The upstream side of the rotor 7 is formed as an upstream portion 7〇, and the downstream side is formed as a downstream_71, and the agitating 10 mixing member 7& which is provided on the outer periphery of the upstream portion 7〇 and the downstream portion 71 is inclined, which makes the agitating member 7a slightly The linear portion lower portion 7A is closer to the upper portion 7; 8 than the rotation direction of the rotor 7. The rotor is rotated by the motor (not shown) through the transmission belt 8 and the rotary shaft 9. Further, the 10 shown in Fig. 1 is attached to the sealed casing so that the water spout 10a faces the upper end surface of the rotor 7 (and the water spout l〇a faces the rotor). The center is better) the water supply path. In this way, the paper-making raw material feeds the self-made paper material supply passage 3 into the sealed casing 1, and is driven by a motor (not shown) through the transmission belt 8 and the rotary shaft 9 to rotate: when the rotor 7 rotates, the foreign matter in the papermaking material cannot pass through the sieve. The separator is stored in the mA of the first chamber, and the papermaking material passing through the filter 2 is guided to the outside of the sealed casing through the second chamber 20 1B and the selective paper raw material discharge passage 4. Further, in the middle of the filter 2, the paper-making raw material flowing to the downstream side is hindered by the dilution water guided by the self-dilution water to guide the nR1, so that the separation effect between the foreign matter and the good fiber in the papermaking raw material can be improved, and The dilution water dilutes the papermaking original 11 200813294 which has been increased in concentration on the upstream side through the filter 2, thereby improving the separation effect of the fine fiber, and further, the impact in the papermaking material is set on the side of the ring facing the rotor 7 The undissolved film of the convex portion RT can reflow to the upstream side of the papermaking raw material, thereby further improving the separation effect between the foreign matter and the good fiber in the papermaking raw material. Further, in the downstream side of the filter 2 in the first chamber 1A, the water spout 1〇a of the first water supply passage 10 interposed in the sealed casing 1 faces the upper end surface 7T of the rotor 7, so that the impact The water on the upper end surface 7 of the rotor 7 flows in a slightly horizontal direction, and exhibits an effect of hindering the flow of the paper-making material from the upper opening portion 2 of the filter 2 to the foreign matter discharge port lc, in other words, the blockage is refused to exert the foreign matter. The fiber exiting the lc side of the row 1 is pushed back to the upstream side of the chamber ia, which can improve the separation effect between the foreign matter and the good fiber in the papermaking raw material. In addition, by providing a valve in the passage that is opened and closed in the foreign matter discharge passage 5 and the weight foreign matter discharge passage 6, the valve can be opened and closed, and the valve can be stored in the third chamber by adjusting the degree of opening of the valve or appropriately opening and closing the adjustment. The foreign matter in the 丨8 leads to the outside of the closed box 1. Further, in the above-described embodiment, the end portion of the lower portion 7A of the agitating member 7a on the downstream side is extended to a position facing the introduction port R1 (see the figure), but the present invention is not limited thereto, and may be as As shown in Fig. 6, the portion of the transfer member 7a facing the introduction port is removed. In addition, although the upper end surface 7T of the rotor 7 is a flat surface (see the figure), the present month is not limited thereto, and the protrusion (removing the blade) 7Z may be provided as shown in the drawing of the brothers 6 to 8. The centrifugal force of the (stirring blade) 72 changes the flow direction of the water from the water spout 10a to the horizontal direction to further enhance the rejection effect. The arrow shown in Fig. 7 represents the direction of rotation of the rotor 7. 12 200813294 Further, as shown in Fig. 9, a flow guiding portion G may be provided around the water spouting port 10a so that the surface of the flow guiding portion G faces the upper end surface 7T of the rotor 7 to guide the water from the water spout 10a. The water from the water spout l〇a is brought close to the protrusion (stirring blade) 7Z. Further, in FIG. 5, the opening width W of the ring portion R of the concave portion RO in the circumferential direction is smaller than the flat surface length L of the ring portion R of the convex portion RT in the circumferential direction, but the present invention is not limited thereto. Alternatively, as shown in Fig. 10, the opening width W of the ring portion R of the concave portion RO in the circumferential direction may be made larger than the flat surface length L of the ring portion R of the convex portion RT in the circumferential direction. Further, in the above-described embodiment, although the convex portion RT protruding from the surface of the filter 2 is provided on the side of the ring portion R facing the rotor 7, the present invention is not limited thereto, and may be the same as the 11th and 12th. As shown in the figure, the convex portion RT of the uneven portion on the side of the ring portion R facing the rotor 7 does not protrude from the surface of the screen 2. The screening apparatus of Figs. 11 and 12, except that the convex portion RT does not protrude from the surface (inner wall) of the filter 2, is the same as that shown in Fig. 3 to Fig. 5, and therefore for the 11th and 12th drawings. The same components as those shown in Figs. 3 to 5 are denoted by the same reference numerals, and the description thereof will be omitted. In other words, the front end portion X of the convex portion RT having the uneven portion and the vertical portion of the sealed case 1 are located at a position lower than the position 20 at which the convex portion is lower than the front end portion X. Y, and is inclined such that the front end portion X of the convex portion RT is closer to the end portion γ than the convex portion after the rotation direction of the rotor 7 is the same as the convex portion (see the arrow direction shown in Fig. 12(b)]. Further, the concave portion 110 is located between the adjacent convex portions RT, and the convex portion RT and the concave portion RO are respectively formed plurally on the ring portion. 13 200813294 The convex portion RT shown in Figs. 11 and 12 is the same as the convex portion RT shown in Figs. 3 to 5, and the undissolved sheet of the impact convex portion RT in the papermaking material is dissociated, and is subjected to the raw material for papermaking. The effect of reflux on the upstream side can improve the separation effect between the foreign matter and the good fiber in the papermaking raw material. 5 [Brief Description] Fig. 1 is a schematic cross-sectional view showing a screening apparatus according to an embodiment of the present invention.
