Embodiment Construction

[0041] Before describing the preferred way of implementing the invention with the aid of FIGS. 2 to 7, it is first discussed Figures 1a to 1d In order to better understand the present invention, the prior art is presented.

[0042] Figure 1a A vertical section in the longitudinal direction of the fuselage 3 of a vibratory screening machine 5 is shown, as it is currently used in an asphalt mixing installation above a hot mineral silo. As can be seen, in the fuselage 3, a plurality of screen inserts 1 are stacked up and down and successively arranged, so that they form six screen panels stacked up and down in the fuselage 3, and their mesh sizes are from top to bottom. down to zoom out. The individual sieve inserts 1 of each sieve panel are each fastened to a tie rod 2 (also called intermediate tie rod) in the middle region of the body 3 and in the region of the inlet side 6 and outlet side 7 of the vibrating screen machine 5 A crossbeam 8 is tensioned respectively against a...

Abstract

The invention relates to a vibrating screen machine (5) for asphalt mixing installations, comprising mesh inserts (1a, 1b) that are fixed to tension bars (2) in the centre of the machine. In order to fix the respective mesh insert (1a, 1b), both the mesh insert (1a, 1b) and the respective tension bars (2) have tubular sections (14, 16) that are successively alternately arranged along a common axis (Y), and are penetrated by a coupling rod (17) in such a way that the mesh insert (1a, 1b) and the tension bar (2) are interconnected in a positively locking manner in the mesh tensioning direction (S) and in both directions perpendicular thereto. If the positively locked connection is broken, the coupling rod (17) can be axially removed from the tubular sections (14, 16). In this way, the invention enables mesh inserts (1a, 1b) to be replaced in a simple and rapid manner compared to those of prior art.

Description

technical field [0001] The invention relates to a method for fastening a filter insert in the body of a vibratory screening machine of an asphalt mixing plant, the use of this method, a vibrating screening machine of an asphalt mixing plant and Body, tie rods and screen inserts for such vibratory screening machines. Background technique [0002] Vibratory screens are mainly used in asphalt mixing plants for sorting sand or gravel and are located directly above hot mineral silos, so that in operation temperatures of several hundred degrees Celsius are often present in the screens. For this reason, almost exclusively, wire fabrics are used as sieve inserts, which are stretched in the longitudinal direction and mounted in the side regions on upwardly raised support flanges in order to maintain the necessary form stability. In screening machines with a working surface length of 5 m to 6 m, which are currently common, two screen inserts are arranged in succession per screen pane...
