Embodiment 1

[0026] see Figure 1-5 , an aeration device for sewage treatment, comprising an aeration box 1, a liquid inlet pipe 14 and a liquid outlet pipe 13 are installed on the aeration box 1, a hollow shaft 10 is installed in the aeration box 1 for rotation, and the aeration box 1 is provided with There is an air blowing mechanism, and the bellows 5 connected to the hollow shaft 10 through a rotary joint is installed on the air blowing device. Several aeration components are installed on the hollow shaft 10, and a rotating shaft is connected to the hollow shaft 10 through a transmission assembly. Plate 18, a stirring mechanism is installed on the rotating plate 18, a transmission box 2 is fixed on the top of the aeration box 1, and a driving mechanism for driving the hollow shaft 10 to rotate is arranged in the transmission box 2.

[0027] The sewage that needs to be purified can be injected into the inside of the aeration tank 1 through the liquid inlet pipe 14. The liquid outlet pip...

Embodiment 2

[0032] On the basis of Embodiment 1, further, the agitating assembly of the device includes a rotating plate 18 that is rotated, and a rotating shaft 9 is pivotally connected to the rotating plate 18, and several rotating plates 7 are fixed at equal intervals on the rotating shaft 9, and the rotating plates 7 A through hole 8 is opened on the top, and the agitation assembly also includes a transmission gear 21 sleeved and fixed on the rotating shaft 9 , and the transmission gear 21 is meshed with an inner ring gear 15 fixed on the inner wall of the aeration box 1 .

[0033] When the rotating plate 7 rotates, the rotating plate 7 drives the rotating shaft 9 on it to rotate, and the transmission gear 21 on the rotating shaft 9 meshes with the inner ring gear 15 for transmission, and then realizes rotating the rotating shaft 9 while driving the rotating plate 7 to rotate, which promotes spraying from the nozzle. 11 The dispersion effect of the sprayed air improves the aeration eff...

Abstract

The invention discloses a sewage treatment aeration device, and relates to the technical field of sewage treatment. The aeration device comprises an aeration box, a liquid inlet pipe and a liquid outlet pipe are arranged on the aeration box, a hollow shaft is rotationally arranged in the aeration box, an air blowing mechanism is arranged on the aeration box, a corrugated pipe connected with a hollow shaft through a rotary joint is arranged on an air blowing device, and a driving mechanism for driving the hollow shaft to rotate is arranged in a transmission box. The air blowing mechanism can blow air into the hollow shaft, and aeration operation is carried out on the sewage in the aeration box by air through aeration assemblies. A rotating plate in a stirring mechanism can rotate around a rotating shaft in a stepping manner and can also rotate around the hollow shaft, sufficient stirring of sewage is achieved, air dispersion is promoted, and the aeration effect is improved. A transmission mechanism can drive the stirring mechanism to reciprocate vertically, the sufficient air dispersion effect is further improved, and the sewage treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an aeration device for sewage treatment. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. Aeration is to make air and water strong A means of contact whose purpose is to dissolve oxygen in the air in the water, or to release unwanted gases and volatile substances from the water into the air. In other words, it is a means of facilitating the exchange of substances between gases and liquids. It also has several other important functions, such as mixing and stirring. The oxygen in t...
