[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 A ceramic centrifugal drying device includes a base plate 1, a rotating seat 2, a rotating plate 3, a ceramic mold body 4, and a housing 5. The rotating seat 2 is fixedly connected to the center of the top of the base plate 1. The rotating plate 3 is fixedly connected to the rotating end of the rotating seat 2. The ceramic mold body 4 is mounted on several support bars on the top of the rotating plate 3, with gaps between adjacent support bars. This allows heat to escape from below during air drying of the inner side of the ceramic mold body 4, thus drying the outer surface of the mold. The rotating seat 2 can be controlled by a motor, which is a mature existing technology and will not be described in detail here. The housing 5 is located at the edge of the top of the base plate 1, and a connecting column is welded to the top. The connecting column should be connected to the drive end of a lifting device. After the ceramic mold body 4 is fixed, the drive device controls the shell 5 to move down, forming a sealed space during drying to prevent heat from escaping. A stepper motor 6 and a fan 7 are fixedly installed on the top of the shell 5. The output shaft of the stepper motor 6 passes through the inside of the shell 5 and is fixedly connected to a screw 8. A drying component 9 is threaded along the axial direction on the screw 8. A guide rod 10 is also fixedly connected to the top of the inner wall of the shell 5. The drying component 9 is slidably connected to the surface of the guide rod 10 along the axial direction. A corrugated pipe 11 is installed on the air outlet of the fan 7. The bottom end of the corrugated pipe 11 is connected to the drying component 9. The corrugated pipe 11 can extend and retract when the drying component 9 moves vertically, and can also provide the effect of air delivery.

[0018] Specifically, the drying assembly 9 includes an air inlet duct 91 and a diversion ring 92. The air inlet duct 91 is located inside the diversion ring 92 and is fixedly connected by two horizontal plates 93. Two ventilation pipes 94 are also fixedly connected between the air inlet duct 91 and the diversion ring 92. Several air outlet pipes 95 are installed equidistantly around the outer surface of the diversion ring 92 and are interconnected with it. An electric heating mesh 96 is installed on the inner wall of the diversion ring 92 at a position corresponding to one end of the air outlet pipe 95.

[0019] Specifically, the top of the air inlet duct 91 is connected to the bottom of the corrugated pipe 11, and the two horizontal plates 93 are respectively provided with matching through holes 97 and screw holes 98 at the positions of the screw 8 and the guide rod 10.

[0020] Specifically, uprights 12 are symmetrically installed on the top of the rotating plate 3. A threaded part is opened on the surface of the uprights 12 near its top end. A locking ring 13 is threadedly connected to the corresponding threaded part on the surface of the uprights 12. After the cylindrical ceramic mold body 4 to be dried is placed on the support bar on the top of the rotating plate 3, the locking ring 13 is screwed onto the threaded part, which can achieve pressing and fixing from the top of the mold and improve its stability during rotation.

[0021] Specifically, several pressure relief holes 14 are equidistantly provided on the surface of the housing 5 near its top. The pressure relief holes 14 can dissipate the heat generated during the drying process in a timely manner, preventing the housing 5 from being unable to release pressure due to the sealed space, which would affect the normal use of the equipment.

[0022] This ceramic centrifugal drying device has a reasonable structural design and is easy to use. When drying cylindrical ceramic molds, it achieves centrifugal rotation. The drying equipment adopts a ring design and can move vertically back and forth, achieving efficient drying of the inner surface of the mold. During the process, heat can be evenly dissipated, effectively improving the drying efficiency and effect of ceramic molds, which is conducive to improving product quality.

[0023] In use, the cylindrical ceramic mold body 4 to be dried is placed on several support bars on top of the rotating plate 3. The locking ring 13 is screwed onto the threaded part of the upright 12 to press and fix the mold. Through the connection of the connecting column, the lifting device controls the shell 5 to move down and cover the ceramic mold body 4 from the outside to achieve a seal. During drying, the rotating seat 2 drives the rotating plate 3 and the ceramic mold body 4 above it to rotate slowly. The fan 7 is started, and with the connection of the bellows 11, air is continuously sent into the air inlet duct 91 and through the ventilation pipe. 94 is conveyed to the diversion ring 92, heated by the electric heating grid 96, and hot air is evenly sent out from multiple air outlets 95. During this process, the output shaft of the stepper motor 6 is controlled to drive the screw 8 to rotate intermittently in the forward and reverse directions. The drying component 9, which is threaded onto it, is limited by the guide rod 10 and performs reciprocating motion in the vertical direction, thereby drying the inner side of the ceramic mold body 4. The generated heat flow can flow out through the gap of the top support strip of the rotating plate 3 and rise to dry the outer surface of the mold, thus effectively improving the drying efficiency and effect.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
