Blade, aeration combined typed bleeding machine

Abstract

This invention discloses a combined oxygen-increasing machine for aquaculture. In this machine, a motor is used to drive a high-pressure air machine, whose air outlet pipe is connected with a gas-storage bag. Air-bleeding pipes distributed on the air-storage bag are extended into a water body of a certain depth, and microporous air-exhaust pipes are connected with the ends of the air-bleeding pipes. The main axis of the high-pressure air machine is decelerated through a planet gear decelerator and an umbrella gear decelerator, and the output axis drives the slurry impeller. All the parts are installed on a frame, which is fixed with the buoy below so that the frame is floating on the water. The machine can increase the oxygen content in the water by the microporous air-exhaust pipes, and has such advantages as simple structure, few parts.

Description

Technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aeration device for aquaculture water. Background technique [0002] The aerators currently in use include impeller type, waterwheel type, water spray type, water pump type, air pump type and other types of aerators. Among them, impeller type, waterwheel type and water spray type aerators are used to disturb the surface. Water increases the amount of dissolved oxygen on the surface of the water, and it is difficult to improve the amount of dissolved oxygen in the water with a certain depth; the pump aerator can disturb the water with a certain depth and mix with the inhaled air to achieve the purpose of aeration, but the pump outlet The jet of water often has a higher pressure, which can cause damage to small fish and shrimps. The air pump aerator can overcome the above-mentioned defects. For example, the imported Roots blower aerator is installed on the shore to remove the air...

Problems solved by technology

[0002] The aerators currently in use include various types of aerators such as impeller type, waterwheel type, water spray type, water pump type, and air pump type. It is difficult to improve the dissolved oxygen in water with a certain depth; the water pump aerator can disturb the water with a certain depth and mix with the inhaled air to achieve the purpose of increasing oxygen, but the water pump outlet The sprayed water flow often has a high pressure, causing damage to small fish and shrimp; the air pump type aerator can overcome the above defects, such as the imported Roots blower aeration device, which is installed on the shore. Pipes are pre-laid in water bodies such as ponds and pools for breeding, and inflated to a certain depth of water to achieve the purpose of increasing oxygen; but the cost of this device is very expensive, especially the cost of laying pipes is much more expensive than the unit price, and it is difficult for farmers to bear , cannot be popularized; in order to solve the above problems, the applicant once invented a combined aerator with swirling flow and inflation, publication number: CN1505250, which not only has the impeller to disturb the water body to form a swirling flow, but also passes the high-pressure air pump Discharge micro-bubbles into the water body to increase the contact area between water and air to achieve the purpose of oxygenation; practice has proved that this kind of aerator has a better oxygenation effect on the water body, especially suitable for fish farming, but for shrimp farming Because of the high-speed rotation of the impeller under water, the shrimps are often damaged, so this kind of aerator is not very suitable for farming shrimps.
