Description

Technical Field

[0001] This invention belongs to the technical field of aeration treatment devices, and relates to an aeration treatment device for industrial wastewater in isooctane production. Background Technology

[0002] Isooctane is an excellent gasoline additive, primarily used to increase the octane rating of gasoline. Its production process generates a large amount of wastewater. This wastewater generally requires pretreatment, anaerobic biological treatment, aerobic biological treatment, and advanced treatment before discharge. Aerobic biological treatment involves injecting gas into the wastewater through aeration devices to provide sufficient oxygen for aerobic microorganisms, promoting their degradation of organic pollutants.

[0003] Traditional aeration devices typically inject gas into wastewater using fixed aeration heads or pipes. These devices suffer from short bubble residence times and low gas utilization rates; some bubbles float to the surface without participating in the reaction, wasting aeration gas and reducing wastewater treatment efficiency. Furthermore, some current bubble collection structures lack effective bubble-waste separation, easily contaminating the collected gas with significant amounts of wastewater, thus affecting bubble recovery efficiency.

[0004] To address the aforementioned problems, this invention proposes an industrial wastewater aeration treatment device for isooctane production. Summary of the Invention

[0005] To address the problems existing in the background art, the present invention proposes an industrial wastewater aeration treatment device for isooctane production.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An industrial wastewater aeration treatment device for isooctane production includes a tank, a collection box, and a baffle plate. An aeration pipe is installed at the bottom of the tank. A rotating shaft is rotatably mounted inside the tank, and a rotating component is mounted on the rotating shaft. One end of the collection box is connected to a connecting rod, which is rotatably connected to the rotating component via a shaft. Multiple through holes are opened on the lower end face of the collection box, and a collection chamber is opened inside the collection box. A piston plate is elastically slidably mounted inside the collection chamber. The flow-limiting plate is slidably disposed on the upper end surface of the collection box; the piston plate and the flow-limiting plate are linked together; a drainage component is provided at the end of the collection box away from the rotating shaft; The rotating shaft drives the collection box to rotate, and the collection box is in a horizontal state under the action of centrifugal force. The baffle plate slides along the collection box under the resistance of the water flow, which causes the piston plate to slide away from the through hole, and the air bubbles and sewage are sucked into the collection chamber. Under the action of centrifugal force, the sewage flows to the end of the collection box away from the rotating shaft and is discharged through the drain. The speed of the collection box rotating around the rotating shaft gradually decreases, and the collection box rotates downward around the shaft. The piston plate slides towards the through hole, which in turn discharges the air bubbles in the collection chamber.

[0007] Furthermore, the flow-blocking plate is provided with an inclined guide groove, and the piston plate is fixedly connected to a rectangular rod. One end of the rectangular rod extending outside the collection chamber is connected to a sliding rod, which is slidably disposed within the guide groove.

[0008] Furthermore, the drainage component includes a channel located at the end of the collection tank away from the rotating shaft, with one end of the channel communicating with the collection chamber and the other end of the channel communicating with the pool body.

[0009] Furthermore, a venturi tube is provided at the end of the collection box away from the rotating shaft, and the end of the channel away from the collection cavity is connected to the throat of the venturi tube.

[0010] Furthermore, the rotating component is fixedly mounted with a hinge seat, the shaft is rotatably mounted on the hinge seat, the hinge seat has a limit groove, the shaft is fixedly connected to a limit block, and the limit block is slidably disposed in the limit groove.

[0011] Furthermore, the outer circumference of the rotating shaft is provided with multiple slots; the rotating component is provided with a first sliding cavity, and a locking block is elastically slidably disposed in the first sliding cavity; the locking block is fixedly connected to a magnet, and a first iron block is fixed to one end of the first sliding cavity near the rotating shaft; when the magnet is attracted to the first iron block, the locking block is inserted into the slot, and the rotating shaft drives the rotating component to rotate through the locking block; a second iron block is connected to one end of the first sliding cavity away from the rotating shaft; the locking block and the flow deflector are linked together.

[0012] Furthermore, the rotating component has a second sliding cavity that communicates with the first sliding cavity, a sliding plate is slidably disposed in the second sliding cavity, and a second spring is fixedly connected between the sliding plate and the locking block; The rotating component has a second piston cavity that communicates with the second sliding cavity, and the sliding plate is fixedly connected to the second piston rod; one end of the second piston rod is sealed and slidably disposed in the second piston cavity. The collection box has a T-shaped groove, and a T-shaped slider fixedly connected to the baffle plate is slidably disposed in the T-shaped groove; the collection box has a first piston chamber and a first extrusion liquid channel; a first piston rod is slidably disposed in the first piston chamber, and one end of the first piston rod is fixedly connected to the T-shaped slider; one end of the first extrusion liquid channel is connected to the first piston chamber, and the other end of the first extrusion liquid channel is connected to a metal bellows; the rotating part has a second extrusion liquid channel connected to the second piston chamber, and the end of the metal bellows away from the collection box is connected to the second extrusion liquid channel.

[0013] Furthermore, a stirring blade is installed at the bottom of the rotating shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The rotating shaft drives the collection tank to rotate, causing it to reach a horizontal position under centrifugal force. The baffle plate slides along the collection tank due to the resistance of the water flow, which in turn moves the piston plate away from the through hole, collecting air bubbles that are about to float to the surface. Wastewater entering the collection tank flows towards the end away from the rotating shaft under centrifugal force and flows out through the channel. As the rotation speed of the collection tank gradually decreases, the collection tank rotates downwards around the shaft under its own gravity. Simultaneously, the resistance on the baffle plate decreases, causing the piston plate to move closer to the through hole, allowing air bubbles in the collection chamber to enter the tank body. This achieves the recovery and reuse of air bubbles, reduces gas waste, and improves wastewater treatment efficiency.

[0015] 2. When the piston plate slides to the end of the collection chamber furthest from the through hole, the locking block automatically disengages from the slot. Without the drive of the rotating shaft, the rotation speed of the collection box gradually decreases. When the piston plate moves to the end near the through hole, the locking block automatically inserts into the slot, allowing the rotating shaft to drive the collection box to rotate synchronously. This achieves automatic bubble recycling, further improving the efficiency of bubble collection and recycling. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-10 The diagram shows an industrial wastewater aeration treatment device for isooctane production.

[0020] Example 1: The technical solution adopted in this invention is as follows: An industrial wastewater aeration treatment device for isooctane production, comprising a tank 1, a collection box 17, and a flow baffle 26. Figure 1 As shown, multiple aeration pipes 3 are installed at the bottom of the tank body 1, and an air inlet pipe 2 connected to the aeration pipes 3 is opened at the bottom of the tank body 1. A drain pipe 4 is installed at the bottom of the tank body 1, and a valve 5 is installed on the drain pipe 4.

[0021] A mounting bracket 6 is fixedly installed at the upper end of the pool body 1, and a rotating shaft 8 is vertically rotatably mounted on the mounting bracket 6. A motor 7 is fixedly installed on the mounting bracket 6, and the output shaft of the motor 7 is fixedly connected to the rotating shaft 8.

[0022] A stirring blade 9 is fixedly installed at the bottom of the rotating shaft 8. When the rotating shaft 8 drives the stirring blade 9 to rotate, it stirs the sewage in the tank 1.

[0023] A rotating component 11 is mounted on the rotating shaft 8, and a hinge seat 12 is fixedly connected to the rotating component 11. A connecting rod 13 is fixedly connected to one end of the collection box 17, and a shaft 14 is fixedly connected to the end of the connecting rod 13 away from the collection box 17. The shaft 14 is rotatably mounted on the hinge seat 12. The shaft 14 is set perpendicular to the rotating shaft 8.

[0024] like Figure 3 As shown, a limiting groove 15 is provided on the hinge seat 12, and a limiting block 16 is slidably disposed in the limiting groove 15. The limiting block 16 is fixedly connected to the shaft 14. When the limiting block 16 is at one end of the limiting groove 15, the collection box 17 is in a horizontal state. When the limiting block 16 is at the other end of the limiting groove 15, the end of the collection box 17 away from the rotating shaft 8 tilts downward. At this time, the end of the collection box 17 away from the rotating shaft 8 is above the stirring blade 9, avoiding mutual interference between the stirring blade 9 and the collection box 17.

[0025] The collection tank 17 has a collection chamber inside. Multiple through holes 18 communicating with the collection chamber are provided on the lower end face of the collection tank 17. One-way valves 19 are installed in some of the through holes 18. Wastewater and air bubbles in the tank 1 can enter the collection chamber through the one-way valves 19.

[0026] A piston plate 22 is slidably disposed within the collection chamber. Rectangular rods 23 are fixedly mounted at both ends of the piston plate 22, with the ends of the rectangular rods 23 extending outside the collection chamber. A first spring 24 is fitted onto the rectangular rods 23, and the first spring 24 is fixedly connected between the piston plate 22 and the collection box 17. A sliding rod 25 is fixedly connected to the end of the rectangular rod 23 extending outside the collection chamber.

[0027] The baffle plate 26 is slidably disposed on the upper surface of the collection box 17. Specifically, a T-shaped groove 28 is formed on the upper surface of the collection box 17, and a T-shaped slider 29 adapted to the T-shaped groove 28 is fixedly connected to the baffle plate 26. The T-shaped slider 29 is slidably disposed within the T-shaped groove 28. A guide groove 27 is formed on the baffle plate 26, and a slider 25 is slidably disposed within the guide groove 27. The guide groove 27 is inclined. In this embodiment, the cross-section of the baffle plate 26 is triangular.

[0028] When the baffle plate 26 slides along the collection tank 17, it causes the slide rod 25 to slide along the guide groove 27. When the baffle plate 26 experiences significant resistance from the water flow, as the slide rod 25 slides towards the higher end of the guide groove 27, the slide rod 25, through the rectangular rod 23, drives the piston plate 22 to move away from the through hole 18, compressing the first spring 24. Wastewater and air bubbles in the tank 1 then enter the collection chamber through the through hole 18. When the baffle plate 26 experiences less resistance from the water flow, the piston plate 22, under the action of the first spring 24, slides towards the through hole 18, thereby pushing out air bubbles from the collection chamber. Simultaneously, the piston plate 22, through the rectangular rod 23, drives the slide rod 25 to slide towards the lower end of the guide groove 27, and the baffle plate 26 slides along the upper surface of the collection tank 17.

[0029] A drainage component is provided at the end of the collection box 17 away from the rotating shaft 8.

[0030] The drainage component includes a channel 21, which is located at the end of the collection tank 17 away from the rotating shaft 8. A venturi tube 20 is provided at the end of the collection tank 17 away from the rotating shaft 8. One end of the channel 21 communicates with the throat of the venturi tube 20, and the other end of the channel 21 communicates with the collection chamber. The venturi tube 20 passes through the collection tank 17.

[0031] The sewage entering the collection chamber flows towards the end of the collection chamber away from the rotating shaft 8 under the action of centrifugal force, and flows out through the channel 21 and the venturi tube 20. When the collection box 17 rotates around the rotating shaft 8, the sewage flows through the venturi tube 20, and a negative pressure is generated at the throat of the venturi tube 20, which facilitates the sewage in the collection chamber to flow out through the channel 21.

[0032] Working principle: Initially, the slide bar 25 is at the lower end of the guide groove 27, and the piston plate 22 is at the end of the collection chamber near the through hole 18. The end of the collection box 17 away from the rotating shaft 8 is tilted downward.

[0033] In operation, the wastewater to be aerated is injected into tank 1. Then, gas is transported to aeration pipe 3 through air inlet pipe 2, and the gas is injected into the wastewater through aeration pipe 3 to aerate the wastewater. The gas entering the wastewater forms bubbles and gradually flows upward.

[0034] When motor 7 is started, motor 7 drives shaft 8 to rotate, which in turn drives stirring blade 9 to rotate, thus agitating the wastewater. At the same time, shaft 8 drives rotating component 11 to rotate, causing connecting rod 13, collection box 17, and baffle plate 26 to rotate around shaft 8.

[0035] Under the action of centrifugal force, the collection box 17 rotates upward through the shaft 14 until the collection box 17 is in a horizontal state and the limiting block 16 is at one end of the limiting groove 15.

[0036] When the baffle plate 26 rotates around the rotating shaft 8, the resistance of the water flow causes the baffle plate 26 to slide along the upper end surface of the collection box 17. The slide rod 25 gradually slides towards the higher end of the guide groove 27. The slide rod 25 pulls the piston plate 22 away from the through hole 18 through the rectangular rod 23, thereby allowing the sewage and the air bubbles about to float to the surface to enter the collection chamber through the through hole 18.

[0037] Wastewater entering the collection chamber flows towards the end away from the rotating shaft 8 under centrifugal force and exits through channel 21. Wastewater and air bubbles separate, with the air bubbles floating above the wastewater. As the collection tank 17 rotates around the rotating shaft 8, wastewater passes through the venturi tube 20. This creates a suction force at the throat of the venturi tube 20, causing the wastewater in the collection tank 17 to flow through channel 21 into the venturi tube 20 and then into the pool body 1.

[0038] The suction volume of the collection chamber per unit time is greater than that of the channel 21, which reduces the amount of gas flowing out of the collection chamber through the channel 21, thereby maximizing the amount of gas collected in the collection box 17.

[0039] As the collection box 17 rotates around the shaft 8, the baffle plate 26 gradually slides along the collection box 17, and the piston plate 22 gradually moves towards the upper end of the collection box 17, so that the collection box 17 collects the air bubbles in the sewage.

[0040] As the rotational speed of the collection tank 17 around the rotating shaft 8 gradually decreases, the centrifugal force on the collection tank 17 gradually decreases. This causes the collection tank 17 to rotate downwards around the shaft 14 under its own gravity, resulting in the end of the collection tank 17 away from the rotating shaft 8 tilting downwards. Simultaneously, as the rotational speed of the collection tank 17 around the rotating shaft 8 decreases, the flow velocity of the sewage through the venturi tube 20 decreases, and the suction force of the channel 21 decreases. At the same time, the water flow resistance on the baffle plate 26 decreases, causing the piston plate 22 to move closer to the through hole 18 under the action of the first spring 24, thereby pushing the gas in the collection chamber out through the through hole 18. Since a one-way valve 19 is installed in part of the through hole 18, the gas in the collection chamber cannot be discharged through the one-way valve 19, which helps to slow down the outflow velocity of the bubbles in the collection chamber. Even when the end of the collection tank 17 away from the rotating shaft 8 is at the bottom of the pool body 1, there are still bubbles in the collection chamber. As the piston plate 22 moves, the bubbles in the collection chamber are discharged to the bottom of the pool body 1. Furthermore, when the bubbles are squeezed out through the through hole 18 under the pressure of the piston plate 22, it helps to break larger bubbles.

[0041] Example 2: This example is a further improvement based on Example 1.

[0042] like Figure 9 , Figure 10As shown, multiple slots 10 are formed on the outer circumference of the rotating shaft 8. The rotating component 11 has a first sliding cavity and a second sliding cavity communicating with the first sliding cavity. A locking block 34 is slidably disposed within the first sliding cavity. A sliding plate 39 is slidably disposed within the second sliding cavity, and a second spring 38 is fixedly connected between the sliding plate 39 and the locking block 34. Magnets 35 are fixedly connected to both ends of the locking block 34. A first iron block 36 is fixedly attached to the end of the first sliding cavity closest to the rotating shaft 8. When the magnet 35 attracts the first iron block 36, the locking block 34 inserts into the slot 10, and the rotating shaft 8 drives the rotating component 11 to rotate synchronously via the locking block 34. A second iron block 37 is connected to the end of the first sliding cavity furthest from the rotating shaft 8. When the magnet 35 attracts the second iron block 37, the locking block 34 disengages from the slot 10. Without the drive of the rotating shaft 8, the rotational speed of the collection box 17 gradually decreases. The rotating component 11 has a second piston chamber 40 that communicates with the second sliding chamber, and the sliding plate 39 is fixedly connected to the second piston rod 41. One end of the second piston rod 41 is slidably and sealed within the second piston chamber 40.

[0043] The collection tank 17 has a first piston chamber 30 and a first extrusion fluid channel 32. A first piston rod 31 is slidably and sealed within the first piston chamber 30, with one end of the first piston rod 31 fixedly connected to a T-shaped slider 29. One end of the first extrusion fluid channel 32 communicates with the first piston chamber 30, and the other end of the first extrusion fluid channel 32 communicates with a metal bellows 33. The rotating component 11 has a second extrusion fluid channel 42 communicating with the second piston chamber 40, and the end of the metal bellows 33 furthest from the collection tank 17 communicates with the second extrusion fluid channel 42.

[0044] The first piston chamber 30, the first extrusion fluid channel 32, the metal bellows 33, and the second extrusion fluid channel 42 are filled with extrusion fluid.

[0045] Working principle: Initially, magnet 35 is attracted to the first iron block 36, and the locking block 34 is inserted into the locking slot 10. Slide rod 25 is at the lower end of guide slide 27, and piston plate 22 is at the end of collection chamber near through hole 18. The end of collection box 17 away from rotating shaft 8 is tilted downward.

[0046] In operation, the wastewater to be aerated is injected into tank 1. Then, gas is transported to aeration pipe 3 through air inlet pipe 2, and the gas is injected into the wastewater through aeration pipe 3 to aerate the wastewater. The gas entering the wastewater will gradually flow upward.

[0047] When the motor 7 is started, the motor 7 drives the rotating shaft 8 to rotate, which in turn drives the stirring blade 9 to rotate, thus agitating the wastewater. At the same time, the rotating shaft 8 drives the rotating component 11 to rotate through the locking block 34, causing the connecting rod 13, the collection box 17, and the baffle plate 26 to rotate around the rotating shaft 8.

[0048] Under the action of centrifugal force, the collection box 17 rotates upward through the shaft 14 until the collection box 17 is in a horizontal state and the limiting block 16 is at one end of the limiting groove 15.

[0049] When the baffle plate 26 rotates around the rotating shaft 8, the resistance of the water flow causes the baffle plate 26 to slide along the upper end surface of the collection box 17, and the slide rod 25 slides towards the higher end of the guide groove 27. The slide rod 25 pulls the piston plate 22 away from the through hole 18 through the rectangular rod 23, thereby allowing sewage and air bubbles to enter the collection chamber through the through hole 18.

[0050] Wastewater entering the collection chamber flows towards the end away from the rotating shaft 8 under centrifugal force and exits through channel 21. Wastewater and air bubbles separate, with the air bubbles floating above the wastewater. As the collection tank 17 rotates around the rotating shaft 8, wastewater passes through the venturi tube 20. This creates a suction force at the throat of the venturi tube 20, causing the wastewater in the collection tank 17 to flow through channel 21 into the venturi tube 20 and then into the pool body 1.

[0051] The suction volume of the collection chamber per unit time is greater than that of the channel 21, which reduces the amount of air bubbles flowing out of the collection chamber through the channel 21, thereby maximizing the amount of gas collected in the collection box 17.

[0052] As the collection box 17 rotates around the shaft 8, the baffle plate 26 gradually slides along the collection box 17, and the piston plate 22 gradually moves towards the upper end of the collection box 17, so that the collection box 17 collects the air bubbles in the sewage.

[0053] As the piston plate 22 moves away from the through hole 18, the baffle plate 26 slides along the T-shaped groove 28 via the T-shaped slider 29. The T-shaped slider 29 pushes the first piston rod 31, causing it to slide into the first piston chamber 30, thereby allowing the extruded liquid to enter the second piston chamber 40. The second piston chamber 40, via the second piston rod 41, pulls the sliding plate 39 away from the locking block 34. As the sliding plate 39 stretches the second spring 38, the elastic force of the second spring 38 gradually increases. When the piston plate 22 slides to the end of the collection chamber away from the through hole 18, the elastic force of the second spring 38 causes the magnet 35 to detach from the first iron block 36. Then, under the action of the second spring 38, the locking block 34 moves closer to the sliding plate 39 until the magnet 35 is attracted to the second iron block 37. This causes the locking block 34 to disengage from the locking groove 10.

[0054] Subsequently, the rotating shaft 8 can no longer drive the rotating component 11 to rotate via the locking block 34, causing the rotational speed of the collection box 17 around the rotating shaft 8 to gradually decrease, thus reducing the centrifugal force on the collection box 17. Consequently, the collection box 17 rotates downwards around the shaft 14 under its own gravity, causing the end of the collection box 17 away from the rotating shaft 8 to tilt downwards. Simultaneously, as the rotational speed of the collection box 17 around the rotating shaft 8 decreases, the flow velocity of the sewage through the venturi tube 20 decreases, reducing the suction force of the channel 21. At the same time, the water flow resistance on the baffle plate 26 decreases, causing the piston plate 22 to move closer to the through hole 18 under the action of the first spring 24, thereby pushing the gas in the collection chamber out through the through hole 18. Since a one-way valve 19 is installed in part of the through hole 18, the gas in the collection chamber cannot be discharged through the one-way valve 19, which helps to slow down the outflow speed of the bubbles in the collection chamber. This ensures that when the end of the collection box 17 away from the rotating shaft 8 is at the bottom of the pool body 1, there are still air bubbles in the collection chamber. As the piston plate 22 moves, the air bubbles in the collection chamber are discharged to the bottom of the pool body 1.

[0055] As the piston plate 22 moves closer to the through hole 18, the piston plate 22 causes the slide rod 25 to move towards the lower end of the guide groove 27 via the rectangular rod 23. The flow baffle 26 slides along the T-shaped groove 28 away from the first piston chamber 30, and the T-shaped slider 29 pulls the first piston rod 31, causing the first piston rod 31 to move into the T-shaped groove 28, thereby causing the extruded fluid to flow into the first piston chamber 30 and the extruded fluid in the second piston chamber 40 to flow out. This causes the second piston rod 41 and the slide plate 39 to move closer to the rotating shaft 8. The slide plate 39 pushes the locking block 34 to move closer to the rotating shaft 8, causing the magnet 35 to disengage from the second iron block 37. Until the locking block 34 is inserted into the locking slot 10, the magnet 35 is attracted to the first iron block 36.

[0056] Subsequently, as the rotating shaft 8 rotates, the rotating shaft 8 drives the rotating component 11 to rotate through the locking block 34, and the rotating component 11 drives the collection box 17 to rotate through the connecting rod 13 in order to collect the bubbles.

[0057] In this embodiment, when the piston plate 22 moves to the end of the collection chamber away from the through hole 18, that is, after the collection chamber is full, the locking block 34 automatically disengages from the locking groove 10. This causes the rotation of the collection box 17 to gradually decrease, thereby causing the collection box 17 to rotate downwards around the shaft 14, while simultaneously discharging the air bubbles into the sewage. When the air bubbles in the collection chamber are completely discharged, the locking block 34 automatically inserts into the locking groove 10, causing the rotating shaft 8 to drive the collection box 17 to rotate around the rotating shaft 8 again. This achieves automatic recycling of air bubbles, further improving the efficiency of air bubble collection and recycling, and is beneficial to improving the sewage treatment efficiency.

[0058] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
