Oxygen conveying device and method for aquaculture

Abstract

The invention discloses an oxygen conveying device and method for aquaculture, and belongs to the technical field of oxygen conveying devices for aquaculture. The oxygen conveying method for aquaculture includes the specific steps that step one, a protective base is placed into a culture pond; step two, an aerator and a driving mechanism are started to drive a rotating shaft to rotate; step three, a cleaning mechanism is simultaneously driven to clean a water flowing hole; and step four, the rotating shaft drives vortex blades to drive a water body to circulate, and a vortex oxygenation pipe is used for oxygenating the flowing water body. According to the oxygen conveying device and method for aquaculture, when the culture pond is aerated, the rotating shaft is used for driving the vortex blades to drive the water in the whole culture pond to flow, so that the whole culture pond can be aerated gently without moving the oxygen conveying device, the aeration speed is increased, and the normal growth of cultured objects in the culture pond is prevented from being interfered; and the vortex oxygenation pipe continuously outputs oxygen and is in stirring contact with the flowing water, so that the oxygenation efficiency of the water is improved.

Description

technical field [0001] The invention relates to the technical field of oxygen delivery equipment for aquaculture, in particular to an oxygen delivery equipment and method for aquaculture. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. Aquatic animals and plants need oxygen in breeding. When the solubility of oxygen in water is less than 2mg / L, the water will stink; generally, when the dissolved oxygen in water is less than 5mg / L, organisms cannot survive. However, the density of aquaculture is generally higher than the density of natural growth, resulting in the oxygen in the water body usually cannot meet the needs of such high-density fish, so artificial aquaculture ponds must regularly supply oxygen to the aquaculture ponds to ensure the fish's...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of oxygen delivery equipment and method for aquaculture, to solve the above-mentioned background technology proposed in the prior art when utilizing oxygen delivery equipment to carry out oxygen delivery to aquaculture pond, oxygen delivery device needs to be used for the pond water in the aquaculture pond Pumping into the oxygen delivery equipment for oxygenation, the location of the pumped water is relatively concentrated and the volume is large, the pumped pool water may cause the pool water to fluctuate greatly, but the ability of mixing and contacting oxygen and water is limited. On the other hand, it cannot be quickly and fully The comprehensive oxygen supply in the aquaculture will easily lead to the problem of insufficient oxygen concentration in the water body
