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
What the present invention relates to a kind of irradiation sample varies device, particularly a kind of multi-channel sample changer.
Background technology
Neutron activation analysis is a kind of very high trace element analysis method of sensitivity, and the method utilizes pile neutron and sample generation nuclear reaction that sample is activated, and the radioactivity measuring sample after activation is to realize the quantitative test to element contained by sample.In neutron activation analysis process, first sample is admitted to reactor irradiation, cools after irradiation, delivers to detector and measures, and sends in radioactivity hold-up vessel and store after measuring.
In neutron activation analysis system, the irradiation of sample, cooling and measurement be realized, meet the requirement of the aspects such as radiation protection, all need just can be completed by automatic sample-changing device.At present, the automatic sample-changing device for neutron activation mainly adopts mechanical arm, puts into different positions by gripper of manipulator sample thief.But because mechanical arm exists complex structure, equipment cost is high, control method is difficult to the series of problems such as grasp, therefore needs a kind of new automatic sample-changing device of design to solve mechanical arm the problems referred to above for existing during automatic sample-changing.
Summary of the invention
For solving the complex structure that existing neutron activation analysis automatic sample-changing device exists, equipment cost is high, and control method is difficult to the problems such as grasp, the invention provides a kind of multi-channel sample changer, specific as follows:
This multi-channel sample changer comprises support, sample-transporting tube, 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, and support is provided with through hole with race rabbit mouth piece corresponding position; Sample-transporting tube be positioned at the opposite side of support and openend towards support, sample-transporting tube bottom is provided with air hole, and bottom and cylinders connect, and is vertically moved by the control realization of cylinder; Sample-transporting tube is also connected with drive unit, by the control realization transverse shifting of drive unit; Under the Collaborative Control of cylinder and drive unit, sample-transporting tube can move to each through hole of support with the UNICOM realized with run rabbit mouth piece; The part that sample-transporting tube openend contacts with support takes seal approach.
It is preferred for described support being also provided with hand sampling mouth; Described drive unit is preferably motor; The location of sample-transporting tube shift position is preferably and adopts photoelectric sensor location.
The course of work of multi-channel sample changer of the present invention is as follows:
First, make sample-transporting tube aim at sample introduction by the control of drive unit and run rabbit mouth piece or hand sampling mouth, sample-transporting tube realizes running with sample introduction being communicated with of rabbit mouth piece or hand sampling mouth under the control of cylinder; By compressed gas-driven or manually sample is sent into sample-transporting tube.
Then, make sample-transporting tube aim at sample presentation by the control of drive unit and run rabbit mouth piece, sample-transporting tube realizes running being communicated with of rabbit mouth piece with sample presentation under the control of cylinder; By the compressed gas-driven entered by sample-transporting tube air hole, sample is sent into desired location, realize automatic sample-changing.
Multi-channel sample 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 safeguard, sample between the diverse locations such as irradiation terminal, gamma survey terminal, radioactive waste tank, delayed neutron measurement terminal can be realized transmit automatically, and then more achieve the robotization of sample irradiation, cooling, measurement in neutron activation analysis process convenient and efficient.
