[0002] Heat conducting powder is an important filler for improving the heat conducting performance of materials, and is mainly made of inorganic materials such as alumina. These materials are widely used due to their stable chemical properties, good insulating performance and high cost performance. Heat conducting powder has various forms, including spherical, quasi-spherical and flaky forms. Different forms of heat conducting powder differ in heat conducting performance, processing viscosity and mixing uniformity. For example, spherical and quasi-spherical alumina are widely used in the market because of their good fluidity, uniform mixing with the polymer matrix and better uniformity of the prepared composite material. The main function of heat conducting powder is to improve the heat dissipation effect, maintain the normal operation of equipment, prevent overheating damage and prolong the service life of equipment. As a heat conducting medium, heat conducting powder has good heat conducting performance, can effectively transfer heat, shorten the heat dissipation time and reduce the temperature.
[0003] In the drying process of the existing heat conducting powder, the powder is in a wet state and has adhesion, and the interaction between particles is strong, so the heat conducting powder is prone to caking. At present, the heat conducting powder is usually directly put into the drying cylinder for drying treatment by the air heater. However, the caked heat conducting powder is prone to accumulate at the bottom of the drying cylinder due to its weight, resulting in poor drying effect of the heat conducting powder. SUMMARY

[0010] In the above technical scheme, further, the fixed pipe is connected with an input pipe at the middle of one side.
[0011] In the above technical scheme, further, the connecting pipe is uniformly connected with stirring rods on both sides, the connecting pipe is connected with a scraper at the lower part of one side, the scraper is in contact with the lower end of the inner wall of the cylinder at one side, and the connecting pipe is connected with support pipes on both sides at the upper part.

The lifting plates lift the material from the lower part of the screen cylinder's inner wall, while the rotating rod drives multiple dispersing rods to break up any clumps of the thermally conductive powder. Simultaneously, hot air from the fixed pipe passes through the air supply pipe, rotary joint, and connecting pipe into the two support pipes. The hot air from the two support pipes evenly passes through multiple drying heads to dry the material inside the screen cylinder. The rotating rod also drives the connecting pipe to rotate, allowing the multiple drying heads to rotate with the support and connecting pipes, ensuring that the hot air discharged from one side of the drying heads is evenly sprayed around the screen cylinder, improving the drying effect on the material inside. Furthermore, as the support pipes rotate, two cleaning brushes follow, brushing the area below the screen cylinder to prevent powdery material from clogging the screen holes. Once the material inside the screen cylinder is broken up, it falls through the screen holes into the cylinder body, preventing clumps from accumulating at the bottom. This rapid drying of the thermally conductive powder improves its drying efficiency. Attached Figure Description

In use, the material is fed into the screen cylinder 3 through the feed pipe, retaining the agglomerated thermally conductive powder raw material inside the screen cylinder 3.

Multiple drying heads 18 dry the material inside the screen cylinder 3. Simultaneously, the rotating rod 5 drives the connecting pipe 9 to rotate, and the multiple drying heads 18 can rotate with the support pipe 17 and the connecting pipe 9, so that the hot air discharged from one side of the multiple drying heads 18 is evenly sprayed around the screen cylinder 3, improving the drying effect on the material inside the screen cylinder 3.

At the same time, the drive motor 4 works to drive the rotating rod 5 to rotate, which in turn drives the lifting plate 6 to lift the material at the lower end of the inner wall of the screen cylinder 3. At the same time, multiple dispersing rods 7 follow the rotating rod 5 to rotate, and the multiple dispersing rods 7 can disperse the material lifted into the screen cylinder 3 when they rotate.

When the connecting pipe 9 rotates, it can also drive the two support pipes 17 and multiple drying heads 18 to rotate, so that the hot air can enter the screen cylinder 3 from all sides, achieving preliminary drying treatment of the material inside the screen cylinder 3. When the two support pipes 17 rotate, they drive the two cleaning brushes 13 to brush the bottom of the screen cylinder 3, preventing the screen holes at the bottom of the screen cylinder 3 from becoming blocked.
