    摘要： A power sieve has a generally planar and longitudinally extending frame having upstream and downstream ends and a pair of laterally spaced side members extending longitudinally between the ends, a generally planar screen spanned longitudinally within the frame, and a plurality of longitudinally spaced and substantially parallel beater beams underneath the screen and having beam ends juxtaposed with the frame side members. Respective horizontally extending leaf springs each have one end secured to the respective side member and another end secured to the respective beam end. Thus the beams can move generally vertically on the springs. Respective beater arms extending generally parallel to the screen from the beater beams have outer ends engageable with the underside of the screen. In addition, respective actuation arms extending radially from the beater beams have outer ends connected to a rigid longitudinally extending link connected in turn to a linear drive on the frame connected to the link for horizontally reciprocating the link and thereby simultaneously and synchronously pivotally oscillating the beater beams with the respective beater arms to hammer the outer ends of the beater arms against the screen. In this manner when the screen is inclined down from the one end and particulate material is loaded onto the screen at this end the particulate material migrates down along the screen to the other end with the smaller fractions falling through the screen.

    摘要翻译： 动力筛具有大致平面且纵向延伸的框架，其具有上游和下游端部以及在端部之间纵向延伸的一对侧向间隔开的侧部构件，在框架内纵向间隔开的大致平面的屏幕，以及多个纵向间隔开且基本上平行的打浆机 横梁在屏幕下方并且梁端部与框架侧构件并置。 相应的水平延伸的板簧各自具有固定到相应的侧部构件的一端和固定到相应的梁端部的另一端。 因此，梁可以在弹簧上大致垂直地移动。 从打浆机梁大致平行于筛网延伸的各个搅拌器臂具有可与丝网底面啮合的外端。 另外，从冲击波束径向延伸的相应的致动臂具有连接到刚性纵向延伸的连杆的外端，连接到连接到连杆上的框架上的线性驱动器，用于使链节水平往复，从而同步并同步地摆动搅拌器 梁与各自的打击臂一起将击打臂的外端撞击屏幕。 以这种方式，当屏幕从一端向下倾斜并且在该端部将颗粒材料装载到屏幕上时，颗粒材料沿着屏幕向下移动到另一端，较小的部分通过屏幕落下。

    摘要： A screen apparatus has a frame having a pair of spaced-apart longitudinal beams whose ends are bridged by a pair of spaced-apart transverse beams. A central longitudinal member or wall equidistant between the longitudinal beams has ends secured to the transverse beams. Transverse struts extend between the longitudinal beams and through the central wall and support a screen. The frame is mounted for limited displacement relative to a fixed support and a drive motor is fixed to the central member and carries an eccentric for limitedly displacing the frame and the screen in a vibratory or oscillatory manner.

    摘要： Vibratory separating apparatus wherein the screen basket assembly is mounted on the base by mounting means including resilient elements which are resilient laterally and longitudinally to be longitudinally extensible and compressible to permit orbital vibrating movement of the assembly relative to the base. The orbital vibrating movement is created by vibration generating means including rotatably driven eccentric means; and mounting means are provided for mounting the vibration generating means at a plurality of alternative positions adjusted longitudinally of the screen whereby the rate of advance of material longitudinally along the screen feed face by orbital vibrating movement of the screen is adjustable independently of the intensity and the amplitude of the vibrations by varying the location at which the vibration generating means is mounted by the mounting means.

    摘要： An apparatus for vibrating a material separator provides selective horizontal and vertical high frequency vibratory forces to the separator. The amplitude of the forces can be individually controlled while the machine is operating. The precise direction of the horizontal force can be set to obtain the desired pattern of material travel over the screen. Also disclosed is a manner in which the vibratory motion caused by the vertical component force can be utilized to prevent screen blinding.

    摘要： Liquid suspensions are classified by means of a substantially horizontal vibrating screen, whereby the suspension is supplied to the bottom part of the screen. The screened material passes through the screen, taken along by the raising stream of the suspension and is removed from the top part of the screen. The part of material which cannot pass the screen remains in the bottom part, wherefrom it is drained. The screening effect is thus not reduced by solid material settling on the screen surface.
