Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 As shown;

[0027] A device for degrading organic matter in ammonia water using a Fenton method comprises a degradation barrel 1.

[0028] In this embodiment: although the design can automatically adjust the liquid storage space according to the water level in the treatment barrel to achieve quantitative addition of the reagent, the above-mentioned device usually only has a single stirring mode, which may not be able to fully mix the materials in the reaction liquid, resulting in insufficient contact between the Fenton reagent and the organic matter in the ammonia water, thereby affecting the progress of the oxidative degradation reaction. The lack of a design with an efficient stirring mechanism may lead to dead corners and blind spots during the stirring process, making it impossible to effectively degrade the organic matter in these areas, reducing the overall treatment effect. In order to solve this technical problem, a stirring component 2 is added on this basis.

[0029] More specifically:

[0030] like Figures 1 to 5 As shown:

[0031] In combination with the above content: the stirring assembly 2 includes a motor 21, a first bevel gear 22 and a first connecting rod 23. The motor 21 is installed on the upper surface of the end of the degradation barrel 1. The outer side of the main shaft of the motor 21 is fixedly connected to the first bevel gear 22. The outer side of one side end of the first bevel gear 22 is fixedly connected to the first connecting rod 23. The inner side of the top of the degradation barrel 1 is fixedly connected to the mounting bracket 24. The inner side of one end of the mounting bracket 24 is rotatably connected to the second bevel gear 25. The inner side of the end of the mounting bracket 24 is rotatably connected to the second connecting rod 26. The outer side of the end of the second connecting rod 26 is fixedly connected to the third bevel gear 27. The first bevel gear 22 and the third bevel gear 27 are both connected to the second bevel gear The gear 25 is meshed and connected, the outer side of the end of the second connecting rod 26 is fixedly connected to the rotating frame 28, the inner side of the end of the rotating frame 28 is rotatably connected to a plurality of stirring blades 211, the inner side of the end of the stirring blade 211 is fixedly connected to the fourth bevel gear 210, and the rod sleeve 29 is rotatably connected between the two fourth bevel gears 210. The outer side of the first connecting rod 23 is rotatably connected to the inner side of the second connecting rod 26 and the plurality of rod sleeves 29, and the outer side of each fifth bevel gear 212 is meshed and connected to the outer sides of the two fourth bevel gears 210. Multiple groups of fourth bevel gears 210 and stirring blades 211 are provided on the outer sides of the first connecting rod 23 and the second connecting rod 26.

[0032] In this embodiment: when the user uses the device, the device can be moved to a specified position. At this time, the user can put the material to be processed and degraded into the interior of the degradation barrel 1. At this time, the user can start the motor 21. The motor 21 drives the first bevel gear 22 on the outer side of its main shaft to rotate. During the rotation of the first bevel gear 22, the second bevel gear 25 meshing with the first bevel gear 22 is driven to rotate. During the rotation of the second bevel gear 25, the third bevel gear 27 is driven to rotate. During the rotation of the first bevel gear 22, the first connecting rod 23 is driven to rotate. During the rotation of the third bevel gear 27, the second connecting rod 26 is driven to rotate, thereby causing the first connecting rod 23 to rotate inside the second connecting rod 26. When the first connecting rod 23 rotates, it drives the third bevel gear 27 to rotate. The plurality of fifth bevel gears 212 on the outer side of the end of a connecting rod 23 rotates. During the rotation of the fifth bevel gear 212, the plurality of fourth bevel gears 210 on the inner side of the rotating frame 28 are driven to rotate at the same time, thereby driving the stirring blade 211 on the outer side of the end of the fourth bevel gear 210 to rotate. When the second connecting rod 26 rotates, the stirring blade 211 is driven to perform a circular motion through the rotating frame 28. The coaxial stirring assembly 2 makes the stirring more sufficient and the mixing between the materials more uniform by the superposition of the self-rotation and circular motion of the stirring blade 211. This dual rotation method helps to break the formation of the fluid layer and the solid layer, promotes mass transfer and reaction between different components, thereby improving the rate and efficiency of the Fenton reaction. Due to the more uniform stirring, the Fenton reagent Fe2 +H2O2 can contact and react more fully with the organic matter in the ammonia water, avoiding local over-reaction or under-reaction, making the degradation of organic matter in the entire reaction system more uniform. Compared with the traditional stirring method, the coaxial stirring component 2 has a more compact structure and occupies a smaller area. This design is particularly suitable for wastewater treatment sites with limited space, such as chemical plants, sewage treatment plants, etc. The coaxial stirring component 2 optimizes the stirring method to make the stirring process more efficient and can achieve a higher stirring effect with lower energy consumption, which helps to reduce the operating cost of wastewater treatment and improve economic benefits. The design of the coaxial stirring mechanism can reduce the vibration and noise generated during the stirring process, improve the stability and service life of the equipment, and at the same time, the stable stirring environment also helps to ensure the stable progress of the Fenton reaction.

[0033] Going further:

[0034] In an optional embodiment, a plurality of blade holes 213 are formed on the inner side of the end of the stirring blade 211 .

[0035] In this embodiment: opening blade holes 213 on the stirring blades 211 in the device for degrading organic matter in ammonia water by the Fenton method can bring significant benefits in many aspects. First, the design of the blade holes 213 helps to increase gas exchange and solubility during the stirring process, so that the dissolved oxygen content in the reaction system is improved, thereby enhancing the oxidation capacity of the Fenton reaction. Secondly, the blade holes 213 can reduce the weight of the stirring blades 211, reduce energy consumption during the stirring process, and at the same time improve the stirring efficiency, making the stirring more uniform and efficient. In addition, the blade holes 213 can also promote the flow and turbulence of the reaction liquid during the stirring process, enhance the mixing and contact opportunities of the reactants, and further accelerate the oxidation degradation process of the organic matter. These benefits combined have significantly improved the processing efficiency, energy consumption control, and organic matter degradation effect of the device for degrading organic matter in ammonia water by the Fenton method. Therefore, opening the blade holes 213 on the stirring blades 211 is a scientific and practical design optimization strategy.

[0036] Going further:

[0037] In an optional embodiment, a plurality of universal wheels 214 are installed on the outer side of the bottom end of the degradation barrel 1 .

[0038] In this embodiment: after the universal wheels 214 are installed, the entire device can be easily moved within the factory or laboratory and is no longer restricted to a fixed position. This flexibility allows the device to be quickly transferred to different treatment areas or laboratory environments according to actual needs, greatly improving the convenience of use. When treating different batches of wastewater or adjusting process flow, the device may need to be moved frequently. The universal wheels 214 enable the device to flexibly turn and move in uneven or limited spaces, reducing the movement difficulties caused by space limitations or ground conditions. When it is necessary to start treating wastewater, the operator can quickly move the device to the designated location and put it into use without the need for complicated installation and debugging processes. This rapid deployment capability is very useful. It helps to shorten the processing cycle and improve overall work efficiency. During daily maintenance and care, operators can easily move the device to the designated maintenance area for cleaning, inspection and replacement of parts. This not only reduces maintenance time and cost, but also increases the service life of the equipment. Traditional fixed devices need to rely on manpower or machinery for transportation and movement, which is time-consuming and labor-intensive. After installing the universal wheel 214, the operator only needs to gently push or pull the device to move it, which greatly reduces labor costs. The use of the universal wheel 214 can also reduce safety risks caused by frequent handling. Operators do not need to touch and carry heavy objects too much, reducing the risk of injury due to improper operation or accidental falls.

[0039] Working principle: When the user uses the device, he can move the device to a designated position. At this time, the user can put the material to be processed and degraded into the interior of the degradation barrel 1. At this time, the user can start the motor 21. The motor 21 drives the first bevel gear 22 on the outer side of its main shaft to rotate. During the rotation of the first bevel gear 22, the second bevel gear 25 engaged with the first bevel gear 22 is driven to rotate. During the rotation of the second bevel gear 25, the third bevel gear 27 is driven to rotate. During the rotation of the first bevel gear 22, the first connecting rod 23 is driven to rotate. During the rotation of the third bevel gear 27, the second connecting rod 26 is driven to rotate, thereby causing the first connecting rod 23 to rotate inside the second connecting rod 26. When the first connecting rod 23 rotates, it drives the first connecting rod 23 to rotate. The plurality of fifth bevel gears 212 on the outer side of the end portion of the connecting rod 23 rotate, and the rotation of the fifth bevel gear 212 will simultaneously drive the plurality of fourth bevel gears 210 on the inner side of the rotating frame 28 to rotate, thereby driving the stirring blade 211 on the outer side of the end portion of the fourth bevel gear 210 to rotate itself. When the second connecting rod 26 rotates, the stirring blade 211 will be driven to perform circular motion through the rotating frame 28. The coaxial stirring assembly 2 makes the stirring more sufficient and the mixing between the materials more uniform by the superposition of the self-rotation and circular motion of the stirring blade 211. This dual rotation method helps to break the formation of the fluid layer and the solid layer, promotes mass transfer and reaction between different components, thereby improving the rate and efficiency of the Fenton reaction. Due to the more uniform stirring, the Fenton reagent Fe2 +The organic matter in the H2O2 and ammonia water can contact and react more fully, avoiding the situation of local over-reaction or under-reaction, making the degradation of organic matter in the entire reaction system more uniform.

The design of the coaxial stirring mechanism can reduce the vibration and noise generated during the stirring process, improve the stability and service life of the equipment, and at the same time, a stable stirring environment is also helpful. To ensure the stable progress of the Fenton reaction, the fan holes 213 are provided on the stirring blades 211 in the device for degrading organic matter in ammonia water by the Fenton method, which can bring many significant benefits. First, the design of the fan holes 213 helps to increase gas exchange and solubility during the stirring process, thereby increasing the dissolved oxygen content in the reaction system, thereby enhancing the oxidation capacity of the Fenton reaction. Second, the fan holes 213 can reduce the weight of the stirring blades 211, reduce energy consumption during the stirring process, and improve the stirring efficiency, making the stirring more uniform and efficient. In addition, the fan holes 213 can also promote the flow and turbulence of the reaction liquid during the stirring process, enhance the mixing and contact opportunities of the reactants, and further accelerate the oxidation degradation process of the organic matter. These benefits combined have significantly improved the treatment efficiency, energy consumption control, and organic matter degradation effect of the Fenton method device for degrading organic matter in ammonia water.
