Description

Tool improves the diffusing device of air of tubular type of structure

The utility model relates to the diffusing device of air of tubular type that a kind of tool improves structure.

The diffusing device of air of aerating wastewater groove is to supply waste water oxygen to support microorganism, makes unhelpful material in its food water of decomposition.Existing diffusing device of air is as shown in Figure 1, be with a rubber aeration tube 2 ' in a sealed tube 1 ' external beam, gas follows the ventilating pit 11 ' of sealed tube 1 ' and the air dispelling hole 21 ' of rubber aeration tube 2 ' and outwards flows out after joint 3 ' enters sealed tube 1 ' internal space.Though the diffusing device of air of this kind can obtain average gas flow effect, because during the inner aerification of sealed tube 1 ', buoyancy own is very big, so need fix to prevent rising buoyancy, causes the trouble that fractures and the increase stationary installation is arranged easily.The another kind of improved existing device of air (not shown) that looses then is formed with a vertical chase in an outer surface of tube body, with the rubber aeration tube of conducting gas to the body outside, though this kind structure has solved the problem that buoyancy rises, but too little because of air guide chase and rubber aeration tube contact area, and equal, the diffusing gas indignant about unfairness shortcoming slowly of loosing is arranged, therefore on industry is used, exist and pass the oxygen rate than hanging down and the unsettled problem of utilizing of diffusing gas.

Shortcoming at the prior art existence, the diffusing device of air of the tubular type that provides a kind of tool to improve structure is provided main purpose of the present utility model, go into air-casing head and back pullover respectively have interior scrobicular ring and outer scrobicular ring by the utility model, dispose concentrically ringed interior pipe and outer tube, therebetween the equal baric flow of epoxy air flue is moving so that gas gets, simultaneously has an adapter that takes the shape of the letter U inner sealing by going into the air-casing head, rear sleeve has a centre hole that supplies space outerpace to be connected with interior pipe internal space, for making water can flow into interior pipe internal space, reach and have the double effects that the moving high pass oxygen of equal baric flow and internal and external equilibrium reduce rising buoyancy concurrently, have quick air guide, the industrial utilization of high pass oxygen and less buoyancy.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of tool improves the diffusing device of air of tubular type of structure, include into air-casing head, pullover, the interior pipe in back, outer tube and rubber aeration tube, it is characterized in that: go into air-casing head and back pullover respectively have interior scrobicular ring and outer scrobicular ring, interior pipe is the concentric(al) circles configuration with outer tube, is formed with an equidistant annular air channel betwixt; Go into the air-casing head and have an adapter that takes the shape of the letter U inner sealing, this adapter has through hole and runs through and be communicated in the above-mentioned annular air channel, and the back is pullover to have a centre hole, and interior pipe internal space is interconnected with the pullover space outerpace in back.

Go into air-casing head and back pullover respectively have for interior pipe and outer tube embed the interior scrobicular ring and outer scrobicular ring that is located by connecting, and adapter the inner of going into the air-casing head stretches and manages front end in inserting, interior pipe is provided with communicating aperture in adapter through hole relative position.

The tubular type of improving structure by a kind of tool of the utility model device of air that looses has overcome the shortcoming of prior art, has reached the purpose of above-mentioned creation, the utlity model has that equal baric flow is moving, the effect of high oxygen delivering and air exhausting and the less rising buoyancy of internal and external equilibrium.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Fig. 1 is the longitudinal sectional view of the existing device of air that looses;

Fig. 2 is a stereographic map of the present utility model;

Fig. 3 is a three-dimensional exploded view of the present utility model;

Fig. 4 is a longitudinal sectional view of the present utility model.

See also Fig. 2 to shown in Figure 4, the utility model mainly comprises: go into that air-casing head 1, back are pullover 2, interior pipe 3, outer tube 4 and rubber aeration tube 5.Wherein, go into the two ends that air-casing head 1 and back pullover 2 are socketed on interior pipe 3 and outer tube 4, rubber aeration tube 5 collars are tightened fixing with bundle circle 6 in the outside of outer tube 4 and at two ends, prevent that gas is from rubber aeration tube 5 two ends earial drainages.Above-mentionedly go into air-casing head 1 and have respectively for interior pipe 3 and outer tube 4 and embed the take the shape of the letter U adapter 13 of inner sealing of the interior scrobicular ring 11 that is located by connecting and outer scrobicular ring 12 and, this adapters 13 has at least one through hole 131 (illustrated embodiment is two), and stretches and insert interior 3 front ends of managing; In pipe 3 front end embed in the scrobicular ring 11 of air-casing head 1 and be socketed on and take over 13 outsides both wringing fits and bonding, and be provided with communicating aperture 31 with respect to through hole 131 positions of taking over 13 in front end with antiseep.

Back pullover 2 has interior scrobicular ring 21 and the outer scrobicular ring 22 that supplies interior pipe 3 and outer tube 4 embeddings to be located by connecting respectively equally, and is provided with a centre hole 23 that supplies space outerpace to be connected with the internal space 32 of interior pipe 3.In pipe 3 and the two ends of outer tube 4 by embedding be located by connecting in go into the air-casing head 1 and the interior scrobicular ring 11 of back pullover 2, interior scrobicular ring 21 is concentric(al) circles and disposes with outer scrobicular ring 12, outer scrobicular ring 22, interior pipe and outer tube, and therebetween is formed with an equidistant annular air channel 7.Therefore, gas from adapter 13 inflows of going into air-casing head 1, can follow the through hole 131 of adapter 13 and the communicating aperture 31 of interior pipe 3 and flow in the annular air channels 7, make annular air channel 7 interior aerificatioies, can all press by the ventilating pit 41 of outer tube 4 and the air dispelling hole 51 of rubber aeration tube 5 and outwards flow out.

Because the adapter 13 of going into air-casing head 1 is in the inner sealing, thus gas can't enter in pipe 3 internal spaces 32, back pullover 2 has centre hole 23, can make outside water flow in the internal space 32 of pipe 3, thereby internal and external equilibrium reaches the effect that reduces rising buoyancy.

In sum, the utility model really can solve the problem of the existing device of air that looses, reach have that equal baric flow is moving concurrently, the reenforced effect of high oxygen delivering and air exhausting and the less rising buoyancy of internal and external equilibrium, meet the important document that patent law is stipulated utility application, so propose utility application in accordance with the law.
