Description
Technical field
The present invention relates to the oxygenating device field, particularly three-dimensional water body exchanges pneumatic oxygen-increasing device.
Background technology
The type that is used for the oxygenating machine of aquaculture or sewage purification at present emerges in an endless stream, use have more widely that jet is water jet, the oxygenating machine of types such as vane type, water wheel type and micro-pore aeration formula.Wherein, vane type and jet water-spraying oxygen-increasing machine all adopt goes out jet of water, makes it to contact with air, mixes and reach the oxygenation purpose.Waterwheel aerator is to utilize blade in shoaling layer, to carry out paddling, causes great waves, and the contact area that increases the water surface and air realizes oxygenation.These oxygenating machines just carry out oxygenation to the top layer water surface, and oxygenation effect is not good, and the obnoxious flavour of bottom water body can not be by effective elimination.Be exactly that these devices nearly all adopt motor as motivating force one water surface operation that coexists in addition, cause potential safety hazard.
The micro-pore aeration oxygenating machine utilizes blower fan that air is squeezed in the water, with dissolved oxygen, though effect increase,, lay long oxygen supply pipeline on the water under water.When the bubble that aeration tube produces infiltrates water body with vertical form; The buoyancy that receives is bigger; Cause oxygen shorter in the time of melting that water body is participated in; Because existing micro-pore aeration oxygenating machine all is to be fixed in pond bottom, is difficult to realize that air and water body advance to wider scope, also can't realizes the water body interchange on a large scale of the upper and lower layer of water body and consume energy higher.
How forming dissolved convection current on a large scale, circulation, solve the drawback that the aeration oxygen increasing machine energy consumption is high, the aeration scope is little, is those skilled in the art's problem demanding prompt solutions.
Summary of the invention
The object of the present invention is to provide a kind of pneumatic oxygen-increasing device.
According to an aspect of the present invention, the pneumatic oxygen-increasing device that provides comprises blower fan and rotating mechanism, and this rotating mechanism comprises interior pipe, outer tube and bearing; On managing in bearing housing is located at; Outer tube sleeve is located on the bearing, and interior pipe or outer tube upper end link to each other with blower fan through pipeline, and interior pipe or outer tube bottom outer wall are provided with outward extending pivot arm; Pivot arm is provided with the Venturi shower nozzle, and interior pipe or outer tube bottom link to each other through being in charge of with the Venturi shower nozzle.
Adopt technique scheme; Pneumatic oxygen-increasing device of the present invention realizes that the principle of three-dimensional oxygen supply of water body is: the oxygen that blower fan produces is in the interior pipe or outer tube of passage input rotating mechanism; And arrive in the Venturi shower nozzle of installing on each pivot arm; Because pivot arm one end is interior pipe or the outer tube bottom outer wall that is fixed on rotating mechanism, the Venturi shower nozzle is fixed on the pivot arm again; When the Venturi shower nozzle gos deep into underwater operation under 0.01～0.3MPa pressure according to Bernoulli's theorem; Oxygen is extruded from the hole of Venturi shower nozzle; The air pressure that is produced water sucked during greater than hydraulic pressure carry out gas in the Venturi shower nozzle, water mixes; And be injected in a large amount of micro bubbles of generation in the pond waters, and under the promotion of air pressure, air-water mixture outwards being sprayed fast, the reactive force of this strand jet power has just formed a kind of impellent.This strand that respectively forms from the Venturi shower nozzle made a concerted effort, and promotes pivot arm and does the circumference rotation, increases the aeration radius, prolonged the duration of contact of oxygen and water body.Can also part Venturi shower nozzle be installed along the pivot arm direction of principal axis, its nozzle is outside, and air-water mixture is dished out more in large area.
In addition, at least one group of impeller is installed on pivot arm.Also rotation thereupon of the reason impeller of water resistance in pivot arm motion, its blade paddling that in water, circulates is transferred to the gas that sprays in the Venturi shower nozzle rotating range, water mixture, and the water that will have neither part nor lot in dissolved oxygen is simultaneously introduced and promoted the water body circulation; Increase the contact of empty G&W simultaneously.Water body behind the dissolved oxygen fully is exposed to the sun under ultraviolet ray, has strengthened the effect of ultraviolet ray, can eliminate the part multiple mushrooms such as green alga and intestinal bacteria in water that swim, can promote that useful algae and the planktonic breeding in the water body grown water body.Through continuous circulation with water body behind the dissolved oxygen of bottom and surface water; Realize a kind of effect of the similar ventilation of windowing, some degraded materials are distributed from water body, play the effect of water body purification; Eliminate the content of stink and nitrogen, make water quality limpid.
The mode of plugging into of rotating mechanism and blower fan and Venturi shower nozzle has two kinds; One, the inlet mouth with interior pipe top is connected with blower fan through air-supply duct; Pipe bottom in be longer than the outer tube bottom, its outlet side is communicated with the Venturi shower nozzle through flexible pipe or pivot arm cavity provides oxygen.Two, the inlet end on outer tube top is connected with blower fan through air-supply duct; In the pipe bottom be longer than the outer tube bottom, its outlet side is communicated with the Venturi shower nozzle through flexible pipe or pivot arm provides oxygen.
In certain embodiments, for the ease of flexible pipe and the installation of plugging into, said outer tube lower end or interior pipe lower end are provided with terminal pad, and terminal pad is provided with a plurality of pipe that communicate with outer tube or interior pipe, and described Venturi shower nozzle links to each other with pipe through flexible pipe.
In certain embodiments, the pipeline that on interior pipe or outer tube, links to each other with blower fan is provided with doser, and the medicine in this doser is gas or liquid or pulvis.Pressure through blower fan is discharged medicine from the micropore of Venturi shower nozzle, can make medicine fast, be dissolved in the water body uniformly, thereby improve drug effect.
In certain embodiments, the Venturi shower nozzle is fixed in the terminal and parallel with the water surface of pivot arm.Design not only helps enlarging the oxygen supply zone of Venturi shower nozzle like this, makes that also rotation is more light, laborsaving.
In certain embodiments, in order to increase the oxygen supply scope, along the pivot arm direction of principal axis its nozzle to be installed outside with being arranged on a plurality of Venturi shower nozzles parts on the pivot arm, makes that air-water mixture is more large-area dishes out.
In certain embodiments, to connect more closely and compact more in order making between interior pipe, outer tube, the bearing, to be provided with the bearing limited step at outer wall of inner tube, outer tube wall is provided with the bearing positive stop lug boss.
In certain embodiments, in order to reduce gas leakage and protection bearing between the inner and outer pipe, be provided with ring flange in the upper end or the lower end of interior pipe or outer tube.Can also between inner and outer pipe, fill in order to sealing or lubricated weighting material.
In certain embodiments, can adopt the lower end of outer tube or the lower end portion of giving vent to anger of interior pipe to be provided with terminal pad, terminal pad is provided with a plurality of pipe.Refute pipe through flexible pipe one termination, the other end Venturi shower nozzle of plugging into is realized Venturi shower nozzle air feed.
