Problems solved by technology

This technical solution utilizes the air intake hole at the upper end of the shell and the water inlet hole at the lower end, and mixes air and water through the air-dissolving pump head, and the paddle breaks it up to achieve the purpose of rapid oxygenation, but it does not pressurize the air. , in order to aerate under normal pressure, the efficiency is low, and it needs to set the dissolved air pump head, the structure is complicated, the cost is high, and it needs to be improved

Abstract

The invention relates to a turbofan-pressurized plug-flow aerator and belongs to the technology of sewage plug flow and oxygenation. The turbofan-pressurized plug-flow aerator comprises a turbofan shell, a motor which is hermetically connected with the upper end of the turbofan shell, a pressurizing turbine connected with the main shaft of the motor through a coupler, a propeller shaft fixedly connected with the pressurizing turbine and a protective hood, wherein the pressurizing turbine is arranged in the turbofan shell, the propeller shaft extends out of the lower end of the turbofan shell, the protective hood sheathes the propeller shaft and is hermetically connected with the lower end of the turbofan shell, one side of the turbofan shell is connected with an air inlet seat communicated with the inner cavity of the turbofan shell, the air inlet seat is provided with an air inlet hole, the propeller shaft is a hollow shaft pipe, a pressure air inlet hole is formed at the end close to the pressurizing turbine, and a plug flow aerating blade is arranged at the tail end of the propeller shaft. The turbofan-pressurized plug-flow aerator is low in equipment manufacturing cost and has higher oxygenation efficiency than foreign advanced equipment.

Description

technical field [0001] The present invention is applicable to various fields such as urban sewage, chemical sewage, food industry, papermaking sewage and other waste water, or small lakes and oxidation ponds, and the like. It belongs to the category of sewage push flow and aeration technology. It mainly relates to an integrated technology of air pressurization, sewage push flow, sewage aeration and oxygen enhancement. Background technique [0002] The turbofan supercharged push-flow aerator refers to that the air is pressurized by the turbofan and then sucked out by the push-flow impeller under negative pressure. After stirring, it is fully mixed with the sewage to form bubbles with a diameter of less than 1mm, and exchange oxygen with the sewage. And push the sedimented sludge at the bottom to mix with the sewage. [0003] At present, domestic and foreign sewage push flow aeration aerators are generally divided into several process methods [0004] 1. Separately equipped...
