DETAILED DESCRIPTION

[0029] 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.

[0030] Embodiment 1

[0031] like Figure 1-Figure 5 As shown, an automatic sewage pool cleaning device described in an embodiment of the present invention includes an automatic sewage cleaning pool 1, a first water pool 2 is fixedly connected to one side of the automatic sewage cleaning pool 1 through a first connecting pipe 11, a second connecting pipe 21 is fixedly connected to the first water pool 2 away from the automatic sewage cleaning pool 1, a magnetizing device is provided in the middle of the second connecting pipe 21, the magnetizing device includes a first cylinder 22 that rotates and penetrates the upper end of the second connecting pipe 21, a plurality of first rectangular holes 221 are provided around the first cylinder 22, a separation device is provided inside the first water pool 2, the separation device includes a first V-shaped plate 25 and a second V-shaped plate 26 that are respectively fixed inside the first water pool 2, the first V-shaped plate 25 and the second V-shaped plate 26 are arranged in parallel, second rectangular holes 251 are respectively provided on both sides of the first V-shaped plate 25, a third rectangular hole 261 is provided in the middle of the second V-shaped plate 26, and magnet plates 262 are respectively fixed on both sides of the second V-shaped plate 26 close to the first V-shaped plate 25.

[0032] Specifically, the pharmaceutical industry generates wastewater when producing drugs. The pharmaceutical industry usually has very strict requirements for wastewater treatment, which must comply with environmental regulations and standards. Existing technologies generally use biological treatment methods for the generated pharmaceutical wastewater, using microorganisms to decompose and transform organic matter, thereby decomposing organic matter into inorganic matter. Biological methods are divided into aerobic biological treatment and anaerobic biological treatment. Aerobic biological treatment uses oxygen as an oxidant to oxidize and decompose organic matter in the wastewater. Anaerobic biological treatment places the wastewater in an oxygen-free environment and uses anaerobic microorganisms to decompose organic matter. After the pharmaceutical wastewater is discharged into 1, it is treated using a biological treatment method. Pharmaceutical wastewater usually contains complex organic matter. , inorganic matter, heavy metal ions, etc., pharmaceutical wastewater directly enters the sewage automatic cleaning tank 1 for treatment, which will cause the accumulation of pollutants that are difficult to remove inside the sewage automatic cleaning tank 1, thereby affecting the performance and life of the equipment. The sewage automatic cleaning tank 1 needs to be regularly maintained and serviced to ensure its long-term stable operation. In particular, for the high requirements for pharmaceutical wastewater treatment, more frequent equipment inspections and repairs, as well as higher-level maintenance and service, may be required. When using this device, the sewage automatic cleaning tank 1 is first discharged into the first water tank 2 through the second connecting pipe 21. After the pharmaceutical wastewater enters the first water tank 2, the chemical substances containing magnetic substances will be dissolved, and then discharged into the second connecting pipe 22 through the first cylinder. The inside of the tube 21 is fused with pharmaceutical wastewater, and the dissolving liquid can be a metal salt, such as FeCl3 or NiCl2. Then, the dissolved magnetic chemical substances are fused with the pharmaceutical wastewater, and the magnetic substances are gradually deposited on the surface of the activated carbon and the impurities, and chemical bonds are formed on the surface, so that the impurities in the pharmaceutical wastewater and the activated carbon have magnetic properties. By rotating the first cylinder 22, the dissolved magnetic chemical substances inside are discharged into the second connecting tube 21 through the first rectangular hole 221 to merge with the pharmaceutical wastewater, and then the pharmaceutical wastewater enters the first water pool 2, and the pharmaceutical wastewater flows along the oblique side of the first V-shaped plate 25 from the second rectangular hole 251 to the side of the second V-shaped plate 26. The magnet plate 262 is provided on one side of the second V-shaped plate 26. The magnetized impurities and activated carbon in the pharmaceutical wastewater are adsorbed, and then flow out from the third rectangular hole 261, and then discharged into the automatic sewage cleaning tank 1 along the first connecting pipe 11 for biological treatment. Before the pharmaceutical wastewater is discharged into the automatic sewage cleaning tank 1 for biodegradation, the impurities and activated carbon contained in the pharmaceutical wastewater are magnetized, and then the magnet plate 262 adsorbs the magnetized impurities and activated carbon in the pharmaceutical wastewater, which solves the impact of impurities and activated carbon in the pharmaceutical wastewater on the automatic sewage cleaning tank 1, improves the wastewater treatment efficiency and quality, reduces the operating cost and maintenance difficulty of the automatic sewage cleaning tank 1, enhances the adaptability and stability of the system, and promotes environmental protection and sustainable development.

[0033] like Figure 4As shown, the magnetization device also includes first arc blocks 23 fixedly connected to the positions corresponding to the first rectangular holes 221 around the first cylinder 22. The first arc blocks 23 are hollow in structure. The first arc blocks 23 are connected to the inside of the first cylinder 22. A plurality of circular holes 231 are provided on the edge of the first arc blocks 23.

[0034] Specifically, when the impurities and activated carbon in the pharmaceutical wastewater are magnetized, the dissolved magnetic chemicals are discharged into the first cylinder 22, and then when the first cylinder 22 is rotated, the magnetic chemicals dissolved inside are thrown out from the first rectangular hole 221, enter the first arc block 23, and then thrown out from the circular hole 231 to merge with the pharmaceutical wastewater. The first arc block 23 can stir the wastewater and the dissolved magnetic chemicals to make the fusion more uniform.

[0035] like Figure 4 As shown, the upper end of the first cylinder 22 is rotatably connected to a ring 222, the upper end of the ring 222 is fixedly connected to a second cylinder 223, both sides of the ring 222 are fixedly connected to the second connecting tube 21 through L-shaped blocks 2221, the middle of the ring 222 is fixedly connected to a cylindrical rod 24 through a rectangular block 244, the cylindrical rod 24 is located in the middle of the first cylinder 22, and rectangular bars 241 are fixedly connected to the positions corresponding to the first rectangular hole 221 around the cylindrical rod 24, and a second arc block 243 is fixedly connected to one side of the rectangular bar 241 through a first spring 242, and the second arc block 243 can slide in the first rectangular hole 221.

[0036] Specifically, after the dissolved magnetic chemicals are discharged into the first cylinder 22, the first cylinder 22 is driven to rotate. At this time, the upper end of the first cylinder 22 and the ring 222 rotate, and then the first rectangular hole 221 slides along the hypotenuse of the second arc block 243. The second arc block 243 slides toward the side close to the cylindrical rod 24 and squeezes the first spring 242 until the second arc block 243 completely slides out of the first rectangular hole 221. At this time, the dissolved magnetic chemicals in the first cylinder 22 can be thrown out from the first rectangular hole 221 to the first arc block 23 and discharged from the circular hole 231 to merge with the pharmaceutical wastewater. When the first cylinder 22 stops rotating, the second arc block 243 slides to one side of the first rectangular hole 221, and the first spring 242 releases its elastic force to push the second arc block 243 into the first rectangular hole 221. When the first cylinder 22 stops rotating, the dissolved magnetic chemicals can be prevented from flowing out of the first rectangular hole 221, and the pharmaceutical wastewater can be prevented from entering the first cylinder 22.

[0037] like Figure 3 As shown, a gear ring 224 is fixedly connected to the outer side of the upper end of the first cylinder 22, and a gear 225 is meshed with the gear ring 224. The gear 225 can rotate on the upper end of the second connecting tube 21. The output end of the motor 226 is fixedly connected to the upper end of the gear 225, and the motor 226 is fixedly connected to the second connecting tube 21 through a motor seat.

[0038] Specifically, the starter motor 226 drives the gear ring 224 to rotate through the gear 225, and the gear ring 224 drives the first cylinder 22 to rotate. The centripetal force generated by the rotation of the first cylinder 22 can throw out the dissolved magnetic chemical substances inside.

[0039] like Figure 6 As shown, a plurality of first baffles 256 are provided on a side of the first V-shaped plate 25 close to the second V-shaped plate 26 .

[0040] Specifically, when the pharmaceutical wastewater mixed with dissolved magnetic chemicals flows into the first water pool 2, it then flows along the second rectangular hole 251 to between the first V-shaped plate 25 and the second V-shaped plate 26. When the pharmaceutical wastewater passes through the first baffles 256 provided on one side of the first V-shaped plate 25, the first baffles 256 can increase a certain resistance to the pharmaceutical wastewater, reduce the flow rate of the pharmaceutical wastewater, and make the pharmaceutical wastewater flow slowly between the first V-shaped plate 25 and the second V-shaped plate 26, thereby increasing the contact time between the pharmaceutical wastewater and the magnet plate 262. The magnet plate 262 has a better adsorption effect on impurities and activated carbon in the pharmaceutical wastewater.

[0041] like Figure 6 As shown, protrusions 252 are respectively provided on both sides of the upper end of the first V-shaped plate 25, and a V-shaped block 253 is fixedly connected to the upper ends of the protrusions 252. Second scrapers 27 are respectively slidably provided on both sides of the lower end of the V-shaped block 253, and the second scrapers 27 can slide along one side of the magnet plate 262 respectively.

[0042] Specifically, when a large amount of impurities and activated carbon are adsorbed on the surface of the magnet plate 262, the adsorption effect of the magnet plate 262 will deteriorate, and the impurities and activated carbon on the surface of the magnet plate 262 need to be cleaned. The second scraper 27 is driven to slide on the surface of the magnet plate 262 to scrape off the impurities and activated carbon on the surface of the magnet plate 262. The magnet plate 262 can continue to adsorb while ensuring the adsorption effect.

[0043] like Figure 5-Figure 6 As shown, the first V-shaped plate 25 is provided with a slide groove 2521 on one side close to the protrusion 252, and a slider is slidably connected inside the slide groove 2521, and a first scraper 255 is rotatably connected to one side of the slider, and the upper end of the second scraper 27 is fixed with a first cylindrical block 271, and the first cylindrical block 271 can slide inside the second cylindrical block 273. The first cylindrical block 271 is fixed to the inside of the second cylindrical block 273 through the second spring 272, and slide rails 254 are fixed on both sides of the lower end of the V-shaped block 253, and the second cylindrical block 273 can slide inside the slide rails 254, and the first collecting box 28 is fixed on both sides of the first water pool 2.

[0044] Specifically, when the second scraper 27 scrapes the impurities and activated carbon on the surface of the magnet plate 262 to the side of the first scraper 255, the lower end of the second scraper 27 is provided with a bevel, which can slide to the upper end along the side of the first scraper 255, and the second scraper 27 drives the first cylindrical block 271 to slide to the inside of the second cylindrical block 273, while squeezing the second spring 272. After the second scraper 27 scrapes the impurities and activated carbon to the upper end of the first scraper 255, it then drives the first scraper 255 to slide upward, and the first scraper 255 pushes the impurities and activated carbon to the upper end of the protrusion 252, and then drives the first scraper 255 to rotate to discharge the impurities into the first collecting box 28 for collection.

[0045] like Figure 7 As shown, a filtering device is provided at one end of the second connecting pipe 21 away from the first water pool 2, and the filtering device includes a rectangular frame 3 provided at one end of the second connecting pipe 21, a filter plate 31 is installed inside the upper end of the rectangular frame 3, and the upper end of the filter plate 31 is slidably connected to the third scraper 32, and a fourth rectangular hole 33 is opened on one side of the upper end of the rectangular frame 3, and the fourth rectangular hole 33 is located at the upper end of the filter plate 31, and a second collecting box 36 is fixedly connected to a position corresponding to the fourth rectangular hole 33 on one side of the rectangular frame 3.

[0046] Specifically, before the impurities and activated carbon in the pharmaceutical wastewater are magnetized, the larger impurities can be filtered and the pharmaceutical wastewater can be discharged into the rectangular frame 3. The pharmaceutical wastewater is filtered through the filter plate 31, and the impurities are left on the upper end of the filter plate 31. Then, the third scraper 32 is driven to slide on the upper end of the filter plate 31 to push the impurities into the fourth rectangular hole 33 and discharge them into the second collection box 36 for collection to prevent the filter plate 31 from being blocked and to enable continuous filtration.

[0047] Embodiment 2

[0048] As shown in 1 , compared with Example 1, another embodiment of the present invention is: a sedimentation box 4 is fixedly connected to the lower end of the rectangular frame 3, one side of the lower end of the sedimentation box 4 is fixedly connected to the second connecting pipe 21, and an electric valve 211 is provided on the side of the second connecting pipe 21 close to the sedimentation box 4.

[0049] Specifically, the pharmaceutical wastewater filtered by the filter plate 31 flows into the sedimentation tank 4 for sedimentation, and gravity is used to accelerate the sedimentation of the remaining impurities and activated carbon particles. A mud discharge valve is set at the bottom to discharge the sediment regularly. During sedimentation, the electric valve 211 is in a closed state. After the sedimentation is completed, the electric valve 211 is opened to allow the water inside the sedimentation tank 4 to flow into the first water pool 2 through the second connecting pipe 21 for further purification.

[0050] like Figure 7As shown, a buffer assembly is provided at the lower end of the rectangular frame 3, and the buffer assembly includes two first wave plates 35 obliquely arranged inside the rectangular frame 3, the two first wave plates 35 are cross-arranged with a gap between them, and a plurality of second wave plates 351 are respectively fixed to the upper ends of the first wave plates 35, and the second wave plates 351 are perpendicularly arranged to the first wave plates 35.

[0051] Specifically, when the pharmaceutical wastewater flows from the rectangular frame 3 to the sedimentation box 4, it needs to slide along the first wave plate 35, and at the same time needs to pass through a plurality of second wave plates 351 provided on the upper end of the first wave plate 35, so as to slow down the flow speed of the pharmaceutical wastewater, so that the pharmaceutical wastewater can stop faster after entering the sedimentation box 4, thereby speeding up the sedimentation time.

[0052] Working principle: the pharmaceutical wastewater is discharged into the rectangular frame 3, and the pharmaceutical wastewater is filtered by the filter plate 31, leaving the impurities on the upper end of the filter plate 31, and then the third scraper 32 is driven to slide on the upper end of the filter plate 31, pushing the impurities into the fourth rectangular hole 33, and discharged into the second collection box 36 for collection; then it slides along the first wave plate 35, and at the same time needs to pass through a plurality of second wave plates 351 provided on the upper end of the first wave plate 35, so that the flow speed of the pharmaceutical wastewater is slowed down, and then it enters the sedimentation box 4, so that the pharmaceutical wastewater can be stationary faster after entering the sedimentation box 4, and the sedimentation time is accelerated;

[0053] The precipitated pharmaceutical wastewater enters the second connecting pipe 21, and then the dissolved magnetic chemical substances are discharged into the first cylinder 22. The starting motor 226 drives the gear ring 224 to rotate through the gear 225, and the gear ring 224 drives the first cylinder 22 to rotate. At this time, the upper end of the first cylinder 22 and the ring 222 rotate, and then the first rectangular hole 221 slides along the hypotenuse of the second arc block 243, and the second arc block 243 slides to the side close to the cylindrical rod 24 and squeezes the first spring 242 until the second arc block 243 completely slides out of the first rectangular hole 221. At this time, the dissolved magnetic chemical substance in the first cylinder 22 can be thrown out from the first rectangular hole 221 to the first arc block 23, discharged from the circular hole 231 and merged with the pharmaceutical wastewater. When the first cylinder 22 stops rotating, the second arc block 243 slides to one side of the first rectangular hole 221, and the first spring 242 releases its elastic force to push the second arc block 243 into the first rectangular hole 221. When the first cylinder 22 stops rotating, the dissolved magnetic chemical substance can be prevented from flowing out of the first rectangular hole 221, and the pharmaceutical wastewater can be prevented from entering the first cylinder 22.

[0054] When the pharmaceutical wastewater mixed with the dissolved magnetic chemical substances flows into the first water pool 2, it then flows along the second rectangular hole 251 to between the first V-shaped plate 25 and the second V-shaped plate 26. When the pharmaceutical wastewater passes through the first baffles 256 provided on one side of the first V-shaped plate 25, the first baffles 256 can increase a certain resistance to the pharmaceutical wastewater, reduce the flow rate of the pharmaceutical wastewater, and make the pharmaceutical wastewater flow slowly between the first V-shaped plate 25 and the second V-shaped plate 26, thereby increasing the contact time between the pharmaceutical wastewater and the magnet plate 262. When the surface of the magnet plate 262 absorbs more impurities and activated carbon, the second scraper 27 is driven to slide on the surface of the magnet plate 262 to scrape off the impurities and activated carbon on the surface of the magnet plate 262. When the impurities and activated carbon on the surface of the magnet plate 262 are scraped to the side of the first scraper 255, the lower end of the second scraper 27 is provided with a bevel, which can slide to the upper end along the side of the first scraper 255, and the second scraper 27 drives the first cylindrical block 271 to slide to the inside of the second cylindrical block 273, and squeezes the second spring 272 at the same time. After the second scraper 27 scrapes the impurities and activated carbon to the upper end of the first scraper 255, it then drives the first scraper 255 to slide upward, and the first scraper 255 pushes the impurities and activated carbon to the upper end of the protrusion 252, and then drives the first scraper 255 to rotate to discharge the impurities into the first collection box 28 for collection, and then the pharmaceutical wastewater enters the sewage automatic cleaning pool 1 to be treated by biological treatment.
