The invention relates to the separation of bulk materials by mechanical means and may find application in the separation of grain and its processed products.

Inertial separators are known, in which the working member is made in the form of a rotating disk with vertically mounted sieves j.

The disadvantage of such separators is that the sieves are prone to clogging with particles of the product to be separated. This reduces their effectiveness. Cleaning the sieves by reversing the rotor angular velocity greatly complicates the design of the separator. In addition, due to the high inertia of the floor, the particles of the product cause perforated wear of the perforated surfaces, which, due to the specificity of the design, cannot be repaired. The disadvantage is also the need to replace the perforated surfaces when switching from one product to another and feeding the product to sieves with a low initial velocity. The latter is due to the design of the power supply device, made in the form of a cylinder with windows, rotating with the rotor.

The closest in technical essence and the achieved result to the proposed is an inertial separator, including a distributor, a rotor with vertically mounted radial guides and separating blades, a loading nozzle, receivers of selected fractions and a rotor drive 2.

The disadvantage of this separator is low productivity, since the presence of a distributor and radial guides in it ensures a satisfactory distribution of the initial product to the height of the divided blades in cases where no more than 5-7 rods are contained in one blade, and when creating inertial separators large unit productivity the number of rods in one blade can reach 10-15 or more pieces. In this case, the distribution-. The known cone of the known separator does not ensure a satisfactory distribution of the product across all calibration channels, which leads to

reduce efficiency and productivity.

The purpose of the invention is to increase the productivity of the inertial separator by uniformly distributing the material. ,

This goal is achieved by distributing the device in the form of horizontal disc rings located one above the other, and at the same time the inner diameters of the rings decrease from the upper ring to the lower ring.

To adjust the distribution device to work with products that have different physicomechanical properties, each disc ring is equipped with an adjustment device, made in the form of a diaphragm, and interchangeable sleeves.

Figure 1 shows the inertial separator, a longitudinal section; figure 2 - distribution device, a longitudinal section; Fig. 3 shows the arrangement of the diaphragm blades and their attachment to the disk rings.

The inertial separator consists of a loading nozzle 1, a distributor 2, radial guides 3 of the rotor consisting of a shaft 4, a disk 5 and separating blades 6 made in the form of rods installed to form calibrating channels, receivers of fractions 7 and 8 with exhaust nozzles 9 and 10 and a drive with an electric motor 11, pulleys 12 and 13.

Distribution device

consists of a set of disk rings 14,

installed one above the other parallel to the plane of the disk 5 of the rotor separator. Disc rings secured. on the disk 5 through the sleeves 15 with the help of studs 16. The internal diameters of the disk rings are reduced from the top ring to the bottom one. An iris-type diaphragm is mounted on each disk ring, including petals 17 with grooves 18 and screws 19,

with the help of which the petals are fixed on the disk rings.

The separator works as follows.

The initial product enters the separator through the loading nozzle 1. Due to the fact that the diameters of the openings of the disc rings decrease from the upper ring to the lower ring, the product is divided into several streams, while the lower stream goes directly to the separator disc and the upper adaptations. Owing to the rotation of the disk rings, the product under the action of centrifugal forces moves to their periphery, acquires the necessary speed, and then enters the radial guides of the 3 separating blades in several jet streams. When moving along the radial flow guides, the product pulls the direction of motion and spreads up and down under the combined action of the centrifugal and Coriolis inertial forces, the force of gravity of the incident air flow. As a result, the product posts on the separating blades with an elementary layer. When the particles of the product move along the separating blades 6, they are separated according to their size through the calibrating channels formed by the adjacent rods, as well as the lower rods of each blade and the disk 5. These particles are directed to the receiver 7 and removed from the separator through the outlet nozzles 9. Particles, the size of which exceeds the maximum height of the calibrating channels, are removed from the separator through the nozzles 10. Setting up the switchgear to work with the product with the desired physical and mechanical properties vodits rozultvte to vary the distance between the discs 15 by replacing the sleeves and diameters of holes in the disc the rings moving along the petals I7 aperture slots Applying the proposed inertia separator allows significantly improve performance.
