Abstract

This invention relates to the separation of bulk materials in feed, milling, coarse, and other industries. The purpose of the invention is to increase the efficiency of material separation due to the additional selection and removal of the coarse elastic fraction. For this, between the distribution sieve (P) 2 and the separation P 3 located below it horizontally, there is a device for additional selection of the elastic coarse fraction in the form of several grooves (G) 4. The longitudinal axis Ж 4 are parallel to each other and the plane P 3 and with the longitudinal axis P 3, the angle is less than 90 °, the top of which is directed towards the loading part of P 3. The upper wall (C) 7 of each Ж 4 is located at an angle of 45 ° ≤ β * 9890 ° K to the MOUTHONE. CLEARANCE COOK by the surface of the p. 2 hp ff, 3 ill.

Description

The invention relates to the separation of bulk materials, a large fraction of which has greater elasticity than the fine (grain and products of its grinding) and can be used in animal feed, flour milling, large and other industries.

The aim of the invention is to increase the efficiency of material separation due to the additional selection and removal of the elastic coarse fraction.

FIG. 1 shows a separator, a vertical section; in fig. 2 is a section A-A in FIG. one; on a cig The 3-dependence of the recovery coefficient of a normal separator works as follows.

The original grain material enters the distribution sieve 2, under the action of vibrations and its own weight spreads over the whole or most of its surface, passes through the sieve 2 openings and falls off in a rarefied flow, accelerating under the action of gravitational forces. Having flown the distance from sieve 2 to separating sieve 3, the south part of the particles is sifted through its orifices, and a part hits its surface and reflects into the superlattice space in the direction of the sieve inclination. With

crushed wheat; the dependence was obtained experimentally for fractions (passage through a sieve with openings with a diameter of 1.0 mm, descent from a sieve with an opening of 0 0.5 mm):

mm

In this case, most of the reflected elastic velocity from the angle of installation of sycody particles, reaching the height of the installation for different sized fractions of the battery of the grooves 4, flies into the gap

between the bottom wall 8 of the gutter and its upper insole 7 and falls inside the gutter. The less resilient bore particles, moving over sieve 3 under the battery 20 chutes 4, after several collisions with the sieve, are sieved. Gathering particles into the gutters 4 are transported along them to the collection channel 6, and then they are combined with the gathering particles in the 25 outlet channels of the separator. Randomly trapped particles 4 in the gutters pass through them through the holes in the bottom of the gutters, again on the separation sieve 3, and, passing through it,
