizing radiation environment . Background technique [0002] At present, the sampling method of bottled radioactive liquids in the environment of strong ionizing radiation (such as in the thermal chamber of nuclear waste liquid treatment) is generally to use manipulators and other tools to hold the pipette remotely, and draw a certain amount from the liquid storage bottle. Put the sample into the receiving bottle as a small sample, then transfer it out by other tools and put it in a protective box or a fume hood, then use a hand-operated pipette or pipette to quantitatively sample, and calculate the sample by measuring the density of the sample or transfer the radioac...
