Description
Technical Field
The invention relates to an aquaculture oxygenation device, and belongs to the technical field of aquaculture devices.
Background
In order to guarantee that aquaculture varieties have sufficient oxygen supply in the growth process, the whole aquaculture process all needs oxygenation, at present, the oxygenation form of an aquaculture pond mainly has two types, firstly, an aerator is arranged on the water surface, and the water surface is stirred to enable oxygen to be dissolved into water and oxygenated through the rotation of an impeller of the aerator. And secondly, an oxygen increasing pipe is arranged under the water surface, and air directly enters the water or the bottom of the pond to increase oxygen in an aeration mode. Both forms of oxygenation are effective, however, the technology is always in progress and both forms of oxygenation also suffer from deficiencies. For example, the oxygen increasing machine is expensive, the oxygen increasing cost is too high, the oxygen increasing on the water surface only can ensure that the water surface has oxygen and the underwater or water bottom does not have oxygen, the oxygen content in the water or the water bottom cannot be increased, the water quality cannot be improved, the culture density cannot be improved, the growth of cultured varieties cannot be accelerated, and the purpose of stable yield and high yield cannot be achieved. Set up the difficult management of oxygenation pipe under water, the oxygenation pipe can only be simple oxygenation, fails to form the laminar flow of the different water layers in aquatic, can not make the hydrologic cycle circulation of pond, and the aquatic oxygen distribution in pond is inhomogeneous, and the water of whole aquaculture pond is static relatively, and organic matter natural decomposition is inhomogeneous, and the place that aquatic oxygen volume lacks can produce toxic gas, is unfavorable for the healthy growth of breed. Therefore, under the prerequisite of these two kinds of forms, seek an oxygenation low cost, can form the oxygenation device of laminar flow in different water layers, to improving the aquatic dissolved oxygen volume of aquaculture pond, form the laminar flow of different water layers for the hydrologic cycle circulation is smooth and easy, and aquatic dissolved oxygen is even, keeps aquaculture water body good quality, and is especially meaningful.
Disclosure of Invention
The invention aims to provide an aquaculture oxygen increasing device which can form laminar flow in water at the bottom of a pond and increase oxygen uniformly so as to overcome the defects of high oxygen increasing cost, nonuniform oxygen increasing and incapability of forming laminar flow of different water layers of the traditional oxygen increasing device.
In order to achieve the purpose, the invention adopts the following technical measures: an aquaculture oxygenation device is a square frame structure and comprises a square frame with six faces, wherein the six faces are the front face of the frame, the rear face of the frame, the left face of the frame, the right face of the frame, the bottom face of the frame and the top face of the frame respectively, air pipes are fixed on four quadrangular frames on the bottom face of the frame, 10-50 nano aeration pipes are connected between the left air pipe and the right air pipe, the distance between every two adjacent nano aeration pipes is 1-2 cm, and an air inlet pipe is arranged on the rear air pipe; the left oblique beam is connected to the diagonal lines between the joint of the front beam and the upper beam on the left side of the rack and the joint of the rear beam and the lower beam, so that the front beam and the lower beam on the left side of the rack form an isosceles triangle with the left oblique beam, a plastic left cover plate is fixed on the isosceles triangle, a right oblique beam and a plastic right cover plate are symmetrically arranged on the right side of the rack, a laminar flow baffle is connected between the left oblique beam and the right oblique beam, and a laminar flow baffle water flow port is reserved at the lower end of the laminar flow baffle.
According to the invention adopting the measures, the fan provides air, the air enters the air pipe from the air inlet pipe and is discharged outwards through the nano aeration pipe connected with the left air pipe and the right air pipe, the discharged air impacts the laminar flow baffle upwards, the airflow direction is changed to move towards the horizontal direction, so that the water flow moves along with the air, different positions where the airflow impacts the laminar flow baffle generate different water flows due to the fact that different aeration pipes discharge the air, and laminar flows in different horizontal directions are formed. The water bottom forced aeration generated by the invention ensures that the water body of the culture pond not only convects from the upper water layer to the lower water layer, but also convects from the front layer, the rear layer, the left layer and the right layer, and moves ammonia nitrogen (NH 3) and nutritive salt which harm cultures in the lower water layer to the upper water layer, thereby helping the propagation of algae, increasing the biomass, strengthening the photosynthesis, increasing the oxygen making capacity of organisms and natural baits; and then the water and algae with high dissolved oxygen thickness in the upper water layer are moved to the lower water layer, so that the dissolved oxygen thickness of the lower water layer is increased, the problem of oxygen debt is solved, the nitrification can be accelerated, and harmful ammonia nitrogen (NH 3) can be nitrified into nontoxic nitrous acid (NO 2) and nitric acid (NO 3), so that the natural bait algae of the cultured substances can be increased. The culture, algae, dissolved oxygen and bottom sediment organic matters, molecular ammonia, nutritive salt and bacteria with cover have ingenious and stable biochemical balance, improve the self-purification capability of the water body, reduce the water change and reduce the risk of cross infection. After the method is adopted for oxygenation, experiments for culturing tilapia are carried out in a culture pond, and the test results are as follows: the method comprises the steps of feeding tilapia mossambica in a 3 mu water surface aquaculture pond, arranging the tilapia mossambica at the bottom of the pond every 15 meters, detecting the dissolved oxygen in water at an irregular period during the aquaculture period, and increasing the dissolved oxygen in water by 25 percent compared with the dissolved oxygen in water in the traditional oxygenation mechanical aquaculture pond with the same aquaculture fish and the same water surface area, increasing the aquaculture survival rate of the tilapia mossambica by 30 percent, and shortening the aquaculture period by 10-15 days.
