Abstract
The utility model relates to a membrance hole of a membrance aerator and is a combined vent hole that can be automatically opened and closed. The structure of the membrance vent hole of a present membrance aerator has a common technique characteristic of single linear hole and has the disadvantages that: firstly, two ends of the single linear hole certainly tend to be torn, and secondly, only the membrance is under pressure and swells outside as a whole, the single linear hole can be opened for ventilation. To resolve the problems that severely trouble the effect of aeration membrances, the utility model provides an 'I' shaped combined hole, the hole consists of a horizontal linear hole, the end of which is connected with two vertical linear holes, the two sides of horizontal line form two pieces of symmetric structure that can produce subtle motions. The air is mainly discharged through the horizontal linear hole, and the two vertical holes stop the two ends of the horizontal line from tending to be torn. Since the vent hole is two pieces of symmetric structure that can produce subtle motions, the ventilation by swelling and opening the hole under pressure of the membrance as a whole is changed into self-motion ventilation of the hole, thus decreasing the resistance force and fatigue of the membrance.
Description
Affiliated technical field
But the utility model relates to a kind of opening and closing venting hole of diaphragm type aerator diaphragm-operated that is used for sewage biochemical treatment aeration system.
Background technology
At present, known diaphragm type aerator diaphragm venting hole all is that in-line, curved shape, dihedral, half garden shape etc. are several, though the shape in these holes is different, the structure in hole has a common technical characteristic, promptly all is the single line hole.Each single line hole in the diaphragm certainly exists two and easily tears end, and Here it is influences the major hidden danger in diaphragm reliability and life-span.The single line hole also has a serious problem to be, has only the whole pressurized of diaphragm outwards to expand, and exhaust can be opened in the single line hole in the diaphragm, and this has just increased the diaphragm resistance of exhaust with tired.
Summary of the invention
Exist and easily to tear terminal and have only diaphragm integral body to be subjected to the pressuring film plate hole can open the deflated defective for overcoming the existing diaphragm type device diaphragm single line hole of exposing to the sun, the utility model provides a kind of I-shaped combination bore, this Kong Youyi horizontal line bore end connects two vertical line holes and forms, and formed two symmetrical structures that can produce tiny action on the both sides of horizontal line.Exhaust mainly is to exclude through horizontal line hole place, easily tears end and horizontal line has been blocked in two vertical line holes; Because venting hole is two symmetrical structures that can produce tiny action, exhaust is opened in the expansion in the whole pressurized of diaphragm hole, change into the exhaust of self moving in hole.
The technical scheme that its technical problem that solves the utility model adopts is: a large amount of I-shaped combination bore by two vertical line holes of a horizontal line bore end binding is set in the diaphragm of diaphragm type aerator; Reach blocking-up and easily tear the purpose that terminal and hole self can opening and closing.
The beneficial effects of the utility model are; That can avoid diaphragm type aerator diaphragm hole easily tears end.By the effect dispersion that exhaust produces power of self opening in diaphragm hole, outwards expand the deflated resistance with tired thereby alleviate the whole pressurized of diaphragm.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the figure of setting of the present utility model
Among the figure, 1. horizontal line hole, 2. vertical line hole, 3. I-shaped combination bore, 4 diaphragms.
Embodiment
In the accompanying drawings, in a large number by the terminal I-shaped combination bore (3) that links two vertical line holes (2) in a horizontal line hole (1), even diaphragm in the diaphragm type aerator spaced apart (4), the diaphragm-operated shape can be spherical crown, flat board or pipe etc.
Claims (2)
1. a diaphragm hole evenly is intervally arranged in the aerator diaphragm, it is characterized in that: the diaphragm hole is I-shaped combination bore.
2. diaphragm according to claim 1 hole is characterized in that: I-shaped combination bore links two vertical line holes by a horizontal line bore end and forms.
