<p>Device which is intended to be installed in registration with the outlet mouth of the filtering elements which comprise a cage covered by a porous sleeve to retain the particles suspended in the duty air to be filtered. The device can be fixed at the proximity of the outlet mouth of the filtering element and compressed air is injected towards the inside of each filtering element in order to clean the porous sleeve and remove all particles which are adhered thereto same during the filtering operation. To this effect, the device comprises a telescopic nozzle (1) fixed to the outlet mouth (4) of the filtering element (5) by means of arms (3) so that in the active position of the nozzle the last section of said nozzle through which air comes out for the cleaning of the sleeve is partially introduced inside said outlet mouth (4).</p> |
