PCT No. PCT/SE87/00504 Sec. 371 Date May 3, 1989 Sec. 102(e) Date May 3, 1989 PCT Filed Oct. 29, 1987 PCT Pub. No. WO88/03611 PCT Pub. Date May 19, 1988.An arrangement for an inlet and an outlet in a rotating drum sieve for the separation of solid particles from a liquid mixed with particles in which a drum sieve comprises a drum casing provided with a sieve opening and a feed screw situated internally within the drum and is arranged for the supply of a liquid mixed with particles to the internal space of the drum and for the removal of sieved material from the internal space of the drum. The invention permits, amongst other things, a simple design for the sieve drum and the even and effective supply of liquid mixed with particles to the drum sieve, as well as effective and simple discharge of the drained material from the internal space of the drum. The inlet and the outlet are formed each by its own part of a commonly rotating pipe situated internally within the drum and extending through the entire drum, which pipe exhibits a number of supply openings distributed along the longitudinal sense of the pipe and displaced in relation to one another around the circumference of the pipe for the purpose of supplying a liquid mixed with particles to the internal receiving space of the drum, at the same time as the drum and the pipe are caused to rotate. A shovel-like lifting device is attached to the outlet and of the feed screw to transport sieved particles to the pipe outlet. |
