Description

Technical Field

[0001] The invention belongs to the technical field of iron ore powder concentrating equipment, and in particular relates to a tailings recovery machine. Background Art

[0002] Tailings recovery machines have been widely used in many fields such as metallurgy, mining, water conservancy, hydropower, sand and gravel plants, glass plants, coal preparation plants, etc. Especially in the iron ore dressing process, tailings recovery machines can effectively recover the effective components in the tailings, improve resource utilization and reduce resource waste.

[0003] However, in actual application, the design of traditional tailings machine recovery boxes often sets the bottom wall of the recovery box and the discharge port as a static connection. This design method can easily lead to incomplete discharge of iron powder, and some iron powder will remain in the recovery box, which not only reduces the recovery efficiency and causes waste of resources, but may also cause blockage of the discharge port, because the static bottom structure is not conducive to the smooth outflow of iron powder, which increases the difficulty and complexity of discharge. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a tailings recovery machine that can overcome the above problems or at least partially solve the above problems.

[0005] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a tailings recovery machine comprises a frame and a rotating rod rotatably arranged on the frame, wherein a plurality of magnetic disks equidistantly distributed and rotating inside the frame are fixedly connected to the rotating rod, and an inclined scraper fixedly connected to the frame is adhered between two adjacent magnetic disks, and a discharging chute is provided on the inclined scraper, and a flushing member parallel to the discharging chute is provided at the rear end of the discharging chute, a recovery box corresponding to the front end of the discharging chute is provided on the frame, and also includes a discharge port opened on the recovery box, and a guide plate that can move back and forth up and down is provided between the inner wall of the recovery box and the discharge port, and when the guide plate contacts the top wall of the discharge port, the discharge port is in a closed state, and when the guide plate contacts the bottom wall of the discharge port, the discharge port is in an open state.

[0006] Preferably, the flushing member comprises a horizontal tube fixed on the inner wall of the U-shaped groove at the top of the frame, one end of the horizontal tube is sealed, the other end of the horizontal tube is open for water inlet, and the horizontal tube is connected to an inclined branch pipe corresponding to the rear end of each discharge trough.

[0007] Preferably, a plurality of connecting plates are fixedly connected between the recovery box and the frame, and the top opening of the recovery box is located below the front end of the inclined scraper.

[0008] Preferably, the bottom of the guide plate and the bottom wall of the discharge port are both horizontally arranged, and the top of the guide plate and the top of the discharge port are both inclined.

[0009] Preferably, a driving unit is installed on the recycling box, and the output end of the driving unit is connected to a connecting shaft rotatably arranged between the inner walls of the recycling box, a plurality of toggle members are fixedly connected to the connecting shaft, and a semicircular interference block linked to the toggle member is fixedly connected to the bottom of the guide plate.

[0010] Preferably, the toggle member comprises a circular block fixedly connected to the connecting shaft and in contact with the surface of the semicircular abutment block, and a plurality of arc-shaped toggle plates distributed in a circumference are fixedly connected to the circular block.

[0011] Preferably, the bottom of the recycling box is fixedly connected to a support plate, the top of the support plate is fixedly connected to a limit box, a cavity is provided in the limit box, the inner wall of the cavity is slidably connected to a movable plate, the top of the movable plate is fixedly connected to a plurality of support rods, one end of the support rod passes through the top of the limit box and is fixedly connected to the bottom of the material guide plate, and a spring is sleeved on the support rod and fixedly connected between the top of the movable plate and the top wall of the cavity.

[0012] Preferably, a pair of air guide tubes are connected to the limit box, and an air blowing plate is connected between one end of the two air guide tubes that pass through the outside of the recovery box, and the air blowing plate corresponds to the top of the recovery box.

[0013] Preferably, a vertical plate is fixedly connected to the blowing plate, and the vertical plate is fixedly connected to the top of the recovery box.

[0014] Preferably, the vertical plate is located in front of the inclined scraper, and the top of the vertical plate is higher than the front end of the inclined scraper.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention designs the guide plate between the recovery box and the discharge port to reciprocate up and down, so as to periodically change the position of the guide plate, effectively breaking the static state of the iron powder on the surface of the guide plate. When the guide plate moves upward, the iron powder on the surface of the guide plate will be subjected to an upward force, which not only helps to separate the iron powder from the surface of the guide plate, but also pushes the iron powder to move toward the discharge port. Subsequently, in the process of the guide plate moving downward, the iron powder will continue to slide toward the discharge port under the action of gravity. This up and down reciprocating motion mode makes the movement of the iron powder on the guide plate easier and smoother. Secondly, the up and down reciprocating movement of the guide plate also plays a role in reducing the friction between the iron powders. In a static state, the iron powders may generate a large friction due to mutual contact, resulting in poor flow or accumulation of iron powders. The up and down shaking of the guide plate can continuously disturb the iron powders, thereby reducing the contact area and friction between the iron powders, and further promoting the flow of iron powders. In addition, the up and down reciprocating movement of the guide plate can also help avoid the problem of incomplete discharge of iron powder and blockage of the discharge port due to accumulation. In the traditional fixed guide plate design, iron powder may accumulate on the guide plate, causing blockage of the discharge port and affecting the recovery efficiency. The up and down reciprocating movement of the guide plate can continuously push the accumulated iron powder to the discharge port, ensuring the continuous and stable discharge of iron powder. Finally, the up and down reciprocating movement of the guide plate is also combined with the design of the blowing plate to further improve the recycling efficiency. When the guide plate moves upward, it will compress the gas in the cavity and send the gas into the blowing plate through the air guide pipe. The gas released by the blowing plate will blow directly downward to the inner wall of the recycling box, blowing down the iron powder that is sputtered and attached to the inner wall. This design not only reduces the adhesion of iron powder on the inner wall of the recycling box, but also allows the iron powder to flow more smoothly to the discharge port, thereby improving the efficiency and effect of the entire recycling process.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0019] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0020] In the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] Reference Figure 1-Figure 8 The tailings recovery machine includes a frame 1 and a rotating rod 2 rotatably arranged on the frame 1, a plurality of magnetic disks 3 which are equidistantly distributed and rotate inside the frame 1 are fixedly connected to the rotating rod 2, an inclined scraper 4 fixedly connected to the frame 1 is fitted between two adjacent magnetic disks 3, a discharging chute 41 is provided on the inclined scraper 4, a flushing member 5 which is parallel to the discharging chute 41 is provided at the rear end of the discharging chute 41, a recovery box 6 corresponding to the front end of the discharging chute 41 is provided on the frame 1, and also includes a discharge port 61 opened on the recovery box 6, a guide plate 62 which can reciprocate up and down is provided between the inner wall of the recovery box 6 and the discharge port 61, when the guide plate 62 contacts the top wall of the discharge port 61, the discharge port 61 is in a closed state, and when the guide plate 62 contacts the bottom wall of the discharge port 61, the discharge port 61 is in an open state.

[0022] In the above technical scheme, since one end of the rotating rod 2 is connected to the output end of the reduction motor installed on the frame 1, when the reduction motor is started, it will drive the rotating rod 2 to rotate, and then drive the multiple magnetic disks 3 fixed on the rotating rod 2 to rotate inside the frame 1, so as to absorb the iron powder in the material flowing through the bottom wall of the frame 1. At the same time, the inclined scraper 4 is fitted between every two adjacent magnetic disks 3. When the magnetic disk 3 rotates and passes through the inclined scraper 4, the iron powder absorbed on the surface of the magnetic disk 3 will be automatically scraped into the discharge chute 41 below under the action of the inclined scraper 4. In order to further enhance the cleaning effect of the iron powder in the discharge chute 41, the flushing member 5 will spray water into the discharge chute 41, flush the scraped iron powder to the top port of the recovery box 6, and finally fall on the surface of the guide plate 62. In this technical scheme, the guide plate 62 adopts An up and down reciprocating motion design is used. This design allows the guide plate 62 to produce a vibration effect during the up and down shaking process, effectively breaking the static state of the iron powder on the surface of the guide plate 62. Specifically, when the guide plate 62 shakes up and down, the iron powder on the surface of the guide plate 62 will be subjected to periodic impact force. This impact force not only helps to separate the iron powder from the surface of the guide plate 62, but also pushes the iron powder to move toward the discharge port 61, making the movement of the iron powder on the guide plate 62 easier and smoother. This design avoids the problem of incomplete discharge of iron powder on the surface of the guide plate 62 and blockage of the discharge port 61 due to accumulation. At the same time, the up and down vibration of the guide plate 62 can also reduce the friction between the iron powders, further promote the flow of iron powder, and ensure that the iron powder can flow to the discharge port 61 continuously and stably.

[0023] Reference Figure 1 and Figure 2 Furthermore, the flushing member 5 includes a horizontal tube 51 fixed on the inner wall of the U-shaped groove at the top of the frame 1, one end of the horizontal tube 51 is sealed, and the other end of the horizontal tube 51 is open for water inlet. The horizontal tube 51 is connected with an inclined branch pipe 52 corresponding to the rear end of each discharge trough 41. In actual use, it is only necessary to connect the open end of the horizontal tube 51 to an external water supply mechanism, and then start the external water supply mechanism. The water flow will be drawn into the horizontal tube 51 and flow along the pipeline to each inclined branch pipe 52, so that the water flow ejected from the inclined branch pipe 52 will flush the iron powder scraped off in the discharge trough 41, so as to further remove the iron powder scraped off in the discharge trough 41 and flow smoothly into the recovery box 6.

[0024] Reference Figure 4 A plurality of connecting plates 63 are fixedly connected between the recovery box 6 and the frame 1. The top opening of the recovery box 6 is located below the front end of the inclined scraper 4. The connecting plates 63 are designed to stably limit the recovery box 6 below the front end of the inclined scraper 4, so that the iron powder falling from the discharge chute 41 in the inclined scraper 4 can be smoothly collected by falling from the top port of the recovery box 6.

[0025] In addition, it should be noted that the shape of the discharge chute 41 can be U-shaped or V-shaped. The U-shaped discharge chute 41 has a relatively flat bottom and can provide a relatively wide collection area. It is suitable for scenarios where the iron powder flow rate is large or requires continuous collection for a long time. This design can ensure that the iron powder will not accumulate or clog due to excessive concentration during the scraping process, thereby ensuring the continuity and stability of the collection process. The V-shaped discharge chute 41 is characterized by its sharp bottom and narrow collection port, and is suitable for scenarios with a small iron powder flow rate. The V-shaped design can more effectively guide the iron powder to concentrate to the top port of the recovery box 6, reduce the scattering and waste of iron powder, and also help to improve the collection efficiency. Therefore, the shape of the discharge chute 41 can be selected according to actual usage.

[0026] Reference Figure 5 and Figure 6 Furthermore, the bottom of the guide plate 62 and the bottom wall of the discharge port 61 are both horizontally arranged, the top of the guide plate 62 and the top of the discharge port 61 are both inclined, and a driving unit 64 is installed on the recovery box 6, and the output end of the driving unit 64 is connected to a connecting shaft 65 rotatably arranged between the inner walls of the recovery box 6, and a plurality of toggles are fixedly connected to the connecting shaft 65. A semicircular abutment block 66 linked to the toggling member is fixedly connected to the bottom of the guide plate 62, and the toggling member includes a circular block 67 fixedly connected to the connecting shaft 65 and in contact with the surface of the semicircular abutment block 66, and a circular block 67 is fixedly connected to the connecting shaft 65. A plurality of arc-shaped shifting plates 68 distributed in a circle are fixedly connected thereto, a support plate 69 is fixedly connected to the bottom of the recovery box 6, a limit box 610 is fixedly connected to the top of the support plate 69, a cavity 611 is provided in the limit box 610, a movable plate 612 is slidably connected to the inner wall of the cavity 611, a plurality of support rods 613 are fixedly connected to the top of the movable plate 612, one end of the support rod 613 passes through the top of the limit box 610 and is fixedly connected to the bottom of the guide plate 62, a spring 614 is sleeved on the support rod 613 and fixedly connected between the top of the movable plate 612 and the top wall of the cavity 611.

[0027] When the guide plate 62 in the above technical solution realizes the up and down reciprocating motion, it starts the driving part 64 using the servo motor to drive the multiple circular blocks 67 on the connecting shaft 65 to rotate together. When the arc-shaped paddle plate 68 fixed on the surface of the circular block 67 abuts against the bottom of the semicircular abutment block 66, the semicircular abutment block 66 will be subjected to an upward abutment force, and drive the support rod 613 connected to the bottom of the guide plate 62 to cooperate with the moving plate 612 to slide along the inner wall of the cavity 611 to squeeze the spring 614, and at the same time push the guide plate 62 to slide upward along the inner wall between the recovery box 6 and the discharge port 61 to abut against the top wall of the discharge port 61. When the connecting shaft 65 continues to drive the circular block 67 to rotate, the arc-shaped paddle plate 68 breaks away from the bottom of the semicircular abutment block 66, and the semicircular The resistance block 66 resists against the surface of the circular block 67. At this time, the guide plate 62 will slide downward along the inner wall between the recovery box 6 and the discharge port 61 and resist against the bottom wall of the discharge port 61 under the elastic reset of the spring 614. Through this up and down reciprocating design, the guide plate 62 can continuously change its position, which helps to separate the iron powder attached to its surface and further push the iron powder to move toward the discharge port 61. This makes the movement of the iron powder on the guide plate 62 easier and smoother, effectively avoiding the problem of incomplete discharge of iron powder and blockage of the discharge port 61 due to accumulation. At the same time, this design can also reduce the friction between the iron powders, further promote the flow of iron powder, and ensure that the iron powder can flow to the discharge port 61 continuously and stably.

[0028] It should be noted that there are three arc-shaped paddles 68 connected to the surface of the circular block 67, so that the circular block 67 cooperates with multiple arc-shaped paddles 68 to periodically rotate along the surface of the semicircular resistance block 66. Compared with the design of using only one arc-shaped paddle plate 68, the three arc-shaped paddle plates 68 can come into contact with the semicircular resistance block 66 more frequently, thereby shortening the interval time of each paddle movement, and making the periodic vibration of the guide plate 62 more frequent. The frequent vibration helps to more effectively separate the iron powder attached to the surface of the guide plate 62 and push the iron powder to flow to the discharge port 61 faster, which not only improves the discharge efficiency of the iron powder, but also further reduces the accumulation and retention of iron powder on the guide plate 62, and reduces the risk of blockage of the discharge port 61.

[0029] Reference Figure 4-Figure 8 Furthermore, a pair of air guide tubes 615 are connected to the limit box 610, and an air blowing plate 616 is connected between one end of the two air guide tubes 615 that pass through the outside of the recovery box 6. The air blowing plate 616 corresponds to the top of the recovery box 6, and a vertical plate 617 is fixedly connected to the air blowing plate 616. The vertical plate 617 is fixedly connected to the top of the recovery box 6, and the vertical plate 617 is located in front of the inclined scraper 4. The top of the vertical plate 617 is higher than the front end of the inclined scraper 4.

[0030] Such a technical solution is adopted considering that the iron powder washed by the front end of the inclined scraper 4 may splash onto the inner wall of the recovery box 6 corresponding to the front end of the inclined scraper 4. Based on this problem, when the guide plate 62 moves upward, the support rod 613 will pull the movable plate 612 to slide along the inner wall of the cavity 611, and the gas in the cavity 611 will be compressed into the blowing plate 616 connected to one end of the air guide pipe 615. Moreover, the blowing plate 616 is fixed above the recovery box 6 by the vertical plate 617. When the gas is released from the nozzle at the bottom of the blowing plate 616, it will blow straight downward to the inner wall of the recovery box 6 on the side corresponding to the discharge port 61. Such a design can ensure that the iron powder splashed and attached to the inner wall is blown by the gas, so that it can fall off the wall more easily. In this way, not only can the adhesion of iron powder to the inner wall of the recovery box 6 be effectively reduced, but also the efficiency and effect of the entire recycling process can be improved.

[0031] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of them belong to the protection scope of the present invention.
