Abstract
A centrifugal outer tube aeration automatic aerator comprises a drive set, which is characterized in that: the drive set is connected with a capstan shaft; the capstan shaft from top to bottom is respectively provided with a pressurizing impeller and a combined revolving solid; the capstan shaft at the pressurizing impeller is outside sleeved by a oxygen inletting outer tube, and the lower end of the oxygen inletting outer tube is provided with the combined revolving solid; the outer side of the combined revolving solid is provided with an airscrew blade, and the lower end of the airscrew blade is provided with an extroversive type air-out channel. The centrifugal outer tube aeration automatic aerator has a simple structure and convenient maintenance. The air-in pressure and the air input are increased through the two groups of pressurizing impeller and the airscrew blade in the lower combined revolving solid; the air is thrown out from the extroversive type ring-shaped channel and is pressurized and broken up to form current aerated fully through the retroverted blade at the end to fully convect and increase oxygen in the whole water; therefore, the oxygen increasing effect is obviously improved at low energy consumption. The aeration automatic aerator can be widely applicable to the water oxygen increasing in aquiculture or sewage purification.
Description
Technical field
The utility model belongs to aquaculture or sewage purification oxygen increasing equipment, is specifically related to the centrifugal outer tube aeration oxygen increasing machine that a kind of oxygenation effect is remarkable, the oxygenation scope is big.
Background technology
The type of aerator that is used for aquaculture or sewage purification at present is varied, mainly contains that jet is water jet, vane type, Waterwheel-type and aeration type.Vane type and jet water-spraying oxygen-increasing machine all adopt water are ejected, and 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 aerator all can only carry out oxygenation to the top layer water surface, and the pernicious gas 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 admission pressure simultaneously, consumes very big electric energy.
The inventor thinks that the problem that present aeration oxygen increasing machine exists mainly is that structural design is unreasonable, when entering water body, air is vertical downward direction, the buoyancy that is subjected to is bigger, the dissolved oxygen time of water body is short, the propeller blade that drives the water body circulation in addition enters to wider scope in order to realize air and water body, its direction that drives current can't realize large-scale convection current for radially or axial direction.
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 centrifugal outer tube aeration oxygen increasing machine of aeration convection current on a large scale, has solved existing aeration oxygen increasing machine energy consumption height, complex structure, drawback that the aeration scope is little.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of centrifugal outer tube aeration oxygen increasing machine, comprise drive unit, it is characterized in that connecting on the drive unit capstan, supercharging impeller and combination rotary body from top to bottom are set respectively on the capstan, the capstan overcoat at supercharging impeller place is put into the oxygen outer tube, advance oxygen outer tube lower end assembly rotary body, combination rotary body arranged outside propeller blade, its lower end is provided with the external inclined type outlet passageway.
Specifically, the described combination rotary body of this centrifugal outer tube aeration oxygen increasing machine have one with advance the inner rotary housing that oxygen outer tube lower end cooperates, inner rotary housing lower end is for extending out the shape horn mouth, and it extends out shape horn mouth and lower end has between the interior rotary shell of horn mouth structure and form outlet passageway.
Described inner rotary housing is fixedlyed connected with interior rotary shell, fixedly installs helical blade between the top of interior rotary shell and inner rotary housing, and the upper end of inner rotary housing connects capstan.
The upper end of described combination rotary body inner rotary housing with enter oxygen outer tube lower end and be end to end anastomosis, described propeller blade is terminal BI blade, stationary distribution is at the outer wall of described shell body.
Described drive unit is electromotor or mechanical actuation device.
Described supercharging impeller is two, is separately positioned on the capstan of into oxygen outer tube upper port and lower port place.
Describedly advance the lower end caliber of oxygen outer tube less than its upper end caliber.
The outlet passageway of the lower end of described combination rotary body is downward external inclined type circular passage.
The parts that are somebody's turn to do outer tubular type aeration oxygen increasing machine are less and simple in structure, the part body that advances the oxygen outer tube is positioned at the underwater, its upper end mouth of pipe air inlet, and after carrying out supercharging through two groups of supercharging impellers, form the air-flow body of big oxygen supply pressure, and can continue supercharging by the helical blade of combination a rotating body, at last under the effect of the rotary centrifugal force that makes up rotary body, the inclined annular outlet passageway that has a down dip by its lower end gets rid of in the water body, the deep-water pressure that terminal BI blade rotation is produced increases outlet passageway place air and pressure on every side, air is pulverized to stir and fully dissolve with water body on a large scale to be mixed, form the convection current of full pond, make deep water and farther place water body can access abundant oxygenation.
The beneficial effects of the utility model are, this centrifugal outer tube aeration oxygen increasing machine is simple in structure, easy to maintenance, helical blade by two groups of supercharging impellers and following combination a rotating body improves admission pressure and air inflow, and throw away by the outer incline circular passage, and smash the current that form abundant aeration through the supercharging of terminal BI blade, whole water body is carried out abundant convection current oxygenation, 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
