Sinking fall water-flowing comprehensive oxygenation and purification device

Abstract

The invention discloses a sinking fall water-flowing comprehensive oxygenation and purification device which comprises a water leading pipe inserted into the bottom of a fishpond and a sinking device connected with the water leading pipe. A water outlet of the water leading pipe is lower than a water inlet of the water leading pipe, a filtering device is arranged on the upper portion of the sinking device, a water storage chamber is formed in the lower portion of the filtering device and communicated with a water outlet pipe, and a water pump is installed on the water outlet pipe. The sinking fall water-flowing comprehensive oxygenation and purification device further comprises a canal used for conveying water in the water storage chamber back to the fishpond. The canal is connected with the water outlet pipe. According to the sinking fall water-flowing comprehensive oxygenation and purification device, the siphon principle is used, so that self water flowing of the fishpond is achieved, and electrical energy is saved. Due to the filtering device arranged on the sinking device, the water-air contact area can be enlarged, the oxygen dissolving effect can be improved, and impurities such as ammonia nitrogen and nitrite in water can be filtered and adsorbed. The water filtered and purified by the sinking device flows back to the fishpond through the canal and a backflow pipe so that water flowing oxygenation can be achieved in the canal conveying process.

Description

technical field [0001] The invention relates to an oxygen increasing device, in particular to a comprehensive oxygen increasing and purifying device for sinking head and flowing 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 l...

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
