Description
Technical field
The invention belongs to fluid sample packaging device technical field, be specifically related to a kind of fluid sample automatic sampling device, the aut.eq. that especially can under the dense ionization radiation environment, accurately take a sample the bottled preferably radioactive liquid of sealing.
Background technology
At present; The sampling mode of the bottled radioactive liquid of (in the nuclear waste processing cell) under the dense ionization radiation environment; Generally be to wait the remote clamping pipette of instrument through the manipulator, from liquid storage bottle, draw a certain amount of sample, put into receiving bottle as sample by the people; Through other instrument it is shifted out being placed in protective housing or the fuming cupboard again, use manual manipulation pipettor or transfer pipet quantitative sampling again.But this method can only be useful in the non-direct quantitative sampling of the liquid in container such as ground glass stoppered bottle of uncovered bottle or poor sealing in the dense ionization radiation environment, is not suitable for the direct quantitative sampling of the bottling liquid of good sealing performance piston type bottle cap sealing; In such sampling process, sample very easily drips and causes radioactive contamination, and the radioactive sample of too many levels shifts and by the mode of the manual quantitative sampling of people, increased the risk of operating personnel's irradiation dose and radioactive contamination environment.The Chinese patent bibliographic data base discloses a kind of utility model name and has been called " radioactive source packaging device " (patent No.: ZL 99202096.4); This utility model adopts the hand operating mechanism instrument under motor-driven rotating mechanism cooperates, to open bottle cap; Manually carry out the transfer and the packing of sample, go control branch loading amount through observing the manual controlled valve of liquid level scale.The disclosed another kind of utility model name of Chinese patent bibliographic data base is called " the remote radioactive liquid of protected type is inhaled moving device " (patent No.: ZL 92231059.9); This utility model adopts the manually-operated injection needle tube to take out negative pressure, makes the transfer pipet (placing in the screened room) that connects through flexible pipe draw sample from uncovered sample bottle.The Chinese patent bibliographic data base also discloses other similar devices; Utility model patent technology like " isotope automatic packer " (patent No.: ZL 02244994.9); Automatically divide appearance through computer control; Do not uncap, function such as lid, and can not uninterruptedly divide appearance to a plurality of samples automatically and continuously." automatic subpackaging device " for another example (patent No.: ZL 2,005 2 0032960.2) utility model patent technology; Be the patent that patented claim unit of the present invention several years ago applies for, be a kind of utility model device that is exclusively used in the radioactive drugs packing, the most approaching with functions of use of the present invention; But the mode of its automatic subpackaging is to adopt peristaltic pump quantitative transfer liquid from unsealed liquid storage bottle; It is to adopt traditional acupuncture mode to the mode that the cillin bottle of taking out negative pressure in advance injects product equally, and just the operation of acupuncture has been replaced manually by electronic, is easy to pollute cillin bottle during the withdraw of the needle and causes bottle cap loosening; Do not possess sample bottle and uncap, cover function; And the versatility of device is poor, and promptly a packing flow process can only be carried out packing to a kind of product, when needing the packing different product; Must clean whole pipe system, with producing extra radioactive liquid waste.Also press for a kind of device that can under the dense ionization radiation environment, carry out the automatic ration sampling simultaneously in the reality to air-tight bottle dress radioactivity fluid sample.
