Microporous aeration oxygen-increasing device

Abstract

The invention relates to a microporous aeration oxygen-increasing device which comprises a blower, an air conveying tube and an oxygen-increasing disc, wherein the air conveying tube is connected with an air outlet of the blower; the oxygen-increasing disc is formed by an oxygen-increasing tube which is spirally wound and is gradually lifted from the center to the periphery so as to form a discoid shape; two ends of the oxygen-increasing tube are mutually connected through a connecting tube; a joint tube is arranged at the center of the oxygen-increasing disc along a winding axis of the oxygen-increasing tube; two ends of the joint tube are respectively connected with the connecting tube and the air conveying tube; an impeller is arranged on the joint tube and the outer wall of the joint tube is sleeved with the impeller through a bearing; an included angle of 10 DEG to 30 DEG is formed between the axial direction of the impeller and the joint tube; the oxygen-increasing tube is formed by an inner tube and a ventilated sponge layer which is wrapped on the outer surface of the inner pipe; and air vents passing through the tube wall are distributed in the tube wall of the inner tube. Thus, the problem that the air cannot smoothly flow out of the air vents at the lower part due to the reason that the oxygen-increasing disc is sunken into the bottom of water is avoided; and the impulse force of the oxygen-increasing disc, prompting the oxygen-increasing disc to move, is obtained. Therefore, the activity area of the oxygen-increasing disc in the water is enlarged, namely, the oxygen-increasing effect is further improved.

Description

technical field [0001] The invention relates to a water body oxygenation device, in particular to a microporous aeration oxygenation device. Background technique [0002] At present, there are two main methods to increase the dissolved oxygen in water: aeration and oxygenation and oxygenation, among which aeration is the main method. Aeration and oxygenation can be divided into blast aeration and mechanical aeration. Mechanical aeration is the impeller, water wheel, jet, etc., by stirring the water, causing the interface contact between water and gas, which can only solve the oxygenation of the upper water body, and the gas-liquid contact interface is intermittent, the contact area is small, and the contact time is short. In terms of noise, the mechanical aerator is placed directly on the water, and the sound of beating the water is very loud, which affects the normal growth of aquatic organisms. Blast aeration is to pass the air delivered by the fan into the bottom of...

Problems solved by technology

However, the current design of the microporous aeration device is not perfect, the distribution of air bubbles is uneven, and the effect of oxygenation needs to be further improved.
