Unpowered dissolved oxygen supercharging device for aquatic culture system

Abstract

The invention provides an unpowered dissolved oxygen supercharging device for an aquatic culture system. The unpowered dissolved oxygen supercharging device is used for being placed in a water outlet of a culture tank of aquatic crustacean organisms and comprises a double-layer water drainage pipe and a dissolved oxygen supercharger, the double-layer water drainage pipe comprises an outer pipe and an inner pipe, the inner pipe comprises an upper section pipeline and a lower section pipeline, the upper section pipeline is movably connected with the lower section pipeline, a plurality of water inlet holes are formed in the bottom of the outer side of the outer pipe, the upper edge of the inner pipe is lower than that of the outer pipe, the inner pipe is used for controlling the water level of the culture tank, and the size of the upper section pipeline is the same as that of the lower section pipeline. The unpowered dissolved oxygen supercharging device does not need air supply, does not need an electric aerator or an aerator, is suitable for a recirculating aquaculture mode, especially an indoor factory shallow aquaculture mode, improves the oxygen solubility during aeration, and is simple in structure, safe and convenient to use and good in economical efficiency.

Description

technical field [0001] The invention relates to a dissolved oxygen supercharging device, in particular to a non-powered dissolved oxygen supercharging device used in an aquaculture system. Background technique [0002] Dissolved oxygen is one of the most important and most problem-prone water quality factors in aquaculture. The actual dissolved oxygen in water is subject to the joint influence of biological, physical and chemical factors and changes all the time. When the dissolved oxygen in the water is insufficient, it will firstly have a direct adverse effect on aquatic animals; secondly, it will indirectly affect aquatic animals by affecting other biological and physical and chemical indicators in the water environment, resulting in different degrees of harm to their growth, reproduction and even survival, ranging from physical fitness Decline, growth slowdown, severe head floating, pond flooding, resulting in a large number of deaths.
