Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an energy-saving and environmentally friendly wastewater purification and aeration treatment device. Background Technology

[0002] In wastewater treatment processes, aeration equipment is one of the key pieces of equipment, playing a crucial role, especially in the treatment of municipal sewage and industrial wastewater. The main function of aeration equipment is to transfer oxygen from the air into the liquid within the aeration tank using specific technical means, supplying the oxygen needed for the metabolism of aerobic microorganisms, while simultaneously achieving thorough and uniform mixing of the water within the tank, thus achieving the purpose of biological treatment.

[0003] Existing aeration devices are typically located at the bottom of the aeration tank. This design allows dirt and impurities to easily accumulate around the aeration holes, clogging them and affecting the normal operation of the aeration equipment. Clogged aeration holes not only reduce aeration efficiency but also increase energy consumption and maintenance costs. Parameters such as the power efficiency, oxygenation capacity, and oxygen transfer rate of the aeration equipment decrease significantly when the aeration holes are clogged, requiring more energy to maintain the necessary aeration effect. Furthermore, during aeration, a large amount of foam is generated on the surface of the aeration tank. This foam, composed of microbubbles, suspended solids in the wastewater, and microbial metabolic products, floats on the surface, forming a barrier layer that severely hinders the contact between the liquid and air, thus affecting dissolved oxygen levels. The presence of foam not only reduces aeration efficiency but also adversely affects subsequent wastewater treatment steps, such as impacting sedimentation and effluent quality.

[0004] An invention patent with application number "CN202210947780.5" discloses an aerator for industrial wastewater treatment, including a fixed outer shell, a rotating head driven by a rotating head drive assembly and a plurality of extendable and retractable telescopic components disposed on the rotating head; each telescopic component is provided with a plurality of oxygen injection ports; the lower end of the fixed outer shell is provided with an air inlet, which is connected to the plurality of oxygen injection ports; one end of each telescopic component is hinged to the rotating head and driven by a drive disc to switch between extension and retraction, during which a moving block moves and resets, and drives the telescopic component to retract under the cooperation of a reset component. This application adjusts the horizontal height of the aeration device by extending and retracting the telescopic rod, which improves the aeration efficiency to some extent, but it does not address the problems of vibration aeration hole blockage and foaming in the aeration tank, resulting in high maintenance costs and affecting sedimentation and effluent quality during use. Summary of the Invention

[0033] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see the appendix Figure 1-9 This embodiment discloses an energy-saving and environmentally friendly wastewater purification aeration treatment device, comprising a base 1, an aeration pipe 2 fixedly connected to the base 1, an aeration cylinder 3 slidably connected to the aeration pipe 2, an aeration hole 4 on the side of the aeration cylinder 3, an anti-clogging sleeve 5 on the outside of the aeration hole 4, the anti-clogging sleeve 5 being fixedly connected to the base 1, an air outlet 6 at the upper end of the aeration cylinder 3, a hollow telescopic frame 7 connected to the outer end of the air outlet 6, one end of the telescopic frame 7 being fixedly connected to the aeration cylinder 3, and the other end of the telescopic frame 7 being rotatably connected to a defoaming mechanism 8, an air nozzle 903 driving mechanism fixedly connected to the upper end of the defoaming mechanism 8, the interior of the air nozzle 903 driving mechanism being connected to the air outlet 6.

[0036] Aeration pipe 2 is located in the middle of base 1, and rises vertically. An air pump connected to aeration pipe 2 is installed inside base 1, providing a continuous supply of gas to aeration pipe 2 through the air pump's operating position. Aeration cylinder 3 is fitted over aeration pipe 2, and anti-clogging sleeve 5 is fitted over aeration cylinder 3. Aeration cylinder 3 and anti-clogging sleeve 5 are tightly connected. Aeration cylinder 3 is sequentially equipped with a telescopic frame 7, a defoaming mechanism 8, and an air nozzle 903 drive mechanism. The telescopic frame 7 is used to adjust the height of the defoaming mechanism 8 and the air nozzle 903 drive mechanism, ensuring that they are positioned within the aeration tank liquid during use. Above the surface, the desquamation mechanism 8 is driven by the air nozzle 903. The air nozzle 903 drives the air mechanism by spraying gas out through the air outlet 6. The air pressure difference drives the gas drive mechanism to rotate. At the same time, the airflow from the air nozzle 903 also acts on the liquid surface in the aeration tank, blowing away some of the foam on the liquid surface to prevent the foam from affecting the dissolved oxygen efficiency of the aeration tank. The rotation of the desquamation mechanism 8 driven by the airflow not only simplifies the equipment structure but also improves energy utilization. The air required for desquamation is directly supplied to the aeration process without the need for an additional power source.

[0037] The defoaming mechanism 8 includes a connecting block 801, which is rotatably connected to the telescopic frame 7. A connecting pipe 802 is fixedly connected to the upper end of the connecting block 801, and a float plate 803 is fixedly connected to the connecting pipe 802. An annular airbag 804 is fixedly connected below the float plate 803. A sliding sleeve 805 is slidably connected to the upper side of the float plate 803, and a traction rope 806 is fixedly connected to the sliding sleeve 805. A counterweight ball 807 is fixedly connected to the end of the traction rope 806.

[0038] Connecting block 801 is the connection point between the defoaming mechanism 8 and the telescopic frame 7. The rotatable connection between connecting block 801 and telescopic frame 7 is similar to the principle of a rotary joint, allowing the defoaming mechanism 8 to rotate on the telescopic frame 7 without affecting the gas in the vent 6 being transported through the hollow telescopic frame 7 to the connecting pipe 802. The connecting pipe 802 is fixedly connected to the upper end of connecting block 801. The connecting pipe 802 serves two purposes: supporting the float plate 803 and transmitting gas to the air nozzle 903 drive assembly. The float plate 803 has a columnar structure, with multiple air bladders 804 below it. The air bladders 804 have a ring-shaped structure and are installed at the bottom of the float plate 803. When the air bladders 804 are inflated, the buoyancy of the float plate 803 increases. The buoyancy of the float plate 803 overcomes the weight of the defoaming mechanism 8 and the air nozzle 903 drive mechanism, causing the telescopic frame 7 to adjust its length, thereby ensuring buoyancy. After the float plate 803 contacts the liquid surface, it will suspend above the liquid surface. The counterweight ball 807 and the traction rope 806 are located above the float plate 803. The counterweight ball 807 is a solid sphere with a high density. The traction rope 806 is located between the solid sphere and the sliding sleeve 805. The traction rope 806 has good toughness. When the float plate 803 rotates, due to the large weight of the solid sphere, under the action of centrifugal force, the solid sphere drives the traction rope 806 to move outward relative to the float plate 803. At the same time, the solid sphere will continue to rotate with the float plate 803. By pulling the traction rope 806 outward, the area of ​​rotation of the solid sphere increases. With the rotation of the solid sphere and the traction rope 806, the foam in the aeration tank will be cut and broken. The broken foam will be blown away by the airflow of the air nozzle 903 driven by the air nozzle 903, thereby completing the foam removal work in the aeration tank, avoiding the foam from affecting the dissolved oxygen efficiency of the wastewater in the aeration tank, and improving the efficiency of wastewater treatment.

[0039] The air nozzle 903 driving mechanism includes a four-way connector 901. The bottom of the four-way connector 901 is connected to the connecting pipe 802. Three obliquely cut bends 902 with equal angles are fixedly connected to the upper end of the four-way connector 901. The air nozzle 903 is fixedly connected to the end of the obliquely cut bends 902.

[0040] The bottom connection hole of the four-way connector 901 is fixedly connected to the connecting pipe 802. The three connection holes on the upper side of the four-way connector 901 are used for diversion. Three oblique bends 902 are connected to the upper side of the four-way connector 901. The oblique bends 902 are distributed at equal angles at the upper end of the four-way connector 901 to ensure that the gas can be evenly distributed and generate a balanced driving force. The gas passing through the outlet 6 enters the oblique bends 902 through the four-way connector 901 and is ejected from the nozzle 903. Due to the special design of the oblique bends 902, the gas will generate a torque perpendicular to the injection direction. This torque will act on the four-way connector 901, causing it to rotate. Since the three oblique bends 902 are distributed at equal angles, the torques they generate will balance each other, thereby ensuring that the four-way connector 901 can rotate smoothly and continuously. The oblique bends 902 are connected to the nozzle 903. The nozzle 903 is slightly bent downwards, and the gas is sprayed onto the wastewater surface or a specific area through the nozzle 903.

[0041] Three sets of traction ropes 806 are connected to the sliding sleeve 805. To ensure proper storage of the traction ropes 806 and the counterweight, and to avoid affecting their operation, a slot is provided in the middle of the sliding sleeve 805. The sliding sleeve 805 is fitted onto the connecting pipe 802. The first spring 808 exerts an upward force on the sliding sleeve 805. In the initial state, the sliding sleeve 805 moves the traction ropes 806 away from the float 803. When the float 803 rotates, the centrifugal force of the counterweight ball 807, through the traction ropes 806, causes the sliding sleeve 805 to compress the first spring 806 downwards. 08. When the sliding sleeve 805 moves downward, the length of the traction rope 806 extending outward increases, thus not affecting the operation of the traction rope 806 and the counterweight ball 807. The reversing wheel 809 is a fixed pulley, located above the traction rope 806. The reversing wheel 809 reduces the friction coefficient of the traction rope 806, facilitating the back-and-forth movement of the traction rope 806. The guide block 810 guides the traction rope 806, preventing the three sets of traction ropes 806 from tangling with each other, and also neatly placing the three sets of traction ropes 806 above the float 803.

[0042] The rotary joint is rotatably installed inside the aeration holes 4. Aeration holes 4 surround the side of the aeration cylinder 3. The interior of the aeration cylinder 3 is a closed space. When the aeration pipe 2 exhausts gas, the gas inside the aeration cylinder 3 increases, and the gas inside the aeration cylinder 3 is discharged outward through the aeration holes 4. The rotary joint has a cavity communicating with the aeration holes 4 inside. A pressure-boosting hole 12 is provided on the outside of the rotary joint. The pressure-boosting hole 12 is installed on the protective plate 11, which has an arc-shaped structure. The edge of the protective plate 11 is tangent to the cylindrical surface of the rotary joint. The pressure-boosting hole 12 is located on the side of the rotary joint. To prevent the rotary joint from interfering with the mutual interaction between the anti-clogging sleeve 5 and the aeration cylinder 3, the rotary joint... The length of the rotary joint is less than the length of the aeration hole 4, and the rotary joint is completely placed inside the aeration hole 4. At the same time, in order to prevent the pressure-boosting hole 12 of the rotary joint from acting on the side wall of the aeration cylinder 3 when spraying air, a wedge-shaped surface is written on the side of the guard plate 11, and the pressure-boosting hole 12 is located at the wedge-shaped surface, so that the airflow sprayed from the pressure-boosting hole 12 is sprayed outward at a certain angle, avoiding the airflow from colliding with the outer wall of the aeration cylinder 3, and ensuring the impact effect of the airflow on the liquid. Under the action of the pressure-boosting hole 12 and the guard plate 11, the rotary joint rotates while emitting air during aeration, increasing the effective range of the pressure-boosting hole 12, ensuring the aeration effect of the device at the bottom of the aeration tank, and avoiding the occurrence of aeration dead zones.

[0043] The second slide rod 703 inside the telescopic frame 7 is fitted onto the first slide rod 702. The outer side of the first slide rod 702 has a columnar structure, and the second slide rod 703 has a through groove that mates with the first slide rod 702. The length of the telescopic frame 7 is adjusted by the relative sliding of the first slide rod 702 and the second slide rod 703. Furthermore, to enable the telescopic frame 7 to automatically adjust its length according to the depth of the aeration tank during use, a first pad 705 is installed on the first support rod 701 and the first slider. Similarly, a second pad 706 is installed between the second slider and the second support rod 704. The first pad 705 and the second pad 706 are connected by a support rod 707. There are multiple support rods 707, and the multiple support rods 707 surround the first support rod 702. Around the first pad 705 and the second pad 706, the second spring 709 exerts an upward elastic force on the baffle 710, thus ensuring that in the initial state, the first pad 705 and the second pad 706 are in a relatively close position. At this time, the telescopic frame 7 is in a retracted state, and the overall volume of the device is relatively small, making it easy to move and transport. After the device is installed in the aeration tank, under the action of the float 803, the second support rod 704 receives an upward traction force. The second support rod 704 has a tendency to drive the second pad 706 to move upward. The second pad 706 compresses the second spring 709 upward, thereby causing the second slide rod 703 to move upward relative to the first slide rod 702. The telescopic frame 7 automatically adjusts according to the depth of the liquid surface in the aeration tank.

[0044] To further enhance the sealing between the aeration cylinder 3 and the aeration pipe 2, a sealing plate 14 is installed below the aeration cylinder 3. The sealing plate 14 is slidably connected to the anti-clogging sleeve 5 via a guide rod 13. The diameter of the sealing plate 14 is larger than the diameter of the aeration cylinder 3. The sealing plate 14 slides vertically within the guide rod 13, preventing the aeration cylinder 3 from detaching upwards from the anti-clogging sleeve 5 under the limiting effect of the guide rod 13. The sealing plate 14 has a slot in the middle that mates with the aeration pipe 2. The length of the aeration pipe 2 is greater than the height of the guide rod 13, preventing the aeration pipe 2 from shifting upwards after the aeration cylinder 3 moves upwards. To further ensure that the aeration cylinder 3 falls back into the anti-clogging sleeve 5 when not in operation, a third spring 15 is added to the guide rod 13. This ensures the smooth fall of the aeration cylinder 3. At the same time, the elastic coefficient of the third spring 15 is greater than that of the second spring 709. When the second pad in the telescopic frame 7 compresses and pulls the second spring 709, this pulling force is less than the elastic force of the third spring 15. The third spring 15 is compressed by the air pressure of the aeration pipe 2. When the aeration pipe 2 is closed, it falls back smoothly under the action of the third spring 15 and its own weight.

[0045] Example 2

[0046] The structure is the same as that of the above embodiments, such as Figure 10 As shown, the specific difference in this embodiment is that: both the telescopic frame 7 and the connecting block 801 are provided with fixing holes 17, and fixing bolts are installed in the fixing holes 17; the aeration cylinder 3 is rotatably connected to the anti-clogging sleeve 5; the sealing plate 14 is rotatably installed below the aeration cylinder 3; a stirring mechanism is installed on the aeration cylinder 3 and the telescopic frame 7; the stirring mechanism includes a booster turbine 18; the booster turbine 18 is fixedly connected to the aeration cylinder 3; the booster turbine 18 is provided with a slot for the telescopic frame 7 to pass through; a stirring rod 19 is provided above the booster turbine 18; and the stirring rod 19 is fixedly connected to the telescopic frame 7.

[0047] A fixing component is installed between the telescopic frame 7 and the defoaming mechanism 8. The fixing component consists of fixing holes 17 and fixing bolts. The fixing holes 17 and fixing bolts fix the connecting block 801 to the telescopic frame 7, restricting their relative rotation. This allows the air nozzle 903 drive mechanism to drive the defoaming mechanism 8 to rotate, which in turn drives the telescopic frame 7 and the aeration cylinder 3 to rotate synchronously. The booster turbine 18 on the aeration cylinder 3 and the stirring rod 19 on the telescopic frame 7 are both located inside the aeration tank. The rotation of the booster turbine 18 and the stirring rod 19 will stir the liquid in the aeration tank, improve the fluidity of the liquid in the aeration tank, and increase the aeration effect of the liquid in the aeration tank.

[0048] Furthermore, to increase the effective range of the device within the aeration tank and avoid aeration dead zones, a drive guide rail 20 is installed at the bottom of the base 1. The length of the drive guide rail 20 is the same as that of the aeration tank. Both ends of the drive guide rail 20 are equipped with mounting seats 21, which are fixed to the bottom of the aeration tank by expansion screws. A horizontal actuator is mounted on the drive guide rail 20, and the base 1 can reciprocate on the drive guide rail 20. Through the action of the drive guide rail 20, the device can move laterally within the aeration tank, avoiding aeration dead zones during the aeration process and improving the wastewater treatment effect.

[0049] The overall workflow of this invention is as follows: In the initial state, the aeration cylinder 3 is located inside the anti-clogging sleeve 5, while the telescopic frame 7 is in its shortest retracted state. The traction rope 806 and counterweight ball 807 within the desquamation mechanism 8 are located on the float 803. At this time, the device is in its minimum volume state. During use, the base 1 is installed at the bottom of the aeration tank. After installation, the air bladder 804 at the lower end of the float 803 is inflated according to the state of the float 803. After the air bladder 804 is inflated to a certain extent, it drives the float 803 upwards. The upward movement of the float 803... The second support rod 704 moves upward, and under the upward buoyancy, it compresses the second spring 709, thus lengthening the telescopic frame 7. When the float 803 is above the liquid surface, the telescopic frame 7 remains stable. During aeration, the aeration pipe 2 and the bellows 16 release air outward. The aeration pipe 2 is directly opposite the top wall of the aeration cylinder 3. The gas inside the aeration pipe 2 exerts an upward force on the aeration cylinder 3. Under this force, the aeration cylinder 3 compresses the third spring 15 upward, causing the aeration cylinder 3 to move upward relative to the anti-clogging sleeve 5. The upward movement of the aeration cylinder 3 exposes the position of the burst hole. The gas inside aerator 3 diffuses outward through aeration holes 4 and rotating head 10. Rotating head 10 rotates while aerating, aided by pressure holes 12 and protective plates 11. As aerator 3 moves upward, it drives the upper telescopic frame 7, defoaming mechanism 8, and air nozzle 903 to move upward synchronously. At this time, the bottom of float plate 803 leaves the water surface. After the buoyancy at the bottom of float plate 803 decreases, the second spring 709 drives the second pad 706 downward, automatically adjusting the length of telescopic frame 7. The corrugated pipe 16 connects to the outlet 6 and the telescopic frame 7, allowing the ejected gas to enter the... Inside the connecting pipe 802, the gas is divided into three parts by the four-way connector 901. The three parts of gas are sprayed outward through the air nozzle 903. The airflow provides torsional force to the four-way connector 901 and the connecting pipe 802 through the oblique bend pipe 902 and the nozzle. The rotation of the connecting pipe 802 drives the float plate 803 to rotate. The rotation of the float plate 803 drives the counterweight ball 807 and the traction rope 806 to rotate synchronously. When the counterweight ball 807 rotates, it is pulled outward by the centrifugal force, thereby increasing the effective range of the counterweight ball 807 and breaking and cutting the foam on the surface of the aeration tank.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
