摘要:
An electroflotation method for purifying vibratory finishing wastewater and wastewater in general, which consists in introducing a liquid to be purified into a containment tank (1) provided with at least one pair of electrodes (2,3) with an aluminum or iron anode and with cathodes made of non-oxidizing material, which are connected to an electric power source, and in performing electroflotation to produce aluminum or iron hydrate; corpuscles made of an electrically non-conducting material are introduced into the liquid to be purified and the containment tank (1) is subjected to a vibration, with continuous separation of the deposits from the electrodes (2,3).
摘要:
Method and apparatus for vibrating mass treatment of metal surfaces, comprising finishing means forming, together with the workpieces being treated, an incoherent mass which is caused to advance along a preset path (A) at the end whereof the separation of the treated workpieces from the finishing means is effected and the finishing means are cycled back. To control the duration of the treatment cycle, a controlled portion of the finishing means is introduced into the path (A) at one or more locations (25) in a zone downstream at a distance from the beginning zone (8) of the cycle to form a weir counterhead and slow down the advancing incoherent mass upstream.
摘要:
The present invention relates a circular vibratory finishing machine (1) with automatic separation of the parts to be treated (3) and of the finishing media (4), comprising a circular tank body (2) for containing the parts to be treated (3) and the finishing media (4) and provided with a bottom (10) that has an extraction ramp (11) that can be engaged by an extraction flap (15) for conveying the mass being treated in the tank body (2) toward a grille (20) for separating the treated parts. The particularity of the invention consists in that it comprises, below the separation grille (20), an intermediate grille (30) is provided for selecting the finishing media (4) in order to convey the reusable finishing media (4) into the tank body (2) and the undersized finishing media (5) onto a lower surface (40) for outward evacuation.

摘要:
A granular abrasive substance for the surface treatment of products in general, which comprises a mixture of polyester and abrasive in powder form with a hardening catalyst. The particularity of the invention is constituted by the fact that it comprises, in the mixture, aluminum in the metallic state and its salts, and a pH regulator.
摘要:
The present invention relates to a vibrating machine, particularly for the mass drying of metallic bodies, with automatic unloading of the dried parts, which comprises a tank body (1) provided with vibrating means associated with a supporting frame by means of the interposition of anti-vibration means. The tank body (1) is internally provided with a bottom (3) defining a ramp-like portion (4) which leads to a selection plane having an initial fixed portion (11) a central openable portion (13) and a terminal unloading portion (14). The peculiarity of the invention is constituted by the fact that the openable central portion (13) comprises a first wing (20) which is pivoted to the initial fixed portion (11) and a second wing (21) which is pivoted to the terminal unloading portion (14). The wings (20,21) can be rotated to place them in a working position, whereat the first wing (20) is rotated downward for causing material to fall into the tank body (1), and in an unloading position, whereat the first wing (20) and the second wing (21) are mutually aligned for the outward conveyance of dried parts.

The present invention relates to a vibrating machine, particularly for the surface finishing of parts, with automatic unloading means, which comprises a tank body (1) provided with vibration means and connected to a supporting frame (2) with the interposition of anti-vibration means. The tank body (1) is provided with an internal bottom (3) which defines a ramp-like portion (4) for sending the parts toward an unloading plane (5) by means of a connecting wing (6) associated with the unloading plane (5) and removably associable with said ramp-like portion (4) for the extraction of the finished parts. The peculiarity of the invention resides in the fact that it comprises a lower detector (12) of the positioning of the wing (6) in lowered position on the ramp-like portion (4) and at least one intervention timer which controls the time of passage of the connecting wing (6) from the raised position to the lowered position and drives the actuation of motor means (10) for moving the connecting wing.
