A self-Shen microporous aeration tube
Posted by：admin View count：1132 Published：2015-03-03
A microporous aeration pipe from the sink, characterized aeration tube (1) an inner diameter of 6 ~ 12mm, the aeration tube (1)
There wall (2) on the rows 1 to 3 of a diameter of 0.2 ~ 0.3mm micropores (3), adjacent micropores (3) a pitch of 1.5 ~ 3cm, Each row of micropores (3) in the arrangement direction and the diameter perpendicular to the pipeline. A self-Shen microporous aeration tube I. Technical Field [0001] The utility model relates to an aeration tube, particularly to a microporous aeration pipe from the sink. II BACKGROUND ART [0002] The dissolved oxygen is a necessary condition for the survival of aerobic aquatic organisms, and to protect water aquaculture ponds have Plenty of oxygen, it needs to carry out underwater aeration, aeration microporous tube currently used to load heavy items falling to sink The bottom, and this porous aeration tube pore size of only 20 ~ 30μm, there are disadvantages as aerobics weak, porous volume Susceptible to clogging impurities and water to penetrate the water can not be discharged from the pores of the tube; at the same time when the air input, due to the microporous exposure Wall around the trachea filled pores, making the fans to a single pore aeration tube gas transmission over 50 meters in length, so every 50 meters need to increase air intake and a fan, thus the high construction costs, operation and maintenance complex. III SUMMARY OF THE INVENTION [0003] In response to these shortcomings, the utility model aims to provide a can improve aerobic capacity, gas lengths long, slightly Pore clogging impurities and can not easily be easy seepage discharge pipe from the sink microporous aeration tube. [0004] The utility of new technology content, a self-Shen microporous aeration tube, wherein the aeration tube inner diameter 6 ~ 12mm, is provided in the wall of the aeration tube having a diameter of 1 to 3 rows of pores 0.2 ~ 0.3mm, a pitch of the adjacent micropores 1.5 ~ 3cm, each row of pores of diameter pipelines aligned with the vertical direction. [0005] In the above microporous aeration pipe from the sink, which is mainly composed of the following components: PVC resin, plasticizer, external lubrication Agents, internal lubricants and stabilizers. [0006] In the self-Shen microporous aeration tube spacing of adjacent pores with increasing aeration tube diameter decreases. [0007] The utility model has the advantages are: [0008] 1, the utility model is greater than the density of the aeration tube made of the density of water, since water can sink underwater; in pipeline The larger the aperture wall, so that can not easily be clogged pore impurities in the water, easy seepage discharge tube. [0009] 2, less the utility model pore distribution in the wall, you can meet the needs of aeration, but also make the tube Gas transmission length increases, up to 100 meters, effectively improve power efficiency, reduce the number of fans, and cost savings. IV BRIEF DESCRIPTION [0010] Figure 1 is a schematic diagram of the structure of the utility model. Fifth, the specific embodiments [0011] Example 1 Figure 1 shows a self-Shen microporous aeration tube, characterized by an aeration tube inner diameter 6 ~ 12mm, in The aeration tube 1 is provided on the wall 2 a row of pores having a diameter of 0.2mm 3, adjacent micropores 3 spacing 2cm, the row microporous Aligned with the direction of three vertical diameter gas pipeline. |
