Description

Technical Field

[0001] This invention relates to the field of environmentally friendly mining wastewater treatment technology, specifically to an environmentally friendly mining wastewater purification and treatment device. Background Technology

[0002] The mining industry generates a large amount of mining wastewater during mineral extraction and beneficiation. This wastewater contains a large number of solid impurities, and direct discharge would seriously pollute the surrounding soil and aquatic ecosystems. Therefore, it must be purified to meet standards before it can be discharged or reused. Currently, filtration is the mainstream process for purifying mining wastewater. It achieves preliminary purification by intercepting solid impurities in the wastewater through filter screens, and related filtration equipment is widely used in the industry.

[0003] However, existing mining wastewater treatment equipment generally suffers from a key technical problem: filter maintenance requires system shutdown, leading to a significant decrease in wastewater treatment efficiency. Mining wastewater contains high levels of impurities and has a complex composition. During continuous filtration, impurities quickly accumulate on the filter surface, causing clogging. This not only reduces the filtration rate but also affects the filtration effect. To ensure purification quality, the filter needs to be cleaned or replaced regularly. However, existing equipment often has fixed filter installations, requiring maintenance to stop wastewater transport and filtration operations, disassemble the filter for cleaning or replacement, and then restart the equipment.

[0004] Mining operations are highly continuous, and downtime for wastewater treatment equipment directly interrupts the wastewater treatment process, leading to wastewater accumulation. This not only fails to meet real-time environmental discharge requirements but also slows down mining production. Especially for large mines, the daily wastewater volume is enormous; every hour of downtime for maintenance results in a significant amount of wastewater remaining untreated, increasing environmental risks and production losses. Therefore, how to solve the problem of downtime for filter maintenance and achieve filter maintenance without shutdown, ensuring the continuity and efficiency of mining wastewater purification, has become a core technical challenge urgently needing to be addressed in the field of mining wastewater treatment equipment. Summary of the Invention

[0005] The purpose of this invention is to provide an environmentally friendly mining wastewater purification and treatment equipment to solve the core technical problem that existing mining wastewater purification equipment requires shutdown for filter maintenance, resulting in low wastewater treatment efficiency and inability to meet the continuous mining operation requirements.

[0009] Preferably, in the two arc-shaped filter screens, the arc-shaped filter screen at the higher position is provided with an arc-shaped nozzle on its outer side. The arc-shaped nozzle has multiple spray holes on its arc surface facing the arc-shaped filter screen. A connecting pipe is fixedly installed on the delivery pipe, and a valve is fixedly installed on the connecting pipe. A filter head is fixedly installed at the top of the connecting pipe, and a filter plate is fixedly installed on the inner surface of the filter head. A main pipe is fixedly installed at the water outlet end of the filter head, and the main pipe is connected to the interior of the arc-shaped nozzle through multiple branch pipes.

[0010] Preferably, a drain pipe is fixedly installed on the filter head, and a cover is threaded onto the bottom end of the drain pipe.

[0011] Preferably, arc-shaped connecting strips are fixedly installed at both ends of the arc-shaped filter screen in the width direction, and mounting rings are fixedly installed on both sides of the annular processing frame. The mounting rings and the arc-shaped connecting strips are fixedly connected by multiple bolts and nuts.

[0012] Preferably, the annular processing frame includes a first side ring, a second side ring, and a fourth side ring; The second side ring and the fourth side ring are located on the same side, and the second side ring and the fourth side ring are fixedly connected by a plurality of first U-shaped frames; the fourth side ring is fixedly connected to the first side ring by a plurality of second U-shaped frames, and a second U-shaped frame is provided at the end of each arc-shaped filter screen.

[0013] Preferably, the support frame includes a fixed rod, a connecting ring, a connecting frame, and a support rod; The support rods are provided in pairs, and both support rods are fixedly installed on the top of the narrow body pool.

This, combined with an electric telescopic rod, adjusts the opening and closing of the opening and the orientation of the push plate. During maintenance, the lower filter continuously filters mining wastewater without interrupting wastewater transport. This effectively solves the problem of wastewater accumulation caused by maintenance downtime in traditional equipment, adapts to the continuous operation requirements of mining, and reduces environmental risks.

The branch pipe diversion design ensures that mining wastewater enters the treatment chamber evenly, avoiding localized wear on the filter screen; the push plate edge fits tightly against the inner wall of the chamber, and the guide design at the opening effectively pushes impurities out. Arc-shaped nozzles and other components work in conjunction with the rotating filter screen to achieve thorough rinsing, reducing impurity residue and clogging, extending the filter screen's lifespan, and ensuring long-term, high-efficiency purification. 3. Through the synergistic effect of high-efficiency filtration, thorough impurity removal, and rinsing of the arc-shaped filter screen, the equipment can significantly improve the compliance rate of mining wastewater purification, preventing the direct discharge of wastewater containing large amounts of solid impurities and thus avoiding soil and water pollution. Simultaneously, the non-stop maintenance mode reduces the risk of wastewater accumulation and overflow, and the detachable filter screen design facilitates regular deep cleaning, ensuring stable purification effects and helping mining operations achieve green and environmentally friendly production, in line with ecological protection requirements.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] This embodiment discloses an environmentally friendly mining wastewater purification and treatment equipment, used for the efficient purification of mining wastewater, solving problems such as uneven filtration, inconvenient filter maintenance, and incomplete impurity removal in existing equipment. The following provides a detailed description of the equipment in conjunction with its specific structural connections and working process.

[0031] This equipment includes a purification tank and a narrow-body tank 1, which are connected to each other. The treated mining wastewater can flow from the narrow-body tank 1 into the purification tank for further advanced treatment. The top of the narrow-body tank 1 is equipped with a conveying pipe 23, which serves as the conveying channel for the mining wastewater.

[0032] A ring-shaped treatment frame is mounted on the top of the narrow-body pool 1 via a support frame. The support frame provides stable support for the ring-shaped treatment frame and is specifically composed of a pair of support rods 22, a fixing rod 16, a connecting ring 17, and a connecting frame 21. The two support rods 22 are fixed parallel to each other on the top of the narrow-body pool 1. The two ends of the fixing rod 16 are fixedly connected to the two support rods 22 respectively along its length, forming a transverse support frame. The connecting ring 17 is rotatably engaged with the ring-shaped treatment frame, and the fixing rod 16 is fixedly connected to the connecting ring 17 through the connecting frame 21. Through this structural design, a stable support for the ring-shaped treatment frame can be achieved without interfering with the rotation and adjustment of the ring-shaped treatment frame.

[0033] A rotating ring 7 is rotatably installed on the inner side of the annular treatment frame. Multiple conveying branch pipes 24 are fixedly connected to one end of the conveying pipe 23. The outlet ends of the multiple conveying branch pipes 24 are all fixedly connected to the rotating ring 7. Through the diversion effect of the multiple conveying branch pipes 24, the mining wastewater flowing into the subsequent treatment structure can be evenly distributed, avoiding uneven filtration caused by concentrated wastewater impacting a single area. This ensures that the mining wastewater conveyed by the conveying pipe 23 can be accurately introduced into the interior of the annular treatment frame through the rotating ring 7. An annular filter screen frame is installed on the outer side of the annular treatment frame. The two together form an annular treatment chamber, which is the core filtration area for the mining wastewater and also serves to temporarily store impurities generated during filtration. A pair of openings are provided on the annular filter screen frame, located on the outer side of the top of the narrow-body pool 1.

[0034] The annular treatment frame consists of a pair of arc-shaped filter screens 9 and a pair of arc-shaped plates 25. Both arc-shaped filter screens 9 can be detachably installed on the annular treatment frame, and an arc-shaped plate 25 is correspondingly provided at both ends of the length direction of the two arc-shaped filter screens 9. Arc-shaped connecting strips 10 are fixed to both ends of the width direction of the arc-shaped filter screens 9. Mounting rings 8 are fixed to both sides of the annular treatment frame. The mounting rings 8 and the arc-shaped connecting strips 10 are fixedly connected by multiple bolts 28 and nuts 29. By removing the bolts 28 and nuts 29, the arc-shaped filter screens 9 can be easily disassembled and replaced, reducing maintenance difficulty.

[0035] Each arc-shaped plate 25 is fixedly connected to the annular processing frame via an electric telescopic rod 26. The telescopic movement of the electric telescopic rod 26 directly drives the arc-shaped plate 25 to translate, thereby opening and closing the corresponding opening on the annular filter frame. Arc-shaped strips 27 are fixed at both ends of the arc-shaped plate 25 in the width direction. Sealing gaskets are fitted on the surface of the arc-shaped strips 27 facing the mounting ring 8. When the electric telescopic rod 26 drives the arc-shaped plate 25 to close the opening, the sealing gaskets can tightly fit against the mounting ring 8, ensuring the sealing of the annular processing chamber and preventing mining wastewater from leaking from the opening during the filtration process.

[0036] A second motor 19 is fixedly mounted on the support rod 22. A second gear 20 is fixedly mounted on the output end of the second motor 19. A second gear ring 18 is fixedly mounted on the ring processing frame. The second gear ring 18 and the second gear 20 are in a meshing state. When the second motor 19 starts, its output end drives the second gear 20 to rotate. Through the meshing transmission between the second gear 20 and the second gear ring 18, the entire ring processing frame can be driven to rotate around its central axis.

[0037] A rotating ring 12 is rotatably mounted on the annular processing frame. A push plate 11 is fixedly mounted on one side of the rotating ring 12. The push plate 11 is correspondingly positioned inside the annular processing cavity, and the edge of the push plate 11 is in close contact with the inner surface of the annular processing frame and the annular filter frame. A drive assembly is mounted on the support frame to provide power for the rotation of the rotating ring 12. This drive assembly consists of a first toothed ring 13, a first motor 14, and a first gear 15. The first toothed ring 13 is fixedly connected to the rotating ring 12, the first motor 14 is fixedly mounted on the support rod 22, and the first gear 15 is fixedly mounted on the output end of the first motor 14. The first toothed ring 13 and the first gear 15 are in a meshed state. When the first motor 14 starts, it drives the first gear 15 to rotate. Through the meshing transmission between the first gear 15 and the first toothed ring 13, the rotating ring 12 can be driven to rotate synchronously, thereby driving the push plate 11 to make circular motion within the annular processing cavity.

[0038] To achieve online cleaning of the arc-shaped filter screen 9, this equipment is also equipped with an arc-shaped nozzle 30, a connecting pipe 35, a filter head 31, a filter plate 32, a main pipe 33, and multiple branch pipes 34. The arc-shaped nozzle 30 is positioned on the outer side of the arc-shaped filter screen 9 that is higher in the two arc-shaped filter screens 9. Multiple spray holes are evenly distributed on the arc surface of the arc-shaped filter screen 9, enabling comprehensive cleaning and rinsing of the entire surface of the arc-shaped filter screen 9.

[0039] A connecting pipe 35 is fixedly installed on the conveying pipe 23. A valve 36 is fitted on the connecting pipe 35 to control its opening and closing. A filter head 31 is fixedly installed at the top of the connecting pipe 35. A filter plate 32 is fixedly installed on the inner surface of the filter head 31. The filter plate 32 is used to filter the mining wastewater entering the filter head 31, removing large particles to prevent clogging of subsequent pipes and spray holes. A main pipe 33 is fixedly installed at the outlet end of the filter head 31. The main pipe 33 is connected to the interior of the arc-shaped nozzle 30 through multiple branch pipes 34, forming a complete flushing water flow channel. In addition, a drain pipe 37 is fixedly installed on the filter head 31. A cover 38 is threaded onto the bottom end of the drain pipe 37. When a large amount of impurities accumulate on the surface of the filter plate 32, the cover 38 can be removed, and the impurities inside the filter head 31 can be thoroughly removed through the drain pipe 37 to ensure smooth flushing water flow.

[0040] The specific structure of the annular processing frame includes a first side ring 2, a second side ring 3, and a fourth side ring 4. The second side ring 3 and the fourth side ring 4 are located on the same side and are fixedly connected by multiple first U-shaped brackets 5 to ensure the stability of the connection between them. The fourth side ring 4 is fixedly connected to the first side ring 2 by multiple second U-shaped brackets 6. The combination and assembly of the first side ring 2, second side ring 3, fourth side ring 4, first U-shaped brackets 5, and second U-shaped brackets 6 form a stable annular frame structure, providing a reliable foundation for the installation of components such as the annular filter screen frame and the rotating ring 12. Each arc-shaped filter screen 9 has a corresponding second U-shaped bracket 6 at its end, which limits the end position of the arc-shaped filter screen 9. When installing the arc-shaped filter screen 9, both ends of the arc-shaped filter screen 9 can be supported on the two second U-shaped brackets 6, and then the mounting ring 8 and the arc-shaped connecting strip 10 are fixedly connected by bolts 28 and nuts 29.

[0041] Processing flow: Phase 1: First, the conveying switch of the conveying pipe 23 is turned on. The mining wastewater is diverted through the conveying pipe 23 to multiple conveying branch pipes 24, and then evenly conveyed to the rotating ring 7. From there, it is guided into the annular treatment frame and finally flows into the annular treatment chamber. Inside the annular treatment chamber, the mining wastewater permeates outward through the annular filter frame. The annular filter frame intercepts large particulate impurities in the wastewater, which are blocked on the inner surface of the frame. The filtered wastewater falls into the narrow-body pool 1 and then flows into the purification pool for further deep treatment.

[0042] Phase Two: Impurity Removal. As the filtration process continues, impurities gradually accumulate on the inner surface of the annular filter frame. When the accumulation reaches a level that affects filtration efficiency, the first motor 14 of the drive assembly is activated. The first motor 14 drives the first gear 15 to rotate. Through the meshing transmission between the first gear 15 and the first gear ring 13, the rotating ring 12 is driven to rotate. The push plate 11 moves synchronously within the annular processing chamber along with the rotating ring 12. Because the edge of the push plate 11 is in close contact with the annular processing frame and the inner surface of the annular filter frame, it can effectively push the impurities within the annular processing chamber to move synchronously during the movement.

[0043] During the rotation of the push plate 11, the first opening it passes through is closed by the arc plate 25. When the push plate 11 rotates one revolution and moves to the second opening, the push plate 11 is tilted downward. Under the pushing force of the push plate 11 and its own gravity, the impurities are discharged from this opening into the collection device on the outside of the top of the narrow body pool 1, thus completing the impurity cleaning.

[0044] When only different arc-shaped filter screens 9 need to be replaced to filter mining wastewater, the second motor 19 is started to drive the ring treatment frame to rotate 180°, so that the two arc-shaped filter screens 9 are swapped to ensure the filtration efficiency of mining wastewater.

[0045] Phase 3: Flushing and Maintenance of the Arc-Shaped Filter Screen. When residual impurities that are difficult to remove through the impurity cleaning process adhere to the surface of the arc-shaped filter screen 9, the online flushing and maintenance process is initiated. First, the electric telescopic rod 26 at the corresponding opening is retracted, and the opening is closed by the arc-shaped plate 25 to ensure the sealing of the annular treatment chamber. Then, the second motor 19 is started, which drives the second gear 20 to rotate. Through the meshing transmission between the second gear 20 and the second gear ring 18, the annular treatment frame is driven to rotate, rotating the arc-shaped filter screen 9 to be cleaned to a higher position, so that the arc-shaped filter screen 9 is aligned with the arc-shaped nozzle 30. Next, the valve 36 on the connecting pipe 35 is opened, and part of the mining wastewater in the conveying pipe 23 is discharged through the connecting pipe 35. Pipe 35 enters the filter head 31, and after being filtered by the filter plate 32 to remove large particles of impurities, it flows into the main pipe 33, and then is distributed through multiple branch pipes 34 to the interior of the arc-shaped nozzle 30. Finally, the wastewater is sprayed through multiple spray holes on the arc-shaped nozzle 30 onto the outer surface of the arc-shaped filter screen 9 that needs to be cleaned. At the same time, the second motor 19 is controlled to drive the annular processing frame to move repeatedly within a certain angle, causing the arc-shaped filter screen 9 to rotate synchronously, so that the arc-shaped nozzle 30 can thoroughly rinse the entire arc surface of the arc-shaped filter screen 9. The impurities washed off fall into the annular processing chamber. After rinsing is completed, valve 36 is closed, and the impurities generated during rinsing can be discharged through the impurity cleaning process. If there are many impurities on the surface of the filter plate 32, the cover 38 at the bottom of the drain pipe 37 can be removed, and the impurities in the filter head 31 can be removed through the drain pipe 37. After cleaning, the cover 38 can be tightened again. Throughout the entire flushing and maintenance process, the conveying pipe 23 continuously delivers mining wastewater to the annular treatment chamber, while the unflushed arc-shaped filter screen 9 on the other side continues to filter, achieving non-stop maintenance and ensuring uninterrupted mining wastewater treatment efficiency.
