Technical Field
[0001] The utility model relates to the technical field of magnetic stirring equipment, in particular to a glass heating pot component of a heat-collecting magnetic stirrer. Background Art
[0002] A magnetic stirrer is a common laboratory equipment that uses a magnetic field to place a magnetic stirrer in a liquid to achieve the purpose of stirring and mixing. Magnetic stirrers are widely used to stir solutions, reactants and reagents. They can be used to dissolve solids, mix liquid reagents, catalyze reactions, etc. Some liquid stirring requires a heating system. At present, the magnetic stirrer industry, especially the thermal collector magnetic stirrer, uses a metal stainless steel heating pot. It is difficult to visually see the chemical reaction of the liquid inside the bath, and improvements are needed. Therefore, we propose a glass heating pot assembly for a thermal collector magnetic stirrer. Utility Model Content

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0016] Embodiment 1, as Figure 1-2 As shown, the utility model provides a technical solution: a glass heating pot assembly of a heat-collecting magnetic stirrer, comprising a heating base 4, a glass pot 2 and a protective cover 3, the heating base 4 is arranged on the top surface of the magnetic stirrer, the bottom of the glass pot 2 is connected to the top surface of the heating base 4 by bonding, the protective cover 3 is fixedly arranged on the top of the magnetic stirrer, the protective cover 3 is located on the outside of the glass pot 2, and a visual window 5 is fixedly arranged on the surface of the protective cover 3.
[0017] In a specific embodiment of the present invention, the components of the magnetic stirrer for achieving magnetic stirring are: a micro motor and a magnet. The motor drives the magnet to rotate to generate a changing magnetic field. In conjunction with a magnetic stirring rod placed inside the glass pot 2, the magnetic stirring rod can be driven to rotate and stir inside the glass pot 2. The heating base 4 is composed of a heating element and a heat-conducting seat. The power of the heating base 4 is provided by a power cord and a power plug of the magnetic stirrer. The start and stop control of the heating base 4 is independently controlled by a magnetic stirrer controller (not shown in the figure). In order to ensure the stability of the assembly of the glass pot 2 and the heating base 4, a high-temperature resistant sealant (fluororubber sealant) is filled at the connection between the glass pot 2 and the heating base 4. The protective cover 3 adopts an aluminum alloy metal outer cover to resist debris generated by the explosion of the glass pot 2. The visual window 5 adopts borosilicate glass to achieve a certain heat resistance and maintain light transparency. The internal chemical reaction can be seen through the visual window 5 and the glass pot 2.
[0018] In the preferred technical solution, the top end surface of the glass pot 2 is flush with the top end surface of the protective cover 3, and the gap between the top end surface of the glass pot 2 and the top end surface of the protective cover 3 is filled with a sealing ring 1. The sealing ring 1 is a fluororubber sealing ring, which is used to prevent the liquid in the glass pot 2 from spilling into the gap between the top end surface of the glass pot 2 and the top end surface of the protective cover 3, thereby protecting the heating base 4.
[0019] In the preferred technical solution, the heating base 4 and the bottom of the glass pot 2 are filled with high-temperature resistant sealant. In order to ensure the stability of the assembly of the glass pot 2 and the heating base 4, high-temperature resistant sealant (fluororubber sealant) is filled at the connection between the glass pot 2 and the heating base 4. Fluororubber has excellent chemical corrosion resistance and high-temperature stability, and can maintain stability at higher temperatures.
[0020] In the preferred technical solution, the glass of the glass pot 2 is high borosilicate glass, which has a higher softening temperature and a lower thermal expansion coefficient, and can maintain stability in a high temperature environment; it has a lower chemical solubility and can resist corrosion by chemicals such as acids and alkalis.
[0021] In the preferred technical solution, the distance between the outer wall of the glass pot 2 and the inner wall of the protective cover 3 is set to 10 mm, and a certain distance is set to prevent heat from being directly conducted to the protective cover 3 and causing overheating of the protective cover.
[0022] Working principle: by placing the liquid to be stirred into the glass pot 2, placing the magnetic stirring rod into the glass pot 2, turning on the heating base 4, the motor of the magnetic stirrer drives the magnet to rotate to generate a changing magnetic field, thereby driving the magnetic stirring rod inside the glass pot 2 to rotate, the liquid inside the glass pot 2 can be heated and stirred, and the internal changes can be observed through the visual window 5.
