Embodiment Construction

[0010] In the figure, the light source generating device ② is placed on the outside of the liquid container ①, and is close to the container wall; the photoelectric receiving device ③ is placed on the other side of the liquid container ①, and is close to the container wall; the light source generating device ② and the photoelectric receiving device ③ Maintain a horizontal straight line relationship, and the line connecting the centers of ② and ③ passes through the horizontal midpoint of the container. When testing, first perform zero point calibration: that is, use pure water as the detection object, and obtain the reference parameters on the photoelectric receiving device through light transmission. Then use the same light source to transmit the mixed liquid under test in the same container. After processing by the circuit and calculation software of the photoelectric receiving device, the degree of transparency of the mixed liquid or the proportion of visible impurities can ...

Abstract

The invention discloses a noncontact automatic detection for detecting transparency of mixed liquid such as turbid liquid, emulsified liquid and the like. The noncontact automatic detection method comprises the steps of: generating one group of plane visible light and black light, and the plane visible light and the black light pass through the outer side of a transparent container and horizontally irradiates the mixed liquid to be mixed; the light penetrates through the mixed liquid to lose partial energy, the other part of light arrives at a photoelectric receiving device at the other opposite outer side of the transparent container and a photoelectric converter in the photoelectric receiving device generates a photovoltaic electric signal, the photovoltaic electric signal is processed through a circuit and a computing program, thus a numerical value of absorbing light energy of the mixed liquid to be measured can be obtained, thus the transparency of the mixed liquid is determined.

Description

Technical field: [0001] The invention relates to a non-contact automatic detection technology based on photoelectricity, which is especially suitable for the detection of the demulsification resistance of petrochemical liquids and the turbidity of the liquids. Background technique: [0002] So far, in the detection of demulsibility similar to petroleum and synthetic fluids, the measurement of liquid transparency is firstly the measurement method of direct observation with human eyes and subjective judgment; the second is the measurement method of drip sampling analysis. The disadvantages of the two methods are that human visual inspection is subjective and arbitrary, which affects the objective accuracy of the results, and the limitations of samples during drip sampling analysis affect the objective consistency of the results. Invention content: [0003] The technical problem solved by the invention is to propose a non-contact, objective and accurate automatic detection me...
