Abstract
The utility model discloses a micropore-variable blockage-preventing aerating hose. The micropore-variable blockage-preventing aerating hose comprises an inner layer and an outer layer, wherein the inner layer is formed by weaving polyester yarns into a netlike sleeve; the outer layer is formed by coating polyvinyl chloride and an anti-aging agent; a plurality of variable micropores are formed on the circumferential surface of the hose; during aeration, the hose is expanded and the variable micropores are open; without aeration, the hose is flattened and the variable micropores are closed. The micropore-variable blockage-preventing aerating hose fully embodies three modern wastewater treatment efficacies of aeration, stirring and scouring, and meets general requirements of wastewater treatment on practicality, simplicity, convenience and cheapness.
Description
Technical field
The utility model relates to a kind of water treatment device, is specifically related to the anti-blocking aeration flexible pipe of a kind of variable micro-hole.
Background technology
Aerating apparatus is the very crucial equipment of biochemical treatment sewage, and it is bright that aerating apparatus whether reasonable not only affects the final effect of sewage disposal, and affects the operation life cycle of whole waste disposal plant, thereby affects the cost of sewage disposal.
Early stage aerating apparatus is a kind of perforated pipe of rigidity, its shortcoming is that oxygenation capacity is lower, inwall due to perforated pipe pipe after perforation processing produces burr unavoidably in addition, the burr place very easily makes microbial reproduction so that plug-hole,-the dawn stops aeration, pore is also very easily by sludge blockage. and someone has released not susceptible to plugging aeration spray head thereafter, but its oxygenation capacity is lower than perforated pipe.In order to improve oxygenation capacity, someone has released middle micropore, micro-hole aerator again, it is to allow air diffuse into through micropore ceramics the bubble that diameter is very little, its advantage is that liquid-gas interface is very large, and oxygenation capacity is higher, but shortcoming is the aerator complex structure, the parts rapid wear, and need inflate with air compressor machine, air must could be used after purifying, and whole facility investment is higher.The micropore ceramic aeration head very easily blocks in addition, must regularly by the method for roasting or pickling, carry out manipulation of regeneration.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of anti-blocking aeration flexible pipe of variable micro-hole that has oxygenation, stirs, washes away three large functions.
The technical scheme adopted is:
The anti-blocking aeration flexible pipe of a kind of variable micro-hole, comprise internal layer and skin, and described internal layer is woven into by polyester yarn that net forms, and described skin is that polyvinyl chloride adds anti-aging auxiliary agent plastic-coated and forms; Surface, described flexible pipe week footpath is provided with a plurality of variable micro-holes, flexible pipe bulging when aeration, and the open-shaped state of described variable micro-hole, when aeration not, flexible pipe is crushed, and described variable micro-hole is closed state.
Preferably,
Described variable micro-hole is slit-shaped, and during aeration, the slit length of variable micro-hole is not 2mm.
The slit length of described variable micro-hole and the axially parallel of described flexible pipe.
The quantity of described variable micro-hole is 3600/m.
During described flexible pipe aeration, inner diameter is 62.5mm, and inner diameter is not 58.5mm during aeration, and outer diameter is 62.5mm.
Advantage of the present utility model has:
1, there is variable micro-hole on surface, this flexible pipe week footpath, and bulging during aeration is not crushed by acting by external hydrostatic pressure during aeration, and variable micro-hole is closed state, has avoided to a certain extent backing up of sewage, has solved blockage problem.
2, because this flexible pipe pore is long and narrow, variable-width, the large I of stomatal width changes with the increase and decrease of air demand, can give the certain stirring power of sewage and wash away power when improve oxygen transfer rate, thereby make simple aeration become more diversified.
3, this flexible pipe acid and alkali-resistance, ageing-resistant, do not tear, and the life-span is long, and cost is low.
4, the compressive strength 2kg/cm of this flexible pipe
2, aeration rate 0-15m
3/ hm, air flue is short, and and straight, atmospheric pressure lost is little, and gas distribution is even, and service area is wide, and aeration intensity is large, and without dead angle, coefficient of oxygen utilization and dynamic efficiency are high.
5, this flexible pipe can curlingly be packed, and freight charges are low, install very easy, without gas leakage hidden danger.
6, the applicable scope of this flexible pipe: various industrial organic waste waters, municipal wastewater and sanitary sewage, and industrialization culture fishery.
