Abstract
Description
Technical Field
[0001] This utility model relates to the field of landfill treatment technology, specifically to a landfill odor decomposition device. Background Technology
[0002] Odor decomposition in landfills is a key area of environmental governance. The core issue lies in treating the odor components generated during the decomposition of organic waste in landfills. These mainly include ammonia, hydrogen sulfide, methane, dimethyl sulfide, and dimethyl disulfide, among others. These gases are highly irritating and pose a serious threat to the environment and human health. To address this problem, there are two main treatment methods: First, utilizing the decomposition properties of biological enzymes, which can directly alter the molecular structure of harmful gases, completely decomposing odorous organic matter into carbon dioxide and water. This process does not cause secondary pollution and is harmless to humans and animals. Second, using specially cultivated microorganisms. These microorganisms have the ability to engulf and decompose odor molecules, making the process both environmentally friendly and harmless. It requires small quantities, is low-cost, and easy to operate, ultimately achieving effective odor decomposition.
[0003] The patent with publication number CN211756144U discloses a spray deodorization device for landfills, including a traveling trolley, a filter device mounted on the traveling trolley, a water tank, and spray nozzles; the filter device is connected to the water tank via a connecting pipe; the water tank has a feeding port for adding deodorizing agent; the traveling trolley is equipped with a lifting platform, and a support rod is mounted on the lifting platform, with a rotating disk connected to the top of the support rod via a bearing; the spray nozzles are mounted on the rotating disk; a water pump is installed inside the water tank, and the water pump is connected to the spray nozzles via a spray pipe.
[0004] However, the odor treatment devices described above still have the following problems: the efficacy of some deodorizing agents decreases significantly after prolonged mixing with water. Therefore, during deodorization operations, it is usually necessary to temporarily mix the agents to ensure effectiveness. However, this means that after each spraying of the mixed solution, the operator must remix the agents before continuing deodorization. This process is not only cumbersome but also greatly reduces the efficiency of deodorization operations. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Please see Figures 1 to 5 A landfill odor decomposition device includes a mobile platform 1, on which two mixing tanks 2 are fixedly connected. Each mixing tank 2 is equipped with a stirring rod 3. The tops of the two stirring rods 3 penetrate through the two mixing tanks 2 and are connected to a drive mechanism. The bottom of the two mixing tanks 2 is connected to a liquid outlet assembly on the same side. The other end of the liquid outlet assembly is connected to a filter 4. The other end of the filter 4 is fixedly connected to and connected to a booster pump 5. The liquid outlet of the booster pump 5 is connected to an atomizing nozzle 6 through a hose. The atomizing nozzle 6 is connected to a lifting assembly, which is connected to the mobile platform 1. Each of the two mixing tanks 2 is equipped with a water inlet and a chemical dosing inlet at the top.
[0021] like Figures 1 to 5As shown, the odor decomposition device for landfills in this utility model is structurally similar to existing landfill odor decomposition devices, such as the spray deodorization device for landfills disclosed in patent publication number CN211756144U. The main improvement of this utility model lies in the fact that by setting two mixing boxes 2, the deodorizing agent is continuously mixed, thereby improving the efficiency of the deodorization operation. Figures 1 to 5 As shown, the landfill odor decomposition device of this utility model, when in use, uses two mixing tanks 2 to circulate and mix the deodorizing agent. A booster pump 5, through a filter 4 and a liquid outlet assembly, sequentially introduces the mixed liquid from the two mixing tanks 2 into atomizing nozzles 6 via hoses, and sprays it onto the landfill for odor decomposition and deodorization. While the liquid in one mixing tank 2 is being sprayed outwards, the other mixing tank 2 continues to mix and stir the liquid. Before the liquid in one mixing tank 2 is completely sprayed, the liquid in the other mixing tank 2 has already been mixed and is then continuously used in the spraying operation, ensuring uninterrupted deodorization and improving the efficiency of landfill odor decomposition. The filter 4 filters the liquid, preventing particulate matter in the liquid from clogging the atomizing nozzles 6.
[0022] like Figures 1 to 4 As shown, the drive mechanism includes a drive motor 7, a drive pulley 8, a transmission belt 9, and two transmission wheels 10. A mounting plate 11 is fixedly connected between the two mixing tanks 2. The drive motor 7 is fixedly connected to the mounting plate 11. The drive pulley 8 is fixedly connected to the output shaft of the drive motor 7. The two transmission wheels 10 are respectively fixedly connected to one end of each of the two stirring rods 3 that pass through the mixing tank 2. The transmission belt 9 is triangular and simultaneously sleeves the drive pulley 8 and the two transmission wheels 10. When the drive motor 7 starts, the rotation of the drive pulley 8 causes the transmission belt 9 to simultaneously drive the two transmission wheels 10 to rotate, which in turn synchronously drives the stirring rods 3 inside the two mixing tanks 2 to rotate and stir, improving the stirring efficiency and maintaining the stirring operation inside the mixing tanks 2 at all times. This ensures that the medicine solution inside the mixing tanks 2 is mixed evenly during use, improving the effectiveness of the medicine solution.
[0023] like Figures 1 to 4As shown, the liquid dispensing assembly includes a suction pipe 12 and two dispensing pipes 13. One end of each dispensing pipe 13 is fixedly connected to and communicates with the bottom of the two mixing tanks 2, and the other end of each dispensing pipe 13 is fixedly connected to and communicates with the suction pipe 12. The end of the suction pipe 12 away from the two dispensing pipes 13 is fixedly connected to and communicates with the filter 4. Solenoid valves 14 are installed on both dispensing pipes 13. The liquid medicine in the two mixing tanks 2 is introduced into the suction pipe 12 and the filter 4 through the dispensing pipes 13, and then pumped upwards into the atomizing nozzle 6 by the booster pump 5 to form a spray of liquid medicine. At the same time, one of the two solenoid valves 14 is open and the other is closed, keeping the mixing tank 2 in one place connected to the booster pump 5 while the other closed mixing tank 2 is used for mixing and stirring of the liquid medicine.
[0024] like Figures 1 to 5 As shown, the lifting assembly includes a fixed pipe 15 and a lifting pipe 16. The fixed pipe 15 is fixedly connected to the upper surface of the mobile platform 1, and the lifting pipe 16 is slidably connected to the inner wall of the fixed pipe 15. The top of the lifting pipe 16 is fixedly connected to the atomizing nozzle 6. A drive assembly is connected to the inner wall of the lifting pipe 16, and the drive assembly is connected to the mobile platform 1. The lifting pipe 16 rises or falls within the fixed pipe 15 via the drive assembly, thereby driving the atomizing nozzle 6 at the top to rise or fall. The spray height of the atomizing nozzle 6 can be adjusted according to the actual situation, so as to better allow the sprayed liquid to come into contact with and decompose the odor of the landfill.
[0025] like Figures 1 to 5 As shown, the drive assembly includes a lifting motor 17, a connecting rod 18, an external threaded block 19, and two limiting blocks 20. The inner wall of the fixed tube 15 has two limiting grooves 101. The two limiting blocks 20 are slidably connected to the two limiting grooves 101 respectively. Both limiting blocks 20 are fixedly connected to the side wall of the lifting tube 16 away from the atomizing nozzle 6. The lifting tube 16 is an internally threaded tube. The external threaded block 19 is threadedly connected to the lifting tube 16. The lifting motor 17 is fixedly connected to the bottom of the moving platform 1. The output shaft of the lifting motor 17 passes through the moving platform 1 and is fixedly connected to the connecting rod 18. The connecting rod 18 is located inside the lifting tube 16. The other end of the connecting rod 18 is fixedly connected to the external threaded block 19. Start the lifting motor 17, which drives the connecting rod 18 and the external threaded block 19 to rotate inside the lifting tube 16. Then, through the threaded connection, the lifting tube 16 is driven to rise and fall inside the fixed tube 15. At the same time, the bottom of the lifting tube 16 slides between the limit block 20 and the limit slide groove 101, which can ensure that the lifting tube 16 only moves up and down inside the fixed tube 15.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
