Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a graded treatment device for mixed wastewater in industrial parks. Background Technology

[0002] Comprehensive industrial parks often integrate various industries such as chemical, electroplating, printing and dyeing, pharmaceutical, and machinery processing. The wastewater discharged contains not only conventional pollutants such as COD, ammonia nitrogen, and petroleum hydrocarbons, but also characteristic pollutants such as heavy metals, cyanides, recalcitrant organic matter, and high salinity. The water quality and quantity fluctuate greatly, the composition is complex, and the toxicity is high. The general treatment method for mixed wastewater is as follows: first, large particulate suspended solids and water quality and quantity are removed and adjusted by screening and equalization tanks; then, some suspended solids and organic matter are removed by primary sedimentation tanks; next, organic matter and nitrogen and phosphorus nutrients are removed by biological reactors; then, sludge and water are separated by secondary sedimentation tanks; finally, advanced treatment is carried out to ensure that the effluent meets the standards. However, sedimentation tanks require a large area to settle flocs, and the sediment is difficult to clean. Therefore, we propose a graded treatment device for mixed wastewater in industrial parks.

This is a graded treatment device for mixed wastewater in an industrial park. Wastewater is added to the inner side of a mixing tank, followed by the addition of flocculant. The wastewater is stirred by blades to ensure thorough mixing of the flocculant and wastewater. Then, a stop valve is opened, and the mixed wastewater is diverted to the inner side of a sedimentation tank via a water inlet pipe. Branch pipes then divert the wastewater to ash collection plates. The staggered ash collection plates allow sediment in the wastewater to settle on the plates. Baffles slow down the water flow and isolate the sediment, ensuring thorough settling. The device has a small footprint, is easily movable, and a push shaft pulls the baffles to adhere tightly to the ash collection plates, preventing wastewater leakage.

A partition 22 is fixedly connected to the inner side of the stirring tank 21. The cleaning device 3 includes a sedimentation tank 31 fixedly installed inside the support frame 1. A drinking water component 32 is arranged inside the sedimentation tank 31 to guide the wastewater inside the stirring tank 21 to the upper end of the sedimentation tank 31. Two sets of sedimentation devices 33 are arranged below the drinking water component 32 to settle the flocculated flocculation in the wastewater.

[0020] In this embodiment, a crossbeam 23 is fixedly connected to the upper end of the mixing tank 21, and two sets of first motors 24 are installed on the upper end of the crossbeam 23. A stirring rod 25 is fixedly connected to the output end of the first motor 24, and blades 26 are provided on the outer side of the stirring rod 25. The bottom end of the inner wall of the mixing tank 21 is a slope.

[0021] Specifically, wastewater is added to the inside of the mixing tank 21, and then flocculant is added. The blades 26 are used to stir the wastewater to ensure that the flocculant and wastewater are fully mixed.

[0022] In this embodiment, the drinking water assembly 32 includes two sets of mounting plates 321 fixedly connected to the upper end of the sedimentation tank 31. The inner sides of the two sets of mounting plates 321 are fixedly connected to a water inlet pipe 322. The upper end of the water inlet pipe 322 is fixedly connected to the stirring tank 21. A water stop valve 323 is provided at the connection between the water inlet pipe 322 and the stirring tank 21. Multiple sets of branch pipes 324 are provided on the outer side of the water inlet pipe 322.

[0023] Specifically, the stop valve 323 is opened and the mixed wastewater is diverted to the inside of the sedimentation tank 31 through the water inlet pipe 322, and the wastewater is diverted to the ash collection plate 333 through the branch pipe 324.

[0024] In this embodiment, the sedimentation device 33 includes two sets of horizontal plates 331 fixedly connected to the inner side of the sedimentation tank 31. The lower end of the horizontal plates 331 is fixedly connected to a fixing plate 332. Two sets of ash collection plates 333 are rotatably connected to the opposite side of the two sets of fixing plates 332. The ash collection plates 333 are staggered from each other. The inner side of the ash collection plates 333 is movably connected to a baffle 334. The front ends of several sets of ash collection plates 333 are jointly provided with an adjustment component 35 for adjusting the angle of the ash collection plates 333.

[0025] Specifically, the wastewater sediment is settled on the interlocking ash collection plates 333, and the baffles 334 slow down the water flow and isolate the sediment, ensuring that the sediment can settle completely. In this embodiment, a push shaft 337 is fixedly connected to the lower end of the baffle 334, and a top plate 335 is fixedly connected to the lower ends of multiple sets of push shafts 337. A spring 338 is provided on the outer side of the push shaft 337, and the lower end of the spring 338 is fixedly connected to the top plate 335. The upper end of the spring 338 is fixedly connected to the lower end of the dust collection plate 333. A top plate 336 is slidably connected to the inner side of the fixing plate 332. The top plate 336 is L-shaped and is located below the top plate 335.

[0026] Specifically, the push shaft 337 can be used to pull the baffle 334 to fit tightly against the ash collection plate 333 to prevent wastewater leakage. After adjusting the ash collection plate 333 to a certain angle, the top plate 336 is used to hold the top plate 335 in place. The ash collection plate 333 is then adjusted to rotate downwards, and the baffle 334 separates from the ash collection plate 333. At this time, clean water can be used to rinse the sedimentation device 33.

[0027] In this embodiment, a vibration assembly 34 for pushing the top plate 336 to move is provided on the inner side of the sedimentation tank 31. The vibration assembly 34 includes a main rod 347, a bottom rod 348 is fixedly connected to the lower end of the main rod 347, and two sets of support rods 349 are fixedly connected to the upper end of the bottom rod 348. The support rods 349 are fixedly connected to the main rod 347 and the adjacent top plate 336. A cleaning brush 3410 is installed at the lower end of the bottom rod 348.

[0028] The rear end of the mounting plate 321 is fixedly connected to a second motor 341 and a fixing frame 342. The lower end of the fixing frame 342 is rotatably connected to a rotating shaft 343. The rotating shaft 343 is fixedly connected to the output shaft of the second motor 341. The rear end of the rotating shaft 343 is fixedly connected to a turntable 344. The rear end of the turntable 344 is fixedly connected to an eccentric block 345. The outer side of the eccentric block 345 is rotatably connected to a swing arm 346. The swing arm 346 is rotatably connected to the main rod 347.

[0029] Specifically, the second motor 341 drives the rotating shaft 343 to rotate, which in turn drives the turntable 344 to rotate. The eccentric block 345 drives the swing arm 346 to rotate while pushing the main rod 347 to move back and forth. Then, the cleaning brush 3410 cleans the bottom of the inner wall of the sedimentation tank 31. Then, the support rod 349 drives the top plate 336 to move back and forth, pushing the top plate 335 to move up and down, causing the ash accumulation plate 333 to vibrate and accelerate the cleaning of the sediment.

[0030] In this embodiment, the adjustment component 35 includes a crossbar 351 fixedly connected between two sets of cross plates 331. A rotating rod 352 is rotatably connected to the inner side of the crossbar 351. Two sets of threaded posts 353 are provided on the rotating rod 352. A threaded ring 354 is threadedly connected to the outer side of the rotating rod 352. Two sets of connecting blocks 355 are fixedly connected to the outer side of the threaded ring 354. A push rod 356 is fixedly connected to one side of the connecting block 355. A connecting shaft 357 is rotatably connected to the inner side of the push rod 356. The connecting shaft 357 is fixedly connected to its adjacent dust accumulation plate 333. A rotating cap 358 is fixedly connected to the upper end of the rotating rod 352.

[0031] Specifically, the rotating cap 358 can drive the rotating rod 352 to rotate, which in turn drives the threaded ring 354 to slide on the outside of the threaded post 353. The threaded ring 354 drives the connecting block 355 to move. The push rod 356 presses the connecting shaft 357 to make the ash collection plate 333 rotate on the inside of the fixed plate 332, adjusting the angle of the ash collection plate 333, thereby adjusting the water flow rate and facilitating the deposition of flocculants on the surface of the ash collection plate 333.

[0032] In this embodiment, a rotating groove 339 is provided on one side of the dust collection plate 333, and a rotating block 3310 is rotatably connected to the inner side of the rotating groove 339. The rotating block 3310 is fixedly connected to the fixing plate 332.

[0033] Specifically, the rotating block 3310 facilitates the rotation of the dust collection plate 333.

[0034] It should be noted that during use, wastewater is added to the inside of the mixing tank 21, followed by the addition of flocculant. The first motor 24 is started, driving the mixing rod 25 to rotate. The blades 26 are used to stir the wastewater. Then, the stop valve 323 is opened, and the mixed wastewater is diverted to the inside of the sedimentation tank 31 via the water inlet pipe 322. The wastewater is then diverted to the ash collection plate 333 via the branch pipe 324. The staggered ash collection plates 333 allow the wastewater sediment to settle on them. The baffle 334 slows down the water flow and isolates the sediment, ensuring that the sediment can settle fully. The push shaft 337 pulls the baffle 334 to press it tightly against the ash collection plate 333 to prevent wastewater leakage. Rotating the rotating cap 358 drives the rotating rod 352 to rotate, which in turn causes the threaded ring 354 to slide on the outside of the threaded column 353. The threaded ring 354 drives the connecting block 355 to move, and the push rod 356 presses the connecting block. Shaft 357 causes the ash collection plate 333 to rotate inside the fixed plate 332, adjusting the angle of the ash collection plate 333 and thus adjusting the water flow rate. Continuing to rotate the rotating cap 358, it presses the ash collection plate 333 downwards, and the top plate 336 holds the top piece 335 in place. At this time, the ash collection plate 333 slides on the push shaft 337, compressing the spring 338. The baffle 334 then separates from the ash collection plate 333, allowing clean water to rinse the sedimentation device 33. The second motor 341 is started, driving the rotating shaft 343 to rotate, which in turn drives the turntable 344 to rotate. The eccentric block 345 drives the swing arm 346 to rotate while simultaneously pushing the main rod 347 back and forth. The cleaning brush 3410 then cleans the bottom of the inner wall of the sedimentation tank 31. Finally, the support rod 349 drives the top plate 336 back and forth, pushing the top piece 335 up and down, causing the ash collection plate 333 to vibrate and accelerating the cleaning of the sediment.
