Description

technical field [0001] The invention relates to a machine vision suspension turbidity detection device and a detection method, belonging to the field of detection instrument development, in particular to a suspension turbidity detection device and method using centrifugal and machine vision technologies. Background technique [0002] In some mixtures, the substance dispersed in the liquid is not dissolved but exists as fine solid particles. When the outside world stops exerting influence on the mixture (including shaking, shaking and stirring, etc.), the dispersed solid particles will settle under the action of gravity and gradually form a stable particle deposition layer at the bottom of the liquid. We call this heterogeneous and inhomogeneous , An unstable mixture is called a suspension. Among them, the solid particles are called dispersoids, and the fluid in which the solid particles are dispersed is called a dispersant. Generally speaking, water is the most common disp...

Problems solved by technology

[0009] Although the above-mentioned patents have improved the measurement accuracy to a certain extent, the core detection principle and technical solution still adopt the traditional optical detection method, and the mechanical behavior of particles such as agglomeration and sedimentation during the detection operation is still unavoidable, so the inherent shortcomings of the aforementioned optical detection method not completely resolved
