Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment, and in particular to an upflow integrated sewage treatment equipment. Background Technology

[0002] The term "upflow" in integrated wastewater treatment equipment refers to the upward flow of wastewater within the equipment. Wastewater enters from the bottom and, during its ascent, comes into full contact with various treatment media and microorganisms within the equipment, undergoing physical, chemical, or biological reactions. This process removes and purifies pollutants from the wastewater. Integrated wastewater treatment equipment combines multiple stages or processes within the wastewater treatment process into a compact device or system, enabling comprehensive wastewater treatment to meet prescribed discharge standards or reuse requirements.

[0003] In the coagulation and sedimentation stage of wastewater treatment, coagulants and other chemicals need to be added to the wastewater. Stirring and mixing ensures the chemicals and wastewater come into full contact, forming flocs for subsequent sedimentation and separation. However, existing single-stirring equipment often results in uneven mixing of chemicals and wastewater, with some areas having excessively high concentrations while others have insufficient concentrations. This leads to incomplete disinfection, inadequate coagulation, incomplete floc formation, poor sedimentation, potentially increased suspended solids in the effluent, and turbidity, increasing wastewater treatment costs and energy consumption. Flotation, on the other hand, allows suspended solids and other impurities in the water to adhere to air bubbles and float to the surface, forming scum. During wastewater sedimentation, air flotation allows suspended solids and sediments to adhere to air bubbles and float to the surface, forming scum. Without an air flotation and scum scraping mechanism, scum will continuously accumulate on the water surface, affecting not only the appearance of the equipment and the on-site environment, but also potentially causing some scum to sink back into the water, resulting in secondary pollution, reducing the operating efficiency of the equipment, increasing the maintenance costs of the equipment, and in severe cases, potentially leading to equipment failure.

The second spur gear on the second connecting rod meshes with the inside of the rack and pinion ring on the right side. When the second rotating rod rotates, the meshing transmission between the gear and the rack and pinion ring drives the rack and pinion ring to perform circular motion within the top box. The fixing ring on the outer side of the rack and pinion ring moves along with it, and the connecting block connected to the inner wall of the fixing ring drives the second support plate to move, causing the scraper on the bottom wall of the second support plate to move as well. The scraper scrapes away the scum on the water surface along the direction of the guide plate, collecting the scum to prevent its accumulation from affecting the treatment effect and equipment operation. This effectively improves the efficiency and timeliness of scum removal, keeps the water surface clean, improves the environmental conditions at the wastewater treatment site, extends the service life of the equipment, and reduces maintenance costs.

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] like Figure 1 - Figure 4 As shown: An upflow integrated sewage treatment device includes a box 1, and a multi-layer stirring and mixing mechanism 2 is provided on the left side of the inside of the box 1;

[0034] The multi-layer mixing mechanism 2 includes: a first motor 201, two device boxes 205 and four second bevel gears 207. The bottom wall of the first motor 201 is fixedly connected to the top left side of the box 1. The output end of the first motor 201 passes through the top of the box 1 and is fixedly connected to a first rotating rod 202. By fixing the first motor 201 to the top of the box 1, the bottom of the first motor 201 is supported. The output end of the first motor 201 passes through the top of the box 1 and is connected to the first rotating rod 202, thereby driving the first rotating rod 202 to rotate inside the box 1.

[0035] A first connecting ring 203 is fixedly connected to the outer side of the middle part of the first rotating rod 202. A stirring rod 204 is fixedly connected to the outer side of each first connecting ring 203. The first connecting ring 203 on the outer side of the first rotating rod 202 is connected to the stirring rod 204. As the first rotating rod 202 is driven, the outer first connecting ring 203 and the stirring rod 204 will also rotate synchronously. The rotating stirring rod 204 will stir and mix the sewage and medicine inside the tank 1, so that the sewage and medicine are fully mixed.

[0036] Both device boxes 205 are located on the outer sides of the upper and lower ends of the first rotating rod 202. A first bevel gear 206 is fixedly connected to the outer sides of both ends of the first rotating rod 202. Two first bevel gears 206 are located inside the two device boxes 205. Four second bevel gears 207 are located on the front and rear sides of the inner sides of the two device boxes 205. The bottom of each second bevel gear 207 meshes with the bottom of the other two bevel gears 207. The upper and lower device boxes 205 provide external protection for the second bevel gears 207 and the first bevel gears 206 inside. When the first rotating rod 202 is driven, the first bevel gears 206 on the outer sides of the upper and lower ends of the first rotating rod 202 rotate synchronously. One first bevel gear 206 meshes with the two second bevel gears 207, driving the two second bevel gears 207 to rotate inside the device box 205, thus transmitting power from the first rotating rod 202 to the second bevel gears 207.

[0037] Each of the four second bevel gears 207 has a first connecting rod 208 fixedly connected inside. The other ends of the four first connecting rods 208 are rotatably connected to the front and rear sides of the left side of the housing 1. Driven by the second bevel gears 207, the first connecting rods 208 inside will also rotate synchronously. When the first connecting rods 208 rotate, the other ends of the first connecting rods 208 pass through the front and rear side walls of the housing 1 and support the first connecting rods 208, so that the first connecting rods 208 can rotate stably and in a balanced manner. Two second connecting rings 209 are fixedly connected to the outer side of each first connecting rod 208. A push plate 210 is fixedly connected to the outer side of each second connecting ring 209. When the second bevel gear 207 rotates, it will drive the first connecting rod 208 connected to it to rotate. Two second connecting rings 209 are fixedly connected to the outer side of the first connecting rod 208. A push plate 210 is fixedly connected to the outer side of each second connecting ring 209. As the first connecting rod 208 rotates, the second connecting rings 209 and the push plate 210 rotate accordingly. The pushing action further enhances the mixing effect of the sewage, avoids the situation of local stagnation or uneven mixing of sewage, and prevents some sewage and sediment from remaining in dead corners. It also pushes sewage and impurities through the first baffle 3 and the top second baffle 4 to flow to the next area for treatment.

[0038] like Figure 1 - Figure 9 As shown, a first baffle 3 is fixedly connected to the left side of the inside of the box 1. The left side wall of the first baffle 3 is set on the right side wall of the device box 205. A second baffle 4 is fixedly connected to the inside of the box 1. Guide plates 5 are fixedly connected to the top of both the second baffle 4 and the first baffle 3. The inside of the box 1 is divided into three areas by the first baffle 3 and the second baffle 4 to treat sewage. The guide plates 5 on the top of the first baffle 3 and the second baffle 4 guide the sewage and sediment.

[0039] A control panel 6 is fixedly connected to the front wall of the housing 1. The entire equipment is controlled through the control panel 6. A first conveying pipe 7 is installed in the groove at the bottom left side of the housing 1. The right end of the first conveying pipe 7 is connected to three sewage inlet pipes 8. The top of each of the three sewage inlet pipes 8 is connected to a first nozzle 9. The outer sides of the multiple first nozzles 9 are connected to the bottom wall of the housing 1. The first conveying pipe 7 is connected to the external pipes to transport sewage into the interior of the first conveying pipe 7 and into the equipment. The first conveying pipe 7 is located in the groove at the bottom left side of the housing 1. Its right end is connected to three sewage inlet pipes 8. The top of each sewage inlet pipe 8 is connected to a first nozzle 9. The outer side of the first nozzle 9 penetrates the bottom wall of the housing 1, so that sewage can be sprayed upward from the bottom of the housing 1 in a spraying manner. Through the spraying of the first nozzles 9, the sewage can be distributed relatively evenly at the bottom of the housing 1.

[0040] A guide plate 29 is fixedly connected to the inside of the right side of the tank 1. The left side wall of the guide plate 29 is fixedly connected to the right side wall of the second baffle 4. A drain pipe 30 is connected through the bottom of the right side wall of the tank 1. Drainage holes 31 are provided on both the front and rear sides of the right side of the tank 1. After a series of processes such as stirring, aeration, and scum removal, pollutants in the wastewater are effectively removed. At this time, the wastewater flows to the right side of the tank 1 under the action of the guide plate 29. The treated wastewater is guided to the bottom of the right side of the tank 1. A drain pipe 30 is provided at the bottom of the right side wall of the tank 1 for discharging sludge and other solid waste generated during the treatment process. The drain holes 31 provided on the front and rear sides of the right side of the tank 1 are used to discharge the treated clean water that meets the standards, thus realizing the purification and discharge of wastewater.

[0041] like Figure 1 - Figure 11 As shown, a top box 10 is fixedly connected to the top of the housing 1, and a protective box 11 is fixedly connected to the left side of the front side wall of the top box 10. The top box 10 and the protective box 11 are used to protect the internal device from external damage.

[0042] An air cylinder 12 is provided on the rear side wall of the housing 1. A connecting plate 13 is fixedly connected to the front side wall of the air cylinder 12. The front side wall of the connecting plate 13 is fixedly connected to the rear side wall of the housing 1, thereby fixing the air cylinder 12 to the rear side wall of the housing 1. A first support plate 14 is fixedly connected to the rear side wall of the housing 1. An air pump 15 is fixedly connected to the top of the first support plate 14, thereby supporting and fixing the air pump 15 at the top.

[0043] The output end of the air pump 15 is fixedly connected to a second delivery pipe 16. The top end of the second delivery pipe 16 is connected to the left side wall of the air storage cylinder 12, and the bottom end of the air storage cylinder 12 is connected to an air outlet pipe 17. The front ends of the two air outlet pipes 17 are connected to the middle bottom wall of the tank 1, and the tops of the two air outlet pipes 17 are connected to a second nozzle 18. Air is delivered to the air storage cylinder 12 through the second delivery pipe 16 by the air pump 15. The air storage cylinder 12 is fixed to the rear side wall of the tank 1 by a connecting plate 13. The front ends of the air outlet pipes 17 connected to its bottom end are connected to the middle bottom wall of the tank 1, and the second nozzles 18 connected to the top of the air outlet pipes 17 inject air into the sewage in the form of aeration. The purpose of aeration is to provide sufficient oxygen for aerobic microorganisms, promote the decomposition and metabolism of organic matter in the sewage by microorganisms, and ensure that the air is evenly dispersed in the sewage, thus ensuring the comprehensiveness of the aeration effect.

[0044] The protective box 11 is equipped with a second motor 19. The output end of the second motor 19 is fixedly connected to a second rotating rod 20. The outer sides of the front and rear ends of the second rotating rod 20 are fixedly connected to first spur gears 21. The front and rear side walls of the top box 10 are equipped with rack rings 22. The outer sides of the two first spur gears 21 mesh with the inner left side of the two rack rings 22. The output end of the second motor 19 drives the second rotating rod 20 to rotate inside the top box 10. The two spur gears 21 are connected to the front and rear ends of the second rotating rod 20. The first spur gears 21 on the outer side of the second rotating rod 20 will also rotate synchronously and mesh with the rack rings 22 to drive the rack rings 22 to rotate.

[0045] The top box 10 has a second connecting rod 23 rotatably connected to its inner right side. The front and rear ends of the second connecting rod 23 are fixedly connected to second spur gears 24. The outer sides of the two second spur gears 24 mesh with the inner right sides of the two rack rings 22. By installing the front and rear ends of the second connecting rod 23 inside the top box 10, the second spur gears 24 on the outer side of the second connecting rod 23 are supported. This allows the second spur gears 24 to mesh with the inner right side of the rack rings 22. The first spur gear 21 drives the second spur gears 24 to rotate, and also supports the rack rings 22, enabling the rack rings 22 to operate stably and in a balanced manner. The second spur gears 24 drive the second connecting rod 23 to rotate inside the top box 10.

[0046] Two rack rings 22 are fixedly connected to the outer sides of each rack ring 22. Two connecting blocks 26 are fixedly connected to the inner side walls of each fixed ring 25. A second support plate 27 is fixedly connected to the other side of each pair of connecting blocks 26. A scraper 28 is fixedly connected to the bottom wall of each second support plate 27. The right side wall of each scraper 28 is correspondingly set with the right side guide plate 5. The fixed rings 25 on the outer side of the rack ring 22 rotate synchronously with the rack ring 22. The connecting blocks 26 on the front and rear sides of the second support plate 27 are installed through the holes and grooves on the inner side wall of the fixed ring 25. When the fixed rings 25 rotate, they drive the second support plate 27 to move. When the second support plate 27 moves, the scraper 28 at the bottom of the second support plate 27 scrapes away the impurities carried by the air flotation. The scraper 28 scrapes away the scum on the water surface along the direction of the guide plate 5 at the top of the second baffle 4, and collects the scum in the right side of the tank 1 to prevent the accumulation of scum from affecting the treatment effect and equipment operation.

[0047] It should be noted that this utility model is an upflow integrated sewage treatment device. First, the first motor 201, the second motor 19, the control panel 6 and the air pump 15 are connected to an external power source to supply power to the device.

[0048] First, the medicine is added into the interior of the container 1 through an external dosing device. The multi-layer stirring and mixing mechanism 2 is powered by a first motor 201. When the equipment is started, the first motor 201 begins to run, and its output end drives the first rotating rod 202 connected to it to rotate. The power of the motor is transmitted to each stirring and pushing component. A first connecting ring 203 is fixedly connected to the outer side of the middle of the first rotating rod 202. Each first connecting ring 203 is connected to a stirring rod 204. As the first rotating rod 202 rotates, the first connecting ring 203 rotates accordingly, thereby driving the stirring rod 204 to make a circular motion around the first rotating rod 202. During the rotation, the stirring rod 204 comes into full contact with the wastewater, stirring the medicine and wastewater and ensuring that the different components in the medicine and wastewater are fully mixed.

[0049] A device box 205 is provided on the outer sides of the upper and lower ends of the first rotating rod 202. The first bevel gear 206, which is fixedly connected to the outer sides of the upper and lower ends of the first rotating rod 202, is located inside the device box 205. At the same time, four second bevel gears 207 are provided on the front and rear sides inside the device box 205, and each first bevel gear 206 meshes with two second bevel gears 207 located on the same side.

[0050] When the first rotating rod 202 rotates, the first bevel gear 206 rotates accordingly. Since the first bevel gear 206 meshes with the second bevel gear 207, the rotation of the first bevel gear 206 will drive the meshing second bevel gear 207 to rotate. The bevel gear transmission method realizes the transmission of power from the first rotating rod 202 to the second bevel gear 207 and changes the transmission direction, so that the second bevel gear 207 can rotate in a suitable direction and speed. The first connecting rod 208 is fixedly connected inside each of the four second bevel gears 207, and the other end of the first connecting rod 208 is rotatably connected to the front and rear sides of the left side of the housing 1.

[0051] When the second bevel gear 207 rotates, it drives the first connecting rod 208 connected to it to rotate. Two second connecting rings 209 are fixedly connected to the outer side of the first connecting rod 208, and a push plate 210 is fixedly connected to the outer side of each second connecting ring 209. As the first connecting rod 208 rotates, the second connecting rings 209 and the push plate 210 rotate accordingly. During rotation, the push plate 210 pushes the wastewater, causing it to flow in different directions within the tank 1. This pushing action further enhances the mixing effect of the wastewater, preventing localized stagnation or uneven mixing. Simultaneously, the pushing action of the push plate 210 helps ensure sufficient contact between the wastewater and treatment agents and microorganisms, improving the decomposition efficiency of pollutants by microorganisms during biological treatment and the reaction effect of agents during chemical treatment.

[0052] After mixing, the wastewater is conveyed to the next area via the push plate 210 through the first baffle 3 and the top guide plate 5. Some suspended solids, sediments, and impurities in the wastewater will adhere to the air bubbles and gradually float to the surface to form scum. At this time, the scum treatment mechanism starts to work.

[0053] The second motor 19 inside the protective box 11 starts, and its output drives the second rotating rod 20 to rotate. The first spur gear 21 on the outer side of the front and rear ends of the second rotating rod 20 meshes with the left inner side of the rack ring 22 on the front and rear side walls inside the top box 10. At the same time, the second spur gear 24 on the second connecting rod 23 meshes with the right inner side of the rack ring 22. When the second rotating rod 20 rotates, the meshing transmission between the gears and the rack ring 22 drives the rack ring 22 to make circular motion inside the top box 10. The fixing ring 25 on the outer side of the rack ring 22 moves together with the rack ring 22. The connecting block 26 connected to the inner side wall of the fixing ring 25 drives the second support plate 27 to move, and the scraper 28 on the bottom wall of the second support plate 27 also moves accordingly. The scraper 28 scrapes off the scum on the water surface along the direction of the guide plate 5, collects the scum, and prevents the accumulation of scum from affecting the treatment effect and equipment operation.

[0054] After a series of processes including mixing, aeration, and scum removal, pollutants in the wastewater are effectively removed. At this point, the wastewater flows to the right side of the tank 1 under the action of the guide plate 29. The guide plate 29 is connected to a second baffle 4 on its left side, guiding the treated wastewater to the bottom right side of the tank 1. A drain pipe 30 is installed at the bottom of the right side wall of the tank 1 to discharge sludge and other solid waste generated during the treatment process. Drainage holes 31 are located on the front and rear sides of the right side of the tank 1 to discharge treated clean water that meets standards, thus achieving wastewater purification and discharge.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
