Description

Aerating apparatus

Technical field

The utility model aerating apparatus is the biological treating equipment that is used for tap water and sewage disposal, in particular for the aerating apparatus of water body oxygenation, belong to the environmental protection equipment field.

Background technology

For the water body oxygenation is a gordian technique in the sewage aerobic biological chemistry treatment process.In the biochemical method of water treatment, one of applied major equipment of aerobic activated sludge process is an aerating apparatus.In the prior art, aerating apparatus adopts fixed mounting means more, and promptly aerator installs and fixes under water the air line.Because the underwater position of aerator is a limitation changeless, that add plate-type aerator configuration itself, above-mentioned aerating apparatus causes oxygenation inhomogeneous unavoidably, too high and can produce eddy flow and make gas residence time of ducking in drink too short near the oxygenation of aerator part, therefore oxygen-transfer efficiency is lower, and in case the maintenance difficult that breaks down.Through picking up rope: 98204611.1 " a kind of floated microporous aeration devices ", be characterized in that described micro-hole aerator is the film tube type aerator of oval column type, its internal layer for be communicated with ventpipe and tube wall on the stereoplasm tube of several open-works is arranged, this stereoplasm tube outer tightly around be wrapped in one deck soft, resilient plastics or gum sleeve, be evenly distributed with several are closure state under non-ventilation situation micropore on the described sleeve pipe; Micropore on the aerator sleeve pipe is the micropore of cruciform otch; " 03209634.8 a kind of suspension chain type aerating apparatus ", this film tube type aerator, bright its internal layer for be communicated with ventpipe and tube wall on the stereoplasm tube of several open-works is arranged, this stereoplasm tube outer tightly around be wrapped in one deck soft, resilient plastics or gum sleeve, be evenly distributed with several are closure state under non-ventilation situation micropore on this sleeve pipe; It is that gas is pressed into " stereoplasm tube is outward tightly around being wrapped in the soft film of one deck " realization aeration performance that each environmental protection unit's great majority is used film tube type aerator, fatal shortcoming, the pressure inequality, and mantle easily drum is broken.

Summary of the invention

The purpose of this utility model provides a kind of material and replaces soft film, aerating apparatus simple in structure, that the life-span is long, coefficient of oxygen utilization is high.

The purpose of this utility model is realized by following scheme.

Aerating apparatus is made up of aeration tube, counterweight, elbow, and aeration tube is made up of skeleton, microporous pipe, and skeleton outer end and microporous pipe inwall are fitted; Aeration tube is exactly a microporous pipe; The microporous pipe material is high-molecular polythene, polypropylene tube; High-molecular polythene, polypropylene tube are for sintered pipes or melt and spray pipe; Single tube aerating apparatus two-end structure symmetry; The one end structure is: screw thread is fixedlyed connected between aeration pipe end and the counterweight; The aeration tube termination is communicated with short circuit by nut and seal washer, between bonding; Be communicated with between the short circuit the other end and the elbow, elbow is communicated with by short circuit, short circuit the other end gas-filled valve to be connect.

The utility model effect is very outstanding: enter air in the water by micropore aeration pipe, can fully contact the coefficient of oxygen utilization height with water, can reach more than 25%, compare economize on electricity more than 30% with the traditional aerator that uses, the polyethylene sintered pipes can carry out back flushing, long service life.

Embodiment

Each element brief introduction among the figure:

Aeration tube 1: material is by the waterproof anticorrosive material; Counterweight 2: material is cast iron, carbon steel or stainless steel; Fitting nut 3: material is an ABS plastic; Interior short circuit 4: material is an ABS plastic, standard tubing short circuit; Elbow 5: material is an ABS plastic; Outer short circuit 6: carbon steel or stainless steel pipe; Seal washer 7: RUBBER O RunddichtringO; Suspension ring 8: carbon steel or stainless steel standard part; Support 9: carbon steel or stainless steel, weldment; Union lever 10: carbon steel or stainless steel, machined piece; Threeway 11: material is carbon steel or stainless steel, standardized component.

According to sewage disposal Aerobic Pond size, structure and sewage different in kind, the aeration tube assemble method divides patterns such as single tube, two-tube and multitube, is called as single tube aerating apparatus, two-tube aerating apparatus, multitube aerating apparatus respectively, and structure is seen accompanying drawing.

Fig. 1 is the two-tube aerating apparatus that 2 aeration tubes compose in series, its structure is: two aeration tube 1 adjacent two ends are fixed together by support 9, two aeration tubes, 1 outer end sidewall is connected with left and right sides counterweight 2 respectively, two aeration tubes, 1 external port fixedly is communicated with interior short circuit 4 by nut 3, two interior short circuit 4 the other ends are communicated with two elbows 5 respectively, two elbows 5 are communicated with outer short circuit 6 again, and the external port of outer short circuit 6 is communicated with the gas-filled valve of waiting to connect peripheral hardware respectively; For the aeration tube 1 of reinforcing two polyphones fixedly connected by union lever 10 between left and right sides counterweight 2; In order to add sealing-ring 7 between enhanced leaktightness two aeration tubes, 1 external port and the nut 3; Establish suspension ring 8 on the counterweight 2.

Well imagine that by Fig. 1 the single tube aerating apparatus is only established an aeration tube 1, that is to say the support in the two-tube aerating apparatus 9 is dismantled that union lever 10 also can be dismantled; Only the dead end sidewall sheath of aeration tube 1 is assembled heavyly by 2, the dead end mouth of aeration tube 1 fixedly is communicated with interior short circuit 4 by nut 3 and seal washer 7, be communicated with elbow 5, outer short circuit 6 again and get final product.

Fig. 2 is that four tube aeration devices are placed in-line two-tube aerating apparatus to be together in parallel again to form on two-tube aerating apparatus basis, oneself placed in-line two-tube aeration tube 1 in parallel again on support 9 only, again with Y-tube 11 of its two pipe outer end elbow 6 changing-overs, Y-tube 11 blank pipe heads wait to connect gas-filled valve promptly becomes four tube aeration devices, in like manner two-tube aerating apparatus also can be handled like this, or manages and even form by four; The multitube aerating apparatus is to be formed in parallel on the basis of double-tube series aerating apparatus or directly to be formed in parallel by multitube.

Fig. 3, Fig. 4 can find out that aeration tube 1 is made up of microporous pipe 1-1 and skeleton 1-2, and skeleton 1-2 is a torus, not only support aeration tube 1 but also ventilate, and the material of microporous pipe 1-1 is polyethylene, polypropylene, are divided into sintered pipes and melt and spray pipe, micropore size 5-500um; Be not with the skeleton list can with microporous pipe yet.
