The invention relates to a device for liquid treatment of textile fibers, and in particular to equipment for processing wool fibres, in particular equipment for carbonization of wool fiber.

A device for washing wool fibres, containing the wash tub, the drum with the collector to drain solution [1]

The disadvantage of this device is the design complexity, the lack of reliability and poor quality processing of wool fiber.

A device for liquid treatment of a moving textile fabric containing a bath for a processing composition, provided with inlet and overflow fittings, divided in height into two sections: upper and lower. The lower section has a movable bottom, coupled with the means of communication to him of vibration and the top wall, made in the form of a chute for the passage of the blade, open side facing the upper section and having side walls along its length aligned openings communicating with the cavity of the upper section of the tank for a pulsating supply of processing composition on canvas [2]

The said device is intended for continuous processing of materials, such as cloth, but it is not capable of handling the short length fibers, such as wool fibers.

The closest analogue of the present invention is a device for impregnation of fibers containing a bath of processing liquid, the loading mechanism of fibrous material, means for feeding the processing liquid and the circulation system W is Arslanova fiber, because the processing of the fibers is in free fluid flow, when the intensity of the processing of the fiber is low.

In the processing of wool fiber in this type of installations is not even a complete immersion in the solution during the entire processing period. For complete impregnation in wool fiber vegetable matter is required to increase the processing time, causing reduced quality of the wool fibres. In addition, wool fiber with vegetable impurities loosely divided into individual fibrils, in the wet processing into a lump, the solution slowly penetrates lump and vegetable impurities even after prolonged treatment impregnated with weakly or not impregnated.

The aim of the invention is to intensify the process of wool fibers, for example, in the process of impregnation solution.

The technical result that can be obtained by carrying out the invention is to improve the performance of the device for liquid treatment of textile materials, as well as improving the quality of the processed material.

To do this in the bath for processing wool fiber is settled with moisture-permeable walls, one of which is made movable, connected with vibrooccasion and inclined in the direction of movement of the fibrous material.

Moving in a U-shaped pipe fibrous material is handled directional flow of the processing composition arising from the oscillatory motion of one of the walls of the bath. In addition, since the movable wall is inclined in the direction of the processing material, material moving inside the U-shaped pipe, the impact of the additional effort that will help him move. Thus, intensifying the process of fiber.

The drawing shows the proposed device, the overall look.

A device for liquid treatment of textile fibers contains a bath 1, in which the liquid processing of the fibers (baths depending on the conditions of the technology may be several), the loading mechanism of fibrous material (not shown), means for supplying the processing liquid into the tub, made in the form of a perforated collector 2, the circulation system of the processing liquid (not shown). Inside of the bath is placed a perforated pipe 3, U-shaped, designed for posting in the author and kinematically connected with vibrooccasion 5. This wall is inclined in the direction of movement of the fibrous material. The amount of tilt depends on the processed material and selected experimental way. Recommended value = 5aboutto the horizontal plane.

Bath also contains a threshold of 6 to create a level of solution in the bath. Tub is mounted on the frame 7. The lower part of the bath is equipped with a hopper 8 for draining sludge.

The device operates as follows.

Bath 1 is filled with a solution from reservoir 2 to the level defined by the threshold 6. Wool fiber loading mechanism, such as an automatic feeder, through the loading aperture is fed into the tub 1. Passing the collector 2, the fiber is irrigated with a solution and drops into the tub 1, moving through the pipeline 3. Because the upper part of the pipe 3 is located below the solution level 1, you can move wool fibre is completely immersed in the solution. When moving inside a pipeline 3 plot against the rolling of the bottom 4, the fiber due to the reciprocating motion of the solution caused by the oscillation of the movable plate 4 from the drive vibrator (force P), raspisivaetsya (cleaved) into individual fibrils. When this occurs leaching legkoatletki impurities from the wool fibres and lowering them into the residue in the funnel 8.

Because one of the walls of the bath (the movable bottom 4) is inclined in the direction of movement of the fibrous material, with its vibration wool fiber and the solution is given additional force F that contribute to moving the fiber along a bath.

After a bath or several baths (depending on conditions), where the processing is repeated, the fiber is fed to the subsequent processing. Washed from the fiber and accumulated in the tub impurities are periodically removed from the hopper 8.

The circulation system of the processing liquid is performed in a known manner and provides a continuous supply of solution in the first bath (if multiple baths), overflow in subsequent baths, drain into the collection from him in the discharge capacity and the subsequent pumping of the discharge capacity in the supply tank.

The proposed solution allows to considerably intensify the processing of wool fibers and to obtain new and useful technical result increased productivity device for liquid treatment of wool fibers, a reduction in the length of metal devices. The process liquid in the processing of wool fibres is reduced over time in 3-5 times, with the exceptions being the ptx2">

A DEVICE FOR LIQUID TREATMENT of TEXTILE FIBERS, containing a bath of processing liquid, the loading mechanism of fibrous material, means for supplying processing fluid and a system of fluid circulation, characterized in that it is provided with a means for posting the fiber below the level of the processing liquid, made in the form of a U-shaped pipe with a moisture-permeable walls, with one wall made movable, connected with the means of the message she vibration and inclined in the direction of movement of the fibrous material.
