摘要： The invention provides a powder conveying drive including: a powder suction conduit (2) and a powder suction valve (5); a powder discharge conduit (3) and a powder discharge valve (6); a pump body (1) comprising a transfer chamber (13) that is configured with a powder inlet (11) connected to the powder suction conduit (2) and a powder outlet (12) connected the powder discharge conduit (3); and a powder sucking plunger (4) configured in upper part of the transfer chamber (13) and movable up and down inside the transfer chamber (13). When the powder sucking plunger (4) moves upward, the powder suction conduit (2) is opened by the powder suction valve (5) and the powder discharge conduit (3) is closed by the powder discharge valve (6) so that the powder is sucked into the transfer chamber (13) through the powder suction conduit (2). When the powder sucking plunger (4) moves downward, the powder suction conduit (2) is closed by the powder suction valve (5) and the powder discharge conduit (3) is opened by the powder discharge valve (6) so that the powder is discharged from the transfer chamber (15) through the powder discharge conduit (3). The powder inlet (11) is configured in the inner sidewall (130) of the transfer chamber (13), and the powder inlet (11) is above the powder outlet (12). Due to the powder discharge valve (6) is capable of overlapping the discharge of powder from the two transfer chambers (13) wherein the bottom wall (131) of the transfer chamber (13) is a porous fluidized plate, and the powder outlet (12) is configured on the surface of the porous fluidized plate, therefore the powder outflow is much smoother. Further, the quantity and stability of the powder feeding is improved.

摘要翻译： 本发明提供一种粉末输送驱动器，包括：粉末吸入管道（2）和粉末吸入阀（5）; 粉末排出管道（3）和粉末排出阀（6）; 泵体（1）包括配置有连接到粉末吸入管道（2）的粉末入口（11）和与粉末排出管道（3）连接的粉末出口（12）的传送室（13）。 以及构造在所述传送室（13）的上部并在所述传送室（13）内上下移动的粉末吸入柱塞（4）。 当粉末吸入柱塞（4）向上移动时，粉末吸入管（2）由粉末吸入阀（5）打开，粉末排出管道（3）被粉末排出阀（6）封闭，使得粉末 通过粉末吸入管道（2）被吸入转移室（13）。 当粉末吸入柱塞（4）向下移动时，粉末吸入管（2）被粉末吸入阀（5）关闭，粉末排出管道（3）由粉末排出阀（6）打开，使得粉末 通过粉末排出管道（3）从转移室（15）排出。 粉末入口（11）构造在传送室（13）的内侧壁（130）中，粉末入口（11）在粉末出口（12）的上方。 由于粉末排出阀（6）能够将来自两个转移室（13）的粉末的排出重叠，其中转移室（13）的底壁（131）是多孔流化板，并且粉末出口（ 12）构造在多孔流化板的表面上，因此粉末流出更平滑。 此外，粉末进料的量和稳定性提高。
