The invention discloses plastic sheet overlaid and mounted porous aeration equipment which is characterized by comprising a connection rod (1), wherein the connection rod (1) is provided with multiple aeration sheets (2); the diameters of the aeration sheets (2) are successively increased, and the aeration sheets (2) are overlaid to form a cone shape; a fixed interface (3) is installed on the lower end of the connection rod (1); and a gas inlet interface (5) is installed on the lower end of the fixed interface (3). 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 widely used, like 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, is prone to stop up, and is prone to wear out, and coefficient of oxygen utilization is not high, and bad adaptability is prone to produce the dead angle, and bubble is inhomogeneous, and maintenance is very inconvenient, influences the dissolved oxygen effect of aeration tank.
Summary of the invention
The object of the invention is exactly the deficiency to above-mentioned 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, be prone to stop up, be prone to aging, coefficient of oxygen utilization is not high, bad adaptability, the problems such as dead angle, inconvenient maintenance that are prone to produce.
The technical scheme that the present invention adopts is following:
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 said union lever, and the diameter of each aerator disk increases successively, and it is tapered to be superimposed; The lower end of said union lever is equipped with fixed interface, and the lower end of fixed interface is equipped with intake interface.
In the said intake interface vacuum breaker is installed.
Said union lever, aerator disk, fixed interface, vacuum breaker, intake interface all adopt plastic material.
Said 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.
Said each inner air chamber that forms hollow in aerator disk stack back, the contact xsect between each aerator disk is provided with some small grooveds air outlet, and diameter is in the scope of 0.1mm-1.5mm.
Said 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.
Said union lever is provided with the flute profile production well.
The invention has the beneficial effects as follows:
Utilize its particular structure form, solved aeration oxygen replenishing equipment resistance loss big, be prone to stop up, be prone to aging, coefficient of oxygen utilization is not high, bad adaptability, be prone to 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 need not cleared up replacing; Service area is big, and resistance is little, stable and reliable operation; Flexibility is strong, is applicable to the purifying treatment of all kinds of sewage; Coefficient of oxygen utilization is high, and 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 done explanation further:
Like Fig. 1, shown in 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 fixing 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 xsect 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 that in this scope, is produced is best, and oxygen-transfer efficiency is the highest, is lower than and can can't gives 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.
Said 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 gets into, 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, and fixed interface 3 bottoms are provided with internal thread interface, and intake interface 5 tops are provided with the outside screw interface; The bottom is provided with internal thread interface; Said union lever 1 lower external thread interface is connected with said 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 following:
Pressurized air get into hollow intake interface 5, back down vacuum breaker 4; Get into fixed interface 3 then, through 1 grooved air inlet port 7 on the union lever; Get into the inner hollow air chamber 8 that each aeration 2 stack forms at last, air is the warp extruding in air chamber, through the small grooved air outlet 6 on each aerator disk 2 contact xsect; Form micro-bubble, oxygenation in the water body of aeration tank.
The undeclared part of other that the present invention relates to is identical with prior art.
