Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, and in particular to a water treatment flotation device. Background Technology
[0002] A water treatment flotation device is a device that purifies water quality through the synergistic effects of flocculation, dissolved air, and sludge scraping.
[0003] Existing water treatment flotation devices generally consist of a dissolved air system, a flotation tank, a release device, and a scum scraper. During operation, the dissolved air system pressurizes air into the dissolved air tank, allowing water and air to mix thoroughly to form dissolved air water. Then, the release device depressurizes and releases tiny bubbles. These bubbles adsorb suspended particles in the water and float to the surface to form scum, which is then scraped off by the scum scraper to purify the water.
[0004] In the existing water treatment flotation devices, the dissolved air system has high energy consumption, the release device is prone to clogging by suspended solids, reducing efficiency, bubbles tend to aggregate and grow larger, leading to a decrease in purification effect, and the scraper often suffers from incomplete scraping or excessive water carryover due to height adjustment issues. The air compressor, return pump, and other equipment in the dissolved air system have high energy consumption, increasing operating costs. At the same time, the release device and packing are easily clogged by suspended solids in the water, affecting the dissolved air efficiency. During scraping, incomplete scraping and excessive wastewater carryover are common, and the scraping efficiency is greatly affected by water quality. The overall operating efficiency and stability need to be improved. Therefore, a water treatment flotation device is proposed to solve the above problems. Utility Model Content

[0033] 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.
[0034] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of a water treatment flotation device, comprising a housing 6, an inlet pipe 18 installed inside the housing 6, a pair of pipes 3 on the inlet pipe 18, a flocculation tank 1 and a coagulation aid tank 2 on the left side of the housing 6, a dissolved air tank 4 on the outer wall of the housing 6, a water dissolving pump 5 fixedly connected to one side of the dissolved air tank 4, a dissolved air pipe 10 fixedly connected to the top of the dissolved air tank 4, a pressure reducing device 19 installed at one end of the dissolved air pipe 10, a water dissolving pipe 11 fixedly connected to one side of the water dissolving pump 5, a water inlet 7 on one side of the housing 6, a blockage cleaning component 8 installed inside the water inlet 7, a motor 12 on one side of the housing 6, a scraper 13 fixedly connected to the output end of the motor 12, and a waste disposal unit near the scraper 13 on one side of the housing 6. The waste residue box 14 has an inclined chute 15 directly below it. The waste residue box 14 is slidably connected to a pull-out partition 16. The blockage cleaning component 8 is located directly below a collection component 9. The pressure relief release device 19 is fixedly connected to a water dissolving pipe 11 directly below it. The end of the pressure relief release device 19 away from the dissolved air pipe 10 is fixedly connected to the water dissolving pipe 11. The tank body 6 has an outlet 17 on the side away from the inlet 7. The pull-out partition 16 is used to control the connection and disconnection between the waste residue box 14 and the inclined chute 15. The dispensing pipe 18 has several evenly distributed dispensing holes facing the water flow direction inside the tank body 6. The flocculation tank 1 and the coagulation aid tank 2 are both connected to the dispensing pipe 18 through pipes 3. The scraper 83 is fixedly connected to the bottom of the electric push rod 86.
[0035] Specifically, after the water flows into the square channel 81 from the inlet 7, large suspended particles and fibrous impurities in the water are intercepted on the outer surface of the filter screen 82 facing the inlet 7. The filtered water then flows into the housing 6 through the pores of the filter screen 82, completing the initial purification. As the filtration time increases, the impurities accumulated on the filter screen 82 gradually increase, causing partial blockage of the inlet 7 and resulting in low overall water intake efficiency. At this time, the electric push rod 86 at the top of the square channel 81 is activated, pushing the scraper 83 sleeved on the limit rod 84. The scraper 83 slides back and forth along the limit rod 84. During the sliding process, the blade makes close contact with the surface of the filter screen 82, scraping off the impurities attached to the outer surface of the filter screen 82. Under the pushing force of the scraper 83 and its own gravity, the scraped impurities fall into the slope 85 at the bottom of the square channel 81, realizing the automatic cleaning of impurities on the surface of the filter screen 82 and avoiding filter screen blockage caused by long-term accumulation of impurities. This combined effect ensures that the inlet 7 is always unobstructed, the water intake efficiency is stable, the labor cost is reduced, and the water treatment process is reduced due to downtime for cleaning. This helps to improve the continuous operation capability and treatment efficiency of the entire water treatment flotation device.
[0036] Reference Figure 3 and Figure 4 The collection component 9 includes a collection box 91, which is fixedly installed directly below the square channel 81. A handle 92 is fixedly installed on the outer wall of the collection box 91. A pull-out partition 93 is provided on the top of the collection box 91. Slide rails 94 are provided on both sides of the collection box 91, and limit plates 95 are installed at both ends of the slide rails 94.
[0037] Specifically, after the impurities on the filter screen 82 are scraped off to the slope 85 at the bottom of the square channel 81, the impurities slide down the slope 85 under the action of gravity and fall into the collection box 91 directly below. As the impurities accumulate, the operator pulls the handle 92, causing the handle 92 to pull the collection box 91 outward along the slide rail 94. The pull-out partition 93 is completely separated from the opening at the bottom of the square channel 81. Pulling the pull-out partition 93 outward cleans the impurities in the collection box 91. After cleaning, the collection box 91 and the pull-out partition 93 are pushed back to their original positions, so that the pull-out partition 93 is aligned with the opening at the bottom of the square channel 81 and sealed. This achieves centralized collection and convenient cleaning of filtered impurities, and also prevents sewage from overflowing during the cleaning process. This comprehensive approach makes the impurity collection process orderly and controllable, avoids secondary pollution caused by the scattering of impurities, helps to improve the cleanliness and maintenance efficiency of the entire water treatment flotation device, and ensures the long-term stable operation of the device.
[0038] Working principle: First, when sewage flows into the square channel 81 from the inlet 7, large suspended particles and fibrous impurities in the water are intercepted outside the filter screen 82 when passing through the filter screen 82. The filtered water enters the tank 6 through the pores of the filter screen 82 to complete the initial purification. As the filtration time increases, the impurities accumulated on the filter screen 82 gradually increase, causing the inlet 7 to become blocked. At this time, the electric push rod 86 at the top of the square channel 81 is activated, pushing the scraper 83 sleeved on the limit rod 84 to slide back and forth along the limit rod 84. During the back and forth sliding process, the scraper 83 is in close contact with the surface of the filter screen 82, scraping off the attached impurities. The scraped impurities fall into the slope 85 at the bottom of the square channel 81 under the action of the push of the scraper 83 and its own gravity.
[0039] Next, after the impurities on the filter screen 82 are scraped off to the slope 85 at the bottom of the square channel 81, the impurities slide down the slope 85 under the action of gravity and fall into the collection box 91 directly below through the bottom opening of the square channel 81. As the impurities continue to accumulate, the operator pulls the handle 92, so that the handle 92 is pulled out along the slide rail 94 to pull out the collection box 91. At this time, the pull-out partition 93 is completely separated from the bottom opening of the square channel 81. Pull the pull-out partition 93 outward to clean the impurities in the collection box 91. After cleaning, push the collection box 91 and the pull-out partition 93 back to their original positions so that the pull-out partition 93 is re-aligned with the bottom of the square channel 81 and sealed.
[0040] 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.
