阅读说明：本技术 筛装置 (Screen device ) 是由 M·赖因斯坦 J·莱曼 T·米克拉特 于 2019-07-01 设计创作，主要内容包括：本发明描述了一种筛装置,该筛装置优选地以筛篮的形式来设计。这种的筛装置例如被应用于造纸行业中的分类过程中。在相邻的截面被成型的筛杆之间分别形成了筛间隙或筛缝隙。所述筛杆在其脚部区域处被容纳在支承元件的、与脚部区域几何结构相匹配的容纳凹口中,并且被持久地紧固在该容纳凹口中处。在此,所述型材杆这样地来布置：在相邻的型材杆的之间的恒定的间隙宽度时,沿着筛篮轴线方向,轮廓深度从材料流入侧开始向筛渣出口侧而增加,并且所述筛装置的直径在材料流入侧上比在筛渣出口侧上更大。(The invention describes a screen device, which is preferably designed in the form of a screen basket. Such screen arrangements are used, for example, in sorting processes in the paper industry. Screen gaps or screen slots are formed between adjacent profiled screen bars, respectively. The sieve bars are accommodated in the foot region of the support element in a receiving recess, which is adapted to the geometry of the foot region, and are permanently fastened in the receiving recess. The profile rod is arranged here in such a way that: at a constant gap width between adjacent profile rods, the profile depth increases in the direction of the basket axis from the material inflow side to the reject outlet side, and the diameter of the screen device is greater on the material inflow side than on the reject outlet side.)

1. Screen device, preferably in the form of a screen basket, with screen gaps or screen slots formed between screen bars (4, 4 ') shaped in cross-section, wherein the screen bars (4, 4 ') are received in receiving recesses of a support element matching the geometry of the foot region at the foot region thereof and are permanently fastened thereto, characterized in that the profile bars (4, 4 ') are arranged in such a way that: with a constant gap width (w) between adjacent profile bars (4, 4'), the profile depth (t 1, t 2) increases in the basket axis direction from the material inflow side (2) to the reject outlet side (3), and the diameter of the screen device (1) is greater at the material inflow side (2) than at the reject outlet side (3).

2. Screen device according to claim 1, characterized in that the profile depth (t 1, t 2) increases continuously from the material inflow side (2) to the reject outlet side (3).

3. Screen device according to claim 1, characterized in that the profile depth (t 1, t 2) increases stepwise starting from the material inflow side (2) towards the reject outlet side (3).

4. A screen arrangement as claimed in any one of the preceding claims, characterised in that the screen bars (4, 4') are oriented axially with respect to the screen basket axis.

5. A screen arrangement as claimed in any one of the preceding claims 1 to 3, characterized in that the screen bars (4, 4') are configured linearly obliquely with respect to the screen basket axis.

6. The screen apparatus as claimed in any of claims 1 to 3, characterised in that the screen rods (4, 4') are oriented discontinuously curvedly with respect to the screen basket axis.

7. The screen device according to any one of the preceding claims, characterized in that the profile bars (4, 4') have a substantially triangular prevalent profile.

8. The screen apparatus as claimed in any one of the preceding claims, characterized in that the gap width (w) is in the range of 0.05 to 0.8mm, preferably in the range of 0.1 to 0.4 mm.

9. The screen apparatus of any one of the preceding claims, wherein the profile bar width (b 1, b 2) is in the range of 2.0mm to 8mm, preferably in the range of 2.0mm to 4.0 mm.
