Embodiment Construction

[0037] figure 1 Shown is an apparatus 1 for recovering recycled aggregate from concrete residues, in particular comprising unused excess concrete left in concrete mixers. The plant 1 comprises a feed device 2 into which the concrete mixer can discharge the concrete residue to be processed. The plant 1 also comprises a separation device 3, also called a concrete separator, adapted to receive a fluid containing concrete residues from the feed means 2, so that aggregates can be separated from this fluid.

[0038] Such as Figure 2-4 As shown in , the feeding device 2 comprises a holding tank 4 suitable for receiving concrete residues, for example discharged from one or more concrete mixers.

[0039] The holding tank 4 can be made of metal material, especially metal plate. Inside the holding tank 4, a main screw conveyor 5 is partially accommodated, which is adapted to collect fluid from a collection area 6 located on the bottom of the holding tank 4, and to transfer the fluid ...

Abstract

A feeding device for feeding a separation device (3) adapted to separate aggregates from concrete residues for recycling said aggregates, the feeding device comprising: - a container a holding tank (4) containing a fluid comprising a liquid in which said aggregates to be recycled are dispersed; - a main screw conveyor (5) for conveying The collection area (6) collects the fluid and transports the liquid and the aggregate contained in the fluid to the separation device (3); - along the bottom of the holding tank (4) At least one auxiliary screw conveyor (13) positioned on the surface (14) for conveying said fluid towards said collection area (6).

Description

technical field [0001] The invention relates to a feed device which is suitable for receiving concrete residues, for example discharged from a concrete mixer, and for conveying these residues to a concrete separator. The invention also relates to a device for recovering and reusing aggregates from concrete residues. Background technique [0002] Separation devices are well known, also known as concrete separators, capable of removing unused excess amounts of concrete left over from concrete mixers, or from cleaning fluids used to clean concrete mixers, or from any other equipment that handles concrete Recycle and reuse aggregates. [0003] Concrete separators of known type may comprise a hopper into which the concrete residue is discharged from the concrete mixer and an inclined screw conveyor which collects liquid containing aggregate to be recycled. The helical blades of the screw conveyor convey the aggregates upwards and discharge them from the discharge port. Said li...
