Submersible waterpower rotation flow plug aeration machine

Abstract

The invention relates to a submersible waterpower rotation flow plug aeration machine. The aeration machine which comprises a motor (1) and a diversion elbow tube (10) is characterized in that: the motor (1) is connected with a bidirectional impeller (9) through a rotation shaft (4); the motor (1) drives the bidirectional impeller (9) to rotate; the bidirectional impeller (9) stretches into the diversion elbow tube (10); water inlet grids (3) are arranged between the diversion elbow tube (10) and the motor (1); the part of the diversion elbow tube (10) provided with the bidirectional impeller(9) is communicated with air through an air suction tube (8); a space made by the water inlet grids (3), the motor (1) and the diversion elbow tube (10) forms a mixed chamber (12); a tray (2) is arranged under the motor (1) and the diversion elbow tube (10); the tray (2) is connected with a fixed pedestal (5) through a rotation bearing (7); the rotation bearing (7) is sleeved with conducting sliprings (6); and the conducting slip rings (6) are positioned between the tray (2) and the fixed pedestal (5). The aeration machine has the advantages of free rotation under the hydraulic action, realization of multidirectional rotation aeration, simple structure, and low cost.

Description

technical field [0001] The invention relates to an aerator, in particular to a submersible hydraulic rotary push-flow aerator, which is suitable for aeration of landscape water bodies, aquaculture and sewage treatment. Background technique [0002] Landscape water is used to modify the environment, give people a sense of beauty, and maintain ecological balance. At present, landscape water is mostly closed and non-flowing stagnant water. Natural rainfall, dust in the atmosphere, intrusion of domestic garbage, long-term accumulation of river bottom silt and harmful substances released from silt. The lack of an environment for aquatic animals and plants makes the water body gradually lose its self-purification ability. In addition, the river sediment has not been cleared for a long time, so that the sediment is continuously released and decomposed into nutrient salts such as N and P, resulting in eutrophication of the water body, and the water body gradually turns green.

Problems solved by technology

However, the existing underwater aerators use an air compressor to suck air into the aerator, push the gas out to achieve water-air mixing, or use a water pump to vacuum inhale air to achieve water-air mixing. Most of them can only aerate on one side or both sides. Air, the aerator cannot rotate freely, the water and air cannot be distributed reasonably, the efficiency is low, and the structure is complex and inflexible
