[0001] This utility model relates to the field of iron powder crushing technology, and in particular to an iron powder crusher. Background Technology

[0002] Iron powder is an important industrial raw material in metallurgy, machining, powder metallurgy raw material preparation and related circular economy industries. Its particle size control is directly related to the performance and quality of the products.

[0003] However, existing iron powder crushing equipment (such as hammer crushers) mainly achieves material crushing through impact or compression, resulting in fewer crushing cycles and difficulty in ensuring the fineness of iron powder particle size. Additionally, some users utilize ball mills. However, existing ball mills typically involve feeding material into a rotating drum, where the material is crushed by the rotating drum and internal grinding balls before being discharged through a screw conveyor. Because some large pieces of material do not effectively contact the grinding balls during their displacement within the drum, the resulting particles are of varying sizes, often resulting in uncrushed material. Therefore, even using a ball mill cannot guarantee the precision of particle size distribution. Utility Model Content

[0004] The purpose of this invention is to provide an iron powder crusher that can crush iron powder materials multiple times to ensure the fineness of the iron powder particle size.

[0005] To achieve the above objectives, this utility model provides the following solution:

Detailed Implementation

[0021] This utility model provides an iron powder crusher, such as Figures 1-3 As shown, the device includes a grinding cylinder 1, with a gear ring 2 sleeved and fixedly connected to the center of the grinding cylinder 1. The gear ring 2 meshes with a gear 3. Specifically, the outer wall of the gear ring 2 has a first tooth 4, and the outer wall of the gear 3 has a second tooth 5. The first tooth 4 and the second tooth 5 mesh, realizing the transmission between the gear ring 2 and the gear 3. The gear 3 is connected to a first motor 6. Specifically, the gear 3 is fixedly connected to the output shaft of the first motor 6. Therefore, when the first motor 6 starts, the rotation of the output shaft of the first motor 6 will drive the rotation of the gear 3, which in turn drives the rotation of the gear ring 2, and thus drives the rotation of the grinding cylinder 1. A crushing shaft 7 is axially arranged inside the grinding cylinder 1, located at the center of the grinding cylinder 1. Several crushing blades 8 are evenly distributed on the crushing shaft 7. The crushing shaft 7 is connected to a second motor 9. Specifically, the crushing shaft 7 is fixed to the output shaft of the second motor 9. Therefore, when the second motor 9 starts, the rotation of the output shaft of the second motor 9 will drive the crushing shaft 7 to rotate inside the grinding cylinder 1, thereby driving the crushing blades 8 to rotate around the crushing shaft 7 inside the grinding cylinder 1. The rotation of the crushing blades 8 will repeatedly crush the iron powder material inside the grinding cylinder 1. Several flaps 10 are evenly distributed circumferentially on the inner wall of the grinding cylinder 1. In this embodiment, there are 8 flaps 10, and each flap 10 is located in the direction of the inner diameter of the grinding cylinder 1. A gap is left between the flaps 10 and the crushing blades 8, making it easier for the iron powder material crushed by the crushing blades 8 to fall onto the flaps 10. After being cut by the crushing blades 8, the iron powder material inside the grinding cylinder 1 falls onto the inner wall at the bottom of the grinding cylinder 1. Due to the setting of the flap 10 on the inner wall of the grinding cylinder 1, the flap 10 will flip the iron powder up again as it rotates with the grinding cylinder 1 for repeated cutting and crushing. Due to the rotation of the grinding cylinder 1 and the rotation of the crushing blades 8, the iron powder material inside the grinding cylinder 1 is repeatedly cut. Compared with using a ball mill or hammer crusher to crush iron powder material, the crushing effect is better and the fineness of the iron powder particle size is guaranteed.

[0022] The grinding cylinder 1 has a feed inlet 11 at one end near the second motor 9 and a discharge outlet 12 at the other end. Iron powder enters the grinding cylinder 1 through the feed inlet 11 and leaves the grinding cylinder 1 through the discharge outlet 12. When crushing iron powder, the horizontal height of the feed inlet 11 is higher than that of the discharge outlet 12 so that the iron powder can move to the discharge outlet 12 by gravity after being crushed, so as to carry out the next process.

[0023] A first sleeve 13 is fitted onto one end of the grinding cylinder 1, and the first sleeve 13 is supported by a first support plate 14. A second sleeve 15 is fitted onto the other end of the grinding cylinder 1, and the second sleeve 15 is supported by a second support plate 16. The first support plate 14 and the second support plate 16 are fixedly connected to the base plate 17, ensuring the stability of the device. When the grinding cylinder 1 rotates, it can rotate within the first sleeve 13 and the second sleeve 15, which also serve as guides for the rotation of the grinding cylinder 1. One end of the crushing shaft 7 is rotatably connected to the first bracket 18 via a bearing, and the other end is rotatably connected to the second bracket 19 via a bearing. The first bracket 18 and the second bracket 19 are fixedly connected to the base plate 17, enabling the rotation of the crushing shaft 7.

[0024] A first support ring 20 and a second support ring 21, symmetrically arranged, are fitted and fixed to the grinding cylinder 1. The first support ring 20 is located between the first sleeve 13 and the gear ring 2, and the second support ring 21 is located between the second sleeve 15 and the gear ring 2. The first support ring 20 abuts against the first support roller 22, and the second support ring 21 abuts against the second support roller 23. The first support roller 22 and the second support roller 23 are fixed to the base plate 17. When the grinding cylinder 1 rotates, it will drive the first support ring 20 and the second support ring 21 to rotate. The first support roller 22 and the second support roller 23 will abut against the first support ring 20 and the second support ring 21 respectively. The first support roller 22 and the second support roller 23 support both sides of the grinding cylinder 1 and maintain the balance of the grinding cylinder 1.

[0025] The crushing blade 8 includes several blade arrays 24, each blade array 24 being uniformly fixed to the circumferential sidewall of the crushing shaft 7. The number of blade arrays 24 can be 4, 6, 8, or 10. In this embodiment, the number of blade arrays 24 is 4, which ensures both crushing effect and cost savings.

[0026] The iron powder crusher provided by this utility model, in specific application, transmits the iron powder material to be crushed to the grinding cylinder 1 through the feed inlet 11. The second motor 9 is started to rotate the crushing shaft 7, which in turn drives the crushing blades 8 to rotate. The crushing blades 8 crush the iron powder material. The first motor 6 is then started, which drives the gear 3 to rotate, which in turn drives the gear ring 2 to rotate, which in turn drives the grinding cylinder 1 to rotate. The iron powder material in the grinding cylinder 1, after being cut by the crushing blades 8, falls onto the flapper 10 on the inner wall at the bottom of the grinding cylinder 1. As the grinding cylinder 1 rotates, the flapper 10 flips the iron powder back up for repeated cutting and crushing. This repeated cutting of the iron powder material in the grinding cylinder 1 results in better crushing effect and ensures the fineness of the iron powder particle size. Then, under continuous cutting, the crushed material moves to the discharge port 12 of the grinding cylinder 1 for the next process.

[0027] It should be noted that this iron powder crusher is not limited to crushing iron powder materials, but can also crush other micro powder materials that need to be crushed.

[0028] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
