Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
See Fig. 1 to Fig. 3, a kind of online turbidimeter with flow control of the present invention, comprising: top cover 1, folliculus mechanism 2, photoelectric detection mechanism 3, sample flow cell 4, flow controller 5 and bottom 6.
Water sample to be detected flows into from water inlet 7, enters folliculus mechanism after being adjusted to suitable flow via flow controller 5.As a kind of concrete structure, flow controller 5 is a vertically disposed tapered tube, and tapered tube small end is held greatly upwards downwards and had a float that can fluctuate in tapered tube.When water sample flows through tapered tube from bottom to top, between float is upper and lower, produce pressure reduction, float rises under this differential pressure effect.The power risen when making float and the gravity suffered by float, buoyancy and viscous force three make a concerted effort equal time, float is in equilibrium position, namely can calculate the flow value of current water sample according to the altitude gauge of float.Preferably, flow controller 5 is preferably with a display panel, reads water flow intuitively in real time to facilitate user.
The present invention is that employing 90 ° of light scattering methods detect water turbidity, so, bubble in water sample is very large on testing result impact, in order to address this problem, water sample is in the process flowing through folliculus mechanism 2, by buoyancy froth breaking method principle, filtering bubble is to get rid of the impact of bubble on Turbidity measurement result.
Photoelectric detection mechanism 3 is arranged in sample flow cell 4, measure the turbidity of water by photoelectric sensing mode and current turbidity can be shown in real time, based on 90 ° of light scattering methods, water turbidity is detected, its Cleaning Principle is: first light expelling plate launches modulated light signal by trigger actuation light source, vertically inject in sample flow cell 4, and a highly sensitive photodetector detection scattered light intensity is placed in 90 ° of directions, under low turbidity, intensity and the turbidity of 90 ° of direction scattered lights are linear, therefore can calculate water sample turbidity value.The structure of photoelectric detection mechanism 3 of the present invention is see Fig. 4, comprise main body rack 14, be installed on the reference detector 13 in main body rack 14 and heating radiator 12, at heating radiator 12 top, one fixed head 34 is installed, underwater detectoscope 17 is installed bottom main body rack 14, when carrying out Turbidity measurement, underwater detectoscope 17 is immersed in water sample to be measured, stable rising water stage can be obtained like this in sample flow cell 4, avoid water inlet 7 up time shallow spray causing or enter water whirlpool, cause the refraction of incident light in water to detect scattered light to impact, and then guarantee the accuracy of testing result.In addition, be also provided with light room cover plate 15 and light barrier 16 in the bottom of main body rack 14, thus avoid non-90 degree scattered light to the interference of measurement result, improve the accuracy of testing result further.
Conveniently discharge the water in sample flow cell 4, bottom sample flow cell 4, be provided with a freeing port 8.Further, in order to avoid the excessive draining caused of the too high water yield of water level is too late, bottom sample flow cell 4, be also provided with a gap 9, to prevent emergency situations to the infringement of equipment.
In addition, bottom 6 also forms a sewage draining exit 10 be communicated with described sample flow cell 4, the height of sewage draining exit 10, lower than freeing port 8, to facilitate the sediment in periodic cleaning sample flow cell 4, thus ensures the accuracy of measurement result.
More than show and describe ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
