Aquaculture oxygenation head and oxygenation device

Abstract

An aquaculture oxygenation head comprises a tubular membrane, an air inlet adapter and a fixing frame, the tubular membrane is in a circular tube shape and comprises a nuclear pore membrane layer anda supporting layer, the nuclear pore membrane layer is composited on the outer side or the inner side and the outer side of the supporting layer in a hot pressing mode, and pore channels for oxygen topass through are distributed in the nuclear pore membrane layer. Wherein the pore channels are uniformly distributed on the nuclear pore membrane layer, the tubular membrane is inserted into the fixing frame, at least one end of the tubular membrane is communicated with the air inlet adapter, the air inlet adapter is arranged on the fixing frame, and the connecting position of the air inlet adapter and the fixing frame is sealed. The tubular membrane based on the nuclear pore membrane is applied to an aquaculture oxygenation head, the oxygenation amount per unit area can be increased, efficient diffusion and transmission of oxygen in a water area can be achieved, and the device is simple in overall structure, small in size and capable of being widely applied to aquaculture of aquatic products; by utilizing the characteristics of uniform pore diameter, same size, high density, high air permeability and the like of the nuclear pore membrane, the releasable and diffusible bubbles are micro-nano bubbles, and the invention has the advantages of large ventilation capacity, low energy consumption, uniform bubble size and the like.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an aeration head and an aeration device for aquaculture. Background technique [0002] At present, the aquaculture industry is gradually showing large-scale and industrialization, and a large number of aquatic organisms have high requirements for the oxygen content of the water body. Therefore, the key to realizing the effect of the emerging farming model in aquaculture is to ensure the oxygen content of the water body. Oxygenation equipment is extremely important for aquaculture, and the oxygenation capacity is an important indicator to measure the performance of aeration equipment. However, in the existing aquaculture oxygenation method, the amount of oxygenation per unit area is insufficient, the oxygenation is uneven, and water quality treatment is difficult. The whole oxygenation device has a complex structure and a large volume, which is not conducive to the...
