Dry drainage assisted filling system

The invention relates to the technical field of tailing filling processes, in particular to a dry discharge assisted filling system which comprises a deep-cone thickener, and an underflow opening of the deep-cone thickener is connected with a dry discharge system and a filling system. The filling system comprises a stirring system and a filling pump which are connected with each other, and the stirring system is also communicated with an underflow port of the deep-cone thickener; the dry discharge system comprises a drum screen and a filter press which are connected with each other, and the drum screen is also communicated with an underflow port of the deep-cone thickener. Compared with the prior art, for the rake pressing risk of the deep-cone thickener, the additionally-arranged dry discharging system can filter ore pulp generated during accident treatment into sand in a pressing mode, how to treat the ore pulp does not need to be considered any more, and the accident treatment time can be greatly shortened
