Embodiment Construction

[0020] refer to figure 1 , The present invention proposes a multi-actuator sewage treatment aeration device, comprising a cylinder 1, at least one water diversion pipe 2, an aeration mechanism, and a stirring mechanism, wherein:

[0021] The cylinder 1 includes an outer casing 3 and an inner casing 4 arranged in the outer casing 3. A gap is reserved between the outer casing 3 and the inner casing 4 to form a sewage channel 5, and a plurality of spray heads 6 are distributed at the top of the inner casing 4. , the inlet of the nozzle 6 is communicated with the sewage channel 5 .

[0022] The first end of the water diversion pipe 2 is provided with a sewage suction port 7, and the second end of the water diversion pipe 2 extends into the sewage channel 5 through the outer casing 3. The water diversion pipe 2 is provided with a water pump 8, and the inner part of the water diversion pipe 2 is along its axial direction. A plurality of filters 23 are arranged at intervals.

Abstract

The invention provides a sewage treatment aeration device with a plurality of executing mechanisms. The sewage treatment aeration device comprises a barrel body, at least one water diversion pipe, an aeration mechanism and a stirring mechanism, wherein a sewage channel is formed between an outer shell body and an inner shell body of the barrel body; a second end of the water diversion pipe penetrates through the outer shell body and stretches into the sewage channel; a first rotary shaft is internally provided with an aeration cavity; a plurality of aeration pipes are distributed at the periphery of the first rotary shaft; water diversion cavities are arranged in a plurality of second rotary shafts; the quantity of the second rotary shafts is the same as that of driven gears; first ends of the plurality of second rotary shafts penetrate through the plurality of driven gears respectively and stretch into the inner shell body; a hollow shaft is fixedly connected with the driven gears; second ends of the plurality of second rotary shafts are provided with first jet flow pipes and second jet flow pipes respectively; included angles alpha are formed between the first jet flow pipes and the second jet flow pipes, and the first jet flow pipes and the second jet flow pipes are communicated with the water diversion cavities. According to the sewage treatment aeration device provided by the invention, air is uniformly dispersed in sewage by adopting two times of mixing; gas and liquid are sufficiently mixed, so that the oxygen dissolving capability of the injected air is high and the aeration efficiency is high.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multi-actuator sewage treatment aeration device. Background technique [0002] In the process of sewage treatment, it is necessary to oxygenate the sewage for the growth and reproduction of beneficial bacteria, so as to achieve the purpose of decomposing the organic matter in the sewage. Aerator is one of the more commonly used equipment in the field of sewage treatment. Its function is to inject micro-bubbles directly into the sewage, and achieve the purpose of separating suspended solids under the combined action of coagulants and flocculants. However, the structure of the currently used aerator is relatively simple, and the mixing of liquid and gas is not sufficient, resulting in a low oxygen absorption rate, which ultimately leads to an unsatisfactory or substandard sewage treatment effect. SUMMARY OF THE INVENTION [0003] Based on the technical problems existi...
