[0002] In the field of powder building material transfer, it is a conventional method to use bulk powder tank trucks for storage and transportation. When it is necessary to transfer the materials loaded in the bulk powder tank trucks to a cargo ship, a pneumatic ship loader is required, which can achieve environmental protection and efficient ship loading. For example, a mobile bulk material pneumatic ship loader with the publication number CN208843344U is a representative of pneumatic ship loaders. When in use, the bulk cement tank truck is connected to the feeding pipe of the ship loader through a pipeline (the working pressure in the tank is 0.18 Mpa), and the materials are conveyed to the buffer bin of the ship loader. The top of the buffer bin is equipped with a dust collector and a pressure valve to solve the pressure and dust during the material buffering process. The lower side of the buffer bin is a conveying system of the first air chute and the vertical feeding pipe, which transfers the materials to the blanking rotary box, and then conveys the materials to the ship through the second air chute and the telescopic cover. The whole conveying process is completely sealed and equipped with a dust collector. The second air chute and the telescopic cover are installed on the rotary boom, and at the same working station, ship loading can be realized in a fan-shaped area centered on the rotation point of the rotary boom and with the length of the rotary boom as the radius. The telescopic cover can be extended and retracted through the ship loading motor to meet the working water level requirements of ships from 1000 DWT to 5000 DWT. The whole set of equipment is installed on a mobile gantry crane, and through truck feeding, ship loading at different working stations can be realized. The whole equipment has greater working flexibility, is more environmentally friendly than the traditional structure form, and meets the national environmental protection standards.

[0032] When working, during the operation of loading a tanker onto a ship, the feeding pipe of the tanker is assembled with the connecting flange 104, and the exhaust pipe 203 is connected to an external dust collector through a hose. Then the tanker can start discharging materials while the electric control valve 204 is opened.
