Radioactive source pneumatic conveying control detection device

Abstract

The invention belongs to the field of radioactive source application and particularly relates to a radioactive source pneumatic conveying control detection device. An existing radioactive source pneumatic conveying system cannot accurately control and determine the position of a radioactive source in the using process, and workers are subject to the risk of accidental exposure. The radioactive source pneumatic conveying control detection device comprises an air compressor connected with a radioactive source storage tank through an air flow conveying pipeline. A first air flow channel and a radioactive source channel which are communicated with each other are positioned in the radioactive source storage tank, the air flow conveying pipeline is connected with the first air flow channel of the radioactive source storage tank, the radioactive source channel of the radioactive source storage tank is connected with a radioactive source conveying pipe, a plurality of proximity switches for sensing the passage of a radioactive source are positioned outside the radioactive source conveying pipe; and the proximity switches are connected with a control system. The device can control conveying operation of the radioactive source, the position of the radioactive source in the operation process is accurately mastered, and the accidental exposure to the workers caused by unclearness of the position of the radioactive source is avoided.

Description

technical field [0001] The invention belongs to the application field of radioactive sources, and in particular relates to a radioactive source pneumatic transmission control and detection device. Background technique [0002] Radioisotope neutron sources have the advantages of small size, simple structure, and portability. and scientific research fields have been widely used. [0003] In practical applications, the isotopic neutron source can be delivered pneumatically. Under the action of compressed air, the neutron source moves rapidly along the transfer pipeline between the storage tank and the irradiation target location. The pneumatic transmission method has the advantages of fast transmission speed and short time. However, although the neutron source is restricted to move in the transmission pipeline, since the neutron source is not attached to any rigid or flexible fixed connection constraints in the direction of motion, when the neutron source reciprocates in the...

AI Technical Summary

Problems solved by technology

However, although the neutron source is restricted to move in the transmission pipeline, since the neutron source is not attached to any rigid or flexible fixed connection constraints in the direction of motion, when the neutron source reciprocates in the transmission pipeline under the action of compressed air , there are certain uncertainties in its movement process and stop position, that is, after the compressed air pushes the neutron source to move in the transmission pipeline, it is unknown when and where it will arrive, and where it will eventually stop

The neutron source is a source of ionizing radiation, and failure to accurately track the neutron source's motion and determine where it stays poses a risk of accidental exposure to workers
