Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an integrated aeration device. Background Technology

[0002] In wastewater treatment processes, aeration devices are core equipment for ensuring efficient biochemical reactions. Their primary function is to achieve thorough mixing of wastewater with air (or oxygen) and rapidly increase the dissolved oxygen content in the wastewater. Sufficient dissolved oxygen provides a suitable living environment for aerobic microorganisms, promoting their decomposition and metabolism of harmful substances such as organic pollutants and ammonia nitrogen. The aeration uniformity, oxygen utilization rate, and energy consumption of the aeration device directly determine the wastewater purification efficiency, the stability of treatment compliance, and operating costs, making them key factors affecting wastewater treatment effectiveness and overall process economics.

[0003] Existing aeration devices typically only achieve the mixing of wastewater and gas and the increase of dissolved oxygen, lacking the ability to pre-treat wastewater. The suspended particulate matter often contained in wastewater can easily damage the aeration components, increasing the operating load and maintenance costs of the equipment. Therefore, we propose an integrated aeration device to solve the above problems. Utility Model Content

Through the cooperation of the cylinder 14 and the pressure plate 15, the cylinder 14 drives the pressure plate 15 to press down, which can pressurize the sewage and improve the decontamination efficiency. Through the threaded connection between the cover plate 5 and the filter barrel 2, the cover plate 5 can be quickly disassembled, which is convenient for subsequent filter screen replacement. By setting the water conveying assembly 6, the filtered sewage in the filter barrel 2 can be transported to the housing 8 for aeration treatment.

[0024] The water transport assembly 6 includes a water pump 601, which is mounted on the upper surface of the housing 8. The input end of the water pump 601 is fixedly connected to a water suction pipe 602, and the left end of the water suction pipe 602 is connected to the outer surface of the filter bucket 2. The output end of the water pump 601 is fixedly connected to a water delivery pipe 603, and the bottom end of the water delivery pipe 603 is connected to the upper surface of the housing 8. Through the cooperation of the water pump 601, the water suction pipe 602 and the water delivery pipe 603, the water pump 601 draws the filtered sewage from inside the filter bucket 2 through the water suction pipe 602, and the sewage enters the interior of the housing 8 through the water delivery pipe 603.

[0025] The stirring assembly 7 includes a rotary motor 701, which is mounted on the upper surface of the housing 8. A rotating rod 702 is rotatably connected to the inner wall of the housing 8 via bearings. The output end of the rotary motor 701 is connected to the top end of the rotating rod 702 via bearings. Multiple sets of stirring rods 703 are fixedly connected to the outer surface of the rotating rod 702.

[0029] A drain pipe 17 is fixedly connected to the outer surface of the outer casing 8. A second valve 18 is fixedly installed on the outer surface of the drain pipe 17. By cooperating with the drain pipe 17 and the second valve 18, turning the second valve 18 can allow the treated sewage to be discharged in a timely manner through the drain pipe 17.

[0030] An air inlet pipe 19 is fixedly connected to the upper surface of the outer casing 8. A flange 20 is fixedly connected to the top end of the air inlet pipe 19. Through the cooperation of the air inlet pipe 19 and the flange 20, it can be connected to an external pipeline, so that gas can enter the interior of the outer casing 8 through the air inlet pipe 19.

[0031] The working principle of this utility model is as follows: When in use, turn on the first valve 4 to allow sewage to enter the interior of the filter bucket 2 through the inlet pipe 3. The sewage passes through the third filter screen 12, the second filter screen 11, and the first filter screen 10 in sequence to complete three-stage filtration, filtering impurities of different particle sizes. Then, the cylinder 14 drives the pressure plate 15 to move downward, causing the pressure plate 15 to squeeze the sewage, allowing the sewage to pass through the filter screen quickly and improving the filtration efficiency. After that, the water pump 601 is started. The water pump 601 draws the filtered sewage from the filter bucket 2 through the water suction pipe 602. The filtered sewage enters the interior of the outer shell 8 through the water delivery pipe 603. At the same time, gas enters the outer shell 8 through the air inlet pipe 19. Finally, the rotary motor 701 drives the rotating rod 702 to rotate. The rotating rod 702 drives the stirring rod 703 to rotate. The stirring rod 703 stirs the sewage and gas to fully mix, completing the aeration and oxygenation process.
