Abstract
The utility model relates to an aeration device, particularly an energy-saving impeller aeration pump, which comprises a pump base, a pump casing positioned on the pump base and a pump shaft arranged in the pump casing, wherein an impeller is connected with the pump shaft, an inlet of the impeller is provided with an aeration nozzle and a gas suction is positioned on a water suction opening of the pump. The utility model has multiple functions and can convey water which waits to be treated or returned activated sludge, and aeration can reoxygenate to the conveyed water which waits to be treated or the returned activated sludge. The utility model has the advantages of big aeration capacities, few used special aeration machines and electrical devices, high aeration capacities, high effects, simple structure, convenient operation and use, etc., building area occupation is reduced and the utility model is an ideal aeration device.
Description
Technical field
The utility model relates to a kind of aerator, particularly relates to a kind of impeller type energy-saving and aerating pump.
Background technique
In the process of Sewage Biological Treatment and underground water deferrization and demanganization, all need water is carried out aeration to quicken the process of oxygen by gas phase mass transfer in water.At present, the aeration method of domestic and international application (1) bubble aeration method.(2) jet-flow aeration method.(3) trickle aeration.(4) impeller type or rotary-brush type surface aeration method.(5) contact-type aeration tower aeration.(6) drop water aeration method etc.And use more method is bubble aeration method and impeller surface aeration method.These aeration methods all need the special-purpose first-class facility of aeration machinery, pipeline, aeration.Their power consumptions are big, the aeration weak effect, occupy the machinery and the electrical equipment of certain space, needs special use.
Summary of the invention
The aeration ability that goal of the invention of the present utility model provides a kind of specific energy consumption is big, and it is few to account for building area, the impeller type energy-saving and aerating pump that aeration is effective.To overcome background technique aeration weak effect, take many drawbacks such as space.
Realize that foregoing invention purpose technological scheme is: comprise pump seat, be positioned at the pump case on the pump seat, place the pump shaft in the pump case, its structure outline is, impeller is connected with pump shaft, and the inlet of impeller is equipped with aeration and chews, and intakeport is positioned on the water sucking mouth of pump.
Owing to adopted technique scheme, this device one-machine-multi-function can be carried pending water or returnedactivatedsludge, and aeration is reoxygenation in pending water that is transferred or returnedactivatedsludge.Aeration ability with specific energy consumption is big, reduces to account for building area, and the special-purpose aeration machinery and the electrical equipment of use are few, aeration ability and effect advantages of higher.This apparatus structure is simple in addition, and is easy for operation.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
The utility model is made up of impeller 1, pump case 3, pump seat 4, pump shaft 5 etc.Referring to accompanying drawing 1,3 of pump cases are on pump seat 4.Pump shaft 5 is installed in the pump case 3, and impeller 1 is installed on the pump shaft 5 and is connected with pump shaft 5, and the inlet of impeller 1 installs a plurality of aerations and chews 2.Impeller 1 is the impeller of centrifugal pump, mixed flow pump and axial-flow pump.
Referring to accompanying drawing 2, the intakeport 7 of wing pump is arranged on the pump water sucking mouth 8 and is communicated with water sucking mouth 8.Also it can be arranged on the suction line of pump according to designing requirement.On.
Working principle of the present utility model: the external force moment of torsion orders about impeller 1 rotation by pump shaft 5 and produces power, and the gas-liquid two-phase mixed medium in impeller 1 inlet is moved to outlet by the import of impeller 1, and the import of impeller 1 is a negative pressure state, exports to be barotropic state.Liquid enters impeller 1 by intakeport 7.Air is chewed 2 by aeration and is entered impeller 1 and mix with liquid, and supercharging gradually.When arriving the spiral case inner chamber of impeller 1 outlet port and pump casing 3, reach pressure maximum.Enter in the head conduit by setting-out mouth 6 subsequently.Air is chewed 2 by aeration and is entered impeller 1, is dialled to cut by the blade of impeller 1 to form atomic little bubble, causes the great mass transfer environment of specific surface.Under the effect of the partial pressure of oxygen, airborne oxygen by mass transferring in gas phase in liquid phase.Variation according to the revolution of pump shaft output: or the variation in pressure of pressure tube; Or the variation in pressure of pump import and export.Reduce to import the power of pump shaft,, finish the overall process of aeration to reach the purpose of energy-saving and aerating.
Claims (1)
1, a kind of impeller type energy-saving and aerating pump comprises pump seat, is positioned at the pump case on the pump seat, places the pump shaft in the pump case, it is characterized in that impeller is connected with pump shaft, and the inlet of impeller is equipped with aeration and chews, and intakeport is positioned on the water sucking mouth of pump.
