Problems solved by technology

This method of oxygenation needs to overcome gravity to do work, consumes a lot of power, and has a lot of noise. When the water body is thermally stratified in summer, it is ineffective for the colder water in the middle and lower parts of the pond, resulting in stagnant water in the middle and lower parts of the pond, producing harmful substances such as hydrogen sulfide, and breeding pathogens, causing a large number of fish in the pond to die; oxygenation type, microporous oxygenation, etc., are to inflate the aerated zeolite or porous tube in the pond, and the bubbles will contact the water body during the upward growth process to achieve the purpose of increasing oxygen. The oxygen mode is limited by the setting depth. As the depth of the water body increases, the less air bubbles are generated, and the contact distance between the air and the water body is limited. It is difficult to install in the pond, and it will also bring difficulties to pulling the net and cleaning the pond. For large ponds The laying device is particularly difficult

Embodiment 1

[0019] The aeration device of the present invention is arranged in the pond, adjust the buoyancy tank 5, make the three-way tube 8 be under the horizontal plane, adjust the depth of the water inlet 9 at 1 / 3 of the depth of the pond, and fix the position of the aeration device. Turn on the motor 1, connect the trachea 4, and the oxygen increasing device works. At 3:00 a.m. in August, fish in the 5-acre tilapia pond began to float. Turn on the motor 1, connect the trachea 4, and the aeration device worked. After 2 hours, the fish floating head disappeared and the dissolved oxygen in the pond reached 6 mg / L.

Embodiment 2

[0021] The aeration device of the present invention is arranged in the pond, adjust the buoyancy tank 5, make the three-way cylinder 8 be under the horizontal plane, adjust the depth of the water inlet 9 at 2 / 3 of the depth of the pond, and fix the position of the aeration device. Turn on the motor 1, connect the trachea 4, and the oxygen increasing device works. At 12:00 noon on a sunny day in August, oxygenation was added to the 10-acre tilapia pond. The motor 1 was turned on, the air pipe 4 was connected, and the oxygenation device was working. After 3 hours of starting up, the water in the entire pond became a living body, and the upper and lower water bodies in the pond were mixed evenly. , The dissolved oxygen at the bottom of the pond reaches 8 mg / L to improve the water quality. The survival rate of fish in the pond has increased significantly this year.

Abstract

The invention discloses an oxygenation device for ponds. The oxygenation device is characterized by comprising a T-shaped triple cylinder, a porous propeller, a collecting cover and a buoyancy tank. The porous propeller is driven by a motor and perpendicularly arranged in a perpendicular passage of the triple cylinder, and blades of the porous propeller are provided with air holes communicated with the hollow cavity. The collecting cover is arranged on the lower portion of the porous propeller, an opening of the collecting cover is communicated with a hollow cavity of the porous propeller, a vent pipe is connected in the collecting cover, and the buoyancy tank is arranged on the triple cylinder. The oxygenation device does not act on gravity of water body and overcomes water viscous force to form power to drive the water body to horizontally flow. The oxygenation device has the advantages of fast oxygenation, effectiveness in oxygenation and water stirring, capability of reducing diseases of fish, small size, convenience in operation and the like.

Description

technical field [0001] The invention belongs to the technique of aerating and increasing oxygen in pond water body. In particular, it relates to a pond aeration device capable of fully stirring and mixing air and water without leaving a depth blind spot, thereby forming a living body space where the pond water flows. Background technique [0002] At present, there are generally impeller type, waterwheel type, water spray type, jet type, oxygenation type, microporous aeration type, etc. for pond water body oxygenation. The impeller type, water wheel type, water spray type, jet type, etc. are mechanical devices driven by motors, which throw water into the air, disperse it, and fully contact with the air to achieve the purpose of increasing oxygen. This method of oxygenation needs to overcome gravity to do work, consumes a lot of power, and has a lot of noise. When the water body is thermally stratified in summer, it is ineffective for the colder water in the middle and lower ...
