DESCRIPTION DÉTAILLÉE DETAILED DESCRIPTION
Comme mentionné ci-dessus, l'invention a pour objet un dispositif 1 d'agitation de fluide, en particulier de liquide, plus particulièrement adapté à l'agitation de peinture stockée à l'intérieur d'un contenant 20, tel qu'un pot, fermé par un couvercle 21 , le dispositif 1 d'agitation faisant saillie au moins partiellement du couvercle 21 . As mentioned above, the subject of the invention is a device 1 for stirring fluid, in particular liquid, more particularly adapted to the stirring of paint stored inside a container 20, such as a pot, closed by a cover 21, the stirring device 1 projecting at least partially from the cover 21.
Ce dispositif 1 d'agitation comprend un arbre 2 d'agitation apte à être entraîné en rotation, en particulier à tourner sur lui-même, un élément 3 de brassage et des moyens 4 de liaison entre l'élément 3 de brassage et l'arbre 2 d'agitation, l'arbre 2 d'agitation étant positionnable depuis son extrémité inférieure 5 en direction de son extrémité supérieure 6 verticalement, en configuration d'utilisation, c'est-à-dire généralement perpendiculairement à la face formant fond du contenant 20. This stirring device 1 comprises a stirring shaft 2 adapted to be rotated, in particular to rotate on itself, a stirring element 3 and connecting means 4 between the stirring element 3 and the stirring element 3. stirring shaft 2, the stirring shaft 2 being positionable from its lower end 5 towards its upper end 6 vertically, in the configuration of use, that is to say generally perpendicular to the bottom face of the containing 20.
L'entraînement en rotation de l'arbre 2 d'agitation peut s'opérer de manière diverse et variée selon l'environnement dans lequel le dispositif 1 d'agitation est disposé. Ainsi, l'arbre 2 d'agitation peut être couplé à une tête d'entraînement équipant une armoire d'agitation de pots de peinture. Cet arbre 2 d'agitation peut encore être couplé à l'arbre moteur d'un outil, tel qu'une perceuse, ou autre. Lorsque cet arbre 2 d'agitation équipe le couvercle 21 d'un contenant 20, comme illustré à la figure 1 , l'arbre 2 d'agitation traverse une ouverture traversante du couvercle, et l'extrémité supérieure de l'arbre 2 d'agitation est disposée au-dessus du couvercle, pour venir en prise avec des moyens d'entraînement en rotation dudit arbre, tandis que l'extrémité 5 inférieure de l'arbre 2 d'agitation, l'élément 3 de brassage et les moyens 4 de liaison entre l'élément 3 de brassage et l'arbre 2 d'agitation sont disposés au-dessous du couvercle 21 , à l'intérieur du contenant 20. The rotational drive of the stirring shaft 2 can operate in a diverse and varied manner depending on the environment in which the stirring device 1 is disposed. Thus, the stirring shaft 2 can be coupled to a drive head equipping a stirrer of pots of paint. This shaking shaft 2 can still be coupled to the drive shaft of a tool, such as a drill, or other. When this stirring shaft 2 equips the lid 21 of a container 20, as illustrated in FIG. 1, the stirring shaft 2 passes through an opening through the cover, and the upper end of the stirring shaft 2 is disposed above the cover, to engage means for driving in rotation of said shaft, while the lower end of the agitating shaft 2, stirring element 3 and connecting means 4 between stirring element 3 and stirring shaft 2 are arranged below cover 21, inside container 20.
L'élément 3 de brassage comprend un tronçon 7 d'anneau circulaire entourant partiellement l'arbre 2 d'agitation. Ce tronçon d'anneau 7 est en position verticale de l'arbre 2 d'agitation correspondant à la configuration d'utilisation disposé dans un plan incliné par rapport à l'arbre 2 d'agitation. En d'autres termes, le plan circonférentiel du tronçon d'anneau 7 passant par les extrémités inférieure 8 et supérieure 9 du tronçon 7 forme avec un plan perpendiculaire à l'arbre 2 d'agitation un angle A généralement compris entre 5° et 45°, de préférence voisin de 15°. Ce tronçon 7 d'anneau affecte une forme générale de tronçon de tore évidé centralement, la surface du tore étant ajourée. Ce tronçon 7 d'anneau se développe entre son extrémité inférieure 8 et son extrémité supérieure 9 sur au moins 90°, de préférence 180°. De préférence, le secteur angulaire formé par le tronçon 7 d'anneau est compris dans la plage 90° - 270°. Dans les exemples représentés, ce tronçon 7 d'anneau forme donc à la manière d'une cage annulaire un tronçon de tore creux ou d'anneau creux de section circulaire munie d'ouvertures 1 1 de communication de sa cavité 10 avec l'extérieur. En particulier, dans l'exemple représenté, le tronçon d'anneau 7 est formé de deux tronçons de cercle 16 parallèles concentriques, entourant partiellement l'arbre 2 d'agitation, ces deux tronçons de cercle 16, de rayons différents, étant reliés entre eux par des demi-anneaux 17 s'étendant chacun dans un plan radial à l'arbre 2 d'agitation. Les demi-anneaux 17 sont organisés en deux séries 171 , 172, s'étendant respectivement l'une 171 , au-dessus du plan passant par les deux tronçons de cercle 16, l'autre 172, au-dessous du plan passant par les deux tronçons de cercle 16, en configuration d'utilisation de l'arbre 2 d'agitation. Les demi-anneaux 17 sont décalés axialement le long des tronçons de cercle 16 d'une série de demi-anneaux à l'autre série de demi- anneaux. Les demi-anneaux 17 d'une série sont, dans les exemples représentés, écartés l'un de l'autre d'un pas constant. Chaque demi-anneau 17 intermédiaire d'une série, c'est-à-dire formé par un demi-anneau autre que les demi-anneaux d'extrémité de la série est disposé en regard de l'espace laissé libre entre deux demi-anneaux successifs de l'autre série de demi-anneaux. Ainsi, les demi- anneaux 17 s'étendent depuis l'extrémité inférieure 8 du tronçon 7 d'anneau en direction de l'extrémité supérieure 9 du tronçon 7 d'anneau, alternativement au-dessous et au-dessus du plan passant par les tronçons de cercles 16. The stirring element 3 comprises a segment 7 of circular ring partially surrounding the stirring shaft 2. This ring segment 7 is in the vertical position of the stirring shaft 2 corresponding to the use configuration disposed in a plane inclined with respect to the stirring shaft 2. In other words, the circumferential plane of the ring segment 7 passing through the lower 8 and upper 9 ends of the section 7 forms with a plane perpendicular to the shaking shaft 2 an angle A generally between 5 ° and 45 °. °, preferably close to 15 °. This ring segment 7 has a general shape of centrally hollowed core section, the surface of the core being perforated. This ring segment 7 develops between its lower end 8 and its upper end 9 over at least 90 °, preferably 180 °. Preferably, the angular sector formed by the ring segment 7 is in the range 90 ° - 270 °. In the examples shown, this ring segment 7 thus forms, in the manner of an annular cage, a section of hollow torus or hollow ring of circular section provided with openings 1 1 for communicating its cavity 10 with the outside. . In particular, in the example shown, the ring segment 7 is formed of two concentric parallel circle sections 16, partially surrounding the stirring shaft 2, these two circle sections 16, of different radii, being connected between they by half-rings 17 each extending in a radial plane to the shaft 2 stirring. The half-rings 17 are organized in two series 171, 172, respectively extending one 171, above the plane passing through the two circle sections 16, the other 172, below the plane passing through the two sections of circle 16, in use configuration of the stirring tree 2. The half-rings 17 are axially offset along the circle sections 16 of a series of half-rings to the other series of half-rings. The half-rings 17 of a series are, in the examples shown, spaced apart from each other by a constant pitch. Each half-ring 17 intermediate a series, that is to say formed by a half-ring other than the end half-rings of the series is arranged opposite the space left free between two half successive rings of the other series of half-rings. Thus, the half-rings 17 extend from the lower end 8 of the ring segment 7 towards the upper end 9 of the ring segment 7, alternately below and above the plane passing through them. sections of circles 16.
Cette disposition particulière confère à l'ensemble des demi-anneaux une forme proche d'une forme spiralée, sans présenter les difficultés de démoulage d'une spirale. Il en résulte la possibilité de réaliser d'une seule pièce l'élément de brassage 3, les moyens 4 de liaison entre l'élément 3 de brassage et l'arbre 2 d'agitation, et au moins une partie de l'arbre 2 d'agitation. This particular arrangement gives all the half-rings a shape close to a spiral shape, without the difficulties of demolding a spiral. This results in the possibility of producing in one piece the stirring element 3, the connecting means 4 between the stirring element 3 and the stirring shaft 2, and at least a portion of the shaft 2 stirring.
Les ouvertures 1 1 de communication avec l'extérieur du tronçon d'anneau 7 sont donc formées par l'espace laissé libre entre deux demi-anneaux successifs d'une série d'anneaux. The openings 1 1 of communication with the outside of the ring segment 7 are formed by the space left free between two successive half-rings of a series of rings.
Les moyens 4 de liaison entre l'arbre 2 d'agitation et l'élément 3 de brassage comprennent au moins un bras 12 radial à l'arbre 2 d'agitation disposé entre l'extrémité inférieure 5 de l'arbre 2 d'agitation et l'extrémité inférieure 8 de l'élément 3 de brassage. Ce bras 12 radial relie les extrémités inférieures de l'arbre d'agitation et de l'élément de brassage entre elles. Ce bras 12 radial, apte à faire office de racleur et appelé bras 12 de liaison inférieur s'étend au moins partiellement dans un plan perpendiculaire à l'arbre 2 d'agitation. Cette disposition permet en effet de traiter la matière accumulée par sédimentation au fond du contenant et d'éviter une telle accumulation de matière qui nuirait à l'homogénéité du mélange. The connecting means 4 between the stirring shaft 2 and the stirring element 3 comprise at least one radial arm 12 to the stirring shaft 2 disposed between the lower end 5 of the stirring shaft 2. and the lower end 8 of the stirring element 3. This radial arm 12 connects the lower ends of the stirring shaft and the stirring element between them. This radial arm 12, able to act as scraper and called lower link arm 12 extends at least partially in a plane perpendicular to the shaft 2 stirring. This arrangement makes it possible to treat the accumulated matter by sedimentation in the bottom of the containing and avoiding such an accumulation of material that would harm the homogeneity of the mixture.
Dans les exemples représentés, le bras 12 de liaison inférieur affecte la forme d'une lame 120 présentant, pris par rapport au sens de rotation de l'arbre 2 d'agitation, un bord longitudinal avant ou d'attaque 121 , un bord longitudinal arrière 122 et deux bords transversaux. L'un des bords transversaux de la lame constitue le bord de liaison de la lame à l'extrémité inférieure de l'arbre 2 d'agitation. L'extrémité inférieure 8 du tronçon d'anneau 7 est quant à elle raccordée à la lame 120 constitutive du bras 12 de liaison inférieur, au niveau du bord longitudinal arrière ou bord de fuite longitudinal 122 de ladite lame 120. In the examples shown, the lower link arm 12 has the shape of a blade 120 having, with respect to the direction of rotation of the stirring shaft 2, a longitudinal front or leading edge 121, a longitudinal edge rear 122 and two transverse edges. One of the transverse edges of the blade constitutes the connecting edge of the blade at the lower end of the shaking shaft 2. The lower end 8 of the ring segment 7 is in turn connected to the blade 120 constituting the lower link arm 12, at the longitudinal rear edge or longitudinal trailing edge 122 of said blade 120.
La lame 120 s'étend ainsi devant l'extrémité inférieure 8 du tronçon 7 d'anneau pris par rapport au sens de rotation de l'arbre 2 d'agitation. Cette lame 120 s'étend jusqu'au bord périphérique externe du tronçon 7 d'anneau. Dans l'exemple représenté, les bords longitudinaux avant 121 et arrière 122 de la lame 120 sont reliés entre eux par deux faces formant respectivement les faces du dessus 123 et du dessous 124 de la lame 120, en configuration d'utilisation de l'arbre 2 d'agitation. The blade 120 thus extends in front of the lower end 8 of the ring segment 7 taken with respect to the direction of rotation of the stirring shaft 2. This blade 120 extends to the outer peripheral edge of the segment 7 ring. In the example shown, the longitudinal front edges 121 and rear 122 of the blade 120 are interconnected by two faces respectively forming the top faces 123 and bottom 124 of the blade 120, in the configuration of use of the shaft 2 stirring.
Le bord longitudinal avant 121 de la lame 120 s'étend dans un plan perpendiculaire à l'arbre 2 d'agitation, et la face du dessus 123 de la lame 120 forme une surface inclinée, à pente descendante depuis le bord longitudinal arrière 122 vers le bord longitudinal avant 121 de la lame 120. The forward longitudinal edge 121 of the blade 120 extends in a plane perpendicular to the shaking shaft 2, and the top face 123 of the blade 120 forms an inclined surface, downwardly sloping from the trailing longitudinal edge 122 to the longitudinal front edge 121 of the blade 120.
En outre, dans l'exemple représenté, la face du dessus 123 de la lame 120 constitutive du bras 12 de liaison inférieur est concave. En variante, celle-ci aurait pu être plane. Généralement, les faces du dessous et du dessus de la lame sont parallèles entre elles. In addition, in the example shown, the top face 123 of the blade 120 constituting the lower link arm 12 is concave. Alternatively, it could have been flat. Generally, the undersides and the top of the blade are parallel to each other.
Cette configuration inclinée de la lame facilite le soulèvement de matière et son guidage vers le tronçon d'anneau 7. This inclined configuration of the blade facilitates the lifting of material and its guidance towards the ring section 7.
Pour parfaire ce guidage, l'extrémité inférieure 8 du tronçon d'anneau 7 présente, dans sa zone de raccordement au bras 12 de liaison inférieur, un tronçon de gouttière 15 formant rampe. Pour renforcer la résistance mécanique du dispositif et améliorer la qualité du mélange en terme d'homogénéité, les moyens 4 de liaison entre l'arbre 2 d'agitation et l'élément 3 de brassage comprennent, en sus du bras 12 de liaison inférieur, au moins un bras supplémentaire radial à l'arbre d'agitation. To perfect this guidance, the lower end 8 of the ring segment 7 has, in its zone of connection to the lower link arm 12, a gutter section 15 forming a ramp. To strengthen the mechanical strength of the device and improve the quality of the mixture in terms of homogeneity, the connecting means 4 between the stirring shaft 2 and the stirring element 3 comprise, in addition to the lower link arm 12, at least one additional arm radial to the stirring shaft.
Le ou au moins l'un des bras supplémentaires est un bras 14 radial dit supérieur. Ce bras radial supérieur est disposé entre l'extrémité supérieure 9 du tronçon d'anneau 7 et l'arbre 2 d'agitation. The or at least one of the additional arms is a radial arm 14 said upper. This upper radial arm is disposed between the upper end 9 of the ring segment 7 and the stirring shaft 2.
Dans l'exemple représenté, deux bras supplémentaires, respectivement représentés en 13 et 14 sont prévus. L'un des bras, représenté en 14 aux figures affecte la forme d'une lame 140 présentant, pris par rapport au sens de rotation de l'arbre 2 d'agitation, un bord longitudinal avant 141 et un bord longitudinal arrière 142. Ces bords longitudinaux avant 141 et arrière 142 sont reliés entre eux par deux faces formant respectivement les faces du dessus 143 et du dessous 144 de la lame 140, en configuration d'utilisation de l'arbre d'agitation, et la face du dessus 143 de la lame 140 forme une surface inclinée à pente descendante depuis le bord longitudinal arrière vers le bord longitudinal avant 141 . In the example shown, two additional arms, respectively represented at 13 and 14 are provided. One of the arms, shown at 14 in the figures has the shape of a blade 140 having, taken with respect to the direction of rotation of the shaking shaft 2, a longitudinal front edge 141 and a rear longitudinal edge 142. front longitudinal edges 141 and rear 142 are interconnected by two faces respectively forming the top faces 143 and bottom 144 of the blade 140, in the use configuration of the stirring shaft, and the top face 143 of the blade 140 forms a slope inclined surface from the rear longitudinal edge to the front longitudinal edge 141.
Le bras radial représenté en 13 aux figures affecte également la forme d'une lame 130 présentant, pris par rapport au sens de rotation de l'arbre d'agitation, un bord longitudinal avant ou d'attaque 131 et un bord longitudinal arrière 132. Lesdits bords longitudinaux avant 131 et arrière 132 sont reliés entre eux par deux faces formant respectivement les faces du dessus 133 et du dessous 134 de la lame 130 en configuration d'utilisation de l'arbre 2 d'agitation, et la face du dessus 133 de la lame forme une surface inclinée à pente descendante depuis le bord longitudinal arrière 132 vers le bord longitudinal avant 131 de la lame 130. The radial arm shown at 13 in the figures also affects the shape of a blade 130 having, taken with respect to the direction of rotation of the stirring shaft, a longitudinal front or leading edge 131 and a rear longitudinal edge 132. Said longitudinal front edges 131 and 132 are connected to each other by two faces respectively forming the top 133 and bottom 134 faces of the blade 130 in the use configuration of the stirring shaft 2, and the top face 133 of the blade forms an inclined surface with a downward slope from the rear longitudinal edge 132 to the front longitudinal edge 131 of the blade 130.
Ce bras radial 13 supplémentaire s'étend ici à équidistance des bras inférieur 12 et supérieur 14. Les bras 13 et 14 supplémentaires s'étendent au moins partiellement dans le plan moyen ou circonférentiel du tronçon d'anneau 7 passant par les extrémités inférieure et supérieure dudit tronçon. La face du dessus des lames constitutives des bras supplémentaires peut être plane, c'est-à-dire rectiligne, ou concave. Généralement, les faces du dessous et du dessus des lames sont parallèles entre elles. Le fonctionnement d'un tel dispositif 1 d'agitation est similaire à un dispositif d'agitation classique. Pour permettre une agitation du contenu d'un contenant à l'aide d'un tel dispositif d'agitation, il suffit d'introduire le dispositif d'agitation dans le contenant, idéalement jusqu'à ce que l'extrémité inférieure de l'arbre 2 d'agitation repose en appui contre le fond du contenant, comme illustré à la figure 1 , puis d'entraîner en rotation ledit arbre 2 d'agitation, l'extrémité inférieure du tronçon d'anneau étant l'extrémité menante. This additional radial arm 13 extends here at the equidistance of the lower arm 12 and upper arm 14. The additional arms 13 and 14 extend at least partially in the middle or circumferential plane of the ring segment 7 passing through the lower and upper ends. said section. The top face of the constituent blades of the additional arms may be flat, that is to say rectilinear, or concave. Generally, the faces of the underside and the top of the blades are parallel to each other. The operation of such a stirring device 1 is similar to a conventional stirring device. To allow stirring of the contents of a container with the aid of such a stirring device, it is sufficient to introduce the stirring device into the container, ideally until the lower end of the agitating shaft 2 rests against the bottom of the container, as shown in Figure 1, and then rotate said stirring shaft 2, the lower end of the ring section being the leading end.
Pour éviter une usure prématurée de l'extrémité inférieure 5 de l'arbre 2 d'agitation et du fond du contenant 20, cette extrémité inférieure 5 est de préférence sphérique, comme illustré aux figures. To avoid premature wear of the lower end 5 of the stirring shaft 2 and the bottom of the container 20, this lower end 5 is preferably spherical, as shown in the figures.
