Description

Technical Field

[0001] This utility model relates to the technical field of mineral crushing and sorting equipment, specifically to a high-efficiency crushing and sorting equipment for germanium concentrate. Background Technology

[0002] In the processing of germanium concentrate, crushing and sorting are crucial steps, as their effectiveness directly affects the smooth progress of subsequent processes and the quality of the final product. Traditional germanium concentrate crushing equipment often employs a single crushing method with a relatively simple crushing structure, making it difficult to achieve step-by-step crushing of materials. This results in significant differences in particle size among the crushed materials, affecting not only the crushing quality but also reducing crushing efficiency.

[0003] In the sorting stage, traditional equipment mostly relies on manual screening or simple static screening devices. Manual screening is not only labor-intensive and inefficient, but also easily affected by human factors. Static screening devices suffer from material accumulation, and the material cannot be evenly dispersed during the screening process, causing some material to fail to pass through the screen holes in time, reducing sorting efficiency and affecting sorting accuracy, making it difficult to separate germanium concentrate particles of different sizes.

[0004] In view of this, we propose a high-efficiency crushing and sorting equipment for germanium concentrate. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency crushing and sorting device for germanium concentrate to address the aforementioned shortcomings in the technology.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By setting corresponding crushing tooth rings and conical crushing discs with progressively smaller gaps inside the crushing barrel, germanium concentrate can be crushed efficiently and precisely in stages, effectively improving crushing quality and efficiency, and making the material particle size more uniform.

[0028] Example 1: Refer to the appendix of the instruction manual. Figure 1-7 The high-efficiency crushing and sorting equipment for germanium concentrate includes a crushing barrel 1 and a screening cylinder 9. The bottom side of the crushing barrel 1 is connected to the top side of the screening cylinder 9. Three equally spaced crushing tooth rings 2 are fixedly installed on the inner wall of the crushing barrel 1. A vertically upward servo motor 3 is fixedly installed inside the crushing barrel 1 through a bracket. The output end of the servo motor 3 is fixedly connected to a vertically upward first rotating rod 4 through a reducer. Three equally spaced conical crushing discs 5 are fixed on the outer wall of the first rotating rod 4. Each conical crushing disc 5 has equally spaced teeth for crushing on its outer wall. The inner wall of the three crushing tooth rings 2 and the outer wall of the three conical crushing discs 5 are fitted with a clearance, and the distance between them gradually decreases from top to bottom, which is beneficial for the step-by-step crushing of germanium concentrate and improves the crushing effect.

[0029] Example 2: Based on Example 1, a feeding hopper 6 is fixedly provided on the top outer wall of the crushing barrel 1 for feeding germanium concentrate into the crushing barrel 1. A positioning ring 7 is movably connected to the top outer wall of the first rotating rod 4. Three equally spaced support rods 8 are fixedly provided on the outer wall of the positioning ring 7. The outer wall of the other end of the support rod 8 is fixedly connected to the inner wall of the feeding hopper 6 to improve the stability of the first rotating rod 4 during rotation.

[0030] Example 3: Based on Example 1, a motor mounting cover 10 is fixedly installed on the outer wall of one end of the screening cylinder 9. The outer wall of the motor mounting cover 10 has evenly spaced heat dissipation holes. The motor 11 is installed inside the motor mounting cover 10. The output end of the motor 11 passes through the outer wall of the screening cylinder 9 and is fixedly connected to a second rotating rod 12 via a coupling. A conveying auger 13 is fixedly installed on the outer wall of the second rotating rod 12. The conveying auger 13 can transport the crushed germanium concentrate from the crushing barrel 1 into the screening cylinder 9 and push the material to move within the screening cylinder 9. Bearings 15 are evenly spaced installed on the inner wall of the screening cylinder 9 away from the crushing barrel 1. The inner wall of the bearings 15 is fixed... A screen cylinder 14 is provided, and the outer wall of the screen cylinder 14 is provided with a first mesh, a second mesh, a third mesh and a fourth mesh, which are distributed at equal intervals. The aperture of the first mesh, the second mesh, the third mesh and the fourth mesh increases step by step. They are located between adjacent bearings 15. This design allows germanium concentrate particles of different sizes to be separated by passing through meshes of different apertures. The bottom of the screening cylinder 9 is connected to four discharge pipes 19 distributed at equal intervals through an opening. Valves are installed on the discharge pipes 19. The four discharge pipes 19 are located at the bottom of the first mesh, the second mesh, the third mesh and the fourth mesh, respectively, and are used to discharge the germanium concentrate particles of different sizes after separation.

[0031] Example 4: Based on Example 1, a drive gear 17 is fixedly provided on the outer wall of one end of the second rotating rod 12, and an internal gear ring 16 is fixedly provided on the inner wall of one end of the screen cylinder 14. A planetary gear 18 is movably connected to the outer wall of one end of the screening cylinder 9 through an opening using a rotating shaft. The drive gear 17 meshes with the planetary gear 18, and the planetary gear 18 meshes with the internal gear ring 16. When the second rotating rod 12 rotates, the screen cylinder 14 is driven to rotate through the transmission of the drive gear 17, the planetary gear 18 and the internal gear ring 16, thereby improving the sorting efficiency of germanium concentrate particles.

[0032] Working principle of this utility model:

[0033] Refer to the instruction manual appendix Figure 1-7 First, the germanium concentrate to be processed is fed into the crushing barrel 1 through the feeding hopper 6. Then, the servo motor 3 is started. The servo motor 3 drives the first rotating rod 4 and the three conical crushing discs 5 fixed on it to rotate through the reducer. The teeth on the outer wall of the conical crushing disc 5 interact with the crushing tooth ring 2 on the inner wall of the crushing barrel 1 to crush the germanium concentrate step by step. The gap between the crushing tooth ring 2 and the conical crushing disc 5 is designed to gradually decrease from top to bottom, so that the material is continuously refined during the crushing process.

[0034] After the germanium concentrate is crushed to a suitable particle size, the material enters the screening cylinder 9 from the bottom of the crushing barrel 1 under the push of the conveying auger 13. At this time, the motor 11 is started, and the motor 11 drives the second rotating rod 12 to rotate, thereby causing the conveying auger 13 to continuously convey the material. At the same time, the drive gear 17 at one end of the second rotating rod 12 meshes with the internal gear ring 16 at one end of the screen cylinder 14 through the planetary gear 18, driving the screen cylinder 14 to rotate. The first, second, third and fourth meshes of different diameters on the outer wall of the screen cylinder 14 classify and screen the material during the rotation. Germanium concentrate particles of different sizes fall into the bottom of the screening cylinder 9 through the meshes of the corresponding diameters. The valve on the discharge pipe 19 is opened to discharge and collect the sorted germanium concentrate particles of different sizes, completing the entire crushing and sorting operation process.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
