Description

Technical Field

[0001] This utility model relates to the field of flotation equipment technology, and in particular to a mineral processing device. Background Technology

[0002] Flotation equipment is a commonly used technique in mineral processing. The efficiency of flotation equipment affects the overall mineral processing efficiency. Therefore, improving the efficiency of flotation equipment is of great significance to the mineral processing output of the entire process.

[0003] Flotation equipment utilizes the fact that target mineral particles adhere to froth, and the froth is scraped off by a scraper and enters a collection hopper to achieve the purpose of mineral beneficiation. However, since the froth needs to be discharged through a pipe after entering the collection hopper, and because the froth has poor fluidity and descends slowly, the discharge speed is slow. When the froth accumulates in the collection hopper, it is not conducive to feeding, thus affecting the mineral beneficiation speed.

[0004] Based on the above problems, Chinese utility model patent application number 2024225905384 discloses a tailings recovery pyrite separation and beneficiation device. It uses a rotating shaft driven by a scraper to drive an anti-clogging structure to float up and down. When floating up and down, the pressure plate 507 squeezes the foam downward, thereby increasing the foam discharge speed and solving the foam accumulation problem. However, it uses a fan-shaped toothed disc and rack to drive the pressure plate. In this driving method, the toothed disc and rack will have a separation and engagement process. During the separation and engagement process, there is impact wear between the teeth, resulting in a large amount of wear. Moreover, when the two separate, the pressure plate rebounds quickly under the action of spring force, which generates a rapid upward disturbance to the foam, resulting in poor downward pressure on the foam.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] Please refer to Figure 1-6 As a specific implementation method, the technical solution of this utility model is: a mineral processing device, including a collecting hopper 6, a rotating shaft 402, and multiple pressing plates 507, and further including:

[0029] Rigid rods 70, including at least two, are vertically guided and disposed on the collection hopper 6. The two rigid rods 70 are spaced apart along the length direction of the rotating shaft 402. The pressing plate 507 is disposed on the two rigid rods 70.

[0030] The transmission assembly 7 includes a third drive wheel 75 rotatably disposed on the outer side wall of the collection hopper 6. An eccentric shaft 76 is eccentrically disposed on the third drive wheel 75. A transmission rod 77 is rotatably connected to the eccentric shaft 76. The other end of the transmission rod 77 is pulsatorically connected to at least two rigid rods 70. The third drive wheel 75 is pulsatorically connected to the rotating shaft 402. The axes of the eccentric shaft 76 and the drive wheel are both parallel to the rotating shaft 402.

[0031] Specifically, it should be noted that, similar to the prior art, this application includes a flotation machine body, a rotating shaft 402 rotatably mounted on the flotation machine body, the rotating shaft 402 being driven by a motor, and a scraper mounted on the rotating shaft 402. In one specific embodiment, it includes a collection hopper 6, with an L-shaped base 61 positioned below the collection hopper, thus creating a certain distance between the bottom surface of the collection hopper and the lower bottom surface, facilitating the vertical movement of the rigid rods 70. Three rigid rods 70 are vertically guided at the bottom of the collection hopper 6, and a pressing plate 507 is positioned at the upper end of the three rigid rods 70. A transmission assembly 7 is positioned between the rotating shaft 402 and the rigid rods 70, and the transmission assembly 7 includes components related to... The rotating shaft 402 drives the third drive wheel 75, which is equipped with an eccentric shaft 76. The eccentric wheel and three rigid rods 70 are driven to rotate. When the rotating shaft 402 is driven to rotate, it drives the third drive wheel 75 to rotate around its axis. At this time, it drives the eccentric shaft 76 to rotate around the axis of the third drive wheel 75. Thus, the eccentric shaft 76 drives the transmission rod 77 to drive the three rigid rods 70 to reciprocate in the vertical direction, thereby driving the tablet 507 to move vertically. With this transmission method, the phenomenon of the tablet 507 rising rapidly will not occur as in the prior art, reducing the disturbance to the foam caused by the rapid rise of the tablet 507 and improving the pressing effect of the tablet 507 on the foam.

[0032] Furthermore, as a preferred embodiment, the transmission assembly 7 includes two components, which are respectively disposed at both ends of the collection hopper 6 along the axial direction of the rotating shaft 402. Specifically, by providing a transmission assembly 7 at each end of the collection hopper 6, the two transmission assemblies 7 simultaneously drive the three rigid rods 70 up and down synchronously on both sides, thereby achieving a better driving effect.

[0033] Furthermore, as a specific implementation method, refer to Figures 1-4 , Figures 7-9 The rigid rod 70 is guided and disposed at the bottom of the collection hopper 6. The lower ends of at least two rigid rods 70 are connected to a rigid base plate 79, and the ends of the base plate 79 are connected to a transmission member 78. The transmission member 78 is rotatably connected to the end of the transmission rod 77.

[0034] Specifically, the base plate 79 is a rigid plate made of metal. The lower ends of the three rigid rods 70 are all connected to the base plate 79. Two transmission components 78 are coaxially arranged at both ends of the base plate 79. Specifically, the transmission component 78 is a columnar component that is fixedly connected to the base plate 79. One end of the transmission rod 77 is connected to the eccentric shaft 76, and the other end is connected to the transmission component 78. When the third drive wheel 75 rotates around the axis, the transmission component 78 is driven to move up and down through the eccentric rod and the transmission rod 77, thereby driving the base plate 79 and the rigid rods 70 to move up and down, achieving the driving effect.

[0035] Furthermore, as a specific implementation method, refer to Figure 5 , Figure 8 Both ends of the transmission rod 77 are provided with bushings 770, and the axes of the two bushings 770 are arranged parallel. One bushing 770 is sleeved with the eccentric shaft 76, and the other bushing 770 is sleeved with the transmission component 78. Specifically, the transmission rod 77 is rigidly set, with bushings 770 connected to both ends. The bushings 770 are rotatably sleeved with the eccentric shaft 76 and the transmission component 78, thereby driving the base plate 79 to move up and down.

[0036] Furthermore, the transmission component 78 is detachably and fixedly connected to the base plate 79. Specifically, refer to... Figure 8 The transmission component 78 is provided with a flange at its end, and a second flange adapted to the flange is welded to the end of the base plate 79. The flange and the second flange can be locked and fixed by screws, thereby realizing the detachable fixed connection between the base plate 79 and the drive component. The detachable fixed connection facilitates the disassembly and installation of the transmission component 78 and facilitates later maintenance.

[0037] Furthermore, as a specific implementation method, refer to Figures 2-6 The transmission assembly 7 further includes a first drive wheel 71 disposed on the rotating shaft 402, and the first drive wheel 71 and the third drive wheel 75 are driven by a belt. Specifically, the first drive wheel 71 can be sleeved onto the end of the rotating shaft 402 and driven by a key. When two transmission components 7 are provided, the two first drive wheels 71 are respectively located at both ends of the rotating shaft 402. A second drive wheel 73 is also provided on the side wall of the flotation machine body. In a specific embodiment, the first drive wheel 71, the second drive wheel 73 and the third drive wheel 75 are all pulleys. The second drive wheel 73 is a double groove pulley. The first drive wheel 71 and the second drive wheel 73 are driven and connected by a first transmission belt 72. The second drive wheel 73 and the third drive wheel 75 are driven and connected by a second transmission belt 74 to achieve the transmission purpose. The second drive wheel 73 is rotatably engaged with a second shaft 730, which is detachably fixed to the side wall of the flotation machine body. The third drive wheel 75 is rotatably engaged with a third shaft 750, which is fixedly connected to the side wall of the collection hopper 6.

[0038] Specifically, it should be noted that when two transmission components 7 are provided, both first drive wheels 71 are located at both ends of the rotating shaft 402. One first drive wheel 71 is a single-groove pulley, and the other first drive wheel 71 is a double-groove pulley. One groove of the double-groove pulley is provided with the first transmission belt 72, and the other groove is provided with the third transmission belt connected to the drive motor. The output shaft of the drive motor is located on the pulley connected to the third transmission belt, so that the rotating shaft 402 can be driven by the drive motor and the third transmission belt. The first transmission belt 72, the second transmission belt 74, and the third transmission belt are triangular transmission belts. The transmission method of using transmission belts to drive the drive motor and the rotating shaft 402 is a common transmission method in the prior art. To save space and avoid redundancy, the specific structural details here will not be shown one by one, and those skilled in the art should understand.

[0039] Furthermore, as a specific implementation method, refer to Figure 9 The upper end of the rigid rod 70 is integrally provided with a support plate 701, which extends along an axis perpendicular to the rotating shaft 402. The lower end of the rigid rod 70 is detachably and fixedly connected to the base plate 79, and the pressure plate 507 is connected to the support plate 701. Specifically, this arrangement facilitates the disassembly and installation of the rigid rod 70 and facilitates later maintenance.

[0040] Furthermore, a threaded rod 703 is coaxially provided at the lower end of the rigid rod 70, and a through hole 790 is provided on the base plate 79 for the threaded rod 703 to pass through. The lower end of the threaded rod 703 passing through the through hole 790 is threadedly connected to a limit nut 702. The radial dimension of the threaded rod 703 is smaller than the radial dimension of the rigid rod 70.

[0041] For details, please refer to Figure 9 The rigid rod 70 is a cylindrical metal rod. A guide hole 602 is provided at the bottom of the collecting hopper 6 for guiding the rigid rod 70 to slide and seal. The sealing method adopts a commonly used method in the art, which will not be described in detail here. A stepped shaft is provided at the lower end of the rigid rod 70. The outer surface of the stepped shaft is threaded to form a threaded rod 703. The threaded rod 703 can pass through the through hole 790 on the bottom plate 79. The lower end is threadedly connected to the limiting nut 702, thereby connecting the rigid rod 70 to the bottom plate 79.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
