Abstract
The utility model relates to a pure oxygen oxygenation device that is used for aquaculture. The pure oxygen oxygenation equipment oxygen utilization ratio of using both at home and abroad at present is low, and the energy consumption is on the high side, has not only wasted the resource but also increased the cost. This utility model comprises: oxygen blending tank (6), arranges ejector (3) on the said oxygen blending tank, and oxygen intake pipe (1) is connected to the ejector, and surplus oxygen intake pipe (4) is connected to the oxygen blending tank, and the oxygen blending tank is connected to the surplus oxygen intake pipe, the oxygen blending tank run-on water pipe (7), and installation level sensor (5) is connected to the oxygen blending tank. This utility model is used for aquaculture.
Description
Technical field:
The utility model relates to a kind of pure oxygen oxygen-increasing device that is used for aquaculture.
Background technology:
In the aquaculture process, the dissolved oxygen in the water is the important substance that aquatic cultivated animals is depended on for existence.Under high-density industrialized culture condition, because cultured fishes density is big, dissolved oxygen depletion is fast, needs to replenish rapidly the dissolved oxygen of water body.The pure oxygen oxygenation method has advantages such as oxygenation speed is fast, solubleness is high, energy expenditure is low, and can significantly increase the utilising efficiency of cultivation density, raising equipment.Have data to show, under the condition of oxygenating air, cultivation density can not be greater than 30～40Kg/m3, and when pure oxygen oxygenation, cultivation density can be brought up to 120Kg/m3.Pure oxygen oxygenation can be given full play to the advantage of industrialized aquiculture, increases economic benefit.But because pure oxygen derives from oxygenerator or canned pure oxygen, oxygenation needs certain source of the gas cost.Therefore, oxygen fully being dissolved, improve oxygen utilization rate, cut the waste, is the greatest factor of pure oxygen oxygen-increasing device design, also is the words important technology index of pure oxygen oxygenating device.
The pure oxygen oxygenating device that uses both at home and abroad mainly contains at present: U type pipe, downflow system bubble contactor, packed column etc., oxygen utilization rate is respectively 30%～50%, 80%～90%, 40%～80%.Downflow system bubble contactor and U type pipe all need the pressure about 100KPa, and energy consumption is higher; The oxygen utilization rate of packed column when not pressurizeing is about 40%-80%, shows that the undissolved oxygen of residue has 20%-60% to be wasted, fail fully with water blended pure oxygen gas directly with the current discharge, not only wasted resource but also increased cost.
Summary of the invention:
The purpose of this utility model is to provide a kind of pure oxygen oxygen-increasing device that is used for aquaculture at the higher and low problem of utilization ratio of the energy consumption of the pure oxygen oxygenation of above-mentioned existence, can effectively improve pure oxygen utilization ratio, increase aquaculture water concentration of oxygen gas, reduce cost.
Above-mentioned purpose realizes by following technical scheme:
The pure oxygen oxygen-increasing device that is used for aquaculture, its composition comprises: the oxygen mix jar, on the described oxygen mix jar ejector is installed, described ejector connects oxygen intake pipe, described oxygen mix jar connects the remaining oxygen inlet pipe, described remaining oxygen inlet pipe connects described oxygen mix jar, and described oxygen mix jar connects water shoot, and described oxygen mix jar is connected and installed water level sensor.
The described pure oxygen oxygen-increasing device that is used for aquaculture has the oxygen pressure variable valve on the described oxygen intake pipe, have magnetic valve on the described water shoot.
Beneficial effect:
1. the utility model adopts the design that ejector combines with mixing tank, shears the pure oxygen bubble and also makes it acutely to mix with water, and also remain the recovery of pure oxygen gas the duration of contact of increase pure oxygen and water; This device can effectively improve pure oxygen utilization ratio, increase aquaculture water concentration of oxygen gas, reduce cost, be a kind of efficient oxygenating device of industrialized aquiculture.Pure oxygen oxygenation utilization ratio height can reach 100%, conserve oxygen.
2. the speed of the utility model oxygenation, solubleness can be controlled with the oxygen pressure control valve as required.
3. the utility model concentration of oxygen gas height, oxygenation speed is fast, and simple in structure, and cost is low.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment:
Embodiment 1:
The pure oxygen oxygen-increasing device that is used for aquaculture, its composition comprises: oxygen mix jar 6, ejector 3 is installed on the described oxygen mix jar, described ejector connects oxygen intake pipe 1, described oxygen mix jar connects remaining oxygen inlet pipe 4, described remaining oxygen inlet pipe connects described oxygen mix jar, and described oxygen mix jar connects water shoot 7, and described oxygen mix jar is connected and installed water level sensor 5.
Embodiment 2:
The described pure oxygen oxygen-increasing device that is used for aquaculture has oxygen pressure variable valve 2 on the described oxygen intake pipe, have magnetic valve 8 on the described water shoot.
Working process:
The aquaculture water that lacks dissolved oxygen forms high velocity flow under the effect of water pump, water inlet by ejector 3 enters ejector, under the effect of ejector jet water course, forms negative pressure in the ejector, oxygen is inhaled into ejector 3 by managing 1, enter mixing tube, acutely mix with high velocity flow, mixed air-water mixture enters mixing tank 6 by diffuser tube, and in mixing tank, continue to dissolve, make water body become heavy-oxygen-enriched water, discharge mixing tank, be used for aquaculture by water shoot 7.In the current mixing process of not dissolved oxygen in mixing tank, rise to the top of mixing tank gradually, and enter ejector 3, mixed, utilize by ejector once more, thereby reach the purpose that makes full use of by residual air pipe 4.
Oxygen pressure variable valve 2 can be regulated the speed and the efficient of oxygenation, to adapt to the needs that different dissolved oxygen consumes.Opens solenoid valve 8 when starting working that water level sensor 5 is used for device; When water level did not reach the solenoid control water level, magnetic valve 8 cut out, not draining of water port; When water level reached the control water level, magnetic valve 8 was opened, water port draining, device works better.The water level control line is the gauging line that the draining unanimity is advanced in control, makes the flooding quantity of ejector water inlet consistent with the water displacement of water shoot 7.
Claims (2)
1. pure oxygen oxygen-increasing device that is used for aquaculture, its composition comprises: the oxygen mix jar, it is characterized in that: on the described oxygen mix jar ejector is installed, described ejector connects oxygen intake pipe, described oxygen mix jar connects the remaining oxygen inlet pipe, described remaining oxygen inlet pipe connects described oxygen mix jar, and described oxygen mix jar connects water shoot, and described oxygen mix jar is connected and installed water level sensor.
2. the pure oxygen oxygen-increasing device that is used for aquaculture according to claim 1 is characterized in that: have the oxygen pressure variable valve on the described oxygen intake pipe, have magnetic valve on the described water shoot.
