DETAILED DESCRIPTION

[0018] The crucible rapid cooling device of the present invention is described below in conjunction with the accompanying drawings.

[0019] In the first embodiment of the present application, Figure 1 and Figure 2As shown, the crucible rapid cooling device (hereinafter referred to as "this patent") includes an exhaust duct 1, a cooling cabinet 2, an exhaust fan 2-1, a cooling grille 2-2, a cooling grille body 2-21, a refrigerant circulation pipe 2-22, a duct fan 2-3, an air guide duct 2-4, a cooling bin cabinet door 3, a cooling bin 3-1, a crucible cooling platform 3-2, a metal mesh wall 3-21, a middle isolation mesh wall 3-22, a fence base 3-23, an annular rotating platform 3-24, an annular rotating seat 3-25, a pulling frame 3-26, an annular rotating platform driver 3-27, a slide rail 3-28, a side blower 4, an air inlet 5 and a control panel 6.

[0020] The utility model number is CN216778872U, which is a crucible stand for convenient crucible cooling (hereinafter referred to as "the patent"). The patent can only cool one crucible at a time, and the turnover efficiency is low when conducting a large number of parallel control experiments. At the same time, its cooling method is mainly achieved by blowing room temperature air directly from the bottom of the crucible. The cooling efficiency is not high and it is not very convenient to use. In addition, the patent directly discharges the heated air when cooling the crucible into the room, causing the indoor temperature to rise, which will further affect the cooling efficiency of the crucible and affect the comfort of the staff. The present invention uses a closed cooling cabinet 2 to effectively solve the problem of convection between the hot air around the crucible and the indoor air, ensuring that the crucible will not affect the indoor temperature when it is cooled. At the same time, the duct fan 2-3 is used to continuously blow cold air cooled by the cooling grille 2-2 into the cooling bin 3-1. The side blower 4 allows the cold air to continuously circulate inside the cooling bin 3-1, quickly taking away the temperature of the crucible and the materials therein. At the same time, the exhaust fan 2-1 can continuously discharge the air in the cooling bin 3-1 to ensure the cooling efficiency, effectively ensuring the turnover efficiency of the crucible during a large number of parallel control experiments.

[0021] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 3 and Figure 4As shown, a pull-out frame 3-26 of a crucible cooling table 3-2 is movably mounted on the inner side of the cooling bin 3-1 through a slide rail 3-28, an annular rotating seat 3-25 is fixedly mounted on the inner side of the pull-out frame 3-26 through a bracket, the annular rotating table 3-24 rotates in a groove on the upper part of the annular rotating seat 3-25, an annular rotating table driver 3-27 is fixedly mounted on the side of the annular rotating seat 3-25, the gear of the annular rotating table driver 3-27 engages with the annular toothed belt on the outer side of the annular rotating table 3-24, a fence base 3-23 is fixedly mounted on the inner side of the annular rotating table 3-24, a metal mesh wall 3-21 is fixedly mounted on the upper part of the annular rotating table 3-24 by screws, and a middle isolation mesh wall 3-22 is fixedly mounted in a cross shape on the inner side of the metal mesh wall 3-21.

[0022] In order to further optimize the working efficiency of the present application, in order to further improve the crucible cooling efficiency, such as Figure 5 As shown, the cooling grille body 2-21 of the cooling grille 2-2 is connected to the compressor and evaporator built into the cooling cabinet 2 through a refrigerant circulation pipe 2-22. In order to prevent the evaporator built into the cooling cabinet 2 from failing, the evaporator built into the cooling cabinet 2 is connected to the exhaust fan 2-1 through a pipeline, and the exhaust fan 2-1 can quickly take away the heat on the surface of the evaporator to prevent it from affecting the cooling of the crucible. In order to better support multiple crucibles, reinforcing ribs are welded on the surface of the metal mesh wall 3-21 and the middle isolation mesh wall 3-22.

[0023] When the utility model is in use, the specific operations are as follows:

[0024] When in use, open the cooling cabinet door 3, pull the drawer frame 3-26 to make it slide out along the slide rail 3-28, pick up the hot crucibles with the clamps in turn, and place them on the partition composed of the metal mesh wall 3-21 and the middle isolation mesh wall 3-22 on the annular rotating table 3-24. Four crucibles can be placed on each annular rotating table 3-24. Then reset the drawer frame 3-26, close the cooling cabinet door 3, control the equipment to start running through the control panel 6, and the compressor in the cooling cabinet 2 starts working, and the refrigerant is transported to the cooling grille body 2-21 through the refrigerant circulation pipe 2-22, so that the cooling grille 2-2 opens. The temperature starts to drop, the duct fan 2-3 draws in the outside air through the air inlet 5, and then enters the cooling chamber 3-1 after cooling through the cooling grille 2-2, the side blower 4 draws in a part of the cold air that passes through the cooling grille 2-2, and then blows it into the cooling chamber 3-1 from the middle, so that the air flow inside the cooling chamber 3-1 is stirred, the air flow speed is accelerated, and the temperature of the crucible and its contents is taken away more quickly, and the exhaust fan 2-1 works at the same time, so that the air inside the cooling chamber 3-1 is constantly and rapidly replaced, further accelerating the cooling speed of the crucible, and at the same time, the heated air will be discharged from the exhaust pipe 1 to the outside, preventing the hot air from accumulating indoors. In addition, the annular rotating table driver 3-27 drives the annular rotating table 3-24 to drive the crucible to rotate slowly on the annular rotating seat 3-25, so that the cold air can contact the crucible more comprehensively, further increasing the cooling speed.

[0025] In summary, the crucible rapid cooling device of the embodiment of the utility model places multiple crucibles on the crucible cooling table 3-2 of the cooling bin 3-1, and the metal mesh wall 3-21 and the middle isolation mesh wall 3-22 prevent the crucible from tipping over, and the annular rotating table driver 3-27 of the crucible cooling table 3-2 drives the annular rotating table 3-24 to continuously rotate on the annular rotating seat 3-25, and the duct fan 2-3 continuously blows cold air cooled by the cooling grille 2-2 into the cooling bin 3-1, and the side blower 4 allows the cold air to continuously circulate inside the cooling bin 3-1 to quickly take away the temperature of the crucible and the material therein, and at the same time, the exhaust fan 2-1 can continuously discharge the air in the cooling bin 3-1 to ensure the cooling efficiency, and at the same time, the closed cooling cabinet 2 and the exhaust duct 1 connected to the outside can directly discharge the hot air to the outside, so that multiple crucibles can be cooled quickly and efficiently, and the crucible turnover efficiency in laboratories and factories can be effectively improved without affecting the comfort of the staff.
