Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a highly efficient chemical wastewater treatment system. Background Technology

[0002] With the production of chemical products, chemical enterprises generate a large amount of heavily polluting wastewater. Chemical wastewater has a complex composition and high pollution concentration, requiring treatment. For example, coal chemical wastewater is a high-concentration organic wastewater with extremely complex pollutant composition and many recalcitrant substances.

[0003] In coal chemical industry, common oil removal processes include gravity oil separation, air flotation oil removal, and adsorption oil removal. However, after the primary gravity oil separation process, most of the heavy oil is separated, and the remaining oil is mostly emulsified oil. Emulsified oil tends to float on the surface of wastewater, causing a large amount of oil to enter the next industrial treatment step with the wastewater, which is not conducive to improving wastewater treatment efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problem mentioned in the background art above, where emulsified oil tends to float on the surface of wastewater, causing a large amount of oil to enter the next industrial treatment step along with the wastewater, which is not conducive to improving wastewater treatment efficiency.

The treatment tank includes a flow tank, an adsorption tank, and an isolation tank. The output end of the inlet pipe is located in the flow tank. The oil removal mechanism includes a floating component and a squeezing component floating in the adsorption tank. The floating component is used to adsorb oil entering the adsorption tank. The squeezing component includes a squeezing roller and a lifting plate. The lifting plate is located below the floating component, and the squeezing roller is located above the floating component. An oil collection shell is fixed on one side of the adsorption tank, and an oil outlet pipe is installed on the oil collection shell.

[0006] Preferably, the floating component includes a water-resistant foam frame and an oil-absorbing sponge, wherein the oil-absorbing sponge is fixed to the water-resistant foam frame, and the water-resistant foam frame enables the oil-absorbing sponge to float stably.

[0007] Preferably, the inlet end of the adsorption tank has an inclined plate, and the water from the flow tank overflows the inclined plate and enters the adsorption tank. Side plates extend upward on both sides of the lifting plate, and the upper ends of the two side plates are higher than the floating member. A through groove is opened on the side plate facing the inclined plate. The two side plates are connected by a lifting frame. The inclined plate can make the fluctuation amplitude of the wastewater small.

[0008] Preferably, the degreasing mechanism further includes a motor, the output end of which is fixed with a drive rod, and the drive rod is connected to a transmission component one and a transmission component two. The transmission component one is used for the lifting plate to rise, and the transmission component two is used for the extrusion roller to roll.

[0009] Preferably, the transmission component one includes a slide rail, a drive gear, and a fixed frame. The drive gear is fixedly connected to a drive rod. A toothed plate transmission component meshes with the lower side of the drive gear. A toothed plate is fixedly connected to the toothed plate transmission component. Both the toothed plate transmission component and the toothed plate are slidably connected to the slide rail. A baffle is fixed on the slide rail. A speed-increasing gear set meshes with the toothed plate. A transmission rod is rotatably connected to the fixed frame. The speed-increasing gear set and the transmission rod are connected via a transmission belt pulley assembly. A threaded rod passing through the fixed frame is fixed on the lifting frame. A limiting post passing through the fixed frame is fixed on the lifting frame. A bevel gear is fixedly connected to the end of the transmission rod. A bevel gear is rotatably connected to the fixed frame. The bevel gear is threadedly connected to the threaded rod, and the bevel gear meshes with the bevel gear.

[0010] Preferably, the transmission component two includes a toothed plate two, one side of which has an extension plate. A transmission gear is fixedly connected to the shaft of the extrusion roller. A limit block is slidably connected to the extension plate. The shaft of the extrusion roller passes through the limit block. A threaded rod two is rotatably connected to the extension plate. The two threaded rods two are connected by a synchronous belt pulley assembly. Two synchronous blocks are fixed to the end face of the threaded rod two. Two synchronous plates are fixed to the end face of the drive rod. The two sides of the synchronous plates are in contact with the two synchronous blocks respectively.

[0011] Preferably, a squeezing block is provided on one side of the squeezing roller. The squeezing block has an arc-shaped surface and compensates for the oil-absorbing sponge that the squeezing roller cannot squeeze.

[0012] Preferably, a rod is fixed to the lower surface of the extrusion block, and the rod passes through the waterproof foam frame and the lifting plate.

[0013] Preferably, a rubber strip is installed on the oil collecting shell, and the rubber strip extends into the adsorption tank, which facilitates the entry of oil into the oil collecting shell.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The oil-absorbing sponge in the floating component can effectively absorb the oil entering the adsorption tank, and can specifically treat oil pollutants in chemical wastewater, improve oil removal efficiency. The rolling of the squeeze roller helps to protect the floating component and makes the oil in the oil-absorbing sponge more fluid, so that the oil in the oil-absorbing sponge can be squeezed out more fully. The inclined rubber strip on the oil collection shell can effectively prevent the oil from dripping back into the adsorption tank. An inclined plate is installed at the inlet of the adsorption tank. Wastewater that overflows the inclined plate flows into the adsorption tank along the inclined surface, which can reduce the fluctuation of the wastewater, which is conducive to the oil-absorbing sponge adsorbing oil. At the same time, it also ensures the stability of the wastewater treatment process and reduces the impact of water flow fluctuation on the oil removal effect. The oil removal mechanism and the inclined plate work together to ensure that the adsorption tank does not interrupt the flow of wastewater, thus guaranteeing the continuity of wastewater treatment. This helps to improve the overall wastewater treatment efficiency and avoids the problem of reduced treatment efficiency caused by wastewater interruption. Attached Figure Description

[0037] Please see Figure 1 - Figure 15 A high-efficiency chemical wastewater treatment system includes: a treatment tank 1, an inlet pipe 2, and an oil removal mechanism 3. The treatment tank 1 includes a flow tank 11, an adsorption tank 12, and an isolation tank 13. A connecting channel 14 is provided between the adsorption tank 12 and the isolation tank 13. The bottom of the isolation tank 13 is at the same height as the bottom of the channel 14. The inlet pipe 2 is located on one side of the treatment tank 1 and inputs wastewater into the flow tank 11. The inlet pipe 2 is connected to the upper side of a second regulating tank 53. The inlet end of the adsorption tank 12 has an inclined plate 15. Water from the flow tank 11 overflows the inclined plate 15 and enters the adsorption tank 12. The height of the wastewater flowing out of the isolation tank 13 is within the longitudinal height range of the inclined plate 15, and the wastewater flowing out of the isolation tank 13 enters an outlet tank 4.

[0038] A sealing plate 16 is installed in the closed channel 14 within the adsorption tank 12. A float 17 is fixed to the upper end of the sealing plate 16, and a lifting foam 18 is fixed to the lower surface of the float 17. The lifting foam 18 is located above the channel 14, preventing oil from entering the channel 14. Guide rods 19 are provided at both ends of the float 17, and limit rings 191 are fixed to the top of the guide rods 19. Wastewater enters the flow tank 11 through the input pipe 2, then overflows the inclined plate 15 and enters the adsorption tank 12. The wastewater in the adsorption tank 12 slowly rises, first overflowing the channel 14, then contacting the lifting foam 18. As the wastewater continues to rise, the lifting foam 18 and the float 17 float upwards. The float 17 carries the sealing plate 16 upwards, causing the channel to... Channel 14 is opened, and wastewater enters the isolation tank 13 through channel 14. The float 17 descends. When the water level in the isolation tank 13 is the same as that in the adsorption tank 12, channel 14 remains connected to the adsorption tank 12 and the isolation tank 13. Then, the water levels in the isolation tank 13 and the adsorption tank 12 rise together. The rising foam 18 and the float 17 continue to rise until the float 17 contacts the limiting ring 191 and stops. The water level continues to rise, and then the wastewater overflows the float 17 and continues to rise. When the wastewater rises to a level where it can flow out of the isolation tank 13, the water level remains stable. At this time, the water level is within the longitudinal height range of the inclined plate 15. During the rise of the water level in the adsorption tank 12, the wastewater first contacts the lifting plate 322 and then contacts the floating component 31. The wastewater overflowing the inclined plate 15 flows into the adsorption tank 12 along the inclined surface of the inclined plate 15, resulting in small fluctuations in the wastewater, which is beneficial for the stable adsorption of oil by the oil-absorbing sponge 312.

[0039] An equalization tank 5 is located upstream of treatment tank 1. The equalization tank 5 includes a first equalization trough 51, a conversion trough 52, and a second equalization trough 53. Wastewater from the first equalization trough 51 flows into the conversion trough 52 from above, and wastewater from the conversion trough 52 flows into the second equalization trough 53 through a pipe. An input component 6 is located upstream of the first equalization trough 51, and the input component 6 pumps wastewater into the first equalization trough 51. Multiple dosing devices 7 are located outside the first equalization trough 51, and the dosing devices 7 add chemicals to the first equalization trough 51, the second equalization trough 53, and the outflow tank 4 through pipes. Sedimentation discharge devices 8 are connected to the bottom of the first equalization trough 51 and the second equalization trough 53, and a water suction device 9 is connected to the bottom of the outflow tank 4.

[0040] The output end of the input pipe 2 is located inside the flow cell 11, and the inlet end of the input pipe 2 is connected to the second regulating tank 53. The oil removal mechanism 3 includes a floating component 31 and a squeezing component 32 floating in the adsorption tank 12. The floating component 31 is used to adsorb the oil entering the adsorption tank 12. The floating component 31 includes a water-proof foam frame 311 and an oil-absorbing sponge 312. The oil-absorbing sponge 312 is fixed to the water-proof foam frame 311. The end of the water-proof foam frame 311 facing the oil collection shell 33 has an opening to facilitate the outflow of oil. The bottom of the water-proof foam frame 311 is provided with multiple thin plates 313 for supporting the oil-absorbing sponge 312. The thin plates 313 do not affect the rolling of the squeezing roller 321.

[0041] The extrusion component 32 includes an extrusion roller 321 and a lifting plate 322. The lifting plate 322 is located below the floating component 31, and the extrusion roller 321 is located above the floating component 31. An oil collection shell 33 is fixed on one side of the adsorption tank 12. An oil outlet pipe 34 is installed on the oil collection shell 33. The bottom of the oil collection shell 33 is inclined to facilitate the flow of oil to the oil outlet pipe 34. The oil outlet pipe 34 is connected to a collection bucket, which is not shown in the figure.

[0042] Side plates 323 extend upwards from both sides of the lifting plate 322. The upper ends of the two side plates 323 are higher than the float 31. The side plate 323 facing the inclined plate 15 has a through groove 324, which facilitates the entry of oil between the two side plates 323. After the lifting plate 322 rises, the two side plates 323 allow the float 31 to land stably on the lifting plate 322. The two side plates 323 are connected by a lifting frame 325.

[0043] The oil removal mechanism 3 also includes a motor 35, which is installed inside the oil collection shell 33. The output end of the motor 35 is fixed with a drive rod 36. The drive rod 36 is connected to a transmission component 37 and a transmission component 38. The transmission component 37 is used to raise the lifting plate 322, and the transmission component 38 is used to roll the extrusion roller 321. The oil removal mechanism 3 and the inclined plate 15 work together to ensure that the adsorption tank 12 does not interrupt the flow of wastewater, which is beneficial to the wastewater treatment efficiency.

[0044] Transmission component 37 includes a slide rail 371, a drive gear 372, and a fixed frame 373. The slide rail 371 is fixedly connected to the oil collection shell 33, the drive gear 372 is fixedly connected to the drive rod 36, one end of the fixed frame 373 is fixed to the adsorption tank 12, and the other end of the fixed frame 373 is fixed to the slide rail 371. A toothed transmission component 374 meshes with the lower side of the drive gear 372. The toothed transmission component 374 includes a fixed toothed plate and movable teeth at both ends. The movable teeth are connected by a rod. The body and spring are connected to the toothed plate. The toothed plate transmission component 374 is an existing transmission component. A toothed plate 375 is fixedly connected to the toothed plate transmission component 374. Both the toothed plate transmission component 374 and the toothed plate 375 are slidably connected to the slide rail 371. A baffle 376 is fixed on the slide rail 371. Two baffles 376 are provided. One baffle 376 is used to block the toothed plate 375, and the other baffle 376 is used to block the toothed plate transmission component 374. The two baffles 376 are used for the movement of the toothed plate transmission component 374 and the toothed plate 375. A speed-increasing gear set 377 is meshed on the toothed plate 375. The speed-increasing gear set 377 is composed of multiple gears of different diameters. A transmission rod 378 is rotatably connected to the fixed frame 373. The speed-increasing gear set 377 and the transmission rod 378 are connected by a transmission pulley assembly 379. The transmission pulley assembly 379 is an existing transmission component and will not be described in detail. A lifting frame 325 is fixed with a gear passing through the fixed frame 373. The threaded rod 3710 is fixed on the lifting frame 325, and a limiting post 3711 passing through the fixed frame 373 is fixed on the fixed frame 373. The fixed frame 373 has a through hole through which the limiting post 3711 and the threaded rod 3710 pass. The end of the transmission rod 378 is fixedly connected to the bevel gear 3712. The fixed frame 373 is rotatably connected to the bevel gear 3713. The bevel gear 3713 is threadedly connected to the threaded rod 3710, and the bevel gear 3712 meshes with the bevel gear 3713.

[0045] A transmission component 38 is provided on each side of the extrusion roller 321. The transmission component 38 includes a toothed plate 381, with an extension plate 382 on one side. The toothed plate 381 and the extension plate 382 are fixedly connected. Both ends of the toothed plate 381 are fixedly connected to the inner wall of the adsorption tank 12 and the oil collection shell 33, respectively. A transmission gear 383 is fixedly connected to the shaft of the extrusion roller 321. A limit block 384 is slidably connected to the extension plate 382. The shaft of the extrusion roller 321 passes through the limit block 384. The rod can rotate on the limiting block 384. A threaded rod 385 is rotatably connected to the extension plate 382. The two threaded rods 385 are connected by a synchronous belt pulley assembly 386. Two synchronous blocks 387 are fixed to the end face of one of the threaded rods 385. Two synchronous plates 388 are fixed to the end face of the drive rod 36. The two sides of the synchronous plates 388 are in contact with the two synchronous blocks 387 respectively. A rotating rod that inserts into the threaded rod 385 is fixed on the drive rod 36. The opposite faces of the two synchronous plates 388 are fixed on the rotating rod.

[0046] A squeezing block 389 is provided on one side of the squeezing roller 321. The squeezing block 389 is fixedly connected to the inner wall of the adsorption tank 12. The squeezing block 389 has an arc-shaped surface that does not contact the squeezing roller 321. After being lifted by the lifting plate 322, the squeezing block 389 presses onto the oil-absorbing sponge 312. The squeezing block 389 compensates for the oil-absorbing sponge 312 that the squeezing roller 321 cannot reach. An insertion rod 3810 is fixed on the lower surface of the squeezing block 389. The insertion rod 3810 passes through the water-proof foam frame 311 and the lifting plate 322. The diameter of the through hole on the water-proof foam frame 311 is larger than the diameter of the insertion rod 3810, so that the oil-absorbing sponge 312 can be raised and lowered stably.

[0047] A rubber strip 3811 is installed on the oil collection shell 33. The rubber strip 3811 extends into the adsorption tank 12. The oil-absorbing sponge 312 does not come into contact with the rubber strip 3811 during the lifting and lowering process. The rubber strip 3811 is also set at an angle, which is conducive to the oil flowing into the oil collection shell 33.

[0048] During use, the output shaft of motor 35 rotates clockwise (e.g., Figure 15 (As shown), motor 35 causes drive rod 36 to rotate, drive rod 36 causes drive gear 372 and synchronous plate 388 to rotate together. Before synchronous plate 388 contacts synchronous block 387, lifting plate 322 has already lifted floating part 31 to the upper side of wastewater and stopped moving. Specifically, drive gear 372 rotates, causing toothed plate transmission component 374 to move. Toothed plate transmission component 374 drives toothed plate 375 to move. Toothed plate 375 causes transmission rod 378 to rotate through speed-increasing gear set 377 and transmission belt pulley assembly 379. Transmission rod 378 causes bevel gear 3712 to rotate. Bevel gear 3712 causes bevel gear 3713 to rotate. Bevel gear 3713 rotates, causing threaded rod 3710 to rise. Threaded rod 3710 causes lifting frame 325, limit post 3711, side plate 323 and lifting plate 322 to rise. As they rise together, the lifting plate 322 lifts the float 31 during the ascent, and the float 31 is located on the lifting plate 322. At this time, the through groove 324 is located on the upper side of the float 31. One end of the lifting plate 322 deforms the rubber strip 3811 during the ascent, and the float 31 will not detach from the insert rod 3810 during the ascent. When the toothed plate transmission component 374 stops moving due to the baffle 376, the lifting plate 322 is already above the rubber strip 3811. The rubber strip 3811 returns to its original position, and a part of the rubber strip 3811 is located below the end of the lifting plate 322. The drive gear 372 continues to rotate, and the movable teeth reciprocate under the elastic force of the spring. When the toothed plate transmission component 374 stops moving, the toothed plate 375 stops moving, and the lifting plate 322 stops moving upward. At this time, the extrusion block 389 and the extrusion roller 321 press on the float 31, and the float 31 deforms. After the lifting plate 322 stops rising, the synchronous plate 388 contacts the synchronous block 387, and the drive rod 36 continues to rotate. The synchronous block 387 and the synchronous belt pulley assembly 386 cause the two threaded rods 385 to rotate synchronously. The rotation of the threaded rods 385 causes the limiting block 384 to slide. The limiting block 384 drives the shaft to move, while the transmission gear 383 rolls forward on the toothed plate 381. The transmission gear 383 causes the squeezing roller 321 to roll through the shaft. The rolling of the squeezing roller 321 rolls and squeezes the oil-absorbing sponge 312. The rolling of the squeezing roller 321 helps to protect the floating part 31, allowing the oil in the oil-absorbing sponge 312 to flow from one end to the other, resulting in better oil flow. A part of the rubber strip 3811 is located below the end of the lifting plate 322, preventing the oil from dripping back into the adsorption tank 12. The rubber strip 3811 facilitates the entry of the oil into the oil collection shell 33, and the oil flows into the oil outlet pipe 34 through the oil collection shell 33.

[0049] After the extrusion roller 321 completes the extrusion, the output shaft of the motor 35 rotates counterclockwise (e.g., Figure 15 As shown), the drive rod 36 rotates, which in turn causes the drive gear 372 and the timing plate 388 to rotate together. Before the timing plate 388 contacts the timing block 387, the toothed transmission component 374 and the first toothed plate 375 return to their original positions, thereby causing the lifting plate 322 and the floating component 31 to return to their original positions. The drive rod 36 continues to rotate, and the movable teeth reciprocate under the elastic force of the spring. When the timing plate 388 contacts the timing block 387, the second threaded rod 385 rotates, thereby causing the extrusion roller 321, the transmission gear 383, and the limiting block 384 to return to their original positions.
