Description

135. The support bracket 6 is rigidly mounted on frame 2, and the support bracket 5 by means of elastic joints 17. On B 8 and 9 with the possibility of their coverage, a joint venture is installed, made in the form of an endless elastic band 18 with openings in which grid bars located | across the ribbon. Under the upper branch | SP of the frame 2, a pallet 21 is mounted for receiving the undersize product. On pallet 21 fixed elastic

plates 24, on which the joint venture rests in the span between BB and 9. When the shaft rotates in the direction opposite to the rotation B 8, the latter makes spatial oscillations at connections x 17, deforming the joint venture. These deformations provide active cleaning of the gaps between the grate from particles stuck in them. The interplay of plates 24 with grate provides additional cleaning of the joint venture. 7 il.

I The invention relates to devices for the wet screening of fine-grained materials and pulps in metallurgical, ore dressing, coal preparation and other areas of the national economy.

; The purpose of the invention is to increase the efficiency of screening by reducing the degree of clogging of the holes of the sieve cloth by the grains of the screening material.

 Figure 1 shows the vibration; screen conveyor, side view; figure 2 is the same, top view; on fig.Z-sieve cloth, top view; Figure 4 shows the deformation of the screen, top view; in FIG. 3, view A in FIG. 4; figure 6 - the relative position of the balance, located on the shaft opposite the drum; Fig. 7 shows an elastic support plate, V1ad from the side.

The vibrating screen conveyor consists of a frame 1, a frame 2 installed on it, on which bunkers are mounted for feeding the source material 3 and receiving oversize product 4. On the frame 2 in the support brackets 5 and 6 are mounted in bearing assemblies 7 tension 8 and driving 9 drums. The drive drum 9 is driven by the motor 10 through the elastic sleeve 11. The tension drum 8 has an unbalance shaft 12 I installed on it with a turn of 120-135 debalances 13 and 14 located opposite (from different sides) relative to the tension drum 8. The imbalance shaft 12 is rotated by the motor 15 through the elastic coupling 16. The support bracket 6 is rigidly mounted on the frame 2, and the support bracket 5 by means of elastic ties 17. On the drums 8 and 9, a sieve cloth is installed in the form of besko echnoy elastic band 18 with openings 19 in which the grating bars 20 are mounted, arranged transverse

5 tapes. Under the upper branch of the belt 18 on the frame 2 there is mounted a pallet 21 for receiving the undersize product, consisting of separate sections 22. In the cavity of sections 22 brackets 23 are mounted with elastic plates 24 on which the belt 18 rests in the span between the drums 8 and 9.

Vibrating screen conveyor works as follows.

5 When the drums 8 and 9 are rotated, the screen sieve 18 with the grate 20 is fed: it moves in the direction from the tension 8 drum to the driven 9, the original pulp is fed to the sieve

0, the web 18 from the hopper 3 in the direction of flow and sieved during the movement through the upper branch of the web 18, gets into section 22 of the pallet 21 and is removed from the process divided into narrow classes of size. The oversize product is dropped into the hopper 4. When the unbalance shaft 12 is rotated in the direction opposite to the rotation of the drum 8 s, 311456249

No frame attached to each other on the frame, mounted on the frame of the Poen angle of 120-135 unbalances 13 and 14, with the help of the mounting brackets of the driving tension drum 8 makes simple and tension drums, sieve cloth,

oscillations on elastic st - made in the form established with the possibility of

the possibility of covering the drums of an endless elastic belt with grate bars located across the belt, a pallet for receiving the undersize product 10 placed under the upper branch of the sieve cloth with the possibility of supporting it, characterized in that, in order to increase the efficiency of screening by lowering (deforming) ) the blades ensure that the holes of the holes (the grating cloth are grained with small grains) between the grate bars 20 and the material that is not cleaned (the grating cloth) are actively cleaning the holes of the holes, it is equipped with an unbalance shaft,

H x 17, deformed screen sieve. Since the screen cloth 18 is made of an elastic material, for example a conveyor belt with a cord base, it oscillates close to shear in the plane of the web 18 (FIG. 4) and torsional in a plane perpendicular to the plane of the web 18 (FIG. 5 ). These colors are particles in them. The screen cloth 18 prevents elastic plates 24 from sagging, on which the belt 18 is supported in the span between the drums 8 and 9. In addition, the interaction of the plate 24 with the grate bars 20 on the frame by means of the elasticised web 18 provides additional cleaning due to: impact contact elastic plate 24 with rigid grate 20.
