Abstract
The utility model relates to an electric large-sized aerator which mainly comprises a motor and an aeration head which is driven by a rotatable hollow ventilating rotating shaft. The aeration head is provided with a blade with fine pit veins, and the blade is folded to be a row of micro holes; blades can form a firm impeller with a plurality of ventilating holes. At the time of rotating, the impeller is designed to be a profile shape which reaches the stirring action. The utility model has the advantages that the air is sent into the aerator with an air blower and is discharged through the small holes of the aerator to form small air bubbles; because of rotation, the stir is formed to make the air bubbles diffuse the water, and the contact time and the solubility of the oxygen in water are increased. The aerator has the advantages of light load and electricity saving and has the double functions of stirring and aeration.
Description
The utility model relates to a kind of sewage disposal ground aerating apparatus that is used for, and especially relates to the aerating apparatus with driven by motor, belongs to the C02F3/16 class.
At present, two kinds of different aeration modes are often used in sewage disposal: a kind of is the surface aeration mode, adopts the aerator and the impeller of driven by motor, plays spray and aeration.Its shortcoming is to absorb oxygen at water surface, and bigger blade is commonly used, and iron and steel is made easily gets rusty, and pond or cylinder also can not be too dark; Another kind of mode is to adopt to place at the bottom of cylinder bottom or the pond aeration head in deep under water, with the gas blower aeration, is usually used in large-scale sewage disposal.But the drainage flow in the cylinder is relatively poor, stink is bigger.
The purpose of this utility model is at above-mentioned shortcoming, provides a kind of and can absorb oxygen non-corrosive again in a large number; Can strengthen the aeration effect has agitating function again, thereby acceleration is mobile, reaches the electronic folded formula aerating apparatus of quick elimination stink.
The purpose of this utility model is achieved in that a kind of electronic aerator, comprise that motor and hollow rotationally ventilation rotating shaft drive the ground aeration head, this aeration head is the blade with fine hole line, stack the impeller that then becomes several rows of aperture, multi-disc to stack to constitute firmly many ventilating pits and play stirring action more than two.
Also projection or pit can be made on the blade, air passageways can be formed through stacking more than two.
Rotating shaft one end is equipped with clutch coupling, and is motionless in this clutch coupling forward rotating shaft, can be used as air and is blown into the duct, driven the lower portion rotation of rotating shaft by clutch coupling.
Described aeration head synthesizes one group by some vane group, and by forming more than one group.
Because adopt such scheme, the utility model can be manufactured blade with film, so with low cost, maintenance simply; Because adopt the texture of making on the film, two stack, and form a lot of fine apertures, air is discharged the formation tiny bubble thus, to increase the solubleness of air in water, can make water absorb a large amount of oxygen and solve the problem of getting rusty again; Play the gabarit of stirring action different shape when stacking the impeller rotation that is combined into, can improve the mixing effect and the aeration effect of sewage in cylinder or the pond, thereby quicken flowability and take a breath and eliminate the sewage stink by blade.
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is the dimpled grain blade plane synoptic diagram of electronic folded formula aerator.
Fig. 2 is one group of burr blade plane of electronic folded formula aerator synoptic diagram.
Fig. 3 is one group of burr blade schematic side view.
Fig. 4 is a hanging aerator structural principle synoptic diagram.
Fig. 5 is a horizontal aerator structural principle synoptic diagram.
Fig. 6 is a vertical type aerator structural principle synoptic diagram.
To shown in Figure 6, motor 9 drives hollow rotating shaft 8 by belt or chain 11 and rotates, and rotates with middling speed in water thereby drive aeration head 10 as Fig. 4; Air is blown into via blower fan, pore 2 on hollow rotating shaft 8 arrives duct 1, and after tiny dimpled grain hole 4 discharges on the blade 3 as shown in Figure 1, form tiny steam bubble 7, more the stirring because of blade is flowed water fast, small bubbles 7 are floated in water, increase the oxygen residence time and solute effect in water.
Tiny line hole on the blade 3 can be made into central small dimpled grain hole to the edge and stacks more than 4, two as shown in Figure 1, can form by the aperture 5 of center to the edge.
As Fig. 2, shown in Figure 3, blade 3 also can be made into burr 13.Cooperate the requirement of sewage disposal, this aerator also can be designed to following different modes:
(1) straight hanging and angle mount formula:
Be illustrated in figure 4 as straight hanging, the angle mount formula is similar with it to be an oblique angle.Above-mentioned two kinds of aerators are all directly packed in the cylinder.Air 6 is gone into by top blast on the hollow rotating shaft 8, and the aperture 5 on blade 3 blows out.Water level is fit to adopt the aerator of this type in the ordinary course of things.
(2) horizontal:
Be illustrated in figure 5 as the water-bed aerator of horizontal positioned down.Can adorn a plurality of aeration heads 10 under the bottom on hollow rotating shaft 8, air 6 is blown at rotating shaft one end, and motor 9 drives rotating shaft 8 with belt or chain 11 on the ground; The horizontal aeration device is fit to microscler cylinder or pond.
(3) uprightly fixed:
Be illustrated in figure 6 as upright fixed aerator.It is fixed on cylinder bottom or the supporting rack, and aerator can be made up of the aeration head 10 that is contained in more than on the hollow rotating shaft 8.Air 6 is blown into the back by rotating shaft 8 one ends and is discharged by the aperture 5 of aeration head 10.The rotating shaft of upright fixed aerator is longer, is suitable for darker cylinder and liquid depth the higher person, as thickened sludge pond etc.
Claims (4)
1, a kind of electronic aerator, comprise that motor (9) and hollow rotationally ventilation rotating shaft (8) drive aeration head (10), it is characterized in that: aeration head (10) has the blade (3) of fine hole line (4), stack into several rows of aperture (5) more than two, multi-disc stacks the impeller that can constitute firmly many ventilating pits and play stirring action.
2, according to the described electronic aerator of claim 1, it is characterized in that: projection (13) or pit are arranged on the described blade (3), form air passageways (14) through stacking more than two.
3, according to the described electronic aerator of claim 1, it is characterized in that: described rotating shaft (8) one end is equipped with clutch coupling (12), motionless in this clutch coupling (12) forward rotating shaft (8), can be used as air and be blown into the duct, clutch coupling (12) drives rotating shaft (8) bottom.
