Press for sewage screenings

摘要

The screen housing (4) is connected to a washing vat (1), via the worm shaft (6) and a funnel-shaped screening channel (3). The shaft in the vat has a worm-shaped washing blade (8). In the channel, this merges into a conical worm conveyor (9). The worm conveyor is connected to the cylindrical press worm (10) in the screen housing. The washing blade has a large dia. and a steep pitch. The pitch of the connected worm conveyor decreases in size. The press worm has a small dia. and a low pitch. The washing vat is formed as a screen vat (11), the inner wall of which is fitted to the OD of the cylindrical washing blade.
