Description

Technical Field

[0001] This utility model relates to the field of graphite powder processing technology, and in particular to a graphite powder impurity removal device. Background Technology

[0002] Graphite powder impurity removal equipment plays a crucial role in the graphite powder purification process. Its main function is to remove various impurities mixed in with the graphite powder, among which maghemite is a relatively common one. Maghemite is formed from trace metal elements contained in the graphite ore itself. During a series of processing steps such as mining, crushing, and grinding, these metal elements undergo an oxidation reaction with oxygen, thereby forming maghemite.

[0003] In the existing field of graphite powder impurity removal technology, the stirring adsorption method is a widely used approach for removing maghematite. However, this traditional stirring adsorption assembly has a significant drawback. After the magnetic rod completes its adsorption operation, the maghematite adsorbed on its surface needs to be manually removed. Because the magnetic rod tightly adsorbs a large number of maghematite particles during the adsorption process, and these particles are hard and irregularly shaped, operators are highly susceptible to hand injuries due to improper handling during manual cleaning. This not only poses a threat to the operator's personal safety but may also affect the purity of the graphite powder due to blood contamination, thereby reducing product quality. Furthermore, manual cleaning is inefficient and cannot meet the demands of large-scale industrial production for efficient and continuous impurity removal operations, thus limiting the improvement of production efficiency and economic benefits for graphite powder production and processing enterprises to some extent. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a graphite powder impurity removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A graphite powder impurity removal device includes a mixing tank and a mounting cover. The mixing tank and the mounting cover are connected by a fixing mechanism. A rotating frame is provided on the mounting cover via a rotating groove. An external motor connected to the rotating frame is provided on the mounting cover. A stirring shaft is provided on the rotating frame. Multiple magnetic rods are mounted on the stirring shaft. A moving groove is provided on the rotating frame. An annular cavity is provided inside the rotating frame. A screw extending into the annular cavity is rotatably provided in the moving groove. A rotating ring is provided in the annular cavity. The screw is connected to the rotating ring via a transmission mechanism. An internal motor is provided in the annular cavity. The internal motor is connected to the rotating ring via a rotating mechanism. A cleaning sleeve is fitted on each magnetic rod. Adjacent cleaning sleeves are connected by a connecting rod. The uppermost connecting rod is set in the moving groove by a limiting mechanism and threaded onto the screw.

[0007] Preferably, the fixing mechanism includes a plurality of fixing bolts disposed on the mounting cover, the plurality of fixing bolts being distributed at equal intervals around the circumference, and the outer wall of the mixing tank being provided with threaded connection grooves corresponding to the fixing bolts.

[0008] Preferably, the transmission mechanism includes a transmission gear mounted on a screw, and a lower gear ring that meshes with the transmission gear is mounted on the rotating ring.

[0009] Preferably, the rotating mechanism includes a drive gear mounted on the output shaft of the internal motor, and an upper gear ring that meshes with the drive gear is mounted on the rotating ring.

[0010] Preferably, the limiting mechanism includes a limiting rod installed in the moving groove, the limiting rod sliding through the connecting rod.

[0011] Preferably, the vertical cross-section of the rotating groove is cross-shaped, and the vertical cross-section of the rotating frame is also cross-shaped.

[0012] The beneficial effects of this utility model are:

[0013] 1. An external motor drives the stirring shaft and magnetic rod to rotate inside the mixing tank, ensuring that the graphite powder makes full contact with the magnetic rod during the stirring process. The magnetic rod effectively adsorbs magnetic impurities such as iron filings from the graphite powder. This simultaneous stirring and magnetic adsorption method greatly improves the efficiency and effectiveness of impurity removal. In large-scale graphite powder production and processing, this method can rapidly improve the purity of graphite powder, reduce the burden of subsequent processing steps, and increase overall production efficiency.

[0014] 2. The multiple magnetic suction rods can magnetically remove impurities from graphite powder at different positions in the mixing tank, avoiding the problem of incomplete local removal of impurities, ensuring the overall purity and uniformity of graphite powder, and contributing to the stability of the quality of subsequent graphite product production.

[0015] 3. The self-cleaning function of this device enables automated operation. After the impurity removal process is completed, the internal motor can be started to complete the cleaning of the magnetic suction rod, reducing the time and labor intensity of manual operation and improving the degree of automation of the production process.

[0024] A graphite powder impurity removal device includes a mixing tank 1 and a mounting cover 2. The mixing tank 1 and the mounting cover 2 are connected by a fixing mechanism. A rotating frame 5 is provided on the mounting cover 2 through a rotating groove. An external motor 4 connected to the rotating frame 5 is provided on the mounting cover 2. A stirring shaft 6 is provided on the rotating frame 5. Multiple magnetic rods 7 are installed on the stirring shaft 6. A moving groove 13 is provided on the rotating frame 5. An annular cavity 8 is provided inside the rotating groove 13. A screw 14 extending into the annular cavity 8 is rotatably provided in the moving groove 13. A rotating ring 9 is provided in the annular cavity 8. The screw 14 is connected to the rotating ring 9 through a transmission mechanism. An internal motor 10 is provided in the annular cavity 8. The internal motor 10 is connected to the rotating ring 9 through a rotating mechanism. A cleaning sleeve 19 is fitted on each magnetic rod 7. Adjacent cleaning sleeves 19 are connected by a connecting rod 18. The uppermost connecting rod 18 is set in the moving groove 13 by a limiting mechanism and is threaded onto the screw 14.

[0025] The fixing mechanism includes multiple fixing bolts 3 mounted on the mounting cover 2. These bolts 3 are evenly spaced circumferentially, and the outer wall of the mixing tank 1 has threaded grooves corresponding to the fixing bolts 3. The evenly spaced circumferentially spaced fixing bolts 3 ensure a tight and stable connection. This connection method allows for easy removal of the mounting cover 2 when needed, enabling inspection, maintenance, or cleaning of the interior of the mixing tank 1.

[0026] The transmission mechanism includes a transmission gear 15 mounted on the screw 14, and a lower gear ring 16 meshing with the transmission gear 15 mounted on the rotating ring 9. The rotation mechanism includes a drive gear 11 mounted on the output shaft of the internal motor 10, and an upper gear ring 12 meshing with the drive gear 11 mounted on the rotating ring 9. When the internal motor 10 starts, it can directly drive the drive gear 11 to rotate. The drive gear 11 can drive the rotating ring 9 to rotate via the upper gear ring 12. The rotating ring 9 can drive the lower gear ring 16 to rotate. The lower gear ring 16 can drive the transmission gear 15 to rotate. The transmission gear 15 can drive the screw 14 to rotate.

[0027] The limiting mechanism includes a limiting rod 17 installed in the moving groove 13, which slides through the connecting rod 18. The limiting rod 17 can limit the connecting rod 18 and prevent it from rotating with the screw 14.

[0028] The vertical cross-section of the rotating groove is cross-shaped, and the vertical cross-section of the rotating frame 5 is also cross-shaped. These shapes ensure that the rotating frame 5 can rotate within the rotating groove, but will not move vertically and fall out of the rotating groove.

[0029] When using this invention, the graphite powder that needs to be cleaned is placed in the mixing tank 1, and the mounting cover 2 is installed on the mixing tank 1. The mounting cover 2 is fixedly installed by means of multiple fixing bolts 3. The cleaning sleeve 19 is initially attached to the stirring shaft 6. At this time, the external motor 4 is started, which can drive the rotating frame 5 to rotate. The rotation of the rotating frame 5 can drive the stirring shaft 6 and the magnetic suction rod 7 to rotate, thereby realizing the stirring treatment of graphite powder. The magnetic suction rod 7 can also attract iron filings.

[0030] After processing, unscrew the fixing bolt 3 to release the installation cover 2. After removing the installation cover 2, start the inner motor 10. The inner motor 10 drives the rotating ring 9 to rotate through the drive gear 11 and the upper gear ring 12. The rotating ring 9 drives the screw 14 to rotate through the lower gear ring 16 and the transmission gear 15. When the screw 14 rotates, it can drive the cleaning sleeve 19 to move on the magnetic stick 7 through the connecting rod 18, which can scrape off the iron filings adsorbed on it for collection.
