The dynamic and static combined efficient powder concentrator is used as a sorting device and is widely applied to industries such as building materials, electric power, steel and the like. The separation structure of dynamic-static combined high-efficiency powder separator is formed from dynamic rotor whose inner side can be rotated and static blade device whose outer side is fixed, the material to be separated can be pneumatically or mechanically conveyed to the powder separator, and the air flow can be fed into the powder separator together with material or fed into the powder separator by means of another inlet. The air current that carries the material firstly gets into and lies in the fixed stator blade in the outside, and the stator blade generally is certain angle with radially, and the purpose is the direction that changes the air current, and makes partly thicker granule touch the stator blade and lose kinetic energy and fall in the collection device below, reaches the effect that the one-level was selected separately. The direction of the airflow is changed and the airflow carrying the materials continuously enters the rotating dynamic rotor, the particles meeting the fineness requirement enter the rotor and are collected by subsequent equipment to be used as finished products, and the particles not meeting the fineness requirement fall into a collecting device below for subsequent treatment.
According to production requirements, the same high-efficiency powder concentrator is often used for separating different materials at different stages, such as cement raw materials or cement with different material proportions. In general, the adjustment of the rotational speed of the dynamic rotor is a common treatment method, but the influence of the clearance and angle between the stationary blades on the separation efficiency and the system resistance is not negligible. Because of the different fineness and density of the materials, the sorting concentration and the wind speed requirements are different. If the rotating speed of the dynamic rotor is adjusted and the adjustment of the gap or the angle between the static blades is neglected when different materials are sorted, the resistance of the powder concentrator is easily improved, the energy conservation and the consumption reduction are not facilitated, and the productivity of the powder concentrator is also influenced in serious cases.
The prior art widely adopts a manually adjustable stationary blade structure, and manually adjusts the gap and angle of the stationary blade in a shutdown state. However, this is labor and time consuming, and the actual effect and theoretical calculation may be different, and it is likely that one adjustment cannot be made.
