Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining equipment technology, specifically to centrifugal flotation machines. Background Technology
[0002] A flotation machine, short for flotation mineral processing machine, refers to mechanical equipment that completes the flotation process. In a flotation machine, after the slurry has been treated with reagents, it is stirred and aerated, causing some mineral particles to selectively adhere to the air bubbles and float horizontally to the surface of the slurry, where they are scraped off to form a froth product. The rest remain in the slurry, thus achieving the purpose of separating minerals.
[0003] In centrifugal flotation machines, the scraper, air inlet pipe, and feed pipe are key components, directly affecting flotation efficiency and equipment performance. However, existing scraper structures are fixed, and the contact area between the scraper and the slurry is limited, resulting in limited scraping capacity, low adaptability and reliability, and inconvenient maintenance and cleaning. These problems lead to low separation efficiency and poor equipment reliability. Therefore, a more efficient and reliable centrifugal flotation machine is needed. Utility Model Content
[0004] The technical problem this invention aims to solve is that the fixed scraper structure results in low sorting efficiency and poor equipment reliability. This invention provides a highly efficient and reliable centrifugal flotation machine.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a centrifugal flotation machine, including a flotation machine body, a feed box connected to one outer wall of the flotation machine body, a feed pipe cooperating with the feed box inside the flotation machine body, a set of air inlet pipes on the flotation machine body, a flotation cell connected to the flotation machine body, a guide plate cooperating with the flotation cell on the flotation machine body, a scraper rotatably installed inside the flotation cell, a drive mechanism for driving the scraper on the side wall of the flotation machine body, and an adjustment mechanism cooperating with the scraper inside the flotation cell. The adjustment mechanism includes a first rotating rod and a second rotating rod rotatably connected to the inner walls of both sides of the flotation cell, respectively. The drive mechanism is located at the flotation cell... The main body of the machine is fixedly connected to the first rotating rod. The other end of the first rotating rod is fixedly provided with a first adjusting groove. A first adjusting block is slidably provided in the first adjusting groove. The other end of the first adjusting block is provided with a fixed sleeve. The scraper is provided with a connecting post extending into the fixed sleeve. Multiple connecting holes are circumferentially distributed on the connecting post. A connecting bolt that mates with the connecting holes is passed through the fixed sleeve. The other end of the second rotating rod is fixedly provided with a second adjusting groove. A second adjusting block is slidably provided in the second adjusting groove. A U-shaped connector is rotatably provided at the other end of the second adjusting block. The other end of the scraper is fitted into the U-shaped connector. The U-shaped connector and the scraper are connected by bolts.
[0006] As an improvement, a filter is fitted at the air intake end of the air intake pipe. Installing a filter at the inlet of the air intake pipe can filter out dust and impurities in the air, reducing wear and clogging of the equipment.
[0007] As an improvement, the top surfaces of the first and second adjustment slots are both connected by through slots. An adjustment plate that is slidably connected to the first and second adjustment blocks is provided in the through slot. The top surfaces of the first and second adjustment slots are evenly provided with multiple adjustment holes. Adjustment bolts that are threadedly connected to the adjustment holes are provided through the adjustment plates, which can realize the adjustment and fixation of the scraper position and improve the reliability of the equipment.
[0008] As an improvement, the driving mechanism includes a drive motor fixedly mounted on the outer wall of the flotation machine body. The output end of the drive motor is connected to a main pulley. The outer wall of the flotation machine body is rotatably provided with a driven pulley fixedly connected to the first rotating rod. A drive belt is provided between the main pulley and the driven pulley. Since the belt has good elasticity, it can absorb and mitigate the impact and vibration during the transmission process, making the transmission smoother and thus improving the stability of the equipment.
[0009] As an improvement, a first flow meter is embedded in the center of the air inlet pipe, and a second flow meter is embedded in the ore feed pipe. The flow meters, together with the equipment controller, can achieve precise control of the gas and slurry flow rates, thereby improving the stability of the separation effect.
[0010] As an improvement, the scraper has an arc-shaped structure, and the surface of the scraper is coated with a wear-resistant coating. Using an arc-shaped scraper can improve the scraping efficiency and effect of the scraper. By applying a wear-resistant coating to the scraper, the wear resistance of the scraper can be increased, thereby extending the service life of the scraper.
[0011] The advantages of this utility model compared with the prior art are: by optimizing the structural design of the scraper, the position and angle of the scraper can be adjusted, thereby changing the contact area and speed between the scraper and the slurry, improving the scraping capacity and reliability of the scraper, and at the same time realizing the disassembly and cleaning of the scraper, thereby reducing the workload and cost of equipment maintenance.
[0012] Adding a first flow meter and a second flow meter to the air inlet pipe and the ore feed pipe improves the uniformity of slurry flow and the separation effect. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.
[0020] Example 1
[0021] Combined with appendix Figure 1-3 As shown, a centrifugal flotation machine includes a flotation machine body 1. A feed box 2 is connected to one outer wall of the flotation machine body 1. A feed pipe 3 that cooperates with the feed box 2 is provided inside the flotation machine body 1. A set of air inlet pipes 4 are provided on the flotation machine body 1. A filter 21 is fitted at the air inlet end of the air inlet pipe 4. A first flow meter 30 is embedded in the center of the air inlet pipe 4. A second flow meter 31 is embedded in the feed pipe 3. A flotation cell 5 is connected to the flotation machine body 1. A guide plate 6 that cooperates with the flotation cell 5 is provided on the flotation machine body 1. A scraper 7 is rotatably provided inside the flotation cell 5. A drive plate is provided on the side wall of the flotation machine body 1. The driving mechanism 8 of the moving scraper 7 is provided. The flotation tank 5 is provided with an adjustment mechanism 9 that cooperates with the scraper 7. The adjustment mechanism 9 includes a first rotating rod 10 and a second rotating rod 11 that are rotatably connected to the inner walls of both sides of the flotation tank 5. The driving mechanism 8 is located on the side wall of the flotation machine body 1 and is fixedly connected to the first rotating rod 10. The driving mechanism 8 includes a driving motor 26 that is fixedly installed on the outer wall of the flotation machine body 1. The output end of the driving motor 26 is connected to a main pulley 27. The outer wall of the flotation machine body 1 is rotatably provided with a driven pulley 28 that is fixedly connected to the first rotating rod 10. A driving belt 29 is provided between the main pulley 27 and the driven pulley 28.
[0022] With the above structure, during use, the slurry is poured into the feed box 2, and the negative pressure generated by the rotation of the impeller of the flotation machine body 1 is drawn into the flotation machine body 1. During the suction process, the second flow meter 31 detects the amount of slurry, and at the same time, air is introduced into the flotation machine body 1 through the air inlet pipe 4 at regular intervals. The filter 21 filters out dust and impurities in the air, reducing wear and blockage of the equipment. The first flow meter 30 and the second flow meter 31, together with the equipment controller, can achieve precise control of the gas and slurry flow. After the flotation machine body 1 has worked, the concentrate foam finally overflows from the flotation cell 5. The drive motor 26 is turned on, so that the main pulley 27 drives the secondary pulley 28 to rotate under the action of the drive belt 29, thereby causing the scraper 7 to rotate and take out the concentrate foam through the guide plate 6, thus realizing the flotation operation.
[0023] Example 2
[0024] Based on Example 1, combined with Appendix Figure 4 and 5 As shown, the first rotating rod 10 has a first adjusting groove 12 fixedly provided at its other end. A first adjusting block 13 is slidably provided in the first adjusting groove 12. A fixing sleeve 14 is provided at the other end of the first adjusting block 13. A connecting post 15 extending into the fixing sleeve 14 is provided on the scraper 7. A plurality of connecting holes 16 are circumferentially distributed on the connecting post 15. A connecting bolt 17 that mates with the connecting holes 16 is provided through the fixing sleeve 14. The second rotating rod 11 has a second adjusting groove 18 fixedly provided at its other end. A second adjusting block 19 is slidably provided in the second adjusting groove 18. The second adjusting block 19 has a rotating groove 18 at its other end. The scraper 7 is equipped with a U-shaped connector 20, and the other end of the scraper 7 is fitted into the U-shaped connector 20. The U-shaped connector 20 and the scraper 7 are connected by bolts. The top surfaces of the first adjustment groove 12 and the second adjustment groove 18 are both connected by through grooves 22. An adjustment plate 23 connected to the first adjustment block 13 and the second adjustment block 19 is slidably installed in the through groove 22. The top surfaces of the first adjustment groove 12 and the second adjustment groove 18 are evenly provided with multiple adjustment holes 24. An adjustment bolt 25 threadedly connected to the adjustment hole 24 is threaded through the adjustment plate 23. The scraper 7 has an arc-shaped structure and the surface of the scraper 7 is coated with a wear-resistant coating.
[0025] With the above structure, before use, the scraper 7, coated with a wear-resistant coating, is slidably placed inside the U-shaped connector 20. The scraper 7 is pushed so that the connecting post 15 enters the fixing sleeve 14. A bolt is used to initially limit and fix the scraper 7 through the U-shaped connector 20. Then, the connecting post 15 can be rotated within the fixing sleeve 14 to adjust the angle of the scraper 7. During adjustment, the U-shaped connector 20 rotates in conjunction with the scraper 7 until the desired angle is achieved. Finally, the connecting bolt 17 is used to connect the fixing sleeve 14 to the corresponding connecting hole 16, completing the angle adjustment operation of the scraper 7. When the position of the scraper 7 needs to be finely adjusted, the scraper 7 is pushed so that the first adjusting block 13 slides in the first adjusting groove 12 and the second adjusting block 19 slides in the second adjusting groove 18. After adjusting to the required position, the adjusting bolt 25 is threaded through the adjusting plate 23 and connected to the corresponding adjusting hole 24 to complete the adjustment operation. After adjustment, the scraping ability and reliability of the scraper 7 are improved, thereby improving the sorting efficiency. The arc-shaped scraper 7 is used to improve the scraping efficiency and effect of the scraper 7. The wear-resistant coating increases the wear resistance of the scraper 7, thereby extending the service life of the scraper 7.
[0026] In specific implementation of this utility model, before use, the scraper 7 coated with a wear-resistant coating is slidably placed inside the U-shaped connector 20. The scraper 7 is pushed so that the connecting column 15 enters the fixed sleeve 14. The scraper 7 is initially limited and fixed by using bolts through the U-shaped connector 20. Then, the connecting column 15 can be rotated inside the fixed sleeve 14 to adjust the angle of the scraper 7. During the adjustment process, the U-shaped connector 20 rotates in coordination with the scraper 7 until the required angle is reached. The connecting bolt 17 is used to pass through the fixed sleeve 14 and connect to the corresponding connecting hole 16 to complete the angle adjustment operation of the scraper 7. When it is necessary to fine-tune the position of the scraper 7, the scraper 7 is pushed so that the first adjusting block 13 slides in the first adjusting groove 12 and the second adjusting block 19 slides in the second adjusting groove 18. After adjusting to the required position, the adjusting bolt 25 is used to pass through the adjusting plate 23 and connect to the corresponding adjusting hole 24 to complete the adjustment operation. Thus, the sorting efficiency can be improved according to the sorting requirements.
[0027] During operation, the slurry is poured into the feed box 2, and the negative pressure generated by the rotation of the impeller of the flotation machine body 1 is drawn into the flotation machine body 1. During the suction process, the second flow meter 31 detects the amount of slurry. At the same time, air is introduced into the flotation machine body 1 through the air inlet pipe 4 at regular intervals. The filter 21 filters out dust and impurities in the air, reducing wear and blockage of the equipment. The first flow meter 30 and the second flow meter 31, together with the equipment controller, can achieve precise control of the gas and slurry flow. After the flotation machine body 1 has worked, the concentrate foam overflows from the flotation cell 5. The drive motor 26 is turned on, so that the main pulley 27 drives the secondary pulley 28 to rotate under the action of the drive belt 29. This causes the scraper 7 to rotate and remove the concentrate foam through the guide plate 6. The arc-shaped scraper 7 improves the scraping efficiency and effect. The wear-resistant coating increases the wear resistance of the scraper 7, thereby extending the service life of the scraper 7 and realizing the flotation operation.
[0028] After use, remove the bolts on the U-shaped connector 20, then remove the connecting bolts 17 on the fixing sleeve 14. Then, pull the connecting post 15 on the scraper 7 out of the fixing sleeve 14. Finally, slide the scraper 7 off the U-shaped connector 20 to complete the disassembly of the scraper 7. Then, it can be cleaned. At the same time, the filter 21 can be removed for inspection and replacement to ensure dust isolation quality.
[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
