Description

Technical Field

[0001] This utility model relates to the field of landfill leachate treatment technology, and in particular to a landfill leachate aeration treatment device. Background Technology

[0002] Landfill leachate aeration treatment device is a core piece of equipment used to treat high-concentration organic wastewater generated during the dumping and landfilling of waste. This device introduces oxygen into the landfill leachate, providing an environment necessary for the survival and reproduction of aerobic microorganisms. Relying on the metabolic action of these microorganisms, the device degrades organic pollutants, ammonia nitrogen, and other harmful substances in the leachate, reducing its pollution risk to soil, water bodies, and the atmosphere. It plays a vital role in environmental protection and ecological balance in the field of waste treatment.

[0003] However, existing landfill leachate aeration treatment devices have many shortcomings in practical applications. First, the aeration uniformity is poor. The aeration structure of traditional devices is relatively simple, and the air outlet pipes are mostly fixed, resulting in uneven oxygen distribution in the leachate. Some areas have excessively high oxygen concentrations, while other areas have insufficient oxygen supply, affecting microbial activity and pollutant degradation efficiency. Second, equipment maintenance is inconvenient. Due to the complex composition of landfill leachate, which contains a large amount of suspended solids, colloids, and impurities, these substances easily adhere to the surface of the air outlet pipes and filter components, causing blockages. The aeration components of existing devices are usually fixedly installed at the bottom of the treatment tank. During maintenance and cleaning, the entire device needs to be disassembled, which is cumbersome, time-consuming, and labor-intensive, increasing equipment maintenance costs and downtime, and reducing treatment efficiency.

[0004] Therefore, it is necessary to provide a new landfill leachate aeration treatment device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a landfill leachate aeration treatment device.

[0006] The leachate aeration treatment device provided by this utility model includes: an oxidation tank, a first pipe symmetrically installed inside the oxidation tank, a diversion pipe fixedly connected to the bottom of the first pipe, multiple sets of second pipes fixedly connected at equal intervals on one side of the diversion pipe, multiple sets of air outlet pipes rotatably connected at equal intervals to the bottom of the second pipes, a rotating component installed inside the air outlet pipe for driving the air outlet pipe to rotate, a pump body symmetrically installed on the top of the oxidation tank, the output end of the pump body fixedly connected to the first pipe, the pump body for pumping oxygen into the oxidation tank, a support frame symmetrically installed inside the oxidation tank, the support frame fixedly connected to the pump body, the first pipe, and the second pipes, a gantry frame symmetrically fixedly connected on the top of the oxidation tank, a lifting component installed inside the gantry frame for controlling the lifting and lowering of the support frame.

[0007] Preferably, the rotating assembly includes: a rotating shaft, a cross rod, and fan blades; the rotating shaft is installed in the middle of the air outlet pipe, the bottom of the rotating shaft is fixedly connected to the cross rod, the end of the cross rod is fixedly connected to the inner wall of the air outlet pipe, and fan blades are fixedly connected to the side wall of the rotating shaft at equal intervals.

[0008] Preferably, the lifting assembly includes: a threaded rod and a guide rod; one end of the gantry frame is rotatably connected to the threaded rod, and the other end of the gantry frame is fixedly connected to the guide rod; the threaded rod is threadedly connected to the support, and the guide rod is slidably connected to the support.

[0009] Preferably, the air outlet pipe is designed in an S-shape, with the middle part of the air outlet pipe rotatably connected to the bottom of the second pipe, and filter plates are fixedly connected to both ends of the air outlet pipe.

[0010] Preferably, a tapered block is fixedly connected to the end of the rotating shaft away from the cross bar.

[0011] Preferably, motors are fixedly connected inside both ends of the oxidation tank, and the output end of the motor is fixedly connected to the bottom end of the threaded rod.

[0012] Preferably, the length of the threaded rod and the guide rod is greater than the depth of the oxidation pool.

[0013] Compared with related technologies, the landfill leachate aeration treatment device provided by this utility model has the following beneficial effects:

[0014] Significantly improves aeration uniformity:

[0015] The exhaust pipe of this invention adopts an S-shaped design and works in conjunction with a rotating component. After the pump body pumps oxygen into the second pipe, the gas enters the exhaust pipe through the pipe. The fan blades rotate due to the impact of the gas, ensuring that the exhaust pipe rotates continuously and stably, thus creating a large-scale, multi-angle aeration zone within the leachate during its rotation. Furthermore, with the use of a lifting component, the exhaust pipe can be raised or lowered to any height within the oxidation tank, resulting in a more uniform distribution of oxygen inside the oxidation tank. Compared to traditional fixed exhaust pipes, this device can evenly disperse oxygen to various areas of the oxidation tank, avoiding local oxygen concentration imbalances, fully activating the activity of aerobic microorganisms, significantly improving pollutant degradation efficiency, and effectively solving the problem of poor aeration uniformity in the prior art.

[0016] Significantly improves the ease of equipment maintenance:

[0017] The lifting component in this invention plays a crucial role. A threaded rod and guide rod are installed inside the gantry frame at the top of the oxidation tank. The threaded rod is driven by a motor to rotate, enabling the support to be raised and lowered. Since the support is fixedly connected to the pump body, the first pipe, the second pipe, and other aeration components, when maintenance or cleaning of the aeration components is required, they can be lifted from the bottom of the oxidation tank to above the water surface using the lifting component. This eliminates the need to disassemble the entire device as required by existing devices, greatly simplifying the operation process and saving maintenance time and labor costs. Simultaneously, the centrifugal force generated during the rotation of the air outlet pipe automatically throws off the deposits on the filter plate surface, reducing the probability of filter plate clogging and further reducing maintenance frequency and difficulty, effectively overcoming the inconvenience of maintenance in existing devices.

[0018] Highly effective in promoting leachate treatment:

[0019] The rotating air outlet pipe also agitates the leachate; the continuous rotation and agitation break the static state of the leachate, promote liquid flow and mixing, and allow oxygen, microorganisms and pollutants to come into full contact, accelerating the oxidation reaction rate and improving the treatment efficiency and quality of landfill leachate. In addition, the connections between the various components of the device are stable, and the pump body, pipes and other components move synchronously when the support is raised and lowered, maintaining the integrity and stability of the aeration system, ensuring the safe and reliable operation of the equipment, extending the service life of the equipment, and reducing long-term operating costs.

It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 4 A landfill leachate aeration treatment device includes: an oxidation tank 1, with first pipes symmetrically installed inside the oxidation tank 1; a diversion pipe 3 fixedly connected to the bottom of the first pipes 2; multiple sets of second pipes 4 fixedly connected at equal intervals to one side of the diversion pipes 3; multiple sets of air outlet pipes 5 rotatably connected at equal intervals to the bottom of the second pipes 4; a rotating assembly installed inside the air outlet pipes 5 for driving the air outlet pipes 5 to rotate; and pump bodies 6 symmetrically installed on the top of the oxidation tank 1, with the output end of the pump body 6 fixedly connected to the first pipes 2, for supplying oxygen... The pump is fed into oxidation tank 1. Supports 7 are symmetrically installed inside oxidation tank 1. Supports 7 are fixedly connected to pump body 6, first pipe 2, and second pipe 4. A gantry frame 8 is symmetrically fixedly connected to the top of oxidation tank 1. A lifting assembly is installed inside the gantry frame 8 to control the lifting of the support 7. The exhaust pipe 5 has an S-shaped design. The middle part of the exhaust pipe 5 is rotatably connected to the bottom of the second pipe 4. Filter plates 14 are fixedly connected to both ends of the exhaust pipe 5. The fan blade 11 rotates when impacted by the gas in the second pipe 4, with the rotation direction facing the convex side of the S-shaped structure of the exhaust pipe 5.

[0028] Please see Figure 3 and Figure 4 The rotating assembly includes: a rotating shaft 9, a cross rod 10, and fan blades 11; the rotating shaft 9 is installed in the middle of the air outlet pipe 5, the bottom of the rotating shaft 9 is fixedly connected to the cross rod 10, the end of the cross rod 10 is fixedly connected to the inner wall of the air outlet pipe 5, and fan blades 11 are fixedly connected to the side wall of the rotating shaft 9 at equal intervals; a conical block 15 is fixedly connected to the end of the rotating shaft 9 away from the cross rod 10.

[0029] It should be noted that the design of the conical block 15 can concentrate the airflow in the rotation area of ​​the fan blade 11, thereby promoting the rotation of the fan blade 11.

[0030] Please see Figure 1 and Figure 2The lifting assembly includes: a threaded rod 12 and a guide rod 13; one end of the gantry frame 8 is rotatably connected to the threaded rod 12, and the other end of the gantry frame 8 is fixedly connected to the guide rod 13. The threaded rod 12 is threadedly connected to the support 7, and the guide rod 13 is slidably connected to the support 7. Motors 16 are fixedly connected to the interior of both ends of the oxidation tank 1, and the output end of the motor 16 is fixedly connected to the bottom end of the threaded rod 12. The length of the threaded rod 12 and the guide rod 13 is greater than the depth of the oxidation tank 1.

[0031] It should be noted that the lengths of the threaded rod 12 and the guide rod 13 are greater than the depth of the oxidation tank 1, so that the lifting and lowering of the support 7 can cover the oxidation tank 1.

[0032] The working principle of the landfill leachate aeration treatment device provided by this utility model is as follows:

[0033] Rotation process of exhaust pipe 5:

[0034] After the pump body 6 is started, oxygen flows continuously into the outlet pipe 5 through the first pipe 2, the diversion pipe 3, and the second pipe 4. During this process, the rotating component inside the outlet pipe 5 plays an important role. When the gas flows through the outlet pipe 5, it will generate an impact force on the fan blade 11. The fan blade 11 starts to rotate under the impact of the gas. The fan blade 11 is connected to the cross rod 10 through the rotating shaft 9. The end of the cross rod 10 is fixed to the inner wall of the outlet pipe 5. Therefore, the rotation of the fan blade 11 can drive the rotating shaft 9 and the outlet pipe 5 to rotate together.

[0035] The rotation of the exhaust pipe 5 not only achieves uniform oxygen dispersion but also stirs the leachate. During the rotation, the exhaust pipe 5 continuously agitates the surrounding leachate, breaking the static state of the liquid, promoting the flow and mixing of the leachate, and allowing oxygen to fully contact the pollutants in the leachate, accelerating the oxidation reaction and thus effectively improving the treatment effect of landfill leachate. At the same time, the centrifugal force generated by the rotation of the exhaust pipe 5 can throw off the deposits attached to the surface of the filter plates 14 at both ends, reducing filter plate blockage and ensuring the smooth flow of oxygen.

[0036] Lifting and lowering process of bracket 7:

[0037] The motors 16, which are fixedly connected to both ends of the oxidation tank 1, provide the power source for the lifting and lowering of the support 7. When the support 7 needs to be lifted or lowered, the motors 16 start, and the output end of the motors 16 drives the threaded rod 12 to rotate. Since the threaded rod 12 is threadedly connected to the support 7, the support 7 will move axially along the threaded rod 12 when the threaded rod 12 rotates, according to the principle of thread transmission. At the same time, the guide rod 13, which is fixedly connected to the other end of the gantry 8, plays a key role. It is slidably connected to the support 7 and provides guidance for the movement of the support 7, ensuring that the support 7 will not deviate or rotate during the lifting and lowering process, and always maintains a stable vertical lifting and lowering state.

[0038] The lengths of the threaded rod 12 and the guide rod 13 are greater than the depth of the oxidation tank 1, which allows the support 7 to be adjusted up and down over a wide range within the oxidation tank 1. When the support 7 rises, it can lift components such as the first pipe 2, the second pipe 4, and the air outlet pipe 5 located near the bottom of the oxidation tank 1, facilitating maintenance operations such as inspection, cleaning, or replacement of these components. When the support 7 descends, it can lower the aeration components to a suitable position, allowing the air outlet pipe 5 to penetrate deep into the leachate, ensuring that oxygen can be efficiently dispersed to different depths and areas of the leachate, meeting the aeration requirements of different treatment stages, and improving the treatment efficiency and quality of landfill leachate.

[0039] During the entire process of raising and lowering the support 7, the support 7 is also fixedly connected to the pump body 6, the first pipe 2, and the second pipe 4. This ensures that when the support 7 is raised and lowered, the pump body 6, pipes, and other components can move synchronously, maintaining the integrity and stability of the aeration system and avoiding problems such as loose connections or pipe damage caused by relative displacement between components. This ensures the safe, reliable, and stable operation of the landfill leachate aeration treatment device.
