[0018] Step 2: The drum heating component is started, the electromagnetic coil is energized, and the rotating drum begins to heat. The rotating drum is evenly heated under the action of the electromagnetic coil and maintains stable operation through the upper and lower drag groups;

[0019] Step 3: The rotating cylinder is divided into multiple heating zones by a partition plate. After the graphite powder enters the rotating cylinder, it enters the heating zones in sequence through a screw conveying structure. The temperature detector in each heating zone monitors the temperature in real time to ensure that the heating is uniform and does not exceed the set value. The assembly ring, the connecting strip and the screw conveying structure cooperate with each other to push the graphite powder forward and complete the heating process at the same time.

[0023] Step 7: The cooling oil enters the drive shaft through the cooling oil inlet of the rotary joint and flows into the oil cooling blades to exchange heat with the graphite powder, thereby reducing the temperature of the graphite powder. During the entire heat treatment process, the screw conveyor rotates continuously to transport the graphite powder from the feed port to the discharge port;

[0024] Step 8: A magnetic frame is set at the discharge port. Multiple groups of magnetic bars inside the magnetic frame can attract and separate iron impurities in the graphite powder.

The rotating cylinder is divided into a plurality of heating intervals by a partition plate, and the graphite powder enters these heating intervals in sequence. The temperature detector in each heating interval monitors the temperature in real time to ensure that the heating is uniform and does not exceed the set value. The assembly ring, the connecting strip and the threaded conveying structure cooperate with each other to push the graphite powder forward and complete the heating process at the same time. The fiber impurities mixed in the graphite powder are removed by heating and burning; the heated graphite powder enters the cooling section through the heating outlet, the infrared temperature detection probe monitors the temperature of the graphite powder to ensure that the temperature of the graphite powder entering the cooling section meets the cooling requirements, and the heat transfer oil in the cooling row begins to absorb the heat of the graphite powder to perform preliminary cooling , the fan delivers gas to the inside of the rotating cylinder through the oxygen pipe to provide air for auxiliary impurity combustion, and turns on the second drive motor to drive the drive shaft of the screw conveyor to start rotating, preparing for further cooling and transportation of the graphite powder; the graphite powder after preliminary cooling enters the inside of the screw conveyor in the cooling and transportation component from the feed port. With the double rotation of the threaded cooling structure in the screw conveying shell, the graphite powder is gradually pushed toward the discharge port, and the cooling oil enters the inside of the drive shaft through the cooling oil inlet of the rotary joint, and flows into the oil cooling blades to exchange heat with the graphite powder to further reduce the temperature of the graphite powder.

7. The working process of the integrated equipment for removing fiber and transporting graphite powder according to claim 1 is characterized in that: The workflow includes the following steps: Step 1: Pour graphite powder into the storage hopper (2), pay attention to controlling the loading amount to avoid overloading, turn on the first drive motor (7), drive the rotary bearing (901) and the drive plate (903) of the screw conveyor (3) to rotate through the transmission belt (904), and the screw conveyor (3) starts to work, and conveys the graphite powder in the storage hopper (2) downward to the roller heating component (4); Step 2: The drum heating assembly (4) is started, the electromagnetic coil (403) is energized, and the rotating drum (401) begins to be heated. The rotating drum (401) is evenly heated under the action of the electromagnetic coil (403) and is kept in stable operation by the upper and lower drag groups (402); Step 3: The rotating cylinder (401) is divided into a plurality of heating zones (404) by a partition plate (405). After the graphite powder enters the rotating cylinder (401), the graphite powder enters the heating zones (404) in sequence through a screw conveying structure (409). The temperature detector (406) in each heating zone (404) monitors the temperature in real time to ensure that the heating is uniform and does not exceed the set value. The assembly ring (407), the connecting strip (408) and the screw conveying structure (409) cooperate with each other to push the graphite powder forward and complete the heating process at the same time. The fiber impurities mixed in the graphite powder are removed by heating and combustion. Step 4: The heated graphite powder enters the cooling section (5) through the heating outlet (411); the infrared temperature detection probe (502) monitors the temperature of the graphite powder to ensure that the temperature of the graphite powder entering the cooling section (5) meets the cooling requirements; the heat transfer oil in the cooling row (503) absorbs the heat of the graphite powder, and the fan (504) transports gas to the inside of the rotating cylinder (401) through the oxygen pipe (505) to provide air for assisting the combustion of impurities; Step 5: Turn on the second drive motor (8) to drive the drive shaft (602) of the screw conveyor (601) to rotate, and the graphite powder after preliminary cooling enters the cooling and transporting component (6) from the feed port (506); Step 6: The driving shaft (602) starts to rotate under the drive of the driving motor, thereby driving the double-thread cooling structure (10) in the screw conveying shell (605) to rotate, and the graphite powder is fed into the screw conveyor (601) from the feed port (506). As the double-thread cooling structure (10) rotates, the graphite powder is gradually pushed toward the discharge port (604); Step 7: The cooling oil enters the driving shaft (602) through the cooling oil inlet (14) of the rotary joint (603), and flows into the oil cooling blades (11) to exchange heat with the graphite powder, thereby reducing the temperature of the graphite powder. During the entire heat treatment process, the screw conveyor (601) continuously rotates to convey the graphite powder from the feed port (506) to the discharge port (604); Step 8: A magnetic frame (12) is provided at the discharge port (604). Multiple groups of magnetic rods (13) inside the magnetic frame (12) can attract and separate iron impurities in the graphite powder. As the graphite powder flows out, the impurities are adsorbed by the magnetic rods (13) and retained on the magnetic frame (12), thereby achieving further purification of the graphite powder.
