Description

Technical Field

[0002] As the name suggests, natural graphite powder is a powdered object processed from natural ore. Natural graphite powder can be used in a variety of industrial fields, including refractory materials, conductive materials, and lubricating materials.

[0003] A patent with an existing announcement number of CN118320956B discloses a natural graphite powder airflow shaping device, including a shell, the inner wall of which is fixedly connected to a cleaning frame, and the bottom end of the cleaning frame is provided with a cleaning screw. By arranging a rotating brush, a rotating guide column slides through a double-helix rotating guide groove to drive the rotating cylinder to rotate, and the rotation of the rotating cylinder drives the rotating brush to slide along the outer wall of the diverter grille to scrape off impurities attached to the outer wall of the diverter grille.

[0004] During use, the above-mentioned technical solution cleans the outside of the diverter grid by a rotating brush to prevent impurities from adhering to the outside of the diverter grid.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 10As shown, a natural graphite powder airflow shaping device described in an embodiment of the present invention comprises a shaping box 1, supersonic airflow nozzles 11 are installed around the bottom of the shaping box 1, a feeding assembly 2 is installed in the middle of one side of the shaping box 1, and the top of the shaping box 1 is rotatably connected to a grading box 3, one end of the grading box 3 is provided with a discharge port 33, and the end of the grading box 3 away from the discharge port 33 is provided with a grading motor 31, the grading motor 31 is installed outside the shaping box 1, a gear is fixed at the end of the rotating shaft of the grading motor 31, and a gear is also fixed at the end of the grading box 3 away from the discharge port 33, the gear of the grading motor 31 is meshed with the gear of the grading box 3, and the outer side of the grading box 3 is provided with grading gears at equal intervals. Hole 32, a connection box 43 is provided on one side of the grading box 3, a cleaning block 431 is slidably connected inside the connection box 43, electric telescopic rods 432 are fixed on both sides of the connection box 43, the other end of the electric telescopic rod 432 is fixedly connected to the cleaning block 431, the outer diameter of the cleaning block 431 matches the inner diameter of the grading hole 32, a baffle 5 is provided on the side of the grading box 3 close to the connection box 43, a cleaning brush 51 is rotatably connected below the baffle 5, a second motor 52 is installed on one end of the baffle 5, a gear is fixed on the end of the rotating shaft of the second motor 52, a toothed disc is fixed on one end of the cleaning brush 51 close to the second motor 52, and the gear of the second motor 52 is meshed with the toothed disc of the cleaning brush 51; In the production process of natural graphite powder, it is necessary to process the graphite powder into the required shape and particle size. During the processing, the natural graphite powder to be processed is placed in the hopper of the feeding component 2, and then the supersonic airflow nozzle 11 is input with supersonic airflow through the external air supply equipment. At the same time, the feeding component 2 transports the natural graphite powder in the hopper to the inside of the shaping box 1, and the graphite powder falls to the bottom of the shaping box 1. At this time, the airflow blown out by multiple supersonic airflow nozzles 11 can blow the fallen graphite powder toward the top of the shaping box 1. At the same time, the feeding component 2 continues to transport the graphite powder to the shaping box 1. At this time, the blown graphite powder collides with the graphite powder currently transported to the inside of the shaping box 1, and the graphite powder can be shaped by the collision. When the external air supply is started, The equipment starts the grading motor 31 to drive the grading box 3 to rotate while supplying air to the supersonic airflow nozzle 11. At this time, the grading box 3 drives the grading hole 32 to rotate. During the rotation, centrifugal force is generated inside the grading box 3. The airflow ejected from the supersonic airflow nozzle 11 will generate centripetal force due to the viscosity of the airflow. When the centrifugal force inside the grading box 3 is greater than the centripetal force of the airflow from the supersonic airflow nozzle 11, the graphite powder particles in the airflow that are larger than the inner diameter of the grading hole 32 are classified outside the grading box 3, and the graphite powder particles that are smaller than the inner diameter of the grading hole 32 enter the inside of the grading box 3. Then, the grading box 3 can transport the graphite powder with the required outer diameter to the inside of the bag dust removal equipment through the discharge port 33 to collect the graphite powder. In this way, the natural graphite powder can be shaped; During the process of the grading box 3 sucking the natural graphite powder, a certain amount of dust will remain on the surface of the grading box 3 and the inner wall surface of the grading hole 32. After the dust accumulates for a long time, the weight of the grading box 3 will increase, affecting the rotation of the grading box 3. At the same time, the dust accumulation inside the grading hole 32 will cause the hole diameter to become smaller. At this time, the outer diameter of the graphite powder particles that can pass through the grading hole 32 and enter the grading box 3 will be affected, resulting in a large difference in the outer diameter of the graphite powder particles after some shaping. In order to solve this problem, it is necessary to clean the grading box 3 and the grading hole 32 after use. During the cleaning process, the connecting box 43 is moved to a position close to the inner wall of the grading box 3, and the cleaning brush 51 is moved to a position close to the outer wall of the grading box 3. Then, the grading motor 31 is started to drive the grading box 3 to rotate at a low speed. When the grading box 3 rotates to the position where the grading hole 32 is aligned with the electric telescopic rod 432, the electric telescopic rod 432 is started to push the cleaning block 431 out of the inside of the connecting box 43 The cleaning block 431 then enters the interior of the grading hole 32. At this time, the cleaning block 431 can push the dust accumulated in the grading hole 32 out to the outside. The outer material of the cleaning block 431 is rubber. When there is a small error in the position of the cleaning block 431 and the grading hole 32, the rubber material can adapt by deformation. After ejection, the electric telescopic rod 432 drives the cleaning block 431 to reset, and the grading box 3 drives the grading hole 32 to rotate to the next station. The above action is repeated to clean the interior of multiple grading holes 32. At the same time, the second motor 52 is started to drive the cleaning brush 51 to rotate in the same direction as the grading box 3. At this time, the cleaning brush 51 can sweep the dust outside the grading box 3. After cleaning, the connecting box 43 and the baffle 5 are moved. At this time, the connecting box 43 and the baffle 5 do not affect normal use. In this way, the outer side of the grading box 3 and the inner side of the grading hole 32 can be cleaned at the same time to prevent the aperture change of the grading hole 32 from affecting the uniformity of the outer diameter of the graphite powder after shaping.

[0024] like Figures 1 to 6 As shown, the grading box 3 is rotatably connected with a support rod 41 inside, and a first support frame 4 is fixed to one end of the support rod 41 close to the grading motor 31, and the first support frame 4 is fixedly connected to the shaping box 1, and the other end of the support rod 41 is fixedly connected to the inner wall of the grading box 3 through a bearing, and a rotating rod 411 is rotatably connected to the inside of the support rod 41, and two toothed discs are fixed to the outside of the rotating rod 411, and a threaded sleeve 413 is fixed on both sides of the connecting box 43 close to one end of the support rod 41, and a threaded rod 412 is threadedly connected to the inside of the support rod 41 at one end of the threaded sleeve 413, and a gear is fixed to one end of the threaded rod 412 away from the threaded sleeve 413, and the gear of the threaded rod 412 is meshed with the toothed disc of the rotating rod 411, and a first motor 42 is installed at one end of the shaping box 1 below the grading motor 31, and the end of the rotating shaft of the first motor 42 is fixedly connected to one end of the rotating rod 411; The first motor 42 is then turned to move the first and second motors 431 to move the first and second motors 432 back and forth, and the second and second motors 433 are turned to move the first and second motors 434 back and forth, respectively.

[0025] like Figures 1 to 6 As shown, the first support frame 4 is internally rotatably connected with a transmission rod 44, and a bevel gear is fixed to one end of the transmission rod 44 close to the first motor 42, and a bevel gear is fixed to the outside of one end of the rotating rod 411 close to the first motor 42, and the bevel gear of the transmission rod 44 is meshed and connected with the bevel gear of the rotating rod 411, and a sliding cavity is opened inside the first support frame 4, and a sliding sleeve 441 is slidably connected inside the sliding cavity, and the sliding sleeve 441 is threadedly connected to the transmission rod 44, and connecting shafts 514 are fixed to both ends of the baffle 5, and the connecting shaft 514 is rotatably connected to the sliding sleeve 441; When the connecting box 43 moves, the cleaning brush 51 needs to be moved to a position close to the outer side of the grading box 3. In the initial state, the cleaning brush 51 is in a position away from the grading box 3. When the rotating rod 411 rotates, the transmission rod 44 is driven to rotate synchronously with the rotating rod 411 through the bevel gear transmission. At this time, the transmission rod 44 can drive the sliding sleeve 441 to move inside the sliding cavity of the first support frame 4, and the sliding sleeve 441 drives the baffle 5 to approach the grading box 3 through the connecting shaft 514. When the connecting box 43 is close to the inner wall of the grading box 3, the baffle 5 drives the cleaning brush 51 to approach the outer wall of the grading box 3, and then cleaning can be carried out. After cleaning, when the blowing rack 53 is reset, the transmission rod 44 rotates in the opposite direction to drive the cleaning brush 51 to reset.

[0026] like Figures 1 to 7 As shown, a second support frame 442 is fixed to the side of the shaping box 1 away from the first support frame 4, a sliding cavity is also opened inside the second support frame 442, a sliding sleeve 441 is also slidably connected inside the sliding cavity, a sliding rod 443 is fixed inside the sliding cavity of the second support frame 442, and the sliding rod 443 is slidably connected to the sliding sleeve 441 on one side of the second support frame 442; During the movement of the baffle 5, in order to ensure the stability of the baffle 5, the connecting shaft 514 at the other end of the baffle 5 will slide inside the sliding cavity of the second support frame 442. At this time, the sliding rod 443 can support the connecting shaft 514, so that the baffle 5 can remain stable during the movement.

[0027] like Figures 1 to 7 As shown, a coil spring 511 is fixed to one side of the sliding sleeve 441 close to the connecting shaft 514, and the other end of the coil spring 511 is fixedly connected to the connecting shaft 514; During use, the coil spring 511 supports the sliding sleeve 441 and the connecting shaft 514, so as to keep the baffle 5 in a stable state during use.

[0028] like Figures 1 to 7 As shown, a storage cavity 12 is provided on one side of the shaping box 1, a plurality of teeth 512 are fixed at equal intervals on the top of the sliding cavity of the first support frame 4 and the second support frame 442 near the storage cavity 12, and a plurality of teeth 512 are fixed at equal intervals on the outside of the cleaning brush 51 near the coil spring 511, and the maximum rotation angle of the baffle 5 is 90°, and the baffle 5 can be engaged with the storage cavity 12 after rotating 90°; When the sliding sleeve 441 drives the baffle 5 away from the grading box 3, it will move toward the storage chamber 12. When the connecting shaft 514 moves to the position of the teeth 512, the baffle 5 is close to the storage chamber 12. Then, the baffle 5 can be rotated 90° counterclockwise under the meshing action of the teeth 512 and the connecting shaft 514. After the baffle 5 rotates 90°, the cleaning brush 51 is placed inside the storage chamber 12. At the same time, the baffle 5 is engaged with the opening of the storage chamber 12, so that graphite powder will not enter the inside of the cleaning brush 51 during shaping inside the shaping box 1, thereby preventing graphite powder from entering the inside of the cleaning brush 51 and affecting the cleaning effect.

[0029] like Figures 1 to 10 As shown, the bottom end of the baffle 5 is rotatably connected to a blow rack 53, a plurality of nozzles are evenly spaced on one side close to the cleaning brush 51, and the end of the blow rack 53 away from the second motor 52 is rotatably connected to a connecting pipe 531; When in use, the connecting pipe 531 is connected to an external air supply device, and the air supply device inputs airflow into the blowing rack 53 through the connecting pipe 531. The airflow is ejected through the nozzle of the blowing rack 53. The airflow ejected from the nozzle can perform preliminary cleaning on the surface of the grading box 3 and the inside of the grading hole 32, which can reduce the brushing amount of the cleaning brush 51 and make the cleaning brush 51 sweep the surface of the grading box 3 more cleanly.

[0030] like Fig. 9 As shown, the top end of the blowing frame 53 near the connecting pipe 531 is rotatably connected to a push rod 532, the bottom end of the baffle 5 near the push rod 532 is fixed with a guide frame 533, the push rod 532 runs through the inside of the guide frame 533, and the end of the cleaning brush 51 near the push rod 532 is fixed with a ratchet 513; When the cleaning brush 51 sweeps the surface of the grading box 3, dust may remain inside the cleaning brush 51, so the dust inside the cleaning brush 51 needs to be cleaned. During the rotation of the cleaning brush 51, the ratchet 513 is driven to rotate. When the ratchet 513 rotates, it pushes the push rod 532 to move through the outer wedge block. At this time, the push rod 532 pushes the blowing rack 53 to rotate. When the blowing rack 53 rotates, the nozzle can be turned to the position of the cleaning brush 51. At this time, the nozzle of the blowing rack 53 can spray airflow to the cleaning brush 51 to clean the inside of the cleaning brush 51.

[0031] like Fig. 9 As shown, a spring 534 is fixed to one side of the guide frame 533 away from the connecting pipe 531, and the other end of the spring 534 is fixedly connected to the push rod 532; After one of the wedge blocks of the ratchet 513 pushes the push rod 532, the ratchet 513 will rotate to the next wedge block. At this time, the push rod 532 loses its thrust, and the spring 534 drives the push rod 532 to reset, so that the blowing rack 53 can be reset. With this reciprocating action, the blowing rack 53 can blow airflow in a fan shape to the surface of the grading box 3, and clean the inside of the cleaning brush 51 at the same time.

[0032] like Fig.10 As shown, a blocking block 54 is fixed to the bottom end of the baffle 5 near the cleaning brush 51, and the top end of the cleaning brush 51 is close to the bottom end of the baffle 5; When the cleaning brush 51 rotates, the blocking block 54 will block the bristles of the cleaning brush 51. At this time, the bristles of the cleaning brush 51 will be deformed. When the deformed bristles rotate away from the position of the blocking block 54, they will quickly restore their shape. At this time, the bristles will have a striking effect on the outside of the grading box 3, making it easier for the cleaning brush 51 to clean the outer surface of the grading box 3.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
