Magnetic separation equipment

Abstract

The present invention discloses a magnetic separation device, which drives a separation body to move back and forth on a support seat through a driving member. When a part of the separation body moves to the magnetic field zone, the mineral will flow from the output end of the ore feeding component to the feed port, and then enter this part of the separation body. The separation chamber is equipped with a magnetic medium, so the magnetic medium in the magnetic field zone will adsorb the magnetic mineral particles in the mineral under the action of the magnetic field force. When the separation body moves out of the magnetic field zone under the drive of the driving member, the magnetic medium in this part of the separation body is no longer affected by the magnetic field force. At the same time, this separation body is just in the unloading area. At this time, the flushing water flows from the output end of the unloading component to the feed port, and then enters the separation body. Since the separation body is continuously moved back and forth between the magnetic field zone and the unloading area under the drive of the driving member, the magnetic medium continuously performs adsorption and desorption operations on the magnetic mineral particles, greatly improving the magnetic separation efficiency of the magnetic separation equipment.

Description

Technical Field

[0001] The present invention relates to the technical field of mineral separation, in particular to a magnetic separation device. Background Art

[0002] Non-metallic minerals are widely used in traditional industries such as building materials, chemicals, energy, and light industry, as well as high-tech industries such as aerospace, electronics, communications, and new materials. In recent years, they have also gained widespread application in environmental protection and new energy. Non-metallic mineral materials generally require high purity, and impurity content often determines the quality grade of the product, especially iron content. Most non-metallic minerals found in nature contain harmful impurities such as iron, titanium, and manganese, which affect the product's whiteness and physical and chemical properties, limit its application areas, and reduce its market value.

[0003] Traditional magnetic separation equipment typically uses a vertical ring high-gradient magnetic separator. During the magnetic separation process, magnetic mineral particles are adsorbed on the magnetic medium on the separation ring due to the force of the magnetic field. When the magnetic medium is separated from the magnetic field as the separation ring rotates and enters the unloading area, the magnetic mineral particles lose the effect of the magnetic field force and, under the impact of the flushing water, detach from the magnetic medium and enter the concentrate hopper. However, because traditional magnetic separation equipment requires the separation ring to be rotated to a certain height to unload the magnetic mineral particles into the concentrate hopper, the magnetic separation efficiency of the magnetic separation equipment is seriously affected. At the same time, during the unloading process of traditional magnetic separation equipment, due to the rapid decay of the magnetic field strength and the uneven magnetic field, it is easy to cause a decrease in the magnetic separation rate. Summary of the Invention

[0004] Based on this, it is necessary to provide a magnetic separation device that can effectively improve the magnetic separation efficiency and is conducive to improving the magnetic separation rate.

[0005] The technical solution is as follows:

[0006] A magnetic separation device comprises: a support seat; a separation body, the separation body is slidably fitted on the support seat, the separation body is provided with a separation cavity and a feed port and a discharge port respectively connected to the separation cavity, the separation cavity is filled with magnetic medium; a magnetic system component, the magnetic system component is installed on the support seat, the magnetic system component comprises a first magnetic pole and a second magnetic pole, the working surface of the first magnetic pole and the working surface of the second magnetic pole are arranged correspondingly, and the first magnetic pole and the second magnetic pole are respectively located on both sides of the separation body, and a magnetic field area is formed between the first magnetic pole and the second magnetic pole; a feeding component, the feeding component The output end of the ore unloading assembly is arranged corresponding to the feed port, and the ore feeding assembly is used to transport minerals to the part of the sorting body located in the magnetic field zone; one or more ore unloading assemblies, the ore unloading assembly and the ore feeding assembly are respectively distributed along the moving direction of the sorting body on the support seat, and the output end of the ore unloading assembly is arranged corresponding to the feed port, and the ore unloading assembly is used to transport flushing water to the part of the sorting body located outside the magnetic field zone; and a driving member, the output end of the driving member is transmission-connected to the sorting body, and the sorting body can move back and forth on the support seat under the drive of the driving member.

[0007] The magnetic separation equipment described above uses a drive element to drive the separation body to reciprocate on the support base. When a portion of the separation body moves into the magnetic field zone, minerals flow from the output end of the feed assembly to the feed inlet, thereby entering this portion of the separation body. Because the separation chamber is filled with magnetic medium, the magnetic medium within the magnetic field zone attracts magnetic mineral particles within the minerals under the influence of the magnetic field force. Furthermore, because the working surfaces of the first and second magnetic poles are arranged in correspondence, the magnetic field strength within the magnetic field zone is evenly distributed, allowing magnetic media at different positions to effectively attract magnetic mineral particles, greatly improving the magnetic separation efficiency of magnetic mineral particles. When this portion of the separation body, driven by the drive element, moves out of the magnetic field zone, the magnetic medium within the separation body loses the magnetic field force and, therefore, no longer attracts magnetic mineral particles. At the same time, this portion of the separation body is located in the unloading area. At this time, flushing water flows from the output end of the unloading assembly to the feed inlet, thereby entering the separation body. In this way, the magnetic mineral particles originally adsorbed on the magnetic medium are separated from the magnetic medium by the impact of the flushing water, thereby effectively separating the magnetic mineral particles. As the separation body is driven by the driving element to continuously move back and forth between the magnetic field area and the ore unloading area, the magnetic medium continuously adsorbs and desorbs the magnetic mineral particles, thereby greatly improving the magnetic separation efficiency of the magnetic separation equipment.

[0008] In one embodiment, there are two ore unloading assemblies, and the two ore unloading assemblies are respectively located on both sides of the magnetic system assembly.

[0009] In one embodiment, the first magnetic pole includes a first magnetic yoke and a first excitation coil wound around the first magnetic yoke, and the second magnetic pole includes a second magnetic yoke and a second excitation coil wound around the second magnetic yoke.

[0031] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0032] Please refer to Figure 1 、 Figure 4 and Figure 8 In one embodiment, a magnetic separation device 100 includes: a support base 110, a separation body 120, a magnetic system assembly 130, an ore feeding assembly 140, one or more ore unloading assemblies 150, and a driving member 160. The separation body 120 is slidably fitted on the support base 110. The separation body 120 is provided with a separation cavity 121 and a feed port 122 and a discharge port 123 respectively connected to the separation cavity 121. The separation cavity 121 is filled with a magnetic medium 127. The magnetic system assembly 130 is mounted on the support base 110. The magnetic system assembly 130 includes a first magnetic pole 131 and a second magnetic pole 132. The working surface of the first magnetic pole 131 is arranged corresponding to the working surface of the second magnetic pole 132, and the first magnetic pole 131 and the second magnetic pole 132 are respectively located on both sides of the separation body 120, and a magnetic field region 134 is formed between the first magnetic pole 131 and the second magnetic pole 132. The output end of the feeding assembly 140 is arranged corresponding to the feed port 122. The feeding assembly 140 is used to transport minerals to the portion of the separation body 120 located within the magnetic field zone 134. The unloading assembly 150 and the feeding assembly 140 are respectively arranged along the direction of movement of the separation body 120 on the support base 110. The output end of the unloading assembly 150 is arranged corresponding to the feed port 122. The unloading assembly 150 is used to transport ore flushing water to the portion of the separation body 120 located outside the magnetic field zone 134. The output end of the driving member 160 is transmission-connected to the separation body 120. Driven by the driving member 160, the separation body 120 can move back and forth on the support base 110.

[0033] The above-mentioned magnetic separation equipment 100 drives the separation body 120 to move back and forth on the support base 110 through the driving member 160. When a part of the separation body 120 moves to the magnetic field area 134, the mineral will flow from the output end of the feeding assembly 140 to the feed port 122, and then enter this part of the separation body 120. Since the separation chamber 121 is equipped with a magnetic medium 127, the magnetic medium 127 in the magnetic field area 134 will absorb the magnetic mineral particles in the mineral under the action of the magnetic field force. At the same time, since the working surface of the first magnetic pole 131 and the working surface of the second magnetic pole 132 are arranged correspondingly, the magnetic field strength in the magnetic field area 134 is evenly distributed, so that the magnetic medium 127 in different positions can effectively absorb the magnetic mineral particles, greatly improving the magnetic separation rate of the magnetic mineral particles. When this portion of the separation body 120, driven by the driver 160, moves out of the magnetic field region 134, the magnetic medium 127 within the separation body 120 loses the effect of the magnetic field force and, therefore, no longer has an adsorption effect on the magnetic mineral particles. Simultaneously, this portion of the separation body 120 is located in the unloading area. At this time, the flushing water flows from the output end of the unloading assembly 150 to the feed port 122 and then into the separation body 120. Thus, the magnetic mineral particles originally adsorbed on the magnetic medium 127 are separated from the magnetic medium 127 by the impact of the flushing water, thereby effectively separating the magnetic mineral particles. Because the separation body 120 in this embodiment, driven by the driver 160, continuously moves back and forth between the magnetic field region 134 and the unloading area, the magnetic medium 127 continuously adsorbs and desorbs the magnetic mineral particles. Compared to conventional magnetic separation equipment 100, the magnetic separation equipment 100 of this embodiment is more compact and does not require the separation body 120 to be rotated to a certain height to disengage the magnetic mineral particles. This significantly improves the magnetic separation efficiency of the magnetic separation equipment 100. Furthermore, because the magnetic field force distribution within the magnetic field region 134 of this embodiment is relatively uniform, the separation body 120 is less affected by magnetic field intensity attenuation when moving within the magnetic field region 134. This effectively prevents magnetic mineral particles adsorbed on the magnetic medium 127 from being desorbed within the magnetic field region 134, thereby facilitating an improvement in the magnetic separation efficiency of the magnetic separation equipment 100. When there are two or more disengagement assemblies 150, some of the disengagement assemblies 150 are located on one side of the magnetic assembly 130, while others are located on the other side of the feed assembly 140. This allows the separation body 120 to effectively disengage magnetic mineral particles on both sides of the magnetic field region 134, thereby significantly improving the magnetic separation efficiency of the magnetic separation equipment 100. Furthermore, both the feeding assembly 140 and the unloading assembly 150 are mounted on the support base 110, or both the feeding assembly 140 and the unloading assembly 150 are mounted on the magnetic system assembly 130. The magnetic selectivity is the ratio of the amount of magnetic mineral particles adsorbed on the magnetic medium 127 to the total amount of magnetic mineral particles in the ore. The unloading area is the area outside the magnetic field area 134 to which the unloading assembly 150 can deliver the flushing water.Specifically in this embodiment, in order to ensure that the minerals enter the separation chamber 121 uniformly, a separator is provided in the feed assembly 140. In addition, the magnetic medium 127 is made of a sheet-shaped net, a rod-shaped, a steel wool-shaped or other shaped magnetic conductive material.

[0034] In another embodiment, please refer to Figure 9 There are at least two feed assemblies 140 and at least two magnetic system assemblies 130. The two or more feed assemblies 140 and the two or more magnetic system assemblies 130 are distributed along the direction of movement of the separation body 120 on the support base 110. This allows the separation body 120 to adsorb magnetic mineral particles within multiple magnetic field zones 134, thereby effectively increasing the adsorption capacity of the magnetic medium 127 and greatly improving the magnetic separation efficiency of the magnetic separation equipment 100.

[0035] Furthermore, there are two unloading assemblies 150. The two unloading assemblies 150 are respectively located on both sides of the magnetic system assembly 130. Figure 3 For example, when the sorting body 120 is driven by the driving member 160 to move to the left to the magnetic field area 134, the mineral enters the sorting chamber 121, and the magnetic medium 127 absorbs a large amount of magnetic mineral particles in the mineral under the action of the magnetic field force; when the sorting body 120 continues to move to the left, the sorting body 120 partially moves out of the magnetic field area 134, and the unloading assembly 150 transports a large amount of flushing water into the sorting chamber 121, so that the magnetic mineral particles are separated from the surface of the magnetic medium 127 under the impact of the flushing water; when the sorting body 120 moves to the left to the first preset position, the sorting body 120 will move to the right under the drive of the driving member 160. At this time, the magnetic medium 127 The magnetic mineral particles will be affected by the flushing water again, so that the magnetic mineral particles adsorbed on the magnetic medium 127 are completely separated from the magnetic medium 127, thereby greatly improving the recovery rate of the magnetic mineral particles; when the sorting body 120 continues to move to the right into the magnetic field area 134, the magnetic medium 127 adsorbs the magnetic mineral particles again under the action of the magnetic field force; when the sorting body 120 continues to move to the right out of the magnetic field area 134 under the drive of the driving member 160, the magnetic mineral particles adsorbed on the magnetic medium 127 are washed off by the flushing water again; when the sorting body 120 moves to the right to the second preset position, it moves to the left again under the drive of the driving member 160. In this way, by the sorting body 120 circulating back and forth on the support seat 110, the magnetic mineral particles in the mineral can be continuously and effectively adsorbed and desorbed, thereby further improving the magnetic separation efficiency of the magnetic separation equipment 100.

[0036] In one embodiment, please refer to Figure 4The first magnetic pole 131 includes a first magnetic yoke 1311 and a first excitation coil 1312 wound on the first magnetic yoke 1311. The second magnetic pole 132 includes a second magnetic yoke 1321 and a second excitation coil 1322 wound on the second magnetic yoke 1321. It can be seen that the magnetic system component 130 of this embodiment is an electromagnetic component. During the magnetic separation process, by energizing the first excitation coil 1312 and the second excitation coil 1322 respectively, a more uniform horizontal magnetic field is formed between the first magnetic pole 131 and the second magnetic pole 132, so that the magnetic mineral particles are more fully adsorbed on the magnetic medium 127, thereby further improving the magnetic separation rate of the magnetic separation equipment 100.

[0037] In another embodiment, the first magnetic pole 131 and the second magnetic pole 132 can be permanent magnets. The two permanent magnets are respectively located on both sides of the separation body 120, and the working surfaces of the two permanent magnets are arranged correspondingly.

[0038] Furthermore, the magnetic system assembly 130 further includes an upper magnetic pole 133. The two ends of the upper magnetic pole 133 are connected to the first magnetic pole 131 and the second magnetic pole 132 respectively. In this way, the magnetic field strength between the first magnetic pole 131 and the second magnetic pole 132 is greatly improved, which is more conducive to improving the adsorption capacity of the magnetic medium 127 for magnetic mineral particles, thereby making the magnetic separation device 100 have a higher magnetic separation rate. For details in this embodiment, please refer to Figure 4 A through hole 1331 is provided on the upper magnetic pole 133 , and the through hole 1331 is arranged corresponding to the output end of the feeding assembly 140 . In this way, when the feeding assembly 140 feeds the sorting body 120 , the mineral first flows through the through hole 1331 and then flows into the sorting cavity 121 .

[0039] For further information, please refer to Figure 6 In this embodiment, there are more than two magnetic system components 130. The two or more magnetic system components 130 are arranged in parallel, so that the magnetic separation efficiency of the magnetic separation device 100 is further improved.

[0040] In one embodiment, please refer to Figure 3 、 Figure 6 、 Figure 7 and Figure 8The magnetic separation equipment 100 also includes a first collecting element 170 and one or more second collecting elements 180. Both the first collecting element 170 and the second collecting element 180 are mounted on the support base 110, with the first collecting element 170 corresponding to the feeding assembly 140. The second collecting element 180 is corresponding to the unloading assembly 150. The first collecting element 170 is used to collect the minerals after magnetic separation. The second collecting element 180 is used to collect the magnetic mineral particles washed away. As can be seen, the adsorbed minerals enter the first collecting element 170 through the discharge port 123 of the separation body 120, while the washed magnetic mineral particles enter the second collecting element 180 through the discharge port 123 of the separation body 120. This allows the magnetic mineral particles in the minerals to be effectively separated and collected. Specifically, in this embodiment, there are two unloading assemblies 150 and two second collecting elements 180. The two unloading assemblies 150 are located on either side of the feeding assembly 140, and the two second collecting elements 180 are located on either side of the first collecting element 170. This facilitates the effective collection of magnetic mineral particles washed down from both sides of the magnetic field region 134. In addition, the first collecting member 170 and the second collecting member 180 are funnel-shaped structures, which facilitates the first collecting member 170 or the second collecting member 180 to better collect tailings or magnetic mineral particles.

[0041] In one embodiment, please refer to Figure 1 The magnetic separation device 100 further includes a telescopic mechanism 190. One end of the telescopic mechanism 190 is connected to the separation body 120, and the other end of the telescopic mechanism 190 is connected to the output end of the driving member 160. In this way, the separation body 120 can stably reciprocate on the support base 110.

[0042] Optionally, the telescopic mechanism 190 is an electric push rod, a rack and pinion mechanism, a ball screw, a crank slider mechanism or other telescopic mechanisms.

[0043] For further information, please refer to Figure 1 The separation body 120 is provided with a roller 124. The support base 110 is provided with a guide rail 111. The roller 124 and the guide rail 111 are in rolling engagement. Thus, the rolling engagement between the roller 124 and the guide rail 111 allows the separation body 120 to move more smoothly and conveniently on the support base 110, thereby facilitating more stable operation of the magnetic separation device 100.

[0044] For further information, please refer to Figure 8 The magnetic separation device 100 further includes a support frame 126. The support frame 126 is mounted on the separation body 120. The roller 124 is mounted on the support frame 126. The support frame 126 ensures a more stable mounting of the roller 124 on the separation body 120 and also enhances the rigidity of the separation body 120, thereby improving the structural stability of the magnetic separation device 100.

[0045] In one embodiment, please refer to Figure 4 and Figure 5 The separation body 120 is also provided with a first guide portion 125. A second guide portion 112 is also provided on the support base 110 or the magnetic assembly 130. The first guide portion 125 cooperates with the second guide portion 112 to guide the separation body 120. This ensures that the separation body 120 moves along a predetermined trajectory, preventing the separation body 120 from shifting during reciprocating movement on the support base 110, which could cause minerals or flushing water to spill outside the separation body 120.

[0046] Optionally, the first guide portion 125 is a guide bar, and the second guide portion 112 is a guide groove. For specific structures, please refer to Figure 4 ; Or the first guide portion 125 is a guide groove, and the second guide portion 112 is a guide bar; or the first guide portion 125 can also be a guide rail, and the second guide portion 112 can also be a guide wheel; or the first guide portion 125 is a guide wheel, and the second guide portion 112 is a guide rail structure, the specific structure can refer to Figure 5 In this way, the cooperation between the guide wheel and the guide rail structure not only enables the sorting body 120 to move stably on the support base 110, but also makes the movement of the sorting body 120 smoother and more convenient.

[0047] In one embodiment, a limit switch is provided on the support base 110. The limit switch cooperates with the limiting position of the sorting body 120. In this way, a limit signal is generated to the driving member 160 through the limit switch, and then the driving member 160 causes the sorting body 120 to accurately pause at a preset position and causes the sorting body 120 to turn and move, thereby enabling the limit of the magnetic separation equipment 100 to be accurately controlled, which is conducive to a more stable operation of the magnetic separation operation of the magnetic separation equipment 100. Specifically, in this embodiment, there are two limit switches. The two limit switches are located on the other two sides of the sorting body 120, so that the sorting body 120 moves back and forth between the two limit switches. At the same time, when the limit switch cooperates with the limiting position of the sorting body 120, one side of the sorting body 120 just enters the magnetic field area 134, thus effectively preventing the sorting body 120 from completely moving out of the magnetic field area 134 as a whole, thereby causing the minerals in the feeding assembly 140 to be directly discharged without undergoing magnetic separation. At the same time, this design can effectively prevent a portion of the separation cavity 121 from ever entering the magnetic field region 134 , thereby causing a portion of the separation body 120 to remain unused. This is more conducive to improving the magnetic separation efficiency of the magnetic separation equipment 100 .

[0048] In one embodiment, please refer to Figure 2 and Figure 8The unloading assembly 150 includes a buffer body 151 and a connecting pipe 152 and a plurality of water pipes 153 respectively installed on the buffer body 151. A buffer cavity 1511 is provided on the buffer body 151. The connecting pipe 152 and the water pipe 153 are respectively connected to the buffer cavity 1511. It can be seen that the flushing water flows into the buffer cavity 1511 from the connecting pipe 152, and then is transported to the sorting cavity 121 through the plurality of water pipes 153. In this way, the magnetic medium 127 in the sorting cavity 121 can be flushed by the flushing water, effectively preventing the local magnetic medium 127 from being unable to be affected by the flushing water due to its position in the blind area.

[0049] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.

When there are more than two unloading assemblies, some of the unloading assemblies are located on one side of the magnetic assembly, and the other part of the unloading assemblies are located on the other side of the magnetic assembly; The separation body is further provided with a first guide portion, and the support seat or the magnetic system assembly is further provided with a second guide portion, and the first guide portion cooperates with the second guide portion to guide and cooperate with each other so that the separation body moves along a predetermined trajectory; When the separation body moves to the left to the magnetic field area under the drive of the driving part, the mineral enters the separation chamber, and the magnetic medium absorbs a large amount of magnetic mineral particles in the mineral under the action of the magnetic field force; when the separation body continues to move to the left, the separation body part moves out of the magnetic field area, and the unloading component transports a large amount of flushing water into the separation chamber, so that the magnetic mineral particles are separated from the surface of the magnetic medium under the impact of the flushing water; when the separation body moves to the left to the first preset position, the separation body will move to the right under the drive of the driving part. At this time, the magnetic mineral particles will be affected by the flushing water again, causing the adsorption The magnetic mineral particles on the magnetic medium are completely separated from the magnetic medium; when the sorting body continues to move to the right into the magnetic field area, the magnetic medium again adsorbs the magnetic mineral particles under the action of the magnetic field force; when the sorting body continues to move to the right out of the magnetic field area under the drive of the driving member, the magnetic mineral particles adsorbed on the magnetic medium are again washed off by the flushing water; when the sorting body moves to the right to the second preset position, it moves to the left again under the drive of the driving member. In this way, the magnetic mineral particles in the mineral can be continuously and effectively adsorbed and desorbed by the sorting body moving back and forth on the support seat.
