Description

Technical Field

[0001] The present application relates to the field of water treatment technology, and in particular to an integrated water treatment method and equipment thereof. Background Art

[0002] The working principle of an integrated water treatment system usually includes multiple stages such as physical treatment, chemical treatment and biological treatment. The physical treatment stage mainly removes solid impurities and suspended matter in the water through equipment such as screens and grit chambers; the chemical treatment stage involves processes such as coagulation, sedimentation and filtration to remove soluble substances and colloidal substances in the water; the biological treatment stage uses the metabolism of microorganisms to degrade organic matter and nutrients such as nitrogen and phosphorus in the water.

[0003] In the pretreatment stage, it is necessary to use a flocculant and mix the sewage, and then discharge it through a screen to remove floating objects. However, the mixing and stirring method in the prior art is single, resulting in poor mixing effect. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide an integrated water treatment method and equipment thereof, which are used to solve the technical problem in the prior art that the mixing and stirring method is single, resulting in poor mixing effect.

[0005] The above-mentioned purpose of the present application is achieved through the following technical scheme: an integrated water treatment equipment, including a water inlet pipe and a stirring container for stirring sewage and flocculant, the stirring container is fixedly connected with a connecting pipe for connecting the water inlet pipe, a connecting shaft is rotatably arranged on the upper end of the stirring container, a stirring plate is fixedly arranged on the axial surface of the lower end of the connecting shaft, a driving structure for driving the stirring plate to rotate is arranged on the upper end of the connecting shaft, a rotating shell is rotatably arranged inside the stirring container, streamline grooves are evenly opened on the inner side of the rotating shell, and a passage for transporting flocculant is arranged inside the connecting shaft.

[0006] By adopting the above technical solution, after the sewage enters the connecting pipe through the water inlet pipe, the stirring plate is driven to rotate through the driving structure, and the flocculant is added to the inside of the rotating shell through the connecting shaft to stir together. At the same time, during stirring, the sewage will hit the streamline groove, thereby driving the rotating shell to rotate in the stirring container, so that the sewage and flocculant are fully mixed and stirred.

[0007] Furthermore, the driving structure includes a pushing plate fixedly connected to the connecting shaft, the outlet of the communicating pipe is aligned with the pushing plate, and a flow hole for sewage to flow into the interior of the rotating shell is provided at the upper end of the rotating shell.

[0008] By adopting the above technical solution, when sewage enters the connecting pipe through the water inlet pipe, it hits the push plate to drive the connecting shaft to rotate, so that the stirring plate at the bottom rotates at the same time, and the sewage enters the rotating shell through the flow hole and is mixed and stirred.

[0009] Furthermore, an acceleration component for increasing the flow rate of sewage is arranged inside the water inlet pipe close to the connecting pipe.

[0010] Furthermore, the acceleration component includes an acceleration pipe rotatably connected to the inside of the water inlet pipe, an acceleration groove is opened inside the acceleration pipe, the water inlet pipe is in an inverted U shape, and a water pump is installed on one end of the water inlet pipe away from the connecting pipe.

[0011] By adopting the above technical solution, the water pump introduces sewage into the water inlet pipe, and there will be a step difference before reaching the acceleration pipe, so that the water's own gravitational potential energy will impact the acceleration tank, causing the acceleration pipe to rotate, thereby further increasing the speed of water flow entering the connecting pipe and better impacting the push plate.

[0012] Furthermore, a trumpet-shaped open pipe is fixedly provided on the upper end of the acceleration pipe, and the open pipe is rotatably connected to the water inlet pipe.

[0013] By adopting the above technical solution, the setting of the open pipe can prevent sewage from flowing into between the acceleration pipe and the water inlet pipe.

[0014] Furthermore, the flow hole is inclined inward, and a release hole is provided on the side of the bottom of the connecting shaft.

[0015] By adopting the above technical solution, compressed air can also be added to the connecting shaft before adding flocculants. When the sewage flows into the rotating shell along the inclined flow holes, flocculants and compressed air will flow out of the release holes around the connecting shaft, thereby continuously rotating in contact with the sewage, making it easier for the sediment in the water to coagulate.

[0016] Furthermore, a flow plate fixedly connected to the rotating shell is arranged in the flow line groove, and a water hole is arranged on the stirring plate.

[0017] By adopting the above technical solution, when the connecting shaft and the rotating shell rotate, the sewage will become more chaotic due to the setting of the flow plate and the water holes, so that the sewage water, flocculant and compressed air are mixed more evenly.

[0018] Furthermore, the connecting shaft extends to the outside of the bottom of the rotating shell, the bottom of the connecting shaft is fixedly connected with a driving tooth, and the bottom of the rotating shell is fixedly provided with a driven tooth engaged with the driving tooth.

[0019] By adopting the above technical solution, when the connecting shaft rotates, it will drive the active gear, so that its driven gear rotates together, thereby ensuring that the rotation frequency of the stirring plate and the rotating shell is the same. At the same time, when the driven gear is driven by the active gear, the stirring plate and the rotating shell rotate in opposite directions, which will further improve the mixing effect.

[0020] Furthermore, a discharge hole for transporting mixed sewage is provided at the bottom of the rotating shell, and a drainage pipe is connected to the bottom of the stirring container, and a stop valve is provided on the drainage pipe.

[0021] By adopting the above technical solution, the mixed sewage is discharged through the drainage pipe and enters the next step of treatment.

[0022] Furthermore, an integrated water treatment method is applied to an integrated water treatment device described in any one of the above technical solutions, comprising the following steps: S1. Start the water pump to introduce the sewage to be treated through the water inlet pipe; S2. After the sewage enters the water inlet pipe, due to the inverted U-shape of the water inlet pipe, the sewage will experience a step difference before reaching the acceleration pipe. The gravitational potential energy is used to accelerate the impact of the acceleration tank in the acceleration pipe, causing the acceleration pipe to rotate, further increasing the water flow speed; S3. The trumpet-shaped opening pipe at the upper end of the acceleration pipe ensures that sewage will not leak into the gap between the acceleration pipe and the water inlet pipe; S4. The accelerated sewage passes through the connecting pipe and directly hits the push plate. The push plate is fixedly connected to the connecting shaft, so it will drive the connecting shaft and the stirring plate at the lower end to start rotating. At the same time, the flocculant is added to the rotating shell through the transportation passage inside the connecting shaft. If necessary, compressed air can also be added at the same time; S5. The sewage enters the rotating shell through the inclined flow holes and mixes with the flocculant and compressed air. The release holes around the connecting shaft release the flocculant and compressed air, which continuously rotate in contact with the sewage, making it easier for the sediment in the water to form clots. S6. The design of the water holes on the stirring plate and the flow grooves and flow plates in the rotating shell makes the sewage more chaotic in the stirring container, ensuring that the sewage, flocculant and compressed air are mixed more evenly; S7. When sewage hits the flow trough, it drives the rotating shell to rotate in the mixing container. At the same time, the active gear at the bottom of the connecting shaft meshes with the driven gear on the outside of the rotating shell, ensuring that the stirring plate and the rotating shell rotate at the same frequency but in opposite directions, further improving the mixing effect; S8. After mixing, the sewage flows into the bottom of the mixing container through the discharge hole at the bottom of the rotating shell, and then is discharged through the connected drainage pipe. A stop valve is provided on the drainage pipe to control the discharge.

[0023] By adopting the above technical solution, the sewage to be treated is introduced through the water inlet pipe by starting the water pump, and the inverted U-shaped design of the water inlet pipe is used to make the sewage experience a step difference before reaching the acceleration pipe, and use the gravitational potential energy to accelerate and hit the acceleration groove in the acceleration pipe, thereby further increasing the water flow speed. The trumpet-shaped opening pipe at the upper end of the acceleration pipe ensures that the sewage will not leak into the gap between the acceleration pipe and the water inlet pipe. The accelerated sewage directly hits the push plate through the connecting pipe, and the push plate is fixedly connected to the connecting shaft, so it will drive the connecting shaft and the stirring plate at its lower end to start rotating. At the same time, the flocculant is added to the rotating shell through the transport passage inside the connecting shaft, and compressed air can also be added at the same time if necessary. The sewage enters the rotating shell along the inclined flow hole and mixes with the flocculant and compressed air. The release holes around the connecting shaft will release the flocculant and compressed air, which will continuously contact and rotate with the sewage, making it easier for the sediment in the water to form clots. The water holes on the stirring plate, the streamline grooves in the rotating shell and the design of the flow plate, as well as the relative rotation of the stirring plate and the rotating shell (same frequency but opposite direction), work together to form a complex flow pattern in the mixing container, thereby ensuring that the sewage, flocculant and compressed air are mixed more evenly. This efficient mixing and uniform dispersion makes it easier for the sediment in the water to form clots, improving the efficiency of subsequent treatment steps such as sedimentation and filtration. At the same time, the gravitational potential energy of the sewage is used to accelerate the impact into the acceleration pipe, which not only increases the water flow rate, but also reduces additional energy consumption. The stop valve installed on the drainage pipe can effectively control the discharge of sewage and prevent accidental leakage and environmental pollution.

[0024] In summary, the present application includes the following beneficial technical effects: the device drives the stirring plate to rotate through the driving structure, and at the same time uses the connecting shaft to add the flocculant to the inside of the rotating shell for stirring. This design ensures that the sewage and the flocculant can be fully mixed in a short time, thereby improving the mixing efficiency. During the stirring process, the sewage will hit the streamline groove on the inside of the rotating shell, thereby driving the rotating shell to rotate in the stirring container. This rotation further promotes the mixing of the sewage and the flocculant, making the mixing more uniform. The kinetic energy of the flow of the sewage is used to drive the rotating shell to rotate, thereby achieving effective energy utilization and further reducing energy consumption.

DETAILED DESCRIPTION

[0027] The present application is further described in detail below with reference to the accompanying drawings.

[0028] Example, see Figure 1 as well as Figure 2 An integrated water treatment device includes a water inlet pipe 3 and a stirring container 1 for stirring sewage and flocculants. A connecting pipe 10 for connecting the water inlet pipe 3 is fixedly connected to the stirring container 1. A connecting shaft 2 is rotatably arranged on the upper end of the stirring container 1. A stirring plate 22 is fixedly arranged on the axial surface of the lower end of the connecting shaft 2. A driving structure for driving the stirring plate 22 to rotate is arranged on the upper end of the connecting shaft 2. A rotating shell 11 is rotatably arranged inside the stirring container 1. Streamline grooves 12 are evenly opened on the inner side of the rotating shell 11. A passage for transporting flocculants is arranged inside the connecting shaft 2. After the sewage enters the connecting pipe 10 along the water inlet pipe 3, the stirring plate 22 is driven to rotate by the driving structure, and the flocculant is added to the rotating shell 11 through the connecting shaft 2 to stir together. At the same time, the sewage will hit the streamline groove 12 during stirring, thereby driving the rotating shell 11 to rotate in the stirring container 1, so that the sewage and the flocculant are fully mixed and stirred.

[0029] In this embodiment, refer to Figure 3 The driving structure includes a push plate 23 fixedly connected to the connecting shaft 2, the outlet of the connecting pipe 10 is aligned with the push plate 23, and the upper end of the rotating shell 11 is provided with a flow hole 17 for sewage to flow into the rotating shell 11. When the sewage enters the connecting pipe 10 through the water inlet pipe 3, it hits the push plate 23, thereby driving the connecting shaft 2 to rotate, so that the stirring plate 22 at the bottom rotates at the same time, and the sewage enters the rotating shell 11 through the flow hole 17 and is mixed and stirred.

[0030] In this embodiment, an acceleration component for increasing the flow rate of sewage is arranged inside the water inlet pipe 3 near the connecting pipe 10, and the acceleration component includes an acceleration pipe 32 rotatably connected inside the water inlet pipe 3, and an acceleration groove 33 is arranged inside the acceleration pipe 32. The water inlet pipe 3 is in an inverted U shape, and a water pump 31 is installed on one end of the water inlet pipe 3 away from the connecting pipe 10. The water pump 31 introduces sewage into the water inlet pipe 3, and there is a step difference before reaching the acceleration pipe 32, so that the gravity potential energy of the water itself will impact the acceleration groove 33, so that the acceleration pipe 32 rotates, thereby further increasing the speed of water entering the connecting pipe 10 and better impacting the push plate 23.

[0031] In this embodiment, a trumpet-shaped open pipe 34 is fixedly provided at the upper end of the acceleration pipe 32, and the open pipe 34 is rotatably connected to the water inlet pipe 3. The setting of the open pipe 34 can prevent sewage from flowing into the space between the acceleration pipe 32 and the water inlet pipe 3.

[0032] In this embodiment, the flow hole 17 is tilted inward, and release holes 21 are evenly opened on the side of the connecting shaft 2. Before adding flocculant, compressed air can also be added to the connecting shaft 2. When the sewage flows into the rotating shell 11 along the tilted flow hole 17, flocculant and compressed air will flow out of the release holes 21 around the connecting shaft 2, so that the sewage is continuously in contact with the sewage and rotates, making it easier for the sediment in the water to coagulate.

[0033] In this embodiment, a flow plate 13 fixedly connected to the rotating shell 11 is provided in the flow line groove 12, and a water hole 221 is provided on the stirring plate 22. When the connecting shaft 2 and the rotating shell 11 rotate, the sewage will be more chaotic with the setting of the flow plate 13 and the water hole 221, so that the sewage, flocculant and compressed air are mixed more evenly.

[0034] In this embodiment, refer to Figure 4 The connecting shaft 2 extends to the outside of the bottom of the rotating shell 11, and a driving gear 15 is fixedly connected to the bottom of the connecting shaft 2. A driven gear 16 engaged with the driving gear 15 is arranged on the outside of the rotating shell 11. When the connecting shaft 2 rotates, the driving gear 15 will be driven, so that the driven gear 16 will rotate together, thereby ensuring that the rotation frequency of the stirring plate 22 and the rotating shell 11 is the same. At the same time, when the driven gear 16 is driven by the driving gear 15, the stirring plate 22 and the rotating shell 11 rotate in opposite directions, which will further improve the mixing effect.

[0035] In this embodiment, a discharge hole 14 for transporting mixed sewage is provided at the bottom of the rotating shell 11, and a drainage pipe 4 is connected to the bottom of the mixing container 1, and a stop valve is provided on the drainage pipe. The mixed sewage is discharged through the drainage pipe 4 and enters the next step of treatment.

[0036] In this embodiment, an integrated water treatment method is applied to any one of the integrated water treatment devices in the above technical solutions, comprising the following steps: S1, start the water pump 31 to introduce the sewage to be treated through the water inlet pipe 3; S2. After the sewage enters the water inlet pipe 3, since the water inlet pipe 3 is in an inverted U shape, the sewage will experience a step difference before reaching the acceleration pipe 32. The sewage will use the gravity potential energy to accelerate and hit the acceleration groove 33 in the acceleration pipe 32, causing the acceleration pipe 32 to rotate, further increasing the water flow speed. S3, the trumpet-shaped opening pipe 34 at the upper end of the accelerating pipe 32 ensures that sewage will not leak into the gap between the accelerating pipe 32 and the water inlet pipe 3; S4. The accelerated sewage passes through the connecting pipe 10 and directly hits the push plate 23. The push plate 23 is fixedly connected to the connecting shaft 2, so it drives the connecting shaft 2 and the stirring plate 22 at the lower end to start rotating. At the same time, the flocculant is added to the rotating shell 11 through the transportation passage inside the connecting shaft 2. If necessary, compressed air can also be added at the same time; S5, the sewage enters the rotating shell 11 through the inclined flow hole 17, and is mixed with the flocculant and compressed air. The release holes 21 around the connecting shaft 2 release 21 the flocculant and compressed air, which are in continuous contact with the sewage and rotate, making it easier for the sediment in the water to form clots; S6. The design of the water holes 221 on the stirring plate 22 and the streamline grooves 12 and the flow plate 13 in the rotating shell 11 makes the sewage more chaotic in the stirring container 1, ensuring that the sewage, flocculant and compressed air are mixed more evenly; S7. When the sewage hits the flow groove 12, it drives the rotating shell 11 to rotate in the mixing container 1. At the same time, the active gear 15 at the bottom of the connecting shaft 2 is engaged with the driven gear on the outside of the rotating shell 11, ensuring that the stirring plate 22 and the rotating shell 11 rotate at the same frequency but in opposite directions, further improving the mixing effect; S8. After mixing, the sewage flows into the bottom of the mixing container 1 through the discharge hole 14 at the bottom of the rotating shell 11, and then is discharged through the connected drainage pipe 4. A stop valve is provided on the drainage pipe 4 to control the discharge.

[0037] By starting the water pump 31, the sewage to be treated is introduced through the water inlet pipe 3, and the inverted U-shaped design of the water inlet pipe 3 is used to make the sewage experience a step difference before reaching the acceleration pipe 32, and use the gravitational potential energy to accelerate and hit the acceleration groove 33 in the acceleration pipe 32, further increasing the water flow speed. The trumpet-shaped opening pipe 34 at the upper end of the acceleration pipe 32 ensures that the sewage will not leak into the gap between the acceleration pipe 32 and the water inlet pipe 3. The accelerated sewage directly hits the push plate 23 through the connecting pipe 10, and the push plate 23 is fixedly connected to the connecting shaft 2, so that the connecting shaft 2 and the stirring plate 22 at the lower end thereof will start to rotate. At the same time, the flocculant is added to the inside of the rotating shell 11 through the transportation passage inside the connecting shaft 2, and compressed air can also be added at the same time if necessary. The sewage enters the inside of the rotating shell 11 along the inclined flow hole 17, mixes with the flocculant and compressed air, and the release holes 21 around the connecting shaft 2 release 21 flocculants and compressed air, which are continuously in contact with the sewage and rotate, making it easier for the sediment in the water to form clots. The design of the water holes 221 on the stirring plate 22, the streamline grooves 12 in the rotating shell 11 and the flow plate 13, as well as the relative rotation of the stirring plate 22 and the rotating shell 11 (same frequency but opposite direction), act together on the sewage to form a complex flow pattern in the stirring container 1, thereby ensuring that the sewage, flocculant and compressed air are mixed more evenly. This efficient mixing and uniform dispersion makes it easier for the sediment in the water to form clots, improving the efficiency of subsequent treatment steps such as sedimentation and filtration. At the same time, the gravitational potential energy of the sewage is used to accelerate the impact into the acceleration pipe 32, which not only increases the water flow rate, but also reduces additional energy consumption. The stop valve provided on the drainage pipe 4 can effectively control the discharge of sewage to prevent accidental leakage and environmental pollution.

[0038] Specific implementation process: First, start the pump 31 to suck the sewage to be treated from one end of the water inlet pipe 3. After the sewage enters the water inlet pipe 3, due to the inverted U-shaped shape of the water inlet pipe 3, it will experience a step difference before reaching the acceleration pipe 32. The step difference is used to give the sewage a certain gravitational potential energy. When the sewage hits the acceleration tank 33 in the acceleration pipe 32, it will drive the acceleration pipe 32 to rotate, and at the same time further increase the speed of the water flow. The accelerated sewage passes through the connecting pipe 10 and directly hits the push plate 23 fixedly connected to the connecting shaft 2. Since the push plate 23 is fixedly connected to the connecting shaft 2, the impact will drive the connecting shaft 2 and the stirring plate 22 at its lower end to start rotating. While the sewage hits the push plate 23 and drives the stirring plate 22 to rotate, the flocculant is added to the rotating shell 11 through the transportation path inside the connecting shaft 2. If necessary, compressed air can also be added at the same time. These substances will enter the rotating shell 11 together with the flow of sewage. The sewage enters the rotating shell 11 along the inclined flow hole 17 and mixes with the flocculant and compressed air. The release holes 21 around the connecting shaft 2 will release more flocculants and compressed air, which will continuously contact and rotate with the sewage, making it easier for the sediment in the water to form clots. During the rotation of the connecting shaft 2 and the rotating shell 11, the design of the water holes 221 on the stirring plate 22, the streamline grooves 12 and the flow plate 13 in the rotating shell 11, and the relative rotation of the stirring plate 22 and the rotating shell 11 (the active meshing teeth 15 at the bottom of the connecting shaft 2 are engaged with the driven meshing teeth on the outside of the rotating shell 11 to ensure that the stirring plate 22 and the rotating shell 11 rotate at the same frequency but in opposite directions) act together on the sewage, so that it forms a complex flow pattern in the mixing container 1, thereby ensuring that the sewage, flocculant and compressed air are mixed more evenly. After mixing, the sewage flows into the bottom of the mixing container 1 through the discharge hole 14 at the bottom of the rotating shell 11, and then is discharged through the connected drainage pipe 4. The drainage pipe is provided with a stop valve to control the discharge speed and discharge time of the sewage. Finally, the discharged mixed sewage enters the next treatment process, such as sedimentation, filtration, etc., to further purify the water quality.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
