Description

Technical Field

[0001] This invention relates to the field of rare earth powder production wastewater purification technology, specifically to a rare earth powder production wastewater purification and treatment equipment. Background Technology

[0002] Rare earth powders are micro- and nano-sized powders obtained by calcining, ultrafine grinding, and classification of rare earth compounds. They possess the unique photoelectromagnetic and electromagnetic catalytic properties of rare earths, and their particle size and purity can be controlled as needed. As a key basic raw material, they are widely used in high-end industries such as permanent magnets, luminescence, catalysis, electronic ceramics, and new energy.

[0003] In the current process of purifying wastewater from rare earth powder production, inclined plate sedimentation tanks are typically used for sedimentation treatment. Most of the sludge precipitated from the wastewater accumulates at the bottom of the sedimentation tank. Although the sedimentation tank can clean this sludge through the sludge discharge pipe at the bottom, a large amount of sludge will still remain on the inclined plates. If this sludge is not cleaned in time, it will directly affect the subsequent purification efficiency. In addition, during the purification process, some sludge is pumped out and sent back into the front-end flocculation tank as a flocculation medium for preliminary filtration of the wastewater. However, during the operation of the pump, it is inevitable that the sludge flocs will be torn and broken up, resulting in a decrease in its adsorption effect.

[0004] Based on this, the present invention designs a wastewater purification and treatment device for rare earth powder production to solve the above problems. Summary of the Invention

The sludge discharge end of one end of the annular reflux sludge discharge pipe extends to the top inner side of the end of the chemical mixing tank away from the chemical mixing tank. The other sludge discharge end of the annular reflux sludge discharge pipe is located away from the chemical mixing tank.

The follow-up inclined plate drive component 340 is installed on the top of the translational sludge scraping component 330. By moving the sludge scraping assembly 330, the follower inclined plate drive assembly 340 is moved, which in turn drives the movable inclined plate assembly 320 to move. This allows the angle between the movable inclined plate assembly 320 and the horizontal plane to be adjusted. When cleaning the sludge at the bottom of the return sedimentation assembly 310, the sludge remaining on the movable inclined plate assembly 320 can be cleaned simultaneously, ensuring the purification efficiency of the movable inclined plate assembly 320.

[0022] A flocculation drain pipe 101 is connected through one side of the top of the front flocculation tank 1, a flocculation inlet pipe 102 is connected through the other side of the top of the front flocculation tank 1, and a flocculation sludge discharge pipe 103 is connected through one end of the bottom of the front flocculation tank 1.

[0023] The mid-end dosing reflux mechanism 2 includes a dosing mixing tank 210 and a grid-type dosing assembly 220. The output end of the dosing mixing tank 210 is connected to the front flocculation tank 1, and the grid-type dosing assembly 220 is installed inside the dosing mixing tank 210.

[0024] The bottom of the dosing mixing tank 210 is connected to a dosing and sludge discharge pipe 211. The dosing and sludge discharge pipe 211 extends from the end away from the dosing mixing tank 210 to the top inner side of the end of the front flocculation tank 1 away from the flocculation sludge discharge pipe 103. The grid-type dosing assembly 220 includes a horizontal baffle 221, a vertical baffle 222, a horizontal diversion pipe 223, a vertical diversion pipe 224, and a confluence pipe 225. The two horizontal baffles 221 are respectively fixedly connected to the upper and lower ends inside the dosing mixing tank 210. The upper and lower horizontal baffles 221 are close to each other on one side and are evenly spaced and fixedly connected to multiple vertical baffles 222.

The sludge discharge end of one end of the annular reflux sludge discharge pipe 313 extends to the inner side of the top of the end of the chemical mixing tank 210 away from the chemical mixing tank 211. The other sludge discharge end of the annular reflux sludge discharge pipe 313 is located away from the chemical mixing tank 210. By connecting the flocculation drainage pipe 101 to the sedimentation inlet pipe 314 via an external pump, the wastewater that has undergone preliminary flocculation filtration in the upstream flocculation tank 1 can be sent into the sedimentation tank 311 for secondary flocculation and sedimentation. Then, through the annular return sludge discharge pipe 313 at one end of the bottom of the sedimentation tank 311, part of the sludge inside the sedimentation tank 311, along with the wastewater, is sent into the chemical mixing tank 210. This part of the sludge, along with the wastewater, flows along a grid-like flow pattern formed by two horizontal baffles 221 and multiple vertical baffles 222 spaced apart. The flow proceeds through the channel, and simultaneously, through two horizontal diversion pipes 223, the well-mixed chemical solution is sent into the interior of the grid-type flow channel through multiple nozzles on multiple vertical diversion pipes 224 to mix with the sludge, which can further improve the adsorption capacity of the sludge. Then, it flows back into the interior of the front-end flocculation tank 1 through the chemical dosing and sludge discharge pipe 211, so that the sludge mixed with the chemical solution can be used as a flocculation medium to mix with the wastewater in the front-end flocculation tank 1, and perform preliminary flocculation filtration, which can improve the wastewater purification efficiency.

[0026] The movable inclined plate assembly 320 includes an inclined plate mounting frame 321, an inclined plate 322, an inclined plate lifting frame 323, and a sliding rod 324. The inclined plate mounting frame 321 is fixedly connected to the inside of the sedimentation tank 311. The bottoms of the multiple inclined plates 322 are rotatably connected to the inclined plate mounting frame 321 at even intervals. The tops of the multiple inclined plates 322 are rotatably connected to the inclined plate lifting frame 323 at even intervals. The two sliding rods 324 are fixedly connected to the top two ends of the inclined plate lifting frame 323.

[0027] The translational sludge scraping assembly 330 includes a translational linear module 331, a translational mounting frame 332, a mounting rod 333, and a toothed scraper 334. The bottoms of the two translational linear modules 331 are respectively fixedly connected to the top ends of the sedimentation tank 311. The bottoms of the two translational mounting frames 332 are respectively fixedly connected to the output ends of the two translational linear modules 331. The tops of the two mounting rods 333 are respectively fixedly connected to the two translational mounting frames 332. The bottoms of the two mounting rods 333 are fixedly connected to the toothed scraper 334, and the bottoms of the toothed scraper 334 are respectively attached to multiple sedimentation cone plates 312.

[0028] The follow-up inclined plate drive assembly 340 includes a trapezoidal sliding plate 341, a roller assembly 342, roller guide rods 343, and an I-shaped lifting plate 344. The bottoms of the two trapezoidal sliding plates 341 are respectively fixedly connected to the top ends of the sedimentation tank 311, and the two trapezoidal sliding plates 341 are respectively located outside the two translational linear modules 331. The top of each trapezoidal sliding plate 341 has a trapezoidal groove 345 along the trapezoidal side. The bottoms of the roller assembly 342 are rotatably connected to the inside of the trapezoidal groove 345. The bottoms of the two roller guide rods 343 are respectively fixedly connected to the top ends of the roller assembly 342. The top of rod 343 is vertically slidably connected to both sides of one end of the translation mounting bracket 332. The I-shaped lifting plate 344 has two symmetrical guide rod grooves 346 at both ends. The I-shaped lifting plate 344 has two symmetrical sliding rod grooves 347 between the two guide rod grooves 346 at both ends. The two sliding rod grooves 347 are respectively perpendicular to the two guide rod grooves 346. The I-shaped lifting plate 344 is horizontally slidably connected to the top of the two roller guide rods 343 through the guide rod grooves 346. The I-shaped lifting plate 344 is horizontally slidably connected to the sliding rod 324 through the sliding rod grooves 347. After the wastewater undergoes preliminary flocculation and filtration in the pre-flocculation tank 1, it is pumped into the sedimentation tank 311 by an external pump. Chemicals are added to the sedimentation tank 311 to further flocculate and settle the wastewater. When a large amount of sludge is generated and needs to be cleaned, an external controller controls two linear translation modules 331 to work synchronously, thereby moving two translation mounting frames 332 synchronously. The two translation mounting frames 332 move the toothed scrapers 334 at the bottom of the two mounting rods 333 along the surfaces of multiple sedimentation cone plates 312, sending the sludge from the sedimentation tank 311 into the annular return sludge discharge pipe 313. Simultaneously, the two translation mounting frames 332 move the two roller groups 342 at the bottom of multiple roller guide rods 343, causing the two roller groups 342 to move along two ladders... The trapezoidal groove 345 on the sliding plate 341 rolls, and the two roller groups 342 roll inside the trapezoidal groove 345. During this process, multiple roller guide rods 343 slide along the guide rod groove 346 on the I-shaped lifting plate 344, which drives the I-shaped lifting plate 344 to rise and fall. In this process, the I-shaped lifting plate 344 drives two slide rods 324 to slide and rise and fall through the two slide rod grooves 347 at both ends. This causes the two slide rods 324 to drive the inclined plate lifting frame 323 to rise and fall. The inclined plate lifting frame 323 drives multiple inclined plates 322 to rotate around the bottom inclined plate mounting frame 321, which can adjust the angle of multiple inclined plates 322 with the horizontal plane. This makes it easier to pour the sludge attached to them into the bottom of the sedimentation tank 311 by gravity, and avoid the residual sludge on the inclined plates 322 from affecting its purification efficiency.
