[0002] In the existing ore screening, the ore is first fed into the sorting device through a vertical annular feeding device, and then the superior ore and the inferior ore are distinguished and stored separately by the laser in the sorting device. Specifically, the vertical annular feeding device includes: A housing, provided above the sorting device, with a feed inlet provided above the housing and a discharge outlet provided below the housing and communicating with the sorting device.

[0003] In the actual use process, it is found that after the ore enters the sorting device through the feed inlet and the discharge outlet, it directly accumulates at the central position of the sorting device, resulting in a situation where there is more ore in the center of the sorting device and less ore at the edge, making the feeding uneven, so that the characteristics of the inferior ore are not recognized by the sorting device and enter the storage area of the superior ore, resulting in a reduction in the yield of the superior ore.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] The following combines Figures 1 to 15 to describe the embodiments of the present invention.

[0028] According to an embodiment of the present invention, in a first aspect, a vertical annular material distribution device is provided, including: Base 1.

[0029] The material cylinder 2 is of a vertical structure. The material cylinder 2 is rotatably connected to the base 1. A material distribution channel 201 is provided inside the material cylinder 2 to make the material cylinder 2 an annular structure. One end of the material distribution channel 201 is a material inlet 2011, and the other end of the material distribution channel 201 is a material outlet 2012. The material cylinder 2 is used to transport materials.

[0030] The guiding unit 3 is arranged on the inner wall of the material distribution channel 201 and is used to guide the transmission direction of the materials.

[0031] In the vertical annular material distribution device of this embodiment, by setting the guiding unit 3 and the material cylinder 2 rotatably connected to the base 1, the materials entering the material cylinder 2 through the material inlet 2011 are such that part of the materials are transported along the guiding unit 3 and, in cooperation with the rotation of the material cylinder 2, the materials on the guiding unit 3 diffuse towards the edge of the material cylinder 2 under the action of centrifugal force. Another part of the materials is transported through the material distribution channel 201 where the guiding unit 3 is not provided, that is, this part of the materials is transported through the central position of the material cylinder 2. Based on this, the materials can be distributed both through the central position of the material cylinder 2 and at the edge position of the material cylinder 2, achieving dead - angle - free material distribution, thereby achieving the technical effect of improving the uniformity of material distribution.

[0032] Furthermore, since the material cylinder 2 is rotatably connected to the base 1, the materials passing through the material outlet 2012 are always under the action of an external force, avoiding the occurrence of material blockage, and thus achieving the technical effect of improving the material distribution efficiency of the vertical annular material distribution device. At the same time, the vertical annular material distribution device is small in volume, achieving the technical effect of saving the processing cost of the vertical annular material distribution device.

[0033] Among them, in this embodiment, the material is a mixture of high-quality ore and low-quality ore. Of course, in other embodiments, according to the different usage scenarios of the vertical annular feeding device, the type of the material is adjusted.

[0034] In addition, as shown in Figure 1 In this embodiment, through the feeding channel 201, the material cylinder 2 is of an annular structure, and the top end of the feeding channel 201 is the feeding port 2011, and the bottom end of the feeding channel 201 is the discharging port 2012, so that the material cylinder 2 is of a vertical structure.

[0035] Of course, in other embodiments, according to the different designs of the vertical annular feeding device, the structure of the material cylinder 2 and the positions of the feeding port 2011 and the discharging port 2012 are adjusted.

[0036] In addition, as shown in Figure 2 In this embodiment, the guiding unit 3 is an arc-shaped block. One end of the guiding unit 3 is close to the feeding port 2011, and the other end of the guiding unit 3 is close to the discharging port 2012, that is, the heights of the arc-shaped block along the Figure 4 vertical direction shown are different. Based on this, with the cooperation of the rotation of the material cylinder 2, the material arranged on the guiding unit 3 can rotate to have a centrifugal force, so that this part of the material can be transmitted along the edge of the material cylinder 2 and has a tendency to spread outwards, thereby increasing the amount of the material transmitted at the edge position of the material cylinder 2, avoiding the material being only arranged at the center position of the feeding, and further achieving the technical effect of improving the feeding uniformity of the vertical annular feeding device.

[0037] Among them, as shown in Figure 2 In this embodiment, there are multiple guiding units 3. Based on this, the connection points between the guiding unit 3 and the material can be increased, ensuring that the material falling on the guiding unit 3 is always affected by the centrifugal force, thereby achieving the technical effect of improving the reliability of the material feeding along the edge position of the material cylinder 2. Among them, in this embodiment, the number of the guiding units 3 is not limited too much.

[0038] Specifically, along the direction parallel to the axis of the material cylinder 2, the adjacent guiding units 3 are arranged at intervals, used for cutting the material cylinder 2 along the direction parallel to the axis of the material cylinder 2, and the cutting position is arranged between the guiding unit 3 closest to the feeding port 2011 and the guiding unit 3 closest to the discharging port 2012, and the cut material cylinder 2 is unfolded to form a plane, and the heights of the multiple guiding units 3 in the plane gradually decrease, and the inclination directions of the multiple guiding units 3 in the plane are the same.

[0039] For example, when the cartridge 2 is unfolded along the cutting position, in the direction from the inlet 2011 to the outlet 2012, the guiding units 3 are respectively the first guiding unit, the second guiding unit, and the third guiding unit. Between the first guiding unit and the second guiding unit, and between the second guiding unit and the third guiding unit, there are overlapping positions along the direction parallel to the axis of the cartridge 2, so that the material passes through the first guiding unit, enters the second guiding unit, and further leaves through the third guiding unit from the outlet 2012, thereby improving the reliability of the material rotating with the cartridge 2, avoiding the situation where the material is only at the central position of the housing in the related art, and thus achieving the technical effect of improving the uniformity of the material distribution.

[0040] As a transformable embodiment, it can also be that the guiding unit 3 is an arc-shaped piece, and any shape that can realize guiding the material transmission direction is within the protection scope of the present invention.

[0041] Of course, in other embodiments, according to the different designs of the vertical annular material distribution device, the shape of the guiding unit 3 and the positions of multiple guiding units 3 are adjusted.

[0042] In other embodiments, according to the different designs of the vertical annular material distribution device, it can be limited that the guiding unit 3 is only an arc-shaped block, or it can be limited that there are only multiple guiding units 3.

[0043] In addition, in this embodiment, the guiding unit 3 is detachably connected to the cartridge 2. Based on this, it is convenient to repair and replace the guiding unit 3, thus achieving the technical effect of improving the simplicity of the repair of the vertical annular material distribution device.

[0044] Among them, in combination Figure 4 As shown, a first through hole 301 is provided on the guiding unit 3, and a threaded hole corresponding to the first through hole 301 is provided on the cartridge 2. The guiding unit 3 and the cartridge 2 are threadedly connected by a bolt passing through them, realizing the detachable connection between the guiding unit 3 and the cartridge 2.

[0045] As a transformable embodiment, it can also be that threaded holes are provided on both the guiding unit 3 and the cartridge 2.

[0046] Of course, in other embodiments, according to the different designs of the vertical annular material distribution device, the detachable connection method between the guiding unit 3 and the cartridge 2 is adjusted. Or, the guiding unit 3 is fixedly connected to the cartridge 2.

[0047] In addition, in combination Figure 1 and Figure 2 As shown, in this embodiment, the vertical annular material distribution device includes: The converging unit 4 is internally provided with a converging channel. The converging unit 4 is connected to the barrel 2, and the converging channel is communicated with the cloth channel 201. Along the direction from the converging channel close to the cloth channel 201 to away from the cloth channel 201, the diameter of the converging channel gradually increases. That is, the converging unit 4 and the converging channel are in a horn shape, and the barrel 2 can be in a cylindrical structure.

[0048] Among them, the smallest diameter part of the horn shape is connected to the barrel 2, and the largest diameter part of the horn shape is used to collect materials. Based on this, the feeding area of the converging channel can be increased, and at the same time, the limitation on the feeding angle of the materials can be reduced, so as to reduce the difficulty of the materials entering the barrel 2, thereby achieving the technical effect of improving the simplicity of use of the vertical annular cloth feeding device.

[0049] Preferably, the converging unit 4 and the barrel 2 are integrally arranged. Based on this, the technical effect of improving the connection stability between the converging unit 4 and the barrel 2 can be achieved.

[0050] Of course, in other embodiments, according to the different designs of the vertical annular cloth feeding device, the shapes of the converging unit 4 and the barrel 2 are adjusted.

[0051] In other embodiments, according to the different designs of the vertical annular cloth feeding device, the connection manner between the converging unit 4 and the barrel 2 is adjusted. It can also be that the converging unit 4 and the barrel 2 are detachably connected, or the converging unit 4 and the barrel 2 are welded.

[0052] As a variable implementation manner, it can also be that the vertical annular cloth feeding device does not include the converging unit 4.

[0053] In other embodiments, according to the different designs of the vertical annular cloth feeding device, only the converging unit 4 is defined as a converging unit made of manganese steel, or only the converging unit 4 and the barrel 2 are integrally arranged.

[0054] In addition, in this embodiment, the converging unit 4 is a converging unit made of manganese steel, the barrel 2 is a barrel made of manganese steel, and the guiding unit 3 is a guiding unit made of manganese steel. Based on this, the impact resistance of the converging unit 4, the barrel 2 and the guiding unit 3 can be improved, and the damage caused by the falling of the ore to the converging unit 4, the barrel 2 and the guiding unit 3 can be avoided, thereby achieving the technical effect of improving the use reliability of the converging unit 4, the barrel 2 and the guiding unit 3.

[0055] Of course, in other embodiments, according to the different designs of the vertical annular cloth feeding device, the materials of the converging unit 4, the barrel 2 and the guiding unit 3 are adjusted.

[0056] In addition, as shown in Figure 1 and Figure 2 In this embodiment, the vertical annular cloth feeding device includes: The driving unit 5, which is connected to the barrel 2, is used to drive the rotation of the barrel 2. By providing a driving force to the barrel 2 through the driving unit 5, manual operation is not required, thereby achieving the technical effect of improving the cloth feeding efficiency of the vertical ring-shaped cloth feeding device. At the same time, the technical effect of saving manpower can also be achieved.

[0057] Among them, the driving unit 5 includes: The driving structure 501 is connected to the base 1.

[0058] The first transmission structure, which is connected to the driving structure 501, is used to rotate around its own axis direction under the drive of the driving structure 501.

[0059] The second transmission structure, which is in transmission connection with the first transmission structure, is used to rotate along with the first transmission structure.

[0060] The third transmission structure, which is connected to the second transmission structure, is used to rotate around its own axis direction along with the second transmission structure.

[0061] The fourth transmission structure 502, which is connected to the third transmission structure, is used to rotate around its own axis direction along with the third transmission structure.

[0062] The fifth transmission structure 503, which is in transmission connection with the fourth transmission structure 502 and is rotatably connected within the base 1, is connected to the barrel 2 and is used to drive the rotation of the barrel 2.

[0063] Specifically, the driving structure 501 is a motor, the first transmission structure is a first helical gear, the second transmission structure is a second helical gear, the third transmission structure is a transmission shaft, the fourth transmission structure 502 is a gear, and the fifth transmission structure 503 is a gear ring. Among them, the second transmission structure meshes with the first transmission structure, and the fifth transmission structure 503 meshes with the fourth transmission structure 502. Through the driving structure 501, the first transmission structure, the second transmission structure, the third transmission structure, the fourth transmission structure 502, and the fifth transmission structure 503, the rotation of the barrel 2 can be driven. Among them, the motor of the driving structure 501 can rotate forward and backward, and at the same time, the rotation speed of the driving structure 501 can be adjusted, so as to adjust the rotation direction and rotation speed of the barrel 2 according to the processing amount of the material by the vertical ring-shaped cloth feeding device and the actual needs.

[0064] As an alternative implementation, it can also be that the vertical ring-shaped cloth feeding device does not include the driving unit 5.

[0065] Of course, in other embodiments, according to the different designs of the vertical ring-shaped cloth feeding device, the specific structure of the driving unit 5 is adjusted.

[0066] In other embodiments, depending on the design of the vertical annular feeding device, it is only defined that the vertical annular feeding device includes a driving unit 5, or it is only defined that the guiding unit 3 is detachably connected to the barrel 2.

[0067] In addition, in this embodiment, the vertical annular feeding device includes: A positioning unit, which is arranged between the base 1 and the fifth transmission structure 503 and is used to limit the degree of freedom of the fifth transmission structure 503.

[0068] By providing the positioning unit, the degree of freedom of the fifth positioning part can be limited, so that the fifth positioning part only rotates around its own axis, thereby improving the reliability of the rotation of the fifth positioning part, and thus achieving the technical effect of improving the reliability of the use of the vertical annular feeding device.

[0069] Among them, the positioning unit includes: A first positioning structure, which is arranged on the contact surface between the fifth transmission structure 503 and the base 1.

[0070] A second positioning structure, which is arranged on the base 1, and the second positioning structure cooperates with the first positioning structure to limit the degree of freedom of the first positioning structure in its radial direction, so that the fifth transmission structure 503 only rotates along its own axis direction.

[0071] Among them, the first positioning structure can be arranged along Figure 4 the side surface as shown. The second positioning structure is arranged on the side surface of the base 1. The first positioning structure is a positioning block, and the second positioning structure is a groove, and the positioning block is arranged in the groove. Based on this, through the cooperation connection between the positioning block and the groove, the radial position of the fifth positioning part can be limited, so that the fifth positioning part only rotates around its own axis, thereby achieving the technical effect of improving the reliability of the use of the vertical annular feeding device. At the same time, the positioning block and the groove have the technical effect of simple structure, so as to achieve the technical effect of reducing the manufacturing difficulty of the positioning unit, and thus achieve the technical effect of improving the design simplicity of the vertical annular feeding device.

[0072] As an alternative embodiment, it can also be that the first positioning structure is a groove and the second positioning structure is a positioning block.

[0073] Of course, in other embodiments, depending on the design of the vertical annular feeding device, the specific structures of the first positioning structure and the second positioning structure are adjusted.

[0074] In other embodiments, depending on the design of the vertical annular feeding device, it can also be that the vertical annular feeding device does not include a positioning unit.

[0075] According to the embodiment of the present invention, in the second aspect, a vertical annular ore dressing machine is further provided, including: The vertical annular feeding device of this embodiment.

[0076] The sorting device is spaced at the bottom of the vertical annular feeding device and is used to receive the materials conveyed by the vertical annular feeding device and sort the materials according to different qualities.

[0077] Among them, the sorting device includes a vibrating disk 6, which is spaced at the bottom of the vertical annular feeding device. The vibrating disk 6 is sequentially provided with a connected buffer surface 603, a conveying surface 604, and a stabilizing surface 605 from the center to the edge. The shapes of the buffer surface 603, the conveying surface 604, and the stabilizing surface 605 are all annular, and the heights of the buffer surface 603, the conveying surface 604, and the stabilizing surface 605 gradually decrease. Among them, the buffer surface 603 is used to buffer the materials so that the speed of the materials entering the conveying surface 604 from the buffer surface 603 is zero. The conveying surface 604 has a first part 6041 close to the buffer surface 603 and a second part 6042 close to the stabilizing surface 605. There is a first angle between the first part 6041 and the horizontal plane, and a second angle between the second part 6042 and the horizontal plane. The first angle is greater than the second angle.

[0078] Among them, the vibrating disk 6 can be used to adjust the movement speed of the materials. Specifically, the materials can first fall on the buffer surface 603 and then move sequentially along the buffer surface 603, the conveying surface 604, and the stabilizing surface 605. Since the shapes of the buffer surface 603, the conveying surface 604, and the stabilizing surface 605 are all annular, a large amount of materials can fall in a circular feeding manner along the buffer surface 603, the conveying surface 604, and the stabilizing surface 605 until they leave the vibrating disk 6, thereby ensuring the feeding quantity.

[0079] During the feeding process, the buffer surface 603 can receive the materials in free fall and decelerate the materials, reducing the initial speed of the materials when entering the conveying surface 604 so that the speed of the materials is zero when moving onto the conveying surface 604. When the materials move on the conveying surface 604, the materials can move in a straight line along the surfaces of the first part 6041 and the second part 6042. Since the angle of the first part 6041 is greater than the angle of the second part 6042, the acceleration of the materials on the first part 6041 will be greater than the acceleration of the materials on the second part 6042. Therefore, the first part 6041 can be used to accelerate the materials so that the materials quickly pass through the conveying surface 604, and the second part 6042 can be used to slow down the acceleration trend of the materials to control the speed of the materials when leaving the vibrating disk 6 to meet the preset requirements. This not only reduces the time for the materials to pass through the conveying surface 604 but also can slow down the acceleration trend of the materials so that the speed of the materials when entering the stabilizing surface 605 can be controlled. Among them, in this embodiment, the preset requirement can be that the materials can do free fall when leaving the stabilizing surface 605, which is convenient for subsequent detection and impurity removal of the materials.

[0080] With such a setting, the vibrating disk 6 of this embodiment can improve the material separation quantity through the cooperation of the buffer surface 603, the conveying surface 604 and the stabilizing surface 605, and can also well control the speed of the material entering the detection link and the impurity removal link, improving the accuracy of detection and impurity removal, and thus improving the sorting effect.

[0081] Of course, in other embodiments, according to the different designs of the vibrating disk 6, the movement speed and direction of the ore raw material leaving the stabilizing surface 605 are adjusted in the preset requirements.

[0082] In this embodiment, the vibrating disk 6 can be made of manganese steel material, and the surface roughness of the vibrating disk 6 is 6.3 μm. With such a setting, while ensuring that the material can move stably along the surface of the vibrating disk 6, the movement speed of the material can also be controlled.

[0083] In this embodiment, the speed of the material leaving the stabilizing surface 605 is 0.13 m / s to 0.25 m / s.

[0084] After a large number of experimental demonstrations by the applicant, when the speed of the material leaving the stabilizing surface 605 is less than 0.13 m / s, the material separation quantity will decrease and the sorting efficiency will be reduced. When the speed of the material leaving the stabilizing surface 605 is greater than 0.25 m / s, the sorting accuracy will be reduced. The applicant found that this is because the horizontal speed of the material is too fast, causing the material to move in a parabolic motion when leaving the vibrating disk 6, which will cause some materials to deviate from the effective action areas of the downstream detection device and the impurity removal device. Therefore, the speed range of the material leaving the stabilizing surface 605 is determined to be 0.13 m / s to 0.25 m / s. This can ensure that the movement trajectory of the material when leaving the vibrating disk 6 is close to a free-fall motion in the vertical direction, slowing down the tendency of the material to move in a parabolic motion, so as to facilitate the material to directly fall within the effective detection area of the downstream detection device and the effective action area of the impurity removal device.

[0085] Combined Figure 5 、 Figure 6 and Figure 7 As shown in, in this embodiment, the center of the vibrating disk 6 has a platform surface 602 for installing the vibrator 10. The vibrator 10 can drive the vibrating disk 6 to vibrate, so that the ore raw material moves radially on the surface of the vibrating disk 6 to avoid material accumulation on the vibrating disk 6 and cause jams. At the same time, the vibrator 10 can also improve the movement speed of the material to a certain extent. For example, the platform surface 602 is provided with a second through hole 601, and the vibrator 10 is installed in the second through hole 601. The vibration frequency of the vibrator 10 driving the vibrating disk 6 is 50 HZ.

[0086] After a large number of experiments and demonstrations by the applicant, the faster the vibration frequency of the vibrating disk 6, the faster the movement speed of the material on the vibrating disk 6 and the shorter the time for the material to pass through the vibrating disk 6. However, when the vibration frequency is greater than 50HZ, the motor of the vibrator 10 has a risk of overheating and damage. Therefore, setting the vibration frequency of the vibrating disk 6 at 50HZ greatly shortens the time for the material to pass through the vibrating disk 6 and can also ensure the safety of the motor of the vibrator during use.

[0087] Combined with Figure 14 As shown, in this embodiment, the buffer surface 603 and the conveying surface 604 cooperate with the external first baffle device 7. A second baffle device 8 is provided between the first part 6041 and the second part 6042. When the vibrator 10 is working, the distance between the first baffle device 7 and the vibrating disk 6 changes regularly, forming a first gap with a periodically changing size. The distance between the second baffle device 8 and the vibrating disk 6 continuously changes regularly, forming a second gap with a periodically changing size. When the size of the first gap is smaller than the size of the material, the material is blocked by the first baffle device 7 to slow down the speed of the material, so that the speed of the material when entering the first part 6041 of the conveying surface 604 is zero. When the size of the first gap is larger than the size of the material, the material passes through the first gap and enters the first part 6041. When the size of the second gap is smaller than the size of the material, the material is blocked by the second baffle device 8 to slow down the speed of the material. When the second gap is larger than the size of the material, the material passes through the second gap and enters the second part 6042. This is because the material makes a free-fall motion before entering the buffer surface 603 and its speed is relatively fast. The first baffle device 7 can slow down the speed of the material and initially control the speed of the material. The first part 6041 allows the material to accelerate to quickly pass through the conveying surface 604. The second baffle device 8 can slow down the speed of the material when entering the second part 6042, so as to facilitate the second part 6042 to control the speed of the material. And with the cooperation of the vibrator 10, it is ensured that the speed of the subsequent material leaving the stable surface 605 is 0.13m / s to 0.25m / s.

[0088] In an implementation manner of this embodiment, the first baffle device 7 and the second baffle device 8 can be curtain baffles. The cross-sectional shape of the curtain baffle can be annular. The radial dimensions of the two curtain baffles are different to respectively cooperate with the corresponding positions of the vibrating disk 6. A gap for allowing the material to pass through is formed between the open end of the curtain baffle and the vibrating disk 6.

[0089] Combined with Figure 5 、 Figure 6 and Figure 7As shown, in this embodiment, the angle range between the first part 6041 and the horizontal plane is from 20 degrees to 55 degrees, and the angle between the second part 6042 and the horizontal plane is from 15 degrees to 25 degrees. Through experiments, the applicant demonstrated that when the angle of the first part 6041 is less than 20 degrees, the movement speed of the material will be too slow, reducing the speed of the material passing through the vibrating disk 6. When the angle of the first part 6041 is greater than 55 degrees, the movement speed of the material will be too fast, and it is not easy to control the final speed of the material leaving the vibrating disk 6 through the second part 6042. The second part 6042 is set at 15 degrees to 25 degrees. For example, it can be 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees, 20 degrees, 21 degrees, 22 degrees, 23 degrees, 24 degrees or 25 degrees, and can also include non-integer angles among them. When the angle of the second part 6042 is larger, the passing time of the material is shorter and the speed is faster, but it can still meet the requirement of not exceeding the maximum speed of 0.25 m / s. With such a setting, the second part 6042 can cooperate with the surface roughness and vibration frequency of the vibrating disk 6 to control the material to move at a uniform speed or a slow acceleration, and can control the speed of the material when leaving the edge of the vibrating disk 6 within the range of 0.13 m / s to 0.25 m / s.

[0090] In order to increase the material separation amount, it is necessary to increase the distance for the material to move on the vibrating disk 6. On this basis, the outer diameter size of the vibrating disk 6 can be adjusted according to the actual structure to ensure that the distance and angle of the first part 6041 and the second part 6042 are coordinated to meet the requirements of the blanking speed. However, considering that the movement speed of the material on the surface of the vibrating disk 6 is not only related to the angles of the first part 6041 and the second part 6042, but also related to the distances that the material moves on the first part 6041 and the second part 6042. Therefore, through a large number of experimental demonstrations, the applicant obtained the following two groups of experimental data under the condition that the speed of the material leaving the vibrating disk 6 is 0.13 m / s to 0.25 m / s. The vibration frequency of the vibrating disk 6 in both groups of experimental data is 50 HZ.

[0091] Combined with Figure 5 、 Figure 6 and Figure 7As shown, in an implementation manner of this embodiment, the distance range for the material to move in the first part 6041 and the second part 6042 is 300 mm to 320 mm. Among them, the distance of the first part 6041 is 147 mm to 169 mm, the distance of the second part 6042 is 151 mm to 153 mm, the angle between the first part 6041 and the horizontal plane is 20 degrees to 40 degrees, and the angle between the second part 6042 and the horizontal plane is 15 degrees to 25 degrees. Through a large number of experimental demonstrations by the applicant, when the total distance of the first part 6041 and the second part 6042 is 300 mm to 320 mm, it can not only ensure that the material quickly passes through the vibrating disk 6, but also can well control the speed of the material when it leaves the vibrating disk 6.

[0092] Furthermore, the applicant found that there is no proportional relationship between the distances of the first part 6041 and the second part 6042. With the cooperation of the second baffle device 8, the second part 6042 has a greater impact on the final speed. Therefore, through a large number of experimental demonstrations by the applicant, when the distance range for the ore raw material to move in the first part 6041 and the second part 6042 is 300 mm to 320 mm, when the angle of the second part 6042 is set to 15 degrees to 25 degrees and the distance of the second part 6042 is set to 151 mm to 153 mm, the control of the final speed can be satisfied. To control the moving speed of the material on the first part 6041, the angle of the first part 6041 needs to be adjusted. When the angle of the first part 6041 is less than 20 degrees, the speed will be slower, which is not conducive to the material quickly passing through the vibrating disk 6. When the angle of the first part 6041 is greater than 40 degrees, the speed of the material will be too fast, which is not conducive to the first part 6041 controlling the speed of the material. Therefore, the angle range of the first part 6041 is 20 degrees to 40 degrees, and the distance of the first part 6041 can be 147 mm to 169 mm. For example, when the distance of the second part 6042 is 151 mm, the distance of the first part 6041 can be 149 mm to 169 mm, or when the distance of the second part 6042 is 152 mm, the distance of the first part 6041 is 148 mm to 168 mm, or when the distance of the second part 6042 is 153 mm, the distance of the first part 6041 is 147 mm to 167 mm. Of course, other combinations are also included and will not be listed one by one here. With such settings, when the first part 6041 cooperates with vibration, the material can do an accelerating motion, so as to quickly pass through the first part 6041. When the second part 6042 cooperates with vibration, the material does a uniform linear motion or a slow accelerating motion, so that the speed of the material leaving the stable surface 605 is within the range of 0.13 m / s to 0.25 m / s.

[0093] Preferably, the distance range for the material to move in the first part 6041 and the second part 6042 is 300 mm to 320 mm. Among them, the distance of the first part 6041 is 147 mm to 169 mm, the distance of the second part 6042 is 151 mm to 153 mm, the angle between the first part 6041 and the horizontal plane is 30 degrees, and the angle between the second part 6042 and the horizontal plane is 15 degrees to 25 degrees. This can not only ensure that the material quickly passes through the vibrating bowl 6, but also can well control the speed of the material when it leaves the vibrating bowl 6.

[0094] In this embodiment, the outer diameter range of the vibrating bowl 6 is selected to be 1200 mm to 1600 mm. The outer diameter of the experimental vibrating bowl 6 is 1460 mm. The outer diameter of the vibrating bowl 6 can be selected according to the actual structure of the ore dressing machine, that is, it can be increased or decreased on the basis of the above range, as long as the distance and angle matching relationship between the first part 6041 and the second part 6042 are ensured.

[0095] Combined Figure 8 、 Figure 9 and Figure 10 As shown, in another embodiment of this embodiment, the distance range for the material to move in the first part 6041 and the second part 6042 is 430 mm to 450 mm. Among them, the distance of the first part 6041 is 176 mm to 198 mm, the distance of the second part 6042 is 252 mm to 254 mm, the angle between the first part 6041 and the horizontal plane is 35 degrees to 55 degrees, and the angle between the second part 6042 and the horizontal plane is 15 degrees to 25 degrees. Through a large number of experimental demonstrations by the applicant, when the outer diameter size of the vibrating bowl 6 is 1680 mm and the total distance between the first part 6041 and the second part 6042 is 430 mm to 450 mm, it can not only ensure that the material quickly passes through the vibrating bowl 6, but also can well control the speed of the material when it leaves the vibrating bowl 6.

[0096] Furthermore, the applicant found through data comparison that when the moving distances of the materials on the vibrating bowl 6 are different, there is no proportional relationship between the first parts 6041 of the two, nor is there a proportional relationship between the second parts 6042 of the two. When the moving distances of the ore raw materials in the first part 6041 and the second part 6042 range from 430 mm to 450 mm, with the cooperation of the second baffle device 8, the second part 6042 has a greater influence on the final speed. Therefore, after a large number of experimental demonstrations, when the angle of the second part 6042 is set to 15 degrees to 25 degrees and the distance of the second part 6042 is set to 252 mm to 254 mm, the control of the final speed can be satisfied. To control the moving speed of the materials on the first part 6041, the angle of the first part 6041 needs to be adjusted. When the angle of the first part 6041 is less than 35 degrees, the speed will be slow, which is not conducive to the materials quickly passing through the vibrating bowl 6. When the angle of the first part 6041 is greater than 55 degrees, the speed of the materials will be too fast, which is not conducive to the first part 6041 controlling the speed of the materials. Therefore, the angle range of the first part 6041 is 35 degrees to 55 degrees, and the distance of the first part 6041 can be 176 mm to 198 mm. For example, when the distance of the second part 6042 is 252 mm, the distance of the first part 6041 can be 178 mm to 198 mm; or when the distance of the second part 6042 is 253 mm, the distance of the first part 6041 is 177 mm to 197 mm; or when the distance of the second part 6042 is 254 mm, the distance of the first part 6041 is 176 mm to 196 mm. Of course, other combinations are also included, which will not be listed one by one here. With such settings, when the first part 6041 cooperates with the vibration, the materials can move in an accelerated motion, so as to quickly pass through the first part 6041. When the second part 6042 cooperates with the vibration, the materials move in a uniform linear motion or a slow accelerated motion, so that the speed of the materials leaving the stable surface 605 is within the range of 0.13 m / s to 0.25 m / s.

[0097] Preferably, the moving distances of the materials in the first part 6041 and the second part 6042 range from 430 mm to 450 mm, wherein the distance of the first part 6041 is 176 mm to 198 mm, the distance of the second part 6042 is 252 mm to 254 mm, the angle between the first part 6041 and the horizontal plane is 47 degrees, and the angle between the second part 6042 and the horizontal plane is 15 degrees to 25 degrees, which can not only ensure that the materials quickly pass through the vibrating bowl 6, but also can well control the speed of the materials when leaving the vibrating bowl 6.

[0098] In this embodiment, the outer diameter of the vibrating disk 6 is selected in the range of 1500 mm to 2000 mm. The outer diameter of the experimental vibrating disk 6 is 1680 mm. The outer diameter of the vibrating disk 6 can be selected according to the actual structure of the ore dressing machine, that is, it can be increased or decreased on the basis of the above range, as long as the distance and angular matching relationship between the first part 6041 and the second part 6042 are ensured.

[0099] Combined with Figure 5 、 Figure 6 and Figure 7 As shown, in this embodiment, the buffer surface 603 is an inclined surface. For example, the angle between the buffer surface 603 and the horizontal plane can be 15 degrees, or the angle of the buffer surface 603 can be adjusted to other angles according to the actual structure requirements. The stable surface 605 is parallel to the horizontal plane. The stable surface 605 can guide the movement trajectory of the material. The material moves along the angle of the second part 6042 before entering the stable surface 605. In order to prevent the material from making a projectile motion, the stable surface 605 can first guide the material to move in the horizontal direction. Matching the movement speed range of the material from 0.13 m / s to 0.25 m / s, the material can fall within the action range of the detection device and the impurity removal device when it leaves the stable surface 605.

[0100] Combined with Figure 11 As shown, in this embodiment, an arc-shaped guiding surface 6051 is provided at one end of the stable surface 605 facing away from the conveying surface 604. The arc-shaped guiding surface 6051 is used to guide the material to move in the height direction. After the material leaves the stable surface 605, it can move along the arc-shaped guiding surface 6051, so as to make a free-fall motion in the height direction, which is convenient for entering the action range of the downstream detection device and impurity removal device.

[0101] Combined with Figure 7 and Figure 12 As shown, the shape of the vibrating disk 6 is funnel-shaped. The buffer surface 603, the conveying surface 604 and the stable surface 605 are arranged on the convex surface of the vibrating disk 6. A plurality of strip-shaped reinforcing ribs 608 are uniformly arranged on the concave surface of the vibrating disk 6. The strip-shaped reinforcing ribs 608 extend from the center of the vibrating disk 6 to the edge. For example, ten strip-shaped reinforcing ribs 608 can be arranged on the concave surface of the vibrating disk 6, so as to improve the structural strength of the vibrating disk 6 and improve the impact resistance of the vibrating disk 6. A ring-shaped reinforcing rib 609 can be arranged at the edge of the concave surface of the vibrating disk 6. For example, two ring-shaped reinforcing ribs 609 are arranged on the concave surface of the vibrating disk 6, respectively located at a position close to the center and a position close to the edge, so as to further improve the structural strength of the vibrating disk 6.

[0102] Combined with Figure 12As shown, a plurality of mounting positions 6010 are provided on the concave surface edge of the vibration plate 6, and the mounting positions 6010 can be used to be connected to the bracket 11 of the ore dressing machine, for example, connected to the bracket 11 through a rubber spring.

[0103] Combination Figure 6 As shown, in one implementation of the present embodiment, a first step surface 606 is provided between the buffer surface 603 and the conveying surface 604. Since the vibration plate 6 needs to be equipped with the exciter 10 and cooperate with the material distribution device, the height dimension of the vibration plate 6 has requirements. The first step surface 606 can connect the buffer surface 603 and the conveying surface 604. For example, when the distance range for the movement of the ore raw material by the first part 6041 and the second part 6042 on the vibration plate 6 is 300 mm to 320 mm, since the angle of the first part 6041 is 20 degrees to 40 degrees, the first step surface 606 has a good transition connection effect.

[0104] Combination Figure 9 As shown, when the distance range for the movement of the ore raw material between the first part 6041 and the second part 6042 on the vibration plate 6 is 430 mm to 450 mm, the angle of the first part 6041 is 35 degrees to 55 degrees, and the first step surface 606 does not need to be set on the vibration plate 6. The first part 6041 can be connected to the buffer surface 603 by relying on the angle and distance.

[0105] Combination Figure 6 As shown, in one implementation of this embodiment, a second step surface 607 is provided on the edge of the stabilizing surface 605 away from the conveying surface 604. Since the vibration plate 6 has a certain thickness, the second step surface 607 can prevent the material from making secondary contact with the vibration plate 6 when leaving the arc guide surface 6051.

[0106] Combination Figure 13 , Figure 14 and Figure 15 As shown, the sorting device includes a frame 9 and an exciter 10.

[0107] The vibration disk 6 is installed on the frame 9 through the bracket 11, and the exciter 10 is set at the center of the vibration disk 6 to provide an exciting force to the vibration disk 6. The frame 9 is connected to the base 1. The exciter 10 is installed on the frame 9 through the bracket 11, and the vibration disk 6 is opposite to the barrel 2 to receive the material from the barrel 2. For example, after the material passes through the barrel 2, it will fall on the vibration disk 6, and the exciting force of the exciter 10 drives the vibration disk 6 to vibrate, so that the material falls evenly along the annular surface of the vibration disk 6, so that the detection device and impurity removal device below can detect and remove impurities.

[0108] Combination Figure 15As shown, the lower surface of the vibration disk 6 is connected to the bracket 11 through a plurality of elastic support columns 12. Then, when the exciter 10 is working, the vibration disk 6 can vibrate relative to the bracket 11 through the elastic support columns 12 to avoid the exciting force being transmitted to the bracket 11. The elastic support columns 12 can be made of rubber or silicone material. The elastic support columns 12 have a hollow inner cavity. The first fastener 13 and the second fastener 14 are respectively provided at both ends of the hollow inner cavity. The first fastener 13 is connected to the vibration disk 6, and the second fastener 14 is connected to the bracket 11 to ensure that the vibration disk 6 can vibrate relative to the bracket 11. The first fastener 13 and the second fastener 14 have the same structure, both of which include an insert that can be embedded in the hollow inner cavity, and a screw provided on the insert, and the screw is used to tighten on the corresponding threaded hole on the vibration disk 6 or the bracket 11.

[0109] The elastic support column 12 may also be replaced by a rubber spring.

[0110] The bracket 11 can be installed on the frame 9 through a support frame, which has multiple support arms connected to the edge of the bracket 11, thereby ensuring that there is a certain gap between the edge of the vibration plate 6 and the support frame, and the material can fall from the gap to facilitate subsequent detection and impurity removal.

[0111] A second through hole 601 is provided at the center of the vibration disk 6. The vibration disk 6 can be used as a receiving structure and a conveying structure for materials. The vibration disk 6 can be made of manganese steel material. The vibration of the vibration disk 6 can be controlled by the exciter 10, so that the materials move radially on the surface of the vibration disk 6.

[0112] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
