Description

The invention relates to devices for. enrichment of materials and can be used in mining, agriculture, construction, chemical industry and other sectors of the national economy.

The aim of the invention is to improve the quality of enrichment due to the intensification of vibration breaking of dispersed materials.

In FIG. 1 schematically shows a general view of the installation; in FIG. 2 is a section AA in FIG. 1: in FIG. 3 - node in FIG. 1; in FIG. 4 - node II in FIG. 1.

.. The installation consists of a housing 1, in the left suit of which a pneumatic blower 2 is installed, to which an acceleration pipe 3 is connected. A vibrating hopper 4 and a loading nozzle 5, forming a loading device, are cut into the upper part of the accelerating pipe З. Above the upper perforated part of the end of the booster pipe 3, there is a g1 bT loule filling confuser 6 connected by an aspiration system. Perforation 7 was made in the upper part of the end of the booster pipe 7. A nozzle 8 was installed at the end of the booster pipe 3. A separation chamber was installed at the outlet of the booster pipe and made in the form of sequentially installed bioconical chambers 9 of rectangular cross section, above which set the confusers 10 connected by a pipe 11 to the cyclone 12 and the hopper 13 of the aspiration system. To ensure suction operation, a fan 14 is installed. A conveyor 15 is installed under the hopper 13 to discharge the cleaning products. In the lower part of the bioconical chambers 9 formed by transverse partitions, discharge nozzles 16 of enrichment products collection bins are installed, of which enriched and fractionated material is discharged by conveyors 17. Above the discharge nozzles 16 are mounted on the transverse partitions of the bioconical chambers 9, retractable vibrating plates 18 moving along the guiding 19. Opposite them on the transverse partitions installed pipes 20 with nozzles 21 directional action. The movement of the vibro-baffle plates 18 along the guides 19 is provided by the power cylinders 22. The transverse partitions are located

in the lower part of the separation chamber sequentially from the output end of the booster pipe. Vibro-baffle plates are installed towards the output end

booster pipe. Retractable plates 18 allow the height of their position to be adjusted on the respective transverse partitions.

Installation works as follows.

The enriched material from the loading pipe 5 under the influence of the vibrating hopper 4 enters the booster pipe 3, where under the action of high-speed air pressure

from the pneumatic blower 2 it moves along the booster pipe and through the perforation 7 and the confuser 6 is subjected to primary dedusting. The nozzle 8 at the end of the booster pipe 3 ensures the creation of optimal parameters of the jet of enriched materials, which, under the influence of dynamic and gravitational forces, are fractionated and collide with plates 18 made in the form of honeycombs.

The expansion of the boundaries of fractionation is achieved by the classification of dispersed materials with a particle size of less than 0.14 mm, which occurs sequentially in bioconic chambers as a result of exposure

particles of dynamic and gravitational forces are enriched, with particles of a larger fraction falling into the bioconical chamber closest to the accelerating tube, particles of a smaller fraction into the second, etc.

To adjust the boundaries of the fractionation, the plates 18 can be moved up and down along the guides 19 with the help of the power cylinders 22. The pipes 20 with nozzles located opposite to the baffle plates

21 provide compressed air blowing of the plates 18, which provides a higher quality of enrichment of dispersed materials. In the upper part of the bioconical chambers 9, confusers 10 are installed, through which

dusty particles are discharged through a pipe 11 to a cyclone 12 and then through a hopper 13 to a conveyor 15. The operation of the dust removal system is provided by a fan 14. Fractionated and enriched as a result

collisions with vibro-baffle plates and blowing compressed air through the discharge pipes 16 enters the conveyors 17.
