Abstract
The invention relates to a sample changer for irradiated samples. Aiming at solving the problems of complex structure, high equipment cost and difficulty in mastering a control method of an existing automatic sample changer for neutron activation analysis, the invention provides a multi-channel sample changer. The multi-channel sample changer comprises a bracket, a sample transfer tube, an air cylinder, a driving device and two or more rabbit interface tubes fixed on the same side of the bracket, wherein the sample transfer tube is positioned on the other side of the bracket and realizes the longitudinal movement through the control of the air cylinder and the horizontal movement through the control of the driving device, and under the collaborative control of the air cylinder and the driving device, the sample transfer tube can move to all through holes of the bracket to be communicated with the rabbit interface tubes. The multi-channel sample changer provided by the invention is small in size, simple and compact in structure, low in cost, and easy to maintain, the control method is easy to master, and the automation of sample irradiation, cooling and measurement in a neutron activation analysis process can be realized.
Description
Technical field
The present invention relates to a kind of device that varies of irradiation sample, particularly a kind of hyperchannel changer.
Background technology
Neutron activation analysis is the very high trace element analysis method of a kind of sensitivity, and this method utilizes pile neutron and sample generation nuclear reaction to make the sample activation, measures the radioactivity of activation back sample to realize the quantitative test to the contained element of sample.In the neutron activation analysis process, sample at first is admitted to reactor irradiation, cools off behind the irradiation, delivers to detector and measures, and sends into after the measurement in the radioactivity hold-up vessel to store.
In the neutron activation analysis system, realize irradiation, cooling and the measurement of sample, satisfy the requirement of aspects such as radiation protection, all need just can finish by varying device automatically.At present, the device that varies automatically that is used for neutron activation mainly adopts mechanical arm, grasps sample by mechanical arm and puts into different positions.But because there is complex structure in mechanical arm, equipment cost is high, and control method is difficult to a series of problems such as grasps, therefore needs a kind of new device that varies automatically of design to solve the problems referred to above that mechanical arm exists when varying automatically.
Summary of the invention
Automatically vary the complex structure that device exists for solving existing neutron activation analysis, equipment cost is high, and control method is difficult to problems such as grasp, the invention provides a kind of hyperchannel changer, and is specific as follows:
This hyperchannel changer comprises support, sample transfer pipeline, cylinder, drive unit, race rabbit mouth piece, and described race rabbit mouth piece is two or more, is fixed on the same side of support, is provided with through hole with race rabbit mouth piece corresponding position on the support; The sample transfer pipeline is positioned at the opposite side of support and openend towards support, and sample transfer pipeline bottom is provided with air hole, and the bottom is connected with cylinder, and the control by cylinder realizes vertically moving; The sample transfer pipeline also is connected with drive unit, and is laterally mobile by the control realization of drive unit; Under the Collaborative Control of cylinder and drive unit, the sample transfer pipeline can move to each through hole of support to realize and the UNICOM of running the rabbit mouth piece; The part that sample transfer pipeline openend contacts with support is taked seal approach.
Also be provided with the hand sampling mouth on the described support for preferred; Described drive unit is preferably motor; The location of sample transfer pipeline shift position is preferably adopts the photoelectric sensor location.
The course of work of hyperchannel changer of the present invention is as follows:
At first, the control by drive unit makes the sample transfer pipeline aim at sample introduction and runs rabbit mouth piece or hand sampling mouth, and the sample transfer pipeline is realized under the control of cylinder and being communicated with of sample introduction race rabbit mouth piece or hand sampling mouth; By compressed gas-driven or manually sample is sent into the sample transfer pipeline.
Then, the control by drive unit makes the sample transfer pipeline aim at sample presentation and runs the rabbit mouth piece, and the sample transfer pipeline is realized under the control of cylinder and being communicated with of sample presentation race rabbit mouth piece; By the compressed gas-driven that is entered by sample transfer pipeline air hole sample is sent into desired location, realize varying automatically.
Hyperchannel changer volume of the present invention is little, simple and compact for structure, cost is low, control method is easy to grasp, be easy to maintenance, can realize that sample transmits automatically between the diverse locations such as irradiation terminal, gamma survey terminal, radioactive waste jar, delayed neutron measurement terminal, and then realize the robotization of sample irradiation, cooling, measurement in the neutron activation analysis process more convenient and efficient.
