Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 has been described the longitudinal sectional drawing of an embodiment of the present utility model.
Accompanying drawing 2 has been described the scheme of installation of ring slider among the embodiment of the present utility model.
Among the figure: 1. inflation inlet, 2. fixedly end cap, 3. high pressure admission mouth, 4. more than rib tube wall support, 5. annular filter disc, 6. annular slide plate, 7. ring slider, 8. stainless steel band, 9. center push rod, 10. multiedge cylinder, 11. stainless steel springs, 12. positive stop lug boss, 13. movable end covers, 14. inner end cap, 15. pistons, 16. connectors, 17. travel(l)ing rests, 18. plastic cement caps, 19. symmetrical push arms.
The specific embodiment
In accompanying drawing 1 and accompanying drawing 2, elongated tubular profile sheet combined gas dispersal device is by many ribs tube wall support 4, annular filter disc 5, annular slide plate 6, ring slider 7, fixedly end cap 2, movable end cover 13, connector 16, piston 15, center push rod 9, multiedge cylinder 10, stainless steel spring 11, symmetrical push arm 19, travel(l)ing rest 17, plastic cement cap 18 and stainless steel band 8 are formed.Many ribs tube wall support 4 is processed by the plastic pipe that one section tube wall has protruding rib, and the pipe of this many ribs tube wall can pass through the machine-shaping of plastics expressing technique, cuts as required according to Len req.Pipe has stronger geometry intensity, adds the rib of several projectioies outside tube wall again, and intensity can further improve.The quantity of the outer rib of tube wall is controlled at the 3-68 root, rib is set with annular filter sheet 5, annular slide plate 6 and ring slider 7 outward, annular filter disc and annular slide plate alternately are stacked, be that a slice annular filter disc is with a slice annular slide plate, be carved with many tiny grooves on the end face of annular filter disc, when the end face of the end face of annular filter disc and annular slide plate is superimposed together, will form many circumferential tiny micropores.Because present embodiment is long tubular structure, annular filter disc and annular slide plate will be superimposed as very thick thickness, are difficult to equably they be spread out when needs are opened them, tend to occur that a place is opened and many places still are in closed state.When being folded into certain thickness, annular filter disc and annular slide plate install a ring slider 7 additional for this reason, ring slider and center push rod 9 link, therefore when the center push rod outwards promotes, ring slider outwards promotes together, will disperse annular filter disc and annular slide plate in many places like this, reach homodisperse effect.Because center push rod is also longer, for playing certain supporting role, has installed travel(l)ing rest 17 additional on center push rod, travel(l)ing rest is the cross shape, and four ends are circular-arc, can slide along the inwall of many ribs tube wall pipe.Groove between the two adjacent fins of many ribs tube wall support 4 can form the air flue of gas communication, can so that tube wall is inside and outside open-minded, form the many places gas passage according to the size perforate herein of tolerance simultaneously.One end of many ribs tube wall support 4 is connected with connector 16 by screw thread, the other end of connector installs and fixes end cap 2, fixedly the middle part of end cap has air inlet 1, and there is gas thread the air inlet inboard, can directly present embodiment be installed on the gas pipeline by this screw thread.Fixedly the side of end cap has high pressure admission mouth 2, and the piston bush at high pressure admission mouth and connector middle part connects, and a piston 15 is installed in the piston bush.Piston hinge is installed in an end of center push rod, and the other end of center push rod is connected with multiedge cylinder 10 by bolt, and the other end of multiedge cylinder is connected with movable end cover 13 by screw thread.Multiedge cylinder is with stainless steel spring 11 outward, and an end of stainless steel spring withstands inner end cap 14, and the other end withstands an end of multiedge cylinder.A positive stop lug boss 12 is arranged on the multiedge cylinder, and the distance between it and the inner end cap is spacing distance, can prevent that piston displacement is excessive.Symmetrical push arm 19 vertically has been installed on the center push rod, pack in the side opening of ring slider in the outer end of symmetry push arm, the aperture of side opening should can guarantee that so symmetrical push arm has a hysteresis gap when promoting ring slider greater than symmetrical push arm outer end diameter 0.5--35mm on the axial direction of many ribs tube wall support.This hysteresis space has guaranteed when piston promotes movable end cover by center push rod and multiedge cylinder, vertically arranged a plurality of symmetrical push arms are not to remove to promote ring slider simultaneously on the center push rod, but determine concrete hysteresis gap by the diverse location of outer end in the ring slider side opening of adjusting symmetrical push arm, form and outwards promote movable end cover earlier, outwards promote first group of ring slider after a while again near movable end cover, be the second group of ring slider that outwards promotes near movable end cover more after a while, by that analogy, also can realize reverse order, realize outwards promoting one by one the action of ring slider, reach the purpose of opening annular filter disc and annular slide plate equably.Plastic cement cap 18 is installed in the side opening outside, and the outside of plastic cement cap is fastening with a stainless steel band 8.
Present embodiment can directly be fixed on the gas pipeline by the gas thread of air inlet, compressed air enters many ribs tube wall support by the space in the connector, recess between two fins forms the good aeration passage, compressed air discharges through the micropore between countless annular filter discs and the annular slide plate, form countless microbubbles, this bubble quantity and bubble the more, bubble diameter is littler, and the transfer efficiency of oxygen in water is higher.Many ribs tube wall support that many ribs tube wall pipe is made has good structural strength, can make the longer tubular gas dispersion apparatus of length, and promptly can providing more, the inflation surface of large micropore area obtains better to inflate effect.When long-term work; outgassing micropore probably is compressed the living beings of airborne microparticle or growth and stops up; at this moment compressed air can not successfully be shed by branch; therefore air pressure constantly strengthens in the present embodiment; compressed air will outwards be pushed movable end cover open when reaching the certain pressure value; the closed assembly body of annular filter disc and annular slide plate has lost outside extruding force; under the percussion of Compressed Gas, be spread out; high speed airflow is being stirred current the groove on the annular filter disc end face is being carried out strong flushing, has reached the purpose of cleaning micropore.After Compressed Gas was unimpeded, the air pressure in the present embodiment descended thereupon, and movable end cover is inwardly motion under the effect of stainless steel spring, pushes annular filter disc and annular slide plate once more, recovers original duty, has realized the automatic cleaning function of present embodiment.When present embodiment has the part micropore blocked, when making gas dispersion not really desirable, can start artificial cleaning function, promptly by importing the gas of elevated pressures in the high pressure admission mouth in present embodiment, piston in the connector is pushed outwards to be gone out, outwards promote movable end cover by center push rod and multiedge cylinder, reach the cleaning purpose.When this elevated pressures gas disappeared, under the effect of stainless steel spring, movable end cover inwardly moved, and recovers original duty.In cleaning process, be vertically mounted on symmetrical push arm on the center push rod and can promote ring slider respectively the annular filter disc and the annular slide plate that are stacked are spread out equably, improve the effect of cleaning.
