    • A main screw feeder having a main screw housing set at an incline from the base of a bin. The main screw housing has two outlets, the advanced outlet and the recycle outlet. The advance outlet communicates with a metering screw housing in which twin screws of identical pitch are rotated in synchronous, intermeshed revolution. The delivery outlet for the metering screw housing communicates with the processing stages. The recycle outlet is positioned at an elevation higher than the advance outlet and discharges to the bin. A flow measuring device measures the return flow of granulated or powdered material expelled from the recycle outlet. The flow measuring device projects a prestressed cable into the recycle path of the return flow. A device for measuring any deflection of the cable and fluctuations in the tension thereon produce a signal which is a function of the return flow and which is used to control the speed of the main screw feeder.
    • 主螺旋进料器,其具有设置在从箱的底部倾斜的主螺钉壳体。 主螺丝壳体有两个出口,先进的出口和再循环出口。 前进出口与计量螺钉壳体连通,其中相同节距的双螺杆在同步,相互啮合的旋转中旋转。 用于计量螺旋壳体的输送出口与处理阶段连通。 再循环出口位于高于提前出口的高度处,并排放到料仓。 流量测量装置测量从再循环出口排出的颗粒状或粉状材料的返回流量。 流量测量装置将预应力的电缆投入回流的再循环路径。 用于测量电缆的任何偏转和其上的张力波动的装置产生作为返回流量的函数的信号,其用于控制​​主螺旋给送器的速度。

    • The present invention relates to a device for extracting and proportioning pulverulent products comprising a hopper and coaxial screws with threads of opposite directions, driven in rotation in a cylindrical conduit, which screws are separated from each other by the wall of a tube coaxial to the screws and to the conduit, the screw of smaller diameter rotating inside the tube to convey the product therein in one direction and the screw of larger diameter rotating outside said tube to convey the product in the opposite direction, in the space defined between the tube and the conduit, said latter comprising on its periphery at least one orifice for the flow of the product, wherein said screws are composed of wires helically wound in the manner of a spring, and the tube in which the so-called extraction screw, of smaller diameter, is mounted, comprises on its periphery and on the hopper side an opening for the inlet of the product, in front of which said screws extend at least partially, which product, after having passed through said tube, is taken up by the screw of larger diameter and is transported in opposite direction and to outside the tube, on the hopper side to exert a constant pressure at inlet level, with a view to avoiding the effects of "vault" above the inlet opening and simultaneously to cause the product to pass through an orifice located on the periphery of the conduit.
    • 本发明涉及一种用于提取和配比粉末产品的装置,其包括料斗和具有相反方向的螺纹的同轴螺钉,该圆筒形管道旋转驱动,这些螺钉通过与螺杆同轴的管壁相互分离 并且对于导管,较小直径的螺杆在管内旋转以在一个方向上传送产品,并且更大直径的螺杆在所述管的外部旋转,以在相对的方向上在与管和管之间限定的空间中传送产品 后者在其周边上包括用于产品流动的至少一个孔口,其中所述螺钉由以弹簧的方式螺旋缠绕的线组成,并且其中所述的抽出螺杆较小直径的管 安装在其周边上且在料斗侧上具有用于产品入口的开口,其前面至少部分地延伸有所述螺钉, 该产品在通过所述管之后,被较大直径的螺杆吸收并沿着相反的方向输送到管的外侧,在料斗侧以在入口水平上施加恒定的压力,以避免 “保险库”在入口开口上方的影响,同时使产品通过位于管道周边的孔口。
