Abstract
The utility model relates to an Oxygen-adding machine for deepwater, which can substantially raise the culturing density and increase the profit of aquaculture. Its major technique characteristic is that the invention is composed of a submersible pump combined with a gas water mixing apparatus. The gas water mixing apparatus comprises an air intake duct, a water spraying head and a centrifugal aeration duct. After the start of the electric pump, the water in the rear pump body is quickly evacuated; air enters to the gas water mixing apparatus through the air intake duct and mixed with the water overflowed from holes of the water spraying head to form the heavy-oxygen-enriched water which is discharged in all directions after the pressurization by the centrifugal pump. The pump shaft is provided with an aeration duct to increase the oxygenation effect, which rotates as the pump shaft rotates, and shoots the inhaled air into the water body from the lower holes of the aeration duct.
Description
A kind of novel equipment for culture fishery increase water oxygen level.
At present both at home and abroad the aerator that adopts is more effective to the increase of water body top layer oxygen content, and is then powerless to the oxygen content of the low temperature oxygen deprivation water that improves water bottom.In the low weather of temperature height and air pressure, the oxygen content in the superficial water is easy to escape, and is difficult to be made full use of by fish, has influenced oxygenation effect.On the other hand, when present surface type aerator is used for fish culture in net pen, difficulty is installed, for improving oxygenation efficient (every kilowatt of hour electric of the oxygenation amount of energy), realizes the large tracts of land aeration in deep water, realize high-density aquiculture, the spy is the present invention.
General structure of the present invention as shown in drawings.Figure one is a general assembly drawing, and figure two is AA face cutaway views.6 is submersible motors among the figure, is the power of full machine.3 is impeller, the 4th, and pump cover, the 5th, the pump housing, the three constitutes one and goes up the centrifugal pump of inhaling side-type.The 1st, the air intake duct of gas-water mixer, the 2nd, the trickle head of gas-water mixer.Its operation principle is: after motor starts, the water pump vane high speed rotating, the very fast emptying of water in the pump, air is entered in the pump by air intake duct, the water of trickle head outside is under action of gravity simultaneously, pour in the blender by the aperture around the trickle head, water mixes in gas-water mixer with gas, forms heavy-oxygen-enriched water.Further mix in the stirring of impeller with under pushing again, and by delivery port to around discharge.
Delivery port on the immersible pump can be one or more, the direction of discharge water can level to around radiation, also can be tilted to down and discharge.On outlet, can be hinged with drainpipe.Drainpipe can be selected plastic tube, canvas rubber tube or fiber braided tube for use.Leave hole by certain distance on tube wall, heavy-oxygen-enriched water constantly spreads in the water by the aperture on the pipe when flowing through pipeline towards periphery, to increase the uniformity of oxygenation in the water body.
According to the operation principle of this machine, raising is fit into water depth, and is favourable to improving oxygenation effect.When improving underwater penetration, the pressure of outside water increases, and current improve by the flow velocity that the aperture on the trickle head pours in gas-water mixer, help increasing inspiratory capacity.On the other hand, the pressure that the current by pump housing delivery port are subjected to water is also big, and the oxygen that helps wherein is further water-soluble.
For further improving efficient and the uniformity that air water mixes, a centrifugal aeration tube can be installed in gas-water mixer, utilize centrifugal force to cause negative pressure, promote in the air intake pipe, and go up aperture by pipe and inject water body.
The structure of centrifugal aeration tube is shown in figure three, and on the section of a pipe of diameter less than air inlet pipe, the tube wall bottom has aperture, blade is housed in the pipe, the lower end of pipe is connected with the axis head nut of immersible pump, can rotate together in company with pump shaft during work in company with nut spinning together to pump shaft during use.
Can add an axial flow blower for improving inspiratory capacity in air inlet pipe, this axial flow blower together rotates in company with aeration tube, forces to be pressed in gas-water mixer air.
