Definitions

  • the invention relates to a method and an apparatus for cleaning pneumatic delivery lines with a bypass pig according to the generic term of claim 1.
  • bypass pig is a subspecies of the displacement or Conveying pigs for pigging solids in pipelines.
  • a bypass pig is shown and described on page 164, in which as Propellant air is used which is tubular from behind Openings of the pig towards the front (in the direction of movement) is blown and through the nozzles arranged in the pig an air vortex on the The inner wall of the delivery line to be cleaned causes. In this airflow powders and granules are whirled in front of the pig.
  • bypass pig The disadvantage of the known bypass pig is, however, that only air vortices are generated by nozzle-like, forward-facing openings, which at appropriately loaded pneumatic conveying lines do not become one Carry out cleaning of the inner wall. In the worst case, this leads to the fact that the pig is protruding radially inwards into the delivery line Adhesion is fixed and can no longer be moved.
  • the newt described is not for cleaning pipelines with conveyance of granules in Flight promotion is suitable because its cleaning effect is insufficient and he is moving at an unsuitable speed.
  • the one used Compressed air is not suitable, as it is in the delivery line for delivery Take the intended granules with you.
  • the nozzles used for cleaning therefore ensure that the known one
  • the pig is only traversed with a relatively low air throughput, which is what granules brought in front of him do not make it fly.
  • Such a newt will So push the granulate to be conveyed in front of you and will soon be on wedge the corresponding pipe switches and flanges.
  • Brush pigs based on the bypass principle have also become known are suitable for cleaning pipes through which liquid flows.
  • Such Cleaning pigs have brush bodies on radially adjustable ones Sealing sleeves arranged.
  • the reason for the difficulty lies in the transfer of the excellent functioning pigging technology from the wet area with the for it necessary sealing sleeves in the pneumatic conveyor technology.
  • the invention is therefore based on the object, a method and one pig operated by the process, and a pig itself to further train that in pipelines carried by flight promotion Granules and dusts have a superior cleaning effect.
  • the object is by a method according to claims 1 and 11 and solved by a device according to claims 3 and 13.
  • C is the pig speed, while v is the gas speed Conveying air is.
  • a preferred embodiment of the pig provides that a number of interchangeable brush disks arranged on the pig axis predetermined different bristle hardness are provided and that at least these brush disks to a significant extent from the conveying air are enforced.
  • the invention provides a pig, which according to the prior art known bypass pigs resembles, but is different by the same Conveying air volume moves like the previous bulk transport, whereby its moving speed of a predetermined c / v proportion corresponds and the resulting combination of flow and mechanical cleaning influence on the bulk good Performs wall cleaning of the pipeline.
  • the invention is therefore not a displacement pig that cleans a "gun barrel” in the manner of a “cannon cleaner”, but a bypass pig that moves at a slow speed and through which the conveying gas flows at high speed, so that this conveying gas flows in the direction of flight the granulate is transported away from the pig and cannot be deposited.
  • the brushes with their individually attached and essentially radially designed bristles have the advantage that, with appropriate elastic bending, they also graze along the corresponding edges of pipe switches, welded seams and flange connections and there also remove the adhering granules and convey them away in front of them.
  • bristle-like functional features are used. For example lobe-like, trapezoidal, cylindrical or other shapes, in substantially radially outwardly directed bristles are used.
  • the pig axis in addition to several fixed brush disks rotatable brush disks are arranged.
  • These brush disks are equipped with guide vanes, and the air flow through these guide vanes leads to an active rotary drive of the respective Brush disc in the manner of a jet drive.
  • the types of brush disks mentioned at the beginning can be a single one Form bypass pig, or a bypass pig can only consist of one or several of the above combinations can be put together.
  • the pig axis is not necessarily rigid. It can also be articulated be trained.
  • the pig axis can thus also consist of several joints Pig axle sections exist, with some of the brush discs firmly on the axis is arranged, while again part of the brush discs is rotatably arranged on the pig axis and the rotation of the Brush discs through a turbine-like design with the help of the conveying air he follows.
  • the direction of rotation of the brush discs can vary depending on the type of installation Pig axis (orientation to the conveying air) must be the same or opposite.
  • a spherical brush pig provided that also works with an air flow so that the already o. a. Correlations come into play accordingly.
  • the essential The difference to the form described so far is that the Air flow not directly through the body of the brush pig itself passes through, but between the inner wall of the delivery line and the Surface of the spherical brush pig, from which the individual Bristles protrude, as well as between the individual bristles themselves preferred application of the spherical brush pig is included Delivery pipes with relatively small diameters, for example 3D, 5D and the like.
  • FIGS. 1 and 2 show a first embodiment of a brush pig 1 shown, which consists of a fixed axis 8 on which a number of fixed brush discs 4,5,6,7 lying one behind the other and parallel are threaded to each other.
  • the axis 8 is at the rear end by a closure piece 9 closed, which essentially consists of two split washers 13th exists, which are held together by a clamping ring 12.
  • the closure piece 9 is very much due to the clamping ring 12 used easy to open and close.
  • the axis 8 consists of a There is a threaded bolt which is connected at the front to the tip 11 and which its rear side instead of the closure piece 9 a corresponding Threaded nut, which also carries the brush disks 4-7 and holds the associated spacers 10 together.
  • each individual brush disk 4 it is of course also possible to pass through each individual brush disk 4 to fix a corresponding clamping device on an axis.
  • the rear closure piece 9 can also be used as a clamping device be trained.
  • each brush disk 4 according to Figure 3 from one Brush ring 18 is made with any number of radial outside bristles is occupied.
  • the bristles are held in a holding disc 19, which in turn is part of a Carrier disc 20 is, which is threaded on the axis 8.
  • the newt therefore does not run the risk of stowing the granulate in front of it; on This prevents jamming in a granulate piled up in front of it.
  • FIG. 2 The perspective view of a brush pig 1 with fixed Brush disks 4-7 are shown in Figure 2. It can be seen here that the Bypass air flow flows out of the bypass bores 15 16 and through the individual brush wreaths 18 goes through.
  • direct air flow 17 is also shown, which is also the individual Brush wreaths 18 interspersed.
  • the invention also sees in an embodiment not shown for example that some of the brush disks, e.g. B. the brush discs 5, 6, are arranged passively rotatable. This would be the respective brush wreath 18 have a helical contour and each of the brush disks 5, 6 passively twists in the manner with the longitudinal movement of the brush pig 1 a swirl movement in the pipeline.
  • the two brush disks 5, 6 come together turn in opposite directions if a corresponding opposite Helical toothing in the outer area of the respective brush ring 18 is provided.
  • one Brush disc with its orientation towards the front and the same trained Brush disk 6 is installed with its orientation to the rear, so one generate opposing swirl movement.
  • Figure 4 shows as a further embodiment that it is also active rotationally driven brush disks 22, 23 on a brush pig 21 there.
  • the middle brush disks 22, 23 turbine-like rotary drive.
  • Each is a front, fixed Brush disk 24 (see Figure 5) and a rear fixed brush disk 7 provided between which the rotating brush discs 22, 23rd are arranged.
  • the front fixed brush disk 24 according to FIG Circumferentially distributed recesses 25 through which the direct air flows in the direction of arrow 3.
  • the brush ring 19 is through corresponding spokes 26 supported against the axis 8.
  • the Recesses 25 are intended to cause that of the nozzle-like Guide vanes 27 of the rotating driven brush disks 22, 23 flowing out Air in a large cross section can penetrate the front brush disk 24.
  • Each rotary brush disk 22, 23 is approximately according to FIG. 6 educated. There are radially inward the washer 19 obliquely staggered vanes 27, each forming a nozzle vane.
  • each individual brush disc 22, 23 takes place here via needle bearing 28.
  • the needle bearing consists of a fixed inner ring 29, the needles for storage and a rotating outer ring 30.
  • the turbine ring 31, which adjoins the needle bearing radially outwards includes the aforementioned vanes 27.
  • FIG. 7 shows a spherical embodiment of a brush pig 34 out. This embodiment effects a completely free movement the pipe system of the delivery lines 2.
  • Bypass bores for the air flow through the brush pig 34 are not provided here because the conveying air between the inner wall of the delivery line and the surface of the spherical brush pig 34, from which the individual bristles 36 protrude, as well as between the individual bristles 36 themselves through strikes.
  • the bristles 36 are in turn elastic, so that they are in the manner already described the inner wall of the conveyor line 2 clean. In the division and training, the bristles 36 are designed that sufficient air 38 can flow through between them, and on the other hand, a sufficient cleaning effect is achieved. To do this Clearances 35 are formed between the bristles 36 through which the air 38 flow along the individual paths 37 and the cleaned particles can carry with him.
  • a major advantage of this embodiment is that the spherical brush pig 34 always in bends and knee areas optimally touches the inner wall of the delivery lines 2 and thus also reliably cleans. This is particularly so because it is free in every direction is movable in the conveyor lines 2, making it particularly small Pipe diameters can be used in which others Embodiments already tend to jam or stick.
  • the bristles 36 themselves can be designed as individual bristles or also as bristle groups.
