Abstract

A DEVICE FOR SEPARATION OF WEED IMPURITIES FROM FIBER, containing a cylindrical perforated chamber mounted obliquely to the horizontal plane with a material loading and unloading mechanism, nozzle ,. associated with the injection pneumatic system, and a collection of trash impurities, which is so that in order to increase the efficiency of the process, the chamber has a drive for it. rotation and contains pegs, fixed around the circumference on one third of its inner surface in the middle along the length of the part, and fixed transverse screen in its upper part, the area of which is half the cross-sectional area of the chamber, while the nozzle is mounted inside the chamber and the outlet is facing the screen, and the pegs are placed between the nozzle and the screen.

Description

fiKoinafS

of air.

The invention relates to equipment for the separation of trash from fiber and can be used in the woodworking and textile industries.

A device for separating weed impurities from a fiber is known, comprising a cylindrical, inclined to a horizontal, plane, perforated chamber with a material loading and unloading mechanism, a nozzle associated with an injection pneumatic system, and a collection of weed impurities C

A disadvantage of the known device is poor-quality separation of trash, for example, bonfires, flax fiber.

The purpose of the invention is to increase the efficiency of the process.

This goal is achieved by the fact that in the device for separating trash from fiber, containing a cylindrical perforated chamber installed inclined to the horizontal plane with a mechanism for loading and unloading the material, the nozzle connected to the injection pneumatic system and the trash device is the drive for its rotation and contains pegs, fastened circumferentially on one third of its inner surface in the middle length, and transversely mounted s. its upper part is a stationary mesh screen, the area of which is half the cross-sectional area of the chamber; the nozzle is mounted (torn inside the chamber and its outlet opening is facing the screen, and the pegs are placed between the nozzle and the screen.

FIG. 1 shows a diagram of the proposed device; in fig. 2 shows section A-A in FIG. one.

The device for separating trash from the fiber contains a cylindrical perforated chamber 1 mounted obliquely with the horizontal mechanism 2 loading and unloading material 3, srplo 4, connection with the pneumatic injection system 5, and the trash collection 6 trash its rotation contains pegs 8, fixed circumferentially on one third of its inner surface, and a fixed mesh screen 9 transversely installed in its upper part, the area of which is half the area of the transverse chamber section, the nozzle 4 is mounted inside the chamber and its outlet opening turned toward the screen 9 and pegs 8 are placed between the nozzle 4 hours screen 9; The inner core of the chamber is made of metallic threads 10.

The device works as follows.

A mixture of ground annuals

plants consisting of particles of fires and bundles of fibers, which are products of flax or hemp stalks, are continuously supplied by the vibrating feeder1 to the loading opening of the end of chamber 1 onto metal threads when passing through the tray, the vibro-feeder is self-sorting particles: the final separation of the material into fractions occurs in the chamber, which is driven by the drive 7. When the chamber is rotated, all free parts of the fires slide into the grooves of the

Do the filaments and fall on the smooth bottom of the camera, which is set at an angle to the horizon. .From fiber bundles as they roll and move along vibrating yarns 10 permanently

The bonded particles of bonfires fall out and fall to the bottom of the chamber, advancing the collection to b. In the central part, the caulk-metal spikes 8 pick up the fiber bundles and lift them into the zone of action of the air nozzle 4, to which compressed air is supplied through a fixed hollow shaft, under the action of which the pegs 8 are released from the fiber bundles. When the beams strike the screen grid 9, the crushing of the remaining particles takes place and additional particles are extracted from them. The material, separated by compressed air, moving along the grid, again drops down to

smooth metallic threads

This campfire falls to the bottom of the chamber, and the cleaned fiber bundles

The yarns are fed to the discharge mechanism 3, in the form of a conveyor.

Due to the rotation of the chamber 1 and the effect of compressed air, the sorting material is prevented from clogging the grooves between the threads, since the stuck parts fall out of them, i.e.

they are self-cleaning, which significantly improves the quality of product separation on the fraction. The capacity of the separator is adjusted by varying the rotational speed of the drum chamber.

The use of the device of the proposed construction makes it possible to isolate particles of fires and clean bunches from the crushed annual plants.

fibers. Bundles of fibers, peeled

bonfires are a good substitute for wood in papermaking in pulp and paper industry, and bonfire particles are the raw material for the production of tiled me

Heaters Bonfires of fires are used in construction as well as in furniture production. In terms of their physical and mechanical properties, these slabs are not inferior to wood chipboards made from expensive technological wood raw materials. Using sorted from shredded stalks of annual plants that were previously burned. For technological reasons, it significantly reduces the consumption of scarce wood.
