Description
La présente invention concerne un broyeur sanitaire pour installation de relevage des eaux usées et de déchets solides, du type comportant un caisson recevant les eaux et un moteur électrique dont l'axe présente à une extrémité une pompe à rotor à pales et des moyens de broyage en regard d'une chambre de dilacération définie entre le fond du caisson et une paroi périphérique munie d'une ouverture d'entrée.The present invention relates to a sanitary grinder for sewage and waste lifting plant solids, of the type comprising a caisson receiving the waters and an electric motor whose axis has at one end a impeller pump with blades and grinding means opposite a dilaceration chamber defined between the bottom of the box and a peripheral wall with an opening input.
Ces broyeurs sanitaires sont généralement disposés derrière la cuvette des toilettes. Ils peuvent également recevoir les eaux usées d'autres appareils sanitaires. Ils peuvent en outre être encastrés dans une cloison technique.These sanitary grinders are usually arranged behind the toilet bowl. They can also receive wastewater from other sanitary equipment. They can besides being embedded in a technical partition.
Certains broyeurs sanitaires comportent une lame de dilacération des matières solides montée à l'extrémité d'un axe du moteur près de la sortie de la cuvette des toilettes. Seules l'eau et les matières solides suffisamment broyées passent à travers les trous d'une crépine cylindrique vers un réservoir pour y être aspirées par une pompe située dans le fond du réservoir et montée à l'autre extrémité du moteur. Some sanitary grinders have a blade of maceration of the solids mounted at the end of a motor shaft near the exit of the toilet bowl. Only water and solids sufficiently crushed pass through the holes of a cylindrical strainer to a tank to be sucked in by a pump located in the bottom of the tank and mounted at the other end of the engine.
Ce type d'appareil présente un certain nombre d'inconvénients : les produits fibreux tels que lingettes ou serviettes périodiques qui sont difficiles à broyer ont tendance à s'accumuler à l'intérieur de la crépine, ce qui peut finir par bloquer l'appareil. Il est alors nécessaire de procéder au démontage de l'ensemble pour le remettre en état de fonctionnement.This type of device has a number disadvantages: fibrous products such as wipes or periodic towels that are difficult to grind have tendency to accumulate inside the strainer, which may end up blocking the device. It is then necessary to dismantle the assembly to restore it Operating.
L'on connaít également des pompes de dilacération dans lesquelles le système de broyage est intégré à la pompe. Dans un premier cas le système de dilacération est constitué de quelques lames coupantes montées sur le rotor, à l'intérieur de la pompe centrifuge. Cette dernière possède une entrée axiale de diamètre relativement réduit pour fonctionner correctement. Il arrive toutefois que certains déchets solides tels que du papier essuie-mains, des serviettes ou des tampons périodiques jetés dans la cuvette des toilettes restent bloqués à l'entrée de la pompe et s'accrochent au rotor, ce qui finit également par bloquer celui-ci.There are also known to be dilaceration pumps in which the grinding system is integrated with the pump. In a first case the dilaceration system consists of some cutting blades mounted on the rotor, inside centrifugal pump. The latter has an entrance axial of relatively small diameter to work correctly. However, some such as paper towels, towels or periodic tampons thrown into the toilet bowl remain blocked at the pump inlet and cling to the rotor, which also ends up blocking this one.
Dans un autre cas, suivant le brevet DE 4 128 281, le
dispositif de broyage présente une lame et une contre-lame
disposées à l'entrée de la pompe, l'une étant entraínée en
rotation par le rotor de la pompe et l'autre étant fixe sur
le pourtour pour agir à la manière de cisailles.In another case, according to
Le dispositif présente cependant l'inconvénient d'engendrer un bruit de frottement des lames gênant pour l'utilisateur, ainsi que des risques de blocage en cas de pénétration accidentelle d'objets durs.However, the device has the disadvantage of generating a noise of friction of the blades annoying for the user, as well as risks of blockage in case of penetration accidental hard objects.
Afin de résoudre ces problèmes, il convient de définir un broyeur sanitaire dans lequel on évite le bouchage de la pompe, l'accumulation de déchets solides, le blocage du moteur de pompe, tout en réduisant l'émission de bruits lors de l'utilisation. In order to solve these problems, it is necessary to define a sanitary grinder in which the clogging of the pump, the accumulation of solid waste, the blockage of pump motor, while reducing the emission of noise when of use.
A cet effet, la présente invention a pour objet un broyeur sanitaire pour installation de relevage des eaux usées et de déchets solides, du type comportant au moins un canal d'amenée des eaux dans un caisson, un moteur électrique dont l'axe présente à une extrémité une pompe à rotor à pales et des moyens de broyage en regard d'une chambre de dilacération munie d'une ouverture d'entrée, caractérisé en ce que la face avant du rotor est sensiblement plane et comporte une pluralité de passages pour l'eau, disposés sensiblement radialement et débouchant sur la circonférence du rotor, et en ce que chaque passage du rotor se prolonge par un canal délimité par des pales hélicoïdales, ledit rotor étant logé dans le corps de la pompe de manière que sa face avant soit au moins sensiblement dans le plan de l'ouverture du corps de pompe, des organes de dilacération étant disposés en saillie axiale par rapport à ladite face avant.For this purpose, the present invention relates to a crusher sanitary facility for sewage lifting and solid waste, of the type comprising at least one supply of water in a box, an electric motor of which the axis has at one end a rotor blade pump and grinding means facing a chamber of grinding provided with an entrance opening, characterized in that the face before the rotor is substantially flat and has a plurality of water passages arranged substantially radially and opening on the circumference of the rotor, and in that each passage of the rotor is extended by a channel delimited by helical blades, said rotor being housed in the body of the pump so that its front face is at least substantially in the plane of the opening of the body of pump, with the macerating members being arranged to protrude axial with respect to said front face.
Les organes de dilacération sont complétés par une lame coupante circulaire, disposée dans le plan de l'ouverture du corps, et qui définit avec la face avant du rotor l'ouverture d'entrée de la pompe.The organs of dilaceration are completed by a blade circular cutting, arranged in the plane of the opening of the body, and which defines with the front face of the rotor the opening inlet of the pump.
Ainsi, de manière avantageuse, les déchets solides entraínés par le mouvement de l'eau aspirée par la pompe arrivent sur la face avant du rotor où ils subissent une coupe et/ou une dilacération par les organes de dilacération, tout en étant à la fois repoussés du rotor dans un mouvement de turbulences du fait des chocs successifs des organes de dilacération en saillie, et aspirés par le mouvement global de l'eau. Ce mouvement de turbulences est engendré par le rotor de type hélico-centrifuge dont les pales de forme hélicoïdales chassent l'eau à la fois vers la périphérie du rotor, du fait de la force centrifuge, et vers la partie arrière du rotor, du fait de l'inclinaison des pales par rapport à un plan axial. La force centrifuge exercée par le rotor entraíne les résidus vers la lame coupante extérieure. Thus, advantageously, the solid waste entrained by the movement of the water sucked by the pump arrive on the front face of the rotor where they undergo a cut and / or maceration by the organs of grinding, while being both repelled from the rotor in a turbulent motion because of the successive shocks of the grinding elements in protruded, and sucked up by the global movement of water. This turbulence motion is generated by the rotor-type helico-centrifugal with helicoidal blades flush the water both to the periphery of the rotor, centrifugal force, and towards the rear part of the rotor, because of the inclination of the blades with respect to a plane axial. The centrifugal force exerted by the rotor causes the residues to the outer cutting blade.
La partie avant du rotor est donc fermée à l'exception du ou des passages ménagés sur la face avant et qui, de forme allongée droite ou courbe et disposés sensiblement radialement, débouchent donc sur la périphérie de la face avant du rotor. La largeur de ces passages se situe dans une plage de 2 à 15 mm, la largeur des passages étant de préférence constante ou augmentant du centre du rotor vers l'extérieur du rotor.The front part of the rotor is thus closed except for the passages on the front and which, in form elongated straight or curved and arranged substantially radially, therefore lead to the periphery of the face before the rotor. The width of these passages is in a range from 2 to 15 mm, the width of the passages being constant or increasing preference from the center of the rotor towards the outside of the rotor.
Du fait de la largeur limitée des passages, ceux-ci jouent un rôle de filtre dans la mesure où ils bloquent l'entrée de la pompe aux amas de déchets solides trop grands. Ceux-ci ne pouvant entrer que partiellement, glissent alors vers l'extérieur du rotor sous l'effet de la force centrifuge et de l'eau et sont alors soumis à l'action d'une lame circulaire qui sépare les parties bloquées à l'extérieur du rotor de celles qui y sont partiellement introduites.Because of the limited width of the passages, they play a role of filter in that they block the entry of the pump to piles of solid waste too big. These do not can only partially enter, then the outside of the rotor under the effect of centrifugal force and of water and are then subjected to the action of a blade circular that separates the blocked parts outside the rotor of those that are partially introduced.
Les organes de dilacération sont disposés en saillie axiale de 1 à 10 mm sur la face avant du rotor. Ces organes de dilacération sont réalisés dans un matériau dur, résistant à l'usure, tel qu'un métal par exemple, et sont dimensionnés et conformés de manière à couper et/ou lacérer les déchets solides sans les retenir. Les organes de dilacération peuvent être de forme sensiblement conique, droite ou inclinée ou de préférence être plats soit en dents de scie soit en lamelles coupantes, dès lors que la face d'attaque est suffisamment inclinée pour éviter de retenir et d'entraíner en rotation les substances fibreuses.The macerating members are arranged in axial projection from 1 to 10 mm on the front face of the rotor. These bodies are made of a hard material resistant to wear, such as a metal for example, and are dimensioned and shaped to cut and / or lacerate waste solid without holding them back. Macerating organs can be of substantially conical, straight or inclined shape or of preferably be flat either sawtooth or slats when the leading face is sufficiently inclined to avoid retaining and rotate fibrous substances.
Les organes de dilacération peuvent être ménagés sur un insert sur lequel le rotor est surmoulé ou bien ledit insert, tel qu'une plaque métallique, est rapporté sur la face avant du rotor, la plaque métallique étant découpée de manière à laisser les passages du rotor libres lorsqu'elle est apposée sur la face avant dudit rotor. Ces organes de dilacération peuvent être également fixés dans des compartiments ménagés à cet effet sur la face avant du rotor.The macerating members may be arranged on a insert on which the rotor is overmoulded or said insert, such as a metal plate, is attached to the front face of the rotor, the metal plate being cut in such a way as to leave the rotor passages free when affixed on the front face of said rotor. These bodies of dilaceration may also be fixed in compartments this effect on the front face of the rotor.
Comme cité précédemment l'ouverture du corps de pompe est pourvue d'une lame coupante circulaire de diamètre intérieur légèrement supérieur au diamètre extérieur de la face avant du rotor. Ainsi, lors du rejet vers l'extérieur des déchets solides de trop grandes dimensions pour entrer dans les passages définis sur la face avant du rotor, la lame présente à la périphérie du rotor participe au traitement de coupe et de lacération des déchets du fait du mouvement relatif du rotor par rapport à cette lame.As mentioned before the opening of the pump body is equipped with a circular cutting blade of internal diameter slightly greater than the outside diameter of the front face of the rotor. Thus, when discharging waste to the outside solids that are too big to fit into defined passages on the front of the rotor, the blade presents at the periphery of the rotor participates in cutting processing and waste laceration due to the relative movement of rotor relative to this blade.
De manière à améliorer les phénomènes de coupe et/ou lacération, d'auto-nettoyage des passages d'eau et de pompage précédemment décrits, on peut également mettre en place des organes de dilacération sur le fond de la chambre de dilacération en regard de la partie centrale du rotor et/ou sur la périphérie de l'ouverture du corps de pompe.In order to improve the cutting phenomena and / or laceration, self-cleaning of water passages and pumping previously described, it is also possible to set up macerating organs on the bottom of the chamber of misalignment opposite the central part of the rotor and / or on the periphery of the opening of the pump body.
La chambre de dilacération est définie entre la face avant du rotor pourvue des organes de dilacération, la face avant du corps de pompe, un fond et une paroi périphérique. Cette paroi périphérique non fermée est de préférence sensiblement circulaire et présente une forme ramenant les eaux et les solides en mouvement tourbillonnaire vers le centre du rotor. En particulier, ladite paroi périphérique présente une extrémité en forme de bec courbé pointant en direction de l'axe de rotation du rotor.The tear chamber is defined between the front face of the rotor provided with the shearing elements, the front face of the pump body, bottom and peripheral wall. This unclosed peripheral wall is preferably substantially circular and presents a shape bringing back the waters and solids in swirling motion towards the center of the rotor. In particular, said peripheral wall has a bent nose end pointing towards the axis of rotation of the rotor.
Ce bec est disposé de manière adjacente à l'entrée des eaux et des déchets vers la chambre de dilacération, de façon à ramener la direction du flux tourbillonnaire sensiblement parallèle et dans la même direction que le flux entrant dans la chambre de dilacération. This beak is disposed adjacent to the water inlet and waste to the churn chamber, so that bring back the direction of the swirling flow substantially parallel and in the same direction as the incoming flow in the dilaceration chamber.
De préférence, le fond de la chambre de dilacération comporte au moins une protubérance qui est disposée excentrée par rapport à l'axe de rotation du rotor. Cette ou ces protubérances aident au déplacement des solides vers le rotor et les organes de dilacération dans le mouvement tourbillonnaire généré dans la chambre de dilacération.Preferably, the bottom of the grinding chamber comprises at least one protuberance which is disposed off-center by relative to the axis of rotation of the rotor. This or these protuberances help move solids to the rotor and the bodies of misplacement in the movement swirling generated in the dilaceration chamber.
Selon une forme de réalisation préférée de l'invention, le moteur et la pompe ainsi que les organes électriques du broyeur sont enfermés dans un compartiment étanche aux eaux d'un caisson dans lequel il est logé et qui présente une forme sensiblement parallèlépipèdique ou cylindrique. De préférence, ce compartiment étanche est réalisé sous forme d'une cassette emboítable dans le caisson et démontable, ladite cassette étant en particulier adaptable à l'extrémité dudit caisson dont le fond constitue le fond de la chambre de dilacération, la paroi périphérique définissant également la chambre de dilacération. La position de la cassette étant déportée par rapport à l'axe de débranchement de la cuvette, il est ainsi possible d'enlever, sans démontage fastidieux du broyeur, la cassette comportant le moteur, la pompe et les moyens de broyage pour la réparer, en faire l'entretien, voire réaliser un échange standard en cas de défectuosité.According to a preferred embodiment of the invention, the motor and pump as well as the electrical parts of the crusher are enclosed in a watertight compartment of a box in which it is housed and which presents a substantially parallelepipedic or cylindrical shape. Of preferably, this watertight compartment is made in the form of a cassette nestable in the box and removable, said cassette being in particular adaptable to the end said box whose bottom constitutes the bottom of the chamber of the peripheral wall also defining the tearing chamber. The position of the cassette being offset with respect to the axis of disconnection of the bowl, it is thus possible to remove without tedious disassembly of crusher, the cassette comprising the motor, the pump and the means of grinding to repair, maintain, even make a standard exchange in case of defect.
Une partie du caisson située immédiatement derrière la cuvette de WC sert de chambre de réserve permettant de recueillir rapidement les eaux en provenance du WC.Part of the box located immediately behind the WC bowl serves as a reserve chamber allowing quickly collect water from the toilet.
Le canal d'amenée des eaux usées peut être sous forme d'une pipe coudée traversant le caisson et amenant les eaux et les déchets solides en sortie de la cuvette de WC vers l'ouverture d'entrée de la chambre de dilacération. On obtient ainsi que les solides soient immédiatement aspirés et contenus dans la chambre de dilacération, alors que le surplus d'eau ne pouvant être immédiatement contenu dans cette dernière s'écoule vers la chambre de réserve ménagée dans le caisson et faisant office de réservoir tampon. On évite ainsi l'accumulation des déchets solides dans le caisson. On peut également envisager de réaliser le canal d'amenée des eaux par un système de cloisons favorisant l'élimination des bulles d'air avant qu'elles n'atteignent la chambre de dilacération, ce qui permet de diminuer les bruits engendrés. Par ailleurs, la pipe recevant les eaux usées peut être positionner directement sur l'organe de pompage et de broyage.The sewage supply channel may be in the form of a pipe bent through the caisson and bringing water and solid waste coming out of the toilet bowl towards the inlet opening of the dilaceration chamber. We gets so that the solids are immediately sucked up and contained in the dilaceration chamber, while the excess water that can not be immediately contained in the latter flows towards the spare chamber in the box and acting as a buffer tank. We avoids the accumulation of solid waste in the caisson. We can also consider making the channel of water supply by a system of partitions favoring the removal of air bubbles before they reach the chamber of laceration, which makes it possible to reduce the noises generated. Moreover, the pipe receiving wastewater can be positioned directly on the pumping device and grinding.

de l'invention, comporte un caisson 1 recevant les eaux, un
compartiment étanche 2 renfermant les organes électriques E,
ainsi qu'un moteur électrique M disposé verticalement selon
un axe X.As shown in FIGS. 1, 2 or 3, the grinder
sanitary facility for sewage lifting and
solid waste, according to a non-limiting embodiment
of the invention, comprises a
Ce moteur M entraíne à son extrémité inférieure un rotor 5 à
pales 6 d'une pompe de relevage. Le rotor 5 est muni de
moyens de dilacération disposés en regard d'une chambre de
dilacération 3 définie entre le fond du caisson 1 et une
paroi périphérique 4 munie d'une ouverture d'entrée 4a.This motor M drives at its lower end a
Comme représenté sur les figures 1, 4, 5 et 6, la face avant
5a du rotor 5 est sensiblement plane et comporte une
pluralité de passages 7 pour l'eau, disposés sensiblement
radialement et débouchant sur la périphérie du rotor 5. A
chaque passage 7 correspond une pale hélicoïdale 6 du rotor
5.As shown in FIGS. 1, 4, 5 and 6, the
Le rotor 5 est logé dans le corps 8 de la pompe de manière
que sa face avant 5a soit sensiblement dans le plan de
l'ouverture du corps de pompe 8 (cf la figure 1) ou en légère
saillie par rapport à ce plan (cf la figure 5). L'ouverture
du corps de pompe 8 de diamètre intérieur légèrement
supérieur au diamètre extérieur de la partie avant 5a du
rotor 5 est, de préférence, matérialisée par une lame
coupante circulaire 11.The
Les moyens de dilacération sont formés par des organes 9, de
forme conique inclinée aux figures 4 et 5, disposés en
saillie axiale par rapport à ladite face avant 5a.The means of dilaceration are formed by
Sur les figures 6 et 7 est représentée une variante de
réalisation d'organes de dilacération 9. Ceux-ci sont ménagés
sur un insert métallique 10 rapporté ensuite sur la face
avant 5a du rotor 5 ou le rotor peut être surmoulé sur ledit
insert 10. L'insert est réalisé en étoile dont les branches
10' viennent se loger entre les passages 7 pour l'eau.
L'extrémité de chaque branche 10' est découpée en pointe et
cette pointe est repliée pour former un organe de
dilacération 9. Lorsqu'on met en place l'insert 10 sur la
face avant 5a du rotor 5, -chaque pointe 9 est disposée à
proximité d'un passage 7.Figures 6 and 7 show a variant of
realization of bodies of
Le moteur M et la pompe ainsi que les organes électriques E
sont logés dans un compartiment étanche 2 réalisé sous forme
de cassette (cf la figure 1) dans le fond de laquelle est
logé le corps de pompe 8 avec le rotor 5. Cette cassette 2
est mise en place dans le caisson 1 de telle sorte que le
rotor 5 soit en regard du fond du caisson 1 au niveau de la
chambre de dilacération 3 définie par la paroi périphérique
4.The motor M and the pump as well as the electric members E
are housed in a sealed
Cette paroi périphérique 4 est sensiblement circulaire et
délimite donc la chambre de dilacération 3, contenant le
mouvement tourbillonnaire (selon la flèche C) des eaux et des
solides entrant dans ladite chambre 3 (cf la figure 3).This
La paroi périphérique 4 présente une extrémité en forme de
bec courbé 4b pointant sensiblement en direction de l'axe de
rotation X du rotor 5. Cette forme particulière de
l'extrémité de la paroi périphérique favorise l'entrée des
déchets dans la chambre de dilacération 3 mais évite
également la sortie de ces déchets, la redirection des eaux
induites par ce bec 4b tendant à ramener les déchets vers le
centre de la chambre de dilacération 3.The
Afin de favoriser également le déplacement des déchets dans
la chambre 3, le fond du caisson 1 peut comporter dans ladite
chambre de dilacération 3 des parties en relief agissant sur
le mouvement des déchets, de façon à améliorer le processus
de dilacération. On peut par exemple utiliser deux
protubérances, par exemple coniques, 12, 13 excentrées par
rapport à l'axe de rotation X du rotor 5. L'une des
protubérances 12 se situe à proximité dudit axe X du rotor
tandis que l'autre protubérance 13 est disposée sensiblement
à la jonction des flux entrant et tourbillonnant dans la
chambre de dilacération 3.In order to promote also the movement of waste in
the
La cassette 2 étant positionnée de préférence à une extrémité
du caisson 1, l'évacuation des eaux usées et des déchets
solides en sortie d'une cuvette des toilettes par exemple
n'est pas en regard de la chambre de dilacération 3. Pour
éviter que les solides flottants ne s'accumulent dans la
partie tampon du caisson, on met alors en place un canal
d'amenée des eaux, par exemple une canalisation coudée 14,
qui amène les eaux et les déchets solides en sortie d'une
évacuation vers l'ouverture 4a de la chambre de dilacération
3.The
De préférence, l'extrémité de la paroi 4 présente aussi un
bec 4c en direction sensiblement opposée à celle du bec 4b de
telle sorte qu'en sortie de la canalisation 14, ce bec 4c et
le bec 4 b guident les déchets solides vers l'entrée 4a de la
chambre de dilacération 3. Le bec 4c permet également de
définir une zone de non turbulence pour le captage de la
hauteur d'eau détectée par un pressostat.Preferably, the end of the
Les déchets solides entraínés par le mouvement de l'eau
aspirée par la pompe arrivent sur la face avant du rotor 5 où
ils subissent une coupe et/ou une dilacération par les
organes de dilacération 9, tout en étant à la fois repoussés
du rotor 5 dans un mouvement de turbulences du fait des chocs
successifs des organes de dilacération 9 en saillie, et
aspirés par le mouvement global de l'eau. Ce mouvement de
turbulences est engendré par le rotor 5 du type hélico-centrifuge.
Les pales 6 de forme hélicoïdale chassent l'eau à
la fois vers la périphérie du rotor 5 du fait de la force
centrifuge et vers la partie arrière du rotor 5 du fait de
l'inclinaison des pales 6 par rapport à un plan axial.Solid wastes driven by the movement of water
sucked by the pump arrive on the front face of the
La cassette 2 comporte une sortie 15 du corps de pompe 8
raccordable par le collecteur de sortie 15 à une conduite
d'évacuation 16. Cette conduite d'évacuation 16 est prolongée
de préférence par un clapet anti-retour solidaire de la
conduite de refoulement.The
De préférence, le caisson 1 comporte des branchements 20 pour
d'autres arrivées d'eau et de déchets de telle sorte qu'il
est raccordable à d'autres installations de relevage d'eaux
usées telles que lavabo, bidet, douche, etc.Preferably, the
Pour favoriser le refroidissement du moteur en cas d'utilisation intensive, on peut prévoir un système de capot enserrant la partie supérieure du moteur, munie d'ailettes, et canalisant le flux d'air.To promote engine cooling in case of intensive use, it can provide a hood system enclosing the upper part of the engine, provided with fins, and channeling the airflow.
