Background technology
Aerator is the necessary equipment of plumbing aeration aerating, can be divided into surface aerator and underwater aerator by using method, and underwater aerator mainly contains micro-hole aerator and jet aerator.Wherein disc type diaphragm aerator belongs to the one in micro-hole aerator, disc type diaphragm formula aerator is the latest model aerating apparatus of the development eighties, this device aeration bubbles diameter is little, and liquid-gas interface diameter is little, and gas-oil interfaces is large, bubble diffusion evenly, can not produce eyelet blocking, erosion resistance is strong, fixes spiral aerator than conventional products, air diffusion aerator and perforated pipe aerating regulation device energy consumption reduce by 40%, or increase sewage load 40%.Be specially adapted to the newly-built enlarging of municipal effluent and integrated mill and the transformation of old aeration tank, and aeration tank can intermittent operation, but occurred some insoluble deficiencies by operation for many years.As: diaphragm comes off, diaphragm is torn, diaphragm is not opened, mud enters the problems such as segmental bronchus.
In addition, traditional plate-type aerator, the place that diaphragm is sent into by supporting plate corresponding to air has aperture, the phenomenon flow backwards easily is there is when aeration, equipment is suffered damage, next is the anti-floating problem of aerator, base in aerator is then generally be fixed on pipe by the mode of gluing or molten weldering, gluing or molten weldering is required great effort very much, because the water quality of sewage work is complicated, corrodibility is larger, easily gluing or molten wlding material to be eroded thus the connection causing aerator and air to be responsible for is slided, also there is the problem of not easily aiming at air feed port simultaneously, the solid power deficiency of aerator is caused to cause floating accident, above defect can directly cause aerator to consume a large amount of power, the efficiency of aeration is low, local oxygen supply is not enough, treatment efficiency is low, finally cause sewage work's running cost high and can not normally run, inconvenience is brought to the life of people, a kind of disc type diaphragm aerator that can overcome above defect becomes those skilled in the art's technical problem urgently to be resolved hurrily thus.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides one not easily to block, and effective anti-water-stop body flows backwards, and effective aeration area is large, and intensity is high, long service life, the disc type diaphragm aerator of good seal performance.
In order to solve above technical problem, the utility model provides a kind of disc type diaphragm aerator, comprise spiral cover, diaphragm, base, diaphragm arrangement, between described spiral cover and base, is also provided with water conservancy diversion support plate between diaphragm and base, arranges the vacuum breaker that ports valve is unified between water conservancy diversion support plate and base, base is provided with filter bowl, filter bowl can be round shape or taper shape, and the below of base is also provided with the wedge of falling the shape of a saddle, wherein:
Diaphragm is provided with multiple perforate, and perforate is bar shaped micropore, and the edge of water conservancy diversion support plate is evenly provided with through hole;
Base is made up of the round shape chassis of upper end open and shape of a saddle support, chassis and shape of a saddle support all have hole, chassis is fixedly attached on shape of a saddle support by hollow bolt, and the outside screw be provided with in chassis outside internal thread and spiral cover is suitable, is provided with outside screw outside chassis;
The outside screw that the inwall at filter bowl lower ending opening place is provided with outside internal thread and chassis is suitable, and filter bowl is threaded on chassis.
The technical scheme that the utility model limits further is:
Aforementioned disc type diaphragm aeration equipment, shape of a saddle support matches with the wedge of falling the shape of a saddle and is connected on breather line, is provided with O-ring seals between breather line and shape of a saddle support.
Aforementioned disc type diaphragm aeration equipment, the bar shaped micropore on diaphragm is concentric(al) circles distribution and is reduced gradually to center by diaphragm periphery.
Aforementioned disc type diaphragm aeration equipment, the diameter of filter bowl is greater than the diameter of base top bottom-disc, and during adjacent two aerators arrangement, have certain gap between two filter bowls, the diameter of selected filter bowl does not hinder the normal use of aerator.
Aforementioned disc type diaphragm aeration equipment, diaphragm, vacuum breaker, O-ring seals all adopt terpolymer EP rubber material to make.
The beneficial effects of the utility model are:
The utility model diaphragm is opened bar shaped micropore, bar shaped micropore is concentric(al) circles distribution and is reduced gradually to center by diaphragm periphery, under the prerequisite meeting aeration rate, increases effective aeration area.
Adopt water conservancy diversion support plate to support diaphragm and the edge of water conservancy diversion support plate is evenly provided with through hole in the utility model, the gas in breather line is made to pass to diaphragm uniformly from the through hole of edge during aeration after water conservancy diversion support plate buffering, overflowed by the micropore on diaphragm and ensure to form small bubbles at 1-3mm, size is even.
In the utility model, chassis adopts hollow bolt to be affixed on shape of a saddle support, and hollow bolt plays fixing effect on the one hand, is also the passage to aerator air feed on the other hand, saves the cost of equipment.
The utility model adopts the vacuum breaker of ports valve unification, and the hole in vacuum breaker can be lost by build-up of pressure, but makes the air-flow in the aerator in whole system reach balance.Vacuum breaker can effectively stop aqueous reflux to enter breather line, reduces aeration resistance, and then reduces the loss of power, and the effect that improve aeration improves the work-ing life of aerator simultaneously.
Base of the present utility model has been threaded filter bowl, assembly and disassembly is convenient, the micropore on the suspended substance that particle is large or sack blocking diaphragm can be stoped during aeration, after stopping aeration, avoid sludge settling in water to accumulate in diaphragm increases again resistance during aeration, extend the work-ing life of aerator.
The utility model aerator does not stick with glue or molten weldering is fixed on official road, and being cooperatively interacted by the shape of a saddle support on base and the wedge of falling the shape of a saddle is tightened together firmly by mechanical force.Avoid because water quality is complicated, corrodibility is comparatively large, is easily eroded by gluing or molten wlding material thus causes aerator to be connected with breather line and slide, and the solid power deficiency of aerator causes floating accident.
The utility model is provided with O-ring seals between breather line and shape of a saddle support, aerator and breather line are combined closely, the phenomenon of gas leakage water inlet can not be produced, also reduce the friction between shape of a saddle support and breather line simultaneously, extend the work-ing life of aerator.
In the utility model diaphragm material adopt terpolymer EP rubber, to municipal wastewater and most industry sewage chemical corrosion stability high, thermotolerance can reach 100 DEG C by force, reduces the speed that diaphragm is aging simultaneously; Vacuum breaker also adopts terpolymer EP rubber to most of inorganic chemistry thing, mineral acid, alkali and low-molecular-weight alcohol, ketone tool and phenols have corrosion stability: O-ring seals adopts terpolymer EP rubber equally, wear resistance, erosion resistance is stronger, extends the work-ing life of whole aerator.
The utility model structure is simple, and assembly and disassembly is convenient, not easily blocks, and effective anti-water-stop body flows backwards, and effective aeration area is large, and intensity is high, long service life, good seal performance.
