Description

The image (tsiye belongs to the woodworking industry and can be used in the preparation of wood particles in the production of draenaceous particles.

The aim of the invention is to increase productivity and improve the quality of nlits by ensuring uniform distribution of particles over the surface of the sieves and cleaning the latter.

FIG. 1 shows a diagram of the line of preparation of wood particles; in fig. 2 - sorting unit, top view; in fig. 3 - the same, longitudinal1 1Y cut.

The line for preparation of wood particles includes sequentially installed and technically connected bunker 1 of raw wood particles with a pneumatic line 2 supply,:, bunker 4 dry wood particles with cyclocems 5. sorting unit 6 with rotor 7 and many Russian sieves 8 and section 9 dorazmol, intermediate bunkers 10 d. 1 particles of the facing layer and 1 1 - D. 1I particles of the middle layer, mixers 12 d, 1I particles of the facing layer and 13 - for particles of the middle layer, conveyor 14 for mix, 1m 12 and conveyor 15 for mixer 13, as well as the festival 16, with the node 6 sortings and provided with a hollow drive va, 17, the first covering va. 1 rotor 7, and adaptive, 1pp 1H equal to the distribution of wood particles, a vibrating conical bottom 19 with annular drips 20 in its periphery, radially fixed on the bottom 19, rigidly fixed on the bottom 19, and also rigidly fixed on the shaft 17 , Blades 22, each of which is divided into 11ara, 1le, 1newn with each other by stepped slots 23 into separate elements 24, consists of a vertical, 1noy 25 and an inclined 26 parts, the closed walls 21 of the bottom 19 being displaced in the lower steps grooves 28 blades 22 and rigidly fixed conical sieves 27 for large particles and 28 for small particles, each of which is placed with a gap 29 in the upper stages of the corresponding grooves 23 blades 22, vergika.1bth parts of the blades elements , and in ko, 1tsevy Kana. ix 20 bottoms of 19 pa mutually perpendicular radii are made of rows of windows 30 d, 1 i of removal of large particles, 31 d.h of removal of soft fractions and 32 for ud, 1uc11 / cc, with these windows 31 and 32 are connected pneumatic lines, respectively, with nromezhugochi 1 1 bunkers 10 and 11, and a window 30 with a section 9.

K | About G01 about, above the bonds, with the 1st Ci sorting: ui is a cutting branch pipe 33, on the rotor 7 under the discharge branch pipe 33 is installed scattered by a cop with 34, and under the bottom 19 vibrator, 35.

Lini works as follows. The manufactured wood particles are conveyed by the conveyor 2 into the bunker 1 of raw chips, and then into the dryer 3. Dry wood particles are moved, along the pneumatic line to the bunker 4 of dry wood particles, then to the sorting unit 6. Hitting the zagruzoch nozzle 33, the particles are scattered by a cone 34 and the roto-, Q rum 7 are scattered. / The worm particles, depending on their mass, are distributed on sieves with different cell sizes. The heavier the particles, the farther they go. The pulverized fraction flies at a small parabola and falls on the conical part of the bottom 19, large particles of the years are of the greatest size and fall on the sieve 27, smaller particles fall on the sieve 28. Since the bottom 19 is equipped with vibrators 35, the wood particles, advancing to the 27 and 28 screens (they also vibrate, since they are rigidly fixed on the vertical closed walls 21 of the bottom 19), are more carefully sorted. At the same time, the rotating blades 22 will mix the particles along the surface of the sieves 28 and 29, direct them to the corresponding ok5 (30, 31 or 32) and simultaneously clean the sieve sieves.

The coarse particles that are not passed through the cruciform cells of the sieve 27 enter the window 32, and then to the area 9 for their re-grinding and re-sorting. Wood particles,

0 passing through a sieve of 27 with large cells, fall into window 30. Particles that have not passed through a sieve of 28 with smaller cells fall through the same. Wood particles that have passed through the smaller cells of the sieve 28, as well as 5 dusty particles that did not fall on the sieve, jump down the conical part of the bottom 19 into the window 31.

From the window 30, large wood particles enter the intermediate hopper 1 1 and then into the mixer 13 for tarring and depositing the conveyor 15 into the forming middle layer. From the window 31, smaller wooden pieces enter the intermediate bunker 10, then to the mixer 12 for tarring and transport by the conveyor 14 to form the facing () (H1)) layer.
