Description
Technical field
The utility model relates to a kind of aerating apparatus that waste water is handled, and particularly relates to a kind of submersible high-efficiency energy-saving mixing aeration device that self-priming and blast aeration combine that stirs.
Background technology
Energy-saving and emission-reduction are one of fundamental state policies of China's socio-economic development.Along with deeply carrying out of this fundamental state policy, the industrial sewage of China, municipal effluent have obtained rapid improvement, and the quantity discharged of water pollutant (COD) descends year by year, and recycling economy further develops.Be accompanied by the reinforcement of water environment protection dynamics, be used for the aerating apparatus of the biochemical aerobic unit of wastewater treatment, make rapid progress, flourish.Current, in wastewater treatment, generally the main aerating apparatus of Cai Yonging has following several.
1, high-power inversed umbrella type surface aeration machine: under the powerful prograding of inversed umbrella type impeller, water is the water curtain shape and throws away from the impeller edge, forms water curtain, wraps up in into a large amount of air; Because sewage circulates up and down, bring in constant renewal in liquid level, the sewage big area contacts with air; The impeller rotation drives water body and flows, and forms negative pressuren zone, sucks air, and airborne oxygen dissolves in rapidly in the sewage, finishes the oxygenation to sewage, and then accelerates the scavenging process of sewage.Simultaneously powerful power wheel drive is stirred a large amount of water bodys and is flowed, thereby realizes pushing away the wave effect.Its weakness is that power consumption is bigger, and control owes flexible.As impeller diameter D (mm) 4000 models, power of motor is 132Kw, and oxygenation capacity (KgO/h) is 284.
2, suspension type aerating apparatus: the notable feature that it is different from other aeration process is: above gas transmission (distribution) pipeline is suspended in; Suspension chain is connected with aerator, aerator with do not have any contact that is connected at the bottom of the pond, rely on suspension chain to suspend in water, can move freely.This technology is very low to the structural requirement of aeration tank, helps reducing the construction investment of sewage disposal; When aerator damages, can not cut off the water, not stop under the situation of air feed, taking advantage of canoe to pull it out water surface maintenance and replacing.Its weakness is that the diaphragm aerator easily stops up, and produces the aeration aerating deficiency, and biochemical clearance descends.
3, efflux aerator: this device is to utilize the fluidics principle, and the air that gas blower is sent here mixes in ejector with sewage, and oxygenation is in sewage; For sewage is flowed in biochemical Aerobic Pond, the exchange interface need be aided with the effluent cycle system.Its weakness is: power consumption is bigger, and ejector will not keep in repair in water.
The performance of the above-listed main aerating apparatus that generally adopts cuts both ways.
Summary of the invention
The purpose of this utility model be to overcome the weakness of existing aerating apparatus and provide a kind of and do not have obstructions, be convenient to regulate, oxygen transfer efficiency height, simple installation, the submersible high-efficiency energy-saving mixing aeration device that keeps in repair easily.
The purpose of this utility model is achieved in that and comprises the base assembly, is installed in air channel body in the base assembly, is installed in the disc seat on the base assembly, it is characterized in that:
Base assembly, air channel body and disc seat are connected to one-piece construction, the inside of base assembly be and the external world between the aqueous vapor that guarantees that is connected carry out blended stator passage;
On disc seat, be fixed with sealing cover, between sealing cover and the disc seat for being tightly connected, reducing motor is installed in sealing cover, reducing motor is fixed on the disc seat, the output shaft of reducing motor passes disc seat and is connected with the wheel rotation axle, be fixed with disk of conical profile on the wheel rotation axle, the stator passage that disk of conical profile is arranged in base assembly inside becomes rotor, and the mechanical seal of Wimet high-seal is installed between the output shaft of reducing motor and the disc seat;
On the base assembly inlet pipe is installed, this inlet pipe is connected with the air channel body that is installed in the base assembly, and corresponding disk of conical profile offers the air outlet on the body of air channel.
The pressure air that is come by gas blower is input to inlet pipe after the steam line metering, enter the air channel body then, on the air outlet of offering on the body of air channel, air distributor is installed, pressure air enters disk of conical profile through air distributor, the disk of conical profile high speed rotating constantly promotes water, gas and active sludge high efficient mixed in the aeration tank.
On reducing motor, be equipped with and the extraneous oily temperature radiator that is connected.
On the conical surface of disk of conical profile, have some weep holes.
The utlity model has following positively effect:
The utility model adaptation trade effluent, municipal wastewater are handled, adaptability is very extensive.It has the oxygen transfer efficiency height, and is energy-saving and cost-reducing; Do not have and stop up, operate steadily; Install fast and conveniently, the aeration tank need not emptying; Equipment can arbitrarily move and promote, and for ease of maintenaince waits advantage.Remedied the deficiency of some aerator effectively.
1, deep water is arranged: because the submersible machine superior performance of band wheel casing adopts the deep-water motor packing technique, aerator is arranged vertically, can reaches 20m deeply at Shui Zhongchi.Because of the depth of water can make air residence time in water long, so temperature equalisation under water is the oxygen transfer rate height.
2, aeration is stable: the impeller aerating system of being made up of oxygen system and high-speed stirring, its oxygenation capacity, finish by air inlet and water thorough mixing function, if control well gas-vapor mix than and wind supply quantity, can reach the aeration performance of required best continous-stable.Work water surface visible bubble in bubble is closely knit evenly.Simultaneously, the negative pressure that impeller forms under high-speed motion state has also increased the self-suction function of this machine, the supply gas pressure of gas blower can correspondingly be reduced, thereby further improved the dynamic efficiency of complete machine.
3, stir anti-heavy: it is an aerated mixing plant at the bottom of a kind of pond, utilizes open blade wheel structure design, does not only have the sorrow of obstruction, and can effectively prevent mud sedimentation and the generation of anaerobism phenomenon at the bottom of the pond.
4, flexible for installation: it is the energy-efficient stirring aerator that integrates mechanical ﹠ electrical technology and biochemical technology, is the desirable substitute products of traditional aerator.This machine relies on from reorientation in the aeration tank.Incorporate hoisting Design need not any utility appliance, arranges very flexible.Need not draining and do not interrupting realizing fast hoisting under the situation of normal process operation; Not changing under the biochemical aeration tank structural condition, finish renovating of aerator fast, improve aerobic biochemical usefulness.
5, reduce expenses: it not only has the characteristics of energy-efficient consumption reduction, and it also has characteristics such as construction investment is few, easy and simple to handle, and operation and maintenance cost is low.
