Aerator

Abstract

The invention discloses an aerator. A motor is fixedly mounted on a support in a radial shape or a disk shape. The edge of the support is provided with multiple driven gears which are connected with impellers. A motor shaft of the motor is connected with a driving gear. The driving gear and the driven gears are connected in a meshing mode. A float bowl is arranged on the support or the driving gear. The driving gear is further provided with auxiliary blades. According to the aerator, by the adoption of the structure, the mixing contact area between the air and a water body is enlarged under the interaction between small blades of the impellers and water, and then the amount of dissolved oxygen of the water body is increased; compared with a single-impeller structure in the prior art, the oxygen dissolving efficiency is improved under the same energy consumption. Preferably, the rotating direction of the arranged auxiliary blades is opposite to the torque in the revolution direction of the impellers, so that the torque generated by the auxiliary blades and the torque generated by the impellers are basically equal, both the auxiliary blades and the impellers achieve the aeration effect, and particularly a fixing frame used for fixing the whole device does not need to be arranged additionally.

Description

technical field [0001] The invention relates to the field of breeding equipment, in particular to an aeration machine suitable for use. Background technique [0002] Along with the rapid development of fish farming, many places have successively built a large number of ponds for fish farming. In the hot summer, the temperature is high, resulting in an extremely low dissolved oxygen in the water body, which is not conducive to the healthy growth of fish, and what is more often leads to the death of a large number of fish, causing huge economic losses. The existing fish pond aerator, The water is raised by an impeller to increase the contact area with the air, thereby increasing the dissolved oxygen in the water. But this device is only the structure that is fixed in one place, and it is relatively troublesome to arrange the fixing frame. It is also not suitable for larger water surface aquaculture occasions. Moreover, the energy consumption is high, and the efficiency is l...

In the hot summer, the temperature is high, resulting in an extremely low dissolved oxygen in the water body, which is not conducive to the healthy growth of fish, and what is more often leads to the death of a large number of fish, causing huge economic losses. The existing fish pond aerator, The water is raised by an impeller to increase the contact area with the air, thereby increasing the dissolved oxygen in the water

However, this device is only a structure fixed in one place, and it is troublesome to set the fixing frame

Not suitable for larger water surface farming occasions

Moreover, the energy consumption is high, and the efficiency is low in terms of oxygenation effect
