Abstract

The invention provides an aquaculture oxygen charging system. The aquaculture oxygen charging system is characterized by comprising an oxygen supply device, a Venturi mixer, a water distribution device and a submerged pump, wherein the oxygen supply device comprises any one or both of an air compressor and a liquid oxygen tank; the Venturi mixer is provided with a water inlet, a water outlet and an air inlet; the air inlet is communicated with the oxygen supply device by virtue of an air supply pipeline, a one-way valve is arranged on the air supply pipeline, and the one-way valve is used for controlling the oxygen supply deice to supply air to the Venturi mixer; the water distribution device comprises a water outlet main pipe which is communicated with the water outlet and a plurality of water outlet branch pipes which are communicated with the water outlet main pipe; each water outlet branch pipe is provided with a plurality of water distribution fine holes; the submerged pump is communicated with the water inlet by virtue of a water conveying pipeline, and is used for transferring a water body in a pond into the Venturi mixer by virtue of the water conveying pipeline and the water inlet; a check valve is arranged on the water conveying pipeline. The aquaculture oxygen charging system provided by the invention is high in effluent dissolved oxygen content and low in energy consumption.

Description

technical field [0001] The invention belongs to the field of fishery and mass transfer, and in particular relates to an aquaculture oxygenation system. Background technique [0002] With the vigorous development of aquaculture, the contradiction between extensive pond cultivation and high-density cultivation needs is becoming more and more prominent. In summer, due to the high temperature, the water body is often hypoxic, causing a large number of aquatic products such as fish and shrimp to die due to hypoxia. Therefore, it is necessary to supply additional oxygen to the water body to meet the needs of aquaculture. [0003] Existing devices for supplying oxygen to ponds mainly include impeller-type surface aerators. Due to the limited aeration depth and aeration area of ​​the impeller surface aerator, the aeration efficiency is low and the amount of dissolved oxygen is small. Contents of the invention [0004] The purpose of the present invention is to provide an aquacul...
