Technical Field

[0001] The present invention relates to the technical field of sewage aeration, and in particular to an aeration and sewage purification device for water environment restoration. Background Art

[0002] In order to repair the water environment, biological aeration combination equipment is generally used. Aeration can increase the oxygen content in the water. Aeration also prevents the suspended matter in the pool from sinking and strengthens the contact between the organic matter in the pool and the microorganisms and dissolved oxygen, thereby ensuring that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. The aeration device can effectively solve the problem of water pollution.

[0003] Patent document with publication number CN114573124A discloses a biological aeration combination device for ecological restoration of water environment, including an aeration mechanism and a suspension mechanism. The aeration mechanism includes a driving member and an aeration part. The output shaft of the driving member is coaxially fixedly connected to a rotating shaft located in the aeration part. The rotating shaft is threadedly connected to a negative pressure plate that is vertically slidably connected to the aeration part. A number of air intake check valves are fixedly connected to the negative pressure plate. The air intake check valves are connected to an air path system. In the above invention, the aeration mechanism can be suspended on the water surface by using the suspension mechanism, and the suspension mechanism can be used to adjust the depth of the aeration mechanism into the water to aerate different water levels. The aeration mechanism can also be moved on the water surface by using the suspension mechanism to aerate different positions. However, the biological aeration combination device cannot achieve multi-angle and multi-range aeration during aeration. Summary of the Invention

[0011] The present invention realizes the reciprocating motion of the driven rotary ring along the length direction of the rotary drum by providing a transmission mechanism and a first return spring.

[0013] The present invention sets a first half gear so that when the first half gear is engaged with the upper rack, the expansion ring drives the driven rotating ring to move upward. When the first half gear is not engaged with the upper rack, the driven rotating ring moves downward under the action of the first return spring, thereby realizing the reciprocating motion of the driven rotating ring along the length direction of the rotating cylinder.

[0015] By setting up a sewage lifting shaft, the submersible sewage pump can transport water to the aeration nozzle through the pump liquid channel in the sewage lifting shaft.

[0021] When the second half gear and the lower rack engage, the present invention drives the oscillating ring and its attached aeration and agitation assembly downward. When the second half gear and the lower rack are not engaged, the second return spring causes the oscillating ring and its attached aeration and agitation assembly to return to their original position, enabling reciprocating motion of the aeration and agitation assembly along the length of the rotor and extending the aeration and purification range.

[0027] The present invention provides a second gear shaft, and the outer rotating tube can drive the inner rotating tube to rotate through the second gear shaft. The rotation of the inner rotating tube utilizes the rotation energy of the rotor, and does not require an additional power source. The rotation of the inner rotating tube will drive the aeration stirring tube to rotate, further improving the aeration effect.

DETAILED DESCRIPTION

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0047] like Figure 1 As shown, this embodiment provides an aeration and pollution purification device for water environment remediation, including a float 1, an upper bracket 2 arranged on the top of the float 1, and a lower bracket 3 arranged at the bottom of the float 1. The float 1 is a steel float 1, which is annular and has a through hole in the middle. A plurality of locking rings 9 are provided on the float 1, and the position of the float 1 can be fixed by the locking rings 9. The upper bracket 2 is an inverted U-shape, and the lower bracket 3 is U-shaped. The upper bracket 2 and the lower bracket 3 are both connected to the float 1 by bolts or welding.

[0048] A driving device 5 is fixed to the top of the upper bracket 2 by bolts. The driving device 5 is a motor. A fixing ring 4 is welded to one side of the upper bracket 2. The fixing ring 4 is set on the axis of the through hole. A blower 8 is fixed to the end of the fixing ring 4 away from the driving device 5.

[0049] like Figure 2 、 3As shown, a rotor 6 is rotatably arranged inside the fixed ring 4, and the rotor 6 and the fixed ring 4 are sealed and connected. An annular sewage discharge chamber 26 is provided between the fixed ring 4 and the rotor 6. A sewage discharge hole 25 is provided on the wall of the rotor 6 near the top, and the sewage discharge hole 25 is communicated with the sewage discharge chamber 26. The outer wall of the fixed ring 4 is connected to a sewage storage barrel 27 through a sewage discharge pipe 28, so that impurities in the rotor 6 can enter the sewage storage barrel 27 through the sewage discharge hole 25, the sewage discharge chamber 26, and the sewage discharge pipe 28 in sequence. The sewage storage barrel 27 and the sewage discharge pipe 28 are detachably connected by threads.

[0050] The top end of the rotor 6 extends out of the fixing ring 4 and is provided with bevel gears. The bottom end of the rotor 6 extends toward the lower bracket 3. A dirt lifting shaft 20 is provided to rotate in the rotor 6. The dirt lifting shaft 20 is sealed and connected to the top end of the rotor 6. The top end of the dirt lifting shaft 20 extends out of the rotor 6 and is provided with bevel gears. The output shaft of the driving device 5 is respectively engaged with the bevel gears of the rotor 6 and the bevel gears of the dirt lifting shaft 20, which can drive the rotor 6 and the dirt lifting shaft 20 to rotate in different directions.

[0051] A spiral dirt-lifting sheet 22 is welded on the outer wall of the dirt-lifting shaft 20. The spiral dirt-lifting sheet 22 is spirally arranged around the outer wall of the dirt-lifting shaft 20. The spiral dirt-lifting sheet 22 is clearance-matched with the inner wall of the rotary drum 6. Figure 6 As shown, the bottom end of the rotor 6 is open, and water can enter the rotor 6 from the bottom end of the rotor 6. A plurality of filter holes 24 are provided on the wall of the rotor 6 near the bottom end, and a liquid permeable hole 23 is provided on the spiral sewage lifting sheet 22. It can be understood that when the rotor 6 and the sewage lifting shaft 20 rotate relative to each other, the sewage entering the rotor 6 will be lifted up by the spiral sewage lifting sheet 22. When passing through the filter holes 24, the water in the sewage is discharged from the filter holes 24, and the impurities in the sewage will be further lifted upward by the spiral sewage lifting sheet 22. During the lifting process, the undischarged water can be discharged through the liquid permeable holes 23 on the spiral sewage lifting sheet 22, so that only the impurities in the sewage are lifted to the top of the rotor 6. When the impurities in the sewage are lifted to the top of the rotor 6, under the action of the rotation of the rotor 6, the impurities are thrown into the sewage chamber 26 through the sewage discharge holes 25 and collected into the sewage storage barrel 27 through the sewage discharge pipe 28, thereby achieving the filtration of the sewage. Figure 3 shown.

[0052] like Figure 3 As shown, a pumping channel 21 is provided in the sewage lifting shaft 20, and the pumping channel 21 is arranged along the axis of the rotary drum 6. The top of the sewage lifting shaft 20 is sealed and rotated to set an upper pumping box 29, and the interior of the upper pumping box 29 is connected to the top of the pumping channel 21. Figure 6As shown, a lower pump liquid box 30 is welded on the lower bracket 3, and the bottom end of the sewage lifting shaft 20 extends out of the rotary drum 6 and is rotatably sealed with the lower pump liquid box 30, so that the bottom end of the pump liquid channel 21 is connected with the lower pump liquid box 30, and two submersible sewage pumps 19 are rotatably set near the bottom end of the cylinder wall of the rotary drum 6. The water outlet of the submersible sewage pump 19 is connected with the lower pump liquid box 30 through a pipeline, so that the submersible sewage pump 19 can transport water to the upper pump liquid box 29 through the lower pump liquid box 30 and the pump liquid channel 21 in sequence.

[0053] like Figure 4 As shown, a first limiting ring 12 and a second limiting ring 13 are fixedly provided on the outer wall of the rotary cylinder 6, the first limiting ring 12 is arranged above the second limiting ring 13, and a driven rotary ring 7 is provided between the first limiting ring 12 and the second limiting ring 13. The driven rotary ring 7 is connected to the rotary cylinder 6 along the axial sliding direction, and the driven rotary ring 7 can rotate together with the rotary cylinder 6. The lower end surface of the driven rotary ring 7 is against the second limiting ring 13, and a first return spring 11 is provided between the driven rotary ring 7 and the first limiting ring 12. When the driven rotary ring 7 slides upward, the first return spring 11 will apply a downward force to the driven rotary ring 7. A plurality of aeration nozzles 14 are provided on the outer wall of the driven rotating ring 7. One end of the aeration nozzle 14 is hinged to the driven rotating ring 7. The tube body of the aeration nozzle 14 is connected to the first limiting ring 12 through a connecting rod 15. The two ends of the connecting rod 15 are hinged to the aeration nozzle 14 and the first limiting ring 12 respectively. It can be understood that when the driven rotating ring 7 slides axially, the aeration nozzle 14 will swing up and down.

[0054] like Figure 4 As shown, the driven rotating ring 7 is externally connected to the expansion ring 16 in a sealed rotational manner, so that during the rotation of the driven rotating ring 7, the expansion ring 16 does not rotate with it, and the expansion ring 16 and the driven rotating ring 7 cannot move axially relative to each other. A second annular cavity 18 is provided between the expansion ring 16 and the driven rotating ring 7, and a first annular cavity 17 is provided in the driven rotating ring 7. The first annular cavity 17 and the second annular cavity 18 are connected, and the first annular cavity 17 is connected to the aeration nozzle 14 through a pipeline; Figure 1 As shown, the upper pump liquid box 29 is connected to the second annular cavity 18 in the expansion ring 16 through a pipeline, so that the submersible sewage pump 19 can transport water to the aeration nozzle 14 through the lower pump liquid box 30, the pump liquid channel 21, the upper pump liquid box 29, the second annular cavity 18, and the first annular cavity 17 in sequence.

[0055] like Figure 1 As shown, a fixed ring tube 31 is fixed in the through hole of the floating body 1. The fixed ring tube 31 is annular in shape and is arranged below the expansion ring 16. Figure 11 、 13As shown, a first gear shaft 32 is rotatably provided on the inner wall of the fixed ring tube 31. The first gear shaft 32 is arranged along the central axis of the fixed ring tube 31. Bevel teeth are provided on one end of the first gear shaft 32, and bevel teeth are provided on the outer wall of the rotary drum 6. The bevel teeth of the first gear shaft 32 mesh with the bevel teeth on the outer wall of the rotary drum 6, so that the first gear shaft 32 can be driven to rotate during the rotation of the rotary drum 6. A first half gear 33 is provided on the first gear shaft 32. The first half gear 33 is a gear that is not fully covered with teeth along the circumferential direction. In this embodiment, the first half gear 33 is a gear with half a circle of teeth, that is, the teeth on the first half gear 33 are arranged at 180 degrees; an L-shaped upper rack 35 is provided on the outside of the expansion ring 16. The upper rack 35 meshes with the first half gear 33, so that the first gear shaft 32 is driven to rotate during the rotation of the rotary drum 6. The first half gear 33 of the first gear shaft 32 drives the expansion ring 16 and the driven rotary ring 7 to move upward. Since the first half gear 33 is only provided with half a circle of teeth, after the first half gear 33 drives the expansion ring 16 and the driven rotating ring 7 to move upward for a certain distance, the first half gear 33 is disengaged from the upper rack 35, and the driven rotating ring 7 returns to its original position under the action of the first return spring 11, thereby realizing the axial reciprocating motion of the driven rotating ring 7, causing the aeration nozzle 14 to continuously swing up and down during the rotation of the driven rotating ring 7, thereby realizing synchronous aeration of the aeration nozzle 14 at multiple angles and in multiple ranges.

[0056] like Figure 10 As shown, a stirring gear 41 is fixedly provided outside the rotary drum 6, and the stirring gear 41 is provided below the fixed ring tube 31, and the teeth of the stirring gear 41 are arranged on the outer wall of the stirring gear 41 near the lower end. Figure 5 As shown, a rotation ring 38 and a third limiting ring 40 are provided on the outer wall of the rotary cylinder 6. The third limiting ring 40 is fixedly connected to the rotary cylinder 6. The third limiting ring 40 is provided below the rotation ring 38. A second return spring 39 is provided between the rotation ring 38 and the third limiting ring 40. Figure 14 As shown, the rotational vibration ring 38 includes a middle ring structure and two side ring structures. The two side ring structures are fixedly and symmetrically arranged on both sides of the middle ring structure. Figure 5 、 12 As shown, the middle annular structure of the rotating vibration ring 38 is axially slidably connected to the rotating cylinder 6, and the upper end surface of the middle annular structure of the rotating vibration ring 38 abuts against the lower end surface of the stirring gear 41 under the action of the second return spring 39, and the middle annular structure of the rotating vibration ring 38 and the stirring gear 41 are rotationally connected.

[0057] like Figure 12 、 13As shown, outer rotating tubes 42 are rotatably provided on the two side ring structures of the rotating vibration ring 38. The outer rotating tube 42 and the rotating vibration ring 38 cannot move relative to each other along the axial direction of the outer rotating tube 42. Two inverted L-shaped spoiler rods 49 are fixedly and symmetrically provided at the bottom end of the outer rotating tube 42. A liquid vibrating frame 36 is provided between the two outer rotating tubes 42. The liquid vibrating frame 36 is provided above the rotating vibration ring 38. The liquid vibrating frame 36 is annular and is sleeved on the outer wall of the stirring gear 41 near the upper end. A lower rack 37 is provided on the outer wall of the liquid vibrating frame 36. A second half gear 34 is fixed on the first gear shaft 32. The second half gear 34 and the first half gear 33 are staggered along the axial direction of the first gear shaft 32. The structure of the second half gear 34 is similar to that of the first half gear 33. Both are gears with half-circle teeth, that is, the teeth on the second half gear 34 are arranged at 180°. The lower rack 37 is engaged with the second half gear 34, so that during the rotation of the first gear shaft 32, the liquid vibrating frame 36 can be driven to move downward. As shown Figure 9 As shown, an inner rotating tube 45 is rotatably arranged inside the outer rotating tube 42 , the bottom end of the inner rotating tube 45 extends out of the outer rotating tube 42 and a plurality of aeration stirring tubes 46 are arranged on the outer wall, and the aeration stirring tubes 46 are perpendicular to the inner rotating tube 45 .

[0058] like Figure 12 、 13 As shown, a pressure plate 51 is symmetrically fixed on the outer wall of the vibrating liquid frame 36, and the top end of the outer rotating tube 42 extends upward from the pressure plate 51 and is provided with bevel teeth. The outer rotating tube 42 is rotatably connected to the pressure plate 51, and the outer rotating tube 42 and the pressure plate 51 cannot move relative to each other along the axial direction of the outer rotating tube 42. It can be understood that during the rotation of the first gear shaft 32, the vibrating liquid frame 36 is driven to move downward, the vibrating liquid frame 36 drives the outer rotating tube 42 to move downward, and the outer rotating tube 42 drives the rotary vibration ring 38 to move downward, thereby squeezing the second return spring 39. Since the second half gear 34 is a gear with half a circle of teeth, after the second half gear 34 is disengaged from the lower rack 37, the rotary vibration ring 38 returns to its initial position under the action of the second return spring 39, thereby realizing the axial reciprocating motion of the rotary vibration ring 38, so that the spoiler rod 49 and the aeration stirring tube 46 also reciprocate along the axial direction.

[0059] like Figure 12 As shown, a driven sleeve 10 is fixedly provided on the inner wall of the middle ring structure of the rotating vibration ring 38, and a polygonal sleeve 52 is fixedly provided on the outer wall of the rotating cylinder 6. The middle ring structure of the rotating vibration ring 38 is sleeved on the outside of the polygonal sleeve 52 through the driven sleeve 10, which is beneficial to improving the stability of the rotating vibration ring 38 during axial reciprocating motion.

[0060] like Figure 8 、 12As shown, a transmission seat 50 is fixedly mounted on the pressure plate 51, and a second gear shaft 44 is rotatably mounted on the transmission seat 50. The second gear shaft 44 is arranged perpendicular to the outer rotating tube 42 and has two sets of bevel gears. A driven gear 43 is mounted on the outer rotating tube 42, and the driven gear 43 engages with the stirring gear 41. When the rotor 6 rotates, the stirring gear 41 on the rotor 6 drives the driven gear 43 to rotate, thereby rotating the outer rotating tube 42. The top of the outer rotating tube 42 is provided with bevel gears, and the top of the inner rotating tube 45 extends out of the outer rotating tube 42 and is also provided with bevel gears. The two sets of bevel gears on the second gear shaft 44 engage with the bevel gears of the outer rotating tube 42 and the bevel gears of the inner rotating tube 45, respectively. When the outer rotating tube 42 rotates, the second gear shaft 44 is driven to rotate, thereby driving the rotation of the inner rotating tube 45. The inner rotating tube 45 and the outer rotating tube 42 rotate in opposite directions, thereby achieving counter-rotating aeration of the spoiler rod 49 and the aeration stirring tube 46.

[0061] like Figure 12 As shown, since the driven gear 43 also moves up and down along the axis of the drum 6 during rotation, in order to ensure that the stirring gear 41 and the driven gear 43 are fully engaged, the height of the teeth of the stirring gear 41 is greater than or equal to the maximum distance moved by the lower rack 37 under the action of the second half gear 34. The maximum distance is the maximum distance moved by the lower rack 37 during the process from the beginning of engagement to the disengagement of the lower rack 37 and the second half gear 34. The distance the lower rack 37 moves downward is also the distance the driven gear 43 moves downward. This ensures that, in this embodiment, the height of the teeth of the stirring gear 41 is seven times that of the driven gear 43. In addition, to ensure the stable movement of the liquid vibrating frame 36, the teeth of the stirring gear 41 are only provided in the middle and lower part of the stirring gear 41. The outer wall of the middle and upper part of the stirring gear 41 is smooth. The liquid vibrating frame 36 is sleeved on the middle and upper part of the stirring gear 41 and has a clearance fit with the outer wall of the stirring gear 41.

[0062] like Figure 7 、 8 As shown, the top end of the inner rotating tube 45 is connected to the fixed ring tube 31 through the telescopic tube 48. The telescopic tube 48 and the inner rotating tube 45 are sealed and rotatably connected. The telescopic tube 48 is connected to the inside of the fixed ring tube 31. An aeration channel 47 is provided in the inner rotating tube 45. The bottom end of the aeration channel 47 is connected to the aeration stirring tube 46. The top end of the aeration channel 47 is connected to the telescopic tube 48. Figure 1 As shown, the blower 8 is connected to the interior of the fixed ring pipe 31 through a pipeline, and the blower 8 is driven by a driving mechanism. It can be understood that the blower 8 can supply air to the aeration stirring pipe 46 through the fixed ring pipe 31, the telescopic pipe 48, and the aeration channel 47 in sequence.

[0063] The method for using the aeration and sewage purification device for water environment remediation is as follows: the device is placed in water, secured with multiple cables tied to a locking ring 9, and the buoyancy of the float 1 is adjusted as needed to adjust the depth of the device. The drive device 5 and the submersible sewage pump 19 are turned on, and the drive device 5 drives the rotor 6 and the sewage lifting shaft 20 to rotate in opposite directions. Sewage enters the rotor 6 through the bottom opening, and some water in the sewage flows out of the rotor 6 through the sewage filter holes 24. Impurities in the sewage move upward from the rotor 6 under the action of the spiral sewage lifting blade 22. During this process, the remaining water in the sewage flows out through the liquid permeable holes 23 of the spiral sewage lifting blade 22. After reaching the top of the rotor 6, the impurities in the sewage are thrown into the sewage discharge chamber 26 and then into the sewage storage tank 27 through the sewage discharge pipe 28, thereby filtering the sewage.

[0064] After the driving device 5 is turned on, the drum 6 will rotate, and the bevel gear on the drum 6 will drive the first gear shaft 32 to rotate. The first half gear 33 on the first gear shaft 32 is engaged with the upper rack 35 and drives the upper rack 35 to move upward. The upper rack 35 drives the expansion ring 16 and the driven rotating ring 7 to move upward. The driven rotating ring 7 squeezes the first return spring 11. After the first half gear 33 on the first gear shaft 32 is disengaged from the upper rack 35, the driven rotating ring 7 moves upward under the action of the first return spring 11. During the reciprocating up and down motion of the driven rotary ring 7, the aeration nozzle 14 will continuously swing, and the driven rotary ring 7 will rotate together with the rotary drum 6, and the aeration nozzle 14 will rotate together with the driven rotary ring 7; at the same time, the submersible sewage pump 19 transports the water in the sewage through the lower pump liquid box 30, the pump liquid channel 21 in the sewage lifting shaft 20, the upper pump liquid box 29, the second annular cavity 18, and the first annular cavity 17 to the aeration nozzle 14, thereby realizing multi-angle and multi-range aeration of the aeration nozzle 14.

[0065] After the driving device 5 is turned on, the rotor 6 will rotate, and the bevel gear on the rotor 6 will drive the first gear shaft 32 to rotate. The second half gear 34 on the first gear shaft 32 engages with the lower rack 37 and drives the lower rack 37 to move downward. The lower rack 37 drives the liquid vibration frame 36 and the rotary vibration ring 38 to move downward. The rotary vibration ring 38 squeezes the second return spring 39. After the second half gear 34 on the first gear shaft 32 is disengaged from the lower rack 37, the rotary vibration ring 38 moves upward under the action of the second return spring 39. During the up and down reciprocating motion of the rotary vibration ring 38, the aeration stirring pipe 46 and the spoiler rod 49 will continue to move up and down, and the rotation of the rotor 6 It will drive the stirring gear 41 to rotate, and the stirring gear 41 drives the outer rotating tube 42 to rotate through the driven gear 43, so that the spoiler rod 49 rotates. The rotation of the outer rotating tube 42 drives the second gear shaft 44 to rotate, and the second gear shaft 44 drives the inner rotating tube 45 to rotate, and the inner rotating tube 45 drives the aeration stirring tube 46 to rotate around the inner rotating tube 45; at the same time, the blower 8 supplies air to the aeration stirring tube 46 through the fixed ring tube 31, the telescopic tube 48, and the aeration channel 47 in the inner rotating tube 45, realizing aeration of the aeration stirring tube 46 and the spoiler rod 49 in the process of moving up and down and rotating, effectively improving the aeration purification efficiency and the aeration purification range per unit time.
