The invention discloses a particulate matter unloading device special for a railroad hopper car, which is arranged at the bottom of each separated cargo storage cabin of the railroad hopper car, and comprises two sets of unloading mechanisms which are arranged at the bottom of each group of cargo storage cabin and are symmetrically arranged along the two sides of a car body, and air is supplied to the two sets of unloading mechanisms in parallel by an air supply system connected with an air compression mechanism; each unloading mechanism comprises an unloading funnel, an unloading mixer and an annular pressurizer. The gravity and pressure air mixed unloading technology is adopted, and the unloading speed and the unloading capacity of the vehicle are improved through the specific function of the annular pressurizer; an unloading mixer flows into a mixing tank under the gravity action of particulate matters, meanwhile, pressure air enters the mixing tank from a porous plate to form a gas-solid two-phase mixture with the particulate matters, so that cargoes have certain flowability and flow out from a straight-through pipe of an annular pressurizer, and meanwhile, the unloading efficiency is improved under the assistance of negative pressure generated by the annular pressurizer; the bottoms of all the bins of the tank truck are symmetrically arranged to achieve simultaneous unloading on the two sides of the truck body, and the unloading capacity is improved.

    本发明公开了一种专用铁路漏斗车的颗粒物卸货装置,装置设置于铁路漏斗车各分隔式储货舱底部,包括设置于每组储货舱底部、沿车体两侧对称布置的两套卸货机构,两套卸货机构由与压缩空气机构连接的供风系统平行供气;每套卸货机构包括卸货漏斗、卸货混合器和环形加压器。本发明采用重力和压力空气混合卸货技术,利用环形加压器特有功能,提高车辆的卸货速度和卸货能力;卸货混合器利用颗粒物重力作用流入混合槽内,同时压力空气从多孔板进入混合槽与颗粒物形成气固两相混合物,使货物具有一定的流动性,从环形加压器直通管流出,同时辅以环形加压器产生的负压,提高卸货效率;在罐车各料仓底部对称布置可实现车体两侧同时卸货,提高卸货能力。
