[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1 - 5 shown, the present invention provides a corrosion-resistant crucible, including a platinum crucible 11, a pot lid 12 is arranged on the top of the platinum crucible 11, an anti-condensation mechanism 2 is arranged on the bottom of the pot lid 12, the anti-condensation mechanism 2 includes a motor 201, the output end of the motor 201 is fixedly connected with a rotating shaft 202, a plurality of scrapers 203 are fixedly connected to the bottom of the rotating shaft 202, the outer surface of the scraper 203 is slidably attached to the inner wall of the platinum crucible 11, a plurality of stirring plates 204 are fixedly connected to the outer surface of the rotating shaft 202 at equal intervals, a plurality of through holes 205 are arranged in an array on the outer surface of the stirring plate 204, the motor 201 is fixedly installed at the center of the top of the pot lid 12, the output end of the motor 201 slidably penetrates through the top of the pot lid 12 and extends downward, a foot 1 is arranged at the bottom of the platinum crucible 11, a pressure relief valve 3 is arranged near the edge of the top of the pot lid 12, a lower edge 13 is arranged near the edge of the bottom of the pot lid 12, and the outer surface of the lower edge 13 is closely attached to the position near the top of the inner wall of the platinum crucible 11.

[0024] The effect achieved by the entire Example 1 is that the platinum crucible 11, the rotating shaft 202, the stirring plate 204, and the scraping plate 203 are all made of platinum material, which has excellent corrosion resistance and can resist the erosion of various chemical substances. When using the platinum crucible 11 to heat, melt, react, etc. on solid or liquid substances, by adding the solid or liquid substances into the interior of the platinum crucible 11 and then heating, during the process, the pot lid 12 is placed on the top of the platinum crucible 11 and under the frictional force between the lower edge 13 and the inner wall of the platinum crucible 11, the pot lid 12 maintains good stability. Subsequently, the motor 201 is started to drive the rotating shaft 202 to rotate slowly. When the rotating shaft 202 rotates, the stirring plate 204 on the surface of the rotating shaft 202 will stir the substances inside, so as to make the heat evenly distributed and improve the experimental efficiency. At the same time, during the rotation of the scraping plate 203 on the surface of the rotating shaft 202, the scraping plate 203 will slide along the inner wall of the platinum crucible 11, so that the experimental substances are difficult to adhere to the inner wall of the platinum crucible 11, thus solving the problem that the experimental substances adhere to the inner wall of the platinum crucible 11 and cause corrosion to it, and improving the service life of the platinum crucible 11. By opening through holes 205 on the surface of the stirring plate 204, the melted experimental substances can pass through the stirring plate 204 through the through holes 205 when being stirred, which increases the complexity of the flow of the experimental substances. The setting of the pressure relief valve 3 avoids the problem that the pot lid 12 is lifted due to the increase in air pressure inside the platinum crucible 11 after heating, and the feet 1 facilitate the placement of the platinum crucible 11.

[0025] Example 2, as Figures 1 - 4 shown, a support handle 31 is fixedly connected to the left position on the outer surface of the pot lid 12, a connecting rod 32 is fixedly connected to the top of the pot lid 12 near the right edge, the top end of the connecting rod 32 is fixedly connected to a grip 33, a heat-insulating sleeve 34 is sleeved on the outer surface of the grip 33, and the grip 33 and the support handle 31 are arranged in parallel as a whole.

[0026] The effect achieved by the entire Example 2 is that by setting the grip 33 and the connecting rod 32, it is convenient to take and disassemble the pot lid 12, and the heat-insulating sleeve 34 is sleeved outside the grip 33 to avoid scalding. After the pot lid 12 is removed after the platinum crucible 11 is used, by making the grip 33, the support handle 31 and the tabletop fit, at this time, the rotating shaft 202, the scraping plate 203 and the stirring plate 204 after stirring the experimental substances will be lifted and suspended, and will not damage the experimental tabletop, which is more convenient to use. The grip 33 is made of tungsten metal, which is heavy and has a low thermal conductivity, and together with the connecting rod 32, it plays a role in counterweight, while the support handle 31 is mainly used to form a support point.

[0027] Working principle: When using the platinum crucible 11 to heat, melt, react, etc. on solid or liquid substances, the solid or liquid substances are added to the inside of the platinum crucible 11 and then heated. During the process, the pot lid 12 is placed on top of the platinum crucible 11, and under the frictional force between the lower edge 13 and the inner wall of the platinum crucible 11, the pot lid 12 maintains good stability. Subsequently, the motor 201 is started to drive the rotating shaft 202 to rotate slowly. When the rotating shaft 202 rotates, the stirring plate 204 on the surface of the rotating shaft 202 will stir the substances inside, so as to make the heating uniform and improve the experimental efficiency. At the same time, during the rotation of the scraping plate 203 on the surface of the rotating shaft 202, the scraping plate 203 will slide along the inner wall of the platinum crucible 11, so that it is difficult for the experimental substances to adhere to the inner wall of the platinum crucible 11, thus solving the problem that the experimental substances adhere to the inner wall of the platinum crucible 11 and cause corrosion to it, and improving the service life of the platinum crucible 11. And by setting the handle 33 and the connecting rod 32, it is convenient to take, disassemble and assemble the pot lid 12, and a heat insulation sleeve 34 is sleeved outside the handle 33 to avoid scalding. After the pot lid 12 is removed after the platinum crucible 11 is used up, the handle 33, the support handle 31 and the desktop can be made to fit. At this time, the rotating shaft 202, the scraping plate 203 and the stirring plate 204 after stirring the experimental substances will be tilted and suspended, and will not damage the experimental desktop.

[0028] The wiring diagram of the motor 201 in the present utility model belongs to the common knowledge in the art, and its working principle is already known technology. Its model is selected according to the actual use, so the control method and wiring layout of the motor 201 will not be explained in detail.

[0029] The above are only the preferred embodiments of the present utility model, and are not limitations to the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
