Description
Technical field
The utility model belongs to the environmental protection equipment field, relates to the aerator that a kind of sewage carries out biochemical treatment, is specifically related to a kind of aerator under water.
Background technology
Along with the raising of Chinese economic development and people's lives, living environment is more and more paid attention to by people, thus nearly more than ten years all parts of the country all building the water resource environment of various sewage works with protection China, ensure people's safe drinking water.Oxidation ditch process in the method for sewage disposal and technology is because its management is simple, strong shock resistance, ideal treatment effect and being widely used.Key equipment in oxidation ditch process is disposed of sewage is an aerator.The aerator that is adopted in this technology has the inversed umbrella type aerator at present, the brush aeration machine, plate-spinning aerator etc., and these aerators can only be installed on the water surface, cause oxygen-transfer efficiency low, equipment volume is huge, and be furnished with a lot of parts and form, powerful step-down gear must be equipped with particularly all, its cost is very high, the different damage of complex structure, maintenance load is big.And motor placed the ubiquity noise is big on the bank, influence peripheral resident, the energy consumption height, efficient is low, treating water is more shallow, floor space is big wait not enough.
Summary of the invention
The purpose of this utility model is in order to overcome the above-mentioned deficiency of prior art, and a kind of aerator under water that 4～6 meters degree of depth are carried out oxygen uptake and aeration that can be put under water is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of aerator, the aeration chamber, inlet pipe, the guide shell that comprise motor, motor shaft, impeller, both ends open, impeller is positioned at inside, aeration chamber, aeration chamber skin is provided with a urceolus, urceolus and aeration chamber wall and steel plate surround the ring-type air collecting chamber of two sections sealings jointly, and the aeration chamber wall part corresponding with air collecting chamber spreads all over qi-emitting hole.
Be provided with the disc type hollow form porous crushing shell of the densely covered aperture of plate face in the described air collecting chamber between aeration chamber wall and the urceolus.
Described porous crushing shell is vertical with aeration chamber wall.
The quantity of described porous crushing shell is more than 1 or 1.
The qi-emitting hole of described aeration chamber wall and the hole shape on the porous crushing shell are circular, square, trilateral or other geometrical shapies, and the aperture is 2～60mm.
Motor places under water, links to each other with impeller by motor shaft, so that kinetic energy is passed to impeller.
Described impeller is made up of 3～4 propeller blade shape blades, is vortex shape, and diameter is 150～1000mm.The less water screw of diameter dress blade helps producing stronger negative pressure, and not only aeration quantity is big, and power consumption is low, and vanelets high speed rotating under driven by motor, can produce more powerful seismic wave, and cutting, crushing effect are better.
Described inlet pipe is vertical with horizontal plane, and the water surface is stretched out on its top, and the bottom communicates with air collecting chamber, and inlet pipe top is provided with air volume regulating valve.
Described guide shell is a telescoping, is welded on one or both ends, aeration chamber.
The export orientation mouth flare of described guide shell, taper or directly barrel-shaped, preferably tubaeform.Flaring targeting port can enlarge flow plane, makes water aeration flow through the whole aeration tank of cloth, avoids producing the dead angle.
Described targeting port is provided with two guide plates longitudinally, and the distance between two guide plates can be regulated according to concrete needs.
Described motor is a frequency control motor, regulated at will rotating speed between 0～2800rpm as required, and described motor also can be standard electromotor.
Described aerator under water is installed on the liftable sliding support, can carry out lifting as required and reach best result of use.
The beneficial effects of the utility model:
The utility model motor and aeration unit of aerator under water all places under water, and noise is low, only needs short motor shaft impeller, has greatly reduced cost and power consumption, and can slip at the bottom of the darker pond, handles the depth of water and can reach 6 meters.
Impeller produces powerful negative pressure seismic wave and rotary-cut power in the rotation of aeration chamber high speed, air is sucked air collecting chamber by inlet pipe, the air that enters air collecting chamber under the effect of seismic wave and rotary-cut power during through the qi-emitting hole of porous flinders and aeration chamber wall air bolus and air chain shredded, impeller cut, fragmentation, the mixing of rotating again through aeration chamber high speed, make it broken dramatically and also fully be dissolved in the water, significantly improved aeration efficient; Qi-emitting hole is dispersed throughout the air collecting chamber endless inner wall, makes inhaled air be rotated the cutting mixed aeration by the comprehensive supply impeller of 360 degree, also plays the effect that significantly improves inspiratory capacity and aeration efficient, and inspiratory capacity can reach 400～600m
3/ h need not to be equipped with separately gas blower, and the utilization ratio of oxygen can reach 60%～90%, has reached the purpose of giving the high oxygenation of pond water.Because the qi-emitting hole of porous flinders and aeration chamber wall to the preliminary fragmentation of air, has been saved power consumption, reduced working cost simultaneously.
Because the utility model aeration machine impeller is less, required rotating speed is higher during works better, generally more than 1000rpm, directly provide kinetic energy to get final product by frequency control motor or standard electromotor, do not need to dispose separately step-down gear, both reduced cost, overcome the defective of step-down gear inconvenient maintenance again.
Inlet pipe top is provided with air volume regulating valve, but Open valve is air-breathing by it when needing the oxygen supply aeration in aeration process, when needing anoxic or anaerobism in the water, just valve is turned off and stopped air feed and make impeller in water, carry out plug-flow and stirring in the running, reach the purpose of a tractor serves several purposes.
In sum, this aerator is simple in structure, and volume is little, and equipment investment cost is low.Be positioned under water, need be equipped with gas blower, noise is little.Porous flinders and the existence that spreads all over the aeration chamber wall of qi-emitting hole, the seismic wave that produces with the impeller high speed rotating complements each other, air can very big degree be broken, inspiratory capacity and aeration efficient significantly improve, saved power consumption, having reduced working cost, is to utilize oxidation ditch process various industrial sewages and city domestic sewage to be carried out the key equipment of biochemical treatment.This equipment also can be used for the improvement of lake and city river sewage.
