[0002] Kaolin has a wide range of uses, including papermaking, ceramics and refractory materials, as well as coatings, rubber fillers, enamel glazes and raw materials for white cement. Kaolin production and processing require drying.

[0003] A kaolin drying device with announcement number CN220062346U is described, comprising a box body, both the upper and lower ends of which are open, and an upper cover and a lower cover respectively provided at the upper and lower ends. A heating tube is provided at the lower end of the upper cover to heat the inside of the box body. A sliding push plate is provided inside the box body, with the lower end of the push plate suspended above the lower cover to flatten the kaolin piled inside the box body, thereby increasing the drying efficiency.

[0004] Regarding the aforementioned technologies, the inventors believe that existing drying devices generate a large amount of water vapor during the drying of kaolin, and these devices often directly release this water vapor into the atmosphere without collecting or utilizing it.

The plurality of support legs 14 are evenly distributed on the bottom outer wall of the drying cylinder 1, which can provide stable support and thereby improve the stability of the entire device during use.

[0028] This utility model discloses a kaolin dry powder preparation device. A preheating cylinder 13 is provided on the top outer wall of the drying cylinder 1. A feed inlet is provided on the top outer wall of the preheating cylinder 13. A connecting hole is provided between the preheating cylinder 13 and the drying cylinder 1. An electromagnetic valve is installed in the connecting hole. A preheating pipe 18 is provided inside the drying cylinder 1. The preheating pipe 18 is arranged in an "S" shape. A connecting pipe 12 is provided between the second guide hood 6 and the preheating pipe 18. The connecting pipe 12 is wrapped with a heat insulation sleeve, which can utilize the residual heat of water vapor to preheat the kaolin to be dried, thereby improving the drying efficiency and saving energy.

[0029] This utility model discloses a kaolin dry powder preparation device. A motor 15 is installed on the top outer wall of a preheating cylinder 13. The output end of the motor 15 extends into the interior of the preheating cylinder 13 and is fixedly connected to a rotating rod 16. The other end of the rotating rod 16 extends into the interior of a drying cylinder 1 and is rotatably connected to the bottom inner wall of the drying cylinder 1.

After the kaolin inside the drying cylinder 1 is dried, the preheated kaolin inside the preheating cylinder 13 can be directly transported to the interior of the drying cylinder 1 for drying. This method can effectively improve drying efficiency and save energy, and has strong overall practicality.
