Description

TECHNICAL FIELD

[0002] The heat collecting type heating magnetic stirrer mainly comprises a magnetic stirrer and a heat collecting type heating system. The magnetic stirrer rotates a magnetic rotor built in a reactor through magnetic force to realize uniform mixing of reactants, and the heat collecting type heating system provides heat required by the reaction through radiation heating to ensure that the reaction is carried out at a constant temperature.

[0003] The heat collecting type heating magnetic stirrer on the market usually fixes a flask in a heat collecting type heating magnetic stirrer cavity through vertical movement and clamping pieces to perform water bath or oil bath heating. However, the fixing device provided by the clamping pieces depends on fastening screws for fastening, and the fastening screws are prone to thread slippage, which leads to unstable fixing, and the fastening degree of the clamp and the position of the flask need to be adjusted multiple times during installation and use, which is extremely inconvenient to use. When the reaction container is heated in the heating medium, the reaction container is completely immersed in the high-temperature heating medium due to its small size, and the reaction container cannot be taken out by the fixing device instead of the experimenter's hand, which has great safety hazards. The reaction container fixed by the traditional clamp is limited to a flask, so the types of reaction containers used in the heat collecting type heating magnetic stirrer have great limitations.
