Magnetic stirrers are suitable for simultaneous stirring or stirring and heating, and are suitable for liquids or solid-liquid mixtures with low viscosity. Currently, most magnetic stirrers on the market are stirring devices. A flask is placed on the stirring device, the liquid is placed in the flask, and the magnetic stirring bar is placed in the liquid. Using the principle of magnetic field and eddy current, that is, using the characteristic of anisotropic repulsion of magnetic materials, the polarity of both ends of the base is constantly changed. So, let's learn about the manufacturing method of magnetic stirrers!

  Traditional magnetic stirrers place a container similar to a flask on the base to stir the liquid in the container. Some magnetic stirrers have a bowl-shaped stirring sleeve on the base. The former can only stir liquids in metal containers such as reaction kettles and cannot control the temperature. The latter can stir reaction kettles and control the temperature, but because the stirring cover is a basin-shaped structure and the reaction kettle is located inside the stirring cover, the temperature field measured by the temperature probe is uneven. Sometimes the bottom temperature is high and the top temperature is low. The control of the liquid temperature inside the reaction kettle, that is, the temperature field of the reaction kettle is uneven, which affects the control of the liquid temperature in the stirring cover; the reaction kettle is placed in the oven, the temperature can be controlled, but it cannot be stirred.

  In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a magnetic stirrer with a more uniform internal temperature field. In order to achieve the above purpose, this utility model provides a magnetic stirrer with a magnetic stirring device, a stirring cover, and a temperature measuring mechanism for measuring the reaction liquid inside the stirring cover, which is characterized in that a stirring cover accommodating chamber is set, and the stirring cover accommodating chamber is a columnar structure. By adopting the above technical scheme, the shape of the stirring cover can be changed, and the columnar structure has a more uniform temperature field than the traditional bowl shape. The reaction kettle is placed in the container of the stirring cover, so that the liquid temperature in the reaction kettle is uniform, and the purpose of stirring and effectively controlling the temperature is achieved. This utility model also sets the above columnar structure as a cylindrical structure.

  With the above technical scheme, most reaction kettles on the market have a bowl-shaped structure. The cylindrical structure of the stirring cup container is set, so that after the reaction kettle is placed in the stirring cup container, the surrounding temperature field is more uniform. This utility model also sets the connection method between the stirring cover sealing cover and the stirring cover. By adopting the above structure, the temperature field inside the stirring cover accommodating chamber can be made more uniform. This utility model sets a magnet between the magnetic stirring device and the stirring cover. With the above technology, the magnetic force is stronger, and the stirring effect is obvious. This utility model also sets: the temperature measuring mechanism includes a temperature probe, a temperature display, and a temperature controller. The stirring cover is provided with a through hole matching the temperature probe, and the temperature probe is placed in the through hole and exposed to the stirring cover accommodating chamber.

  With the above technical scheme, the stirring cover can be completely sealed, and there is no need to expose a small opening on the opening of the stirring cover to measure the temperature probe, which can make the temperature measurement more accurate. This utility model sets a reaction kettle in the stirring cover accommodating chamber, and a receiving tray for receiving the reaction liquid is set in the reaction kettle. The receiving tray is made of polytetrafluoroethylene material, and a magnetic stirring bar is set in the receiving tray. By adopting the above technology, polytetrafluoroethylene has the characteristics of strong resistance to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. Therefore, it is better to put the liquid into a polytetrafluoroethylene container than to put it directly into a metal reaction kettle.

  The magnetic stirrer can also stir and control the temperature of the liquid inside metal containers such as reaction kettles. The magnetic stirrer has a magnetic stirring device, a stirring cup, and a temperature measuring mechanism for measuring the temperature of the reaction liquid inside the stirring cup. The magnetic stirrer has a stirring cup accommodating chamber and a stirring cup sealing cover. The temperature measuring mechanism of the stirring cup sealing cover includes a temperature probe, a temperature display, and a temperature controller. The stirring cover is provided with a through hole matching the temperature probe, and the temperature probe is placed in the through hole and exposed to the stirring cover accommodating chamber. A receiving tray for receiving the reaction liquid is provided in the stirring cover accommodating chamber, and the receiving tray is made of polytetrafluoroethylene material. A magnetic stirrer is provided in the receiving tray.
