It comprises a rotating central shaft 5, actuated by a motor, at least one rotating planet shaft (7), its axis being parallel to that of the central shaft, fitted with a brush whose bristles (11) are long enough to enter into frictional contact with the outer surface of the pipes, and a planetary reduction gear (2) which drives the planet shaft off the central shaft. Application to cleaning heat exchangers.

Description

Appareil de nettoyage des surfaces externe, et éventuellement interne, de tubes de faible diamètre.Apparatus for cleaning the external, and possibly internal, surfaces of small diameter tubes.

La présente invention concerne un appareil de nettoyage de dépôts sur la surface externe de tubes de faible diamètre, en particulier de tubes faisant partie d'un faisceau tubulaire d'échange de chaleur. The present invention relates to an apparatus for cleaning deposits on the external surface of small diameter tubes, in particular tubes forming part of a heat exchange tube bundle.

On a déjà proposé de nettoyer la surface interne de tubes de faible diamètre par une brosse rotative, et leur surface externe à l'aide d'une bande abrasive entraînée en déplacement par des arbres rotatifs disposés autour du tube et comportant un renvoi amenant la bande à venir frotter contre la surface externe du tube. It has already been proposed to clean the internal surface of small diameter tubes by a rotary brush, and their external surface using an abrasive band driven in displacement by rotary shafts arranged around the tube and comprising a return bringing the band rub against the outer surface of the tube.

Ceci nécessitait deux opérations successives. Par ailleurs, le nettoyage de la surface externe n'était satisfaisant que si la lame de toile émeri restait suffisamment tendue, ce qui nécessitait des réajustages fréquents de sa tension.This required two successive operations. Furthermore, the cleaning of the external surface was satisfactory only if the emery cloth blade remained sufficiently taut, which required frequent readjustments of its tension.

La présente invention a pour but de procurer un appareil de nettoyage de dépôts tels que du tartre sur des surfaces externe, et éventuellement interne, de tubes, qui ne nécessite qu'un temps très court par tube, compte tenu du grand nombre de tubes dans des faisceaux tubulaires d'échangeurs de chaleur, et élimine néanmoins complètement ces dépôts. The object of the present invention is to provide an apparatus for cleaning deposits such as tartar on the external, and possibly internal, surfaces of tubes, which requires only a very short time per tube, given the large number of tubes in bundles of heat exchangers, and nevertheless completely eliminates these deposits.

L'appareil selon l'invention est caractérisé en ce qu'il comprend un arbre central rotatif mu par un moteur, au moins un arbre satellite rotatif d'axe parallèle à celui de l'arbre central, muni d'une brosse à poils de longueur suffisante pour entrer en contact frottant avec la surface externe des tubes, et un réducteur planétaire à couronne d'entraînement de l'arbre satellite par l'arbre central. The apparatus according to the invention is characterized in that it comprises a rotary central shaft driven by a motor, at least one rotary satellite shaft with an axis parallel to that of the central shaft, provided with a bristle brush. sufficient length to come into frictional contact with the external surface of the tubes, and a planetary reduction gear with a drive crown of the satellite shaft through the central shaft.

Il comprend de préférence au moins trois arbres satellites rotatifs régulièrement espacés autour de l'axe de l'arbre central, tournant sur la couronne du réducteur. It preferably comprises at least three rotary satellite shafts regularly spaced around the axis of the central shaft, rotating on the crown of the reduction gear.

Il peut être adapté pour assurer aussi le nettoyage de la surface interne des tubes ; son arbre central est alors de diamètre inférieur au diamètre interne des tubes, et muni sur sa surface d'une brosse à poils de longueur suffisante pour entrer en contact avec la surface interne des tubes. It can be adapted to also clean the internal surface of the tubes; its central shaft is then of diameter less than the internal diameter of the tubes, and provided on its surface with a bristle brush of sufficient length to come into contact with the internal surface of the tubes.

I1 est décrit ci-après, à titre d'exemple et en référence aux figures schématiques du dessin annexé, un appareil de nettoyage des surfaces interne et externe de tubes d'un échangeur de chaleur. I1 is described below, by way of example and with reference to the schematic figures of the accompanying drawing, an apparatus for cleaning the internal and external surfaces of tubes of a heat exchanger.

La figure 1 représente en élévation l'appareil muni de son arbre central, d'un arbre satellite et de la colonnette de maintien de la couronne porte contre-pointe. FIG. 1 shows in elevation the apparatus provided with its central shaft, a satellite shaft and the baluster for holding the crown for the tailstock.

La figure 2 représente en section droite dans la zone du réducteur planétaire l'entraînement de trois arbres satellites par l'arbre central. Figure 2 shows in cross section in the area of the planetary gearbox the drive of three satellite shafts by the central shaft.

La figure 3 représente en section droite dans la zone des brosses la disposition des 3 colonnettes qui maintiennent la couronne porte contre-pointe. Figure 3 shows in cross section in the brush area the arrangement of the 3 columns which hold the crown door tailstock.

Dans la figure 1, il part du réducteur planétaire 2 un arbre central 3, entraîné en rotation par un moteur, non représenté, et un arbre satellite 7. Cet arbre central muni d'un pignon d'engrenage 13, entraîne par le mandrin 4 la brosse centrale 5 munie de poils de nettoyage 6 venant frotter sur la surface interne du tube 1, telle qu'une brosse dite "flex-hone", dont les poils comportent à leur extrémité une boule d'abrasif. L'arbre satellite 7, muni d'un pignon 14 en prise avec le pignon 13 de l'arbre central, est entraîné en rotation autour de son axe et roule autour de l'arbre central sur le pourtour interne 17 du réducteur 2. Il entraîne par le mandrin 8 la brosse périphérique d'axe 9 à poils de nettoyage 11 venant frotter sur la surface externe du tube 1.L'extrémité de l'axe 9 de la brosse est maintenu dans la contre-pointe 10, solidaire d'une couronne porte contre-pointe, non représentée, maintenue par des colonnettes telles que 12. In FIG. 1, it starts from the planetary reduction gear 2 a central shaft 3, driven in rotation by a motor, not shown, and a satellite shaft 7. This central shaft provided with a gear pinion 13, drives by the mandrel 4 the central brush 5 provided with cleaning bristles 6 rubbing against the internal surface of the tube 1, such as a so-called "flex-hone" brush, the bristles of which have at their end a ball of abrasive. The satellite shaft 7, provided with a pinion 14 in engagement with the pinion 13 of the central shaft, is driven in rotation about its axis and rolls around the central shaft on the internal periphery 17 of the reduction gear 2. It driven by the mandrel 8 the peripheral brush of axis 9 with cleaning bristles 11 rubbing against the external surface of the tube 1. The end of the axis 9 of the brush is held in the tailstock 10, integral with a tailstock crown, not shown, held by columns such as 12.

Dans la figure 2, le pignon central d'engrenage 13 correspondant à l'arbre central 3 entraîne les pignons 14, 15,16, correspondant à trois arbres satellites (7A, 7B, 7C), tels que l'arbre 7 de la figure 1, à l'intérieur du réducteur 2. Ces pignons tournent donc chacun autour de son axe et autour du pignon central 13, comme représenté par les flèches, en roulant sur le pourtour interne 17 du boîtier 2. In FIG. 2, the central gear pinion 13 corresponding to the central shaft 3 drives the pinions 14, 15, 16, corresponding to three satellite shafts (7A, 7B, 7C), such as the shaft 7 of the figure 1, inside the reduction gear 2. These pinions therefore each rotate around its axis and around the central pinion 13, as shown by the arrows, while rolling on the internal periphery 17 of the housing 2.

Dans la figure 3, la brosse centrale 5 nettoie la surface interne du tube 1. Les brosses périphériques 9A, 9B, 9C munies de poils llA, llB, llC tournent chacune autour de son axe, et tournent ensemble avec les colonnettes 12, 18, 19 autour du tube, comme représenté par les flèches.  In FIG. 3, the central brush 5 cleans the internal surface of the tube 1. The peripheral brushes 9A, 9B, 9C provided with bristles llA, llB, llC each rotate around its axis, and rotate together with the balusters 12, 18, 19 around the tube, as shown by the arrows.
