Abstract

This invention relates to the field of ore sorting technology, and discloses a vertical annular feeding device and a mineral processing machine. The vertical annular feeding device includes a base, a feed cylinder, and a guiding unit. By setting up the guiding unit and the feed cylinder rotatably connected to the base, a portion of the material entering the feed cylinder through the inlet is transported along the guiding unit. With the rotation of the feed cylinder, the material on the guiding unit diffuses towards the edge of the feed cylinder under centrifugal force. The other portion of the material is transported through a feeding channel without the guiding unit, i.e., this portion is transported through the center of the feed cylinder. Based on this, material can be distributed both through the center and the edges of the feed cylinder, achieving distribution without dead zones, thereby improving the uniformity of material distribution.

Description

Technical Field

[0001] This invention relates to the field of ore sorting technology, specifically to a vertical annular feeding device and a mineral processing machine. Background Technology

[0002] Existing ore screening methods first involve feeding the ore into a sorting device using a vertical annular feeding device, then using a laser within the sorting device to separate and store superior and inferior ores. Specifically, the vertical annular feeding device includes:

[0003] The housing is located above the sorting device. The housing has a feed inlet at the top and a discharge outlet connected to the sorting device at the bottom.

[0004] In actual use, it was found that after the ore enters the sorting device through the feed inlet and discharge outlet, it directly accumulates in the center 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 edges. This uneven distribution of material causes the characteristics of inferior ore to not be recognized by the sorting device and enter the storage area of ​​superior ore, resulting in a decrease in the yield of superior ore. Summary of the Invention

[0005] In view of this, the present invention provides a vertical annular feeding device and a mineral processing machine to solve the problem that uneven feeding in existing vertical annular feeding devices leads to inferior ore characteristics not being recognized by the sorting device and entering the storage area of ​​superior ore, resulting in a reduction in the yield of superior ore.

[0006] In a first aspect, the present invention provides a vertical annular fabric making device, comprising:

[0007] base;

[0008] The material cylinder has a vertical structure and is rotatably connected to the base. The material cylinder has a material distribution channel inside, so that the material cylinder has a ring structure. One end of the material distribution channel is the inlet and the other end is the outlet. The material cylinder is used to transport materials.

[0009] A guiding unit is disposed on the inner wall of the fabric channel and is used to guide the transmission direction of the material.

[0010] Beneficial effects: By setting up a guiding unit and a rotating material cylinder connected to the base, some of the material entering the cylinder through the inlet is transported along the guiding unit. Combined with the rotation of the cylinder, the material on the guiding unit is diffused towards the edge of the cylinder under centrifugal force. The other part of the material is transported through the distribution channel without the guiding unit, meaning this part is transported through the center of the cylinder. Based on this, material can be distributed both through the center and the edges of the cylinder, achieving distribution without dead angles and thus improving the uniformity of material distribution.

[0011] Furthermore, by rotating the material cylinder to the base, the material passing through the outlet is always subjected to external force, thus preventing material blockage and improving the material distribution efficiency of the vertical annular material distribution device. Simultaneously, the small size of this vertical annular material distribution device reduces processing costs.

[0012] In one optional implementation, the guiding unit is an arc-shaped block, with one end of the guiding unit close to the inlet and the other end close to the outlet;

[0013] And / or, the guiding unit is provided in multiple forms.

[0014] Beneficial effects: With the cooperation of the rotating material cylinder, the material placed on the guide unit can rotate and have centrifugal force, so that the material can be transferred along the edge of the material cylinder and has a tendency to spread outward, thereby increasing the amount of material transferred at the edge of the material cylinder and avoiding the material being placed only at the center of the fabric, thus achieving the technical effect of improving the uniformity of the vertical ring fabric distribution device.

[0015] By limiting the number of guiding units, the number of connection points between the guiding units and the material can be increased, ensuring that the material falling onto the guiding units is always subjected to centrifugal force, thereby achieving the technical effect of improving the reliability of material distribution along the edge of the material cylinder.

[0016] In one optional embodiment, adjacent guide units are spaced apart along a direction parallel to the axis of the material cylinder, and are used to cut the material cylinder along a direction parallel to the axis of the material cylinder. The cutting position is located between the guide unit closest to the inlet and the guide unit closest to the outlet. The cut material cylinder is unfolded to form a plane, and the height of the plurality of guide units in the plane gradually decreases, and the tilt direction of the plurality of guide units in the plane is the same.

[0017] Beneficial effects: By limiting the position between adjacent guide units along the axis parallel to the barrel, the reliability of the material rotating with the barrel can be improved, thus avoiding the situation in related technologies where the material is only at the center of the shell, thereby achieving the technical effect of improving the uniformity of material distribution.

[0018] In one optional embodiment, the vertical annular fabric distribution device includes:

[0019] The gathering unit has a gathering channel inside. The gathering unit is connected to the material cylinder. The gathering channel is connected to the fabric channel. The diameter of the gathering channel gradually increases along the direction from the direction of approaching the fabric channel to the direction of moving away from the fabric channel.

[0020] Beneficial effects: By limiting the direction along the gathering channel from near to far from the material distribution channel, the diameter of the gathering channel gradually increases, making the gathering unit funnel-shaped. Based on this, the feeding area of ​​the gathering channel can be increased, reducing the difficulty of material entering the material cylinder, thereby improving the ease of use of the vertical annular material distribution device.

[0021] In one optional embodiment, the gathering unit is a gathering unit made of manganese steel;

[0022] And / or, the gathering unit is integrated with the material cylinder.

[0023] Beneficial effects: By limiting the gathering unit to a material made of manganese steel, the impact resistance of the gathering unit can be improved, preventing damage to the gathering unit caused by falling ore, thereby improving the technical effect of improving the reliability of the gathering unit.

[0024] By integrating the gathering unit and the material cylinder, the technical effect of improving the connection stability between the gathering unit and the material cylinder can be achieved.

[0025] In one optional embodiment, the vertical annular fabric distribution device includes:

[0026] A drive unit, connected to the material cylinder, is used to drive the rotation of the material cylinder;

[0027] And / or, the guide unit is detachably connected to the barrel.

[0028] Beneficial effects: By providing driving force to the material cylinder through the drive unit, no manual operation is required, thereby improving the material distribution efficiency of the vertical ring material distribution device and saving manpower.

[0029] The guide unit is detachably connected to the feed cylinder. This facilitates the maintenance and replacement of the guide unit, thereby improving the ease of maintenance for the vertical annular feeding device.

[0030] In one optional implementation, the drive unit includes:

[0031] A drive structure is connected to the base;

[0032] A first transmission structure is connected to the drive structure and is used to rotate about its own axis under the drive of the drive structure.

[0033] The second transmission structure is connected to the first transmission structure and is used to rotate with the first transmission structure;

[0034] The third transmission structure is connected to the second transmission structure and is used to rotate with the second transmission structure around its own axis.

[0035] The fourth transmission structure is connected to the third transmission structure and is used to rotate around its own axis along with the third transmission structure.

[0036] The fifth transmission structure is connected to the fourth transmission structure and rotatably connected to the base. The fifth transmission structure is connected to the material cylinder and is used to drive the rotation of the material cylinder.

[0037] In one optional embodiment, the vertical annular fabric distribution device includes:

[0038] A positioning unit is disposed between the base and the fifth transmission structure to restrict the degree of freedom of the fifth transmission structure along its radial direction.

[0039] Beneficial effects: By setting a positioning unit, the degree of freedom of the fifth positioning part can be limited, so that the fifth positioning part can only rotate 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 vertical ring cloth feeding device.

[0040] In one optional implementation, the positioning unit includes:

[0041] The first positioning structure is disposed in the fifth transmission structure on the contact surface between it and the base;

[0042] A second positioning structure is disposed on the base. The second positioning structure cooperates with the first positioning structure to restrict the first positioning structure's degree of freedom along its radial direction.

[0043] Secondly, the present invention also provides a vertical annular mineral processing machine, comprising:

[0044] The vertical circular fabric distribution device described above;

[0045] The sorting device is spaced at the bottom of the vertical circular fabric distribution device to receive the materials transported by the vertical circular fabric distribution device and to sort the materials according to their quality.

[0046] Beneficial effects: Since the vertical annular ore separator includes a vertical annular feeding device, it has the same effect as the vertical annular feeding device, so it will not be elaborated here. Attached Figure Description

[0075] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0076] The following combination Figures 1 to 15 The following describes embodiments of the present invention.

[0077] According to an embodiment of the present invention, in a first aspect, a vertical annular fabric making device is provided, comprising:

[0078] Base 1.

[0079] The material cylinder 2 is a vertical structure and is rotatably connected to the base 1. The material cylinder 2 is provided with a material distribution channel 201 so that the material cylinder 2 is a ring structure. One end of the material distribution channel 201 is the inlet 2011 and the other end of the material distribution channel 201 is the outlet 2012. The material cylinder 2 is used to transport materials.

[0080] The guiding unit 3 is located on the inner wall of the fabric channel 201 and is used to guide the direction of material transmission.

[0081] In the vertical annular fabric distribution device of this embodiment, by setting a guide unit 3 and a material cylinder 2 rotatably connected to the base 1, a portion of the material entering the material cylinder 2 through the inlet 2011 is transported along the guide unit 3. Combined with the rotation of the material cylinder 2, the material on the guide unit 3 diffuses towards the edge of the material cylinder 2 under the action of centrifugal force. The other portion of the material is transported through the fabric distribution channel 201, which does not have a guide unit 3; that is, this portion of the material is transported through the center of the material cylinder 2. Based on this, the material can be distributed both through the center and the edge of the material cylinder 2, achieving distribution without dead angles and thus improving the uniformity of the fabric distribution.

[0082] Furthermore, by rotatably connecting the material cylinder 2 to the base 1, the material passing through the discharge port 2012 is always subjected to external force to avoid material blockage, thereby 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 size, which can achieve the technical effect of saving processing costs.

[0083] In this embodiment, the material is a mixture of superior and inferior ores. Of course, in other embodiments, the type of material may be adjusted depending on the application scenario of the vertical annular feeding device.

[0084] In addition, combined Figure 1 As shown, in this embodiment, the material cylinder 2 is made into a ring structure by means of the material channel 201, and the top end of the material channel 201 is the inlet 2011 and the bottom end of the material channel 201 is the outlet 2012, so that the material cylinder 2 is a vertical structure.

[0085] Of course, in other embodiments, the structure of the material cylinder 2 and the positions of the inlet 2011 and outlet 2012 are adjusted according to the different designs of the vertical annular material feeding device.

[0086] In addition, combined Figure 2 As shown, in this embodiment, the guide unit 3 is an arc-shaped block. One end of the guide unit 3 is close to the inlet 2011, and the other end of the guide unit 3 is close to the outlet 2012. That is, the arc-shaped block is along... Figure 4 The vertical heights are different. Based on this, with the rotation of the material cylinder 2, the material placed on the guide unit 3 can rotate and have centrifugal force, so that this part of the material can be transferred along the edge of the material cylinder 2 and has a tendency to spread outward, thereby increasing the amount of material transferred at the edge of the material cylinder 2, avoiding the material being placed only at the center of the fabric, and thus achieving the technical effect of improving the uniformity of the vertical annular fabric distribution device.

[0087] Among them, combined Figure 2 As shown, multiple guiding units 3 are provided. Based on this, the number of connection points between the guiding units 3 and the material can be increased, ensuring that the material falling onto the guiding units 3 is always subjected to centrifugal force, thereby achieving the technical effect of improving the reliability of material distribution along the edge of the material cylinder 2. In this embodiment, the number of guiding units 3 is not excessively limited.

[0088] Specifically, adjacent guide units 3 are spaced apart along the axis parallel to the material cylinder 2, and are used to cut the material cylinder 2 along the axis parallel to the material cylinder 2. The cutting position is located between the guide unit 3 closest to the inlet 2011 and the guide unit 3 closest to the outlet 2012. The cut material cylinder 2 is unfolded to form a plane. The height of the multiple guide units 3 in the plane gradually decreases, and the tilt direction of the multiple guide units 3 in the plane is the same.

[0089] For example, along the cutting position, the material cylinder 2 is unfolded. From the inlet 2011 to the outlet 2012, the guide units 3 are a first guide unit, a second guide unit, and a third guide unit. The first guide unit and the second guide unit, as well as the second guide unit and the third guide unit, have overlapping positions in the direction parallel to the axis of the material cylinder 2. This allows the material to pass through the first guide unit, enter the second guide unit, and then exit through the third guide unit from the outlet 2012. This improves the reliability of the material as the material cylinder 2 rotates, thus avoiding the situation in related technologies where the material is only at the center of the shell, thereby achieving the technical effect of improving the uniformity of material distribution.

[0090] As an alternative implementation, the guiding unit 3 can also be an arc-shaped piece. As long as the shape can guide the material conveying direction, it is within the protection scope of this invention.

[0091] Of course, in other embodiments, the shape of the guide unit 3 and the position of the multiple guide units 3 may be adjusted depending on the design of the vertical annular fabric device.

[0092] In other embodiments, depending on the design of the vertical annular fabric device, the guide unit 3 may be limited to an arc-shaped block, or the guide unit 3 may be limited to having multiple units.

[0093] Furthermore, in this embodiment, the guide unit 3 is detachably connected to the material cylinder 2. This facilitates the maintenance and replacement of the guide unit 3, thereby improving the ease of maintenance of the vertical annular fabric distribution device.

[0094] Among them, combined Figure 4 As shown, the guide unit 3 is provided with a first through hole 301, and the material cylinder 2 is provided with a threaded hole corresponding to the first through hole 301. The guide unit 3 and the material cylinder 2 are connected by bolts passing through the threaded connection to achieve a detachable connection between the guide unit 3 and the material cylinder 2.

[0095] Alternatively, both the guide unit 3 and the barrel 2 may be provided with threaded holes.

[0096] Of course, in other embodiments, the detachable connection between the guide unit 3 and the material cylinder 2 may be adjusted depending on the design of the vertical annular fabric feeding device. Alternatively, the guide unit 3 may be fixedly connected to the material cylinder 2.

[0097] In addition, combined Figure 1 and Figure 2 As shown, in this embodiment, the vertical annular fabric distribution device includes:

[0098] The gathering unit 4 has a gathering channel inside. The gathering unit 4 is connected to the material cylinder 2, and the gathering channel is connected to the fabric channel 201. The diameter of the gathering channel gradually increases along the direction from the direction of approaching the fabric channel 201 to the direction of moving away from the fabric channel 201. That is, the gathering unit 4 and the gathering channel are funnel-shaped, and the material cylinder 2 can be a cylindrical structure.

[0099] The smallest diameter part of the horn-shaped device is connected to the material cylinder 2, while the largest diameter part is used to collect materials. This increases the feeding area of ​​the gathering channel and reduces restrictions on the material feeding angle, thus lowering the difficulty for materials to enter the material cylinder 2 and improving the ease of use of the vertical annular material distribution device.

[0100] Preferably, the gathering unit 4 and the material cylinder 2 are integrated. Based on this, the technical effect of improving the connection stability between the gathering unit 4 and the material cylinder 2 can be achieved.

[0101] Of course, in other embodiments, the shapes of the gathering unit 4 and the material cylinder 2 are adjusted according to the different designs of the vertical annular fabric distribution device.

[0102] In other embodiments, depending on the design of the vertical annular fabric distribution device, the connection method between the gathering unit 4 and the material cylinder 2 can be adjusted. Alternatively, the gathering unit 4 and the material cylinder 2 can be detachably connected, or the gathering unit 4 and the material cylinder 2 can be welded together.

[0103] Alternatively, the vertical annular fabric device may not include the gathering unit 4.

[0104] In other embodiments, depending on the design of the vertical annular fabric feeding device, the gathering unit 4 is limited to being a gathering unit made of manganese steel, or the gathering unit 4 is limited to being integrated with the material cylinder 2.

[0105] In addition, in this embodiment, the gathering unit 4 is made of manganese steel, the material cylinder 2 is made of manganese steel, and the guiding unit 3 is made of manganese steel. Based on this, the impact resistance of the gathering unit 4, the material cylinder 2, and the guiding unit 3 can be improved, preventing damage to these components from falling ore, thereby enhancing their reliability.

[0106] Of course, in other embodiments, the materials of the gathering unit 4, the material cylinder 2, and the guiding unit 3 may be adjusted depending on the design of the vertical annular fabric distribution device.

[0107] In addition, combined Figure 1 and Figure 2 As shown, in this embodiment, the vertical annular fabric distribution device includes:

[0108] The drive unit 5, connected to the material cylinder 2, is used to drive the rotation of the material cylinder 2. By providing driving force to the material cylinder 2 through the drive unit 5, no manual operation is required, thereby improving the material distribution efficiency of the vertical annular material distribution device and saving manpower.

[0109] The drive unit 5 includes:

[0110] The drive structure 501 is connected to the base 1.

[0111] The first transmission structure is connected to the drive structure 501 and is used to rotate around its own axis under the drive of the drive structure 501.

[0112] The second transmission structure is connected to the first transmission structure and is used to rotate along with the first transmission structure.

[0113] The third transmission structure is connected to the second transmission structure and is used to rotate around its own axis along with the second transmission structure.

[0114] The fourth transmission structure 502 is connected to the third transmission structure and is used to rotate around its own axis along with the third transmission structure.

[0115] The fifth transmission structure 503 is connected to the fourth transmission structure 502 and is rotatably connected to the base 1. The fifth transmission structure 503 is connected to the material cylinder 2 and is used to drive the rotation of the material cylinder 2.

[0116] Specifically, the drive 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 drive shaft, the fourth transmission structure 502 is a gear, and the fifth transmission structure 503 is a gear ring. The second transmission structure meshes with the first transmission structure, and the fifth transmission structure 503 meshes with the fourth transmission structure 502. The drive 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 can drive the rotation of the material cylinder 2. The motor in the drive structure 501 can rotate in both forward and reverse directions, and its rotation speed can be adjusted to allow for adjustments to the rotation direction and speed of the material cylinder 2 based on the material processing capacity of the vertical annular feeding device and actual needs.

[0117] Alternatively, the vertical circular fabric-making device may not include the drive unit 5.

[0118] Of course, in other embodiments, the specific structure of the drive unit 5 may be adjusted according to the different designs of the vertical annular fabric device.

[0119] In other embodiments, depending on the design of the vertical annular fabric device, the vertical annular fabric device is limited to include a drive unit 5, or the guide unit 3 is limited to be detachably connected to the material cylinder 2.

[0120] In addition, in this embodiment, the vertical annular fabric distribution device includes:

[0121] The positioning unit is located between the base 1 and the fifth transmission structure 503, and is used to restrict the degree of freedom of the fifth transmission structure 503.

[0122] By setting a positioning unit, the degree of freedom of the fifth positioning part can be limited, so that the fifth positioning part can only rotate 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 vertical ring cloth feeding device.

[0123] The positioning unit includes:

[0124] The first positioning structure is located in the fifth transmission structure 503 on the contact surface between it and the base 1.

[0125] The second positioning structure is provided on the base 1 and cooperates with the first positioning structure to restrict the degree of freedom of the first positioning structure in its radial direction so that the fifth transmission structure 503 can only rotate in its own axis direction.

[0126] Among them, it can be along Figure 4 The side shown is provided with a first positioning structure, and a second positioning structure is provided on the side of the base 1. The first positioning structure is a positioning block, and the second positioning structure is a groove, with the positioning block disposed within the groove. Based on this, through the mating connection between the positioning block and the groove, the radial position of the fifth positioning part can be limited, allowing the fifth positioning part to rotate only around its own axis, thereby achieving the technical effect of improving the reliability of the vertical annular fabric spreading device. At the same time, the positioning block and the groove have the technical effect of simple structure, thereby reducing the technical effect of reducing the manufacturing difficulty of the positioning unit, and thus achieving the technical effect of improving the design simplicity of the vertical annular fabric spreading device.

[0127] Alternatively, the first positioning structure can be a groove, and the second positioning structure can be a positioning block.

[0128] Of course, in other embodiments, the specific structures of the first positioning structure and the second positioning structure may be adjusted according to the different designs of the vertical annular fabric device.

[0129] In other embodiments, depending on the design of the vertical annular fabric device, the vertical annular fabric device may not include a positioning unit.

[0130] According to an embodiment of the present invention, in a second aspect, a vertical annular mineral processing machine is also provided, comprising:

[0131] The vertical circular fabric feeding device of this embodiment.

[0132] The sorting device is spaced at the bottom of the vertical circular fabric conveyor and is used to receive the materials conveyed by the vertical circular fabric conveyor and sort the materials according to their quality.

[0133] The sorting device includes a vibrating plate 6, which is spaced at the bottom of the vertical annular fabric feeding device. The vibrating plate 6 has a buffer surface 603, a conveying surface 604, and a stabilizing surface 605 connected in sequence from the center to the edge. The buffer surface 603, the conveying surface 604, and the stabilizing surface 605 are all annular in shape, and their heights gradually decrease. The buffer surface 603 is used to buffer the material so that the speed at which the material enters the conveying surface 604 from the buffer surface 603 is zero. The conveying surface 604 has a first part 6041 near the buffer surface 603 and a second part 6042 near the stabilizing surface 605. The first part 6041 has a first angle with the horizontal plane, and the second part 6042 has a second angle with the horizontal plane. The first angle is greater than the second angle.

[0134] The vibratory feeder 6 can be used to adjust the movement speed of the material. Specifically, the material can first fall on the buffer surface 603, and then move along the buffer surface 603, the conveying surface 604 and the stabilizing surface 605 in sequence. Since the buffer surface 603, the conveying surface 604 and the stabilizing surface 605 are all annular, a large amount of material can fall along the buffer surface 603, the conveying surface 604 and the stabilizing surface 605 in an annular manner until it leaves the vibratory feeder 6, thereby ensuring the amount of material distributed.

[0135] During the fabric feeding process, the buffer surface 603 can receive the material undergoing free fall and decelerate it, reducing the initial velocity of the material when it enters the conveying surface 604. This ensures that the material's velocity is zero when it reaches the conveying surface 604. While on the conveying surface 604, the material can move linearly along the surfaces of the first part 6041 and the second part 6042. Since the angle of the first part 6041 is greater than that of the second part 6042, the acceleration of the material in the first part 6041 is greater than that in the second part 6042. Therefore, the first part 6041 can accelerate the material's speed, allowing it to quickly pass through the conveying surface 604. The second part 6042 can slow down the material's acceleration, ensuring that the material's velocity when leaving the vibrating plate 6 meets preset requirements. This not only reduces the time it takes for the material to pass through the conveying surface 604 but also slows down its acceleration, allowing for control over the material's velocity when it enters the stable surface 605. In this embodiment, the preset requirement is that the material can undergo free fall when leaving the stable surface 605, facilitating subsequent material inspection and impurity removal.

[0136] With this configuration, the vibratory feeder 6 in this embodiment can increase the amount of material dispensed through the cooperation of the buffer surface 603, the conveying surface 604 and the stabilizing surface 605, and can also effectively control the speed at which the material enters the detection and impurity removal stages, thereby improving the accuracy of detection and impurity removal and thus improving the sorting effect.

[0137] Of course, in other embodiments, depending on the design of the vibratory feeder 6, the speed and direction of the ore material leaving the stable surface 605 can be adjusted according to the preset requirements.

[0138] In this embodiment, the vibratory plate 6 can be made of manganese steel and the surface roughness of the vibratory plate 6 is 6.3μm. This setting can ensure that the material can move stably along the surface of the vibratory plate 6 and also control the movement speed of the material.

[0139] In this embodiment, the velocity of the material leaving the stable surface 605 is 0.13 m / s to 0.25 m / s.

[0140] After extensive experimental verification, the applicant found that when the speed of the material leaving the stable surface 605 is less than 0.13 m / s, the amount of material dispensed decreases, reducing sorting efficiency. When the speed of the material leaving the stable surface 605 is greater than 0.25 m / s, the sorting accuracy decreases. The applicant discovered that this is because the horizontal speed of the material is too high, causing the material to move in a parabolic motion when leaving the vibrating plate 6. This causes some material to deviate from the effective working area of ​​the downstream detection device and the impurity removal device. Therefore, the applicant determined the speed range of the material leaving the stable surface 605 to be between 0.13 m / s and 0.25 m / s. This ensures that the trajectory of the material leaving the vibrating plate 6 is close to free fall in the vertical direction, reducing the tendency of the material to move in a parabolic motion, so that the material can fall directly into the effective detection area of ​​the downstream detection device and the effective working area of ​​the impurity removal device.

[0141] Combination Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the center of the vibratory feeder 6 has a platform surface 602, which is used to install the vibrator 10. The vibrator 10 can drive the vibratory feeder 6 to vibrate, thereby causing the ore raw material to move radially on the surface of the vibratory feeder 6, so as to avoid the material accumulating on the vibratory feeder 6 and causing jamming. At the same time, the vibrator 10 can also increase the speed of material movement 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 vibratory feeder 6 driven by the vibrator 10 is 50HZ.

[0142] After extensive experimental verification, the applicant found that the faster the vibration frequency of the vibratory plate 6, the faster the material moves on the vibratory plate 6 and the shorter the time it takes to pass through the vibratory plate 6. However, when the vibration frequency is greater than 50 Hz, the motor of the vibrator 10 is at risk of overheating and damage. Therefore, setting the vibration frequency of the vibratory plate 6 to 50 Hz greatly shortens the time it takes for the material to pass through the vibratory plate 6 and also ensures the safety of the vibrator motor during use.

[0143] Combination Figure 14As shown, in this embodiment, the buffer surface 603 and the conveying surface 604 are connected 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 plate 6 changes regularly, forming a first gap with a periodically changing size. The distance between the second baffle device 8 and the vibrating plate 6 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 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 enters the first part 6041 through the first gap. 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 enters the second part 6042 through the second gap. This is because the material undergoes free fall before entering the buffer surface 603, resulting in a relatively high speed. The first baffle device 7 can slow down the material's speed, providing initial control. The first section 6041 allows the material to accelerate and quickly pass through the conveying surface 604. The second baffle device 8 can slow down the material's speed when entering the second section 6042, facilitating speed control within the second section 6042. Furthermore, with the cooperation of the vibrator 10, it ensures that the subsequent material's speed when leaving the stable surface 605 is between 0.13 m / s and 0.25 m / s.

[0144] In one embodiment of this example, the first baffle device 7 and the second baffle device 8 can be baffle curtains. The cross-sectional shape of the baffle curtains can be annular. The radial dimensions of the two baffle curtains are different so as to cooperate with the corresponding positions of the vibrating plate 6. A gap is formed between the open end of the baffle curtain and the vibrating plate 6 to allow material to pass through.

[0145] Combination Figure 5 , Figure 6 and Figure 7As shown, in this embodiment, the angle between the first part 6041 and the horizontal plane ranges from 20 degrees to 55 degrees, and the angle between the second part 6042 and the horizontal plane ranges from 15 degrees to 25 degrees. The applicant demonstrated through experiments that when the angle of the first part 6041 is less than 20 degrees, the material movement speed will be too slow, reducing the speed of the material passing through the vibrating plate 6. When the angle of the first part 6041 is greater than 55 degrees, the material movement speed will be too fast, and it will be difficult to control the final speed of the material leaving the vibrating plate 6 through the second part 6042. The second part 6042 is set between 15 and 25 degrees, for example, it can be 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 or 25 degrees, or it can include non-integer angles. When the angle of the second part 6042 is larger, the material passes through in a shorter time and the speed is faster, but it can still meet the requirement of not exceeding the maximum speed of 0.25 m / s. With this setting, the second part 6042 can work with the surface roughness and vibration frequency of the vibrating plate 6 to control the material to move at a uniform speed or to move slowly and accelerate. It can control the speed of the material when it leaves the edge of the vibrating plate 6 to be within the range of 0.13 m / s to 0.25 m / s.

[0146] To increase the material dispensing capacity, the distance for material movement on the vibratory feeder 6 needs to be increased. Based on this, the outer diameter of the vibratory feeder 6 can be adjusted according to the actual structure to ensure that the distance and angle between the first part 6041 and the second part 6042 are matched to meet the material dropping speed requirements. However, considering that the speed of material movement on the surface of the vibratory feeder 6 is not only related to the angle between the first part 6041 and the second part 6042, but also to the distance the material moves on the first part 6041 and the second part 6042, the applicant conducted a large number of experiments and obtained the following two sets of experimental data under the condition that the speed of material leaving the vibratory feeder 6 is 0.13m / s to 0.25m / s. The vibration frequency of the vibratory feeder 6 in both sets of experimental data is 50HZ.

[0147] Combination Figure 5 , Figure 6 and Figure 7As shown, in one embodiment of this example, the distance range for material movement provided by the first part 6041 and the second part 6042 is 300mm to 320mm. Specifically, the distance of the first part 6041 is 147mm to 169mm, and the distance of the second part 6042 is 151mm to 153mm. 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 extensive experimental verification, the applicant has demonstrated that when the total distance between the first part 6041 and the second part 6042 is 300mm to 320mm, it can both ensure that the material passes through the vibrating plate 6 quickly and effectively control the speed of the material when it leaves the vibrating plate 6.

[0148] Furthermore, the applicant discovered that the distance between the first part 6041 and the second part 6042 is not proportional. With the cooperation of the second baffle device 8, the second part 6042 has a greater impact on the final speed. Therefore, after extensive experimental demonstration, the applicant found that when the distance between the first part 6041 and the second part 6042 for the movement of ore raw materials is in the range of 300mm to 320mm, setting the angle of the second part 6042 to 15 degrees to 25 degrees and setting the distance of the second part 6042 to 151mm to 153mm can meet the control of the final speed. To control the movement 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 too slow, which is not conducive to the material passing through the vibrating plate 6 quickly. When the angle of the first part 6041 is greater than 40 degrees, the material speed will be too fast, which is not conducive to the control of the material speed by the first part 6041. 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 147mm to 169mm. For example, the distance of the second part 6042 is 151mm, and the distance of the first part 6041 can be 149mm to 169mm, or... The distance between the second part 6042 and the first part 6041 is 152mm, and the distance between them is 148mm to 168mm. Alternatively, the distance between the second part 6042 and the first part 6041 is 153mm, and the distance between them is 147mm to 167mm. Other combinations are also possible, but they will not be listed here. With this configuration, the material can accelerate when the first part 6041 is vibrated, allowing it to pass through the first part 6041 quickly. When the second part 6042 is vibrated, the material moves in a uniform linear motion or accelerates slowly, so that the speed at which the material leaves the stable surface 605 is within the range of 0.13m / s to 0.25m / s.

[0149] Preferably, the distance range for material movement provided by the first part 6041 and the second part 6042 is 300mm to 320mm, wherein the distance of the first part 6041 is 147mm to 169mm, the distance of the second part 6042 is 151mm to 153mm, 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 ensures that the material passes through the vibrating plate 6 quickly and that the speed of the material leaving the vibrating plate 6 can be well controlled.

[0150] In this embodiment, the outer diameter of the vibratory plate 6 is selected from 1200mm to 1600mm. The outer diameter of the vibratory plate 6 used in the experiment is 1460mm. The outer diameter of the vibratory plate 6 can be selected according to the actual structure of the mineral processing machine. That is, it can be increased or decreased based on the above range, as long as the distance and angle of the first part 6041 and the second part 6042 are properly matched.

[0151] Combination Figure 8 , Figure 9 and Figure 10 As shown, in another embodiment of this example, the distance range for material movement provided by the first part 6041 and the second part 6042 is 430mm to 450mm, wherein the distance of the first part 6041 is 176mm to 198mm, the distance of the second part 6042 is 252mm to 254mm, 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 extensive experimental verification, the applicant has demonstrated that when the outer diameter of the vibratory feeder 6 is 1680mm, and the total distance between the first part 6041 and the second part 6042 is 430mm to 450mm, it can both ensure that the material passes through the vibratory feeder 6 quickly and effectively control the speed at which the material leaves the vibratory feeder 6.

[0152] Furthermore, through data comparison, the applicant discovered that when the material movement distance on the vibratory feeder 6 is different, there is no proportional relationship between the first part 6041 and the second part 6042. When the distance of the ore material movement supplied by the first part 6041 and the second part 6042 is in the range of 430mm to 450mm, the second part 6042 has a greater impact on the final speed with the cooperation of the second baffle device 8. Therefore, after extensive experimental demonstration, the applicant found that setting the angle of the second part 6042 to 15 degrees to 25 degrees and the distance of the second part 6042 to 252mm to 254mm can meet the requirements for controlling the final speed. To control the movement 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 35 degrees, the speed will be too slow, which is not conducive to the material passing through the vibrating plate 6 quickly. When the angle of the first part 6041 is greater than 55 degrees, the material speed will be too fast, which is not conducive to the control of the material speed by the first part 6041. 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 176mm to 198mm. For example, if the distance of the second part 6042 is 252mm, the distance of the first part 6041 can be 178mm to 198mm, or... The distance between the second part 6042 and the first part 6041 is 253mm, and the distance between them is 177mm to 197mm. Alternatively, the distance between the second part 6042 and the first part 6041 is 254mm, and the distance between them is 176mm to 196mm. Other combinations are also possible, but they will not be listed here. With this configuration, the material can accelerate when the first part 6041 is vibrated, allowing it to pass through the first part 6041 quickly. When the second part 6042 is vibrated, the material moves in a uniform linear motion or accelerates slowly, so that the speed at which the material leaves the stable surface 605 is within the range of 0.13m / s to 0.25m / s.

[0153] Preferably, the distance range for material movement provided by the first part 6041 and the second part 6042 is 430mm to 450mm, wherein the distance of the first part 6041 is 176mm to 198mm, the distance of the second part 6042 is 252mm to 254mm, 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. This ensures that the material passes through the vibrating plate 6 quickly and that the speed of the material leaving the vibrating plate 6 can be well controlled.

[0154] In this embodiment, the outer diameter of the vibratory plate 6 is selected from 1500mm to 2000mm. The outer diameter of the vibratory plate 6 used in the experiment is 1680mm. The outer diameter of the vibratory plate 6 can be selected according to the actual structure of the mineral processing machine. That is, it can be increased or decreased based on the above range, as long as the distance and angle of the first part 6041 and the second part 6042 are properly matched.

[0155] Combination Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the buffer surface 603 is an inclined plane. 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 actual structural needs. The stabilizing surface 605 is parallel to the horizontal plane and can guide the movement trajectory of the material. Before entering the stabilizing surface 605, the material moves along the angle of the second part 6042. In order to avoid the material from making oblique projectile motion, the stabilizing surface 605 can first guide the material to move in the horizontal direction. With the material's movement speed range of 0.13m / s to 0.25m / s, the material can fall within the effective range of the detection device and the impurity removal device when it leaves the stabilizing surface 605.

[0156] Combination Figure 11 As shown, in this embodiment, an arc-shaped guide surface 6051 is provided at one end of the stabilizing surface 605 away from the conveying surface 604. The arc-shaped guide surface 6051 is used to guide the material to move along the height direction. After the material leaves the stabilizing surface 605, it can move along the arc-shaped guide surface 6051, thereby making free landing movement in the height direction, which facilitates entering the effective range of the downstream detection device and impurity removal device.

[0157] Combination Figure 7 and Figure 12 As shown, the vibratory feeder 6 is funnel-shaped. A buffer surface 603, a conveying surface 604, and a stabilizing surface 605 are disposed on the convex surface of the vibratory feeder 6. Multiple strip-shaped reinforcing ribs 608 are evenly distributed on the concave surface of the vibratory feeder 6, extending from the center to the edge. For example, ten strip-shaped reinforcing ribs 608 can be disposed on the concave surface of the vibratory feeder 6, thereby improving the structural strength and impact resistance of the vibratory feeder 6. Annular reinforcing ribs 609 can be disposed at the edge of the concave surface of the vibratory feeder 6. For example, two annular reinforcing ribs 609 can be disposed on the concave surface of the vibratory feeder 6, located near the center and near the edge, respectively, thereby further improving the structural strength of the vibratory feeder 6.

[0158] Combination Figure 12As shown, multiple mounting positions 6010 are provided on the concave surface edge of the vibratory plate 6. The mounting positions 6010 can be used to connect with the bracket 11 of the mineral processing machine, for example, by means of a rubber spring.

[0159] Combination Figure 6 As shown, in one embodiment of this example, a first stepped surface 606 is provided between the buffer surface 603 and the conveying surface 604. Since the vibratory plate 6 needs to be equipped with the vibrator 10 and cooperate with the fabric feeding device, the height dimension of the vibratory plate 6 has requirements. The first stepped surface 606 can serve to connect the buffer surface 603 and the conveying surface 604. For example, when the distance range for the movement of ore raw materials on the first part 6041 and the second part 6042 on the vibratory plate 6 is 300mm to 320mm, the first stepped surface 606 has a good transition connection effect because the angle of the first part 6041 is 20 degrees to 40 degrees.

[0160] Combination Figure 9 As shown, when the distance range for the movement of ore raw materials on the first part 6041 and the second part 6042 on the vibratory plate 6 is 430mm to 450mm, the angle of the first part 6041 is 35 degrees to 55 degrees. There is no need to set the first step surface 606 on the vibratory plate 6. The connection with the buffer surface 603 can be formed by relying on the angle and distance of the first part 6041.

[0161] Combination Figure 6 As shown, in one embodiment of this example, the stabilizing surface 605 is provided with a second stepped surface 607 at the edge away from the conveying surface 604. Since the vibrating plate 6 has a certain thickness, the second stepped surface 607 can prevent the material from making secondary contact with the vibrating plate 6 when it leaves the arc-shaped guide surface 6051.

[0162] Combination Figure 13 , Figure 14 and Figure 15 As shown, the sorting device includes a frame 9 and a vibrator 10.

[0163] The vibratory feeder 6 is mounted on the frame 9 via a bracket 11. The vibrator 10 is positioned at the center of the vibratory feeder 6 to provide excitation force. The frame 9 is connected to the base 1. The vibrator 10 is mounted on the frame 9 via the bracket 11. The vibratory feeder 6 faces the material cylinder 2 and is used to receive material from the material cylinder 2. For example, after passing through the material cylinder 2, the material falls onto the vibratory feeder 6. The excitation force of the vibrator 10 drives the vibratory feeder 6 to vibrate, causing the material to fall evenly along the annular surface of the vibratory feeder 6, facilitating detection and impurity removal by the detection and removal devices below.

[0164] Combination Figure 15As shown, the lower surface of the vibratory feeder 6 is connected to the support 11 via multiple elastic support columns 12. When the vibrator 10 is working, the vibratory feeder 6 can vibrate relative to the support 11 via the elastic support columns 12, preventing the excitation force from being transmitted to the support 11. The elastic support columns 12 can be made of rubber or silicone material and have a hollow inner cavity. A first fastener 13 and a second fastener 14 are respectively provided at both ends of the hollow inner cavity. The first fastener 13 is connected to the vibratory feeder 6, and the second fastener 14 is connected to the support 11 to ensure that the vibratory feeder 6 can vibrate relative to the support 11. The first fastener 13 and the second fastener 14 have the same structure, both including inserts that can be embedded in the hollow inner cavity and screws provided on the inserts. The screws are used to tighten into the corresponding threaded holes on the vibratory feeder 6 or the support 11.

[0165] The elastic support column 12 can also be replaced with a rubber spring.

[0166] The bracket 11 can be mounted on the frame 9 via a support frame. The support frame 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 vibratory plate 6 and the support frame, so that the material can fall through the gap for subsequent inspection and impurity removal.

[0167] The vibratory plate 6 has a second through hole 601 at its center. The vibratory plate 6 can serve as a material receiving and conveying structure. The vibratory plate 6 can be made of manganese steel. The vibration of the vibratory plate 6 can be controlled by the vibrator 10, so that the material moves radially on the surface of the vibratory plate 6.

[0168] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
