Background technique

At present, in the daily management and control of aquaculture ponds, sewage treatment ponds, or aeration ponds, it is often necessary to use some aeration devices to regularly inject air into the water body in the pond to increase the oxygen content in the water body. But how to dissolve air into water quickly, effectively and evenly so as to increase the oxygen content in water has always been a problem studied by many researchers. However, the existing aeration devices are mainly impeller-type or waterwheel-type aerators. The disadvantages of this type of aerators are mainly low oxygenation efficiency, uneven dissolved oxygen in water, and large power consumption.

Whether it is an aquaculture pond, a sewage treatment pond or an aeration pond, the quality of the water in the pond directly affects the growth of animals, plants and microorganisms in the water, thus affecting the ecological balance in the water and human health. At present, the adjustment of water quality is mainly through frequent water changes, frequent sewage discharge, regular flushing of the bottom of the pool, and regular use of drugs by experienced staff to adjust water quality. This method of adjusting water quality not only consumes a large amount of water resources, but also is difficult to control the amount of drugs; if the relevant staff are not sure about the amount of drugs due to certain factors, it may cause the drug residues in the water to exceed the standard, thereby affecting aquatic products. hidden dangers to quality and safety.

Detailed ways

Taking fish ponds as an example, the distributed diffuse atomization oxygenation water quality regulating device designed by the present invention includes a blower (also can use a compressor) 1, an airflow atomizer (also can use an ultrasonic atomizer or a centrifugal atomizer) ) 2, main pipeline valve 3, main pipeline 4, microporous tube 5, temperature control device 6 and ozone generator 7. Wherein the air blower 1 is installed at one end of the loop-type main pipeline 4 with one end closed, and is used for inputting air to the main pipe. The airflow atomizer 2 is installed on the main pipeline 4 and connected to the water source through a pipeline equipped with a valve, so that the airflow atomizer 2 atomizes the water extracted from the water source and mixes it with the air delivered by the blower, thereby A large amount of oxygen dissolves into the atomized water droplets, and the degree of atomization of the water droplets is realized by adjusting the amount of water through the valve on the pipeline connected to the water source. Because the main body part of the main pipeline 4 is placed on the bottom of the fish pond, and is connected on the main body of the main pipe in parallel and equidistantly by several sections of microporous pipes 5, so that several sections of microporous pipes form a uniform distribution at the bottom of the fish pond. network. Open the main pipe valve 3, so that the atomized water diffuses into the water body of the fish pond through the microporous pipe network on the main pipe 4 with the air, and at this time, the dissolved oxygen efficiency of the water body in the fish pond is greatly improved.

When it is necessary to adjust the water quality of the water body in the fish pond, first close the small valve of the pipeline connected to the water source, then open the main pipeline valve 3, put the medicine into the airflow atomizer 2, and the medicine is atomized by the nebulizer The main pipe 4 is evenly sent into each microporous tube 5 forming the microporous tube network, and enters the fish pond water body through the microporous tube 5 to realize uniform regulation of the fish pond water quality.
