Description

Technical Field

[0001] This invention relates to the field of industrial wastewater treatment technology, and in particular to a multi-stage industrial wastewater treatment device and treatment method. Background Technology

[0002] During industrial production, the discharge of industrial wastewater is enormous. The wastewater contains not only a large amount of organic pollutants and suspended impurities, but also a large amount of sludge. The sludge contains various metal wires, including iron wire, copper wire, aluminum wire and other metal impurities of different materials. These metal wires mostly come from wear and tear of production equipment, raw material residues and parts falling off.

[0003] In existing technologies, multi-stage industrial wastewater treatment devices mainly focus on the degradation of organic pollutants and the removal of suspended particles in wastewater. The treatment of sludge mostly adopts only simple sedimentation and separation methods, lacking targeted metal wire retrieval. As a result, the metal wires in the sludge cannot be effectively separated. On the one hand, the metal wires are easily discharged with the sludge, which can easily cause secondary pollution, and the metal resources cannot be recycled, resulting in resource waste. On the other hand, the existing treatment technologies have poor adaptability to different types of metal wires in the sludge, making it difficult to achieve comprehensive and efficient retrieval.

[0004] Therefore, it is necessary to provide a multi-stage industrial wastewater treatment device and method to solve the above-mentioned technical problems. Summary of the Invention

[0015] To address the above problems, the present invention also provides a multi-stage treatment method for industrial wastewater, comprising the following steps: T1: Industrial wastewater is first discharged into the integrated treatment tower.

[0016] Compared with related technologies, the multi-stage industrial wastewater treatment device and method provided by the present invention have the following beneficial effects: This invention provides a multi-stage industrial wastewater treatment device. Through the coordinated operation of a retrieval component, a collection component, and various internal parts, the sludge discharged from the integrated treatment tower is centrally discharged into a settling cylinder for pre-treatment, achieving efficient separation and recovery of metal wires from the sludge. The retrieval component, through the relative rotation of the first and second stirring cylinders, combined with the dual action of the main bionic hook plate and electromagnetic chuck, can accurately hook and adsorb metal wires from the sludge. Simultaneously, through the linkage of the lifting limit plate and the lifting guide rod, it achieves both upward unloading and downward retrieval, continuously retrieving metal wires from the sludge and improving the comprehensiveness of the retrieval. The collection component uses opposing secondary bionic hook plates to peel the metal wires off the main bionic hook plate, and with the help of a bidirectional screw-driven debris collection box, the metal wires are then separated from the water through a separation box. The water flows back to the collection tank for recycling. The overall structure has a high retrieval and recovery rate, effectively avoiding resource waste. This invention provides a multi-stage industrial wastewater treatment device. Through the cooperation of a squeezing assembly, two sets of rinsing assemblies, and various internal components, it achieves deep sludge dewatering and water resource recycling. The squeezing assembly uses a variable-diameter pipe with an auger for conveying, and a cam-driven variable-diameter pipe adjusts the angle and uses a ring filter to improve sludge dewatering efficiency and reduce sludge moisture content. The separated wastewater is returned to a collection tank for reuse via a second water pump, saving water resources. The rinsing assembly uses a first water pump to draw water from the collection tank, and then uses a main spray pipe and opposing auxiliary spray pipes to thoroughly rinse the bionic hook plate, preventing metal wire residue from affecting subsequent retrieval. This invention provides a method for multi-stage treatment of industrial wastewater. This method uses the aforementioned multi-stage industrial wastewater treatment device to effectively improve the separation and recovery of metal wires in sludge, thus avoiding resource waste.

Two lifting limit plates 11 are rotatably mounted on one end of their respective ends at the top of the first mixing drum 20. The other ends of both lifting limit plates 11 extend through to the top of the cleaning chamber 10 and are fixedly mounted with the same limiting ring plate.

Two short shafts are rotatably installed at the bottom of the cleaning chamber 10. A fourth gear 31 and a fifth gear 35 are fixedly installed on the outer walls of the two short shafts, respectively. The fourth gear 31 meshes with the first rack 12, and the fifth gear 35 meshes with the second rack 34. A first pulley is fixedly installed on the outer wall of each of the two short shafts. The same first belt 32 is sleeved on the outer side of the two first pulleys. The second motor 14 is fixedly installed on the top of the cleaning chamber 10. The output shaft of the second motor 14 is fixedly connected to one of the short shafts. When the second motor 14 is started, its output shaft drives one of the short shafts to rotate. The short shaft drives the other short shaft to rotate synchronously through the transmission of the first pulley and the first belt 32. The two short shafts respectively mesh with the first rack 12 through the fourth gear 31 and the second rack 34 through the fifth gear 35, driving the lifting limit plate 11 to lower the first mixing drum 20. At the same time, the lifting guide rod 33 drives the second mixing drum 23 to rise, realizing one upward unloading and one downward retrieval, continuously retrieval of metal wires in the sludge.

[0022] The collection assembly includes two fixed plates 36, two debris collection boxes 9, two water collection tanks 8, and a third motor 21. Both fixed plates 36 are fixedly installed on the top inner wall of the cleaning chamber 10, and auxiliary bionic hook plates 37 are fixedly installed on both the outer and inner walls of the two fixed plates 36. The auxiliary bionic hook plates 37 and the main bionic hook plate 22 form a counter-scraping structure, with a large scraping contact area and uniform force, which can completely peel off the metal wires attached to the main bionic hook plate 22, avoiding metal wire residue from affecting subsequent retrieval. A bidirectional lead screw 16 is rotatably installed on one side of the outer wall of the connecting seat 27, and the third motor 21 is fixed. Installed on top of the stationary cylinder 6, the third motor 21 is connected to the bidirectional lead screw 16 for transmission. Two chip collection boxes 9 are respectively installed through and slidably on both sides of the connecting seat 27. The width of the two chip collection boxes 9 is less than the distance between the two lifting limit plates 11, which facilitates the movement of the two chip collection boxes 9 relative to each other. The ends of the two chip collection boxes 9 that are close to each other extend into the connecting seat 27 and are each fixedly installed with two abutments. Both chip collection boxes 9 are threadedly connected to the bidirectional lead screw 16. Two water collection tanks 8 are fixedly installed on the top of the bracket 1. Two discharge pipes 7 are fixedly installed on one end of the outer wall of the stationary cylinder 6. The other end of the discharge pipe 7 is fixedly connected to two water collection tanks 8. A valve is installed on the discharge pipe 7. After the sewage and sludge have settled and separated, opening the valve allows water to be discharged into the water collection tanks 8. One end of a sewage discharge pipe 24 is also fixedly installed at the bottom of the settling cylinder 6. A separation box 15 is fixedly installed on the top of each of the two water collection tanks 8. The separation box 15 is connected to a chip collection box 9.

The other ends of the two chip discharge pipes 17 are fixedly connected to the two separation boxes 15 respectively. Each of the two separation boxes 15 has a sliding outlet on its opposite side. Each separation box 15 is equipped with a sieve box 18. The bottom of the sieve box 18 has an opening, and a first filter screen is fixedly installed in the opening. A second filter screen is fixedly installed in the separation box 15. When the third motor 21 is started, the output shaft of the third motor 21 drives the bidirectional lead screw 16 to rotate. The bidirectional lead screw 16 drives the two chip collection boxes 9 to slide relative to each other along the guide rod. The metal wire falls into the chip collection box 9. The metal wire in the chip collection box 9 and the water enter the separation box 15 through the chip discharge pipe 17. The second filter screen in the separation box 15 and the first filter screen in the sieve box 18 filter the water. The water flows to the water collection tank 8, and the metal wire remains in the sieve box 18.

[0023] The bionic hooks on the multiple auxiliary bionic hook plates 37 are all arranged opposite to the bionic hooks on the multiple main bionic hook plates 22. By aligning them, when the main bionic hook plate 22 on the outer wall of the second mixing drum 23 comes into contact with the auxiliary bionic hook plate 37 on the inner fixing plate 36 of the cleaning chamber 10, the auxiliary bionic hook plate 37 can scrape the surface of the main bionic hook plate 22, causing the metal wire to fall off the main bionic hook plate 22.

[0024] Both chip collection boxes 9 have an inclined surface at the top. Through the inclined surface, the metal wire quickly slides down to the tail of the box, avoiding accumulation at the top. A guide rod is fixedly installed on one side of the outer wall of the connecting seat 27, and both chip collection boxes 9 are slidably connected to the guide rod.

[0025] In this embodiment: Industrial wastewater first enters the integrated treatment tower 2. After multi-stage treatment in the integrated treatment tower 2, the resulting sludge is transported to the settling cylinder 6 through the first sludge discharge pipe 3, the second sludge discharge pipe 4, and the third sludge discharge pipe 5. Inorganic flocculant is first added to the settling cylinder 6, followed by organic coagulant aid, so that the sludge can quickly complete the initial sedimentation in the settling cylinder 6 and become flocculent. After a period of settling, the sludge and water are separated. The valve on the discharge pipe 7 is opened, and the water is discharged from the discharge pipe 7 into the water collection tank 8. At this time, the second stirring cylinder 23 is located in the sludge. The fourth motor 25 is started. The output shaft of the fourth motor 25 drives the second stirring cylinder 23 to rotate in the sludge. At the same time, the electromagnetic chuck 29 on the outer wall of the second stirring cylinder 23 is energized to generate magnetic force. During the rotation, the main bionic hook plate 22 hooks the non-adsorbable metal wires in the sludge, and the electromagnetic chuck 29 adsorbs the fine metal wires, thus initially retrieval the metal wires. After the second mixing drum 23 has been fishing for a certain period of time, the second motor 14 is started. Its output shaft drives one of the short shafts to rotate. The short shaft drives the other short shaft to rotate synchronously through the transmission of the first pulley and the first belt 32. The two short shafts respectively mesh with the first rack 12 through the fourth gear 31 and the second rack 34 through the fifth gear 35, driving the lifting limit plate 11 to lower the first mixing drum 20. At the same time, the lifting guide rod 33 drives the second mixing drum 23 to rise, realizing one rising unloading and one falling fishing. When the first stirring drum 20 descends into the settling drum 6, the first gear 19 on the outer wall of the first stirring drum 20 contacts and meshes with the second gear 26, activating the first motor 13. Its output shaft drives the rotating shaft to rotate, and the rotating shaft, through the meshing of the third gear 28 with the first gear 19, drives the first stirring drum 20 to rotate within the sludge. Simultaneously, the electromagnetic chuck 29 on the inner wall of the first stirring drum 20 is energized to generate magnetic force, which, in conjunction with the main bionic hook plate 22, hooks and adsorbs the metal wires within the sludge again. When the second stirring drum 23 rises into the cleaning chamber 10, the main bionic hook plate 22 on the outer wall of the second stirring drum 23 contacts the auxiliary bionic hook plate 37 on the fixing plate 36 inside the cleaning chamber 10, and the second stirring drum 23 continues to rotate. The auxiliary bionic hook plate 37 scrapes the surface of the main bionic hook plate 22, and at the same time, the power supply of the electromagnetic chuck 29 on the corresponding main bionic hook plate 22 is turned off. After the magnetic force disappears, the metal wire falls off the main bionic hook plate 22, and the third motor 21 is started. The output shaft of the third motor 21 drives the bidirectional lead screw 16 to rotate. The bidirectional lead screw 16 drives the two chip collection boxes 9 to slide relative to each other along the guide rod. The metal wire falls into the chip collection box 9. The metal wire in the chip collection box 9 and the water enter the separation box 15 through the chip discharge pipe 17. The second filter screen in the separation box 15 and the first filter screen in the sieve box 18 filter the water. The water flows to the water collection box 8, and the metal wire remains in the sieve box 18. When it is necessary to collect the metal wire, the sieve box 18 can be pulled out through the sliding outlet of the separation box 15 to remove the metal wire.

A seventh motor 45 is fixedly installed on one side of the outer wall of the base 40. The output shaft of the seventh motor 45 is fixedly connected to one end of the second rotating shaft. The auger 46 is rotatably installed inside the reducing pipe 41. A fifth motor 45 is fixedly installed at one end of the reducing pipe 41. 3. The fifth motor 43 is fixedly connected to one end of the auger 46. The reducer 41 has two annular openings, and annular filter screens 48 are fixed inside each of the two annular openings. Two annular water collecting plates 47 are fixedly installed on the outer wall of the reducer 41. One end of the first pumping pipe is fixedly installed on the outer wall of each of the two annular water collecting plates 47. Two second water pumps 42 are fixedly installed on one side of the outer wall of the water collection tank 8. The other ends of the two first pumping pipes are fixedly connected to the inlet ends of the two second water pumps 42, respectively. One end of the first drain pipe is fixedly installed on the outlet end of each of the two second water pumps 42. The other ends of the two first drain pipes extend to the water collection tank. Inside the box 8, the output shaft of the fifth motor 43 drives the auger 46 to rotate inside the reducing pipe 41. The auger 46 pushes the sludge along the reducing pipe 41 toward the narrow end. During the movement, the sludge is squeezed, achieving sludge-water separation. The water generated by the sludge squeezing penetrates the annular filter screen 48 inside the annular opening and flows into the outer annular water collection plate 47 for collection. Then, two second water pumps 42 are started. The second water pumps 42 draw water from the annular water collection plate 47 through the first water pumping pipe and then transport it to the water collection box 8 for temporary storage through the first drain pipe, realizing water recovery and reuse. The dewatered sludge is discharged through the narrow end of the reducing pipe 41, completing the sludge dewatering.

[0029] Each set of rinsing components includes a first water pump 39, a main spray pipe 30, and two auxiliary spray pipes 49. The first water pump 39 is fixedly installed on the outer wall of the cleaning chamber 10. One end of a second water suction pipe is fixedly installed at the water inlet of the first water pump 39, and the other end of the second water suction pipe extends into the water collection tank 8. The main spray pipe 30 is fixedly installed inside the cleaning chamber 10. One end of a second drain pipe is fixedly installed at the water outlet of the first water pump 39, and the other end of the second drain pipe extends into the cleaning chamber 10 and is fixedly connected to the main spray pipe 30. The two auxiliary spray pipes 49 are both fixedly installed on the outer wall of the main spray pipe 30. The auxiliary spray pipes 49 assist the main spray pipe 30 in expanding the rinsing range and targeting specific areas. The cleaning process thoroughly removes residual impurities from hard-to-reach areas such as the gaps in the main bionic hook plate 22 and the gaps in the secondary bionic hook plate 37, preventing the adhesion of fine metal wires and sludge. After the main bionic hook plate 22 has completed the removal of metal wires, the first water pump 39 is activated. The first water pump 39 draws water temporarily stored in the water collection tank 8 through the second water pipe and delivers it to the main spray pipe 30 in the cleaning chamber 10 through the second drain pipe. The main spray pipe 30 then distributes the water to two opposing secondary spray pipes 49. The main spray pipe 30 sprays water downwards onto the main bionic hook plate 22 and the secondary bionic hook plate 37, while the two secondary spray pipes 49 simultaneously spray water onto the gaps in the hook plates to wash away any remaining metal wires on the hook plates and accelerate the removal of the metal wires.

[0030] Both auxiliary spray pipes 49 are set in opposite directions, and the opposing sprays form a counter-current water flow with stronger impact force, which can quickly remove stubborn sludge and metal wire debris attached to the hook plate, and the rinsing effect is better than that of unidirectional spraying.

[0031] In this embodiment: Open the valve on the drain pipe 24. The sludge that has been dredged by the metal wire in the settling cylinder 6 is transported to the reducer pipe 41 through the bottom drain pipe 24. At this time, the fifth motor 43 is started. The output shaft of the fifth motor 43 drives the auger 46 to rotate in the reducer pipe 41. The auger 46 pushes the sludge along the reducer pipe 41 to the narrow end. During the movement, the sludge is squeezed to achieve mud-water separation. The water generated by the sludge squeezing penetrates the annular filter screen 48 in the annular opening and flows into the outer annular water collection plate 47 for collection. Then, the two second water pumps 42 are started. The second water pumps 42 draw water from the annular water collection plate 47 through the first water pumping pipe and then transport it to the water collection tank 8 through the first drain pipe for temporary storage, so as to realize water recovery and reuse. The dewatered sludge is discharged through the narrow end of the reducer pipe 41, thus completing the sludge dewatering. After the main bionic hook plate 22 completes the stripping of the metal wire, the first water pump 39 is started. The first water pump 39 draws water temporarily stored in the water collection tank 8 through the second water pumping pipe and delivers it to the main spray pipe 30 in the cleaning chamber 10 through the second drain pipe. The main spray pipe 30 then diverts the water to two opposing auxiliary spray pipes 49. The main spray pipe 30 sprays water downwards onto the main bionic hook plate 22 and the auxiliary bionic hook plate 37. The two auxiliary spray pipes 49 spray water simultaneously onto the gaps of the hook plate to wash away the metal wires that have not yet detached from the hook plate, accelerate the detachment of the metal wires, and prevent the metal wires from falling back into the settling cylinder 6 along with the main bionic hook plate 22. When it is necessary to adjust the angle of the reducing tube 41 to speed up the dehydration effect, the sixth motor 44 is started. The output shaft of the sixth motor 44 drives the fixed shaft of the reducing tube 41 to rotate, adjusting the tilt angle of the reducing tube 41. At the same time, the seventh motor 45 is started. The output shaft of the seventh motor 45 drives the second rotating shaft to rotate, so that the cam 38 supports the bottom of the reducing tube 41 to assist in adjusting the angle and improve the dehydration efficiency.

[0032] Third embodiment: This embodiment provides a multi-stage treatment method for industrial wastewater, including the following steps: T1: Industrial wastewater is first discharged into the integrated treatment tower 2. After multi-stage core treatment such as flocculation, sedimentation and filtration, the pollutants in the wastewater are converted into sludge, which is then transported to the settling tank 6 through the first sludge discharge pipe 3, the second sludge discharge pipe 4, and the third sludge discharge pipe 5. T2: First add inorganic flocculant into the settling cylinder 6, then add organic coagulant aid, so that it can complete the settling and sedimentation in the settling cylinder 6, and achieve the initial separation of sludge and a small amount of supernatant. T3: The metal wires are retrieved from the sludge in the settling cylinder 6 by the retrieval component and collected by the collection component. T4: Completes the separation and treatment of metal impurities in wastewater. The wastewater initially separated in the settling tank 6 can be discharged in compliance with standards or further treated.
