Description

Automatic sample receiving and sending device of pneumatic sample feeding system Technical Field The invention relates to the technical field of nuclear sample conveying, in particular to an automatic sample receiving and transmitting device of a pneumatic sample conveying system. Background Samples produced in the nuclear related process system are transported to an analysis center for analysis and processing, and the samples are typically contained in sample vials and then transported through sample vial protectors. The initial nuclear related process sample transportation is generally completed manually, so that the efficiency is low and the potential safety hazard exists. At present, due to the improvement of the degree of automation, radioactive nuclear process samples are generally arranged in a sample protection device and are conveyed through an automatic conveying system, and the sample conveying of a pneumatic sample conveying system becomes an important conveying mode. Because the samples generated by the process stations of different process lines are different, and because the analysis center needs to receive different samples at different stations, the samples are conveyed from the process stations to the analysis center and are generally transferred and orderly sent to the analysis center for analysis stations through the sub-item sets. The sample conveying transfer of the pneumatic sample conveying system generally adopts an automatic receiving and transmitting device to clamp and transmit samples from a sample receiving end to a sample transmitting end or complete the opposite action process by adopting an automatic mechanical clamping jaw. In order to ensure safe, orderly, accurate and efficient sample transportation, a sample sending end needs to automatically send samples into a conveying pipeline and send the samples through certain air pressure. The problems that samples are large in variety, large in quantity and radioactive in process, the samples are not timely transported in manual transmission, radioactive samples are easy to leak and the like exist, potential safety hazards exist, and meanwhile the whole process production is influenced. Therefore, it is necessary to provide an automatic sample receiving and sending device of a pneumatic sample feeding system to solve the above-mentioned problems.
