Embodiment
Embodiment one
The mixed concentration on-line measurement device that the present invention is provided, including housing 1, screen pack 3, laser generator 4, collimation lens 5,
Concavees lens 65 and PLC control system；The PLC control system includes laser pickoff 61, processor 62, digital display screen 63；It is described
Runner 2 is provided with the middle of housing 1；The screen pack 3 is arranged on the top of the runner 2；The laser generator 4 is fixed on described
The outside of housing 1, the collimation lens 5 is installed between the laser generator 4 and the housing 1, with the laser generator 4
It is parallel；The concavees lens 65 are arranged on the top of the laser pickoff 61, parallel with the collimation lens 5；The PLC controls
System is arranged on the outside of the housing 1, in the offside of the laser generator 4；The laser generator 4, the laser connect
Device 61, the digital display screen 63 is received all to be connected with the controller 62；The digital display screen 63 is installed on the lateral surface of the housing 1.
Specifically, the top for being fixed on the laser pickoff 61 of the concavees lens 65；The housing 1 is provided with vertical
Track, one end of the laser pickoff 61 and the processor 62 is arranged in the track, slided along the track.
Specifically, the housing 1 is columned, a diameter of 15-25MM of the housing 1, the runner 2 it is a diameter of
5-15MM。
Specifically, the laser pickoff 61 includes first component 611 and second component 612；The bottom of first component 611
The both sides in portion are provided with chute 613, and the both sides of the second component 612 are provided with the pulley on pulley 614, the second component 612
614 are located in the chute 613 of the bottom of first component 611.
Specifically, the laser pickoff 61 is provided with opaque cover 63, the opaque cover 63 is provided with slideway, described
The other end of laser pickoff 61 and the processor 62 is located in the slideway, is slided along the slideway；The concavees lens
65 in the inside of the opaque cover.
When in use, the measurement apparatus is powered, for the mixed medicine of different medicines, first respectively by pure water, pure medicine it is mixed
Medicine pours water tank into, is then extracted into centrifugal pump in the runner 2, and the laser that the laser generator 4 is launched is by described
It is parallel after collimation lens 5 to penetrate the runner 2, adjust the position of the concavees lens 65, by the laser after pure water is reflected from
The central point of the concavees lens 65 is passed through；Adjust the length of the laser pickoff 61, it is ensured that laser is passing through pure water and pure medicine
Refraction after can be received by the laser pickoff 61, then along the track on the housing 1 and it is described it is opaque cover 63
On slideway move the laser pickoff 61 and processor 62, excuse me that laser pickoff 61 adjusts receives laser by described
Optimum position, the processor 62 is stored in by distance of the laser after pure water and the refraction of pure medicine on laser pickoff 61
It is interior.When the mixed medicine of same drug various concentrations passes through the runner 2, laser is radiated at the laser pickoff after superrefraction
Position on 61 is different, and position signalling is sent into the processor 62, and the processor 62 then draws mixed medicine by processing
Concentration, and it is included on the digital display screen 63.The processor 63 adjusts the frequency that the laser generator 4 launches laser
Rate, so as to obtain the concentration of the mixed medicine for flowing through the runner 2 of different time, realizes the real-time measurement of mixed concentration.
According to the difference of difference and the measurement accuracy requirement of mixed concentration, the position of the laser pickoff 61 is adjusted up and down
Put, requirement can be reached.As shown in figure 3, when the laser pickoff 61 is moved up, being reflected by the mixed medicine of concentration comparable
Laser reflected by the concavees lens after positional distance on laser pickoff 61 be more closely D1；Under the same conditions, institute is worked as
State after laser pickoff 61 moves down, then the distance of the position on laser refraction to the laser pickoff 61 becomes big, becomes
D2；From D1 to D2, the laser that laser pickoff 61 is sensed is more, so that measurement accuracy is higher.
Mixed medicine will pass through the filtering of screen pack 3 when entering the runner 2, it is possible to increase the purity of mixed medicine, despumation,
Improve accuracy.The laser that the laser generator 4 is sent is after collimation lens 5, by the housing 1 and the folding of solution
Penetrate, projected from the another side of the housing, all emergent rays are all parallel；The quilt after the concavees lens 65 refraction
Laser pickoff 61 receives, and the laser pickoff 61 sends the position signalling of the laser received to the processor 62,
Solution concentration is sent on the digital display screen 63 and shown by calculating by processor 62.Laser is by described recessed
After the refraction of mirror 65, original parallel rays becomes not parallel light, increases the mixed drug solns by two kinds of various concentrations
Distance of the laser on the laser pickoff 61, so as to improve measurement accuracy, increases measurement range after refraction.
Preferred embodiments of the present invention are these are only, therefore the scope that the present invention is implemented can not be limited according to this, i.e., according to the present invention
Equivalence changes and decoration that description is made, should all belong in the range of present invention covering.
