Mobile dust removal device

Abstract

Mobile dust extraction device (10) for separating contaminants from an airflow, in particular chips and dust, comprising at least: an air inlet (13), a filter arrangement (14) for cleaning the airflow, a fan (17) for drawing in and blowing out the airflow, an air outlet (18), at least one mobile, closed transport collection container (15) positioned below the filter arrangement, wherein at least one opening (16) is formed between the at least one transport collection container (15) and the filter arrangement, through which the separated contaminants fall into the at least one transport collection container (15), at least one seal (19) arranged around the at least one opening (16), and at least one intermediate shelf (22) which can be inserted into the dust extraction device (10).such that the at least one intermediate shelf (22) seals the at least one opening (16) to the outside by means of the at least one seal (19), wherein the intermediate shelf (22) has a chamfer (33) or rounding on at least one of its upper edges, in particular on its insertion edge, and at least one spacer plate (32) associated with the transport collection container (15), which(s) can be positioned under at least one part of the rollers of the transport collection container (15) in order to widen a gap between an upper edge of the transport collection container (15) and the seal (19) on an insertion side for the intermediate shelf (22) in a wedge shape.
