Abstract

The invention discloses a diving aerator impeller which comprises a wheel hub and blades arranged on the wheel hub. The blades are blades bended anticlockwise. The blades are sector structures. Extending lines of end lines at the end of the blades pass through the axis of the wheel hub. According to the invention, the impeller adopts the bended blades, and the whole impeller is integrally cast. In comparison with a straight-blade impeller, the impeller provided by the invention has the following advantages: air input is raised; and on the prerequisite of increasing aeration rate, energy consumption of a motor is reduced so as to save operation costs.

Description

technical field [0001] The invention relates to a submersible aerator, in particular to an impeller of a submersible aerator. Background technique [0002] The submersible aerator is a submersible motor that drives the impeller to rotate, and at the same time presses water and air into the air mixing chamber, so that the water and air are fully mixed and then sprayed out, which not only achieves the effect of dissolved oxygen, but also plays a stirring role. The hydraulic design of the impeller directly determines the efficiency of the aerator. In the prior art, straight blade impellers are generally used. For example, the Chinese utility model patent CN202482143U disclosed an improved submersible aerator impeller on October 10, 2012. It includes a hub and blades, and the blades pass through the upper and lower sides. The plate is welded on the hub: the upper and lower side plates and the blades together form the air inlet passage of the impeller, and the lower side plate i...
