The invention discloses a mixing device for chemical experiments suitable for mixing different reactants, which comprises a bottom plate, left and right vertical plates are arranged on the left and right sides of the bottom plate; a fixed rod is connected between the upper parts of the left and right vertical plates, and the fixed rod There are test tube clamps connected to the front and rear sides of the fixed rod; two test tube clamps arranged oppositely on the front and rear sides of the fixed rod form a set of test tube clamps, and the fixed rods at each set of test tube clamps are respectively equipped with low-frequency ultrasonic transducers and medium-frequency ultrasonic transducers. The transducer and the high-frequency ultrasonic transducer, the low-frequency vibrating device, the intermediate-frequency vibrating device and the high-frequency vibrating device are connected in parallel to each other and then connected to the power supply through wires. The present invention can control each ultrasonic transducer separately, and can also turn on all sub-switches, and carry out centralized control through three main switches, which has both the flexibility of individual control and the convenience of overall control, and produces the best The resonance effect promotes the smooth progress of chemical reactions and avoids energy waste.
Description
technical field [0001] The invention relates to the technical field of chemical experiments, in particular to an experimental mixing device. Background technique [0002] In chemical experiments, it is often necessary to mix different reactants (solid or liquid) into test tubes to facilitate the reaction. In order to speed up the mixing between different reactants (liquids) and make the reactants (liquids) participating in the reaction mix more evenly, technologies such as nitrogen stirring have appeared. In some chemical experiments, it is necessary to prepare different proportions of reaction solutions for batch comparison experiments, which requires simultaneous experiments on multiple sets of reaction vessels and mixing of the reactants in the reaction vessels. [0003] The applicant has developed a flip mixing experimental mechanism, and has applied for a patent and obtained authorization. This inverting mixing experiment mechanism can mix the reactants by inverting a...
