Description
Technical Field
[0001] This utility model relates to the field of mineral processing technology, and more specifically, to a multi-stage separator for phosphorus beneficiation of concentrated magnetic tailings. Background Technology
[0002] The multi-stage separator for phosphorus extraction from concentrated magnetic tailings is specifically designed for this purpose. Utilizing physical principles such as magnetism and gravity, it employs multiple separation units (e.g., crushers, magnetic separators, classifiers) to continuously and stably classify and separate the tailings, gradually enriching them with phosphorus and producing high-grade phosphate rock. This equipment is highly efficient, energy-saving, environmentally friendly, and adaptable, capable of processing tailings of different particle sizes and properties. It is widely used in the field of phosphate resource recovery and utilization, providing key raw material support for phosphate fertilizer production and effectively promoting the sustainable utilization of phosphorus resources. In existing technologies, before processing concentrated magnetic tailings, the separator typically requires crushing. To improve crushing efficiency, operators often directly pour the tailings into the crusher. However, this often leads to material accumulation inside the crusher. This accumulation not only results in uneven crushing, affecting subsequent tailings separation, but also increases equipment wear and reduces overall processing efficiency. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. Compared with traditional separators, this utility model uses two crushing wheels to crush concentrated magnetic tailings. By crushing the concentrated magnetic tailings, the tailings particle size is significantly reduced and becomes more uniform, which helps improve the grading efficiency of subsequent sorting processes. At the same time, the use of a diversion plate slowly and evenly introduces the tailings between the two crushing devices, ensuring the continuity and stability of the crushing process and improving crushing efficiency.

Secondly, the collection box is located at the bottom of the grading box, which helps the continuous sorting process to proceed smoothly, while reducing the interference of external factors on the sorting process, improving the accuracy and stability of sorting. Finally, this design optimizes the space layout, reduces the floor space, lowers equipment and operating costs, and facilitates maintenance and cleaning, further reducing maintenance costs, making the entire sorting system more compact, efficient, and economical.

[0025] like Figures 1 to 8 As shown, this utility model provides a multi-stage separator for phosphorus beneficiation of concentrated magnetic tailings, including a support platform 1, a grading box 2 fixedly installed on the top of the support platform 1, a crushing box 3 fixedly installed on the top of the grading box 2, a rotating shaft 32 movably installed inside the crushing box 3, and both ends of the rotating shaft 32 passing through the interior of the crushing box 3, a driven wheel 7 fixedly installed at one end of the rotating shaft 32, and a motor 9 fixedly installed on the left side of the crushing box 3, and one end of the motor 9 fixedly connected to the other end of the diverter plate 31;
[0026] The crushing box 3 is movably mounted with a rotating shaft 2 33, and both ends of the rotating shaft 2 33 pass through the interior of the crushing box 3. A drive wheel 6 is fixedly mounted on one end of the rotating shaft 2 33. A transmission belt 8 is connected between the drive wheel 6 and the driven wheel 1 7. A driven wheel 3 23 is fixedly mounted on the other end of the rotating shaft 2 33. A feed inlet 4 is fixedly mounted on the top of the crushing box 3. A rotating shaft 3 34 is movably mounted inside the feed inlet 4, and both ends of the rotating shaft 3 34 pass through the interior of the feed inlet 4. A driven wheel 2 21 is fixedly mounted on one end of the rotating shaft 3 34. A transmission belt 2 22 is connected between the driven wheel 2 21 and the driven wheel 3 23.
[0027] Before classifying the concentrated magnetic tailings, the workers need to crush them. First, the concentrated magnetic tailings are poured into the feed inlet 4, and then the motor 9 is turned on. This drives the rotating shaft 23 and the crushing wheel 28 to rotate synchronously. The crushing wheel 28 drives the drive wheel 6 to rotate, and the drive wheel 6 drives the conveyor belt 1 8 and the driven wheel 1 7 to rotate synchronously. The driven wheel 1 7 drives the rotating shaft 1 32 and the rotating shaft 2 33 inside the crushing box 3. The teeth of the two crushing wheels 28 mesh to facilitate timely crushing of the concentrated magnetic tailings. The rotating shaft 1 32 drives the driven wheel 3 23 to rotate, and the driven wheel 3 23 drives the conveyor belt 2 22 and the driven wheel 2 21 to rotate synchronously. The driven wheel 2 21 drives the rotating shaft 3 34 to rotate inside the feed inlet 4. The rotating shaft 3 34 drives the diversion plate 31 to rotate, and the diversion plate 31 diverts the concentrated magnetic tailings, thus completing the crushing of the concentrated magnetic tailings.
[0028] Before classifying the concentrated magnetic tailings, they need to be crushed. First, the concentrated magnetic tailings are poured into the feed inlet 4. Then, the motor 9 is turned on, driving the rotating shaft 23 and the crushing wheel 28 to rotate synchronously. The crushing wheel 28 drives the drive wheel 6 to rotate, which in turn drives the conveyor belt 1 and the driven wheel 7 to rotate synchronously. The driven wheel 7 then drives the rotating shaft 1 32 and the rotating shaft 2 33 inside the crushing box 3. Through the meshing of the teeth between the two crushing wheels 28, the rotating shaft 1 32 drives the driven wheel 3 23 to rotate. The driven wheel 3 23 then drives the conveyor belt 2 22 and the driven wheel 2 21 to rotate synchronously. The driven wheel 2 21 then drives the rotating shaft 3 34 to rotate inside the feed inlet 4. Finally, the rotating shaft 3 34 drives the... The flow plate 31 rotates, diverting the concentrated magnetic tailings through the diversion plate 31. Compared with traditional separators, this separator uses two crushing wheels 28 to crush the concentrated magnetic tailings. By crushing the concentrated magnetic tailings, the tailings particle size is significantly reduced and becomes more uniform, which helps improve the classification efficiency of subsequent separation processes. At the same time, the use of the diversion plate 31 slowly and evenly introduces the tailings between the two crushing devices, ensuring the continuity and stability of the crushing process and improving crushing efficiency. This particle size uniformity not only improves the separation accuracy and yields high-quality phosphate rock products, but also reduces the loss of useful minerals, increases the recovery rate, and brings greater economic benefits to enterprises. In addition, the optimized crushing process reduces energy consumption, extends equipment life, and reduces maintenance and replacement costs, demonstrating the energy-saving and economical nature of the equipment.
[0029] The bottom of the grading box 2 is fixedly installed with a fixed base 12. The fixed base 12 has a sliding groove 11 inside. The collection box 13 is movably installed inside the sliding groove 11. The box body 14 is fixedly installed on the outside of the fixed base 12. The collection box 13 has a positioning hole 5 inside. The positioning hole 5 has a limit block 25 movably installed inside. One end of the limit block 25 is fixedly installed with a pull rod 26, and one end of the pull rod 26 passes through the inside of the box body 14. A spring 27 is fixedly installed between the limit block 25 and the box body 14. A push rod 24 is fixedly installed on the front of the collection box 13. Crushing wheels 28 are fixedly installed on the outer surfaces of the second rotating shaft 33 and the first rotating shaft 32. The grading box 2 is equipped with a vibration component inside.
[0030] Before crushing the concentrated magnetic tailings, the workers need to install the collection box 13 at the bottom of the fixed base 12 to collect the concentrated magnetic tailings after grading. By holding the pull rod 26, the limit block 25 is moved inside the fixed base 12. The limit block 25 compresses the spring 27, causing the limit block 25 to pass through the inside of the fixed base 12 and enter the inside of the box 14. Now, by holding the push rod 24, the collection box 13 is pushed into the inside of the slide 11. When the collection box 13 is completely inside the slide 11, the pull rod 26 is released, and the spring 27 compresses the limit block 25, causing the limit block 25 to quickly enter the inside of the positioning hole 5. The limit block 25 limits and fixes the collection box 13. Then, the vibration component is turned on to grade the concentrated magnetic tailings, thus completing the installation of the collection box 13.
[0031] Before crushing the concentrated magnetic tailings, the collection box 13 needs to be installed at the bottom of the fixed base 12 to collect the concentrated magnetic tailings after grading. By holding the pull rod 26, the limit block 25 is moved inside the fixed base 12. The limit block 25 compresses the spring 27, causing the limit block 25 to pass through the inside of the fixed base 12 and enter the inside of the box 14. Now, by holding the push rod 24, the collection box 13 is pushed into the chute 11. The pull rod 26 is released, and the spring 27 compresses the limit block 25, causing the limit block 25 to quickly enter the inside of the positioning hole 5. The limit block 25 limits and fixes the collection box 13. Compared with traditional separators, this separator uses the positioning hole... 5. The cooperation between the limiting block 25 and the spring 27 facilitates the installation of the collection box 13 at the bottom of the fixed base 12, ensuring that the tailings can fall directly into the collection box 13 during the grading process, effectively preventing the scattering and loss of tailings, improving collection efficiency, and facilitating the unified treatment, transportation, storage, or reuse of tailings. Secondly, the collection box 13 is located at the bottom of the grading box, which helps the continuous sorting process to proceed smoothly, while reducing the interference of external factors on the sorting process, improving the accuracy and stability of sorting. Finally, this design optimizes the space layout, reduces the floor space, lowers equipment and operating costs, and facilitates maintenance and cleaning, further reducing maintenance costs, making the entire sorting system more compact, efficient, and economical.
[0032] The vibration assembly is located inside the grading box 2. The vibration assembly includes a screen 29 that is movably installed inside the grading box 2. A vibration motor 30 is fixedly installed at the bottom of the screen 29.
[0033] After the crushing of concentrated magnetic tailings for phosphorus beneficiation is completed, the tailings enter the classifying box 2 through the crushing box 3. Now, the staff turns on the vibration motor 30. The vibration motor 30 vibrates the screen 29, which filters the concentrated magnetic tailings for phosphorus beneficiation. The size of the openings inside the screen 29 decreases from large to small as they fall through the screen 29, thus classifying the concentrated magnetic tailings for phosphorus beneficiation. The smallest concentrated magnetic tailings for phosphorus beneficiation slowly flow into the collection box 13 through the fixed base 12, thereby completing the classification of the concentrated magnetic tailings for phosphorus beneficiation.
[0034] The support platform 1 has a support plate 15 fixedly installed at its bottom, and a connecting plate 17 is fixedly installed between the two support plates 15.
[0035] The cooperation between the support plate 15 and the connecting plate 17 facilitates stable support for the support platform 1. The support platform 1 supports the grading box 2 and the crushing box 3, ensuring the stability of the grading box 2 and the support platform 1 during use, and ensuring the efficiency of the support platform 1 and the grading box 2 during use.
[0036] The support platform 1 has a fixing groove 20 inside, and a fixing block 19 is movably installed inside the fixing groove 20. A toolbox 18 is fixedly installed on the left side of the fixing block 19.
[0037] By holding the toolbox 18, the fixing block 19 is slowly placed into the fixing slot 20. The fixing slot 20 limits and fixes the fixing block 19 and the toolbox 18. By adding the toolbox 18, it is easier for the staff to take out and put away maintenance tools.
[0038] A reinforcing rib 16 is fixedly installed at the angle between the support plate 15 and the connecting plate 17, and the reinforcing rib 16 is triangular in shape.
[0039] Since the reinforcing rib 16 is triangular in shape at the angle between the support plate 15 and the connecting plate 17, and the triangle has the characteristic of stability, the swaying of the support plate 15 and the connecting plate 17 during use is reduced.
[0040] The left side of the crushing box 3 is fixedly equipped with a support base 10, and the inside of the support base 10 has a U-shaped form.
[0041] Since the support base 10 is U-shaped on the left side of the crushing box 3, it provides stable support for the motor 9, avoids the motor 9 from shaking during use, and improves the stability of the motor 9 during use.
[0042] Working principle and usage process of this utility model:
[0043] Before classifying the concentrated magnetic tailings, the workers need to crush them. First, the concentrated magnetic tailings are poured into the feed inlet 4, and then the motor 9 is turned on. This drives the rotating shaft 23 and the crushing wheel 28 to rotate synchronously. The crushing wheel 28 drives the drive wheel 6 to rotate, and the drive wheel 6 drives the conveyor belt 1 8 and the driven wheel 1 7 to rotate synchronously. The driven wheel 1 7 drives the rotating shaft 1 32 and the rotating shaft 2 33 inside the crushing box 3. The teeth of the two crushing wheels 28 mesh to facilitate timely crushing of the concentrated magnetic tailings. The rotating shaft 1 32 drives the driven wheel 3 23 to rotate, and the driven wheel 3 23 drives the conveyor belt 2 22 and the driven wheel 2 21 to rotate synchronously. The driven wheel 2 21 drives the rotating shaft 3 34 to rotate inside the feed inlet 4. The rotating shaft 3 34 drives the diversion plate 31 to rotate, and the diversion plate 31 diverts the concentrated magnetic tailings, thus completing the crushing of the concentrated magnetic tailings.
[0044] Before crushing the concentrated magnetic tailings, the workers need to install the collection box 13 at the bottom of the fixed base 12 to collect the concentrated magnetic tailings after grading. By holding the pull rod 26, the limit block 25 is moved inside the fixed base 12. The limit block 25 compresses the spring 27, causing the limit block 25 to pass through the inside of the fixed base 12 and enter the inside of the box 14. Now, by holding the push rod 24, the collection box 13 is pushed into the inside of the slide 11. When the collection box 13 is completely inside the slide 11, the pull rod 26 is released, and the spring 27 compresses the limit block 25, causing the limit block 25 to quickly enter the inside of the positioning hole 5. The limit block 25 limits and fixes the collection box 13. Then, the vibration component is turned on to grade the concentrated magnetic tailings, thus completing the installation of the collection box 13.
