Description

Technical Field

[0001] This invention relates to the field of magnetic separation technology, and in particular to a method for controlling a multi-stage magnetic separation process. Background Technology

[0002] In the copper smelting industry, copper smelting slag flotation tailings usually contain a certain amount of valuable metals such as iron and copper, as well as magnetic minerals. Effective magnetic separation of these tailings can realize resource recycling and reduce the environmental pressure caused by tailings discharge.

[0003] However, the existing magnetic separation process for copper smelting slag flotation tailings has many problems. Process parameters such as magnetic field strength, pulp concentration, and pulp particle size are difficult to control precisely, leading to unstable separation results and low recovery rates of valuable metals and low concentrate grades. Specifically:

[0004] 1. Insufficient separation of magnetic materials: In existing multi-stage magnetic separation processes, the tailings produced by the previous stage of magnetic separation often have large feed particles. Due to the large size of the particles, the magnetic materials inside are difficult to be fully exposed, making it difficult for subsequent magnetic separators to effectively capture and separate them. For example, when processing iron ore magnetic separation, the magnetic iron minerals wrapped in the larger particles of tailings cannot be completely selected by the subsequent magnetic separators, resulting in a reduced recovery rate of magnetic products. At the same time, a lot of recyclable magnetic materials remain in the tailings, causing a waste of resources.

[0005] 2. Impact on magnetic separation accuracy: The presence of large-particle tailings disrupts the uniformity of materials during the magnetic separation process. Under the influence of the magnetic field, the magnetic field distribution around the large-particle tailings becomes distorted, interfering with the normal magnetic separation path of the small-particle materials. This reduces the accuracy of the magnetic separator in identifying and separating magnetic particles, resulting in an increase in the impurity content of the final magnetic product. The product quality cannot meet the needs of high-end industrial applications, such as electronic materials and high-end magnetic materials, where the purity requirements for magnetic products are extremely high. The problem of large-particle tailings severely restricts the improvement of product quality. Summary of the Invention

[0006] In view of the existence of the above-mentioned prior art, the present invention is proposed.

[0007] Therefore, the purpose of this invention is to provide a method for controlling a multi-stage magnetic separation process.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A mounting component includes a support frame, on one side of which a first magnetic separator, a second magnetic separator, and a third magnetic separator are provided. Mounting frames are provided on one side of each of the first, second, and third magnetic separators. Magnetic separator cylinders are provided inside each of the first, second, and third magnetic separators. A feeding box is provided on one side of the first magnetic separator, located on one side of the mounting frame. A connecting pipe is provided between the first, second, and third magnetic separators, and a conveyor belt is provided inside the connecting pipe. A connecting component includes a feeding assembly for feeding tail material into the feeding box, a guiding assembly for guiding tail material flow on one side of the feeding box, a rinsing assembly for rinsing tail material into the feeding box, a pneumatic assembly for cleaning the conveyor belt on one side of the support frame, a limiting assembly for limiting the pneumatic assembly within the connecting pipe, and a flow guiding assembly for guiding tail material flow on one side of the connecting pipe.

[0009] The method of this magnetic separator includes the following steps:

[0010] S1. The tailings are fed into the feeding box and then flowed into the first magnetic separator;

[0011] S2. The tail material is subjected to contact crushing treatment by the feeding component, which can perform preliminary crushing and refining treatment of the tail material.

[0012] S3. While being guided by the guide component, the material is also washed by the flushing component. The flushing process can be used to separate the tail material and promote its flow, which helps to further feed the raw material and perform magnetic separation.

[0013] S4. After the tailings enter the first magnetic separator, they are subjected to magnetic separation in the magnetic separator drum, and the target raw materials and impurities can be initially separated. Then, they pass through the connecting pipe and are separated from the impurities by the conveyor belt. The conveyor rollers on the conveyor belt are equipped with magnetic separation structures inside, which can be used for raw material conveying and initial separation.

[0014] S5. When the tail material in the connecting pipe is conveyed by the conveyor belt, some tail material will remain on the conveyor belt. At this time, the pneumatic component is used to clean and wash the residue on the conveyor belt to avoid raw material residue. Then, it is circulated through the guide component and conveyed to the second magnetic separator for the next magnetic separation process.

[0015] S6. After being processed by the first magnetic separator, it is transported through the connecting pipe to the second and third magnetic separators for gradual magnetic separation.

[0016] In a preferred embodiment of the multi-stage magnetic separation process control method of the present invention, the feeding assembly includes an extrusion shaft disposed within a feeding box, an extrusion roller disposed on the side wall of the extrusion shaft, a drive gear fixedly connected to both ends of the extrusion shaft, a propulsion tooth plate disposed between the two drive gears, the drive gear engaging with the propulsion tooth plate, a fixing frame fixedly connected to both sides of the feeding box, a limit groove formed on one side of the fixing frame, the propulsion tooth plate slidably connected within the limit groove, a motor fixedly connected to one side of the feeding box, a drive gear fixedly connected to the output shaft of the motor, the drive gear meshing with the drive gear on one side.

[0019] In a preferred embodiment of the multi-stage magnetic separation process control method of the present invention, the pneumatic component passes through the push tube of the sliding connection fixed frame, the push tube is slidably connected to the guide rod, a propulsion cylinder is fixedly connected to one side of the mounting frame, an air inlet piston of the propulsion cylinder is fixedly connected to one end of the push tube, an air pipe is fixedly connected to the air outlet of the propulsion cylinder, a connecting cylinder is connected to one end of the air pipe, a movable frame is fixedly connected to the telescopic end of the connecting cylinder, cleaning rollers are provided on both sides of the conveyor belt, the cleaning rollers are rotatably connected inside the connecting tube, two symmetrically arranged connecting gears are provided on the side wall of the cleaning rollers, and movable toothed plates are fixedly connected to both sides of the movable frame, the movable toothed plates meshing with the connecting gears.

[0020] As a preferred embodiment of the multi-stage magnetic separation process control method of the present invention, the limiting component includes two symmetrically arranged limiting shafts rotatably connected to the inner wall of the connecting pipe, and a limiting groove is opened on one side of the moving frame, with the limiting shafts passing through the limiting groove.

[0021] As a preferred embodiment of the multi-stage magnetic separation process control method of the present invention, the flow guiding component includes an inclined groove disposed on one side of the connecting pipe, the flow guiding groove being provided on one side of the connecting pipe, and the inclined groove communicating with the flow guiding groove.

[0022] The beneficial effects of the multi-stage magnetic separation process control method of the present invention are as follows:

[0023] 1. This invention incorporates a feeding box, extrusion rollers, extrusion shaft, shaking frame, and swing frame. By installing a targeted crushing device before the tailings enter the subsequent magnetic separation stage, large tailings are crushed to a suitable particle size. This not only fully exposes the magnetic materials in the tailings, facilitating more efficient capture and separation by the subsequent magnetic separator, significantly improving the recovery rate of magnetic products and reducing resource waste, but also avoids interference from large tailings on magnetic separation accuracy, improving product purity and meeting the stringent quality requirements of high-end industrial applications for magnetic products. Simultaneously, the tailings conveying process is optimized by employing conveying equipment more suitable for large particles and rationally planning the conveying route, reducing bends and drops, effectively preventing blockages, jamming, collisions, and accumulation of tailings during conveying. This ensures the continuity and efficiency of the conveying process, making the entire magnetic separation process smoother, improving production efficiency, and reducing equipment failure rates and maintenance costs.

[0024] 2. This invention incorporates structures such as a cleaning roller, a moving toothed plate, a moving frame, an inclined trough, a guide trough, and a propulsion cylinder. During the tail material conveying process, this process control method fully considers the cleanliness of the conveyor belt. By installing an automatic cleaning device on the conveyor belt, materials adhering to the conveyor belt are removed in a timely manner, preventing material residue from causing wear on the conveyor belt, effectively extending the service life of the conveyor belt, and reducing the cost of replacing the conveyor belt.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0039] Example 1

[0040] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a multi-stage magnetic separation process control method, which can achieve the effect of tailings crushing treatment. Its installation component 100 includes a support frame 101. A first magnetic separator 102, a second magnetic separator 103 and a third magnetic separator 104 are provided on one side of the support frame 101. A mounting frame 107 is provided on one side of each of the first magnetic separator 102, the second magnetic separator 103 and the third magnetic separator 104. A magnetic separation cylinder 108 is provided inside each of the first magnetic separator 102, the second magnetic separator 103 and the third magnetic separator 104. A feeding box 105 is provided on one side of the first magnetic separator 102 and is located on one side of the mounting frame 107. A connecting pipe 106 is provided between each of the first magnetic separator 102, the second magnetic separator 103 and the third magnetic separator 104. A conveyor belt 109 is provided inside the connecting pipe 106.

[0041] The connecting component 110 includes a feeding assembly 120 disposed in the feeding box 105 for feeding tail material, a guiding assembly 130 disposed on one side of the feeding box 105 for guiding tail material flow, a rinsing assembly 140 disposed in the feeding box 105 for rinsing tail material, a pneumatic assembly 150 disposed on one side of the support frame 101 for cleaning the conveyor belt 109, a limiting assembly 160 disposed in the connecting pipe 106 for limiting the pneumatic assembly 150, and a flow guiding assembly 170 disposed on one side of the connecting pipe 106 for guiding tail material flow.

[0042] The method of this magnetic separator includes the following steps:

[0043] S1. The tailings are fed into the feeding box 105 and then flowed into the first magnetic separator 102;

[0044] S2. The tail material is subjected to contact crushing treatment by the feeding component 120, which can perform preliminary crushing and refining treatment of the tail material.

[0045] S3. While being guided by the guide component 130, the material is also washed by the flushing component 140. The flushing process can be used to separate the tail material and promote its flow, which helps to further feed the raw material and perform magnetic separation.

[0046] S4. After the tailings enter the first magnetic separator 102, they are magnetically separated in the magnetic separator 108. The target raw materials and impurities can be initially separated. Then, they pass through the connecting pipe 106 and are separated from the impurities by the conveyor belt 109. The conveyor rollers on the conveyor belt 109 are equipped with a magnetic separation structure inside, which can be used for raw material conveying and preliminary separation.

[0047] S5. When the tail material in the connecting pipe 106 is conveyed by the conveyor belt 109, some tail material will remain on the conveyor belt 109. At this time, the pneumatic component 150 is used to clean and wash the residue on the conveyor belt 109 to avoid raw material residue. Then, it is circulated through the guide component 170 and conveyed to the second magnetic separator 103 for the next magnetic separation process.

[0048] S6. After being processed by the first magnetic separator 102, it is transported through the connecting pipe 106 and then to the second magnetic separator 103 and the third magnetic separator 104 for gradual magnetic separation.

[0049] Specifically, the feeding assembly 120 includes an extrusion shaft 121 disposed in the feeding box 105. An extrusion roller 122 is provided on the side wall of the extrusion shaft 121. Both ends of the extrusion shaft 121 are fixedly connected to a drive gear 123. A push tooth plate 124 is provided between the two drive gears 123. The drive gear 123 and the push tooth plate 124 cooperate. Both sides of the feeding box 105 are fixedly connected to a fixing frame 125. A guide groove 126 is opened on one side of the fixing frame 125. The push tooth plate 124 is slidably connected in the guide groove 126. A motor 127 is fixedly connected to one side of the feeding box 105. A drive gear 128 is fixedly connected to the output shaft of the motor 127. The drive gear 128 meshes with the drive gear 123 on one side.

[0050] The pusher tooth plate 124 meshes with the drive gears 123 on both sides, and drives the two drive gears 123 on both sides to rotate relative to each other, driving the two extrusion rollers 122 to contact, extrude and crush the tail material. This can be used to crush the tail material into particles before magnetic separation, which facilitates the subsequent magnetic separation process of the tail material.

[0051] The process involves three magnetic separators connected in series for iron separation. The first magnetic separator 102, the second magnetic separator 103, and the third magnetic separator 104 are respectively equipped with 3000GS, 2400GS, and 1500GS magnetic separators. The optimal magnetic declination angle for the 3000GS magnetic separator is 22° to the right; for the 2400GS magnetic separator, it is 21° to the right; and for the 1500GS magnetic separator, it is 18° to the right. The washing water angle of the magnetic separators is also specified. The optimal angle is 45° upwards; the optimal flushing water pressure is 0.2 MPa; the optimal feed slurry particle size is 82% (-325 mesh); the optimal feed concentration for a 3000GS magnetic separator is 39%; the optimal feed concentration for a 2400GS magnetic separator is 37%; and the optimal feed concentration for a 1500GS magnetic separator is 36%. The grade of iron concentrate produced by multi-stage magnetic separation of copper tailings from copper smelting slag can reach over 53%, which is more than 33% higher than the yield of the original ore before flotation.

[0052] Specifically, the guide assembly 130 includes connecting grooves 131 on both sides of the feeding box 105, which connect to the guide groove 126. A guide rod 132 is provided within the connecting groove 131, passing through the pusher tooth plate 124. A traction rod 133 is rotatably connected to one side of the drive gear 123. The traction rod 133 is eccentrically positioned on the drive gear 123, and the end of the traction rod 133 away from the drive gear 123 is rotatably connected to the pusher tooth plate 124. The flushing assembly 140 includes components fixedly connected to the feeding box 105. A water inlet tank 141 is located on one side, with a water inlet pipe 142 fixedly connected to one side. A bonding box 143 is fixedly connected to the inside of the feeding box 105. A water spray groove 144 is provided on one side of the bonding box 143. Swing frames 145 are rotatably connected to both sides of the bonding box 143. A shaking frame 146 is fixedly connected between the two swing frames 145 on one side. A connecting groove 134 is provided on one side of the swing frame 145. A movable shaft 135 is rotatably connected to the connecting groove 134. The movable shaft 135 is rotatably connected to the pusher tooth plate 124.

[0053] In use, the tailings are first fed into the feeding box 105. The motor 127 drives the drive gear 128 to mesh with the active gear 123 on one side. At this time, the active gear 123 drives the extrusion shaft 121 and the extrusion roller 122 to extrude and crush the tailings that have entered the feeding box 105. At this time, the active gear 123 meshes with the push tooth plate 124. Through the cooperation of the connecting groove 134 and the movable shaft 135, the swing frame 145 and the shaking frame 146 swing back and forth. At this time, water enters through the water inlet pipe 142 and the water inlet tank 141 and is sprayed out through the water spray trough 144 to wash the tailings with water. The tailings enter the first magnetic separator 102 and undergo the first magnetic separation treatment through the magnetic separation cylinder 108. Then, the tailings circulate through the connecting pipe 106. At this time, the conveyor belt 109 transports and transfers the tailings to the second magnetic separator 103 for secondary magnetic separation treatment.

[0054] In summary, by setting up a targeted crushing device before the tailings enter the subsequent magnetic separation stage, large particles of tailings are crushed to a suitable particle size. This not only fully exposes the magnetic materials in the tailings, which is conducive to more efficient capture and separation by the subsequent magnetic separator, significantly improving the recovery rate of magnetic products and reducing resource waste, but also avoids interference from large particles of tailings on the magnetic separation accuracy, improves product purity, and meets the stringent quality requirements of high-end industrial applications for magnetic products.

[0055] Example 2

[0056] Reference Figures 5-9 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a multi-stage magnetic separation process control method, which solves the problem of conveyor belt tail material adhesion and inconvenient cleaning. It includes a pneumatic component 150 passing through a push tube 151 of a sliding connection fixing frame 125. The push tube 151 is slidably connected to a guide rod 132. A propulsion cylinder 152 is fixedly connected to one side of the mounting frame 107. One end of the push tube 151 is fixedly connected to the air inlet piston of the propulsion cylinder 152. The air outlet end of the propulsion cylinder 152 is fixedly connected to an air pipe 153. One end of the air pipe 153 is connected to a connecting cylinder 154. The telescopic end of the connecting cylinder 154 is fixedly connected to a moving frame 155. Cleaning rollers 156 are provided on both sides of the conveyor belt 109. The cleaning rollers 156 are rotatably connected inside the connecting tube 106. Two symmetrically arranged connecting gears 158 are provided on the side wall of the cleaning rollers 156. Moving toothed plates 157 are fixedly connected to both sides of the moving frame 155. The moving toothed plates 157 mesh with the connecting gears 158.

[0057] Specifically, the limiting assembly 160 includes two symmetrically arranged limiting shafts 162 rotatably connected to the inner wall of the connecting pipe 106, and a limiting groove 161 is opened on one side of the moving frame 155, through which the limiting shafts 162 pass.

[0058] Furthermore, the flow guiding assembly 170 includes an inclined groove 171 disposed on one side of the connecting pipe 106, and a flow guiding groove 172 disposed on one side of the connecting pipe 106, with the inclined groove 171 communicating with the flow guiding groove 172.

[0059] During operation, the tailings after magnetic separation by the first magnetic separator 102 flow through the connecting pipe 106. At this time, the rotation of the drive gear 123 drives the traction rod 133 to swing, engaging with the pusher plate 124, causing the pusher pipe 151 to move downwards. This downward movement of the pusher pipe 151 compresses the pusher cylinder 152. One end of the pusher cylinder 152 compresses and delivers air through the air pipe 153 into the connecting cylinder 154, causing the connecting cylinder 154 to extend and retract. Under the limiting guidance of the limiting groove 161 and the limiting shaft 162, the moving frame 155 can be driven to reciprocate within the connecting pipe 106. The moving frame 155 moves, and the moving toothed plates 157 on both sides of the moving frame 155 mesh with the connecting gear 158, driving the cleaning roller 156 to rotate in the up and down direction of the conveyor belt 109. At this time, the cleaning roller 156 performs contact cleaning on both sides of the conveyor belt 109. At this time, part of the cleaned tail material is conveyed to the next magnetic separator through the conveyor belt 109. The tail material located below, after cleaning, is driven by the rinsing water and flows through the inclined trough 171 to the guide trough 172, and then flows through the connecting pipe 106 to the next magnetic separator, completing the cleaning and conveying of the tail material on the conveyor belt 109.

[0060] In summary, the present invention includes a cleaning roller 156, a movable toothed plate 157, a movable frame 155, an inclined groove 171, a guide groove 172, and a propulsion cylinder 152. During the tail material conveying process, this process control method fully considers the cleaning problem of the conveyor belt 109. By setting an automatic cleaning device on the conveyor belt 109, the material adhering to the conveyor belt 109 is removed in time, avoiding material residue from causing wear on the conveyor belt 109, effectively extending the service life of the conveyor belt 109, and reducing the cost of replacing the conveyor belt 109.

[0061] In summary, keeping the conveyor belt 109 clean helps maintain the stable operation of the conveying equipment. If there is a large amount of material residue on the conveyor belt 109, it will cause the conveyor belt 109 to run unbalanced, increasing the load on drive components such as the motor 127 and affecting the overall performance of the equipment. A clean conveyor belt 109, on the other hand, makes the conveying process smoother, reduces equipment failures caused by problems with the conveyor belt 109, ensures the continuous and stable operation of the multi-stage magnetic separation process, further improves production efficiency, reduces production stoppages caused by equipment failures, and creates greater economic benefits for the enterprise.
