PRESSE A VIS
L'invention se rapporte à une presse à vis. SCREW PRESS
The invention relates to a screw press.
Classiquement, une presse à vis comprend un fourreau perméable dans lequel sont logées au moins deux vis coaxiales alignées au long d'un axe commun et écartées les unes des autres par au moins une bague.
Un arbre commun entraîne en rotation l'ensemble des vis et bagues. L'assemblage des vis et des bagues est conçu pour provoquer à la fois une pression de la matière par différence de volume d'une vis à l'autre et une avance progressive de la matière. A common shaft rotates all of the screws and rings. The assembly of the screws and the rings is designed to cause both a pressure of the material by difference in volume from one screw to another and a progressive advance of the material.
Chaque bague est de diamètre externe inférieur au diamètre du fourreau et au niveau de la zone occupée par chaque bague, la face interne du fourreau présente en saillie, au moins une lame dont la fonction est d'immobiliser en rotation la matière pressée. Each ring has an external diameter less than the diameter of the sheath and at the level of the zone occupied by each ring, the internal face of the sheath projecting, at least one blade whose function is to immobilize the pressed material in rotation.
Du fait de cet arrêt en rotation, le déplacement de la matière dépend de la poussée de la matière en amont. Because of this rotational stop, the movement of the material depends on the thrust of the material upstream.
Il se forme donc localement et temporairement un effet de ralentissement de la matière qui permet d'augmenter momentanément la pression interne pour extraire la phase liquide ou l'eau. There is therefore formed locally and temporarily a material slowing effect which temporarily increases the internal pressure to extract the liquid phase or the water.
On constate qu'avec certaines boues liquides chargées en fibres, il se produit des bouchons au niveau de ces bagues. It is found that with certain liquid sludges loaded with fibers, there are plugs at these rings.
En effet, la matière qui arrive n'est pas suffisamment consistante pour exercer une pression sur la matière située au niveau de cette bague. In fact, the material arriving is not sufficiently consistent to exert pressure on the material located at the level of this ring.
Par ailleurs, les fibres que la matière contient s'accumulent au niveau des lames et forment alors un bouchon. Furthermore, the fibers that the material contains accumulate at the level of the blades and then form a plug.
La capacité de la presse devient alors très faible. The capacity of the press then becomes very low.
L'invention se propose de remédier notamment aux inconvénients précités. The invention proposes to remedy in particular the aforementioned drawbacks.
A cet effet, l'invention a pour objet une presse à vis comprenant : - un fourreau perméable dans lequel sont logées au moins deux vis coaxiales alignées au long d'un axe commun et écartées les unes des autres par au moins une bague de diamètre externe inférieur au diamètre du fourreau, - au niveau de la zone occupée par chaque bague, en saillie sur la face interne du fourreau, au moins une lame s'étendant selon une génératrice du fourreau, To this end, the subject of the invention is a screw press comprising: - a permeable sheath in which are housed at least two coaxial screws aligned along a common axis and spaced from each other by at least one ring of diameter external less than the diameter of the sheath, - at the level of the zone occupied by each ring, projecting from the internal face of the sheath, at least one blade extending along a generatrix of the sheath,
<Desc/Clms Page number 2><Desc / Clms Page number 2>
cette presse a vis étant caractérisée en ce qu'au moins une bague est pourvue d'une spire d'une vis. this screw press being characterized in that at least one ring is provided with a turn of a screw.
L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement : - figure 1 : état antérieur à la technique - figure 2 à 4 : presse à vis selon l'invention. The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the appended drawing which schematically represents: - Figure 1: prior art - Figure 2 to 4: screw press according to the invention.
En se reportant au dessin, on voit une presse à vis. Referring to the drawing, we see a screw press.
Classiquement, une presse à vis 1 comprend : - un fourreau 2 perméable dans lequel sont logées au moins deux vis coaxiales 3 alignées au long d'un axe commun et écartées les unes des autres par au moins une bague 4 de diamètre externe inférieur au diamètre du fourreau, - au niveau de la zone occupée par chaque bague 4, en saillie sur la face interne du fourreau, au moins une lame 5 s'étendant selon une génératrice du fourreau. Conventionally, a screw press 1 comprises: - a permeable sheath 2 in which are housed at least two coaxial screws 3 aligned along a common axis and spaced from each other by at least one ring 4 of external diameter less than the diameter of the sheath, - at the level of the zone occupied by each ring 4, projecting from the internal face of the sheath, at least one blade 5 extending along a generatrix of the sheath.
Au niveau de chaque bague, sont positionnées généralement deux lames 5 diamétralement opposées. At each ring, two diametrically opposed blades 5 are generally positioned.
Si l'on se réfère aux figures, la matière est introduite par une ouverture 6 aménagée dans le fourreau (à gauche du dessin) puis progressivement progresse vers la droite. If we refer to the figures, the material is introduced through an opening 6 arranged in the sheath (to the left of the drawing) then progressively progresses towards the right.
La sortie 7 du fourreau est partiellement obturée par une tête 8 de sorte qu'il se produit nécessairement un effet d'accumulation de la matière et donc un ralentissement de la matière induisant ainsi une augmentation de pression. The outlet 7 of the sheath is partially closed off by a head 8 so that there is necessarily an effect of accumulation of the material and therefore a slowing down of the material thus inducing an increase in pressure.
Les vis 3 et bagues 4 sont calées en rotation sur un arbre commun 9 mu par un moteur. The screws 3 and rings 4 are locked in rotation on a common shaft 9 driven by a motor.
En figure 1, il a été représenté un système de l'art antérieur. On voit que les bagues 4 sont lisses extérieurement. In Figure 1, there is shown a system of the prior art. It can be seen that the rings 4 are smooth on the outside.
Selon l'invention au moins une bague 4 est pourvue d'un filet 4A de vis. According to the invention at least one ring 4 is provided with a thread 4A of screws.
Le pas de ce filet de vis est soit égal au pas des vis de pression soit différent. The pitch of this screw thread is either equal to the pitch of the pressure screws or different.
Le filet de vis s'étend sur toute la longueur de la bague ou sur une partie de cette longueur. The screw thread extends over the entire length of the ring or over a part of this length.
Lorsque le filet de vis s'étend sur toute la longueur de la vis, les deux extrémités de ce filet de vis peuvent coïncider avec les extrémités des filet des vis de pression (figure 2) toutefois cette disposition n'est pas obligatoire. When the screw thread extends over the entire length of the screw, the two ends of this screw thread may coincide with the ends of the pressure screw threads (Figure 2), however this arrangement is not compulsory.
<Desc/Clms Page number 3> <Desc / Clms Page number 3>
Lorsque les extrémités coïncident, il n'y a pas de rupture dans l'acheminement de la matière. When the ends coincide, there is no break in the flow of the material.
La hauteur du filet de vis équipant ces bagues intermédiaires est inférieure à la hauteur du filet des vis de pression de sorte que les lames 5 en saillie conservent leur effet anti-rotation sur la masse de matière située en périphérie. The height of the screw thread equipping these intermediate rings is less than the height of the pressure screw thread so that the projecting blades 5 retain their anti-rotation effect on the mass of material located at the periphery.
La hauteur de ces lames anti-rotation doit rester suffisamment importante pour conserver sa fonctionnalité. The height of these anti-rotation blades must remain large enough to maintain its functionality.
Le filet de vis équipant la bague provoque une évacuation partielle du bouchon et libère donc une partie de la section de passage. The thread of screw equipping the ring causes a partial evacuation of the plug and therefore frees part of the passage section.
Dans une forme de réalisation (figure 4), entre deux vis 3 de pression, on monte deux bagues 4 équipées chacune d'un filet de vis. In one embodiment (FIG. 4), between two pressure screws 3, two rings 4 are fitted, each equipped with a screw thread.
Les filets des bagues peuvent alors être déphasés pour produire une rupture dans l'acheminement et ainsi localement produire une pression plus importante. The threads of the rings can then be out of phase to produce a break in the routing and thus locally produce greater pressure.
Même si ces filets de vis se complètent, il se produit cependant une augmentation de la pression. Even if these screw threads complement each other, however, there is an increase in pressure.
Dans une autre variante de réalisation, le filet de vis équipant la bague intermédiaire est opposé à ceux équipant les vis de pression. In another alternative embodiment, the screw thread equipping the intermediate ring is opposite to those equipping the pressure screws.
On obtient un brassage de la matière à l'intérieur du fourreau. We obtain a mixing of the material inside the sheath.
La matière étant donc retournée et freinée, on peut augmenter l'efficacité de la presse. The material being therefore turned over and braked, the efficiency of the press can be increased.
Il faut toutefois limiter la longueur de la spire inversée et/ou la hauteur de celle-ci pour éviter de créer un blocage. It is however necessary to limit the length of the inverted turn and / or the height of this to avoid creating a blockage.
