Embodiment approach
[0028] Such as figure 2 As shown, the aeration pipe 4 is generally made of rubber material. For the medium and large aeration tanks 1 in the sewage treatment plant, because the area of the aeration tank 1 is very large, the length of the aeration tube 4 in the aeration tank 1 is very large. It is long and prone to bending. The method of driving the aeration tube 4 to rotate by setting 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 setting multiple sets of rotating drive components, with the help of the swivel 2, the outer side of the swivel 2 is driven, thereby driving all the aeration pipes 4 to rotate together. As an embodiment, the rotary driving assembly includes a roller and a friction layer arranged between the roller and the swivel 2, and the friction layer is fixed on the surface of the roller and / or the outer surface of the swivel 2 above; the geared motor 12 is hinged ...

The invention relates to an environment-friendly sewage aeration device which comprises a cylindrical aeration tank and a rotating ring arranged at the bottom of the aeration tank, the rotating ring rotates under the action of a rotating driving device, a flow dividing bin is arranged in the middle of the rotating ring, a plurality of aeration pipes are arranged between the rotating ring and the flow dividing bin, and the flow dividing bin is connected with an air supply pipe through a rotating joint. According to the environment-friendly sewage aeration device provided by the invention, a rotating ring rotates in a rotating bin under the action of a rotating driving device so as to drive all aeration pipes to rotate, the rotating bin can ascend and descend under the action of a rope I so as to drive the rotating ring and the aeration pipes to ascend and descend, and the aeration efficiency is improved while aeration is performed. The rotating aeration pipe can stir sewage, so that the aeration effect is better, all-directional stirring and aeration in the aeration tank can be realized, sufficient oxygen content at the upper part of the aeration tank is ensured, the difference between the upper aeration degree and the lower aeration degree of the aeration tank is reduced, and the aeration effect is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an environment-friendly 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 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 its planar shape is rectangular, square and circular. The utility model whose publication number is CN210595476U provides an aeration tank with ladder-type aeration pipes for sewage treatment. By setting up ladder-type aeration pipe components, the aeration motor supplies the aeration main pipes on both sides simultaneously. ...
