[0013] Working principle: When producing spherical graphite, first the preliminary crushing mechanism of the whole device is started, and the staff continuously puts the block graphite material to be processed into the inlet of the top processing box from the inlet on the top processing box. After the block graphite material enters the top processing box, the driving motor 2 on the top processing box is started, and the rotating shaft of the driving motor 2 drives the driving rod on it to rotate synchronously while rotating, and the driving rod drives the pulley on it to rotate while rotating. The pulley drives the pulley on the other side and the driving rod on it to rotate synchronously through the connecting belt. The driving rod drives the cam seat on it to rotate while rotating. The cam seat rotates while the raised part on it synchronously squeezes the extrusion plate in the top processing box to move synchronously toward the middle. The extrusion plate is pushed by the cam seat on the driving rod and drives the extrusion seat on it to move synchronously toward the middle, thereby extruding and crushing the graphite material entering between the extrusion plates, and the extrusion plate in the top processing box moves synchronously toward the middle while driving the connecting spring on it to open, and the extrusion plate completes the stone in the top processing box. After the graphite material is extruded and crushed, the top thrust of the connecting spring disappears, and the connecting spring drives the extrusion plate in the top processing box to reset, thereby completing the preliminary crushing of the graphite material; then the crushing and smoothing mechanism is started, and the graphite material processed by the preliminary crushing mechanism enters the bottom processing box through the crushing outlet at the bottom of the top processing box and the connecting box, at this time, the driving motor 1 on the bottom processing box is started, and the rotating shaft of the driving motor 1 drives the center rod in the bottom processing box to rotate synchronously while rotating, and the center rod drives the triangular base on it to rotate while being driven to rotate, and the triangular base drives the crushing seat on it to rotate synchronously while rotating, and the crushing seat crushes the fallen graphite material block again while rotating, and while the crushing seat rotates, it drives the metal sphere in the bottom processing box to move synchronously, and the metal sphere moves and changes position with the graphite material block, and the metal sphere rubs the edges and protrusions on the graphite material block through the metal sphere, so that the graphite material block is processed into a relatively smooth spherical graphite, thereby completing the crushing and smoothing of the graphite material;During the process of crushing the graphite material, the dust purification mechanism is started synchronously. During the process of crushing the graphite material, the exhaust fan on the dust treatment box is started. The exhaust fan pumps the air in the dust treatment box out, so that a negative pressure state is formed inside the dust treatment box. Therefore, the powder generated by the graphite crushing in the connection box will be driven by the air inside and enter the dust treatment box. And the solid graphite particle material is prevented from entering the dust treatment box through the solid partition net on the dust treatment box. Then, the dust carried in the air entering the dust treatment box is initially filtered for the graphite dust in the air through the filter cotton board on the fixed frame in sequence. Then, the circulating filter pump on the storage box is started. The circulating filter pump supplies water source to the water curtain row on the dust treatment box through the connecting pipe. Then, a water curtain is formed through the water curtain row to purify the filtered air again, and the floating graphite dust residues in the air are treated through the water curtain. After that, the water of the water curtain is collected through the storage box, and then it is filtered again through the circulating filter pump on it and recycled. Finally, the air after multiple purification treatments is discharged into the external environment by the driving of the exhaust fan, thus completing the multiple purification treatment of the dust during the graphite crushing process; finally, the finished product discharging mechanism is started. When the graphite material blocks in the bottom treatment box are processed to the extent that they can be discharged, the staff pulls out the blocking plug from the opening of the discharge box through the handle rod. As the triangular base in the bottom treatment box rotates continuously, the spherical graphite blocks after the treatment in the bottom treatment box also enter the discharge channel of the discharge box and are discharged. At the same time, the discharge channel on the discharge box is started. When the discharge channel is started, it vibrates, accelerating the discharge of the ball-milled graphite in the discharge channel. And the spherical graphite blocks in the discharge box are screened through the sieve holes on the sieve plate. On the one hand, it can improve the uniformity of the discharged volume of the spherical graphite blocks. On the other hand, it can also prevent the metal spheres in the bottom treatment box from being processed together with the spherical graphite blocks. Finally, the spherical graphite blocks after the collaborative treatment of the sieve plate and the vibrator enter the collection device for centralized collection, thus completing the collection and treatment of the finished spherical graphite.;

[0014] The present invention provides a crushing and processing device for spherical graphite production. It has the following beneficial effects: 1. By adding and setting the preliminary crushing mechanism, when processing the graphite material, on the one hand, the volume of the graphite material can be reduced through preliminary crushing to prevent the equipment from being blocked by the graphite material with a large volume, thus facilitating the subsequent processing of the graphite material. On the other hand, it can also reduce the subsequent processing difficulty of the graphite material, thereby improving the processing work efficiency of the graphite material.

[0015] 2. By adding and setting a crushing and rounding mechanism, the present invention conducts secondary crushing and rounding treatment on the preliminarily crushed graphite material. Firstly, the crushing and rounding mechanism can further refine and homogenize the massive graphite material, ensuring that the particle size after crushing is more uniform, thereby improving the quality and performance of the product. Secondly, through the rounding treatment, the sharp edges and irregular surfaces between particles can be effectively reduced, the friction and wear between particles can be decreased, the service life of the overall product can be extended, and at the same time, it is also convenient for the processing of spherical graphite.

[0016] 3. Through the crushing and rounding treatment of the graphite material, the present invention also helps to further improve the fluidity and compactness of graphite particles, enhance their processing performance and forming efficiency in applications. In addition, this mechanism can reduce dust generation and product loss during the crushing process, lower energy consumption and environmental pollution, meeting the requirements of sustainable development.

[0017] 4. By adding and setting a dust purification mechanism, during the crushing process of the graphite material, the dust generated during the crushing process is treated through multiple filtration and purification. This can not only prevent the dust from polluting the surrounding environment with the air flow but also avoid the surrounding workers inhaling graphite dust and affecting their physical health, with good environmental protection.

[0018] 5. By adding and setting a finished product discharging mechanism, after the processing of spherical graphite is completed, through the method of vibration screening, not only can the processed spherical graphite be discharged and centrally collected, but also the volume of spherical graphite can be screened through a sieve plate or other means, facilitating the direct utilization of subsequent spherical graphite.

[0023] When the preliminary crushing mechanism is started, the staff continuously feeds the required massive graphite material into the inside of the feeding port 13 on the top treatment box 6. After the massive graphite material enters the top treatment box 6, the driving motor two 5 on the top treatment box 6 is started, and the rotating shaft of the driving motor two 5 drives the driving rod 22 thereon to rotate synchronously while rotating.

[0024] The preliminary crushing mechanism further includes extrusion plates 27. Extrusion plates 27 are arranged on both sides in the middle of the top treatment box 6.

A crushing material outlet 24 is opened in the middle of the bottom end of the top treatment box 6.

[0025] While the driving rod 22 is rotating, it drives the pulley 18 thereon to rotate. While the pulley 18 is rotating, it drives the pulley 18 on the other side and the driving rod 22 thereon to rotate synchronously through the connecting belt 19. While the driving rod 22 is rotating, it drives the cam seat 21 thereon to rotate. While the cam seat 21 is rotating, the protruding part thereon synchronously squeezes the extrusion plate 27 in the top treatment box 6 to move synchronously towards the middle. While the extrusion plate 27 is being pushed by the cam seat 21 on the driving rod 22, it drives the extrusion seats 26 thereon to move synchronously towards the middle, thereby squeezing and crushing the graphite material entering between the extrusion plates 27.

[0026] And while the extrusion plates 27 in the top treatment box 6 move synchronously towards the middle, it drives the connecting springs 20 thereon to open. After the extrusion plates 27 in the top treatment box 6 complete the extrusion and crushing treatment of the graphite material, the top thrust received by the connecting springs 20 disappears, and the connecting springs 20 drive the extrusion plates 27 in the top treatment box 6 to reset, thereby completing the preliminary crushing treatment of the graphite material.

[0027] Please refer to the attached Figure 5 , the crushing and rounding mechanism, which is arranged inside the bottom treatment box 3 and is used for further crushing the graphite material processed by the preliminary crushing mechanism and rounding the edges and corners of the graphite material blocks; The crushing and rounding mechanism includes a connecting box 4.

[0029] When the smooth crushing mechanism is started, the graphite material processed by the preliminary crushing mechanism enters the bottom processing box 3 through the crushing outlet 24 at the bottom of the top processing box 6 and the connecting box 4. At this time, the driving motor 2 on the bottom processing box 3 is started, and the rotating shaft of the driving motor 2 drives the center rod 32 in the bottom processing box 3 to rotate synchronously while rotating. The center rod 32 drives the triangular base 29 thereon to rotate while being driven to rotate. The triangular base 29 drives the crushing seat 28 thereon to rotate synchronously while rotating. The crushing seat 28 crushes the fallen graphite material blocks again while rotating.

[0030] While the crushing seat 28 rotates, it drives the metal sphere 31 in the bottom processing box 3 to move synchronously.

[0032] When the dust purification mechanism is started, during the process of pulverizing the graphite material, the exhaust fan 17 on the dust treatment box 8 is started. The exhaust fan 17 sucks out the air inside the dust treatment box 8, thereby creating a negative pressure state inside the dust treatment box 8. Therefore, the powder generated by graphite pulverization in the connection box 4 will be driven by the air inside it into the dust treatment box 8, and the solid graphite particle material is prevented from entering the dust treatment box 8 through the solid partition net 39 on the dust treatment box 8. Then, the dust carried in the air entering the dust treatment box 8 is preliminarily filtered for the graphite dust in the air through the filter cotton board 37 on the fixed frame 38 in sequence.

[0033] The dust purification mechanism further includes an exhaust fan 17. The exhaust fan 17 is arranged on the side of the dust treatment box 8 away from the connection box 4.

Then, a water curtain is formed through the water curtain row 7 to purify the filtered air again, and the floating graphite dust residues in the air are treated through the water curtain. After that, the water of the water curtain is collected through the storage box 9, and then it is filtered again through the circulating filter pump 14 on it and recycled. Finally, the air after multiple purification treatments is discharged into the external environment by the driving of the exhaust fan 17, thus completing the multiple purification treatment of the dust during the graphite pulverization process.

[0035] Please refer to the attached Figure 6 , the finished product discharging mechanism, which is arranged on one side of the bottom treatment box 3 and is used for discharging the spherical graphite material after being processed by the pulverizing and rounding mechanism.

As the triangular base 29 in the bottom processing box 3 continues to rotate, the spherical graphite blocks after processing in the bottom processing box 3 also enter the discharge channel 16 of the discharge box 15 for discharge. At the same time, the discharge channel 16 on the discharge box 15 is started, and the discharge channel 16 vibrates while starting, thereby accelerating the discharge of the spherical graphite in the discharge channel 16.

[0038] The spherical graphite blocks in the discharge box 15 are screened through the sieve holes 36 on the sieve plate 35. On the one hand, this can improve the uniformity of the volume of the spherical graphite blocks discharged, and on the other hand, it can prevent the metal spheres 31 in the bottom processing box 3 from being processed together with the spherical graphite blocks. Finally, the spherical graphite blocks after the coordinated processing by the sieve plate 35 and the vibrator 11 are collected in a collecting device, thereby completing the discharge, collection and processing of the finished spherical graphite.
