The invention relates to dust collection in ore mining enterprises and can be used in cleaning dust streams containing ferromagnetic particles, in particular, for selecting ferromagnetic particles from the aspiration emissions of the GOKov crushing plants.

The purpose of the invention is the cleaning of large volumes of dusty air from ferromagnetic particles, reducing the hydraulic resistance of the apparatus and simplifying the regeneration process.

FIG. 1 shows a dust collector, a general view; in fig. 2 - the same, top view; in fig. 3 - sedimentary plate, general view; in fig. 4 is a sectional view. A.-A in FIG. 3; in fig. 5 - scraper device, general view.

The dust collector consists of a rectangular body 1, a supply 2 and a discharge 3 gas ducts. In the lower part of housing 1, a dust collector 4 is attached, in which a scraper device 5 is placed. In housing 1, a pack of precipitation plates 7 is suspended on rods 6. In the inlet duct 2, in the lower part a cantilever apron 8 of flexible material, such as a conveyor belt ribbons supported by stops 9.

The scraper device 5 through the shaft 10 is driven into rotation by the drive 11. The precipitator plates 7 (Fig. 5) are made of a non-magnetic grid 12, in the cells of which there are flat ferrobarium magnets 13. The scraper device 5 (Figs. 6 and 7) is the systems of arc-shaped scrapers, which are cantilever-mounted on a common shaft, are positioned relative to each other at an angle of 180 ° and installed in the gaps between the settling plates. Each scraper consists of an arcuate rib 14, to the end of which is attached a strip 15 of soft material, for example, a conveyor belt. The strip 15 through the bar 16 is rigidly fastened with a bolt 17 to the rib 14. The latter is rigidly fixed on the sleeve 18, in the center of which the restrictive ring 19 is installed.

Dust collector works as follows.

When installing the arcuate scrapers 14 to a horizontal position, the dusty stream at a speed of 3-4 m / s through the inlet duct 2 is directed into the channels between the collecting plates 7. Particles with magnetic susceptibility are attracted to the collecting plates 7. The remaining dust The flow through the discharge duct 3 is directed to a standard dust collector. 0

When a layer of ferromagnetic particles accumulates, the M drive is turned on, and the scraper device 5 removes the accumulated material from the surface of the precipitation plates 7 into the dust collector 4. From the latter, the accumulated material is periodically sent to the technology of the plant, mine the process of wet enrichment. After making 3-4 revolutions of the drive, the scraper device takes up a horizontal position.

Installing the apron 8 in the inlet duct 2 helps reduce the flow of dusty air through the dust collector 4. Restrictive ring 19 installed

 on the sleeve 18, centers the lower part of the precipitation plate 7.
