Preferably, the axis of rotation 42 is oblique and the basket has a cubic shape, the diagonal of which is substantially on the axis 42.

La cuve 1 porte à l' extérieur une pluralité de générateurs 9 d' ondes ultrasonores.The tank 1 carries outside a plurality of generators 9 of ultrasonic waves.

La cuve 1 est destinée à contenir un bain 2 de liquide de nettoyage. Le niveau est repéré 24 et il est établi de manière à baigner le panier 41 et la ou les pièces à contrôler 6. Un détecteur de niveau 10 est utilisé pour mesurer le niveau du bain.The tank 1 is intended to contain a bath 2 of cleaning liquid. The level is marked 24 and it is established so as to bathe the basket 41 and the part or parts to be checked 6. A level detector 10 is used to measure the level of the bath.

La cuve contient un organe 5 d' aspersion ou d' arrosage du liquide de nettoyage. Cet organe est par exemple constitué par une douche rotative.The tank contains a member 5 for spraying or spraying the cleaning liquid. This body is for example constituted by a rotary shower.

La sortie inférieure 111 de la cuve communique avec une botte de filtration 3 contenant des filtres 31. Un dispositif de serrage rapide 32 permet la mise en place rapide des filtres. A la sortie de la boîte de filtration 3, le liquide est repris par un circuit de recyclage. La boîte est raccordée à une tubulure 71 qui débouche dans une cuve 72 de récupération du liquide située à la partie inférieure du dispositif. Une vanne 73 est placée sur la tubulure 71. Une pompe 91 déplace le liquide dans une tuyauterie 92 raccordée d' un côté au réservoir et de l' autre côté à 1' organe 5 d' aspersion du liquide. Sur le circuit est disposé un clapet antiretour 93 qui autorise le passage du liquide dans un seul sens, de bas en haut.Un filtre cartouche 94 est, par ailleurs, disposé sur le circuit.Il assure au liquide d' arrosage une qualité telle qu' aucune impureté transportée par celuici ne puisse être prise en compte lors de la mesure.The lower outlet 111 of the tank communicates with a filtration boot 3 containing filters 31. A quick clamping device 32 allows the filters to be put in place quickly. At the outlet of the filtration box 3, the liquid is taken up by a recycling circuit. The box is connected to a tube 71 which opens into a tank 72 for recovering the liquid located at the bottom of the device. A valve 73 is placed on the tubing 71. A pump 91 moves the liquid in a pipe 92 connected on one side to the reservoir and on the other side to one member 5 for spraying the liquid. On the circuit is arranged a non-return valve 93 which allows the passage of the liquid in one direction, from bottom to top. A cartridge filter 94 is, moreover, disposed on the circuit. It ensures the quality of the spraying liquid that '' no impurity transported by it can be taken into account during the measurement.

La cuve de travail 1 présente un évent 13 qui se prolonge vers le bas par un tube de purge 14 débouchant en partie basse dans la cuve de récupération 72. Le passage du liquide est contrôlé par une électrovanne 15 montée sur le tube 14. The working tank 1 has a vent 13 which is extended downwards by a purge tube 14 opening at the bottom into the recovery tank 72. The passage of the liquid is controlled by a solenoid valve 15 mounted on the tube 14.

Le dispositif comporte un circuit de mise en pression pneumatique 8 qui est destiné à mettre la cuve sous pression. Ce circuit de mise sous pression se compose d'une canalisation 81 d'amenée d'air comprimé débouchant dans la cuve, d' un, clapet antiretour 82, d' un détendeur 83, de filtres 84 et 85 et d' une électrovanne 86 et d'une soupape de sécurité tarée 100.The device comprises a pneumatic pressurization circuit 8 which is intended to put the tank under pressure. This pressurization circuit consists of a pipe 81 for supplying compressed air opening into the tank, a non-return valve 82, a pressure reducer 83, filters 84 and 85 and a solenoid valve 86 and a calibrated safety valve 100.

Le fonctionnement du dispositif va maintenant être expliqué.The operation of the device will now be explained.

On procède préalablement au tarage du dispositif en effectuant le rinçage du dispositif. A cet effet, on arrose l'intérieur de la cuve par l' organe d1 aspersion 5, les filtres 31 étant enlevés.The device is tared beforehand by rinsing the device. To this end, the interior of the tank is watered by the spraying member 5, the filters 31 being removed.

On place ensuite la pièce à contrôler 6 dans son panier et on ferme la cuve par le couvercle 12. On met les filtres 31 en place dans la boîte de filtration 3.The part to be checked 6 is then placed in its basket and the tank is closed by the cover 12. The filters 31 are put in place in the filtration box 3.

Le mécanisme de mise en rotation 4 est mis en marche et l' arrosage du liquide de nettoyage est déclenché. La vanne 73 étant fermée, le liquide de travail remplit la cuve jusqu'à un niveau de référence déterminé par le détecteur 10. A ce moment-là, l'arrosage est arrêté. Les ultrasons sont mis en route pendant un temps déterminé par minuterie. Après écoulement de ce temps, ils sont coupés et on déclenche la mise sous pression de la cuve l. On ferme l' électrovanne 15 du circuit de purge et on ouvre le circuit 8. Du fait de la mise en pression, le liquide est refoulé au travers des filtres 31.The rotation mechanism 4 is started and the spraying of the cleaning liquid is started. The valve 73 being closed, the working liquid fills the tank up to a reference level determined by the detector 10. At this time, watering is stopped. The ultrasound is switched on for a time determined by timer. After this time has elapsed, they are cut off and pressure is applied to the tank l. The solenoid valve 15 of the purge circuit is closed and the circuit 8 is opened. Due to the pressurization, the liquid is discharged through the filters 31.

On effectue un dernier rinçage du dispositif puis une nouvelle mise sous pression. Le liquide passe à travers les filtres. Lorsque tout le liquide est passé (chute de pression dans la cuve), le cycle est terminé.A final rinsing of the device is carried out then a new pressurization. The liquid passes through the filters. When all the liquid has passed (pressure drop in the tank), the cycle is finished.

Les saletés de la pièce sont récupérées sur les filtres 31. De ce fait, il est possible de mesurer, par pesée de ceux-ci, la propreté de la pièce 6.The dirt in the room is collected on the filters 31. Therefore, it is possible to measure, by weighing them, the cleanliness of the room 6.

Il est bien entendu que l' on peut sans sortir du cadre de l'invention imaginer des variantes et des perfectionnements de détails et de même envisager l' emploi de moyens équivalents. It is understood that it is possible without departing from the scope of the invention to imagine variants and improvements of details and even envisage the use of equivalent means.
