Description

A kind of novel pipe oxygenation aerating apparatus

(1) technical field

The utility model relates to a kind of novel pipe oxygenation aerating apparatus, belongs to water-treatment technology field.

(2) background technology

The existing pond oxygenation aerator that is used for has two kinds of patterns usually, a kind of is mechanical surface aeration oxygen replenishing equipment, this mechanical surface aeration oxygen replenishing equipment is positioned at wheel rotation on the water surface by driven by motor to be splash spray and contacts with air, makes oxygen soluble in water, to reach the purpose of oxygenation.Though the oxygenation aerator of this structure formation has the good advantage of oxygenation effect, structure is comparatively complicated, and cost is expensive, keeps in repair cumbersomely, and floor space is big, and noise is serious.Another kind is a tubular type oxygenation aerator, it is made up of institutes such as motor, air compressor machine (or air pump), pneumatic tube, aeration tubes, produce pressurized air by air compressor machine or air pump and pass through pneumatic tube, and by the ejection of the nozzle of aeration tube, make airborne oxygen contact and be dissolved in water with water, to reach the purpose of aeration oxygen replenishing.Though this tubular type oxygenation aerator has advantage simple in structure, that cost is low and easy to use, but because its aeration tube is arranged at the final position that oxygenation aerator and water directly contact, therefore, the reasonableness of its structure will directly have influence on the every performance index and the work-ing life of oxygenation aerator.And use the shortcoming of the maximum that this tubular type oxygenation aerator exists to be at present: 1), the aeration tube unreasonable structure, the backwater plugging problem that exists, and accelerated the corrosion of water to aeration tube, thus seriously influenced the work-ing life of oxygenation aerator; 2), the installation, maintenance of aeration tube is comparatively complicated.The existence of these problems not only directly has influence on promoting the use of of tubular type oxygenation aerator, and directly has influence on the result of use and the work-ing life of tubular type oxygenation aerator.

(3) summary of the invention

In view of the problem of above-mentioned existence, the purpose of this utility model provides that a kind of rational in infrastructure, simple installation, performance are good, a kind of novel pipe oxygenation aerating apparatus of long service life.

Summary of the invention of the present utility model is: improve the structure of final parts one aeration tube that tubular type oxygenation aerator and water directly contacts, with insoluble backwater and etching problem in the use of thorough solution aeration tube.

Concrete technical measures of the present utility model are: the parent tube outside surface at aeration tube adds one deck periosteum, and offers aerating pore on periosteum; The material of periosteum adopts rubber-like rubber to make, because the elasticity that rubber itself is had, make and to be arranged at periosteum aerating pore on the aeration tube parent tube under the effect of air pressure, function with check valve is promptly when air compressor machine is worked, when the pressurized air that air compressor machine produced transfers to aeration tube by pneumatic tube, between aeration tube parent tube and periosteum, form a cavity, and produce certain air pressure, thus make the periosteum aerating pore on the aeration tube parent tube open, and carry out aeration equably; When air compressor machine quits work, air pressure in the cavity that forms between aeration tube parent tube and the periosteum disappears, periosteum aerating pore on the aeration tube parent tube is under the effect of hydraulic pressure, the periosteum micropore is closed automatically, thereby thoroughly solved the problem of aeration tube backwater plugging, and, also solved water for aeration tube corrosive problem owing to realized aeration tube and water are isolated.

Advantage of the present utility model:

1, be skillfully constructed, simple and reasonable for structure, installation, maintenance is convenient.

2, production cost is low, long service life.Because thoroughly solved backwater plugging that aeration tube exists and the water problems such as corrosion to aeration tube, more traditional tubular type oxygenation aerator has improved more than the several times its work-ing life.

(5) embodiment

A kind of novel pipe oxygenation aerating apparatus includes parts such as air intake branch 1, inlet pipe 2, variable micropore aeration pipe 3; Inlet pipe 2 is connected with air intake branch 1 by tube stub, and variable micropore aeration pipe 3 is connected with inlet pipe 2 by gas-distribution pipe 11, flange 12, packing ring 14,15; Pipe close 10 is arranged at the end of variable micropore aeration pipe 3, to prevent to manage interior water inlet; Outside surface at the parent tube 4 of variable micropore aeration pipe 3 is provided with one deck periosteum 5, on periosteum 5, is provided with aerating pore 6; Periosteum 5 adopts whippy elastomeric material to make, and the thickness of periosteum 5 is being the best between the 1.5mm-3.5mm; The diameter that is arranged at the aerating pore 6 on the periosteum 5 is best with 1.5mm-2.5mm.On gas-distribution pipe 11, be provided with ventilating pit 13; Be connected the radially position of an end with gas-distribution pipe 11 at the parent tube 4 of variable micropore aeration pipe, be provided with air inlet port 8; Thereby make between inlet pipe 2 and gas-distribution pipe 11 and variable micropore aeration pipe parent tube 4 and the periosteum 5, constitute the path of a ventilation.For guaranteeing that variable micropore aeration pipe has corresponding strength and rigidity, the parent tube 4 of variable micropore aeration pipe can adopt galvanized pipe or ABS material to make.

Flange 12 and gas-distribution pipe 11 are interconnecting pieces of variable micropore aeration pipe 3 and inlet pipe 2.Gas-distribution pipe 11 can adopt stainless steel tube, galvanized steel pipe or ABS material to make, and at gas-distribution pipe 11 two ends, is provided with the installation screw thread; The curved structure of end face that flange 12 is connected with inlet pipe 2, its radian is identical with the external diameter of inlet pipe 2, like this, both can guarantee to have the excellent contact surface between the two, can guarantee to have good strength of joint between the two again.

Variable micropore aeration pipe 3 generally gathers in the bottom of aeration tank, and its length size is decided on the length size in pond.Be advisable for about 10-30 centimetre at the bottom of the surface distance pond of variable micropore aeration pipe 3.During installation, on inlet pipe 2, bore earlier the hole that can pass gas-distribution pipe 11, and gas-distribution pipe 11 is passed in the hole of inlet pipe 2, and in variable micropore aeration pipe 3, load onto sealing-ring 7, then by the screw thread on the connecting joint on flange 12, packing ring 14,15 and the variable micropore aeration pipe 3, with its both sides that are installed in inlet pipe 11, get final product.Its shape then can be different with the shape in pond, and the installation form of its variable micropore aeration pipe can be that rectangle, square, circle or ellipse etc. are not limit.

Novel pipe oxygenation aerating apparatus in use, its air intake branch 1 can be connected by the source of the gas of flexible pipe with air pump or air compressor machine one class.At this moment, air through overdraft is entered in the inlet pipe 2 by air intake branch 1, and enter the inner chamber of gas-distribution pipe by the ventilating pit on the gas-distribution pipe 11 13, the intake work hole 8 of inner chamber on variable micropore aeration pipe parent tube 4 from gas-distribution pipe, enter between variable micropore aeration pipe parent tube 4 and the parent tube periosteum, form an air pressure cavity, thereby make the periosteum aerating pore 6 on the variable micropore aeration pipe parent tube 4 open, and carry out aeration equably; When air compressor machine quits work, air pressure between variable micropore aeration pipe parent tube 4 and the periosteum 5 in the formed cavity disappears, periosteum aerating pore 6 on the variable micropore aeration pipe parent tube 4 is under the effect of hydraulic pressure, periosteum micropore 6 is closed automatically, thereby thoroughly solved the problem of aeration tube backwater plugging, also solved water for aeration tube corrosive problem simultaneously.
