Embodiment Construction

[0007] High-purity oxygen or higher-pressure air is provided by the pressure oxygen cylinder 1 (or air pump), etc., and the pressure is adjusted by the pressure-adjustable pressure-regulating valve 2 according to the need, and then the pressure-resistant tube 3 and the self-control check valve 4 are passed into the setting Below the open container 5 with a certain depth below the water surface, the bubbles that emerge are allowed to escape into the container 5. The pressure of the water surface height H'in the container 5 is equal to the pressure of the gas in the container, and it is also equal to H'and the water surface height. The pressure of the difference between H (H-H′) is in accordance with the formula P=ρg(H—H′), ρ (water density) gH (water surface height) is fixed, and the pressure P increases with the decrease of H′. The amount of oxygen also increases. A soft cable or a hard structure can be used below the container 5, and a conical disk 6 with a bottom area and geomet...

Abstract

The invention discloses a pressurized-dissolution type oxygenating apparatus, comprising parts of a pressure gas source, a pressure regulating valve, a gas delivering pipe, an auto-controlled check valve, a float, an open vessel, a conical disk and a drawing rope. The apparatus increases the pressure intensity of a gas in the water to realize the oxygenation by utilizing a physical property that the solubility of the gas in the water rises along with increase of the pressure intensity or(and) decrease of the temperature. In the meantime, compared with existing mechanical and chemical oxygenation, the apparatus has the advantages of high oxygenation efficiency, low purchase and use costs, no noise, no disturbance and harm to fish and shrimp, no pollution, convenient maintenance and being free from power failure and icing.

Description

Technical field [0001] The present invention relates to the field of aquaculture, in particular to the technical field of aquaculture water aeration technology. Background technique [0002] In aquaculture, transportation, and preservation, maintaining sufficient dissolved oxygen in the water body is the basic condition to ensure the survival or growth of fish and shrimp, but most of the existing aerators increase the contact area between water and air under normal pressure. Oxygen is dissolved and diffused into the water to achieve the purpose of aeration, such as the blade lift type, the pump lift type and the bubble type; or the use of chemical agents to generate oxygen, such as peroxides such as hydrogen peroxide. The mechanical oxygenation efficiency is low, the purchase, use and maintenance cost is high, the noise is large, the mechanical parts have high requirements for waterproof and anti-icing, are easy to malfunction, and are easy to disturb and damage fish and shrimp, ...
