The utility model discloses a wear -resisting anti stifled defeated sediment pipeline. Should include by defeated sediment pipeline: outer wrapping steel pipe, its top is equipped with a plurality of first connecting holes along axis is spaced apart, wear -resisting ceramic pipe, it wears to establish as interior bushing pipe form the double cannula structure in the outer wrapping steel pipe, the top of this wear -resisting ceramic pipe along the axis spaced apart be equipped with a plurality ofly and outer wrapping steel pipe's the second connecting hole that first connecting hole is corresponding, and the endotheca steel pipe, there are a plurality of connection round steel at its top along axis space welding, and the upper end of these a plurality of connection round steel is fixed in outer wrapping steel pipe's the first connecting hole and the second connecting hole of wear -resisting ceramic pipe to wear to establish the inner chamber upper portion at wear -resisting ceramic pipe with the endotheca steel pipe, the lower part of endotheca steel pipe is spaced apart to have a plurality of fan -shaped breachs, the gas diffluence orifice plate is equipped with in fan -shaped breach department. Should defeated sediment pipeline is difficult block up, when starting once more after in short -term the stoppage in transit in the middle of the operation, also can dredge rapidly to dry -type deslagging system's security and reliability have been guaranteed.
