Abstract
The invention belongs to the technical field of particle detection, and relates to a dynamics testing device for detecting response behavior of pH (potential of hydrogen) oscillation of particle. Thedynamics testing device comprises a testing device body, wherein the testing device body comprises a heat insulation sleeve and a reactor; the reactor is fixedly arranged in the heat insulation sleeve; a circulating water inlet is arranged at the upper end of the left side surface of the heat insulation sleeve, and a circulating water outlet is arranged at the lower end of the right side surface of the heat insulation sleeve; a light source incident passage is arranged in the middle part of the left side surface of the reactor, and penetrates through the heat insulation sleeve; a laser focusing lens is arranged at the back end of the light source incident passage; a reaction liquid inlet passage and a reaction liquid outlet passage are respectively arranged at the left side surface and upper side surface of the reactor and penetrate through the heat insulation sleeve; an observing passage is arranged at one side of the heat insulation sleeve, and is vertical to the horizontal directionof the light source incident passage. The dynamics testing device has the advantages that a continuous flowing stirring reactor is built; by enabling the material to continuously flow in and flow out, the reaction is stably performed for a long time, and the dynamics behavior of the response reaction of the pH oscillation of the particle can be monitored in real time.
Description
technical field [0001] The invention belongs to the technical field of particle detection, and relates to a kinetic testing device for detecting the pH oscillation response behavior of particles. Background technique [0002] Many important characteristics of granular materials are determined by the average particle size and particle size distribution parameters of the particles. With the development of science and technology, particle size measurement technology has received widespread attention and has gradually developed into an important branch of modern metrology. Conventionally, in order to express the size of particles with one-dimensional parameters, the concept of equivalent spherical diameter is introduced in the usual particle size measurement methods, that is, the measurement model is established on the basis that the measured particles are equivalent to ideal spherical particles. Particle measurement methods include screening method, microscopy method, sedimenta...
