Abstract: Piece of continuous operating cycle sludge transfer equipment, which consists of two deposits (D1-D2), each one of which has a filling or suction circuit and another emptying or discharge circuit. A vacuum pump (Depr.) creates a depression in the first of the deposits, which causes the product to be sucked up from the outside, until said tank reaches a certain set level. Meanwhile, the other deposit is pressurized by means of a compressor (Compr.) coupled to a driving circuit, independent from the vacuum, in order for said deposit to be emptied and the sludge discharged towards an output channel at the adequate distance and height. When the first device is filled, the valves in the suction circuit of said deposit close automatically and those in the emptying circuit open, whilst the filling circuit in the other device opens and the emptying circuit closes.
