Technical field
The present invention relates to a kind of sewage disposal device, be specifically related to self-priming centrifugal submersible aerator.
Background technology
Self-priming centrifugal submersible aerator is a kind of for the specific equipment to the water body aeration aerating in water technology.Its principle of work is: the submersible machine transmission shaft directly drives and is built in the semiclosed-type impeller high speed rotating in aeration plate, under the effect of rotary blade centrifugal force, produces high pressure, and air and water are inhaled into from the inlet mouth of aeration plate upper/lower terminal respectively; Impeller communicates with passing into inlet pipe waterborne, imports air.The aeration plate surrounding is furnished with a plurality of runners, the radially ejection at a high speed from exit after water, gas mixed solution enter in runner and fully mixed, and to surrounding, spread rapidly, micro-bubble in small, broken bits fully with pond in the water body fusion, oxygen in atmosphere is dissolved in the water, thereby reaches to the purpose of water body aeration aerating.
The negative pressure air amount that this kind of aerator produces due to by the vane rotary draining time, do not need to configure blast apparatus, and the equipment facility investment is few, therefore extensively in sewage treatment process, is used.But there is following defect in this kind of aerator used at present:
When 1, aerator is worked, air is to be inhaled into the impeller intraperitoneal by inlet pipe from the impeller axle center hole, because motor is to be placed on the aeration plate top, and coaxial with impeller, make inlet pipe to dock with the axle center hole of impeller top.For head it off, the intake method of aerator has two kinds of structure formations at present: the one, and inlet pipe curves 180 degree and enters from the axle center hole of impeller below; The 2nd, a middle gas chamber is set above mixing chamber and between submersible machine, with inlet pipe, communicate, the hole of middle gas chamber below communicates with the impeller axle center hole, and air is imported.
The defect that these two kinds of structures are deposited is: produce addedresistance when high-speed air process channel bend or air chamber, cause air-intake negative-pressure loss of pressure head, air input reduces, and has reduced the aeration efficiency of aerator.
2, the runner of aerator mixing chamber surrounding is the distribution of horizontal dispersion shape, and when work, water, gas mixed solution are from exporting also along continuous straight runs ejection.During installation, in order to make pool bottom sludge, do not precipitate, aerator is placed at the bottom of need being close to pond, and aerator water-in and runner are easily stopped up by the foreign material in mud like this, easily causes impeller to damage.Although slag net has been installed in the aerator water inlet by some producers, slag net also can be stopped up by the fibre object in water, causes the aerator aeration rate even cisco unity malfunction that descends.
3, aeration plate is a plate-like foundry goods, and middle cavity is placed impeller, and many runners of surrounding distribution communicate with it, and runner exit is on the aeration plate circumferential edge, and during aeration, the aeration plate periphery can form an annular bubble band.A large amount of small bubbles in annular bubble band can become large because not spreading in time to merge rapidly, and bubble surface area is sharply reduced, and cause the dissolved oxygen efficiency of water to descend.Simultaneously, along with the change of single isolated bubbles diameter is large, its buoyancy in water increases, and has accelerated the lift velocity of bubble, has reduced the residence time that gas ducks in drink, and has also caused the dissolved oxygen efficiency of water to descend.
Summary of the invention
Main purpose of the present invention is to provide a kind of centrifugal submersible aerator of high-efficiency self-suction of reliable operation.
For achieving the above object, the technical solution adopted in the present invention is: a kind of submersible aerator, the transmission shaft that comprises submersible machine connects the impeller that is positioned at the aeration plate inner chamber, the aeration plate upper end arranges inlet mouth, lower end arranges water-in, the aeration plate periphery arranges water, gas mixed solution is entered to the runner in water, it is characterized in that: the oblique lower setting of the runner of described aeration plate periphery.
