Problems solved by technology

[0002] The loop coolant of nuclear power plant reactors and the purification treatment of spent fuel pool water are mostly purified by ion exchange resin, but the waste resin after failure is organic waste, which is easy to produce combustible gas during irradiation, pyrolysis or biodegradation, and contains relatively high Sulfur, nitrogen, and the degraded products are highly corrosive to equipment and storage containers. Therefore, samples of the waste resin after preliminary treatment will be collected and sent to the laboratory for testing. Because the waste resin is radioactive and radionuclides, The sampling process should meet the requirements of automatic sampling. At present, domestic equipment with similar functions can take samples from the pipeline, but the degree of automation is not high, and there are limitations in use. After sampling, there will be waste liquid media remaining in the sample collection pipeline. Among them, the potential safety hazard is relatively large. To solve the above problems, this application proposes an automatic waste resin sampler

Abstract

The invention relates to the technical field of waste resin samplers, and discloses an automatic waste resin sampler which comprises a protective shell, a controller is fixedly sleeved with one side of the bottom of the protective shell, and a partition plate is arranged on the outer side of the controller. Two small servo motors in the transmission mechanism respectively drive a lead screw to rotate, so that a transmission plate and a transition shaft in the sampling mechanism mounted on the side surface of the transmission plate are synchronously pushed under the action of a programmable logic controller to perform linear reciprocating motion; then, the sampling rod connected with the transition shaft enters the pipeline adapter, and the waste resin entering the pipeline adapter is sampled by utilizing a placing groove formed in the sampling rod and is synchronously reset in a reciprocating manner; and then the sample in the placing groove can be directly purged into the sample collecting mechanism to be collected by utilizing the cooperation of the purging mechanism and the gas guide pipe, and finally, the whole sampling operation is automatically completed.
