Description

Technical Field

[0001] The utility model relates to the technical field of tailings treatment, in particular to a device for reselecting tailings. Background Technique

[0002] In ore dressing, the part with a low content of useful target components in the products of the separation operation and unable to be used for production is called tailings. According to the different components of the ore contained in the tailings, various methods can be used for reselecting the tailings in the prior art.

[0003] The prior art can refer to the Chinese patent with the authorization announcement number CN210787638U, which discloses an environmental protection tailings treatment device, including a feed hopper, a servo motor, a rotating shaft, a crushing drum, crushing cutter heads, a vibrator, a vibrating shaft, a vibrating screen plate, a metal collection plate and a discharge bin. The waste tailings are added into the treatment box from the feed hopper, the servo motor is started to work, the rotating shaft drives the crushing drum to rotate, after the crushing cutter heads on the crushing drum rotate at high speed, the tailings are crushed one by one and fall on the vibrating screen plate. After the vibrator is started to work, the vibrating shaft will make the vibrating screen plate vibrate, and the crushed tailings will be vibrated and screened down. The tailings with a high metal content will be attracted by the metal collection plate, that is, the non-metal tailings will fall into the discharge bin for unified collection and treatment, so as to separate the metal tailings from the non-metal tailings and facilitate the recycling of the metal tailings.

[0004] However, the crushing cutter heads in the above environmental protection tailings treatment device may become blunt after long-term use, thus reducing the crushing effect on the tailings. When the tailings with larger particle sizes fall on the vibrating screen plate, the vibrating screen plate cannot screen them down, resulting in the accumulation of the tailings with larger particle sizes on the surface of the vibrating screen plate, and further making it inconvenient for the vibrating screen plate to work. Content of the Utility Model

When the second sliding plate abuts against the vibrating screen plate, the driving member drives the first sliding plate and the second sliding plate to move together in the direction close to the door panel, so that it is convenient to drive the tailings with larger particle size accumulated on the vibrating screen plate to move into the collection box, and then the vibrating screen plate can be operated.

[0009] Preferably, the driving component includes a mounting plate, the mounting plate is fixedly connected to the side wall of the processing box, the mounting plate is mounted on a motor, the output end of the motor is transmission-connected to a second rotating rod, two first driving ropes are wound on the second rotating rod, one end of the first driving rope is fixedly connected to the outer side wall of the second rotating rod, the other end of the first driving rope is fixedly connected to the side wall of the second sliding plate close to the door panel, a second driving rope is wound on the second rotating rod, one end of the second driving rope is fixedly connected to the outer side wall of the second rotating rod, the other end of the second driving rope is fixedly connected to the side wall of the second sliding plate through the first sliding plate, the first driving rope and the second driving rope are wound around the outer side wall of the second rotating rod in opposite directions, and a guide member for guiding the first sliding plate is provided on the inner wall of the processing box.

[0010] By adopting the above technical solution, when it is necessary to drive the first sliding plate and the second sliding plate to move towards the door panel, the motor is first started. The output end of the motor drives the second rotating rod to rotate. The second rotating rod tightens the first driving rope and simultaneously loosens the second driving rope, thereby facilitating the driving of the first sliding plate and the second sliding plate to move. At the same time, under the guiding action of the guiding member, it is convenient to drive the first sliding plate and the second sliding plate to move linearly.

[0015] Preferably, the limiting member includes a ratchet wheel. The ratchet wheel is fixedly connected to one end of the first rotating rod. A third rotating rod is rotatably arranged on the side wall of the processing box. A ratchet tooth is fixedly sleeved on the outer side wall of the third rotating rod. The ratchet tooth is matched with the ratchet wheel. A torsion spring is sleeved on the outer side wall of the third rotating rod. One end of the torsion spring is fixedly connected to the side wall of the processing box, and the other end of the torsion spring is fixedly connected to the side wall of the ratchet tooth.

When the ratchet tooth is separated from the ratchet wheel, the limiting effect of the ratchet tooth on the ratchet wheel can be easily released, and then the limiting effect on the first rotating rod can be easily released. Then, the operator manually drives the door panel to rotate. When the door panel rotates by a certain angle, the operator releases the first handle.

[0018] By adopting the above technical solution, when it is necessary to drive the second sliding plate to abut against the vibrating sieve plate, due to the setting of the inclined surface, the possibility of tailings being stuck between the second sliding plate and the vibrating sieve plate can be easily reduced, so as to facilitate driving the tailings on the vibrating sieve plate to move.

[0019] Preferably, a relief groove is formed in the inner wall of the through groove, and the door panel can be inserted into the inner wall of the relief groove.

[0020] By adopting the above technical solution, when it is necessary to drive the door panel to rotate, due to the setting of the relief groove, the door panel can be easily rotated into the relief groove, so as to facilitate storing the door panel.

[0021] Preferably, a second handle is fixedly connected to one end of the first rotating rod.

[0025] 2. When it is necessary to drive the first sliding plate and the second sliding plate to move towards the door panel, start the motor first. The output end of the motor drives the second rotating rod to rotate.

The cross-section of the through groove 14 is square and extends along the length direction of the processing box 1. A first rotating rod 15 is rotatably arranged on the inner wall of the through groove 14 through a bearing. The cross-section of the first rotating rod 15 is circular and is arranged along the width direction of the processing box 1. A door plate 16 is sleeved and fixed on the outer side wall of the first rotating rod 15. The door plate 16 can abut against the inner wall of the through groove 14. A limiting member 5 for limiting the first rotating rod 15 is arranged on the side wall of the processing box 1. A collecting box 17 is fixedly connected to the side wall of the processing box 1 close to the door plate 16. The cross-section of the collecting box 17 is concave and is arranged along the length direction of the processing box 1.

[0036] When it is necessary to clean the tailings on the vibrating sieve plate 11, first release the limiting effect of the limiting member 5 on the first rotating rod 15, and then manually drive the door plate 16 to rotate by an operator. When the door plate 16 rotates by a certain angle, limit the first rotating rod 15 through the limiting member 5, so as to facilitate the limiting of the door plate 16. Then drive the second sliding plate 13 to move vertically downward through the driving member 4. When the second sliding plate 13 abuts against the vibrating sieve plate 11, drive the first sliding plate 12 and the second sliding plate 13 to move together in the direction close to the door plate 16 through the driving component 2, so as to facilitate driving the tailings with larger particle sizes accumulated on the vibrating sieve plate 11 to move into the collecting box 17, and further facilitate the work of the vibrating sieve plate 11.

[0037] As Figure 1 and Figure 2As shown in the figure, the driving component 2 includes a mounting plate 21. The cross-section of the mounting plate 21 is L-shaped and is arranged along the length direction of the processing box 1.

The cross-section of the second rotating rod 23 is circular and is arranged along the width direction of the processing box 1. Two first driving ropes 24 are wound around the second rotating rod 23. One end of the first driving rope 24 is fixedly connected to the outer side wall of the second rotating rod 23, and the other end of the first driving rope 24 is fixedly connected to the side wall of the second sliding plate 13 close to the door panel 16. A second driving rope 25 is wound around the second rotating rod 23. One end of the second driving rope 25 is fixedly connected to the outer side wall of the second rotating rod 23, and the other end of the second driving rope 25 is fixedly connected to the top of the second sliding plate 13 through the first sliding plate 12.

A guiding member 3 for guiding the first sliding plate 12 and the second sliding plate 13 is arranged on the inner wall of the processing box 1.

[0038] When it is necessary to drive the first sliding plate 12 and the second sliding plate 13 to move in the direction close to the door panel 16, first start the motor 22. The output end of the motor 22 drives the second rotating rod 23 to rotate. The second rotating rod 23 tightens the first driving rope 24 and simultaneously relaxes the second driving rope 25, so as to facilitate driving the first sliding plate 12 and the second sliding plate 13 to move. At the same time, under the guiding action of the guiding member 3, it is convenient to drive the first sliding plate 12 and the second sliding plate 13 to move in a straight line. When it is necessary to drive the first sliding plate 12 to reset, by reversing the rotation of the motor 22, it is convenient to tighten the second driving rope 25 and relax the first driving rope 24, so as to facilitate driving the first sliding plate 12 to reset.

[0039] As Figure 2 shown, the guiding member 3 includes a guiding rod 31. The cross-section of the guiding rod 31 is circular and is arranged along the length direction of the processing box 1. The guiding rod 31 is welded to the inner wall of the processing box 1. The guiding rod 31 is slidably matched with the first sliding plate 12, and the guiding rod 31 penetrates through the first sliding plate 12.

[0040] When it is necessary to guide the first sliding plate 12 and the second sliding plate 13, through the arrangement of the guiding rod 31, it is convenient to reduce the possibility of the first sliding block deviating during the movement, so as to facilitate driving the first sliding plate 12 and the second sliding plate 13 to move in a straight line.

[0041] As Figure 2 and Figure 3As shown, the driving member 4 includes a plurality of sliding rods 41. The cross-section of the sliding rod 41 is circular and is arranged in the vertical direction. The sliding rod 41 is fixedly connected to the side wall of the first sliding plate 12 close to the second sliding plate 13. The second sliding plate 13 is slidably matched with the sliding rod 41. A spring 42 is sleeved on the outer side wall of the sliding rod 41. The spring 42 is arranged in the vertical direction. One end of the spring 42 is fixedly connected to the side wall of the first sliding plate 12, and the other end of the spring 42 is fixedly connected to the side wall of the second sliding plate 13.

[0042] When it is necessary to drive the second sliding plate 13 to abut against the vibrating sieve plate 11, at this time the spring 42 is in a compressed state. First, the motor 22 is used to drive the second rotating rod 23 to rotate, and the second rotating rod 23 relaxes the second driving rope 25. At this time, the second sliding plate 13 moves vertically downward under the elastic force of the spring 42, so as to facilitate driving the second sliding plate 13 to abut against the vibrating sieve plate 11, and further facilitate driving the tailings on the vibrating sieve plate 11 to move.

The cross-section of the third rotating rod 52 is circular and is arranged in the width direction of the processing box 1. A ratchet tooth 53 is fixedly sleeved on the outer side wall of the third rotating rod 52. The ratchet tooth 53 is engaged with the ratchet wheel 51. A torsion spring 54 is sleeved on the outer side wall of the third rotating rod 52. One end of the torsion spring 54 is fixedly connected to the side wall of the processing box 1, and the other end of the torsion spring 54 is fixedly connected to the side wall of the ratchet tooth 53. A first handle 55 is welded to the end of the third rotating rod 52 far from the processing box 1. The cross-section of the first handle 55 is circular and is arranged in the width direction of the processing box 1.

[0044] When it is necessary to release the limiting effect on the first rotating rod 15, first, the operator manually drives the first handle 55 to rotate. The first handle 55 drives the third rotating rod 52 to rotate, and the third rotating rod 52 drives the ratchet tooth 53 to rotate, so as to facilitate compressing the torsion spring 54. When the ratchet tooth 53 is separated from the ratchet wheel 51, the limiting effect of the ratchet tooth 53 on the ratchet wheel 51 can be released, and further the limiting effect on the first rotating rod 15 can be released. Then, the operator manually drives the door panel 16 to rotate. When the door panel 16 rotates a certain angle, the operator releases the first handle 55. At this time, the ratchet tooth 53 drives the ratchet tooth 53 to rotate under the elastic force of the torsion spring 54. When the ratchet tooth 53 abuts against the ratchet wheel 51, the first rotating rod 15 can be limited, and further the door panel 16 can be limited.

[0045] As Figure 2As shown in the figure, a slope 56 is provided on the side wall of the second sliding plate 13 close to the vibrating sieve plate 11. When it is necessary to drive the second sliding plate 13 to abut against the vibrating sieve plate 11, due to the provision of the slope 56, it is convenient to reduce the possibility that tailings are stuck between the second sliding plate 13 and the vibrating sieve plate 11, thereby facilitating the movement of the tailings on the vibrating sieve plate 11.

The cross-section of the relief groove 57 is square and extends in the vertical direction. The door panel 16 can abut against the inner wall of the relief groove 57. When it is necessary to drive the door panel 16 to rotate, due to the provision of the relief groove 57, it is convenient to rotate the door panel 16 into the relief groove 57, thereby facilitating the storage of the door panel 16.

[0047] As Figure 4 and Figure 5 shown in the figure, a second handle 58 is fixedly connected to the end of the first rotating rod 15 away from the ratchet wheel 51. The cross-section of the second handle 58 is circular and is arranged along the length direction of the processing box 1. When it is necessary to drive the door panel 16 to rotate, due to the provision of the second handle 58, it is convenient for the operator to manually drive the door panel 16 to rotate.

[0048] The implementation principle of a tailings re-election device according to an embodiment of the present application is as follows:

[0049] When it is necessary to clean the tailings on the vibrating sieve plate 11, first release the limiting effect of the limiting member 5 on the first rotating rod 15, and then manually drive the door panel 16 to rotate by the operator. When the door panel 16 rotates by a certain angle, limit the first rotating rod 15 through the limiting member 5, thereby facilitating the limitation of the door panel 16. Then drive the second sliding plate 13 to move vertically downward through the driving member 4. When the second sliding plate 13 abuts against the vibrating sieve plate 11, drive the first sliding plate 12 and the second sliding plate 13 to move together in the direction close to the door panel 16 through the driving member 2, thereby facilitating the movement of the tailings with larger particle size accumulated on the vibrating sieve plate 11 into the collection box 17, and further facilitating the operation of the vibrating sieve plate 11.
