Abstract

The invention provides a semi-microphase balance system controller, which mainly includes a temperature detection circuit, a temperature setting circuit, a photoelectric coupling circuit, a heating drive circuit, a stirring motor drive circuit, an A / D voltage acquisition circuit, and a liquid crystal display interface circuits and core processing unit circuits. The invention obtains the actual temperature in the reaction container of the semi-micro phase balance system through the temperature detection circuit, then compares the temperature setting value with the actual temperature value, and then uses the control algorithm to obtain the control amount of the heating drive circuit; the controller can be well It satisfies the requirements of the semi-micro phase equilibrium system reaction vessel on the accuracy and uniformity of the ambient temperature, realizes the digitalization and automation of the measurement and control of the semi-micro phase equilibrium reaction vessel, and ensures the accuracy and stability of the reaction environment parameters.

Description

technical field [0001] The invention relates to a semi-trace phase balance and extraction balance experimental device, in particular to a semi-trace phase balance system controller. Background technique [0002] Semi-microanalysis is a relatively common analysis method, which is between microanalysis and constant analysis. From the perspective of protecting the living environment of human beings and saving energy and resources, chemists are required to design experiments and experimental techniques with the concept of green chemistry. In the process of separation and purification of rare, dilute and precious metals, the phase equilibrium of the solution and the equilibrium of multiphase extraction are often encountered, and the semi-micro analysis method is often used in chemical experiments. [0003] At present, the domestic semi-microphase equilibrium chemical reaction device is composed of organic glass carrier, micro AC motor, self-made balance tube, micro relay, thermo...
