Abstract
The utility model discloses an improvement of a tubular rubber film aerator, especially relates to the arrangement of a micropore of an aeration membrane tube. the utility model is characterized in that the aeration micropore is arranged on the upper semi-hemicycle of the aeration membrane tube and at lease one row of aeration pores or concave gas tracks are arranged on the lower semi-hemicycle of the suspension pipe.
Description
Technical field
Utility model is about the improvement to tubular type rubber diaphragm aerator, relates in particular to the improvement of aeration film pipe.
Prior art
Chinese patent 01229706 disclosed tubular membrane aerator, be to have aerating pore at whole circular aeration film pipe side face, this aerator is when aeration, especially bottom aeration bubble meeting and collision of upper half aeration bubble generation in uphill process of lower half, cause the microbubble contact-impact to become air pocket, the advantage of micro-hole aerator can not be not fully exerted, and causes bubble inhomogeneous on the contrary, influences aeration efficient.Secondly, tube aerator adopts in gas-distribution pipe one end air inlet usually, and pressure air is carried to extreme direction not by the diaphragm that lifts, easily causes aerator not hold the air feed deficiency, and whole aeration tube distribution is inhomogeneous, also can influence aeration efficient.Besides, existing aerator aeration pipe block head is not held at aeration tube, be full of pressure air in the whole aeration tube during aeration, can produce big buoyancy and strong shake, not only cause loosening gas leakage between aeration tube and main air-supply duct easily, aeration tube is fractureed in the junction, and the aeration tube shake also can cause aeration bubble hit thixotroping polymerization, influence aeration efficient, and require all higher aeration tube, the air feed person in charge and fixed support etc.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of improved aeration bubble to be difficult for the thixotroping polymerization, and bubble is fine and closely woven evenly, and gas distribution is even, the tubular membrane aerator that aeration is effective.
Substantially do not have buoyancy when another purpose of utility model is to provide a kind of aeration and produce the tubular membrane aerator of not shaking during work.
Utility model first purpose realizes, the main improvement is that rubber aeration film pipe aerating pore only is opened in film pipe upper half, to the air supply trough that is provided with aeration round or indent, to aeration film pipe air feed, reach even gas distribution at film tube support pipe lower half over glaze by axial round or air drain.Specifically, utility model tubular membrane aerator comprises the elasticity aeration film pipe that has micropore, and aeration film tube support pipe, it is characterized in that aerating pore opens at aeration film pipe upper half, said support tube lower half over glaze is to having a row's aeration through hole or an indent air drain at least.For more effective aeration bubble generation that prevents collides, increase aerating pore quantity again to greatest extent, utility model aerating pore perforate angle is the best with the 120-170 degree.According to the utility model design, film tube support pipe can be hollow, also can be solid, decides on the side face plenum system, as adopting aeration round air feed, then adopts hollow circular tube; As adopt indent air drain air feed, also can adopt solid tubes.Air feed round and indent air drain quantity are looked the aerator caliber, can be one, also can many, or both are used in combination.
Another purpose of utility model realizes, mainly improves as adopts blank pipe to make support tube, and its block head is arranged on the aeration tube central region, and the aeration tube internal cause partly is full of water body like this, thus the deficiency that generation buoyancy brings when effectively preventing aeration.The said plug of utility model is arranged on the aeration tube central region, and the absolute medium position on the non-exponential meaning, can depart to the left and right according to the aeration caliber, not produce buoyancy simultaneously as far as possible to not holding skew for good.
Utility model especially is controlled at 120-170 degree scope because aeration film pipe micropore is arranged at the pipe upper half, and bubble can not come in contact collision substantially during aeration, thereby bubble is fine and closely woven evenly, oxygen transfer rate and dynamic efficiency height, and energy consumption is low.Round and/or air drain air feed gas distribution are even, efficiently solve not hold the insufficient shortcoming of air feed, help giving full play to the aeration efficient of whole aeration tube, and aeration is effective.The hollow tube block head is arranged on the aeration tube central region, basically eliminate the buoyancy effect during aeration, prolonged aerating system work-ing life.
Description below in conjunction with two indefiniteness embodiment further specifies utility model.
Description of drawings
Fig. 1 is an embodiment tubular membrane aerator structural representation.
Fig. 2 is embodiment 1 Figure 1A-A sectional structure synoptic diagram.
Fig. 3 is second embodiment Figure 1A-A TV structure synoptic diagram.
Embodiment 1: referring to Fig. 1,2, tubular type rubber diaphragm aerator, comprise hollow aeration support tube 2, fit over the outer rubber aeration membrane 1 of support tube, the anti-clip 5 that loses heart in two ends, aeration tube block head 3 is located at the middle part and departs from inlet end 6 zones, and the support tube bottom axially has air feed round 4, aerating pore is opened at aeration film pipe upper half, and the perforate angle is 150 degree.
Embodiment 2: referring to Fig. 3, as embodiment 1, wherein air feed adopts the indent air drain 7 that is located at the support tube bottom.
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, and have many as air supply trough or round, or are arranged on the lower half side; and adopt solid supporting pipe etc., still truely use novel protected scope.
Claims (5)
1, a kind of tubular membrane aerator comprises the elasticity aeration film pipe that has micropore, and aeration film tube support pipe, it is characterized in that aerating pore opens at aeration film pipe upper half, and said support tube lower half over glaze is to having a row's aeration through hole or an indent air drain at least.
2,, it is characterized in that said aerating pore perforate angle is the 120-170 degree according to the described tubular membrane aerator of claim 1.
