Abstract

The invention provides a T-shaped submersible mixer. The T-shaped submersible mixer comprises a submersible motor, a thrust bearing assembly, a steering gear box, a second impeller, a first impeller and a third impeller. The submersible stirrer can stir in three directions at the same time, jet flow ejected by the third impeller collides with the bottom ground close to the third impeller, and the impact jet flow phenomenon occurs. The jet flow ejected by the first impeller in the horizontal direction enables the impact jet flow phenomenon caused by the lower impeller to be more violent, the mixing effect of a flow field is enhanced, mixing is more uniform and rapid, and the actual efficiency of the stirrer is improved. The second impeller on the upper portion can guarantee circulation of fluid on the upper portion, the oxygen exchange rate of sewage can be increased for part of aerobic sewage stirring pools, and the overall purification rate is increased. Through simple structural improvement, the stirring efficiency and the stirring effect of the submersible stirrer are improved, energy can be saved, and the equipment cost and the operation cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of mixers, in particular to a T-shaped submersible mixer. Background technique [0002] Submersible mixer, also known as sewage treatment mixer or submersible mixer, is a mixing machine mainly used for sewage treatment. It plays the role of mixing, stirring and circulation in the sewage treatment process of municipal, industrial and urban residents. [0003] Most of the existing submersible mixers use a submersible motor to directly drive an impeller, so they can only stir in one direction. It usually takes a long time to make the overall mixing even, resulting in a large amount of power loss. [0004] For some larger sewage treatment plants, when a submersible mixer is used, only a part of the liquid is circulated, and the activated sludge or suspended solids in other parts of the tank may settle. In order to avoid this situation, large-sized submersible mixers are usually replaced, or the number of submer...
