The invention relates to woodworking and its industry, in particular to the production of chipboard.

The purpose of the invention is to improve the quality of the plates due to the uniform application of an antiseptic.

FIG. 1 shows the scheme of the proposed line; in fig. 2 - antiseptic injection mechanism, cross section; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - sorting unit, longitudinal section.

The line contains successively installed and kinematically interconnected receiving bins 1 for chips, chip machines 2, sorting 3 with outlets 4, antiseptic unit 5, dryer 6, raw chips 7 bins, sluice gates 8 with blades 9, main conveyor 10 with the forming machines 11, the sub-press 12, the hot press 13, the format-by-cutting machine 14, the grinding machine 15 and the drive 16.

Site 5 antiseptic chips placed under the hopper 7 raw chips. The sluice gates 8 are equipped with antiseptic redistribution devices 17 on the chips, which are made in the form of diametrically located between the blades 9 of each sluice gate 8 and kinematically connected plate rotors 18. The lamellar rotors 18 are mounted on coaxially mounted blades 9 sluice gate 8 pivot walls 19, and the blades 9 of the sluice gate 8 are S-shaped.

In addition, the line contains receiving bunkers 20-26, respectively, for lumpy waste of a wood-workshop, small-scale meter, sawdust, tarpaulin-veneer and lumpy waste of DOC, shavings of the table shop and DOTS, dry-shank bunkers 27, a common hopper 28 for chips from lumped waste of a wood-cutting workshop and imported chips, bunker 29 for chips from lumpy waste POC, chipper 30, common chip 31 for chips, hopper 32 of grinding dust. The bunkers 27 dry chips installed mixers 33.

Lamellar rotors 18 are mounted on shafts 34 mounted on central axles of buildings 35 of antiseptic units 5. The direction of rotation of the plate-shaped rotors 18 is opposite to the rotation of the blades 9 of the sluice gate 8. The blades 9 are mounted on the shafts 36.

Screws 38 and nozzles 39 for supplying an antiseptic are installed in the pipes 37 connecting the hoppers 7 of raw chips with the housings 35 of the antiseptic units 5.

A seal 40 is installed in the antiseptic unit 5.

Sorting 3 is made in the form of a housing 41 with a double-layered sieve 42. The upper rus 43 of which has a pallet 44, an air duct 45 with discharge 46 and an exhaust fan 47 and a regulating gate 48, while an inertial drum is installed between the sieve 42 and air duct 45 49. Injection and suction branches of the duct 45 attached to the body 41 of sorting 3 with elastic sleeves 50. In addition, sorting 3 contains additional grinding equipment 51, grill 52, inlet 53 and vibrating runner drive 54. Before sorting 3 is installed node 55 collecting chips.

For grinding machines 15 set table 56.

Lini works as follows.

Raw materials (tonkomer), coming from the forest workshop and having increased efficiency, are processed for chips using a chip machine 2. The lump waste, which comes from the forest workshop, is crushed using the chipping machine 30 to chips, which, together with imported chips are then processed for chips on centrifugal chip machines 2. The veneer is processed for chips using a centrifugal chip machine 2. The resulting raw chips and sawdust coming from the woodworking shop are sent to the bunker 31 and then dried in the dryer 6. At the same time, waste materials with low humidity, namely lumpy waste of DOTs, are crushed with chipper 30 for chips, which are then processed for chips using centrifugal shavings 2 and together with chips having low humidity coming from the DOTs and the table shop, sent to the chip collection unit 55, i.e., the chip collection unit 55 contains all the chips for which all the woodworking wastes are recycled, and their humidity in the node 55 is the same and equal to the moisture content of the DOTs, DOTs and the wood workshop . It should be noted that the resulting chips from soft waste

and torn veneer (i.e., on a drier waste stream) is micro-circulating and is used to form the outer layers of chipboard and provides high quality surface to the boards.

The whole chips are gradually fed to sorting 3, where they are distributed on vibrating two-layered screens 42 and 43. Small fine chips for the outer layers are sifted through the openings of the sieves and out of sorting 3 through the left nozzle 4, larger particles fall on the inertial drum 49 and due to inertia, heavier wood particles go through the right nozzle 4 to the expanding equipment 51, medium conditioned particles fall into the air stream created by the fans 46 and 47, and are carried to the process flow for One layer, the passage at the same time node 5 antiseptic.

Using the gate 48, the sorting mode is regulated, and the grate 52 ensures that large wood particles completely enter the right branch pipe 4. As an antiseptic, ammonium fluorofluoride is introduced through nozzles 39.

The design of the antiseptic unit 5 ensures thorough mixing of the chips with the antiseptic, since the chips produced by the screw 38 and moistened with antiseptic from the nozzles 39 are captured by the S-shaped locks 9 of the lock gate 8 and are moved not only by them, but also by the lamellar rotors 18, which direction is opposite to the rotation of the blades 9. Before the introduction of the resin and additives, the antiseptic chips must be dried up, for which they are sent to the dryer 6. The dried chips are collected in the left (fine fraction) and right (middle fraction) hoppers 27, of which the chips enter the mixers 33.

The prepared chips are sent to the left (fine fraction) and right (middle fraction) forming machines 11, with which carpets are layered in layers, then they are pressed into subpressing machine 12 and cut into a format in a format-edging machine 14. Next, carpets are loaded into hot press 13. Finished plates upt are grinded in a grinding machine 15 and placed on a table 56. Grinding dust is collected

into the hopper 32 and sent to the furnaces (i.e., they are not used for stoves, as it reduces the quality of the surface of the stoves). Then the cycle is repeated.
