Description

one

This invention relates to dust mites, which serve to evenly supply powders from a hopper.

Known is dusting, atelier, sod | rzhash, and a bunker with a perforated funnel installed inside it, connected through an intermediate shaft with an electric drive and with a rotating STEEL 1M: 1.

To ensure continuity of dust loading into the bunker in the proposed device, the bunker is provided with an annular protrusion on which a perforated funnel is installed, and two annular perforated disks mounted at a distance relative to each other above the perforated funnel.

FIG. 1 shows the described device, longitudinal rarese; in fig. 2-section

A-A of FIG. :one.

The evaporator consists of a hopper 1, inside of which a metering funnel 2 is installed with holes 3 having an external cutting KipoMKy 4. The funnel is connected via a rod 5 to an electric motor 6 and rests on an annular protrusion 7 and a seal 8. At the bottom of the hopper there are radially mounted plates 9, mounted on the bunker hull.

Two perforated plates are installed in the cylindrical part of the bunker: rotating with 10 and fixed.

Dust collector works as follows.

The funnel 2, in its rotation, with the edges of the 4 holes 3 cuts off a layer of dust located above it in the dust bin of the dust bin. Dust enters through the funnels of the funnel into the bunker and falls down.

Plates 9 exclude the rotation of the adjacent layer of the EYES together with the ic funnel during operation and the mold.

To ensure uniform pressure of the dust column on the rotating funnel in

the cylindrical part of the bunker has two perforated plates 10 and I, the performance of which is coordinated with the performance of the dust collector plates only in the presence of free space

above them. As a result, a constant level of dust and its constant pressure on the rotating funnel are maintained above the bunker, which ensures a uniform supply of dust.

To smoothly adjust the amount of dust supplied, the rotational speed of the engine is changed. For a discrete change in dust transfer, funnels with different total cross sections of holes are used.

Claims (2)

1. A dust collector containing a bunker with a perforated hole inside it, connect it through an intermediate shaft 1 with an electric drive and with a rotating rod, characterized in that, in order to ensure the continuity of dust loading, the IB bunker, the latter is equipped with a hook, which is equipped with a ring, which is equipped with a ring and a hook. on which perforated B0 | ro «ka is installed, and two annular perforated discs mounted at a distance relative to each other over the perforated voroika. 2. Dustpiper according to claim 1, characterized in that the upper disc is fixedly mounted on the wall of the hopper, and the lower one on the rotating rod.
