摘要： An airlock for the batch or continuous feeding of a material while obstructing the free flow of a gas. The airlock comprises a continuous belt having a substantially horizontal upper surface and a plurality of non-porous flights projecting out from the belt. Each flight has a free edge located outwardly from the belt. The free edges of the flights seal against a planar sealing surface located above and parallel to the belt. Particulates are transported on the upper surface of belt below and away from any potential grinding action between the moving free edges of the flights and the stationary sealing surface. The flights, located between the sealing surface and the belt, inhibit the flow of air through the airlock.

摘要： Coal powder is transported from a low pressure zone to an elevated pressure zone bypassing the powder from the low pressure zone to the top of the first one of a number of vertical vessels;passing the powder in each vessel by gravity as a moving bed from the top of the vessel to the bottom thereof;passing the powder from the bottom of each vessel but the last one to the top of the subsequent vessel by mechanical or pneumatic means;discharging the powder from the bottom of the last vessel to the elevated pressure zone.

摘要： Apparatus for removal of granular material from laterally spaced rows of containers having discharge ports whose lower edges are on a level with each other. A conveyor is in the space between the rows of containers substantially on a level with or slightly below the lower edges of the discharge ports. A tubular housing encloses the conveyor provided with inlet ports in its upper wall corresponding to the discharge ports of the containers and has an outlet orifice at the end of the conveyor. Sheet members bridge the gaps between the lower edges of the discharge ports and the adjacent edges of the upper wall of the tubular housing to form a roof of a chamber which is connected to the pressure side of a fan. There are slits in the sheet members providing upper orifices facing away from the discharge ports whereby the air current discharged from the chamber through the orifices will tend to move the material emerging from a discharge port towards the corresponding inlet port of the housing.
摘要翻译： 用于从具有其下边缘彼此平齐的排放口的横向隔开的容器排移除颗粒材料的装置。 输送机位于容器排之间的空间中，基本上处于与排出口的下边缘或稍低于排放口的下边缘的水平面上。 管状壳体围绕输送器，其在其上壁中具有与容器的排出口对应的入口端口，并且在输送机的端部具有出口孔口。 片材构件将排出口的下边缘和管状壳体的上壁的相邻边缘之间的间隙桥接以形成连接到风扇的压力侧的室的顶部。 片材中有狭缝，提供面向离开排出口的上部孔口，从而通过孔口从室排出的气流将倾向于将从排放口排出的材料移向壳体的相应入口端口。

摘要： A coal conveyor capable of transporting pulverized coal to a higher pressure zone. The conveyor comprising an upright pressure vessel and a feed pipe extending into and between two endless conveyor belts located within the vessel which mesh during their descent to form a first and second pressure seal before the discharge of the coal into the higher pressure zone.

摘要： A dry granular material transfer system and method for transfer of granular material such as sand in a dry state through a hose using pressurized air. On a base platform, a conveyor subsystem moves granular material placed on a lower portion to a higher portion while separating clumped material and allowing rocks and debris to fall away, spreading the granular material in a thin layer for ejection at the highest level. A containment subsystem receives granular material and contains the downward fall of material. A portioning subsystem has a turntable with blow-through chambers which receive granular material and move into line with an air inflow tube and air-material outflow tube, and the air-material mixture is blown through the air-material outflow tube and through a transfer hose.
