UNIT FOR PUMPING AIR CONTAINING PARTICLES AND SEPARATING THE PARTICLES FROM THE AIR |
摘要 |
<p>A unit (2) for pumping air containing particles (5) and separating the particles (5) from the air comprises a housing (10) having a space (20) for receiving and storing the particles (5), and an air pumping device (30) being arranged inside the housing (10) and comprising a basic fan (31) intended for pumping air out of the particle storage space (20), and another fan (32) intended for separating the particles (5) from the air. A gap (22) is present between the fan arrangement of the air pumping device (30) and the housing (10), and in order to avoid a flow of air containing particles (5) through the gap (22), at least a major portion of the basic fan (31) is uncovered, so that a relatively strong pumping action on the basis of an interaction of an outer surface of the basic fan (31) with a stationary wall is avoided.</p> |
