(5k) SEPARATOR FOR BULK MATERIALS

one

The invention relates to separators for wood particles of chips, chips, sawdust, etc. and can be used in the woodworking industry in the manufacture of wood-based panels.

Separating devices are known that use the principle of mechanical throwing, according to which heavier particles thrown at a certain speed fly farther than light ones. On this principle works. a separator consisting of a hopper with a loading device for a tape accelerator, a separating chute, in which a variable inclination grid is installed, and a telescopic suction port l3.

The disadvantage of this separator is that a part of the fed particles to the accelerator rises, starts to hover over the material flow, not gaining the necessary speed, which is especially true for small particles and

dust, as a result of this, the separation process is disturbed, the productivity decreases and the dustiness of the environment sharply increases.

 Also known separator for bulk materials, mainly wood chips, including a housing, loading and unloading nozzles, a sieve mounted on hinges, a vertical eccentric shaft and

10 drive 23.

The disadvantages of this separator are low quality and low separation performance.

The purpose of the invention is to improve the quality of separation and increase the productivity of separation.

The goal is achieved by the fact that on a vertical eccentric

20, the impeller is installed in the form of a squirrel wheel, and the upper end part of the impeller is equipped with a driving pulley. FIG. 1 shows the proposed separator, a general view (in section); in fig. 2 - the same plan view. The separator includes a housing 1, loading 2 and unloading 3 nozzles, a sieve mounted on hinges 5, a vertical eccentric shaft 6 and a drive 7, the impeller 8 in the form of a squirrel wheel is installed on the vertical eccentric shaft 6, and the upper end part of the impeller 8 is equipped with a driving pulley 9 which is connected to the drive 7 by a V-belt transmission 10. The separator works as follows. The drive 7 is turned on to rotate the impeller 8. Through the loading nozzle 2, the wood particles are fed into the inside of the rotating impeller, from where the particles are thrown at different distances depending on the mass and windage under the action of gravitational and centrifugal forces. Wood particles with a greater mass, i.e. the larger inertia forces fly farther to the walls of the housing V and are directed to the nozzle 3 for the discharge of large particles, and wood particles with a smaller mass fall closer, fall on the sieve 4 and are removed only through the nozzle 3 for small particles. The proposed separator for bulk materials, mainly wood chips, ensures the quality of the separation of wood particles into fractions and improves the separation capacity. Claims Separator for bulk materials, mainly wood chips, including body, loading and unloading nozzles, hinged screen, vertical eccentric shaft and drive, characterized in that, in order to improve the quality of separation and increase separation performance, on a vertical eccentric shaft an impeller is installed in the form of a squirrel wheel, and the upper end part of the impeller is equipped with a driving pulley.
