Abstract
The invention discloses a device for absorbing transmission light during turbidity measurement. The device comprises a light inlet hole, a primary reflector, a secondary reflector, a light absorption trap and a fixing hole. The device is fixed to the plane perpendicular to transmission light penetrating through a sample through the fixing hole in a base plate. The transmission light irradiates on the primary reflector through the light inlet hole, and a 45-degree angle is formed between the transmission light and the primary reflector. After being reflected by the primary reflector, the transmission light irradiates on the secondary reflector, and a right angle is formed between the surface of the secondary reflector and the surface of the primary reflector. The transmission light is reflected by the secondary reflector into the light absorption trap in isolated space and then absorbed by the light absorption trap.
Description
Technical field
The present invention relates to a kind of device of light through sample during absorbing Turbidity measurement, in particular,
The present invention relates to a kind of during scattering-light turbidity detects, eliminate the veiling glare produced by the light through sample to inspection
Survey the device of precision impact.
Background technology
Turbidity is also referred to as turbidity, is used to reflect float in water, such as silt, clay, algae, organic substance and its
One water quality parameter of his microbial organisms content.Turbidity is sense organ the most directly the evaluating water quality of people, is one
Critically important water quality parameter.
Turbidity measurement has used scattering of light theoretical, i.e. when the particle in solution runs into light beam, it will to light
Produce scattering and Absorption, between intensity and the turbidity of solution of scattered light wherein at a right angle with incident illumination centrage, become line
Sexual relationship, but the veiling glare during detection will affect this linear relationship, and the accuracy of detection is produced impact.
Veiling glare refers to that being not due to sample scattering reason arrives the light of detector, and its source includes:
1) sample cell is undesirable and the scratch on sample cell surface；
2) reflection within optical system, the pollution of optics；
3) there is dust on sample cell；
Still having the highest intensity after the light beam of Turbidity measurement passes through sample cell, this transmission light occurs in instrument internal
Multiple reflections, produces a large amount of veiling glare, the measurement of interference turbidity.
During solution Turbidity measurement, the method for transmission light interference mainly has two kinds at present: one is to be irradiated to by transmission light
Plane on coat black light-absorbing material, but light absorbent can only sponge fraction light, and most transmission light still can produce
Raw reflection.And the light absorbent of some online turbidity analyser is arranged on bottom instrument, in solution, the granule of sedimentation can cover
On light absorbent, the effect of extinction is made to have a greatly reduced quality；Another method is to make transmission light be irradiated to an inclined-plane, by transmission
Luminous reflectance is to other directions, but not by transmission photocontrol in the space isolated with photodetector, and still can be to the inspection of turbidity
Survey and produce impact.
Summary of the invention
Problem to be solved by this invention, it is simply that overcome the defect of above-mentioned prior art, and provide for this one to be used for disappearing
The device of transmission light interference during detecting except scattering-light turbidity.
Technical scheme is as follows:
A kind of device of transmission light during absorbing Turbidity measurement, including incident light hole, primary event mirror, secondary reflection
Mirror, extinction trap and fixing hole.Described device is fixed on vertical with the transmission light through sample by the fixing hole on base plate
In plane, transmission light is radiated on primary event mirror by incident light hole, and by the reflection of primary event mirror, incident illumination is radiated at
On secondary reflection mirror, secondary reflection mirror is by the extinction trap of transmission luminous reflectance to insulating space, and incident illumination is by described extinction trap
Absorb.Incident illumination through two secondary reflections laggard enter with instrument sensing chamber isolation space, without interference with the measurement of turbidity.
The present invention, compared to prior art, has the advantages that.
1) using direct reflection incident illumination, reflection efficiency is high, and good directionality, the veiling glare of generation is few；
2) incident illumination is reflected to insulating space, and is completely absorbed, and will not produce reflection light and the scattering affecting Turbidity measurement
Light.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention.
Labelling in figure: 1 incident light hole 2 primary event mirror 3 secondary reflection mirror 4 extinction trap 5 fixing hole
6 insulating spaces

To in 45 degree of angles, the minute surface of secondary reflection mirror (3) is rectangular with the minute surface of primary event mirror (2), and incident illumination is through two secondary reflections
Rear entrance insulating space (6), the extinction trap (4) being isolated in space (6) is absorbed.Described bottom of device has two fixing holes
(5).
Described reflecting mirror (5) uses glass mirror.
Described extinction trap (4) uses light absorbent to make.
Above by reference to drawings and Examples, present invention device of transmission light during absorbing Turbidity measurement is carried out
Schematic description, this description is the most restricted.Those of ordinary skill in the art will be understood that in actual applications, in order to suitable
Needing together in certain, in the present invention, the set-up mode of certain parts is likely to occur some change, and other staff are in the present invention
Enlightenment under be likely to make similar Design.Special needs to be pointed out is, without departing from the design aim of the present invention, all aobvious
And the change being clear to and similar Design, within being all contained in protection scope of the present invention.
