Description

Technical Field

[0001] This invention belongs to the field of mineral processing equipment technology, specifically relating to a high-efficiency and energy-saving slurry treatment device with simple structure, high filtration efficiency, no additional energy consumption, and stable and reliable operation. Background Technology

[0002] In the entire process of mining and mineral processing, slurry wastewater, as a core associated waste, is widely generated in multiple stages such as mining, crushing, washing, and backfilling. This slurry wastewater not only carries a large amount of solid impurities such as ore fragments, silt, and tailings particles, but also often contains residual mineral processing reagents. If discharged directly, it will cause serious ecological and environmental problems such as soil compaction and water pollution, disrupting the surrounding ecological balance. Furthermore, the insufficiently recovered mineral resources and recyclable water resources in the slurry waste, which contradicts the industry's development requirements for green mine construction and resource recycling.

[0003] More significantly, mining operations are often located in remote areas far from urban core power grids, making insufficient power supply a key bottleneck restricting production. Most remote mining areas rely on temporary power supply equipment such as diesel generators to ensure production, resulting in high energy costs, low power generation efficiency, poor operational stability, noise and exhaust pollution. Traditional slurry treatment technology is highly dependent on external power, with its core drawbacks manifesting in enormous energy consumption and low utilization: traditional slurry treatment equipment requires continuous external power to drive core components such as pumps, filters, and conveying devices to complete processes like slurry transport, impurity separation, and solid-liquid separation. Due to the large volume and long duration of slurry generated in mining operations, related equipment needs to operate continuously for extended periods, leading to persistently high power consumption. This significantly increases production costs for mining companies and further exacerbates the energy supply pressure in remote mining areas.

[0004] In addition, traditional slurry treatment equipment faces several challenges: First, there is a high risk of sludge blockage. Solid particles in the slurry easily adhere to the filter holes, pipes, and gaps in the transmission components. Especially when the filtration mechanism is stationary or running at low speed, the accumulation of impurities can easily cause blockage of the filter holes and obstruction of the pipes, requiring frequent shutdowns for cleaning, which seriously affects the treatment efficiency. Second, maintenance is inconvenient. Existing equipment is mostly an integrated fixed structure, and the disassembly and assembly of core components such as filter components and transmission components are cumbersome. Once a malfunction or blockage occurs, a large amount of manpower and resources are required to disassemble the equipment, resulting in long maintenance cycles and high costs. Third, operational stability is poor. During operation, some rotary filtration devices are prone to significant vibration and jamming due to fluctuations in slurry supply, uneven force caused by solid particle adhesion, and insufficient positioning accuracy. This not only accelerates component wear and shortens the service life of the equipment but may also lead to seal failure at the connection points, causing slurry leakage and other safety hazards.

[0005] Although a few devices have emerged in the existing technology that attempt to recover energy from slurry (such as hydraulic power generation heating and filtration devices for filling pipes in some mines, and coal-water slurry potential energy recovery power generation devices), these devices generally have design flaws: some devices can only recover a small portion of the energy from the slurry and still require external power to drive key transmission components and filtration mechanisms, failing to achieve fully autonomous operation; other energy recovery devices have complex structures, poor operational stability, and are disconnected from the slurry treatment process, failing to simultaneously and efficiently complete slurry purification and energy recovery, thus still failing to solve the practical problems of huge energy consumption, serious resource waste, and blockage, difficult maintenance, and vibration.

[0006] Therefore, developing a highly efficient and energy-saving slurry treatment device that requires no or only a small amount of external power, has a simple and reliable structure, high filtration efficiency, can simultaneously recover the potential energy of slurry and separate solids and liquids, avoids silt blockage, is easy to maintain, and operates stably has become an urgent technical need to be addressed in the mining industry. Summary of the Invention

[0007] To address the problems mentioned in the background section, this invention provides a high-efficiency and energy-saving slurry treatment device that is simple in structure, has high filtration efficiency, consumes no additional energy, and operates stably and reliably.

The filtering rotation unit includes a filter cylinder that is rotatably sleeved on the slurry conveying unit and located above the support base II. The filter cylinder has several filter holes. A flow guide platform is fixedly provided on the top of the support base II below the filter cylinder. Several circumferentially distributed rotating blades are fixedly arranged at intervals along the length of the filter cylinder and correspond to the outlets of several water spray pipes on the slurry conveying unit.

[0009] Furthermore, the top of the support base II is vertically fixed with parallel filter baffles near the slurry buffer tank and the support base III, respectively.

The inlet of the slurry conveying pipe is connected to the lower part of the slurry buffer tank and multiple rotating positioning rings are fixedly sleeved at intervals along the length direction.

Multiple water spray pipes are provided at intervals between two adjacent rotating positioning rings in the slurry conveying pipe. The filter rotation unit also includes multiple rotating collars, telescopic slides, and auxiliary springs that are coaxially fixedly spaced inside the filter cylinder and correspond to the rotating positioning ring.

The connecting strips are fixedly connected to the two auxiliary rings at both ends of the filtration rotating unit and each filter cylinder.

[0012] Furthermore, the inner wall of the filter cylinder is provided with several T-shaped slots evenly distributed circumferentially on both sides of the support column. The rotating cylinder blades are bent plate-shaped or spiral blades. The ends of the rotating cylinder blades are fixedly provided with T-shaped blocks that can be slidably disposed in the T-shaped slots.

[0013] Furthermore, the top center of the guide platform is provided with a guide groove extending from the slurry buffer tank to the support seat III and having a "V" or "Y" shaped cross-section. The inlet of the outlet pipe III is connected to the guide groove of the guide platform. The top of the guide platform has positioning grooves on both outer sides of the guide groove. The guide platform is fitted with an inverted "U" or inverted "U" shaped protective cover. The bottom of both sides of the protective cover is provided with positioning blocks that can be engaged in the positioning grooves.

[0014] Furthermore, the drainage and diversion unit also includes a detachable drainage sealing frame fixedly installed at the top of the sealable space below the support base II. The top of the drainage sealing frame is fixedly provided with a protrusion that extends upward into the diversion groove and seals against it. The bottom of the drainage sealing frame is provided with multiple water outlet pipes III spaced apart along the length of the diversion platform. The water outlet pipes III are bent and the water outlet faces the side below the length of the diversion platform. The water inlet of the water outlet pipes III passes through the drainage sealing frame and communicates with the diversion groove of the diversion platform.

[0015] Furthermore, the bottom and lower part of the slurry buffer tank are respectively fixedly provided with water outlet pipe I and water outlet pipe II, and water outlet pipe I and water outlet pipe II are respectively connected to gate valves. The outlet end of the gate valve connected to water outlet pipe II is connected to the water inlet of the slurry conveying unit.

[0016] Furthermore, the rotating impeller unit also includes multiple blade assemblies that are detachably spaced and sleeved on the blade shaft and correspond to each water outlet pipe III. Each blade assembly includes a fixing ring that is detachably and fixedly connected to the blade shaft, and a connecting ring that is coaxial with the fixing ring and fixedly connected to each other by a plurality of circumferentially distributed connecting arms. A plurality of blades are circumferentially and evenly fixed to the outer surface of the connecting ring. The sealable space below the support base II is hinged to at least one side along the blade shaft extension direction and has an openable and closable protective door. A drain pipe is provided at the bottom end of the support base II.

[0017] Furthermore, the energy output unit also includes a bevel gear box, which is fixedly disposed below the support base III. Inside the bevel gear box, bevel gear shafts I and II are rotatably disposed perpendicularly to each other. Bevel gear I is fixedly fitted onto the adjacent ends of bevel gear shafts I and II. The end of bevel gear shaft I away from bevel gear I rotatably passes through the bevel gear box and connects to the blade shaft. The end of bevel gear shaft II away from bevel gear I rotatably passes through the support base III and is fixedly fitted with bevel gear II. The generator is disposed on the top of the support base III, and bevel gear II is fixedly fitted onto its rotating shaft. The bevel gear II on the generator rotating shaft meshes with the bevel gear II on the bevel gear shaft II.

[0018] The present invention has the following beneficial effects: 1. This invention employs a filter screen at the top of the slurry buffer tank for initial interception, preventing large impurities from entering subsequent pipelines and reducing the risk of clogging in pipelines and filter components from the source. Combined with the outlet pipe and gate valve to periodically discharge sludge from the tank, it ensures smooth slurry delivery. The slurry then passes through a conveying and filtering mechanism, where rotating blades on the filter cylinders are driven to rotate by the impact of the slurry. The filter holes on the filter cylinder walls create a dynamic sieving effect during rotation, effectively separating fine solid particles, thereby improving purification efficiency and preventing static clogging. This dual design of "pre-filtration + dynamic rotational filtration," along with auxiliary rings and connecting strips driving multiple filter cylinders to operate synchronously, significantly improves overall filtration efficiency, making it particularly suitable for mining slurries with high impurity concentrations.

[0019] 2. This invention requires no external power drive, relying solely on the potential energy of the flowing slurry to complete filtration and power generation: Upon entering the slurry buffer tank, the slurry automatically undergoes coarse filtration by passing through the filter screen using its potential energy. It then exits the buffer tank via a spray pipe, impacting the rotating blades and driving the filter cylinder to rotate, achieving secondary filtration. The filtered slurry then impacts the blades through a bent outlet pipe III, causing the blade shaft to rotate, and finally, the energy is transmitted to the generator via a bevel gear box. This interconnected "secondary filtration-impact power generation" design converts the slurry's potential energy into mechanical energy and further into electrical energy, achieving resource recycling while minimizing energy transfer losses and solving the power supply problem in remote mining areas.

[0020] 3. The filter rotation unit of the present invention forms an overall frame through multiple filter cylinders and connecting strips connected end to end. The auxiliary rings and support columns are evenly distributed, effectively dispersing the centrifugal force of rotation and avoiding vibration caused by excessive force at a single point. Moreover, the telescopic sliding column is always pressed against the rotation groove of the rotation positioning ring under the action of the auxiliary spring, forming a buffer damping, thereby absorbing the impact vibration during operation and compensating for assembly errors, effectively improving the operational stability of the filter cylinder and preventing deviation and jamming. Combined with multi-stage filtration, it can ensure the cleanliness of the slurry, prevent impurities from wearing the blades and other transmission components, and significantly extend the service life of the device.

[0021] 4. The support frame and multiple sets of support seats of the present invention form a stable bearing platform, ensuring the assembly accuracy of each mechanism; and key components such as filter cylinder, rotary blades, and impeller kits all adopt standardized interfaces (such as T-shaped slots and fixing rings), so they can be quickly disassembled and assembled without special tools, and can also support partial replacement rather than overall scrapping, reducing maintenance costs; and the U-shaped protective cover is connected to the guide plate positioning slot through the positioning block, and the protective door is hinged at the front end of the support seat II, all of which can be quickly disassembled and assembled, providing an open maintenance channel for the inspection and maintenance of internal filter cylinder, rotary blades and other components, thereby effectively shortening maintenance time.

[0022] In summary, this invention, through its ingenious energy cascade utilization mechanism (two-stage potential energy filtration, with residual potential energy used for power generation), innovative anti-vibration and anti-clogging structural design, and highly modular and maintainable layout, achieves an organic combination of slurry filtration, energy recovery, and structural stability. It successfully solves the core problems of traditional slurry treatment equipment, such as high energy consumption, easy clogging, difficult maintenance, short lifespan, and high energy consumption. It is especially suitable for the purification and treatment of slurry generated in mining, crushing, washing, and filling processes, and is an important technical equipment for promoting the green and intelligent transformation and upgrading of the mining industry.

Each support column 33 has a telescopic hole with its bottom end penetrating through the rotating collar 34. The telescopic slides 15 are slidably disposed within the telescopic holes of the support columns 33, and their bottom ends can slide into the rotation groove of the rotating positioning ring 31. The auxiliary springs 16 are movably disposed within the telescopic holes of the support columns 33 away from the rotating collars 34. The two ends of the auxiliary springs 16 abut against the bottom end of the telescopic hole and the end face of the telescopic slides 15 away from the rotating collars 34, respectively.

[0029] like Figure 6As shown, the telescopic hole provided in the support column 33 is a blind hole, and the outer wall of the support column 33 has a groove 39 extending along the length and communicating with the telescopic hole on at least one side. The end face of the telescopic sliding column 15 away from the rotating collar 34 is fixedly provided with a slider 40 that can slide into the groove 39.

The outer end faces of the filter cylinders 13 at both ends of the filtration rotating unit are respectively fixedly provided with auxiliary rings 29. The two ends of the slurry conveying pipe 12 respectively movably pass through two auxiliary rings 29. The outer surface of the filtration rotating unit is fixedly provided with several circumferentially distributed connecting strips 30 along the length direction. The connecting strips 30 are fixedly connected to the two auxiliary rings 29 at both ends of the filtration rotating unit and each filter cylinder 13.

[0031] like Figure 5 and 6 As shown, the inner wall of the filter cylinder 13 is evenly distributed with several T-shaped slots on both sides of the support column 33. The rotating blade 14 is a bent plate or a spiral blade. The end of the rotating blade 14 is fixedly provided with a T-shaped block that can be slidably disposed in the T-shaped slot.

The bevel teeth Ⅱ26 on the rotating shaft of the generator 27 mesh with the bevel teeth Ⅱ26 on the bevel gear shaft Ⅱ24.

[0037] The working principle and process of this invention: like Figures 1 to 7As shown, before the device is started, the support frame 1 serves as the core load-bearing structure. Support base I2 and support base III4 are fixed on its top two sides respectively, and support base II3 is set between them, forming a stable upper installation platform to provide solid support for the subsequent assembly of various mechanisms. The bottom end of the slurry buffer tank 5 is fixed to the top of the support base I2; the pretreatment and buffering stage of the slurry is completed by the slurry buffer tank 5 and its supporting components; the slurry to be filtered is poured into the top of the slurry buffer tank 5, and the filter screen 6 set on the upper gasket of the inner wall can initially intercept the slurry, preventing large impurities from entering the tank body and avoiding blockage of subsequent pipelines and components; the bottom and lower part of the slurry buffer tank 5 are respectively equipped with water outlet pipe I7 and water outlet pipe II8, and one end of each water outlet pipe is connected to the corresponding gate valve 9 through a flange to realize the control of pipeline opening and closing. The bottom end of the outlet pipe I7 passes through the support I2, and the gate valve 9 on it is located between the support frame 1 and the support I2. The core function of this pipe and the gate valve 9 is to discharge the sludge accumulated in the slurry buffer tank 5. By periodically opening the gate valve 9, the sludge settled at the bottom of the tank can be discharged, ensuring the cleanliness of the tank and preventing sludge from affecting the storage and subsequent transportation efficiency of the slurry. The transportation and filtration of the slurry is handled by the transportation and filtration mechanism. This mechanism includes a slurry transportation unit and a filtration rotation unit, both of which are located on the top of the support II3. The filtration rotation unit is rotated and sleeved on the slurry transportation unit, and the transportation and filtration of the slurry are achieved through mutual transmission. After the slurry has undergone initial interception in the slurry buffer tank 5, the gate valve 9 connected to the outlet pipe II 8 is opened, and the slurry is then transported through the outlet pipe II 8 to the slurry conveying pipe 12 of the slurry conveying unit, completing the directional conveying of the slurry. The slurry conveying pipe 12 is provided with multiple equidistantly distributed rotating positioning rings 31, and multiple spray pipes 32 are symmetrically arranged between adjacent rotating positioning rings 31. After the slurry enters the slurry conveying pipe 12, it is sprayed outward through the spray pipes 32, utilizing the impact force generated by the sprayed water flow to act on the rotating blades 14 of the filter rotating unit (the rotating blades 14 are bent, with their ends...). The T-shaped locking block at the end engages with the T-shaped locking groove on the inner wall of the filter cylinder 13, enabling stable installation and convenient disassembly of the blades. This drives the rotating blades 14 and the filter cylinder 13 to rotate together. The inner wall of the filter cylinder 13 is fixed with a rotating collar 34 by a support column 33. The rotating collar 34 is fitted onto the rotating positioning ring 31, providing precise positioning for the rotation of the filter cylinder 13. At the same time, the telescopic sliding pin 15 in the telescopic hole inside the support column 33 extends to the rotating groove of the rotating positioning ring 31 under the elastic action of the auxiliary spring 16, further improving the stability of the filter cylinder 13 during rotation and preventing deviation.During the rotation of the filter cylinder 13, multiple through-filtration holes on its inner wall filter the slurry, intercepting fine particles in the slurry inside the filter cylinder 13, thus separating the slurry from impurities. The auxiliary rings 29 connected to the end faces of the two outermost filter cylinders 13 and the connecting strips 30 fixed to the outer wall enable multiple filter cylinders 13 to rotate synchronously, improving the overall filtration efficiency. The filter baffles 10 on both sides of the top of the support base II3 can block the slurry splashing during the filtration process. The protective cover 11 on the top is fixed to the positioning slot of the guide table 35 by the positioning block, which can protect the internal components and facilitate disassembly and maintenance.

[0038] The filtered slurry is directed through a drainage guide unit, which consists of a drainage sealing frame 17 and an outlet pipe III 18. The drainage sealing frame 17 extends into the guide groove of the guide platform 35 via a top protrusion, allowing the filtered slurry to flow naturally into the drainage sealing frame 17 along the guide groove. It is then transported downwards through multiple bent outlet pipes III 18 at its bottom, completing the transition of the slurry from the filtration stage to the energy conversion stage. The sealing design of the drainage sealing frame 17 prevents slurry leakage, ensuring that all slurry is transported to the rotating impeller unit below through the outlet pipes III 18. Simultaneously... The energy conversion process is completed by an energy conversion mechanism, which includes a rotating impeller unit and an energy output unit. The rotating impeller unit is located in a sealable space below the support base II3, and the energy output unit is fixed to the top of the support base III4. The conversion of potential energy into electrical energy is achieved through the transmission between the two. When the water outlet of the water outlet pipe III18 discharges water, the impact force generated by the falling water acts on the blades 21 of the rotating impeller unit (the blades 21 are bent to maximize the absorption of the water flow impact force), driving the blade assembly 20 and the blade shaft 19 to rotate together. The two ends of the blade shaft 19 The rotating support II3 ensures smooth rotation, and one end of it is connected to the bevel gear shaft I23 of the energy output unit, transmitting rotational power to the inside of the bevel gear box 22. The bevel gear box 22 is fixed below the support III4, and the bevel gear shafts I23 and II24, which are rotatably mounted inside, are vertically distributed. The bevel gears I25 on both mesh with each other, converting the horizontal rotational power transmitted from the blade shaft 19 into vertical rotational power. The other end of the bevel gear shaft II24, away from the bevel gear I25, extends through the bevel gear box 22 and the support III4 to the inside of the top protective frame, and the bevel gear II at its top... The bevel gear 26 on the shaft of generator 27 meshes with the shaft of generator 27, further transmitting power to the shaft of generator 27. Generator 27 is installed inside the protective frame. When the shaft rotates, it will undergo relative line cutting motion with the induction coil inside generator 27. According to the principle of electromagnetic induction, mechanical energy is converted into electrical energy, thereby powering the relevant equipment of the mining enterprise and completing the entire process of slurry potential energy conversion. The protective frame can protect generator 27 and bevel gear transmission components, avoiding interference from external impurities and accidental collision damage, ensuring stable and efficient operation of energy conversion. Multi-stage filtration ensures the cleanliness of slurry, avoids component wear, and significantly improves the energy efficiency and service life of the device. The gate valve 9 corresponding to the outlet pipe I7 can be opened periodically to clean sludge. The protective door 28 at the front end of support II3 facilitates the inspection and maintenance of internal components, further ensuring the long-term stable operation of the device.
