Traditional fixed screens are prone to problems such as screen clogging and material accumulation, especially when processing easily agglomerated materials like manganese oxide. Qualified particles cannot pass through the screen quickly, resulting in low screening efficiency and insufficient screening, which affects the finished product particle size qualification rate. Therefore, this invention proposes a novel solution. Utility Model Content

[0031] Please see Figure 1-7 This utility model provides a technical solution: an integrated manganese oxide abrasive screening device, including a screening box 1 and a screening component. The screening component is disposed inside the screening box 1 and includes a second fixing frame 24, which is fixedly connected inside the screening box 1. A third drive motor 19 is fixedly connected to the lower end of the second fixing frame 24. A screening plate 20 is fixedly connected to the output end of the third drive motor 19. A plurality of arc-shaped manganese oxide guide strips 21 are fixedly connected to the upper surface of the screening plate 20. A screening plate limiting plate 22 is fixedly connected to the inner wall of the screening box 1. The screening plate 20 and the screening plate limiting plate 22 are rotatably connected. A manganese oxide guide frame 2 is fixedly connected to the outer side of the screening box 1. A manganese oxide guide plate 11 is fixedly connected to the inside of the screening box 1. The manganese oxide guide frame 2, the manganese oxide guide plate 11, the third drive motor 19, the screening plate 20, the manganese oxide guide strips 21, the screening plate limiting plate 22, and the second fixing frame 24 are all inclinedly arranged on the screening box 1.

[0032] The screening assembly also includes a manganese oxide conveying cylinder 3, which is fixedly connected to the manganese oxide guide frame 2. A connecting cylinder 4 is fixedly connected to the upper side surface of the manganese oxide conveying cylinder 3. The end of the connecting cylinder 4 away from the manganese oxide conveying cylinder 3 is fixedly connected to the screening box 1. A first drive motor 7 is fixedly connected to the lower end of the manganese oxide conveying cylinder 3. A first rotating shaft 8 is fixedly connected to the output end of the first drive motor 7. The first rotating shaft 8 is rotatably connected to the manganese oxide conveying cylinder 3. Manganese oxide conveying blades 9 are fixedly connected to the surface of the first rotating shaft 8.

[0033] A baffle 10 is provided at the right end of the manganese oxide guide frame 2, and the baffle 10 is fixed to the manganese oxide guide frame 2 by bolts.

[0034] A second drive motor 13 is fixedly connected to the upper end of the screening box 1. A first fixed frame 15 is fixedly connected inside the screening box 1. A grinding roller connecting shaft 14 is fixedly connected to the output end of the second drive motor 13. The upper and lower ends of the grinding roller connecting shaft 14 are rotatably connected to the screening box 1 and the first fixed frame 15, respectively. A grinding roller 16 is fixedly connected to the surface of the grinding roller connecting shaft 14. The side of the grinding roller 16 is arc-shaped. A grinding cylinder 12 is fixedly connected to the inner wall of the screening box 1. The inner side of the grinding cylinder 12 is arc-shaped. The arc-shaped surfaces of the grinding roller 16 and the grinding cylinder 12 are compatible.

[0035] Multiple first grinding strips 17 are fixedly connected to the inner arc-shaped part of the grinding cylinder 12, and multiple second grinding strips 18 are fixedly connected to the side arc-shaped part of the grinding roller 16.

[0036] The grinding roller 16 is hollow, and multiple staggered support rods 23 are fixedly connected inside the grinding roller 16.

[0037] The upper end of the screening box 1 is fixedly connected to the manganese oxide feed pipe 5, and the lower end of the screening box 1 is fixedly connected to the manganese oxide discharge pipe 6.

[0038] When using this device, before screening manganese oxide, the manganese oxide is ground by a ball mill. A certain amount of steel balls are added to the ball mill and the grinding is carried out for 1-3 hours. Then, the ground manganese oxide raw material enters the device through the manganese oxide feed pipe 5 fixedly connected to the upper end of the screening box 1. The raw material first enters the grinding area formed by the grinding cylinder 12 and the grinding roller 16 to prepare for the subsequent grinding process.

[0039] After the second drive motor 13 starts, it drives the grinding roller connecting shaft 14 to rotate, thereby causing the grinding roller 16 fixed on the shaft to rotate relative to the grinding cylinder 12. Since the upper end of the grinding roller 16 is conical and the side is arc-shaped, and it is compatible with the inner arc-shaped grinding cylinder 12, and the first grinding strip 17 and the second grinding strip 18 are fixedly connected to the arc-shaped surfaces of the two respectively, during the rotation of the grinding roller 16, these grinding strips cooperate with each other to squeeze, shear and grind the manganese oxide raw material that enters the grinding cylinder 12. The grinding roller 16 is hollow and has staggered support rods 23 inside, which reduces weight while ensuring structural strength, and ensures that the grinding process is stable and efficient until the manganese oxide is ground to a certain particle size.

[0040] The ground manganese oxide material falls from the grinding cylinder 12 onto the inclined screening plate 20 inside the screening box 1. The third drive motor 19 drives the screening plate 20 to rotate, and at the same time, multiple arc-shaped manganese oxide guide strips 21 fixed to the upper surface of the screening plate 20 rotate accordingly. On the one hand, the inclined screening plate 20 and the screening plate limiting plate 22 rotate in coordination. During the rotation, the screening plate 20 screens the material. Fine manganese oxide particles that meet the particle size requirements pass through the screen holes of the screening plate 20 and are discharged directly from the manganese oxide discharge pipe 6 fixedly connected to the lower end of the screening box 1, becoming qualified finished products. On the other hand, the rotation of the manganese oxide guide strips 21 can drive the manganese oxide material on the surface of the screening plate 20 to converge towards the center of the screening plate 20, avoiding material accumulation at the edges, ensuring that the screening process is thorough and uniform, and effectively improving the screening efficiency.

[0041] Larger manganese oxide particles that fail to pass through the sieve holes of the sieve plate 20 slide down from the lower end of the sieve plate 20 due to the tilt angle and rotation of the sieve plate 20. The sliding material is guided by the manganese oxide guide plate 11 inclined inside the sieve box 1 and enters the manganese oxide guide frame 2 fixedly connected to the outside of the sieve box 1. The baffle 10 at the right end of the manganese oxide guide frame 2 can prevent the material from overflowing and ensure smooth material conveying. Subsequently, the material enters the manganese oxide conveying cylinder 3 fixed on the manganese oxide guide frame 2.

[0042] In the manganese oxide conveying cylinder 3, the first drive motor 7 drives the first rotating shaft 8 to rotate, and the manganese oxide conveying blades 9 fixed on the surface of the first rotating shaft 8 rotate accordingly, conveying the manganese oxide material back to the screening box 1 along the manganese oxide conveying cylinder 3 and the connecting cylinder 4, returning to the grinding cylinder 12 and the grinding roller 16 for a new round of grinding and screening; this cycle continues until all the manganese oxide material reaches the required particle size, realizing continuous and automated grinding and screening of manganese oxide abrasive.

[0043] Finally, after the device completes the screening operation, the baffle 10 on the right end of the manganese oxide guide frame 2 can be removed; the manganese oxide material remaining inside the manganese oxide guide frame 2 and the manganese oxide conveying cylinder 3 is no longer obstructed and can be easily removed manually, which facilitates the cleaning and maintenance of the device and avoids the residual material affecting the efficiency and quality of the next production operation.

[0044] Furthermore, the screening plate 20 of this device is inclined and rotatably connected to the screening plate limiting plate 22, and is equipped with a manganese oxide guide strip 21 with an arc-shaped surface. During the screening process, the third drive motor 19 drives the screening plate 20 to rotate, which not only effectively prevents the screen holes from clogging, but also allows the material to pass through the screen quickly through the centrifugal force and the inclined surface. The manganese oxide guide strip 21 gathers the material towards the center of the screening plate 20, ensuring that all materials can fully participate in the screening and effectively avoiding the accumulation of materials inside the screening box 1. This improves the screening efficiency and the finished product particle size qualification rate, and ensures the quality of the manganese oxide abrasive.

[0045] The removable baffle 10 set at the right end of the manganese oxide guide frame 2 can be easily removed after the device completes the screening operation, so that the material remaining inside the manganese oxide guide frame 2 and the manganese oxide conveying cylinder 3 can be easily removed. This design simplifies the cleaning process, reduces the risk of equipment failure caused by residual materials, reduces the frequency and cost of maintenance, and extends the service life of the equipment.

[0046] By integrating grinding and screening functions into the same screening box 1, the floor space is significantly reduced compared to traditional separate equipment, and the production layout is optimized. At the same time, the number of material transfer links between different equipment is reduced, further reducing material loss and transmission energy consumption, and improving the overall compactness and space utilization of the production system.
