Description

Technical Field

[0001] This invention belongs to the field of filtration equipment technology, and relates to an energy-saving filtration device and method for mining operations. Background Technology

[0002] Open-pit mines are a mining method that directly extracts mineral resources by stripping away the surface overburden. They are mainly used for mining shallow, large-scale ore bodies, such as coal, iron, and copper. They offer advantages such as high mining efficiency, low cost, high resource recovery rate, and ease of reclamation and remediation. However, the main disadvantage of open-pit mines is the accumulation of water within the mine due to atmospheric precipitation, groundwater infiltration, industrial water backflow, and enclosed terrain. This waterlogging can soak slopes, easily triggering geological disasters such as landslides and collapses, posing safety hazards during construction, and potentially flooding the working face, causing equipment malfunctions, mining interruptions, and impacting production efficiency. It also hinders subsequent reclamation efforts.

[0003] According to existing technologies, mine drainage generally uses the siphon principle to drain water from the mine. However, during the drainage process, the water contains a lot of broken ore and soil debris, which can easily clog the pipes. Chinese Patent Publication No. CN221933225U discloses an energy-saving filtration device for mining operations, comprising a shell, a cleaning device, and a crushing device. The cleaning device and the crushing device are fixedly installed. A lower support plate is provided on the top surface of the shell, a first fixing plate is provided on the inner wall above the lower support plate, and a second fixing plate is installed on the inner wall below the shell. The crushing device includes an underwater motor, which is installed on the bottom surface of the second fixing plate. The output shaft of the underwater motor passes through the second fixing plate and is fixedly installed at one end of the rotating shaft. This invention uses a cutting blade provided on the side wall of the rotating shaft above the scraper to crush and cut the sewage entering through the upper support plate and the crushed ore inside the sewage. Then, the inner and outer walls of the filter cylinder are scraped by the scraper inside the filter cylinder and the bottom scraper and side scraper outside the filter cylinder, avoiding blockage of the holes on the side wall and bottom of the filter cylinder, which would affect the normal use of the filter cylinder.

[0004] Compared to existing technologies that directly use water pumps to draw water, the above-mentioned device can reduce filter cartridge clogging through cutting blades, scrapers, bottom scrapers, and side scrapers. However, in actual use, gravel gradually accumulates inside the filter cartridge, making it difficult to drain promptly and completely through its pores, thus affecting long-term filtration efficiency. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an energy-saving filtration device and method for mining, so as to solve the technical problem in the prior art where crushed ore accumulates in the filter cartridge, affecting the filtration effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An energy-saving filtration device for mining operations includes: Filter holder, which includes connecting pipe; The spherical filter cartridge is rotatably connected to the filter frame, and the axis of rotation passes through the spherical shape of the filter cartridge and extends horizontally. Two inlets and outlets are opened through the side wall of the spherical filter cartridge, which are located on the same straight line and whose connection line is perpendicular to the axis of rotation of the spherical filter cartridge. The upper inlet and outlet are connected to the connecting pipe. The side wall of the spherical filter cartridge is also opened through multiple lateral water filtration holes. The partition plate assembly is circumferentially fixed to the inner wall of the spherical filter cylinder and has a through-hole with an intermediate filter hole that opens towards both inlet and outlet. The underwater motor's output end is connected to the spherical filter cartridge.

[0007] Furthermore, the partition plate assembly includes two partition plates, a fixed rod, and multiple arc-shaped rods. The two partition plates are arranged vertically at intervals and their circumferential edges are fixedly connected to the spherical filter cylinder. Both partition plates have multiple intermediate filter holes that pass through them. An inner channel is formed between the two partition plates, and the filter frame has an intermediate channel that connects to the inner channel. The two ends of the fixed rod are fixedly connected to the axial center of the two partition plates, respectively. Each arc-shaped rod is evenly distributed circumferentially, and its two ends are fixedly connected to the edge ends of the two partition plates, respectively.

[0008] Furthermore, each intermediate filter hole has a trumpet-shaped structure, and the opening size of each intermediate filter hole that is opened through the two partition plates is smaller when they face each other than when they face away.

[0009] Furthermore, both partition plates are conical in shape, with their conical ends extending towards each other and simultaneously fixedly connected to a fixing rod.

[0010] Furthermore, the filter frame also includes a vertically arranged support frame and a spherical frame whose lower end is fixedly connected to the upper end of the support frame. The support frame is provided with a lower channel that connects to the inlet and outlet opening downwards. The side wall of the spherical frame is formed through a middle channel that connects to each intermediate filter hole. The spherical filter cylinder is rotatably connected to the spherical frame, and its outer side abuts against the inner side of the spherical frame. The underwater motor is installed on the spherical frame, and the lower end of the connecting pipe is fixedly connected to the upper end of the spherical frame.

[0011] Furthermore, the spherical frame includes multiple circumferentially spaced arc rods distributed on the same spherical surface and a weft rod that is fixedly connected to each arc rod. The upper and lower ends of each arc rod are fixedly connected to the support frame and the connecting pipe, respectively, and a middle channel is formed between each arc rod. The inner sides of the weft rod and each arc rod abut against the outer side of the spherical filter cylinder. The underwater motor is fixedly installed on one of the arc rods.

[0012] Furthermore, one of the tubes is fixedly mounted with a protective cover via an arc rod, and the underwater motor is sealed and installed inside the protective cover.

[0013] Furthermore, the spherical filter cartridge includes two spherical plates with through-open structures at both ends. The ends of the two spherical plates with larger openings face each other and are circumferentially fixed to the edge ends of the two partition plates. The other ends of the two spherical plates with smaller openings form inlets and outlets, and multiple lateral water filtration holes are formed through-openings on the side walls of the two spherical plates.

[0014] Furthermore, the outer sides of both spherical plates abut against the inner side of the spherical frame.

[0015] Furthermore, it also includes a baffle, the edge of which is circumferentially fixed to the inside of the connecting pipe, and the baffle has multiple upper filter holes through it.

[0016] Furthermore, the pore diameter of the upper filter is smaller than that of the side filter pores and the middle filter pores.

[0017] Furthermore, the baffle has an arc-shaped plate structure, and the curved surface of its lower side coincides with the curved surface of the outer side of the spherical filter cartridge.

[0018] Furthermore, the upper filter hole has a trumpet-shaped structure with a smaller opening at the top and a larger opening at the bottom.

[0019] Furthermore, it also includes a protective frame, the upper end of which is fixedly connected to the connecting pipe, and the lower end extends downward and covers the outside of the spherical filter and the underwater motor, and the protective frame forms an external channel for water supply.

[0020] Furthermore, a battery is installed inside the protective cover to power the underwater motor; or An opening in the protective cover is sealed with wires to supply power to the underwater motor.

[0021] On the other hand, the present invention also provides an energy-saving filtration method for mining operations, comprising the following steps: S1. The above-mentioned mine energy-saving filtration device is hoisted to the bottom of the mine water accumulation, supported and fixed by the filter frame, and the upper end of the connecting pipe is connected to the water pump through the pipeline to the drainage point; S2. Start the water pump to allow the mine water to enter the spherical filter cartridge. After being filtered through the middle filter holes of the partition plate group and the side filter holes of the spherical filter cartridge, it is discharged through the connecting pipe. S3. During the filtration process, the water flowing into the inner channel flows downward to flush the middle filter holes of the lower partition plate, achieving self-cleaning. S4. After long-term use, start the underwater motor to drive the spherical filter cartridge to rotate 180°, so that the accumulated gravel on the partition plate assembly is discharged through the downward-opening inlet and outlet under the action of gravity.

[0022] Furthermore, in step S4, during the rotation process, the outer sides of the two spherical plates of the spherical filter cartridge abut against the inner sides of the weft rod and the longitudinal arc rod, thereby scraping and cleaning the lateral filter holes. The lateral filter holes are funnel-shaped structures with larger inward openings, which facilitates scraping in debris and discharging it inward.

[0023] Furthermore, it also includes step S5: during the discharge process, secondary filtration is performed through the upper filter holes of the baffle. The upper filter hole diameter is smaller than that of the side filter holes and the middle filter holes, and it is a funnel hole structure with a smaller opening at the top and a larger opening at the bottom. Furthermore, when the spherical filter cartridge rotates, the lower side of the baffle is scraped off on its outer side, clearing the blockage in the upper filter holes.

[0024] Furthermore, in step S1, a protective frame is used to cover the outside of the spherical filter cylinder and the underwater motor, forming secondary support and protection, and water flows in through the outer channel of the protective frame; The underwater motor is powered by a battery or sealed wires inside a protective cover, and its rotation only starts intermittently when buildup needs to be cleared, thus achieving energy saving.

[0025] The beneficial effects of this invention are as follows: The beneficial effects of this invention are as follows: 1. This mine utilizes an energy-saving filtration device with a spherical filter cartridge rotating and mounted on a filter frame. Accumulated water enters the spherical filter cartridge through a multi-stage filtration process involving downward-opening inlet and outlet ports, a funnel-shaped intermediate filter hole in a double-layer partition plate assembly, and side filter holes. The water is then extracted through a connecting pipe. During filtration, the water flowing into the inner channel washes down the lower partition plate, achieving dynamic self-cleaning. The lower partition plate effectively prevents bottom sludge from entering, significantly improving filtration stability and long-term efficiency, and completely solving the core problem in existing technologies where crushed ore accumulates inside the filter cartridge, causing blockage and affecting drainage.

[0026] 2. This invention uses an underwater motor to intermittently drive a spherical filter cartridge to rotate 180°. The gravel accumulated on the upper partition plate is automatically discharged through the downward-turning inlet and outlet under gravity. Simultaneously, the outer wall of the spherical filter cartridge tightly abuts against the arc and circular rods of the spherical frame, resulting in relative scraping and effectively removing debris adhering to the side walls, keeping the lateral filter holes unobstructed. The flared hole structure further promotes the inward shedding of debris, preventing clogging of the channels. This self-cleaning mechanism requires no manual intervention, reduces maintenance frequency, extends the continuous operation cycle of the equipment, and ensures efficient and stable mine drainage.

[0027] 3. This device incorporates an arc-shaped baffle and upper filter holes for secondary fine filtration, with a decreasing pore size design to prevent small particles from escaping. As the spherical filter cartridge rotates, it simultaneously scrapes the underside of the baffle, maintaining the upper filter holes' patency. A protective frame provides secondary support and external protection against damage from large rocks. The underwater motor only activates during cleaning, and combined with the low-resistance spherical structure and self-flushing water flow, it significantly reduces energy consumption and operating costs, achieving the goal of energy-saving and environmentally friendly mine waterlogging management.

[0034] Example 1 Please see Figure 1-5 This embodiment provides an energy-saving filtration device for mining operations, comprising: Filter frame 1, which includes connecting pipe 13; The spherical filter cartridge 2 is rotatably connected to the filter frame 1, and the axis of rotation passes through the center of the spherical filter cartridge 2 and extends in the horizontal direction. The side wall of the spherical filter cartridge 2 has two inlet and outlet 21 located on the same straight line and connected perpendicular to the axis of rotation of the spherical filter cartridge 2. The inlet and outlet 21 facing the opening are connected to the connecting pipe 13. The side wall of the spherical filter cartridge 2 also has multiple lateral water filtration holes 22. The partition plate assembly 3 is circumferentially fixed to the inner wall of the spherical filter cylinder 2 and has a through-hole 4 that opens towards both inlet and outlet 21. The underwater motor 5 has its output end connected to the spherical filter cartridge 2.

[0035] In use, the entire device is placed in the accumulated water in the mine. The lower end of the filter frame 1 is supported, and the upper end of the connecting pipe 13 is connected to the drainage point through the pipe and water pump. The accumulated water in the mine enters the spherical filter cylinder 2 through the downward-opening inlet and outlet 21, each intermediate filter hole 4, and each side filter hole 22. After being filtered, it is pumped out. During long-term use, the stones accumulated through the intermediate filter holes 4 and the side filter holes 22 accumulate on the partition plate group 3. After long-term use, the spherical filter cylinder 2 can be rotated 180° by starting the underwater motor 5, and the partition plate group 3 can be rotated 180°. Under the action of gravity, the accumulated stones are discharged downward through the downward-opening inlet and outlet 21, realizing the emptying of the stones accumulated in the spherical filter cylinder 2. This solves the technical problem in the prior art where crushed ore accumulates in the filter cylinder, affecting the filtration effect.

[0036] Please see Figure 3-5 In this embodiment: the partition plate group 3 includes two partition plates 31, a fixing rod 32 and multiple arc rods 33. The two partition plates 31 are distributed vertically at intervals and their circumferential edges are fixedly connected to the spherical filter cylinder 2. Both partition plates 31 are provided with multiple intermediate filter holes 4. An inner channel is formed between the two partition plates 31, and the filter frame 1 has an intermediate channel that connects to the inner channel. The two ends of the fixing rod 32 are respectively fixedly connected to the axial center of the two partition plates 31. Each arc rod 33 is evenly distributed circumferentially, and its two ends are respectively fixedly connected to the edge ends of the two partition plates 31.

[0037] By setting two spaced partition plates 31, when the device is hoisted into the mine, the lower partition plate 31 can form a barrier to prevent silt and other debris from the bottom of the mine from entering through the downward-opening inlet and outlet 21 and clogging the partition plate assembly 3, thus affecting the drainage effect. During the filtration process, water in the mine can enter the inner channel through the middle channel, and then be filtered upward through the various intermediate filter holes 4 of the upper partition plate 31 into the spherical filter cylinder 2, and discharged through the connecting pipe 13. At the same time, while filtering and draining, the water entering the inner channel can be flushed downward through the various intermediate filter holes 4 of the lower partition plate 31 under the action of water flow, thus cleaning the intermediate filter holes 4 and ensuring the subsequent water filtration effect.

[0038] Based on the above embodiments, the spherical filter cartridge 2 includes two spherical plates with through-open structures at both ends. The ends of the two spherical plates with larger openings face each other and are circumferentially fixed to the edge ends of the two partition plates 31. The other ends of the two spherical plates with smaller openings form inlet and outlet 21. Multiple lateral water filtration holes 22 are formed through-openings on the side walls of the two spherical plates.

[0039] Based on the above embodiments, the partition plate assembly 3 also includes two shafts 34 located on the same straight line. One end of each shaft 34 is fixedly connected to two arc-shaped rods 33, and the other end is rotatably connected to the filter frame 1, so as to realize the rotatable installation of the spherical filter cylinder 2 through the shafts 34.

[0040] In this embodiment, each intermediate filter hole 4 is a horn hole structure, and the opening size of each intermediate filter hole 4 that is opened through the two partition plates 31 is smaller when facing each other than when facing away.

[0041] The smaller opening end of the intermediate filter hole 4 is the inlet end, which improves the filtration effect and reduces the chance of stones entering the spherical filter cylinder 2. At the same time, the water entering the inner channel washes the intermediate filter holes 4 of the lower partition plate 31 under the action of water flow. When cleaning, the lower partition plate 31 has a larger downward opening size for the intermediate filter holes 4, which is easier to wash. Of course, stones that have entered the intermediate filter holes 4 of the lower partition plate 31 can also be more easily removed downwards under the action of gravity.

[0042] In this embodiment, both partition plates 31 are conical in shape, with their conical ends extending towards each other and simultaneously fixedly connected to the fixing rod 32.

[0043] The edges of the two partition plates 31 are far apart, forming a larger inner channel to allow more water to enter and be filtered out. At the same time, the opposing sides of the two partition plates 31 that connect to the inner channel are inclined slopes, directly receiving the water flow entering the inner channel. This water flow can more directly impact the various intermediate filter holes 4 on the two partition plates 31, and the impact of the water flow can more thoroughly flush the various intermediate filter holes 4 on the two partition plates 31, preventing the various intermediate filter holes 4 on the two partition plates 31 from becoming blocked. Meanwhile, for the various intermediate filter holes 4 of the upper partition plate 31, the upper side of the upper partition plate 31 forms a downward conical structure, so that stones deposited on the upper partition plate 31 can roll down to the middle position of the upper partition plate 31 under the action of gravity, reducing the probability of the various intermediate filter holes 4 of the upper partition plate 31 being blocked, thereby achieving long-term effective filtration and drainage.

[0044] Please see Figure 2-4In this embodiment: the filter frame 1 further includes a vertically arranged support frame 11 and a spherical frame 12 whose lower end is fixedly connected to the upper end of the support frame 11. The support frame 11 is provided with a lower channel that connects to the downward-opening inlet and outlet 21. The side wall of the spherical frame 12 forms a middle channel that connects to each intermediate filter hole 4. The spherical filter cylinder 2 is rotatably connected to the spherical frame 12, and its outer side abuts against the inner side of the spherical frame 12. The underwater motor 5 is installed on the spherical frame 12, and the lower end of the connecting pipe 13 is fixedly connected to the upper end of the spherical frame 12.

[0045] When the device is hoisted into the mine, the support frame 11 provides support. During the filtration operation, sewage enters the spherical filter cylinder 2 through the lower channel, the middle channel, and the middle filter hole 4, and is filtered out. After long-term use, the spherical filter cylinder 2 is rotated 180° by starting the underwater motor 5. When the partition plate group 3 rotates 180°, the spherical filter cylinder 2, which is on the outer side of the spherical frame 12, rotates relative to the spherical frame 12. The stationary spherical frame 12 scrapes away the debris adhering to the outer wall of the spherical filter cylinder 2, preventing the lateral filter holes 22 on the side wall of the spherical filter cylinder 2 from becoming blocked and affecting the normal use of the spherical filter cylinder 2.

[0046] The support frame 11 includes multiple vertically arranged vertical plates and at least one ring that is simultaneously fixedly connected to each vertical plate. A lower channel for sewage to pass through is formed between the vertical plates, and each vertical plate has an independent support point at its lower end to ensure that the contact area is minimized and to form a stable support for the device.

[0047] Based on the above embodiment, the outer sides of both spherical plates abut against the inner side of the spherical frame 12.

[0048] In this embodiment: the spherical frame 12 includes multiple circumferentially spaced arc rods 121 distributed on the same spherical surface and a weft rod 122 that is fixedly connected to each arc rod 121. The upper and lower ends of each arc rod 121 are fixedly connected to the support frame 11 and the connecting pipe 13, respectively, and a middle channel is formed between each arc rod 121. The inner sides of the weft rod 122 and each arc rod 121 abut against the outer side of the spherical filter cylinder 2. The underwater motor 5 is fixedly installed on one of the arc rods 121.

[0049] After long-term use, by starting the underwater motor 5, the spherical filter cartridge 2 is rotated 180°. When the partition plate assembly 3 rotates 180°, the outer sides of the two spherical plates of the spherical filter cartridge 2 are always in contact with the inner sides of the weft rod 122 and each warp rod 121, so that the debris adhering to the two spherical plates is scraped off by the weft rod 122 and each warp rod 121, thus maintaining the filtration capacity.

[0050] Based on the above embodiment, two opposing arc rods 121 are provided with shaft holes located on the same straight line to allow the two shafts 34 to be rotatably installed.

[0051] Based on the above embodiment, the side filter hole 22 has a trumpet hole structure, and its opening diameter facing the inner side of the spherical filter cylinder 2 is larger than the outer opening diameter to improve the filtration effect. When the debris adhering to the two spherical plates is scraped off by the weft rod 122 and each arc rod 121, the debris entering the side filter hole 22 can be pushed by the weft rod 122 or each arc rod 121 and enter the spherical filter cylinder 2 due to the increase in the inward diameter of the side filter hole 22, thereby reducing the probability of the side filter hole 22 being blocked.

[0052] In this embodiment: a protective cover 123 is fixedly installed on one of the arc rods 121, and the underwater motor 5 is sealed and installed inside the protective cover 123 so as to protect the underwater motor 5 through the protective cover 123.

[0053] As one of the power supply methods known to those skilled in the art, a battery is installed inside the protective cover 123 to supply power to the underwater motor 5; as another of the power supply methods known to those skilled in the art, an opening is made in the protective cover 123 and a wire is sealed and connected to it so as to supply power to the underwater motor 5 through the wire.

[0054] Please see Figure 2-4 In this embodiment, the energy-saving filtration device for mining also includes a baffle 6. The edge end of the baffle 6 is circumferentially fixed to the inner side of the connecting pipe 13. The baffle 6 has multiple upper filter holes 61 through it. The diameter of the upper filter holes 61 is smaller than the diameter of the side filter holes 22 and the middle filter holes 4.

[0055] When the wastewater that has been filtered and enters the spherical filter cartridge 2 is discharged through the connecting pipe 13, the baffle 6 can form a further filtration action to prevent stones that have entered the spherical filter cartridge 2 from being discharged, thereby reducing the chance of the equipment being blocked and damaged.

[0056] Based on the above embodiments, the upper filter hole 61 has a trumpet hole structure with a smaller opening at the top and a larger opening at the bottom to reduce the chance of it being blocked.

[0057] In this embodiment, the baffle 6 has an arc-shaped plate structure, and the curved surface of its lower side coincides with the curved surface of the outer side of the spherical filter cylinder 2.

[0058] During the rotation of the spherical filter cartridge 2, the rotating spherical filter cartridge 2 can scrape and clean the lower side of the baffle 6, reducing the chance of the upper filter hole 61 of the baffle 6 being blocked.

[0059] Based on the above embodiments, since the upper filter hole 61 is a funnel-shaped structure with a smaller opening at the top and a larger opening at the bottom, the stones blocking the upper filter hole 61 can be cleaned under the dual action of gravity and scraping by the spherical filter cylinder 2.

[0060] Please see Figure 1-5 In this embodiment, the energy-saving filtration device for mining also includes a protective frame 7. The upper end of the protective frame 7 is fixedly connected to the connecting pipe 13, and the lower end extends downward and covers the outside of the spherical filter cylinder 2 and the underwater motor 5. The protective frame 7 also forms an external channel for water supply.

[0061] The protective frame 7 forms a secondary support structure, which improves the stability of the filter device. At the same time, the protective frame 7 protects the spherical filter cylinder 2 and the underwater motor 5, preventing large rocks in the well from rolling and causing impact damage to the spherical filter cylinder 2 and the underwater motor 5.

[0062] Example 2 This embodiment provides an energy-saving filtration method for mining operations, including the following steps: S1. The energy-saving filtration device for mining is hoisted to the bottom of the mine water accumulation, supported and fixed by the filter frame 1, and the upper end of the connecting pipe 13 is connected to the water pump through the pipeline to the drainage point. S2. Start the water pump to allow the mine water to enter the spherical filter cylinder 2. After being filtered by the middle filter hole 4 of the partition plate group 3 and the side filter hole 22 of the spherical filter cylinder 2, it is discharged through the connecting pipe 13. S3. During the filtration process, the water flowing into the inner channel flows downward to flush the middle filter hole 4 of the lower partition plate 31, achieving self-cleaning. S4. After long-term use, start the underwater motor 5 to drive the spherical filter cartridge 2 to rotate 180°, so that the accumulated gravel on the partition plate assembly 3 is discharged through the downward-opening inlet and outlet 21 under the action of gravity.

[0063] Furthermore, in step S4, during the rotation process, the outer sides of the two spherical plates of the spherical filter cylinder 2 abut against the inner sides of the weft rod 122 and the longitudinal arc rod 121 to achieve scraping and cleaning of the lateral filter holes 22. The lateral filter holes 22 are funnel-shaped structures with larger inward openings, which facilitates scraping in debris and discharging it inward.

[0064] Furthermore, it also includes step S5, in the discharge process, secondary filtration is performed through the upper filter hole 61 of the baffle 6. The diameter of the upper filter hole 61 is smaller than that of the side filter hole 22 and the middle filter hole 4, and it is a funnel hole structure with a smaller opening at the top and a larger opening at the bottom. Furthermore, when the spherical filter cartridge 2 rotates, the lower side of the baffle 6 is scraped off on its outer side, and the blockage in the upper filter hole 61 is cleared.

[0065] Furthermore, in step S1, the spherical filter cylinder 2 and the underwater motor 5 are covered by the protective frame 7 to form secondary support and protection, and the water flows in through the outer channel of the protective frame; The underwater motor 5 is powered by a battery or sealed wires inside the protective cover 123, and its rotation only starts intermittently when there is buildup that needs to be cleaned, thus achieving energy saving.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
