Description

L'invention a pour objet une cuve, notamment une cuve de appelée souvent digesteur; ces cuves sont destinées au stockage et/ou à la fermentation de produits naturels tels que herbe, fourrage vert, mais, luzerne, mais aussi à la production du biogaz par fermentation de fumier et tout autre déchet organique.The invention relates to a tank, in particular a tank often called a digester; these tanks are intended for the storage and / or fermentation of natural products such as grass, green fodder, but, alfalfa, but also for the production of biogas by fermentation of manure and any other organic waste.

connaft ces cuves depuis longtemps; il s'agit notamment des cuves d'ensilage. On les construit à présent sur mésure en pièces métalliques préfabriquées, tenues ou non par une charpente de renforcement et de support; très souvent elles sont en béton armé. Les désavantages majeurs de telles cuves sont d'abord le fait que leurs pièces doivent être fabriquées sur mesure et doivent être assemblées par des procédés longs et couteux comme par rivetage et par soudure (car la cuve doit être étanche), et que le prix de ces cuves est très élevé, de par le prix de la matière métallique qui monte sans cesse et par le coût de l'assemeblage. En règle générale, ces cuves doivent être isolées en plus lorsqu'il s'agit de digesteurs afin que la fermentation ne soit pas arrêtée. En plus, les cuves en béton sont beaucoup trop lourdes.have known these tanks for a long time; these include silage tanks. They are now built to measure in prefabricated metal parts, held or not by a reinforcement and support frame; very often they are made of reinforced concrete. The major disadvantages of such tanks are first of all the fact that their parts must be custom-made and must be assembled by long and expensive processes such as riveting and welding (because the tank must be waterproof), and that the price of these tanks are very high, by the price of the metallic material which goes up constantly and by the cost of the assembly. As a general rule, these tanks must be additionally isolated in the case of digesters so that fermentation is not stopped. In addition, the concrete tanks are much too heavy.

La présente invention s'est donnée comme but de supprimer tous ces inconvénients et de proposer une nouvelle cuve facile à monter et bon marché, en utilisant en principe un matériau existant non métallique.The object of the present invention is to eliminate all these drawbacks and to propose a new tank which is easy to assemble and inexpensive, in principle using an existing non-metallic material.

Ce but est accompli par la cuve selon l'invention qui est caractérisée en ce que ces parois sont formées d'éléments modulaires alvéolés en amiante-ciment extrudé, à faces planes et parallèles, la section horizontale de la cuve étant polygonale.This object is accomplished by the tank according to the invention which is characterized in that these walls are formed of modular cellular elements made of extruded asbestos-cement, with flat and parallel faces, the horizontal section of the tank being polygonal.

Des éléments modulaires alvéolés en amiante-ciment extrudé sont déjà connus. Il s'agit par exemple de panneaux appelés "Wallbord" de la société américaine Johns-Manville. Cette matière se distingue par une densité bien inférieure à celle des métaux (environ 1,6 kg/1), une résistance à la flexion d'au moins 200 kg/cm 2 et une ré- sistance à la compression de 450 kg/cm . Les éléments modulaires sont des panneaux à double ou à triple paroi, 30 ou 60 cm de large, 6, & ou 10 cm d'épais et jusqu'à 6 m de long, munis d'emboîtement mâle et femelle sur les côtés latérales pour faciliter l'assemblage à plat. Il sera expliqué plus bas que ces panneaux, tels qu'ils sont disponibles sur le marché, ne peuvent pas être utilisés sans une modification importante faisant partie de l'invention.Modular honeycomb elements made of extruded asbestos cement are already known. These are for example panels called "Wallbord" from the American company Johns-Manville. This material is distinguished by a density much lower than that of metals (approximately 1.6 kg / 1), a flexural strength of at least 200 kg / cm 2 and a compressive strength of 450 kg / cm . The modular elements are double or triple wall panels, 30 or 60 cm wide, 6, & or 10 cm thick and up to 6 m long, with male and female interlocking on the lateral sides for facilitate flat assembly. It will be explained below that these panels, as they are available on the market, cannot be used without a significant modification forming part of the invention.

A des fins de commodité seulement, on appelera ci-après les emboîtements femelle et mâle "rainure et languette" bien que l'emboîtement mâle puisse lui-même être muni d'une rainure et qu'il soit plus large qu'une languette ordinaire.For convenience only, the female and male sockets will hereinafter be called "tongue and groove" although the male socket may itself have a groove and be wider than an ordinary tongue .

Les autres propriétés des éléments modulaires utilisés selon l'invention sont également très intéressantes en fonction du but visé. On citera le poids, assez faible, de 50 kg environ par m , étanchéité complète, les propriétés anti-feu (la matière est absolument incombustible ininflammable), le fait que les plaques sont imputrescibles, à scier, à coller, à percer, à tarauder et à peindre, ont des propriétés isolantes moyennes (conductivité thermique de 2,1 kcal/m2h°C) et à peu près le même coefficient de dilatation que celui de l'acier.Other properties of modular elements used according to the invention are also very interesting depending on the aim. We can cite the fairly low weight of around 50 kg per m, complete sealing, fire-resistant properties (the material is absolutely non-combustible non-flammable), the fact that the plates are rot-proof, to saw, to glue, to drill, to tapping and painting, have average insulating properties (thermal conductivity of 2.1 kcal / m 2 h ° C) and roughly the same coefficient of expansion as that of steel.

On peut également chauffer ou refroidir les panneaux en disposant des radiateurs électriques tubulaires à l'intérieur des alvéoles qui s'étendent tout le long à l'intérieur des panneaux, ou en passant de l'air chaud ou froid par ces alvéoles.The panels can also be heated or cooled by having tubular electric radiators inside the cells which extend all the way inside the panels, or by passing hot or cold air through these cells.

Une autre avantage des panneaux alvéolés en amiante-ciment utilisés selon l'invention réside dans le fait qu'ils peuvent être très rapidement assemblés "à sec", c'est-à-dire sans mortier ou d'autres liants hydrauliques mais par collage, de préférence à une colle au silicone qui reste élastique même après sont auto- vulcanisation, ou à une colle époxy connue en soi.Another advantage of the asbestos-cement honeycomb panels used according to the invention lies in the fact that they can be very quickly assembled "dry", that is to say without mortar or other hydraulic binders but by bonding. , preferably to a silicone adhesive which remains elastic even after self-vulcanization, or to an epoxy adhesive known per se.

L'invention sera encore mieux comprise à l'aide de la description d'un exemple de réalisation qui suit, en se référant au dessin sur lequel:

  • - la fig. 1 montre une vue en plan, partagée entre la partie couvrante (à gauche) et la partie de base (à droite), d'une cuve selon l'invention,
  • - la fig. 2 est une coupe centrale selon la ligne II-II de la fig. 1,
  • - la fig. 3 représente en coupe un panneau "Wallboard" du commerce, non utilisable sans autre,
  • - la fig. 3A est une représentation schématique d'un bord de la filière,
  • - la fig. 4 est une section transversale d'une liaison de deux éléments alvéolés ayant subi la modification selon l'invention sur la rainure, et
  • - la fig. 5 est une section transversale d'une liaison de deux éléments alvéolés ayant subi la modification selon l'invention sur la languette.
The invention will be understood more clearly with the aid of the description of an exemplary embodiment which follows, with reference to the drawing in which:
  • - fig. 1 shows a plan view, shared between the covering part (on the left) and the base part (on the right), of a tank according to the invention,
  • - fig. 2 is a central section on the line II-II of FIG. 1,
  • - fig. 3 represents in section a commercial "Wallboard" panel, which cannot be used without other,
  • - fig. 3A is a schematic representation of an edge of the die,
  • - fig. 4 is a cross section of a connection of two honeycomb elements which have undergone the modification according to the invention on the groove, and
  • - fig. 5 is a cross section of a connection of two honeycomb elements having undergone the modification according to the invention on the tongue.

La cuve qui est représentée aux fig. 1 et 2 a une capacité de 350 m3 environ, à savoir un diamètre intérieur de 8 m, une hauteur de la partie cylindrique de 6 m (la longueur normale des panneaux) et une hauteur des parties en bas et en haut de 1,40 et de 1,8 m, respectivement.The tank which is represented in fig. 1 and 2 has a capacity of approximately 350 m 3 , namely an internal diameter of 8 m, a height of the cylindrical part of 6 m (the normal length of the panels) and a height of the parts at the bottom and at the top of 1, 40 and 1.8 m, respectively.

La cuve repose sur une ceinture de base 1 et une plaque de fond 2 qui sont coulées en béton armé sur place; elles peuvent également être en métal. Les pièces 1 et 2 sont réunies par des poutres radiales 3 en béton ou métal sur lesquelles sont posées les panneaux en amiante-ciment de fond 4, collés entre eux et sur les poutres 3. Un chauffage électrique ou à air pulsé, indiqué par 5, peut être prévu dans les alvéoles des panneaux 4.The tank rests on a base belt 1 and a bottom plate 2 which are poured in reinforced concrete on site; they can also be made of metal. Parts 1 and 2 are joined by radial beams 3 of concrete or metal on which are placed the bottom asbestos-cement panels 4, glued together and on the beams 3. Electric or forced air heating, indicated by 5 , can be provided in the cells of the panels 4.

La paroi cylindrique ou plus exactement polygonale 6 de la cuve est formée par des panneaux 7 posés de façon que leur longueur fait la hauteur de la cuve. Les panneaux peuvent être munis de corps de chauffe 14. Dans la fig. 3, on a représenté un tel panneau, désigné comme 7', tel qu'il se trouve dans le commerce. On voit immédiatement qu'il n'est pas possible de former un cercle ou plus exactement un polygone ayant un nombre raisonnablement bas de coins (et donc un diamètre pas trop élevé) par emboîtement des languettes 8' dans les rainures 9'; ou bien ces organes se cassent ou bien l'emboîtement ne peut se faire.The cylindrical or more exactly polygonal wall 6 of the tank is formed by panels 7 placed so that their length makes the height of the tank. The panels can be provided with heating bodies 14. In fig. 3, there is shown such a panel, designated as 7 ', as it is commercially available. We immediately see that it is not possible to form a circle or more exactly a polygon having a reasonably low number of corners (and therefore a diameter not too high) by fitting the tongues 8 'in the grooves 9'; either these organs break or the nesting cannot be done.

Il est donc un autre aspect de l'invention de prévoir des panneaux modifiés, voir les figs. 4 et 5. Dans le panneau 7A qui est réuni avec le panneau 7B, la ligne pointillée A indique la forme de la rainure avant modification, et la partie 10 constitue cette modification comprenant donc du matériel ajouté en "pivotant" l'orientation d3 la rainure par l'angle α = 360/x où x est le nombre de panneaux faisant le polygone de la cuve. Cet angle est de 360 : 42 = 8,6° environ dans le cas de la cuve représentée (fig. 1 et 2), donc pas négligeable pour une cuve ayant le diamètre de 8 m déjà assez grand.It is therefore another aspect of the invention to provide modified panels, see figs. 4 and 5. In panel 7A which is joined with panel 7B, the dotted line A indicates the shape of the groove before modification, and part 10 constitutes this modification therefore comprising material added by "pivoting" the orientation d3 the groove by the angle α = 360 / x where x is the number of panels making the polygon of the tank. This angle is 360: 42 = 8.6 ° approximately in the case of the tank represented (fig. 1 and 2), therefore not negligible for a tank having the diameter of 8 m already large enough.

Le tableau suivant donne un aperçu des angles α en jeu:

Figure imgb0001
Les angles sont donc assez importants.The following table gives an overview of the angles α involved:
Figure imgb0001
 The angles are therefore quite large.

La deuxième possibilité de modification consiste en "pivotant" la languette du panneau par l'angle α, voir fig. 5. Le profil d'origine est désigné par la ligne pointillée A tandisque la partie l0A a été ajoutée pour égaliser l'angle α du polygone faisant la cuve. Les panneaux réunis portent les numéros de référence 7C et 7D.The second possibility of modification consists in "pivoting" the tab of the panel by the angle α, see fig. 5. The original profile is designated by the dotted line A while part 10A has been added to equalize the angle α of the polygon making the tank. The assembled panels bear the reference numbers 7C and 7D.

Il est également possible de modifier la rainure et la languette simultanément, chacune par l'angle ½α. Une exécution préférée, non représentée mais parfaitement compréhensible, consiste en ne pas ajouter de la matière pour obtenir l'angle α ou ½α, respectivement, mais d'en enlever des parois latérales et longitudinales des panneaux. La raison pratique de cette mesure se fonde sùr le fait que dans ce cas, il suffit de munir un bord latéral de la filière produisant les panneaux par extrusion, ou les deux bords, de petites caches qui, lors de l'extrusion, empêchent la sortie de la matière, voir Fig. 3A où l'ouverture 11 de la filière, au bord produisant la rainure, est partiellement obstruée par-la cache 12' donnant une rainure modifiée ("pivotée") par l' angle α.It is also possible to modify the groove and the tongue simultaneously, each by the angle ½α. A preferred embodiment, not shown but perfectly understandable, consists in not adding material to obtain the angle α or ½α, respectively, but in removing side and longitudinal walls of the panels. The practical reason for this measure is based on the fact that in this case, it suffices to provide a lateral edge of the die producing the panels by extrusion, or both edges, with small covers which, during extrusion, prevent the out of the material, see Fig. 3A where the opening 11 of the die, at the edge producing the groove, is partially obstructed by the cover 12 'giving a modified groove ("pivoted") by the angle α.

Retournant aux fig. 1 et 2, on voit que les panneaux verticaux 7 sont radialement précontraints par les cerceaux ou câbles métalliques extérieurs 12, vissés et serrés au moyen des vis et écrous aux endroits 13. La cuve se termine vers le haut par la plaque métallique 15 ayant un trou d'homme 16 qui sert également d'ouverture pour l'évacuation des gaz. La plaque 15, éventuellement renforcée par des nervures 21, est réunie à des plaques métalliques 17 par les poutres en doùble-T 18 dont les ailes recoivent les panneaux 19; le double T sert à retenir les panneaux contre une pression interne:. La plaque 15 est pouvue d'une isolation 20. Les alvéoles des plaques peuvent être remplies d'une matière isolante.Returning to Figs. 1 and 2, it can be seen that the vertical panels 7 are radially prestressed by the hoops or external metal cables 12, screwed and tightened by means of the screws and nuts at the places 13. The tank ends upwards by the metal plate 15 having a manhole 16 which also serves as an opening for the evacuation of gases. The plate 15, possibly reinforced by ribs 21, is joined to metal plates 17 by the double-T beams 18 whose wings receive the panels 19; the double T is used to hold the panels against internal pressure :. Plate 15 is provided with an insulation 20. The cells of the plates can be filled with an insulating material.

La cuve peut être montée en très peu de temps. On procède généralement comme suit: On coule la plaque de fond 2 et la ceinture de support 1, en réunissant les deux coulages par les poutres 3. Après durcissement, on pose les panneaux 4 en les collant par leurs rainures et languettes au moyen de résine époxy. Les parois verticales 6 sont montées de la même façon; une fois le pourtour terminé, on pose et serre les cerceaux 12, on ajoute les plaques métalliques 17, les poutres 18 et la plaque 15, et pour finir on pose les panneaux en amiante-ciment 19 ainsi que l'isolation 20. En pratique, il y aura dans certains cas plus de cerceaux que ceux représentés dans la fig. 2.The tank can be assembled in a very short time. We generally proceed as follows: We pour the bottom plate 2 and the support belt 1, joining the two castings by the beams 3. After hardening, we put the panels 4 by gluing them by their grooves and tongues using resin epoxy. The vertical walls 6 are mounted in the same way; once the perimeter is finished, the hoops 12 are laid and tightened, the metal plates 17, the beams 18 and the plate 15 are added, and finally the asbestos-cement panels 19 and the insulation are laid 20. In practice , there will in some cases be more hoops than those shown in fig. 2.

La rigidité de cette construction répond à toutes les exigences bien qu'aucune structure porteuse- hormis les cerceaux 12 - soit prévue. L'invention permet en outre la construction de cuves ayant les dimensions voulues par simple adjonction à la filière produisant les éléments alvéolés en amiante-ciment par extrusion, de petites caches changeant la structure de la languette et/ou de la rainure.The rigidity of this construction meets all the requirements although no supporting structure - apart from the hoops 12 - is provided. The invention also allows the construction of tanks having the desired dimensions by simple addition to the die producing the cellular elements in asbestos-cement by extrusion, small covers changing the structure of the tongue and / or of the groove.

La hauteur de la cuve, à savoir de sa partie cylindrique, peut être quelconque. Si elle est inférieure à 6 m, la longeur normale des panneaux, ceux-ci seront coupés; pour des hauteurs dépassant 6 m, on superpose des panneaux de longueur appropriée.The height of the tank, namely of its cylindrical part, can be arbitrary. If it is less than 6 m, the normal length of the panels, these will be cut; for heights exceeding 6 m, panels of appropriate length are superimposed.

Le fait d'utiliser des panneaux en amiante-ciment décrits ayant des alvéoles sous formes de chambres, offre l'avantage supplémentaire de pouvoir y placer une matière isolante qui est alors à l'abri sans que l'on ait besoin d'une protection spéciale. De préférence, on injecte dans les alvéoles une masse formant mousse, par exemple une masse à deux composants (polyol et polyisocyanate) donnant un polyuréthane mousse, hydrophobe ou imperméable à l'eau.The use of asbestos panels- Cement described having cells in the form of chambers, offers the additional advantage of being able to place an insulating material which is then sheltered without the need for special protection. Preferably, a foam-forming mass is injected into the cells, for example a two-component mass (polyol and polyisocyanate) giving a foam polyurethane, hydrophobic or waterproof.

Afin de parfaire l'étanchéité de la cuve, notamment en ce qui concerne l'eau et la vapeur d'eau, il est avantageux d'appliquer à l'intérieur de toute la cuve, une couche d'imperméabilisation, par exemple une laque de matière plastique comme le polyurethane, le chlorure de polyvinyle, le polyéthylène, le téflon, le nylon etc.In order to complete the tightness of the tank, in particular with regard to water and water vapor, it is advantageous to apply to the interior of the entire tank, a waterproofing layer, for example a lacquer plastic materials such as polyurethane, polyvinyl chloride, polyethylene, teflon, nylon etc.

La cuve peut être munie d'un chauffage interne, par exemple des corps de chauffe ou des dispositifs pour injecter de la vapeur d'eau, ou bien d'une installation de-refroidissement.The tank may be provided with internal heating, for example heating bodies or devices for injecting steam, or else with a de-cooling installation.

La cuve peut également être utilisé comme réservoir d'eau chaude, d'eau froide, comme cuve d'ensilage, cuve d'accumulation, etc.The tank can also be used as a hot water tank, cold water tank, as a silage tank, accumulation tank, etc.
