Description

The designs of centrifugal and inertial dust collectors are known.

In the described design of the dust collector, in order to ensure a higher efficiency of gas or air purification from dust, in the case of a centrifugal or inertial dust collector there is a vibration filter made in the form of a rotating cylinder, the lateral surface of which is formed of tensioned strings with openings between them and vibrating when rotating or in the form of a coil spring with a vibrator. Through the vibrofilter, air or gas, partially dedusted in the dust collector body, is passed before it is discharged to the outside.

FIG. 1 shows a dust collector circuit; in fig. 2-diagram of the vibrofilter in the form of a spiral spring.

The vibration filter 2 is installed in the housing / dust collector. The latter is carried out as follows. The hubs 4 and 5 are fixedly mounted on the shaft 3, on which rings 8 and 9 are fastened through the spokes and 7. On these rings there are natnuty strings (wire) W with gaps between them 1-3 mm, forming a double mesh cylinder-vibrofilter 2. Lower the end of the cylinder is closed by a cone 11. The vibration filter 2 is set in rotational motion (the circumferential speed of the strings is 100-150 l / s) by the electric motor 12 through the sleeve 13. As the string of the vibration filter is rotated, it vibrates.

The vibration of the strings can also be caused by a vibrator installed in place of an electric motor. In this case, vibration filters are more expediently carried out in the form of a spiral spring 14.

Dust-laden gas (air) is introduced into the dust collector or tangentially through the nozzle 15, due to which rotational motion is communicated to the flow and, as in a cyclone, the dust is pressed against the wall of the body under the action of centrifugal force and lowered into the hopper 16

or axially through the pipe / 7. Then the dust by inertia moves linearly, slipping along the walls of the narrowing body /.

Partially dedusted air, changing its direction at an angle of 90 °, enters vibration filter 2 and through pipe 18 and pipe 19 by fan 20 is thrown out.

Vibration filter operates as follows.

Strings 10 vibrate at a rapid rotation and form around themselves a vibro-field, and dust cannot penetrate with a stream of gas through the gaps between the vibrating strings.

If the individual coarse dust particles, having a great speed and mass, overcome the resistance of the vibro-floor and penetrate into the gaps between the strings, they are thrown back by the centrifugal force to the wall of the dust collector body.

In the described dust collector, the separation of dust from gas (air) is carried out under the action of: centrifugal force of a tangentially directed flow or force of inertia of an axial flow; vibro-floor, formed by the strings of a fast-rotating vibrofilter or vibrating vibrofilter in the form of coil springs, pressing the dust to the wall of the dust trap body; centrifugal force of a rapidly rotating vibrofilter, made in the form of a cylinder, the lateral surface of which is formed by strings that throw dust to the wall of the dust trap body.

Subject invention

A dust collector, centrifugal or inertial, for separating dust from gas or air, including a vibration filter, characterized in that, in order to provide a higher degree of cleaning, the vibration filter is made in the form of a rotating cylinder, the lateral surface of which is formed by tensioned strings.
