A device for washing fibrous materials, including leaching barcoo, a perforated cylinder with a piston connected to the mechanism for reciprocating motion, a pipeline with a can of compressed air and the outlet. In the perforated cylinder load fiber (wool), drop the piston, the system is immersed in bark with detergent solution. Then turn the engine mechanism of the reciprocating motion, the piston informs the fiber variables in the cylinder compressive force. When the vacuum in the barcoo is supplied compressed air, creating a shock wave, followed by a weak manifestation of the cavitation process, which contributes to the separation of impurities from the fibers and carry them in the washing medium. The frequency of cycles is set by the drive connecting rod-crank mechanism [1]

The disadvantages of this device are that in the presence of alkali, heat and mechanical stress (compression-rarefaction) are conditions for skolachivaniya weight wool. The process of cavitation generated by feeding a solution of compressed air provides efficient and complete separation pollution is italmost equipment.

Closest to the invention by the technical nature of a machine for cleaning hard, fibrous and elastic materials containing node feed of fibrous material, leaching barcoo, provided the means for the solution supply and discharge of cleaning fluid, a means for transportation, made in the form of a pair of perforated conveyors installed over them a number of electrodes in a straight line, parallel bearing branches conveyors, electrically connected to the pulse generator current (PCG), and the output node of the fiber material [2] the Conveyors form an PLoS-bone, which is the processed material. The cleaning solution is introduced into the bark through the fitting and passing in countercurrent to the material, is removed through outlet fitting. Under electrode mounted reflectors waves (pulses). The material is fed onto the conveyor and passes successively over the spark discharge gaps. Under the action of electro-shock, defined by the number of pulses in 1 m3the scrubbing medium (material) around the area are formed of ultra-high hydraulic pressure, causing the appearance of shock waves propagating with high velocities and mown, allowing mutual detachment from each other multicomponent bodies, as well as pulsed light, heat and ultraviolet radiation at a considerable power in the pulse.

Taken together, all these physical phenomena occurring in liquid medium placed in her material, have a significant and diverse physical and chemical effects, creating conditions for separating foreign matter (vegetable, mineral, fat and other substances) from the fibrous material. The quality and speed of treatment is determined mode of operation round depending on the capacitance of the capacitor (UF) and output voltage (kV).

The disadvantage of this technical solution are the following. The device is built on the principle of matching processes steeping, washing and propulsive in the same volume of washing solution that reduces the washing quality and productivity while increasing the consumption of detergents, water and energy. Transporting means made in the form of two conveyors and does not provide reliable fixation of the layer of fibers between the branches, which leads to migration of sheaves and complexes fibers in both directions, wilki. The electrodes are installed in a straight line, parallel bearing branches conveyors, creating a unidirectional action of electro-shock to the volume of the mixture material solution, which reduces the quality of washing and difficult removal of contaminants (impurities) of the material. The washing process takes place in conditions actions reflected wave (under electrodes installed reflectors), which reduces the effect of the separation of impurities from the material, as the power decreases electro-shock pulse, the performance of the equipment.

The design of the proposed device creates the conditions for a good washing of the material, improve the performance of equipment for economical consumption of detergents, water and energy.

The drawing shows a process diagram of the device of the washing fibrous material.

The device contains a node feed of fibrous material 1, the perforated conductive grounded conveyor 2, covering the three sections of the barge, the nozzle 3 mounted over the bearing branch conveyor first soak-off section 4, leaching section 5, is filled with wash solution, installed it guides the drums 6, between which is PE is neration 8 current pulses (PCG) electrodes 9, located in an arc concentric with the side surface of the drum. Over a third propulsive section 10 is installed nozzle 11 connected to the pipeline and pump (not shown). At the bottom of the third section has a drain valve and a pipe 12 connected to the nozzle 3. At the outlet of the third section is installed drive pulley 13 of the conveyor. The output node of the material made in the form of a removable-guide drum 14 and a pair of centrifuging drum 15.

The device operates as follows.

Material in the form of a fibrous mass, tape or cloth (fabric) using node feed 1 is directed to the bearing branch of the conveyor 2. When the material is washed torches fluid through nozzle 3 located above the first section 4 and the conveyor 2, where the material is subjected to intense lock with simultaneous leaching from him legkoatletki impurities that settle to the bottom section and are periodically removed through a drain valve. The conveyor 2 delivers the material in a medium wash section 5, in which he enters the cavity between the branch conveyor 2 and the arc of the drum 7, retracts into the cleaning solution and undergoes intensive treatment under the action of electro-shock created in the s DC from round 8. The electrodes are arranged in an arc concentric with the drum surface that enables the creation of volumetric electrohydraulic effect, manifested in the mechanical, physical and chemical effects on the cleaning solution and the material being processed. As a result of this comprehensive exposure to the impurities of plant, animal and mineral origin are separated from the fibrous material and pass through the cells of the perforation in the washing solution, which is followed in section 5 by periodically or continuously in the normal way through pipes and pumps. The spent solution will then be sent for cleaning or separator to extract the lanolin in the case of washing the wool. The intensity of the treatment of fibrous material in section 5 is determined, mainly, the operation mode of the generator 8 and to a lesser extent by the concentration of detergents and water hardness. For the purpose of washing is acceptable soft mode, characterized by the transformation of soft acoustic components of the sound radiation, the growth of infrared radiation, intense manifestation of cavitation and electro-shock becomes long and the projectile, causing the phenomenon of ionization of the solution, oscillatory digamadulla with foreign matter. Side a manifestation of the electrohydraulic effect is the suppression of microorganisms and the effect of bleaching fibrous material without damage to the natural properties of the fibers. The location of the electrodes 9 on the arc creates conditions for the formation of a volumetric field acting on the processed layer in three dimensions (lateral, longitudinal and perpendicular directions), intensive washing out impurities from the material. Explicit spark the working gap is created during arc between the electrodes 9 and grounded conveyor 2, electro-shock purposefully and effectively acts on the fluid and the material being processed. The intensity of this impact may be selected not only by changing the mode of operation of the generator 8, and the selection of material and configuration of the electrodes and wiring them relative to the grounded conveyor 2.

Thus, the design of the washing device has the ability to change modes of processing within wide limits depending on the type of fibrous material source and quality requirements for washing. High-performance and multi-faceted effects of electro-shock opens prospects is one of the conveyor 2 in propulsively section 10, in which it is washed by the torches of clean water using nozzles 11. Waste water through the drain valve and the pipe 12 is supplied to the injectors 3 for steeping. Drive pulley 13 of the conveyor 2 receives motion from the motor through an adjustable gear (not shown). The drum 14 removes the layer of fibrous material from the conveyor 2 and sends it to the clip of the drums 15, which removes the excess moisture.

The device opens the prospect of significantly higher quality of cleaning fibrous material and hardware performance, economy detergents, heat, water and energy.
