Abstract

It is described a washing device (10) of a filterpress (100) comprising a support carriage (1), wherein said support carriage (1) is slidingly mounted on sliding guides (6, 7) above a plurality of filtering plates (20) aligned to each other along a longitudinal extension direction (X). A washing group (2) comprises at least one nozzle (3) that is adapted to spray a washing fluid (3'). Are, furthermore, provided first actuating means (4) that is adapted to move the support carriage (1) according to said longitudinal extension direction (X), and second actuating means (5) that is adapted to actuate said washing group (2) according to a top to down direction and vice-versa (V), such that the washing group (2) enters in a space (D) defined between two filtering plates (20) adjacent to each other in an open configuration.

IPC Classes  ?

• B01D 25/164 - Chamber-plate presses, i.e. the sides of the filtering elements being clamped between two successive filtering plates
• B01D 25/172 - Plate spreading means
• B01D 25/38 - Removal of filter cakes by moving parts, e.g. scrapers, contacting stationary filter elements

Abstract

It is described a filterpress structure (100) comprising a support frame (10) having a first fixed shoulder (1) and a second fixed shoulder (2) opposite to each other; a movable shoulder (3) arranged between said first fixed shoulder (1) and said second fixed shoulder (2). A plurality of filtering plates (20) are functionally arranged between the movable shoulder (3) and the second fixed shoulder (2) that extend along a longitudinal axis (X). Actuating means (40) are adapted to move selectively the movable shoulder (3) between a closed configuration and an open configuration of the filtering plates (20). The actuating means (40) comprise at least one first couple of pneumatic actuating cylinders (41) parallel to each other arranged on a first reference plane (P1) and a second couple of pneumatic actuating cylinders (42) parallel to each other arranged on a second reference plane (P2) overlapped to said first reference plane (P1).

Abstract

Support structure (1) of a treatment plant of mud, wherein the plant comprises a plurality of treatment machines (2, 2a, 2b, 2c) that is adapted to receive as input a flow of mud or sludge to treat and to obtain as output a solid component and a liquid component. The support structure (1) comprises at least one support frame (3) that comprises a plurality of longitudinal (31) and transversal beams (32), the longitudinal and transversal beams defining a base quadrant (33), lock means (4) of releasable type arranged on the base quadrant adapted to lock at least one treatment machines. In this way, each treatment machine is integral to the support frame. Furthermore, hanging means (5) arranged on the support frame that define a plurality of hanging points (51) is provided, such that the support frame can be moved by a lifting means maintaining a handling configuration substantially parallel to the plane of the ground, and, in order to be loaded or discharged on/from a vehicle.
