Problems solved by technology

[0004] 1. The existing oxygen supply device for aquaculture needs to be fixed by aligning the fixing holes when connecting the connection block and the support frame of the oxygen supply device during use, which is time-consuming and prone to loosening during long-term use, resulting in an unstable connection
[0005] 2. The existing aquaculture oxygen supply device has a fixed structure when the buoy is connected, so it cannot be connected according to the size of the buoy. The limitation is relatively large, and the connection is unstable and relatively loose.
[0006] 3. The existing oxygen supply device for aquaculture is highly corrosive because the buoy is exposed to the air for a long time during use, and it is easy to cause cracks on the surface of the buoy, resulting in damage and increasing the cost of replacement

Embodiment 1

[0028] Such as 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 aqua...

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 vanillyl nonanoic acid, 6-8 parts of zinc pyrithione, 0.02-0.05 parts of 1-methyl-trans-1,2-cyclopropanedicarboxylate, 0.02-0.05 parts of anti-algae agent .5-1.5 parts, 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, processability, wet...

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, which belongs to the technical field of aquaculture, and comprises a breeding box. The top of the breeding box is provided with an inwardly recessed chute, and the inside of the chute is movably connected to a water collection tank. There are several mesh holes, an oxygen increasing device is installed on the upper surface of the partition, an air compressor and a circulation pump are respectively arranged on the left and right sides of the breeding box, and the air compressor and the circulation pump are located above the supporting frame. The device supplies oxygen in layers to meet the oxygen demands of different aquatic products, can increase the oxygen concentration in the aquaculture water, and can also filter impurities in the water, so that the aquaculture water can be recycled.

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...
