The phase-stable detecting device has the main improvements that a defoaming chamber longitudinally partitioned by a trough plate is arranged in the measuring chamber; the upper part of the trough plate is provided with a water outlet filter screen; the photoelectric measurement detecting rod downwards extends into the measuring chamber from an upper end face of the shell; and the lower end of the photoelectric measurement detecting rod is lower than the lower end face of the water outlet filter screen. In the phase-stable detecting device, big bubbles are filtered off by the filter screen, and sample liquid enters from the upper part of the measuring chamber so as to limit small bubbles carried in the sample liquid to moving above a probe without passing through the probe, so that the measurement is not influenced by the small bubbles. Not only is the measuring accuracy greatly improved but also the structure is simple, the manufacturing is easy and the cost is low.
Description
Technical field
The utility model relates to a kind of online turbidimetric apparatus, and specifically, it is a kind of steady phase sniffer of online turbidimetric apparatus.
Background technology
Turbidity is meant the impurity such as suspension, colloid thing, planktonic organism and microorganism that contain different sizes, proportion, form in the water body, and these impurity can form scattering and absorption to light, therefore, utilize the light reaction principle can measure the turbidity of water body.In the prior art, on-line measurement is generally adopted in the measurement of various source qualities, promptly taken a sample from the water source, after the measurement by measurement mechanism, draw in the backwater source again, the sample liquid recycle stream is moving, thereby realizes real-time on-line measurement.The sniffer of the online turbidimetric apparatus of tradition as shown in Figure 2, it generally is made up of sampling liquid circulation groove 100 and the photoelectric measurement probe 200 that is installed on this sampling liquid circulation groove, and the lower end of described photoelectric measurement probe is provided with a luminescence unit and a reflected light receiving element.During work, the photoelectric measurement probe is sent into subsequent process circuit and is handled according to receiving the electric signal that catoptrical power provides corresponding size.Yet, in measuring process, the adhering to of suspension, the floating of underwater bubble all can produce considerable influence to measuring accuracy in the water, and the suspension in the water can clean eliminating by the cleaning apparatus for self that is located at before the sniffer, and underwater bubble is difficult to remove with isolated plant.At present, domestic water treatment all will be passed through preprocessing process such as dosing, clarification, filtration, can continue to produce bubble in this process, and as effectively not advancing processing, turbidity measurement often takes place to jump and changes, and has a strong impact on measuring accuracy.
Chinese patent ZL01210768.9 provides " a kind of online turbidimetry sensor ", this patent is provided with a deaeration chamber, in this deaeration chamber, be provided with the inclination diaphragm plate of two upper and lower layouts, drainpipe is housed on the diaphragm plate, after sample liquid enters the deaeration chamber, along upper and lower two inclination diaphragm plate from top to down S shapes walking, thereby make the bubble floating in the water and discharge from drainpipe.This deaeration mode can remove the air pocket in the water, and some tiny bubbles still are difficult to remove, and they are still carried into measuring chamber by sample liquid.Enter from the measuring chamber bottom owing to enter the sample liquid of measuring chamber, so the minute bubbles in the water can float naturally, again because measurement window is positioned at the measuring chamber middle part, so minute bubbles can pass through measurement window in floating-upward process, thereby influence is measured.Moreover this deaeration mode also makes structure comparatively complicated.
The utility model content
The purpose of this utility model is at the problem in the prior art, and the steady phase sniffer of the online turbidimetric apparatus that a kind of defoaming effect is good, measuring accuracy is high, simple in structure is provided.
For achieving the above object, the technical solution of the utility model is as follows:
It comprises a shell, the inner chamber of this shell is a measuring chamber, on this shell, be provided with a water inlet pipe and a rising pipe, be provided with a blow-off pipe in the bottom of described shell, it also comprises a photoelectric measurement feeler lever, its improvements are: be provided with a defoaming compartment that is vertically divided into trough plate in described measuring chamber, be provided with out water screen on the top of described trough plate; Described water inlet pipe communicates with described defoaming compartment, and this water inlet pipe is located at the bottom of defoaming compartment, described rising pipe communicates with measuring chamber, and this rising pipe is located at the top of measuring chamber, described photoelectric measurement feeler lever stretches into the measuring chamber downwards from the upper head plate of shell, and the upper end of this photoelectric measurement feeler lever is fixed on the upper head plate of shell, and its lower end is lower than the lower surface of water screen.
The further improved technical scheme of the utility model is as follows:
Described trough plate is the triangular groove shape plate.
By technique scheme as can be seen, the utility model filters out air pocket with filter screen, and sample liquid is entered from measuring chamber top, the minute bubbles that carry in the restriction sample liquid are movable on probe, without probe, make measurement not be subjected to the influence of minute bubbles, not only improved measuring accuracy greatly, but also simple in structure, making is easy, cost is low.

Embodiment
Referring to Fig. 1, it comprises a shell 1, is provided with a water inlet pipe 2 and a rising pipe 3 on this shell, is provided with a blow-off pipe 4 in the bottom of described shell; It also comprises an electro optical measurement feeler lever 5; The inner chamber 6 of described shell is a measuring chamber, in this measuring chamber, be provided with a defoaming compartment 8 that is vertically divided into trough plate 7, described trough plate 7 can adopt triangular groove shape plate, semicircle trough plate and square trough plate etc., and this example adopts the triangular groove shape plate, helps the water in the defoaming compartment 8 is derived; Be provided with out water screen 9 on the top of described trough plate 7; Described water inlet pipe 2 communicates with this defoaming compartment 8, and this water inlet pipe is located at the bottom of defoaming compartment 8, help bubble floating and overflow from filter screen with sample liquid, described rising pipe 3 communicates with measuring chamber 6, and this rising pipe 3 is installed in the top of measuring chamber 6, helps the sample liquid discharge that measuring chamber carries minute bubbles at the middle and upper levels; Described photoelectric measurement feeler lever 5 stretches into downwards the measuring chamber 6 from the shell upper head plate, and the upper end of this photoelectric measurement feeler lever is fixed on the upper head plate of shell, and its lower end is lower than the lower surface of water screen 9, to avoid carrying the upper strata sample liquid of minute bubbles.
The course of work of this device is: tested sample liquid enters defoaming compartment 8 by water inlet pipe 2 earlier, bubble in the water floats naturally, when the water surface in the defoaming compartment surpasses water screen 9, nature enters measuring chamber 6 from going out water screen 9 and overflowing, the sample liquid that enters measuring chamber through the filtration that goes out water screen 9 after, air pocket wherein is eliminated, tiny bubble still is carried into measuring chamber, and swim in the upper strata of measuring chamber sample liquid, when the sample liquid liquid level in the measuring chamber surpassed rising pipe, sample liquid nature was discharged along rising pipe 3.In the flow process of above-mentioned detected sample liquid,, only, therefore, do not influence measurement in the top of photoelectric measurement feeler lever 5 (promptly more than the probe) activity though tiny bubble is brought into measuring chamber 6.
