    • A solid, fiberglass-reinforced plastic rotary drum filter includes a first solid fiberglass-reinforced head at one end and a second solid fiberglass-reinforced head at the other end. A central solid fiberglass-reinforced plastic pipe extends from one plastic head a predetermined distance into the plastic drum. A plurality of radial, solid fiberglass-reinforced plastic drainage conduits extends from the solid fiberglass-reinforced plastic deck of the plastic drum to the central pipe. The longitudinal separation between the radial plastic drainage conduits and the first plastic head is carefully chosen and the dimensions of the first plastic head are such that the first plastic head is strong enough to withstand the head-bending force due to radial force, drive torque, and hydraulic end force.
    • 固体，玻璃纤维增​​强塑料旋转鼓过滤器包括在一端的第一实心玻璃纤维增​​强头和另一端的第二实心玻璃纤维增​​强头。 中心实心玻璃纤维增​​强塑料管从一个塑料头延伸一预定距离进入塑料桶。 多个径向，实心的玻璃纤维增​​强塑料排水导管从塑料桶的实心玻璃纤维增​​强塑料甲板延伸到中心管。 仔细选择径向塑料排水导管和第一塑料头之间的纵向间隔，第一塑料头的尺寸使得第一塑料头足够坚固以承受由于径向力，驱动扭矩等引起的头部弯曲力， 和液压端力。

    • An endless screen extends around an upper roller, above the stream of a ditch or the like, and a lower roller, submerged in the stream. A cleaning brush engages the underside of the lower reach of the screen, the brush rotating in a direction opposite to the movement of the screen, while a roller or rod supports the screen just below the brush. The brush may be driven directly from a motor and speed reducer, with a belt drive to an upper pulley producing further speed reduction, or a speed reduction drive between the motor and the brush with a belt or chain drive to the upper roller may be utilized.The lower roller for the screen has a fixed center surmounted by a plastic or rubber bushing about which a cylinder of the lower roller rotates.A weir directs water onto the screen, the weir including a transverse partition mounted in the ditch and having a rectangular slot therein. A rectangular funnel occupies the slot, having a base member extending to the screen and side members extending to side plates mounted on bars of a frame, with the forwardly extending members inside the plates.
    • 环形屏幕围绕上部辊子，在沟槽等的上方延伸，并且下部辊子淹没在流中。 清洁刷接合屏幕下方的下侧，刷子沿与屏幕移动相反的方向旋转，而辊或杆支撑在刷子正下方的屏幕。 刷子可以直接从马达和减速器驱动，带式驱动器可以进一步降低上皮带轮，或者可以利用皮带或链条驱动到上辊的马达和刷子之间的减速驱动。 。

    • 1,045,580. Forming pulp sheets. IMPROVED MACHINERY INC. Jan. 8, 1965 [Jan. 20,1964], No. 893/65. Heading D2A. [Also in Division B1] A cylinder mould for separating wood pulp from its filtrate and forming a pulp sheet comprises a drum portion 12, imperforate ribs 22 mounted thereon and extending in an axial direction to form compartments between adjacent ribs 22, cover elements 40 extending arcuately over the greater portion of each compartment but leaving a gap 42, means - for example a wire 44 of rectangular cross-section spirally wound about the drum - on elements 40 to form a plurality of peripherally extending grooves, and a sheet filter 50. Cover elements 40 are upturned at one end 48 which has notches through which wire 44 passes, end 48 dividing each groove into separate sections. In use the mould is rotatably mounted in a vat and has a stationarily mounted valve element 16, Fig. 1 (not shown) extending around the mould either at the middle or at one end. The compartments between ribs 22 have holes in the end adjacent element 16 to be in communication therewith. Over the greater arcuate portion of the mould, element 16 is connected to a source of suction through the centre of the mould so that suction is applied to the inside of screen 50, and over the remaining arcuate portion of the mould valve element 16 is connected to the atmosphere, so that the pulp can be removed from the mould.
    • 1,045,580。 形成纸浆。 改进机械有限公司1965年1月8日[1月 20,1964]，第893/65号。 标题D2A。 [也在B1部分]用于从其滤液中分离木浆并形成纸浆片的圆筒模具包括鼓部分12，安装在其上并在轴向方向上延伸的无孔肋条22，以在相邻肋条22之间形成隔间，覆盖元件40延伸 在每个隔室的大部分上弧形地，但留下间隙42，意味着例如围绕鼓螺旋地缠绕在元件40上的矩形横截面的线44，以形成多个周向延伸的凹槽和片状过滤器50。 盖元件40在一端48上翻转，端部48具有通过该导线44穿过的凹口，端部48将每个凹槽划分成单独的部分。 在使用中，模具可旋转地安装在大桶中，并且具有静止安装的阀元件16， 1（未示出）在模具的中间或一端延伸。 肋22之间的隔间在邻近元件16的端部具有与其连通的孔。 在模具的较大弓形部分上，元件16通过模具的中心连接到抽吸源，使得抽吸被施加到筛网50的内部，并且在模具阀元件16的剩余弧形部分上方连接 到大气中，使得纸浆可以从模具中去除。
