Description

ENSE BLE POUR LE NETTOYAGE D'UN BASSIN DE CLARIFICATION ENSE BLE FOR CLEANING A CLARIFICATION BASIN
DESCRIPTIONDESCRIPTION
L'invention concerne un ensemble pour le nettoyage d'un bassin de clarification pour stations d'épuration d'eau potable ou d'eaux usées domestiques, industrielles ou agroalimentaires du type délimité par un mur et comportant essentiellement une goulotte formée par ledit mur, un fond et une lame versante ; une cloison siphoïde reliée à la base de ladite lame au moyen de traverses ; un pont racleur associé à un motoréducteur et à une roue d'entraînement.The invention relates to an assembly for cleaning a clarification basin for stations for purifying drinking water or domestic, industrial or food-processing wastewater of the type delimited by a wall and essentially comprising a chute formed by said wall, a bottom and a pouring blade; a siphon partition connected to the base of said blade by means of crosspieces; a scraper bridge associated with a gear motor and a drive wheel.
Les ensembles connus du genre en question, entraînés par le pont racleur, ne nettoient qu'une partie de la goulotte et non l'intégralité de celle-ci. En outre, lesdits ensembles ne nettoient pas l'intérieur de la zone délimitée par la lame versante, les traverses et la cloison siphoïde.Known assemblies of the genus in question, driven by the scraper bridge, only clean part of the chute and not all of it. In addition, said assemblies do not clean the interior of the area delimited by the pouring blade, the crosspieces and the siphon partition.
L'invention vise donc à réaliser un ensemble qui nettoie d'une part l'intégralité de la goulotte et d'autre part, en addition, l'intégralité de la zone susmentionnée. Elle concerne à cet effet un ensemble qui se caractérise essentiellement en ce qu'il comporte, en combinaison, un premier jeu de brosses adaptées pour nettoyer le fond de la goulotte et un deuxième jeu de brosses adaptées pour nettoyer les bords verticaux de ladite goulotte ; en ce que le premier jeu de brosses est solidaire d'un des côtés verticaux d'un premier parallélogramme articulé dont l'autre côté vertical est solidaire d'un mât vertical principal relié au pont racleur et en ce que le deuxième jeu de brosses est solidaire d'un des côtés verticaux d'un deuxième parallélogramme articulé dont l'autre côté vertical est relié au côté vertical, du premier parallélogramme articulé, porteur du premier jeu de brosses. L'ensemble en question se caractérise également en ce qu'il comporte, en addition, un troisième jeu de brosses adaptées pour nettoyer, pour la première, le dessus des traverses et, pour les deux autres, les parois verticales en regard respectivement de la lame versante et de la cloison siphoïde et en ce que ledit troisième jeu de brosses est également solidaire du mât principal.The invention therefore aims to achieve an assembly which cleans on the one hand the whole of the chute and on the other hand, in addition, the entire area mentioned above. To this end, it relates to an assembly which is essentially characterized in that it comprises, in combination, a first set of brushes suitable for cleaning the bottom of the chute and a second set of brushes suitable for cleaning the vertical edges of said chute; in that the first set of brushes is integral with one of the vertical sides of a first articulated parallelogram of which the other vertical side is integral with a main vertical mast connected to the scraper bridge and in that the second set of brushes is secured to one of the vertical sides of a second articulated parallelogram, the other vertical side of which is connected to the vertical side, of the first articulated parallelogram, carrying the first set of brushes. The assembly in question is also characterized in that it comprises, in addition, a third set of brushes suitable for cleaning, for the first, the top of the crosspieces and, for the other two, the vertical walls opposite respectively of the pouring blade and the siphon wall and in that said third set of brushes is also integral with the main mast.

According to an alternative embodiment (Figure 3) of the sub-assembly comprising the brushes (8), two brushes (8) are connected by an arm (61) itself connected to the axis (36). They also include pins (33) associated with return springs. According to another embodiment (FIG. 6) of the articulated parallelogram sub-assembly (12, 13) and brushes cleaning the bottom of the chute (2), said sub-assembly comprises two rotary brushes (63) with inclined fibers (approximately 30 °) with respect to their supports (72) at two opposite angles so as to create a resistance causing their rotation (in two opposite directions of rotation) when they move in the chute (2), a flange (64) for fixing said sub- together with the mast (14), two arms (65) completing the parallelogram (12,13), a jack (66) capable of adjusting the pressing pressure of said brushes on the bottom of said chute, a jack (67) suitable for make up for the narrowing of said chute by acting on the rotation of the arm (36) during the movement of said sub-assembly, a support (68) of said brushes adjustable by means of the clamping nut (69) to adjust the cleaning width to the maximum width of said chute, at least one bearing (70) supporting the pins (71) connected to the supports (72) of said brushes (63). As before (Figure 2), the second set of brushes (9) is integral with one of the vertical sides (17) of the second articulated parallelogram whose other vertical side (41) is connected to the vertical side (12), of the first articulated parallelogram, carrying the first set of brushes (63).
Une poignée (62) est fixée au mât (14) pour positionner les brosses (8,63) dans la goulotte (2). Les parallélogrammes articulés permettent le maintien vertical des axes (36,28,46) porteurs des brosses (8,9,18,19,63) donc l'appui horizontal des brosses (8,18,63) et vertical des brosses (9,19) sur les parois contre lesquelles elles s'appuient. Le deuxième parallélogramme articulé, ayant pour côté (41), peut comporter une butée réglable limitant vers le bas le déplacement du côté opposé (17) de manière à permettre le remplacement des deux roulettes (26) par une seule roulette centrale qui de ce fait ne peut pas chuter dans l'ouverture d'évacuation (27). En outre, les roulements (70) pourraient être déplacés sur les supports (72) des brosses (63) afin d'être remplacés, en partie haute des axes (71), par un collier adapté pour régler l'inclinaison des brosses selon deux axes longitudinaux et transversaux au moyen de tiges filetées articulées par une chape ou une rotule.A handle (62) is fixed to the mast (14) to position the brushes (8,63) in the chute (2). The articulated parallelograms allow the vertical support of the axes (36,28,46) carrying the brushes (8,9,18,19,63) therefore the horizontal support of the brushes (8,18,63) and vertical of the brushes (9 , 19) on the walls against which they rest. The second articulated parallelogram, having for side (41), may include an adjustable stop limiting downward movement of the opposite side (17) so as to allow the replacement of the two rollers (26) by a single central roller which therefore cannot fall into the discharge opening (27). In addition, the bearings (70) could be moved on the supports (72) of the brushes (63) in order to be replaced, in the upper part of the axes (71), by a collar adapted to adjust the inclination of the brushes in two longitudinal and transverse axes by means of threaded rods articulated by a yoke or a ball joint.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés pour lesquels on pourra prévoir d'autres variantes, en particulier dans :Of course, the invention is not limited to the embodiments described and shown for which other variants can be provided, in particular in:
- les types de roulements, de brides de serrage et de brosses ; - les conceptions et les dimensions des divers supports de brosses, des bras de liaison et des parallélogrammes articulés ;- types of bearings, clamps and brushes; - the designs and dimensions of the various brush holders, link arms and articulated parallelograms;
- les types de bassins de clarification ; et l'étendre à d'autres applications. - the types of clarification tanks; and extend it to other applications.
