    • In a dredging apparatus, a suction head relocates matter by sucking particulate matter from a bed of a body of water. The suction head includes a first conduit (C1) having an inlet; a second conduit (C2) having an inlet and an outlet, connected in series with C1. The C2 outlet opens to the C1 inlet via a mixing region. A third conduit (C3) has an inlet and an outlet, the latter opening to C1 via a restriction and the mixing region. A fluid may be fed under pressure through the C3 inlet and conveyed to the mixing region via the restriction, reducing the pressure of the fluid passing into the mixing region, the reduction causing matter to be sucked through the C2 inlet and conveyed though C2 to the mixing region, the matter being entrained with the fluid and exiting the mixing region via C1.
    • 在疏浚装置中,抽吸头通过从水体的一个床中吸取颗粒物质来重新定位物质。 吸头包括具有入口的第一导管(C1) 具有与C1串联连接的入口和出口的第二导管(C2)。 C2出口通过混合区域通向C1入口。 第三导管(C3)具有入口和出口,后者通过限制和混合区域向C1开口。 流体可以在压力下通过C3入口进料并通过限制输送到混合区域,减少流入混合区域的流体的压力,还原引起的物质被吸入到C2入口并通过C2输送到 混合区域,该物质被流入并通过C1离开混合区域。
