Description
Technical field
The present invention relates to a kind of waste disposal plant, especially a kind of aerator, the ring dish-type micro-hole aerator of a kind of improvement specifically.
Background technology
At present, under effect of water pressure, can there is radial necking down in the microbubble stream that the plate-type aerator generally used produces, and the area that bubble is spread reduces, and makes bubble be agglomerated into larger bubble, thus reduces aeration efficiency.People improve diaphragm type dish-type aerator for this reason, Chinese patent " a kind of microporous diaphragm aerator of improvement " (notification number: CN23993838Y, October 4 2010 day for announcing) make aeration membrane and supporting seat into the annular arc-shaped curved surface that there is through water channel at middle part, and for reducing aeration resistance, micropore is made into the hole of Rhizoma Sparganii or many ribs, thus balance the pressure difference of bubble flow by hydraulic pressure effect, reduce in bubble upwelling process because of radial necking down that hydraulic pressure causes, decrease bubble coalescence, improve aeration efficiency.But the bubble produced due to the hole of Rhizoma Sparganii or many ribs is greater than the bubble that point-type micropore produces, and have impact on aeration efficiency.And, if the long-term aeration of this pass, easily tear, reduce the diaphragm life-span.Therefore, design is a kind of just can eliminate necking down, can keep again the micro-hole aerator in diaphragm life-span, to enhancing productivity, will reduce costs and having positive meaning.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide one can eliminate radial necking, unlikely increase aeration resistance, makes the aerator that aeration efficiency improves again.
Technical scheme of the present invention is:
A kind of micro-hole aerator, comprise the supporting disk being provided with air inlet port and the diaphragm be firmly covered on supporting disk, diaphragm is provided with micropore, and described supporting disk is annular curved surface disk body, center hollow out, and is provided with a screw-blade that can horizontally rotate at hollow part.
The sidewall of described supporting disk center hollow part is provided with the annular groove of level, and the end of described screw-blade is installed in this chute, and can rotate along chute under the effect of current flowing through center hollow part.
The inner ring of described supporting disk and edge, outer ring are respectively equipped with cross section and are the interior indent of U-shaped and outer indent, and the inner pressure ring coordinated with described indent and outer press ring.
Described diaphragm is the annular adapted with supporting disk, and its inside and outside edge is pressed in described inside and outside indent respectively by inside and outside pressure ring, and this diaphragm is firmly covered on supporting disk.
Air inlet port on described supporting disk is 2 or multiple, and each air inlet port is all connected with the supporting seat being located at its lower end.
Described each supporting seat is interconnected by pipeline, and is jointly communicated to the saddle rack that is provided with opening; This saddle rack can be erected on air line, and is connected with air line by opening.
The present invention also comprises a U-shaped anchor, can lock mutually with saddle rack, is fastened on air line to make aerator.
Beneficial effect of the present invention:
The present invention is reasonable in design, and structure is simple, easy to use, by the setting of screw-blade, effectively eliminates bubble necking, improves aeration efficiency, and reduce the resistance of aeration membrane, extend the work-ing life of diaphragm, be beneficial to popularization.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figures 1 to 4, the diaphragm 2 that the present invention includes supporting disk 1 and be covered on supporting disk.Described supporting disk 1 is annular curved surface disk body, center hollow out, and the annular groove 12 being provided with level on the sidewall of hollow part.Also be provided with a screw-blade 11 at hollow part, its end is installed in above-mentioned chute 12, and can rotate under the promotion of current.The described inner ring of supporting disk 1 and the edge of outer ring are respectively equipped with interior indent 3 and the outer indent 4 that cross section is U-shaped.The inner pressure ring 5 adapted with it and outer press ring 6 is respectively equipped with in this inside and outside indent.Described diaphragm 2 is the annular adapted with supporting disk 1, which is provided with micropore, and its inside and outside edge is pressed in above-mentioned inside and outside indent respectively by inside and outside pressure ring, and diaphragm 2 is firmly covered on supporting disk 1.The disk body of described supporting disk 1 is provided with 2 air inlet ports 7, also can arrange multiple as required.The lower end of each air inlet port 7 is connected with a supporting seat 8, and is connected with this supporting seat.Be interconnected by pipeline between each supporting seat 8, and be jointly communicated to the saddle rack 9 be positioned at below supporting seat 8.This saddle rack is provided with the opening communicated with above-mentioned pipeline, and make when saddle rack 9 is erected on air line, this opening can be connected with the air outlet on air line, makes the air in air line lead to air inlet port 7 on supporting disk 1.The present invention also comprises a U-shaped anchor 10, and its inward at both ends bends.The end of described saddle rack is provided with outside projection, makes described anchor can catch on this projection and lock, to be fastened on air line by aerator.The locking of this anchor and saddle rack can also adopt other fastening means, as bolt or buckle etc.Described supporting disk 1 and inside and outside pressure ring are all made of plastics, and also can be made up of other analog materials.
During use, first just the saddle rack of this aerator is erected on air line, and the opening on saddle rack and the air outlet on blast main are matched, and makes air flue through.Then use anchor around after air line, with saddle rack butt-joint locking, this aerator is firmly connected with air line.During aeration, the opening of the air in air line on saddle rack, and after the pipeline be attached thereto, arrive the inlet mouth on supporting disk, and form bubble by the micropore on diaphragm.Meanwhile, discharge due to gas and cause water body flow, the screw-blade at supporting disk center is rotated under the promotion of water body, and the water body stirred further above aerator, current are fully mixed with aeration bubbles, avoids producing bubble necking, thus improve aeration coefficient of oxygen utilization.Meanwhile, owing to maintaining circular micropore, avoid and cause diaphragm shortening in work-ing life because of aeration resistance, improve economic benefit.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
