Abstract

The utility model relates to a sewage treatment facilities; a tube rubber variable fine bubble diffusion aerator is disclosed, which comprises an open connection, a lined pipe, a rubber diaphragm pipe with I-shaped variable bubble, an S clamp and a union pipe. A plurality of fine bubbles are arranged on the wall of the aeration rubber tube (8), the rubber tube (8) is installed outside of the lined pipe (7), both ends of the rubber tube (8) are clamped tightly with the tube clamp (9); the lined pipe and the union pipe are connected with open connection. Compared with the existing aerator, the utility model has the following characteristics: 1. The expansion curve of variable fine bubble rubber tube during aeration coincides with the arc of S section clamp, so stress concentration of rubber tube while expanding during the course of aeration can be avoided, and service life of tube aerator is greatly improved. 2 . With the design of open connection, the lined pipe and the water body are intercommunicated without buoyancy, therefore deformation can be avoided. 3. Special I-shaped through fine bubbles are arranged on the rubber diaphragm, so the resistance of aeration can be reduced, tearing of fine bubbles can be prevented; even air distribution and receiving can be achieved during aeration without deformation; when the air supply stops, the rubber tube shrinks to seal the upper air outlet of the lined pipe, the I-shaped variable bubble closes, and double water stop result can be gained.

Description

The variable mipor rubber menbrane aerator of tubular type

Technical field

The utility model relates to sewage treatment facility equipment, is a kind of aerator.

Background technology

In numerous methods of sewage disposal, aerobe handle be a kind of be economy effective means again.The factor that influences the aerobe treatment effect is a lot, and one of wherein important factor is in the sewage sufficient dissolved oxygen to be arranged, and aerator is the key device of oxygen supply in sewage.It plays oxygen supply, mass transfer, stirring and blended vital role in water treatment process, its efficient just is directly connected to the treatment effect and the working cost of whole water treatment system.Therefore, in decades, the technological development and the innovation of this kind equipment is devoted in countries in the world always.Domestic research and the application that begins to carry out this respect from the seventies.Originally be the boring aeration device, the aperture reaches more than the 3mm, belongs to the macropore aeration, and gas distribution is inhomogeneous, and the utilization ratio of oxygen is low, easily causes local aeration dead band.Early eighties is developed disc type sintered ceramic micro-hole aerator, and the aeration effect is obviously improved, and the structural strength of gas distribution material and corrosion resistance enhancing, but offer micropore owing to adopt the sintered ceramic technology, belong to the rigidity opening, lamina membranacea thickness is big, and the micropore air flue on the lamina membranacea is long and to be the little production well of air inlet port big, to pass through dust removal process earlier to source of the gas, easily by sludge blockage, water body easily takes place and pours in down a chimney in mud easy-clear not in the hole when stopping the supple of gas or steam during operation, therefore, domestic less use at present.The early 1990s is brought into use rubber diaphragm disc type micro-hole aerator, and no matter this series products is in the aeration effect, still coefficient of oxygen utilization, and dynamic efficiency aspect all have clear improvement.In recent years, begin one's study again in the industry and use tubular type rubber diaphragm aerator.But the major defect that the rubber diaphragm aerator that research is at present used exists is in aeration process, the rubber diaphragm at snap ring place is the weakest position, rubber diaphragm expand to produce stress concentration, in expansion process repeatedly and produce tired tearing failure, has reduced the work-ing life of aerator.

The utility model content

The purpose of this utility model is to provide a kind of improved tubular type variable mipor rubber menbrane aerator, and it can overcome deficiency of the prior art.

The utility model is realized in the following way:

The variable mipor rubber menbrane aerator of a kind of tubular type, it is characterized in that its structure is made up of open joint, internal lining pipe, aeration rubber diaphragm pipe, air feed pipe connecting and pipe clamp, have many micropores on the tube wall of aeration rubber diaphragm pipe, the rubber diaphragm pipe box is loaded on outside the internal lining pipe, tightens with pipe clamp at the two ends of rubber diaphragm pipe.With open joint internal lining pipe is connected with the air feed pipe connecting,

The diameter of described open joint is suitable with the internal diameter of internal lining pipe, be used to connect internal lining pipe, the middle part of open joint has the closed tracheae connecting hole of an end that is connected with air-supply duct, joint wall place outside the tracheae connecting hole vertically also has some through holes, near the bottom of tracheae connecting hole, have the horizontal pore of outside connection, laterally pore is not communicated with through hole, the air feed pipe connecting is inserted in the tracheae connecting hole of open joint.

Described internal lining pipe is a straight pipe, and an end installed inside of internal lining pipe connects open joint, and internal lining pipe has production well corresponding to the horizontal pore place of open joint.

Further design is that the micropore of opening on the tube wall of aeration rubber diaphragm pipe is I-shaped micropore.

Further design is that the section of pipe clamp is a S shape.

During use, the air feed pipe connecting is connected to air supply source, and said structure sunk in the liquid of wanting aeration, air feed enters into open joint from the air feed pipe connecting, enters into gap between internal lining pipe and the rubber diaphragm pipe from horizontal pore, because the rubber diaphragm pipe is flexible, under the effect of supply gas pressure, the rubber diaphragm tube swelling, air feed discharges from the micropore of rubber diaphragm pipe, gives the liquid aeration at its place.

In addition, when said structure being sunk in the liquid of wanting aeration, liquid enters in the internal lining pipe from the through hole of open joint, makes full of liquid in the internal lining pipe, can significantly reduce the buoyancy of aerator like this.

With accompanying drawing the utility model is further described below.

Embodiment

As shown in Figure 7, the variable mipor rubber menbrane aerator of a kind of tubular type that the utility model provides, it is made up of open joint 1, internal lining pipe 7, aeration rubber diaphragm pipe 8, pipe connecting 6, S shape section pipe clamp 9,

The internal diameter of the diameter of described open joint 1 and internal lining pipe 7 is suitable, be used to connect internal lining pipe 7, the middle part of open joint 1 has the closed tracheae connecting hole 11 that is connected with air-supply duct 6, joint wall place outside tracheae connecting hole 11 vertically also has some through holes 13, have the horizontal pore 12 of outside connection in the bottom of tracheae connecting hole 11, laterally pore 12 is not communicated with through hole 13.

Described internal lining pipe 7 is a straight pipe, and an end installed inside of internal lining pipe 7 connects open joint 1, and internal lining pipe 7 has production well 72 corresponding to horizontal pore 12 places of open joint 1.

Have many I-shaped micropores on the tube wall of aeration rubber diaphragm pipe 8, rubber diaphragm pipe 8 is set in outside the internal lining pipe 7, with S shape section pipe clamp 9 it is clamped in the two ends of internal lining pipe 7 at the two ends of rubber diaphragm pipe 8.

An application example as shown in Figure 8, pipe connecting 6 is passed main air-supply duct 10, and in its two ends sealing member 4 sealing and fixing, the middle part of pipe connecting 6 has air vent 5, pipe connecting 6 is communicated with main air-supply duct 10, again the two ends of pipe connecting 6 is inserted in the open joint 1 above-mentioned aerator connection.
