Abstract

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.

Abstract

The device according to the invention serves for classifying or concentrating liquids laden with fibres or solids by means of screening or filtration. For this purpose, a fine cylindrical screen is arranged in a vertical position in a housing containing an axially cylindrical vibrator that is 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 unbalance weights, 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 drawn off 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 vertical forces occurring, which may be caused by unsymmetrical loads on the screen.

Abstract

A plant for generating biogas from organic biodegradable material containing liquid and solid components, such as waste products, in particular liquid manure from agricultural enterprises, comprises a biogas generation container (9) having a feed for the degradable material and a biogas collection zone (6) having a biogas outlet, and a flotation separation unit having a microbubble generation unit (15) for separating off the solid components from the liquid components of the degradable material. The flotation separation unit comprises a chamber region (14) which is delimited in the interior of the biogas generation container and essentially active in the direction of gravity and having a closed bottom and an open upper end arranged below the liquid level of the biogas generation container. Clarified liquid from the chamber region and a gas, in particular the biogas from the biogas collection region, can be fed to the microbubble generation unit for charging the liquid with gas. The outlet of the microbubble generation unit is connected to an inlet (18) of the chamber region in order to recycle microbubble-forming clarified liquid to the chamber region. Near the bottom of the chamber region, an outlet (116) for clarified liquid from the chamber region is provided. The flotation separation takes place in the chamber region in countercurrent flow to the ascending microbubbles.
