Description
Die Erfindung betrifft einen kompressibel verformbaren Rohrmolch zur Reinigung von Rohrleitungen, insbesondere von pneumatischen Förderanlagen, der einen kompressibel verformbaren Grundkörper aufweist.The invention relates to a compressible malleable pig for cleaning of pipelines, especially of pneumatic conveying systems, the one has compressible deformable base body.
Es ist bekannt, Rohrleitungen für die Förderung pastöser oder flüssiger Produkte mit Hilfe sogenannter Rohrmolche bei Beendigung des Fördervorgangs von anhaftenden Produktrückständen zu befreien. Der als Kugel oder Ellipsoid ausgeformte Rohrmolch wird in die Förderleitung eingeführt und mit Hilfe einer Förderflüssigkeit hydraulisch durch die Leitung getrieben.It is known to have pipelines for conveying pasty or liquid products with the help of so-called pipe pigs when the conveying process of to remove adhering product residues. The one as a sphere or an ellipsoid shaped pig is introduced into the delivery line and with the help of a Pumped liquid hydraulically driven through the line.
Üblicherweise weisen derartige Rohrmolche ein hohes Gewicht und eine geringe Kompressibilität auf. Es ist daher in der Regel nicht möglich, sie unter der Wirkung eines Druckgases durch die Förderleitung zu bewegen, da dieses den Rohrmolch am Ende der Förderleitung geschoßartig beschleunigen würde. Wegen der großen Masse des Molches muß eine Beschädigung des Empfangsbehälters oder eine Gefährdung des Personals durch den Einsatz spezieller Fangvorrichtungen vermieden werden. Pneumatische Förderanlagen, in denen keine Einrichtungen zum Pumpen von Flüssigkeiten vorhanden sind, werden aus diesem Grund nicht mit Rohrmolchen gereinigt.Tubular pigs of this type usually have a high weight and a low weight Compressibility. It is therefore usually not possible to take them under the effect a compressed gas to move through the delivery line, as this the pig would accelerate like a bullet at the end of the delivery line. Because of the large mass of the newt must damage the receiving container or a risk to personnel through the use of special safety devices be avoided. Pneumatic conveyors where no facilities are available for pumping liquids for this reason cleaned with newt.
Es sind ferner Rohrmolche erhältlich, die aus einem geschäumten Kautschuk bestehen und daher ein geringeres Gewicht aufweisen. Da sie bei einer pneuma tischen Förderung wegen des fehlenden Flüssigkeitsfilm auf der Wandung einen erheblichen Reibungswiderstand ausüben, der zu einem Festsetzen des Molches in der Rohrleitung oder auch zu seiner eigenen Zerstörung führen kann, sind auch diese nur bei hydraulischen Systemen einsetzbar.Tubular pigs are also available, which are made of a foamed rubber exist and therefore have a lower weight. Since they are with a pneuma table promotion due to the lack of liquid film on the wall exert considerable frictional resistance, which will cause the pig to stick in the pipeline or can also lead to its own destruction these can only be used with hydraulic systems.
In der Druckschrift DE 195 13 104 A1 wird ein Rohrmolch mit axialsymmetrischer Form offenbart, der einen Grundkörper aus gummielastischem Material aufweist. Zur Verringerung der Reibung zwischen Rohrmolch und Wandung der zu reinigen den Rohrleitung ist der Grundkörper mit einer Beschichtung aus einem Fluorpoly mer versehen, welche die elastischen Eigenschaften des Rohrmolchs nicht verschlechtert. Eine derartige Beschichtung ist jedoch nur mit einem erheblichen Fertigungsaufwand auf dem Grundkörper aufbringbar und kann nachträglich nicht mehr gewechselt werden.In the publication DE 195 13 104 A1 a pig with an axially symmetrical Form disclosed, which has a base body made of rubber-elastic material. To reduce the friction between the newt and wall of the clean The pipeline is the basic body with a coating made of a fluoropoly mer provided, which the elastic properties of the newt not worsened. However, such a coating is only significant Manufacturing expenditure can be applied to the base body and cannot subsequently to be changed more.
Ein vergleichbarer Rohrmolch ist aus dem Gebrauchsmuster DE-GM 19 62 742 bekannt, bei dem ein Kern aus geschäumtem Gummi zur Erhöhung der Lebensdauer mit einem hochabriebfesten Überzug aus einem Kunststoff, beispielsweise geschäumtem Polyurethan versehen wird.A comparable pipe pig is from the utility model DE-GM 19 62 742 known in which a core made of foamed rubber to increase the Service life with a highly abrasion-resistant plastic cover, for example, foamed polyurethane is provided.
In der Patentschrift US 3,011,197 wird ebenfalls vorgeschlagen, einen Rohrmolch mit einer äußeren Beschichtung aus flexiblem Polyurethan zu versehen, wobei der geschäumte Grundkörper einen mit einem Druckgas befüllbaren Hohlraum aufweisen kann.US Pat. No. 3,011,197 also proposes a pig to be provided with an outer coating of flexible polyurethane, the foamed base body a cavity that can be filled with a compressed gas can have.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die aus dem Stand der Technik bekannten Rohrmolche in der Weise weiterzuentwickeln, daß sie auch unter der Wirkung eines Druckgases zuverlässig durch eine Rohrleitung bewegbar sind. The present invention is based on the object of the prior art Technology known to develop newt pipes in such a way that they too reliably movable through a pipeline under the action of a compressed gas are.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Oberfläche des Rohr molchs mit einer textilen Umhüllung versehen ist.The object is achieved in that the surface of the tube Molchs is provided with a textile covering.
Die textile Umhüllung setzt zum einen die Reibung des Molchs bei der pneuma tischen Förderung herab und schützt ihn darüber hinaus vor Beschädigungen. Durch die Kompressibilität kann der Rohrmolch darüber hinaus auch Rohrleitun gen reinigen, die einen in Form oder Fläche veränderlichen Querschnitt aufwei sen. Die Strömungskanäle von Verteilorganen und Umlenkstücken der Förder anlage können rohrknieartig ausgebildet werden, ohne daß ein Festsetzen des Rohrmolchs oder das Auftreten hoher dynamischer Kräfte bei seiner Umlenkung zu befürchten ist. Besondere Anforderungen an die Molchfähigkeit des Leitungs systems werden nicht gestellt.On the one hand, the textile covering sets the friction of the pig at pneuma table promotion and also protects it from damage. Due to the compressibility, the newt can also be piped Clean any areas that have a cross-section that changes in shape or area sen. The flow channels of distribution elements and deflection pieces of the conveyor System can be designed like a pipe knee without fixing the Rohrmolch or the occurrence of high dynamic forces during its deflection is to be feared. Special requirements for the piggability of the line systems are not provided.
Geeignete Werkstoffe für die textile Umhüllung sind beispielsweise dicht gewobe ne Baumwollstoffe oder Fließe aus Mikrofasern, insbesondere aus Polyester- oder Polypropylenfasern.Suitable materials for textile wrapping are, for example, tightly woven ne cotton fabrics or tiles made of microfibers, especially polyester or Polypropylene fibers.
Nach einer besonderen Ausführung der Erfindung ist die textile Umhüllung elektrisch leitfähig ausgeführt. Bei der Reinigung von Förderleitungen, aus denen zündfähige Stäube wie Schwefel- oder Zuckerstaub zu entfernen sind, kann auf diese Weise eine Funkenbildung infolge elektrostatischer Aufladungen verhindert werden. Eine dauerhafte Leitfähigkeit der Umhüllung wird vorzugsweise durch Einarbeiten metallischer Fasern in das Textilgewebe herbeigeführt.According to a special embodiment of the invention, the textile covering electrically conductive. When cleaning delivery lines from which ignitable dusts such as sulfur or sugar dust can be removed this prevents sparking due to electrostatic charges become. A permanent conductivity of the sheath is preferably by Incorporation of metallic fibers into the textile fabric.
Um die Umhüllung ihrerseits gut reinigen zu können, wird die Umhüllung nach einer weiteren Ausführung der Erfindung vom Grundkörper abnehmbar ausge führt. In order to be able to clean the casing well, the casing is subsequently a further embodiment of the invention detachable from the base body leads.
Der kompressible Grundkörper kann beispielsweise aus einem zellulären Werk stoff wie Zellgummi bestehen oder als elastisch verformbarer Hohlkörper ausge führt werden. Geometrie und Werkstoff des Grundkörpers sind auf die vom Rohr molch auszugleichenden Querschnittsänderungen der Förderleitung sowie den zur Verfügung stehenden pneumatischen Förderdruck abzustimmen.The compressible base body can be, for example, from a cellular plant Made of material such as cellular rubber or as an elastically deformable hollow body leads. The geometry and material of the base body are based on that of the pipe cross-sectional changes to be compensated for in the delivery line and the available pneumatic delivery pressure.
Aus den zuvor genannten Gründen wird auch der Grundkörper bevorzugt elek trisch leitfähig ausgeführt. Dies kann zum Beispiels durch Zugabe von speziellem Ruß in den Werkstoff des Grundkörpers bewirkt werden.For the reasons mentioned above, the base body is also preferably electrical trically conductive. This can be done, for example, by adding special Soot can be caused in the material of the base body.
Die Figuren stellen beispielhaft und schematisch verschiedene Ausführung der Erfindung dar.The figures represent, by way of example and schematically, different versions of the Invention.

Der in Fig. 1 dargestellte Rohrmolch 1 umfaßt einen Grundkörper 2, der als Hohl kugel aus einem kompakten, elastisch verformbaren Werkstoff ausgeführt ist. Der Hohlraum 3 ist mit einem Gas gefüllt, das gegenüber der Umgebung einen Über druck aufweisen kann.The pig 1 shown in Fig. 1 comprises a base body 2, which is designed as a hollow sphere of a compact, elastically deformable material. The cavity 3 is filled with a gas which may have an excess pressure from the environment.
Der Grundkörper 2 ist von einer textilen Umhüllung 4 umgeben, die im Ausfüh rungsbeispiel nicht stoffschlüssig mit dem Grundkörper 2 verbunden und daher zu Reinigungszwecken abnehmbar. Wie aus Fig. 2 zu ersehen, weist die textile Umhüllung einen Schlitz 5 auf, durch den der Grundkörper 2 in die textile Umhül lung 4 eingefügt wird. Der Schlitz 5 wird nachfolgend durch einen Klettverschluß 6 verschlossen.The base body 2 is surrounded by a textile covering 4 , which is not cohesively connected to the base body 2 in the exemplary embodiment and can therefore be removed for cleaning purposes. As can be seen from FIG. 2, the textile covering has a slot 5 through which the base body 2 is inserted into the textile covering 4 . The slot 5 is subsequently closed by a Velcro 6 .
Um die textile Umhüllung 4 elektrisch leitfähig auszurüsten, sind metallische Fasern 7 in das Gewebe der textilen Umhüllung 4 eingearbeitet.In order to make the textile covering 4 electrically conductive, metallic fibers 7 are incorporated into the fabric of the textile covering 4 .
Im Ausführungsbeispiel nach Fig. 3 ist der Grundkörper 2 als Ellipsoid aus einem zellulärem Werkstoff gestaltet, der ebenfalls von einer textilen Umhüllung 4 umgeben ist.In the exemplary embodiment according to FIG. 3, the base body 2 is designed as an ellipsoid made of a cellular material, which is also surrounded by a textile covering 4 .
Fig. 4 zeigt die Reinigung einer Anlage zur pneumatischen Förderung von Schütt gut unter Zuhilfenahme eines erfindungsgemäßen Rohrmolchs. Die Förderanlage umfaßt einen Schüttgutsilo 8, aus dem mittels einer Zellenradschleuse 9 Schütt gut in eine Förderleitung 10 eingespeist werden kann, das nachfolgend durch von einem Gebläse (bzw. einen Verdichter) 11 bereitgestelltes Druckgas zu Empfangsbehältern 12 gefördert wird. Fig. 4 shows the cleaning of a system for the pneumatic conveyance of bulk well with the help of a pipe pig according to the invention. The conveyor system comprises a Schüttgutsilo 8, 9 bulk can be easily fed in a feed line 10 from the means of a rotary valve, which is supported by below by a blower (or a compressor) 11-supplied pressurized gas to receiving containers 12th
Der Strömungskanal der Förderleitung 10 setzt sich zusammen aus geraden Leitungsabschnitten 13, die horizontal oder vertikal verlaufen, aus kreisbogen förmigen Rohrbögen 14, einem Verteilorganen 15, in denen der Strömungskanal knickförmig abzweigen kann sowie aus Umlenkstücken 16 mit polygoner Umlenkung des Förderstroms. Die geraden Leitungsabschnitte 13 weisen eine Vielzahl von Verengungen 17 auf, mittels derer die Verteilung des Schüttguts im Förderstrom gezielt beeinflußt werden kann.The flow channel of the delivery line 10 is composed of straight line sections 13 , which run horizontally or vertically, of circular-shaped pipe bends 14 , a distribution element 15 , in which the flow channel can branch off in an elbow shape, and of deflection pieces 16 with polygonal deflection of the delivery flow. The straight line sections 13 have a large number of constrictions 17 , by means of which the distribution of the bulk material in the flow can be influenced in a targeted manner.
Über eine verschließbare Aufgabestation 18 in der Gebläse 11 und Förderleitung 13 verbindenden Reinluftleitung 19 wird der Rohrmolch 1 in den zu reinigenden Strömungskanal eingeführt und unter der Wirkung des Druckgases zu den Empfangsbehälters 12 gefördert. Durch seine erfindungsgemäße Ausgestaltung kann der Rohrmolch 1 sowohl die Verengungen 17 in den geraden Abschnitten als auch die knickartige Umlenkung im Verteilorgan überwinden. Im Umlenkstück 16, in dem sich der Strömungskanal vorübergehend erweitert, liegt der Rohrmolch 1 ausreichend dicht an der Wandung des Strömungskanals an, um ein Festsetzen zu verhindern und eine ausreichende Reinigungswirkung zu gewährleisten. The pipe pig 1 is introduced into the flow channel to be cleaned and is conveyed to the receiving container 12 under the action of the compressed gas via a closable feed station 18 in the clean air line 19 connecting the blower 11 and the delivery line 13 . Due to its design according to the invention, the newt 1 can overcome both the constrictions 17 in the straight sections and the kink-like deflection in the distribution member. In the deflection piece 16 , in which the flow channel temporarily widens, the pipe pig 1 lies sufficiently close to the wall of the flow channel in order to prevent it from sticking and to ensure a sufficient cleaning effect.
