Abstract

The utility model is an aeration device used for an environment-friendly aerobic sewage biological and chemical treatment aeration tank, which is characterized in that: the aeration device comprising a multi-functional dynamic rotating and mixing core, a divided flow ring, an intercalated tooth cover and an inverted tooth divergent cover fully utilizes the upward floating power of gas in the water body to obtain fine bubbles by the power divergent function that produces swirling flow and mixing and prevents impacts, the power divergent method of the aeration device radically solves problems of strong resistance, easy blockage and low durability due to the adoption of the micro-pore method for acquiring fine bubbles, and the utility model has techniques of systematic stopping and automatic regulating of the exhaust pore.

Description

Mixed aerator is revolved in the power diffusion

Affiliated technical field

The utility model is a kind of aerator that is used for the aerobic sewage biochemical treatment of environment protection aeration tank.

Background technology

In aerobic sewage biochemical processing process, be to utilize the breeding culturing micro-organisms that the organic pollutant in the water body is decomposed, reach the purification of water quality purpose.The biochemical activity of microorganism must have oxygen source, and the function of aerator is exactly with the air of gas blower through pipe-line transportation, and diffusion is to provide microorganism needed oxygen source in water body.The gas-to-liquid contact interface that the bubble that is produced through the aerator diffusion forms when contacting with water body is the place that the oxygen transfer function takes place.The bubble that the diffusion of the tolerance of unit volume produces the more, the gas-to-liquid contact interface of formation is just bigger, then the oxygen transfer functioning efficiency is higher.What of the bubbles volume that is produced through aerator diffusion directly have influence on the oxygen transfer efficiency.

Air can produce rill when micro-pore is discharged in water body, based on such hole diffusion property, the hole diffusion process is that the main technique methods that rill adopts is obtained in present aerator diffusion." micro-pore " is the technological core of hole diffusion process, because the natural characteristics of " micro-pore " has determined the hole diffusion process to have following defective: (1) resistance of exhaust loss is big; (2) hole easily stops up; (3) source of the gas that enters aerating system there is strict dust removal and filtration requirement; (4) aerator wearing quality and reliability are not high.

Summary of the invention

The utility model purpose is exactly the huge difference that makes full use of gas and water body proportion existence between the two, adopt the power diffusion process solve the insoluble resistance of hole diffusion process big, easily stop up, problem such as engineering reliability is low, improve the wearing quality of aerator, ensure sewage treatment process operation steady in a long-term.

Solution of the present utility model is: every cover aerator has only the exhaust macropore of one＞∮ 6, and air-flow is discharged the bubble that produces and spread tooth on the tooth cover → pawl diffusion shell 9 circle cone triangle diffusion pawls through the multi-functional mixed core → splitting ring diffusion internal tooth → splitting ring grid cylinder → interlayer diffusion tooth cover lower tooth → interlayer that dynamically revolves; Bubble with sizable come-up power through the aerator said process after, at eddy flow, stop, obtained sufficient fragmentation under the effect such as collision, thus the macropore exhaust rill operating performance of realization aerator; Be completely free of the notion of " micro-pore can to produce rill ", adopt the macropore exhaust mode to form rill, the power diffusion is revolved mix the advantage that aerator has little, the difficult obstruction of resistance of exhaust loss, efficient height, maintenance free free of replacement through the power diffusion; But also have system's non-return, the self-adjusting technical characterstic of exhaust apertures.

Embodiment

In Fig. 1, power diffusion revolves that to mix aerator be to adopt on the bell and spigot joint that (2) are fixed on aerator on the gas distribution pipeline (4) in the obvolvent mode by holding bolt (3) under (1) and bell and spigot joint, go up the directly air vent of brill＞∮ 6 (5) according to load and equilibrium relationship at gas distribution pipeline (4), every cover aerator bores a hole.On the bell and spigot joint under (1) and the bell and spigot joint (2) be that aerator is fixed on the gas distribution pipeline (4) on the one hand, on the other hand by the positioned centrally bolt (20) on the cross crosspiece (7) with other parts of aerator: the multi-functional mixed core (10), splitting ring (12), interlayer diffusion tooth cover (15), pawl diffusion shell (18) of dynamically revolving waits to make up and assembles.Be in operation, some gas-distribution pipes bottom might form and be difficult for the ponding of discharging, and influences the operation of aerator for preventing this class dead angle ponding, is provided with a water conservancy diversion intubate (6) at the bottom of being pressed in the tubular stinger that (2) are located under (1) and bell and spigot joint on the bell and spigot joint.

Air by gas distribution pipeline (4) boring (5) input at first spreads discharge through bell and spigot joint qi-emitting hole (8) shown in Figure 2 multi-functional dynamically revolving under mixed core (10) effect.Multi-functional dynamically revolving inlayed counterweight tinsel (21) in the mixed core (10), perimeter ramps be arranged in parallel one the circle blade (11), during the aerator operation, air-flow can make the multi-functional mixed core (10) that dynamically revolves locate to do upper and lower change crack motion at bell and spigot joint platform (9) shown in Figure 2 and revolve with rotation and mix motion, when aerator was out of service, the multi-functional mixed core (10) that dynamically revolves had the non-return effect.Splitting ring diffusion internal tooth (13) among Fig. 3, the interlayer diffusion tooth cover lower tooth (16) among Fig. 4 and last tooth (17), pawl diffusion shell (18) all are that the bubble that has the come-up motion plays the broken power diffusion of multiple collision.
