A pressurized fine-hole water spray oxygenation device using the bottom water body of fish ponds

Abstract

The invention discloses a device for oxygenation by pressurizing bottom water in pond and spraying the water through small holes. The device comprises a container tank. A main water inlet pipe is connected to the bottom of the container tank and leads to the water bottom, and the main water inlet pipe is connected with a plurality of water inlet branch pipes scattered all around at the water bottom. The container tank is connected with an air inlet pipe, and the air inlet pipe is connected with an air compressor. The container tank is connected with a plurality of water outlet branch pipes, and the water outlet branch pipes are erected above the water surface of the pond. The device further comprises a single-chip microcomputer system, and the single-chip microcomputer system is connected with the air compressor. Through the device, on the one hand, vertical circular flow of water in the pond can be accelerated; on the other hand, compressed air is injected into oxygen-deficient water in the container tank through the air compressor, the oxygen content of water is increased, then the water is sprayed out of the small holes of the water outlet branch pipes, the area of contact between water and air can be further enlarged due to formed water mist, and thus the oxygenation effect can be greatly improved.

Description

technical field [0001] The invention relates to an aeration device, in particular to a pressurized fine-hole water spray aeration device using the bottom water body of a fish pond. Background technique [0002] The aerator is a kind of machine that is often used in aquaculture, and the impeller aerator is the most widely used in recent years. The impeller type aerator floats on the water surface through the buoyancy of multiple floating balls. The impeller only rotates on the water surface, and only a small amount of air is stirred into the water. The oxygenation effect is only about 50 cm deep, and the bottom water always dissolves oxygen. Less, it is not conducive to the oxidation and decomposition of organic matter and nitrite and other harmful substances deposited at the bottom of the water body, resulting in the enrichment of sulfide, nitrite, ammonia nitrogen and other harmful substances in the bottom water. For this reason, my country's aquatic industry is vigorously...

AI Technical Summary

Problems solved by technology

For this reason, my country's aquatic industry is vigorously advocating and promoting underwater aeration and oxygenation technology to achieve effective bottom oxygenation. Oxygen time is short, water body flow is less, so the range of water body for effective aeration and oxygenation is small, which leads to unsatisfactory promotion effect of this technology
