Description

Technical Field

[0001] This utility model relates to the field of crushing technology, and in particular to a crushing mechanism. Background Technology

[0002] A crushing mechanism is a mechanical device or component used to crush large materials into smaller pieces or powder. It is widely used in industries, agriculture, mining and other fields to improve material processing efficiency and the feasibility of subsequent processing.

[0003] Currently, in the process of preparing silicon-carbon anodes, crushing mechanisms are required to crush the raw materials of silicon-carbon anodes.

[0004] Silicon-carbon anode materials are typically composed of nano-silicon particles and a carbon matrix, exhibiting high hardness and significant wear resistance. Current crushing processes commonly employ mechanical crushing equipment, such as hammer crushers, jaw crushers, or ball mills. The core crushing components (including hammers and liners) and particle size control elements (such as screens) of these machines are often made of wear-resistant alloy steels such as high-manganese steel and high-chromium cast iron. During the high-speed impact, compression, and friction crushing process, these metal components undergo wear due to continuous and intense mechanical forces, producing micron-sized and even nano-sized metal wear particles (primarily Fe). These metallic impurities inevitably contaminate the final product, adversely affecting the material's purity and application performance.

[0005] Therefore, we propose a crushing mechanism. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a crushing mechanism.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a crushing mechanism, including a hammer crusher body, a support frame fixedly connected to the bottom of the hammer crusher body, and a discharge pipe fixedly connected to the discharge end of the hammer crusher body.

[0008] The two outer walls of the discharge pipe are fixedly connected with arc-shaped shells on both sides, one above the other. The interior of each arc-shaped shell is provided with a support cylinder. Multiple strip electromagnets are fixedly embedded on the outer surface of each support cylinder. The outer surfaces of the multiple strip electromagnets on the same support cylinder are fixedly fitted with a sleeve, and the sleeve is fixedly connected to the support cylinder.

[0009] Both sleeves have scraper strips abutting their bottoms, and the scraper strips are fixedly connected to the arc-shaped outer shell;

[0010] The mounting shafts at both ends of the two support cylinders are both provided to pass through the adjacent arc-shaped outer shell and are rotatably and sealed to the adjacent arc-shaped outer shell;

[0011] Both support cylinders are equipped with a synchronous transmission assembly.

[0012] The synchronous transmission assembly and the hammer crusher body are both equipped with a belt transmission assembly.

[0013] Furthermore, both of the arc-shaped outer shells have discharge pipes at their bottoms, allowing the scraped ferromagnetic impurities to be collected and discharged smoothly.

[0014] Furthermore, the discharge pipe and the two arc-shaped outer shells are fixedly connected to the support frame, which enhances the overall rigidity and stability of the entire discharge and iron removal system.

[0015] Furthermore, bearing seats are fixedly connected to both ends of the two arc-shaped outer shells, and the inner ring of the bearing built into the bearing seat is fixedly sleeved on the outer surface of the support cylinder mounting shaft. The bearing seats provide stable support for the support cylinder, ensuring the smoothness and concentricity of the support cylinder during high-speed rotation.

[0016] Furthermore, the synchronous transmission assembly includes two synchronous pulleys, one of which is fixedly connected to the mounting shaft of the adjacent support cylinder, and the other synchronous pulley is rotatably connected to the adjacent arc-shaped outer shell. The outer surfaces of the two synchronous pulleys are meshed with a synchronous belt, and the use of synchronous belt transmission ensures that the two support cylinders can accurately maintain opposite synchronous rotation.

[0017] Furthermore, the synchronous transmission assembly also includes two meshing gears, one of which is fixedly connected to the mounting shaft of the adjacent support cylinder, and the other gear is fixedly connected to the adjacent synchronous pulley. The gear meshing transmission accurately transmits power from one support cylinder to the other.

[0018] Furthermore, the belt drive assembly includes a small V-belt pulley, which is fixed to the main shaft of the hammer crusher body. A V-belt body is sleeved on the outer surface of the small V-belt pulley, and a large V-belt pulley is abutted on the inner surface of the V-belt body. One end of the large V-belt pulley is fixedly connected to a connecting shaft, which is fixedly connected to an adjacent gear. This design directly utilizes the crusher main shaft as a power source, eliminating the need for an additional drive device and achieving energy-saving control of the iron removal system and the crushing host.

[0019] The beneficial effects of this utility model are:

[0020] In use, this invention utilizes a rotating support cylinder and sleeve structure with built-in bar electromagnets on both sides of the discharge pipe, along with a scraper and synchronous transmission system, to automatically and continuously adsorb and remove ferromagnetic metal wear particles from the material during the crushing and discharge process. This effectively reduces the metal impurity content in the final product and improves the purity and application performance of the silicon-carbon anode material. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-4 As shown, a crushing mechanism is disclosed, including a hammer crusher body 1, which serves as the core crushing component. The body contains conventional structures such as a rotor, hammers, liners, a feed inlet, and a drive unit. During operation, a motor drives the main shaft to rotate at high speed, causing the hammers to impact, shear, and grind materials such as silicon-carbon anodes entering from the feed inlet, crushing them to the required particle size.

[0030] A support frame 6 is fixedly connected to the bottom of the hammer crusher body 1. The support frame 6 is welded from shaped steel. A discharge pipe 10 is fixedly connected to the discharge end of the hammer crusher body 1. Arc-shaped shells 5 are fixedly connected to the outer walls on both sides of the discharge pipe 10. A discharge pipe 13 is opened at the bottom of each of the two arc-shaped shells 5. The discharge pipe 10 and the two arc-shaped shells 5 are fixedly connected to the support frame 6. The shape of the arc-shaped shells 5 is adapted to the internal rotating sleeve 15 to form a semi-enclosed space.

[0031] Both arc-shaped outer shells 5 are equipped with support cylinders 11 inside. Multiple strip electromagnets 14 are fixedly embedded on the outer surface of both support cylinders 11. A sleeve 15 is fixedly sleeved on the outer surface of the multiple strip electromagnets 14 on the same support cylinder 11, and the sleeve 15 is fixedly connected to the support cylinder 11.

[0032] The bottom of both sleeves 15 abuts against scraper strips 12, and the scraper strips 12 are fixedly connected to the arc-shaped outer shell 5. The scraper strips 12 are strip-shaped components made of wear-resistant materials (such as polyurethane, hard alloy or wear-resistant steel).

[0033] The two end mounting shafts of the two support cylinders 11 are both set through the adjacent arc-shaped outer shells 5 and are sealed and rotatably connected to the adjacent arc-shaped outer shells 5. The two ends of the two arc-shaped outer shells 5 are fixedly connected to the bearing seats 7, and the inner ring of the bearing built into the bearing seat 7 is fixedly sleeved on the outer surface of the mounting shaft of the support cylinder 11. The mounting shaft and the arc-shaped outer shell 5 are sealed by a sealing ring.

[0034] Two support cylinders 11 are jointly equipped with a synchronous transmission assembly, which includes two synchronous pulleys 9. One of the synchronous pulleys 9 is fixedly connected to the mounting shaft of the adjacent support cylinder 11, and the other synchronous pulley 9 is rotatably connected to the adjacent arc-shaped housing 5. The outer surfaces of the two synchronous pulleys 9 are meshed with a synchronous belt 8. The synchronous transmission assembly also includes two meshing gears 16. One gear 16 is fixedly connected to the mounting shaft of the adjacent support cylinder 11, and the other gear 16 is fixedly connected to the adjacent synchronous pulley 9. The synchronous belt 8 is a ring belt with teeth on its working surface, which meshes with the tooth grooves of the synchronous pulleys 9 to transmit power and motion between the two synchronous pulleys 9. Due to its meshing transmission characteristics, slippage can be avoided, ensuring the synchronous accuracy of the transmission.

[0035] The synchronous transmission assembly and the hammer crusher body 1 are jointly equipped with a belt transmission assembly. The belt transmission assembly includes a small V-belt pulley 2, which is fixed to the main shaft of the hammer crusher body 1. A V-belt body 3 is sleeved on the outer surface of the small V-belt pulley 2, and a large V-belt pulley 4 is abutted on the inner surface of the V-belt body 3. A connecting shaft 17 is fixedly connected to one end of the large V-belt pulley 4, and the connecting shaft 17 is fixedly connected to the adjacent gear 16. The V-belt body 3 is a common multi-wedge belt, which is sleeved between the small V-belt pulley 2 and the large V-belt pulley 4. Power is transmitted from the high-speed crusher main shaft to the low-speed large V-belt pulley 4 through friction transmission.

[0036] Working principle: When the hammer crusher body 1 is running and performing crushing operations, its main shaft rotates, which allows the small V-belt pulley 2 fixed on its main shaft to transmit power to the large V-belt pulley 4 through the V-belt body 3. The large V-belt pulley 4 drives the gear 16 fixed to it to rotate through the connecting shaft 17. The gear 16 drives the support cylinder 11 connected to it to rotate clockwise. At the same time, the gear 16 drives the adjacent synchronous pulley 9 to rotate through another gear 16. The two synchronous pulleys 9 rotate synchronously under the action of the synchronous belt 8, thus driving the other support cylinder 11 to rotate counterclockwise.

[0037] The material crushed by the hammer crusher body 1 is discharged from the discharge pipe 10. During this period, it passes through the gap formed by the two support cylinders 11 and the discharge pipe 10, and some material will also fall on the local area of ​​the surface of the two sleeves 15.

[0038] As the two support cylinders 11 rotate synchronously in opposite directions under the drive of the transmission assembly, the bar electromagnet 14 fixedly embedded on the outer surface of the support cylinder 11 generates a strong magnetic field after being energized.

[0039] When the mixture passes through the inside of the discharge pipe 10 and sweeps across the surface of the rotating sleeve 15, the ferromagnetic metal wear impurities (such as Fe particles) contained in the material will be firmly attracted to the outer surface of the sleeve 15 by the magnetic field generated by the bar electromagnet 14.

[0040] The non-magnetic materials that are not adsorbed continue to fall under gravity and are eventually discharged through the bottom of the discharge pipe 10, completing the collection. This process achieves dynamic separation of ferrous impurities from the desired materials.

[0041] The area of ​​sleeve 15 with adsorbed iron impurities moves continuously as the support cylinder 11 rotates. When the surface of sleeve 15 with adsorbed impurities rotates to the bottom and comes into contact with the scraper 12, the hard scraper 12 will scrape off the iron impurities attached to the surface of sleeve 15. The scraped iron impurities fall into the bottom of the arc-shaped outer shell 5 and are eventually discharged separately through the discharge pipe 13 at the bottom.

[0042] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
