摘要： Technology for efficiently extracting fiber from a feedstock containing fiber. A subunit has a mesh drum configured as a rotatable cylinder with mesh in at least part of its surface, and a case that houses the mesh drum. The case has a first opening and a second opening that communicate with a first area, and a third opening that communicates with a second area. First screened material is supplied from the first opening to the first area. The subunit discharges from the third opening waste, which is a first component of the first screened material moved by an air current from the first area to the second area, and discharges from the second opening by an air current processing feedstock, which is a second component of the first screened material that does not pass through the mesh drum with the air current and remains in the first area.

摘要： A system for screening fluid-borne material from a fluid that carries particulate matter along with the material, e.g. for screening usable fibers in papermaking or tissue making white water that also contains waste material such as fines and ash. The system employs a flexible and pliable screen to which the fluid is applied. The screen is supported in a suspended manner from a frame. The fluid is directed onto an inside surface defined by the screen, and the location at which the fluid strikes the screen is varied so as to result in bending and flexing of the screen due to the flexibility and pliability of the screen material. In this manner, the configuration of the screen drainage passages is continuously altered, to provide a self-cleaning action that prevents the screen passages from plugging or blinding over. In one form, the screen is generally frustoconical, and the fluid is applied to the inside surface of the screen in a manner which results in rotation of the screen. The material retained on the screen is directed toward a discharge opening defined by the lower end of the frustoconical screen, and the waste water including the particulate matter passes through the screen and is collected in a waste water collection tank. In another form, the screen is suspended from a frame to form a trough configuration having an open discharge end. The frame is movable in either an axial direction or a transverse direction, to cause movement of the screen and to obtain the desired flexing and bending of the screen to self-clean the screen drainage passages.
摘要翻译：用于从携带颗粒物质的流体中与液体载体材料一起筛选的系统，例如，用于筛选造纸或组织制造白水中的可用纤维，还含有诸如细粉和灰分的废料。该系统采用柔性和柔韧的屏幕，流体被施加到该屏幕上。屏幕以悬挂的方式从框架中支持。流体被引导到由屏幕限定的内表面上，并且流体撞击屏幕的位置变化，从而由于屏幕材料的柔韧性和柔韧性而导致屏幕的弯曲和弯曲。以这种方式，连续改变丝网排出通道的结构，以提供防止屏幕通道堵塞或堵塞的自清洁动作。在一种形式中，屏幕通常是截头圆锥形的，并且以导致屏幕旋转的方式将流体施加到屏幕的内表面。保持在屏幕上的材料指向由截头圆锥形筛网的下端限定的排出口，并且包括颗粒物质的废水通过筛网并被收集在废水收集罐中。在另一种形式中，屏幕从框架悬挂以形成具有开放放电端的槽构造。框架可以沿轴向方向或横向方向移动，以引起筛网移动，并获得筛网的所需弯曲和弯曲以自动清洁筛网排放通道。

摘要： A two stage pulp screening device is disclosed of particular use as a high capacity unit replacing two separate units. The device has an upper pulp screening chamber and a lower pulp screening chamber, the lower chamber has a stationary cylindrical screen with a streamlined rotor mounted therein for rotation about a vertical axis. The upper chamber has a further stationary cylindrical screen with at least one foil cleaning bar mounted therein for rotation about the same vertical axis. In the upper chamber around the further screen is a stationary inlet baffle which forms an annular space between the screen and the baffle. In this space is at least one helical baffle which forms a spiral passage descending beside the screen. A reject discharge is provided in the lower portion of the annular space for removing all rejects and pulp slurry that has not passed through the screen.

摘要： Screening apparatus having a valve in the rejects conduit controlling the discharge of material therethrough. The valve includes a plurality of chambers separated by a wall containing one or more openings of smaller cross section than the chambers and is rotatably driven at a predetermined speed by a drive motor to alternately connect each chamber to the upstream portion of the rejects conduit while the other chamber is connected to the downstream portion of such conduit. The drive motor is reversible to automatically reverse the direction of rotation of the valve in the event that the latter, during rotation in either rotary direction, becomes jammed by rejected material; and a valve in the inlet conduit of the screening apparatus is automatically closed when the first-mentioned valve is not in operation.
