Problems solved by technology

[0004] 1. When the existing oxygen supply device for aquaculture is used to connect the connection block and the support frame of the oxygen supply device, it is necessary to align the fixing holes for fixing, which takes time and is prone to loosening during long-term use, resulting in an unstable connection
[0005] 2. The existing oxygen supply device for aquaculture has a fixed structure when the buoy is connect

Embodiment 1

[0028] like Figure 1-6 As shown, the oxygen supply device for aquaculture comprises a culture box 1, and the top of the culture box 1 is provided with an inwardly recessed chute 2, which is movably connected to the sump 3 in the chute 2, and the inside of the culture box 1 is provided with a partition 18, a partition The surface of 18 is provided with several mesh holes, the upper surface of the dividing plate 18 is equipped with an oxygen increasing device 22, and the left and right sides of the culture box 1 are respectively provided with an air compressor 16 and a circulation pump 10, and the air compressor 16 and the circulation pump 10 are located on the supporting frame. 11 above. The aquaculture box is divided into upper and lower layers by a partition to meet the different needs of aquaculture for dissolved oxygen and ensure the survival rate of aquaculture. The air compressor and circulation pump work at the same time to circulate the aquaculture water in the aquacul...

Embodiment 2

[0038] The surface of the impeller 221 is coated with an antifouling coating, which is composed of the following components and parts by weight: 45-50 parts of zinc acrylate resin, 15-20 parts of diisononyl phthalate, 1-5 parts of nano-silver powder 7-15 parts of nonanoic acid vanillyl amide, 6-8 parts of zinc pyrithione, 0.02-0.05 parts of 1-methyl-trans-1,2-cyclopropanedicarboxylate 0.02-0.05 parts, 0.5-1.5 parts of anti-algae agent 10-35 parts of zinc oxide, 10-15 parts of wetting and dispersing agent, 20-25 parts of anti-settling agent, 13-15 parts of talcum powder and 6-8 parts of organic solvent. The addition of 1-methyl-trans-1,2-cyclopropanedicarboxylate in the coating can significantly increase the activity of each component, effectively broaden the molecular weight distribution of the polymerization product, reduce the viscosity of the polymerization reaction glue, and make the polymer Generate a branched structure, improve the cold flow of the polymer, processabilit...

Embodiment 3

[0041] In the actual use process of the aquaculture oxygen supply device of the present invention: the aquatic products that need to be cultured are cultured in layers, the air compressor 16 and the circulation pump 10 work at the same time, so that the culture water in the culture tank 1 can be circulated, and the circulation pump 10 can Water is sucked in the suction pipe 12, and the cultured water passes through the filter box 9, which filters the deep layer of the cultured water, and then sends the water collection tank 3 to be discharged to the cultured box 1, and the air compressor 16 will introduce a large amount of gas into the oxygen supply pipe 17, A plurality of aeration valves 14 on the surface of the oxygen supply pipe will eject the gas, which effectively increases the oxygen capacity in the water. The impeller 221 of the oxygen increasing device 22 above the partition 18 continuously stirs the water to make the water and air The contact of the area will eventuall...

Abstract

The invention discloses an oxygen supply device for aquaculture, and belongs to the technical field of aquaculture. The oxygen supply device comprises a culture tank. The top of the culture tank is provided with an inwardly recessed sliding chute. A water collecting tank is movably connected in the sliding chute. A separator plate is disposed in the culture tank. The surface of the separator plateis provided with a plurality of meshes. An oxygenation device is installed on the upper surface of the separator plate. An air compressor and a circulating pump are respectively disposed at left andright sides of the culture tank and located on supporting frames. Layered oxygen supply is achieved, oxygen requirements of different aquatic products are satisfied, oxygen concentration in culture water can be increased, and impurities in the water can also be filtered to recycle the culture water.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an oxygen supply device for aquaculture. Background technique [0002] my country is a big country in the world for aquaculture. The area of ​​pond aquaculture alone reaches about 20 million mu, and the aquaculture output ranks first in the world. Recently, with the continuous expansion of aquaculture area and breeding density in our country, the weather conditions are getting worse and worse, and the requirements for dissolved oxygen of aquatic products are getting higher and higher. Low dissolved oxygen makes it breathe faster, and if it is lower, it will float or even die. Under normal circumstances, the lack of oxygen in fish ponds is often at night, especially when the air pressure is low at dawn, and the dissolved oxygen is the lowest. Farmers stick to it all night to observe fish schools. [0003] There are still some deficiencies in existing oxygen supply...
