Description

I1

The invention relates to devices for separating fine fractions from a mixture of bulk materials or separating homogeneous granules during their formation from monodisperse product and can be used in the chemical, metallurgical, food and other industries.

The aim of the invention is to improve the quality and productivity of separation by increasing the path traveled by the material along the separating surface of the conical separator.

The separator works as follows.

The material is fed through the loading nozzle 4 to the conical separator 1 from the inside of the first turn of the spiral partition 5, which allows the material to pass along the entire partition. The vertical component of the screw oscillations of the separator displaces obliquely upwards along the surface of the conical separator I of the finely dispersed fraction of the material together with part of the captured large particles. The large particles that have separated are immediately released through the discharge pipe 8. A finely dispersed fraction with a part of the captured large particles, encountering an obstacle in the form of a diverging spiral partition 5, forms a vibro-boiling layer. The horizontal component of the screw oscillations of the separator simultaneously with the upward movement of the particles ensures their movement. In the vibro-boiling layer along the separating surface along the spiral partition 5. Large particles separated from the vibro-boiling layer are transported along the outer side of the spiral partition and dumped into an additional collection 7, the material cleared from them is poured into the discharge opening 6.

The presence of a spiral partition allows you to choose the length of the path covered by the material in the vibro-bunk layer, so that the material is separated in a single pass, and this ensures the operation of the separator in a continuous mode.
