Embodiment Construction

[0038] figure 1A screen according to an embodiment of the invention is shown viewed from the end. It consists of a frame structure and a moving part suspended from it. The moving part of the screen can also be supported from below instead of being suspended. Suspension is achieved here by means of the articulated rod 3 . Instead of the articulated rod 3 , the suspension can also be realized by means of steel cables. The moving part comprises two screen modules 4 and a frame module 5 between them. The screen module 4 comprises a screen chamber or a plurality of screen chambers substantially one above the other, which are structurally separated from each other, for example by a solid intermediate layer, in each screen chamber for screening The divided material is sieved into at least two fractions. In the figures an embodiment is shown in which the screens are double-layered, in other words there are two screen chambers one above the other in each screen module 4 .

Abstract

A screen, preferably making a circular trajectory, for use for example in the wood-working industry, the screen being implemented by means of meshes having different mesh sizes and comprising a number of mesh levels (7) one above another, with which screen wood-based raw material is screened into different-sized fractions, preferably after chipping and drying, which screen comprises a frame part (1) and a moving part (2). The invention is implemented in such a way that the moving part (2) of the screen comprises at least two screen modules (4) and at least one frame module (5).This invention is especially prepared for using material of the wood-working industry and its contamination with dust after the chipping and / or drying. Therefore one of the main issues to be dealt is the prevention of damages due to dust explosions.

Description

technical field [0001] The object of the present invention is a screening element with a preferably circular trajectory, in particular for the wood processing industry, which is realized by means of nets with different mesh sizes and comprising A plurality of mesh layers through which the wood-based raw material is screened into fractions of different sizes, the screening element comprising a frame portion and a moving portion. [0002] The invention prepares in particular materials for the woodworking industry and their dust-containing contamination after cutting and / or drying. Therefore, one of the main problems to be solved is to prevent damage caused by dust explosions. [0003] Accordingly, the present invention relates to a sieving element for use in a particleboard factory, preferably with a circular movement, by means of which wood-based raw material is sieved into different fractions after cutting and drying. [0004] With this system, raw materials are screened int...
