Description

Production line of accelerated physicochemical processing of fiber-containing material containing bast.

The present utility model relates to the textile industry, and more specifically to the removal of impurities from material containing bast material.

A device for the chemical treatment of bast-fiber material (1). It has a chemical treatment device, which contains several sets, including a serially installed feeding device, a container for treating the flaming solution with a mechanism for conducting the tape stream through the processing solution, and shafts for extracting the solution from the processed tape stream.

A disadvantage of the known device is the low cleaning quality of the material containing the bast, isolation from other processes, as well as the complexity of the design of the pulling mechanism of the processed material. All this complicates the technological process of physicochemical processing and does not allow producing high-quality intermediate product.

The purpose of this utility model is to obtain a single technological process and improve the quality of the resulting final product, which will expand the scope of its use.

To this end, a flow line for accelerated physicochemical processing of a fibrous material containing bast, including a physicochemical processing device, comprising at least one set including a feeding device, a processing solution container with a mechanism for guiding the tape flow through the processing solution and shrinking rollers solution from the processed tape stream, equipped with interconnected sequentially installed in front of the device for physicochemical devices: disassembling the bale from the bast containing fibrous material, forming a layer with converting it into a tape, forming rolls from the specified tape and devices installed after the device for physicochemical processing: drying the processed tape stream, removing from it separated from the fiber as a result processing of weed impurities.

This goal is also achieved by the fact that in the specified production line between the bale disassembling devices and for the formation of the layer, the following are successively installed: a batch device for cleaning weed from fiber impurities with its simultaneous separation and a device for storing the pulp and supplying it with a layer forming device.

This goal is also achieved by the fact that in the production line, the device for separating with simultaneous cleaning of the fiber has a rotating drum with radial trenals located on the outside on the outside in the form of pegs, covering the outside of the drum with a grate with a grate and a periodically opening window valve for outputting the processed fiber with the system control the specified valve.

This goal is also achieved by the fact that in the production line, the device supplying the first container for the processing solution is equipped with a unit wetting the tape-stream, and each group of shafts for extracting the solution is equipped with a unit for washing the tape stream, and the mechanism for posting the tape stream is made in the form of at the inlet and outlet of the tank with a processing solution of conveyors and a pair of shafts between them to compress the tape stream.

Next, we explain the utility model using the drawings, which depict:

FIG. 1 is an aggregation diagram of production line devices for accelerated physicochemical processing of fiber material containing bast.

FIG. 2 - a device for physicochemical processing of a bast containing fibrous material.

FIG. 3 - device for cleaning fiber with simultaneous separation

The flow line in FIG. 1 consists of the following sequentially installed and kinematically connected elements: a device (1) for disassembling bales of fibrous material containing a bast, a device (2) for periodic cleaning of fiber impurities with its simultaneous separation, a device (3) for storing pulp and nutrition devices for forming a layer, device (4) for forming a layer, device (5) for converting a layer into a tape, device (6) for forming a roll from said tape, device (7) for physicochemical processing and FIG. 2, a feed device (8), a tape-wetting unit (9), a container (10) for the treatment solution, a mechanism (11) for transferring the tape-stream through the treatment solution, a conveyor (12), a pair of shafts (13) for compression belt-conveyor, conveyor (14), shafts (15) for squeezing the solution out of the processed tape-stream, washing unit-sprinkler (16) for washing the tape-stream, device (17) for drying the processed tape-stream, device (18) removal from it separated from the fiber as a result of processing weed impurities.

In FIG. 3, a batch device (2) for cleaning fiber from weedy impurities with its simultaneous separation has

a rotating drum (19) with radial bumps (20) arranged on the outside as pegs and a shell surrounding the drum from the outside (21) with a grate (22), a periodically opening valve (23) and a window (24) for outputting the treated fiber with the image not shown in the figure by the control system of said valve (23).

The production line works as follows. Bales with bast-containing fibrous material are fed into a bale disassembling device (1), where they are disassembled in layers and the pulp enters the batch device (2). In it, with the help of mounted on a rotating drum (19) ruffled (20) in the form of pegs, the fibrous mass is separated into small pieces. At the same time, due to centrifugal forces, self-gravity, and air suction, knocked-out intrinsic non-fibrous non-fiber impurities and parenchymal fibers are constantly removed from the device (2) through the grate (22). After several cycles of exposure to the fibrous material, the valve (23) opens and the cleaned fiber is removed through an open window (24), entering the device for storing the pulp (3). Then, in the device (4), the purified pulp is formed in the form of a layer and converted into a tape in the device (5). The ribbons in turn are folded together and form in the device (6)

roll. Thus, non-fibrous substances not associated with the fiber are removed, and a package suitable for further processing is formed. This causes minimal damage to the fiber.

Before the device for physicochemical processing (7), the roll is unwound and, using the rollers of the feeding device (8) and the conveyor (12), the pulp is immersed in the form of a ribbon stream in a container (10) with a processing solution. Before immersion, passing through pairs of rollers of the feeding devices (8), the fibrous mass of the tape stream with the help of a wetting unit (9) is pre-soaked to facilitate immersion in a container (10) with a processing solution. Near the bottom of the tank (10), the tape stream is subjected to compression by a pair of rollers (13) to pre-implant impurities that are separated from the fiber and can be removed together with the aqueous solution, and is directed upward through the conveyor (14) to the shafts (15) of the 11th solution extrusion from the processed tape stream, where the tape stream is flushed at the same time using the sprinkler device (16). The number of pairs of shafts (13) and / or (15) can reach four. Such physicochemical treatment of the ribbon stream can be carried out up to three times in order to ensure efficient removal of the fiber separated from it as a result of processing of non-fibrous substances-impurities that can be removed together with water.

(/ G

The processing time of the pulp in the working tanks from start to finish is 15-20 minutes depending on the quality (condition) of the feedstock. The magnitude of the removal of non-fibrous substances, after 3 single treatments, wringings and repeated rushing, is 15-17%.

Next, the tape stream is dried in the device (17). After drying with the help of a device (18) called a flaking unit, the surface crust is destroyed, and then the fibrous ribbon stream is processed on the second device (2), where the non-fibrous substances separated from the fiber are finally removed.

After that, the tape-stream is ready for further processing, as it has a high degree of purification from impurities that interfere with the production of high-quality yarn.
