Multi-channel fluid precise and uniform mixing system and mixing method thereof

Abstract

The invention provides a multichannel fluid precision uniform mixing system and a mixing method thereof. The mixing system comprises a centrifugal oscillation device and a plurality of fluid precisiondistribution devices, wherein the mixing system adjusts the actuation stroke and movement distance through a stepping motor, so that which stroke of a flexible rubber diaphragm according to the amount given by the stepping motor is determined, and the fluid flow is accurately controlled; due to the fact that control is achieved through the motor, the liquid inlet amount and the liquid outlet amount can be accurately controlled through the feedback system, and the amount of obtained liquid can be calculated according to the distance given by the stepping motor. The magnetic field is changed bychanging the current passing through the magnet exciting coil, and then the variable quantity of the magnetic control shape memory alloy is changed; therefore, as long as the deformation quantity ofthe actuation is changed, the magnitude of the actuation can be changed, the magnitude of the actuation can be changed, and the control over the fluid transportation quantity can be achieved. Finally,the fluid flows into the test tube through a liquid outlet of the tube joint after flowing out, and rotates and revolves to realize stirring, so that precise mixing of the fluid is realized.

Description

technical field [0001] The invention belongs to the technical field of fluid mixing, and in particular relates to a multi-channel fluid precise uniform mixing system and a mixing method thereof. Background technique [0002] It is difficult for the fluid distribution devices in the prior art to realize the flow control of the precise fluid, only the general control, and cannot realize the transportation of the precise amount; and most of the fluid distribution devices in the prior art are driven by the crank rocker and the hydraulic pneumatic pump. , need auxiliary system, complex structure and large volume. [0003] The existing fluid stirring device usually stirs the fluid by means of a reactor and a stirring rod, which is bulky and has a complex structure. The stirring rod is connected with a bearing, and the long service life of the fluid stirring device will cause the bearing to wear out, causing the toxic metal Substance has entered the fluid, contaminating the fluid....
