The plastic sheet overlaid and mounted porous aeration equipment has the characteristics that the structure is compact and reasonable; the service life is long, and cleaning and exchange are not needed; service area is large, resistance is small, and operation is stable and reliable; adaptability is strong, the equipment is suitable for purification treatment of various sewages; and oxygen utilization rate is high, bubbles are uniform, and no dead angle is generated, thereby solving the problems generated by using the traditional aeration oxygenation equipment and having better aeration effect.
Description
Technical field
The present invention relates to a kind of aeration oxygen replenishing equipment of aeration tank, be used to be installed in aerated conduit,, belong to the environmental protection equipment technical field the sewage aseptic.
Background technology
Aerating apparatus is present as the existing long period of sewage disposal technology, and in contact oxidation method, arriving in the sewage treatment process such as activated sludge process is extensive use of, as corundum aerator, rubber aerator etc.Phenomenons such as but the disadvantage that these aeration oxygen replenishing equipment exist is exactly that drag losses is bigger, easily stops up, and is easily aging, and coefficient of oxygen utilization is not high, and bad adaptability easily produces the dead angle, and bubble is inhomogeneous, and maintenance is very inconvenient, influences the dissolved oxygen effect of aeration tank.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned the deficiencies in the prior art, a kind of plastic sheet stack fixed orifices aerator is provided, utilize its particular structure form, solved aeration oxygen replenishing equipment resistance loss big, easily stop up, easily aging, coefficient of oxygen utilization is not high, bad adaptability, easily produce problems such as dead angle, inconvenient maintenance.
The technical solution used in the present invention is as follows:
A kind of plastic sheet stack fixed orifices aerator, it is characterized in that it includes union lever, a plurality of aerator disks are installed on the described union lever, the diameter of each aerator disk increases successively, and it is tapered to be superimposed, the lower end of described union lever is equipped with fixed interface, and the lower end of fixed interface is equipped with intake interface.
In the described intake interface vacuum breaker is installed.
Described union lever, aerator disk, fixed interface, vacuum breaker, intake interface all adopt plastic material.
Described aerator disk can be random geometry, promptly can be trilateral, circle, square or the like any set figure, and aerator disk reduces successively or increases from the stack diameter.
Described each inner air chamber that forms hollow in aerator disk stack back, the contact cross section between each aerator disk is provided with some small grooveds air outlet, and diameter is in the scope of 0.1mm-1.5mm.
Described union lever lower end is threaded with fixed interface top, and the bottom of fixed interface also is threaded with intake interface top, and the intake interface lower thread is connected on the gas distribution pipeline.
Described union lever is provided with the flute profile air inlet port.
The invention has the beneficial effects as follows:
Utilize its particular structure form, solved aeration oxygen replenishing equipment resistance loss big, easily stop up, easily aging, coefficient of oxygen utilization is not high, bad adaptability, easily produce problems such as dead angle, inconvenient maintenance, can be widely used in the purifying treatment of all kinds of sewage.Compact construction, rationally; Long service life does not need cleaning to change; Service area is big, and resistance is little, stable and reliable operation; Adaptability is strong, is applicable to the purifying treatment of all kinds of sewage; The coefficient of oxygen utilization height, bubble is even, and no dead angle produces, and can substitute traditional oxygenating device fully, and have better aeration effect.
Description of drawings
Fig. 1 is a perspective view of the present invention.
Fig. 2 is a cross-sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described:
As shown in Figure 1, 2, the present invention is made up of union lever 1, aerator disk 2, fixed interface 3, vacuum breaker 4, intake interface 5 five parts.Union lever 1 is passed in each aerator disk 2 stack, and union lever 1 lower end is threaded with fixed interface 3, in order to fix each aerator disk 2.Each aerator disk 2 diameter increases successively, forms tapered structure, for example conical, square, trapezoidal and inverted conical, trapezoidal or the like, and conical optimum in these shapes, reason is that conical gas distribution is more even.Contact cross section between each aerator disk 2 is provided with some small grooveds air outlet 6, is used to give vent to anger.Small grooved air outlet 6 diameters are in 0.1mm-1.5mm.The reason that is limited to 0.1-1.5mm is: the bubble diameter the best that in this scope, is produced, and oxygen-transfer efficiency is the highest, is lower than can't to give vent to anger, and drag losses increases, and is higher than this scope and can causes bubble excessive, has lost the effect of micro-pore aeration.
Described fixed interface 3 bottoms are threaded with intake interface 5 tops, and vacuum breaker 4 places in the intake interface 5, when air feed, air backs down vacuum breaker 4, and gas enters, when stopping air feed, vacuum breaker 4 falls after rise, blocks the inlet mouth of intake interface 5 inside, prevents sewage backflow.Union lever 1 bottom is provided with the outside screw interface, fixed interface 3 tops are provided with internal thread interface, fixed interface 3 bottoms are provided with internal thread interface, intake interface 5 tops are provided with the outside screw interface, the bottom is provided with internal thread interface, described union lever 1 lower external thread interface is connected with described fixed interface 3 upper internal threaded interfaces, and fixed interface 3 lower internal thread interfaces are connected with intake interface 5 upper external thread interfaces, and intake interface 5 lower internal thread interfaces are connected with the gas distribution pipeline.Union lever 1 among the present invention, aerator disk 2, fixed interface 3, vacuum breaker 4, intake interface 5 all adopt plastic material.
Working process of the present invention is as follows:
Pressurized air enter hollow intake interface 5, back down vacuum breaker 4, enter fixed interface 3 then, through 1 grooved air inlet port 7 on the union lever, enter the inner hollow air chamber 8 that each aerator disk 2 stack forms at last, air in air chamber through the extruding, by the small grooved air outlet 6 on each aerator disk 2 contact cross section, form micro-bubble, oxygenation in the water body of aeration tank.
The undeclared part of other that the present invention relates to is same as the prior art.
