Description
Technical field
The utility model relates to the aerator using in environment-protective water treatment process, particularly a kind of surface aeration machine screw impeller.
Background technology
In sewage treatment process, commonly use aeration system, aeration form is varied, as air supporting, aeration head, blower fan, surface aeration machine etc.Surface aeration machine has simple in structure, and the feature that treatment capacity is large, is widely used, but present surface aerator blade is all straight plate shape, with main impeller direct-connected connecing radially all; When surface aeration machine rotates to churn the surface, fluctuate up and down excessively and unbalanced, water flow is irregular, and air is not smooth, and Air Bubble Size is uneven.
At present, the brushing piece upstream face that aeration machine impeller in prior art adopts with turn brush main-shaft axis in same plane, brushing piece in working order under, bear normal direction shearing force simultaneously, affect blade work-ing life; Meanwhile, the brushing piece of employing is to use steel plate punched brake forming, and the local stress that produces of brushing piece easily ruptures; Impeller of rotation brush aeration machine prior art is connected to one group with bolt, while relying on bolt to connect, the pretension distortion of brushing piece root compound rubber pad is clamped and is turned brush main shaft, forms integral wheel structure.
Publication number is that CN1792877A discloses a kind of aeration machine impeller, comprise by half-axile sleeve ring element and form the complete collar forming, described brushing piece is weldingly fixed on the outside surface of the collar, and the initial and tail sections of half-axile sleeve ring element is provided with the web plate connecting for same half-axile sleeve ring element.The upstream face of the brushing piece of this impeller with turn brush main-shaft axis form axial angle α; Described impeller is formed and is formed by two half impeller units that independently brushing piece of semicircular half-axile sleeve ring element and upper setting thereof forms, and described web plate is bolted; Between described brushing piece back side and half-axile sleeve ring element, be provided with reinforcement gusset; The plate face of one end web plate of described half-axile sleeve ring element fits into one with the upstream face of a contiguous brushing piece, and the spacing of the plate face of the web plate of the other end and a contiguous brushing piece is the spacing of adjacent two brushing pieces.
This aeration machine impeller is formed and is formed by half-axile sleeve ring element, and when half-axile sleeve ring element damages, the brushing piece being positioned on this half-axile sleeve ring element can not be worked, and causes the whole damage of aeration machine impeller, poor practicability.
Publication number is the shear blade that the Chinese patent of CN2157188Y discloses a kind of horizontal axis rotating brush aerator, and its blade both sides are spination, and on every group of impeller, the sawtooth of former and later two blades intersects mutually.Because blade both sides are zig-zag, so water is played to the effect of shearing, water flow cutting becomes little water droplet, and also can cut air becomes small bubbles simultaneously.
Simultaneously, disclosed technical scheme in Chinese patent CN2216524Y, CN2175226Y, below be all to rely on the distortion of brushing piece root to clamp the organization plan that turns brush main shaft, the situation that easily occurs brushing piece fracture of root, as long as there is the bolt connecting portion of two brushing pieces of arbitrary neighborhood to rupture, will cause that the integral wheel that all brushing pieces form all falls into sewage; Meanwhile, so many brushing piece connects to transportation, installs and maintenance brings great difficulty and brushing piece complex forming technology, manufacturing cost high with bolt.
Utility model content
In order to overcome defect of the prior art, the utility model proposes a kind of existing axial impellent also has outside tangent line impellent, has simple in structurely, and dynamic efficiency is high, processes the large surface aeration machine screw impeller of water meter area.
The utility model is achieved through the following technical solutions:
A kind of surface aeration machine screw impeller, comprise impeller bodies, described impeller bodies central authorities arrange transmission shaft, the uniform impeller gap of described impeller bodies surrounding, described impeller gap left side is provided with perpendicular blade, described perpendicular blade right side is provided with oblique blade, and integral body spiral centered by transmission shaft of described perpendicular blade and oblique blade composition is installed in impeller bodies.
Further, described oblique blade and perpendicular blade are all circular-arc.
Further, between described perpendicular blade and transmission shaft, be provided with stiffening plate.Described stiffening plate has increased the stability of described perpendicular blade and transmission shaft.
Further, described perpendicular blade, oblique blade are all connected with described impeller bodies by welding process.
Compared with prior art, a kind of surface aeration machine described in the utility model is by the superior effect of screw impeller: described screw impeller is simple in structure, by described perpendicular blade and oblique blade, stir water body, make water body in the process of shedding, entrain into air, and water body is fully contacted with air, steadily, dynamic efficiency is high, process water meter area large, thereby strengthen oxygenation capacity, improve aeration efficiency.

Embodiment
Below in conjunction with Figure of description, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in accompanying drawing 1-6, a kind of surface aeration machine screw impeller, comprise impeller bodies 1, described impeller bodies 1 central authorities arrange transmission shaft 4, the uniform impeller gap 6 of described impeller bodies 1 surrounding, described impeller gap 6 left sides are provided with perpendicular blade 3, and described perpendicular blade 3 right sides are provided with oblique blade 2, and integral body spiral centered by transmission shaft 4 of described perpendicular blade 3 and oblique blade 2 compositions is installed in impeller bodies 1.As shown in Figure 3, described impeller bodies 1 is provided with seven impeller gap 6.
Described oblique blade 2 and perpendicular blade 3 are all circular-arc.
Between described perpendicular blade 3 and transmission shaft 4, be provided with stiffening plate 5.Described stiffening plate 5 has increased the stability of described perpendicular blade 3 and transmission shaft 4.
Described perpendicular blade 3, oblique blade 2 are all connected with described impeller bodies 1 by welding process.
When mounted, at the perpendicular blade 3 of the left side of described impeller gap 6 welding, between described perpendicular blade 3 and impeller gap 6, weld described oblique blade 2, form minute water plate on sealing slope curve.
When described screw impeller is rotated counterclockwise as shown in Figure 1, under the brute force of the oblique blade 2 of helical arrangement and perpendicular blade 3 promotes, the spiral motion that sewage is violent, sewage is tentiform and throws away to surrounding from impeller edge, forms water curtain and the spray, wraps up in into large quantity of air.
Violent spiral motion due to sewage, because circular arc vane spiral form arranges, in the time of feedwater rotation direction impellent also to surrounding diffusive force, cause the upper and lower smooth and easy circulation of water body, constantly update liquid level, sewage big area contacts with air, vane rotary drives water body flow, forms negative pressuren zone, air amount, airborne oxygen dissolves in rapidly in sewage, complete the oxygenation to sewage, simultaneously powerful power wheel drive, stirs a large amount of water body flows, thereby realize, mix and pushing effect, in oxidation ditch, make water body produce spiral promotion effect.
The utility model is not limited to above-mentioned embodiment, and in the situation that not deviating from flesh and blood of the present utility model, any distortion it may occur to persons skilled in the art that, improvement, replacement all fall into scope of the present utility model.
