Abstract

The decantation and recycling tank comprises a first decantation compartment (1) provided with a first opening (21) that is placed in an upper portion of the first compartment and is equipped with a first removable decantation basket and a removable filtering basket (22), which is superimposed above the first removable decantation basket so as to perform the filtration of the washwater discharged through the first opening before the decantation in the first decantation basket, and a second decantation compartment (2) provided with a second opening. The decantation and recycling tank comprises a first decantation compartment (1) provided with a first opening (21) that is placed in an upper portion of the first compartment and is equipped with a first removable decantation basket and a removable filtering basket (22), which is superimposed above the first removable decantation basket so as to perform the filtration of the washwater discharged through the first opening before the decantation in the first decantation basket, a second decantation compartment (2) provided with a second opening that is placed in an upper portion of the second decantation compartment and is equipped with a second removable decantation basket, a reservoir for recovery and storage of clear water equipped with a clear water discharging unit, a removable receptacle distributor (4) of washwater mounted above the first and second decantation compartments and configured to produce a flow of washwater from a concrete mixer or a concrete production unit towards the filter basket and/or the second basket, a flow unit (5) adapted to evacuate a supernatant water contained in the first and second decantation compartments towards the reservoir, and a hopper mounted on a sliding support at the top of and along the receptacle distributor of the washwater to channel the water discharged in the hopper towards the receptacle distributor. The first decantation compartment is isolated from the second decantation compartment and the reservoir by a partition. The receptacle distributor of the washwater extends the partition, and is shaped so as to allow the overflow of the washwater from the first decantation compartment towards the second decantation compartment when the first decantation compartment is completely filled. The first and second decantation compartments and the reservoir are adjacent to each other. The tank further comprises a housing that is present in communicate with the first and/or second decantation compartments of a vent channel so as to create a communicating vessel system arranged between the housing and the first and/or second compartments. One of the first and second decantation baskets comprises a pair of lever arms intended to cooperate with a supporting unit secured to the tank. Each lever arm is mounted in a rocker to a wall of the baskets, and has a first end protruding from the baskets to abut against the supporting unit, and a second end that is opposite to the first end and is equipped with a fastening unit adapted for constituting an anchoring point and traction for the extraction of the baskets form the tank. The first and second decantation baskets comprise a removable door with a side wall of the baskets. The filtering basket is equipped with a permeable mesh bottom. The flow unit comprises a main conduit formed by a rigid part terminated by an inlet opening and by a flexible part terminated by an outlet opening. A buoyant member is adapted to maintain the inlet opening at a waterline, and is disposed at the inlet opening. The main conduit is connected to a purging unit by injection of air or of water under pressure in the main conduit.
