The invention relates to devices for separating particulate matter and its gas flow.

The purpose of the invention is to increase the efficiency of material separation and reduce material consumption.

FIG. 1 shows the material separator, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one.

The material separator contains a cylindrical vortex chamber 1 with a swirler 2 connected by means of (a means of a longitudinal slot 3 with a material collector 4. The material collector 4 is made in the form of a longitudinal channel 5 having the shape of a V-shaped groove. At the bottom of the channel 5 accommodates a conveyor 6, for example, of a screw type. The rear part of the channel 5 is plugged with a wall 7, and in the front part in the swirl zone 2 there is an unloading nozzle 8 equipped with a shutter 9. The device also contains a tangential inlet nozzle 10 and an air vent nozzle 1

The cylindrical wall T2 of the vortex chamber 1 partially overlaps the cavity of the material collector 4, and the longitudinal slot 3 is made with an offset relative to the vertical axis of symmetry against the direction of the Motion of the material. Along the length of the swirler 2 above the longitudinal slit 3 is removable cover 13.

The material separator works as follows.

The air flow with dispersed material flows through the tangential inlet 10 to the swirl 2, where it acquires a rotational motion. Under the action of centrifugal forces, the material particles are pressed against the cylindrical wall 12 "and their green chamber 1 and move along it. The air flow in the vortex chamber 1, rotating along a converging spiral, leaves the branch pipe 11 through the air duct. Particles of materials Moving along the wall 12 of the vortex chamber 1, fall as they pass through the longitudinal slot 3 into channel 5 and unload conveyor 6 (via a pipe 8 and a shutter 9.

The displacement of the discharge pipe 8 into the swirler zone 2 allows the use of

Plug the material into the air duct 11 in case of possible external air leaks through the hatch.

Part of the cylindrical wall 12, located in the cavity of the material collection 4, serves as a baffle for the secondary gas flow.

When working with heavy material, in order to avoid its occurrence in the cooler 2, the removable cover 13 is retracted from the longitudinal slot 3. The longitudinal slot 3 with offset relative to the vertical axis of symmetry in the direction opposite to the material movement contributes to better separation of particles from the air flow. In addition, in the event of a fan stop, the material does not lie on the cylindrical wall 12. The maximum effect of material particle trapping occurs when the longitudinal edge of the slot 3 - the place of separation of particles from the cylindrical wall 12 - is at a distance h 0.7R from vertical axis of symmetry of the vortex chamber 1, where R is the radius of the vortex chamber 1. The loss of material in this case is 0.02%.
