Abstract
An integrated microporous aerator with a corundum tube comprises the corundum tube (2), an internal thread vent connection (1) and a non-return device (4), wherein a sealing piece (3) is arranged at the tail end of the corundum tube (2); the internal thread vent connection (1) is mounted at the head end of the corundum tube (2); the corundum tube (2), the sealing piece (3) and the internal thread vent connection (1) are formed through integrated sintering; a space defined by the corundum tube (2), the sealing piece (3) and the internal thread vent connection (1) serves as an aerator cavity; and the non-return device (4) is embedded on the inner wall of the internal thread vent connection (1). The invention has the advantages of one-time sintering forming, good leak tightness, high stability, reduction of raw material waste and cost economization. Through the arrangement of the non-return device, the defect that the corundum aerator is easy to back flow and block, resulting in influencing the service life is solved. Therefore, the integrated microporous aerator is wide in the application range.
Description
Technical field
The invention belongs to the environmental protection field, relate to integral type alundum tube micro-hole aerator.
Background technology
Aerator is the key equipment in sewage work's biological treatment.The main purpose of aeration be the new one-tenth metabolism for mikrobe needed oxygen is provided and play stirring, mixing effect can fully contact mikrobe with dissolved oxygen and the organism that in water body, suspends, and promotes organic microbiological deterioration.The gas or the volatile matter of dissolved state in the water body are dispelled in the atmosphere.
Corundum adopts the emergy (AL that hardness is big, chemical property is very stable, corrosion resistance nature is strong
2O
3), ceramic binder forms through high temperature sintering; Thereby have HS, corrosion resistance characteristic, and being fit to the corrosive atmosphere of sewage, microbubble diffusion disc surface is difficult for adhering to biological sludge; Strong to resistivities such as oil, acid, alkali, esters simultaneously, product-free problem of aging so long service life.
Present corundum aerator exists interconnecting piece many, and interconnecting piece material difference causes the coefficient of expansion different with digestion time, and life-time service is deposited big big problem to the stopping property of aerator.In addition, because aeration tube assembly when producing is more, comprise that two outer silk threaded connectors, damping connect end; Rubber tail end end socket, stainless steel anchor ear each item assembly all need corresponding mould, take manual work during assembling, and installation process is difficulty particularly; Structure is also complicated, so cost is high.
Existing aerator adopts the butterfly reverse checkvalve usually; Because Sewage Plant adopts blast aeration, have more impurity in the air He in the pipeline during its actual motion, aerator need bear 60 ~ 90 ℃ high-temperature gas in addition; Adopt the butterfly reverse checkvalve in this case; To its result of use and life-span is great test, and rubber in use all can appear in the rubber aerator to be torn, and such reverse checkvalve in use exists the problem of tearing bigger.Aerator is the equipment of long-time running, and reverse checkvalve air after receiving the pressure of air could get into the aeration tube inner chamber, and this reverse checkvalve is in during chronic fatigue uses, and it in use belongs to high-frequency unit, fractures easily.

Summary of the invention
The objective of the invention is to overcome the weak point of prior art, a kind of integral type alundum tube micro-hole aerator is provided.This aerator adopts disposable sinter molding, and is simple in structure, and good airproof performance is multiple functional, and is applied widely, easy for installation, and efficient energy-saving is with low cost.
A kind of integral type alundum tube micro-hole aerator; It comprises alundum tube, IT ventilating joint and check device; The tail end of described alundum tube is provided with sealing member, and the IT ventilating joint is installed in the head end of alundum tube, alundum tube, sealing member and the moulding of IT ventilating joint integral sintering; The space that alundum tube, sealing member and IT ventilating joint surround forms the aerator cavity, and described check device is embedded on the inwall of IT ventilating joint.
Alundum tube of the present invention is the micropore air diffuser tube of a right cylinder formula hollow.
Check device of the present invention comprises duck-beak type vacuum breaker, outside screw check device strut member and anticreep snap ring; Described anticreep snap ring is installed in the duckbilled end of duck-beak type vacuum breaker; Outside screw check device strut member is sleeved on the outer wall of duck-beak type vacuum breaker, and outside screw check device strut member is threaded with the IT ventilating joint.
Anticreep snap ring of the present invention is a rubber parts.
The outer wall of sealing member of the present invention be provided with one be used to support the alundum tube tail end the hole, this hole and aerator cavity separate.
Advantage of the present invention and positively effect are:
1, this aerator adopts same material to process base; The micropore air diffuser tube, IT ventilating joint, the tail end sealing spare that comprise hollow; Adopt high temperature clay bonding, once sintered shaping, the xln of same material has solved the problem of stopping property, poor stability; Reduce raw-material waste, saved cost.
2, this aerator is provided with check device, has solved the corundum aerator, is prone to pour in down a chimney, and is prone to stop up, and influences weak points such as work-ing life, and this aerator is applied widely.
3, to adopt selected silicon carbide be that main raw material and multiple subsidiary material and sticker are made into to this aerator.Improved the porosity of aerator, atmospheric drag loss when having reduced aeration, the bubble of generation mikrobe preferably absorbs, and embodies the advantage of this aerator energy saving, consumption reduction and high efficiency.
4, this aerator adopts mechanical stamping to be shaped, and product strength is big, and yield rate is high, and transportation installation process breakage rate is low.
