Material transmission caused by the strong mixing of vortex acts on much bigger more than molecular motion, therefore eddy diffusivity
Flux much larger than molecule spread.Identical with molecule diffusion, vortex expands calculation speed and is directly proportional to concentration gradient, and its proportionality coefficient is
Expand for vortex and calculate coefficient.It is not Physical Constants that vortex, which expands calculation coefficient, and its size is relevant with the less turbulence of fluid.Present invention dress
Putting makes specimen cup by intervals alternating clockwise and rotates at a high speed counterclockwise, the flow direction of fluid in cup is regularly cut
Become, so as to produce different vortex changes, increase the less turbulence of fluid, to accelerate the diffusion of the solute in liquid, to accelerate
Dissolving, above speed-change process will be realized by the combination of direct current adjustable speed motor and controller.
In apparatus of the present invention, controller, for controlling motor, effect has two：1. change by set time interval
Become the direction for the direct current for being output to motor, to reach the purpose being rotated both clockwise and counterclockwise；2. it is used to adjust output
Voltage swing, to control the rotating speed of specimen cup.
Compared with prior art, the invention has the characteristics that：
1) solvent used in the processing of a small amount of sample, each specimen cup can be used for be less than 0.5ml；
2) only has turning effort in course of dissolution, it is ensured that the stabilization of the structure of matter；
3) driven pulley, cup and spring chuck integration, convenient handling, number dress sample on demand；
4) specimen cup of different size can be used, it is only necessary to which the size for adjusting turn is fixed, easy to loading and unloading；
5) simple in construction, simple operation, security and stability is good, and specimen cup can be made to carry out the constantly alternate clockwise and inverse time
Pin rotates at a high speed, produces different vortex changes, accelerates the dissolving of solute, in the case where ensureing the stability of solute, significantly
Dissolved efficiency is improved, with good application prospect.
