Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an aeration mechanism and sewage treatment equipment. Background Art

[0002] Sewage treatment equipment is an industrial equipment that can effectively treat domestic sewage, industrial wastewater, etc. in urban areas, preventing sewage and pollutants from directly flowing into water areas. It is of great significance to improving the ecological environment, enhancing the quality of the city and promoting economic development. Buried sewage treatment equipment is suitable for domestic sewage and similar industrial organic wastewater from residential areas, hospitals and sanatoriums, office buildings, shopping malls, hotels, restaurants, government agencies, schools, military units, aquatic product processing plants, livestock processing plants, dairy processing plants, etc., and organic wastewater from industries such as textiles, beer, papermaking, leather making, food, and chemicals. The main purpose is to treat domestic sewage and similar industrial organic wastewater to meet the reuse water quality requirements, so that the treated wastewater can be used as a resource.

[0003] The Chinese patent with announcement number CN208791275U discloses an aeration tank with a dual rotary aeration mechanism, including a tank body, a fixed frame, a first motor, aeration blades, a blower, a water inlet pipe and a drain pipe. The top of the tank body is fixedly connected to the fixed frame, and the bottom of the tank body is provided with a crankshaft. The left end of the crankshaft is fixedly connected to the left worm gear, and the right end of the crankshaft is fixedly connected to the right worm gear. The left side of the tank body is fixedly connected to the second motor. The shaft extension end of the second motor passes through the side wall of the tank body and is fixedly connected to the left worm gear. The left and right sides of the second connecting rod are respectively provided with rotating shafts. The aeration blades are used to aerate the surface sewage. During the aeration process, the aeration plate rotates to stir the bottom sewage so that the sewage and bubbles are mixed more evenly, thereby improving the aeration effect. When the second motor is running, it drives the left worm gear to rotate, thereby driving the crankshaft to rotate, and then drives the sleeve to move up and down through the second connecting rod, thereby driving the aeration blades to move up and down, which is more conducive to lifting the surface sewage and improving the aeration effect.

[0004] However, the above technical solution has the following shortcomings: although multiple sets of drive mechanisms can achieve stirring and aeration of sewage and improve the aeration effect, multiple sets of drive mechanisms not only increase the cost of the equipment, but also lead to an increase in the failure rate of the equipment, and the daily operating cost and maintenance cost are high.
