Device for cleaning the air coming out of cement bins during loading and venting to the atmosphere during the emptying operation. The device is comprised of a cylinder (1) slit at its center and at its upper end (3), a rubber sleeve (2) inside the cylinder, the assembly being clamped by a collar (4). The air passes into the sleeve and presses the sleeve against the cylinder thereby obstructing the orifices (6). The air laden with cement settles in water (5). During emptying, the vacuum created in the tube detaches the sleeve and allows air to come in. The device according to the invention is particularly intended to air purification during the filling of cement bins. |
