Three-impeller sewage treatment stirrer

Abstract

The invention relates to a three-impeller sewage treatment stirrer. The three-impeller sewage treatment stirrer comprises a submersible motor, a transmission device, a first impeller, a second impeller and a third impeller, wherein the transmission device comprises a first gear shaft, a second gear shaft, a third gear shaft and a fourth gear shaft; one end of the first gear shaft is in transmission connection with a motor shaft of the submersible motor; a first gear is arranged at the other end of the first gear shaft; both ends of the second gear shaft, the third gear shaft and the fourth gear shaft are fixed on a box wall of the transmission device through bearings; a second gear in the middle of the second gear shaft, a third gear in the middle of the third gear shaft and a fourth gear in the middle of the fourth gear shaft are externally meshed with the first gear respectively; the first impeller is arranged at the outer end of the second gear shaft; the second impeller is arranged at the outer end of the third gear shaft; the third impeller is arranged at the outer end of the fourth gear shaft. Under the interaction of the three impellers and the wall of a pool, the stirring width and the stirring depth are obviously increased, and the stirring effect is obviously enhanced; a motor drives the three impellers through the transmission device, so that the three-impeller sewage treatment stirrer is energy-saving, safe and reliable.

Description

technical field [0001] The invention relates to key equipment for sewage treatment in the field of environmental protection, in particular to a novel three-impeller sewage treatment mixer. Background technique [0002] With the rapid development of urbanization in my country, the discharge of urban domestic sewage is increasing rapidly. The state attaches great importance to sewage treatment and discharge. Since 1998, when the discharge of urban domestic sewage exceeded that of industrial wastewater, urban sewage treatment has developed rapidly. By the end of the third quarter of 2011, my country had built 3,078 sewage treatment plants, with a total sewage treatment capacity of 136 million tons per day. , the actual processing capacity is about 110 million tons / day. As the main sewage treatment equipment, the sewage treatment mixer is widely used in sewage treatment plants. The research on it is the key to energy saving and emission reduction in sewage treatment plants. ...
