    • Within a chamber having an inlet for admitting a sludgy substance for dewatering and an outlet for discharging the dewatered cake of the sludgy substance, there are disposed two laterally opposed filtration trains each consisting of a plurality of rotary filter elements which are each formed of a multiplicity of circular plates arranged face to face in the axial direction at fixed intervals and which are so disposed that they intermesh so as to permit the circular plates of each rotary filter element to partially enter the corresponding spaces between the circular plates of the adjacent rotary filter elements. The two trains of rotary filter elements are disposed opposite each other so that when a sludgy substance is introduced through the inlet and is then caused to advance through the passage intervening between the two opposed trains of rotary filter elements toward the outlet, it is gradually freed from the water component by virtue of the spaces formed in the enmeshed portions of the multiplicity of circular plates of the rotary filter elements arranged as described above, with the result that the dewatered cake of the sludgy substance is concentrated to a gradually higher degree.

    • PROBLEM TO BE SOLVED: To dehydrate and concentrate sludge by noncmpression and to dehydrate the concentrated sludge by compression to subject the dehydrated sludge to compressing dehydration in an ideal state. SOLUTION: A lot of disks 12 are fixed to a rotating axis 14 leaving a space larger than the thickness of the disk in the axial direction between then to form a rotary filter element 11. A plurality of the rotary filter elements 11 are grouped into three first, second and third contact rows A. B, C in which in the rotary filter elements adjacent to each other back and forth, a part of the peripheral edge of the disk is made to break into between the disk of the opposite rotary filter element. The dehydrator consists of the contact rows A, B, C and a treating chamber 20. The third contact row C moves sludge fed from a feeding port 21 toward a discharging port 22, and during this time, water of the sludge that has flowed in between the disk is discharged outside the treating chamber to concentrate the sludge. The first and second contact rows A, B receive the concentrated sludge from the third contact row C and move the concentrated sludge toward the discharging port 22. During this time, the concentrated sludge is compressed from above and below to discharge water of the concentrated sludge that has flowed in between the disk to outside the treating chamber. The rotational speed of the rotary filter elements of the third contact row is made higher than that of the rotary filter element of the first and second contact rows.

    • PURPOSE: To make it possible to surely execute air blow with a small amt. of compressed air to be used even if the width of a rolled stock changes by disposing plural pieces of air nozzle means in an air draining chamber movably laterally backward in the transverse direction of the rolled stock. CONSTITUTION: One piece of a screw shaft 11 is horizontally installed in the transverse direction of the chambers (transverse direction of the rolled stock 1) on the upper part of an air draining chamber of the degreasing and washing device arranged with the degreasing chamber, rinsing chamber, air draining chamber and drying chamber successively in series around the traveling rolled stock 1. The screw threads 11a inscribed in the left half part of the screw shaft 1 and the screw threads 11b inscribed in the right half part are the screw threads reverse from each other. Pedestals 18a, 18b which are screwed with the screw threads 11a, 11b move in the directions reverse from each other on the screw shaft 11 when the screw shaft 11 is rotated forward and backward by operation of a handwheel 11c. Annular cylindrical bodies 13A, 13B which are mounted at the pedestal 18, are disposed with air nozzles 17a, 17b and are fitted onto a sliding shaft 12 are moved in the directions reverse from each other in correspondence thereto.

    • PURPOSE:To count the fine particles automatically and in a short time by counting the number of time particles image-picked up by an optical microscope to obtain the integrated number of these particles and then calculating the number of fine particles for each passed liquid quantity from said integrated number, the filter are and the quantity of liquid passed through a filter. CONSTITUTION:For such an optical microscope that has a focal point formed on the surface of a filter, the space (Z1) is obtained between the surface of the filter and an objective lens together with the space (Zn) between the filter surface and the objective lens where the focal point of the lens is distanct enough away from the filter surface and therefore the image pickup is impossible to the fine particle. The distance between spaces Z1 and Zn is divided equally into (n-1) sections. The areas of measurement of the filter surface are set on the intersecting points of a checker pattern. Therefore the 3-dimensional space coordinates including the areas of surface measurement and sections are obtained at each point. The fine particles of each section are measured at each area of surface measurement, and the number of fine particles are integrated over all sections. A count arithmetic part 32 measures the sizes and number of particles from the images of particles image-picked up by a TV camera 12. The results of counting of all sections of measurements are integrated. Then N (number of fine particles)=(total number of fine particles).S/(A.F) is calculted for each quantity of passed liquid from the quantity F of the liquid passed through the filter, the filter area S an the measurement area A.
    • 目的:通过计算通过光学显微镜拍摄的粒子数量,自动计算微粒,得到这些粒子的一体数,然后计算每个通过的液体量的细颗粒数 所述积分数,过滤器和通过过滤器的液体量。 构成:对于在过滤器表面形成有焦点的这种光学显微镜,在过滤器表面和物镜之间获得空间(Z1)与过滤器表面和过滤器表面之间的空间(Zn) 透镜的焦点远离滤光片表面远离透镜,因此对于微细颗粒是不可能的。 空间Z1和Zn之间的距离被均等地划分为(n-1)个部分。 过滤表面的测量区域设置在检验图案的交叉点上。 因此,在每个点获得包括表面测量和截面面积的三维空间坐标。 在每个表面测量区域测量每个部分的细颗粒,并且在所有部分上均匀地形成细颗粒数。 计数算术部分32测量由TV摄像机12拍摄的粒子的图像的粒子的大小和数量。所有测量部分的计数结果被整合。 然后,N(细颗粒数)=(总细微粒数),从通过过滤器的液体量F中的每个通过液体中计算出S /(AF),过滤面积S为测量面积 一个。
