The utility model realizes by the following technical solutions: Efficient air flow grader, comprises at least Liang Ge separation chamber, and described multiple separation chamber are serially connected from top to bottom successively.Wherein, meal outlet (10) of previous separation chamber (1) connects with the charging aperture (20) of a rear separation chamber (2), and fine powder outlet (3) of each separation chamber all connects or is connected in fine powder blanking lock airduct (4) respectively.
Further, described separation chamber comprises casing, and casing is divided into airflow chamber and bottom air chamber by funnel-form dispersion plate (6); Water conservancy diversion adjustable plate (5) is set in airflow chamber, funnel-form dispersion plate (6) bottom sets out hopper (8), blow tank (8) exports (10) and connects with meal, bottom air chamber is divided into the first air chamber (7) and the second air chamber (9) by described blow tank (8).Described water conservancy diversion adjustable plate (5) is arranged on separator charging aperture lower end.
Further, described separator fine powder outlet (3) place is also provided with fine powder discharging adjusting device (30), to regulate the load of fine powder.
Further, for increasing separating effect, described separator is also provided with powder pretreatment unit (11), powder pretreatment unit (11) is arranged on separator gating location place topmost, and powder pretreatment unit (11) can be disintegrating apparatus or material pre-separate device or the combination of the two.For convenience of the maintaining in later stage, powder pretreatment unit (11) side is also provided with the stair bearing (11a) of maintenance.
Compared with prior art, the utility model has following beneficial effect:
1. the utility model only carries out a sorting for separator in the past, the situation that separating effect is undesirable, devise multipass sort room, the meal discharging opening of previous stage is connected with the charging aperture of next stage, the fine powder discharging opening of each grade of separation chamber is connected in fine powder blanking lock airduct jointly or respectively, by the structure of multistage-combination, the fine powder thoroughly do not sub-elected by upper level is separated further, and meal carries out further sorting.Through field trial, powder net efficiency is up to 99%.
2. designed by multilevel hierarchy, thoroughly can be separated fine powder, avoid in prior art the situation of the fine powder that adulterates in meal after separator sorting, certainly it also avoid a large amount of fine powders and meal to mix to come back to and extrude or repeat in disintegrating apparatus situation that is broken or that extrude, reduce further disintegrating apparatus and repeat acting, reduce the energy consumption of grinder equipment, reduce production cost.
