Description

Technical Field

[0001] The present invention relates to the technical field of mining shaking tables, and particularly to a gravity shaking table device for beneficiating new stone ores. Background Art

[0002] A beneficiating shaking table is a widely used gravity separation beneficiation equipment. The beneficiating shaking table utilizes the specific gravity difference between the target minerals and gangue minerals, and realizes the separation of the target minerals and gangue minerals through the combined action of mechanical vibration and water flow scouring. During beneficiation, the ore raw materials will successively form a concentrate layer, a middling layer, and a tailings layer on the bed surface. The middling layer is the intermediate substance between the concentrate and the tailings. After collecting the middling, it needs to be put on the shaking table for further processing to separate the concentrate and tailings in the middling.

[0003] Authorized, the Chinese patent document with the publication number CN118268119B discloses a gravity shaking table beneficiation equipment and a beneficiation method for zircon sand. This patent includes a bed body and a recovery unit arranged on the bed body. Through the setting of the recovery unit, when the equipment beneficiates the raw materials, the generated middling will be mixed with water and collected into a recovery tank by the recovery hopper of the recovery unit to form a middling dilution liquid. The recovery hopper can be adjusted to a suitable position according to the positions of the various ore layers formed by different types of ore raw materials on the bed body to collect the generated middling, thereby improving the applicability of the device. After the recovery tank has collected a certain amount of middling dilution liquid, the middling dilution liquid in the recovery tank is automatically transported back to the bed body by a feed pump for re-beneficiation, without the need for long-term manual supervision, making the recovery and gravity separation process of the middling very simple, thereby improving the beneficiation efficiency of the equipment and can be adjusted as needed.

[0004] Based on retrieval and the prior art, it is found that the existing shaking table is driven by a shaking head to perform an asymmetric reciprocating linear motion on the same plane, and the loose stratification of minerals on the bed surface is mainly achieved by the lateral flushing water flow; the function of the lateral water flow is relatively single, that is, only a lateral driving force is applied to the ore to achieve stratification. If a vertical vibration force is applied to the shaking table and the principle of specific gravity screening is used, the stratification effect will be further improved, thereby improving the accuracy of beneficiation.

Detailed implementation manners

[0043] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] The present invention provides a new gravity - type shaking table device for stone ore dressing by improvement. The technical solution of the present invention is as follows:

[0045] As Figures 1 to 11As shown in the figure, an embodiment of the present invention provides a gravity shaker device for a new type of stone ore beneficiation, including a bed plate 4, a slide plate 2, and a chassis 1;

[0046] Explanation of the bed plate 4: The bed plate 4 is a prior art, and the specific structure and working principle of the bed plate 4 will not be elaborated. Only its structure is simply shown in the attached drawings;

[0047] Combined with the attached Figure 1 and the attached Figure 2 As shown, a plurality of vertical plates 8 are fixed on one side of the bed plate 4. The tops of the plurality of vertical plates 8 are jointly fixed with a diversion trough 5. A plurality of flow outlets are opened at the bottom of the diversion trough 5. A water trough 6 and an ore trough 7 are fixed at the top of the trough opening of the diversion trough 5. Pour a certain concentration of pulp into the ore trough 7, and then the pulp flows into the diversion trough 5 through the ore trough 7. A water faucet is arranged above the water trough 6, and the water faucet pours water into the water trough 6 at a certain flow rate. Then the water flows into the diversion trough 5 through the water trough 6. After the water is mixed with the pulp, it flows from the flow outlet of the diversion trough 5 to the bed plate 4;

[0048] A sliding structure for linearly sliding the slide plate 2 is arranged on the top of the chassis 1;

[0049] An adjusting mechanism for adjusting the inclination of the bed plate 4 is arranged on the top of the slide plate 2;

[0050] Combined with the attached Figures 1 to 9 As shown, a plurality of hammering mechanisms are arranged on the chassis 1. The hammering mechanism includes a third concave block 32 fixed to the chassis 1. A rotating block 36 is rotatably installed in the concave opening of the third concave block 32. A limiting plate 46 is fixed on one side of the concave opening of the third concave block 32. An elastic structure is arranged on one side of the third concave block 32. The elastic structure applies a pulling force to the rotating block 36 to make the rotating block 36 contact the limiting plate 46. A double-joint telescopic cylinder 37 is fixed to the top of the rotating block 36. The top of the double-joint telescopic cylinder 37 is fixed with a supporting concave block 40. A contact wheel 41 is arranged in the concave opening of the supporting concave block 40. Counterbores are opened at both ends of the supporting concave block 40. A rotating structure for rotating the contact wheel 41 is jointly arranged in the two counterbores. Limiting rings 38 are fixed at both ends of the double-joint telescopic cylinder 37. A second spring 39 is sleeved outside the double-joint telescopic cylinder 37. The two ends of the second spring 39 are respectively in contact with the two limiting rings 38. A plurality of inclined blocks 26 are fixed to the bottom of the bed plate 4; As attached Figure 5 and attached Figure 6For example, when the bed board 4 moves to the left, the inclined block 26 on the bed board 4 moves backward together with the bed board 4. The inclined block 26 contacts the contact wheel 41. Due to the setting of the limit plate 46, the rotating block 36 cannot rotate to the left in the third concave block 32. At this time, the double-joint telescopic cylinder 37 of the rotating block 36 is shortened passively, and the second spring 39 is compressed, enabling the double-joint telescopic cylinder 37 to have the ability to reset. When the contact wheel 41 disengages from the inclined block 26, the second spring 39 quickly elongates. At this time, the double-joint telescopic cylinder 37 quickly resets, and the contact wheel 41 hammers the bed board 4, thereby generating a vibration in the vertical direction of the bed board 4, making it easier for the ore to be stratified. When the bed board 4 moves to the right, the inclined block 26 pushes the contact wheel 41, causing the double-joint telescopic cylinder 37 to rotate to the right;

[0051] One end of the chassis 1 is provided with a driving assembly for driving the bed board 4 to perform reciprocating linear movement.

[0052] Specifically, in combination with the attached Figure 2 and the attached Figure 4 As shown, the sliding structure includes a plurality of slide rails 3. The plurality of slide rails 3 are parallel to each other and are all fixed to the chassis 1. A plurality of sliders are slidably arranged on the rail surface of each slide rail 3. In order to reduce frictional losses, ball sliders can be selected. The plurality of sliders are all fixed to the slide plate 2. From the above connection relationship, it can be seen that the sliding structure is provided to enable the slide plate 2 to only move linearly relative to the chassis 1, that is, the bed board 4 can only move linearly relative to the chassis 1.

[0053] Specifically, in combination with the attached Figure 1 and the attached Figure 2 and the attached Figure 3 and the attached Figure 4 As shown, the adjusting mechanism includes two first support columns 9, two second support columns 24, one adjusting block 16, one adjusting rod 17, and two first concave blocks 10;

[0054] Among them, as shown in the attached Figure 2 As shown, one ends of the two first support columns 9 are respectively fixed at both ends of one side of the bottom of the bed board 4, and the other ends of the two first support columns 9 are respectively rotatably installed in the notches of the two first concave blocks 10, and the two first concave blocks 10 are both fixed to the slide plate 2; the first support column 9 can rotate in the first concave block 10. Since the first support column 9 is fixed to the bed board 4, the first support column 9 can drive the bed board 4 to rotate;

[0055] Among them, as shown in the attached Figure 3 and the attached Figure 4As shown, one end of each of the two second support columns 24 is fixed at both ends of the other side of the bottom of the bed board 4, and fixed blocks 25 are fixed at the other ends of the two second support columns 24. Both ends of the adjusting rod 17 are fixed to the two fixed blocks 25 respectively. A plurality of guide bars 21 with a T-shaped cross-section are fixed to the top of the sliding plate 2, and the adjusting block 16 is slidably sleeved on the guide bars 21. An inclined groove 18 opening is formed on the outer side of the adjusting block 16, and the adjusting rod 17 is slidably arranged in the inclined groove 18 opening. A adjusting structure for adjusting the position of the adjusting block 16 on the guide bars 21 is arranged on the top of the sliding plate 2; move the adjusting block 16, and the adjusting rod 17 slides in the inclined groove 18 opening of the adjusting block 16 to attach Figure 2 and attach Figure 3 For example, when the adjusting block 16 is moved backward, the adjusting rod 17 moves downward along the inclined groove 18. At this time, the bed board 4 inclines downward, and at the same time, the first support column 9 can rotate in the direction of the inclination of the bed board 4 in the first concave block 10.

[0056] Specifically, as shown in attachment Figure 3 shown, the adjusting structure includes a reference block 20 and an adjusting column 19;

[0057] Among them, the reference block 20 is fixed to the sliding plate 2. A threaded hole is formed on the outer side of the reference block 20. One end of the adjusting column 19 is provided with a thread, and the adjusting column 19 is installed in the threaded hole through the thread. A handle is fixed to the end of the adjusting column 19 where the thread is provided to attach Figure 2 and attach Figure 3 For example, the worker rotates the adjusting column 19 through the handle, and the threaded end of the adjusting column 19 moves backward in the threaded hole on the reference block 20, and the adjusting column 19 pulls the adjusting block 16 backward.

[0058] Specifically, in combination with attachment Figure 8 and attachment Figure 9 shown, the elastic structure includes a first positioning column 33, a tension spring 34 and a second positioning column 35;

[0059] Among them, the first positioning column 33 is fixed to the third concave block 32, and the first positioning column 33 is close to the limiting plate 46. The second positioning column 35 is fixed to the rotating block 36, and the second positioning column 35 is far from the limiting plate 46. Both ends of the tension spring 34 are fixed to the first positioning column 33 and the second positioning column 35 respectively. Here, a supplementary description is made for the tension spring 34. The tension spring 34 is in a stretched state; when the bed board 4 moves to the right, the inclined block 26 pushes the contact wheel 41, so that the double-joint telescopic cylinder 37 rotates to the right. At this time, the tension spring 34 is stretched, and the rotating block 36 has the ability to reset. Without external force, the tension spring 34 always exerts a pulling force on the second positioning column 35 on the rotating block 36, so that the rotating block 36 contacts the limiting plate 46.

[0060] Specifically, in combination with attachment Figure 10As shown, the rotating structure includes an intermediate column 44, a one-way bearing 45, and a coil spring 43;

[0061] Both ends of the intermediate column 44 are rotatably installed in the small holes of the counterbore. The inner ring of the one-way bearing 45 is fixedly coaxially connected with the intermediate column 44, and the outer ring of the one-way bearing 45 is fixedly coaxially connected with the contact wheel 41. Both ends of the coil spring 43 are respectively fixed on the intermediate column 44 and the inner wall of the large hole of the counterbore to Figure 5 attach and Figure 6 Taking... as an example, when the bed board 4 moves to the left, the inclined block 26 on the bed board 4 moves backward together with the bed board 4. The inclined block 26 contacts the contact wheel 41. At this time, the contact wheel 41 can drive the intermediate column 44 to rotate by means of the one-way bearing 45. The intermediate column 44 drives the coil spring 43 to wind. The coil spring 43 applies a reverse winding force to the intermediate column 44. When the bed board 4 moves to the right, the inclined block 26 pushes the contact wheel 41. At this time, the contact wheel 41 cannot drive the intermediate column 44 to rotate.

[0062] Specifically, in combination with Figure 6 and Figure 8 shown, a rubber sleeve 42 for increasing the friction force is fixedly sleeved on the outer side of the contact wheel 41, and a rubber layer 27 for increasing the friction force is fixed on the inclined surface of the inclined block 26.

[0063] Specifically, in combination with Figure 2 , Figure 4 and Figure 7 shown, the drive assembly includes a drive motor 11, a first transmission wheel 12, a second transmission wheel 15, a transmission belt 13, a bracket 14, a circular plate 22, a concave frame 28, a second concave block 31, a plurality of flat head columns 29, and a plurality of first springs 30;

[0064] Among them, the support 14 is fixed to the chassis 1. A rotation hole is provided on the outer side of the support 14. A synchronous shaft is rotatably installed inside the rotation hole. Both ends of the synchronous shaft are coaxially fixed to the circular plate 22 and the second transmission wheel 15 respectively. The driving motor 11 is fixed to the chassis 1. The output shaft of the driving motor 11 is coaxially fixed to the first transmission wheel 12. The transmission belt is sleeved on the first transmission wheel 12 and the second transmission wheel 15. One end of the connecting rod 23 is rotatably installed at a non-central position on the circular surface of the circular plate 22, and the other end of the connecting rod 23 is rotatably installed in the notch of the second concave block 31. After determining the slope of the bed board 4, then fix both ends of the concave frame 28 on one end of the bed board 4. A plurality of sliding holes are provided on the outer side of the concave frame 28. The non-flat ends of a plurality of flat-headed columns 29 are all fixed to the second concave block 31, and the plurality of flat-headed columns 29 are respectively slidably inserted into the respective sliding holes. A plurality of first springs 30 are respectively sleeved on the respective flat-headed columns 29, and both ends of the first spring 30 are respectively in contact with the flat head end of the flat-headed column 29 and the concave frame 28; the driving motor 11 rotates the first transmission wheel 12 through the output shaft, the first transmission wheel 12 rotates the second transmission wheel 15 through the transmission belt 13, the second transmission wheel 15 rotates the circular plate 22 through the synchronous shaft, and the circular plate 22 reciprocally pushes and pulls the second concave block 31 through the connecting rod 23.

[0065] Supplement and explanation for the above: After determining the slope of the bed board 4, that is, adjusting the bed board 4, then fix the third concave block 32 in the hammering mechanism on the chassis 1. When fixing, ensure that the double-section telescopic cylinder 37 in the hammering mechanism is perpendicular to the bed board 4, so that the wheel surface of the contact wheel 41 in the hammering mechanism can be well attached to the inclined surface of the inclined block 26.

[0066] Working principle:

[0067] Pour the pulp with a certain concentration into the ore trough 7. Then the pulp flows into the diversion trough 5 through the ore trough 7. A water faucet is arranged above the water trough 6, and the water faucet pours water into the water trough 6 at a certain flow rate. Then the water flows into the diversion trough 5 through the water trough 6. After the water is mixed with the pulp, it flows out from the outlet of the diversion trough 5 to the bed board 4;

[0068] Take Figure 2 and Figure 3 as an example. The worker rotates the adjusting column 19 through the handle. The threaded end of the adjusting column 19 moves backward in the threaded hole on the reference block 20. The adjusting column 19 pulls the adjusting block 16 to move backward, and the adjusting rod 17 moves downward along the inclined groove 18. At this time, the bed board 4 tilts downward, and at the same time, the first support column 9 can rotate in the direction of the inclination of the bed board 4 in the first concave block 10;

[0069] After determining the slope of the bed board 4, then fix both ends of the concave frame 28 on one end of the bed board 4;

[0070] After determining the inclination of the bedplate 4, that is, adjusting the bedplate 4, then fix the third concave block 32 in the hammering mechanism on the chassis 1. When fixing, ensure that the double-jointed telescopic cylinder 37 in the hammering mechanism is perpendicular to the bedplate 4, so that the wheel surface of the contact wheel 41 in the hammering mechanism can well fit with the inclined surface of the inclined block 26;

[0071] Start the driving motor 11. The driving motor 11 drives the first transmission wheel 12 to rotate through the output shaft. The first transmission wheel 12 drives the second transmission wheel 15 to rotate through the transmission belt 13. The second transmission wheel 15 drives the circular plate 22 to rotate through the synchronous shaft. The circular plate 22 reciprocally pushes and pulls the second concave block 31 through the connecting rod 23;

[0072] Take Figure 5 and Figure 6 as an example. When the bedplate 4 moves to the left, the inclined block 26 on the bedplate 4 moves backward together with the bedplate 4. The inclined block 26 contacts the contact wheel 41. Due to the setting of the limit plate 46, the rotating block 36 cannot rotate to the left in the third concave block 32. At this time, the double-jointed telescopic cylinder 37 of the rotating block 36 is passively shortened, and the second spring 39 is compressed, enabling the double-jointed telescopic cylinder 37 to have the ability to reset. At this time, the contact wheel 41 can drive the middle column 44 to rotate by means of the one-way bearing 45. The middle column 44 drives the winding spring 43 to wind. The winding spring 43 exerts a reverse winding force on the middle column 44. At this time, the resistance of the bedplate 4 increases, the speed of the bedplate 4 gradually slows down, the second concave block 31 and the concave frame 28 are separated from each other, and the flat head end of the flat head column 29 compresses the first spring 30. When the contact wheel 41 breaks away from the inclined block 26, the second spring 39 quickly elongates. At this time, the double-jointed telescopic cylinder 37 quickly resets, and the contact wheel 41 hammers the bedplate 4, thereby generating a vibration in the vertical direction of the bedplate 4, making it easier for the ore to be stratified. At the same time, the first spring 30 quickly resets, and the bedplate 4 undergoes a rapid acceleration. The reset contact wheel 41 will contact the next inclined block 26, repeating the above process. It can be seen that during the leftward movement of the bedplate 4, the hammering mechanism can hammer the lower part of the bedplate 4 multiple times, thereby generating a vibration in the vertical direction of the bedplate 4, making it easier for the ore to be stratified and improving the ore dressing efficiency; at the same time, the hammering mechanism can exert intermittent resistance on the bedplate 4, enabling the bedplate 4 to undergo multiple rapid accelerations and decelerations during the reset process, so that the bedplate 4 can vibrate at a high frequency during the reset process, enabling the entire bedplate 4 to complete multiple vibrations in a reciprocating process, further improving the screening effect of the ore.

[0073] When the bedplate 4 moves to the right, the inclined block 26 pushes the contact wheel 41, causing the double-jointed telescopic cylinder 37 to rotate to the right. The inclined block 26 pushes the contact wheel 41. At this time, the contact wheel 41 cannot drive the middle column 44 to rotate. The second concave block 31 pushes the bedplate 4 through the concave frame 28. At this time, the bedplate 4 cannot be blocked and slowed down. It can be seen that during the reciprocating process of the bedplate 4, it is an asymmetric reciprocating motion, making it easier for the ore to be stratified.
