    • A dedusting apparatus for cleaning contaminates from particulate material, comprising:
      a cylindrical housing (12); a feed hopper (21)supported on said housing and terminating in a product inlet opening, said feed hopper being mounted on said housing for vertical movement relative thereto;
      an air supply apparatus supported by said housing at a lower portion to provide a flow of air into said housing; an inverted conical wash deck (30) mounted on said housing and having an apex (31) positioned centrally within said product inlet opening to receive particulate material therefrom, said wash deck including a top surface (32) formed with a plurality of apertures (33) for the passage of air through said wash deck, the vertical movement of said feed hopper changing the dimensions of a gap (39)separating said product inlet opening (111) from said conical wash deck (30) such that the rate of flow of particulate material over said conical wash deck (30) can be selectively controlled; and an air discharge collector (15) mounted above said conical wash deck (30) for collecting air passing through said wash deck apertures, said air discharge collector (15) including an annular chamber surrounding a central opening in said air discharge collector to collect air moving upwardly from said wash deck into said central opening.
    • 一种用于清洁颗粒物质污染物的除尘装置,包括:一个圆柱形外壳(12); 进料斗(21),其支撑在所述壳体上并终止于产品入口开口,所述进料斗安装在所述壳体上以相对于所述壳体垂直移动; 由所述外壳在下部支撑的空气供应设备,以提供空气流入所述外壳; 一个安装在所述壳体上并具有一个位于所述产品入口开口中央的顶点(31)的倒锥形洗涤平台(30),以从其接收颗粒材料,所述洗涤平台包括形成有多个孔(33)的顶表面(32) )以使空气通过所述洗涤平台,所述进料斗的竖直运动改变将所述产品入口开口(111)与所述圆锥形洗涤平台(30)分开的间隙(39)的尺寸,使得 可以选择性地控制所述圆锥形洗涤台(30)上的颗粒材料; 和一个安装在所述圆锥形洗涤台(30)上方的空气排放收集器(15),用于收集通过所述洗涤台孔的空气,所述空气排放收集器(15)包括环绕所述空气排放收集器中的中央开口的环形室, 从所述洗涤平台向上移动到所述中央开口中。
