Description

Technical Field

[0001] The utility model relates to the technical field of graphite powder heat treatment, in particular to a spiral conveying structure for removing fibers from graphite powder. Background Art

[0002] Graphite powder heat treatment is a key process link and has wide applications in multiple industrial fields. During the heat treatment process, the conveying and temperature control of graphite powder are core issues. Traditional conveying methods may have problems such as low conveying efficiency and inaccurate temperature control, resulting in poor heat treatment effects of graphite powder. Therefore, it is particularly important to develop an efficient and stable conveying structure for graphite powder heat treatment.

[0003] Although the existing spiral conveying structures can, to a certain extent, achieve the conveying of graphite powder, in a high-temperature environment, there are still deficiencies in aspects such as sealing performance, cooling effect, and magnetic separation. These problems not only affect the conveying efficiency but may also have a negative impact on the quality of graphite powder. In the production and application processes of graphite powder, the presence of fiber impurities is also an urgent problem to be solved. Due to their flexibility and winding properties, fiber impurities are prone to entanglement with graphite powder, affecting the quality and application effects of graphite powder. Summary of the Utility Model

[0004] To solve some problems existing in the above-mentioned prior art, the utility model provides a spiral conveying structure for removing fibers from graphite powder to address the deficiencies in the prior art.

[0005] To achieve the above object, the utility model provides a spiral conveying structure for removing fibers from graphite powder, including a spiral conveying structure body. The spiral conveying structure body includes a screw conveyor. One end of the screw conveyor is provided with a driving motor. The central position inside the screw conveyor is provided with a driving shaft. One end of the driving shaft is connected to the driving motor, and the other end of the driving shaft is provided with a rotary joint. The screw conveyor is provided with a spiral conveying housing in cooperation with the driving shaft. The two ends of the screw conveyor are respectively provided with a feeding port and a discharging port.

[0006] As a further improvement of the utility model, in order to effectively prevent the leakage of high-temperature oil fluid and ensure the cleanliness and safety of the conveying environment, a sealing structure is cooperatively provided between the rotary joint and the spiral conveying housing. The rotary joint is connected with a cooling oil inlet and a high-temperature oil outlet.

[0007] As a further improvement of the utility model, in order to provide multiple sealing guarantees and enhance the reliability of sealing, the sealing structure includes a sealing bearing, and the sealing bearing is cooperatively provided with a first sealing disc and a second sealing disc. The first sealing disc and the second sealing disc are stacked in sequence, and the second sealing disc is arranged on the spiral conveying housing.

[0008] As a further improvement of the present utility model, in order to enable the cooling oil to circulate fully and effectively reduce the temperature of the drive shaft, the drive shaft is hollow, and a sealing plate is arranged between the drive shaft and the drive motor, and the sealing plate is welded to the drive shaft.

[0009] As a further improvement of the present utility model, in order to enable the cooling oil to circulate fully and exchange heat with the graphite powder to effectively reduce the temperature of the drive shaft, a threaded cooling structure is cooperatively arranged on the drive shaft. The threaded cooling structure includes several groups of oil cooling blades. The interior of the oil cooling blades is hollow and is communicated with the drive shaft.

[0010] As a further improvement of the present utility model, in order to attract and separate iron impurities in the graphite powder and improve the purity of the graphite powder, a magnetic rack is arranged at the discharge port. A plurality of groups of magnetic rods are arranged inside the magnetic rack, and the magnetic rods are arranged in a multi-row and multi-column structure.

[0011] When the present utility model works, before starting, a comprehensive inspection is carried out on the screw conveying structure to ensure that all components (such as the drive motor, screw conveyor, drive shaft, rotary joint, screw conveying housing, feed port, discharge port, magnetic rack, etc.) are intact, the connections are firm, there is no foreign matter blockage, the power supply is connected, and the drive motor is started. The drive motor starts to rotate and transmits power to the drive shaft through the sealing plate; the drive shaft starts to rotate driven by the drive motor, and then drives the threaded cooling structure in the screw conveying housing to rotate. The graphite powder is fed into the interior of the screw conveyor from the feed port. As the threaded cooling structure rotates, the graphite powder is gradually pushed towards the discharge port direction; the cooling oil enters the interior of the drive shaft through the cooling oil inlet of the rotary joint, circulates to the oil cooling blades, and exchanges heat with the graphite powder, thereby reducing the temperature of the graphite powder. During the entire heat treatment process, the screw conveyor continuously rotates to convey the graphite powder from the feed port to the discharge port. A magnetic rack is arranged at the discharge port. The plurality of groups of magnetic rods inside the magnetic rack can attract and separate the iron impurities in the graphite powder. As the graphite powder flows out, the impurities are adsorbed by the magnetic rods and remain on the magnetic rack, thus realizing the effective separation of the impurities.

[0012] The beneficial effects of the present utility model are as follows: The present utility model provides a spiral conveying structure for removing fibers from graphite powder. By optimizing the design of the screw conveyor, the graphite powder is conveyed more smoothly during the conveying process, reducing clogging and retention phenomena, thereby improving the conveying efficiency; the design of the drive shaft reduces the weight of the drive shaft while maintaining sufficient strength, making the rotation more stable and further enhancing the conveying efficiency; the sealing structure between the rotary joint and the spiral conveying housing effectively prevents the leakage of high-temperature oil, ensuring the cleanliness and safety of the conveying environment. The combined use of the sealing bearing, the first sealing disc, and the second sealing disc provides multiple sealing guarantees and enhances the reliability of the seal; the combination of the drive shaft and the threaded cooling structure enables the cooling oil to circulate fully and exchange heat with the graphite powder through the oil cooling blades, effectively reducing the temperature of the drive shaft; the magnetic rack design at the discharge port can attract and separate iron impurities in the graphite powder, improving the purity of the graphite powder. The multiple magnetic rods are arranged in multiple rows and columns, enhancing the adsorption capacity of the magnetic rack and ensuring the effective removal of impurities; the connections between the components are firm and reliable, easy to maintain, and reduce the usage cost.
