Abstract
The utility model relates to a microporous changeable aeration device, which is composed of an aeration head, an inserting plate and a supporting seat. The utility model is characterized in that the aeration head comprises a base and an air-spreading disc, the upper part of the base forms a V shape, the lower part of the base forms a circular arc shape, the air-spreading disc is arranged on the base, and the upper part of the air-spreading disc is covered with a special rubber film which is distributed with eyelets uniformly. The inserting plate forms a semicircle, and the inserting plate is buckled on the lower part of an air distribution tube. The supporting seat is an adjustable steel plate support arranged at the lower part of the inserting plate. The aeration device has novel structure, good performance, high oxygenation power efficiency, no blocking problem and long service life, and the utility model is suitable for biochemistry aeration engineering with water depth of 3-8 meters.
Description
The utility model belongs to Water and Waste Water Engineering, is used for the equipment that production waste and municipal effluent are handled.
For production waste and municipal sewage treatment, a lot of technologies are arranged, as: step aeration system, tapered aeration, extended aeration process, pure-oxygen aeration method, deep well aeration method and A/O method, A
z/ O method, SBR method etc. in these artificial-strengthening processes, mainly charge into oxygen by aerating system, for the microbiological deterioration organism in sewage.The aerator that is used for aerating system at present, mainly form by aeration head, bearing, pass through bearing, aeration head is installed on the gas distribution pipeline, and aeration head top is provided with air-spreading disk, places rubber diaphragm on the top of air-spreading disk, eyelet is set on rubber diaphragm, when blast aeration, air spreads out from eyelet, thereby reaches the efficient that oxygen shifts.Because General Purpose Rubber diaphragm-operated elasticity reaches the influence of the higher acid of not anti-concentration, alkali, benzene, phenol, wet goods medium, diaphragm is very easily damaged, the aeration head that has is provided with stationary installation at the diaphragm middle part, but also there is the diaphragm-operated problem of tearing, and bearing directly is fixed on the gas distribution pipeline, make aeration head installation, to adjust construction unfavorable, the power consumption that is in operation of these equipment is very big in addition, can account for about 70% of treatment plant's working cost usually.
The purpose of this utility model is a kind of novel micropore variable aeration device of design, and it is rational in infrastructure, superior performance, and the power efficiency of oxygen supply height, long service life, effect is good.
Micropore variable aeration device of the present utility model, by aeration head, plate, bearing is formed, it is characterized in that: aeration head is by the base of section for " V " font, circular air-spreading disk constitutes, the bottom of base is circular arc and is sitting on the gas-distribution pipe, and be provided with the angle ear of protrusion in both sides, the inlet mouth that communicates with gas distribution pipeline is set on base, inlet mouth is provided with the non-return valve unit that can open with air inlet, air-spreading disk is placed on the base, cover the rubber diaphragm of uniform eyelet on the top of air-spreading disk, air-spreading disk and rubber diaphragm are tightened on the screw socket on base limit by pressing solidly annulus; Plate is semicircle, is buckled in the bottom of gas-distribution pipe and the angle ear of base both sides and is seated; Bearing supports for the steel plate that the plate bottom is provided with, and the screw on it is a Long Circle, forms the liftable bearing.
The qi-emitting hole of described air-spreading disk is an elongated hole, in the periphery setting of dish.
Described rubber diaphragm is not provided with eyelet at air-spreading disk periphery qi-emitting hole place.
Micropore variable aeration device of the present utility model, its working process is: during blast aeration, air is entered between diaphragm and the air-spreading disk through air-spreading disk by the air inlet port of base, under the pressure effect of gas blower, diaphragm is heaved slightly, and eyelet opens, and air spreads out from eyelet, form trickle bubble, thereby reach very high oxygen transfer efficiency.When stopping air feed, the non-return valve unit on the inlet mouth is closed, and air pressure disappears, diaphragm self elasticity and suction function under make the eyelet closure because the effect of water pressure, on the tangible air-spreading disk of pressing diaphragm, mixed solution in the aeration tank can not blow back in the blast main, more eyelet can not stopped up.
Micropore variable aeration device of the present utility model, diaphragm adopts elasticity extremely strong, be difficult for aging, can acid-and base-resisting, the rubber making of making of oil and exotic materials stupid, phenol, it is thinner that diaphragm can be done, the aperture can increase or dwindle, thereby eyelet when opening the duct shorter, even contain a small amount of dust in the air, also can pass through eyelet, can not result in blockage, therefore before blast apparatus, can not establish dust removal installation, simplify air-blast system, save investment; The base bottom of aeration head is rounded, coincide with gas distribution pipeline, makes air supply outlet short to the path of air-spreading disk, and air feed is direct; The plate and the base that are provided with in the bottom of gas distribution pipeline are pegged graft, construction install convenience, and bearing is arranged to the liftable bearing, and it is easy that installation is regulated.
Micropore variable aeration device of the present utility model, its principal feature and technical feature are: under 5 meters depth of water situations, during 2 cubic metres of tolerance, coefficient of oxygen utilization is 28.8%; Dynamic efficiency 7.65; Resistance 180 millimeter water column in the water.This aerator novel structure, excellent property, there is not blockage problem in the power efficiency of oxygen supply height, long service life, effect is good.Be applicable to the biochemical aeration engineering of 3~8 meters of the depth of waters.
Below in conjunction with drawings and Examples micropore variable aeration device is described further.
Fig. 1 is a micropore variable aeration device topology view
Fig. 2 is the vertical view of Fig. 1
As can be seen, a kind of micropore variable aeration device, by aeration head, plate, bearing is formed, it is characterized in that: aeration head is by the base 1 of section for " V " font, circular air-spreading disk 2 constitutes, base is made by ABS plastic, the bottom is circular arc and is sitting on the gas-distribution pipe 3, and be provided with the angle ear 4 of protrusion in both sides, the inlet mouth 5 that communicates with gas distribution pipeline is set on base, inlet mouth is provided with the non-return valve unit 6 that can open with air inlet, air-spreading disk is placed on the base, qi-emitting hole in the periphery setting of coiling is an elongated hole 10, top at air-spreading disk covers the diaphragm of being made by specialty elastomer 11, and the uniform eyelet of quincunx spacing is set in the rubber diaphragm, and the rubber diaphragm is not provided with eyelet at air-spreading disk periphery qi-emitting hole place; Pressing solidly annulus 7 is tightened in air-spreading disk and rubber diaphragm on the screw socket on base limit; Plate 8 is semicircle, is buckled in the bottom of gas-distribution pipe and the angle ear of base both sides and is seated; Lifting support 9 supports for the steel plate that the plate bottom is provided with, and the screw on it is a Long Circle.
