Description

Technical Field

[0001] This utility model relates to the field of electrolytic manganese resource utilization technology, specifically to a device for recovering manganese ions from electrolytic manganese slag. Background Technology

[0002] Electrolytic manganese, with its high purity, has become a key element in enhancing the hardness of alloy materials and is widely used in various alloy fields. Its core applications and functions are reflected in three main types of alloys: in manganese-copper and manganese-aluminum alloys, manganese significantly enhances the alloy's strength and toughness, while also improving wear resistance and extending the service life of alloy products. In 200 series stainless steel, manganese not only improves the strength of stainless steel but also enhances its corrosion resistance, making it suitable for more complex environments. Overall, high-purity electrolytic manganese, by improving the mechanical properties and chemical stability of alloys, has become an indispensable and important component in the aforementioned alloy materials.

[0003] Traditional leaching stirring devices mostly use simple mechanical stirring, resulting in insufficient contact between manganese slag particles and the leaching agent. This leads to a slow dissolution rate of manganese ions and low leaching efficiency. The leached manganese slag slurry has high viscosity and fine solid particles, which easily clogs the filter cloth or screen during filtration. This not only causes a sharp drop in filtration speed, requiring frequent shutdowns for cleaning, but also results in a large amount of manganese-containing liquid remaining in the separated filter cake, causing a loss of manganese ions. Summary of the Invention

[0004] To solve the above-mentioned technical problems, a device for recovering manganese ions from electrolytic manganese slag is provided. This technical solution solves the problems of poor efficiency of single stirring treatment and easy clogging of filter components mentioned in the background technology.

The interior of the first housing 1 is located on the left side of the bottom end of the mounting base 26. The first pipe 5 is installed at the rear end of the outer surface of the first nozzle 18, and the top end of the outer surface penetrates the outer surface of the first housing 1. The steam generator 4 is fixedly installed at the top end of the outer surface of the first pipe 5, and the bottom end of the outer surface is installed at the top end of the first housing 1. The inlet 7 is installed on the rear side of the top end of the outer surface of the first housing 1. The connecting pipe 19 is installed inside the first housing 1 on the right side of the bottom end of the mounting base 26. A third valve 20 is installed at the middle of the outer surface of the connecting pipe 19. A second housing 10 is fixedly installed on one side of the outer surface of the connecting pipe 19. A partition 11 is installed in the middle of the interior of the second housing 10, and the axial surface of the connecting pipe 19 is connected to the upper side of the second housing 10.

[0017] The above scheme uses a first housing 1 as its core. A motor 6 is fixedly mounted on its top, and the output end of the motor 6 passes through the housing and connects to a rotating rod 16. Multiple sets of blades 17 are mounted on the rod for stirring the manganese slag and leachate. Inside the first housing 1, below the rotating rod 16, is a mounting ring 22, which contains a filter plate 23 for solid-liquid separation. The bottom of the mounting ring 22 is supported by a mounting base 26. Vibrators 25 in the mounting slots on both sides of the base can drive vibrating rods 24 to lift the filter plate 23, causing it to vibrate at high frequency to prevent clogging. A first nozzle 18 is located on the lower left side of the mounting base 26, connected to a steam generator 4 on the top of the housing via a first pipe 5, allowing steam to be injected to wash the filter residue. A feed inlet 7 is located on the rear top of the housing for feeding. The filtered manganese ion-containing filtrate flows out through a connecting pipe 19 on the lower right side of the mounting base 26. This connecting pipe 19 is equipped with a third valve 20 to control the flow rate, and its outlet is connected to the upper part of the second housing 10.

[0018] Reference Figure 1-3As shown, a first valve 12 is installed at the top of the outer surface of the partition 11. Several sets of heating rods 15 are installed inside the second housing 10 at the top of the partition 11. A discharge pipe 13 is installed at the bottom right side of the outer surface of the second housing 10. A second valve 14 is fixedly installed on the axial surface of the discharge pipe 13. A second pipe 8 is inserted into the rear end of the second housing 10 at the top side of the partition 11. A liquid pump 9 is installed on the axial surface of the second pipe 8. A second nozzle 21 is installed at the top of the outer surface of the second pipe 8 through the outer surface of the first housing 1. A base block 2 is installed at the bottom of the outer surface of the first housing 1. Several sets of fixing rods 3 are fixedly installed at the bottom of the outer surface of the base block 2.

[0019] With the above scheme, the evaporation and concentration unit of this device is centered on the second chamber 10. Its interior is divided into upper and lower chambers by a partition 11, with a first valve 12 installed on the partition 11 to connect the upper and lower chambers. Several heating rods 15 are installed in the upper chamber to heat and concentrate the flowing manganese-containing filtrate. To achieve recycling or discharge of the concentrated liquid, a second pipe 8 is inserted at the rear end of the second chamber 10, above the partition 11. This pipe is equipped with a liquid pump 9, whose outlet extends back into the first chamber 1 and is equipped with a second nozzle 21. Furthermore, a discharge pipe 13 is installed at the lower right bottom of the second chamber 10, with a second valve 14 installed on the pipe for the final discharge of the high-concentration manganese ion recovery liquid.

[0020] Working principle and implementation method: The pretreated electrolytic manganese slag and leaching solution are fed into the first tank 1 through the feed inlet 7. The motor 6 is started, driving the rotating rod 16 and the blade 17 to rotate, which fully stirs the mixture to accelerate the dissolution of manganese ions from the slag into the leaching solution. After stirring and leaching is completed, the solid-liquid mixture falls onto the filter plate 23 for solid-liquid separation. At this time, the two vibrators 25 installed on the mounting base 26 are started, and high-frequency vibration is transmitted to the mounting ring 22 and the filter plate 23 through the vibrating rod 24. This vibration can effectively prevent fine particles from clogging the filter holes, ensuring that the manganese ion solution in the filtrate passes smoothly, while the solid residue is trapped on the filter plate 23. During or in the later stage of filtration, the steam generator 4 can be turned on. The generated steam is sprayed out from the first nozzle 18 through the first pipe 5 to purge and wash the filter residue on the filter plate 23 to remove and recover the residual manganese ions, further improving the recovery rate. The manganese ion-containing filtrate obtained after filtration is collected at the bottom of the first tank 1. Open the third valve 20 on the connecting pipe 19. The filtrate flows into the upper chamber of the second tank 10 under gravity or negative pressure. Inside the second tank 10, the heating rod 15 heats the flowing filtrate, causing the water to evaporate and thus continuously increasing the manganese ion concentration to obtain a concentrated solution. In the initial stage of concentration or when it is necessary to increase the initial leachate concentration, the liquid pump 9 can be started to pump the concentrated solution in the upper chamber of the second tank 10 back to the first tank 1 through the second pipe 8, and spray it out through the second nozzle 21 for a new round of manganese slag leaching process, realizing the recycling of materials. When the concentrated solution reaches the predetermined concentration, the first valve 12 on the partition 11 can be opened to allow the concentrated solution to flow into the lower chamber of the second tank 10 for temporary storage. Finally, open the second valve 14 on the discharge pipe 13 to discharge and collect the high-concentration manganese ion recovery solution as a product.
