Abstract
It is developed a Γ-shaped inertial dust collector which contains alternately located of jalousie separator and countercurrent separator for the separation of light impurities from the exhaust air. The initial section of the jalousie separator is horizontal, the final section is vertical. It is proposed the technique allows calculating the effect of light impurities separation from the exhaust air by the dust collector quite accurately depending on its design parameters and fractional composition of grain dust particles. The dust collector which has a height of inlet branch pipe Ho = 0.16 m, the angle of the jalousie grate α = 7°, the angle of the jalousie in the grate β = 30°, a height of the outlet of the jalousie separator hj = 0.04 m, a height of the outlet of the countercurrent separator hc = 0.04 m, a length jalousie grate L = 1.0 m, the height of the camera for dust precipitation H = 0.6 m is installed in the air system of seed cleaning machine that functioned on seed cleaning of barley variety Abava. The effect of the separating of light impurities from the exhaust air by the air system was an average value Eo = 98.9%.
