Embodiment approach
[0028] like figure 2 As shown, the aeration pipes 4 are generally made of rubber material. For medium and large aeration tanks 1 in the sewage treatment plant, due to the large area of the aeration tank 1, the aeration pipes 4 are very long in the aeration tank 1. It is long and easy to bend, and the mode of driving the aeration tube 4 to rotate by arranging a rotating shaft in the middle of the pool body cannot actually be realized, and the aeration tube 4 will be greatly deformed. In this way, by arranging multiple sets of rotary drive components, the outside of the swivel 2 is driven by the swivel 2, thereby driving all the aeration pipes 4 to rotate together. As an embodiment, the rotary drive assembly includes a roller and a friction layer disposed between the roller and the swivel 2 , and the friction layer is fixed on the surface of the roller and / or the outer side of the swivel 2 The first gear motor 12 is hinged on the mounting plate 14, and a spring is arranged b...

The invention relates to an environment-friendly sewage aeration device, which comprises a cylindrical aeration tank and a swivel ring arranged at the bottom of the aeration tank, the swivel ring rotates under the action of a rotary drive device, and the middle part of the swivel ring is provided with A distribution chamber, a number of aeration pipes are arranged between the swivel and the distribution chamber, and the distribution chamber is connected with an air supply pipe through a rotary joint. The invention provides an environment-friendly sewage aeration device. The swivel ring is rotated in the rotating chamber under the action of the rotating drive device, thereby driving all the aeration pipes to rotate. Under the action of the rope, the rotating chamber can be raised and lowered. In this way, the rotating ring and the aeration tube are driven up and down. While aerating, the rotating aeration tube can stir the sewage to make the aeration effect better. It can realize all-round stirring and aeration in the aeration tank to ensure the aeration Sufficient oxygen content in the upper part of the aeration tank narrows the gap between the upper and lower aeration levels of the aeration tank and greatly improves the aeration effect.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an environmental protection sewage aeration device. Background technique [0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. A certain sewage residence time is provided in the pool to meet the oxygen required by aerobic microorganisms and the mixing conditions for the full contact between sewage and activated sludge. The aeration tank is mainly composed of three parts: the tank body, the aeration system and the water inlet and outlet. The pool body is generally made of reinforced concrete, and the plane shape is rectangular, square and circular. The utility model with the publication number CN210595476U provides an aeration tank with a ladder-type aeration pipe for sewage treatment. By being provided with a ladder-type aeration pipe assembly, etc., the aeration motor supplies the aeration main pipes on both ...
