Description

Technical Field

[0001] The present invention relates to the technical field of graphite processing equipment, and particularly relates to an efficient graphite crushing and grinding device. Background Art

[0002] Crushing and grinding graphite is a key process when graphite is processed into graphite powder. Large pieces of graphite are crushed into small pieces and ground into powder by equipment, and can be used to manufacture various graphite products subsequently. However, the existing crushing and grinding equipment has a simple structure, poor crushing and grinding effects, and graphite cannot be sufficiently crushed and ground, resulting in repeated processing, low processing efficiency, and often the crushing and grinding are carried out by different equipment, with poor processing continuity.

[0003] A Chinese invention patent with the publication number CN111992322B discloses a graphite crushing and grinding device, including a crushing box. A bracket is fixed at the bottom of the crushing box. A conveying cylinder is inserted through the inner bottom of the crushing box. A motor is fixed on the inner wall of the conveying cylinder. The upper output shaft of the motor is connected to a screw conveyor shaft through a one-way bearing. A driving rod is fixed at the top of the screw conveyor shaft. A plurality of stirring blades are fixed on the side wall of the driving rod. By driving the screw conveyor shaft to rotate by the motor, the stirring blades are driven to rotate under the driving of the driving rod, so that the raw materials inside the crushing box are continuously subjected to preliminary crushing under the collision of the stirring blades, and the preliminarily crushed raw materials will enter the inside of the conveying cylinder, and then be conveyed upward by the screw conveyor shaft and further crushed by extrusion during the conveying process, and the raw materials falling from the top of the conveying cylinder will be able to better collide with the stirring blades to complete the crushing process.

[0004] Although it enables graphite to be repeatedly cut and crushed in one device to a certain extent, its crushing structure is simple, the cutting effect is poor, repeated cutting is required, and the extrusion crushing effect during screw conveyor transportation is very limited, resulting in limited improvement in processing efficiency, and graphite still cannot be sufficiently crushed in a short time.

Specific embodiments

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] Embodiment 1

[0032] Such as Figures 1 to 6As shown in the figure, an efficient graphite crushing and grinding device includes a main crushing barrel 1. Inside the main crushing barrel 1, there is a bearing barrel 2. Inside the bearing barrel 2, there is a transmission mechanism 3. On the bearing barrel 2, there is a crushing mechanism 4. The transmission mechanism 3 includes a motor a 31 fixedly arranged at the bottom of the main crushing barrel 1 and an auger 32 driven by the motor a 31. The crushing mechanism 4 includes a cutting assembly 41 rotatably arranged outside the bearing barrel 2, a roll pressing assembly 42 driven by the cutting assembly 41, and an extrusion assembly 43 driven by the auger 32. The cutting assembly 41 cuts the raw materials inside the main crushing barrel 1. The auger 32 drives the cut raw materials into the bearing barrel 2. The roll pressing assembly 42 and the extrusion assembly 43 successively grind the raw materials entering the bearing barrel 2. By successively crushing and grinding the raw materials through the cutting assembly 41, the roll pressing assembly 42, and the extrusion assembly 43, the graphite raw materials are fully crushed and ground, with better processing efficiency and less processing time required, solving the problems in the prior art that the crushing mechanism is simple and the cutting effect is poor, and the graphite cannot be fully crushed in a short time, resulting in still low processing efficiency.

[0033] As Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, a conveying cylinder 21 is fixedly arranged inside the bearing barrel 2. A blanking channel a 22 and a blanking channel b 23 are formed between the conveying cylinder 21 and the bearing barrel 2. Windows a 24 and b 25 are respectively opened at the top and bottom of the conveying cylinder 21. A plurality of through holes 26 are arrayed in the height direction at the bottom of the conveying cylinder 21. The inner side of the window b 25 is set to be inclined. A filter screen 27 is fixedly arranged at the bottom of the blanking channel b 23. The upper part of the bearing barrel 2 is funnel-shaped, enabling the graphite raw materials entering the blanking channel a 22 to smoothly fall into the blanking channel b 23, avoiding blockage in the blanking channel a 22. The raw materials cut by the cutting assembly 41 enter the inside of the bearing barrel 2 through the window a 24 driven by the auger 32. The window b 25 is used to install a flap 433. A rotating hole is opened in the window b 25 corresponding to the rotating rod 434. The raw materials meeting the size after crushing and grinding pass through the filter screen 27 for output collection, while the raw materials not meeting the size remain on the upper surface of the filter screen 27. The inner side of the window b 25 is set to be inclined so that the raw materials not passing through the filter screen 27 can quickly fall into the auger 32 from the window b 25 after pushing the flap 433 to flip after accumulation, improving the processing efficiency.

[0034] As Figure 1 , Figure 2 and Figure 5As shown, a rotating groove a28 is fixedly arranged on the outer wall of the bearing barrel 2, and a feeding hopper 29 is fixedly connected to the top of the bearing barrel 2. By providing the rotating groove a28, a limiting and fixing effect is exerted on the rotating sleeve a413, enabling the rotating sleeve a413 to rotate smoothly driven by the motor b410. The graphite raw material to be processed is fed through the feeding hopper 29.

[0035] As Figure 3 shown, the cutting assembly 41 includes a motor b410 fixedly arranged at the top end of the bearing barrel 2 and a support rod 411 driven by the motor b410. Connecting rods a412 are fixedly connected to both ends of the support rod 411. The motor b410 drives the support rod 411 to rotate clockwise. While the support rod 411 rotates, it drives the cutting assembly 41 and the rolling assembly 42 connected by the connecting rod a412 and the connecting rod b420 to rotate synchronously. The linkage effect between the components is good, effectively saving the power energy cost.

[0036] As Figure 3 shown, the cutting assembly 41 further includes a rotating sleeve a413 rotatably arranged in the rotating groove a28. A cutting knife a414 and a cutting knife b415 are fixedly connected to the rotating sleeve a413. There are two cutting knives a414 and two cutting knives b415 respectively. The top of the cutting knife a414 is fixedly connected to the connecting rod a412. Rotating seats 416 are fixedly connected to the bottoms of the cutting knife a414 and the tops of the cutting knife b415. Rollers 417 are rotatably arranged on the rotating seats 416. The motor b410 drives the support rod 411 to rotate clockwise. While the support rod 411 rotates, it drives the cutting knife a414 and the cutting knife b415 to rotate synchronously to cut and break the graphite raw material entering the main body 1 of the crushing barrel. A cutting knife c4110 is installed between the cutting knife a414 and the cutting knife b415, and the blade direction is opposite to that of the cutting knife a414 and the cutting knife b415. During the process of the cutting knife a414 and the cutting knife b415 rotating clockwise driven by the motor b410 to cut the graphite raw material, the rollers 417 cooperate with the cutting knife c4110 to roll the cut graphite so that part of the graphite can be crushed, better improving the crushing effect of the graphite.

[0037] As Figure 2 and Figure 3As shown, a rotating groove b418 is fixedly arranged in the middle of the rotating sleeve a413. A rotating sleeve b419 is rotatably arranged in the rotating groove b418. A plurality of cutting knives c4110 are circumferentially arranged on the rotating sleeve b419. The cutting knives c4110 are installed between the cutting knife a414 and the cutting knife b415 and are arranged in the opposite direction to the cutting knife a414 and the cutting knife b415. During the rotation and cutting process of the cutting knife a414 and the cutting knife b415, the cutting knives c4110 are cooperated with through the rollers 417 to roll the cut graphite so that part of the graphite can be crushed, better improving the crushing effect of the graphite. A plurality of cutting knives c4110 are circumferentially arranged on the rotating sleeve b419, which can increase the rolling area. And the cutting knives c4110 are arranged in the rotating groove b418 by being grasped by the rotating sleeve b419. During the rotation process of the cutting knife a414 and the cutting knife b415, the cutting knives c4110 can be driven to rotate to a certain extent through the frictional force, and can also play a role in cutting and crushing the graphite raw material.

[0038] As Figure 3 , Figure 4 and Figure 5 shown, the roll pressing assembly 42 includes connecting rods b420 fixedly arranged at both ends of the support rod 411 and a fixing member 421 fixedly arranged on the outer wall of the conveying cylinder 21. A rotating shaft a422 is fixedly connected to the bottom of the connecting rod b420. A roller a423 is rotatably arranged on the rotating shaft a422. A rotating shaft b424 is fixedly connected to the fixing member 421. A roller b425 is rotatably arranged on the rotating shaft b424. The roller a423 is rotatably arranged on the rotating shaft a422 and rotates synchronously with the support rod 411. The graphite raw material cut by the cutting assembly 41 enters the auger 32 and enters the bearing barrel 2 under the drive of the auger 32. When the graphite raw material falls to the blanking channel a22, the roller a423 and the roller b423 rotatably arranged on the rotating shaft b424 cooperate to perform secondary roll pressing and grinding on the graphite raw material. The roller a423 can not only revolve with the support rod 411 but also rotate on its own, which can further crush the graphite more evenly.

[0039] As Figure 6As shown in the figure, the extrusion assembly 43 includes a sliding rod 430 slidably disposed in the through hole 26. The tail end of the sliding rod 430 is provided with an inclined surface. The front end of the sliding rod 430 is fixedly connected with an arc-shaped plate 431. A spring 432 is sleeved on the sliding rod 430, and the other end of the spring 432 is fixedly connected with the inner wall of the conveying cylinder 21. The sliding rod 430 is arranged on the rotation path of the auger 32. During the rotation and lifting process of the auger 32, the tail end of the sliding rod 430 can be pushed, so that the sliding rod 430 moves outward along the through hole 26 to further extrude and crush the graphite raw material entering the blanking channel b23 through the arc-shaped plate 431. The graphite raw material meeting the size passes through the lower filter screen 27. The unpassed raw materials are piled up to make the flap 433 flip and then fall into the auger 32 and are crushed and ground again through the rolling pressure assembly 42 and the extrusion assembly 43. The size of the arc-shaped plate 431 matches the inner diameter of the blanking channel b23 of the bearing barrel 2. The tail end of the sliding rod 430 is inclined, so that the auger 32 can push the sliding rod 430 during the rotation and lifting process without interference. When the auger 32 does not contact the tail end of the sliding rod 430, the sliding rod 430 is reset under the action of the spring 432, so that a plurality of arc-shaped plates 431 arranged in the height direction can alternately extrude the graphite raw material, and the crushing effect is more thorough.

[0040] As Figure 6 shown, the extrusion assembly 43 further includes a flap 433 rotatably disposed in the window b25. Both sides of the flap 433 are fixedly connected with rotating rods 434, and torsion springs 435 are fixedly connected to the rotating rods 434. During the rotation and lifting process of the auger 32, the tail end of the sliding rod 430 can be pushed, so that the sliding rod 430 moves outward to further extrude and crush the graphite raw material entering the blanking channel b23 through the arc-shaped plate 431. The graphite raw material meeting the size passes through the lower filter screen 27. The filter screen 27 is inclined. The unpassed raw materials are piled up to a certain amount and then the flap 433 is flipped towards the conveying cylinder 21 by gravity and then falls into the auger 32 and is crushed and ground again through the rolling pressure assembly 42 and the extrusion assembly 43. When the larger-sized graphite raw materials are piled up and enter the auger 32, the flap 433 is reset under the action of the torsion spring 435 to close the window b25, preventing the graphite raw material meeting the size from entering the conveying cylinder 21 and causing loss.

[0041] As Figure 2 shown, a guide groove 11 is fixedly connected to the bottom of the main body 1 of the crushing barrel corresponding to the blanking channel b23. The guide groove 11 is communicated with the blanking channel b23. Through the guide groove 11, the graphite powder passing through the filter screen 27 can be collected more concentratedly, avoiding the leakage of graphite powder and polluting the external environment.

[0042] Embodiment 2

[0043] As Figure 5As shown in the figure, the same or corresponding components as those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below; the difference between the second embodiment and the first embodiment is that a groove 210 is provided on the inner wall of the top end of the bearing barrel 2. By providing the groove 210, the support rod 411 can rotate in the groove 210, and at the same time, the top of the bearing barrel 2 is flush with the outer edge of the groove 210, so as to prevent the raw materials in the crushing barrel main body 1 from falling into the bearing barrel 2 and affecting the processing.

[0044] Working process

[0045] First, load the graphite raw materials to be processed into the feeding hopper 29, and then start the motor a31 and the motor b410. The motor b410 drives the support rod 411 to rotate clockwise. While the support rod 411 rotates, it drives the cutter a414 and the cutter b415 to rotate synchronously to cut and crush the graphite raw materials entering the crushing barrel main body 1. During the process that the cutter a414 and the cutter b415 rotate clockwise driven by the motor b410 to cut the graphite raw materials, they cooperate with the cutter c4110 through the roller 417 to roll and crush the cut graphite so that part of the graphite can be crushed. After the graphite raw materials cut by the cutting assembly 41 fall, they enter the auger 32 and are driven by the auger 32 into the bearing barrel 2. When the graphite raw materials fall to the blanking channel a22, the roller a423 rotates synchronously with the motor b410 and cooperates with the roller b423 rotatably arranged on the rotating shaft b424 to perform secondary roller pressing and grinding on the graphite raw materials. The roller-pressed raw materials fall into the blanking channel b23. During the process of rotation and lifting by the auger 32, the tail end of the sliding rod 430 is pushed, so that the sliding rod 430 moves outward along the through hole 26 and squeezes and crushes the graphite raw materials entering the blanking channel b23 again through the arc-shaped plate 431. The graphite raw materials that meet the size requirements after extrusion pass through the filter screen 27 below and are output through the guide groove 11. The raw materials that do not pass through accumulate to a certain amount and then, due to gravity, cause the flap 433 to turn towards the conveying cylinder 21 and thus fall into the auger 32, and are again crushed and ground by the roller pressing assembly 42 and the extrusion assembly 43. When the larger-sized graphite raw materials that have accumulated enter the auger 32, the flap 433 resets under the action of the torsion spring 435, and the processing process circulates in turn.
