In the figure: 1-a culture pond, 2-a tank body, 21-a water outlet, 3-a liquid level in the tank body, 4-a liquid level in the culture pond, 5-an oxygen return pipe, 6-a connecting part, 7-an air inlet pipe, 8-a one-way valve and 9-a water inlet pipe.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in figure 1, the utility model relates to an oxygenation device for aquaculture, including a jar body 2, adapting unit 6 and inlet tube 9 are passed through to the upper portion of jar body 2, install intake pipe 7 on this adapting unit 6, install oxygen back flow 5 on jar body 2, the one end of this oxygen back flow 5 is connected with the upper portion of jar body 2, and the other end is connected with adapting unit 6, the lower part processing of jar body 2 has outlet 21. When using, will be used for aquaculture's oxygenation device to install in cylindrical breed pond 1, the installation direction of outlet 21 is unanimous with the tangential direction of cylindrical breed pond 1, and outlet 21 is located the below of breeding pond liquid level 4, because outlet 21 is located the lower part of the 2 lateral walls of jar body, and the dissolved oxygen water that flows out from outlet 21 makes the water rotation of breeding in the pond 1, is favorable to dissolved oxygen water evenly distributed in breeding pond 1. The one end and the adapting unit 6 of intake pipe 7 are connected, the other end is connected with external oxygen making equipment, the pure oxygen of intake pipe 7 and the water of flowing through inlet tube 9 contact in adapting unit 6 inner, and dissolve fast, undissolved oxygen is suspended in the aquatic with very little bubble, and dissolve gradually, the area of contact of oxygen and water is big, can the oxygen suppliment in succession, dissolved oxygen is fast, dissolved oxygen is big, the adjusting tank body 2 and the relative height of breeding pond liquid level 4, can adjust the dissolved oxygen degree of depth, oxygenation is effectual. Oxygen which is not dissolved in the water gradually floats upwards and is gathered at the upper part of the tank body 2, and when the gathered oxygen is enough, the oxygen enters the connecting part 6 through the oxygen backflow pipe 5 and is mixed with the water again, so that the oxygen is fully utilized.
The drain opening 21 is located at a lower portion of the sidewall of the can body 2. Avoiding the oxygen bubbles from being brought out of the tank body 2, and conveniently improving the dissolved oxygen depth of the water body in the culture pond 1.
The length of the water outlet 21 is not less than the radius of the tank 2, and the width of the water outlet 21 is not less than 1/10 of the height of the tank 2. So that the dissolved oxygen water flowing out of the water outlet 21 can stir the water body in the culture pond 1, and the dissolved oxygen water is conveniently and uniformly distributed in the culture pond 1.
And the air inlet pipe 7 is provided with a one-way valve 8. Prevent gas or water from flowing back and damaging the oxygen generating equipment.
The tank body 2 is made of PVC or PP materials. The weight of the tank body 2 is reduced, the transportation, the maintenance and the disassembly and assembly are convenient, and the manufacturing cost of the tank body 2 is greatly reduced.
The oxygen return pipe 5, the connecting part 6, the air inlet pipe 7 and the water inlet pipe 9 are all made of PVC or PP materials. Further reduce the weight of whole oxygenation device, convenient transportation, maintenance and dismouting have reduced oxygenation device's manufacturing cost simultaneously.
A oxygenation device for aquaculture, its theory of operation as follows:
the water flowing through the water inlet pipe 9 and the oxygen flowing through the air inlet pipe 7 are mixed in the connecting part 6 and then enter the water at the lower part of the tank body 2, part of the oxygen is suspended in the water in tiny bubbles and gradually dissolved, and the high-dissolved oxygen water enters the culture pond 1 from the water outlet 21 at the lower part of the tank body 2; the undissolved oxygen floats upwards gradually and is collected at the upper part of the tank body 2, and when the collected oxygen is enough, the oxygen enters the connecting part 6 through the oxygen backflow pipe 5 and is mixed with water again; when the oxygen introduction amount is large, the dissolved oxygen of the water body in the tank body 2 is saturated, the pressure on the upper part of the tank body 2 is increased, the liquid level 3 in the tank body is lower than the liquid level 4 of the culture pond, and the dissolved oxygen level of the water body is further improved by the increase of the pressure, so that the higher dissolved oxygen requirement is met.
In the utility model, the size of the water inlet pipe 9 and the water inlet pressure have no fixed requirements, no additional water pump is needed, and the energy consumption is low; the pressure in the tank body 2 is balanced with the pressure in the culture pond 1, so that the phenomenon that over-saturated dissolved oxygen water is formed to harm organisms in the culture pond 1 is avoided; the water outlet 21 can also be arranged at the bottom of the tank body 2 and is externally connected with an elbow to change the water discharging direction.
