In addition, for the solution in the cuvette, adopt the magnetic stirrer technology, but not the existing technology that stirs from cuvette bottom injection air, the mixing effect that it can obtain is avoided measurement result is produced unfavorable interference.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
The structural representation of the embodiment of Fig. 1 photoelectric detection system of the present invention.
Fig. 2 is index path of the present invention.
Embodiment
Such as Fig. 1 and 2, the embodiment of the photoelectric detection system that the present invention proposes mainly comprises: bearing 1, cuvette 2, light source 3, receiver 4 and magnetic stirrer 7.
Wherein, bearing 1 and cuvette 2 all adopt integral structure, to strengthen steadiness.Cuvette 2 adopts the mode that is threaded to be fixed on the centre of bearing 1, for example: cuvette 2 is fixed by screws on the bearing 1, can be in advance at the one or more mounting holes of bearing 1 design during specific implementation, then by screw cuvette 2 is fixed on this mounting hole, to realize cuvette 2 is fixed on the centre of bearing 1.The benefit of the mode that employing is threaded is: when guaranteeing the constant intensity of cuvette 2, conveniently cuvette 2 is disassembled from bearing 1, to make things convenient for contrast colors ware 2 and to clean and maintenance.
Wherein, cuvette 2 has overflow vent 8 and a sewage draining exit, and this overflow vent 8 and sewage draining exit are used for connecting with external connecting pipe all with connecing mouth.By overflow vent 8, solution excessive in the cuvette 2 can flow out thus, and the internal diameter of this overflow vent 8 can be arranged on about 7.5 to 8.5mm, to strengthen the overflow effect.This sewage outfalls setting is at the lowermost end of cuvette 2 inner chambers, to guarantee arranging up hill and dale waste liquid in the light cuvette 2 by sewage draining exit.Further, also have a cover plate 6 directly over cuvette 2, this cover plate can be fastened on the cuvette, with the opening of sealing cuvette.Has the fixing injection port of sample water sample feeding pipe and reagent sample feeding pipe on the cover plate 6; By injection port, water and reagent etc. can flow in the cuvette 2, is mixed into solution.Preferably, cuvette 2 can be quartz glass material cuvette, this quartz glass can be selected the quartz glass with following characteristic: hardness is large, high temperature resistant, expansion coefficient is low, resistance to heat shocks, chemical stability and general acid had preferably acid resistance etc., employing has the quartz glass cuvette of above-mentioned characteristic, can ensure monochromatic transmissivity and the stability of the parallel plate that sees through the cuvette both sides.
Wherein, light source 3 and receiver 4 are fixed on the bearing 1, are positioned at the both sides of cuvette 2.Particularly, have a light source mounting hole and receiver mounting hole on the bearing 1, this light source mounting hole and receiver mounting hole are coaxial, and light source 3 is crimped in the light source mounting hole by light source fixing part, and receiver 4 is crimped in the receiver mounting hole by the receiver fixture; Because light source mounting hole and receiver mounting hole are coaxial, therefore by after the above-mentioned mounting means, can guarantee that the monochromatic light of light source 3 ejaculations is by behind the cuvette 2, collimation and the stability of the light path that received device 4 receives, namely guarantee collimation and the stability of light path, thereby improve the accuracy of photoelectric colorimetry testing result.Further, above-mentioned photoelectric detection system can also comprise: O type circle, in light source mounting hole and receiver mounting hole, be provided with groove, O type circle is installed in the groove of light source fixing part and receiver fixture, with light source, receiver and cuvette sealing, to get rid of the possibility of knot mist, reduce external environment condition to the interference of measurement result.
Wherein, magnetic stirrer 7, the solution that is used for contrast colors ware 2 stirs, and this magnetic stirrer 7 is fixed on bearing 1, can be positioned near position, 5mm place, cuvette 2 below.Particularly, magnetic stirrer 7 comprises: direct current motor 71, magnet 72 and stirrer 73.Wherein, direct current motor 71 and magnet 72(have two) be fixed on the bottom of bearing 1, magnet 72 is positioned at the output terminal of direct current motor 71, and stirrer 73 places cuvette 2.When direct current motor 71 work, its output terminal drives magnet 72 rotations, realizes stirring under the effect in magnetic field.Preferably, stirrer 73 adopts the anticorrosive property material to make, to increase its antiseptic power.The benefit of above-mentioned employing magnetic stirring is: tradition passes into the mode that air stirs to cuvette 2 bottoms, easily cause the solution in the cuvette 2 to be splashed on the wall of cuvette 2 owing to bubble breaks, also easily cause solution to be back in the air leading-in conduit, the appearance of these situations all can have a strong impact on stability and the accuracy of apparatus measures.Adopt the magnetic stirring technology, drive two ends magnet rotation by direct current motor, realizing stirrer 73 uniform rotation in cuvette 2 under the drive in magnetic field, splashing or suck-back of solution can not appear, when reaching mixing effect well, measurement result is not produced unfavorable interference, in the accuracy that guarantees measurement result.
