Agitators and jet cleaners are used (cleaning equipment in rain pools, water wastewater practice, 1999, No. 2, pages 26-32). The main difference in wastewater technology between the cleaning devices is the solids load that is generated during the emptying of the storage rooms. Depending on the type of pool, the surge generating devices cause a flushing surge, which is sent directly to the sewage treatment plant. The swirling devices bring about an equalization of the solids loads, which are continuously added to the further discharge system during the clearing of the storage space.

Abstract

Des dispositifs à tourbillonnement tels que des mélangeurs et des dispositifs de nettoyage à jet sont utilisés en plus de dispositifs générateurs de jets tels que des dispositifs de rinçage à bascule, des dispositifs de rinçage à clapet et des dispositifs de rinçage par le vide, pour nettoyer la base de chambres de stockage destinées à des liquides, en particulier à de l'eau mixte. L'invention concerne un dispositif de nettoyage à tourbillonnement, un dispositif de nettoyage à jet oscillant, l'énergie du jet de liquide étant utilisée de deux manières, à savoir pour nettoyer le récipient de stockage et pour faire osciller le dispositif. Le couple de rotation nécessaire à l'oscillation est généré par positionnement du/des tuyau(x) à jet (18) en dehors de l'axe de rotation, ou par l'intermédiaire de leur configuration qui entraîne une modification de la force d'impulsion du jet de liquide lorsque celui-ci traverse le(s) tuyau(x). Pour modifier la direction d'oscillation, le dispositif comporte un dispositif de commutation (20), ce qui supprime les inconvénients que présentent des entraînements électriques et/ou hydrauliques supplémentaires servant à faire osciller les dispositifs de nettoyage à jet, et les inconvénients de dispositifs de nettoyage à jet rotatifs qui peuvent tourner uniquement dans un sens.
