Description

Technical Field

[0001] The invention relates to the technical field of mining shaking tables, in particular to a novel gravity shaking table device for stone ore dressing. Background Art

[0002] The ore dressing shaking table is a widely used gravity separation equipment. The ore dressing shaking table uses the difference in specific gravity between the target mineral and the gangue mineral to separate the target mineral from the gangue mineral through the combined effect of mechanical vibration and water flow scouring. During the ore dressing, the ore raw materials will form a concentrate layer, a middling layer and a tailings layer on the bed surface in sequence. The middling layer is the intermediate between the concentrate and the tailings. After collecting the middling, it needs to be placed on the shaking table for further processing to separate the concentrate from the tailings in the middling.

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

[0004] Based on the search and prior art findings: the existing shaking table is driven by the shaking table head to perform asymmetric reciprocating linear motion on the same plane, and the loose stratification of minerals on the bed surface is mainly achieved by the horizontal flushing water flow; the role of the horizontal water flow is relatively simple, that is, only a horizontal driving force is applied to the ore to achieve stratification. If a vertical vibration force is applied to the shaking table, the principle of specific gravity screening will be used to further improve the stratification effect, thereby improving the accuracy of mineral processing.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The present invention provides a new type of gravity shaking table equipment for stone ore dressing through improvement. The technical solution of the present invention is: like Figures 1 to 11 As shown, the embodiment of the present invention provides a novel gravity shaking table equipment for stone ore dressing, including a bed plate 4, a slide plate 2 and a base frame 1; The bed board 4 is described as a prior art. The specific structure and working principle of the bed board 4 are not described here. The accompanying drawings only show its structure. Combined with Figure 1 and attached Figure 2 As shown, a plurality of vertical plates 8 are fixed on one side of the bed plate 4, and a diversion trough 5 is fixed on the top of the plurality of vertical plates 8. A plurality of flow outlets are provided at the bottom of the diversion trough 5, and a water flow trough 6 and an ore trough 7 are fixed on the top of the trough opening of the diversion trough 5. A certain concentration of ore pulp is poured into the ore trough 7, and the ore pulp then flows into the diversion trough 5 through the ore trough 7. A faucet is provided above the water flow trough 6, so that the faucet pours water into the water flow trough 6 at a certain flow rate, and the water then flows into the diversion trough 5 through the water flow trough 6. After the water is mixed with the ore pulp, it flows from the flow outlet of the diversion trough 5 to the bed plate 4; The top of the base frame 1 is provided with a sliding structure for enabling the slide plate 2 to slide linearly; The top of the slide plate 2 is provided with an adjustment mechanism for adjusting the inclination of the bed board 4; Combined with Figures 1 to 9 As shown, a plurality of hammer mechanisms are arranged on the base frame 1, and the hammer mechanisms include a third recessed block 32 fixed to the base frame 1, a rotating block 36 is rotatably installed in the recess of the third recessed block 32, a limiting plate 46 is fixed on one side of the recess of the third recessed block 32, an elastic structure is arranged on one side of the third recessed block 32, the elastic structure applies a pulling force to the rotating block 36 to make the rotating block 36 contact with the limiting plate 46, a double-section telescopic cylinder 37 is fixed on the top of the rotating block 36, a supporting recessed block 40 is fixed on the top of the double-section telescopic cylinder 37, a contact wheel 41 is arranged in the recess of the supporting recessed block 40, countersunk holes are provided at both ends of the supporting recessed block 40, a rotating structure for rotating the contact wheel 41 is arranged in the two countersunk holes, limiting rings 38 are fixed on both ends of the double-section telescopic cylinder 37, a second spring 39 is sleeved on the outer side of the double-section telescopic cylinder 37, and the two ends of the second spring 39 are respectively in contact with the two limiting rings 38, and a plurality of inclined blocks 26 are fixed on the bottom of the bed board 4; Figure 5 and attached Figure 6 For example, when the bed plate 4 moves to the left, the inclined block 26 on the bed plate 4 moves backward with the bed plate 4, and 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 recessed block 32. At this time, the double-section telescopic cylinder 37 of the rotating block 36 is passively shortened, and the second spring 39 is compressed, so that the double-section telescopic cylinder 37 has the ability to reset. When the contact wheel 41 is separated from the inclined block 26, the second spring 39 is rapidly extended. At this time, the double-section telescopic cylinder 37 is rapidly reset, and the contact wheel 41 hammers the bed plate 4, so that the bed plate 4 generates a vibration in the vertical direction, making it easier to stratify the ore. When the bed plate 4 moves to the right, the inclined block 26 pushes the contact wheel 41, causing the double-section telescopic cylinder 37 to rotate to the right. One end of the base frame 1 is provided with a driving assembly for driving the bed board 4 to perform reciprocating linear movement.

[0021] Specifically, in combination with Figure 2 And attached Figure 4 As shown, the sliding structure includes a plurality of slide rails 3, and the plurality of slide rails 3 are parallel to each other and are fixed to the base frame 1. A plurality of sliders are slidably arranged on the rail surface of each slide rail 3. In order to reduce friction loss, a ball slider can be selected. The plurality of sliders are fixed to the slide plate 2. It can be known from the above connection relationship that the sliding structure is arranged so that the slide plate 2 can only move linearly relative to the base frame 1, that is, the bed board 4 can only move linearly relative to the base frame 1.

[0022] Specifically, in combination with Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, the adjustment mechanism includes two first support columns 9, two second support columns 24, an adjustment block 16, an adjustment rod 17 and two first concave blocks 10; Among them, as attached Figure 2 As shown, one end of the two first support columns 9 is respectively fixed at the two end positions 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 fixed to the slide plate 2; the first support column 9 can rotate in the first concave blocks 10, and because 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; Among them, as attached Figure 3 And attached Figure 4 As shown, one end of the two second support columns 24 is respectively fixed at the two end positions on the other side of the bottom of the bed board 4, and the other ends of the two second support columns 24 are fixed with fixed blocks 25, and the two ends of the adjusting rod 17 are respectively fixed with the two fixed blocks 25, and the top of the slide plate 2 is fixed with a plurality of guide bars 21 with a T-shaped cross section, and the adjusting block 16 is slidably sleeved on the guide bar 21, and the outer side of the adjusting block 16 is provided with an oblique groove 18, and the adjusting rod 17 is slidably set in the oblique groove 18, and the top of the slide plate 2 is provided with an adjusting structure for adjusting the position of the adjusting block 16 on the guide bar 21; the adjusting block 16 is moved, and the adjusting rod 17 slides in the oblique groove 18 on the adjusting block 16 to attach Figure 2 and attached Figure 3 For example, the adjusting block 16 is moved backward, and the adjusting rod 17 is moved downward along the inclined slot 18 . At this time, the bed board 4 tilts downward, and at the same time, the first supporting column 9 can rotate in the first concave block 10 in the tilting direction of the bed board 4 .

[0023] Specifically, as attached Figure 3 As shown, the adjustment structure includes a reference block 20 and an adjustment column 19; The reference block 20 is fixed to the slide plate 2, a threaded hole is provided on the outer side of the reference block 20, a thread is provided on one end of the adjusting column 19, and the adjusting column 19 is installed in the threaded hole through the thread, and the other end of the adjusting column 19 is rotatably installed on the end of the adjusting column 19 where a handle is fixed to attach the adjusting column 19. Figure 2 and attached Figure 3 For example, a worker rotates the adjusting column 19 by a 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 to move backward.

[0024] Specifically, in combination with Figure 8 And attached Fig. 9 As shown, the elastic structure includes a first positioning column 33, a tension spring 34 and a second positioning column 35; Among them, the first positioning column 33 is fixed to the third recessed 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 away from the limiting plate 46, and the two ends of the tension spring 34 are respectively fixed to the first positioning column 33 and the second positioning column 35. Here, the tension spring 34 is supplemented. The tension spring 34 is in an extended state; when the bed board 4 moves to the right, the inclined block 26 pushes the contact wheel 41 to make the double-section telescopic cylinder 37 rotate to the right. At this time, the tension spring 34 is extended, and the rotating block 36 has the ability to reset. In the absence of external force, the tension spring 34 always applies tension to the second positioning column 35 on the rotating block 36, so that the rotating block 36 contacts the limiting plate 46.

[0025] Specifically, in combination with Fig.10 As shown, the rotating structure includes an intermediate column 44, a one-way bearing 45 and a coil spring 43; The two ends of the intermediate column 44 are rotatably mounted in the small hole of the countersunk hole, the inner ring of the one-way bearing 45 is coaxially fixed with the intermediate column 44, and the outer ring of the one-way bearing 45 is coaxially fixed with the contact wheel 41, and the two ends of the coil spring 43 are respectively fixed on the intermediate column 44 and the inner wall of the large hole of the countersunk hole to attach Figure 5 and attached Figure 6 For example, when the bed board 4 moves to the left, the inclined block 26 on the bed board 4 moves backward with the bed board 4, and the inclined block 26 contacts the contact wheel 41. At this time, the contact wheel 41 can drive the middle column 44 to rotate with the help of the one-way bearing 45, and the middle column 44 drives the coil spring 43 to wind, and the coil spring 43 applies a reverse winding force to the middle column 44. When the bed board 4 moves to the right, the inclined block 26 pushes the contact wheel 41, and at this time the contact wheel 41 cannot drive the middle column 44 to rotate.

[0026] Specifically, in combination with Figure 6 And attached Figure 8 As shown, a rubber sleeve 42 for increasing friction is fixedly sleeved on the outer side of the contact wheel 41, and a rubber layer 27 for increasing friction is fixedly mounted on the inclined surface of the inclined block 26.

[0027] Specifically, in combination with Figure 2 , Attachment Figure 4 And attached Figure 7 As shown, the driving assembly includes a driving motor 11, a first transmission wheel 12, a second transmission wheel 15, a transmission belt 13, a bracket 14, a circular plate 22, a recessed frame 28, a second recessed block 31, a plurality of flat-headed columns 29 and a plurality of first springs 30; Among them, the bracket 14 is fixed to the base frame 1, a rotating hole is opened on the outer side of the bracket 14, and a synchronous shaft is rotatably installed inside the rotating hole. The two ends of the synchronous shaft are coaxially fixed to the circular plate 22 and the second transmission wheel 15 respectively. The drive motor 11 is fixed to the base frame 1, and the output shaft of the drive 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 the non-center of the circular surface of the circular plate 22, and the other end of the connecting rod 23 is rotatably installed in the recess of the second recess block 31. After determining the inclination of the bed board 4, the two ends of the recessed frame 28 are then fixed to one end of the bed board 4. A plurality of sliding holes are provided on the outer side of the recessed frame 28, the non-flat ends of the plurality of flat-headed columns 29 are fixed on the second recessed block 31, and the plurality of flat-headed columns 29 are slidably inserted in the respective sliding holes, and the plurality of first springs 30 are respectively sleeved on the respective flat-headed columns 29, and the two ends of the first springs 30 are respectively in contact with the flat ends of the flat-headed columns 29 and the recessed 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 pushes and pulls the second recessed block 31 reciprocatingly through the connecting rod 23.

[0028] To supplement the above: after determining the inclination of the bed board 4, that is, adjusting the bed board 4, the third recessed block 32 in the hammer mechanism is fixed to the base frame 1. When fixing, ensure that the double-section telescopic cylinder 37 in the hammer mechanism is perpendicular to the bed board 4, so that the wheel surface of the contact wheel 41 in the hammer mechanism can fit well with the inclined surface of the inclined block 26.

[0029] Working principle: Pour a certain concentration of ore pulp into the ore trough 7, and then the ore pulp flows into the diversion trough 5 through the ore trough 7. A faucet is provided above the water flow trough 6, so that the faucet pours water into the water flow trough 6 at a certain flow rate, and then the water flows into the diversion trough 5 through the water flow trough 6. After the water is mixed with the ore pulp, it flows from the outflow port of the diversion trough 5 to the bed plate 4; Attach Figure 2 and attached Figure 3 For example, a worker rotates the adjusting column 19 by a 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, 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 supporting column 9 can rotate in the first concave block 10 in the tilting direction of the bed board 4; After determining the inclination of the bed board 4, the two ends of the recessed frame 28 are then fixed to one end of the bed board 4; After the inclination of the bed board 4 is determined, that is, the bed board 4 is adjusted, the third concave block 32 in the hammer mechanism is fixed on the base frame 1, and the double-section telescopic cylinder 37 in the hammer mechanism is ensured to be perpendicular to the bed board 4 during the fixing, so that the wheel surface of the contact wheel 41 in the hammer mechanism can be well fitted with the inclined surface of the inclined block 26; The driving motor 11 is started, and the driving motor 11 rotates the first transmission wheel 12 through the output shaft, and the first transmission wheel 12 rotates the second transmission wheel 15 through the transmission belt 13, and the second transmission wheel 15 rotates the circular plate 22 through the synchronous shaft, and the circular plate 22 reciprocates to push and pull the second concave block 31 through the connecting rod 23; Attach Figure 5 and attached Figure 6 For example, when the bed board 4 moves to the left, the inclined block 26 on the bed board 4 moves backward with the bed board 4, and 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 recessed block 32. At this time, the double-section telescopic cylinder 37 of the rotating block 36 is passively shortened, and the second spring 39 is compressed, so that the double-section telescopic cylinder 37 has the ability to reset. At this time, the contact wheel 41 can drive the middle column 44 to rotate with the help of the one-way bearing 45, and the middle column 44 drives the coil spring 43 to wind, and the coil spring 43 applies a reverse winding force to the middle column 44. At this time, the resistance of the bed board 4 increases, and the speed of the bed board 4 gradually slows down. The second recessed block 31 and the recessed 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 leaves the inclined block 26, the second spring 39 quickly extends. At this time, the double-section telescopic cylinder 3 7 is quickly reset, and the contact wheel 41 hammers the bed plate 4, thereby causing the bed plate 4 to vibrate in the vertical direction, making it easier for the ore to be stratified. At the same time, the first spring 30 is quickly reset, and the bed plate 4 is rapidly accelerated. The reset contact wheel 41 will contact the next inclined block 26 again, and the above process is repeated. It can be seen that during the movement of the bed plate 4 to the left, the hammering mechanism can hammer the bottom of the bed plate 4 multiple times, thereby causing the bed plate 4 to vibrate in the vertical direction, making it easier for the ore to be stratified, thereby improving the ore dressing efficiency; at the same time, the hammering mechanism can apply intermittent resistance to the bed plate 4, so that the bed plate 4 undergoes multiple rapid accelerations and slow decelerations during the resetting process, so that the bed plate 4 can vibrate at high frequency during the resetting process, so that the entire bed plate 4 completes multiple vibrations in a reciprocating process, thereby further improving the ore screening effect.

[0030] When the bed board 4 moves to the right, the inclined block 26 pushes the contact wheel 41, causing the double-section 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 recessed block 31 pushes the bed board 4 with the help of the recessed frame 28. At this time, the bed board 4 cannot be blocked and slowed down. It can be seen that the reciprocating process of the bed board 4 is an asymmetric reciprocating motion, which makes it easier for the ore to be stratified.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
