Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically a chemical sulfur autotrophic denitrification denitrification reaction device. Background Technology

[0002] Sulfur autotrophic denitrification is a novel denitrification technology that uses sulfur compounds as electron acceptors to reduce nitrogen in nitrates to nitrogen gas, thereby achieving denitrification. This technology can not only effectively remove nitrogen from wastewater, but also reduce the use of chemical agents and lower treatment costs, and is widely used in wastewater treatment, agricultural production and other fields.

[0003] However, existing and above technologies often have the following drawbacks: when microorganisms are mixed with wastewater, they are mostly mixed by the force generated when the wastewater flows in, and then allowed to react fully after a long period of settling. In this process, the mixing effect of the wastewater impact force is poor and the mixing time is long, which is not conducive to the rapid and effective treatment of wastewater.

[0004] Therefore, the present invention provides a chemical sulfur autotrophic denitrification reaction device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A chemical sulfur autotrophic denitrification reaction device of this invention includes a reactor. An outlet is connected through the top of the reactor. A microbial storage tank is connected through a conduit to one side of the reactor. An injection port and a drain port are provided on the surface of the reactor. A servo motor is fixedly connected inside the reactor. A rotating rod is fixedly connected to the output end of the motor. Two sets of stirring blades are hinged to the surface of the rotating rod. Support rods are rotatably connected to the surface of the stirring blades. A guide rail is fixedly connected to the surface of the motor, and a slope is provided on the surface of the guide rail. During operation, denitrifying sulfur bacteria from the storage tank are injected into the storage tank... After the wastewater is placed in the reactor, the motor is turned on, causing the output shaft of the motor to drive the rotating rod to rotate, which in turn drives the stirring blades to rotate. This causes the stirring blades to stir the wastewater in the reactor, and at the same time, the stirring blades cause the wastewater in the reactor to move upwards, while forcing the fan blades to tilt in the opposite direction. As the stirring blades rotate, they also drive the support rod to rotate. At this time, the motor drives the rotating rod to continue rotating. When the support rod rotates to the guide rail position, the slope on the surface of the guide rail will squeeze the upright rod to move upwards, and at the same time, it will cause the stirring blades to swing upwards. Through the cooperation of the stirring blades and the guide rail, the wastewater in the reactor can be further thoroughly mixed with the denitrifying thiobacilli, thereby improving the wastewater treatment efficiency.

[0007] Preferably, the rotating rod surface is provided with a rotating ring, the rotating ring surface is fixedly connected to a crossbar, the other end of the crossbar is fixedly connected to a scraper, the other side of the scraper is in contact with the inner wall of the reactor, and the support rod surface is rotatably connected to a roller. Each set of stirring blades is symmetrically arranged in pairs. During operation, when the rotating rod rotates, it will drive the crossbar to rotate, causing the crossbar to drive the scraper to scrape the inner wall of the reactor. At the same time, after the wastewater is discharged, the scraper can clean the inner wall of the reactor, preventing impurities from adhering to the inner wall of the reactor and making it inconvenient for workers to clean. The symmetrically designed stirring blades can prevent the rotating rod from bending and deforming due to uneven force during stirring.

[0008] Preferably, the crossbar is divided into a fixed bar and a telescopic bar. The fixed bar is fixedly connected to the rotating ring, and the telescopic bar is slidably connected to the fixed bar via a spring. During operation, the spring allows the scraper to fit more closely to the inner wall of the reactor, resulting in better cleaning performance. After the scraper wears down, the spring can move the scraper towards the inner wall of the reactor to compensate for the wear, preventing gaps from forming between the scraper and the inner wall of the reactor, which would cause the scraper to lose its cleaning effect.

[0009] Preferably, the rotating ring is rotatably connected to the surface of the rotating rod, and the rotating rod surface is slidably connected to a retaining shaft via a spring. The inner wall of the rotating ring has multiple retaining grooves relative to the position of the retaining shaft. During operation, when the motor is stirring, the speed is relatively slow, and the retaining shaft retracts into the rotating rod under the restriction of the spring. When cleaning the inner wall of the reactor, the motor speed increases, and the resulting centrifugal force drives the retaining shaft to engage in the retaining grooves, causing the rotating rod to drive the crossbar to rotate. The retaining shaft and retaining grooves can keep the scraper in a stationary state during stirring, avoiding excessive wear.

[0010] Preferably, a connecting rod is fixedly connected to the surface of the rotating rod. The connecting rod is U-shaped, and scrapers are fixedly connected to both ends of the connecting rod. The scraper surface has an angled opening, and a collection groove is formed inside the scraper. An empty groove is formed in the center of the bottom surface of the collection groove, and the empty groove corresponds to the position of the sewage outlet. The bottom surface of the collection groove is an inclined surface sloping towards the empty groove. During operation, the connecting rod can drive the scraper to scrape at the bottom of the reactor to avoid sedimentation and incomplete mixing. When cleaning the reactor, the sewage outlet is opened to allow sewage to be discharged through the sewage outlet. At the same time, the motor reverses, causing the collection groove on the other side of the scraper to scrape up the residual dirt and impurities at the bottom and collect them into the collection groove. When the scraper rotates to the position of the sewage outlet, the motor stops. The dirt in the collection groove is guided into the empty groove through the inclined surface and flows to the sewage outlet through the empty groove. The collection groove on the surface of the scraper can clean the bottom surface of the reactor and avoid residue.

[0011] Preferably, a connecting plate is slidably connected to the surface of the connecting rod via a spring, and a baffle is fixedly connected to the surface of the connecting plate. A groove is provided on the side wall of the collection tank, and the baffle is slidably connected within the groove and passes through the collection tank. The baffle is made of a magnetic material, and a set of magnetic strips is fixedly connected to the bottom surface of the reactor. During operation, when the scraper moves to the drain outlet, the magnetic strips attract the baffle, causing the baffle to move closer to the magnetic strips. At the same time, the spring is compressed to generate elastic force, causing the baffle to close the collection tank, preventing the mud and dirt in the collection tank from flowing out due to inertia, and improving the cleaning efficiency of the scraper. When the scraper moves to a position without magnetic strips, the spring drives the baffle to reset.

[0012] Preferably, the scraper surface is slidably connected to a sliding shaft via a spring, and a fixing plate is fixedly connected to the surface of the sliding shaft. The bottom surface of the storage groove is hollow. A pressure plate is fixedly connected to one side of the baffle. The sliding shaft passes through the pressure plate and is slidably connected to the side wall of the storage groove. The side of the bottom surface of the storage groove that is close to the sliding shaft is made of elastic material. During operation, as the baffle moves toward the magnetic strip, it drives the pressure plate to move. At the same time, the pressure plate presses the fixing plate, causing the fixing plate to drive the sliding shaft to move and compress the spring, generating elastic force. When the baffle moves to the bottom surface of the storage groove and fits against it, the sliding shaft will hit the bottom surface of the storage groove, causing the elastic surface to vibrate. This guides the impurities in the storage groove into the empty groove with the help of the inclined surface.

[0013] Preferably, an elastic water storage box is fixedly connected to the top of the scraper. The surface of the water storage box has several water inlets, and a filter screen is installed inside each water inlet. A water outlet pipe is connected through the bottom of the water storage box, and an elastic membrane with constriction holes is fixedly connected inside the water outlet pipe. During operation, the constriction holes on the surface of the elastic membrane are closed when the pressure plate is not pressing the water storage box. When the pressure plate moves, it will press the water storage box, and the force on the water storage box will open the constriction holes on the surface of the elastic membrane, so that the water in the water storage box will be flushed into the collection tank through the water guide pipe, further cleaning the collection tank.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The chemical sulfur autotrophic denitrification reaction device of the present invention uses the output shaft of a motor to drive a rotating rod to rotate, which in turn drives the stirring blades to rotate. This causes the stirring blades to stir the wastewater in the reactor, and the stirring blades cause the wastewater in the reactor to move upward. At the same time, the stirring blades force the fan blades to tilt in the opposite direction. As the stirring blades rotate, the support rod rotates. At this time, the motor drives the rotating rod to continue rotating. When the support rod rotates to the guide rail position, the slope on the surface of the guide rail will squeeze the upright rod to move upward, and at the same time, it will cause the stirring blades to swing upward. Through the cooperation of the stirring blades and the guide rail, the wastewater in the reactor can be fully mixed with denitrifying sulfur bacteria, thereby improving the wastewater treatment efficiency.

[0016] 2. The chemical sulfur autotrophic denitrification reaction device of the present invention can drive a scraper to scrape the bottom of the reactor through a connecting rod, so as to avoid sedimentation and incomplete mixing. When cleaning the reactor, the drain port is opened to allow the sewage to be discharged through the drain port. At the same time, the motor reverses, so that the collection groove on the other side of the scraper scrapes up the dirt and impurities remaining at the bottom and collects them into the collection groove. When the scraper rotates to the position of the drain port, the motor stops. The dirt in the collection groove is guided into the empty groove through the inclined surface and flows to the drain port through the empty groove. The collection groove opened on the surface of the scraper can clean the bottom surface of the reactor and avoid residue. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example

[0028] like Figures 1 to 7 As shown in the embodiment of the present invention, a chemical sulfur autotrophic denitrification reaction device includes a reactor 1. The top of the reactor 1 is connected to an outlet 2. A microbial storage tank 4 is connected to one side of the reactor 1 through a conduit. The surface of the reactor 1 is provided with a liquid injection port 3 and a sewage discharge port 5. A servo motor 6 is fixedly connected inside the reactor 1. The output end of the motor 6 is fixedly connected to a rotating rod 11. Two sets of stirring blades 10 are hinged to the surface of the rotating rod 11. A support rod 9 is rotatably connected to the surface of the stirring blades 10. A guide rail 15 is fixedly connected to the surface of the motor 6. The surface of the guide rail 15 is provided with a slope.

[0029] During operation, after the denitrifying thiobacillus in storage tank 4 is injected into reactor 1 containing wastewater, motor 6 is turned on. The output shaft of motor 6 drives the rotating rod 11 to rotate, which in turn drives the stirring blade 10 to rotate. The stirring blade 10 stirs the wastewater in reactor 1, and the stirring blade 10 causes the wastewater in reactor 1 to move upward. At the same time, it forces the fan blades to tilt in the opposite direction. As the stirring blade 10 rotates, it drives the support rod 9 to rotate. At this time, motor 6 drives the rotating rod 11 to continue rotating. When the support rod 9 rotates to the position of guide rail 15, the slope on the surface of guide rail 15 will squeeze the upright to move upward, and at the same time drive the stirring blade 10 to swing upward. Through the cooperation of stirring blade 10 and guide rail 15, the wastewater and denitrifying thiobacillus in reactor 1 can be further thoroughly mixed, thereby improving the wastewater treatment efficiency.

[0030] The rotating rod 11 has a rotating ring 21 on its surface, and a crossbar 17 is fixedly connected to the surface of the rotating ring 21. A scraper 13 is fixedly connected to the other end of the crossbar 17. The other side of the scraper 13 is in contact with the inner wall of the reactor 1. A roller 14 is rotatably connected to the surface of the support rod 9. Each set of stirring blades 10 is symmetrically arranged in pairs. During operation, when the rotating rod 11 rotates, it will drive the crossbar 17 to rotate, so that the crossbar 17 drives the scraper 13 to scrape the inner wall of the reactor 1. At the same time, after the wastewater is discharged, the scraper 13 can clean the inner wall of the reactor 1, so as to prevent impurities from adhering to the inner wall of the reactor 1 and making it inconvenient for the staff to clean. The symmetrically designed stirring blades 10 can avoid the rotating rod 11 from bending and deforming due to uneven force during stirring.

[0031] The crossbar 17 is divided into a fixed rod 18 and a telescopic rod 19. The fixed rod 18 is fixedly connected to the rotating ring 21, and the telescopic rod 19 is slidably connected to the fixed rod 18 through a spring. During operation, the spring allows the scraper 13 to fit more closely to the inner wall of the reactor 1, resulting in better cleaning effect. After the scraper 13 wears down, the spring can drive the scraper 13 to move towards the inner wall of the reactor 1 to compensate for the wear, preventing gaps from appearing between the scraper 13 and the inner wall of the reactor 1, which would cause the scraper 13 to lose its cleaning effect.

[0032] The rotating ring 21 is rotatably connected to the surface of the rotating rod 11. The rotating rod 11 is slidably connected to the retaining shaft 20 by a spring. The inner wall of the rotating ring 21 has multiple retaining grooves relative to the position of the retaining shaft 20. During operation, when the motor 6 is stirring, the speed is relatively slow, and the retaining shaft 20 is retracted into the rotating rod 11 under the restriction of the spring. When cleaning the inner wall of the reactor 1, the speed of the motor 6 increases, and the centrifugal force generated drives the retaining shaft 20 to engage in the retaining grooves, so that the rotating rod 11 drives the crossbar 17 to rotate. The retaining shaft 20 and the retaining grooves can keep the scraper 13 in a stationary state during stirring, avoiding excessive wear.

[0033] A connecting rod 8 is fixedly connected to the surface of the rotating rod 11. The connecting rod 8 is U-shaped, and scraper blades 24 are fixedly connected to both ends of the connecting rod 8. The scraper blades 24 have beveled surfaces and collection grooves 29 inside. An empty groove 30 is formed in the center of the bottom surface of the collection groove 29, and the empty groove 30 corresponds to the position of the drain outlet 5. The bottom surface of the collection groove 29 is an inclined surface that slopes towards the empty groove 30. During operation, the connecting rod 8 can drive the scraper blades 24 to scrape at the bottom of the reactor 1 to avoid sedimentation. To prevent incomplete mixing, when cleaning reactor 1, the drain port 5 is opened to allow wastewater to be discharged through the drain port 5. At the same time, the motor 6 reverses, causing the collection groove 29 on the other side of the scraper 24 to scrape up the remaining dirt and impurities at the bottom and collect them into the collection groove 29. When the scraper 24 rotates to the position of the drain port 5, the motor 6 stops. The dirt in the collection groove 29 is guided into the empty groove 30 through the inclined surface and flows to the drain port 5 through the empty groove 30. The collection groove 29 opened on the surface of the scraper 24 can clean the bottom surface of reactor 1 and avoid residue.

[0034] The connecting rod 8 is slidably connected to a connecting plate 22 via a spring. A baffle 23 is fixedly connected to the surface of the connecting plate 22. A groove 31 is provided on the side wall of the receiving groove 29. The baffle 23 is slidably connected within the groove 31 and slides through the receiving groove 29. The baffle 23 is made of a magnetic material. A set of magnetic strips 7 is fixedly connected to the bottom surface of the reactor 1. During operation, when the scraper 24 moves to the position of the drain outlet 5, the magnetic strips 7 will attract the baffle 23, causing the baffle 23 to move closer to the magnetic strips 7. At the same time, it will compress the spring to generate elastic force, causing the baffle 23 to close the receiving groove 29, preventing the mud and dirt in the receiving groove 29 from flowing out due to inertia, and improving the cleaning efficiency of the scraper 24. When the scraper 24 moves to a position without the magnetic strips 7, the spring drives the baffle 23 to reset.

[0035] The scraper 24 is slidably connected to a sliding shaft 28 via a spring. A fixing plate 16 is fixedly connected to the surface of the sliding shaft 28. The bottom surface of the storage groove 29 is hollow. A pressure plate 27 is fixedly connected to one side of the baffle 23. The sliding shaft 28 passes through the pressure plate 27 and is slidably connected to the side wall of the storage groove 29. The bottom surface of the storage groove 29 that is close to the sliding shaft 28 is made of elastic material. During operation, as the baffle 23 moves toward the magnetic strip 7, it drives the pressure plate 27 to move. At the same time, the pressure plate 27 presses the fixing plate 16, causing the fixing plate 16 to drive the sliding shaft 28 to move. Simultaneously, it compresses the spring, generating elastic force. When the baffle 23 moves to be in contact with the bottom surface of the storage groove 29, the sliding shaft 28 will impact the bottom surface of the storage groove 29, causing the elastic surface to vibrate. This, combined with the inclined surface, accelerates the impurities in the storage groove 29 into the empty groove 30.

[0036] The top of the scraper 24 is fixedly connected to an elastic water storage box 25. The surface of the water storage box 25 has several water inlets 26, and a filter screen is installed inside each water inlet 26. The bottom surface of the water storage box 25 is connected to a water outlet pipe, and an elastic membrane with constriction holes is fixedly connected inside the water outlet pipe. During operation, the constriction holes on the surface of the elastic membrane are closed when the pressure plate 27 is not pressing the water storage box 25. When the pressure plate 27 moves, it will press the water storage box 25. The force on the water storage box 25 will open the constriction holes on the surface of the elastic membrane, so that the water in the water storage box 25 will be flushed into the collection tank 29 through the water guide pipe, further cleaning the collection tank 29. Example

[0037] like Figure 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a plurality of plugs 32 are fixedly connected to the side of the pressure plate 27 near the water storage box 25. The plugs 32 are made of rubber and are conical. During operation, the plugs 32 can be inserted into the water inlet 26 when the pressure plate 27 presses down on the water storage box 25, blocking and closing the water inlet 26, avoiding the pressure plate 27 and the water inlet 26 not being tightly closed, thereby increasing the water pressure of the outlet pipe and improving the flushing effect.

[0038] Working principle: After the denitrifying thiobacilli from storage tank 4 are injected into reactor 1 containing wastewater, motor 6 is turned on. The output shaft of motor 6 drives the rotating rod 11 to rotate, which in turn drives the stirring blades 10 to rotate. The stirring blades 10 stir the wastewater in reactor 1, causing the wastewater in reactor 1 to move upwards. At the same time, the stirring blades 10 force the fan blades to tilt in the opposite direction. As the stirring blades 10 rotate, they also drive the support rod 9 to rotate. At this time, motor 6 drives the rotating rod 11 to continue rotating. When the support rod 9 rotates to the position of guide rail 15, the slope on the surface of guide rail 15 will squeeze the upright rod upwards. The rotating rod 11 moves, causing the stirring blade 10 to swing upwards. Through the cooperation of the stirring blade 10 and the guide rail 15, the wastewater in the reactor 1 can be fully mixed with the denitrifying thiobacillus, thereby improving the wastewater treatment efficiency. When the rotating rod 11 rotates, it will drive the crossbar 17 to rotate, causing the crossbar 17 to drive the scraper 13 to scrape the inner wall of the reactor 1. At the same time, after the wastewater is discharged, the scraper 13 can clean the inner wall of the reactor 1, preventing impurities from adhering to the inner wall of the reactor 1 and making it inconvenient for the staff to clean. The symmetrically designed stirring blade 10 can prevent the rotating rod 11 from bending and deforming due to uneven force during stirring.

[0039] The connecting rod 8 can drive the scraper 24 to scrape the bottom of the reactor 1 to avoid sedimentation and incomplete mixing. When cleaning the reactor 1, the drain port 5 is opened to allow sewage to be discharged through the drain port 5. At the same time, the motor 6 will reverse, causing the collection groove 29 on the other side of the scraper 24 to scrape up the residual dirt and impurities at the bottom and collect them into the collection groove 29. When the scraper 24 rotates to the position of the drain port 5, the motor 6 stops. The dirt in the collection groove 29 is guided into the empty groove 30 through the inclined surface and flows to the drain port 5 through the empty groove 30. The collection groove 29 on the surface of the scraper 24 can clean the bottom surface of the reactor 1 to avoid residue. When the scraper 24 moves to the position of the drain port 5, the magnetic strip 7 will attract the baffle 23, causing the baffle 23 to move closer to the magnetic strip 7. At the same time, it will squeeze the spring to generate elastic force, causing the baffle 23 to close the collection groove 29, preventing the mud and dirt in the collection groove 29 from flowing out due to inertia, and improving the cleaning efficiency of the scraper 24.

[0040] When the scraper 24 moves to a position where there is no magnetic strip 7, the spring drives the baffle 23 to reset. As the baffle 23 moves toward the magnetic strip 7, it also drives the pressure plate 27 to move. At the same time, the pressure plate 27 presses the fixing plate 16, causing the fixing plate 16 to drive the sliding shaft 28 to move. Simultaneously, it compresses the spring, generating elastic force. When the baffle 23 moves to a position where it is in contact with the bottom surface of the storage tank 29, the sliding shaft 28 will hit the bottom surface of the storage tank 29, causing the elastic surface to vibrate. This, along with the inclined surface, accelerates the impurities in the storage tank 29 into the empty slot 30. The pores on the surface of the elastic membrane are in a closed state when the pressure plate 27 is not pressing the water storage box 25. As the pressure plate 27 moves, it will press the water storage box 25. The force on the water storage box 25 will open the pores on the surface of the elastic membrane, allowing the water in the water storage box 25 to flow through the water guide pipe into the storage tank 29, further cleaning the storage tank 29.
