Description

Technical Field

[0001] This invention relates to the technical field of cobalt manganese acetate preparation, and more particularly to an apparatus for preparing cobalt manganese acetate by recycling cobalt and manganese residue resources. Background Technology

[0002] Cobalt-manganese residue is a typical industrial solid waste generated by the chemical, metallurgical, and new energy industries. Rich in high-value metals such as cobalt and manganese, direct landfilling or indiscriminate dumping not only results in a serious waste of valuable metal resources but also pollutes soil and groundwater, posing significant environmental risks. Currently, the industry's recycling and treatment technology for cobalt-manganese residue is relatively rudimentary, often employing simple crushing followed by direct acid leaching. This approach has significant technical shortcomings: traditional crushing equipment struggles to finely crush the residue to a suitable particle size, resulting in uneven particle size and small specific surface area, leading to low efficiency in subsequent acid leaching reactions; the residue often contains ferromagnetic impurities, which directly affect the purity of cobalt-manganese acetate products when introduced into the acid leaching process, increasing the difficulty of subsequent purification; furthermore, the residue's dense mineral lattice and poor reactivity make it difficult to achieve efficient leaching of cobalt and manganese metals using conventional acid leaching methods, resulting in generally low leaching rates. In addition, existing processes are mostly single-reactor batch production, with low acid utilization rate, high energy consumption, and lack of continuous and intelligent control, resulting in poor production stability and difficulty in achieving large-scale and efficient resource utilization of cobalt and manganese residues. There is an urgent need to develop a special device that integrates crushing, iron removal, activation, and continuous acid leaching to solve the above-mentioned industry pain points.

Detailed Implementation

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] 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.

[0031] Secondly, the term "one 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 in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0033] Reference Figures 1-9As an embodiment of the present invention, an apparatus for preparing cobalt manganese acetate by recycling cobalt manganese residue is provided, including a crushing component 100, an ultrasonic activation component 200, and an acid leaching component. The components are connected in series to form a complete cobalt manganese residue treatment process, which can realize efficient crushing, deep activation and continuous acid leaching of cobalt manganese residue, and improve the leaching rate and resource recovery rate of cobalt manganese metal.

[0034] Furthermore, the crushing component 100 is used to crush the cobalt-manganese residue to a suitable particle size to facilitate subsequent activation and acid leaching reactions. In this embodiment, the crushing component 100 includes a first crushing component 101, a second crushing component 102 connected to the first crushing component 101, and an iron removal component 103 disposed on the second crushing component 102.

[0035] The first crushing component 101 completes the coarse crushing of large cobalt manganese residue, initially decomposing the residue with larger particle size; the second crushing component 102 further crushes the coarsely crushed residue to the target particle size, increasing the specific surface area of ​​the residue; the iron removal component 103 simultaneously removes ferromagnetic impurities from the residue during the crushing process, preventing iron elements from entering subsequent processes and affecting the purity of the cobalt manganese acetate product.

[0036] In this embodiment, the first crushing component 101 includes a first crusher body 1011, a first crushing plate 1012 symmetrically arranged on the first crusher body 1011, and a feeding plate 1013 arranged at the lower end of the first crushing plate 1012. The first crushing plate 1012 is provided with a plurality of crushing patterns. There are two first crushing plates 1012, and their lower ends are close to each other and are both hinged to the first crusher body 1011.

[0037] Furthermore, a push cylinder 1014 is installed on the first crusher body 1011. The push cylinder 1014 is rotatably connected to the first crushing plate 1012. The extension and retraction of the push cylinder 1014 causes the two first crushing plates 1012 to swing relative to each other, crushing large cobalt-manganese residue through the crushing grooves. The crushed residue is then conveyed to the second crushing component 102 via the feeding plate 1013. The swing-type crushing structure driven by the push cylinder 1014 can adapt to large residues of different sizes, and the crushing force is adjustable, effectively avoiding material jamming and machine stoppage. The crushing grooves increase the contact area with the residue, improve crushing efficiency, prevent residue slippage, and ensure uniform particle size after coarse crushing.

[0038] Furthermore, in this embodiment, the second crushing component 102 includes a support 1021 connected to the first crusher body 1011, a receiving disc 1022 rotatably connected to the support 1021, a vertical slide rod 1023 disposed on the support 1021, a slide cylinder 1024 slidably connected to the vertical slide rod 1023, a pressing block 1025 disposed on the slide cylinder 1024, and a driving component 104 disposed on the support 1021. An iron removal component 103 is disposed on the pressing block 1025, and two vertical slide rods 1023 and two slide cylinders 1024 are respectively provided. The receiving disc 1022 is used to receive the coarsely crushed residue conveyed by the first crushing component 101. The driving component 104 simultaneously drives the receiving disc 1022 to rotate and the pressing block 1025 to reciprocate up and down. The pressing block 1025 crushes the residue on the receiving disc 1022, achieving continuous fine crushing operation. Two vertical sliding rods 1023 work in conjunction with the sliding cylinder 1024 to guide the movement of the pressing block 1025, ensuring its smooth movement.

[0039] Furthermore, in this embodiment, the drive component 104 includes a first pulley 1041 and a second pulley 1042 rotatably connected to the bracket 1021, a worm gear 1043 coaxially connected to the first pulley 1041, and a worm wheel 1044 coaxially connected to the receiving disc 1022. The worm wheel 1044 meshes with the worm gear 1043. A crankshaft 1045 is coaxially provided on the second pulley 1042. A collar 1046 is rotatably connected to each of the two vertical slide rods 1023 corresponding to the crankshaft 1045. A connecting rod 1047 extends from the collar 1046 and is hinged to the slide cylinder 1024.

[0040] Preferably, the power source simultaneously drives the first pulley 1041 and the second pulley 1042 to rotate via belt drive. The first pulley 1041 drives the receiving disc 1022 to rotate via worm gear 1043 and worm wheel 1044, so that the residue is evenly distributed in the disc. The second pulley 1042 drives the crankshaft 1045 to rotate, which drives the slide cylinder 1024 to move up and down along the vertical slide rod 1023 via connecting rod 1047, thereby driving the pressing block 1025 to crush the residue. A single power source drives the two actions synchronously, and the worm gear 1043 and worm wheel 1044 transmission has self-locking property to prevent the receiving disc 1022 from reversing and to ensure stable rotation. The crankshaft 1045 drives the two slide cylinders 1024 to move synchronously, so that the pressing block 1025 is subjected to uniform force.

[0041] Preferably, a second belt assembly 1048 is coaxially connected to the second pulley 1042, and the second belt assembly 1048 is driven by a motor.

[0042] Furthermore, in this embodiment, the iron removal component 103 includes a cover baffle 1031 disposed on the receiving disc 1022, a plurality of rollers 1032 disposed at the lower end of the cover baffle 1031, an iron removal component 1033 disposed between the rollers 1032, and a conveyor belt 1034 covering between every two rollers 1032. The cover baffle 1031 has an opening, and an iron removal plate is slidably connected to the cover baffle 1031. A cylinder is disposed at the rear end of the iron removal plate. The finely crushed residue falls onto the conveyor belt 1034 and moves at a uniform speed with the conveyor belt 1034. The iron removal component 1033 adsorbs ferromagnetic impurities in the residue. When the impurities adsorbed by the iron removal component 1033 reach a certain amount, the cylinder pushes the iron removal plate to extend, scraping off and collecting the impurities on the iron removal component 1033.

[0043] Preferably, the cover baffle 1031 prevents residue from splashing during the rolling and iron removal process, ensuring a clean working environment; the conveyor belt 1034 conveys at a uniform speed to ensure that iron impurities are fully adsorbed, and the automatic scraping structure eliminates the need for manual cleaning, achieving continuous iron removal.

[0044] Furthermore, the ultrasonic activation component 200 is used to perform ultrasonic activation treatment on the crushed cobalt-manganese residue, thereby destroying the mineral lattice structure of the residue and improving the acid leaching reaction activity. It includes a slurry preparation component 201 connected to the second crushing component 102, a slurry cylinder 2011 connected to the slurry preparation component 201, an ultrasonic activation component 203 disposed on the slurry cylinder 2011, and an acid leaching component disposed at the lower end of the slurry cylinder 2011.

[0045] In this embodiment, the acid leaching component includes several horizontal stirred reactors 204 connected to the slurry cylinder 2011. A connecting pipeline is provided between the several horizontal stirred reactors 204. The slurry preparation component 201 mixes the crushed residue with water to prepare a uniform slurry. The ultrasonic activation component 203 performs ultrasonic cavitation treatment on the slurry. The activated slurry enters the horizontal stirred reactor 204 for continuous acid leaching reaction. The connecting pipeline realizes the continuous transportation of materials between multiple reactors.

[0046] The slurry preparation unit 201 includes a slurry cylinder 2011, a slurry delivery pipe 2012 mounted on the slurry cylinder 2011, a stirring rod 2013 installed inside the slurry cylinder 2011, an online concentration meter installed inside the slurry cylinder 2011, and an online pH meter installed inside the slurry cylinder 2011. A discharge pipe 2014 is located at the lower end of the slurry cylinder 2011, and a pump is mounted on the discharge pipe 2014. Crushed residue enters the slurry cylinder 2011, mixes with water, and the stirring rod 2013 rotates to agitate the mixture into a homogeneous slurry. The online concentration meter monitors the slurry concentration in real time, and the online pH meter monitors the slurry pH value in real time, facilitating timely adjustment of water addition and pH to ensure stable slurry parameters. The pump delivers the prepared slurry to the slurry cylinder 2011 through the discharge pipe 2014.

[0047] Furthermore, the ultrasonic activation component 203 includes an ultrasonic activation tank 2031 disposed within the slurry cylinder 2011, an ultrasonic generator 2032 disposed outside the ultrasonic activation tank 2031, and several baffles 2033 disposed within the ultrasonic activation tank 2031. The baffles 2033 include several stacked baffles with several baffle protrusions. The slurry enters from the upper end of the ultrasonic activation tank 2031 and flows downward in a tortuous path under the action of the baffles 2033, prolonging the residence time of the slurry in the ultrasonic field. The ultrasonic generator 2032 generates high-frequency ultrasonic waves, cavitating the slurry and generating microjets and shock waves, disrupting the mineral lattice structure of the cobalt-manganese residue and fully exposing the cobalt-manganese metal. The baffle protrusions further disrupt the slurry flow state, forming turbulence, making the slurry mixing more uniform.

[0048] The acid leaching component also includes an acid reverse delivery pipeline 205 disposed between adjacent horizontal stirred reactors 204. The activation slurry enters from the first horizontal stirred reactor 204 and flows sequentially to the next reactor through the material overflow pipeline. The acid is delivered from the last reactor to the next reactor through the acid reverse delivery pipeline 205, forming a countercurrent contact reaction. The countercurrent reaction causes the acid concentration to gradually increase from back to front, fully utilizing the acid, reducing acid consumption, and ensuring contact between low-concentration slurry and high-concentration acid, as well as between high-concentration slurry and low-concentration acid, allowing for the full leaching of cobalt and manganese metal.

[0049] Each horizontal stirred reactor 204 includes a reactor body 2041, a jacketed heating layer 2042 disposed on the outer wall of the reactor body 2041, a stirring device 300 rotatably connected inside the reactor body 2041, an activation slurry inlet and an acetic acid inlet located at the top of the reactor body 2041, and an overflow outlet 2043 located on the side wall of the reactor body 2041. The jacketed heating layer 2042 has a steam inlet and a condensate outlet. Each horizontal stirred reactor 204 is equipped with an online pH meter and a thermometer, both electrically connected to a central control system. Steam is introduced into the jacketed heating layer 2042 to heat the materials inside the reactor, maintaining the optimal temperature required for the acid leaching reaction. The stirring device 300 stirs the materials inside the reactor, ensuring full contact between the acid solution and the residue particles. The online pH meter and thermometer monitor the reaction parameters inside the reactor in real time. The central control system automatically adjusts the amount of acid added and the heating temperature, achieving automated control of the reaction process and ensuring stable reaction.

[0050] Each overflow outlet 2043 is equipped with an anti-clogging filter, which can trap large particles of residue that have not fully reacted.

[0051] The stirring device 300 includes a stirring shaft 301 rotatably connected within the vessel body 2041, an anchor-type stirring blade 302 fixed to the lower end of the stirring shaft 301, and a multi-layered paddle stirring blade 303 fixed to the middle of the stirring shaft 301. The anchor-type stirring blade 302 can scrape off the material adhering to the inner wall of the vessel body 2041, preventing material scaling from affecting heat transfer and reaction efficiency; the multi-layered paddle stirring blade 303 enhances the turbulence of the material inside the vessel, improves mass transfer efficiency, and ensures thorough mixing of acid and residue particles, accelerating the acid leaching reaction rate and making the reaction more complete. A spiral guide plate 304 is provided on the outer side of the stirring shaft 301, and the spiral guide plate 304 is spirally arranged along the axial direction of the vessel body 2041. The spiral guide plate 304 guides the steam to flow in a spiral shape within the jacket, prolonging the steam residence time, improving thermal energy utilization, and simultaneously ensuring uniform heating of all parts of the vessel body 2041, avoiding local overheating or undercooling, and ensuring a consistent reaction temperature.

[0052] Operation Process: Cobalt-manganese residue first enters the first crushing component 101, where a cylinder 1014 drives the first crushing plate 1012 to swing, completing coarse crushing. The coarsely crushed residue then enters the receiving plate 1022 of the second crushing component 102 via the feeding plate 1013. The driving component 104 drives the receiving plate 1022 to rotate, simultaneously causing the pressing block 1025 to reciprocate up and down to finely crush the residue. After the finely crushed residue passes through the iron removal component 103 to remove iron impurities, it enters the slurry preparation component 201 to be mixed with water to prepare a uniform slurry. The slurry is pumped to the ultrasonic activation tank 2031, where it undergoes activation treatment under ultrasonic waves. The activated slurry then sequentially enters multiple horizontal stirred reactors 204 to undergo a countercurrent acid leaching reaction with a counter-currently conveyed acetic acid solution. During the reaction, the jacketed heating layer 2042 maintains the reaction temperature, the stirring device 300 ensures uniform mixing of the materials, and the online monitoring equipment controls the reaction parameters in real time. The final cobalt manganese acetate leachate flows out from the overflow port 2043 of the last reactor and enters the subsequent purification process.
