What are the types of aerators used for breeding? How much is it? How should I choose?

Aerator is a kind of machine often used in fishery and aquaculture. There are also many types of aerator products, so choose a suitable aerator to obtain good economy. So what are the types of aerators used for breeding? How much is it? How should I choose? Learned from Shandong Machinery Co., Ltd., aerator size and brand are different, the price is not the same, from hundreds to thousands of.

What are the types of aerators used for breeding? How should I choose?

"Water, species, bait and pipe" are the "four elements" of aquaculture, and the correct use of pond aerator involves two important indexes of pond water quality and culture management. in the actual culture production, if the aerator can be used correctly and skillfully, the aquaculture production can get twice the result with half the effort.

1. Impeller aerator

This kind of aerator uses the principle of stirring water and aeration to increase the amount of dissolved oxygen in water, which has good oxygen-increasing effect, high power efficiency, large service area, but high noise. When working, the impeller rotates, stirs the water body, makes the water layer convection up and down, sends the surface oxygen-rich water to the bottom, and lifts the bottom water upward. The water depth of the pool is required to be 1.5 × 2m. This kind of aerator is divided into many types according to the power of the motor.

2. Water truck aerator

When this kind of aerator is working, the blade hits the water at high speed and stirs the air into the water to achieve the purpose of increasing oxygen. The utility model has the advantages of good dynamic effect, strong push mixing effect, and will not stir the sediment, but it is noisy, easy to form water fog and high mechanical failure rate. Its oxygenation power efficiency is 180g/kw.h. This kind of aeration machine is suitable for culture in shallow ponds and large water surfaces.

3. Jet aerator

This kind of aerator is composed of a submersible pump and a jet tube. When working, the water in the pump is ejected at high speed from the nozzle in the jet tube, resulting in negative pressure, inhaling air, water and gas are mixed in the mixing chamber, and then pressed out by the diffusion tube, and the dissolved oxygen will spread along with the flow in a straight line. The utility model has the advantages of good oxygen-increasing effect, no noise and high dissolved oxygen content, but the service surface is not large. Its aerobic power efficiency is 380~1420g/kW.h, which is suitable for high-density culture and deep-water fish pond culture.

4. Inflatable aerator

The main engine of this kind of aerator is air compressor or blower. Pressurized air is discharged through sand filter elements or microporous plastic pipes installed at the bottom to form tiny bubbles, and part of the oxygen is dissolved into the water in the process of bubble rising. The machine has strong oxygen-increasing ability and remarkable power saving. Its aerobic power efficiency is 230g/kW.h, which is suitable for deep water and large area fish ponds.

5. Water jet aerator

This kind of aerator uses a water pump to send water into the sprinkler installed in the middle and shore of the fish pond, so that the water ejects and falls in rain, so as to come into contact with the air to increase the concentration of dissolved oxygen in the water. Its aerobic power efficiency is 130~220g/kW.h, which is only suitable for small fish ponds with shallow water.

6. Oxygen-activated aerator

This kind of aerator not only has a good effect on increasing oxygen to sewage, but also can shoot sewage into deeper and farther service waters in the form of convection, so that there is no dead point in the whole sewage tank. This model can be bought in places with serious pollution.

There are many other types of aerators, such as oil-free permanent magnet DC aerator, dissolved oxygen automatic aerator and so on. In short, when selecting and purchasing aerators, we should pay attention to the product model and quality, second, consider the efficiency of increasing oxygen, and third, according to the needs of production, choose two kinds of aerators to be used together to achieve twice the result with half the effort. Such as the current general pond fish culture mostly choose impeller type culture machine, edible fish breeding pond can choose to buy 1.5~3.6kW, fish pond or overwintering pond can choose 0.37~0.55kW.
