Description

A defluorination purification device for non-ferrous metal hydrometallurgy

Technical Field

The invention relates to the technical field of defluorination and purification in metal smelting, in particular to a defluorination and purification device for non-ferrous metal hydrometallurgy.

Background Art

A large amount of wastewater is generated during the hydrometallurgical smelting of non-ferrous metals. The fluorine content in these wastewaters is high. If they are discharged without purification, they will pollute the natural environment. Therefore, the wastewater from metal smelting needs to be defluorinated and purified. During defluorination purification, the defluorinating agent is generally thrown directly into the wastewater to react with the wastewater, and then precipitate to the bottom or attach to the reaction product bucket. During the reaction process, the surface of the defluorinating agent will quickly react with fluorine, which will cause the defluorinating agent to not react fully inside, thereby causing a waste of the defluorinating agent. On the other hand, when there are too many reaction products in the wastewater and they are not cleaned up in time, there will be a lot of reaction residues in the water discharged after purification, which will cause the purified water to still not meet the standards.

The technical content disclosed in the Chinese patent document (publication number: CN116477736A, patent name: An integrated defluorination device for automatically controlling defluorination and a defluorination method thereof) is: comprising a defluorination pool and a defluorination assembly, the left end of the defluorination pool is connected to a filter pool through a pipeline, a convex box is arranged on the surface of the defluorination pool, the defluorination assembly is rotatably connected to the inside of the convex box, a transmission gear is meshed on the top of the gear frame, and a fluorine ion analyzer is arranged on the surface of the defluorination pool. In the integrated defluorination device for automatically controlling defluorination and a defluorination method thereof, the reaction product bucket is embedded in the gear frame, and the gear frame is evenly arranged in the defluorination pool, which is conducive to treating the fluorine in the water body multiple times. After any reaction product bucket is saturated, the transmission gear is driven by the driving motor to rotate the gear frame, so that the unused reaction product bucket is replaced with the saturated reaction product bucket. During the replacement process, the water body keeps flowing, so there is no need to stop the defluorination work, which is conducive to uninterrupted defluorination.

From the above implementation scheme, it can be seen that the defluorination device uses a reaction product bucket to react with wastewater in water, and then uses a fluorine ion analyzer to detect the purified water. When the purified water is detected to be unqualified, the reaction product bucket is cleaned. This method will cause inconsistent quality of purified water in different time periods, thereby affecting the overall water purification effect.

One end of the screw 1041 is connected to the feeding motor 103, and the other end of the screw 1041 extends to the outlet of the spiral feeding barrel 104. After the defluorinating agent falls into the spiral feeding barrel 104, the screw 1041 transports it to the outlet of the spiral feeding barrel 104 in batches, so that the defluorinating agent can be sprinkled into the mixing component 3 in batches to avoid sprinkling too much defluorinating agent at one time and causing the defluorinating agent to clump when it encounters water.

The mixing component 3 includes a mixing cylinder 303, a defluorinating agent inlet 3031 and a diluent inlet 3032 are arranged above one end of the mixing cylinder 303, and a defluorinating liquid outlet 3033 is arranged below the other end of the mixing cylinder 303; the spreading mechanism 2 is connected to one end of the mixing cylinder 303 close to the defluorinating agent inlet 3031, the spreading mechanism 2 includes a spreading motor 201, the spreading motor 201 is connected to a throwing component 202, the throwing component 202 includes a throwing shaft 2021, and the throwing shaft 2021 is circumferentially provided with at least one radiation rod 2022, when the throwing shaft 2021 rotates, the radiation rod 2022 blocks the defluorinating agent inlet 3031 and the diluent inlet 3032 directly below, so that the defluorinating agent and the diluent will be broken up by the rotating radiation rod 2022 and spread around as soon as they enter the mixing cylinder 303.

The mixing component 3 includes a mixing motor 301, which is connected to a mixing gear box 302, which is connected to a stirring rod 304, on which a stirring spiral blade 3041 and a scattering side rod 3042 are provided; the defluorinating agent and the diluent scattered to the bottom of the mixing cylinder 303 are stirred by the stirring rod 304 and further mixed together; the scattering side rod 3042 is perpendicular to the stirring rod 304 and can break up the agglomerated defluorinating agent.

The defluorination liquid outlet 3033 is connected to the shower head 305 below, and the shower head 305 is connected to the top of the reaction tank 10. The defluorination liquid is sprinkled into the reaction tank 10 through the shower head 305, so that the defluorination liquid can be more quickly integrated into the wastewater, thereby reacting with the wastewater quickly. A wastewater inlet 1001 is provided at one end of the reaction tank 10 close to the shower head 305, and a purified water outlet 1002 is provided at the other end of the reaction tank 10. After the defluorination liquid reacts with the wastewater for a certain period of time, the wastewater inlet 1001 is closed, and the purified water outlet 1002 is opened to discharge the purified water.

The mixing component 3 is connected to the reaction tank 10 below, and a defluorination stirring component 4 is arranged in the reaction tank 10. The defluorination stirring component 4 includes a reaction product scoop 404; two symmetrical arc-shaped scoops 4042 are arranged on both sides of the reaction product scoop 404, and filtering holes 4043 are arranged on the two arc-shaped scoops 4042. The reaction product scoop 404 moves in a circular manner in the vertical direction of the reaction tank 10. When the reaction product scoop 404 moves to the bottom of the reaction tank 10, the reaction product scoop 404 and the bottom of the reaction tank 10 form an angle greater than 60 degrees. In this embodiment, the angle between the reaction product scoop 404 and the bottom of the reaction tank 10 is between 60 degrees and 90 degrees, and the direction of movement of the reaction product scoop 404 is opposite to the direction in which the wastewater enters the reaction tank 10. While the reaction product scoop 404 contacts the wastewater with the maximum area, it can also stir the direction in which the wastewater moves, so that the reaction between the defluorination agent and the wastewater is more complete. When the reaction product scoop 404 moves to the upper part of the reaction tank 10, the plane of the reaction product scoop 404 faces downward and is parallel to the bottom of the reaction tank 10; the wastewater and the defluorination agent After the liquid enters the reaction tank, the water level of the waste water is below the waste conveying assembly 5. In this embodiment, the defluorination liquid reacts with the fluorine in the waste water to generate calcium fluoride. When the chain 402 drives the reaction product bucket 404 to rotate below the water level, since calcium fluoride is difficult to dissolve in water, the calcium fluoride will be passively scooped up by the reaction product bucket 404. When the chain 402 drives the reaction product bucket 404 to rotate above the water level, that is, when it is rotated to above the waste conveying assembly 5, since the reaction product bucket 404 is in an inverted shape, the calcium fluoride is poured out to avoid the calcium fluoride adhering to the periphery of the reaction product bucket 404 due to the mixing of water and calcium fluoride. Therefore, the upper scraping assembly 7 and the lower scraping assembly 8 are provided to scrape off the calcium fluoride adhering to the periphery of the reaction product bucket 404.

When the reaction product scoop 404 moves to the upper part of the reaction tank 10, an upper scraping assembly 7 is arranged above the reaction product scoop 404, and a lower scraping assembly 8 is arranged below the reaction product scoop 404. The upper scraping assembly 7 includes a first scraping component 701 and a second scraping component 702, and the first scraping component 701 and the second scraping component 702 are arranged vertically; the lower scraping assembly 8 includes a U-shaped scraping mounting frame 801, and a plurality of third scraping components 802 are arranged on the U-shaped scraping mounting frame 801; the second scraping component 702 includes a scraping motor 7021, and the scraping motor 7021 is connected to a scraping impeller 7022; the scraping impeller 7022 is a soft brush, The structures of the first scraping component 701, the third scraping component 802 and the waste removing component 9 are consistent with the second scraping component 702. Therefore, when the arc bucket 4042 is inverted on the upper scraping component 7, the soft bristles can reach the inside of the arc bucket 4042 to brush off the calcium fluoride, and when the soft bristles contact the lowest surface parts of the two arc buckets 4042, they can be pressed and bent, so that the soft bristles can brush various shapes of the arc bucket 4042.

When the reaction product scoop 404 moves to the upper part of the reaction tank 10, the first scraping member 701 and the second scraping member 702 scrape the upper surface of the reaction product scoop 404, so that the calcium fluoride attached to the upper surface of the reaction product scoop 404 due to the adhesion of water is scraped off, and the third scraping member 802 scrapes the lower surface of the reaction product scoop 404 and the side of the side column 4033, so that the reacted calcium fluoride attached to the inner concave surface of the reaction product scoop 404 and the inner side surface of the side column 4033 due to the adhesion of water is scraped off.

A waste conveying assembly 5 is provided in the middle of the defluorination stirring assembly 4 . The waste conveying assembly 5 is located directly below the lower scraping assembly 8 , and the scraped calcium fluoride falls onto the waste conveying assembly 5 .

The waste conveying assembly 5 includes a first conveying belt 501 and a second conveying belt 502, wherein the first conveying belt 501 is located above the second conveying belt 502, and the first conveying belt 501 and the second conveying belt 502 are staggered. The end of the second conveying belt 502 away from the first conveying belt 501 is provided with a waste removing assembly 9, and the scraped reaction product is finally sent to the end of the second conveying belt 502 away from the first conveying belt 501 along with the conveyance of the first conveying belt 501 and the second conveying belt 502, and the reaction product is scraped off along with the rotation of the waste removing assembly 9 and the second conveying belt 502. Therefore, the defluorination purification device of this embodiment can not only remove the fluorine ions in the wastewater, but also remove the reaction product in time, thereby ensuring the effect of the reaction.

The defluorination stirring assembly 4 includes a sprocket 401, wherein two sprockets 401 are arranged at the two ends of the bottom of the reaction tank 10, and two sprockets 401 are arranged at the two ends of the upper part of the reaction tank 10, the sprocket 401 is meshed and connected with a chain 402, the chain 402 is arranged in a closed loop, a plurality of defluorination components 403 are arranged on the chain 402, and a reaction product scoop 404 is rotatably connected to the defluorination component 403; the defluorination component 403 is arranged in a form of radiation from the periphery of the chain 402 to the periphery of the chain 402, the defluorination component 403 includes a limiting rotating shaft 4031, the two ends of the limiting rotating shaft 4031 are connected to the side pillars 4033, a limiting strip 4032 is arranged on the limiting rotating shaft 4031, and a limiting rotating shaft 4031 is arranged in the middle of the reaction product scoop 404. The limit bar 4032 is located in the limit rotation groove 4041. A reaction product bucket steering assembly 6 is provided at one end above the defluorination stirring assembly 4. The reaction product bucket steering assembly 6 includes a steering motor 601. The steering motor 601 is connected to a toggle component 602. The toggle component 602 includes a toggle shaft 6021. A plurality of toggle connecting ropes 6022 are connected to the circumference of the toggle shaft 6021. The other end of the toggle connecting rope 6022 is connected to a toggle ball 6023. When the toggle shaft 6021 rotates, the toggle ball 6023 is driven to rotate. The reaction product bucket 404 moves upward from the reaction groove 10 to the toggle component 602. The toggle ball 6023 rotates to just reach one end of the reaction product bucket 404. The reaction product scoop 404 rotates from a state nearly parallel to the side pillar 4033 to a state perpendicular to the side pillar 4033. Due to the existence of the limit bar 4032, after one side of the limit rotation groove 4041 is blocked by the limit bar 4032, the reaction product scoop 404 stops rotating. Therefore, the reaction product scoop 404 can maintain a state perpendicular to the side pillar 4033 to pass through the top of the reaction tank 10. When the reaction product scoop 404 passes through the lower end of the reaction tank 10, the direction of movement of the reaction product scoop 404 is opposite to the flow direction of the water flow. Due to the impact force of the wastewater, the reaction product scoop 404 rotates from a state perpendicular to the side pillar 4033. The shape of the reaction product scoop 404 is changed to a shape nearly parallel to the side pillar 4033. Due to the existence of the limit bar 4032, after one side of the limit rotation groove 4041 is blocked by the limit bar 4032, the reaction product scoop 404 will stop rotating. Therefore, when the reaction product scoop 404 passes the lower end of the reaction tank 10, it can maintain a shape nearly parallel to the side pillar 4033, and the contact area between the reaction product scoop 404 and the wastewater is increased during the movement, so that calcium fluoride is caught by the arc bucket 4042 before it is precipitated after being generated. Since the filter hole 4043 is provided inside the arc bucket, the water flow can flow away through the filter hole 4043, and the water flow is prevented from washing away the calcium fluoride caught by the arc bucket 4042.
