Trap for collecting waste materials, e.g. material ejected by device, has separating partition with main section at less than specified angle from vertical

摘要

The trap (1) comprises a housing (2) containing a separating partition (5) which is permeable to air and dust but impermeable to waste material and which divides the housing into first (4a) and second (4b) compartments with an intake (3) and outlet respectively. The partition has a main section (5a) set at less than 30 deg to the vertical. The trap (1) comprises a housing (2) containing a separating partition (5) which is permeable to air and dust but impermeable to waste material and which divides the housing into first (4a) and second (4b) compartments with an intake (3) and outlet respectively. The partition has a main section (5a) set at less than 30 deg , preferably less that 15 deg to the vertical. The main section covers at least 50% of the partition's height (h) and is situated opposite a dust filter (13). The upper section (5b) of the partition is curved in shape to deflect the air flow over the surface of the main section.
