Description
Technical field
The utility model belongs to cultivation seedling-cultivating tool technical field, particularly relates to a kind of aquaculture and grows seedlings to produce and change water device.
Background technology
In recent years, China Water product cultured output accounted for 2/3 of World Water product cultivating output, can say, Chinese Fishery aquaculture ensure national food safely, expand employment, increase farmers' income, improve the aspects such as water area ecological environment and made significant contribution.In aquaculture seedling raising process, in order to guarantee that water quality is pure and fresh, need to refresh the water periodically.It is more difficult that aquaculture is at present changed water in growing seedlings and producing, some use net cages carry out, and application water pump carries out draining, like this complex operation, the utensil cost using is higher, and easily because improper use causes seedling, we am adsorbed in appearance death on net cage wall in drainage procedure.With regard to the drainage arrangement that causes using, often there is the problems such as the easy death of aquatic seedling in this.Therefore, need a kind of structure more rationally, practical, drainage arrangement easily.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of aquaculture and grows seedlings to produce and change water device, controls flexibly the flow of nursery pond discharge of wastewater by siphon principle, reduces the lethality of growing seedlings in drainage procedure.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of aquaculture to grow seedlings to produce and change water device, comprise apparatus main body, the circular tubulose of described apparatus main body, described apparatus main body middle part radially connects siphon pipe, described siphon pipe one end connects siphon device, the other end penetrates apparatus main body and is connected with apparatus main body and is " T " font, described siphon pipe enters on one end tube wall of apparatus main body to have a plurality of suction holes, and a filtering cover is respectively installed at described apparatus main body two ends.
Filtration bolting silk is housed on described filtering cover, and described filtration bolting silk order number is per inch 10 to 80 orders.
Between described filtering cover and apparatus main body, become to removably connect.
Between described filtering cover and apparatus main body, be to be threaded.
In described filtering cover flush mounting main body, between described filtering cover and apparatus main body, be interference fits.
Described aquaculture is grown seedlings and is produced the using method of changing water device, and step is as follows:
A, according to the Individual Size of aquatic product sprout growth different phase, select suitable filtering cover, the filtration bolting silk order size of described filtering cover is less than the Individual Size of aquatic product sprout;
B, filtering cover is cleaned out and is installed to apparatus main body two ends;
C, siphon pipe one end is connected to siphon device;
D, open siphon device, lid to be filtered place produces the middle and lower part of putting into the nursery pond of water to be changed after negative pressure, and Chi Shui starts outer row because of negative pressure;
E, stop when Chi Shui is discharged into the 1/4-1/3 place of Chi Shui in nursery pond, with another water pipe, this nursery pond is supplemented to fresh water to former water level, the water quality of water inlet will meet the requirements;
F, repetition A to E step, until complete draining.
Beneficial effect
The utility model has the advantage of, by the suction hole having on siphon principle and siphon pipe one end tube wall, control flexibly the flow of nursery pond discharge of wastewater, reduce the lethality of growing seedlings in drainage procedure; Filtering cover can be dismantled, and is convenient to clean, sterilize; Seed is individual to be retained in pond because of the filtration bolting silk on device, and waste water is discharged from by device, and then continues to add new water, larval rearing water is retained fresh, guarantees the growth needs of seed.Whole device is simple to operate, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, a kind of aquaculture is grown seedlings to produce and is changed water device, comprise apparatus main body 1, the circular tubulose of described apparatus main body 1, described apparatus main body 1 middle part radially connects siphon pipe 2, described siphon pipe 2 one end connect siphon devices, the other end penetrates apparatus main body 1 and is connected with apparatus main body 1 and is " T " font, and described siphon pipe 2 enters on one end tube wall of apparatus main body 1 to have a plurality of suction holes, and a filtering cover 3 is respectively installed at described apparatus main body 1 two ends.
On described filtering cover 3, filtration bolting silk is housed, described filtration bolting silk order number is per inch 10 to 80 orders.
Between described filtering cover 3 and apparatus main body 1, become to removably connect.
Between described filtering cover 3 and apparatus main body 1, be to be threaded.
In described filtering cover 3 flush mounting main bodys 1, between described filtering cover 3 and apparatus main body 1, be interference fits.
Described aquaculture is grown seedlings and is produced the using method of changing water device, and step is as follows:
A, according to the Individual Size of aquatic product sprout growth different phase, select suitable filtering cover 3, the filtration bolting silk order size of described filtering cover 3 is less than the Individual Size of aquatic product sprout;
B, apparatus main body 1 two ends are cleaned out and be installed to filtering cover 3;
C, siphon pipe 2 one end are connected to siphon devices;
D, open siphon device, lid to be filtered 3 places produce the middle and lower part of putting into the nursery pond of water to be changed after negative pressure, and Chi Shui starts outer row because of negative pressure;
E, stop when Chi Shui is discharged into the 1/4-1/3 place of Chi Shui in nursery pond, with another water pipe, this nursery pond is supplemented to fresh water to former water level, the water quality of water inlet will meet the requirements;
F, repetition A to E step, until complete draining.
In actual production process, seed high-density growth is in same water body, seed grows into individual larger seed from individuality is less, need to select suitable filtration bolting silk order number according to the size of seed growing seedlings in changing water process, filtering cover of the present utility model is detachable, can change in time the filtering cover with corresponding filtration bolting silk order number according to seed size on the one hand, be convenient on the other hand clean and sterilization.
The water that adopts the utility model to carry out larval rearing water by siphon principle discharges, and can regulate drain discharge by changing the mode of water-head.Siphon pipe has a plurality of suction holes, effectively reduces water velocity in siphonic process, prevents that aquatic product sprout is adsorbed on for a long time on filtering cover by current and causes death.Quantity of exchanged water generally remains on 1/3-1/4, and then adds new water, larval rearing water quality guarantee is held fresh, guarantees the growth needs of seed.
