Abstract
The utility model relates to an air distributing type blowing aerator which is device for filling air into water to increase the oxygen content of water. The utility model is mainly composed of an aerator body, wherein, the aerator body is respectively connected with an air inlet pipe and an air gas diffusion disk, and the an air distributing chamber is arranged in the aerator body. The utility model is characterized in that a plurality of air distributing units composed of air distributing bodies and micropore air diffusion membranes arranged on the air distributing bodies are arranged on the aerator body, and the air distributing units are communicated with the air distributing chamber. The utility model has the advantages of uniform aeration, large aeration area, high oxygen utilization rate, low energy consumption, long service life, etc.
Description
A kind ofly in water, charge and discharge air, improve the air-distributing blast aeration device of water oxygen level.
Existing gas diffusion membrane blast aeration device is by the aeration body, and whole micropore gas diffusion membrane connects to form by diffusion disc and aeration body.Its weak point is, because whole micropore gaseous diffusion membrane area is big, under the pressure effect of air blast, diffusion barrier makes the micro-pore aeration amount of diffusion barrier middle part big to outer lug, and the micropore of periphery is because of distortion, and aeration rate is little or aeration not, causes the diffusion barrier aeration inhomogeneous, and actual aeration area is little, the utilization ratio of oxygen is low, the energy consumption height; Because in use, diffusion barrier often is out of shape and damages, and work-ing life is low.
The purpose of this utility model is, provide a kind of by several minutes the gas unit form, aeration is even and area is big, the oxygen utilization rate height, energy consumption is low, the air-distributing blast aeration device of long service life.
The purpose of this utility model is realized by following technical scheme: a kind of air-distributing blast aeration device, it comprises: aeration body (1), aeration body (1) is connected with gaseous diffusion dish (4) with admission passage (3) respectively, plenum chamber (2) is set in aeration body (1), it is characterized in that: also be included in aeration body (1) and go up setting by minute gas (5), divide to be equipped with several minutes gas unit that micropore gas diffusion membrane (7) is formed on the gas (5), several minutes the gas unit all be communicated with plenum chamber (2).
Air-distributing blast aeration device of the present utility model is compared with existing gas diffusion membrane blast aeration device, because the utility model adopts by minute gas, on minute gas, be equipped with several minutes gas modular construction that the micropore gas diffusion membrane is formed, big area diffusion barrier by prior art becomes several small area diffusion barriers, under the pressure of blast effect, the distortion of small area diffusion barrier is very little, so, aeration is even, though the diffusion barrier area is less relatively, and actual aeration area is relatively large, has the oxygen utilization rate height, energy consumption is low, advantages such as long service life.
The utility model is described in further detail below in conjunction with embodiment shown in the drawings.
Fig. 1 is the structure cross-sectional schematic of air-distributing blast aeration device.
Fig. 2 is the schematic top plan view of Fig. 1.
With reference to Fig. 1 and 2, air-distributing blast aeration device is by aeration body (1), plenum chamber (2) is set in the aeration body (1), one end of aeration body (1) is connected with admission passage (3) by joint, the other end is threaded with gaseous diffusion dish (4), goes up uniform several minutes gas (5) that is provided with at aeration body (1), divides on the gas (5) to be equipped with micropore gas diffusion membrane (7), be threaded with dividing gas (5) with back of the body cap (6), micropore gas diffusion membrane (7) is fixed on the branch gas (5).Aeration body (1) is used injection molding.Back of the body cap (6) is used injection molding.Micropore gas diffusion membrane (7) is made by polyester fiber net etc.
During work, air after the air blast (3) by the road enters the plenum chamber (2) of air-distributing blast aeration device, with even air be assigned in the gaseous diffusion dish (4), enter several minutes gas (5) through diffusion disc (4) again, form micro-bubble through micropore gas diffusion membrane (7) and be diffused in the water, finish oxygenation water.
