Description

Technical Field

[0001] This utility model relates to the field of recycling equipment, and in particular to equipment for recycling electrolytic manganese slag. Background Technology

[0002] With the rapid development of the electrolytic manganese industry, a large amount of electrolytic manganese slag is generated. If this manganese slag is not effectively treated, it will not only occupy a large amount of land resources, but also cause serious pollution to the soil, water and atmospheric environment due to the heavy metals and other harmful substances it contains. Electrolytic manganese slag recycling equipment is an industrial equipment specially designed to recover valuable components from electrolytic manganese slag.

[0003] Most existing electrolytic manganese slag recycling equipment directly uses water to wash the electrolytic manganese slag without recycling the water resources. The water resources are not effectively recycled. In the electrolytic manganese slag treatment process, key steps such as screening and washing require the continuous introduction of fresh water. However, the water used is not recycled and reused. This one-way water use mode causes unnecessary loss of water resources.

[0004] Therefore, most existing electrolytic manganese slag recycling equipment relies on continuously introducing fresh water to directly wash the manganese slag during the screening and cleaning processes, without recycling or reusing the used water. This one-way water use leads to unnecessary water resource loss and fails to achieve effective recycling, deviating from the current concept of sustainable development. To address this, an electrolytic manganese slag recycling equipment can be designed to fully recover valuable components from the electrolytic manganese slag through a series of processes such as crushing, screening and filtration, and high-temperature recovery, thereby improving resource utilization and constructing a complete water circulation path. This allows the water used in screening and cleaning processes to be treated sequentially through sedimentation and chemical filtration before returning to the screening and filtration box for recycling. Utility Model Content

[0005] In order to overcome the problem that most existing electrolytic manganese slag recycling equipment relies on the continuous introduction of fresh water to directly wash the manganese slag in the screening and cleaning processes, without recycling and reusing the water after use, this one-way water use mode leads to unnecessary water loss and fails to achieve effective recycling, which deviates from the current concept of sustainable development.

[0006] The technical solution of this utility model is as follows: an electrolytic manganese slag recovery equipment, including an installation platform, a feeding hopper, a crushing box, a screening and filtering box, and a high-temperature recovery furnace; a feeding hopper for feeding materials into the device is installed at the top of the installation platform, a crushing box for crushing materials is installed at one end of the installation platform, a screening and filtering box for removing impurities and metal ions is connected to one side of the crushing box, a high-temperature recovery furnace for heating and recovering materials is connected to one side of the screening and filtering box, a sedimentation tank is connected to the lower part of the outside of the screening and filtering box, a chemical filter box is connected to one end of the sedimentation tank, a circulation pipe is connected to the top of the chemical filter box, and the other end of the circulation pipe is connected to the screening and filtering box.

[0007] Preferably, when the electrolytic manganese slag recovery equipment is working, the electrolytic manganese slag first enters the device through the feed hopper, and then the material enters the crushing box, where it is crushed into smaller particles. The crushed material then enters the screening and filtration box, where impurities and metal ions are removed. The material that has undergone preliminary screening and filtration is then transported to a high-temperature recovery furnace for heating and recovery treatment. During the screening and filtration process, the precipitate generated falls into a sedimentation tank connected to the lower part of the screening and filtration box. The material in the sedimentation tank enters the chemical filtration box for further treatment, and the treated liquid is returned to the screening and filtration box through a circulation pipe to continue participating in the screening and filtration process.

[0008] Preferably, two sets of water pumps are symmetrically installed on the outside of the circulation pipe, and two sets of filter tanks are linearly opened on the upper side of the side where the sedimentation tank is installed in the screening and filtration box, and filter plates are slidably installed inside the filter tanks.

[0009] Preferably, a handle is provided through one end of the filter plate, a discharge plate is installed obliquely on the outside of the screening and filtering box, and a filter screen that only allows water to pass through is installed at the bottom of the discharge plate. A waste sedimentation collection tank is provided inside the sedimentation tank.

[0010] Preferably, a drive belt is installed inside the mounting platform, baffles are installed on both sides of the top of the mounting platform, a drive motor is installed outside the mounting platform, the output end of the drive motor is connected to the drive shaft inside the drive belt, and multiple sets of primary support columns are symmetrically and linearly installed at the bottom of the mounting platform, with a primary fixing plate installed at the bottom of each primary support column.

[0012] Preferably, two sets of couplings are linearly installed on the outside of the crushing box. A crushing motor is installed on one side of the coupling.

A secondary support column is installed at the center of the bottom of the crushing box, and a secondary fixing plate is installed at the bottom of the secondary support column.

[0013] Preferably, the high-temperature recovery furnace is hollow, with a heating plate embedded in a ring inside. A discharge pipe is installed outside the high-temperature recovery furnace, and a discharge valve is installed between the discharge pipe and the high-temperature recovery furnace. An exhaust pipe is installed at the center of the top of the high-temperature recovery furnace.

[0014] The beneficial effects of this utility model are as follows: Through a series of processes such as crushing, screening and filtration, and high-temperature recovery, the valuable components in electrolytic manganese slag are fully recovered, improving resource utilization. A complete water circulation path is constructed, allowing the water used in screening and washing to be treated by sedimentation and chemical filtration before returning to the screening and filtration box for recycling. This effectively reduces the introduction of fresh water resources, lowers water resource losses, and meets the requirements of sustainable development. Compared with the unidirectional water use mode of most existing equipment, which results in serious water waste, this solution greatly reduces unnecessary water loss through a recycling system. It solves the problem of unidirectional water consumption and non-recyclability of water resources in existing electrolytic manganese slag recycling equipment, which leads to resource waste.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of an electrolytic manganese slag recovery device, comprising an installation platform 1, a feed hopper 2, a crushing box 3, a screening and filtering box 4, and a high-temperature recovery furnace 5. The top of the installation platform 1 is equipped with a feed hopper 2 for feeding materials into the device. One end of the installation platform 1 is equipped with a crushing box 3 for crushing materials. A screening and filtering box 4 for removing impurities and metal ions is connected to one side of the crushing box 3. A high-temperature recovery furnace 5 for heating and recovering materials is connected to one side of the screening and filtering box 4. A sedimentation tank 405 is connected to the lower part of the outside of the screening and filtering box 4. One end of the sedimentation tank 405 is connected to a chemical filter box 406. The top of the chemical filter box 406 is connected to a circulation pipe 407. The other end of the circulation pipe 407... Connected to the screening and filtration box 4, when the electrolytic manganese slag recovery equipment is working, the electrolytic manganese slag first enters the device through the feed hopper 2, and then the material enters the crushing box 3, where it is crushed into smaller particles. The crushed material then enters the screening and filtration box 4, where impurities and metal ions are removed. The material that has undergone preliminary screening and filtration is then transported to the high-temperature recovery furnace 5 for heating and recovery treatment. During the screening and filtration process, the precipitate generated falls into the sedimentation tank 405 connected to the lower part of the screening and filtration box 4. The substances in the sedimentation tank 405 enter the chemical filtration box 406 for further treatment. The treated liquid is returned to the screening and filtration box 4 through the circulation pipe 407 to continue participating in the screening and filtration process.

[0022] Please see Figure 4In this embodiment, two sets of water pumps 408 are symmetrically installed outside the circulation pipe 407. Two sets of filter tanks 401 are linearly opened on the upper side of the screening and filtration box 4, near the sedimentation tank 405. Filter plates 402 are slidably installed inside each filter tank 401. The two sets of water pumps 408 symmetrically installed outside the circulation pipe 407 provide strong power support for water circulation. During the operation of the electrolytic manganese slag recovery equipment, the water pumps 408 can quickly and stably transport the water treated by the chemical filter box 406 back to the screening and filtration box 4. Compared with natural gravity circulation, this greatly improves the water circulation speed, ensuring that there is always sufficient and fresh water in the screening and filtration box 4 for the screening and filtration of manganese slag. This guarantees the efficient and continuous operation of the entire recovery process. Stable water circulation helps maintain a stable filtration environment within the screening and filtration box 4. The rapid water flow can promptly remove impurities and fine particles generated during the filtration process, preventing their accumulation in the filtration area, thereby improving the working efficiency of the filtration device and extending its service life. Simultaneously, it also enhances the screening and filtration box 4's ability to effectively filter manganese slag. The screening and filtration effects are more uniform and stable, which is beneficial to improving the quality of recycled products. A handle 403 is provided through one end of the filter plate 402. A discharge plate 404 is obliquely installed on the outside of the screening and filtration box 4. A filter screen that only allows water to pass through is installed at the bottom of each discharge plate 404. A waste sedimentation collection tank is provided inside the sedimentation tank 405. The handle 403 through one end of the filter plate 402 provides a direct and convenient point of force for the operator. When it is necessary to install, disassemble, clean, or replace the filter plate 402, the operator... Operators can easily grasp the handle 403 and perform pushing and pulling actions. Compared with the filter plate 402 without the handle 403, this greatly reduces the difficulty of operation, saves operation time, and improves work efficiency. The discharge plate 404 installed obliquely on the outside of the screening and filtering box 4 can effectively guide the manganese slag after screening and filtration to be discharged smoothly from the screening and filtering box 4. The oblique design utilizes the effect of gravity, allowing the manganese slag to slide naturally along the discharge plate 404, reducing the material residue in the screening and filtering box 4 and improving the material output efficiency.

[0023] Please see Figures 1-3In this embodiment, a transmission belt 102 is installed inside the mounting platform 1, and baffles 101 are installed on both sides of the top of the mounting platform 1. A transmission motor 105 is installed outside the mounting platform 1, and the output end of the transmission motor 105 is connected to the transmission shaft inside the transmission belt 102. Multiple sets of primary support columns 103 are symmetrically and linearly installed at the bottom of the mounting platform 1, and each primary support column 103 has a primary fixing plate 104 installed at its bottom. The transmission belt 102 installed inside the mounting platform 1 is connected to the external transmission motor 105. The output end of the transmission motor 105 drives the transmission shaft inside the transmission belt 102, thereby driving the transmission belt 102 to rotate. This design realizes efficient material transfer between different processing stages of the equipment. The baffles 101 installed on both sides of the top of the mounting platform 1 can effectively prevent electrolytic manganese slag from falling off the transmission belt 102 during material transfer. The crushing box 3 is hollow, and the internal structure of the crushing box 3 is rectangular. There are multiple sets of rotating shafts 303, and multiple sets of rotating rings 304 are sleeved on the outside of the rotating shafts 303. Multiple sets of crushing columns 306 are installed on the outside of the rotating rings 304. The discharge port 305 is opened through the outside of the crushing box 3. The multiple sets of rotating shafts 303 arranged in a rectangular shape inside the crushing box 3, together with the multiple sets of rotating rings 304 and the crushing columns 306 on the rotating rings 304, form a high-efficiency crushing system. When the rotating shafts 303 rotate, they drive the rotating rings 304 and the crushing columns 306 to move synchronously. Since the rotating shafts 303 are rectangularly distributed, the crushing columns 306 at different positions can hit and crush the electrolytic manganese slag entering the crushing box 3 from multiple angles. The arrangement of multiple sets of rotating rings 304 and crushing columns 306 increases the contact area and crushing points with the manganese slag. When the equipment is running, a large number of crushing columns 306 act on the manganese slag at the same time, which can generate greater crushing force and effectively crush some hard manganese slag.

[0024] Please see Figures 2-3In this embodiment, two sets of couplings 301 are linearly installed on the outside of the crushing box 3. A crushing motor 302 is installed near one edge of the coupling 301. The output ends of the two sets of crushing motors 302 are connected to multiple sets of rotating shafts 303 through the two sets of couplings 301. A secondary support column 307 is installed at the center of the bottom of the crushing box 3. A secondary fixing plate 308 is installed at the bottom of the secondary support column 307. When the crushing box 3 is working, the crushing column 306 inside strongly impacts and crushes the manganese slag, which will generate violent vibration. The secondary support column 307 is installed at the center of the bottom of the crushing box 3. Together with the secondary fixing plate 308 at the bottom, it provides an additional stable support point for the crushing box 3. The high-temperature recovery furnace 5 is hollow. A heating plate is embedded in the ring inside the high-temperature recovery furnace 5. A discharge pipe 503 is installed on the outside of the high-temperature recovery furnace 5. A discharge valve 501 is installed between the discharge pipe 503 and the high-temperature recovery furnace 5. The high-temperature recovery furnace 5 has an exhaust pipe 502 connected to the center of its top. The heating plate embedded in the ring inside the high-temperature recovery furnace 5 can form a uniform high-temperature environment inside the furnace. The ring design makes the heating area larger and the coverage wider, so that the electrolytic manganese slag can be heated in all directions inside the furnace. Whether the manganese slag is located in the center of the furnace or near the furnace wall, it can be fully and evenly heated, effectively avoiding local overheating or underheating. This not only improves the pyrolysis efficiency, but also ensures that the valuable components in the manganese slag are fully decomposed and recovered, thereby improving the resource recovery rate. The discharge valve 501 installed between the discharge pipe 503 and the high-temperature recovery furnace 5 provides a flexible control method for the discharge of the pyrolysis products. During the operation of the high-temperature recovery furnace 5, the discharge amount and discharge speed can be precisely controlled by controlling the opening degree and time of the discharge valve 501 according to actual production needs, such as the operating status of subsequent processing equipment and the material accumulation.

[0025] During operation, the electrolytic manganese slag to be recycled enters the equipment through the feed hopper 2, which is installed at the top of the mounting platform 1 to provide an entry channel for the manganese slag. Inside the mounting platform 1, the transmission belt 102, driven by the transmission motor 105, transports the manganese slag from the feed hopper 2 to the crushing box 3. Baffles 101 on both sides of the transmission belt 102 prevent the manganese slag from scattering during transport. In the crushing box 3, two sets of crushing motors 302 drive multiple sets of rotating shafts 303 to rotate at high speed via a coupling 301. The rotating shafts 303 drive the externally fitted rotating ring 304 and the crushing columns 306 on the rotating ring 304 to... The manganese slag is subjected to multi-angle and all-round impact and crushing to break large pieces into smaller particles. The crushed manganese slag is discharged from the crushing box 3 through the discharge port 305. The manganese slag discharged from the crushing box 3 enters the screening and filtering box 4. In the two sets of filter tanks 401 on the upper side of the screening and filtering box 4, the sliding filter plates 402 filter the manganese slag to remove impurities and some metal ions. During this process, the filter plates 402 can be slid out of the filter tanks 401 by the handles 403 for cleaning or replacement as needed. The manganese slag that has undergone preliminary filtration continues to be processed in the screening and filtering box 4. Further processing involves the wastewater generated during the treatment of manganese slag in the screening filter box 4 flowing into the sedimentation tank 405 from the lower part of the screening filter box 4. In the sedimentation tank 405, gravity causes the solid particles in the wastewater to settle into the waste sedimentation collection tank. The supernatant after sedimentation flows from one end of the sedimentation tank 405 into the chemical filter box 406. The chemical filter box 406 further removes residual impurities and metal ions in the water by adding chemical agents. The water treated by the chemical filter box 406 is then pumped by two sets of water pumps 408 symmetrically installed outside the circulation pipe 407. The ring pipe 407 returns to the screening and filtration box 4 to realize water recycling and reduce water waste. After screening and filtration, the manganese slag enters the high-temperature recovery furnace 5. The heating plate embedded in the ring inside the high-temperature recovery furnace 5 heats the manganese slag evenly, so that the valuable components in the manganese slag decompose at high temperature. The waste gas generated during the pyrolysis process is discharged through the exhaust pipe 502 at the top center and guided to the subsequent waste gas treatment system. The pyrolysis product is discharged through the discharge pipe 503. The discharge valve 501 can control the discharge amount and discharge speed according to the actual production needs to ensure the smooth operation of the entire recovery process.

[0026] Through the above steps, when the electrolytic manganese slag recovery equipment is working, the electrolytic manganese slag first enters the device through the feed hopper 2, and then the material enters the crushing box 3, where it is crushed into smaller particles. The crushed material then enters the screening and filtration box 4, where impurities and metal ions are removed. The material that has undergone preliminary screening and filtration is then transported to the high-temperature recovery furnace 5 for heating and recovery treatment. During the screening and filtration process, the precipitate generated falls into the sedimentation tank 405 connected to the lower part of the screening and filtration box 4. The substances in the sedimentation tank 405 enter the chemical filtration box 406 for further treatment. The treated liquid is returned to the screening and filtration box 4 through the circulation pipe 407 to continue participating in the screening and filtration process.
