The invention relates to the industry of primary processing of bast cultures and can be used to isolate fibers from wet wastes from bast cultures, such as jute and kenaf. A known device for separating fibers from wet wastes of bast cultures, containing a ripper located in a raft channel, a series of perforated pipes transversely laid at the bottom of the raft channel and connected by a common pipe connected to a compressor, means for directing campfires including a float attached with t g to the inclined plank and to the lower part of the conveyor raising bonfires ij. The disadvantage of this installation is the possibility of the diverted fires in the raft channel, leading to re-contamination from scraping waste. Closest to the present invention is a plant for separating fibers from wet wastes of bast woods, containing separators mounted in a raft channel, alternating with conveyors for raising campfires and fibers, and means for directing campfires to an appropriate conveyor 2. However, when transporting large accumulations of fibrous waste, the separator, turning, abuts against the movable collecting Conveyor, lifts it and temporarily removes it from the stream. In this case, the capture of fires no longer occurs. The aim of the invention is to increase the efficiency of fiber cleaning. The goal is achieved by the fact that in a plant for isolating fibers from wet wastes of bast trees, containing separators mounted in a raft channel, alternating with conveyors for raising campfires and fibers, and means for directing campfires to an appropriate conveyor, the separator is pivotally mounted on a horizontal axis located across the channel on the edges of its walls, a valve for adjusting the channel cross section and located at the bottom of the canal In front of each successive separator, flow reflectors located perpendicular to the direction of its movement and having a cross-section in the form of an evenly circumferential right triangle, while the face of the reflector located along the hypotenuse is adjacent to the bottom of the channel, and the face located along the leg from the side of a smaller acute angle directed against flow direction. The means for directing fires is a tray consisting of two parts in the direction of flow of pivotally interconnected parts, with the front end of one part of the tray in the flow direction located in the channel at a level corresponding to the depth of movement of the fires, and the free end of the second part in the direction of flow movement of the tray is rigidly connected to the channel walls by means of a strip. The top of each of the reflectors is made rounded. Fig. 1 is a schematic of an installation for isolating fibers from wet wastes of bast trees; figure 2 is the same, top view; on fig.Z - section aa in figure 2; figure 5 is a valve, front view; in fig. section B-Bna figure 4; Fig. 6, means for directing fires, top view; figure 7 is a view In figure 6; in fig. 8 - section GGD 6; in fig. 9 is a section d-D in FIG. figure 10 - reflector flow, General view. The installation has an alloy channel 1, a valve 2 located across the channel on the edges of its walls, a separator 3 and means for directing fires 4, under which there are separators 5 pivotally connected to them and placed on the bottom of the channel 1 by each separator 5 reflectors flow 6. Behind the means for directing fires 4 there is a fire raising conveyor 7 and a sluice, 8 which directs the enriched waste water flow to the lowest possible processing. Fig. 3 shows a device for separating fiber from wet scrapping wastes, including a series of trays 9 consecutively located above each other, the movable end of which is rigidly connected by means of traces 10 to floats 11, and the latter in turn are located on both sides of the alloy channel. in special wells 12 connected to the main channel with the aid of grooves 13. In FIG. 4 and 5 depict a valve for adjusting the cross section of the channel, a shield 14 with a counterweight 15, placed across the alloy channel and rigidly connected to an axis 16, the ends of which are mounted on hinges 17, and a regulator 18 is attached to the hinge housing 17 the angle of rotation of the shield 14, containing a stop bar 19, having the ability to move in the grooves 20 and be fixed in a predetermined position. FIG. 6-9 depicts a means for directing a fire, which is a tray 9 (Fig. 3), consisting of two in the direction of replenishing the flow of a moving 21 and a fixed 22 trapezoidal-shaped parts, connected by a hinge 23 and a strap 24, ends which are located in the grooves 25 on the edges of the alloy channel, while the end of the movable free part of the tray is located in the channel and is maintained at a level corresponding to the depth of fire movement by floats 11, and the end of the fixed free part is rigidly connected to the walls of the canal and a strap 26. A separator 28 is mounted to the strap 24 by means of hinged hangers 27, which is a free-moving axle 29, on one side of which is the grate 30, having a circular cross section, and on the opposite side - a counterweight 31. Flow reflector (Fig. 10) placed across the alloy channel at its bottom and has a cross-section in the form of an unequal circumferential rectangular triangle, with the reflector face 32 located along the hypotenuse and adjacent to the channel bottom, and face 33 along the leg from the smaller acute angle and directed ive flow direction of movement. The top of the reflector is rounded. The installation works as follows. Waste quivering bast kenaf through the alloy channel 1 is fed to the plant for the separation of fibers from wet waste. Approach using water flow. to valve 2, wastewater deflects it to the stop 19 (Figs. 4 and 5), thereby constricting the water flow and increasing the flow rate at this point. The water along with the waste of scraping is pulled out at high speed from the shield 14 of the valve. At the same time, scraping waste, falling under the effect of a swirling water stream, is turned over, shaken and partially freed from the fires that float. Further, the scraping material under the action of the separator 3 is immersed in the lower part of the stream, and the remaining c on the surface of the fire freely passes between the grate bars of the separator 3 and enters the tray 9, the movable part 21 of which is under a small constant layer of water corresponding to the depth of movement of the main mass of fires, what is achieved by installation

two floats of 1C connected with this part 21 of the tray of 1 Dashuyu scale for tracking the water level and located in the separating wells 12 (fig. 3) along the edges of the alloy channel,

The grooves 13 connecting the wells 12 with the main channel have a smaller depth in comparison with them, which prevents the ingress of waste into them and contributes to the constant presence of floats in the water.

Waste trepan, passage under the trays 9, fall under the action of the flow reflectors 6, whose operation leads to an additional increase of fires. At the same time, a growing campfire falls on the movable parts 21 of the chutes 9, and the scraping waste shipped on

the bottom of the alloy channel separators 5, by the branch channel 34 is received for further processing.

A bonfire thus separated with an insignificant part of the water flow shakes the bonfire 7, on the conveyor of raising, the beginning of which is under the fixed part 22 of the last tray A, and then into the cart 35,

The use of the proposed plant for separating fibers from wet bast waste, cultures allows organizing reliable operation of subsequent technological machines, increasing their productivity, reducing fuel and electricity consumption, and ultimately improving the quality of short fiber. BUT
