Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in figures 1-4, this Continuous Flow Analysis instrument reagent feedway disclosed by the invention includes pallet 5, and pallet 5 is provided with the multiple draw-in groove of string, one reagent bottle 1 of each placement in each draw-in groove；The opposite sides of each reagent bottle 1 is respectively equipped with infrared transmitting tube 3 and infrared receiving tube 4, and the rational height of infrared transmitting tube 3 and infrared receiving tube 4 is all consistent with the minimum liquid level of reagent bottle 1；Reagent feedway also includes signal conditioning circuit, controller, buzzer 2 and multiple light emitting diode 9 equal numbers of with reagent bottle 1；Infrared receiving tube 4 is connected with signal conditioning circuit, and signal conditioning circuit is connected with controller, and controller is connected with buzzer 2 and multiple light emitting diode 9.Infrared transmitting tube 3, infrared receiving tube 4 and light emitting diode 9 are each provided on pallet 5, and light emitting diode 9 is located at the side of corresponding reagent bottle 1.Reagent bottle 1 is square, is longitudinally provided with one dividing plate in reagent bottle 1, and reagent bottle 1 lumen segmentation is become main bottle chamber 7 and secondary bottle chamber 8 by this dividing plate, and the top in main bottle chamber 7 and secondary bottle chamber 8 is respectively provided with a bottleneck；The bottom of dividing plate offers the inlet opening 6 in a main bottle chamber 7 of connection and secondary bottle chamber 8.The bottleneck in the main bottle chamber 7 of each drug bottle 1 is designed with a reagent inlet pipe 12 for providing reagent to Flow Analyzer, and reagent inlet pipe 12 is provided with charging electromagnetic valve 11；It is in charge of 13 on reagent inlet pipe 12 and in the flushing that has been further connected below of charging electromagnetic valve 11, and rinses and be in charge of 13 and be provided with scouring electromagnetic valve 14.Flushing is in charge of 13 and is all aggregated into equipped with in the reagent bottle of pure water.Charging electromagnetic valve 11 and scouring electromagnetic valve 14 are all carried out on-off control by controller, it is achieved enter medicine and flushing.
The signal conditioning circuit of the present invention includes signal and amplifies and correcting circuit and analog to digital conversion circuit, and controller is single-chip microcomputer.By infrared transmitting tube 4 and infrared receiving tube 4, the fluid level data in reagent bottle 1 is acquired, the collection signal of reflection reagent bottle 1 level information amplifies and correcting circuit through signal, and be converted into after digital signal be sent to single-chip microcomputer process through analog to digital conversion circuit, compared with preset value, and then judge the liquid level position in reagent bottle 1, finally judge whether to start warning circuit.
The infrared transmitting tube 3 of reagent feedway of the present invention launches infrared ray all the time, and after attenuating liquid in reagent bottle 1, the light intensity that the infrared receiving tube 4 of opposite side is experienced is less, it is impossible to produce electric current, thus light emitting diode 9 and buzzer 2 are reactionless；Only when the reagent liquid level in certain reagent bottle 1 is lower than the setting height of the infrared transmitting tube 3 of the present invention and infrared receiving tube 4, the light intensity that infrared receiving tube 4 is experienced increases, photoelectric current becomes big, touch alarm indicator circuit, the light emitting diode 9 of buzzer 2 and this reagent bottle 1 correspondence starts sound and light alarm, reminds and supplements reagent in time.
When supplementing reagent solution in the reagent bottle 1 producing to report to the police, first liquid is injected from the bottleneck in secondary bottle chamber 8, then liquid can be flowed into main bottle chamber 7 from bottom liquid inlet hole 6 by under atmospheric pressure effect, finally makes main bottle chamber 7 keep consistent with the liquid level in secondary bottle chamber 8 or be more or less the same.After reagent has supplemented, the light that infrared transmitting tube 3 sends is blocked by reagent medicinal liquid again, and the light intensity that infrared receiving tube 4 is experienced reduces, and alarm indicator circuit disconnects, and stops sound and light alarm.Therefore, there is no need to from analyser, take off reagent bottle 1 and just can carry out fluid infusion online, save instrumentation step, decrease operating error.
Inlet opening 6 is positioned at the side in main bottle chamber 7 and is provided with cover plate 10, and cover plate 10 is hinged on above inlet opening 6.When the liquid phase in main bottle chamber 7 and secondary bottle chamber 8 is similar, cover plate 10 covers inlet opening 6, it does not have liquid flows；Only when the liquid in main bottle chamber 7 fewer than the liquid in secondary bottle chamber 8 a lot of time, cover plate 10, by the pressure differential jack-up at inlet opening 6 two ends, has liquid to flow into main bottle chamber 7 from secondary bottle chamber 8.
The inwall of inlet opening 6 is provided with the helicla flute being led to main bottle chamber 7 by secondary bottle chamber 8, and spiral fluted top opening upwards extends expansion, spiral fluted end extends to the bottom in main bottle chamber 7, helicla flute makes liquid pass through inlet opening 6 when flowing into main bottle chamber 7 from secondary bottle chamber 8, forming spiral helicine liquid stream, flow rate of liquid is very fast on the one hand, on the other hand, deposit bottom main bottle chamber 7 can be rushed by spiral helicine liquid stream, and minimizing deposition also can be uniform by liquid agitation.
When experiment starts and end needs detergent line, the charging electromagnetic valve 11 on reagent inlet pipe 12 cuts out, open rinsing the scouring electromagnetic valve 14 being in charge of on 13, it may be achieved detergent line；When needs are tested, then by rinsing scouring electromagnetic valve 14 Close All being in charge of on 13, open the charging electromagnetic valve 11 on reagent inlet pipe 12, it is achieved normally enter reagent process.Feed system and detergent line interconnection are got up by the present invention, improve work efficiency, can simplify repeatedly tube drawing catheterization procedure, raising efficiency, reduction human error in experimentation simultaneously, reduce the subjective reagent caused of slipping up and access wrong probability.
