NEW CONSTRUCTION CLEANER FIBER MATERIAL
Abstract: The recommended construction of fibrous material cleaners, mainly for cleaning wool from vegetable impurities, significantly increases the cleaning effect. The essence of the construction is that the fibrous material cleaner contains a conveyor system from the conveyor, corrugated feed rollers, a spear drum, a net surface beneath it, a serrated cylinder, a threading roller and a guiding fiber, a grate flange on elastic supports, a beating roller with an elastic element and Outer sleeve with a tooth on the surface, a working drum of rubber-skin material, a stationary knife, a bump roller with baffles on the surface, detachable brush shafts, a syringe and fiber tap.
Keywords: wool, cleaning, construction, cleaning effect.
In the known construction of the purification unit, mainly cotton from small and coarse litter contains sections for cleaning small and large litter alternate consecutively [1]. The cleaning section for small litter includes pin drums, a net surface beneath them and the large cleaning section contains serrated cylinders and grate bars below them. The main drawback of this construction of the fibrous material cleaner is the low cleaning effect and high fiber damage due to multiple mechanical influences of the working members with fibrous material.
In another known construction of the fibrous material cleaner [2], it contains vertical feed grate, director-plane, a pin drum, a three-lobed beater, firegrate, a horizontal grate, a smooth roller, a pin feeding roller, a table, a main grooving drum with conical pins and ribs, pinion, brush roller, comb drum, burr beater, corrugated drum, knives (grate bars), paddle roller, removable brush drum. The construction allows cleaning the fibrous material (wool) from dust, various impurities, especially from plant-derived impurities.
The drawback of this cleaner is the complexity of the construction, high-energy intensity and low effect of cleaning the fibers of the wool from plant impurities, especially the turnips, thorns etc.
In a known construction of a fibrous material processing apparatus [3], based on an under-life volatilization, which includes feeding seeds and nuggets to the area below the surface of the rotating saw cylinder, pressing the bundles of fibers to the teeth of the saw cylinder, moving the seed through the saw space and removing them by the conveyor. The fiber bundles of the non-gin volutes are compressed in the transverse direction and stretched along the saws, at the same time, fiber separation is carried out by applying the opposing moving forces of the discs to the seeds that changed the position in the vertical direction, after which the fibers from the
saws are removed by a detachable device, and the seeds separated from the fibers are removed by the conveyor.
The drawback of this construction is the low effect of cleaning the fibrous material in the processing of non-gin cotton leaf jet stream.
In the next well known construction of a fibrous material cleaner comprising a serrated cylinder and underneath the grate bars [4], which are mounted on elastic, supports.
A disadvantage of this construction is the low cleaning effect and a high percentage of fiber deposition along with rubbish.
The main disadvantage of the known construction of the fibrous material cleaner is the low cleaning effect and high damage to the fibers, as well as the inability to use this structure for cleaning wool from vegetable impurities.
The task in view is solved by improving the construction of the working parts of the fibrous material cleaner.
The essence of the construction is that the fibrous material cleaner contains a conveyor system from the conveyor, corrugated feed rollers, a spear drum, a net surface beneath it, a serrated cylinder, a threading roller and a guiding fiber, a grate flange on elastic supports, a beating roller with an elastic element and Outer sleeve with a tooth on the surface, a working drum of rubber-skin material, a stationary knife, a bump roller with baffles on the surface, detachable brush shafts, a syringe and fiber tap. The beating roller and the bump organ are made composite, from the drive shaft, on which the elastic bush is fitted; the working member is mounted on it. Due to the use of the feeding system from the conveyor, the corrugated feed rollers, the spear drum and the mesh surface under it allows sufficient loosening and uniform feeding of the wool to the cleaning zone. The stringing and guiding brush not only thread the fibers

of the wool into the space between the teeth of the saw cylinder, but also allows an even layer of wool fibers. The knockdown roller, due to the elastic bushing, makes additional torsional oscillations, which increases the effect of the cut-off of the vegetable impurities and separates them from the wool grabbed by the teeth of the saw cylinder. The grate also vibrating due to their elastic supports allows efficient isolation of weed impurities from the fibers of the wool. A working drum made of rubber-skin material; a stationary knife and a bump organ provide additional removal of wool fibers trapped by large vegetable impurities.
The recommended construction of fibrous material cleaners, mainly for cleaning wool from vegetable impurities, significantly increase the cleaning effect. The construction is explained by a drawing, where in Fig. 1 and the general scheme of the wiper of the fibrous material, in the Fig. B is the cross section A-A in Fig. 1 a.
The fibrous material cleaner consists of a casing 1, the feeding systems in it are fed in the form of a conveyor 2 feeding corrugated rollers 3,4, a tumbling drum 5, a mesh surface 6 beneath it, a serrated cylinder 7, which contacts a rotating threading and guide roller brush 8. On the left lateral side of the serrated cylinder 7 with defined gaps, trihedral grates 9 are mounted, which are fixed to the body 1 by means of trihedral elastic supports 10 (elastic rubber supports). A detachable bead roller 11 is installed under the grate 9 at a certain distance and with a certain clearance to the surface of the saw cylinder 7 and a removable brush roller 12 is installed on the right side of the saw tooth cylinder 7, the brushes that contact the teeth of the serrated cylinder 7. A working drum is mounted under the serrated cylinder 7 12, consisting of a set of disks made of rubber-leather material, which is pressed against a fixed blade 14 made of elastic steel with a certain pressure.

Figure 1. Fiber material cleaner
On the left side of the working drum 13 is installed a baffle roller 15 and a mesh surface 16, beneath it and a scoop-type auger 17. On the right side of the working drum 13, a detachable brush roller 18 and an air fiber spout 19 are in contact with it. The fibrous material cleaner operates as follows. Fibrous material (wool) with impurities enters through the conveyor 2 and grooved feed rolls 3, 4 to the spear drum 5. The toothing rolls the wool fibers through the mesh surface 6, the weeded ones fall into the breech through the opening of the mesh
surface 6. The loosened wool falls on the surface of the serrated cylinder 7. The brush roller 8 provides an even coat of wool and thread them into the space between the teeth of the serrated cylinder 7. The teeth of the serrated cylinder 7 graspis the fibers of the wool Carries through the grate 9, which vibrates due to the elastic cushions 10, while providing additional isolation of weed impurities from the wool. However, while the large vegetable impurities can remain in the wool and they continue to move with the serrated cylinder 7. These

large vegetable admixtures (burrs, thorns) are beaten off by a beating roller 11 and separated from the serrated cylinder caught by the teeth of the sawtooth roller. The wool fiberis grabbed by the teeth ofthe serrated cylinder is then removed from the teeth and diverted to the fiber outlet 19. The separated large vegetable impurities by the sales roller 11 have a sufficient percentage of the fibers of the wool. To separate these fibers from large vegetable contaminants, they are then fed to the surface of the working drum 13. The wool fibers are grasped against the surface of the working drum 13, by performing its surface from the composite material RSM (rubber-skin material). The fibers of the
wool adhered to the surface of the working drum 13 are dragged behind the fixed knife 14, and the large vegetable impurities are beaten off and separated from the wool fibers at the edge of the stationary knife 14 by the bobbin rolls 15 and retracted to the scoop by the auger 17. Part of the large vegetable impurities with a part of the wool fibers are dragged to the rolls 15, through the mesh surface 16 and re-enter the working zone. The wool fibers from the surface of the working drum 13 are removed with a brush roller 18 and retracted to the fiber outlet 19.The construction allows a significant increase in the purifying effect of wool fibers from large plant impurities.
