[0002] Crucible is a container used for high-temperature processes such as melting, heating, and sintering. It is widely used in metallurgy, chemical industry, electronics, ceramics, glass and other industries. The main function of the crucible is to carry and protect the molten material to prevent it from contacting the outside world. At the same time, it can also withstand extreme environments such as high temperature and chemical corrosion.

[0003] The cooling of the crucible is of great significance for ensuring the safety and accuracy of experiments or production and extending the service life of the crucible. The existing crucible cooling methods are mostly to cool the crucible through cold air, cooling liquid and other media. Among the cooling methods, there is a method of cooling the crucible by surrounding it with a flexible pipe. This method may have the problem of high difficulty in installing the flexible pipe and high production cost. Because the crucible is in a high-temperature working environment, there is a problem that the pipe is exposed to high temperature for a long time, resulting in pipe failure, high maintenance cost, and affecting the accuracy of the experimental results.

[0004] Therefore, it is necessary to invent a modular crucible that can accelerate cooling to solve the above problems. Utility Model Content

[0021] The utility model provides Figure 1-4 A combined crucible with accelerated cooling is shown, comprising a crucible body 3 and a crucible cover 1 which is fitted at the top of the crucible body 3, wherein the outer wall of the crucible body 3 is detachably mounted with a crucible shell 2, the crucible body 3 is fitted with the outer wall of the crucible cover 1 and the inner wall of the crucible shell 2, the inner wall of the crucible shell 2 fitted with the crucible body 3 is provided with a plurality of spiral grooves 204 surrounding the crucible body 3, one end of the spiral groove 204 is provided with an air inlet 201 for conveying cooling gas, the portion of the spiral groove 204 located at the top of the crucible shell 2 is horizontally provided with a plurality of exhaust holes 208, and the ends of the plurality of exhaust holes 208 are provided with exhaust holes 1 203 in a vertical direction for discharging heat, the cooling gas flows in through the air inlet 201, and can drive the temperature of the outer surface of the crucible body 3 to drop when flowing in the spiral groove 204, and the hot air flows out from the exhaust hole 1 203 starting from the spiral groove 204, thereby achieving the purpose of accelerating the cooling of the crucible body 3.

[0022] A crucible upper edge 303 is provided at the top of the outer wall of the crucible body 3, and a positioning ring 206 is provided on the inner wall of the top of the crucible shell 2. The bottom end of the crucible upper edge 303 fits with the top of the positioning ring 206. The positioning of the positioning ring 206 and the crucible upper edge 303 helps the crucible body 3 to fit closely with the spiral groove 204, thereby forming a cooling cavity to achieve the purpose of cooling. Finally, the outer wall of the crucible body 3 and the inner wall of the crucible shell 2 are set at a matching inclination angle to increase the sealing effect of the cooling cavity.

[0023] A plurality of blocks 301 for positioning are arranged at the bottom of the upper edge 303 of the crucible, and a plurality of slots 207 for engaging with the blocks 301 are arranged at the top of the positioning ring 206 and at the position matching the blocks 301. The engagement of the slots 207 with the blocks 301 can prevent the crucible body 3 from shifting during heating, thereby reducing the sealing effect of the cooling pipe.

[0024] The lower half of the inner wall of the crucible shell 2 is provided with a plurality of support blocks 205 for supporting the crucible body 3.

The ventilation grooves 202 are provided to provide oxygen in the heating space for flame to burn fully, thereby ensuring the heating effect of the crucible body 3.

[0027] The utility model reduces the processing difficulty by providing a spiral groove 204 in the crucible shell 2, and forms a cooling channel when the inner wall of the crucible body 3 is fitted with the outer wall of the crucible body 3. Compared with the traditional method in which the pipeline is a certain distance away from the crucible body 3, this method allows the gas to contact the crucible body 3 with a larger contact area, thereby improving the cooling efficiency, accelerating the cooling speed of the crucible, and ensuring the safety and accuracy of experiments or production. By providing an exhaust hole 208 and an exhaust hole 1 203 in the spiral groove 204, hot air is discharged upward through the exhaust holes to avoid high-temperature gas from being sprayed around and causing potential safety hazards to personnel.
