摘要： A pressure screen for cleaning a fibrous stock including a screen element which has a rotationally symmetrical configuration about a screen axis. The screen element divides the pressure screen into an inlet chamber and an accepted stock chamber. The inlet chamber is connected at a first axial end with a suspension inlet and at a second axial end with a reject outlet. The accepted stock chamber is connected with an accepted stock outlet. The pressure screen also includes a rotor situated in the inlet chamber and including a plurality of rotor blades. The rotor rotates about the rotational axis relative to the screen element. The plurality of rotor blades is arranged on a plurality of circumferential planes of the rotor. The width of an annular gap between the rotor and the screen element decreases from the suspension inlet to the reject outlet.

摘要： The value-minerals are captured by gravity-separation, from a low-grade slurry. The ratio of liquids-to-solids in the slurry affects the efficiency of capture, and an ideal liquids/solids ratio is the ratio at which the efficiency of capture is at a maximum. The ideal ratio is different for different particle-sizes. The procedure includes dewatering the slurry, dividing the dry particles by particle-size, and feeding the several size-divided dry-streams into respective capture-stations. Prior to each dry-stream entering its respective capture-station, make-up water is added to the dry-stream in such quantity as to bring the liquids/solids ratio up to the ideal, for that particle-size. The procedure makes it simple to provide accurate measurement of, and accurate control of, the liquids/solids ratio.

摘要： A screen basket with replaceable profiled bars and method of making such screen basket are described herein. The screen basket includes profiled bars evenly spaced circumferentially to form a plurality of continuous slots that covers the whole basket length. The profiled bars are fixed in place by a backing structure, including support rings. In pulp and paper industry, this type of basket is mainly used for pulp screening and is commonly referred to as wedge wire basket. As opposed to conventional wedge wire baskets, in which the profiled bars are permanently joined to the rings, the present invention allows replacing the profiled bars when required and to fully re-use the main structural elements. This is achieved with an assembly that allows to insert the profiled bars, preferably consecutively sled into each aligned ring grooves in a vertical movement. The ring grooves are profiled such that there is sufficient clearance for sliding in the profiled bars. The mounting clearance is then removed radially to hold the profiled bars in place. According to an illustrative embodiment, this is achieved by squeezing an element made of compressible material, and placed between each ring pair.
摘要翻译： 这里描述了具有可更换型材的筛篮和制造这种筛篮的方法。 筛篮包括沿圆周均匀间隔的成型条，以形成覆盖整个篮子长度的多个连续槽。 异形棒通过支撑结构固定在适当的位置，包括支撑环。 在纸浆和造纸工业中，这种篮子主要用于纸浆筛分，通常被称为楔形丝网。 与传统的楔形丝网相比，其中成型棒永久地连接到环上，本发明允许在需要时更换成型棒，并且完全重新使用主要结构元件。 这是通过一种组件实现的，该组件允许在垂直运动中将型材棒优选地连续地滑入每个对准的环形槽中。 环形槽被成形为使得在成型条中具有足够的间隙以滑动。 然后将安装间隙径向卸下，以将异形棒保持在适当的位置。 根据说明性实施例，这是通过挤压由可压缩材料制成的元件并且放置在每个环对之间来实现的。

摘要： A screening device (e.g., screen plate or screen cylinder) is manufactured relatively inexpensively and easily yet has uniform screening openings (e.g., screening slots) even when of a width of less than 0.5 mm. A plurality of wires having first and second sections (the second sections having base portions and of smaller cross-section than the first sections) are mounted substantially parallel to each other, supported by at least one support bar or ring. The bars or rings have slots formed in a first side surface, and a cavity in open communication with the slots in a second side surface. The wires are fixed to the bars or rings by deforming the wires (e.g., by bending a flap, engagement by a reciprocating tool, welding, etc.) within the cavity, or by deformation of the support bar or ring in the cavity. The screen plate or cylinder is preferably used to screen or otherwise treat a cellulose pulp suspension, e.g., by subjecting the first sections of the wires to a flow of pulp with accepts passing through the screening openings.

摘要： In a cylindrical sieve, a first frame 7 is provided with a first ring plate 7a arranged in a radial direction and a ring plate 7b extended inward in an axial direction X of the sieve from an inner end of the first ring plate 7a. The ring plate 7b has an inwardly warped end. A ring projection 2a is fit in a ring-shaped cavity K1 defined by a ring recess 10a and the first frame 7. The ring plate 7b presses the ring projection 2a inward in the radial direction to prevent the ring projection 2a from being slipped off the matching recess. Through holes 7c (counter bores) are formed in the first frame 7 along the axial direction X. Four of the through holes 7c are used to fasten the rods 6 and receive the Phillips head screws 6f seated therein, and the remaining through holes 7c receives Phillips head screws 20 (see FIG. 1) seated therein for reinforced linkage of the first frame 7 with the holder frame 11.
