Abstract
The invention relates to a silo for sludge, especially sewage sludge, comprising a sludge-receiving part (12), a feeding part (16), said feeding part being located above the sludge-receiving part (12) and communicating with said sludge-receiving part (12) via a inlet (14), and a sludge-discharge device. Said sludge-discharge device is located in the lower area of the sludge-receiving part, and can preferably be connected to a pipeline system. According to the invention, a separator device (18) for removing foreign bodies is located in the area of the feeding part (16) so that the sludge which is temporarily stored in the silo can easily be used later on. Said separating device for removing foreign bodies (18) has a sieve grate (20) covering the inlet (14) and at least one counter-surface (22) positioned above said sieve-grate (20). Said sieve-grate and said counter-surface are able to move in relation to each other as sludge pushes through the sieve openings of said sieve-grate.
