Description

Technical Field

[0001] The invention belongs to the technical field of battery acid treatment, in particular to a battery acid wastewater treatment device. Background Art

[0002] Battery acid is produced during the crushing, disassembling and recycling process of used batteries. Battery acid contains a large amount of harmful substances, which may cause serious pollution to the atmosphere, water bodies and soil. Therefore, it is listed as hazardous waste. In order to develop in the direction of environmental protection and intelligence, useless battery acid needs to undergo a series of treatments such as impurity removal and filtration before it can be discharged or recycled.

[0003] A patent with publication number CN219489805U discloses a filtering device for treating battery acid wastewater. The device rotates through the cooperation of guide blades, conical seats and rotating shafts, changes the direction of water flow, reduces part of the water pressure, and allows the wastewater that continues to flow downward to overflow along the surface of the buffer springboard. Under the action of the annular guide plate, an energy dissipation jump angle is formed, which further dissipates the pressure of the wastewater injection, thereby protecting the top medium layer of the filter mechanism, preventing the medium from running away, and improving the filtering efficiency.

[0004] In the above-mentioned prior art, when treating battery wastewater, a coagulant is generally added to the battery wastewater, which can make the heavy metals and impurities in the battery wastewater form flocs, realize solid-liquid separation, and then take out the flocs. After the prior art adds a coagulant to the battery wastewater to form flocs, it is necessary to wait for the flocs to settle, and then collect the precipitates in a centralized manner. It is necessary to regularly collect and clean the precipitated flocs in the reaction tank. When cleaning and collecting the flocs, it is necessary to stop adding the battery wastewater to the reaction tank, because the flocs need to settle to the bottom of the reaction tank before they can be collected in a centralized manner. If the battery wastewater is continuously added to the sedimentation tank for treatment, the battery wastewater originally in the reaction tank will be shaken, thereby causing the originally precipitated flocs to float up, and the flocs cannot be collected in a centralized manner.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] Embodiment 1: Figure 1-Figure 4 As shown, a battery acid wastewater treatment device according to an embodiment of the present invention comprises a first cylinder 1, a plurality of first pipes 11 are fixedly connected to one side of the first cylinder 1, a first arc-shaped pipe 111 is fixedly connected to one end of the plurality of first pipes 11 away from the first cylinder 1, a plurality of second pipes 12 are fixedly connected to the other side of the first cylinder 1, a second arc-shaped pipe 121 is fixedly connected to one end of the second pipes 12 away from the first cylinder 1, a first ring 2 is rotatably connected inside the first cylinder 1, first cylindrical bars 22 are fixedly connected to both sides of the first ring 2, and the first cylindrical bars 22 A second ring 221 is fixedly connected to the upper ends, and the second ring 221 can rotate at the upper end inside the first cylinder 1. A third ring 24 is provided on the upper end of the first ring 2. The first cylindrical bar 22 slides through both sides of the third ring 24. Cylindrical electromagnets 25 are fixedly connected to the lower ends of both sides of the third ring 24. First circular holes 21 are respectively opened on both sides of the first ring 2. Arc grooves 211 are respectively opened on both sides of the first circular hole 21. Arc clamping blocks 212 are slidably connected in the arc grooves 211. The cylindrical electromagnet 25 is located in the middle of the first circular hole 21.

[0030] Specifically, when treating used batteries, since the battery wastewater contains a lot of heavy metals, direct discharge will cause pollution to the environment. The wastewater in the battery needs to be treated before discharge. When treating the battery wastewater, adding a coagulant to the battery wastewater can make the suspended matter and some heavy metal ions in the battery wastewater form flocs, and then achieve solid-liquid separation through precipitation, and then take out the precipitated flocs to treat the battery wastewater. In the prior art, after adding the coagulant to the battery wastewater, it is necessary to wait for the reaction time to allow the flocs to settle to the bottom, and then collect the precipitates in a centralized manner. It is necessary to regularly collect and clean the precipitated flocs in the reaction tank. When cleaning and collecting the flocs, it is necessary to stop adding the battery wastewater to the reaction tank, and the battery wastewater cannot be continuously treated;

[0031] When using the present invention, the battery waste water is discharged into the first arc tube 111 through the external water pipe, and then flows into the first cylinder 1 through the first pipe 11, and then the coagulant is mixed with the magnetic powder, and discharged into the second arc tube 121 through the external water pipe, and then discharged into the first cylinder 1 through the second pipe 12 to mix with the battery waste water. At the same time, the magnetic powder and coagulant are added to the battery waste water, which can effectively absorb bacteria, viruses, oil and various tiny particles in the battery waste water. Under the action of the magnetic field, the flocs formed can be efficiently and quickly precipitated, thereby To achieve the decontamination effect, the first ring 2 is then driven to rotate, and the first ring 2 drives the third ring 24 to rotate through the first cylindrical bar 22, and the third ring 24 drives the cylindrical electromagnets 25 on both sides to rotate in the battery wastewater, thereby accelerating the reaction time of the coagulant, the magnetic powder and the battery wastewater. After a period of reaction, the cylindrical electromagnet 25 is energized to make it have adsorption capacity, and the third ring 24 is continuously driven to drive the cylindrical electromagnet 25 to rotate. Since the flocs formed contain magnetic powder, they can be adsorbed on the outside of the cylindrical electromagnet 25. When too much floccules are adsorbed on the outer side of the first ring 2, the third ring 24 is driven to drive the cylindrical electromagnet 25 to move upward, so that the cylindrical electromagnet 25 is completely located at the upper end of the first ring 2, and then the two arc-shaped clamping blocks 212 are driven to slide toward the middle in the arc-shaped groove 211 at the same time, so that the arc-shaped clamping blocks 212 can be closely attached to the outer side of the cylindrical electromagnet 25, and then the third ring 24 is driven to drive the cylindrical electromagnet 25 to slide downward. Since the arc-shaped clamping blocks 212 can be closely attached to the outer side of the cylindrical electromagnet 25, the cylindrical electromagnet 25 slides downward in the middle of the two arc-shaped clamping blocks 212. At the same time, the flocs adsorbed on the outside are scraped off at the upper end of the arc-shaped clamping block 212, and then the clean cylindrical electromagnet 25 is re-extended into the battery waste water for stirring and adsorption. While scraping off the flocs on the outside of the cylindrical electromagnet 25, battery waste water, coagulant and magnetic powder can be continuously added to the first cylinder 1 for reaction, which solves the problem that when cleaning the flocs formed by waste battery waste water, coagulant and magnetic powder, battery waste water cannot be continuously added to react with coagulant and magnetic powder, and the reaction needs to be stopped regularly to clean up the reacted flocs.

[0032] like Figure 4As shown, one side of the arc-shaped clamping block 212 of the present embodiment is fixedly connected to one side of the inside of the arc-shaped groove 211 through a spring 213, and the upper end of the arc-shaped clamping block 212 is fixedly connected to the second cylindrical bar 23, and the third ring 24 is provided with a waist-shaped hole 241 corresponding to the position of the second cylindrical bar 23, and the second cylindrical bar 23 can slide inside the waist-shaped hole 241, and the upper end of the second cylindrical bar 23 is slidably connected to the second ring 221, and the middle part of the second cylindrical bar 23 is respectively provided with a second fixed block 244 through damping sliding, and the two second fixed blocks 244 are connected by a connecting rod group, and the connecting rod group includes connecting rods 243 that are rotatably connected to one side of the second fixed block 244, and the two connecting rods 243 are rotatably connected to the first fixed block 242 at one end away from the second fixed block 244, and the first fixed block 242 is fixed to the upper end of the third ring 24.

[0033] Specifically, when the third ring 24 is driven to drive the cylindrical electromagnet 25 to move upward, the third ring 24 drives the connecting rod 243 to rotate to both sides through the first fixed block 242, and the rotation of the connecting rod 243 on both sides drives the second fixed block 244 to move to both sides at the same time. Since a damper is installed between the second fixed block 244 and the second cylindrical bar 23, the friction between the second fixed block 244 and the second cylindrical bar 23 increases, which can drive the second cylindrical bar 23 to move to both sides in the waist-shaped hole 241 at the same time. The second cylindrical bar 23 drives the arc clamping block 212 to slide to both sides in the arc groove 211 and squeeze the spring 213, so that the arc clamping block 212 is away from both sides of the cylindrical electromagnet 25 to avoid rubbing against the outer side of the cylindrical electromagnet 25. When the third ring 24 drives the cylindrical electromagnet 25 to move downward, the third ring 24 drives the connecting rod 243 to rotate toward the middle at the same time through the first fixed block 242, and the connecting rod 243 drives the second cylindrical bar 23 to rotate in the same direction to the middle through the second fixed block 244, and the second cylindrical bar 23 drives the arc clamping block 212 to slide toward the middle at the same time, so that the arc clamping block 212 can be close to the outside of the cylindrical electromagnet 25, and then the third ring 24 is driven to drive the cylindrical electromagnet 25 to slide downward. Since the arc clamping block 212 can be close to the outside of the cylindrical electromagnet 25, the cylindrical electromagnet 25 slides downward in the middle of the two arc clamping blocks 212, and the flocs adsorbed on the outside are scraped off at the upper end of the arc clamping block 212.

[0034] like Figure 4 As shown, the two connecting rods 243 included in the connecting rod assembly of this embodiment are inclined toward the middle of the lower end, and the two connecting rods 243 are V-shaped.

[0035] Specifically, since the two connecting rods 243 are V-shaped, when the two connecting rods 243 are driven to move upward, the angle formed by the upper ends of the two connecting rods 243 can be increased, and when the two connecting rods 243 are driven to move downward, the angle formed by the upper ends of the two connecting rods 243 can be reduced.

[0036] like Figure 5 As shown, in this embodiment, the upper edge of the first circular hole 21 is respectively fixedly connected to the second cylinder 26, and one side of the second cylinder 26 is respectively fixedly connected to the third pipe 261, and the ends of the third pipe 261 are respectively fixedly connected to the telescopic pipe 262, and the upper ends of the two telescopic pipes 262 are commonly fixedly connected to the first cylindrical block 263, the first cylindrical block 263 can rotate on the upper end of the first cylinder 1, and the upper end of the first cylindrical block 263 is rotatably connected to the fourth pipe 264.

[0037] Specifically, by driving the third ring 24 to drive the cylindrical electromagnet 25 to slide downward, the flocs adsorbed on the outside are scraped off at the upper end of the arc-shaped clamping block 212 and enter the second cylinder 26 to prevent the flocs from falling. Subsequently, by connecting the air pump to the upper end of the fourth pipe 264 through an external pipe, the air pump is started, and the flocs collected in the second cylinder 26 are sucked out and collected centrally through the telescopic pipe 262 and the third pipe 261.

[0038] like Figure 3 As shown, in this embodiment, a fourth ring 3 is fixedly connected to the inside of the lower end of the first cylinder 1, and a plurality of through holes are provided on the edge of the fourth ring 3. A fifth ring 31 is provided at the lower end of the fourth ring 3, and the fifth ring 31 can slide in the first cylinder 1. A plurality of second cylindrical blocks 311 are fixedly connected to the positions of the upper ends of the fifth ring 31 corresponding to the through holes, and the second cylindrical blocks 311 can slide into the through holes.

[0039] Specifically, when the coagulant, magnetic powder and battery waste water are added into the first cylinder 1 for reaction, the fifth ring 31 is always close to the fourth ring 3, and the second cylindrical block 311 is always inserted in the through hole to prevent the battery waste water from flowing out. When the reaction is completed, the cylindrical electromagnet 25 absorbs the reacted flocs and drives the fifth ring 31 to drive the second cylindrical block 311 to slide downward, so that the second cylindrical block 311 slides out of the through hole, so that the battery waste water after impurities are removed flows out, and then the fifth ring 31 is driven again to drive the second cylindrical block 311 to be inserted into the through hole, so that the next round of battery waste water treatment can be carried out.

[0040] like Figure 3 As shown, in this embodiment, a first stirring assembly is provided in the middle of the fourth ring 3 , and the first stirring assembly includes a conical block 32 rotatably connected to the middle of the fourth ring 3 , and a plurality of corrugated plates 321 are fixed to the outer edge of the conical block 32 .

[0041] Specifically, after the coagulant, magnetic powder and battery waste water are added into the first cylinder 1, the conical block 32 is then driven to rotate, and the conical block 32 drives a plurality of wave plates 321 to rotate simultaneously, stirring the coagulant, magnetic powder and battery waste water, and cooperating with the stirring of the cylindrical electromagnet 25, the speed of the fusion reaction is accelerated.

[0042] like Figure 3 As shown, the edge of the conical block 32 of this embodiment is in a downwardly inclined shape, and the upper end of the conical block 32 is fixedly connected to the first cylindrical block 263 through the first cylindrical rod 33.

[0043] Specifically, since the edge of the conical block 32 is inclined downward, the flocs slide down the bevel to the upper end of the fourth ring 3, and the cylindrical electromagnet 25 rotates along the upper end of the fourth ring 3, which can better absorb the flocs. When the first ring 2 rotates, it can drive the second cylinder 26 to rotate. The second cylinder 26 can drive the first cylindrical block 263 to rotate through the third pipe 261 and the telescopic pipe 262. The first cylindrical block 263 can drive the conical block 32 to rotate through the first cylindrical rod 33 to stir the battery waste water.

[0044] like Figure 6 As shown, in this embodiment, the lower edge of the first cylinder 1 is fixedly connected to an L-shaped ring 373 through a rectangular strip 13, the middle of the lower end of the L-shaped ring 373 is fixedly connected to a third cylinder 38, and the upper end of the third cylinder 38 is fixedly connected to an annular filter plate 36.

[0045] Specifically, after the battery wastewater reacts with the coagulant and the magnetic powder, the cylindrical electromagnet 25 adsorbs the formed flocs. The battery wastewater may still contain fine impurities, and the fifth ring 31 drives the second cylindrical block 311 to slide downward, so that the second cylindrical block 311 slides out of the through hole, so that the battery wastewater after impurities are removed flows to the upper end of the annular filter plate 36 for further filtration.

[0046] like Figure 6 As shown, in this embodiment, the lower end of the first cylinder 1 is rotatably connected to the sixth ring 37, and the two sides of the lower end of the sixth ring 37 are rotatably connected to the third cylindrical rod 371 respectively. The lower end of the third cylindrical rod 371 is fixed with a scraper 372, and the scraper 372 can slide along the upper end of the annular filter plate 36.

[0047] Specifically, after a long period of filtration, too many impurities will accumulate on the upper end of the annular filter plate 36. Then, the third cylindrical rod 371 is driven to drive the scraper 372 to rotate, and the impurities on the upper end of the annular filter plate 36 are transferred into the L-shaped ring 373 for collection. Then, the sixth ring 37 is driven to drive the scraper 372 to completely scrape off the upper end of the annular filter plate 36.

[0048] Embodiment 2: Figure 6As shown, comparative example 1, wherein another implementation of the present invention is: a second stirring assembly is provided in the middle of the annular filter plate 36, the second stirring assembly is consistent with the first stirring assembly in structure, the two conical blocks 32 are fixedly connected by a second cylindrical rod 34, a feeding assembly is provided between the second stirring assembly and the first stirring assembly, the feeding assembly comprises a fifth pipe 35 fixedly connected to the edge of the first cylinder 1, the fifth pipe 35 is fixedly connected to an annular pipe 351 at one end away from the first cylinder 1, and a drain outlet 39 is fixedly connected to one side of the lower end of the third cylinder 38.

[0049] Specifically, the battery waste water is acidic and needs to be neutralized before it can be discharged. The filtered battery waste water falls into the third cylinder 38, and then is discharged into the alkaline solution into the annular pipe 351 through the external water pipe, and then flows into the third cylinder 38 through the fifth pipe 35 to neutralize the battery waste water. The first stirring component at the upper end drives the second stirring component to rotate, stirs the alkaline solution and the battery waste water, accelerates the reaction speed, and then is discharged from the drain port 39.

[0050] Working principle: when in use, the battery waste water is discharged into the first arc tube 111 through the external water pipe, and then flows into the first cylinder 1 through the first pipe 11, and then the coagulant is mixed with the magnetic powder, and discharged into the second arc tube 121 through the external water pipe, and then discharged into the first cylinder 1 through the second pipe 12 to mix with the battery waste water, and then the first ring 2 is driven to rotate, and the first ring 2 drives the third ring 24 to rotate through the first cylindrical bar 22, and the third ring 24 drives the cylindrical electromagnets 25 on both sides to rotate in the battery waste water. When the first ring 2 rotates, it can drive the second cylinder 26 to rotate, and the second cylinder 26 can drive the first cylindrical block 263 to rotate through the third pipe 261 and the telescopic pipe 262, and the first cylindrical block 263 can drive the conical block 32 to rotate through the first cylindrical rod 33, and the conical block 32 drives a plurality of wave plates 321 to rotate at the same time, stir the coagulant, magnetic powder and battery waste water, and cooperate with the stirring of the cylindrical electromagnet 25 to accelerate the speed of the fusion reaction;

[0051] After a period of reaction, the cylindrical electromagnet 25 is energized to make it have adsorption capacity, and the third ring 24 is continuously driven to drive the cylindrical electromagnet 25 to rotate. Since the flocs formed contain magnetic powder, they can be adsorbed on the outside of the cylindrical electromagnet 25. When too much flocs are adsorbed on the outside of the cylindrical electromagnet 25, the third ring 24 is driven to drive the cylindrical electromagnet 25 to move upward. The third ring 24 drives the connecting rod 243 to rotate to both sides through the first fixed block 242. The rotation of the connecting rod 243 on both sides simultaneously drives the second fixed block 244 to move to both sides. Since a damper is installed between the second fixed block 244 and the second cylindrical bar 23, the friction between the second fixed block 244 and the second cylindrical bar 23 increases, which can drive the second cylindrical bar 23 to move to both sides in the waist-shaped hole 241 at the same time. The second cylindrical bar 23 drives the arc clamping block 212 to move to both sides in the arc groove 211. The spring 213 is slid and squeezed to make the arc-shaped clamping block 212 away from the two sides of the cylindrical electromagnet 25 to avoid rubbing against the floccules adsorbed on the outside of the cylindrical electromagnet 25. When the third ring 24 drives the cylindrical electromagnet 25 to move downward, the third ring 24 drives the connecting rod 243 to rotate toward the middle at the same time through the first fixed block 242, and the connecting rod 243 drives the second cylindrical bar 23 to rotate in the same direction to the middle through the second fixed block 244. The second cylindrical bar 23 drives the arc-shaped clamping block 212 to slide toward the middle at the same time, so that the arc-shaped clamping block 212 can be close to the outside of the cylindrical electromagnet 25. Then, the third ring 24 is driven to drive the cylindrical electromagnet 25 to slide downward. Since the arc-shaped clamping block 212 can be close to the outside of the cylindrical electromagnet 25, the cylindrical electromagnet 25 slides downward in the middle of the two arc-shaped clamping blocks 212, and the floccules adsorbed on the outside are scraped off at the upper end of the arc-shaped clamping block 212.

[0052] Then, the cylindrical electromagnet 25 is driven downward by driving the third ring 24, and the flocs adsorbed on the outside are scraped off at the upper end of the arc-shaped clamping block 212 and enter the second cylinder 26 to prevent the flocs from falling. Then, the air pump is connected to the upper end of the fourth pipe 264 through an external pipe, and the air pump is started to suck out the flocs collected in the second cylinder 26 through the telescopic pipe 262 and the third pipe 261 for centralized collection;

[0053] When the reaction is completed, the cylindrical electromagnet 25 absorbs the reacted flocs, and then drives the fifth ring 31 to drive the second cylindrical block 311 to slide downward, so that the second cylindrical block 311 slides out of the through hole, so that the battery waste water after impurity removal flows to the upper end of the ring filter plate 36 for further filtration. After a long period of filtration, too many impurities will accumulate on the upper end of the ring filter plate 36. Then, the third cylindrical rod 371 is driven to drive the scraper 372 to rotate, and the impurities on the upper end of the ring filter plate 36 are transferred into the L-shaped ring 373 for collection. Then, the sixth ring 37 is driven to drive the scraper 372 to completely scrape off the upper end of the ring filter plate 36.

[0054] Battery waste water is acidic and needs to be neutralized before it can be discharged. The filtered battery waste water falls into the third cylinder 38, and then is discharged into the annular pipe 351 through the external water pipe into the alkaline solution, and then flows into the third cylinder 38 through the fifth pipe 35 to neutralize the battery waste water. The first stirring component at the upper end drives the second stirring component to rotate, stirs the alkaline solution and the battery waste water, accelerates the reaction speed, and then is discharged from the drain port 39.
