Description

Technical Field

[0001] The utility model relates to the technical field of mining engineering, in particular to a magnetic diversion structure and a dry separator. Background Art

[0002] With the increasing amount of iron ore mining, the amount of lean magnetite ore and ultra-lean magnetite ore selected is increasing. In order to improve the grinding grade of magnetite ore and reduce the grinding cost, a pre-dry separation process is usually adopted to discard waste before the magnetite ore is ground, so as to achieve the purpose of improving the grade of the ore entering the mill and reducing the production cost of mineral processing.

[0003] The currently commonly used dry separation process is dry separation of finely crushed ore, that is, the undersize finely crushed ore from the closed-circuit crushing and screening operation is dry-separated to obtain dry-separation concentrate and dry-separation waste rock. The dry-separation concentrate is used as the ore entering the mill, and the dry-separation waste rock is discarded. The dry separator mainly includes a magnetic pulley or a CT magnetic drum or a CTDG magnetic drum or a CTX magnetic drum. The magnetic pulley has a 360° magnetic system, is fixed to the outer cylinder and rotates synchronously, without magnetic flipping, and has serious intermingling, and is no longer used in the field of magnetite ore separation; the magnetic systems of the CT magnetic drum or the CTDG magnetic drum are fixed, the magnetic system wrap angle is about 170°, the magnetic field strength on the drum surface is 0.2 - 0.6T, and the belt conveying speed is 1.2 - 2.5m / s. During dry separation, the number of magnetic flips of magnetic particles is small, resulting in waste rock being intermingled in the dry-separation concentrate and magnetite ore being intermingled in the dry-separation waste rock, and the dry-separation effect is poor; the CTX magnetic drum has a magnetic system wrap angle of 360°, the magnetic field strength on the surface of the outer cylinder is ≥0.4T, the sorting belt speed is ≥2.5m / s, and the magnetic system rotation speed is ≥80r / min. Its outer cylinder and magnetic system rotate in opposite directions to form a rotating magnetic field. When magnetic ore particles pass through, rapid magnetic flipping and magnetic agitation occur in the magnetic pole alternating area. Under the combined action of magnetic force, centrifugal force and gravity, non-(weak) magnetic waste rock particles intermingled between magnetic ore particles will move outward under the action of magnetic agitation and centrifugal force, while magnetic ore particles intermingled between non-(weak) magnetic waste rock particles will move inward under the action of a strong magnetic force, so as to realize the efficient separation of magnetic ore particles and non-(weak) magnetic waste rock particles, and can fully discard non-(weak) magnetic waste rock particles intermingled between magnetic ore particles. The obtained dry-separation concentrate has a high grade, and the dry-separation waste rock has a low grade, that is, the qualified dry-separation waste discard rate is high, and the separation effect is good.

[0004] The CTX magnetic drum can discard a large amount of qualified waste rock, reduce the grinding and separation costs, thus greatly reducing the production cost of mineral processing, reducing the amount of fine tailings entering the tailings pond, increasing the service life of the tailings pond, and having a high utilization value for coarse waste rock, so as to achieve cost reduction and efficiency increase in the concentrator.

[0005] Whether it is a conventional CT magnetic drum or a CTDG magnetic drum, or a new type of CTX magnetic drum, the width of the sorting interval is the same as the axial length of the magnetic system of the magnetic drum. Generally, a leveling device is used to level the incoming ore. Therefore, some ore will splash to both sides of the belt after hitting the leveling device, and even some ore will cross the width range of the sorting interval and pass outside the magnetic system of the magnetic drum without being subjected to dry magnetic separation, resulting in the loss of magnetite. To avoid the above phenomena, generally, a diversion plate bottom plate made of carbon steel plate is used, and a sealing plate made of waste rubber belt and directly contacting the surface of the belt transporting ore is clamped on the diversion plate bottom plate to jointly form a diversion plate to prevent the ore from splashing outside the sorting area and ensure the recovery rate of magnetic iron. With the above diversion plate, in order to reduce the friction between the sealing plate made of waste rubber belt and the surface of the belt transporting ore, a polyurethane sealing plate is also used instead of the sealing plate made of waste rubber belt. However, in order to strengthen the sealing and diversion, the above diversion plates must directly contact the surface of the belt transporting ore, so the surface of the belt transporting ore is worn. In special cases, when the above diversion plate is relatively long, or / and the speed of the belt transporting ore is relatively fast, ore particles will be clamped between the diversion plate and the transport belt, exacerbating the wear of the rubber belt transporting ore. Summary of the Invention

[0006] The present invention provides a magnetic diversion structure and a dry separator to solve the defect of serious wear between the diversion plate and the transport belt in the prior art, and to reduce the wear of the magnetic diversion component on the surface of the transport belt and improve the service life of the transport belt and the magnetic diversion structure.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific situations.

[0036] The present utility model provides a magnetic flow guiding structure and a dry separator.

[0037] In the embodiments of the present utility model, as Figures 1 to 4As shown, a magnetic diversion structure 10 is provided, which includes a magnetic diversion assembly 100. The magnetic diversion assembly 100 is disposed above the conveyor belt 20 and extends along the driving direction of the conveyor belt 20. The magnetic diversion assembly 100 is spaced from the upper surface of the conveyor belt 20. The magnetic diversion assembly 100 has a magnetic surface 111a facing the conveyor belt 20, and at least part of the magnetic surface 111a is disposed opposite to the conveyor belt 20.

[0038] The magnetic diversion assembly 100 is used to isolate and block the transported materials on the conveyor belt 20, form a relatively separated transportation environment, guide the materials to a predetermined position or path, and prevent dust from escaping or materials from splashing and polluting the environment. At the same time, the magnetic diversion assembly 100 in this application can generate a certain magnetic field.

[0039] The magnetic diversion assembly 100 is spaced from the upper surface of the conveyor belt 20. The spaced arrangement avoids direct contact between the magnetic diversion assembly 100 and the conveyor belt 20, thereby reducing the wear caused by sliding friction. In addition, the space also allows the formation of a magnetite separation layer, further reducing wear and improving the working environment.

[0040] The magnetic diversion assembly 100 has a magnetic surface 111a facing the conveyor belt 20. The magnetic surface 111a is the key part for generating the magnetic field. It faces the conveyor belt 20, enabling the conveyor belt 20 to effectively adsorb magnetic materials during the transportation of magnetic materials, form a magnetite separation layer between the magnetic surface 111a and the upper surface, dynamically fill the gap between the magnetic surface 111a and the conveyor belt 20, achieve effective blocking of the transported materials, prevent the particles of the transported materials from splashing, and reduce the escape of dust.

[0041] At least part of the magnetic surface 111a is disposed opposite to the conveyor belt 20, ensuring that a stable magnetite separation layer can be formed between the magnetic surface 111a and the conveyor belt 20.

[0042] In this application, a magnetic diversion assembly 100 is provided above the conveyor belt 20. The magnetic diversion assembly 100 has a magnetic surface 111a facing the conveyor belt 20. When the transported material of the belt conveyor is magnetite ore, fine-grained magnetite ore is adsorbed on the magnetic surface 111a under the action of magnetic field force, and a magnetite separation layer will be formed between the upper surface of the conveyor belt 20 and the magnetic surface 111a. Alternatively, a small amount of magnetite concentrate powder can be added in advance to make it adsorb on the magnetic surface 111a to form a magnetite separation layer. Due to the good dynamic separation and diversion effect of the magnetite separation layer, it prevents the particles of the transported material from splashing and reduces the escape of dust. At the same time, the friction generated between the magnetite separation layer and the upper surface of the conveyor belt 20 is dynamic friction (such as rolling friction), significantly reducing the wear of the diversion structure on the surface of the conveyor belt 20 and improving the service life of the conveyor belt 20. When the transported material of the belt conveyor is magnetite ore, the material of the magnetite separation layer can be self-generated, reducing the loss of the material for making the deflector 110 and lowering the operating cost.

[0043] Referring to Figure 2 and Figure 3 , according to a magnetic diversion structure 10 provided by the present utility model, the magnetic diversion assembly 100 includes at least two deflectors 110, and the deflectors 110 are respectively arranged on both sides of the conveyor belt 20 in the extending direction.

[0044] It can be understood that the deflectors 110 are respectively installed on both sides of the conveyor belt 20 to form a channel or boundary for guiding the flow of materials. Through the physical blocking and guiding effects of the deflectors 110, the materials can maintain a certain flow direction and distribution state on the conveyor belt 20. This helps to prevent the materials from scattering or splashing during transportation and ensures that the materials can be stably transported.

[0045] According to a magnetic diversion structure 10 provided by the present utility model, the distance between the deflectors 110 on both sides of the conveyor belt 20 in the extending direction is less than or equal to the axial length of the magnetic system of the magnetic drum of the dry separator.

[0046] It can be understood that the distance between the deflectors 110 on both sides of the conveyor belt 20 in the extending direction is set to be less than or equal to the axial length of the magnetic system of the magnetic drum of the dry separator. The magnetic field generated by the magnetic drum during operation can fully cover and affect the area enclosed between the deflector 110 and the conveyor belt 20, ensuring that all the materials transported by the conveyor belt 20 can pass through magnetic separation.

[0047] According to a magnetic diversion structure 10 provided by the present utility model, the distance between the magnetic surface 111a and the upper surface of the conveyor belt 20 is greater than or equal to 1 mm and less than or equal to 50 mm.

[0048] It can be understood that the spacing between the magnetic surface 111a and the upper surface of the conveyor belt 20 can be set according to the particle size of magnetite particles on the conveyor belt 20. However, if the spacing between the magnetic surface 111a and the upper surface of the conveyor belt 20 is too large or too small, it will affect the formation of the magnetite separation layer. In this embodiment, the spacing between the magnetic surface 111a and the upper surface of the conveyor belt 20 is greater than or equal to 1 mm and less than or equal to 50 mm, which can contribute to the rapid formation of the magnetite separation layer and can be set according to the specific particle size of magnetite, and no special limitation is made here.

[0049] Referring to Figure 3 and Figure 4 , according to a magnetic diversion structure 10 provided by the present utility model, the diversion plate 110 includes a housing 111 and a plurality of magnetic blocks 120. An accommodation cavity 111b is formed inside the housing 111, a magnetic surface 111a is formed on the bottom end surface of the housing 111, and the plurality of magnetic blocks 120 are stacked in the accommodation cavity 111b along a direction away from the magnetic surface 111a.

[0050] It can be understood that the housing 111 serves as the main structure of the entire diversion plate 110. The housing 111 not only provides mechanical support and protection, but also defines the position and shape of the magnetic surface 111a. The accommodation cavity 111b formed inside the housing 111 is used to install and fix the magnetic blocks 120. The magnetic surface 111a is formed on the bottom end surface of the housing 111. Through the magnetic field action of the internal magnetic blocks 120, the magnetic surface 111a generates an attractive force on magnetic substances to form a magnetite separation layer. The plurality of magnetic blocks 120 are stacked in the accommodation cavity 111b along a direction away from the magnetic surface 111a. This arrangement can flexibly adjust the intensity and distribution of the magnetic field to meet different processing requirements.

[0051] Optionally, the magnetic block 120 is preferably a strontium ferrite magnetic block. If it is desired to obtain a stronger magnetism of the magnetic surface 111a or a thinner magnetic component is required, the magnetic block 120 can be a neodymium iron boron magnetic block, and no special limitation is made here.

[0052] Referring to Figure 5 and Figure 6 , according to a magnetic diversion structure 10 provided by the present utility model, the magnetic diversion structure 10 further includes a suspension assembly 200. The suspension assembly 200 includes a cross beam 210 and suspension members 220 provided at the ends of the cross beam 210. The magnetic diversion assembly 100 is connected to the cross beam 210, and the cross beam 210 is connected to the top plate of the hood of the dry separator through the suspension members 220.

[0053] It is understandable that the magnetic diversion assembly 100 is connected to the cross beam 210 through an appropriate connection method (such as bolt connection, welding or other fastening methods), ensuring that the magnetic diversion assembly 100 can maintain a stable position and posture during operation, while being convenient for maintenance and replacement. The cross beam 210 is connected to the top plate of the hood of the dry separation machine through the suspension member 220 at its end. The suspension member 220 can have an adjustable design to adjust the height and position of the cross beam 210 according to actual needs. The connection between the suspension member 220 and the top plate of the hood usually uses bolt connection or other reliable fasteners to ensure the firmness and safety of the connection.

[0054] Referring to Figure 2 and Figure 4 According to a magnetic diversion structure 10 provided by the present utility model, the magnetic diversion assembly 100 further includes a first connecting member 130, and the magnetic diversion assembly 100 is connected to the cross beam 210 through the first connecting member 130.

[0055] It is understandable that the main function of the first connecting member 130 is to firmly connect the magnetic diversion assembly 100 to the cross beam 210. The first connecting member 130 provides the necessary mechanical connection points, and the first connecting member 130 ensures the stable position of the magnetic diversion assembly 100 on the dry separation machine.

[0056] Referring to Figure 1 and Figure 7 According to a magnetic diversion structure 10 provided by the present utility model, the magnetic diversion structure 10 further includes an adjusting assembly 300. The adjusting assembly 300 is arranged at one end of the suspension member 220 away from the magnetic diversion assembly 100, and the adjusting assembly 300 is used to adjust the distance between the magnetic surface 111a and the upper surface of the conveyor belt 20.

[0057] It is understandable that the setting of the adjusting assembly 300 allows the user to adjust the distance between the magnetic surface 111a and the upper surface of the dry separation machine as needed. By adjusting the distance, it is ensured that the magnetic diversion structure 10 can form a reasonable separation layer to prevent coarse-grained magnetic substances from being clamped between the magnetic surface 111a and the upper surface of the conveyor belt 20 and wearing the upper surface of the conveyor belt 20. The adjustment of the distance can ensure that the magnetic diversion structure 10 can achieve the best effect when processing different materials.

[0058] According to a magnetic diversion structure 10 provided by the present utility model, the adjusting assembly 300 includes a gasket 310, an elastic member 320 and a nut 330. The elastic member 320 is sleeved on the outside of the suspension member 220. A thread is provided at the end of the suspension member 220 away from the cross beam 210, and the nut 330 is in threaded cooperation with the suspension member 220. The gasket 310 abuts between the elastic member 320 and the nut 330.

[0059] It can be understood that the gasket 310 is located above the elastic member 320. Its function is to provide a pressing force for the elastic member 320 when the nut 330 is tightened, which is used to automatically fine-tune the distance between the magnetic surface 111a and the upper surface of the conveyor belt 20, discharge the coarse-grained magnetic substances held between the magnetic surface 111a and the upper surface of the conveyor belt 20, and prevent the coarse-grained magnetic substances from wearing the upper surface of the conveyor belt 20. The material and thickness of the gasket 310 can be selected according to needs to meet the above adjustment requirements. The elastic member 320 is sleeved on the outside of the suspension member 220 and can deform when the nut 330 is adjusted, thereby changing the distance between the magnetic surface 111a and the upper surface of the dry separator, and also automatically fine-tuning the distance between the magnetic surface 111a and the upper surface of the dry separator when discharging the coarse-grained magnetic substances held between the magnetic surface 111a and the upper surface of the conveyor belt 20. Common elastic members 320 include springs, rubber sleeves, etc., and the specific selection depends on the required adjustment range and elastic requirements. The nut 330 is in threaded fit with the end of the suspension member 220 far from the cross beam 210. By rotating the nut 330, the lifting and fixing of the suspension member 220 can be realized, so as to realize the precise adjustment of the distance between the magnetic surface 111a and the upper surface of the dry separator.

[0060] When it is necessary to adjust the distance between the magnetic surface 111a and the upper surface of the dry separator, it can be realized by rotating the nut 330. Rotating the nut 330 will cause it to move along the thread of the suspension member 220, thereby changing the degree of compression of the elastic member 320. When the elastic member 320 is compressed, it will deform, and this deformation will be converted into the lifting movement of the suspension member 220, thereby changing the position of the magnetic surface 111a.

[0061] The present utility model also proposes a dry separator, which includes a magnetic diversion structure 10. The specific structure of the magnetic diversion structure 10 refers to the above-mentioned embodiments. Since this dry separator adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated one by one here.

Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.
