Description

Technical Field

[0001] This invention relates to the field of aquaculture wastewater treatment, specifically a device for purifying and treating aquaculture wastewater from a chicken farm. Background Technology

[0002] Chicken farms are agricultural facilities specializing in the large-scale breeding of chickens. They typically employ modern management models, which may include enclosed chicken houses, automated feeding systems, and temperature control equipment to improve production efficiency and animal welfare. During regular cleaning of the chicken houses, water is used to flush away feces, feed residue, feathers, etc., forming high-concentration organic wastewater. The wastewater ferments and produces harmful gases such as ammonia and hydrogen sulfide, which breed mosquitoes, flies, and pathogens, threatening the health of nearby residents. Therefore, it is necessary to treat the wastewater in a timely manner.

[0003] Chemical treatment of aquaculture wastewater mainly involves adding chemical agents, such as microbial agents, chemical flocculants, and decolorizing agents, to remove pollutants such as suspended solids, organic matter, nitrogen, phosphorus, and heavy metals from the wastewater through chemical reactions. However, the treatment process generates a large amount of sludge, which needs to be filtered through a screen to remove the sludge and impurities. As the amount of sludge and impurities increases, the surface of the screen is easily blocked. Existing treatment devices use a threaded rod to drive a moving block, and the cleaning brush on the moving block cleans the surface of the screen. Although this can scrape the sludge and impurities off the screen, it can only concentrate the sludge and impurities in the sludge discharge pipe on one side of the screen. As the amount of sludge and impurities in the sludge discharge pipe increases, the cleaning brush moving back will carry some sludge and impurities and cover the screen, making it difficult to achieve continuous cleaning of the screen and thus difficult to ensure continuous wastewater treatment.

This allows the drain pipe to first inject wastewater into the treatment box, followed by the injection of microbial agents, thus achieving continuous wastewater treatment. The treated wastewater is then discharged, and the filter screen is rinsed, thereby achieving continuous treatment and preventing filter screen blockage from affecting the normal treatment of wastewater.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8 The diagram shows a wastewater purification device for a chicken farm, comprising a base 1 and a circular shell 2 fixedly installed on top of the base 1. Multiple treatment boxes 3, arranged symmetrically on the inner side of the circular shell 2, are used to inject wastewater to be treated. A drug injection valve 4 and a feeding pipe 5 are fixedly installed on the top of the circular shell 2, with the drug injection valve 4 located to the right of the feeding pipe 5, allowing the feeding pipe 5 to inject wastewater into the treatment boxes 3 directly below. The drug injection valve 4 injects microbial agents into the treatment boxes 3 to treat the wastewater. A filter screen 6 is installed inside the treatment box 3 to filter out sludge and impurities from the wastewater. The device also includes a switching mechanism for continuous feeding and drug injection of wastewater, installed inside the circular shell 2.

[0022] The switching mechanism includes an annular frame 7 rotatably mounted inside the circular shell 2. The annular frame 7 can rotate the positions of multiple processing boxes 3. The switching mechanism also includes two symmetrically fixed gear rings 10 fixedly mounted inside the annular frame 7. A drive motor 11 is fixedly mounted on the outer side of the circular shell 2. A rotating rod 12 is fixedly mounted on the output end of the drive motor 11. The rotating rod 12 is rotatably mounted inside the circular shell 2, and two first gears 13, which respectively cooperate with the two gear rings 10, are fixedly mounted on the outer side of the rotating rod 12. The processing boxes 3 are fixedly mounted inside the annular frame 7, so that the drive motor 11 drives the first gears 13 to rotate through the rotating rod 12. The first gears 13 drive the gear rings 10 to rotate, so that the gear rings 10 drive the annular frame 7 to rotate synchronously, thereby realizing the rotation of multiple processing boxes 3. The treatment box 3 is rotated so that it can move sequentially below the feed pipe 5 and the injection valve 4. The feed pipe 5 first injects wastewater into the treatment box 3, and then the injection valve 4 injects microbial agents into the treatment box 3 to achieve continuous wastewater treatment. A drain box 14 is fixedly installed on the inner side of the circular shell 2. The top of the drain box 14 has an arc-shaped structure, and the bottom of the treatment box 3 is in contact with the top of the drain box 14, allowing the treatment box 3 to move along the top of the drain box 14. Drainage holes are provided on both the top and bottom of the drain box 14, and the drain hole on the top of the drain box 14 is located to the right of the injection valve 4. When the drain hole of the treatment box 3 is aligned with the drain hole of the drain box 14, the treated wastewater in the treatment box 3 can enter the drain box through the drain hole. Within the 14th section, continuous wastewater treatment is achieved. An installation box 15 is fixedly installed inside the circular shell 2. The bottom of the installation box 15 has an arc-shaped structure, allowing the treatment box 3 to move along the bottom of the installation box 15 when in contact with it. A drain nozzle 16 is fixedly installed inside the installation box 15, and a drain pipe 17 is fixedly installed between the drain nozzle 16 and the outer side of the circular shell 2. The drain pipe 17 can connect to a drain pipe. Water is injected into the drain nozzle 16, aligning the drain hole of the treatment box 3 with the drain nozzle 16. The drain nozzle 16 then sprays water into the treatment box 3 to clean the filter screen 6, facilitating the removal of sludge and impurities, achieving a cleaning and anti-clogging effect, and ensuring the continuous wastewater treatment by the filter screen 6. Two symmetrically distributed positioning rings 33 are fixedly installed on the outer side of the ring frame 7. The outer side of the positioning rings 33 contacts the inner side of the circular shell 2, providing support for the rotation of the ring frame 7 and improving the stability of the rotation. A storage box 34 is fixedly installed at the bottom of the circular shell 2, and the storage box 34 is located directly below the drain nozzle 16, so that the drain nozzle 16 can flush the sludge and impurities cleaned from the treatment box 3 into the storage box 34 for centralized treatment. A guide plate 35 is fixedly installed on the inner side of the drain box 14, and a connecting pipe 36 extending to the outer side of the circular shell 2 is fixedly installed on the outer side of the drain box 14. The wastewater pipe after purification is connected to the connecting pipe 36, so that the wastewater entering the drain box 14 can be discharged from the connecting pipe 36 through the guide plate 35.A rubber sealing sleeve 39 is fixedly installed between the outer side of the drain nozzle 16 and the inner side of the mounting box 15. The rubber sealing sleeve 39 provides a seal at the connection between the drain nozzle 16 and the mounting box 15, preventing leakage.

[0023] Example 2: Please refer to Figures 3-8 This embodiment further illustrates Example 1. The shaking mechanism shown in the figure includes two symmetrically fixed sliding plates 8 fixedly mounted on the outside of the filter screen 6. The two sliding plates 8 can repeatedly bend and straighten the filter screen 6. The shaking mechanism also includes two symmetrically rotatably mounted mounting rods 18 on the inside of the processing box 3. An eccentric wheel 19 is fixedly mounted on the outside of the mounting rods 18. A sliding groove is provided on the inside of the processing box 3 for the sliding plates 8 to be limited and slid. A plurality of first tension springs 20 and two mounting blocks 40 are fixedly mounted between the side of the sliding plate 8 away from the filter screen 6 and the inside of the processing box 3. A U-shaped plate 21 is fixedly installed on the top of the 40, and a push plate 41 is fixedly installed on the top of the U-shaped plate 21. Utilizing the elasticity of the first tension spring 20, the push plate 41 abuts against the outside of the eccentric wheel 19. When the mounting rod 18 rotates, the eccentric wheel 19, in conjunction with the first tension spring 20, intermittently pushes the push plate 41 to reciprocate. The U-shaped plate 21, in turn, drives the sliding plate 8 to move synchronously, causing the two sliding plates 8 to repeatedly bend and straighten the filter screen 6, shaking off the sludge and impurities on the surface of the filter screen 6, thus improving cleaning efficiency. A transmission rod 22 is provided between the two mounting rods 18. The outer edges of the mounting rod 18 and the transmission rod 22... Each side is fixedly equipped with a transmission wheel 23, and a synchronous toothed belt 24 is rotatably mounted between the three transmission wheels 23. When the transmission rod 22 rotates, the transmission wheels 23, in conjunction with the synchronous toothed belt 24, can drive the two mounting rods 18 to rotate synchronously. The outer side of the ring frame 7 has a groove for mounting the synchronous toothed belt 24, and the transmission rod 22 is rotatably mounted inside the groove. A second gear 25 is fixedly mounted on the end of the transmission rod 22 away from the transmission wheel 23. An arc-shaped rack 26 is fixedly mounted on the inner side of the circular shell 2, so that when the ring frame 7 rotates, it can drive the second gear 25 on the transmission rod 22 and the arc-shaped rack. When the two gears 26 come into contact, the arc-shaped rack 26 can drive the second gear 25 to rotate. Two symmetrically distributed baffles 37 are fixedly installed on the outer side of the push plate 41, and the outer side of the baffles 37 is in contact with the outer side of the eccentric wheel 19, so that the eccentric wheel 19 can push the push plate 41 to move between the two baffles 37, ensuring that the eccentric wheel 19 can smoothly push the push plate 41 to move. An inner support frame 38 is fixedly installed on the inner side of the groove of the ring frame 7. The inner support frame 38 is in contact with the inner and outer sides of the synchronous toothed belt 24, providing support for the inner side of the synchronous toothed belt 24 and improving the smoothness of the rotation and movement of the synchronous toothed belt 24.

[0024] Example 3: Please refer to Figures 3-7This embodiment further illustrates other embodiments. The feeding mechanism shown in the figure includes a sealing plate 9 fixedly installed inside the treatment box 3. The sealing plate 9 can provide a seal for the bottom of the filter screen 6. The feeding mechanism also includes a movable plate 27 slidably installed inside the treatment box 3. The bottom of the movable plate 27 is in contact with the top of the sealing plate 9. Water permeable holes are provided on the surfaces of both the movable plate 27 and the sealing plate 9. When the water permeable holes on the movable plate 27 are aligned with the water permeable holes on the sealing plate 9, the wastewater filtered by the filter screen 6 can be discharged from the water permeable holes. When the water permeable holes on the movable plate 27 are misaligned with the water permeable holes on the sealing plate 9, the sealing plate 9 can be sealed, so that the microbial agent can fully react or degrade with the wastewater and harmful substances remaining in the sludge impurities, thereby achieving full treatment of the sludge impurities. A push rod 28 that slides through the treatment box 3 and the annular frame 7 is fixedly installed on one side of the movable plate 27. A stop block 29 is fixedly installed at the end of the push rod 28 away from the movable plate 27. The abutment 29 has a hemispherical structure. A guide ring 30 is fixedly installed on the inner side of the circular shell 2, and the abutment 29 is in contact with the inner side of the guide ring 30. When the ring frame 7 rotates, it can drive the abutment 29 on the push rod 28 to move along the inner side of the guide ring 30. A stop bar 31 is fixedly installed on the inner side of the ring frame 7. When the abutment 29 is in contact with the stop bar 31, the reaction force of the stop bar 31 on the abutment 29 causes the abutment 29 to push the moving plate 27 to move through the push rod 28. The water-permeable holes on the movable plate 27 are aligned with the water-permeable holes on the sealing plate 9. A pull rod 42 is fixedly installed on the side of the movable plate 27 away from the push rod 28. One end of the pull rod 42 slides through the treatment box 3 and the ring frame 7. A second tension spring 32 is fixedly installed between the pull rod 42 and the ring frame 7. When the movable plate 27 moves, the second tension spring 32 can be compressed by the pull rod 42. When the stop block 29 moves away from the stop strip 31, the rebound force of the second tension spring 32 can be used to reset the stop block 29.

[0025] Working principle: First, the operator connects the wastewater conveying pipe to the feeding pipe 5, and the microbial agent conveying pipe to the injection valve 4. Then, the clean water conveying pipe is connected to the drain pipe 17, allowing the feeding pipe 5 to inject wastewater into the treatment box 3 directly below. Subsequently, the drive motor 11 runs, driving the first gear 13 to rotate via the rotating rod 12. The first gear 13 drives the gear ring 10 to rotate, causing the two gear rings 10 to drive the ring frame 7 to rotate along the inner side of the circular shell 2. The treatment box 3 containing wastewater moves below the injection valve 4, and the next treatment box 3 moves below the feeding pipe 5. The microbial agent is then injected into the wastewater-containing treatment box 3 through the injection valve 4, while the feeding pipe 5 injects wastewater into the empty treatment box 3. This allows for continuous and sequential feeding of wastewater and microbial agents. Because the permeable holes on the moving plate 27 and the sealing plate 9 are staggered, the sealing plate 9 and the moving plate 27 provide a seal to the bottom of the filter screen 6, enabling the microbial agents to fully react with or degrade harmful substances remaining in the wastewater and sludge. As the drive motor 11 operates, the treatment box 3 containing the treated wastewater moves above the drain hole on the outside of the drain box 14, aligning the drain hole on the treatment box 3 with the drain hole on the drain box 14. Simultaneously, the abutment 29 aligned with the treatment box 3 contacts the baffle 31 inside the guide ring 30. The reaction force of the baffle 31 on the abutment 29 causes the abutment 29 to push the moving plate 27 via the push rod 28. The moving plate 27 aligns with the water-permeable holes on the sealing plate 9, allowing the treated wastewater to pass through the filter screen 6 into the water-permeable holes of the moving plate 27 and sealing plate 9, and then into the drainage box 14 through the drainage hole of the treatment box 3. Thus, with the intermittent operation of the drive motor 11, continuous feeding, chemical injection, and discharge of wastewater are achieved. When the drainage hole on the treatment box 3 aligns with the drainage nozzle 16, the clean water supply pipe injects clean water into the drainage nozzle 16 through the drainage connector 17, causing the drainage nozzle 16 to rinse the filter screen 6 and the inside of the treatment box 3. Simultaneously, the second gear 25 corresponding to the treatment box 3 contacts the arc-shaped rack 26, causing the arc-shaped rack 26 to drive the transmission rod 22 to rotate via the second gear 25. 22 drives the two mounting rods 18 to rotate synchronously through the cooperation of the transmission wheel 23 and the synchronous toothed belt 24. The mounting rods 18 drive the eccentric wheel 19 to rotate, causing the eccentric wheel 19 to push the push plate 41 to move. The push plate 41 pushes the slide plate 8 along the inner side of the treatment box 3 through the U-shaped plate 21 and the mounting block 40, and stretches the second tension spring 32, causing the two slide plates 8 to bend the filter screen 6. Thus, with the rotation of the eccentric wheel 19 and the rebound force of the second tension spring 32, the slide plate 8 repeatedly bends and straightens the filter screen 6, shaking off the sludge and impurities remaining on the surface of the filter screen 6. The sludge and impurities on the filter screen 6 can then quickly fall into the storage box 34, realizing the rapid cleaning of the filter screen 6, ensuring the continuous treatment of wastewater by the treatment box 3, thereby improving the wastewater treatment efficiency.
