Description

The invention relates to a device for cleaning down materials and can be used in the manufacture and restoration of down products.

A device for separating weed impurities and dust from an air-fibrous stream containing an arcuate pneumatic channel with ascending and descending parts, a grate, located on the lower surface of the ascending part, and on its descending part perforation is made, connected to an additional pneumatic channel, over which the exhaust is mounted means soropriemnogo camera grate [1].

The disadvantage of this device is that when used for cleaning fluff and feather, grate can be clogged with fluff and small feathers, as well as the fact that the flow of the processed material is not mixed during passage of the grate and perforated part of the air duct, which does not allow cleaning the volume of processed material.

The closest technical solution to the proposed invention is a device for cleaning fibrous material, mainly lint, containing a chamber, the middle part of which is made cylindrical, and the lower and upper conical, having a tangentially installed inlet pipe for supplying fibrous material in the upper part and an outlet pipe in the lower part a pipe for removing impurities, a pipe for removing purified fibrous material located along the axis of the chamber, and a reflector made in the form of a cone facing rshinoy to the pipe for discharging the purified fibrous material and installed coaxially with it [2].

The disadvantages of this device are the design complexity and large dimensions, the inconvenience of operation in conditions of use in consumer services during the restoration of down products.

The objective of the proposed technical solution is to reduce the dimensions of the device, reduce the cost of its manufacture by simplifying the design and improving the quality of cleaning down material from debris and dust.

The problem is solved using the proposed device for cleaning feather material, containing a tangentially installed pipe for supplying a feather mixture, a cleaning chamber, a pipe for removing the purified material, and the cleaning chamber consists of two chambers - external and internal, coaxially located one inside the other, each of them with the possibility of tangential air supply together with the processed material. Each of the chambers may contain obstacles installed on the inner part of the outer wall in the form of plates placed perpendicular to the tangent to the side surface of the chambers, or in the form of curved profiles installed so that rarefaction zones are created behind them along the rotation of the processed material. The base or side surface of the outer chamber is perforated with the possibility of pumping air through them. The inner chamber has a tangential nozzle mounted in such a way that the incoming air flow from the outer chamber creates a rotational movement in the inner chamber, the inlet of which is located inside the outer chamber. The pipe for the removal of purified material, the inlet of which is located in the center of rotation of the air flow, is designed so that the rotation of the broken pen and large debris occurs mainly in the space between the inlet of the pipe and the base of the inner chamber through which this pipe passes and allows you to position the device so that the axis of rotation of the processed material can pass both vertically and horizontally.

Distinctive features of the proposed technical solution are:

- the cleaning chamber consists of two chambers coaxially located one inside the other, which improves the quality of cleaning the material while reducing the dimensions of the device and allows it to be used in a limited space at consumer service centers;

- each of the chambers is made with the possibility of tangential air supply together with the material being processed, which allows for the rotational movement of the flow inside each of the chambers, as a result of which better cleaning of the processed material is ensured due to its separation into fractions during rotation;

- each of the chambers may contain obstacles installed on the inner part of the outer wall in the form of plates placed perpendicular to the tangent to the side surface of the chambers, or in the form of curved profiles installed so that rarefaction zones are created behind them to create additional vortices the processed material, which allows to increase the efficiency of the process of separating garbage from the processed material and its fluffing;

- the base or side surface of the outer chamber is perforated, which allows air to be pumped out through them, and therefore, to separate dust and small debris from the processed material and thereby improve the quality of cleaning of the processed material;

- a pipe for removal of purified material, the inlet of which is located in the center of rotation of the air flow, is designed so that the rotation of the broken pen and large debris occurs mainly in the space between the inlet of the pipe and the base of the inner chamber through which this pipe passes, which allows you to separate lungs with sailing fractions, cleaned of dust and small debris in the outer chamber, which are located closer to the center of rotation and are carried out with an air stream, and also position s device so that the axis of rotation of the processed material may extend both vertically and horizontally.

The combination of the above characteristics of the device allows you to get the following technical result: to simplify the design, improve the quality of cleaning down-feather material by removing dust and small debris by pumping air through the perforated wall and, while reducing the dimensions of the device, introduce an additional cleaning stage by placing a second cleaning chamber in it.

The proposed technical solution is presented in figure 1 and figure 2.

A device for cleaning down material includes an outer chamber 1, a tangentially located inlet pipe 2, a perforated wall 3 (the base of the chamber is perforated in the figures), an inner chamber 4, a tangentially located pipe 5 of the inner chamber, a pipe 6 for removing purified material, a pipe 7 for pumping air through the perforated wall 3, obstacles 8 (not shown in figure 1).

The device operates as follows.

The downy-feather material to be processed enters the external chamber 1 with a flow of air through a tangentially located inlet pipe 2, while in the chamber 1 a rotational movement of the processed material occurs. During rotation, the processed material under the action of centrifugal forces, due to different windage of different fractions (dust, small debris, fluff, feather, large debris), as well as hitting obstacles 8 and experiencing turbulence, is divided into components and fluffs, while the dust and small debris are removed through the perforated wall 3 with air pumped through the pipe 7, and large debris is located on the periphery of rotation and remains in the chamber 1. During rotation, the pre-cleaned and fluffy material through the tang A socially located inlet pipe 5 with a stream of air enters the inner chamber 4. In the inner chamber 4, a rotational movement of the processed material is created, during which it also experiences turbulence, passing obstacles 8, and is divided into fractions, while large debris not removed after cleaning the processed material in the chamber 1, rotating mainly in the space between the inlet of the pipe 6 and the base of the chamber 4 through which this pipe passes, remains in the chamber 4, and the cleaned material with a stream in air is discharged through a pipe 6.

The use in the proposed device of two coaxial chambers arranged so that the inlet of the tangentially located inlet pipe of the inner chamber is located inside the outer chamber, as well as chambers having different diameters, and the chambers can have different heights and are installed on the inner surface of the outer walls of these obstacle chambers, when reducing the dimensions of the device, it is possible to more effectively remove various fractions of garbage in each of the chambers, as well as increase the fluffability th material due to the fact that they are formed in the flow of the processed material to various sizes of power. The perforated base or side surface of the outer chamber allows dust and small debris to be removed at the same time as large debris and a broken pen are removed.

The possibility of arranging the proposed device in such a way that the axis of rotation can pass both horizontally and vertically, allows you to expand the range of equipment in which the proposed technical solution is used, using various design options, designed, for example, for operation in confined spaces, or having advanced functionality and usability.
