Description

Technical Field

[0001] This utility model relates to the field of flotation machine impeller technology, and specifically to a flotation machine impeller wear-resistant device. Background Technology

[0002] Flotation machines are suitable for the separation of non-ferrous and ferrous metals, and can also be used for the separation of non-metallic minerals such as coal, fluorite, and talc. The flotation machine is driven by a motor with a delta drive, which rotates the impeller, generating centrifugal force to create negative pressure. This process draws in sufficient air to mix with the slurry, while simultaneously agitating the slurry and mixing it with reagents. At the same time, it refines the froth, causing minerals to adhere to the froth and float to the surface, forming mineralized froth. Adjusting the gate height controls the liquid level, allowing useful froth to be scraped off by scrapers.

[0003] Application number CN202222233787.9 discloses a wear-resistant flotation machine, including a tank body. A driving component is provided at the bottom of the tank body. From top to bottom, the tank body is equipped with a first guide cylinder, a metal dispersion cover, a stator, a wear-resistant impeller assembly, a fixed cylinder, and a flow passage cylinder in sequence with the rotor. The first and second guide cylinders are set to improve the flow of raw materials in the tank body. The second guide cylinder is located between each blade, so that the blades can work better with the second guide cylinder. The blade body is set as arc, so that the circumferential pressure on the blade when rotating with the shaft is reduced. In addition, a wear-resistant layer is provided on the blade, so that the blade has a better wear resistance and improves the service life of the overall flotation machine.

[0004] However, although the blades of the flotation machine are wear-resistant, they will inevitably wear out or even fail during long-term operation. In the existing structure, the blades and wear-resistant impeller assembly are usually integral or fixedly connected. When replacing the blades, it is necessary to disassemble multiple related components such as the stator, wear-resistant impeller assembly and even the first guide tube. This is not only complicated and time-consuming, but also increases the downtime for equipment maintenance, increases maintenance costs and labor intensity, and affects the continuity and production efficiency of mineral processing operations. Therefore, a wear-resistant device for flotation machine impellers is proposed. Utility Model Content

[0005] The main purpose of this invention is to provide a wear-resistant device for flotation machine impellers, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A wear-resistant device for a flotation machine impeller includes a rotating shaft and blades. The rotating shaft is rotatably installed inside the tank. A second slot is provided on the outer side of the rotating shaft. The second slot has multiple locations for inserting a second insert plate. The second insert plate is fixedly connected to one end of the blade. The blade has multiple blades. The top of the multiple blades is fixedly connected to a first insert plate, and a limiting plate is movably sleeved on the outer side of the rotating shaft. The bottom end of the limiting plate is provided with a first slot. The first slot is provided in multiple places, and the multiple first slots are used for the insertion of the first insert plate.

[0007] By adopting the above technical solution, the second slot on the rotating shaft cooperates with the second insert plate at one end of the blade, and the first slot on the limiting plate cooperates with the first insert plate at the top of the blade, thus realizing the rapid initial installation and positioning of the blade. Combined with the adjustable nut clamping limiting plate mechanism, it not only ensures the stability of the blade during high-speed operation and effectively prevents loosening and swaying, but also greatly simplifies the assembly process, improves the assembly accuracy and reliability of the overall structure, and makes blade maintenance and replacement convenient and efficient.

[0008] Specifically, a guide rod is installed through the inside of the limiting plate. There are multiple guide rods. The top ends of the multiple guide rods are fixedly connected to the bottom end of the connecting plate. The center of the top end of the connecting plate is connected to the end of the rotor. The center of the bottom end of the connecting plate is fixedly connected to the top end of the rotating shaft.

[0009] By adopting the above technical solution, the guide rod is installed inside the limiting plate and provides precise guidance for the up and down movement of the limiting plate, preventing it from deviating; the connecting plate is used to connect the rotor and the shaft, transmitting the rotor's torque to the shaft, thereby driving the blades to rotate; the overall structure remains stable during operation, ensuring the reliability of power transmission.

[0010] Specifically, nuts are fitted on the outer sides of the multiple guide rods, and the nuts are located between the connecting plate and the limiting plate. The nuts are adapted to the outer threads of the guide rods.

[0011] By adopting the above technical solution, the height position of the plate on the guide rod can be adjusted by rotating the nut; when the nut is tightened downwards, the limiting plate can be pressed downwards, thereby firmly fixing the first insert plate in the first slot and preventing the blade from loosening during operation.

[0012] Specifically, the bottom end of the guide rod is fixedly connected to the top end of the limiting block, and the limiting plate is located between the nut and the limiting block.

[0013] By adopting the above technical solution, the limiting block is used to prevent the limiting plate from accidentally falling off the bottom of the guide rod, forming a lower limit; together with the nut at the upper end, it forms a clamping and fixing structure for the limiting plate, ensuring that the limiting plate remains stable during equipment operation and will not move axially.

[0014] Specifically, a reinforcing plate is fixedly connected to the outer side of the rotating shaft. Multiple reinforcing plates are provided, and the sides of two adjacent reinforcing plates that are close to each other are attached to both sides of the blade.

[0015] By adopting the above technical solution, the reinforcing plates are tightly attached to both sides of the blade, providing additional support to the middle section of the blade, enhancing its bending and torsional strength, effectively reducing the vibration and deformation of the blade when it rotates at high speed or is subjected to uneven force, and extending the service life of the blade.

[0016] The beneficial effects of this utility model are: (1) The wear-resistant device for flotation machine impeller described in this utility model achieves rapid initial installation and positioning of the blade by cooperating with the second slot on the rotating shaft and the second insert plate at one end of the blade, and cooperating with the first slot on the limiting plate and the first insert plate at the top of the blade. Combined with the adjustable nut pressing the limiting plate mechanism, it not only ensures the stability of the blade during high-speed operation and effectively prevents loosening and swaying, but also greatly simplifies the assembly process, improves the assembly accuracy and reliability of the overall structure, and makes blade maintenance and replacement convenient and efficient.

[0017] (2) The wear-resistant device for the flotation machine impeller described in this utility model has reinforcing plates on both sides of the blades to provide additional support, effectively suppressing vibration and deformation, extending the service life of the blades, and improving the stability and production efficiency of the equipment during continuous operation.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As one embodiment of this utility model, such as Figures 1-5As shown, the wear-resistant device for a flotation machine impeller of this utility model includes a rotating shaft 4 and blades 6. The rotating shaft 4 is rotatably installed inside the tank body 8. A second slot 11 is provided on the outer side of the rotating shaft 4. There are multiple second slots 11 for a second insert plate 10 to be installed and inserted. The second insert plate 10 is fixedly connected to one end of the blade 6. The blade 6 has multiple blades. The top of the multiple blades 6 is fixedly connected to a first insert plate 9, and a limiting plate 5 is movably sleeved on the outer side of the rotating shaft 4. A first slot 12 is opened at the bottom of the limiting plate 5. The first slot 12 has multiple locations, and the multiple first slots 12 are used for the first insert plate 9 to be installed and inserted.

[0022] When using the blades, when installing the blades 6, the second insert plate 10 at one end of each blade 6 needs to be inserted into the multiple second slots 11 opened on the outside of the rotating shaft 4 to achieve the initial connection between the blades 6 and the rotating shaft 4; at the same time, the first insert plates 9 at the top of the multiple blades 6 are inserted into the multiple first slots 12 opened at the bottom of the limiting plate 5 to complete the initial fixation of the blades 6 through the double insertion structure, preparing for further reinforcement in the future.

[0023] This utility model also includes a guide rod 2 installed through the inside of the limiting plate 5. There are multiple guide rods 2. The top ends of the multiple guide rods 2 are fixedly connected to the bottom end of the connecting plate 1. The center of the top end of the connecting plate 1 is connected to the end of the rotor. The center of the bottom end of the connecting plate 1 is fixedly connected to the top end of the rotating shaft 4.

[0024] During use, the guide rod 2 is installed inside the limiting plate 5 and provides precise guidance for the up and down movement of the limiting plate 5 to prevent it from tilting; the connecting plate 1 is used to connect the rotor and the rotating shaft 4, and transmit the torque of the rotor to the rotating shaft 4, thereby driving the blade 6 to rotate; the overall structure remains stable during operation to ensure the reliability of power transmission.

[0025] This utility model also includes a nut 3 sleeved on the outer side of the multiple guide rods 2, the nut 3 being located between the connecting plate 1 and the limiting plate 5, and the nut 3 being threadedly adapted to the outer side of the guide rod 2.

[0026] During use, the height position of the nut 3 on the guide rod 2 can be adjusted by rotating the nut 3; when the nut 3 is tightened downwards, the limiting plate 5 can be pressed downwards, thereby firmly fixing the first insert plate 9 in the first slot 12 and preventing the blade 6 from loosening during operation.

[0027] The present invention also includes that the bottom end of the guide rod 2 is fixedly connected to the top end of the limiting block 13, and the limiting plate 5 is disposed between the nut 3 and the limiting block 13.

[0028] When in use, the limiting block 13 is used to prevent the limiting plate 5 from accidentally falling off the bottom of the guide rod 2, forming a lower limit; together with the nut 3 at the upper end, it forms a clamping and fixing structure for the limiting plate 5, ensuring that the limiting plate 5 remains stable during equipment operation and will not move axially.

[0029] The present invention also includes a reinforcing plate 7 fixedly connected to the outer side of the rotating shaft 4. The reinforcing plate 7 is provided in multiple pieces, and the side of two adjacent reinforcing plates 7 that are close to each other is attached to both sides of the blade 6.

[0030] When in use, the reinforcing plates 7 are tightly attached to both sides of the blade 6, providing additional support to the middle section of the blade 6, enhancing its bending and torsional strength, effectively reducing the vibration and deformation of the blade 6 when it rotates at high speed or is subjected to uneven force, and extending the service life of the blade 6.

[0031] In use, the blade 6 is installed and fixed through a double-interlocking structure. Multiple blades 6 are provided, and one end of each blade 6 is fixedly connected to a second insert plate 10. The second insert plate 10 is inserted into multiple second slots 11 on the outer side of the rotating shaft 4. Simultaneously, the top ends of multiple blades 6 are fixedly connected to first insert plates 9, which are inserted into multiple first slots 12 at the bottom of the limiting plate 5. To ensure the stability of the limiting plate 5 in limiting the first insert plate 9, after the first insert plate 9 is inserted into the first slot 12, the nut 3 is tightened downwards to clamp the limiting plate 5 with the limiting block 13, thus fixing the limiting plate 5. The limiting block 13 also prevents the limiting plate 5 from falling off the bottom of the guide rod 2, further ensuring the installation stability of the limiting plate 5. Furthermore, during installation... The two adjacent reinforcing plates 7 can be attached to both sides of the blade 6 to reinforce and support the blade 6, reducing the shaking of the blade 6 during rotation. When the blade 6 wears out or even fails after long-term operation and needs to be replaced, simply loosen the nut 3, move the limiting plate 5 upward along the guide rod 2 to disengage the first insert plate 9 from the first slot 12, and then pull out the second insert plate 10 at one end of the blade 6 from the second slot 11 of the rotating shaft 4. The worn blade 6 can then be removed and replaced individually without disassembling multiple related components such as the stator, wear-resistant impeller assembly, or even the first guide tube. After replacement, the blade 6 can be replaced again using the same operation. This effectively simplifies the operation process, shortens equipment downtime for maintenance, reduces maintenance costs and labor intensity, and ensures the continuity and production efficiency of mineral processing operations.
