Abstract

The utility model relates to an aeration water treatment appliance, which solves defects of complicated appliance structure, high cost, inconvenient maintenance, etc. existing in a background art air blowing underwater bubbling aeration appliance and a mechanical type surface aeration appliance. The main technical characteristic is that a power shaft of an electric motor drives a hollow rotation shaft, a sleeve pipe is sleeved at the outer side of the hollow rotation shaft, a hollow rotation shaft part which is exposed out of a water surface is provided with an air inlet which is communicated with atmosphere, an impeller shaft which is connected with the bottom end of the hollow rotation shaft is provided with an air outlet, and the impeller shaft is provided with an impeller. The utility model can be widely used for water treatment aeration process, having the advantages of simple structure, low cost and no water spatter.

Description

A kind of aerator of impeller under water

The utility model relates to a kind of water treating equipment, particularly a kind of water aeration treatment facility.

In the background technology, the water aeration treatment facility generally is such two kinds of forms: a kind of is blowing-type bubbling aeration under water, promptly produces in the air nozzle of pressurized air input water basin with air compressor machine to spray, and airborne oxygen is contacted with water and is dissolved in the water.Though this aeration mode dissolved oxygen effect is good, the device structure complexity, involve great expense, keep in repair loaded down with trivial details, floor space is big, noise is serious.Another kind is the mechanical surface aeration, is positioned at wheel rotation on the water surface by driven by motor and splashes spray and contact with air, makes oxygen soluble in water.The equipment of this structure formation exists complex structure, expensive problem too, and running noise is little though the water surface stirs strong, and the amplitude that dabbles is bigger, and surrounding devices is frozen, and is not suitable for northern area and uses.

The purpose of this utility model is exactly the aerator that proposes a kind of aeration mode under water, to solve the existing defective of background technology.

The technical solution of the utility model is achieved in that a kind of aerator of impeller under water, motor is fixed on the bearing, the power shaft of motor drives hollow rotating shaft, the telescopic two ends of hollow rotating shaft periphery connect with bearing and supporting sleeve respectively, hollow rotating shaft surface the part be provided with some can with the anastomosing air inlet port of atmosphere, the hollow rotating shaft bottom connects impeller shaft, sets out pore on the impeller shaft, connects impeller on the impeller shaft.Wherein, bearing is the unenclosed construction that communicates with atmosphere; Impeller is that upper and lower end plate and the impeller blade between it are formed; Connect with universal coupling between motor power axle and the hollow rotating shaft.

The utility model is compared with background technology and is had the following advantages and positively effect.Because electric motor drives impeller high speed rotating under water by hollow rotating shaft, form negative pressure at the back side of radial vane, air advances impeller shaft by air inlet port by hollow rotating shaft, and ejection discharges on the production well of impeller shaft, forms bigger air filled cavity.Enter in the water, the impeller cut by high speed rotating becomes a small air material again, has improved the surface-area of unit volume air, and it is soluble in water that airborne oxygen sees through gas-water table, thereby improves dissolved oxygen amount.The rotation of impeller drives current simultaneously by the mobile turbulent flow that forms of certain orientation, and it is strong that water is stirred.So just do not need air compression and handling equipment, the phenomenon that do not dabble again, thus overcome the defective of two kinds of equipment in the background technology.On the other hand, this utility model is simple in structure, and cost is low, and is easy to maintenance, is beneficial to industrialization manufacturing and use.

The utility model description of drawings is as follows:

Fig. 1 is the utility model structural representation

Below with embodiment the utility model is further elaborated.

Embodiment: with reference to figure 1, motor 1 is fixed on the bearing 2, the power shaft of motor connects with hollow rotating shaft 4 by shaft coupling 3, the two ends of hollow rotating shaft peripheral casing 5 connect with bearing 2 and supporting sleeve 7 respectively, the unenclosed construction form of bearing 2 for communicating with atmosphere, and hollow rotating shaft 4 surfaces and partly is provided with some air inlet ports 6, hollow rotating shaft 4 bottoms connect impeller shaft 8, set out pore 10 on the impeller shaft, also connect impeller 9 on the impeller shaft, impeller is that upper and lower bottom plate (11) and intermediary impeller blade constitute.Then whole proposal is implemented to finish.
