[0002] Crucible is an important part of laboratory instruments. It is a container for melting and refining metal liquid and solid-liquid heating reaction. It is the basis for ensuring the smooth progress of chemical reactions. There are many types and specifications of crucibles. When used, they are not restricted by production scale, batch size and type of smelting materials and can be selected arbitrarily. They have strong applicability and can ensure the purity of the smelted material. The raw materials for the production of crucibles can be summarized into three categories: one is crystalline natural graphite, the second is plastic refractory clay, and the third is calcined hard kaolin skeleton clinker.
[0003] One of the processes in the crucible production process is to dry the crucible. The drying needs to be carried out in a drying box or a drying furnace. After the existing crucible is dried in the drying box, the residual temperature is very high. In order to avoid harm to the staff, the crucible in the box needs to be cooled for a certain period of time to facilitate the staff to take the dried crucible out of the box. However, during the heat dissipation process, the crucible is always in the box, the air circulation is poor, and the heat dissipation effect is not good, resulting in a slow heat dissipation process.

[0025] In order to better understand the purpose, structure and function of the utility model, the crucible production and drying device of the utility model is further described in detail below in conjunction with the accompanying drawings.
[0026] like Figure 1-Figure 4As shown, a crucible production and drying device comprises a main box body 1, which is the drying box body. A reciprocating screw rod 3 is rotatably connected to the upper part of the outer part of the main box body 1. The outer part of the reciprocating screw rod 3 is spirally driven with a No. 1 sleeve block 20. An outer side of the No. 1 sleeve block 20 is equipped with a No. 1 L-shaped rod 2. A fixed rod 15 is fixedly connected to the lower part of the main box body 1. A No. 2 sleeve block 14 is sleeved on the outer side of the No. 2 sleeve block 14. A No. 2 L-shaped rod 22 is equipped on one side of the outer side. Support rods 13 are fixedly connected between the outer ends of the No. 1 L-shaped rod 2 and the No. 2 L-shaped rod 22. A plurality of placement racks 12 are installed between the outer sides of the two support rods 13 at equal intervals. A No. 2 bevel gear 19 is fixedly connected to one end of the outer part of the reciprocating screw rod 3. A main support frame 8 is fixedly connected to one side of the upper surface of the main box body 1. A No. 1 support plate 5 is installed on the lower surface of the No. 1 support plate 5. A driving motor 4 is installed on the output end of the driving motor 4. The driving shaft 21 is a movable shaft 21, and the bottom of the linkage shaft 21 passes through the top wall of the main box body 1 and is fixedly connected to the first bevel gear 18, and the first bevel gear 18 is meshed with the second bevel gear 19. By starting the output end of the drive motor 4 to rotate forward, the output end of the drive motor 4 can then synchronously drive the outer ring and the inner ring of the one-way bearing 16 to rotate synchronously, and then the rotation of the inner ring of the one-way bearing 16 can drive the linkage shaft 21 to rotate. Since the first bevel gear 18 is meshed with the second bevel gear 19, the first bevel gear 18 can drive the second bevel gear 19 to rotate when it rotates, and then the second bevel gear 19 can drive the reciprocating screw 3 to rotate, and then the reciprocating screw 3 can drive the first sleeve block 20 to move horizontally when it rotates, and then cooperate with the No. 1 L-shaped rod 2, the No. 2 L-shaped rod 22 and the support rod 13 to move synchronously, so that several placement racks 12 can be moved out of the main box body 1 to increase air circulation.
[0027] like Figure 1-Figure 3 As shown, the outer side of the main box body 1 is fixedly connected to the side away from the No. 1 support plate 5, and the transmission shaft 17 is rotatably connected to one side of the lower surface of the No. 2 support plate 7. A fan 9 is installed at the bottom of the transmission shaft 17, and the output end of the drive motor 4 is fixedly connected to the one-way bearing 16. The outer side of the linkage shaft 21 is fixed to the inner ring of the one-way bearing 16, and a transmission belt 6 is commonly sleeved between the outer ring of the one-way bearing 16 and the outer side of the transmission shaft 17. By reversing the output end of the drive motor 4, the inner ring and outer ring of the one-way bearing 16 rotate asynchronously, so as not to affect the position of the placement rack 12 after moving, and then the output end of the drive motor 4 can drive the outer ring of the one-way bearing 16 to rotate, and then the outer ring of the one-way bearing 16 can drive the transmission belt 6 to rotate, so that the transmission belt 6 can drive the transmission shaft 17 and the fan 9 to rotate, so as to achieve further heat dissipation of the crucible.
[0028] like Figure 1 and Figure 2As shown, fixed blocks 10 are installed on both sides of the upper surface of several placement racks 12, and several limit rods 11 are fixedly connected on both sides of the inner wall of the main box body 1, and the outer ends of the limit rods 11 pass through the interior of the fixed blocks 10 at the corresponding positions in sequence, so that when the placement rack 12 moves, the fixed blocks 10 can move synchronously outside the limit rods 11, which is convenient for providing real-time support for the placement rack 12 when it moves.
[0029] like Figure 1 and Figure 2 As shown, the upper and lower sides of the notch edge of the main box body 1 are integrally formed with convex plates, and the convex plates on the upper and lower sides are used to provide support for the reciprocating screw rod 3 and one end of the fixed rod 15.
[0030] like Figure 1-Figure 2 As shown, the overall length of the limit rod 11 is the same as the overall length of the reciprocating screw rod 3, ensuring that the placement rack 12 can always provide support for both sides of the placement rack 12 within the maximum adjustable range.
[0031] like Figure 1-Figure 4 As shown, the output end of the drive motor 4 is fixed to the outer ring of the one-way bearing 16, so that the inner and outer rings of the one-way bearing 16 can be driven to rotate synchronously by starting the forward and reverse rotation of the drive motor 4, thereby facilitating the selective rotation of the control linkage shaft 21.
[0032] The working principle of the crucible production and drying device is as follows: when the crucible to be placed on the placement rack 12 is dried, the door of the main box body 1 can be opened, and then the output end of the drive motor 4 is started to rotate forward, and then the output end of the drive motor 4 can synchronously drive the outer ring and the inner ring of the one-way bearing 16 to rotate synchronously, and then the rotation of the inner ring of the one-way bearing 16 can drive the linkage shaft 21 to rotate, because the No. 1 bevel gear 18 and the No. 2 bevel gear 19 are meshed, and then the No. 1 bevel gear 18 can drive the No. 2 bevel gear 19 to rotate when rotating, and then the No. 2 bevel gear 19 can drive the reciprocating screw 3 to rotate, and then the reciprocating screw 3 can drive the No. 1 sleeve block 20 to move horizontally when rotating, and then cooperate with the upper and lower L-shaped rods 2, the No. 2 L-shaped rods 22 and the support rods 13 to move synchronously, so that several placement racks 12 can be moved out of the main box body 1, increase air circulation, and accelerate the heat dissipation of the crucible;
[0033] After the placement rack 12 is moved out of the main box body 1, the output end of the driving motor 4 can be controlled to reverse. At this time, the inner ring and the outer ring of the one-way bearing 16 rotate asynchronously, thereby not affecting the position of the placement rack 12 after moving. Then the output end of the driving motor 4 can drive the outer ring of the one-way bearing 16 to rotate, and then the outer ring of the one-way bearing 16 can drive the transmission belt 6 to rotate, so that the transmission belt 6 can drive the transmission shaft 17 and the fan 9 to rotate, so that the fan 9 can be driven to rotate only by starting a single driving motor 4, thereby further accelerating the air circulation of the crucible moved out of the main box body 1, and further shortening the time required for heat dissipation.
[0034] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
