Description

Technical Field

[0001] The utility model relates to the technical field of chemical reaction instruments, in particular to a chemical reaction device with magnetic material stirring and side-entry mechanical stirring in a photochemical reaction instrument. Background Art

[0002] In the study of photocatalytic reactions, photochemical reaction instruments are required. Photochemical reaction instruments are the most important instruments for photocatalytic reactions in current laboratory research. They are mainly composed of light source controller, reaction dark box, and low-temperature constant temperature bath. The reaction dark box is the main place for the reaction, including light source, reactor, stirring and other devices.

[0003] When conducting a photocatalytic reaction experiment, the pollutants need to be placed in the reactor. In order to make the catalyst fully contact with the pollutants and prevent aggregation, a stirring device is required. The most commonly used stirring device is a magnetic stirrer. Simply clean the rotor and flip it into the reactor, and then place the reactor on the magnetic stirrer to complete the stirring. The magnetic stirrer mainly uses the principle of like charges repel and opposite charges attract in the magnetic field. The magnetic field is used to push the magnetic rotor placed in the container to achieve the purpose of stirring the liquid. Therefore, a magnetic stirrer cannot be used to stir photocatalytic materials containing magnetism.

[0004] Mechanical stirring is mainly composed of a motor and a stirring rod. The stirring rod can be made of stainless steel or polytetrafluoroethylene. However, the main machine of the mechanical stirring is bulky and must be inserted vertically into the reactor from above for stirring. In a dedicated photocatalytic reactor, the light source must be inserted vertically from above the reactor, so traditional mechanical stirrers are difficult to use.

[0005] Therefore, there is an urgent need on the market for a side-entry stirring chemical reaction device that can be used for stirring magnetic materials in a photochemical reaction instrument. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a side-entry stirring device for magnetic materials, which can be used in a chemical reaction device for stirring magnetic materials in a photochemical reactor.

[0007] The technical solution of the utility model is:

When the low-temperature constant temperature bath is turned on, water circulation can be achieved, and the temperature during the reaction process can be adjusted by setting the circulating water temperature.

[0011] Preferably, the reaction dark box also includes a heat dissipation group, a xenon lamp and a lifting platform. The xenon lamp shines vertically above the reaction solution through circulating cooling water, which can not only ensure sufficient contact between the reaction solution and the light source, but also avoid the temperature increase under the irradiation of the xenon lamp affecting the accuracy of the experiment.

[0012] Preferably, the reaction dark box is a rectangular parallelepiped consisting of a top, a bottom, a left side and a right side. The heat dissipation group is arranged on the top of the dark box. The heat dissipation group is a metal heat dissipation fan. The xenon lamp is vertically installed above the reactor. The power of the xenon lamp is 250W-350W. The lifting platform adjusts the height of the xenon lamp.

[0013] Preferably, the stirring rod is made of ABS material, and comprises a connector and a stirring paddle, the connector is in a horizontal straight line, and the stirring paddle is arranged at the top of the connector.

[0021] 1. The chemical reaction device for side-entry stirring of magnetic materials in this application combines an ABS stirring rod with a handheld electric grinder to change the symmetrical structure of the traditional stirring paddle, so that the stirring paddle is in a "B" shape. This shape can make the stirring more sufficient and uniform, and due to the hollow design, no splashing will occur during the stirring process. During the reaction process, the stirring speed can be adjusted by adjusting the grinding machine speed;

[0022] 2. The power of the stirring rod in this application is mainly provided by a handheld electric grinder. Compared with the main unit of a traditional stirrer, it is lighter and more compact. After being fixed on the iron frame, the angle can be flexibly adjusted to achieve the side entry of the stirring rod. And by adjusting the position of the stirring rod on the iron frame, the depth of the stirring paddle penetrating into the solution can be changed. And the stirring device is not limited to the application of photochemical reactors, but can also be used in other magnetic material stirring devices with side openings in other reaction vessels;

[0023] 3.
