Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an environment-friendly air flotation machine for wastewater treatment. Background Technique

[0002] Wastewater treatment refers to the process of treating sewage generated in industrial, agricultural, and domestic production processes, removing pollutants therein, and making it meet environmental discharge standards or water quality requirements for reuse. Common wastewater treatment methods include physical methods, chemical methods, or biological methods. These methods provide important support for environmental protection and resource reuse through various equipment and technologies.

[0003] During the process of wastewater treatment, an air flotation machine is required. The air flotation machine can effectively remove suspended substances in wastewater, such as suspended solids, grease, and sludge. When the wastewater enters the interior of the air flotation machine, the aerator will inject air bubbles into the wastewater. At this time, the impurities in the wastewater will be included by the air bubbles and suspended on the water surface. Subsequently, the scraping device inside the air flotation machine will scrape the suspended substances on the water surface. However, due to the certain adhesiveness of the air bubbles in the suspended substances, they are easily adhered to the surface of the scraper. As a result, after the scraper transports the suspended substances to the designated storage position, the suspended substances cannot completely fall off and return to the wastewater with the scraper, which will affect the treatment quality of the wastewater. At the same time, the aeration pipes inside the traditional air flotation machine are usually arranged in a single row. Therefore, uniform distribution of air bubbles may not be achieved in the entire wastewater treatment tank, which may lead to too many or too few air bubbles in some areas, affecting the uniformity and stability of the air flotation effect.

[0004] Therefore, in view of the above problems, we need to propose an environment-friendly air flotation machine for wastewater treatment. Content of the Utility Model

The aerator 2 is located on the right side of the top of the partition board 7, and its function is to cooperate with the exhaust pipe 3 to inject air flow into the wastewater, so that bubbles suspend impurities to the surface of the wastewater. One side of the aerator 2 is communicated with an exhaust pipe 3. An adding pipe 12 is communicated with the left side of the top of the box body 1. The adding pipe 12 is located on the left side of the top of the box body 1, and its function is to facilitate the staff to add the medicament required for wastewater treatment. A limiting plate 6 is fixedly connected to the right side of the inner cavity of the box body 1. The front side of the bottom of the partition board 7 is communicated with a feed pipe 10. A baffle is fixedly connected to the left side of the bottom of the inner cavity of the box body 1. A stirring member 8 capable of mixing and stirring the medicament is arranged on the left side of the top of the inner cavity of the box body 1; a scraping assembly 11 is arranged in the inner cavity of the box body 1 and at the bottom of the partition board 7, which can clean the suspended matter on the surface of the wastewater.

[0023] The scraping assembly 11 includes a motor 1101. The front side of the motor 1101 is fixedly connected to the box body 1. The output end of the motor 1101 penetrates into the inner cavity of the box body 1 and is fixedly connected to a first driving wheel 1102. A transmission belt 1103 is arranged on the surface of the first driving wheel 1102. A second driving wheel 1104 is arranged on one side of the inner cavity of the transmission belt 1103. Through the cooperation of the motor 1101, the first driving wheel 1102, the transmission belt 1103 and the second driving wheel 1104, the scraping plate 1105 can be displaced to scrape the suspended matter on the surface of the wastewater.

[0024] A scraping plate 1105 is arranged on the surface of the transmission belt 1103. The scraping plate 1105 is located on the surface of the transmission belt 1103, and its function is to scrape and clean the impurities and suspended matter on the surface of the wastewater. The material of the scraping plate 1105 is rubber.

[0025] A fixed plate 9 is fixedly connected to the left side of the inner cavity of the box body 1. The fixed plate 9 is located on the left side of the inner cavity of the box body 1. Its function is to cooperate with the toggle plate 13 to knock off impurities and suspended matter on the surface of the scraper plate 1105, so as to prevent the suspended matter from not completely detaching from the surface of the scraper plate 1105 and being brought back into the wastewater, thereby affecting the wastewater treatment effect. One side of the fixed plate 9 is fixedly connected to the toggle plate 13 by a torsion spring.

[0026] The bottom of the exhaust pipe 3 is connected to an aeration pipe 4, which is located at the bottom of the exhaust pipe 3. Its function is to evenly distribute the airflow in the wastewater through multiple settings to improve the treatment efficiency of impurities in the wastewater.

[0028] Working principle: When the staff needs to treat the wastewater, first discharge the wastewater into the interior of the box 1, and then pour the required reagents into the top of the partition 7 through the addition pipe 12, and then the stirring element 8 will mix the reagents. After mixing, it will be discharged into the wastewater inside the box 1 through the discharge pipe 10. At this time, the aerator 2 is turned on, and the aerator 2 will inject the airflow into the interior of the aeration pipe 4 through the exhaust pipe 3. At this time, the multiple aeration pipes 4 arranged in an array will inject the airflow into the wastewater, so that the impurities in the wastewater float upward through the bubbles on its surface. At this time, suspended matter will be generated on the surface of the wastewater, and then the motor 1101 will be turned on, and the output end of the motor 1101 will drive the transmission belt 11 through the first driving wheel 1102 03 is driven, and then the scraper plate 1105 will slide on the surface of the wastewater along with the transmission belt 1103, so as to scrape the suspended matter on the surface of the wastewater to the surface of the scraper plate 1105. When the scraper plate 1105 moves to the position of the toggle plate 13 along with the transmission belt 1103, the scraper plate 1105 will move downward and contact with the toggle plate 13. At this time, the toggle plate 13 will be squeezed and tilted downward, and the suspended matter and impurities on the surface of the scraper plate 1105 will be knocked down to the bottom of the left side of the inner cavity of the box body 1 by the vibration force of touching the toggle plate 13, so as to achieve the effect of collecting and cleaning the suspended matter and impurities in the wastewater, which can effectively provide convenience for the staff and reduce the manpower and time consumed by the staff to clean up the suspended matter by themselves.
