Aerator

Abstract

The invention relates to the technical field of aquaculture equipment, and particularly relates to an aerator. The aerator comprises a motor and a pump head, wherein the outer casing of the motor is fixed to the pump head by fasteners; one side of the pump head is provided with an air inlet; the air inlet is connected with an air inlet pipe; a containing cavity is arranged in the pump head; the containing cavity is provided with a connecting member; a rotating shaft of the motor passes through the middle of the pump head and is fixedly connected with the connecting member; an air guide hole isformed in the connecting member; an air outlet pipe communicates with the lower end of the connecting member; the containing cavity communicates with the air outlet pipe through the air guide hole; an impeller is fixedly connected to one end of the air outlet pipe; and a plurality of air outlet holes are formed in the impeller. According to the aerator, ozone is led out from the air outlet holesformed in the circumferential side of the impeller, a larger diffusion range is achieved, dissolved oxygen in the water can be increased while the river water is disinfected, the water quality is improved, primary productivity in the water body is increased, the occurrence of diseases in the benthic culture species in ponds is reduced, and the survival rate is increased, thereby increasing production.

Description

technical field [0001] The invention relates to the technical field of aquaculture equipment, in particular to an aerator. Background technique [0002] Ozone is a natural substance that has long existed on the earth, but it was more than a hundred years ago that humans really knew about ozone. In 1868, European scientists obtained the first patent for ozone application technology, and scientists found an efficient and economical method (using air as The method of high-voltage discharge of raw materials) uses a high-voltage alternating current between two electrodes separated by a layer of dielectric, and generates high-frequency discharge under the action of a high-voltage electric field. When oxygen or air passes through these discharge spaces, a part of oxygen molecules are activated and decomposed into Oxygen atoms, and then the oxygen atoms combine with oxygen molecules to generate ozone. Since then, ozone has been used as a fungicide test for large-scale water treatmen...

AI Technical Summary

Problems solved by technology

[0004] At present, there are a lot of ozone equipment for pond fish farming on the market, all of which are installed on the bank of the fish pond. A hose for transporting ozone gas is introduced into the water of the fish pond. When the hose is used to release ozone gas in the water, only some bubbles can be blown. Bubbles, the dissolved ozone water has a small diffusion range, and the effect is not ideal
