Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device that combines micro-nano technology with ozone. Background Technology

[0002] Wastewater treatment equipment is a system that uses a combination of physical, chemical, and biological technologies to treat wastewater generated from industrial production and daily life, preventing untreated wastewater from being directly discharged and polluting natural water bodies.

[0003] With the expansion of industrial production and the acceleration of urbanization, the discharge of domestic sewage has surged. The wastewater not only contains suspended solids and conventional organic matter, but also often contains toxic, harmful and biologically recalcitrant pollutants. Traditional physical sedimentation technology is difficult to remove them effectively. Ozone oxidation technology, with its strong oxidizing properties, has been widely used in wastewater treatment.

[0004] Currently available wastewater treatment devices consist of a wastewater tank, an inlet, a regulating tank, and an outlet. When using this device, wastewater is introduced into the wastewater tank through the inlet, and chemicals are added to the tank through the regulating tank to promote sedimentation. The treated water is then exited through the inlet, completing the wastewater purification process. However, during operation, the wastewater often contains a large amount of impurities. When these impurities enter the downstream treatment unit, they can damage pumps and valves. To address this issue, existing technologies use a filter screen installed at the front of the wastewater tank to reduce impurities. However, wastewater often contains a large number of bacteria, viruses, and organic matter. To solve this problem, existing technologies use ozone tubes to aerate the water, utilizing the strong oxidizing properties of ozone to degrade bacteria, viruses, and various organic matter. However, ozone has low solubility in water, slow diffusion rate, and is easily decomposed rapidly. A large amount of ozone escapes to the surface without participating in the reaction, reducing the practicality of the device and failing to meet user needs. Summary of the Invention

[0017] This invention provides a wastewater treatment device that combines micro / nano technology with ozone. It offers the following advantages:

[0018] 1. This invention sprays ozone micro-nano bubbles into the treatment tank through a micro-nano bubble nozzle, extending the residence time of ozone in the water. A first motor drives a square column to rotate, which in turn drives a stirring blade via a transmission rod, stirring the mixing tank. This ensures that the micro-nano ozone bubbles are evenly distributed in the wastewater, allowing the wastewater to fully react with the ozone micro-nano bubbles, resulting in cleaner wastewater treatment. This improves the practicality of the device and meets the needs of users.

[0019] 2. This invention, by pulling the rotating rod, drives the spur gear upward, causing it to disengage from the tooth groove. Rotating the rotating rod raises the connecting rod, which in turn rotates the turntable, aligning the discharge hole with the bottom of the storage tank. This allows the chemical raw materials inside the storage tank to be placed into the mixing tank. The transparent outer shell and the storage tank enable precise control of the chemical raw material ratio, resulting in more accurate raw material proportions. Placing the proportioned raw materials into a sedimentation tank promotes the settling of suspended solids in the wastewater, thus improving the convenience of the device.

[0020] 3. By pressing the connecting plate, the push block moves downward, which in turn causes the support blocks on both sides to move the movable plate. The movable plate then moves the locking block, which disengages from the slot and releases the restriction on the base. This allows the baffle plate to be removed, making it easier for workers to clean the sediment accumulated at the bottom of the sedimentation tank and reducing their workload.

[0030] The technical solutions in 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This invention provides a wastewater treatment device that combines micro-nano technology with ozone, including a sedimentation tank 1, a treatment mechanism 2 on the left side of the sedimentation tank 1 for convenient disinfection of wastewater, a metering mechanism 3 on the inner side of the sedimentation tank 1 for convenient control of the amount of chemical reagents added, and a sedimentation mechanism 4 on the inner side of the sedimentation tank 1 for convenient sedimentation of suspended solids in the wastewater.

[0032] The treatment mechanism 2 includes a treatment tank 21, which is fixedly connected to the left side of the sedimentation tank 1. A connector 22 is fixedly connected to the bottom inner side of the treatment tank 21. Micro-nano bubble nozzles 23 are connected to the outer periphery of the connector 22. The micro-nano bubble nozzles 23 can spray ozone micro-nano bubbles into the treatment tank 21. A top cover 24 is fixedly connected to the top of the treatment tank 21. A hollow box 25 is fixedly connected to the top of the top cover 24. A first motor 26 is fixedly connected to the top of the hollow box 25. The output end of the first motor 26 is fixedly connected to the top of the hollow box 25. A square column 27 is fixedly connected to the top cover 24. A first motor 26 drives the square column 27 to rotate. A transmission rod 28 is slidably connected to the outside of the square column 27, causing the transmission rod 28 to rotate. The bottom of the transmission rod 28 penetrates the top cover 24. Multiple stirring paddles 210 are fixedly connected at equal intervals to the outside of the transmission rod 28, causing the stirring paddles 210 to rotate. A lifting assembly 29 is provided inside the hollow box 25. The lifting assembly 29 includes a conical tooth ring 291, which is fixedly connected to the outside of the square column 27. A transmission column 292 is rotatably connected to the right side of the inner part of the transmission column 292. A transmission bevel gear 293 is fixedly connected to the middle of the outer side of the transmission column 292. The transmission bevel gear 293 meshes with the bevel gear ring 291. When the bevel gear ring 291 rotates, the transmission bevel gear 293 will drive the transmission column 292 to rotate. A support plate 294 is fixedly connected to the left end of the transmission column 292. A plug-in column 295 is fixedly connected to the left side of the support plate 294. A connecting block 296 is fixedly connected to the top of the outer side of the transmission rod 28. The inner side of the connecting block 296 is connected to the plug-in column 295. The column 295 is slidably connected, and the plug-in column 295 will push the connecting block 296 to move, thereby driving the transmission rod 28 to move up and down reciprocally. The treatment mechanism 2 also includes a pipe 211, which is connected to the bottom of the connector 22. An ozone generator 212 is fixedly connected to the front side of the sedimentation tank 1. The bottom end of the pipe 211 passes through the treatment tank 21 and is connected to the ozone generator 212. The ozone generator 212 can deliver ozone to the connector 22 through the pipe 211. The left side of the treatment tank 21 is connected to the outlet 213.

[0033] Specifically, in wastewater treatment, the wastewater first enters sedimentation tank 1 for sedimentation to remove suspended particles. After sedimentation, the wastewater is then transported to treatment tank 21. Ozone generator 212 delivers the generated ozone gas to connector 22 via pipe 211. Connector 22 is connected to micro-nano bubble nozzle 23, allowing the ozone gas to be sprayed into treatment tank 21 in the form of micro-nano-sized bubbles. These micro-nano-sized ozone bubbles can remain in the water for a longer time, significantly extending the contact time between ozone and wastewater. Because these bubbles are very small in volume but have a relatively large specific surface area, the ozone can react more fully with the pollutants in the wastewater, improving the treatment effect. Simultaneously with the ozone bubbles being sprayed into treatment tank 21, the first motor 26 drives the square column 27 to rotate. Not only will it drive the connected transmission rod 28 to rotate, but it will also drive the bevel gear ring 291 to rotate. Since the bevel gear ring 291 meshes with the transmission bevel gear 293, the transmission bevel gear 293 further drives the support plate 294 to rotate through the transmission column 292. The support plate 294 will drive the plug-in column 295 to perform circumferential motion. During the movement, the plug-in column 295 will push the connecting block 296 to perform up-and-down reciprocating motion, so that the transmission rod 28 can also perform up-and-down reciprocating motion while rotating. This will drive the stirring paddle 210 to efficiently stir the wastewater in the treatment tank 21, ensuring that the micro-nano ozone bubbles can be evenly distributed in the wastewater, so that the ozone can fully contact and react with the pollutants in the wastewater, thereby treating the wastewater more cleanly and thoroughly, improving the practicality of the device, and meeting the needs of users. The first motor 26 will drive MS8012.

[0034] Reference Figure 2 , Figure 5 and Figure 6The quantitative mechanism 3 includes a support 31, which is fixedly connected to the top right side of the sedimentation tank 1. A transparent outer shell 32 is fixedly connected to the inner side of the support 31. Multiple storage tanks 33 are fixedly connected at equal intervals to the inner side of the transparent outer shell 32. The storage tanks 33 can be used to store chemical raw materials. A mixing tank 313 is fixedly connected to the bottom of the transparent outer shell 32. The bottom of the storage tank 33 passes through the transparent outer shell 32 and the mixing tank 313 in sequence. A turntable 34 is rotatably connected to the top of the inner side of the mixing tank 313. A discharge hole 35 is opened on the top of the turntable 34. Rotation of turntable 34 will align the discharge hole 35 with the storage bin 33. A connecting rod 37 is fixedly connected to the top of turntable 34. The top of connecting rod 37 passes through mixing bin 313 and transparent outer shell 32 and is slidably connected to a rotating rod 38. The top of rotating rod 38 passes through transparent outer shell 32. A spur gear 39 is fixedly connected to the upper outer side of rotating rod 38. A toothed groove 310 is fixedly connected to the top of transparent outer shell 32. Rotating rod 38 meshes with toothed groove 310. Spur gear 39 is limited by toothed groove 310. A mixing chamber is provided on the inner side of mixing bin 313. The mixing component 36 includes a hollow block 361, which is fixedly connected to the upper inner part of the mixing tank 313. A second motor 362 is fixedly connected to the top right side of the mixing tank 313. The output end of the second motor 362 passes through the mixing tank 313 and the hollow block 361 and is fixedly connected to a drive bevel gear 363. The second motor 362 drives the drive bevel gear 363 to rotate. A drive shaft 364 is rotatably connected to the bottom of the hollow block 361. The top end of the drive shaft 364 passes through the hollow block 361 and is fixedly connected to a drive shaft 364. The driven bevel gear 365 meshes with the driving bevel gear 363. When the driving bevel gear 363 rotates, the driven bevel gear 365 will drive the transmission shaft 364 to rotate. The upper and lower sides of the outer wall of the transmission shaft 364 are fixedly connected to the mixing paddle 366. The transmission shaft 364 will drive the mixing paddle 366 to rotate. The metering mechanism 3 also includes a feeding pipe 314. The feeding pipe 314 is connected to the bottom of the mixing tank 313. A valve 315 is provided on the outside of the feeding pipe 314. The valve 315 can control the feeding of the feeding pipe 314.

[0035] Specifically, when using this device, when wastewater flows into sedimentation tank 1, it carries a large amount of suspended particulate matter. First, pull the rotating rod 38 upward. The rotating rod 38 will drive the flat gear 39 to move upward and disengage from the tooth groove 310. Then, rotate the rotating rod 38, which will drive the connecting rod 37 to rotate, thereby further driving the turntable 34 to rotate, so that the discharge hole 35 is aligned with the storage tank 33. The chemical raw materials inside the storage tank 33 can then flow smoothly into the mixing tank 313. Through the cooperation between the transparent shell 32 and the storage tank 33, the operator can clearly observe the flow of the chemical raw materials, thereby achieving precise control of the amount of chemical raw materials added and ensuring the accuracy of the raw material ratio. After the raw materials are fed in, the second motor 362 drives the active bevel gear 363 to start rotating. Since the driven bevel gear 365 meshes with the active bevel gear 363, the driven bevel gear 365 will also rotate. Through the transmission shaft 364, it drives the mixing paddle 366 to start rotating, stirring the various chemical raw materials in the mixing tank 313 evenly. After the mixing process is completed, the valve 315 is opened, and the evenly mixed chemical substances will flow into the sedimentation tank 1, which can effectively promote the rapid sedimentation of suspended particulate matter in the wastewater, thereby achieving wastewater purification. By precisely controlling the raw material ratio and uniform mixing, the efficiency and effect of wastewater treatment are greatly improved, and the convenience of the device is enhanced. The model of the second motor 362 is MS8012.

[0036] Reference Figure 1 , Figure 7 and Figure 8 The sedimentation mechanism 4 includes a fixed plate 41, with multiple fixed plates 41 respectively fixedly connected to the front and rear sides of the sedimentation tank 1. Movable plates 42 are provided on both the left and right sides of the fixed plate 41. A locking block 43 is fixedly connected to one side of each movable plate 42, allowing the movable plate 42 to move the locking block 43. A base 44 is provided on one side of the fixed plate 41, with slots 45 on both the left and right sides of the base 44. The outer side of the locking block 43 penetrates the fixed plate 41 and engages with the slots 45, thus fixing the base 44. A baffle plate 46 is fixedly connected to one side of the base 44, slowing down the water flow and extending the water's path in the sedimentation tank 1. A fixed connection is provided in the middle of one side of the movable plate 42. There is a support block 48. A connecting plate 49 is provided on the top of the fixed plate 41. The bottom end of the connecting plate 49 passes through the fixed plate 41 and is fixedly connected to a push block 410. The bottom left and right sides of the push block 410 are in contact with the corresponding support block 48. When the connecting plate 49 drives the push block 410 to move downward, it will push the support block 48 to move. A reset assembly 47 is provided on the inner side of the fixed plate 41. The reset assembly 47 includes a guide rod 471. Multiple guide rods 471 are fixedly connected to the upper and lower sides of the corresponding fixed plate 41. The outer side of the guide rod 471 is slidably connected to the movable plate 42. Springs 472 are provided on the left and right sides of the outer wall of the guide rod 471. The springs 472 can push the movable plate 42 to move.

[0037] Specifically, multiple baffles 46 are installed in the sedimentation tank 1. The baffles 46 can effectively slow down the flow rate of water in the tank and significantly prolong the flow time of water, providing sedimentation time for suspended solids in the wastewater and ensuring that the suspended solids can settle to the bottom of the tank. When it is necessary to clean the sediment accumulated at the bottom of the sedimentation tank 1 regularly, the connecting plate 49 is pressed down. The connecting plate 49 will drive the push block 410 connected to it to move downward. The movement of the push block 410 further acts on the support block 48, causing it to move as well. The support block 48 will then drive the movable plate 42 to move. During the movement of the movable plate 42, the locking block 43 connected to it will move together, causing the locking block 43 to disengage from the locking groove 45, thereby releasing the limiting effect on the base 44. The baffles 46 can then be disassembled, making the cleaning work more efficient and convenient and reducing the workload of the staff.

[0038] Reference Figure 5 and Figure 6 The metering mechanism 3 also includes a knob 311, which is fixedly connected to the top of the rotating rod 38. The top of the storage tank 33 passes through the transparent outer shell 32 and is threadedly connected to a storage cover 312, which can close the storage tank 33.

[0039] Specifically, the knob 311 allows workers to rotate and pull the rotating rod 38, and the storage bucket 33 can be closed through the storage cover 312.

[0040] Reference Figure 1 and Figure 2 An inlet 5 is fixedly connected to the right side of the sedimentation tank 1, and a filter screen 6 is fixedly connected to the left side inside the inlet 5. The filter screen 6 can perform preliminary filtration of wastewater.

[0041] Specifically, the filter screen 6 can perform preliminary filtration of the wastewater entering the inlet 5, thereby improving the wastewater treatment efficiency.

[0042] Working principle: When treating wastewater, the wastewater first enters the sedimentation tank 1 for sedimentation. After sedimentation, the wastewater enters the treatment tank 21. The ozone generator 212 inputs ozone into the connector 22 through the pipe 211. The micro-nano bubble nozzle 23 sprays ozone micro-nano bubbles into the treatment tank 21, greatly extending the residence time of ozone in the water. Due to the small bubble volume and large specific surface area, the ozone can fully react with the wastewater. Simultaneously, the first motor 26 is activated, which drives the square column 27 to rotate. The square column 27 then drives the transmission rod 28 to rotate. When column 27 rotates, it also drives bevel ring 291 to rotate. Since transmission bevel gear 293 meshes with bevel ring 291, transmission bevel gear 293 will rotate accordingly. It will drive support plate 294 to rotate through transmission column 292. Support plate 294 will drive plug column 295 to perform circumferential motion. When plug column 295 moves, it can push connecting block 296 to perform up and down reciprocating motion. Transmission rod 28 will also perform up and down reciprocating motion while rotating, thereby driving stirring paddle 210 to stir treatment tank 21, so that micro-nano ozone bubbles can be evenly distributed in wastewater, making the wastewater cleaner.

[0043] Furthermore, when using this device, the wastewater entering the sedimentation tank 1 contains a large number of suspended particles. At this time, pulling the rotating rod 38 upward causes the rotating rod 38 to drive the spur gear 39 to move upward, causing the spur gear 39 to disengage from the tooth groove 310. Subsequently, rotating the rotating rod 38 will drive the connecting rod 37 to rotate, and the connecting rod 37 will drive the turntable 34 to rotate, thereby aligning the discharge hole 35 with the storage tank 33. This allows the chemical raw materials inside the storage tank 33 to be placed into the mixing tank 313, and the transparent outer shell 32 connects the storage tank 33 to the mixing tank 313. It can precisely control the amount of chemical raw materials added, thereby making the raw material ratio more accurate. After the addition is completed, the second motor 362 will drive the active bevel gear 363 to rotate. Since the driven bevel gear 365 meshes with the active bevel gear 363, the driven bevel gear 365 will rotate accordingly, and drive the mixing paddle 366 to rotate through the transmission shaft 364, thereby mixing the various chemical raw materials evenly. After the mixing is completed, opening the valve 315 can put the mixed chemical substances into the sedimentation tank 1, causing the suspended solids in the wastewater to settle down.

[0044] Finally, multiple baffles 46 are installed in the sedimentation tank 1. The baffles 46 can slow down the water flow and prolong the water flow time, so that the suspended solids in the wastewater can settle fully. When it is necessary to clean the sediment accumulated at the bottom of the sedimentation tank 1, the connecting plate 49 is pressed down. The connecting plate 49 will drive the pushing block 410 to move downward. The pushing block 410 will then push the support block 48 to move, which in turn will drive the movable plate 42 to move. When the movable plate 42 moves, it will drive the locking block 43 to move, so that the locking block 43 disengages from the locking groove 45, thus releasing the restriction on the base 44. At this time, the baffles 46 can be removed, so as to conveniently clean the sediment accumulated at the bottom of the sedimentation tank 1.
