Description

Technical Field

[0001] This utility model relates to the field of mineral processing shaking tables, and in particular to a shaking table structure for ore separation and processing. Background Technology

[0002] In the field of mineral resource development and utilization, sorting technology is the core link to improve ore grade and increase resource utilization. As a classic mineral sorting equipment, the shaking table has been widely used in the mineral processing industry due to its significant advantages such as simple structure, convenient operation and low cost. Among them, the 6S shaking table, as a traditional and common model, achieves effective separation of different minerals by simulating the synergistic effect of natural gravity field and water flow dynamic field and utilizing the difference in movement of mineral particles on the table surface. It has long been a key tool for solving the problem of mineral sorting.

[0003] However, with the continuous deepening of mineral resource mining and the continuous improvement of mineral processing technology requirements, traditional sorting equipment such as 6S shaking tables have gradually exposed many unavoidable defects in practical applications. In particular, the problem of low sorting efficiency has become the main bottleneck restricting the improvement of mineral processing efficiency and resource recovery rate.

[0004] Specifically, the current 6S shaking table has the following main shortcomings in terms of sorting efficiency:

[0005] The current method of adding slurry is outdated. During the operation of the 6S shaking table, the addition of slurry mainly relies on manual labor. This method is not only labor-intensive, but also makes it difficult to accurately control the amount of slurry added. As a result, the ratio of slurry to water often deviates from the optimal range. Fluctuations in slurry concentration directly affect the movement of mineral particles on the table surface and the sorting effect. Slurry that is too thick will hinder the movement of mineral particles and make it difficult to achieve sufficient stratification. Slurry that is too thin will cause the movement of mineral particles to be too dispersed, resulting in reduced sorting accuracy and efficiency, while increasing the difficulty and cost of subsequent processing. Therefore, this application provides a shaking table structure for ore sorting to meet the requirements. Utility Model Content

[0006] The purpose of this application is to provide a shaking table structure for ore sorting, which solves the technical problems mentioned in the background above.

[0007] To achieve the above objectives, this application provides the following technical solution: a shaking table structure for ore sorting, comprising a base, a bed surface, a transmission mechanism, and a main motor, and further comprising:

[0008] Plate frame: driven by the transmission mechanism to achieve horizontal reciprocating movement on the top of the machine base, and the bed surface is arranged on the plate frame;

[0009] Lifting seat: Driven by a drive gear on the surface of the side plate of the machine base, it can be raised and lowered vertically at the top of the machine base. The lifting seat is used to adjust the slope of the bed surface.

[0010] Hopper and water box: are sequentially arranged on the surface of the side plate of the machine base;

[0011] Drive rod: Driven by an electric telescopic rod set on the side plate of the base, it can move horizontally back and forth on the inner wall of the discharge pipe of the hopper and water box. The surface of the drive rod is provided with a first material hole and a second material hole respectively corresponding to the positions of the two sets of discharge pipes. The surface of the drive rod is provided with a first tooth and a second tooth respectively corresponding to the positions of the outer gear ring on the surface of the drive gear and the potentiometer speed adjustment knob in the main motor, and they are meshed and connected.

[0012] Controller: Located on the surface of the side plate of the base, and connected to the main motor and the electric telescopic rod respectively.

[0013] In a preferred embodiment of this invention, one end of the bed surface is hinged to the top of one end of the frame, and a spring is fixedly connected between the bottom of the other end of the bed surface and the top of the other end of the frame. Rollers and through grooves are respectively provided at the bottom of the bed surface and the surface of the frame corresponding to the position of the lifting seat. The lifting seat is located inside the through groove, and a guide groove is provided at the top of the lifting seat corresponding to the position of the roller. The roller is located in the guide groove and is slidably connected to the inner wall of the guide groove.

[0014] In a preferred embodiment of this invention, a column groove is provided at the top of the base corresponding to the position of the lifting seat, and a reciprocating screw is threadedly connected to the inner wall of the column groove. The lifting seat is threadedly connected to the outer surface of the reciprocating screw and vertically slidably connected to the inner wall of the column groove. One end of the reciprocating screw passes through the interior of the base and is fixedly connected to a first bevel gear. A second bevel gear is rotatably connected to one side of the first bevel gear and they mesh with each other. Synchronous gears are respectively provided at the corresponding positions of the surface of the central shaft of the second bevel gear and the surface of the drive gear, and they are connected by a synchronous toothed belt.

[0015] In a preferred embodiment of this invention, both the first and second material holes are funnel-shaped. There are two sets of the first and second material holes, and the spacing between the two sets of the first material holes is the same as the spacing between the two sets of the second material holes. The internal space of the first material hole closer to the electric telescopic rod is smaller than the internal space of the first material hole farther from the electric telescopic rod, and the internal space of the second material hole closer to the electric telescopic rod is smaller than the internal space of the second material hole farther from the electric telescopic rod.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] This invention has a reasonable structure. It is equipped with a hopper, a water box, and a transmission rod. The transmission rod is horizontally slidably connected to the inner wall of the discharge pipe of the hopper and the water box. A first material hole and a second material hole are respectively opened on the surface of the transmission rod at the position of the discharge pipe of the hopper and the water box. When the first material hole and the second material hole have not moved into the discharge pipe, the hopper and the water box stop feeding and draining. When the first material hole and the second material hole move into the discharge pipe, the slurry in the hopper and the water in the water box are discharged together into the feeding trough after being metered through the first material hole and the second material hole. This design can accurately control the addition of slurry and water, stabilize the ratio, reduce errors, significantly improve the sorting efficiency, and has good performance.

[0018] In this invention, the transmission rod innovatively integrates a first toothed section and a second toothed section, which respectively form a precise mesh with the drive gear and the external gear ring. This design breaks through the limitations of traditional single-function systems, achieving simultaneous adjustment of slope and stroke count while precisely controlling the slurry and water volume. The first toothed section drives the drive gear to rotate through precise meshing, and the rotation of the drive gear drives the lifting seat to move smoothly, achieving stepless adjustment of the bed slope. The second toothed section precisely drives the external gear ring to rotate, which in turn drives the potentiometer speed control knob to rotate synchronously, precisely adjusting the main motor speed and achieving precise control of the stroke count. The overall design of the device has a high degree of integration, is easy to operate, and the single drive of the electric telescopic rod facilitates unified control, avoids repeated debugging, significantly reduces operational complexity, and has good performance.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Reference Figures 1-3 The ore sorting shaking table structure shown includes a base 1, a bed surface 2, a transmission mechanism 3, and a main motor 4, and also includes:

[0029] Plate frame 5: driven by transmission mechanism 3 to achieve horizontal reciprocating movement on top of machine base 1, and bed surface 2 is set on plate frame 5;

[0030] Lifting seat 6: Driven by a drive gear 61 set on the side plate surface of the machine base 1, it can be vertically lifted and lowered at the top of the machine base 1. The lifting seat 6 is used to adjust the slope of the bed surface 2.

[0031] Hopper 7 and water box 8 are sequentially arranged on the surface of the side plate of the machine base 1;

[0032] Transmission rod 10: Driven by an electric telescopic rod 11 set on the side plate surface of the base 1, it can move horizontally back and forth on the inner wall of the discharge pipe of the hopper 7 and the water box 8. The transmission rod 10 has a first material hole 101 and a second material hole 102 respectively at the corresponding positions of the two sets of discharge pipes. The transmission rod 10 has a first tooth 103 and a second tooth 104 respectively at the corresponding positions of the outer gear ring 42 on the surface of the drive gear 61 and the potentiometer speed adjustment knob 41 in the main motor 4, and they are meshed and connected.

[0033] Controller 9: It is installed on the side plate of the base 1 and is connected to the main motor 4 and the electric telescopic rod 11 respectively.

[0034] It should be noted that, in this embodiment, the base 1 and the tailings end and concentrate end of the bed 2 are respectively provided with receiving hoppers.

[0035] It should be noted that the bed surface 2 described in this embodiment is prior art, and therefore will not be elaborated upon here.

[0036] It should be noted that the hopper 7 and water box 8 described in this embodiment correspond to the positions of the feeding trough 23 on the bed surface 2. A discharge trough is provided on one side of the feeding trough 23, and regulating valves are evenly arranged on the inner wall of the discharge trough.

[0037] It should be noted that the transmission mechanism 3 described in this embodiment is an eccentric linkage transmission mechanism. The connecting seat in the eccentric linkage transmission mechanism is connected to one end surface of the plate frame 5, and the large pulley in the eccentric linkage transmission mechanism is connected to the small pulley on the main motor 4 through the transmission belt.

[0038] It should be noted that the controller 9 described in this embodiment is electrically connected to an external power supply.

[0039] It should be noted that a sealing ring is provided on the transmission rod 10 described in this embodiment.

[0040] Specifically, the present invention has a reasonable structure. It includes a hopper 7, a water box 8, and a transmission rod 10. The transmission rod 10 is horizontally slidably connected to the inner wall of the discharge pipe of the hopper 7 and the water box 8. A first material hole 101 and a second material hole 102 are respectively opened on the surface of the transmission rod 10 at the positions of the discharge pipes of the hopper 7 and the water box 8. When the first material hole 101 and the second material hole 102 are not inside the discharge pipe, the hopper 7 and the water box 8 stop discharging and draining. When the first material hole 101 and the second material hole 102 are inside the discharge pipe, the slurry in the hopper 7 and the water in the water box 8 are quantitatively discharged together into the feed trough 23 (set on the bed surface) after passing through the first material hole 101 and the second material hole 102. This design can precisely control the addition of slurry and water, stabilize the ratio, reduce errors, significantly improve separation efficiency, and has good performance. The transmission rod 10 of the present invention innovatively integrates a first toothed part 103 and a second toothed part 104. The first tooth 103 precisely meshes with the drive gear 61 and the external gear ring 42, breaking through the limitations of traditional single-function designs. While precisely controlling the slurry and water volume, it simultaneously adjusts the slope and stroke count. The first tooth 103 drives the drive gear 61 to rotate through precise meshing, which in turn drives the lifting seat 6 to move smoothly, achieving stepless adjustment of the bed surface 2's slope. The second tooth 104 precisely drives the external gear ring 42 to rotate, which in turn drives the potentiometer speed control knob 41 to rotate synchronously, precisely adjusting the main motor 4's speed and achieving precise control of the stroke count. The device has a high degree of integration and is easy to operate. The single drive of the electric telescopic rod 11 facilitates unified control, avoiding repeated adjustments and significantly reducing operational complexity, resulting in good performance. The operation of this device is uniformly controlled by the controller 9, requiring no manual intervention. This not only reduces the possibility of human error but also improves the continuity and stability of the sorting process.

[0041] As a preferred embodiment of this example, Figure 2 As shown, one end of the bed surface 2 is hinged to the top of one end of the frame 5. A spring 21 is fixedly connected between the bottom of the other end of the bed surface 2 and the top of the other end of the frame 5. Rollers 22 and through grooves 51 are respectively provided at the bottom of the bed surface 2 and the surface of the frame 5 corresponding to the position of the lifting seat 6. The lifting seat 6 is located inside the through groove 51. A guide groove is opened at the top of the lifting seat 6 corresponding to the position of the roller 22. The roller 22 is located in the guide groove and is slidably connected to the inner wall of the guide groove.

[0042] It should be noted that the length of the through groove 51 described in this embodiment is greater than the length of the lifting seat 6. This arrangement ensures that when the plate frame 5 moves horizontally back and forth, its movement trajectory does not interfere with the structural space of the lifting seat 6, thereby avoiding structural conflicts.

[0043] Specifically, one bottom end of the bed surface 2 is hinged to the top end of the frame 5. This connection allows the bed surface 2 to rotate around the hinge point at a certain angle, providing a basis for subsequent lifting and tilting movements. The other bottom end of the bed surface 2 is elastically connected to the corresponding top end of the frame 5 via a spring 21. The spring 21 provides a downward pulling force to keep the bed surface 2 stable during lifting or tilting. Rollers 22 are located at the bottom of the bed surface 2, corresponding to the position of the lifting seat 6. The rollers 22 reduce friction between the bed surface 2 and the lifting seat 6, ensuring the bed surface 2... The lifting and tilting movements are smoother. The guide groove is opened at the top of the lifting seat 6, corresponding to the position of the roller 22. The roller 22 is precisely embedded in the guide groove and can slide smoothly along the inner wall of the guide groove. The sliding connection between the roller 22 and the inner wall of the guide groove allows the bed surface 2 to move along the trajectory of the guide groove during lifting or tilting, ensuring the accuracy and stability of the movement. The lifting seat 6 is located inside the through groove 51 on the surface of the plate frame 5. This design ensures that when the plate frame 5 moves horizontally back and forth, its movement trajectory does not interfere with the structural space of the lifting seat 6, thereby avoiding structural conflicts.

[0044] As a preferred embodiment of this example, Figure 3 As shown, a column groove is provided at the top of the base 1 corresponding to the position of the lifting seat 6, and a reciprocating screw 62 is threadedly connected to the inner wall of the column groove. The lifting seat 6 is threadedly connected to the outer surface of the reciprocating screw 62 and vertically slidably connected to the inner wall of the column groove. One end of the reciprocating screw 62 passes through the interior of the base 1 and is fixedly connected to a first bevel gear 63. A second bevel gear 64 is rotatably connected to one side of the first bevel gear 63 and they mesh with each other. A synchronous gear 65 is provided at the corresponding position of the surface of the central shaft of the second bevel gear 64 and the surface of the drive gear 61, and they are connected by a synchronous toothed belt 66.

[0045] It should be noted that the top of the base 1 described in this embodiment has a slot to facilitate the synchronous toothed belt 66 to pass through into the interior of the base 1.

[0046] Specifically, by driving the gear 61 to rotate, the synchronous gear 65 and the synchronous toothed belt 66 are driven to rotate, which in turn drives the second bevel gear 64 to rotate. The rotation of the second bevel gear 64 drives the first bevel gear 63 to rotate, which in turn drives the reciprocating screw 62 to rotate. The rotation of the reciprocating screw 62 causes the lifting seat 6 to move vertically back and forth in the column groove. The vertical lifting of the lifting seat 6 synchronously changes the height of one end of the bed surface 2, thereby realizing the slope adjustment.

[0047] The reciprocating screw 62 is designed to enable the lifting seat 6 to automatically adjust to large and small angles under unidirectional drive.

[0048] For example: parameters corresponding to coarse-grained grade: low slurry flow (1.0 L / s) + low water flow (1.5 L / s) + large angle (4°) + low stroke (200 strokes / minute);

[0049] Parameters corresponding to fine-grained particles: high slurry flow (1.8 L / s) + high water flow (2.2 L / s) + small angle (2°) + high stroke (280 strokes / minute);

[0050] The maximum adjustment angle of the bed surface 2 is set to 4° and the minimum to 0°. In the initial state, the lifting seat 6 is located in the middle position of the reciprocating screw 62, that is, the angle of the bed surface 2 is 2°. When the coarse grain state is reached, the reciprocating screw 62 rotates in one direction to move the lifting seat 6 to the upper position, that is, the angle of the bed surface 2 is 4°. When the fine grain state is reached, the reciprocating screw 62 rotates in one direction again to move the lifting seat 6 from the upper position back to the middle position, that is, the angle of the bed surface 2 is adjusted from 4° to 2°.

[0051] As a preferred embodiment of this example, Figure 4 As shown, both the first material hole 101 and the second material hole 102 are funnel-shaped. There are two sets of the first material hole 101 and the second material hole 102. The spacing between the two sets of first material holes 101 is the same as the spacing between the two sets of second material holes 102. The internal space of the first material hole 101 on the side closer to the electric telescopic rod 11 is smaller than the internal space of the first material hole 101 on the side farther from the electric telescopic rod 11. The internal space of the second material hole 102 on the side closer to the electric telescopic rod 11 is smaller than the internal space of the second material hole 102 on the side farther from the electric telescopic rod 11.

[0052] Specifically, the quantity and internal space of the first material hole 101 and the second material hole 102 are further explained. The first material hole 101 and the second material hole 102 are both set in two groups, which are used to adapt to two different working conditions of coarse and fine particle size, respectively. The spacing between the two groups of first material holes 101 is the same as the spacing between the two groups of second material holes 102, so as to ensure the stability of the moving value during the material hole switching process.

[0053] In terms of internal space design, the internal space of the first material hole 101 on the side closer to the electric telescopic rod 11 is smaller than the internal space of the first material hole 101 on the side farther from the electric telescopic rod 11. Similarly, the internal space of the second material hole 102 on the side closer to the electric telescopic rod 11 is also smaller than the internal space of the second material hole 102 on the side farther from the electric telescopic rod 11. This design cleverly realizes that as the particle size of the ore changes from coarse to fine, the amount of slurry and water can be automatically adjusted to a suitable total amount, effectively improving the use effect of the equipment.

[0054] For example: parameters corresponding to coarse-grained grade: low slurry flow (1.0 L / s) + low water flow (1.5 L / s) + large angle (4°) + low stroke (200 strokes / minute);

[0055] Parameters corresponding to fine-grained particles: high slurry flow (1.8 L / s) + high water flow (2.2 L / s) + small angle (2°) + high stroke (280 strokes / minute);

[0056] The internal spaces of the first feed hole 101 and the second feed hole 102 on the side closest to the electric telescopic rod 11 correspond to the parameters corresponding to the coarse particle size, namely, slurry volume 1.0 L / s and water volume 1.5 L / s. The internal spaces of the first feed hole 101 and the second feed hole 102 on the side furthest from the electric telescopic rod 11, plus the internal spaces of the first feed hole 101 and the second feed hole 102 on the side closest to the electric telescopic rod 11, correspond to the parameters corresponding to the fine particle size, namely, slurry volume 1.0 L / s + slurry volume 0.8 L / s = slurry volume 1.8 L / s, water volume 1.5 L / s + water volume 0.7 L / s = water volume 2.2 L / s.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
