Abstract
Description
La présente invention concerne des enceintes auto-nettoyantes pour poudrage électrostatique ou non électrostatique pour peinture ou autre produit.The present invention relates to self-cleaning enclosures for electrostatic or non-electrostatic powdering for paint or other product.
Les enceintes connues sur le Marché comportent toutes des parois rigides diélectriques ou non diélectriques; la poudre en suspension dans ces enceintes se dépose et adhère aux parois par effet électrostatique ou pour toutes autres raisons, par exemple: température ambiante trop élevée ou trop humide. Il n'est pas rare de constater des dépôts de plusieurs millimètres de poudre; ceci a pour conséquence: Une perte de poudre considérable augmentant ainsi le cout de production, Un nettoyage long et difficile interdisant dans la plupart des cas, I'emploi du poudrage électrostatique ou non électrostatique.The enclosures known on the market all have rigid dielectric or non-dielectric walls; the powder in suspension in these enclosures is deposited and adheres to the walls by electrostatic effect or for any other reason, for example: room temperature too high or too humid. It is not uncommon to find deposits of several millimeters of powder; this results in: A considerable loss of powder thus increasing the production cost, A long and difficult cleaning prohibiting in most cases the use of electrostatic or non-electrostatic powdering.
Le dispositif suivant l'invention permet d'éviter tous ces inconvénients.The device according to the invention makes it possible to avoid all of these drawbacks.
Dans celui-ci, en effet, il est possible, par l'action des membranes souples, d'effectuer un poudrage dans une enceinte sans que la poudre se dépose sur les parois.In this one, in fact, it is possible, by the action of flexible membranes, to carry out dusting in an enclosure without the powder being deposited on the walls.
Le dispositif, objet de l'invention, comporte des membranes souples diélectriques ou non diélectriques constituant elles-mêmes une enceinte en revêtant totalement ou partiellement, les surfaces intérieures d'une enceinte à parois rigides.The device, object of the invention, comprises flexible dielectric or non-dielectric membranes themselves constituting an enclosure by completely or partially coating the interior surfaces of an enclosure with rigid walls.
Ces membranes sont agitées en permanence ou par intermittence, pour éviter que la poudre n'adhère aux parois.These membranes are continuously or intermittently agitated to prevent the powder from sticking to the walls.
Les enceintes suivant ce nouveau procédé peuvent être équipées d'un système d'aspiration destiné à maintenir la poudre en suspension.The chambers according to this new process can be equipped with a suction system intended to keep the powder in suspension.
Les 4 formes de réalisation annexées illustrent, à titre d'exemple non limitatif, les modes de réalisation du dispositif.The 4 appended embodiments illustrate, by way of nonlimiting example, the embodiments of the device.
PL I - Fig 1 L'enceinte est constituée d'un cadre (1) supportant les membranes (2) et (3) reliées à leurs parties hautes (4) et (5) à des agitateurs (6) et (7): la poudre en suspension dans l'enceinte diffusée par l'appareil (8) est repoussée vers l'axe longitudinal de l'enceinte co-lncidant avec la trajectoire de la pièce (9) à revêtir ; une partie de la poudre se dépose sur la pièce (9), L'autre partie descend naturellement par gravité et peut être récupérée par différents systèmes au fond (10) de l'en- ceinte.PL I - Fig 1 The enclosure consists of a frame (1) supporting the membranes (2) and (3) connected to their upper parts (4) and (5) to agitators (6) and (7): the powder in suspension in the enclosure diffused by the device (8) is pushed towards the longitudinal axis of the enclosure coinciding with the trajectory of the part (9) to be coated; part of the powder is deposited on the part (9), the other part descends naturally by gravity and can be recovered by different systems at the bottom (10) of the enclosure.
PL 2 - Fig 2 L'enceinte est constituée d'un ensemble rigide (11) revêtu sur les faces intérieures de deux membranes (12) (13) reliées à l'ensemble rigide suivant les pointillés (14) et (15), deux ventilations (16) et (17) fixées aux parois rigides créent des courants d'air entre l'ensemble rigide et les membranes souples (12) et (13).PL 2 - Fig 2 The enclosure consists of a rigid assembly (11) coated on the inner faces with two membranes (12) (13) connected to the rigid assembly along the dotted lines (14) and (15), two ventilations (16) and (17) fixed to the rigid walls create air currents between the rigid assembly and the flexible membranes (12) and (13).
Ces courants d'air agitent les membranes et ressortent par les orifices (18) et (19).These air currents stir the membranes and exit through the orifices (18) and (19).
Ceci permet d'agiter les membranes sans perturber l'intérieur de l'enceinte.This allows the membranes to be agitated without disturbing the interior of the enclosure.
PL 3 - Fig 3 L'enceinte est constituée d'un ensemble rigide (20) revêtue sur les faces intérieures, dedeux membranes souples (21) et (22) reliées à l'ensemble rigide suivant les pointillés (23) et (24) les membranes souples (21) et (22) sont libres, à leurs parties inférieures, des ventilateurs, par exemple, au nombre de 6: (25), (26), (27), (28), (29), (30), font pénétrer de l'air entre les parois rigides et les membranes souples, créant ainsi des courants d'air qui agitent les membranes. Ces courants d'air s'échappent aux parties basses des membranes, heurtent le fond de l'enceinte (31), remontent dans l'enceinte, entraînant dans leur turbulence ia poudre en suspension diffusée, qui tend à descendre naturellement par gravité.PL 3 - Fig 3 The enclosure consists of a rigid assembly (20) coated on the interior faces, two flexible membranes (21) and (22) connected to the rigid assembly along the dotted lines (23) and (24) the flexible membranes (21) and (22) are free, at their lower parts, fans, for example, 6 in number: (25), (26), (27), (28), (29), ( 30), make air penetrate between the rigid walls and the flexible membranes, thus creating air currents which agitate the membranes. These air currents escape to the lower parts of the membranes, strike the bottom of the enclosure (31), rise in the enclosure, causing in their turbulence ia powder in diffused suspension, which tends to descend naturally by gravity.
Dans cet exemple, les courants d'air agitateurs de membranes sont utilisés pour aider la poudre à rester en suspension. In this example, the agitating air streams from membranes are used to help the powder stay in suspension.
PL 4 - Fig 4 L'enceinte est constituée d'un ensemble rigide (32) et de 3 membranes souples (33), (34), (35) - les agitateurs (36) et (37) agitent les membranes (33) et (34), une soufflerie spéciale (38) fait onduler la membrane (35). La poudre en suspension dans l'enceinte diffusée par l'appareil (39) est repoussée vers l'axe longitudinal de la cabine c & nddant avec la trajectoire de la pièce (40) à revêtir ; une partie de la poudre se dépose sur la pièce, une autre partie descend naturellement par gravité et tend à se déposer sur la membrane (35); l'ondulation de cette membrane fait remonter la poudre et l'entraine vers l'extrémité (41) où elle peut-être récupérée dans un récipient (42). PL 4 - Fig 4 The enclosure consists of a rigid assembly (32) and 3 flexible membranes (33), (34), (35) - the agitators (36) and (37) agitate the membranes (33) and (34), a special blower (38) undulates the membrane (35). The powder in suspension in the enclosure diffused by the device (39) is pushed towards the longitudinal axis of the booth c & nddant with the trajectory of the part (40) to be coated; part of the powder is deposited on the part, another part descends naturally by gravity and tends to be deposited on the membrane (35); the undulation of this membrane causes the powder to rise and drives it towards the end (41) where it can be recovered in a container (42).
