    • A sifter frame comprises an outer frame (6) and an inner frame (5). The outer frame (6) is formed from frame members (62 - 64) having the same height and includes a pair of fine powder dropping ports (75), a rough powder dropping port (69) and a rectangular fine powder receiving plate (67) disposed in a region surrounded by these openings and one of the outer block frame members (62). The inner frame (5) is fitted within the space above the receiving plate (67). The two outer frame members (54, 55) of the inner frame (5) in contact with the fine powder dropping ports (65) project towards the rough powder dropping port and beyond the outer block frame member (52) of the inner frame (5) in contact with the rough powder dropping port (69) to form horn portions. The outer frame (6) includes complementary receiving portions (82) for receiving and engaging the horn portions of the inner frame (5).
      The engaging surfaces of the horn portions and the receiving portions are formed with mutual sealing surfaces having an arcuate shape, so that a vertical compression force applied to the engaging surfaces via the upper stage sifter provides a sealing effect.
    • 筛子框架包括外框架(6)和内框架(5)。 外框架(6)由具有相同高度的框架构件(62-64)形成,并且包括一对细粉末滴入口(75),粗粉末滴入口(69)和矩形细粉末接收板(67) )设置在由这些开口包围的区域中,以及一个外框架构件(62)。 内框架(5)装配在接收板(67)上方的空间内。 内部框架(5)的与细粉末滴入口(65)接触的两个外框架构件(54,55)朝向粗粉末滴落口突出并且超出内框架的外框架构件(52) 5)与粗粉末滴入口(69)接触以形成喇叭部分。 外框架(6)包括用于接收和接合内框架(5)的喇叭部分的互补的接收部分(82)。 喇叭部分和接收部分的接合表面形成有具有弓形形状的相互密封表面,使得通过上层筛分器施加到接合表面的垂直压缩力提供了密封效果。
