B, the bulk wood materials is carried out fragmentation decompose;
C, the sorting of pin roller screen form four types of super large wood chips, accepted chips, wood wool, wood powder impurity;
D, super large wood chip get into step b again;
E, accepted chips form medium density fibre board (MDF) after wood chip dry-cleaning-metal screening-cooker boiling-defibrator process-drying-applying glue-hot pressing-sanding-saw limit operation;
F, wood wool remove metal and powder is removed in sand grains-vibration sorting through selection by winnowing, form qualified wood shavings, then through roller drying-mechanical glue mixing-layering mat formation-hot pressing-sanding-saw limit operation after, the formation fiber particleboard;
G, wood powder impurity are transported to Bunker;
H, said sawdust wood shavings get into the selection by winnowing operation of step f step;
I, said discarded veneer are removed metal and sand grains after hammer crushing-drying-sorting, form particle, flake, force plane flower;
J, particle are after the vibration screening, and powder is transported to Bunker, and remaining is qualified wood shavings, gets into the roller drying operation of f step;
K, flake carry out the top layer orienting spreading after glue mixing, the force plane flower carries out sandwich layer machinery after glue mixing mats formation, so just form sandwich layer and be the force plane flower and up and down two surfaces be the slab of flake;
L, slab be transversal through precompressed-saw limit-form oriented wood chipboard after hot pressing-cutting edge.
The sanding powder that sanding operation among said step e, the f produces is delivered to feed bin.
The edge strip that saw limit operation among said step e, the f produces is delivered to feed bin after edge strip is broken again.
Said feed bin material gets into step f after metering-mechanical glue mixing the layering operation of mating formation.
The excessive wood shavings that vibration sorting operation is selected among the said step f are through carry out the shaking screen choosing after the broken operation again, and powder gets into Bunker, excessive wood shavings get into broken operation once more again, and qualified sawdust gets into the roller drying operation among the step f.
Said combustion bin connects boiler, and wood powder impurity is carried out burn processing.
The side plate that saw limit in the said step 1 is transversal, the cutting edge operation produces returns the hammer crushing operation of step I.
Good effect of the present invention: various waste woods are carried out classification processing; And being processed into the raw material of suitable medium density fibre board (MDF), fiber particleboard, oriented wood chipboard according to characteristics separately, the production technology according to corresponding regeneration composite plate is processed into medium density fibre board (MDF) or fiber particleboard or oriented wood chipboard again.And leftover pieces, sanding powder to producing in the various regeneration composite plate processes are recycled, thereby form comprehensive regeneration composite plate production method, rationalize, maximizedly make good use of various waste woods.
Description of drawings
Fig. 1 is the production method process chart that utilizes waste wood manufacturing regeneration composite plate.
The specific embodiment
Below in conjunction with accompanying drawing the production method of waste wood manufacturing regeneration composite plate of utilizing according to the invention is done further explain.
As shown in Figure 1, the production method of waste wood manufacturing regeneration composite plate of utilizing according to the invention comprises following processing step:
A, elect waste wood material branch as bulk wood materials, sawdust wood shavings, discarded veneer three types;
B, the bulk wood materials is carried out fragmentation decompose;
C, the sorting of pin roller screen form four types of super large wood chips, accepted chips, wood wool, wood powder impurity;
D, super large wood chip get into step b again;
E, accepted chips are after wood chip dry-cleaning-metal screening-cooker boiling-defibrator process-drying-applying glue-hot pressing-sanding-saw limit operation; Form medium density fibre board (MDF); Wherein, wood chip dry-cleaning is meant adopts the cleaning of special-purpose dry cleaner to wood chip, and its cleaning principle is the acting in conjunction of vibration, pulse pneumatic;
F, wood wool remove metal and powder is removed in sand grains-vibration sorting through selection by winnowing, form qualified wood shavings, then through roller drying-mechanical glue mixing-layering mat formation-hot pressing-sanding-saw limit operation after, the formation fiber particleboard;
G, wood powder impurity are transported to Bunker;
H, said sawdust wood shavings get into the selection by winnowing operation of step f step;
I, said discarded veneer are removed metal and sand grains after hammer crushing-drying-sorting, form particle, flake, force plane flower;
