Description

Technical Field

[0001] This utility model relates to the field of crushing and screening equipment technology, and in particular to an integrated crushing and screening equipment for graphite raw materials. Background Technology

[0002] Graphite is an important industrial material widely used in batteries, lubricants, and refractory materials. Crushing and screening are two key processes in graphite processing, directly impacting the quality of the final product and production efficiency. Traditional graphite processing equipment typically uses separate crushers and screening machines. This separate design results in large footprints, high energy consumption, and dust pollution during material transfer, negatively affecting the working environment.

[0003] In practical use, the existing equipment still has the following shortcomings:

[0004] First, the graphite particles after crushing are of uneven size, resulting in an unsatisfactory screening effect, which causes some substandard particles to be mixed into the finished product.

[0005] Secondly, the equipment has a complex structure, making disassembly and cleaning difficult. In particular, the screen part is prone to material accumulation, which affects the long-term stability of use.

[0006] Third, the lack of integrated design means that materials need to be transferred multiple times during crushing and screening, which increases energy consumption and production time. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an integrated crushing and screening equipment for graphite raw materials, which overcomes the deficiencies of existing technologies and effectively solves the problems of unsatisfactory screening effect, difficulty in disassembling and cleaning screens, and the need for multiple transfers of materials during the crushing and screening process.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An integrated graphite raw material crushing and screening device includes a fixed box. A box cover is hinged to one side of the top of the fixed box, and a feed pipe is inserted into the top of the box cover. Crushing mechanisms are installed and fixed on the inner walls of both sides of the fixed box. The crushing mechanism includes a crushing component and a filtering component. The crushing component includes intermeshing crushing rollers, a first disc rotatably connected to one end of the two crushing rollers, a second disc rotatably connected to the other end of the two crushing rollers, a rotating ring rotatably connected to the outer wall of the first disc, a guide pipe inserted into the top of the outer wall of one side of the first disc, a ring rotatably connected to the outer wall of the second disc, positioning blocks welded and fixed to the outer wall of the ring at equal intervals along the ring, and rotating shafts connected to one end of the two crushing rollers respectively through couplings. The filtering component includes a first connecting ring, baffles welded and fixed to the outer wall of one side of the first connecting ring at equal intervals along the ring, screens welded and fixed between two adjacent baffles, a second connecting ring welded and fixed to one end of the baffle, and a screw welded and fixed to the outer wall of one side of the second connecting ring along the ring.

[0010] Graphite raw material enters the feed pipe from the feed pipe and falls between two crushing rollers. The servo motor drives the crushing rollers to rotate in opposite directions through the rotating shaft, crushing the raw material. The crushed material falls into the filter assembly, where the screen vibrates under the drive of the ring. Qualified particles pass through the screen holes and enter the discharge hopper, while larger particles are intercepted by the baffle and re-enter the crushing zone. Throughout the process, the gear transmission system ensures that crushing and screening are carried out synchronously, while the modular design facilitates maintenance and cleaning, ultimately achieving efficient and energy-saving integrated processing.

[0011] Preferably, a handle is welded to the top of the fixed box, and the bottom of the feed pipe and the top of the guide pipe are connected to each other.

[0012] Preferably, a discharge hopper is inserted and fixed to the bottom of the fixed box, and a servo motor is installed and fixed on one side of the outer wall of the fixed box. The servo motor is connected and fixed to one end of one of the rotating shafts through a coupling.

[0013] Preferably, mounting brackets are welded and fixed to the bottom of the outer walls on the opposite sides of the first and second discs, and the two mounting brackets are respectively installed and fixed to the inner walls on both sides of the fixed box by bolts.

[0014] Preferably, an opening is provided on the top of one side of the outer wall of the first disc to form an insertion fit with the guide tube, and connecting blocks are welded and fixed on both sides of the opening and the bottom sides of the guide tube. A plug is inserted into the top of the connecting block, and the opening and the guide tube are fastened together by the connecting block and the plug.

[0015] Preferably, both of the rotating shafts have large gears that mesh with each other fitted onto their rod walls, and a protruding rod is rotatably connected to one side of the outer wall of the second disc. A small gear that meshes with the large gear is fitted onto the rod wall of the protruding rod. Equally spaced protruding teeth are welded to the inner wall of the ring, and the protruding teeth mesh with the small gear.

[0016] Preferably, the inner diameters of the first connecting ring and the second connecting ring are both adapted to the outer diameters of the first disk and the second disk, and the positioning block and the screw form an insertion fit, and the second connecting ring and the second disk form a fastening fit through the positioning block, the screw and the nut.

[0017] The beneficial effects of this utility model are as follows:

[0018] High-efficiency integrated crushing and screening: This invention integrates the crushing mechanism and the filter assembly within a fixed housing, achieving integrated crushing and screening of graphite raw materials. The crushing assembly uses intermeshing crushing rollers to uniformly crush the raw material, while the filter assembly, through the cooperation of a screen and baffles, screens qualified particles in real time, avoiding efficiency losses and dust pollution caused by material transfer in traditional equipment. Furthermore, the direct connection design between the guide pipe and the feed pipe further simplifies the material flow path and improves production efficiency.

[0019] Optimized Structure and Convenient Maintenance: This utility model utilizes a modular design, making the crushing and screening components easy to disassemble and clean. For example, the screen is fixed by a first connecting ring and a second connecting ring, and quick installation is achieved using screws and positioning blocks, solving the problems of easy clogging and difficult replacement of traditional screens. Simultaneously, a servo motor drives the rotating shaft and a large gear transmission system, ensuring stable operation of the crushing rollers and reducing energy consumption and wear. The meshing design of the convex teeth on the ring and the small gear further improves the dynamic stability of the screening components and extends the service life of the equipment.

[0028] A handle 3 is welded to the top of the fixed box 1. The bottom of the feed pipe 4 is inserted into and connected to the top of the guide pipe 17. A discharge hopper 5 is inserted into and fixed to the bottom of the fixed box 1. A servo motor 6 is installed and fixed on one side of the outer wall of the fixed box 1. The servo motor 6 is connected to one end of one of the rotating shafts 20 through a coupling. Mounting brackets 14 are welded to the bottom of the outer walls of the first disc 11 and the second disc 12 that are far apart from each other. The two mounting brackets 14 are respectively installed and fixed to the inner walls of the two sides of the fixed box 1 by bolts. An opening is opened on the top of one side of the outer wall of the first disc 11 to form an insertion fit with the guide pipe 17. Connecting blocks 15 are welded to both sides of the opening and the bottom ends of the guide pipe 17. A plug rod 16 is inserted into the top of the connecting block 15. The opening and the guide pipe 17 are securely connected by a connecting block 15 and a plug rod 16. The fixed box 1 serves as the main frame, with a hinged box cover 2 at the top for easy internal maintenance. The feed pipe 4 is connected to the guide pipe 17 to ensure that the graphite raw material enters the crushing area directly. The crushing mechanism 7 includes a crushing component 8 and a filtering component 9. The crushing roller 10 is supported by a first disc 11 and a second disc 12, and is connected to a servo motor 6 via a rotating shaft 20 for power transmission. The two crushing rollers 10 mesh with each other to fully crush the raw material. The first disc 11 and the second disc 12 are fixed in the fixed box 1 by a mounting bracket 14 to ensure stability. The guide pipe 17 is securely connected to the first disc 11 by the connecting block 15 and the plug rod 16 to prevent material leakage.

The second connecting ring 24 is fixed to the positioning block 19 by the screw 25, which facilitates quick disassembly and cleaning. The servo motor 6 drives the rotating shaft 20, which transmits power to the crushing roller 10 through the meshing of the large gear. The engagement of the small gear and the convex tooth further drives the ring 18 to rotate, so that the uncrushed raw materials continuously enter the crushing roller for crushing, improving the crushing and screening efficiency and avoiding blockage. The qualified particles after crushing fall into the discharge hopper 5 through the screen 23, while the unqualified particles continue to remain in the crushing area for secondary processing to ensure the quality of the finished product.

[0030] Working principle:

[0031] During operation, graphite raw material enters the feed pipe 17 from the feed pipe 4 and falls between the two crushing rollers 10. The servo motor 6 drives the crushing rollers 10 to rotate in opposite directions via the rotating shaft 20, crushing the raw material. The crushed material falls into the filter assembly 9, where the screen 23 vibrates under the influence of the ring 18. Qualified particles pass through the screen holes and enter the discharge hopper 5, while larger particles are intercepted by the baffle 22 and re-enter the crushing zone. Throughout the process, the gear transmission system ensures synchronous crushing and screening, while the modular design facilitates maintenance and cleaning, ultimately achieving efficient and energy-saving integrated processing.
