[0035] Please see Figure 1-6 A screening and crushing device for graphite raw material production includes a base 1, a crushing tank 2 fixedly connected to one side of the top of the base 1, a feed inlet 3 fixedly connected to one side of the outer side of the crushing tank 2, a crushing blade 4 symmetrically rotatably connected to the upper part of the inside of the base 1, a funnel 5 fixedly connected to the lower part of the inside of the base 1, a discharge pipe 6 fixedly connected to the bottom of the funnel 5 extending to the outside of the base 1, a screening cylinder 7 rotatably connected to the outside of the discharge pipe 6 through a rotary joint, two sets of screen holes 8 of different sizes are equally spaced on both sides of the outside of the screening cylinder 7, and a transmission assembly is provided on the outside of the base 1.

[0036] Specifically, the transmission assembly includes a transmission gear 9 and a linkage unit. The transmission gear 9 is symmetrically rotatably connected to the top of the base 1. One end of each of the two crushing blades 4 extends to the top of the base 1 and is fixedly connected to the corresponding transmission gear 9. A motor 10 is fixedly connected to one side of the top of the base 1 via a mounting plate. The output end of the motor 10 is fixedly connected to one of the transmission gears 9. The screening cylinder 7 can be rotated via the linkage unit.

[0037] Through the above technical solution, the motor 10 is first started by an external controller, and the graphite raw material is fed into the crushing tank 2 through the feed inlet 3. The output end of the motor 10 drives the corresponding transmission gear 9 and the first pulley 11 to rotate. Then, through the meshing relationship between the two transmission gears 9, the two crushing blades 4 can be driven to rotate, thereby crushing the graphite raw material. The crushed graphite raw material falls to the top of the funnel 5, and then is conveyed to the inside of the screening cylinder 7 through the discharge pipe 6. At the same time as the first pulley 11 rotates, the second pulley 13 and the rotating shaft 12 can be driven to rotate through the transmission belt 14, so that the rotating shaft 12 drives the first bevel gear 15 at the bottom to rotate. The first bevel gear 15 then drives the second bevel gear 16 and the screening cylinder 7 to rotate through the meshing relationship. During the rotation of the screening cylinder 7, the graphite raw material inside rolls along with it, so that the graphite raw material rolls along with the screen 7. The graphite raw material is sieved through two screens 8 of different sizes by centrifugal force combined with the propulsion of the screw conveyor blades towards the discharge port. Small graphite particles first pass through the smaller screen 8 and exit into the corresponding collection box 19. Then, medium-sized graphite particles pass through the larger screen 8 and exit into the corresponding collection box 19. Finally, large graphite particles enter the corresponding collection box 19 through the discharge port. This allows for precise sieving and collection of graphite particles at each stage, facilitating subsequent processing and application. The device first crushes the graphite raw material using symmetrically arranged crushing blades 4. The crushed graphite particles enter the screening cylinder 7 and are then automatically and precisely sieved through the screens 8 of different sizes, facilitating subsequent processing and application. This avoids the hassle of manual sieving after crushing, thus greatly improving work efficiency and reducing manpower burden.

[0038] Specifically, a support frame 17 is symmetrically fixedly connected to the top of the base 1 and the bottom of the screening cylinder 7. A ring 18 is fixedly connected to both sides of the outside of the screening cylinder 7. The ring 18 is slidably connected to the inside of the corresponding support frame 17. A discharge port is opened at the end of the screening cylinder 7 away from the discharge pipe 6. Multiple collection boxes 19 are placed on the top of the base 1 and below the screening cylinder 7, corresponding to the two screen holes 8 and the discharge port. A dust collection device 20 is installed on the top of the base 1 near the screening cylinder 7. A spiral conveyor blade is fixedly connected inside the screening cylinder 7.

[0039] Through the above technical solution, the dust collection device 20 can be activated by an external controller during the screening process to absorb the generated dust, thereby preventing dust from polluting the surrounding environment and causing workers to inhale it, thus improving the environmental performance of the device.

[0040] Specifically, the motor 10 and the dust collection device 20 are both electrically connected to an external controller. The blades of the two crushing blades 4 are staggered. Support feet are symmetrically fixed to both sides of the bottom of the crushing tank 2. The diameter of the first bevel gear 15 is smaller than the diameter of the second bevel gear 16.

[0041] Through the above technical solution, the motor 10 and the dust collection device 20 can be quickly controlled by the external controller, and the support feet can improve the stability of the crushing tank 2 during operation.

[0042] In operation, the motor 10 is first started via an external controller, and graphite raw material is fed into the crushing tank 2 through the feed inlet 3. The output of the motor 10 drives the corresponding transmission gear 9 and the first pulley 11 to rotate. The meshing relationship between the two transmission gears 9 drives the two crushing blades 4 to rotate, thereby crushing the graphite raw material. The crushed graphite raw material falls to the top of the funnel 5 and is then conveyed to the inside of the screening cylinder 7 through the discharge pipe 6. At the same time as the first pulley 11 rotates, the transmission belt 14 drives the second pulley 13 and the rotating shaft 12 to rotate, causing the rotating shaft 12 to drive the first bevel gear 15 at the bottom to rotate. The first bevel gear 15 then drives the second bevel gear 16 and the screening cylinder 7 to rotate through the meshing relationship. During the rotation of the screening cylinder 7, the graphite raw material inside rolls along with it. During the rolling process, the graphite raw material moves towards the discharge port through centrifugal force combined with the push of the spiral conveyor blades. During the movement, the graphite raw material is screened through two screens 8 of different sizes. Small graphite particles first pass through the screens 8. The graphite raw materials pass through the smaller sieve holes 8 and exit into the corresponding receiving box 19. Medium-sized graphite particles then pass through the larger sieve holes 8 and exit into the corresponding receiving box 19. Finally, large-sized graphite particles enter the corresponding receiving box 19 through the discharge port. This allows for precise screening and collection of graphite particles at each level, facilitating subsequent processing and application. The device first crushes the graphite raw materials using symmetrically arranged crushing blades 4. The crushed graphite particles then enter the screening cylinder 7 and are automatically and precisely screened through sieve holes 8 of different sizes, facilitating subsequent processing and application. This avoids the hassle of manual screening after crushing, greatly improving work efficiency and reducing manpower burden. During screening, the dust collection device 20 is activated by an external controller to absorb the generated dust, preventing dust pollution to the surrounding environment and inhalation by workers, thus improving the environmental performance of the device. The external controller allows for quick and easy control of the motor 10 and the dust collection device 20. The support feet enhance the stability of the crushing tank 2 during operation.
