Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a device for recovering insoluble manganese from electrolytic manganese slag. Background Technology

[0002] The manganese slag produced during electrolytic manganese production contains abundant manganese components, including manganese oxide and manganese carbonate. These manganese substances are usually insoluble and difficult to process using traditional dissolution methods. Recycling these manganese resources can not only reduce the demand for natural resources but also lower waste disposal costs for enterprises. Traditional magnetic separation equipment is mainly drum-type magnetic separators, which use strong magnetic fields to adsorb magnetic minerals and separate magnetic and non-magnetic substances. Drum-type magnetic separators are widely used for separating strongly magnetic minerals such as iron ore and titanium ore. However, when processing weakly magnetic minerals such as electrolytic manganese slag, the magnetic field strength of drum-type magnetic separators is usually around 2000 Gauss, making it difficult to effectively separate weakly magnetic minerals such as manganese carbonate. To achieve higher magnetic field strengths, expensive customized magnetic separation equipment is often required, increasing costs. Drum-type magnetic separators are suitable for processing dry particles, but electrolytic manganese slag usually has a high moisture content, and direct dry magnetic separation can easily cause equipment blockage. In addition, the fine manganese slag particles are difficult to distribute evenly on the drum, resulting in poor separation effects. Drum magnetic separators require frequent maintenance during operation, especially when processing manganese slag with high water content, as the magnetic separation drum is prone to wear, leading to increased equipment maintenance costs.

[0003] The patent "Drum-type Magnetic Separator" (publication number CN205413342U, hereinafter referred to as Prior Art 1) discloses a drum-type magnetic separator. Prior Art 1 employs magnetic separation technology based on an electromagnet system, achieving material separation by controlling the on / off state of the current. This technology utilizes the magnetic attraction and repulsion between the magnetic separator drum and the magnetic material to effectively separate non-magnetic and magnetic materials.

[0004] However, the magnetic field strength of the drum magnetic separator described in prior art 1 is generally set at around 2000 Gauss, which is insufficient for separating weakly magnetic minerals like manganese carbonate. To achieve higher magnetic field strengths, such as 8000 Gauss or even 16000 Gauss, it is usually necessary to customize expensive magnetic separation equipment, which undoubtedly increases the overall cost. Furthermore, drum magnetic separators are mainly suitable for processing dry particles, but electrolytic manganese slag often contains high moisture content, and direct dry magnetic separation can easily lead to equipment blockage. Moreover, due to the small size of the electrolytic manganese slag particles, they are difficult to distribute evenly on the drum, further affecting the separation effect. During operation, drum magnetic separators require frequent maintenance, especially when processing manganese slag with high moisture content, as the magnetic separation drum is prone to wear, which not only increases the maintenance cost of the equipment but may also affect its stable operation.

[0005] In view of this, the present invention provides a device for recovering insoluble manganese from electrolytic manganese slag, in order to solve the problem that the conveying system of the magnetic separator in the prior art is usually fixed and cannot be adjusted according to different working conditions and material characteristics, resulting in poor material adaptability.

[0031] Example 1

[0032] Please see Figure 1 This utility model provides a device for recovering insoluble manganese from electrolytic manganese slag. The main function and purpose of this device is to extract valuable manganese from electrolytic manganese slag, a byproduct of the electrolytic manganese production process, thereby achieving effective recovery of these valuable components. Electrolytic manganese slag typically contains a certain proportion of insoluble manganese, such as manganese oxides and sulfides. The recovery and utilization of this insoluble manganese not only significantly improves the comprehensive utilization rate of resources but also plays a crucial role in reducing environmental pollution. By effectively recovering manganese from electrolytic manganese slag, the utilization efficiency of manganese resources can be improved, thereby reducing the demand for manganese ore mining. If measures are not taken to recover the insoluble manganese from this electrolytic manganese slag, it will be discharged into the environment as solid waste, which may cause serious environmental pollution. Therefore, by recovering and utilizing manganese, the generation of such solid waste can be effectively reduced, thus protecting the environment while achieving sustainable resource utilization.

[0033] Please see Figure 1In this embodiment, an apparatus for recovering insoluble manganese from electrolytic manganese slag includes a frame 100 and a conveying mechanism and a driving mechanism mounted on the frame 100. The conveying mechanism provides power to transport the electrolytic manganese slag via the driving mechanism. The conveying mechanism continuously transports the electrolytic manganese slag to a designated location for magnetic separation in a magnetic separation zone to achieve the purpose of recovering insoluble manganese from the electrolytic manganese slag. Magnetic separation mainly uses magnets 320 to distinguish the physical or chemical properties of different materials in the electrolytic manganese slag, thereby recovering valuable components. Specifically, manganese is usually separated from other impurities (such as silicon, iron, aluminum, calcium, etc.) to recover insoluble manganese (e.g., manganese oxides, manganese sulfides, etc.) for further utilization.

[0034] Please see Figure 1 In this embodiment, the frame 100 includes a support frame 110 and a mounting frame 120, which is mounted on the support frame 110. One end of the conveying mounting frame 120 is hinged to the support frame 110 via a mounting base 131, while the other end is hinged to the mounting frame 120 via a lifting mechanism 200. This design allows the conveying mechanism to be angled to adapt to different working environments and requirements. During magnetic separation, materials are typically separated into non-magnetic materials (tailings) and magnetic materials. The portion containing manganese generally exits from the top of the conveying mechanism, while the non-magnetic materials exit from the bottom. Therefore, the inclination of the conveying mechanism directly affects the discharge speed of the non-magnetic materials. By providing hinged portions at both ends of the mounting frame 120, the inclination of the conveying mechanism can be flexibly adjusted to meet the specific requirements of different magnetic separation operations. The mounting frame 120 is directly used to mount the conveying mechanism and drive mechanism, providing an adjustable platform with a certain distance from the ground for easy installation of material recovery equipment.

[0035] Please see Figure 1 In some specific embodiments, the lifting mechanism 200 may consist of at least one pair of cylinders, which are respectively mounted on both sides of the mounting frame 120. The piston rod of each cylinder is hinged to the bottom of the mounting frame 120. When it is necessary to adjust the tilt angle of the conveying device, the cylinder can be activated to control the extension or shortening of the piston rod, thereby achieving precise adjustment of the self-selected angle of the conveying device, adapting to manganese slag of different particle sizes and shapes, and realizing different magnetic separation operation conditions.

[0036] In some other specific embodiments, the lifting mechanism 200 can also be configured as a lifting platform. When the lifting platform is configured, one end of the mounting frame 120 is slidably installed with the lifting platform. When it is necessary to adjust its tilt angle, the lifting platform is driven to rise or fall. Therefore, the mounting frame 120 generates displacement based on the sliding with the lifting platform, thereby adjusting the tilt angle of the conveying mechanism and realizing the adjustment of the handling scheme for different situations.

[0037] Please see Figure 2 and Figure 3 In this embodiment, the conveying mechanism is equipped with a series of configuration components to ensure efficient material conveying. Specifically, the conveying mechanism includes a first roller 311 and a second roller 312 disposed at both ends of the mounting frame 120. These two rollers are one of the core components of the conveying mechanism. They can withstand a certain load and maintain stable operation during the conveying process. In addition, the conveyor belt 313 sleeved on the first roller 311 and the second roller 312 works closely with the rollers to ensure that the material can pass smoothly through the conveying mechanism.

[0038] Please see Figure 1 The conveyor belt 313 contacts the first rotating roller 311 and the second rotating roller 312, and this contact is crucial for power transmission during the conveying process. When the conveying mechanism begins its conveying operation, the conveyor belt 313 moves accordingly through the synchronous rotation of the first rotating roller 311 and the second rotating roller 312. This movement is continuous, ensuring that the material can be effectively discharged after magnetic separation. The entire conveying process is automated and continuous, greatly improving the efficiency and speed of material handling.

[0039] Please see Figure 1In this embodiment, the conveyor belt 313 includes a cavity formed by fitting the first roller 311 and the second roller 312 together. Inside the cavity, a magnet 320 is installed. This magnet 320 is a permanent magnet, a special magnetic material capable of continuously generating a magnetic field without relying on an external power source or any excitation mechanism. The permanent magnet generates a magnetic field due to its inherent natural magnetic distribution and the magnetic properties of the material itself, enabling it to produce a stable magnetic field. In this application, the magnetic field strength generated by the permanent magnet is set within the range of 8000 to 16000 Gauss, a parameter crucial for the magnetic separation process. Magnetic separation is a process that uses a magnetic field to separate different materials. In this process, when materials containing ferromagnetic components, such as electrolytic manganese slag (usually a mixture), pass through the magnetic separation zone, those containing ferromagnetic components, such as manganese minerals, are attracted by the strong magnetic field due to their magnetism. Meanwhile, non-ferromagnetic materials, such as silica sand and limestone impurities, are not affected by the magnetic field because they lack magnetism. Since manganese minerals are typically highly magnetic, they are attracted by the magnetic field and move along the surface of the magnet, while non-magnetic impurities are carried away by gravity. In this embodiment, the permanent magnet is disposed inside the conveyor belt 313, and its position ensures that the conveying path of the conveyor belt 313 is completely covered by the magnetic field lines of the permanent magnet. Therefore, during magnetic separation, the conveying path of the conveyor belt 313 is perfectly aligned with the direction of the magnetic field lines generated by the permanent magnet, thus ensuring the efficiency and effectiveness of the magnetic separation process.

[0040] Furthermore, permanent magnets are typically composed of rare earth elements (such as neodymium, iron, and boron), possessing strong magnetic force. These materials enable the magnets to generate a continuous and powerful magnetic field, which remains stable during long-term use of the equipment and does not decay due to external factors. Using rare earth permanent magnet materials ensures long-term stable operation of the equipment, reducing the frequency of maintenance and replacement. Permanent magnets are typically available in various shapes, such as strips, rectangles, rings, and cylinders, with the specific design depending on the spatial layout of the magnetic separation area. In this embodiment, the permanent magnets are arranged in rectangular blocks to ensure that the magnetic field is evenly distributed across the material flow area. The permanent magnets are installed below the material conveyor belt to ensure that the material experiences sufficient magnetic force as it passes through the magnetic field area, effectively separating magnetic minerals (such as manganese).

[0041] In this embodiment, permanent magnets are used, unlike electromagnets. Permanent magnets do not require a power supply, thus offering a significant advantage in energy efficiency. The magnetic field of the device is provided by the magnet itself, eliminating the need for additional electrical energy consumption. This reduces energy consumption and lowers the operating cost of the equipment. The use of permanent magnets not only reduces energy consumption but also avoids electromagnetic radiation and thermal effects, making it more environmentally friendly and in line with the trend of green mining production.

[0042] Please see Figure 1 In this embodiment, the two ends of the magnet 320 are mounted via mounting brackets 120, ensuring that the magnet 320 is fixed in a predetermined position. This allows the magnet 320 to effectively control the movement path of the magnetic material during the conveying operation of the conveying mechanism. The conveying mechanism itself includes a drive motor 410, whose output shaft 411 is connected to the first roller 311 of the conveying mechanism. The conveyor belt 313 is designed with high friction between itself and the first roller 311 and the second roller 312 of the conveying mechanism to ensure stable contact between the conveyor belt 313 and the rollers. When the drive motor 410 starts, its output shaft 411 drives the first roller 311 to rotate, thereby driving the conveyor belt 313 to move through friction. The movement of the conveyor belt 313 is based on the combined action of the first roller 311 and the second roller 312, ensuring that the conveyor belt 313 maintains a stable movement state during the conveying process.

[0043] Please see Figure 1 A feeding mechanism is installed at one end of the mounting frame 120. The discharge port 511 of this feeding mechanism is located at one end of the conveyor belt 313, ensuring that materials can smoothly enter the conveying system. The feeding mechanism is positioned above the conveyor belt 313, allowing materials to be continuously fed into the equipment, thus ensuring the continuity of the entire magnetic separation process. Furthermore, the feeding mechanism is positioned at a relatively high position during the magnetic separation process, which facilitates the smooth downward flow of non-magnetic materials under gravity, making subsequent recycling and processing easier.

[0044] Please see Figure 2 and Figure 3 The mounting frame 120 is provided with four bearing seats, namely a first bearing seat 132, a second bearing seat 133, a third bearing seat 134 and a fourth bearing seat 135. These bearing seats are arranged at both ends of the mounting frame 120, wherein the first bearing seat 132 and the second bearing seat 133 are located on both sides of one end of the mounting frame 120, while the third bearing seat 134 and the fourth bearing seat 135 are arranged on both sides of the other end of the mounting frame 120.

[0045] Furthermore, the two ends of the first roller 311 are tightly connected to the first bearing seat 132 and the second bearing seat 133, respectively, ensuring the stability and flexibility of the first roller 311. Similarly, the two ends of the second roller 312 are connected to the third bearing seat 134 and the fourth bearing seat 135, respectively, thereby enabling the smooth rotation of the second roller 312. Through this reasonable layout and arrangement of the bearing seats, the first roller 311 and the second roller 312 can effectively complete the material conveying work, while ensuring the stability and reliability of the entire conveying process.

[0046] Please see Figure 1 In this embodiment, the middle part of the mounting frame 120 is configured to protrude to both ends; and, in the middle protruding part of the mounting frame 120, a pair of auxiliary rollers 314 that contact the conveyor belt 313 are respectively provided.

[0047] In the middle section of the conveyor belt 313, the belt may sag or deform due to the weight of the material and friction during conveying. To address this issue, auxiliary rollers 314 are installed in the middle section of the conveyor belt 313. These auxiliary rollers 314 provide additional support, effectively preventing excessive belt sag and ensuring the belt maintains a flat and stable operation. These auxiliary rollers 314 are evenly distributed in the middle area of ​​the belt, enabling a more uniform tension distribution during conveying and preventing material accumulation or obstructed conveying due to uneven belt tension. During long-term operation, especially when material passes over the belt, the conveyor belt 313 often experiences friction with the belt surface, leading to belt wear. The auxiliary rollers 314 help to share some of the weight friction, thereby reducing the friction between the belt surface and the material in direct contact and extending the belt's service life. Due to the presence of the auxiliary rollers 314, the belt will not be excessively stretched or deformed when bearing the weight of the material, further reducing the risk of wear and damage.

[0048] During magnetic separation, the material needs to be evenly distributed on the conveyor belt 313 to ensure the effective action of the magnetic field on all materials. The auxiliary roller 314 helps to ensure the consistency of material distribution by providing appropriate material support and uniform conveying, thereby enhancing the magnetic separation effect and preventing material accumulation from affecting the separation effect.

[0049] Please see Figure 1In this embodiment, a cleaning mechanism is also provided, which consists of a first cleaning section 610 and a second cleaning section 620. The first cleaning section 610 is located at the top of the support frame 110, while the second cleaning section 620 is located at one end of the support frame 110. The core components of this cleaning mechanism include a water supply pipe 631 and cleaning nozzles 632 connected to the water supply pipe 631. The function of these cleaning nozzles 632 is to effectively clean the material on the conveyor belt 313.

[0050] The first cleaning is performed at the material outlet 511. The main function of the first cleaning section 610 is to remove large particulate impurities from the material. The primary purpose of the first cleaning is to preliminarily rinse the manganese slag to remove larger impurities and scum. Since manganese slag often contains coarse particles, useless mineral impurities, or impurities floating on the surface, these impurities, if not removed, will seriously affect the subsequent magnetic separation effect. Through the first cleaning, larger impurities are removed in advance, thus preventing these impurities from entering the magnetic material recovery area. After the material is cleaned, the material entering the magnetic separation area becomes cleaner, reducing the interference of impurities and making the manganese component separation process more accurate and efficient.

[0051] The second cleaning is performed in the magnetic separation zone or after magnetic separation. The purpose of the second cleaning is to finely rinse the material after magnetic separation to remove residual small particulate impurities, especially those fine impurities that have not been effectively separated by the magnetic field. These fine impurities are usually materials with a similar manganese composition and are difficult to separate by magnetic separation; therefore, a second cleaning is necessary to improve the purity of the material. The second cleaning can further increase the manganese content of the recovered material and reduce the impurity content. This makes the final magnetically separated product purer, facilitating subsequent processing or direct utilization. Furthermore, some impurities may adhere to or be hidden between manganese particles; the second cleaning effectively removes these fine impurities, thereby ensuring maximum manganese recovery and improving the accuracy of sorting.

[0052] Please see Figure 1 The first cleaning unit 610 and the second cleaning unit 620 are designed with the width of the conveyor belt 313 in mind, ensuring that all materials on the conveyor belt 313 can be thoroughly cleaned, thereby achieving wet magnetic separation. Furthermore, after cleaning in the first cleaning unit 610, non-magnetic materials can be discharged using the cleaning fluid, ensuring the continuity and efficiency of the cleaning process.

[0053] Furthermore, the nozzles of the first cleaning unit 610 are designed to spray water vertically for cleaning. When materials are being conveyed, the cleaning water is at a certain angle to the conveyor belt 313 for cleaning. This design makes the cleaning effect better and can more effectively remove impurities from the surface of the materials.

[0054] Please see Figure 4 The mounting frame 120 is also provided with a motor frame 136 for mounting the motor; the drive motor 410 is mounted on the motor frame 136; in order to achieve effective driving of the conveying mechanism, the output shaft 411 of the drive motor 410 is equipped with a drive gear 412, and the first rotating roller 311 that cooperates with it is equipped with a driven gear 413; these two gears are tightly connected by a transmission chain 414, thereby ensuring that the conveying mechanism can operate smoothly and efficiently.

[0055] To ensure the safety and stability of the drive gear 412, driven gear 413, and transmission chain 414 during operation, protective covers 415 are provided on the outside of these components. These protective covers 415 are firmly fixed to the motor frame 136, thereby providing an additional protective layer for the drive part and preventing external factors from damaging these critical components.

[0056] Please see Figure 1 The feeding mechanism includes a feeding box 510 and a discharge port 511 communicating with the feeding box 510. The feeding box 510 is installed at the top of the conveyor belt 313, which facilitates the feeding of materials onto the conveyor belt 313 for subsequent processing. At both ends of the conveyor belt 313, a first material outlet and a second material outlet are respectively provided. These two outlets are used to discharge non-magnetic materials and magnetic materials, respectively, thereby achieving classified output of materials and enabling the effective separation and collection of non-magnetic and magnetic materials.

[0057] Please see Figure 1In operation, the conveying mechanism must first be adjusted to a predetermined angle via the lifting mechanism 200, and then the conveying mechanism, cleaning mechanism, and feeding mechanism are started. During this stage, the material is evenly discharged from the discharge port 511 in the feeding box 510 and smoothly transferred to the conveyor belt 313. During magnetic separation, the conveyor belt 313's movement speed is set relatively slowly, causing the material to flow towards the lower end of the conveying mechanism due to gravity. Since the magnetic field of the permanent magnet covers the entire conveyor belt 313, magnetic materials move towards the higher end along the direction of the magnetic field lines. Simultaneously, non-magnetic materials, which may have some stickiness, may adhere to the conveyor belt 313 and move towards the higher end as the belt moves. When the material passes through the first cleaning section 610, a first cleaning is performed to wash away large, sticky, non-magnetic particles from the conveyor belt 313. These materials are discharged from the conveyor belt 313 by gravity and exit from the first material outlet for collection. As for the magnetic materials, they will undergo a second cleaning process to remove any remaining fine impurities from the magnetic materials after magnetic separation. After this step, the magnetic materials will be discharged from the second material outlet and collected.

[0058] Furthermore, some components of manganese minerals may be magnetic, but their particle size is relatively large, or they are tightly bound to other materials (such as impurities). In this case, the manganese component may be affected by the magnetic field generated by the permanent magnet, but it is not easily directly attracted to the magnet surface. Instead, these particles are carried into the magnetic separation area by the material flow direction and gravity, and gradually moved by magnetic force. For larger magnetic particles, the magnetic force is insufficient to attract them immediately; instead, the particles move along the direction of the magnetic field lines and are eventually collected at a specific location.

[0059] Since this equipment achieves wet magnetic separation through a cleaning mechanism, the material is transported in fluid form on the conveyor belt 313, and the water flow plays a crucial role in the material's movement. Under the influence of water, the material (including manganese particles) passes through the magnetic separation zone in liquid form. In this environment, magnetic particles (such as manganese) are not directly adsorbed onto the magnet as in dry magnetic separation, but are instead attracted by magnetic force and propelled by the water flow along the magnetic field lines or discharged.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
