Ore pulp flash drum injection apparatus

The utility model discloses an ore pulp flash drum injection apparatus, including conical duct, orifice plate seat and orifice plate, conical duct one end link up with orifice plate seat one end meets, orifice plate foot stall portion is located to an orifice plate pot head, the feed inlet has been offered to orifice plate seat and conical duct link, and the toper discharge gate has been offered to its bottom, so the intracavity is equipped with the oxhorn type abrasion -resistant alloy taper pipe of intercommunication feed inlet and toper discharge gate in the orifice plate seat, in the toperdischarge gate is located to an orifice plate pot head, and the centre bore endotheca of its orifice plate is equipped with the carbide cover. Set up the oxhorn type abrasion -resistant alloy taper pipe, its aperture is reduced to the toper discharge gate by the feed inlet gradually, ore pulp more smooth and easy flow in the runner, reducing impact wearing and tearing. The orifice plate seat forms an organic whole with t
