摘要： An apparatus for actuating a valve. The apparatus comprises: an actuator device comprising a piston contained in a cylinder; the actuator device being actuated by a pressurized fluid, in particular compressed air; an opening/closing mechanism of a valve actuated by the actuator device; and a valve device to control and check the flow of pressurized fluid from and toward the actuator device in order to open/close the valve. The valve device is fixed to a front face of the actuator device on the side of the opening/closing mechanism of the valve.

摘要： A pressure relief valve for containers suited for the pneumatic loading of loose solid products, in particular silos. The valve comprises a valve body having a first end, which pneumatically communicates with the inside of the container, and a second end, which is associated to a flow control organ, which is subject to the action of corresponding closing membrane. The flow control organ periodically establishes a fluid communication between said valve body and a duct that communicates with the outside. The valve is characterised in that at least one portion of the duct that communicates with the outside is suited to be elastically deformed by the pressure difference existing between the inside of said container and the inside of the duct itself.

摘要： A screw conveyor to convey powdery material, in particular cement. The screw conveyor comprises: a transfer screw; and a trough containing the transfer screw; the trough being provided with an inlet section and an outlet section of the powdery material. The screw conveyor is characterized in that the screw comprises: at least a first screw portion having a first law of continuous variation of the pitches of the screw, which can be graphically represented by means of a first function having in at least one stretch a first derivative other than zero; and at least a second screw portion having a second law of continuous variation of the pitches of the screw, which can be graphically represented by a second function having in at least one stretch a first derivative other than zero. The first law of continuous variation of the pitches is different from the second law of continuous variation of the pitches.

摘要： A dosing apparatus (1) for dosing powdery, granular or flaked substances, comprises: a containment chamber (30) for receiving said substance; an homogenizing device (20) arranged internally of the containment chamber (30) and rotatable about an axis (Y) for homogenizing said substance; a dosing device (10) rotatable about a further axis (X) for conveying metered quantities of said substance outwardly the containment chamber (30); positioning means (50) for positioning the dosing apparatus (1) with respect to a support structure in an operative configuration. Said further axis (X) is offset with respect to said axis (Y), so that, in said operative configuration, a vertical plane (P) containing said axis (Y) is passing outside of the dosing device (10).

摘要： The invention relates to a dust collector for gaseous fluids and to a method for manufacturing the dust collector. The dust collector includes one or more filtering assemblies (1) that have filtering elements (2). The filtering elements (2) have a tubular extension. They are kept in contact with each other along a direction parallel to their length; the filtering elements (2) enclose, between them, flow channels (3).
The method for manufacturing a filtering assembly (1) of the dust collector includes the steps of: permanently deforming a sheet of a filtering material so as to obtain a corrugated sheet (8) with a cross-section defined by repetitions of ′Ω-shaped forms that are connected to each other; and coupling two deformed sheets, so as to keep the straight parts of the ′Ω-shaped forms in contact and to obtain rows of filtering elements (2).

摘要： A wastewater treatment plant. The plant comprises separating equipment for separating the solid particles from the liquid part. The separating equipment comprises, in turn, an inlet opening and an outlet opening, which are substantially arranged in line along a common directrix. In the fluid mass, there is present at least one fluid-dynamic profile, which is suited to help the detachment of the solid particles from the liquid part. The plant is characterized in that the separating equipment comprises, furthermore, a second fluid-dynamic profile. The two fluid-dynamic profiles define between one another a first preferential flow channel of the liquid mass.
