Compared with prior art, a kind of beneficial effect of light reflection mirror turbidity transducer of the invention is: 1, it minimizes,
Turbidity transducer can accomplish that diameter is less than 20CM, facilitate all trades and professions system integration;2, it is easily installed, turbidity transducer carries state
Target G3/4 pipe screw thread, can be directly mounted on pipeline, not need dedicated flow cell;3, save the cost, miniaturization and province's deallocation
Dedicated flow cell, cost are substantially lowered, and are conducive to promote.
Detailed description of the invention
Fig. 1 and Fig. 2 is a kind of structural schematic diagram of light reflection mirror turbidity transducer of the invention;
Fig. 3 is a kind of partial cross-sectional structural diagram of light reflection mirror turbidity transducer of the invention;
Fig. 4 is the partial enlargement structural representation in Fig. 3 at I.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated.
Embodiment
A kind of light reflection mirror turbidity transducer as shown in Figure 1, Figure 2, Figure 3 and Figure 4 by turbidity outer tube 4, and is arranged turbid
Be outside one's consideration the installation screw thread 5 of 4 one end of pipe, and the turbidity circuit board 3 being arranged in turbidity outer tube 4, and through turbidity outer tube 4 and with it is turbid
The data transmission cable 6 that circuit board 3 connects, and the optical path guide support 2 being arranged in 4 one end of turbidity outer tube are spent, and setting exists
Optical path guide support 2 and the infrared laser pipe 7 connecting with turbidity circuit board 3, silicon light-emitting tube 8, and setting guide branch in optical path
Reflection tube 9, transmitting tube 10 on frame 2, and 4 one end of turbidity outer tube is set and is located at the optical frames in 2 outside of optical path guide support
Piece 1, and the plastics optical path 11 being arranged on optical path guide support 2, and be arranged on plastics optical path frame 11 the first reflecting mirror 12,
Second reflecting mirror 13.
It is further preferred that the optical mirror slip 1 is sapphire optical eyeglass, sapphire optical eyeglass has very high hard
Prevented also from being worn measurement accuracy can be improved in degree and light transmittance, it is loaded on to the front end of sensor, is contacted with liquid.Institute
Infrared laser pipe 7 is stated using the 850nm specification of diameter 3mm, 15 degree of light emitting angle <, such as model SFH4350, is declined to reduce
Subtract, using pulsed excitation, excitation current < 100Ma.
The reception pipe of the silicon light-emitting tube 8 uses diameter for 5mm specification, perceives wave-length coverage 300-1100nm, such as type
Number be OSIPIN-3CDP silicon photoreceptor.First reflecting mirror 12, the second reflecting mirror 13 specification be respectively 3*6*
0.55mm, mounted in the optical path frame 11 of plastics, reflection wavelength needs to cover the wavelength of red place's laser tube, and the light to guarantee laser tube is most
Small loss is measured, reflectivity is greater than 92%, and reflecting mirror needs two panels in 11 fixed structure of optical path frame of symmetrical plastics.
First reflecting mirror 12 is placed on the light of the plastics of one side by the light reflection mirror turbidity transducer of this structure, when assembly first
It in 11 fixed structure of road frame, is fixed with glue in reverse side, then the second reflecting mirror 13 is placed on to the optical path frame 11 of the plastics of one side, use glue
It is fixed in reverse side, before 11 fixed structure of optical path frame of another side plastics is pressed together in 11 structure of optical path frame of the plastics of one side,
Sapphire optical eyeglass and sensor front end face are carried out gluing again, sealing is paid attention to, infrared laser pipe and silicon photoreceptor is consolidated
It due on circuit board, then docks with 11 structure of optical path frame of plastics, is fixed with glue, after last glue is dry, mounted in tubulose
In shell, G3/4 screw thread, gluing are loaded onto.
Two panels reflecting mirror is attached separately to turbidity transducer front end, utilizes two by the light reflection mirror turbidity transducer of this structure
A plastic construction welds infrared laser pipe and silicon light receiving tube on circuit boards, keeping parallelism, respectively to fix its position
With two panels reflecting mirror at 45 degree of angles, laser tube issues the infrared light of 850nm, is transmitted by the hole that two panels plastic construction is stitched together
On the mirror, by the reflection of reflecting mirror, sapphire eyeglass across front end is injected in liquid, and suspended substance in liquid is by light
