A lining pipe is arranged in the air distribution pipe, the center of the lining pipe is a water penetrating hole, the inner end of the lining pipe is sealed and the outer surface of the lining pipe is provided with at least one ventilation groove. The ventilation grooves are recessed at the surface of the lining pipe along a longitudinal direction, a ventilation gap is arranged between the lining pipe and the air distribution pipe, the outer end of the lining pipe is provided with a three-way joint, and the three-way joint is connected with the lining pipe. In the use process of the buoyancy free lifted pipe type aerator, resistance when gases enter the aerator is obviously reduced and the efficiency of the aerator can be increased. Simultaneously, the aerator can be integrally lifted to the liquid surface of an aeration tank to be repaired and replacing operation is very convenient.

Description

No buoyancy can promote tube aerator

Technical field

The utility model relates to a kind of oxygenation dispersion device that is applied to oxygen system in the water, especially for the aeration aerating device of sewage disposal.

Background technology

When biochemical process is disposed of sewage, the dissolved oxygen of foot can be provided, be the key that improves biochemical treatment effect and economic benefit.From late nineteen eighties, China begins micro-hole aerator is developed research.Enter the practical stage at present, in engineering is used, saved a large amount of energy, become a kind of more satisfactory aerator.But it exists the bigger difficult problem of buoyancy, must aerator be fixed on the bottom, aeration tank by fastening piece during use.

Chinese patent 00259578.8 provides a kind of " no buoyancy tube-type micropore aerator ", and it comprises inlet suction port and rubber cloth tracheae, and the end of inlet suction port is connected with web member, the sidepiece of the web member bushing pipe that is being connected, and the rubber cloth tracheae is enclosed within on bushing pipe and the web member.Gas enters gap between bushing pipe and the rubber cloth tracheae through inlet suction port.Then, gas just the micro-through-hole from the rubber cloth tracheae enter the aeration tank.Simultaneously, after the water in the aeration tank entered bushing pipe, whole aerator just can not float voluntarily.So just, solved the shortcoming that aerator can float.But in above-mentioned aerator, supplied gas mobile gap is too little between bushing pipe and the rubber cloth tracheae, and in use energy consumption is higher to cause aerator, and the working cost of aeration tank is many.

Summary of the invention

The purpose of this utility model is at the existing the problems referred to above of existing aerator, provides a kind of no buoyancy can promote tube aerator, makes it have energy consumption characteristics low, simple and reasonable, easy to maintenance.

The purpose of this utility model can realize by following technical proposal: this nothing buoyancy can promote tube aerator and comprise inlet suction port and gas distribution pipe, gas distribution pipe is connected and communicates with inlet suction port, bushing pipe is loaded in the gas distribution pipe, the center of bushing pipe is the limbers, its inner sealing is characterized in that described bushing pipe outside surface has a vent grooves at least, vent grooves is longitudinally recessed in liner surface, leaves airspace between bushing pipe and gas distribution pipe.

This nothing buoyancy can promote the inlet suction port of tube aerator and the gas distribution pipeline of aeration tank connects.Vent grooves, airspace all communicate with inlet suction port.Gas in the gas distribution pipeline enters vent grooves through inlet suction port, and gas vent grooves along the longitudinal diffuses in the airspace, at last aeration and going out the micropore from gas distribution pipe.

Can promote in the tube aerator at above-mentioned no buoyancy, it is that material is made that described gas distribution pipe adopts rubber.

Can promote in the tube aerator at above-mentioned no buoyancy, described bushing pipe outer end is provided with Y-junction, and Y-junction links to each other with bushing pipe, and Y-junction is provided with the water entry that communicates with the bushing pipe limbers.

Just a plurality of rubber cloth tracheaes and bushing pipe can be bound up by Y-junction, make a plurality of gas distribution pipes aerations and going out simultaneously.Simultaneously, water enters in the limbers of bushing pipe from water entry, and aerator can not floated voluntarily.

Compared with prior art, can promote in the tube aerator at no buoyancy of the present utility model, gas at first enters the bigger vent grooves in space from inlet suction port, and then diffuse in the whole airspace from vent grooves, the resistance that gas enters aerator obviously reduces, can reduce the energy consumption of air inlet, improve the efficient of aerator.Simultaneously, utilize pipe fitting such as Y-junction that a plurality of gas distribution pipes are bound up, increased the bulk strength of aerating system, can prolong the work-ing life of aerator, reduce the cost of aeration tank; In addition, in use occur damaging as certain gas distribution pipe, aerator integral body can be risen to the aeration tank liquid level and keep in repair, reduce the common aerator shortcomings such as the inconvenience that brought of maintenance and workload are very big that need discharge water, change like this operate just very convenient.

Embodiment

As shown in Figure 1, this nothing buoyancy can promote tube aerator and comprises parts such as inlet suction port 1, gas distribution pipe 2 and bushing pipe 3.In the present embodiment, inlet suction port 1 is a Y-junction.One end of inlet suction port 1 is connected on the gas distribution pipeline, and two ends are connected with gas distribution pipe 2 respectively in addition.Air inlet port 11 is arranged in the inlet suction port 1, and air inlet port 11 communicates with gas distribution pipe 2.In the present embodiment, inlet suction port 1 is fastened on gas distribution pipe 2 on the inlet suction port 1 by anchor ear 6.

In the present embodiment, it is that material is made that gas distribution pipe 2 adopts rubber.Exist small solarization air cap on gas distribution pipe 2, gas comes out from these solarization air caps.As shown in Figure 2, two road vent grooves 32 on the bushing pipe 3, vent grooves 32 is positioned at the both sides of bushing pipe 3, and it is recessed along the longitudinal on the surface of bushing pipe 3.The center of bushing pipe 3 is limbers 31, inner sealing.Bushing pipe 3 is contained in the gas distribution pipe 2, forms a supplied gas mobile airspace 4 between them.Air inlet port 11 in the inlet suction port 1 does not communicate with limbers 31, but communicates with vent grooves 32 and airspace 4.

As shown in Figure 3, can be linked together by Y-junction 5 between each gas distribution pipe 2.In the present embodiment, Y-junction 5 is the outer ends that are fixed on bushing pipe 3.A water entry 51 is arranged on the Y-junction 5, and water entry 51 communicates with the limbers 31 of each bushing pipe 3 that is connected.
