Description
Technical field
The utility model relates to a kind of detector, particularly a kind of liquid turbidity detector.
Background technology
In people life and producing, conventional turbidity characterizes the cleannes of liquid, and the turbidity of water is that silt, clay, the fine suspended material such as organic matter and inorganic matter, soluble coloured organic compound and planktonic organism and other microorganism form. These suspension mass-energy absorption bacterium and viruses, thus the low sterilization that is conducive to water of turbidity, on guaranteeing that water quality index has epochmaking impact. Turbidity is measured by liquid turbidity detector, its operation principle is that nephelometer emits beam, make it through one section of sample, and detect from being the direction of 90 ° with incident light the scattered light that the particle in water produces, this scattered light measuring method is called scattering method. And laser liquid turbidity detector is to adopt laser as light source, because its light beam is the single product light beam through close adjustment, therefore veiling glare has been eliminated, and precision is higher. Existing laser liquid turbidity detector complex structure, is applicable to the laboratory of the industries such as waterworks, sewage treatment plant, wastewater treatment monitoring etc. But actual conditions, need to carry out turbidity detection to outdoor environments such as rivers,lakes and seas, this instrument uses and is inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of laser liquid turbidity detector, and it comprises Handheld Division, display screen, processing unit, and described display screen is located at the end of Handheld Division; Inside, described Handheld Division is provided with the detection cell for holding testing liquid, detection cell front is provided with collimation lens, and collimation lens front is provided with laser tube, is provided with a through hole in the middle of collimation lens and laser tube, detection cell rear is provided with optical filter, is provided with photoelectric receiving tube after optical filter; Described photoelectric receiving tube receives after signal, is transferred to processing unit, and processing unit transfers signals on display screen.
Further, described optical filter rear, photoelectric receiving tube front are provided with convergent lens. The effect of convergent lens is to strengthen the signal that photoelectric receiving tube receives.
Further, the length from collimation lens to optical filter is 70mm.
Further, Handheld Division is also provided with cushion pad away from the end of display screen.
Further, described cushion pad is quality of rubber materials.
This laser liquid turbidity of the utility model detector is light, portable, goes for outdoor environment and carries out conveniently turbidimetry; Adopt laser tube as light source, light source is single, there is no veiling glare, has simplified the structure of light source.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to accompanying drawing 1, this laser liquid turbidity of the utility model detector, it comprises Handheld Division 1, display screen 2, processing unit, display screen 2 is located at the end of Handheld Division 1; 1 inside, Handheld Division is provided with the detection cell 3 for holding testing liquid, detection cell 3 fronts are provided with collimation lens 4, and collimation lens 4 fronts are provided with laser tube 5, collimation lens 4 and the middle through hole 6 that is provided with of laser tube 5, detection cell 3 rears are provided with optical filter 7, are provided with photoelectric receiving tube 8 after optical filter 7; Photoelectric receiving tube 8 receives after signal, is transferred to processing unit, and processing unit transfers signals on display screen 2. Optical filter 7 rears, photoelectric receiving tube 8 fronts are provided with convergent lens 9. The effect of convergent lens 9 is to strengthen the signal that photoelectric receiving tube receives. Length from collimation lens 4 to optical filter 7 is 70mm. Handheld Division 1 is also provided with cushion pad 10 away from the end of display screen, and this cushion pad is quality of rubber materials.
Specific works step is, testing liquid enters in detection cell 3, and laser tube 5 sends LASER Light Source, light source becomes collimated light beam after through hole 6 and collimation lens 4, and this light beam is through testing liquid, more after filtration after mating plate 7, after convex lens 9, received by photoelectric receiving tube 8. Photoelectric receiving tube 8 has received signal, is transferred to processing unit, and photosignal is converted into the signal of telecommunication by processing unit, finally reads the turbidity value of this liquid by display screen.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model. All any amendments of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model within spirit of the present utility model and principle.
