SU382441A1 - DEVICE FOR SEPARATION OF BULK MATERIALS - Google Patents

Description

one

A device for dividing bulk materials into fractions is known, comprising a housing with a loading chute, a dust extraction pipe and discharge ports, a rotating distribution body and rigid rings connected to the housing.

The purpose of the invention is to improve the efficiency of the device.

This is achieved by the fact that the distributor body is made in the form of a conical plate, around which separator rings are installed, equipped with knives, forming discharge channels, above which inclined protective covers are fixed, and an annular disk connected to the drive is mounted on supporting and centering rollers.

FIG. 1 schematically shows the proposed device, a general view; pa fi1. 2 is a picture of the movement of particles of material on the surface of a conical plate and an annular disk.

The device comprises a casing 1 with a loading chute 2, in which a distribution body, made in the form of a conical plate 5, is mounted on the support 3 and centering 4 rollers. The distribution body is connected kinematically through a gearbox 6 to the drive 7. The casing 1 has a dust extraction pipe 8 and has discharge ports 9 Around the conical plate 5, the devices are rigidly connected to the casing 1 by means of

brackets 10 separating rings //, fitted with curved knives 12, forming discharge channels 13, above which inclined protective covers 14 are fixed, preventing ingress of excreted fractions of the material into adjacent discharge channels.

Under the separating rings 11 on the supporting 15 and centering 16 rollers mounted kinematically connected to the actuator 17 is an annular disk 18, performing fractions of the movable bottom of the receiving and unloading channels formed by separating rings // and knives 12. Working surface

the annular disk 18 is covered with resipa and forms a mini-minima gap with the lower edges of the separating rings.

Under the discharge packs 9 are mounted oblique chutes 19, under which the belt conveyors 20 are located.

Subject to separation, the material is fed through a loading chute 2 onto the surface of a rotating conical plate 5, from which, under the action of centrifugal forces, is thrown along a complex ballistic trajectory. Different in bulk or mass particles of the bulk material due to their different kinetic energy describe different trajectories. Uniform in volume or mass

particles fall into the corresponding receiving

channels formed by separating rings and.

The number of separation rings is selected depending on the physical properties of the material to be divided and on the technological requirements for the fractional composition of the product. Due to the rotation of the annular disk / 5, the separated fractions are moved but the receiving channels to the discharge channels 13 and the blades 12 are diverted to the discharge ports 9, from where paired conveyors 20 are fed through the inclined chutes 19.

Subject and use of an ipte n E Device for dividing bulk materials into fractions containing a case with a loading chute, a steam outlet pipe and discharge ports, a rotating distribution body and rigidly connected separation rings with in order to increase the efficiency of work, the distribution body is made in the form of a conical plate, around which there are installed separating rings, equipped with knives, forming discharge channels, over which inclined protective covers are fixed, Under the separating rings on the support and centering rollers there is mounted an annular disk associated with the drive.
