SU1212797A1 - Stage separator of grading wood particles in manufacturing wood particle boards - Google Patents

Description

The invention relates to separators for sorting wood particles and may find use in the production of chipboard.

The purpose of the invention is to improve the quality of sorting.

FIG. 1 shows a separator with zigzag partitions; in Fig., - 2 - view A in Fig. 1; in fig. 3 view B in FIG. one; in fig. 4 shows a section B-B in FIG. one.

The separator includes a housing 1 with a charging pipe 2, a exhaust hatch 3, a discharge pipe 4 and an inlet from the fan 5.

In case 1, zigzag partitions 6 are fixed, interconnected by hinges 7, and hinges 8 - with floating rods 9. Floating rods 9 by means of hinges 10 are fixed in slots 11 of housing 1. Through threaded rods 9 are missed washers 13 and adjusting nuts 14. Threaded rods 12 are fixed in housing 1.

The separator works as follows. "

rotation of the adjusting nuts 14 establish one or another angle between the individual zigzag partitions 6. The interposition of the partitions is also changed by re-installing and subsequently fixing the hinges 10 in the grooves 11. When the mixture of particles is fed into the nipple 2 of the separator and the air is forced between the zigzag partitions 6 by the fan 5 through, the entrance of small chips is picked up by the air flow and carried to the hatch 3, and the heavier particles fall out of the air mixture and are subsequently removed through the discharge gate. side-by-4.

Adjusting the quality of the separation of the particle material into fractions is achieved by changing the cross-sectional areas between the zigzags.

partitions by changing their angle of inclination, which leads in its own to the differentiation of the speed of air flow in the zone of each of the partitions along the entire height of the separator.

As a result of using a separator in the production of plate materials, the quality of separation of particles by fractions and thickness is improved, which

It makes it possible to improve the physicomechanical properties of the produced plates.

High-quality separation of chips and dust fractions from the sorted

mass allows to reduce the consumption of expensive binder for 1 m of manufactured products. The economic effect from the introduction of the line in the workshop with a capacity of 60 thousand meters of slabs per year is 998.4 thousand rubles.
