Description

Liquid mixing reactor Technical Field The utility model relates to a liquid mixing reactor, in particular to an integrated reactor for quickly and uniformly mixing two groups of liquid reactants after independent temperature control, belonging to a chemical experimental instrument. Background The measurement of the chemical reaction rate and the activation energy is a classical chemical experiment commonly opened in domestic universities, the experiment aims at the reaction of ammonium persulfate solution and potassium iodide solution, two groups of liquid reactants are respectively heated or cooled to a specific temperature and then mixed for reaction, the reaction time is recorded, and the results of the reaction rate, the activation energy and the like are obtained according to experimental data. The conventional procedure for this experiment generally involves placing ① two sets of liquid reactants in two containers (e.g., beakers), respectively, ② placing the containers containing the reactants in a warm bath (e.g., hot or cold water), heating or cooling to the desired temperature for the experiment, holding the temperature for a certain period of time, ③ pouring the reaction solution (e.g., ammonium persulfate solution) in one container into the other (e.g., potassium iodide + indicator solution) and mixing the solution, and continuing the reaction. In the teaching experiments, the number of students is numerous, and a plurality of groups of containers used for the experiments need to occupy a large space and use a plurality of constant-temperature water bath devices when controlling the temperature, so that huge pressure is brought to the space of a laboratory and the equipment of the constant-temperature water bath devices, and the problems of crowded space condition of the laboratory and high purchase cost of the devices can be solved through the integration and miniaturization of the reaction containers. Since the chemical reaction rate is closely related to the initial concentration of the reactants, complete and uniform mixing of the two sets of solutions in as short a time as possible is a prerequisite for accurate determination of the reaction rate. According to the mixing test tube with the upper parts of two adjacent tubes in the prior art (CN 221310716U), temperature control and mixing reaction of two groups of liquid in the same reactor can be realized, the occupied temperature control space is small, if the test tube is used for measuring the chemical reaction rate in the teaching experiment, as a certain space exists in the test tube above the communicating tube, when the liquid is mixed in the test tube in a fast inclined mode, part of the liquid flows into the space above the test tube due to the liquid blockage when the liquid flowing out of the bottom of the test tube flows through the communicating tube in a right-angle turning mode, the liquid retention phenomenon can cause the deviation of the material ratio of the mixed reaction liquid from the experimental design ratio and influence the accuracy of an experimental result, at the moment, the liquid retained above can be caused to flow into the mixed solution again by tilting (or inverting) the test tube again to obtain the mixed solution with the preset ratio, the waste time of the test tube is caused by the fact that the concentration of the transferred reactant in the initial reaction is lower than the preset concentration of the experiment, the experiment time is prolonged, and the accuracy of the experiment measurement is still greatly influenced. Aiming at the problems and the specific conditions of the experiments, the utility model provides the liquid mixing reactor, which not only meets the experimental requirements of independent temperature control of two groups of liquid reactants in the same reactor, but also ensures that no liquid is detained when the two groups of liquid are mixed rapidly, the mixing of the reactants is rapid and uniform, and the accuracy of experimental results is ensured. Disclosure of utility model The utility model aims to provide a liquid mixing reactor which can independently heat or cool two groups of liquid reactants to a required temperature before mixing, has no liquid retention during rapid mixing, achieves rapid and uniform mixing of different reactants, and ensures the accuracy of experimental results.
