Description

Crucible supporting platform structure for precious stone growth Technical Field The utility model belongs to the technical field of precious stone processing, and particularly relates to a crucible supporting platform structure for precious stone growth. Background In the production of artificial sapphire, the temperature in a heater for sapphire growth is up to more than 2000 ℃, the quality of a sapphire finished product is directly influenced by the temperature environment, because the temperature in the heater is higher, a crucible for containing raw materials is supported by a high-temperature-resistant material, the crucible is supported to a certain height, the heater can uniformly heat the crucible outside the crucible, the bottom of a supporting table is connected with an external water-cooling device, the supporting table is prevented from melting due to overhigh temperature, the existing supporting table is generally of a complete platform structure, the bottom of the crucible is completely contacted with the surface of the supporting table, and the temperature difference between the upper part and the lower part of the crucible is caused by heat loss of the bottom of the crucible, so that the processing quality of the sapphire is seriously influenced. Disclosure of utility model The utility model aims to provide a crucible supporting platform structure for precious stone growth, wherein a plurality of spaced hollowed-out holes are formed in a supporting disc of a supporting platform assembly, and the hollowed-out holes are uniformly distributed on the supporting disc in an array mode, so that the contact area between the bottom of a crucible and the supporting disc can be reduced, the heat loss of the bottom of the crucible is reduced, the temperature difference between the upper part and the lower part of the crucible is reduced, and the processing quality of precious stones is improved. The utility model is realized by the following technical scheme: The crucible supporting platform structure for precious stone growth is characterized in that the supporting platform assembly is used for supporting a crucible and comprises a plugging rod and a supporting disc, one end of the plugging rod is in plug connection with the reflecting screen, the other end of the plugging rod is connected to the geometric center of the supporting disc, and a plurality of hollowed holes are formed in the supporting disc. Preferably, the support plate is provided with three hollowed-out holes, and the included angles among the three hollowed-out holes are the same. Preferably, the hollow hole is in a fan-shaped structure, and the side length of the outer side of the hollow hole is larger than that of the inner side of the hollow hole. Preferably, the distance from the edge of the support disc to the hollowed-out hole is 0.8cm-1cm. Preferably, a boss is arranged at the geometric center position below the supporting disc, and the boss is connected with the plug-in rod. Preferably, the radius of the boss is smaller than the distance from the inner side edge of the hollowed-out hole to the geometric center of the support disc. Preferably, the thickness of the boss is 0.8cm-1cm. Preferably, the thickness of the support disc is 1.2cm-1.5cm. Compared with the prior art, the utility model has the following advantages: 1) According to the utility model, the supporting plate of the supporting table assembly is provided with the plurality of spaced hollowed-out holes, the hollowed-out holes are uniformly distributed on the supporting plate in an array mode, so that the contact area between the bottom of the crucible and the supporting plate can be reduced, the heat loss of the bottom of the crucible is reduced, the temperature difference between the upper part and the lower part of the crucible is reduced, and the processing quality of precious stones is improved. 2) According to the utility model, the boss with the thickness of 1cm is arranged between the support disc and the plug rod, and the end part of the plug rod is connected with the boss, so that the stability of the support disc can be improved, the phenomenon of melting and breaking between the end part of the plug rod and the support disc can be avoided, and the safety of precious stone processing operation can be improved.
