Description

La présente invention concerne un appareil d'extraction et d'alimentation de matières boueuses à une station de traitement de celles-ci. Plus particulièrement, elle fournit un appareil conçu pour permettre l'extraction et le malaxage de toutes matières boueuses, à partir de bassins ou fondrières profondes à rives en forte déclivité, ainsi que leur alimentation, sous forme relativement homogène, à une station de traitement située à distance, par l'intermédiaire d'une pompe de propulsion sous pression faisant partie intégrante de l'appareil.The present invention relates to an apparatus for extracting and supplying muddy materials to a treatment station thereof. More particularly, it provides a device designed to allow the extraction and mixing of all muddy materials, from deep basins or potholes with steep slopes, as well as their feeding, in relatively homogeneous form, to a treatment station located remotely, via a pressurized propulsion pump which is an integral part of the device.

Dans la technique actuelle, on connaît de nombreux appareils d' extraction de boues parmi lesquels on peut citer, entre autres, les excavatrices, pelleteuses, dragues et racleurs. L'utilisation de ces appareils est essentiellement conditionnée par la consistance des matières boueuses dans le bassin d'extraction, qui se présentent, dans certains cas, plus ou moins sèches et craquelées dans les couches superficielles et de plus en plus molles et humides en profondeur. Lors de ces conditions, il devient très risqué de faire pénétrer ces appareils connus sur le lieu d'extraction, du fait des possibilités d'enlisement et même d'effondrements imprévisibles du terrain sous l'appareil. En conséquence, l'appareil, objet de l'invention, a été conçu pour permettre l'extraction en place de matières boueuses, notamment dans les conditions précitées, et leur transfert sous forme homogène par propulsion sous pression, du lieu d'extraction à une station de traitement située à distance sur terrain ferme.In the current technique, numerous sludge extraction devices are known, among which mention may be made, among others, of excavators, excavators, dredgers and scrapers. The use of these devices is essentially conditioned by the consistency of muddy materials in the extraction basin, which appear, in some cases, more or less dry and cracked in the surface layers and increasingly soft and moist at depth. . Under these conditions, it becomes very risky to penetrate these known devices on the place of extraction, because of the possibilities of getting bogged down and even unpredictable collapses of the ground under the device. Consequently, the apparatus, object of the invention, was designed to allow the extraction in place of muddy materials, in particular under the aforementioned conditions, and their transfer in homogeneous form by propulsion under pressure, from the place of extraction to a treatment station located remotely on firm ground.

Selon l'invention, un tel appareil, comportant une pompe, du type pompe à béton, adaptée pour propulser les matières extraites vers la station de traitement de celles-ci, est remarquable du fait qu'il comprend, d'aval en amont, au moins une vis hélicoïdale fouilleuse et d'extraction, montée par son extrémité arrière sur une trémie de réception des matières extraites, de manière à pouvoir être, à la demande, pivotée latéralement dans les deux sens et relevée ou abaissée dans un plan vertical, cette trémie de réception étant reliée, de manière réglable, à l'assise de base de la pompe et supportant, de manière articulée, la partie d'extrémité basse d'un dispositif élévateur et de reprise des matières extraites qu'elle contient, ce dispositif élévateur étant monté de manière articulée, par sa partie d'extrémité haute, sur un support du bâti de la pompe, afin qu' il déverse lesdites matières dans la trémie d'alimentation de celle-ci.According to the invention, such an apparatus, comprising a pump, of the concrete pump type, adapted to propel the extracted materials towards the treatment station thereof, is remarkable in that it comprises, from downstream to upstream, at least one excavating and extraction helical screw, mounted by its rear end on a hopper for receiving the extracted materials, so that it can be pivoted laterally in both directions and raised or lowered in a vertical plane, on request, this receiving hopper being connected, in an adjustable manner, to the base of the pump and supporting, in an articulated manner, the lower end part of a lifting and recovery device for the extracted materials which it contains, this lifting device being articulated, by its upper end part, on a support of the pump frame, so that it pours the said materials into the feed hopper thereof.

De manière plus spécifique et conformément à l'invention, afin que l'appareil puisse assurer une extraction à débit plus important et suivant une bande plus conséquente qu'il n'est possible avec une seule vis, il est pourvu de deux vis, montées respectivement latéralement à ladite trémie de réception, afin de pouvoir balayer chacune un angle d'approximativement 90° par rapport à l'axe longitudinal de cette trémie. A noter que cette trémie est adaptée pour être montée sur une assise de base formant traîneau, mais susceptible d'être pourvue de chenilles. En outre, cette trémie de réception, constituant en même temps une trémie de reprise des matières extraites par le dispositif élévateur, est adaptée à sa partie avant pour supporter, de manière articulée, un dispositif d'extraction du type à double vis transversale avant, à pas contraires, et élévateur à godets ou raclettes, ce dispositif d'extraction ayant une largeur sensiblement égale à celle de la trémie et pouvant fonctionner seul ou de conserve avec les deux vis latérales d'extraction.More specifically and in accordance with the invention, so that the apparatus can ensure extraction at a higher flow rate and along a larger strip than is possible with a single screw, it is provided with two screws, mounted respectively laterally to said receiving hopper, in order to be able to sweep each an angle of approximately 90 ° relative to the longitudinal axis of this hopper. Note that this hopper is adapted to be mounted on a base seat forming a sled, but may be provided with tracks. In addition, this receiving hopper, constituting at the same time a hopper for taking up the materials extracted by the lifting device, is adapted to its front part to support, in an articulated manner, an extraction device of the double transverse front screw type, with opposite steps, and bucket elevator or squeegee, this extraction device having a width substantially equal to that of the hopper and being able to operate alone or in a can with the two lateral extraction screws.

Par ailleurs, selon l'invention, chaque vis d'extraction utilisée dans cet appareil est pourvue à son extrémité avant d'une ogive rotative de protection et comporte, à cette extrémité, une partie nue pouvant atteindre moitié de sa longueur totale, alors que son autre moitié arrière est enfermée dans une gaine tubulaire, pourvue inférieurement d'un volet réglable adapté par son bord inférieur pour constituer un patin d'assise de la vis en même temps qu'un moyen de raclage et de nivellement de l'emplacement d'extraction, les matières raclées et ramenées dans l'axe de l'appareil étant reprises par le dispositif d'extraction de l'avant de la trémie.Furthermore, according to the invention, each extraction screw used in this device is provided at its front end with a rotary protective warhead and comprises, at this end, a bare part which can reach half of its total length, while its other rear half is enclosed in a tubular sheath, provided below with an adjustable flap adapted by its lower edge to constitute a pad for the seat of the screw at the same time as a means of scraping and leveling the location d 'extraction, the scraped material and returned to the axis of the device being taken up by the extraction device from the front of the hopper.

D'autre part, comme cette trémie de réception, l'assise de base de la pompe est constituée sous forme d'un traîneau ou barge, susceptible d'être pourvu de chenilles, cette assise supportant de manière articulée, à son extrémité arrière, l'extrémité correspondante du châssis de support de la pompe et, à son extrémité avant, également de manière articulée, un portique de levage de l'extrémité côté trémie d'alimentation de la pompe, ce portique étant conçu pour permettre la mise en position horizontale de cette dernière, alors que son assise de base est sur une pente descendante de la rive du lieu d'extraction, cette assise étant retenue en glissement par un ensemble d'amarrage, ancré sur la terre ferme et comportant un palan à câbles ou à chaînes, avec treuil de commande situé sur le châssis de la pompe. A noter que le portique de mise en position horizontale de la pompe est conçu d'une hauteur suffisante pour que l'assise de base puisse prendre appui sur des rives de terrain ferme pouvant avoir une très forte déclivité supérieure à la pente de talus naturel et pouvant avoisiner une pente à 80 % sinus.On the other hand, like this receiving hopper, the base seat of the pump is constituted in the form of a sled or barge, capable of being provided with tracks, this seat supporting in an articulated manner, at its rear end, the corresponding end of the pump support frame and, at its front end, also in an articulated manner, a gantry for lifting the end on the feed hopper side of the pump, this gantry being designed to allow positioning horizontal of the latter, while its base is on a slope descending from the bank of the place of extraction, this base being held in sliding by a mooring assembly, anchored on dry land and comprising a cable hoist or at chains, with control winch located on the pump frame. Note that the gantry for horizontal positioning of the pump is designed with a height sufficient for the base to be able to rest on banks of firm ground which may have a very steep slope greater than the slope of the natural slope and can be around a slope of 80% sinus

En ce qui concerne le dispositif élévateur reliant la trémie de réception et de reprise des matières extraites à la trémie d'alimentation de la pompe, il peut être constitué par un élévateur à godets ou par une vis hélicoïdale gainée dont le débit est choisi légèrement plus fort que les débits totalisés des vis d'extraction et du dispositif extracteur de l'avant de la trémie.Regarding the lifting device connecting the hopper for receiving and taking up the extracted materials to the pump supply hopper, it can be constituted by a bucket elevator or by a sheathed helical screw whose flow rate is chosen slightly more higher than the total flow rates of the extraction screws and of the extractor device from the front of the hopper.

Dans certains cas, ce dispositif élévateur peut être constitué par un châssis rigide, articulé en parties haute et basse de la même manière que l'élévateur à godets ou la vis hélicoïdale gainée, et supportant deux tubes d'aspiration, plongeant dans la trémie de réception à leur extrémité inférieure et adaptés, à leur extrémité supérieure, pour communiquer respectivement avec chacun des deux tubes de la pompe suivant les séquences d' aspiration de ceux-ci.In certain cases, this lifting device can be constituted by a rigid frame, articulated in upper and lower parts in the same way as the bucket elevator or the sheathed helical screw, and supporting two suction tubes, plunging into the hopper of reception at their lower end and adapted, at their upper end, to communicate respectively with each of the two pump tubes according to the aspiration sequences thereof.

On doit noter, en outre, que ce dispositif élévateur, dans tous les cas, porte en tête un bras de levier, relié à la tête du portique de mise en position horizontale de la pompe, au moyen d'un palan, qui lui sert de moyen d'inclinaison et supplée au moyen de liaison réglable entre les assises de base de la pompe et de la trémie de réception, afin de régler celle-ci dans sa position d'avancement vers les matières à extraire.It should also be noted that this lifting device, in all cases, carries a lever arm at the head, connected to the head of the gantry for horizontal positioning of the pump, by means of a hoist, which serves it of tilting means and supplemented by means of adjustable connection between the base layers of the pump and of the receiving hopper, in order to adjust the latter in its advancing position towards the materials to be extracted.

D'autres caractéristiques de la présente invention seront apparentes de la description suivante d'un mode de réalisation, donné à titre d'exemple non limitatif, de l'appareil d'extraction et d'alimentation de matières boueuses à une station de traitement, représenté de manière schématique sur le dessin ci- joint, dans lequel :

  • La figure 1 est une vue en élévation schématique de l'appareil conforme à l'invention, et
  • la figure 2 est une vue en plan, prise suivant les flèches AA et montrant l'ensemble d'extraction avec trémie de réception et de reprise des matières extraites.
Other features of the present invention will be seen rentes of the following description of an embodiment, given by way of nonlimiting example, of the apparatus for extracting and feeding muddy materials at a treatment station, represented schematically in the drawing below joint, in which:
  • FIG. 1 is a schematic elevation view of the apparatus according to the invention, and
  • Figure 2 is a plan view, taken along the arrows AA and showing the extraction assembly with hopper for receiving and taking up the extracted materials.

Comme représenté sur ces figures, on voit que l'appareil conforme à l'invention peut travailler à l'extraction des matières boueuses dans un bassin à rives en forte déclivité et pénétrer dans celui-ci sans risque d'enlisement ou d'effondrement gênant des matières à extraire, puisqu'il peut travailler pour ainsi dire "en butte" dans celles-ci. Il est bien entendu que pour arriver à la position représentée, l'appareil a débuté l'extraction à partir du sommet de la rive et qu'il a commencé à pénétrer dans le bassin lorsque les vis extractrices avaient déjà décapé une assez grande longueur de terre ferme.As shown in these figures, it can be seen that the apparatus according to the invention can work for the extraction of muddy materials in a sharply declining shoreline basin and penetrate therein without the risk of embarrassment getting bogged down or collapsing materials to be extracted, since it can work so to speak "in butt" in them. It is understood that to arrive at the position shown, the apparatus began the extraction from the top of the bank and that it began to penetrate into the basin when the extractor screws had already stripped a fairly large length of land.

Cet appareil selon l'invention comprend, d'amont en aval, une pompe 1 de propulsion des matières extraites vers une station de traitement à distance (non représentée) au moyen d'une canalisation 2, un dispositif élévateur 3 de reprise desdites matières dans une trémie de réception 4 et déversant ces dernières dans la trémie d'alimentation 5 de la pompe, ladite trémie de réception 4, portant latéralement deux vis d'extraction 6 et 7, ainsi que, sur sa partie avant, un dispositif extracteur 8 (représenté en pointillés) pouvant travailler seul ou conjointement avec les vis d'extraction.This device according to the invention comprises, from upstream to downstream, a pump 1 for propelling the materials extracted to a remote treatment station (not shown) by means of a pipe 2, an elevating device 3 for recovering said materials in a receiving hopper 4 and discharging the latter into the supply hopper 5 of the pump, said receiving hopper 4, carrying two extraction screws 6 and 7 laterally, as well as, on its front part, an extractor device 8 ( shown in dotted lines) can work alone or together with the extraction screws.

Comme on le voit au mieux dans la figure 1, la pompe est montée sur une assise de base 9, de manière articulée en 10, afin de pouvoir être mise en position horizontale, alors que l'assise 9, sous forme d'un traîneau ou d'une barge pouvant être pourvue de chenilles, est en position inclinée d'appui sur la rive en déclivité. Cette assise 9 de la pompe est amarrée sur un ancrage 11, au moyen d'un câble 12, avec palan à câbles 13 de réglage, dont le treuil de commande 14 est situé sur le châssis de support de la pompe 1. Sur l'extrémité avant de l'assise 9 est monté, de manière oscillante en 15, un portique 16 portant en tête un palan 17 permettant le soulèvement de la pompe pour sa mise en position horizontale. On remarquera que, bien que cela soit représenté de manière très schématique, les montants du portique 16 sont sous forme de glissières dans lesquelles roulent des galets latéraux 18, solidaires du bâti de la pompe et assurant une position stable au portique dans toutes les positions de cette dernière. A l'extrémité avant de l'assise 9 est amarré un palan 19 de retenue de la trémie 4 de réception et de reprise des matières extraites.As best seen in Figure 1, the pump is mounted on a base seat 9, in an articulated fashion at 10, so that it can be placed in a horizontal position, while the seat 9, in the form of a sled. or a barge that can be provided with tracks, is in an inclined position of support on the bank in slope. This seat 9 of the pump is moored on an anchor 11, by means of a cable 12, with adjusting cable hoist 13, the control winch 14 of which is located on the support frame of the pump 1. On the front end of the seat 9 is mounted, in an oscillating manner at 15, a gantry 16 carrying at the head a hoist 17 allowing the lifting of the pump for its placing in horizontal position. It will be noted that, although this is shown very schematically, the amounts of the gantry 16 are in the form of slides in which roll side rollers 18, integral with the pump frame and ensuring a stable position at the gantry in all the positions of the latter. At the front end of the seat 9 is moored a hoist 19 for retaining the hopper 4 for receiving and taking up the extracted materials.

Cette trémie 4 comporte également une assise de base 20, sous forme d'un traîneau ou d'une barge pouvant être pourvue de chenilles, et supporte sur sa partie arrière, de manière articulée en 21, la partie basse du dispositif élévateur 3, dont la partie haute est articulée en 22 sur un prolongement du bâti de la pompe, pour qu'il déverse les matières extraites dans la trémie d'alimentation 5 de la pompe. A noter que ce dispositif élévateur 3 porte en tête un bras de levier 23, relié par un palan 24 à la tête du portique 16, afin de pouvoir faire varier l'inclinaison de ce dispositif et, en même temps, faire avancer à la demande la trémie 4 en relâchant toutefois le palan 19 sans que la pompe 1 soit changée de position.This hopper 4 also comprises a base seat 20, in the form of a sled or a barge which can be provided with tracks, and supports on its rear part, in an articulated manner at 21, the lower part of the lifting device 3, of which the upper part is articulated at 22 on an extension of the pump frame, so that it pours the materials extracted into the feed hopper 5 of the pump. Note that this lifting device 3 carries a lever arm 23 at the head, connected by a hoist 24 to the head of the gantry 16, in order to be able to vary the inclination of this device and, at the same time, advance on demand the hopper 4, however, releasing the hoist 19 without the pump 1 being changed position.

On doit remarquer que le dispositif élévateur 3 est représenté dans les figures sous forme d'un élévateur à godets, mais qu'il peut être constitué également par une vis hélicoïdale gainée ou encore par un châssis rigide supportant deux tubes d'aspiration communiquant respectivement avec les tubes de la pompe en fonction des séquences respectives d'aspiration de ceux-ci.It should be noted that the lifting device 3 is shown in the figures in the form of a bucket elevator, but that it can also be constituted by a sheathed helical screw or by a rigid frame supporting two suction tubes communicating respectively with the pump tubes according to their respective suction sequences.

Comme on le voit au mieux dans la figure 2, la trémie 4 supporte de manière articulée, à l'avant, le dispositif extracteur axial 8 et, latéralement, les vis d'extraction 6 et 7. Chacune de ces vis est montée de manière à pouvoir pivoter latéralement sous l'action d'un vérin respectif 23, ou tout autre moyen semblable, et décrire un angle d'approximativement 90° par rapport à l'axe longitudinal de l'appareil et, en outre, de manière à pouvoir être relevée ou abaissée au moyen d'un palan respectif 24, amarré en tête d'un portique 25 supporté par la trémie 4.As best seen in Figure 2, the hopper 4 hingedly supports, at the front, the axial extractor device 8 and, laterally, the extraction screws 6 and 7. Each of these screws is mounted so to be able to pivot laterally under the action of a respective jack 23, or any other similar means, and to describe an angle of approximately 90 ° relative to the longitudinal axis of the apparatus and, moreover, so as to be able to be raised or lowered by means of a respective hoist 24, moored at the head of a gantry 25 supported by the hopper 4.

Par ailleurs, chaque vis d'extraction, commandée en rotation par un moteur indépendant 26,27, est pourvue, à son extrémité avant, d'une ogive 28,29 rotative et protectrice, laissée nue dans sa partie avant d'extraction et gainée sur le reste de sa longueur, avec, en tête, un couloir d'écoulement des matières extraites dans la trémie 4. Chaque vis comporte en outre, sous sa partie gainée et en avant de cette trémie, un volet inférieur 30, réglable en hauteur et adapté pour faire office de patin d'appui de la vis, en même temps que dispositif de raclage et de nivellement du terrain, lorsque la vis est ramenée longitudinalement à la trémie, les matières raclées pouvant ainsi être reprises par le dispositif extracteur 8.Furthermore, each extraction screw, controlled in rotation by an independent motor 26,27, is provided, at its front end, with a rotary and protective warhead 28,29, left bare in its front extraction part and sheathed over the rest of its length, with, at the head, a flow corridor for the materials extracted in the hopper 4. Each screw further comprises, under its sheathed part and in front of this hopper, a lower flap 30, adjustable in height and adapted to act as a support pad for the screw, at the same time as a scraper and leveling device for the ground, when the screw is brought back longitudinally to the hopper, the scraped materials can thus be taken up by the extractor device 8.

On remarquera que dans ce mode de réalisation représenté dans les figures 1 et 2, chaque palan est montré sous forme d'un palan à câble mouflé, mais que tout autre type de palan peut être utilisé sans modifier les caractéristiques de l'appareil conforme à l'invention.It will be noted that in this embodiment represented in FIGS. 1 and 2, each hoist is shown in the form of a wire rope hoist, but that any other type of hoist can be used without modifying the characteristics of the apparatus in accordance with the invention.
