Description

Technical Field

[0001] This invention relates to the field of solid-liquid separation technology, and in particular to a cyclone sedimentation device for recovering high-purity copper powder precipitates. Background Technology

[0002] In fields such as machining, electronic waste recycling, and mineral processing, mixed waste liquids containing solid particles of various densities are frequently generated. For example, during copper rolling, the rolling oil may contain copper powder (density approximately 8.5 g / cm³), soil (density approximately 2.4-2.7 g / cm³), and diatomaceous earth (bulk density approximately 0.3-0.6 g / cm³) used as a filter aid. Efficiently separating and classifying these particles of different densities, especially the high-value copper powder, from high-viscosity oil media is a significant technical challenge in industrial production.

[0003] Existing cyclone sedimentation tanks (such as standard OW, OWK, and OWR types) can achieve a certain degree of solid-liquid separation, but they have the following shortcomings: 1. Traditional OW type sedimentation tanks use a simple tangential inlet structure, which, although low in cost, has low separation efficiency for small-diameter particles and significant liquid backlog. 2. While OWR type sedimentation tanks improve the separation efficiency for small particles through the downward extension pipe and elbow structure, they are mainly suitable for circular tanks, where impurities are evenly distributed circumferentially, making centralized collection difficult. 3. Existing devices cannot simultaneously process multiple particulate matter with significant density differences within the same equipment—increasing centrifugal force is beneficial for separating heavy particles, but it will break up light flocs; reducing flow rate will lead to a decrease in the settling efficiency of heavy particles. 4. For high-viscosity media (such as rolling oil), traditional designs do not consider the influence of viscosity on particle settling velocity, resulting in unreasonable residence time design.

[0004] In summary, while traditional hydrocyclones can achieve rapid solid-liquid separation using centrifugal force, they suffer from limited separation precision, easy loss of fine copper powder with overflow, and the presence of a large amount of water entrained in the underflow, resulting in insufficient purity of the recovered copper powder precipitate. Furthermore, during sludge discharge, existing hydrocyclone devices are prone to re-introducing precipitated copper powder into the cyclone field due to eddy current entrainment, leading to a decrease in separation efficiency. Simultaneously, trace amounts of heavy particles can easily mix into the purified liquid during the lifting process, affecting the final effluent quality. Summary of the Invention

The inner wall of the first cone is provided with guide vanes spiraling downwards along the water inlet direction.

[0010] Optionally, the water inlet pipe enters the inner cavity of the cyclone separator and descends vertically along the side wall of the columnar inner cavity to the upper end of a section of the cone, where a tangential bend is fixedly connected. The outlet direction of the tangential bend is tangential to the inner wall of the section of the cone and inclined downwards. The horizontal deflection angle of the tangential bend is 30°-60°, and the vertical downward inclination angle is 15°-45°.

[0011] Optionally, the upper end of the sludge collection pipe has a truncated cone-shaped anti-winding ring that is narrower at the top and wider at the bottom. The anti-winding ring is abutted at the lowest point of the sludge collection base plate. A gap of 0.10-0.15 mm is left between the upper end of the anti-winding ring and the lower end of the two conical sections. The lower end of the anti-winding suction ring has a columnar structure with consistent upper and lower diameters in the collection pipe. One-way settling plates are vertically spaced evenly at the upper end of the collection pipe near the anti-winding suction ring. Each one-way settling plate has a triangular blade-like structure, narrow at the top and wide at the bottom. Sequential gate valves are installed at both ends of the lower collection pipe. Gate plates are slidably inserted into each gate valve, staggered left and right. The two gate plates are fixedly connected by a Z-shaped interlocking component.

The piston rod of the sequential cylinder is fixedly connected to the corresponding gate plate. When the piston rod extends, the lower sequential gate valve opens, and the upper sequential gate valve closes to cut off the flow.

[0012] Optionally, a sealing guide ring is embedded at the bottom edge of the top seal seat. The sealing guide ring is a U-shaped ring structure with an opening facing downwards. The width of the sealing guide ring is consistent with the width of the guide fin. A fixed sleeve is vertically inserted through the top seal seat in the middle of the sealing guide ring. The purified liquid lifting conduit is vertically inserted and rotatably installed in the inner cavity of the fixed sleeve. A cap ring with a narrow top and a wide bottom is provided at the end of the fixed sleeve below the sealing guide ring. The edge of the cap ring covers the rotational movement area of ​​the purified liquid lifting conduit below. A buffer area is left between the cap ring and the sealing guide ring.

[0013] Optionally, the outer wall of the purified liquid lifting conduit below the cap ring is provided with spirally distributed auxiliary swirling fins. The spiral direction of the auxiliary swirling fins is opposite to the water inlet direction of the inlet pipe. When the auxiliary swirling fins rotate with the purified liquid lifting conduit, they accelerate the downward swirling transport of the high-viscosity medium near the tangential bend. A retaining ring is provided in the middle of the purified liquid lifting conduit, which is engaged with the inner cavity of the fixed sleeve. The lower end of the purified liquid lifting conduit is connected to a spindle-shaped separation extension pipe with narrow ends and a wide middle section. The upper conical surface length of the separation extension pipe is less than the lower conical surface length, and the taper of the lower conical surface of the separation extension pipe is consistent with the taper of a section of the cone. The upper part of the purified liquid lifting conduit... The end of the liquid lifting conduit passes through the separation drive seat, and a worm gear is fixedly installed at a position corresponding to the separation drive seat on the liquid lifting conduit. The lower end of the separation extension pipette is provided with an outward-curving outer reflux ring, and the inside of the outer reflux ring is provided with an inner reflux ring with a narrower diameter. The channel between the outer reflux ring and the inner reflux ring gradually widens from top to bottom. Impurities contained in the light medium entering the liquid lifting conduit are separated again during the lifting process and slide down along the inner wall of the separation extension pipette, sliding out from the channel between the outer reflux ring and the inner reflux ring. The direction of sliding out corresponds to the swirling path of the medium in a section of the cone. The upper end of the liquid lifting conduit is provided with an overflow bevel that slopes outward and downward.

[0014] Optionally, a separation motor is provided on one side of the separation drive seat. The separation motor is a waterproof motor. The shaft of the separation motor is rotatably connected to a worm gear through a coupling. The worm gear meshes with a worm wheel, and the rotation of the worm wheel drives the clean liquid lifting conduit to rotate.

[0015] Optionally, the upper end of the active lifting frame is equipped with a lifting motor. The ring edge of the active lifting frame is suspended and mounted on the upper end of the housing of the separation drive seat via a long-legged screw. A lifting shaft is rotatably mounted in the middle of the active lifting frame. The lifting shaft is positioned downwards in the middle of the inner cavity of the purified liquid lifting conduit. A spiral lifting screw is provided on the lifting shaft corresponding to the inner cavity of the purified liquid lifting conduit. The edge of the lifting screw is tangent to the inner cavity of the columnar end of the purified liquid lifting conduit. A gap is left between the edge of the lifting screw and the inner edge of the separation extension tube. The bottom of the active lifting frame... A diversion cone, wider at the top and narrower at the bottom, is fixed on the lifting shaft. The diversion cone and the lifting shaft below form a hollow structure. The lower end of the lifting shaft is open. The cone surface of the diversion cone has spirally distributed water outlet holes. One side of the water outlet holes has spirally distributed guide fins. A small portion of the light medium in the middle of the cyclone separator rises straight through the inner cavity of the lifting shaft and flows out from the water outlet holes of the diversion cone. During the outflow process, it is thrown out with the rotation of the diversion cone. Most of the light medium is lifted upward by the lifting screw.

[0016] A method for recovering high-purity copper powder precipitate by hydrocyclone precipitation includes the following steps: S1 Liquid Inlet Cyclone: ​​The copper powder mixture to be treated is introduced through the water inlet pipe and enters the cyclone separator tangentially through the tangential elbow 501 at a horizontal deflection of 30°-60° and a downward tilt angle of 15°-45°, forming a high-speed external cyclone. S2 graded separation: Copper powder with a density greater than 8 g / cm³ descends along the inner wall of the cyclone separator to the bottom plate of the sludge collection under the action of centrifugal force, while soil particles with a density of 2-3 g / cm³ settle on the settling plate, and the light purified liquid forms an inner vortex in the center and flows upward. S3 Secondary Separation of Purified Liquid: The purified liquid lifting conduit rotates to extract the central purified liquid, and the return channel at the lower end of the separation extension pipe separates the mixed trace heavy particles and returns them to the swirling field. The purified liquid is then lifted to the upper part of the sedimentation tank by the active lifting component. S4 Continuous Sludge Discharge: The timing cylinder drives the upper and lower gates to open and close alternately, continuously discharging high-concentration copper powder precipitates without interrupting the processing flow. The sludge discharge concentration is ≥30%.

[0017] This invention provides a hydrocyclone sedimentation device for recovering high-purity copper powder precipitates, which has the following beneficial effects: 1. The cyclone sedimentation device for recovering high-purity copper powder precipitates proposed in this invention achieves efficient recovery of copper powder precipitates and continuous separation of the purified liquid through the coordinated operation of the cyclone separator, the purified liquid lifting system, the two-stage anti-entrapment mechanism of the sludge collection pipe, and the multi-stage settling structure in the sedimentation tank. The cyclone separator adopts a two-section conical structure with a columnar upper end and a gradually increasing lower end. The first section of the cone has a taper of 5°, and the second section has a taper of 10°. Guide fins are spirally arranged downward along the water inlet direction on the inner wall of the first section of the cone, which enables the mixed liquid to maintain a high tangential velocity in the cyclone field while gradually increasing the axial velocity, effectively enhancing the solid-liquid separation effect. The tangential bends jet the liquid at an angle of 30° to 60° horizontal deflection and 15° to 45° downward tilt, ensuring that the mixed liquid enters the cyclone field at the optimal incident angle, forming a stable external cyclone and providing reliable power for centrifugal separation.

[0018] 2. In the purified liquid lifting system of the present invention, the outer wall of the purified liquid lifting conduit is provided with auxiliary swirling fins opposite to the direction of water inlet. When rotating, these fins can accelerate the downward swirling transport of high-viscosity media near the tangential bend, preventing high-concentration slurry from stagnating in the separation zone. The separation extension pipe adopts a shuttle-shaped structure, with its lower end tapering consistent with a section of cone, enabling it to accurately extract purified liquid from the low-pressure zone at the center of the swirling flow field. The reflux channel formed by the outer and inner reflux rings at the lower end of the separation extension pipe, which gradually expands from top to bottom, allows trace amounts of heavy particles mixed in during the lifting process to slide down the pipe wall and return along the swirling flow path, achieving secondary separation and significantly improving the purity of the purified liquid extraction.

[0019] 3. The lifting spiral in the active lifting frame of the present invention is tangent to the inner cavity of the purified liquid lifting conduit, forming a forced upward spiral pushing force, which greatly improves the lifting efficiency and head of the purified liquid. The spirally distributed water outlet holes and guide fins on the diversion cone realize the balanced distribution of pressure during the lifting process and reduce energy loss.

[0020] 4. The settling plates on the four side walls of the sedimentation tank of the present invention adopt an inclined structure that slopes towards the center, which effectively expands the natural settling area and prevents solids from adhering to the side walls; the vertical baffle effectively isolates the turbulence at the outlet of the cyclone separator, ensuring that only the surface clarified water flows smoothly into the clean liquid tank through the overflow port; the design of the clean liquid discharge pipe being lower than the bottom of the inlet pipe ensures that the clean liquid has sufficient residence time for final settling.

[0021] 5. The secondary anti-winding mechanism in the sludge collection pipe of this invention includes a truncated cone-shaped anti-winding ring that is narrower at the top and wider at the bottom, and vertically spaced unidirectional settling plates. The anti-winding ring maintains a gap of 0.10 to 0.15 meters with the lower end of the two-section cone, which can effectively prevent the vortex at the center of the swirling field from winding up the bottom sediment. The unidirectional settling plates adopt a triangular blade structure that is narrower at the top and wider at the bottom, so that the sediment can only settle downwards in one direction, preventing sludge back-mixing. The sequential gate valve system links the upper and lower gates through interlocking components, and is controlled by a sequential cylinder to achieve alternating opening and closing. During the sludge discharge process, the inner cavity of the swirling separator and the sludge collection pipe are always isolated, avoiding direct medium flow, and realizing the continuous and stable discharge of high-concentration copper powder precipitate without interrupting the overall treatment process.

[0037] In Example 2, based on Example 1, a lifting motor 1001 is provided at the upper end of the active lifting frame 10. The circumferential edge of the active lifting frame 10 is suspended and mounted on the upper end of the housing of the separation drive seat 9 via a long-legged screw 1005. A lifting shaft 1002 is rotatably mounted in the middle of the active lifting frame 10. The lifting shaft 1002 is positioned downwards in the middle of the inner cavity of the purified liquid lifting conduit 8. A spiral lifting screw 1004 is provided on the lifting shaft 1002 corresponding to the inner cavity of the purified liquid lifting conduit 8. The edge of the lifting screw 1004 is tangent to the inner cavity of the columnar end of the purified liquid lifting conduit 8. A gap is left between the edge of the lifting screw 1004 and the inner edge of the separation extension suction tube 802. The bottom of the active lifting frame 10... A diversion cone 1003, wider at the top and narrower at the bottom, is fixedly mounted on the lifting shaft 1002. The diversion cone 1003 and the lifting shaft 1002 below form a hollow structure. The lower end of the lifting shaft 1002 is an open structure. The cone surface of the diversion cone 1003 is provided with spirally distributed water outlet holes 1031. One side of the water outlet holes 1031 is provided with spirally distributed guide fins 1032. A small portion of the light medium in the middle of the swirling separator 4 rises straight through the inner cavity of the lifting shaft 1002 and flows out from the water outlet holes 1031 of the diversion cone 1003. During the outflow process, it is thrown out with the rotation of the diversion cone 1003. Most of the light medium is lifted upward by the lifting screw 1004.

[0038] Example 3, based on Example 1, is for a viscosity of 50-100 mPa. For high-viscosity copper-rolled oil media, the taper of a section of cone 402 is adjusted to 10°, the vertical downward tilt angle of the tangential bend 501 is adjusted to 45°, the speed of the separation motor 901 is increased to 300 r / min, and the speed of the lifting motor 1001 is increased to 1000 r / min. By increasing the taper and the incident angle, the swirling intensity of the high-viscosity medium is enhanced; increasing the motor speed enhances the lifting capacity of the purified liquid and the auxiliary swirling effect, ensuring that the separation efficiency under high-viscosity media can still reach over 95%.

[0039] The following further explains the function and effect of each structure mentioned above to help those skilled in the art better understand the technical solution: The sedimentation tank 1, as the base of the device, with its square box structure and upper cap design, ensures the airtightness and stability of the entire treatment process. The controller 2 is installed on one outer wall of the sedimentation tank 1 to coordinate the timing of the various components and achieve automated control. The settling plates 101 fixed on the four side walls of the inner cavity of the sedimentation tank 1 have an inner wall that slopes towards the center, and the upper end is cut inward and downward. This design allows the rising purified liquid to slide down the slope as it flows, preventing solids from adhering to the side walls. Simultaneously, the slope structure effectively expands the settling area, enhances the natural settling effect, and ensures the clarity of the water in the purification zone. A vertical baffle 102 is installed at the upper end of the inner cavity of the sedimentation tank 1, near the clean liquid tank 3. Its upper end connects to the cover, and its lower end is lower than the upper end of the cyclone separator 4 but higher than the inlet end of the water inlet pipe 5. This baffle acts as a blockage and guide, preventing the turbulent flow at the outlet of the cyclone separator 4 from directly impacting the overflow area. This ensures that only the surface clarified water can pass over the lower end of the baffle 102 and flow smoothly into the clean liquid tank 3 through the overflow port 103. The sludge collection bottom plate 104 adopts a 5° to 10° conical structure that tilts towards the center. This facilitates the concentration of sediments towards the lowest sludge collection pipe 6 under the action of gravity, improving the thoroughness of sludge removal.

[0040] The cyclone separator 4 is suspended in the middle of the sedimentation tank 1 by a fixing frame 401. It consists of a columnar structure at the top and a first conical section 402 and a second conical section 403 below. The first conical section 402 has a taper of 5°-10°, with an optimal taper of 8°, while the second conical section 403 has a taper of 30°, creating a gradual taper change. This design allows the cyclone liquid to maintain a high tangential velocity in the conical section while gradually increasing the axial velocity, thus enhancing the solid-liquid separation effect. The spirally downward-facing guide vanes 4021 on the inner wall of the first conical section 402 guide the water flow and increase the probability of collision between particles and the wall, promoting the downward movement of heavy phase media such as copper powder along the conical wall. The water inlet pipe 5 is introduced from one side of the sedimentation tank 1 and enters vertically along the inner wall of the cyclone separator 4. The tangential bend 501 at its end is tangential to the inner wall of a section of cone 402 and tilts downward at 15° to 45°, and deflects horizontally at 30° to 60°. This tangential and downward jetting method allows the mixed liquid to enter the cyclone field at the optimal incident angle, forming a stable external cyclone in the cylinder, providing initial power for centrifugal separation.

[0041] The purified liquid lifting system is achieved through the cooperation of the top seal seat 7, the purified liquid lifting conduit 8, the separation drive seat 9, and the active lifting frame 10. The sealing guide ring 701 embedded at the bottom of the top seal seat 7 is a U-shaped ring structure with an opening facing downwards. Its width matches the guide fin 4021, effectively intercepting the medium overflowing from the upper part of the cyclone separator 4 and guiding it into the predetermined flow channel to prevent short-circuit flow. The fixed sleeve 702 vertically penetrates the top seal seat 7, providing stable rotational support for the purified liquid lifting conduit 8. The cap ring 703 is designed as a trumpet shape, narrow at the top and wide at the bottom. Its edge covers the rotational movement area of ​​the purified liquid lifting conduit 8, and the buffer area formed between it and the sealing guide ring 701 effectively dissipates energy, reducing interference from the cyclone to the central lifting area. The separation motor 901 in the separation drive seat 9 meshes with the worm gear 804 on the purified liquid lifting conduit 8 through the worm 902, driving the purified liquid lifting conduit 8 to rotate. The auxiliary swirl vanes 801 on the outer wall of the purified liquid lifting conduit 8 have a spiral direction opposite to that of the water inlet pipe 5. When rotating, they can accelerate the downward swirling transport of high-viscosity media near the tangential bend 501, enhancing the intensity of the external swirling flow and preventing high-concentration slurry from stagnating in the separation zone. The separation extension suction tube 802 at the lower end of the purified liquid lifting conduit 8 has a spindle-shaped structure with unequal lengths of the upper and lower conical surfaces, and the lower end taper is consistent with a section of conical tube 402. This streamlined design allows it to penetrate deep into the low-pressure zone at the center of the swirling flow field, accurately extracting the separated purified liquid. At the same time, its outer surface has low resistance when in contact with the swirling medium, without affecting the stability of the main swirling flow field.

[0042] During the purification process, the outward-curving outer ring 8021 and the inward-curving inner ring 8022 at the lower end of the separating extension pipette 802 form a special reflux channel. This channel gradually expands from top to bottom, allowing trace amounts of heavy particles mixed into the purification liquid due to disturbance during the purification process to slide down the inner wall of the separating extension pipette 802 under the action of centrifugal force and gravity, and slide out through this channel. The sliding direction is consistent with the swirling path of the medium in a section of the cone 402, achieving secondary separation and effectively ensuring the purity of the extracted purification liquid. The purification liquid entering the columnar section of the purification liquid lifting conduit 8 is further lifted by the active lifting frame 10. The lifting motor 1001 drives the lifting shaft 1002 to rotate, and the edge of the lifting screw 1004 on the lifting shaft 1002 is tangential to the inner cavity of the conduit, forming a forced upward spiral pushing force, which significantly improves the lifting efficiency and head of the purification liquid. The lower end of the lifting shaft 1002 is hollow and open. The spirally distributed water outlet holes 1031 and the guide fins 1032 on the diversion cone 1003 form a special diversion structure, which allows a small portion of the light medium to rise directly from the hollow shaft and be thrown out by rotation, while most of the medium is lifted by the lifting screw 1004. This diversion design balances the pressure distribution during the lifting process and reduces energy loss.

[0043] The secondary anti-winding mechanism in the sludge collection pipe 6 is crucial for ensuring the purity of the discharged sludge. The upper anti-winding ring 601 adopts a truncated cone structure that is narrower at the top and wider at the bottom, connecting to the lowest point of the sludge collection bottom plate 104. It maintains a gap of 0.10 to 0.15 meters with the lower end of the second-stage cone 403. This structure effectively prevents the vortex at the center of the swirling flow field from directly entraining the sediment at the bottom, avoiding disturbance to the swirling flow field during sludge discharge. The unidirectional settling plate 602 installed at the upper end of the inner cavity of the sludge collection pipe 6 has a triangular blade structure that is narrower at the top and wider at the bottom, and is evenly distributed vertically. This design ensures that the sediment can only settle downwards in one direction, preventing sludge back-mixing caused by pressure fluctuations or water flow disturbances within the pipe. The sequential gate valve 603 system uses two gates 606 connected by a Z-shaped interlocking element 605 and controlled by a sequential cylinder 604. When the piston rod extends, the lower gate valve opens to discharge sludge, while the upper gate valve closes simultaneously to cut off the flow. This alternating opening and closing method ensures that there is always isolation between the inner cavity of the cyclone separator 4 and the sludge collection pipe 6 during the sludge discharge process, avoiding direct media flow and achieving continuous and stable discharge of high-concentration copper powder precipitates without interrupting the overall treatment process. The clean liquid discharge pipe 301 in the lower middle part of the side wall of the clean liquid tank 3 is lower than the lower end of the inlet pipe 5, ensuring that the clean liquid has sufficient residence time in the tank to further allow residual particles to settle naturally, ultimately discharging high-quality clean liquid.

[0044] Working Principle: During operation, the copper-containing mixture to be treated is first introduced through the inlet pipe 5, and then sprayed into the inner cavity of the cyclone separator 4 via the tangential bend 501 in a downward-sloping direction tangential to the inner wall of the first-stage cone 402. Guided by the horizontal deflection of 30° to 60° and the downward vertical tilt of 15° to 45° by the tangential bend 501, the mixture forms a high-speed rotating external swirling flow field along the inner wall of the first-stage cone 402. At this time, the spirally downward-sloping guide vanes 4021 on the inner wall of the first-stage cone 402 guide the mixture, increasing the probability of collision between particles and the wall surface. This causes the denser copper powder and other heavy phase media to aggregate towards the cone wall under centrifugal force and spiral downwards along the cone wall. As the swirling liquid flows through the first-stage cone 402 and the second-stage cone 403, whose taper gradually increases, the axial component of the swirling velocity gradually increases, thus enhancing the solid-liquid separation effect. The heavy phase medium eventually flows down to the bottom plate 104 of the sedimentation tank 1, while the light liquid forms an upward-flowing internal vortex at the center of the vortex field.

[0045] During the cyclone separation process, the purified liquid lifting system is activated simultaneously. The separation motor 901 in the separation drive seat 9 drives the worm wheel 804 to rotate via the worm gear 902, which in turn drives the purified liquid lifting conduit 8 to rotate smoothly within the fixed sleeve 702. The auxiliary cyclone vanes 801 on the outer wall of the purified liquid lifting conduit 8 rotate with it, and their spiral direction is opposite to the water inlet direction of the inlet pipe 5. This accelerates and pushes the high-viscosity medium near the tangential bend 501 downwards, enhancing the external cyclone intensity and preventing high-concentration slurry from stagnating in the separation zone. At the same time, the shuttle-shaped separation extension pipe 802 at the lower end of the purified liquid lifting conduit 8 penetrates deep into the low-pressure zone at the center of the cyclone field to accurately extract the separated purified liquid. The outer reflux ring 8021 and the inner reflux ring 8022 at the lower end of the separation extension pipette 802 form a reflux channel that gradually expands from top to bottom. During the upward lifting of the purified liquid, trace heavy particles mixed in due to disturbance slide down the inner wall of the separation extension pipette 802 under the action of centrifugal force and gravity, and slide out of this channel. The sliding direction is consistent with the swirling path in a section of the cone 402, realizing secondary separation and effectively ensuring the purity of the extracted purified liquid.

[0046] The purified liquid entering the columnar section of the purified liquid lifting conduit 8 is further lifted by the active lifting frame 10. The lifting motor 1001 drives the lifting shaft 1002 to rotate. The edge of the lifting screw 1004 on the lifting shaft 1002 is tangential to the inner cavity of the columnar end of the purified liquid lifting conduit 8, forming a forced upward spiral pushing force, which significantly improves the lifting efficiency and head of the purified liquid. The lower end of the lifting shaft 1002 is hollow and open. The spirally distributed water outlet holes 1031 and the guide fins 1032 on the diversion cone 1003 work together to allow a small portion of the light medium to rise directly from the hollow shaft and be thrown out of the water outlet holes 1031 through rotation, while most of the medium is lifted upward by the lifting screw 1004. This diversion design balances the pressure distribution during the lifting process and reduces energy loss. After the purified liquid is lifted to the upper end of the purified liquid lifting conduit 8, it overflows through the outward and downward inclined overflow bevel 803 and enters the upper space of the sedimentation tank 1.

[0047] The settling plates 101 fixed on the four side walls of the inner cavity of the settling tank 1 have a sloping structure that slopes towards the center and a downward-inward cut at the top. This allows residual microparticles in the rising purified liquid to slide off the sloping surface as it flows through, preventing solids from adhering to the side walls. The sloping structure also effectively expands the settling area, enhancing the natural settling effect. As the purified liquid continues to rise, the turbulence at the outlet of the cyclone separator 4 is effectively isolated by the blocking and guiding effect of the vertical baffle 102, ensuring that only the surface clarified water can pass over the lower end of the baffle 102 and flow smoothly into the purified liquid tank 3 through the overflow port 103. The purified liquid discharge pipe 301 in the lower part of the side wall of the purified liquid tank 3 is lower than the lower end of the inlet pipe 5, ensuring that the purified liquid has sufficient residence time in the tank for further natural settling of residual particles before finally discharging high-quality purified liquid.

[0048] Guided by the 5° to 10° conical structure of the bottom plate 104, the heavy phase medium concentrates towards the lowest point of the collection pipe 6. The anti-winding ring 601 at the upper end of the collection pipe 6 adopts a truncated cone structure that is narrow at the top and wide at the bottom, maintaining a gap of 0.10 to 0.15 meters between it and the lower end of the two-section cone 403. This effectively prevents the vortex at the center of the swirling flow field from directly entraining the sediment at the bottom, thus avoiding disturbance to the swirling flow field during sludge discharge. After the sediment enters the collection pipe 6, the unidirectional settling plates 602, which are vertically spaced evenly at the upper end of the inner cavity, have a triangular blade structure that is narrow at the top and wide at the bottom. This ensures that the sediment can only settle downwards in one direction, preventing sludge back-mixing caused by pressure fluctuations or water flow disturbances within the pipe. During sludge discharge, the timing cylinder 604 actuates. Since the upper and lower gates 606 are fixedly connected by a Z-shaped interlocking element 605, when the piston rod extends, the lower timing gate valve 603 opens, while the upper timing gate valve 603 simultaneously closes to cut off the flow. This alternating opening and closing method ensures that the inner cavity of the cyclone separator 4 and the sludge collection pipe 6 remain isolated during sludge discharge, preventing direct media flow and achieving continuous and stable discharge of high-concentration copper powder precipitates without interrupting the overall treatment process. The controller 2 coordinates the timing actions of the aforementioned components to achieve automated control of the entire cyclone sedimentation and sludge discharge process.
