[0002] Graphite powder, as an important industrial raw material, shows its wide application value in many fields. Especially in the high-temperature treatment process, the heating efficiency and uniformity of graphite powder are directly related to the quality of products and the production efficiency. However, traditional graphite powder heating equipment has exposed a series of problems in practical applications, such as uneven heating, low efficiency, and high energy consumption. These problems undoubtedly become the bottleneck restricting the application effect and production benefit of graphite powder; in the production and application process of graphite powder, the existence of fiber impurities is also an urgent problem to be solved. Due to their flexibility and winding properties, fiber impurities are prone to entangle with graphite powder, affecting the quality and application effect of graphite powder. Therefore, on the basis of the rotary drum heating technology, it is of great significance to further develop a rotary drum equipment capable of efficiently removing fibers. Content of the Utility Model

[0005] As a further improvement of the utility model, in order to ensure the stable and reliable operation of the rotary cylinder, a sealing disc is arranged at one end of the cylinder body, the cylinder body is welded to the sealing disc, a driven sprocket is also arranged on the outer side of the cylinder body, the driven sprocket is provided with a chain in cooperation, and the chain is connected to a driving motor.

[0006] As a further improvement of the utility model, in order to realize the continuous and uniform conveying of graphite powder and improve the production efficiency, connecting ribs are arranged on the sealing disc, the connecting ribs extend from one end of the cylinder body to the other end, and a screw conveying structure is arranged on the connecting ribs in cooperation. The screw conveying structure consists of several groups of barrel wall blades.

[0007] As a further improvement of the present utility model, in order to ensure the sealing performance of the device during the heating process and effectively prevent the leakage of graphite powder, a sealing structure is provided on the outer side of the sealing disk in cooperation with the cylinder body. The sealing structure includes a sealing bearing, and a first sealing plate and a second sealing plate are arranged between the sealing bearing and the sealing disk. The first sealing plate and the second sealing plate are stacked on each other.

[0008] As a further improvement of the present utility model, in order to facilitate the feeding and discharging of graphite powder and improve the operation convenience and maintenance efficiency of the device, the sealing bearing is connected with a rotating hollow shaft, and a feeding section hollow shaft head is arranged inside the rotating hollow shaft.

The heat is conducted from the rotating outer shell to the cylinder body to ensure that the sealing structure is intact and prevent the leakage of graphite powder during the heating process; the graphite powder is fed into the inside of the rotating hollow shaft through the feeding section hollow shaft head. As the rotating cylinder rotates, the graphite powder is gradually conveyed into the cylinder body. The graphite powder is evenly distributed in the cylinder body. Since the cylinder body is divided into multiple heating zones by multiple spacer plates, the graphite powder can receive sufficient heat in each zone. The heat generated by the electromagnetic heating coil is transferred to the graphite powder through the rotating outer shell and the cylinder body to realize the heating of the graphite powder. Due to the arrangement of the heat insulation layer, the heat dissipation is reduced and the heating efficiency is improved. During the heating process, the graphite powder continuously tumbles in the cylinder body as the rotating cylinder rotates to ensure uniform heating. At the same time, the screw conveying structure on the connecting rib and the blade on the cylinder wall assist the graphite powder to be conveyed forward in the cylinder body. After being heated in multiple heating zones, the graphite powder gradually reaches the required temperature and completes the heating process; after the heating is completed, the graphite powder gradually discharges from the other end of the cylinder body under the action of the rotation of the rotating cylinder and its own gravity.

[0011] The beneficial effects of the utility model are as follows: the utility model provides a rotating drum for graphite powder fiber removal, which is divided into multiple heating zones by multiple groups of partition plates.

A rotary outer shell 5 is arranged outside the cylinder body 2, and an electromagnetic heating coil 6 is arranged outside the rotary outer shell 5.

[0022] One end of the cylinder body 2 is provided with a sealing disc 7. The cylinder body 2 and the sealing disc 7 are welded. A driven sprocket 8 is further arranged on the outer side of the cylinder body 2. The driven sprocket 8 is provided with a chain 9 in cooperation. The chain 9 is connected to a driving motor 10.

[0023] The sealing disc 7 is provided with connecting ribs 11. The connecting ribs 11 extend from one end of the cylinder body 2 to the other end. A screw conveying structure 12 is arranged on the connecting ribs 11 in cooperation. The screw conveying structure 12 consists of several groups of barrel wall blades 13.

[0024] The cylinder body 2 and the sealing disc 7 are provided with a sealing structure 14 outside the sealing disc 7. The sealing structure 14 includes a sealing bearing 1401. A first sealing plate 1402 and a second sealing plate 1403 are arranged between the sealing bearing 1401 and the sealing disc 7.

[0025] The sealing bearing 1401 is connected to a rotary hollow shaft 15. A feeding section hollow shaft head 16 is arranged inside the rotary hollow shaft 15.

[0026] A heat preservation layer 17 is arranged between the cylinder body 2 and the electromagnetic heating coil 6.

[0027] When the utility model works, the power supply is connected and the driving motor 10 is started. The driving motor 10 drives the driven sprocket 8 to rotate through the transmission belt and the chain 9, and then the rotating cylinder 1 starts to rotate. Check whether the electromagnetic heating coil 6 is normally connected, set the required heating temperature, and the electromagnetic heating coil 6 starts to heat the rotating outer shell 5. The heat is conducted to the cylinder body 2 through the rotating outer shell 5, ensuring that the sealing structure 14 is intact to prevent the leakage of graphite powder during the heating process; the graphite powder is fed into the inside of the rotating hollow shaft 15 through the hollow shaft head 16 of the feeding section.
