Archimedean spiral oxygen increasing device enabling bottom water of fish pond to be used circularly

Abstract

The invention discloses an archimedean spiral oxygen increasing device enabling bottom water of a fish pond to be used circularly. The archimedean spiral oxygen increasing device comprises an archimedean screw pump obliquely installed in water, a water throwing device with the top cut off and an annular water container located above the water throwing device, wherein the water throwing device with the top cut off is located on a water surface and in a circular cone column shape, a water outlet of the archimedean screw pump is connected with the annular water container, and dripping holes are evenly formed in the bottom of the annular water container; a double-shaft output motor is mounted above the water throwing device, a lower output shaft of the double-shaft output motor is connected with the water throwing device, and an upper output shaft of the double-shaft output motor is in transmission connection with a screw shaft of the archimedean screw pump through a cylindrical gear and a bevel gear wheel. Bottom water is pumped to the water surface through the archimedean screw pump, rotates at a high speed through the water throwing device and is thrown to air through the water throwing device. Thus, flowing and updating of the bottom water of the fish pond can be promoted, and oxygenolysis and volatilization of hazardous substances such as sulfide, nitrite and ammonia nitrogen are greatly quickened.

Description

technical field [0001] The invention relates to an aeration device, in particular to an Archimedes spiral aeration device for recycling fish pond bottom water. Background technique [0002] The aerator is a machine often used in the aquaculture industry. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be hypoxic. At the same time, it can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pool water from threatening the living environment of the fish. The current fish pond oxygenation generally adopts water surface mechanical oxygenation, but the oxygenation effect of traditional water surface mechanical oxygenation is only about 50 cm deep, and the bottom water always has less dissolved oxygen, which is not conducive to the harmful organic matter and nitrite deposited at the bottom of the water body. The oxidative decomposition of substances leads to the enrichment of...

Problems solved by technology

The current fish pond oxygenation generally adopts water surface mechanical oxygenation, but the oxygenation effect of traditional water surface mechanical oxygenation is only about 50 cm deep, and the bottom water always has less dissolved oxygen, which is not conducive to the harmful organic matter and nitrite deposited at the bottom of the water body. Oxidation and decomposition of substances lead to the enrichment of harmful substances such as sulfide, nitrite, and ammonia nitrogen in the bottom water

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
