[0002] In traditional landfill leachate purification and recycling processes, the aeration stage is time-consuming, and the oxygen supply to the leachate during aeration is not uniform enough to achieve optimal aeration within the shortest possible time. This increases the aeration time and hinders efficient and thorough leachate purification.

The adjustment module includes an adjustment tank for regulating the pH value of the leachate. The aeration assembly includes an aeration tank for holding the leachate. The blower module is located above the aeration tank and includes a blower installed above the aeration tank, a duct connected to the blower's outlet, and a stabilizing pipe connected to the other end of the duct. The power assembly is located above the aeration tank and includes a motor installed above the aeration tank and a fixed gear connected above the aeration tank and meshing with the drive gear of the motor. By configuring the power assembly and the rotation module, when the equipment starts, the rotation module can be powered by the power assembly to rotate in the aeration tank, stirring the leachate within. Subsequently, the blower's exhaust air simultaneously supplies oxygen to the leachate, increasing the aeration rate.
[0004] Based on the above search and combined with existing technology, it was found that existing leachate aeration systems require a power unit to drive the rotating module, which increases the equipment cost and energy consumption. Therefore, a high-efficiency and energy-saving leachate aeration blower system is needed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example: Reference Figures 1-4 The high-efficiency and energy-saving leachate aeration blower system shown includes an adjustment module 1, an aeration box 2 and a filtration module 3. The adjustment module 1 and the aeration box 2 should also be equipped with a pump body and pipeline (not shown in the figure) used in the prior art for transporting leachate. The aeration box 2 is equipped with a blower 4 and an aeration pipe 5. The aeration pipe 5 rotates through the upper part of the aeration box 2, and the air outlet end of the aeration pipe 5 is located in the lower part of the aeration box 2.
[0030] A pneumatic mechanism 6 is installed at the upper end of the aeration pipe 5. The upper end of the pneumatic mechanism 6 is connected to the output end of the blower 4 through a pipeline, and the lower end of the pneumatic mechanism 6 is connected to the upper end of the aeration pipe 5. The pneumatic mechanism 6 rotates with the air flow output by the blower 4, and the aeration pipe 5 rotates synchronously when the pneumatic mechanism 6 rotates.
[0031] Based on the above structure, when the airflow output by the blower 4 passes through the pneumatic mechanism 6, it drives the pneumatic mechanism 6 to rotate, thereby driving the aeration pipe 5 to rotate synchronously. The airflow is then aerated through the aeration pipe 5. Thus, the blower 4 achieves the dual function of aeration and driving. Compared with the existing technology, the motor equipment is omitted, which can reduce equipment costs and energy consumption, and achieve a highly efficient and energy-saving aeration effect.
[0032] Furthermore, the pneumatic mechanism 6 includes a fixed shroud 61, a movable flow hopper 62, and a driven vortex impeller 63. The upper end of the fixed shroud 61 is fixed and connected to the output end of the blower 4 via a pipe. The lower end of the movable flow hopper 62 is fixed and connected to the upper end of the aeration pipe 5. The movable flow hopper 62 and the fixed shroud 61 are rotatably connected via a sealed bearing 64. The windward side of the driven vortex impeller 63 faces the fixed shroud 61, and the lower end of the shaft of the driven vortex impeller 63 is fixed to the movable flow hopper 62 via a connector. The connector includes a support rod 621, which is integrally formed with the movable flow hopper 62, and the middle part of the support rod 621 is fixed to the lower end of the shaft of the driven vortex impeller 63.
[0033] By configuring the fixed hood 61, the movable flow hopper 62, and the driven vortex impeller 63, when the airflow passes through the driven vortex impeller 63, it drives the driven vortex impeller 63 to rotate. When the driven vortex impeller 63 rotates, it drives the movable flow hopper 62 to rotate synchronously. When the movable flow hopper 62 rotates, it drives the aeration pipe 5 at the lower end to rotate synchronously, thereby achieving the purpose of driving the aeration pipe 5 to rotate. The air flowing through the driven vortex impeller 63 enters the aeration pipe 5 through the movable flow hopper 62, further achieving the aeration effect.
[0034] Furthermore, the lower end of the aeration pipe 5 is integrally formed with a baffle cap 51, and the upper end of the baffle cap 51 is fixed with a plurality of aeration nozzles 52 evenly distributed in a ring along the axis of the aeration pipe 5. The airflow entering the aeration pipe 5 passes through the inner cavity of the baffle cap 51 and is sprayed out through the aeration nozzles 52 to aerate the leachate in the aeration box 2 and drive the leachate to flow, thereby promoting the uniformity of aeration.
[0035] The aeration pipe 5 is located in the upper part of the aeration box 2 and is fixed with a guide plate 8. The bottom of the guide plate 8 has an upward concave arc surface. The guide plate 8 has an overflow hole 81 that runs vertically through the guide plate 8. Multiple overflow holes 81 are opened and are evenly distributed in a ring along the central axis of the guide plate 8.
[0036] By setting the guide plate 8, the mixture of flowing leachate and air bubbles is guided, so that the mixture of leachate and air bubbles forms a circulating fluid that rolls and flows outward from the aeration box 2 below the guide plate 8, thereby prolonging the residence time of gas in leachate, further improving the fusion effect of gas and leachate, and thus improving the aeration effect.
[0037] Furthermore, the outer wall of the aeration pipe 5 is integrally formed with bubble-breaking needles 53. The length direction of the bubble-breaking needles 53 coincides with the radial direction of the aeration pipe 5. Multiple bubble-breaking needles 53 are formed and spirally distributed along the periphery of the aeration pipe 5. Multiple aeration pipes 5 are located between the lower end of the guide plate 8 and the upper end of the aeration nozzle 52.
[0038] With the setting of the bubble-breaking needle 53, the bubble-breaking needle 53 rotates along with the aeration pipe 5 during rotation, and can disturb and break up the rising mixed fluid, thereby making the bubbles further form microbubbles, greatly enhancing the gas dissolution effect of the leachate, and achieving the purpose of improving aeration efficiency and effect.
[0039] Furthermore, the output end of the fan 4 is fixed and connected to a split duct 41. The split duct 41 divides the airflow output by the fan 4 into two parts and discharges them from two outlets. One of the outlets of the split duct 41 is fixed and connected to the upper end of the fixed shroud 61 through a pipe.
[0040] Another air outlet of the diversion duct 41 is fixed and connected to an air replenishment ring cover 7 through a pipeline. The air replenishment ring cover 7 is rotatably sleeved on the upper part of the aeration pipe 5, and the air replenishment ring cover 7 is located below the movable flow hopper 62.
[0041] Multiple air supply holes 54 are provided on the upper part of the aeration pipe 5, corresponding to the circumference of the air supply ring cover 7. The multiple air supply holes 54 are distributed in a ring along the axis of the aeration pipe 5 and connect the air supply ring cover 7 and the aeration pipe 5.
[0042] By dividing the airflow output from the blower 4 into two parts, one part (flowing through the pneumatic mechanism 6) is used to drive the aeration pipe 5 to rotate, while the other part enters the aeration pipe 5 directly through the air replenishment ring cover 7. This avoids insufficient power of the airflow after passing through the pneumatic mechanism 6, ensuring sufficient air pressure during aeration, thereby improving the aeration operation stability of the leachate aeration blower system and achieving efficient and energy-saving aeration operation.
[0043] The working principle of this utility model is as follows: During daily use, the fan 4 draws in external airflow and pumps it out. When it passes through the split air duct 41, it is split into two parts of airflow. One part enters the fixed hood 61 through the pipeline. When the airflow passes through the driven vortex impeller 63, it drives the driven vortex impeller 63 to rotate. When the driven vortex impeller 63 rotates, it drives the movable flow bucket 62 to rotate synchronously. When the movable flow bucket 62 rotates, it drives the aeration pipe 5 at the lower end to rotate synchronously, thereby achieving the purpose of driving the aeration pipe 5 to rotate. The air flowing through the driven vortex impeller 63 enters the aeration pipe 5 through the movable flow bucket 62.
[0044] The other part enters directly into the aeration pipe 5 through the air supply ring 7. After the two airflows converge, they enter the inner cavity of the baffle cap 51 and are then sprayed out through the aeration nozzle 52 to aerate the leachate in the aeration box 2 and drive the leachate to flow. The guide plate 8 guides the flow of the mixture of leachate and bubbles, so that the mixture of leachate and bubbles forms a circulating fluid that rolls and flows outward from the aeration box 2 below the guide plate 8, thereby prolonging the residence time of gas in leachate and further improving the fusion effect of gas and leachate. In addition, during the rotation of the aeration pipe 5, the bubble-breaking needle 53 rotates accordingly and can disturb and break up the rising mixed fluid, thereby further forming microbubbles, greatly enhancing the gas dissolution effect of leachate, and achieving the goal of improving aeration efficiency and effect.
[0045] It should be further noted that the technical features such as the adjustment module, filter module, and fan involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.
[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
