SU141057A1 - Vibrating screen - Google Patents

Description

The known vibrating screens for enrichment of aggregates of concrete, made in the form of a spring-loaded body, a vibrator with drive directional and flat stepped sieves, do not provide intensive cleaning of the aggregate.

Vibrating screen, made according to the invention, is devoid of this disadvantage.

The essence of the invention lies in the fact that its sieves are made in the form of truncated elliptical drums, in the middle part of which there are rods that regulate the required thickness of the glittering layer, near which canopies are installed, directing rubble under these rods.

FIG. 1 shows a schematic view of the screen in plan; in fig. 2 is a longitudinal sectional view thereof and in FIG. 3-side view of the rumble.

The frame / is the supporting part of the screen. The motor 2 causes the eccentric shaft to rotate. Clamps 3 are used to clamp the coupling on the shafts of the eccentric and the electric motor. Durite hose 4 provides a soft connection between the electric motor and the eccentric shaft. Springs 5 act as shock absorbers. The spring supports consisting of a heel and kerchief 6 are supports of the oscillating part of the screen. The diaphragms 7 serve to fasten all oscillating parts of the roar, including the vibrator. Grids 8 provide removal of impurities. To exit the rubble, an unloading hatch 9 was used. The JO vibrator case protects the eccentric shaft // and the bearings from impurities. The eccentric shaft is designed to create a directional vibrating screen. The guiding peaks 12 are designed to guide the rubble under the rods 13, regulating the required thickness of the layer, and placed in the middle of the sieves, made in the form of truncated elliptical drums 14.

Crushed stone through the loading hatch / 5 enters the first truncated elliptical drum. Due to the directional vibration, it receives oscillatory and rotational movements around the rod 13. The guide peaks 12 direct the rubble under the rods 13 and thereby improve the rotational movement of the rubble, and the rods provide the necessary thickness of the rubble directly above the grid 8, contributing to the intensive emission of impurities through it. Due to the overflow of the first drum, the rubble passes into the second one, and this cycle is repeated in each drum until the rubble reaches the last one, from which it goes to the means of transport through the discharge port 9.

The described vibrating screen contributes to intensive cleaning of the aggregate, increasing the screening surface. The vibrating screen is useful for the industrialization of non-metallic materials.

Subject invention

Vibrating screen, in particular for enrichment of aggregates of concrete, for example, rubble, including a spring-loaded case l vibrator directional action with a drive, characterized in that, in order to intensify the enrichment process of the aggregate and increase the screening surface, its sieve is made in the form of truncated elliptical drums, The middle part of which contains cores regulating the required thickness of the rubble, the oliz of which are mounted visors that guide the rubble under these rods.
