[0003] Traditional ceramic cooling devices often cool down by natural cooling, but natural cooling is slow. The existing technology speeds up the cooling speed by ventilation. When using ventilation to cool down the fired hollow cylindrical ceramic products, the heat dissipation rates inside and outside the ceramic products are often different due to the influence of the environment and the structure of the ceramic products. Therefore, during the cooling process, the temperature inside and outside the ceramic products is easily unbalanced, resulting in deformation, distortion, and cracking of the ceramics. In view of the above problems, there is a need for a cooling device for fired ceramic products that can balance the temperature inside and outside the ceramic products, thereby avoiding deformation, distortion, and cracking of the ceramic products.

[0021] By arranging air outlet ducts inside and outside the ceramic product 5, the temperature inside and outside the ceramic product 5 can be reduced simultaneously, so as to increase the balance of the temperature inside and outside the ceramic product 5. In addition, by arranging internal and external sensors, the temperature inside and outside the ceramic product 5 can be monitored in real time, so as to ensure that the temperature inside and outside the ceramic product 5 drops synchronously, and avoid deformation, distortion, cracking and other problems of the ceramic product 5.

[0028] Principle of the utility model

[0029] like Figure 3-4The figure shows a state in which no ceramic product 5 is placed. The lifting motor 20 is started. Driven by the moving block 22, the lifting block 6 drives the collar 4 to move upward to make room for the placement of the ceramic product 5. The ceramic product 5 is placed on the placement net 18 in the positioning groove 19, and the lifting motor 20 is controlled to work, so that the collar 4 is placed on the ceramic product 5, and the heat dissipation pipe 7 is inserted into the ceramic product 5. Figure 1-2 As shown. The first cooling fan 9 and the second cooling fan 11 can blow air to cool the inside and outside of the ceramic product 5 through the inner air outlet duct 28 and the outer air outlet duct 26 respectively, thereby increasing the heat dissipation uniformity of the entire ceramic product 5. The external temperature sensor 25 can monitor the temperature of the outer surface of the ceramic product 5, and the internal temperature sensor 27 can monitor the temperature inside the ceramic product 5, and transmit the monitoring result to the central processing controller 13. The central processing controller 13 analyzes the internal and external temperatures of the ceramic product 5. When the internal temperature is higher than the external temperature, the power of the first cooling fan 9 is increased through the first power regulator 10, and the power of the second cooling fan 11 is reduced through the second power regulator 12; when the internal temperature is lower than the external temperature, the power of the first cooling fan 9 is reduced through the first power regulator 10, and the power of the second cooling fan 11 is increased through the second power regulator 12, so as to achieve a balance between the internal and external cooling rates and avoid deformation, distortion, cracking and other problems. At the same time, the heat dissipation fan 15 can cool the bottom of the ceramic product 5 through the placement net 18 to avoid the problem of slow heat dissipation at the bottom of the ceramic product 5 due to the placement effect.
