Description

one

The invention relates to a technique for grading materials by size and can be used in the building materials industry, in mineral processing and in other areas of the national economy.

Known air separator containing made in the form of a double cone housing with located inside the double cone and the separating funnel and the inlet chamber with a tangential nozzle.

The aim of the invention is to increase the particle size separation efficiency.

This is achieved by having a separatory funnel mounted above the double cone. At the wide end of the separating funnel and on the double cone, clamps are mounted.

FIG. 1 and 2 shows the proposed device in section.

The separator consists of a housing 1, made in the form of a double cone, an inlet chamber 2 with a tangential nozzle 3, an internal double cone 4, a separating funnel 5, grippers 6 and 7.

The source material together with the air flow through the tangential nozzle 3 enters the inlet chamber 2, where the dust-air mixture receives a rotational motion. Larger particles as a result of centrifugal forces displace smaller particles closer to the axis of the separator. The fine particles are picked up by the air flow and carried to the chamber 8 of the topcoat product. Large particles are poured down into the chamber 9 of the coarse-grained product in the wall of the housing. Large particles that accidentally fall into the chamber of a high-grain material, under the action of their own weight, will roll down over the surface of the upper double cone and fall into the chamber of a coarse-grained material.

Finding the optimal separation parameters is carried out by moving the separating funnel 5, the cylindrical end of which extends outside the separator's cornis, relative to the double cone. Using the separating funnel as a manipulator, they lower it closely onto the double cone 4 so that the grips 6 of the separatory funnel 5 enter the grips 7 of the double cone 4. The displacement amount is fixed using ticks located on the outer part of the cylindrical separating funnel pipe 5. After moving the double cone at the desired height clamp the locking screws, the claws are disengaged. Then at the required height set the separating funnel 5.
