Description

Technical Field

[0001] This utility model relates to the field of organic waste treatment technology, and in particular to a combined air flotation device. Background Technology

[0002] Air flotation devices, as key equipment in wastewater treatment, are widely used in industrial wastewater treatment, municipal sewage treatment, and drinking water purification. Their working principle involves introducing microbubbles into the water, causing the bubbles to adhere to suspended particles and form a floating mass with a density less than water, thus achieving solid-liquid separation. This treatment method offers advantages such as high efficiency, small footprint, and simple operation, and is particularly suitable for treating wastewater containing oil, papermaking wastewater, and dyeing wastewater, as well as other wastewater containing light suspended solids or grease.

[0003] In existing air flotation systems, continuous stirring or periodic manual stirring is typically used in the reagent storage and dosing systems to prevent reagent sedimentation. Continuous stirring uses a motor-driven agitator to keep the reagent in a flowing state; periodic manual stirring relies on operators to stir the reagent at regular intervals. In the reagent dosing stage, metering pumps are often used to directly inject the reagent into the wastewater, and the turbulence of the water flow achieves mixing between the reagent and the wastewater.

[0004] While continuous stirring can prevent reagent sedimentation to some extent, long-term operation increases energy consumption and equipment wear. Regular manual stirring has problems such as untimely stirring and unstable stirring effect, making it difficult to ensure that the reagent remains in a uniform state throughout the entire storage period. These problems directly lead to frequent reagent sedimentation and clumping, resulting in large fluctuations in the concentration of flocculant added to the wastewater and affecting the stability of the flocculation effect. Therefore, a combined air flotation device is proposed to solve the above problems. Utility Model Content

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.

[0034] Reference Figures 1-4This utility model provides an embodiment of a combined air flotation device, including a support frame 1. A filter box 2 is fixedly connected inside the support frame 1. The filter box 2 is the core container for air flotation treatment, and its interior is divided into different functional areas for completing processes such as flocculation reaction, air mixing, and solid-liquid separation. A water inlet pipe 3 is fixedly connected to one side of the filter box 2, used to introduce wastewater to be treated into the filter box 2. A stirring assembly is installed on the side wall of the filter box 2. A drain pipe 10 is fixedly connected to the other side of the filter box 2, used to discharge the clean water after air flotation treatment, achieving water discharge after solid-liquid separation. A filter frame 11 is installed inside the filter box 2, used to intercept suspended impurities, scum, and other solid substances generated during the treatment process, preventing... The filter frame 11 is equipped with a fixed component on its side wall to prevent it from being discharged with the clean water from the drain pipe 10. The stirring component includes a rotating shaft 15. A fixed frame 12 is fixedly connected to the side wall of the filter box 2. A chemical storage tank 13 is fixedly connected inside the fixed frame 12. The chemical storage tank 13 is used to store the chemicals required for the flotation treatment, such as flocculants, to provide a source of chemicals for subsequent mixing and reaction with sewage. A connecting frame 14 is fixedly connected to the bottom of the chemical storage tank 13. The rotating shaft 15 is rotatably connected to the side wall of the chemical storage tank 13 and the connecting frame 14. A full gear 16 is fixedly connected to the side wall of the rotating shaft 15. A half gear 17 is rotatably connected inside the connecting frame 14. A second motor 18 is fixedly connected to the side wall of the connecting frame 14. The output end of the second motor 18 is connected to the half gear 17. The rotating shaft 15 is fixedly connected to the side wall of the filter box 2. A stirring blade 19 is attached, and a second motor 18 drives a half gear 17 to rotate. Through intermittent meshing with a full gear 16, the half gear 17 rotates periodically, causing the stirring blade 19 to generate water flow within the storage tank 13. This enhances the mixing effect of the chemicals and prevents sedimentation and clumping. A first motor 4 is installed inside the filter box 2, with a stirrer 5 fixedly connected to its output. The stirrer 5 is rotatably connected to the side wall of the filter box 2's flocculation reaction zone. The first motor 4 drives the stirrer 5 to rotate, mixing the wastewater and chemicals entering the flocculation reaction zone of the filter box 2. This promotes full contact between the flocculant and suspended particles in the wastewater, accelerates the flocculation reaction, and forms larger flocs, facilitating subsequent air flotation separation. A dissolved air pump 6 is fixedly connected to the side wall of the support frame 1, and the dissolved air pump 6 outputs air. An exhaust pipe 7 is fixedly connected to the outlet, and the nozzle of the exhaust pipe 7 is fixedly connected to the air mixing zone of the filter box 2. The dissolved air pump 6 pressurizes and dissolves air in water to form dissolved air water. Microbubbles are released through the nozzle of the exhaust pipe 7. After the microbubbles combine with the flocs, they float to the water surface, realizing solid-liquid separation. A scraper 8 is slidably connected inside the filter box 2. A hydraulic rod 9 is fixedly connected to the side wall of the filter box 2. The output end of the hydraulic rod 9 is connected to the scraper 8. The hydraulic rod 9 drives the scraper 8 to move horizontally and scrape the scum on the water surface into the scum discharge trough. By starting the hydraulic rod 9 at a time, the scum can be continuously removed to prevent the scum from sinking back into the water. The full gear 16 is rotatably connected to the inside of the connecting frame 14. The half gear 17 meshes with the full gear 16. The stirring blade 19 is rotatably connected to the inside of the storage tank 13.

[0035] Reference Figure 2 and Figure 5 The fixing components include a slide rail 21, which provides a sliding track for the filter frame 11, facilitating its installation, disassembly, and cleaning. It also ensures the filter frame 11 remains stable within the filter box 2, preventing it from shaking and affecting the filtration effect. The slide rail 21 is fixedly connected to the inside of the filter box 2, and the filter frame 11 is slidably connected to the side wall of the slide rail 21. A fixing hole 20 is provided inside the filter frame 11, which covers the water inlet of the drain pipe 10. A locking block 22 is slidably connected inside the slide rail 21, and its side wall is slidably connected to the fixing hole 20. The locking block 22 is used to insert the filter frame 11. The fixing hole 20 of the filter frame 11 is used to fix the filter frame 11 on the slide rail 21 to prevent the filter frame 11 from sliding or shifting in the filter box 2. The side wall of the locking block 22 is fixedly connected to the limiting block 23, and the side wall of the limiting block 23 is slidably connected inside the slide rail 21. The limiting block 23 is used to limit the sliding range of the locking block 22 to prevent the locking block 22 from sliding out of the slide rail 21, and at the same time to provide guidance for the locking block 22. A spring 24 is fixedly connected inside the slide rail 21, and the side wall of the spring 24 is fixedly connected to the side wall of the limiting block 23. The spring 24 pushes the locking block 22 into the fixing hole 20 of the filter frame 11, locking the filter frame 11 on the slide rail 21.

[0036] Working principle: The wastewater to be treated flows into the filter box 2 through the inlet pipe 3. The filter box 2 is divided into a flocculation reaction zone, a gas mixing zone, and a solid-liquid separation zone. In the flocculation reaction zone, motor 4 drives the agitator 5 to rotate, so that the wastewater and the flocculant transported in the storage tank 13 are fully mixed, causing the suspended particles in the wastewater to aggregate into larger flocs. The flocculant in the storage tank 13 is kept in a uniform state by the stirring components. Motor 18 drives the half gear 17 to rotate, and through intermittent meshing with the full gear 16, drives the rotating shaft 15 to rotate periodically, so that the stirring blades 19 move in the storage tank. Water flow is formed in the medicine tank 13 to prevent the medicine from settling and clumping, ensuring uniform concentration and flocculation effect. Then, the dissolved air pump 6 pressurizes and dissolves air to make dissolved air water, which is released into the mixed air mixing zone through the nozzle of the exhaust pipe 7. After the microbubbles combine with the flocs, they float to the water surface due to buoyancy and form scum. The hydraulic rod 9 drives the scraper 8 to move periodically to scrape off the scum, reducing the amount of scum re-entering the water. The treated clean water passes through the filter frame 11 covering the water inlet of the drain pipe 10 to further intercept residual suspended impurities before being discharged, thus achieving sewage purification.

[0037] When installing the filter frame 11, push it in along the slide rail 21. At this time, the locking block 22 is squeezed into the slide rail 21 by the filter frame 11, causing the limiting block 23 to squeeze the spring 24. When the filter frame 11 is fully inserted, the locking block 22 is aligned with the fixing hole 20. The spring 24 rebounds and pushes the limiting block 23 to drive the locking block 22 to insert into the fixing hole 20 in the filter frame 11, thereby fixing the filter frame 11 on the slide rail 21. When it is necessary to disassemble the filter frame 11 for cleaning or replacement, pull it outward to make the locking block 22 retract and squeeze the spring 24, so that the locking block 22 is disengaged from the fixing hole 20, and the filter frame 11 can be pulled out along the slide rail 21.

[0038] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
