Description

The invention relates to tex

tilting industry and allows to increase the efficiency of dedusting due to the fact that the device for dedusting fibrous material containing the chamber in which the perforated drum is located, the internal cavity of which is connected to the vacuum means, the inlet pipe communicating with the dedusting zone formed by the side surface of the perforated drum, side wall chamber and a vacuum valve; it contains an additional dedusting zone formed by the opposite side wall of the chamber, perforated drum and vacuum valve. 2 Il.

The invention relates to the textile industry and is intended for use in preparatory spinning.

The purpose of the invention is to increase the efficiency of dust removal.

FIG. 1 given the device, a general view; in fig. 2 - the same cross section.

The device contains a camera 1 with an inlet pipe 2 and an outlet port h. A perforated drum 4 is mounted in chamber 1. Under perforated drum 4, drum 5 is located on the same axis as it, which has flexible blades 6 that serve to remove dust-free fiber into outlet 3 and function as a vacuum valve that isolates the subsequent machine’s hopper from the zone

low pressure device. The perforated drum 4 divides the chamber 1 into two zones 7 and 8 of dedusting. One of the walls of each zone serves the perforated surface of the drum 4, on the other hand, the dedusting zone is bounded by the wall 9 of the chamber 1 _s and the other zone is limited by the wall 10 of the chamber 1. The side walls of the chamber 1 limit both the dedusting zone 7 and the zone 8. The internal cavity of the perforated drum 4 connected through the side channels 11 to the suction openings of the fan 12 connected to the pneumatic system. ^one

Fibrous material by air

current under the action of vacuum created by the fan 12, enters

in input patch 2 and split

on two streams _£ one of which, co 1542973

holding the fiber, with great speed is sent to zone 8 and approaches the drum 5. Another stream, which contains lightweight dust and fluff, which has a lower speed than the fiber, enters the dust-removal zone 7. Through the perforation of the drum 4, dust and down penetrate into its internal cavity and through the side channels 11 are sucked off by a fan.

Due to the fact that air is sucked through the entire surface of the perforated drum and the force of suction acts on the fiber, the latter is easily and intensively separated from the flow of the fiber-air mixture.

Claims (1)

Claim A device for dedusting fibrous material containing the measure includes a perforated drum, the internal cavity of which is in communication with the vacuum means, an inlet pipe communicating with a dedusting zone formed by the side surface of the perforated drum, the side wall of the chamber and a vacuum valve associated with the outlet pipe, characterized in that improve the quality of dedusting, the device has an additional dedusting zone formed by the opposite side wall of the chamber, the surface of the perforated drum and the vacuum valve, and communicating at the approach point of the flow of air-fiber mixture to the perforated drum by means of a curved channel with an inlet nozzle for separating lighter particles from the flow.
