Abstract
The utility model discloses an oxygenation device with a buried pipe at the bottom of a seedling growing pool, which aims to solve the problems that conventional flexible pipes and air stone aerating and oxygenation devices for fish and shrimp seedling growing pools are not easy in installation, the production operation is hampered and pathogenic bacteria are provided with a breeding environment in the prior art. By utilizing the oxygenation device of the utility model, the survival rate of the seedling in the pool is increased and the water space of the seedling growing pool is saved. Meanwhile, the environment is concise and clean. The oxygenation device comprises a bottom-buried air pipe, air holes, an inverted U-shaped air conduit, a valve, a main air duct and an air blower. Compressed air provided by the air blower escapes from the bottom of the seedling growing pool via the main air duct, the inverted U-shaped air conduit, the valve, the bottom-buried air pipe and the air holes to provide oxygen and aeration for the seedling growing pool. The bottom-buried air pipe is a PVC hard water supply pipe buried at the bottom of the seedling growing pool when the seedling growing pool is built or reconstructed. The upper edge of the bottom-buried air pipe is flush with or slightly lower than the bottom of the seedling growing pool. The inverted U-shaped air conduit is connected with the main air duct and the bottom-buried air pipe. The highest position of the U-shaped air conduit is higher than the highest water level in the seedling growing pool.

The utility model designs according to the needs of nursery pond blowing aeration, and it is achieved in that
Embedded inflating type oxygen-increasing device at the bottom of a kind of fishes and shrimps nursery pond, it comprises that the end buries tracheae (1), inverted U-shaped tube connector (11), control valve door (10), main gas tube (12) and blower fan (8).The PVC hard feed pipe at the bottom of tracheae (1) is embedded in nursery pond when building at nursery pond or transforming is buried at the described end, the tracheae upper limb is buried at the end and pond basal surface (13) is fair or lower slightly, tracheae is buried at the described end pore (6), described pore (6) is distributed in the end and buries the upper limb of tracheae (1), build up the back and hole with puncher at the bottom of nursery pond, the aperture is 0.4mm; The peak of described inverted U-shaped tube connector (11) must be higher than the peak level of nursery pond, and larval rearing water enters the end by pore and pours in down a chimney into main gas tube (12), blower fan (8) passage after burying tracheae (1) when preventing to stop blowing aeration; Described inverted U-shaped tube connector (11) buries tracheae and is connected with inverted U-shaped tube connector (11) with inverted U-shaped tube connector junction (7) end of at; Described control valve door (10) is mainly used in the adjusting air inflow; Described blower fan (8) is used to provide the air of capacity.
The hard feed pipe that tracheae, inverted U-shaped tube connector, main gas tube are the PVC material is buried at the above-mentioned end, and diameter is 13mm, can be from commercial purchase.
The angle control air inflow of above-mentioned valve by opening is the PVC material, can be from commercial purchase.
The blower fan that the utility model relates to also can be from commercial purchase.
Buried tracheae oxygen-increasing device in the end of the present invention and using method have solved traditional flexible pipe, the difficult installation of gas stone oxygenation well, pathogen is returned in the obstruction production operation provides drawbacks such as growing the place, further improve weed survival rate, saved the water body space of nursery pond simultaneously, succinct, a clean environment also can be provided.Be fit to the batch production of fishes and shrimps seed, large-scale cultivation.
Description of drawings
Fig. 1: be the utility model device schematic top plan view.
Fig. 2: be the utility model structure front schematic view.
Number description is as follows: bury tracheae at the bottom of the 1-; The 2-discharge outlet; Bury between tracheae at the bottom of the 3-and connect; The 4-drainpipe; 5-nursery pond body of wall; The 6-pore; The inverted U-shaped tube connector of 7-buries tracheae the end of with and is connected; The 8-blower fan; The 9-water inlet pipe; 10-control valve door; The inverted U-shaped tube connector of 11-; The 12-main gas tube; At the bottom of the 13-nursery pond pond.
Embodiment
Present embodiment is that the design philosophy that " summary of the invention " and the attached Fig. 1 and 2 according to this specification proposed completes.
With the cement nursery pond of building a 400cm * 400cm * 80cm is example.In the utility model, cement casting thickness at the bottom of the pond of reservation 2cm, tube connector in the pre-buried feeding pond, finish the capital construction work of 400cm * 400cm * 76cm cement nursery pond, then lay the end and bury tracheae at the bottom of the pond, bury tracheae and be arranged into three-back-shaped (accompanying drawing 2) according to the even oxygen aeration principle at the end, pour into a mould the cement of 2-4cm then, the discharge outlet place is low, slightly high in order to draining on every side in the middle of being at the bottom of the pond, and the upper-lower position of tracheae is buried at the suitable adjustment end during cast, makes the end bury the tracheae upper limb and maintains an equal level all the time with at the bottom of the nursery pond.After waiting to the cement solidifies, bury every interval 50cm boring on the water pipe, aperture 0.4mm the end of at.Install tube connector, inverted U-shaped tube connector, valve, install, seal sewage draining exit, connect the wireway or the main gas tube that are connected with blower fan, buried tracheae oxygen-increasing device is installation at the end.
Using method of the present utility model (is example to cultivate the yellow cartfish seed in nursery pond) is as follows: (1) will meet the water of cultivating yellow cartfish seed water quality requirement and inject nursery pond by water inlet, throw in the advanced fry of yellow catfish of respective numbers, treat to begin to throw something and feed after fry conforms satisfactory bait; (2) open blower fan, open the valve of the buried tracheae oxygen-increasing device in the end as required, air can bury tracheae the end of by and slowly rise to the water surface at the bottom of nursery pond, and oxygen is dissolved in the water, reach oxygenation, aeration purpose, can control air inflow by the angle of adjusting valve.When (3) need not to use, valve-off gets final product.
Result of use: (1) oxygenation effect, through measuring, the buried tracheae oxygen-increasing device in the end can make the dissolved oxygen of nursery pond rise to 7.54 mg/litre from 6.41 mg/litre, and comparison increases by 15% dissolved oxygen according to the pond, and oxygenation effect is obvious.(2) improve the weed survival rate effect.The buried tracheae oxygen-increasing device in the end has overcome original flexible pipe, gas stone oxygenation way takies limited seedling water, is easy to drawbacks such as germ grows, and has improved survival rate of young.(3) reduced production cost because the buried tracheae in the end is embedded at the bottom of the pond, with flexible pipe, gas stone formula OER, material is more difficult aging, prolong service life, reduced production cost; (4) effect of beautifying the environment does not have crisscross fixedly iron wire, rope and the flexible pipe that always is intertwined, gas stone, for the work of growing seedlings provides succinct, a clean environment.
