Abstract

A vessel for producing compost by fermentation of organic waste e.g. sewage sludge, stable manure etc.. The vessel is a vertical column which is loaded at the top and has a horizontal, screw conveyor to discharge fermented material at the bottom. The vessel is now of square or rectangular cross-section so that several can be fitted flush against each other. The discharge conveyor can be displaced laterally in a horizontal direction to sweep beneath the whole base area of one or several adjacent vessels.

Description

Pour transformer industriellement en compost les de- chets organiques, et, plus spécialement, les ordures ménagères et les boues organiques, conditionnées ou non, on utilise des tours de fermentation, que l'on remplit par le haut, et dont on retire, à la partie inférieure, les produits de ia fermentation intervenue, de façon continue ou non. To industrially transform organic waste, and more specifically, household waste and organic sludge, conditioned or not, into fermentation compost, fermentation towers are used, which are filled from above, and from which they are removed. the lower part, the products of ia fermentation, whether continuous or not.

nes tours de fermentation sont généralement cylindriques et doivent comporter chacune tout l'appareillage nécessaire pour leur remplissage et l'évacuation des produits obtenus, pour permettre de pulvériser de l'eau aux niveaux et en quantité désirés,pour apporter l'oxygène nécessaire au développement des microorganismes aérobie, pour surveiller que la fermentation se fait dans de bonnes conditions à chacun des niveaux de la tour, et, éventuellement, pour apporter les corrections nécessaires pour outil en soit ainsi et pour entratner les gaz produits au cours de ia fermentation. our fermentation towers are generally cylindrical and must each include all the equipment necessary for their filling and the evacuation of the products obtained, to allow spraying of water at the desired levels and quantity, to provide the oxygen necessary for development aerobic microorganisms, to monitor that the fermentation is taking place in good conditions at each level of the tower, and, optionally, to make the necessary corrections for this tool and to entrain the gases produced during the fermentation.

La présente invention a pour objet une installation pour la transformation des dechets organiques en compost, comportant au moins une tour de fermentation avec-des moyens pour son remplissage par le haut, et une vis horizontale rotative à a partie inférieure pour l'évacuation des produits traités, Ca- ractérisée en ce que cette tour est parallélépipédique, de section préférablement carrée ou rectangulaire, et que sa vis d'évacuation horizontale, susceptible d'hêtre entraînez en rotation continue ou discontinue autour de son axe, peut également être animée d'un mouvement de translation, continu ou discontinu, pérpendiculairement à cet axe, de façon à pouvoir intervenir sur toute la section de la tour.  The subject of the present invention is an installation for converting organic waste into compost, comprising at least one fermentation tower with means for filling it from above, and a horizontal rotary screw with a lower part for discharging the products. treated, Characterized in that this tower is parallelepiped, of preferably square or rectangular section, and that its horizontal discharge screw, capable of being driven in continuous or discontinuous rotation around its axis, can also be animated by a translational movement, continuous or discontinuous, perpendicular to this axis, so as to be able to intervene over the entire section of the tower.

L'installation comporte préférablement plusieurs tours parallélépipédiques accolées en ligne, de la même dimension, ou éventuilement de dimensions différentes, et un même appareillage pour le remplissage de plusieurs, ou éventuellement de toutes ces tours accolées, et, également un même appareillage, pour l'évacua- tion du compost formé dans plusieurs, ou éventuellement toutes ces tours accolées. The installation preferably comprises several parallelepipedic towers placed side by side, of the same dimension, or possibly of different dimensions, and the same apparatus for filling several, or possibly all these contiguous towers, and, also the same apparatus, for the 'disposal of the compost formed in several, or possibly all these adjoining towers.

Chacune de ces tours peut travailler de façon indépendatte et être agencée de façon à assurer la fermentation complète des déchets introduits à sa partie'supérieure, ou,toutes ces tours, ou au moins certaines d'entre elles, peuvent travailler en série, la fermentation étant fractionnée en plusieurs stades, dont chacun se fait dans une tour différente, le produit en cours de traitement passant successivement d'une tour à une autre ou repassant dans la même tour (recyclage). Each of these towers can work independently and be arranged to ensure the complete fermentation of the waste introduced at its upper part, or, all these towers, or at least some of them, can work in series, the fermentation being divided into several stages, each of which is carried out in a different tower, the product being processed passing successively from one tower to another or ironing in the same tower (recycling).

On peut compléter l'installation, au fur et à mesure des besoins, s'ils sont croissants, par de nouvelles tours, accolées en ligne à celles déjà existantes. We can complete the installation, as and when required, if they are growing, by new towers, joined in line with those already existing.

Le dessin annexé montre schématiquement à titre d'exemple un mode de réalisation d'une installation suivant la présente invention
La figure 1-est une oue en élévation.The accompanying drawing shows schematically by way of example an embodiment of an installation according to the present invention
Figure 1-is a view in elevation.

La figure 2 est une vue en coupe transversale. Figure 2 is a cross-sectional view.

L'installation représentée est constituée de quatre tours parallélépipédiques 1, 2, 3 et 4, de section carrée; semblables, accolées en ligne les unes aux autres, alimentées par un seul appareil élévateur 5, qui peut distribuer les matières à traiter sur un tapis sans fin 6; ce tapis peut être déplacé longitudinalement au dessus des ouvertures 7 prévues pour le déversement de produit, et assurer un bon étalement dans les tours; il est susceptible de tourner dans un sens ou dans l'autre et, par conséquent d'alimenter soit la tour 1 et la tour 3, soit la tour 2 et la tour 4, suivant sa position et son sens de rotation. The installation shown consists of four parallelepipedic towers 1, 2, 3 and 4, of square section; similar, joined in line with one another, fed by a single lifting device 5, which can distribute the materials to be treated on an endless belt 6; this mat can be moved longitudinally above the openings 7 provided for the product spill, and ensure good spreading in the towers; it is capable of turning in one direction or the other and, consequently, of supplying either tower 1 and tower 3, or tower 2 and tower 4, according to its position and its direction of rotation.

A la partie inférieure de l'installation est disposée une vis sans fin 8, montée sur decx chariots 9 et 10, et que les moteurs 11 et 12 permettent de faire circuler dans un sens ou dans l'autre, d'une extrémité à l'autre de l'installation; ces vis sans fin, peuvent être de tous types, et pas appropriés, à spires dentelées ou non, à pas continu ou non, à pas variable ou non, etc..., suivant la matière traitée; elles entraînent la matière traitée vers un couloir 13, à travers laquelle elle tombe sur un convoyeur 14. At the lower part of the installation is arranged an endless screw 8, mounted on decx carriages 9 and 10, and which the motors 11 and 12 allow to circulate in one direction or the other, from one end to the 'other of the installation; these endless screws can be of all types, and not suitable, with serrated turns or not, with continuous pitch or not, with variable pitch or not, etc., depending on the material treated; they entrain the treated material towards a corridor 13, through which it falls on a conveyor 14.

On conçoit qu'il est facile d'augmenter la capacité d'une telle installation, en cas de besoin, en la prolongeant par une ou plusieurs autres tours accolées en ligne, dont le prix de revient est inférieur à celui d'une tour cylindrique isolée, et on peut éventuellement utiliser le même appareil-élévateur 5 et la meme vis sans fin 8 pour ces tours complémentaires. It will be appreciated that it is easy to increase the capacity of such an installation, if necessary, by extending it with one or more other towers placed side by side, the cost price of which is lower than that of a cylindrical tower. isolated, and one can possibly use the same lifting device 5 and the same worm 8 for these complementary turns.

Il est bien entendu que le mode de réalisation de l'invention qui a été décrit ci-dessus en référence au dessin annexé a été donné à titre purement indicatif et nullement limitatif et que de nombreuses modifications peuvent être apportées sans qu'on s'écarte pour cela du cadre de la présente invention.  It is understood that the embodiment of the invention which has been described above with reference to the appended drawing has been given for information only and is in no way limitative and that numerous modifications can be made without departing from the scope. for this the scope of the present invention.
