Abstract
Disclosed is an external-tube type aeration oxygen enriching machine which comprises a drive gear. The utility model is characterized in that a drive capstan is connected to the drive gear; two pressure impellers and a screw propeller are arranged from the top to the bottom on the drive capstan; an oxygen inlet cylinder is sleeved outside a drive capstan sleeve at the pressure impellers and a guide shell is arranged outside the lower part of the oxygen inlet cylinder. The external-tube type aeration oxygen enriching machine is simple in structure and convenient for maintenance; the inlet pressure and the inlet quantity are improved due to the two pressure impellers, the water flow which is scattered by the screw propeller to achieve full aeration is forced to be in diffusion convection under the action of the guide shell for achieving full aeration and oxygen enrichment to the whole water body, therefore the oxygen enriching effect can be evidently improved under the condition of low energy consumption. The aeration oxygen enriching machine can be widely applied to the water body oxygen enrichment in the places for aquiculture or sewage purification.
Description
Technical field
The utility model belongs to aquaculture or sewage purification oxygenating device, is specifically related to the outer tubular type aeration oxygen increasing machine that a kind of oxygenation effect is remarkable, the oxygenation scope is big.
Background technology
The type of oxygenating machine that is used for aquaculture or sewage purification at present is varied, mainly contains that jet is water jet, vane type, water wheel type and aeration type.Vane type and jet water-spraying oxygen-increasing machine all adopt goes out jet of water, it is contacted with air reach the oxygenation purpose.Waterwheel aerator is to utilize blade to pat in shoaling layer, causes great waves, and the contact area that increases the water surface and air realizes oxygenation.Above-mentioned oxygenating machine all can only carry out oxygenation to the top layer water surface, and the obnoxious flavour in the bottom water can not effectively be eliminated, and oxygenation effect is not good.Existing aeration oxygen increasing machine utilizes motor that air is squeezed in the water, and with dissolved oxygen, though effect increases, the structure of aeration oxygen increasing machine is very complicated, needs to form bigger intake pressure simultaneously, consumes very big electric energy.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, energy consumption is low, the oxygenation scope is big, can form the outer tubular type aeration oxygen increasing machine of aeration convection current, has solved the drawback of existing aeration oxygen increasing machine energy consumption height, complex structure, inconvenient maintenance.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of outer tubular type aeration oxygen increasing machine, comprise drive unit, it is characterized in that connecting capstan on the drive unit, supercharging impeller and water screw from top to bottom are installed respectively on the capstan, the capstan overcoat at supercharging impeller place is put into the oxygen tube, advances the outside coaxial package guide shell of oxygen tube lower end.
Specifically, the described drive unit of this outer tubular type aeration oxygen increasing machine is electric motor or mechanical actuation device.
Described supercharging impeller is two, is separately positioned on the capstan of into oxygen tube upper port and lower port place.
Describedly advance the lower end barrel dliameter of oxygen tube less than its upper end barrel dliameter.
Described guide shell with advance the oxygen tube and fixedly connected, the lower end and the water screw of guide shell are horizontally disposed with.
Outside flare of the upper port of described guide shell and lower port or cone expansion.
The parts that are somebody's turn to do outer tubular type aeration oxygen increasing machine are less and simple in structure, the part cylindrical shell that advances the oxygen tube is positioned at the underwater, its upper port air inlet, and after carrying out supercharging through two groups of supercharging impellers, form the air-flow body of big oxygen-supplying amount, and by the current thorough mixing that enters with guide shell after the water screw pulverizing, guide shell will be rich in the current direction swallow guiding of gas, can form the convection current of whole water body, make the water of deep layer and the water body in farther waters all can realize oxygenation.
The beneficial effects of the utility model are, it is simple in structure, easy to maintenance to be somebody's turn to do outer tubular type aeration oxygen increasing machine, improve intake pressure and air input by two groups of supercharging impellers, and smash the current that form abundant aeration by water screw, under the effect of guide shell, carry out the diffusion type convection current, whole water body is carried out abundant aeration oxygen replenishing, under the lower condition of energy consumption, significantly improved oxygenation effect.This aeration oxygen increasing machine can be widely used in the water body oxygenation of occasions such as aquaculture or sewage purification.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Fig. 1 is a cut-away section structural representation of the present utility model.
Embodiment
As figure, outer tubular type aeration oxygen increasing machine mainly by motor 1, capstan 4, supercharging impeller 2 and 5, water screw 6, advance oxygen tube 3 and guide shell 7 is formed.Connect capstan 4 on the motor 1, two supercharging impellers 2 and 5 and water screws 6 from top to bottom are installed respectively on the capstan, and the capstan overcoat of supercharging impeller outer is put into oxygen tube 3, enters the lower end of oxygen tube and inwardly shrinks, the lower end barrel dliameter that advances the oxygen tube is less than its upper end barrel dliameter, to increase intake pressure.Supercharging impeller 2 and 5 is separately positioned on the capstan of into oxygen tube upper port and lower port place.Advance the outside coaxial package guide shell 7 of oxygen tube lower end, guide shell with advance the oxygen tube and fixedly connected, the lower end and the water screw of guide shell are horizontally disposed with, the outside tapered expansion of the upper port of guide shell and lower port.
