Technical field
The utility model belongs to the environmental protection equipment field, relates to a kind of oxidation ditch process that utilizes to the aerator that sewage carries out biochemical treatment, is specifically related to a kind of aerator.
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., these equipment volume are huge, need a lot of auxiliary accessories or device, deficiencies such as floor space is big, and the step-down gear that existing all aerators all need be large-scale, and equipment manufacturing cost height and maintenance load are big.It is the noise that reduces aerator that part producing producer is also arranged in recent years, has researched and developed aerator under water, and aeration unit and motor are all placed under water.Just can carry out aeration but this aerator under water need be equipped with the air blast air intake equipment, electrical fault is many, and the life-span is shorter, and maintenance difficult, expends a large amount of manpower and materials.
Summary of the invention
The purpose of this utility model is in order to overcome the above-mentioned deficiency of prior art, a kind of other utility appliance that need not to be provided, and volume is little, and aeration is effective, can carry out the aerator of oxygen uptake and aeration to 4～6 meters degree of depth under water.
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.
Described motor places on the water surface, motor shaft (2) vertical and horizontal face, and mainly the aeration unit of being made up of impeller, aeration chamber, air collecting chamber, inlet pipe, guide shell places under water, keeps 0～20 ° of angle with horizontal plane; The degree of depth is more shallow when the aeration tank, and when described aeration unit can go deep at the bottom of the pond, the angle of aeration unit and horizontal plane can be set to 0 °; As aeration tank dark (6m or more than the 6m), when described aeration unit can not go directly at the bottom of the pond, the angle of aeration unit and horizontal plane is made as greater than 0 ° of acute angle smaller or equal to 20 °, this moment, aeration unit was horizontal by certain angle, has very strong plug-flow effect, make at the bottom of the through pond of aeration water body, help large-area water circulation simultaneously and flow.
Motor shaft links to each other by angle umbrella shape transmission joint with the slurry axle of impeller, so that the kinetic energy of motor shaft is passed to impeller.
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.
Described impeller is made up of 3～4 propeller blade shape blades, is vortex shape, and diameter is 150～1000mm.The less water screw dress blade of diameter helps producing stronger negative pressure, and not only aeration quantity is big, and power consumption is low.
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 outlet of described guide shell is provided with the targeting port of 1～3 different directions, and targeting port flare, taper or directly barrel-shaped are preferably tubaeform.The tubaeform targeting port of different directions 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 aeration unit 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 impeller of the utility model aerator 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 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 very big degree and shredded and 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.
The utility model motor places on the water surface, and aeration unit is as under water, and motor housing is not had the requirement of high leakproofness, has reduced cost, has overcome simultaneously that the submersible machine fault is many, the life-span short, the defective of inconvenient maintenance.
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.
The utility model aerator 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.
The utility model aerator is simple in structure, and volume is little, and equipment investment cost is low, is to utilize oxidation ditch process various industrial sewages and urban domestic wastewater 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.
