Description

Technical Field

[0001] The present invention relates to the field of cleaning technology, in particular to a cleaning device and a mineral processing machine for a vertical annular material distribution structure. Background Art

[0002] The existing ore dressing machine that screens and separates mixed high-quality ore and low-quality ore is to put the mixed ore into the screening device through the distribution device, and then use the X-ray in the screening device to separate the high-quality ore and low-quality ore and store them. Specifically, the ore dressing machine includes:

[0003] The material distribution device is a conveyor belt structure, arranged in the horizontal direction, and is used to transport mixed ore;

[0004] The screening device is located downstream of the material distribution device and on one side of the material distribution device, and is used to receive the mixed ore transmitted by the material distribution device and separate the mixed ore through the laser in the screening device;

[0005] The cleaning device includes a linear module and a scraper. The linear module drives the scraper to extend and retract along the transmission direction perpendicular to the distribution device, so that the scraper can clean the residual ore on the distribution device to prevent the residual ore from affecting the accuracy of mixed ore screening on the distribution device.

[0006] Because the material distribution device and screening device are arranged flat, the ore dressing machine occupies a large space. Therefore, existing ore dressing machines stack the screening device and the material distribution device, and both the screening device and the material distribution device are configured as a vertical ring structure to reduce the space occupied by the ore dressing machine. However, when the surface of the screening device in such ore dressing machines needs to be cleaned, the existing cleaning device cannot be used for cleaning, and the cleaning process must be carried out manually, which not only increases labor costs but also reduces cleaning efficiency. Summary of the Invention

[0007] In light of this, the present invention provides a cleaning device for a vertical annular distribution structure and a mineral processing machine. This solves the problem that existing mineral processing machines stack the screening device and the distribution device, both of which are configured as vertical annular structures to reduce the space occupied by the mineral processing machine. However, when the surface of the screening device in such mineral processing machines needs to be cleaned, it is usually done manually, which not only increases labor costs but also reduces cleaning efficiency.

[0011] Beneficial effect: By setting up a cleaning unit that contacts the surface of the workpiece to be cleaned, the cleaning unit can clean the surface of the workpiece to be cleaned during the rotation process, so that the cleaning device can be suitable for vertical annular workpieces to be cleaned without manual operation, which not only saves labor costs but also achieves the technical effect of improving cleaning efficiency.

[0012] In an optional embodiment, the cleaning unit includes:

[0013] a driving structure connected to the first base;

[0014] The cleaning structure is connected to the driving structure. Under the drive of the driving structure, the cleaning structure rotates around its own axis.

[0016] In an optional embodiment, the driving structure includes:

[0017] A driving unit, provided on the first base;

[0018] a speed reducing unit connected to both the driving unit and the cleaning structure, and configured to reduce the rotation speed of the cleaning structure;

[0019] And / or, the cleaning structure includes:

[0020] a second base connected to the driving structure;

[0021] The cleaning part has one end connected to the second base and the other end used to contact the object to be cleaned.

[0022] Beneficial effect: Through the cooperation between the driving part and the speed reduction part, the rotation speed of the cleaning structure can be adjusted as needed, thereby achieving the technical effect of improving the convenience of adjusting the cleaning speed of the cleaning device, and further achieving the technical effect of improving the convenience of using the cleaning device;

[0023] By arranging the cleaning part on the second base, the cleaning part can rotate along with the second base, thereby avoiding blind spots in cleaning and improving the cleaning effect of the cleaning part on the object to be cleaned.

[0032] Beneficial effect: By providing the first rotating part and the second rotating part, the first rotating part can rotate along with the deceleration part, and the cleaning structure is driven to rotate around its own axis through the second rotating part, thereby achieving a cleaning operation on the object to be cleaned;

[0033] Due to the elasticity of the first elastic portion, when there is a positional deviation between the cleaning portion and the object to be cleaned, the first elastic portion flexibly corrects the position of the object to be cleaned, so that the cleaning portion always fits the object to be cleaned, thereby achieving the technical effect of improving the cleaning reliability of the cleaning structure, preventing the cleaning device from failing to clean the surface of the object to be cleaned, and thus improving the cleaning effect of the cleaning device;

[0034] By providing a mating portion that is slidably connected to the cleaning body, when the surface of the object to be cleaned is an inclined surface and the inclination angle of the surface varies, for example, the inclined surface is divided into two sections along the height direction, each with a different inclination angle. In this case, due to the different pressures applied to each mating portion by each section of the inclined surface, the lengths of each mating portion within the receiving groove are different, ensuring that each mating portion is in constant contact with the surface to be cleaned. Based on this, the cleaning device can adapt to inclined surfaces of different angles, thereby achieving the technical effect of improving its applicability to different objects to be cleaned.

[0045] Beneficial effect: By limiting the vibration disk to include at least two layers of vibration inclined surfaces, and at the same time providing at least two layers of cleaning parts, and the positions of the cleaning parts and the vibration inclined surfaces correspond one to one, each layer of cleaning parts can clean the surface of each vibration inclined surface, thereby achieving the technical effect of improving the comprehensiveness of the cleaning of the vibration inclined surfaces.

[0046] In an optional embodiment, the ore dressing machine comprises:

[0047] A material blocking device is provided above the vibrating inclined plane and is spaced apart from the vibrating inclined plane along the radial direction of the cleaning portion. The material blocking device is connected to the second base and is used to slow down the falling speed of the material.

[0048] Beneficial effect: By setting up a material blocking device, it is convenient to slow down the falling speed of the material as needed, and by connecting the material blocking device to the second base, the material blocking device can rotate with the cleaning part, avoiding the situation where the cleaning part rotates when the material blocking device is stationary and the material blocking device is lifted up, thereby achieving the technical effect of improving the reliability of the use of the material blocking device.

[0049] In an optional embodiment, the material blocking device is flexible.

[0050] Beneficial Effect: By limiting the flexibility of the retaining device, the material can pass through the gap between the retaining device and one vibrating inclined surface and enter the next vibrating inclined surface. Alternatively, after the ore concentrator screens out the inferior ore, it drives the inferior ore through the retaining device and out of the ore concentrator, completing the screening of the superior and inferior ore.

[0081] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0082] The following combination Figures 1 to 16 , describing embodiments of the present invention.

[0083] According to an embodiment of the present invention, in a first aspect, a cleaning device for a vertical annular material distribution structure is provided, which is suitable for installation on a concentrator for a vertical annular material distribution structure and includes:

[0084] First base 1.

[0085] The cleaning unit 2 is rotatably connected to the first base 1. The cleaning unit 2 is arranged on one side of the vertical annular object to be cleaned and contacts the object to be cleaned. The cleaning unit 2 is used to rotate to clean the surface of the object to be cleaned.

[0086] In the cleaning device of this embodiment, a cleaning unit 2 is provided that contacts the surface of the workpiece to be cleaned, so that the cleaning unit 2 can clean the surface of the workpiece to be cleaned during rotation, so that the cleaning device can be suitable for vertical annular workpieces to be cleaned without the need for manual operation, which not only saves labor costs but also achieves the technical effect of improving cleaning efficiency.

[0087] Wherein, in this embodiment, the cleaning unit 2 is arranged on the top of the object to be cleaned. Of course, in other embodiments, the position between the cleaning unit 2 and the object to be cleaned is adjusted according to the design of the cleaning device.

[0088] In addition, combined Figure 2 As shown, in this embodiment, the cleaning unit 2 includes:

[0089] The driving structure 201 is connected to the first base 1 .

[0090] The cleaning structure 202 is connected to the driving structure 201 and is configured to rotate around its own axis when driven by the driving structure 201 .

[0091] By providing the driving structure 201, the cleaning structure 202 can be driven to rotate without manual operation, which not only saves labor costs but also achieves the technical effect of improving cleaning efficiency.

[0092] Further, combined with Figure 5 As shown, in this embodiment, the driving structure 201 includes:

[0093] The driving part 2011 is disposed on the first base 1 , that is, the fixed end of the driving part 2011 is disposed on the first base 1 .

[0094] The speed reduction unit 2012 is connected to both the driving unit 2011 and the cleaning structure 202, and is used to reduce the rotational speed of the cleaning structure 202. Based on this, through the cooperation between the driving unit 2011 and the speed reduction unit 2012, the rotational speed of the cleaning structure 202 can be adjusted as needed, thereby achieving the technical effect of improving the ease of adjusting the cleaning speed of the cleaning device, and further achieving the technical effect of improving the ease of use of the cleaning device.

[0095] The driving part 2011 is a motor, and the speed reduction part 2012 is a speed reducer;

[0096] Specifically, combined Figure 5 As shown, the driving structure 201 includes:

[0097] The first rotating portion 2013 is connected to the speed reduction portion 2012 and is configured to rotate along with the speed reduction portion 2012 .

[0098] The second rotating part 2014 is in transmission connection with the first rotating part 2013 . The second rotating part 2014 is connected to the cleaning structure 202 and is used to drive the cleaning structure 202 to rotate around its own axis so that the cleaning structure 202 can clean the surface of the object to be cleaned.

[0099] The first rotating part 2013 is a gear, and the second rotating part 2014 is a ring gear. The structure of the gear and the ring gear is simple, thereby achieving the technical effect of improving the simplicity of the cleaning device design. At this time, the second rotating part 2014 is meshed with the first rotating part 2013.

[0100] Furthermore, the driving part 2011 has forward and reverse rotation functions, and the cleaning unit 2 includes:

[0101] The sensing structure is provided on the first base 1 and is used to monitor the surface treatment condition of the cleaning object and upload the monitoring result.

[0102] The control structure is in communication with the sensor structure, and is used to receive the monitoring results uploaded by the sensor structure, and control the forward and reverse rotation of the driving part 2011 according to the monitoring results, thereby achieving the technical effect of improving the intelligence of the use of the cleaning device.

[0103] Of course, in other embodiments, the types of the driving portion 2011 , the speed reduction portion 2012 , the first rotating portion 2013 and the second rotating portion 2014 are adjusted according to different designs of the cleaning device.

[0104] In other embodiments, depending on the design of the cleaning device, the cleaning unit 2 may only include the cleaning structure 202 .

[0105] Meanwhile, in other embodiments, the specific structure of the driving structure 201 is selected according to different designs of the cleaning device.

[0106] In addition, combined Figure 3 As shown, in this embodiment, the cleaning structure 202 includes:

[0107] The second base 2021 is connected to the driving structure 201 , that is, connected to the driving part 2011 .

[0108] The cleaning portion 2022 has one end connected to the second base 2021 and the other end used to contact the object to be cleaned.

[0109] By arranging the cleaning portion 2022 on the second base 2021 , the cleaning portion 2022 can rotate along with the second base 2021 , thereby avoiding blind spots in cleaning and improving the cleaning effect of the cleaning portion 2022 on the object to be cleaned.

[0110] Furthermore, the cleaning structure 202 includes:

[0111] One end of the first elastic portion 2023 is connected to the cleaning portion 2022, and the other end of the first elastic portion 2023 is connected to the second base 2021. Based on this, due to the elasticity of the first elastic portion 2023, when there is a positional deviation between the cleaning portion 2022 and the object to be cleaned, or when the surface of the object to be cleaned is uneven due to dirt and compaction, the first elastic portion 2023 flexibly corrects the position of the object to be cleaned, so that the cleaning portion 2022 always fits the object to be cleaned, thereby achieving the technical effect of improving the cleaning reliability of the cleaning structure 202, preventing the cleaning device from failing to clean the surface of the object to be cleaned, and thus improving the cleaning effect of the cleaning device.

[0112] For example, when the workpiece to be cleaned applies pressure to the cleaning portion 2022, pressure is also applied to the first elastic portion 2023, so that the first elastic portion 2023 is in a compressed state. Under the action of the elastic force, the first elastic portion 2023 drives the cleaning portion 2022 to always be in contact with the workpiece to be cleaned, thereby achieving the technical effect of improving the contact tightness between the cleaning portion 2022 and the workpiece to be cleaned, and further achieving the technical effect of improving the cleaning efficiency of the cleaning portion 2022 on the workpiece to be cleaned.

[0113] In this embodiment, the first elastic portion 2023 is a spring.

[0114] Of course, in other embodiments, the specific structure of the first elastic portion 2023 is adjusted according to different designs of the cleaning device.

[0115] As an alternative embodiment, the cleaning structure 202 may not include the first elastic portion 2023 .

[0116] In addition, in this embodiment, the cleaning unit 2022 includes:

[0117] The cleaning body has a receiving groove on its surface that contacts the object to be cleaned.

[0118] There are multiple matching parts, which are arranged in the receiving groove and slidably connected to the cleaning part 2022. The matching parts are in contact with the object to be cleaned and are used to match the object to be cleaned at various tilt angles.

[0119] By providing a mating portion that is slidably connected to the cleaning body, when the surface of the object to be cleaned is an inclined surface and the inclination angle of the surface varies, for example, the inclined surface is divided into two sections along the height direction, each with a different inclination angle. In this case, due to the different pressures applied to each mating portion by each section of the inclined surface, the lengths of each mating portion within the receiving groove are different, ensuring that each mating portion is in constant contact with the surface to be cleaned. Based on this, the cleaning device can adapt to inclined surfaces of different angles, thereby achieving the technical effect of improving its applicability to different objects to be cleaned.

[0120] Furthermore, the cleaning unit 2022 includes:

[0121] There are multiple second elastic parts, and the number of second elastic parts corresponds to the number of matching parts. One end of the second elastic part is connected to the inner wall of the accommodating groove, and the other end of the second elastic part is connected to the matching part.

[0122] By providing the second elastic portion, when the inclined surface applies pressure to the mating portion, the second elastic portion is in a compressed state. Under the action of the elastic force, the second elastic portion drives the mating portion to always be in contact with the object to be cleaned, thereby improving the technical effect of improving the contact tightness between the mating portion and the object to be cleaned, and further achieving the technical effect of improving the cleaning efficiency of the mating portion on the object to be cleaned.

[0123] The second elastic portion is a spring, and the matching portion is a block structure.

[0124] Of course, in other embodiments, depending on the design of the cleaning device, the cleaning structure 202 does not include the second elastic portion, and the object to be cleaned applies pressure to the mating portion to achieve length adjustment of the mating portion in the receiving groove.

[0125] In other embodiments, the specific structure of the second elastic portion and the shape of the matching portion are adjusted according to different designs of the cleaning device.

[0126] Of course, in other embodiments, depending on the design of the cleaning device, the driving structure 201 is limited to only include the driving part 2011 and the speed reduction part 2012 , or the cleaning structure 202 is limited to only include the second base 2021 and the cleaning part 2022 .

[0127] According to an embodiment of the present invention, in a second aspect, a concentrator for a vertical annular material distribution structure is provided for screening materials. The concentrator comprises:

[0128] The specific structure of the cleaning device for the vertical annular cloth structure introduced above will not be repeated here.

[0129] The vibration device 3 is arranged below the cleaning device. The vibration device 3 is in contact with the cleaning device and is used as the object to be cleaned. The vibration device 3 is used to screen the material.

[0130] In this embodiment, the cleaning device is arranged above the vibration device 3. Of course, in other embodiments, the relative position between the cleaning device and the vibration device 3 is adjusted according to the design of the ore dressing machine.

[0131] Furthermore, in this embodiment, the material is a mixture of superior ores and inferior ores.

[0132] Of course, in other embodiments, the type of material is adjusted according to different usage scenarios of the ore dressing machine.

[0133] In addition, in this embodiment, the excitation device 3 includes a vibration plate 301 , which is disposed on the bottom surface of the cleaning portion 2022 and contacts the cleaning portion 2022 .

[0134] The sorting device includes a vibration plate 301, which is spaced apart at the bottom of the vertical annular material distribution device, and the vibration plate 301 includes at least two layers of vibration inclined surfaces.

[0135] Specifically, the vibration disk 301 is provided with a connected buffer surface 3013, a conveying surface 3014 and a stabilizing surface 3015 in sequence from the center to the edge. The buffer surface 3013, the conveying surface 3014 and the stabilizing surface 3015 are all annular in shape, and the heights of the buffer surface 3013, the conveying surface 3014 and the stabilizing surface 3015 gradually decrease. The buffer surface 3013 is used to buffer the material so that the speed of the material entering the conveying surface 3014 from the buffer surface 3013 is zero. The conveying surface 3014 has a first part 30141 close to the buffer surface 3013 and a second part 30142 close to the stabilizing surface 3015, that is, the first part 30141 and the second part 30142 are vibration inclined surfaces, and there is a first angle between the first part 30141 and the horizontal plane, and there is a second angle between the second part 30142 and the horizontal plane, and the first angle is greater than the second angle.

[0136] Among them, the vibration disk 301 can be used to adjust the movement speed of the material. Specifically, the material can first fall on the buffer surface 3013, and then move in sequence along the buffer surface 3013, the conveying surface 3014 and the stabilizing surface 3015. Since the shapes of the buffer surface 3013, the conveying surface 3014 and the stabilizing surface 3015 are all ring-shaped, a large amount of material can fall in a ring-shaped manner along the buffer surface 3013, the conveying surface 3014 and the stabilizing surface 3015 until it leaves the vibration disk 301, thereby ensuring the material distribution amount.

[0137] During the material distribution process, the buffer surface 3013 can receive the material in free fall and decelerate it, reducing the initial velocity of the material when it enters the conveying surface 3014, so that the material's velocity is zero when it moves on the conveying surface 3014. When the material moves on the conveying surface 3014, it can move in a straight line along the surfaces of the first portion 30141 and the second portion 30142. Because the angle of the first portion 30141 is greater than the angle of the second portion 30142, the acceleration of the material in the first portion 30141 is greater than the acceleration of the material in the second portion 30142. Therefore, the first portion 30141 can be used to accelerate the speed of the material, allowing the material to pass through the conveying surface 3014 quickly, while the second portion 30142 can be used to slow down the acceleration trend of the material, so that the speed of the material when it leaves the vibrating plate 301 meets the preset requirements. This not only reduces the time it takes for the material to pass through the conveying surface 3014, but also slows down the acceleration trend of the material, so that the speed of the material when it leaves the conveying surface 3014 and enters the stabilizing surface 3015 can be controlled. In this embodiment, the preset requirement is that the material can perform free fall motion when leaving the stable surface 3015, so as to facilitate subsequent detection and impurity removal of the material.

[0138] With such an arrangement, the vibration plate 301 of this embodiment can increase the amount of material distributed through the cooperation of the buffer surface 3013, the conveying surface 3014 and the stabilizing surface 3015, and can also well control the speed at which the material enters the detection link and the impurity removal link, thereby improving the accuracy of detection and impurity removal, and thus improving the sorting effect.

[0139] Of course, in other embodiments, the speed and direction of the movement of the ore material away from the stable surface 3015 in the preset requirements are adjusted according to different designs of the vibration plate 301 .

[0140] In this embodiment, the vibration disk 301 can be made of manganese steel material, and the surface roughness of the vibration disk 301 is 6.3μm. This setting can ensure that the material can move stably along the surface of the vibration disk 301 while also controlling the movement speed of the material.

[0141] In this embodiment, the speed at which the material leaves the stable surface 3015 is 0.13 m / s to 0.25 m / s.

[0142] After a large number of experiments, the applicant has demonstrated that when the speed of the material leaving the stable surface 3015 is less than 0.13m / s, the material distribution amount will decrease, reducing the sorting efficiency. When the speed of the material leaving the stable surface 3015 is greater than 0.25m / s, the sorting accuracy will decrease. The applicant found that this is because the horizontal speed of the material is too fast, causing the material to leave the vibration disk 301 and perform parabolic motion, which will cause part of the material to deviate from the effective action area of ​​the downstream detection device and the impurity removal device. Therefore, the speed range of the material leaving the stable surface 3015 is determined to be 0.13m / s to 0.25m / s, thereby ensuring that the movement trajectory of the material when leaving the vibration disk 301 is close to free fall in the vertical direction, slowing down the tendency of the material to perform parabolic motion, so that the material can directly fall into the effective detection area of ​​the downstream detection device and the effective action area of ​​the impurity removal device.

[0143] Combine Figure 6 、 Figure 7 and Figure 8 As shown, in this embodiment, the center of the vibration disk 301 has a plane 3012, and the plane 3012 is used to install the exciter 302. The exciter 302 can drive the vibration disk 301 to vibrate, so that the ore raw material moves radially on the surface of the vibration disk 301 to avoid the accumulation of materials on the vibration disk 301 and causing jamming. At the same time, the exciter 302 can also increase the speed of material movement to a certain extent. For example, the plane 3012 is provided with a through hole 3011, and the exciter 302 is installed in the through hole 3011. The vibration frequency of the vibration disk 301 driven by the exciter 302 is 50HZ.

[0144] After a large number of experiments, the applicant has demonstrated that the faster the vibration frequency of the vibration disk 301, the faster the material moves on the vibration disk 301, and the shorter the time it takes to pass through the vibration disk 301. However, when the vibration frequency is greater than 50 Hz, the motor of the exciter 302 is at risk of overheating and damage. Therefore, setting the vibration frequency of the vibration disk 301 at 50 Hz greatly shortens the time it takes for the material to pass through the vibration disk 301, and also ensures the safety of the motor of the exciter during use.

[0145] Combine Figure 15 As shown, the positions of the cleaning parts 2022 and the vibrating inclined planes correspond one to one, and each cleaning part 2022 is arranged in close contact with the vibrating inclined plane.

[0146] Based on this, each layer of cleaning parts 2022 can clean the surface of each vibration slope, which can achieve the technical effect of improving the comprehensiveness of the cleaning of the vibration slope.

[0147] Preferably, the driving part 2011 is provided with a cleaning part 2022, which is set at positions of different diameters of the second base 2021, so that a driving structure 201 can drive the rotation of the cleaning parts 2022 on different diameters, thereby achieving the technical effect of saving energy and further achieving the technical effect of saving the production cost of the ore dressing machine.

[0148] Of course, in other embodiments, the number of driving parts 2011 is adjusted according to different designs of the cleaning device.

[0149] In other embodiments, the number of layers of the vibrating inclined surface and the number of layers of the cleaning portion 2022 are adjusted according to different designs of the cleaning device.

[0150] In addition, combined Figure 2 、 Figure 5 and Figure 15 As shown, in this embodiment, the ore dressing machine includes:

[0151] The material blocking device 4 is arranged above the vibrating inclined plane, and is arranged at intervals along the radial direction of the cleaning part 2022. The material blocking device 4 is connected to the second base 2021, and is used to slow down the falling speed of the material as needed. The connection between the material blocking device 4 and the second base 2021 can enable the material blocking device 4 to rotate with the cleaning part 2022, thereby avoiding the situation where the cleaning part 2022 rotates when the material blocking device 4 is stationary, and the material blocking device 4 is lifted up, thereby achieving the technical effect of improving the reliability of the use of the material blocking device 4.

[0152] Preferably, the retaining device 4 is a flexible structure, for example, made of one or a mixture of wear-resistant rubber, silicone, and polyurethane, allowing the material to pass through the gap between the retaining device 4 and one vibrating inclined surface and enter the next vibrating inclined surface. Alternatively, after the ore concentrator screens out the inferior ore, it is driven through the retaining device 4 and out of the ore concentrator, completing the screening of the superior and inferior ore.

[0153] In this embodiment, the material blocking device 4 is a blocking curtain. Of course, in other embodiments, the specific structure of the material blocking device 4 is adjusted according to the design of the ore dressing machine.

[0154] Specifically, since the vibration inclined surface in this embodiment has two layers, the material blocking device 4 in this embodiment includes a first material blocking structure 401 and a second material blocking structure 402 .

[0155] Of course, in other embodiments, the ore dressing machine may not include the material blocking device 4 .

[0156] Combine Figure 15 As shown, in this embodiment, the buffer surface 3013 and the conveying surface 3014 are matched with the external first blocking structure 401, and the second blocking structure 402 is provided between the first part 30141 and the second part 30142. When the exciter 302 is working, the distance between the first blocking structure 401 and the vibration plate 301 changes regularly, forming a first gap with a periodic change in size, and the distance between the second blocking structure 402 and the vibration plate 301 changes regularly, forming a second gap with a periodic change in size. When the first gap is smaller than the material, the material is blocked by the first blocking structure 401, slowing its speed and ensuring zero speed when it enters the first portion 30141 of the conveying surface 3014. When the first gap is larger than the material, the material passes through the first gap and enters the first portion 30141. When the second gap is smaller than the material, the material is blocked by the second blocking structure 402, slowing its speed. When the second gap is larger than the material, the material passes through the second gap and enters the second portion 30142. This is because the material is in free fall before entering the buffer surface 3013, and its speed is relatively high. The first blocking structure 401 can slow the material speed, providing preliminary control over its speed. The first part 30141 allows the material to accelerate and pass through the conveying surface 3014 quickly. The second material blocking structure 402 can slow down the speed of the material when it enters the second part 30142, so that the second part 30142 can control the speed of the material, and with the cooperation of the exciter 302, ensure that the speed of subsequent materials leaving the stable surface 3015 is 0.13m / s to 0.25m / s.

[0157] In one implementation of this embodiment, the first material blocking structure 401 and the second material blocking structure 402 can be a blocking curtain, the cross-sectional shape of the blocking curtain can be annular, and the radial dimensions of the two blocking curtains are different so as to respectively cooperate with the corresponding positions of the vibration disk 301, and a gap is formed between the open end of the blocking curtain and the vibration disk 301 to allow material to pass through.

[0158] Combine Figure 6 、 Figure 7 and Figure 8 As shown, in this embodiment, the angle between the first part 30141 and the horizontal plane is in the range of 20 to 55 degrees, and the angle between the second part 30142 and the horizontal plane is in the range of 15 to 25 degrees. The applicant has demonstrated through experiments that when the angle of the first part 30141 is less than 20 degrees, the material movement speed will be too slow, reducing the speed of the material passing through the vibration plate 301. When the angle of the first part 30141 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 vibration plate 301 through the second part 30142. The second part 30142 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 therein. When the angle of the second part 30142 is larger, the time for the material to pass through is shorter and the speed is faster, but it can still meet the requirement of not exceeding the maximum speed of 0.25m / s. With this setting, the second part 30142 can cooperate with the surface roughness and vibration frequency of the vibration disk 301 to control the material to move at a uniform speed, or slowly accelerate, and can control the speed of the material when leaving the edge of the vibration disk 301 to be within the range of 0.13m / s to 0.25m / s.

[0159] In order to increase the material distribution amount, it is necessary to increase the size of the vibration plate 301. However, considering that the speed of the material moving on the surface of the vibration plate 301 is not only related to the angle between the first part 30141 and the second part 30142, but also related to the distance the material moves on the first part 30141 and the second part 30142, the applicant has conducted a large number of experimental demonstrations and obtained the following two sets of experimental data while ensuring that the speed of the material leaving the vibration plate 301 is 0.13m / s to 0.25m / s. The vibration frequency of the vibration plate 301 in both sets of experimental data is 50HZ.

[0160] Combine Figure 6 、 Figure 7 and Figure 8As shown, in one embodiment of the present embodiment, the distance range for material movement between the first part 30141 and the second part 30142 is 300mm to 320mm, wherein the distance of the first part 30141 is 147mm to 169mm, and the distance of the second part 30142 is 151mm to 153mm. The angle between the first part 30141 and the horizontal plane is 20 degrees to 40 degrees, and the angle between the second part 30142 and the horizontal plane is 15 degrees to 25 degrees. The applicant has demonstrated through a large number of experiments that when the outer diameter of the vibration plate 301 is 1460mm and the total distance between the first part 30141 and the second part 30142 is 300mm to 320mm, it can not only ensure that the material passes through the vibration plate 301 quickly, but also can well control the speed of the material when leaving the vibration plate 301.

[0161] Furthermore, the applicant found that the distance between the first part 30141 and the second part 30142 has no proportional relationship. With the cooperation of the second blocking structure 402, the second part 30142 has a greater impact on the final speed. Therefore, after a large number of experiments, the applicant demonstrated that when the total distance between the first part 30141 and the second part 30142 is 300mm to 320mm, the angle of the second part 30142 is set to 15 degrees to 25 degrees, and the distance of the second part 30142 is set to 151mm to 153mm, the control of the final speed can be met. In order to control the moving speed of the material on the first part 30141, it is necessary to adjust the angle of the first part 30141. When the angle of the first part 30141 is less than 20 degrees, the speed will be slow, which is not conducive to the rapid passage of the material through the vibration plate 301. When the angle of the first part 30141 is greater than 40 degrees, the speed of the material will be too fast, which is not conducive to the first part 30141 controlling the speed of the material. Therefore, the angle range of the first part 30141 is 20 degrees to 40 degrees, and the distance of the first part 30141 can be 147mm to 169mm. For example, the distance of the second part 30142 is 151mm, and the distance of the first part 30141 can be 149mm to 169mm. Alternatively, the distance of the second part 30142 is 152 mm, and the distance of the first part 30141 is 148 mm to 168 mm, or the distance of the second part 30142 is 153 mm, and the distance of the first part 30141 is 147 mm to 167 mm. Of course, other combinations are also included, which are not listed here one by one. With such a configuration, when the first part 30141 is combined with vibration, the material can be accelerated to pass through the first part 30141 quickly. When the second part 30142 is combined with vibration, the material performs uniform linear motion or slowly accelerated motion, so that the speed of the material leaving the stable surface 3015 is within the range of 0.13 m / s to 0.25 m / s.

[0162] Preferably, the distance range for material movement between the first part 30141 and the second part 30142 is 300mm to 320mm, wherein the distance of the first part 30141 is 147mm to 169mm, and the distance of the second part 30142 is 151mm to 153mm. The angle between the first part 30141 and the horizontal plane is 30 degrees, and the angle between the second part 30142 and the horizontal plane is 15 degrees, which can ensure that the material passes through the vibration plate 301 quickly and can also well control the speed of the material when leaving the vibration plate 301.

[0163] In this embodiment, the outer diameter range of the vibration plate 301 is selected to be 1200mm to 1600mm. The outer diameter of the vibration plate 301 used in the experiment is 1460mm. The outer diameter of the vibration plate 301 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 to ensure the distance and angle matching relationship between the first part 30141 and the second part 30142.

[0164] Combine Figure 9 、 Figure 10 and Figure 11 As shown, in another implementation of this embodiment, the distance range for material movement between the first part 30141 and the second part 30142 is 430mm to 450mm, wherein the distance of the first part 30141 is 176mm to 198mm, and the distance of the second part 30142 is 252mm to 254mm. The angle between the first part 30141 and the horizontal plane is 35 degrees to 55 degrees, and the angle between the second part 30142 and the horizontal plane is 15 degrees to 25 degrees. The applicant has demonstrated through a large number of experiments that when the total distance between the first part 30141 and the second part 30142 is 430mm to 450mm, it can not only ensure that the material passes through the vibration plate 301 quickly, but also can well control the speed of the material when leaving the vibration plate 301.

[0165] Furthermore, the applicant discovered through comparative data that, although the movement distances in the above two embodiments are different, there is no proportional relationship between the first portions 30141 of the two embodiments, nor is there a proportional relationship between the second portions 30142 of the two embodiments. With the cooperation of the second material stop structure 402, the second portion 30142 has a greater impact on the final velocity. Therefore, the applicant has conducted extensive experimental demonstrations and demonstrated that, when the distance for material movement between the first portion 30141 and the second portion 30142 is 430 mm to 450 mm, setting the angle of the second portion 30142 to 15 to 25 degrees, and setting the distance of the second portion 30142 to 252 mm to 254 mm, can effectively control the final velocity. In order to control the moving speed of the material on the first part 30141, it is necessary to adjust the angle of the first part 30141. When the angle of the first part 30141 is less than 35 degrees, the speed will be slow, which is not conducive to the rapid passage of the material through the vibration plate 301. When the angle of the first part 30141 is greater than 55 degrees, the speed of the material will be too fast, which is not conducive to the first part 30141 controlling the speed of the material. Therefore, the angle range of the first part 30141 is 35 degrees to 55 degrees, and the distance of the first part 30141 can be 176mm to 198mm. For example, the distance of the second part 30142 is 252mm, and the distance of the first part 30141 can be 178mm to 198mm. Alternatively, the distance of the second part 30142 is 253 mm, and the distance of the first part 30141 is 177 mm to 197 mm, or the distance of the second part 30142 is 254 mm, and the distance of the first part 30141 is 176 mm to 196 mm. Of course, other combinations are also included, which are not listed here one by one. With such an arrangement, when the first part 30141 is combined with vibration, the material can be accelerated to pass through the first part 30141 quickly. When the second part 30142 is combined with vibration, the material performs uniform linear motion or slowly accelerated motion, so that the speed of the material leaving the stable surface 3015 is within the range of 0.13 m / s to 0.25 m / s.

[0166] Preferably, the distance range for material movement between the first part 30141 and the second part 30142 is 430 mm to 450 mm, wherein the distance of the first part 30141 is 176 mm to 198 mm, and the distance of the second part 30142 is 252 mm to 254 mm. The angle between the first part 30141 and the horizontal plane is 47 degrees, and the angle between the second part 30142 and the horizontal plane is 15 degrees to 25 degrees, which can not only ensure that the material passes through the vibration plate 301 quickly, but also can well control the speed of the material when leaving the vibration plate 301.

[0167] In this embodiment, the outer diameter range of the vibration plate 301 is selected to be 1500mm to 2000mm. The outer diameter of the vibration plate 301 used in the experiment is 1680mm. The outer diameter of the vibration plate 301 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 to ensure the distance and angle matching relationship between the first part 30141 and the second part 30142.

[0168] Combine Figure 6 、 Figure 7 and Figure 8 As shown, in this embodiment, the buffer surface 3013 is an inclined surface. For example, the angle between the buffer surface 3013 and the horizontal plane can be 15 degrees, or the angle of the buffer surface 3013 can be adjusted to other angles according to actual structural needs. The stabilizing surface 3015 is parallel to the horizontal plane. The stabilizing surface 3015 can guide the movement trajectory of the material. The material moves along the angle of the second part 30142 before entering the stabilizing surface 3015. In order to avoid the material from performing oblique throwing motion, the stabilizing surface 3015 can first guide the material to move in the horizontal direction. With the material movement speed range of 0.13m / s to 0.25m / s, the material can fall within the range of the detection device and the impurity removal device when leaving the stabilizing surface 3015.

[0169] Combine Figure 12 As shown, in this embodiment, an arc-shaped guide surface 30151 is provided at one end of the stabilizing surface 3015 away from the conveying surface 3014. The arc-shaped guide surface 30151 is used to guide the material to move in the height direction. After leaving the stabilizing surface 3015, the material can move along the arc-shaped guide surface 30151, thereby performing free falling movement in the height direction, so as to facilitate entering the range of action of the downstream detection device and the impurity removal device.

[0170] Combine Figure 8 and Figure 13 As shown, the shape of the vibration disk 301 is funnel-shaped, and the buffer surface 3013, the conveying surface 3014 and the stabilizing surface 3015 are arranged on the convex surface of the vibration disk 301. A plurality of strip reinforcement ribs 3018 are evenly arranged on the concave surface of the vibration disk 301. The strip reinforcement ribs 3018 extend from the center to the edge of the vibration disk 301. For example, ten strip reinforcement ribs 3018 can be arranged on the concave surface of the vibration disk 301, thereby improving the structural strength of the vibration disk 301 and improving the impact resistance of the vibration disk 301. Annular reinforcement ribs 3019 can be arranged at the edge of the concave surface of the vibration disk 301. For example, two annular reinforcement ribs 3019 are arranged on the concave surface of the vibration disk 301, respectively located near the center and near the edge, thereby further improving the structural strength of the vibration disk 301.

[0171] Combine Figure 13As shown, a plurality of mounting positions 30110 are provided on the edge of the concave surface of the vibration plate 301 , and the mounting positions 30110 can be used to connect with the bracket 6 of the ore dressing machine, for example, by connecting with the bracket 6 through a rubber spring.

[0172] Combine Figure 7 As shown, in one implementation of this embodiment, a first step surface 3016 is provided between the buffer surface 3013 and the conveying surface 3014. Since the vibration plate 301 needs to be installed with the vibrator 302 and cooperate with the distribution structure 10 of the ore dressing machine, the height size of the vibration plate 301 has requirements. The first step surface 3016 can play the role of connecting the buffer surface 3013 and the conveying surface 3014. For example, when the distance range for the movement of the ore raw materials by the first part 30141 and the second part 30142 on the vibration plate 301 is 300mm to 320mm, since the angle of the first part 30141 is 20 degrees to 40 degrees, the first step surface 3016 has a good transition connection effect. Among them, the distribution structure 10 is a vertical annular setting, that is, along Figure 14 Vertical orientation shown.

[0173] Combine Figure 10 As shown, when the distance range for the movement of the ore raw materials between the first part 30141 and the second part 30142 on the vibration plate 301 is 430 mm to 450 mm, the angle of the first part 30141 is 35 degrees to 55 degrees. There is no need to set the first step surface 3016 on the vibration plate 301, and the first part 30141 can be connected to the buffer surface 3013 by relying on the angle and distance.

[0174] Combine Figure 7 As shown, in one implementation of this embodiment, a second step surface 3017 is provided on the edge of the stabilizing surface 3015 away from the conveying surface 3014. Since the vibration disk 301 has a certain thickness, the second step surface 3017 can prevent the material from making secondary contact with the vibration disk 301 when leaving the arc-shaped guide surface 30151.

[0175] Combine Figure 14 、 Figure 15 and Figure 16 As shown, the sorting device includes a frame 5 and an exciter 302 .

[0176] The vibrating plate 301 is mounted on the frame 5 via the bracket 6. The exciter 302 is located at the center of the vibrating plate 301 and is used to provide an excitation force to the vibrating plate 301. The frame 5 is connected to the base of the fabric structure 10. The exciter 302 is mounted on the frame 5 via the bracket 6. The vibrating plate 301 is directly opposite the fabric structure 10 and is used to receive material from the fabric structure 10. For example, after passing through the fabric structure 10, the material will fall onto the vibrating plate 301. The excitation force of the exciter 302 drives the vibrating plate 301 to vibrate, causing the material to fall evenly along the annular surface of the vibrating plate 301, facilitating detection and impurity removal by the detection and impurity removal devices below.

[0177] Combine Figure 16 As shown, the lower surface of the vibration disk 301 is connected to the bracket 6 through a plurality of elastic support columns 7. Then, when the exciter 302 is working, the vibration disk 301 can vibrate relative to the bracket 6 through the elastic support columns 7 to avoid the excitation force being transmitted to the bracket 6. The elastic support columns 7 can be made of rubber or silicone material. The elastic support columns 7 have a hollow inner cavity. The two ends of the hollow inner cavity are respectively provided with a first fastener 8 and a second fastener 9. The first fastener 8 is connected to the vibration disk 301, and the second fastener 9 is connected to the bracket 6 to ensure that the vibration disk 301 can vibrate relative to the bracket 6. The first fastener 8 and the second fastener 9 have the same structure, both including 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 301 or the bracket 6.

[0178] The elastic support column 7 can also be replaced by a rubber spring.

[0179] The bracket 6 can be installed on the frame 5 through a support frame, which has multiple support arms connected to the edge of the bracket 6, thereby ensuring that there is a certain gap between the edge of the vibration plate 301 and the support frame, and the material can fall from the gap to facilitate subsequent detection and impurity removal.

[0180] A through hole 3011 is provided at the center of the vibration disk 301. The vibration disk 301 can serve as a receiving and conveying structure for materials. The vibration disk 301 can be made of manganese steel and can be controlled to vibrate by the exciter 302, thereby causing the material to move radially on the surface of the vibration disk 301.

[0181] Although the embodiments of the present invention have been described with reference to 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. Such modifications and variations are all within the scope defined by the appended claims.
