Description

[0001] A flotation machine impeller with a double blade structure Technical Field

[0002] This utility model relates to the technical field of flotation machine impellers, and in particular to a flotation machine impeller with a double-blade structure. Background Technology

[0003] The double-blade flotation impeller is an important mechanical component in the mineral flotation process. It consists of two blades (the two main parts of the impeller) designed to generate appropriate liquid flow and bubble distribution inside the flotation machine, thereby achieving effective separation of minerals and flotation agents. The rotation of the impeller drives the gas and liquid suspended in the slurry to mix thoroughly, forming a large number of fine and uniformly distributed bubbles that contact and adhere to the mineral particles. The double-blade design optimizes the flow field to ensure sufficient contact between bubbles and mineral particles, promoting mineral separation.

[0004] Referring to patent CN220836097U, a flotation machine impeller with a double-blade structure is disclosed, including a fixing ring, a fixing bolt, and a fixing plate. The fixing bolt is connected to the fixed end of the fixing ring, and the fixing plate is fixedly installed on the outer wall of the fixing ring. An installation mechanism is provided at the top of the fixing plate. This double-blade flotation machine impeller, by providing an installation mechanism, allows the position of the blades to be adjusted within a certain range before the device is used, thereby increasing the contact area between the blades and the material, thus improving the practical performance of the device. It solves the problem mentioned in the prior art where the device is not convenient for adjusting the position of the blades, thus limiting the contact area of ​​the blades. This device is not only simple in structure but also allows for quick and convenient installation at the fixed end. Furthermore, the device facilitates blade replacement, allowing for the use of blades of different sizes, further improving the practical performance of the device.

[0005] Existing impellers are all fixed inside the flotation machine, and the height of the impellers is fixed, making it impossible to adjust the impeller immersion depth according to the properties of the slurry or process requirements. At the same time, because different types of ore or different flotation stages require different stirring intensities and gas-liquid mixing conditions, when the impeller is of a fixed height, it leads to over-stirring or under-stirring, resulting in uneven bubble generation. Utility Model Content

[0006] Given that the height of the impeller in the existing double-blade flotation machine is fixed, making it impossible to adjust the impeller immersion depth according to the slurry or process requirements, and that different ore types or different flotation stages require different stirring intensities and gas-liquid mixing conditions, resulting in uneven bubble generation, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flotation machine impeller with a double blade structure, including a base, a bearing for connection is fixedly installed on the outer side of the base, and a first mounting rod is slidably connected inside the base, and a fixing component is provided at the right end of the first mounting rod. A mounting hole is opened at the bottom of the first mounting rod, and a second mounting rod is inserted into the mounting hole. The upper end of the first mounting rod has fixing holes in an array, and the lower end of the first mounting rod is sleeved and connected to the impeller body. Sleeves are fixedly installed on both the first and second mounting rods, and a mounting component is provided on the outer side of the sleeve.

[0008] In this example, the upper diameter of the second mounting rod is the same as the inner diameter of the mounting hole, and a fixing bolt is inserted into the left end of the lower end of the first mounting rod, and the fixing bolt extends through the second mounting rod to the right end of the first mounting rod.

[0009] In this example, the fixing component includes a support plate. The support plate is fixedly installed on the upper end of the right end of the base, and the plate body of the support plate has a through groove. A threaded rod is rotatably connected in the groove, and a push plate is threadedly connected to the rod body of the threaded rod.

[0010] In this example, a limiting rod is fixedly installed on the left end of the push plate. The diameter of the limiting rod is the same as the diameter of the fixing hole, and the limiting rod and the fixing hole are engaged.

[0011] In this example, the mounting assembly includes a support frame, with support frames fixedly mounted on both the left and right ends of the sleeve. A limit pin is slidably connected to the frame of the support frame, and a spring is sleeved and connected to the outer side of the limit pin rod.

[0012] In this example, the inner diameter of the impeller body is the same as the outer diameter of the first mounting rod, and the outer diameter of the impeller body is the same as the inner diameter of the sleeve.

[0013] In this example, the rod of the limiting pin passes through the impeller body, and the rod of the limiting pin is engaged with the first mounting rod.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] 1. The limiting rod of this utility model is engaged with the fixing hole. By rotating the threaded rod, the rod body is connected to the push plate through the thread. When the threaded rod is rotated, the push plate slides in the groove of the through slot. The movement of the push plate causes the limiting rod to slide, thereby releasing the fixation of the first mounting rod. The sliding of the first mounting rod inside the base allows it to be pushed or pulled according to the actual situation, thereby adjusting the impeller body. By adjusting the depth of the impeller body, the air shear force can be precisely controlled to facilitate the generation of bubbles of appropriate size, thereby increasing the collision probability between minerals and bubbles, improving mineral efficiency, and adapting to diverse ore and process requirements.

[0016] 2. This utility model involves pulling the limiting pin on the support frame, causing the limiting pin to simultaneously compress the spring, thereby releasing the fixation on the impeller body and allowing for disassembly of the impeller body. Since the inner diameter of the impeller body matches the outer diameter of the first mounting rod, and the outer diameter of the impeller body matches the inner diameter of the sleeve, the impeller body can be fitted onto the first mounting rod and placed within the inner cavity of the sleeve. Simultaneously, the spring force drives the limiting pin to reset, causing the limiting pin to penetrate the impeller body and engage with the first mounting rod, thus completing the installation of the impeller body. Pulling the limiting pin allows for quick replacement of the impeller body, reducing downtime and simplifying the impeller replacement process, thereby ensuring the continuous and stable operation of the flotation machine.

[0017] 3. In this utility model, the upper diameter of the second mounting rod is consistent with the inner diameter of the mounting hole, so the second mounting rod can be inserted into the mounting hole. The second mounting rod is fixed together with the first mounting rod by a fixing bolt. At the same time, a sleeve is also fixedly installed on the second mounting rod, so an impeller body can be installed on the second mounting rod. By adding an impeller body, the bubble dispersion and flow field distribution can be further improved, thereby enhancing the flotation effect of minerals and ensuring that mineral particles and bubbles are in full contact.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a flotation machine impeller with a double-blade structure. This double-blade flotation machine impeller includes a base 1, a bearing 2 for connection is fixedly installed on the outer side of the base 1, and a first mounting rod 3 is slidably connected inside the base 1. A fixing component is provided at the right end of the first mounting rod 3. A mounting hole 4 is opened at the bottom of the first mounting rod 3, and a second mounting rod 16 is inserted into the mounting hole 4. The upper end of the first mounting rod 3 has fixing holes 5 in an array state, and the lower end of the first mounting rod 3 is sleeved and connected to the impeller body 11. A sleeve 12 is fixedly installed on both the first mounting rod 3 and the second mounting rod 16, and a mounting component is provided on the outer side of the sleeve 12.

[0027] In this example, the upper diameter of the second mounting rod 16 is consistent with the inner diameter of the mounting hole 4, ensuring that the two rods fit tightly and reducing shaking or loosening. A fixing bolt 17 is inserted into the left end of the lower end of the first mounting rod 3, and the fixing bolt 17 extends through the second mounting rod 16 to the right end of the first mounting rod 3, effectively preventing the rod from shifting or loosening during movement, and facilitating replacement or adjustment.

[0028] In this example, the fixing component includes a support plate 6. The support plate 6 is fixedly installed on the upper right end of the base 1. The plate body of the support plate 6 has a through groove 7. A threaded rod 8 is rotatably connected in the groove of the through groove 7. A push plate 9 is threadedly connected to the rod body of the threaded rod 8. By tightening the thread, it is stable and not easy to loosen, ensuring the reliability of the fixing.

[0029] In this example, a limiting rod 10 is fixedly installed on the left end of the push plate 9. The diameter of the limiting rod 10 is the same as the diameter of the fixing hole 5, and the fit is tight to ensure the accurate position of the push plate during movement, avoid deviation or shaking, improve the accuracy of operation, and the rod of the limiting rod 10 and the fixing hole 5 are set in an engaged state to form a stable mechanical connection, avoid loosening under vibration or load, and ensure stable operation of the equipment.

[0030] In this example, the mounting components include a support frame 13. The support frame 13 is fixedly mounted on both the left and right ends of the sleeve 12. A limit pin 14 is slidably connected to the frame of the support frame 13, and a spring 15 is sleeved and connected to the outside of the limit pin 14. The sliding connection and spring buffer design make installation and disassembly more convenient without the need for complicated adjustment tools or procedures.

[0031] In this example, the inner diameter of the impeller body 11 is the same as the outer diameter of the first mounting rod 3, and the outer diameter of the impeller body 11 is the same as the inner diameter of the sleeve 12. The matching of the inner and outer diameters can achieve a stable insertion and connection and reduce gaps.

[0032] In this example, the rod of the limiting pin 14 passes through the impeller body 11, and the rod of the limiting pin 14 is engaged with the first mounting rod 3. By engaging with the first mounting rod, the impeller can be effectively prevented from shifting or rotating during operation, ensuring that it is in the designated position.

[0033] During use, when the impeller is used to agitate minerals, a bearing 2 is fixedly installed on the outside of the base 1, and is connected to the bearing 2 through the mounting bracket or mounting plate on the flotation machine, ensuring the rotation of the base 1. A synchronous pulley or gear can also be installed on the outside of the base 1 to ensure the operation of the base 1 and the rotation of the impeller body 11. After the base 1 is installed, the impeller body 11 can be adjusted according to actual needs. Since the first mounting rod 3 is slidably connected inside the base 1, and the rod body of the limiting rod 10 is engaged with the fixing hole 5, it fixes the first mounting rod 3 and the base 1 together. When adjusting the immersion depth of the impeller body 11, the threaded rod 8 on the support plate 6 can be rotated, causing the threaded rod 8 to rotate within the groove 7. The threaded rod 8 is then connected to the push plate 9 through threads. When the threaded rod 8 rotates, it synchronously drives the push plate 9. The sliding within the groove 7 causes the push plate 9 to move synchronously with the limiting rod 10, thereby releasing the fixation between the first mounting rod 3 and the base 1. Then, the first mounting rod 3 can be pulled upward or pushed downward according to the actual situation, thereby adjusting the immersion depth of the impeller body 11 and adjusting the impeller body 11 to a suitable depth. After the depth of the impeller body 11 is adjusted, the threaded rod 8 can be rotated again, and the rotation of the threaded rod 8 causes the push plate 9 to slide within the groove 7, causing the push plate 9 to extend and retract the limiting rod 10. Since the fixing hole 5 is set in an array state with respect to the rod body of the first mounting rod 3, the extension and retraction of the limiting rod 10 engages with the fixing hole 5, thereby fixing the base 1 and the first mounting rod 3 together, fixing the position of the impeller body 11. By adjusting the impeller body 11, the air shear force can be precisely controlled, and it can adapt to diverse ore and process requirements.

[0034] When the impeller body 11 is in operation for a long time, it can be replaced or maintained. Since the rod of the limiting pin 14 passes through the impeller body 11 and engages with the rod of the first mounting rod 3, it can pull the limiting pin 14 to slide on the frame of the support frame 13. Simultaneously, the sliding of the limiting pin 14 compresses the spring 15, causing the limiting pin 14 to slide out of the impeller body 11 and the first mounting rod 3, thus releasing the fixation on the impeller body 11 and allowing for maintenance or replacement. Then, the inner diameter of the impeller body 11 is consistent with the outer diameter of the first mounting rod 3, and the outer diameter of the impeller body 11 is consistent with the outer diameter of the sleeve 12. The inner diameters are consistent, allowing the maintained or brand-new impeller body 11 to be fitted onto the rod of the first mounting rod 3. The impeller body 11 is then pushed upwards, placing it within the inner cavity of the sleeve 12. The pull on the limiting pin 14 is then released, and the limiting pin 14 is reset under the force of the spring 15. This causes the limiting pin 14 to eject through the impeller body 11 and engage with the rod of the first mounting rod 3, thus fixing the impeller body 11 to the first mounting rod 3 and the sleeve 12. The impeller body 11 can be quickly replaced by pulling the limiting pin 14, reducing downtime and simplifying the replacement process.

[0035] When the impeller body 11 is stirring the mineral, an installation hole 4 is opened at the bottom of the first mounting rod 3. Since the upper diameter of the second mounting rod 16 is the same as the inner diameter of the installation hole 4, the second mounting rod 16 can be inserted into the inner cavity of the installation hole 4. Then, the first mounting rod 3 and the second mounting rod 16 are fixed together by the fixing bolt 17. At the same time, a sleeve 12 is fixedly installed on the rod of the second mounting rod 16, and an installation component is provided on the outside of the sleeve 12, so that the impeller body 11 can be added again. By adding the second mounting rod 16 to the rod of the first mounting rod 3 and the impeller body 11 to the rod of the second mounting rod 16, the addition of the extra impeller body 11 can further improve the bubble dispersion and flow field distribution, thereby enhancing the flotation effect of the mineral.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
