The prior art sherstomoynoy aggregates of different structures containing autobytel unwashed wool, scutching machine, washing machine, consisting of several barges with rollers, autobytel scoured wool and drying machine (Primary processing of wool: a Textbook for middle. spec. educational. institutions/Gorbunova HP and others - M.: Light and food v the terrain, 1981, S. 165 - 168, 197 - 200).

A fundamental part of sherstomoynoy units and technological process carried out in them, the same for all units. The differences in design, especially in a washing machine, affects the quality of washing the wool. The composition of the washing machine includes three to six washing barges and the same amount of press rollers located after each barge. The number of used boats depends on the type of wool and extent of contamination. Most often used petibone sherstomoynoy units. Sixth barcoo set at the beginning of the washing machine as soaked or at the end - as additionally propulsively. The process of washing the wool in its early stages, involves as one of the components of the soaking operation, in which the wool fibers before obrabotkoi impurities.

A disadvantage of the known sherstomoynoy units is that the existing equipment does not allow to speed up the process of washing the wool by eliminating or reducing the time consuming process of soaking or reduction in time of the washing process, without compromising the quality of the processed raw materials and maintaining physical and mechanical properties of pure fiber.

The closest analogue, taken as a prototype of the claimed invention, a unit for processing of wool, containing autobytel unwashed wool, scutching machine, washing Barki, squeeze rollers, autobytel scoured wool, drying machine, and provided with a device for intensification of washing the wool, set the course of the process before the first washing barkai and comprising a conveyor belt for transporting wool in the washer barcoo, pipe-spray and shut-off valves (USSR author's certificate N 988906, class D 01 B 3/00, 1981).

Intensification of washing the wool in the known unit, mainly, will be done by improving the quality of washing the fibers by soaking in an aqueous medium under pressures greater than atmospheric. This is followed by transfer of the treated fibers in the first washing barcoo, as the supply of wool in the storage hopper is made periodically, portions for processing under pressure in the working chamber.

There is a method of liquid treatment of fibrous material, mainly wool, containing the operations of the purge material ferry, sealing and washing in detergent solutions (USSR author's certificate N 1671741, class D 01 B 3/00, 1991). Leaching is conducted according to normal process mode, but with a reduced residence time in solution at low concentrations of detergent and less water. This method of washing the wool significantly (30-50%) to speed up the washing process by the rapid melting of wool fat, contributing to the weakening of the intermolecular forces of adhesion between fiber and fat, easy removal of grease and dirt aqueous solutions of detergents. The known method provides for maintaining the quality of the fiber by reducing the time spent wool in the washing solution.

The present invention enables a method of liquid treatment of fibrous material.

The technical problem to be solved by the claimed invention is the acceleration of the process of washing Shehada of energy and water.

Sherstomoynoy unit consists (Fig. 1) of autoritatea unwashed wool 1, scutching machine 2, a device for intensification of washing wool 3, washing barges with rollers 4, autoritatea scoured wool 5, drying machine 6.

A device for intensification of washing wool 3 (Fig. 2) set the course of the process before washing barkai, consists of conveyor belt 7 for the transportation of wool, of the upper pinch rollers 8, the steam pipe 9 with 10 gauge, thermometer 11, a shut-off valve 12 and the pipe-spray-13, top 14 and bottom 15 removable cushions.

The combination of all the essential features that determine the composition of the proposed sherstomoynoy Assembly and being an integral part of it, allows you to use sherstomoynoy unit as the unit of continuous action and achieve the desired results in the solution of technological tasks of the invention.

Distinctive features of the proposed sherstomoynoy unit is the fact that the device for intensification of washing wool 3 is equipped with a system of the upper pinch rollers 8, the steam pipe 9 with 10 gauge and thermometer 11 and the upper 14 and lower 15 removable the priori valve 12 provides a supply of steam from a pipe-nozzle 13 in the zone of contact between the upper pinch rollers 8 and wool on the conveyor belt 7. The use of essential differences in the inventive sherstomoynoy the unit allows to perform a method of liquid treatment of fibrous materials (ed. the certificate in USSR N 1671741 class. D 01 B 3/00, 1991) and reach provided by the invention process result.

Sherstomoynoy unit (Fig. 1) works as follows.

Raw (unwashed wool or waste) autoritatea 1 comes in a scutching machine 2, then passes through a device for intensification of washing wool 3 and served for washing in the first and subsequent washing Barki with rollers 4. At the end of the washing process net wool through autobytel 5 serves for drying in a drying machine 6.

A device for intensification of washing wool 3 (Fig. 2) works as follows.

Unwashed wool (or waste) from which(s) after scutching removed Legrottaglie pollution, neuderzhimye coat is applied to the surface of conveyor belt 7 under the upper rollers 8 in the area of process steam coming from a pipe-nozzle 13 of the steam pipe 9 with a stop valve 12. Steamed wool is removed from the conveyor belt 7 removable bottom cushion 15 and served in moeciu the ferry coat and takes her also, in the washing barcoo. The 10 gauge and thermometer 11 serves to control the pressure and temperature of the steam in the steam pipe 9, and the shut-off valve 12 provides a flow of steam from the steam pipe 9 through a pipe nozzle 13 in the zone of contact between the upper pinch rollers 8 and wool on the conveyor belt 7. The upper rollers 8 create the necessary density of compaction of the fiber before blowing him up steam.

Experimental studies with the layout of the claimed sherstomoynoy unit in comparison with known showed the possibility of accelerating the process of washing the wool and receive with clean wool fiber that meets the quality standards requirements of existing standards. The residual nechestnyh components in industrial-net weight standards should be up to 1% (GOST 25590-83 Coat. The norm of the residual nechestnyh components and moisture conditioned-net weight"). The acceleration of the washing process is achieved by reducing the duration of soaking and washing the wool during processing of fiber ferry implemented in the device for intensification of washing the wool. The wool after processing the ferry coming in the washer bark has high wettability, due to this, in delineament costs by the number of detergents, water and reduce job of cleaning boats.

The table shows the comparative technical indicators when washing greasy wool and waste at the proposed and known (grade SP-1) sherstomoynoy units.

Sherstomoynoy the unit containing autobytel unwashed wool, scutching machine, washing Barki, squeeze rollers, autobytel scoured wool, drying machine and a device for intensification of washing the wool, set the course of the process before the first washing barkai and comprising a conveyor belt for transporting wool in the washer barcoo, pipe-spray and shut-off valves, characterized in that the device for intensification of washing the wool is equipped with a system of the upper pinch rollers, steam with pressure gauge and thermometer and the top and bottom removable cushions, and removing the feed from the conveyor belt washing barcoo steamed wool, when this shut-off valve ensures a supply of steam from a pipe-nozzle to the zone of contact between the upper pinch rollers and wool on the conveyor belt.
