Description
Technical field
The utility model relates to a kind of waste disposal plant, and more particularly, it relates to the good aeration agitation all-in-one of a kind of result of use.
Background technology
Aerator is used for waste water Wastewater Treated by Activated Sludge Process process, mainly provides oxygen to aeration tank.Mechanical type aerator due to easy to maintenance, use reliable, cost of investment is low, can not produce the attention that the secondary pollutions such as noise are more and more subject to environmental protection circle.In actually operating, in order to the oxygen accelerated in air shifts in liquid, mechanical type aerator, except suction air, also needs agitated liquid, the liquid-to-air in pond is fully contacted, reaches high efficiency oxidation effect.In order to improve microorganism in the organic sludge at the bottom of pond, waters and combination with oxygen further, aerator is needed to be arranged on alap position, and then the microorganism in guarantee mud is having under sufficient oxygen, carries out oxygenolysis, reach good treatment effect to organism.But due to the restriction by air pressure, the mechanical type aerator on existing market, the service degree of depth in sewage lagoon is very limited, and the service depth of water of high-power aerator is the most also no more than 5 meters, and the service depth of water of small power aerator is more shallow.Underwater penetration is deepened, and the air capacity of suction can reduce, and processing power reduces.Even degree of depth that can be such, in some large-area waters, the oxygen that aerator is brought into also cannot arrive all positions at the bottom of pond completely, also just fully cannot contact with the microorganism in mud.And at present along with the raising of land utilization ratio, pond can be found everywhere more than the aeration tank of 5 meters deeply.So existing mechanical type aerator can not meet actual demand, and use range is very limited, anxious to be modified.
Chinese patent notification number CN203128292U, disclose a kind of guide-vane submersible aerator, it is fixed on bottom aerated reaction pond by support, it is made up of aerator main body, axle, guide bearing, impeller, mixing section, guide vane and nozzle, two impellers are connected on aeration arbor, each impeller is Three-blade structure, and guide vane is arranged in nozzle.The aerator of this structure is more shallow in the working depth of sewage lagoon, and processing power is lower, and oxygen-transfer efficiency is low.
Utility model content
It is more shallow that the utility model overcomes existing aerator working depth, processing power is lower, the deficiency that oxygen-transfer efficiency is low, provide a kind of aeration agitation all-in-one, its working depth is darker, working depth scope is wide, processing power is strong, and oxygen-transfer efficiency is high, uses easy to operate, use properties is good, the failure rate is low of equipment.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of aeration agitation all-in-one, comprise power submersible machine, speed reduction unit, aerating apparatus, power output shaft is provided with in power submersible machine, power output shaft upper, the upper of power submersible machine is stretched out at lower two ends respectively, lower two ends, lower end and the speed reduction unit of power output shaft are in transmission connection, the output shaft of speed reduction unit is in transmission connection agitating vane, upper end and the aerating apparatus of power output shaft are in transmission connection, the upper end of aerating apparatus is fixedly connected with mounting sleeve, aerating apparatus comprises trash rack, negative pressure seat, circulation channel, trash rack sidewall is provided with water-in, aeration impeller is provided with in negative pressure seat, the upper end of aeration impeller and power output shaft is in transmission connection, in negative pressure seat, the top of aeration impeller is provided with gas skirt, gas skirt upper end connects inlet pipe, circulation channel being laid with several for what discharge air-water mixture goes out circulation road, go out circulation road outward-dipping setting from top to bottom.
After power submersible machine starts, aeration impeller high-speed rotation is driven by power output shaft, negative pressure is produced near aeration impeller water-in, liquid ceaselessly sucks by negative pressure on the one hand, by inlet pipe, the air on face, pond is ceaselessly sucked aeration impeller water inlet position on the other hand, liquid and the air of suction are pulverized through aeration impeller, mix in circulation channel, finally form microbubble to pass through circulation road and be discharged in the sewage of certain depth, and by the antimicrobial absorbent in sewage.Power output shaft lower end drives agitating vane to rotate with slower speed by speed reduction unit, rotating at a slow speed of agitating vane produces very large impellent, this impellent promotes agitating vane and moves at the bottom of pond with the liquid of lower part, encounter at the bottom of pond and spread to surrounding, final arrival topmost surface, and to center flow, the aerating apparatus being then placed on not only central zone ceaselessly sucks after oxygenation but also from going out circulation road discharges, and forms circulation.This addresses the problem the oxygenation problem of the following partial sludge in exhaust-duct.Therefore this vibrational power flow can make aeration agitation all-in-one position very dark in pond also can normally work, and reaches good treatment effect.That so just aeration tank can be done is very dark, under the same residence time, greatly reduces the area of aeration tank, reduces the floor space of aeration tank.Aeration agitation all-in-one working depth is comparatively dark, and working depth scope is wide, and processing power is strong, and oxygen-transfer efficiency is high, uses easy to operate, and use properties is good, the failure rate is low of equipment.
As preferably, gas skirt is downward opening bowl structure, and inlet pipe lower end is connected on the upper surface of gas skirt, and the upper end open of inlet pipe exposes pond liquid level.The gas skirt gas collection of this structure is effective, gas-liquid can be made fully to contact mixing, considerably increase oxidation effect.
As preferably, the width going out circulation road inner chamber reduces gradually outward in upper.Going out circulation road can be that gas-liquid mixture is discharged rapidly.
As preferably, all by flange compact siro spinning technology between trash rack and negative pressure seat and between negative pressure seat and circulation channel, power submersible machine upper end is fastenedly connected with sealing socket by flange, be provided with the pilot hole for connecting positioning power output shaft in the middle of sealing socket, the lower end adaptation of circulation channel to be overlapped on sealing socket and power submersible machine upper flanges, sealing socket, circulation channel three to be fastened together by screw.Sealing socket serves the effect of location to power output shaft, and make power output shaft steadily reliable in the process of rotating, between power submersible machine and circulation channel, connect sealing socket, connect steadily, strength of joint is good.
As preferably, power output shaft upper end and and aerating apparatus between and be equipped with mechanical seal between power output shaft lower end and speed reduction unit.Mechanical seal good sealing effect.
Compared with prior art, the beneficial effects of the utility model are: aeration agitation all-in-one working depth is comparatively dark, and working depth scope is wide, and processing power is strong, and oxygen-transfer efficiency is high, uses easy to operate, and use properties is good, the failure rate is low of equipment.
