Description

The invention relates to the wool industry, mainly to primary processing of wool, and can be used for continuous processing of wool by working compositions in the form of foaming detergents.

A device for washing wool is known as the five-rake barque of the MP-5Sh machine, which contains a body, cones forming a false bottom, an inlet conveyor, a soaking device, stationary rakes, a driving rake and an unloader. In addition, there are auxiliary mechanisms: a drain valve, a drain tank, a steam jet pump and a device for introducing steam (see Primary wool processing: a textbook for secondary special educational institutions / Gorbunova L.S., Rogachev N.V., Vasilyeva L. .G., Koldaeva V.M. - M .: Light and food industry, 1981, see p. 185).

A disadvantage of the known device is the use of a huge amount of water for washing wool.

The closest in technical essence to the present invention is a device for intensifying the washing of wool, which is part of the wool-washing unit, consisting of a conveyor belt for transporting wool to the washing barrels through a system of upper pressure rollers, a steam line with a pressure gauge, a thermometer and shut-off valves, providing steam from spray pipes into the contact zone of the upper pinch rollers and wool on the conveyor belt, as well as from the upper and lower removable rollers, which remove and feed from the conveyor belt to the washing barrels, steam-treated wool (see patent RU No. 2125128, D01B 3/04, O06B 3/00, publ. 01.20.1999).

The disadvantages of the known device include: spending a large amount of electricity when processing wool with steam, wool processing is carried out on the one hand, and this device is intended only for washing wool.

The objective of the invention is to provide a device with the ability to reduce water costs, easy to maintain, allowing a more efficient process of washing wool simultaneously from two sides.

The technical result of the invention is to reduce the cost of water for washing the wool, reducing the coats of wool, high reliability and the ability to install a device for washing wool in low-water environments in an automated line.

The technical result is achieved by the fact that the device for washing wool in low-water environments, containing a conveyor belt for transporting wool, according to the invention contains two working conveyors mounted one above the other, the belts of which are made of porous adsorbent material, for example lycra, drive and tension shafts of which are mounted on a bed with the possibility of rotation from the electric drive, on the idle branches of two working conveyors installed with the possibility of applying working compositions by rolling with the help of spreading devices located in the upper and lower parts of the device and consisting of bathtubs for working compositions in the form of foaming detergent and grooved shafts that are immersed in the bathtubs and installed with the possibility of rotation from the electric drive, between the drive shaft and the auxiliary shaft of the working conveyor technological shaft with the possibility of bending the belt of the working conveyor, and a squeezing shaft is installed under the drive shaft, in addition, the working bodies are installed in the upper and lower th part of the device and are made in the form of porous plates of elastic porous material, such as sponges, which are placed in the holder, and the working body located in the lower part of the device is mounted with the possibility of reciprocating motion perpendicular to the plane of the belts of the working conveyors, for example, by means of a crank the connecting rod mechanism, the conveyor belt for transporting wool is made in the form of a belt feed conveyor mounted above the tension shaft, and belt conveyors are installed under the drive shaft conveyor.

New design features of the claimed device are:

- installation of working conveyors on drive and tension shafts, which are mounted on a bed with the possibility of rotation from an electric drive, provides processing of fibrous wool materials;

- installation of a squeeze shaft under the drive shaft provides moisture reduction in the branches of the working conveyors and in the treated wool;

- installation of the process shaft between the drive shaft and the auxiliary shaft of the working conveyor allows you to create conditions for the separation of wool from the working conveyor on the scraper belt conveyor;

- the execution of the belts of the working conveyors of an absorbent material, such as lycra, allows you to process wool through the thickness of the tape of the working conveyor;

- installation in the upper and lower parts of the device of the working bodies, which are made in the form of porous plates of elastic porous material, for example sponges, which are placed in the holders, provides foaming and injection of foaming detergent into the wool processing zone through the thickness of the working conveyor;

- installation of plastering devices in the upper and lower parts of the device with the possibility of applying the working composition in the form of foaming detergent to the idle branches of the working conveyors, which consist of bathtubs for working compositions and corrugated shafts installed with the possibility of rotation from the electric drive and immersed in the bathtubs, allow applying foaming detergent on wool and working bodies;

- the execution of the conveyor belt for transporting wool in the form of a belt feed conveyor and installing it over the tension shaft of the device provides a smooth supply of wool to the working conveyor;

- installation under the drive shaft after the working conveyor belt scraper conveyor provides removal and supply of wool to another device.

In the course of experimental studies of the device, it was found that the foam bubbles of the working composition in the form of a foaming detergent when collapsing form high specific pressures on the surface of the contaminants, destroying all types of contamination of the fibrous materials of the wool. At the same time, water consumption is significantly reduced by 10 times, processing time is reduced, and the occupied production area is reduced.

The proposed device for washing wool in low-water environments allows the processing of wool to be carried out not in soap solutions, but by working compositions in the form of a foaming detergent, obtained in parallel with the process of transporting the treated wool between the working bodies.

The analysis of the prior art, including a search in patent documentation and scientific and technical literature, did not reveal sources with features similar to all the essential features of the inventive device for washing wool in low-water environments set forth in the claims.

The invention is illustrated by drawings, where in FIG. 1 shows a kinematic diagram of a device for washing wool in low-water environments, FIG. 2 shows a working member in the form of a porous plate made of an elastic porous material, for example a sponge, placed in a holder.

A device for washing wool in low-water environments (see Fig. 1, 2) contains spreading devices, which are located in the upper and lower parts of the device and consist of bathtubs 1, 2 for working compositions in the form of foaming detergent and corrugated shafts 3, 4, installed with the possibility of rotation from an electric drive (not shown), which are immersed in bathtubs 1, 2 for applying the working compositions in the form of foaming detergent to the idle branches of two working conveyors 5, 6. Two working conveyors 5, 6 are installed one above the other. The tapes of the two working conveyors 5, 6 are made of an absorbent material such as lycra. Working conveyors 5, 6 are mounted on a bed (not shown) on drive shafts 7, 8, tension shafts 9, 10 and auxiliary shafts 11, 12. Drive shafts 7, 8 and tension shafts 9, 10 are mounted for rotation from an electric drive (not shown). A process shaft 13 is installed between the drive shaft 7 and the auxiliary shaft 12, which bends the belt of the working conveyor 5. Under the drive shaft 8 there is a squeezing shaft 14. In the upper part of the device above the working conveyor 5 there is a working element 15 made in the form of a porous elastic plate porous material in the form of a sponge 16 placed in the holder 17 (see Fig. 2). The working body 18 is installed in the lower part of the device under the upper branch of the working conveyor 5 and is made in the form of a porous plate of elastic porous material in the form of a sponge 16 placed in the holder 17 (see Fig. 2).

The working body 18 is mounted with the possibility of reciprocating motion perpendicular to the plane of the belts of the working conveyors 5, 6 by means of a crank mechanism consisting of a crank 19 made in the form of a small eccentric 20 with a crankshaft 21. The fibrous materials of the processed wool 22 pass between two working conveyors 5, 6 and by working bodies 15, 18. Above the tension shaft 9, a belt feed conveyor 23 is installed for smoothly supplying fibrous wool materials 22 to the working conveyor 5, and under dnym shaft 7 after the working of the conveyor belt 5 is mounted conveyor 24 for removing the processed fiber materials with wool 22 working conveyor belt 5 and with the possibility of transport to another device installed in the automated line (in FIG. 1 not shown).

A device for washing wool in low-water environments works as follows (see Fig. 1, 2).

Working baths in the form of a foaming detergent are supplied to the baths 1, 2 of the spreading devices. The electric drive (not shown in FIG. 1) of the corrugated shafts 3, 4 and the electric drive (not shown in FIG. 1) of the drive shafts 7, 8 are turned on. Rotating, the corrugated shafts 3, 4 of the spreading devices apply by rolling the required amount of the working composition in the form of foaming detergent on the idle branches of the working conveyors 5, 6 and moisten the fibrous materials of the wool 22. The tapes of the working conveyors 5, 6 are saturated with a foaming detergent. Fibrous materials of wool 22, placed between the belts of the working conveyors 5, 6, are moved to the working area, where they, together with the belts of the working conveyors 5, 6, fall between the working bodies 15, 18 in the form of porous plates of elastic porous material. Fibrous materials of wool 22 are smoothly fed by a belt feed conveyor 23 to the working branch of the working conveyor 5, after which they are captured by the working branch of the working conveyor 6 mounted above the working conveyor 5 of the device. In contact with the working conveyors 5, 6 with the working composition applied to them in the form of a foaming detergent, the working bodies 15, 18 in the form of porous plates form foam, which is pumped into the working area, passing between the fibrous materials of the processed six 22. When the bubbles collapse on high specific pressures are created on the surface of the contaminants, destroying all types of contamination of the fibrous materials of the wool 22, and the residual detergents, along with the contaminants, are squeezed by the squeeze shaft 14. When working organs 15, 18, processed wool fibers 22 and working conveyors 5, 6, the effect of a sponge is achieved.

After leaving the processing zone, the processed fibrous materials of wool 22 are fed to a belt scraper conveyor 24, which, transporting fibrous materials of wool 22, removes them from the working conveyor 5 with the possibility of transportation to another device (not shown in Fig. 1) in an automated line.

To increase productivity, you can increase the width of the working passage or increase the number of working bodies.

The present invention, compared with the prototype of the device for the intensification of washing of wool (see patent RU No. 2125128, IPC D01B 3/04, D06B 3/00, publ. 01.20.1999) allows to achieve the following advantages:

- reduce the amount of water used for washing wool;

- to practically exclude the process of lapping wool;

- achieve ease of maintenance of the device;

- increase the reliability of the device;

- provide the ability to install in an automated line;

- reduce wool loss during washing.
