The device according to the invention serves for classifying or concentrating liquids laden with fibers or solids by means of screening or filtration. For this purpose, a cylindrical fine screen is arranged in a vertical position in a housing comprising an axially cylindrical vibrator being somewhat smaller than the fine screen so as to produce an annular gap between the screen and the vibrator. In the vibrator, there is a vibration motor with imbalances, which generates circular horizontal oscillations. The liquid to be treated is introduced into the annular gap, primarily from above, and the concentrated liquid is removed at the bottom. The cleaned liquid is discharged between the screen and the wall of the housing. The feature of the invention is that the vibrator is mounted on at least three rubber elements which primarily allow the vibrator to perform a circular horizontal movement. However, by allowing the vibrator to move away vertically, these rubber elements also compensate for occurring vertical forces caused by unsymmetrical loads on the screen.
An apparatus for classifying or concentrating a liquid laden with fibers or solids by means of screening or filtration by using a cylindrical fine screen having hole-shaped or slot-shaped openings, said screen being fixedly clamped in a housing in a vertical position, in the interior of which an axially cylindrical vibrator is arranged, in a manner forming an annular gap, in which a vibration motor is disposed, which performs circular horizontal oscillations, and in which the liquid to be treated is introduced at one side of the annular gap and the classified or concentrated liquid is removed from the opposite side and the cleaned liquid or the liquid provided with fine particles is discharged between the screen and the housing wall, characterized in that the vibration unit is connected to the housing such that a vertical mobility is enabled in addition to the horizontal mobility, wherein the horizontal and vertical mobility of the vibration unit is assumed by at least three rubber buffers.
