Mit 5 ist ein Abblasen t ζ en ·$· bezeichnet, durch welchen der Luftüberschuß entweichen kann, während das Luft-Kunstharzpulver-Gemisch 28 durch die Leitung 4-austritt. Oberhalb des Kastens 1 ist unter Z.wischenfügung eines Absperrventils 6 eine mit einer Durch- \ gangsöffnung versehene Platte 9 angeordnet, auf welcher das zu-behandelnde Rohr-11 aufgesetzt ist. Sofern das Rohr einen Plansch 12 aufweist', wird dieser mittels Klemmen 10 auf der Platte 9 in senkrechter Lage festgeklemmt. Die Klemmverbindung zwischen dem unteren Ende des Rohres"11 und der Platte 9 kann jedoch auch-in anderer Weise ausgebildet sein.The device includes one containing the powdery synthetic resin Box 1, the. its bottom with an opening 2 .. ' for sucking air is provided, which is a porous or air-permeable Plate 24 flows through and swirls up the powdery synthetic resin mass, so that a box 1 is located Air-synthetic resin powder mixture 28 forms. A blow-off is denoted by 5, through which the excess air can escape, while the air-synthetic resin powder mixture 28 through line 4 exit. Above the box 1 is below Intermediate connection of a shut-off valve 6 one with a through \ The plate 9 provided with the passage opening is arranged on which the pipe 11 to be treated is placed. Unless the pipe has a Has puddle 12 ', this is clamped by means of clamps 10 on the plate 9 in a vertical position. The clamp connection between the lower end of the tube "11 and the plate 9 can however, it can also be designed in a different manner.
An dem oberen Flansch 13 des Rohres-ist mittels weiteren Klemmen lo.das Anschlußstück l4,15 einer Saugleitung 17 befestigt, welche zu einem Absperrventil 18 führt. An dieses On the upper flange 13 of the pipe is by means of further Clamps lo. The connection piece l4, 15 attached to a suction line 17 which leads to a shut-off valve 18. To this
Absperrventil ist unter Zwischenschaltung eines Schauglases 19 ein Staubfänger-Vakuumbehälter.20 angeschlossen. In diesem Behälter ist eine trichterförmige luftdurchlässige Membrane 21 eingebaut, welche über eine dichtende Verbindung 25 an . ■' einen--Rohrstutzen .26 angeschlossen ist. Der Rohrstutzen. 26 steht mit einem weiteren Absperrventil 22 in Verbindung,, an welches sich eine Ableitung 23 anschließt, durch die das überschüssige Kunstharzpulver abgeführt werden kann. In dem Be- ".-.·■ hälter 20 wird durch Vermittlung einer Rohrleitung 21 Unterdruck erzeugt.The shut-off valve is with the interposition of a sight glass 19 a dust collector vacuum container. 20 is connected. In this container is a funnel-shaped, air-permeable membrane 21 installed, which via a sealing connection 25 to. ■ ' a pipe socket .26 is connected. The pipe socket. 26 is connected to a further shut-off valve 22 which is followed by a discharge 23 through which the excess Resin powder can be discharged. In the loading ".-. · ■ container 20 is through the intermediary of a pipe 21 negative pressure generated.
Bei Bedarf kann zwischen der Platte 9 un<i dem Absperrventil 6 noch ein Zwischenorgan 7 eingebaut sein, das. gemäß Fig. 2 eine Anzahl von Schaufeln 8 aufweist, welche das Luft-Pulvergemisch in eine Wirbelbewegung versetzen. If necessary, an intermediate element 7 can be installed between the plate 9 and the shut-off valve 6, which, according to FIG. 2, has a number of blades 8 which set the air-powder mixture in a whirling motion.
Die beschriebene. Vorrichtung wird in. der Meise benutzt, .daß das vorgewärmte Rohr 11, welches mit Kunststoff ausgekleidet werden soll,., auf der Platte 9 festgeklemmt und die Saugleitung 17 an dem oberen Ende des Rohres mittels der.Klemmen 16 ange-.. schlossen ist. Es wird dann bei geschlossenen Ventilen 6,l8 und 22 in dem Behälter 20 ein Unterdruck erzeugt'. Dann wird, das Ventil l8 geöffnet, wobei der Unterdruck sich bis zu dem geschlossenen Ventil 6 fortpflanzt. Nun wird das Ventil l8 geschlossen und das Ventil- β geöffnet, so daß das zu behandelnde Rohr 11 sich mit Luft-Pulvergemisch vollsaugt. Dann wirdThe described. Device is used in. The tit, .that the preheated pipe 11, which is to be lined with plastic,., clamped on the plate 9 and the suction line 17 attached to the upper end of the tube by means of the clamps 16. is closed. A negative pressure is then generated in the container 20 with the valves 6, 18 and 22 closed. Then it will be, the valve 18 opened, the negative pressure propagating up to the closed valve 6. Now the valve is l8 closed and the valve β opened, so that the to be treated Tube 11 is soaked with air-powder mixture. Then it will be
Ventil β geschloseen und Ventil l8 geöffnet, so daß das überschüssige Pulver aus dem Rohr abgesaugt und in den Behälter abgeführt wird. Bei jeder solchen Operation wird stoßweise eine bestimmte Menge Kunstharzpulver in das Rohr 11 gezogen und auf seiner Innenwand aufgebracht, wo das Kunstharzpulver durch die Wärme verhärtet wird. Es hat sich gezeigt, daß durch den Überschuß an Kunstharzpulver., welcher während der thermischen Härtung auf der Innenwand des Rohres anwesend ist,, eine vollkommen porenfreie, gut haftende Auskleidungsschicht an der Innenwand des Rohres entsteht. In derselben Weise können auch Rohrkrümmer und Eckstücke ausgekleidet werden.Valve β closed and valve 18 opened so that the excess powder is sucked out of the tube and discharged into the container. In each such operation, a certain amount of synthetic resin powder is intermittently drawn into the tube 11 and applied to its inner wall , where the synthetic resin powder is hardened by the heat. It has been found that ,, is created by the excess resin powder. Which is present during the thermal curing on the inner wall of the tube a perfectly non-porous, well-adhering lining layer on the inner wall of the tube. Elbows and corner pieces can also be lined in the same way.
Wenn der Unterdruck in dem Behälter wieder hergestellt ist, kann die Operation wiederholt werden, wobei je nach der Anzahl der Stöße eine Auskleidungsschicht von gewürfehter Stärke erzielt werden kann.When the negative pressure is restored in the vessel, the operation can be repeated to provide a lining layer can be achieved by gewürfehter thickness depending on the number of collisions.
Das Kunstharzpulver kann eine Korngröße von 100 Ai haben , also diejenige Korngröße, mit welcher normalerweise das Kunstharzpulver von dem Hersteller geliefert wird.The synthetic resin powder can have a grain size of 100 Ai , that is to say the grain size with which the synthetic resin powder is normally supplied by the manufacturer.
Das Rohr 11 wird vor der Behandlung vorzugsweise auf eine Temperatur von 300 bis 350 C vorgewärmt.The tube 11 is preferably preheated to a temperature of 300 to 350 ° C. before the treatment.
