Description of the Related Art A multi-plate type filtering apparatus in which filter tubes each having an alternately superposed array of fixed plates and movable plates are vertically arranged, treats raw water from the entire periphery of each opening edge of the multi-plate in accordance with the supply pressure. Guide the water evenly into the filtration gap and squeeze out moisture toward the outer periphery.
The separation has the advantage that the entire filter tube material can be used evenly.
There is one described in JP 8805. This known vertical arrangement-multi-plate type filtration device is configured such that a number of fixed filtration plates having a circular opening and a number of movable filtration plates having a smaller diameter than the circular opening are alternately superposed and arranged vertically, and By providing a pressing roller that rotates in sliding contact with the opening edge of the fixed filter plate aligned in the hollow portion, the movable filter plate is swung to substantially slide with the fixed filter plate,
The gap between the filtration plates is always regenerated.

Is kneaded by a pressing roller, which rotates inside the hollow portion and is sufficiently narrower than the opening diameter of the filter plate, so that the viscosity tends to be rather high and the state is difficult to be separated. The kneaded liquid to be filtered is not water separated from the kneaded liquid, but the liquid itself is pushed into the filtration gap between the filter plates by the pressing roller, and the liquid discharged from the outer peripheral edge is a satisfactory separated filtrate. However, they have the drawback that they are suspended, resulting in poor recovery and poor filtration.

The shaft cam is driven by a cam so as to be at least in a swinging state, and the swinging center axis of the aligned opening row is aligned with the opening row center axis of the fixed plate. D) The fixed plate And idle The lower end of the hollow portion composed of the synthetic aperture row is connected to the inlet pipe of the treated raw water, the upper end is connected to the outlet pipe of the concentrated water, and the combined outer peripheral portion of the two plates that is the outer peripheral end of the filtration gap is used for drainage.

In this case, the fixing plate 11 is an equilateral triangle with the apex cut off, and three sides of the corner end after the cut are circumscribed to the spacer 12. All fixed plates 11
Are aligned in the axial direction, and the shape thereof is defined by a curved wave that oscillates around the concentric circumferential base line (not shown) within the main body triangle (not shown) and that goes around the circumference of the circumference, that is, a closed wave-shaped curve. It was made. From the aligned outer edges of the fixed plate 11, that is, three intermediate portions, three portions of the floating plate 13 in which the wave-shaped opening edges 13a are aligned project outward with symmetry. The projecting portion of the floating plate 13 is for receiving the following cam drive, and if the fixed plate 11 is, for example, a square, it becomes four places from its four sides or the contour shape of the fixed plate 11. May be variously changed so that three or more portions protrude asymmetrically. After all, in order to drive the floating plate 13 stably, it is sufficient that the floating plate 13 protrudes from at least three places over a wider range than 180 ° around the central axis of the fixed plate 11 and is cam-driven.

Are eccentrically rotated at respective positions corresponding to three protruding outer peripheral edges of the floating plate 13, and are always in contact with the outer peripheral edges to drive the cam. Therefore, the eccentric shaft cam 17
The drive shaft shafts 17a are arranged axially symmetrically with respect to the center position of the fixed plate 11, and by making the eccentric angles of the cams 17 equal at each moment when they are rotated at the same speed in the same direction, each floating The plate 13 is eccentrically swung,
The center axis of the swing of the outer periphery and the aligned opening edge 13a is aligned with the fixing plate 11, that is, the center axis of the opening 11a. At this time, not only the cam drive by the eccentric shaft cam 17 but also the frictional drive causes the outer peripheral edge of each floating plate 13 to rotate (rotate), and thus involves the aforementioned eccentric rotational swing and rotation.

a is slightly smaller than the average diameter of the opening edge 11a of the fixing plate 11, and in the state shown in FIG. 2, since the three eccentric shaft cams 17 are at the right eccentric position in the drawing, the opening edge 13
The right side of "a" substantially coincides with the right side of the opening edge 11a of the fixing plate 11, and the left side of the opening edge 13a is located at a position inward of the left side of the opening edge 11a of the fixing plate 11.
Since the average diameter difference between the two plates 11 and 13 and the amplitude of each eccentric shaft cam 17 are matched, when the three eccentric shaft cams 17 reach the left eccentric position in the figure, the left side of the opening edge 13a is left. The portion substantially coincides with the left side of the opening edge 11a of the fixing plate 11, and the right side of the opening edge 13a is
Of the opening edge 11a. Therefore, the line-of-sight opening of the synthetic opening row forming the hollow portion 7 of the multi-plate filtration mechanism swings with the row of the opening edge 13 a of the floating plate 13.

In these two embodiments, the amplitude of the eccentric shaft cam is set to
Depending on the purpose, it is also possible to make the average diameter of the opening edge 11a and the opening edge 13a of both plates equal to each other, or to make the average diameter difference larger than the average diameter difference of 3a.
