This breed drainage oxygenate through oxygen therapy pipe 20 and output oxygen to the water in the shrimp culture pond 10, simultaneously because the water flows the foul to the middle part gathering that makes bottom of the pool 11, and the foul suction pipe 30 can concentrate the foul suction shrimp culture pond 10 of bottom of the pool 11 middle part, can oxygenate the square pond of south america white shrimp, can in time clear up 11 foul in the bottom of the pool of the culture pond simultaneously.
Example 2
The litopenaeus vannamei square pond culture sewage discharge system in the embodiment is substantially the same as the litopenaeus vannamei square pond culture sewage discharge system in the embodiment 1, and the main difference is the shape of the pond bottom 11.
As shown in fig. 3-6, the bottom 11 of the shrimp pond 10 is provided with a dirt holding plane 12 with a horizontal position lower than the main body of the bottom 11, the main body of the bottom 11 is an inclined plane gradually decreasing from the peripheral edge to the dirt holding plane 12, the length of the dirt suction pipe 30 is matched with the extending length of the dirt holding plane 12, and the dirt suction pipe 30 is arranged above the dirt holding plane 12. The bottom 11 is a continuous curved surface, and the top of the sewage suction pipe 30 is lower than the peripheral edge of the bottom 11.
Because the main body of the pool bottom 11 is an inclined plane, the air input by the oxygen input tube 20 drives the dirt in the pool bottom 11 to move to the middle part of the pool bottom 11, and when the dirt moves to the middle part of the pool bottom 11, the dirt naturally sinks on the dirt containing plane 12, which has the advantages that: firstly, the dirt can be enriched at the dirt containing plane 12, and the air input by the second oxygen input pipe 20 cannot directly impact the dirt enriched at the dirt containing plane 12, so that the dirt can be conveniently absorbed by the dirt suction pipe 30.
As shown in fig. 5 and 6, the dirt suction pipe 30 is provided with two rows of dirt suction ports 31, and the two dirt suction ports 31 face a butt joint included angle 121 at the connection position of the dirt holding plane 12 and the inclined plane of the tank bottom 11 in the length direction of the dirt holding plane 12. At this time, the dirt suction port 31 of the dirt suction pipe 30 can clean substantially all of the dirt on the dirt holding plane 12.
Different from the embodiment 1, when the culture sewage system is used, oxygen can be firstly supplied through the oxygen supply pipe 20, oxygen supply is stopped after a period of time, dirt is enriched on the dirt containing plane 12, and then water is discharged through the dirt suction pipe 30 to suck the dirt, so that the effect is better.
Example 3
The litopenaeus vannamei square pond culture sewage system in the present embodiment is substantially the same as the litopenaeus vannamei square pond culture sewage system in embodiment 1, and is mainly distinguished by a bracket 40 used in cooperation with the sewage suction pipe 30.
As shown in fig. 4, the bottom of the soil pick-up pipe 30 is provided with a bracket 40, and the bracket 40 is used for supporting the soil pick-up pipe 30 and spacing the bottom of the soil pick-up pipe 30 from the soil holding plane 12, which has the advantages that the soil pick-up port 31 of the soil pick-up pipe 30 is not attached to the bottom 11 of the tank, and the soil pick-up port 31 is prevented from being out of order.
Preferably, the support 40 includes a middle pipe bracket 41 and a leg, the middle pipe bracket 41 is a hemisphere with an opening facing upward, and the middle pipe bracket 41 is supported at the bottom of the soil suction pipe 30. The support legs are respectively positioned at the left side and the right side of the middle pipe bracket 41, and the two support legs respectively extend towards the direction far away from the middle pipe bracket 41 to form a support on the inclined plane of the main body of the tank bottom 11. The middle pipe bracket 41 has a similar buckling effect, namely the top opening of the middle pipe bracket 41 is less than 180 degrees, and the middle pipe bracket can be clamped on the sewage suction pipe 30.
The legs are upwardly curved, which form the side tube brackets 42; the sewage suction pipes 30 are arranged in parallel at intervals, the sewage suction pipes 30 at the middle part are arranged in the middle pipe bracket 41, the sewage suction pipes 30 at two sides are respectively lapped on the side pipe bracket 42, and the sewage suction pipes 30 at two sides and the inclined plane of the pool bottom 11 are arranged at intervals to realize better sewage suction effect.
Preferably, the dirt suction pipe 30 is provided with a dirt suction port 31, the dirt suction port 31 of the dirt suction pipe 30 located in the middle is directed to the middle of the dirt containing plane 12, and the dirt suction ports 31 of the dirt suction pipes 30 located at two sides are directed to the butt joint included angle 121 at the connection position of the dirt containing plane 12 and the inclined plane of the tank bottom 11 in the length direction of the dirt containing plane 12.
The south america white shrimp square pond culture sewage discharge system does not need manual cleaning of bottom of the pool dirt any more, and the concentrated cleaning of bottom of the pool 11 dirt can be accomplished to the in-process of oxygenating in the shrimp culture pond 10, and the rethread soil pick-up pipe 30 is when changing water the way realize the soil pick-up can, design benefit low cost.
The foregoing is only a preferred embodiment of the present invention, and many variations in the specific embodiments and applications of the invention may be made by those skilled in the art without departing from the spirit of the invention, which falls within the scope of the claims of this patent.
