Description

one

The invention is intended for the primary processing of bast fibers and can be used in the processing of flax trusts and complex. For long fibers.

Closest to the invention in its technical essence and the achieved result is an installation for treating bast cultures, containing a feed conveyor, a layer-forming mechanism with a feed conveyor, an actual device with loading and unloading units and a roller mill 1.

However, such an installation has poor performance.

The purpose of the invention is to increase productivity by combining reorientation operations and stem stem.

For this, the substantial device has a drum with radial sections for the raw material and (a stationary shell covering the drum sections along the rim and the front sides, the axis of rotation of the drum is inclined at an angle of 12-15 ° to the horizontal plane, the shell casing has an opening for loading the raw material , made “at the level of the feed conveyor of the layer-forming mechanism, and the end face (the casing is a hole for unloading raw materials located in the plane of the shaft shaft of the miniature device.

FIG. 1 shows schematically an installation for treating bast-cultures; in fig. 2-node zzgruzkn drying device; in fig. 3-tray dispenser of the actual device; in fig. 4-6 dosing tray at different stages of work; in fig. 7 - device for unloading the main device; in fig. 8 shows the arrangement of the pneumatic lines. The unit for processing bast cultivars (see Fig. 1) contains a feeding conveyor 1, a layer-forming mechanism 2 with a feeding center conveyor 3, a loading unit 4 for an insertion device 5, a drawing unit for an inserting device, flattening machine 6, a fiber separator for 7 sec.

rough conveyor and exhaust conveyor 8.

The desiccant device (see Fig. 2) consists of a drum divided into radial sections 9 for raw materials, and a fixed casing 10, which overlaps the sections of the drum along the rim and front sides, the axis of rotation 11 (see Fig. 8) of the drum being inclined at an angle 12-15 ° to the horizontal plane, the shell of the casing 10 has an opening 12

for loading the raw material, made at the level of the feeding conveyor 4 of the layer-forming mechanism 2, and the end surface of the casing 10 has an opening 13 for unloading the raw material placed in the plane of the shaft tip

flattening machines 6.

The drying device also has a duct 14 for iodachi heat carrier air and a pipeline for exhaust air suction (shown on the drawing).

Adjacent sections 9 of the drying device are divided by partitions 15 (Fig. 2), with the device outside being covered with a heat insulating layer 16.

The drying device loading unit 4 comprises a tray 17 and width guards 18, including one spring and one spring. The drying device also has an opening 20 for releasing the trusts and a directional stitching 21. The pneumatic conduit 22 serves as a pneumatic drain.

The plant for treating bast crops works as follows.

Formed: another layer-forming mechanism 2 layer trusts are fed into unit 4 of the loading of the drying device 5 in tray 4. Tray 17 is interrupted by such a number of trusts that need to load one section 9, after which the section is closed by limiter 18. Further damage to the ba; slave: on ensures the successive filling of .sections. During the period of one revolution of the drum (10 min), under the action of the coolant (air), it is dried to a moisture content of 12-14% and supplied to the unloading unit, which is also the feeding unit of the puller 6. At the approach of section 9 from the trust to the trust shield 21 of the trust under the action of the slip force, since the drying device has a slope of 12-15 ° to the horizontal plane, slides onto the guide shield 21 and is guided along it to the working bodies of the thickening mask 6.

Then the truss is carried out by fiber finishing machine 7. Next, the bleached, grooved, parallel, long fibers are removed from the outlet conveyor 8 and formed into rolls. A made drying drum with radial sections and a casing excludes a separate onotherapy for reorientation of the stems in the zone between the drying and small devices, since this operation is carried out simultaneously with the drying, which increases the productivity of the installation.
