Description

Technical Field

[0001] The present invention relates to the technical field of ore dressing shaking tables, and particularly to a shaking table device for improving the separation efficiency. Background Art

[0002] In the field of mineral resource development and utilization, the separation technology is the core link to improve the ore grade and resource utilization rate. As a classic mineral separation equipment, the shaking table is widely used in the ore dressing 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, realizes the effective separation of different minerals by simulating the synergistic action of the natural gravity field and the water flow dynamic field and using the movement differences of mineral particles on the bed surface. It has long been the key tool to solve the problem of mineral separation.

[0003] However, with the continuous deepening of mineral resource exploitation and the continuous improvement of ore dressing technology requirements, traditional separation equipment such as the 6S shaking table has gradually revealed many problems that cannot be ignored in practical applications. In particular, the problem of low separation efficiency has become the main bottleneck restricting the improvement of ore dressing efficiency and resource recovery rate.

[0004] Specifically, the deficiencies of the current 6S shaking table in terms of separation efficiency are mainly reflected in the following two aspects: First, the pulp addition method is backward. During the operation of the 6S shaking table, the addition of pulp mainly depends on manual operation. This method not only has a large labor intensity but also is difficult to accurately control the addition amount of pulp, resulting in the ratio of pulp to water often deviating from the optimal matching range. The fluctuation of pulp concentration will directly affect the movement state and separation effect of mineral particles on the bed surface. Too thick pulp will hinder the movement of mineral particles and make it difficult to fully stratify, while too thin pulp will make the mineral particles move too dispersedly, resulting in a decrease in separation accuracy and efficiency, and at the same time increasing the difficulty and cost of subsequent processing. Second, the particle size detection and regulation are lacking. The particle size of mineral particles in the pulp plays a decisive role in the separation effect. Mineral particles with different particle sizes have different movement trajectories and residence times on the shaking table. Therefore, it is necessary to finely adjust parameters such as pulp amount, water amount, slope, and stroke times according to the particle size to achieve the best separation effect. However, the existing 6S shaking tables generally lack a real-time monitoring and regulation mechanism for the particle size of pulp and cannot dynamically adjust the separation conditions according to the particle size change, resulting in unstable separation effects and difficult to improve the resource recovery rate. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems in the related technologies to a certain extent.

[0006] To this end, the object of the present invention is to provide a shaking table device that improves the sorting efficiency. The structure of the present invention is reasonable, which can accurately control the addition of pulp, stabilize the proportion, reduce errors, and improve the sorting efficiency. At the same time, it also monitors the particle size in real time and dynamically adjusts the parameters, flexibly adapts to the changes in ore, realizes effective separation, further improves the sorting efficiency, and its automated design reduces labor, reduces intensity, and improves safety.

[0007] To achieve the above object, the present invention provides a shaking table device that improves the sorting efficiency, including a machine base, a table surface, a transmission mechanism, and a main motor, and further includes: Plate frame: Driven by the transmission mechanism to achieve horizontal reciprocating movement on the top of the machine base, and the table surface is arranged on the plate frame; Lifting seat: Driven by a driving gear arranged on the surface of the side plate of the machine base to achieve vertical lifting on the top of the machine base, and the lifting seat is used to adjust the slope of the table surface; Hopper and water box: Sequentially arranged on the surface of the side plate of the machine base, and a detection box is arranged on the surface of the hopper for detecting the liquid level, flow rate, and particle size of the pulp inside the hopper; Transmission rod: Driven by an electric telescopic rod arranged on the surface of the side plate of the machine base to achieve horizontal reciprocating movement on the inner wall of the discharge pipes of the hopper and the water box. First material holes and second material holes are respectively opened at positions corresponding to the two groups of discharge pipes on the surface of the transmission rod. First tooth parts and second tooth parts are respectively arranged at positions corresponding to the outer tooth rings on the surfaces of the driving gear and the potentiometer speed control knob of the main motor on the surface of the transmission rod, and are meshed and connected; Controller: Arranged on the surface of the side plate of the machine base and respectively connected to the main motor, the detection box, and the electric telescopic rod.

[0008] In addition, a shaking table device that improves the sorting efficiency proposed according to the above application may also have the following additional technical features: Specifically, one end of the bottom of the table surface is hinged and fixed to the top of one end of the plate frame, and a spring is fixedly connected between the other end of the bottom of the table surface and the top of the other end of the plate frame. Rollers and through grooves are respectively arranged at positions corresponding to the lifting seat on the bottom surface of the table surface and the surface of the plate frame. The lifting seat is located inside the through groove, and a guide groove is opened at a position corresponding to the roller on the top of the lifting seat. The roller is located in the guide groove and is slidably connected to the inner wall of the guide groove.

[0009] Specifically, a column groove is formed at a position corresponding to the top of the machine base and the lifting seat, and a reciprocating lead 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 lead screw and is vertically slidably connected to the inner wall of the column groove. One end of the reciprocating lead screw penetrates into the interior of the machine 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 meshes therewith. Synchronous gears are respectively arranged at positions corresponding to the surface of the central axis of the second bevel gear and the surface of the driving gear, and are connected by a synchronous toothed belt.

[0010] Specifically, the detection box includes a box body, and the box body is fixedly connected to the surface of the hopper. An ultrasonic particle size analyzer, a slurry type electromagnetic flowmeter and an ultrasonic liquid level sensor are sequentially arranged on the inner wall of the box body. The ultrasonic particle size analyzer, the slurry type electromagnetic flowmeter and the ultrasonic liquid level sensor are respectively connected to the controller through a bus system to realize data transmission and reception of control instructions.

[0011] Specifically, both the first material hole and the second material hole are funnel-shaped. Two groups are respectively provided for the number of the first material holes and the second material holes. The distance between the two groups of the first material holes is the same as the distance between the two groups 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. 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.

[0012] Specifically, the second tooth part includes a front tooth part and a rear tooth part. The external gear ring includes an internal tooth part and an external tooth part. The tooth module of the front tooth part is the same as that of the internal tooth part. The tooth module of the rear tooth part is the same as that of the external tooth part. The tooth module of the internal tooth part is larger than that of the external tooth part. When the second tooth part drives the external gear ring to rotate, the angle of rotation of the external gear ring driven by the meshing of the front tooth part and the internal tooth part is larger than the angle of rotation of the external gear ring driven by the meshing of the rear tooth part and the external tooth part.

[0015] Additional aspects and advantages of the present invention will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present invention.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The structure of the present invention is reasonable. The present invention is provided with a hopper, a water box and a transmission rod. Among them, the transmission rod is horizontally slidably connected to the inner walls of the discharge pipes of the hopper and the water box. First material holes and second material holes are respectively formed at the positions of the surface of the transmission rod and the discharge pipes of the hopper and the water box. When the first material hole and the second material hole do not move into the discharge pipe, the hopper and the water box stop discharging materials and draining water. When the first material hole and the second material hole move into the discharge pipe, the pulp in the hopper and the water in the water box are quantitatively discharged into the feeding trough through the first material hole and the second material hole. This design can accurately control the addition of pulp and water, stabilize the ratio, reduce errors, significantly improve the separation efficiency, and has good use effects. 2. The present invention is also provided with a detection box on the hopper. The detection box can detect key information such as the particle size distribution of the pulp, the flow rate of the slurry, and the liquid level height inside the hopper before separation, providing strong support for the optimization and adjustment of the production process. The controller can automatically adjust production parameters such as the pulp volume, water volume, slope, and stroke times according to the detection data, significantly improving the separation efficiency. 3. The transmission rod of the present invention innovatively integrates a first tooth part and a second tooth part, which are respectively in precise meshing with a driving gear and an external tooth ring. This design breaks through the traditional single-function limitation. While accurately controlling the pulp volume and water volume, it realizes the synchronous adjustment of the slope and stroke times. The first tooth part drives the driving gear to rotate through precise meshing, and the rotation of the driving gear drives the lifting seat to move smoothly, realizing stepless adjustment of the bed surface slope. The second tooth part precisely drives the external tooth ring to rotate, and then drives the potentiometer speed regulation knob to rotate synchronously, precisely adjusting the speed of the main motor and realizing precise control of the stroke times. The overall design of the device has a high degree of integration, convenient operation, and single driving of the electric telescopic rod is convenient for unified control, avoiding repeated debugging, significantly reducing the operation complexity, and having good use effects. 4. On the basis of stabilizing the pulp ratio and realizing particle size control, the present device innovatively integrates a y-ray densitometer and a sub-motor. The y-ray densitometer accurately detects the material density in real time, and the sub-motor automatically adjusts the stroke length according to the density difference, accurately matching the separation requirements of materials with different densities, effectively improving the separation efficiency, with simple operation and remarkable effects. 5. The operation of the present device is uniformly controlled by the controller, and the overall operation does not require manual intervention. This not only reduces the possibility of human operation errors, but also improves the continuity and stability of the separation process, enabling it to meet the requirements of modern concentrators for efficient, stable, and intelligent production.

[0020] The following describes a shaking table device for improving sorting efficiency according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0021] As Figures 1-8 shown, a shaking table device for improving sorting efficiency according to an embodiment of the present invention includes a machine base 1, a table surface 2, a transmission mechanism 3, and a main motor 4, and further includes: A plate frame 5: Driven by the transmission mechanism 3 to achieve horizontal reciprocating movement on the top of the machine base 1, and the table surface 2 is arranged on the plate frame 5; A lifting seat 6: Driven by a driving gear 61 arranged on the side surface of the machine base 1 to achieve vertical lifting on the top of the machine base 1, and the lifting seat 6 is used to adjust the slope of the table surface 2; A hopper 7 and a water box 8: Arranged in sequence on the side surface of the machine base 1, and a detection box 9 is arranged on the surface of the hopper 7 for detecting the liquid level, flow rate, and particle size of the pulp inside the hopper 7; A transmission rod 10: Driven by an electric telescopic rod 11 arranged on the side surface of the machine base 1 to achieve horizontal reciprocating movement on the inner wall of the discharge pipes of the hopper 7 and the water box 8. First material holes 101 and second material holes 102 are respectively opened at positions corresponding to the two groups of discharge pipes on the surface of the transmission rod 10. First tooth portions 103 and second tooth portions 104 are respectively arranged at positions corresponding to the outer tooth ring 42 on the surface of the driving gear 61 and the potentiometer speed control knob 41 on the main motor 4 on the surface of the transmission rod 10, and are engaged and connected; A controller 12: Arranged on the side surface of the machine base 1 and connected to the main motor 4, the detection box 9, and the electric telescopic rod 11 respectively.

[0022] It should be noted that receiving hoppers are respectively arranged at positions corresponding to the tailing end and the concentrate end of the table surface 2 on the surface of the machine base 1 described in this embodiment.

[0023] It should be noted that the table surface 2 described in this embodiment is a prior art and will not be elaborated herein.

[0024] It should be noted that the hopper 7 and the water box 8 described in this embodiment correspond to the feeding trough 23 on the table surface 2. A discharge trough is arranged on one side of the feeding trough 23, and regulating valves are uniformly arranged on the inner wall of the discharge trough.

[0025] It should be noted that the transmission mechanism 3 described in this embodiment is an eccentric connecting rod type transmission mechanism. The linkage seat in the eccentric connecting rod type transmission mechanism is connected to the surface of one end of the plate frame 5, and the large belt pulley in the eccentric connecting rod type transmission mechanism is connected to the small belt pulley on the main motor 4 through a transmission belt.

[0026] It should be noted that the controller 12 described in this embodiment is electrically connected to an external power supply.

[0027] It should be noted that a sealing ring is provided on the transmission rod 10 described in this embodiment.

[0028] Specifically, the structure of the present invention is reasonable. The present invention is provided with a hopper 7, a water box 8 and a transmission rod 10. Among them, the transmission rod 10 is horizontally slidably connected to the inner walls of the discharge pipes of the hopper 7 and the water box 8. First material holes 101 and second material holes 102 are respectively formed at the positions of the surface of the transmission rod 10 and the discharge pipes of the hopper 7 and the water box 8. When the first material holes 101 and the second material holes 102 do not move into the discharge pipes, the hopper 7 and the water box 8 stop discharging materials and draining water. When the first material holes 101 and the second material holes 102 move into the discharge pipes, the pulp in the hopper 7 and the water in the water box 8 are quantitatively discharged into the feeding trough 23 (provided on the table surface 2) through the first material holes 101 and the second material holes 102. This design can accurately control the addition of pulp and water, stabilize the ratio, reduce errors, and significantly improve the sorting efficiency, and has good use effects. The present invention is also provided with a detection box 9 on the hopper 7. The detection box 9 can detect key information such as the particle size distribution of the pulp, the flow rate of the slurry, and the liquid level height inside the hopper 7 before sorting, providing strong support for the optimization and adjustment of the production process. The controller 12 can automatically adjust production parameters such as the pulp volume, water volume, slope, and stroke frequency according to the detection data, significantly improving the sorting efficiency. The transmission rod 10 of the present invention innovatively integrates a first tooth part 103 and a second tooth part 104, which are respectively in precise meshing with the driving gear 61 and the external tooth ring 42. This design breaks through the traditional single-function limitation and realizes the synchronous adjustment of the slope and the stroke frequency while accurately controlling the pulp volume and the water volume. The first tooth part 103 drives the driving gear 61 to rotate through precise meshing, and the rotation of the driving gear 61 drives the lifting seat 6 to move smoothly, realizing stepless adjustment of the slope of the table surface 2. The second tooth part 104 precisely drives the external tooth ring 42 to rotate, and then drives the potentiometer speed regulation knob 41 to rotate synchronously, precisely adjusting the speed of the main motor 4 and realizing precise control of the stroke frequency. The overall design of the device has a high integration degree, is convenient to operate, and the single drive of the electric telescopic rod 11 is convenient for unified control, avoiding repeated debugging, significantly reducing the operation complexity, and having good use effects. The operation of this device is uniformly controlled by the controller 12, and the overall operation does not require manual intervention. This not only reduces the possibility of human operation errors, but also improves the continuity and stability of the sorting process, enabling it to meet the requirements of modern ore dressing plants for efficient, stable, and intelligent production.

[0029] In an embodiment of the present invention, as Figure 2 shown, one end bottom of the bed surface 2 is hinged and fixed to the top of one end of the plate frame 5, and a spring 21 is fixedly connected between the other end bottom of the bed surface 2 and the top of the other end of the plate frame 5. At positions corresponding to the lifting seat 6 on the bottom surface of the bed surface 2 and the surface of the plate frame 5, a roller 22 and a through groove 51 are respectively provided. The lifting seat 6 is located inside the through groove 51. At a position corresponding to the roller 22 on the top of the lifting seat 6, a guide groove is provided. The roller 22 is located in the guide groove and is slidably connected to the inner wall of the guide groove.

[0030] 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. Such a setting can ensure that when the plate frame 5 makes a horizontal reciprocating movement, its movement trajectory does not interfere with the structural space of the lifting seat 6, thereby avoiding structural conflicts.

[0031] Specifically, one end bottom of the bed surface 2 is fixed to the top of one end of the plate frame 5 by a hinge connection. This connection method allows the bed surface 2 to rotate by a certain angle around the hinge point, providing a basis for subsequent lifting and tilting actions. The other end bottom of the bed surface 2 and the corresponding end top of the plate frame 5 are elastically connected by a spring 21. The function of the spring 21 is to provide a downward pulling force to keep the bed surface 2 stable during the lifting or tilting process. The roller 22 is provided at the bottom of the bed surface 2, corresponding to the position of the lifting seat 6. The function of the roller 22 is to reduce the friction between the bed surface 2 and the lifting seat 6, making the lifting and tilting actions of the bed surface 2 smoother. The guide groove is provided at the top of the lifting seat 6, at a position corresponding to the roller 22. The roller 22 just fits into the guide groove and can smoothly slide along the inner wall of the guide groove. The sliding connection between the roller 22 and the inner wall of the guide groove enables the bed surface 2 to move along the trajectory of the guide groove during the lifting or tilting process, ensuring the accuracy and stability of the action. The lifting seat 6 is located inside the through groove 51 on the surface of the plate frame 5. This design makes the movement trajectory of the plate frame 5 not interfere with the structural space of the lifting seat 6 when the plate frame 5 makes a horizontal reciprocating movement, thereby avoiding structural conflicts.

[0032] In an embodiment of the present invention, as Figure 2 shown, a column groove is provided at the position corresponding to the lifting seat 6 on the top of the machine base 1, and a reciprocating lead 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 lead screw 62 and is vertically slidably connected to the inner wall of the column groove. One end of the reciprocating lead screw 62 penetrates into the interior of the machine 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 is meshed therewith. Synchronous gears 65 are respectively provided at positions corresponding to the surface of the central axis end of the second bevel gear 64 and the surface of the driving gear 61, and are connected by a synchronous toothed belt 66.

[0033] It should be noted that a notch is provided at the top of the machine base 1 described in this embodiment to facilitate the penetration of the synchronous belt 66 into the interior of the machine base 1.

[0034] Specifically, by rotating the driving gear 61, the synchronous gear 65 and the synchronous belt 66 are driven to rotate, thereby driving the second bevel gear 64 to rotate. The rotation of the second bevel gear 64 drives the first bevel gear 63 to rotate, and finally drives the reciprocating lead screw 62 to rotate. The rotation of the reciprocating lead screw 62 causes the lifting seat 6 to perform reciprocating movement in the vertical direction within 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 slope adjustment.

[0035] Among them, the reciprocating lead screw 62 is designed to be able to drive the lifting seat 6 to automatically adjust to large and small angles under one-way drive.

[0036] For example: Coarse particle size corresponding parameters: low pulp volume (1.0 L / s) + low water volume (1.5 L / s) + large angle (4°) + low stroke (200 times / minute); Fine particle size corresponding parameters: high pulp volume (1.8 L / s) + high water volume (2.2 L / s) + small angle (2°) + high stroke (280 times / minute); It is set that the maximum adjustment angle of the bed surface 2 is 4° and the minimum is 0°. In the initial state, the lifting seat 6 is located at the middle position of the reciprocating lead screw 62, that is, driving the angle of the bed surface 2 to be 2°. When in the coarse particle state, the reciprocating lead screw 62 rotates in one direction to drive the lifting seat 6 to move to the upper end position, that is, driving the angle of the bed surface 2 to be 4°. When in the fine particle state, the reciprocating lead screw 62 rotates in one direction again to drive the lifting seat 6 to move from the upper end position back to the middle position, that is, the angle of the bed surface 2 is adjusted from 4° to 2°.

[0037] In an embodiment of the present invention, as Figure 5 shown, the detection box 9 includes a box body 91. The box body 91 is fixedly connected to the surface of the hopper 7. An ultrasonic particle size analyzer 92, a slurry type electromagnetic flowmeter 93, and an ultrasonic liquid level sensor 94 are sequentially arranged on the inner wall of the box body 91. The ultrasonic particle size analyzer 92, the slurry type electromagnetic flowmeter 93, and the ultrasonic liquid level sensor 94 are respectively connected to the controller 12 through a bus system to realize data transmission and receipt of control instructions.

[0038] It should be noted that holes, cavities, and grooves for facilitating detection are respectively provided on the surfaces of the box body 91 and the hopper 7 described in this embodiment.

[0039] Specifically, the main body of the detection box 9 is the box body 91, which is fixedly connected to the surface of the hopper 7. The design of the box body 91 aims to accommodate and protect the internal detection equipment while facilitating integration with the hopper 7. The main body of the ultrasonic particle size analyzer 92 is arranged on the inner wall of the box body 91 and is used to monitor the particle size distribution of the material in the hopper 7 in real time. Through ultrasonic technology, this equipment can accurately analyze the size and distribution of material particles, providing key data support for subsequent material processing. The main body of the slurry electromagnetic flowmeter 93 is also arranged on the inner wall of the box body 91 and is used to measure the flow rate of the slurry in the hopper 7. Through the principle of electromagnetic induction, this equipment can accurately measure the flow velocity and flow rate of the slurry, providing an important basis for flow control in the production process. The main body of the ultrasonic liquid level sensor 94 is also installed on the inner wall of the box body 91 and is used to monitor the liquid level height of the liquid in the hopper 7 in real time. Through the principle of ultrasonic reflection, this equipment can accurately measure the liquid level, ensuring that the material quantity in the hopper 7 is within a safe and controllable range. Through the bus system, the detection equipment can transmit the collected data to the controller 12 in real time for the controller 12 to analyze and process. These data include key information such as the particle size distribution of the material, the flow rate of the slurry, and the liquid level height of the liquid, providing strong support for the optimization and adjustment of the production process. The controller 12 can automatically adjust production parameters such as the pulp quantity, water quantity, slope, and stroke times according to the detection data, significantly improving the separation efficiency.

[0040] In an embodiment of the present invention, as Figure 4 shown, both the first material hole 101 and the second material hole 102 are funnel-shaped. The number of the first material holes 101 and the second material holes 102 are each set to two groups. The distance between the two groups of first material holes 101 is the same as the distance between the two groups of second material holes 102. The internal space of the first material hole 101 closer to the electric telescopic rod 11 is smaller than the internal space of the first material hole 101 farther from the electric telescopic rod 11. The internal space of the second material hole 102 closer to the electric telescopic rod 11 is smaller than the internal space of the second material hole 102 farther from the electric telescopic rod 11.

[0041] Specifically, further explain the number and internal space of the first material hole 101 and the second material hole 102. The first material hole 101 and the second material hole 102 are both set to two groups, respectively used to adapt to two different working conditions of coarse particle size and fine particle size. The distance between the two groups of first material holes 101 is the same as the distance 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.

[0042] In terms of the internal space design, the internal space of the first material hole 101 on the side close to the electric telescopic rod 11 is smaller than that of the first material hole 101 on the side far from the electric telescopic rod 11. Similarly, the internal space of the second material hole 102 on the side close to the electric telescopic rod 11 is also smaller than that of the second material hole 102 on the side far from the electric telescopic rod 11. This design cleverly realizes that as the particle size of the ore changes from coarse to fine, the total amount of pulp and water can be automatically adjusted to an appropriate total amount, effectively improving the use effect of the equipment.

[0043] For example: Coarse particle size corresponding parameters: low pulp volume (1.0 L / s) + low water volume (1.5 L / s) + large angle (4°) + low stroke (200 times / minute); Fine particle size corresponding parameters: high pulp volume (1.8 L / s) + high water volume (2.2 L / s) + small angle (2°) + high stroke (280 times / minute); The internal spaces of the first material hole 101 on the side close to the electric telescopic rod 11 and the second material hole 102 on the side close to the electric telescopic rod 11 respectively correspond to the parameters for the coarse particle size, that is, the pulp volume is 1.0 L / s and the water volume is 1.5 L / s. The internal space of the first material hole 101 on the side far from the electric telescopic rod 11 and the internal space of the second material hole 102 on the side far from the electric telescopic rod 11 plus the internal spaces of the first material hole 101 on the side close to the electric telescopic rod 11 and the second material hole 102 on the side close to the electric telescopic rod 11 respectively correspond to the parameters for the fine particle size, that is, pulp volume 1.0 L / s + pulp volume 0.8 L / s = pulp volume 1.8 L / s, water volume 1.5 L / s + water volume 0.7 L / s = water volume 2.2 L / s.

[0044] In an embodiment of the present invention, as Figure 6 shown, the second tooth part 104 includes a front tooth part 1041 and a rear tooth part 1042. The outer tooth ring 42 includes an inner tooth part 421 and an outer tooth part 422. The tooth module of the front tooth part 1041 is the same as that of the inner tooth part 421, and the tooth module of the rear tooth part 1042 is the same as that of the outer tooth part 422. The tooth module of the inner tooth part 421 is greater than that of the outer tooth part 422. When the second tooth part 104 drives the outer tooth ring 42 to rotate, the angle by which the outer tooth ring 42 is driven to rotate when the front tooth part 1041 meshes with the inner tooth part 421 is greater than the angle by which the outer tooth ring 42 is driven to rotate when the rear tooth part 1042 meshes with the outer tooth part 422.

[0045] Specifically, when the particle size changes from coarse to fine, the number of stroke times will increase accordingly.

[0046] For example: Coarse particle size corresponding parameters: low pulp volume (1.0 L / s) + low water volume (1.5 L / s) + large angle (4°) + low stroke (200 times / minute); Fine-grained corresponding parameters: high pulp volume (1.8 L / s) + high water volume (2.2 L / s) + small angle (2°) + high stroke (280 times / minute).

[0047] To ensure that the rotation angles of the outer gear ring 42 driven by the second tooth part 104 are different under the same moving distance, the front tooth part 1041, the rear tooth part 1042, the inner tooth part 421 and the outer tooth part 422 are specially set. Since the tooth module of the inner tooth part 421 is larger than that of the outer tooth part 422, under the condition of the same number of teeth, the tooth pitch of the inner tooth part 421 is larger, that is, the central angle corresponding to each rotation of a tooth is larger. When the second tooth part 104 drives the outer gear ring 42 to rotate, the front tooth part 1041 meshes with the inner tooth part 421. Due to the large tooth pitch of the inner tooth part 421, the rotation angle of the driven outer gear ring 42 will be relatively large; while the rear tooth part 1042 meshes with the outer tooth part 422, and the tooth pitch of the outer tooth part 422 is small, so the rotation angle of the driven outer gear ring 42 is relatively small. This makes it easy for the outer gear ring 42 to drive the potentiometer speed control knob 41 to rotate to 200 times / minute in the early stage, and also makes it easy for the outer gear ring 42 to drive the potentiometer speed control knob 41 to rotate to 280 times / minute in the later stage. The operation is simple and the use effect is good.

[0048] In an embodiment of the present invention, as Figure 5 shown, a γ-ray densitometer 95 is provided on the inner wall of the detection box 9 and is located between the ultrasonic particle size analyzer 92 and the slurry type electromagnetic flowmeter 93. The γ-ray densitometer 95 is used to detect the density of the pulp in the hopper 7. The γ-ray densitometer 95 is connected to the controller 12 through a bus system to realize data transmission and receipt of control instructions.

[0049] Specifically, to further improve the separation efficiency, a γ-ray densitometer 95 is specially provided in this device. The γ-ray densitometer 95 is used to detect the density of the pulp in the hopper 7. By analyzing the detection results and adjusting the stroke length according to the size of the density difference, the separation effect can be further improved. Generally speaking, when the γ-ray densitometer 95 detects a large density difference, it indicates that the stratification of minerals with different densities is not obvious enough. At this time, the adjusting rod 31 can be turned to change the stroke length of the bed surface 2 and shorten it to 80 mm, so that the mineral particles move quickly on the bed surface 2, reducing the situation where light minerals are entrained by heavy minerals, which is beneficial to quickly separating heavy minerals. When the γ-ray densitometer 95 detects a small density difference, it indicates that the stratification effect of the mineral particles is good, but the separation efficiency needs to be further enhanced. At this time, the adjusting rod 31 can be turned to change the stroke length of the bed surface 2 and increase it to 120 mm, extending the residence time of the minerals on the bed surface 2, so that the mineral particles have enough time for stratification and diffusion, enhancing the separation efficiency of density differences and improving the separation accuracy.

[0050] Among them, a long stroke is adopted in the case of coarse particles with a small density difference to enhance stratification, and a short stroke is adopted in the case of coarse particles with a large density difference to quickly separate heavy minerals and reduce the entrainment of light minerals.

[0051] A short stroke is adopted in the case of fine particles with a large density difference for rapid separation, and a long stroke is adopted in the case of fine particles with a small density difference to extend the residence time of minerals on the table 2 and enhance the separation efficiency of density differences.

[0052] In an embodiment of the present invention, as Figure 7 shown, a secondary motor 13 is provided at the top of the transmission mechanism 3. The output end of the secondary motor 13 is connected to the adjusting rod 31 in the transmission mechanism 3. The secondary motor 13 is connected to the controller 12 through a bus system to achieve data transmission and receipt of control instructions.

[0053] It should be noted that an encoder (not shown in the figure) is provided on the surface of the secondary motor 13 described in this embodiment and is connected to the controller 12 through a bus system to achieve data transmission and receipt of control instructions. The encoder is used to detect the number of rotation cycles of the secondary motor 13 in real time. The controller 12 determines the number of rotation cycles of the adjusting rod 31 based on the number of rotation cycles of the secondary motor 13 and judges the stroke length of the table 2 according to the number of rotation cycles of the adjusting rod 31.

[0054] It can be understood that the stroke length of the table 2 can be changed by driving the adjusting rod 31 to rotate. This is prior art and will not be elaborated here.

[0055] Specifically, the present device uses the controller 12 to precisely control the operation of the secondary motor 13. When the controller 12 issues an instruction, the secondary motor 13 starts and drives the adjusting rod 31 to rotate. The rotational movement of the adjusting rod 31 can synchronously change the stroke length of the table 2.

[0056] This design has many significant advantages. On the one hand, it successfully realizes the automatic control of the adjustment process, effectively replaces the traditional manual operation mode, and greatly improves the operation efficiency. On the other hand, through the unified centralized control of the controller 12, the entire adjustment process is simple and convenient to operate, and at the same time ensures the adjustment accuracy, showing excellent use effects in practical applications.

[0057] In summary, for a shaking table device for improving the sorting efficiency in the embodiment of the present invention, the structure of the present invention is reasonable, which can accurately control the addition of pulp, stabilize the ratio, reduce errors, and improve the sorting efficiency; at the same time, it also real-time monitors the particle size and dynamically adjusts the parameters, flexibly adapts to the changes of ores, realizes effective separation, further improves the sorting efficiency, and its automated design reduces labor, reduces intensity, and improves safety.
