Plastic impeller of water wheel aerator

1Product features:

The impeller type aerator is mainly composed of an electric motor, a gearbox, a water surface impeller, and a floating ballPlastic impellerIt is an important component of it, directly related to the contact area between the impeller and the water surface and the oxygenation effect, expanding the concentration gradient of oxygen in water and improving the speed of oxygen transfer and diffusion from the air to the water.

2Product principle:

The oxygenation effect of this equipment is very effective. By using a blade type aerator, a radius centered on the aerator can be formed in the water body10An oxygen rich circle of about meters. In the pond experiment, the impeller aerator was running80About minutes, it can make1.5The dissolved oxygen content and water temperature in the water at a depth of meters are consistent with those in the upper water layer. It can enhance the bottom water and alternate with the surface water, thereby increasing the oxygen content in the lower water layer to a depth exceeding2Rice, suitable for high-yield deep-water fish ponds. The impeller aerator has the functions of stirring water, aerating, mixing, and aerating. These functions are completed simultaneously during the operation of the machine. After booting up,Plastic impellerSuck up the oxygen poor water in its lower part and push it out in all directions to turn stagnant water into living water. The water under the impeller is strongly stirred by the blades and pipes, causing water jumps and waves on the surface of the water, forming a water curtain that can wrap around the air. This not only expands the surface area of the gas-liquid interface, but also thins and continuously updates the double film between the gas and liquid, promoting the dissolution rate of oxygen in the air. During stirring, harmful gases such as hydrogen sulfide, ammonia, methane, sulfur dioxide, etc. that were originally present in the water are also desorbed from the water through aeration and discharged into the air. Due to the rotation of the impellerPlastic impellerThe negative pressure is formed at the rear of the mixing pipe, allowing air to be sucked into the water through the mixing pipe and immediately stirred into microbubbles into the pressure zone of the impeller, which is also beneficial for increasing the dissolution rate of oxygen in the air and improving the efficiency of oxygenation. Due to the continuous lifting and mixing of lower water with surface water, the surface water is constantly renewed, and the surface water is constantly replenished to the lower layer by gravity. The function of the impeller aerator is excellent because it not only helps to break the vertical uniformity of dissolved oxygen in the pool water, but also fully utilizes the biological oxygenation effect.

3Product advantages:

The impeller aerator has the function of emergency oxygenation and is one of the mechanical aerators with a faster oxygenation speed. It can quickly increase the dissolved oxygen in the surrounding water, forming a relatively rich oxygen zone around the aerator. This is also one of the reasons why the impeller aerator can effectively prevent fish from floating.
