Abstract

The utility model relates to an improved tubular membrane aerator, in particular to the improvement of the gas distribution and connecting device of an aeration machine. The utility model is characterized in that the axial direction that the aeration machine bears a round tube circular face is provided with at least an inner concave gas groove and is crossly connected with an air supply main tube through a central connecting tube, thereby overcoming the deficiency caused by the bearing tube taking as the air supply tube with no shake in operation. And the utility model has the advantages of long service life, no seeper in the air tube, high aeration efficiency, firm and convenient installation, no air leakage of the joint and convenient disassembly.

Description

A kind of improved tubular membrane aerator
Utility model is about the improvement to tubular type rubber diaphragm aerator, relates in particular to the distribution of aerator and the improvement of coupling device.
Tubular type rubber diaphragm aerator is made up of rubber tube aeration membrane that has micropore and supporting diaphragm pipe, because aeration rate is big, and the suffered tension force of diaphragm is littler than plate-type aerator, thereby obtains pay attention to day by day in water treatment.Known tubular type rubber diaphragm aerator, be on the diaphragm support pipe, to have pore, the supporting pipe is the double as air-supply duct simultaneously, pressure air enters between aeration membrane and supporting pipe by reaching pore in the supporting pipe, between supporting diaphragm pipe and aeration membrane, form the annular working air chamber, diaphragm is heaved leave the supporting diaphragm pipe of applying, but pressure air is then by the outside aeration of Zhang Weikong on the diaphragm.Aeration stops, and diaphragm shrinks back to tighten up under the screen resilience effect and is attached to diaphragm support pipe surface.The main deficiency of this tubular membrane aerator is that the diaphragm support pipe is again an air-supply duct simultaneously, is full of pressure air in it, makes aeration tube produce buoyancy.The buoyancy of aeration tube can make aeration tube produce strong shake when aeration is worked.The shake of aeration tube, the one, cause easily between aeration tube and main air-supply duct and leak gas, influence aeration efficient, the 2nd, the aeration arm ruptures easily, the 3rd, air-supply duct is in case discharge than difficult after the water inlet, can influence aeration efficient well, therefore, this tube aerator is responsible for by aeration tube, air feed and fixed support is had relatively high expectations.
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of improved no buoyancy to produce, and does not shake during work, and water body is difficult for entering the tubular membrane aerator of air flue.
The utility model purpose realizes that main the improvement is the air supply trough that axially is provided with indent at diaphragm support pipe side face, and by narrow and small air drain air feed between aeration membrane and supporting pipe, and no gas is full of water body in the support tube, thereby has stoped the buoyancy generation.Specifically, utility model tubular membrane aerator comprises the elasticity aeration film pipe that has micropore, and aeration film tube support pipe is characterized in that said supporting pipe side face axially has an indent air drain at least.Utility model is owing to change the support tube air feed into narrow and small indent air drain air feed, reduced the air feed volume greatly, be full of water body in the supporting pipe, so aeration tube does not have the buoyancy generation substantially and make, simultaneously, the less water body that also can not take place in line style air drain space flows backwards and to enter air drain.According to the utility model design, said diaphragm support pipe can be hollow, also can be solid, uses material for saving, and is excellent with hollow circular-tube especially.
For ease of the processing assembling, the utility model aeration tube, a kind of preferred version is made up of left and right sides aeration tube and intermediate connector plug-in unit.Connecting plug-in unit one is to play with the air feed person in charge to fixedly connected, the 2nd, air feed main pipe pressure air is provided and delivered to aeration tube.
Below in conjunction with an indefiniteness embodiment, further specify the utility model structure.
Fig. 1 is an embodiment tubular membrane aerator structural representation.
Fig. 2 is Figure 1A-A sectional structure synoptic diagram.
Fig. 3 is that the embodiment aeration tube is connected the dongle configuration synoptic diagram with the air feed person in charge.
Fig. 4 is the user mode synoptic diagram.
Embodiment: referring to accompanying drawing, tubular type rubber diaphragm aerator, comprise left aeration tube, connect plug-in unit and right aeration tube, aeration tube is by aeration film tube support circle blank pipe 2, the rubber aeration film pipe 6 of Bao Meng band micropore on the supporting pipe is formed, aeration film pipe two ends have clip 1 that the film tube end is tightened on support tube, and the support tube periphery axially has the obstructed air supply troughs 7 in indent two ends (making air drain at the bottom of the pond during installation), aeration film pipe except that with the air supply trough correspondence position be processed with and can open aerating pore.Connect plug-in unit 8 two ends step 9 is arranged, for socket joint left and right sides aeration tube, connect the plug-in unit middle part inner concave arc surface 10 is arranged, the valve 11 of protrusion is arranged on it, inner concave arc surface and air feed are responsible for cross-lap joint, form firm joint face, and are fixed on the air feed person in charge by anchor ear 4 obvolvents, protrude valve and air feed and be responsible for the formation gas passage, and communicate with the socket aeration tube air drain and the air feed person in charge respectively by air flue 12.The air feed person in charge is fixed at the bottom of the pond by adjustable support 5, forms the aeration network.
During aeration, pressure air is responsible for by air feed and is entered the aeration tube air drain by pipe connecting, forms ring-shaped air chamber between aeration film pipe and supporting pipe, and aeration film pipe is heaved, but air leads on the filmed passing tube Zhang Weikong to the water body aeration.Stop air feed, the film tubular elastic shrinks to be held tightly on support tube, and also closed pore adds air drain position film pipe pore-free to micropore with the resilience contraction, therefore stops water body to flow backwards and enters air drain.
The utility model concrete structure is not limited to the foregoing description; some do not depart from the unsubstantiality change that the utility model design is done; still truely use novel protected scope; comprise that the aeration tube air supply trough is provided with two or many; adopt solid supporting pipe, the butt joint of the Hough of pipe connecting is with the mode of connection of aeration tube (as pegging graft or be threaded etc.); the specific form of air flue, film pipe are tightened the unsubstantiality change of mode or the like.
Utility model is provided with the less vertical air drain in space because the support tube air feed changed on support tube, and to the connection plug-in unit of air drain air feed, makes aeration tube not have buoyancy and produce, and because of air supply space is less water body can not take place and flow backwards.Have simple in structurely, operation can not shaken, long service life, and no ponding in the tracheae, aeration efficient height, it is firmly convenient to install, and interface is difficult for leaking gas convenient disassembly.
