Abstract

The invention relates to a device and a method for detecting fluid magnetic particles. The device comprises an imaging module, an adsorption module, a control module, a light transmission piece and an image processing module, wherein the imaging module, the adsorption module and the light transmission piece are arranged on the same side of a runner; the adsorption module is electrically connected with the control module; the light transmission piece is fixed on the upper surface of the runner and is positioned in the center of the light path of the imaging module; the light transmission piece is positioned in a magnetic field generated by electrifying the adsorption module; the particles are adsorbed to the lower side of the light transmission piece by virtue of the adsorption module; the image processing module is respectively and electrically connected with the imaging module and the control module; the particle image signal output by the imaging module is processed and then uploaded to the control module; and the image signal is subjected to image analyzing and processing by virtue of the control module, so as to acquire the physical property data of the particles. The influence of bubbles in fluid on the imaging of the magnetic particles is eliminated, the magnetic particles in the fluid are detected, and the number, shape, texture and size of the magnetic particles in the fluid can be obtained.

Description

technical field [0001] The invention relates to the field of equipment status detection and analysis, in particular to a device and method for detecting fluid magnetic particles based on magnetic particle imaging in fluid to obtain physical characteristics of magnetic particles. Background technique [0002] The technical principle of detecting fluid magnetic particles is to use inductive excitation to generate magnetic force, absorb magnetic particles in the fluid, and perform particle imaging processing in order to detect the physical characteristics of particles such as size, concentration, shape, color, and texture. [0003] In some existing magnetic particle detection devices, such as the Chinese invention patent application with the publication number CN103983543A, the lens and the adsorption parts are respectively arranged on both sides of the oil flow channel, and the focus range is only 1.8 times, which results in In the case of oil particles, due to the refraction ...
