Description

Technical Field

[0001] This utility model relates to the field of microbial treatment technology, and in particular to a manganese slag treatment device that facilitates sludge removal. Background Technology

[0002] Manganese slag is a solid waste generated during the production of metallic manganese, primarily from electrolytic or metallurgical manganese processes. For every ton of metallic manganese produced, approximately 8-12 tons of manganese slag are generated. The hazards of manganese slag mainly include: leachate from stockpiles polluting soil and groundwater; potential accumulation of heavy metals through the food chain; ineffective recovery of manganese-containing minerals leading to resource loss; and the need for extensive land use and seepage prevention measures when using traditional landfill or stockpiling methods. Therefore, it is necessary to treat the manganese slag remaining after production to reduce its environmental harm.

[0003] In existing technologies, during the microbial treatment of manganese slag, manganese slag treatment devices often use a single filter layer (such as stainless steel filter screen or sand and gravel filter media) to filter the microbial treatment solution. However, the fine particles in the manganese slag and the precipitates formed by microbial metabolites (such as biofilms and extracellular polymers) easily adhere to the inner wall of the manganese slag treatment device. To clean these precipitates, the manganese slag treatment device needs to be shut down and disassembled for cleaning, which not only reduces the working efficiency of the manganese slag treatment device, but also increases the workload of technicians. Utility Model Content

[0004] The main objective of this invention is to provide a manganese slag treatment device that facilitates sludge removal, thereby solving the technical problem that the sediment adhering to the inner wall of the manganese slag treatment device is difficult to clean in the prior art.

[0005] To achieve the above objectives, this utility model provides a manganese slag treatment device that facilitates sludge removal, including a first container, a rotary drive assembly, a sludge removal assembly, and a first filter structure. The sludge removal assembly and the first filter structure are both disposed inside the first container. The first filter structure is fixed to the bottom of the first container. The first container is provided with a first sludge removal port that can be opened and closed. The bottom of the first sludge removal port is flush with the upper surface of the first filter structure.

[0006] The sludge removal component is connected to the rotary drive component. The sludge removal component includes a scraper, which is parallel to the inner wall of the first container. The scraping surface of the scraper abuts against the inner wall of the first container, and the lower end of the scraper is slidably connected to the upper surface of the first filter structure.

[0007] Preferably, the scraper is inclined inside the first container, with the upper end of the scraper inclined in the direction of rotation.

[0008] More preferably, the rotary drive assembly includes a rotating shaft, and multiple scrapers are provided. The rotating shaft is located at the axis of the first container. The upper end of the rotating shaft is rotatably connected to the first container, and the lower end of the rotating shaft is rotatably connected to the first filter structure. The multiple scrapers are distributed at equal intervals on the inner wall of the first container in a symmetrical manner with respect to the rotating shaft, and the scrapers are fixedly connected to the rotating shaft.

[0009] More preferably, the dredging assembly includes multiple connecting plates distributed along the scraper, one end of the connecting plate being fixedly connected to the scraper, the other end of the connecting plate being fixedly connected to the rotating shaft, and the surface of the connecting plate being perpendicular to the rotation direction of the rotating shaft.

[0010] Furthermore, the first container includes an inlet pipe, an outlet pipe, a first valve, and a second valve. A liquid collection chamber is formed between the first filter structure and the bottom plate of the first container. The inlet pipe communicates with the first container from the top and is connected to the first valve. The outlet pipe communicates with the liquid collection chamber from the bottom plate of the first container and is connected to the second valve.

[0011] Furthermore, it also includes a second container and a second filtration structure. The second container includes an inlet and an outlet. The inlet is connected to the first container, and the second filtration structure is connected between the inlet and the outlet for secondary filtration.

[0012] More preferably, the second filter structure includes a plurality of filter plates arranged parallel to each other inside the second container, wherein the pore size of the filter plate closer to the first container is larger than that of the filter plate on the other side.

[0013] More preferably, the second container further includes a second sludge removal port and a second opening and closing door, the second opening and closing door closing the second sludge removal port, the height of the second sludge removal port being the same as the height of the plurality of filter plates, and the plurality of filter plates being slidably connected to the second container through the second sludge removal port.

[0014] Preferably, the first container is further provided with an observation window, which extends through the side wall of the first container and is sealed with glass.

[0015] Preferably, the container further includes a plurality of support feet and an anti-slip pad for supporting the first container. The plurality of support feet are symmetrically distributed at equal intervals around a central axis at the bottom of the first container. The support feet are fixedly connected to the first container, and the anti-slip pad is fixed to the bottom of the support feet.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention uses a rotary drive assembly to rotate the sludge removal assembly. Because the scraping surface of the scraper of the sludge removal assembly abuts against the inner wall of the first container, the scraper not only scrapes off the sediment adhering to the inner wall of the first container during rotation, but also agitates the microbial treatment solution to ensure thorough mixing of the manganese slag with the solution. After the sediment falls, it accumulates on the first filter structure. After work, technicians open the first sludge removal port to clean the sediment from the first filter structure, thus significantly improving the working efficiency of the manganese slag treatment device and reducing the workload of technicians.

[0030] Please see Figures 1 to 3 This embodiment provides a manganese slag treatment device that facilitates sludge removal, including a first container 1, a rotary drive assembly 5, a sludge removal assembly, and a first filter structure 9. The sludge removal assembly and the first filter structure 9 are both disposed inside the first container 1. The first filter structure 9 is fixed to the bottom of the first container 1. The first container 1 is provided with a first sludge removal port that can be opened and closed. The bottom of the first sludge removal port is flush with the upper surface of the first filter structure 9. The sludge removal assembly is connected to the rotary drive assembly 5. The sludge removal assembly includes a scraper 8. The scraper 8 is parallel to the inner wall of the first container 1. The scraping surface of the scraper 8 abuts against the inner wall of the first container 1. The lower end of the scraper 8 is slidably connected to the upper surface of the first filter structure 9.

[0031] It is worth noting that the rotary drive component 5 in this embodiment uses a servo motor as an example, and the first opening / closing door 10 is used to close or open the first sludge removal port. In this embodiment, the sludge removal component is driven to rotate by a servo motor. Since the scraping surface of the scraper 8 of the sludge removal component abuts against the inner wall of the first container 1, the scraper 8 can not only scrape off the sediment attached to the inner wall of the first container 1 during rotation, preventing the material from adhering to the inner wall and causing clumping or corrosion, but also continuously clean the inner wall during stirring, reducing the frequency of manual cleaning. It can also stir the microbial treatment solution to ensure that the manganese slag is fully mixed with the solution. After the sediment falls, it accumulates on the first filter structure 9. After the technician finishes work, he / she opens the first opening / closing door 10 and cleans the sediment on the first filter structure 9 through the first sludge removal port, thereby significantly improving the working efficiency of the manganese slag treatment device and reducing the workload of the technician.

[0032] In this embodiment, preferably, the scraper 8 is inclined inside the first container 1, with its upper end inclined in the direction of rotation. The inclined scraper 8 automatically pushes the scraped-off sediment towards the first filter plate during rotation, facilitating sediment collection.

[0033] As a further preferred embodiment, the rotary drive assembly 5 includes a rotating shaft 6, and multiple scrapers 8 are provided. The rotating shaft 6 is located at the axis of the first container 1, with its upper end rotatably connected to the first container 1 and its lower end rotatably connected to the first filter structure 9. The multiple scrapers 8 are symmetrically distributed at equal intervals on the inner wall of the first container 1, and the scrapers 8 are fixedly connected to the rotating shaft 6. The rotary drive assembly 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the multiple scrapers 8 to simultaneously scrape away the sediment on the inner wall of the first container 1, which not only improves cleaning efficiency but also enhances stirring efficiency.

[0034] Please see Figure 4 In another embodiment, the dredging assembly includes multiple connecting plates 7 distributed along the scraper 8. One end of each connecting plate 7 is fixedly connected to the scraper 8, and the other end is fixedly connected to the rotating shaft 6. The surface of the connecting plate 7 is perpendicular to the rotation direction of the rotating shaft 6. During rotation, the connecting plate 7 has a larger contact area with the microbial treatment solution, allowing the manganese slag to fully contact the microorganisms, accelerating the degradation reaction, and further improving the stirring efficiency of the solution.

[0035] In this embodiment, the first container 1 further includes an inlet pipe 2, an outlet pipe 11, a first valve 3, and a second valve 12. A liquid collection chamber is formed between the first filter structure 9 and the bottom plate of the first container 1. The inlet pipe 2 connects to the first container 1 from the top and is connected to the first valve 3. The outlet pipe 11 connects to the liquid collection chamber from the bottom plate of the first container 1 and is connected to the second valve 12. The first valve 3 controls the amount of manganese slag input to avoid overloading or reaction imbalance caused by excessive feeding, prevents odor leakage or external pollutants from entering, and ensures a clean treatment environment. The second valve 12 controls the flow rate of the treated liquid into the second container 14 to avoid overload and, in conjunction with the first filter structure 9, reduces the risk of large particles entering the pipe.

[0036] Furthermore, it also includes a second container 14 and a second filter structure 16. The second container 14 includes an inlet and an outlet 17. The inlet is connected to the first container 1, and the second filter structure 16 is connected between the inlet and the outlet 17 for secondary filtration. The first container 1 and the second container 14 are connected in series by a connecting pipe 13 to form an integrated process from pretreatment to advanced treatment. The clear liquid treated in the second container 14 is discharged through the outlet 17, achieving final solid-liquid separation. Valves prevent liquid backflow, ensuring the unidirectional nature of the process, preventing liquid leakage or gas evaporation, and ensuring the environmental friendliness of the treatment process.

[0037] As a further preferred embodiment, the second filter structure 16 includes a plurality of filter plates arranged parallel to each other within the second container 14, wherein the pore size of the filter plate on the side closer to the first container 1 is larger than that of the filter plate on the other side.

[0038] Furthermore, the second container 14 also includes a second sludge removal port and a second opening / closing door 15. The second opening / closing door 15 closes the second sludge removal port. The height of the second sludge removal port is the same as the height of the plurality of filter plates. The plurality of filter plates are slidably connected to the second container 14 through the second sludge removal port. After the processing is completed, technicians can open the second opening / closing door 15, clean the sediment between the plurality of filter plates, and remove the filter plates from the second container 14 for cleaning or replacement.

[0039] In this embodiment, the first filter structure 9 intercepts large solid particles in the manganese slag, preventing them from entering subsequent processing stages, reducing the burden on subsequent filtration, and avoiding blockage of the discharge pipe 11 or damage to the second filter structure 16 by large impurities, thus achieving first-stage pretreatment. The second filter structure 16 further separates fine particles or microbial metabolites. The multi-layered structure formed by multiple filter plates can progressively intercept even finer particles, improving liquid clarity. The porous structure provides an attachment surface for microorganisms, enhancing biodegradation efficiency, thereby forming a multi-stage treatment structure and ultimately improving the manganese slag treatment effect. The second opening door 15 allows for quick replacement of aging or clogged filter plates, ensuring processing continuity. The second opening door 15 also allows for independent cleaning or replacement of internal components, enabling flexible maintenance.

[0040] Preferably, the first container 1 is further provided with an observation window 4, which extends through the side wall of the first container 1 and is sealed with glass. The observation window 4 allows for real-time observation of the liquid level, stirring status, and reaction process within the first container 1, facilitating timely adjustment of operating parameters (such as feed rate and stirring intensity). Abnormal phenomena (such as foam overflow or blockage) can be detected through the observation window 4, allowing for early intervention to prevent malfunctions.

[0041] Preferably, the device further includes a plurality of support feet 18 and an anti-slip pad 19 for supporting the first container 1. The plurality of support feet 18 are symmetrically distributed at equal intervals around the central axis at the bottom of the first container 1. The support feet 18 are fixedly connected to the first container 1. The anti-slip pad 19 is fixed to the bottom of the support feet 18 to ensure that the device is shock-resistant and tilt-resistant during operation. The bottom anti-slip pad 19 increases the friction force to prevent the equipment from shifting due to vibration or external force, thus ensuring safe production.

[0042] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
