Abstract
The invention belongs to pulping and paper-making and artificial board production field, for a kind of timber, the bamboo wood of being convenient to transport raw material of chipping that formed after compression provides explained hereafter method, relate to the methods such as timber strips off the skin, timber, bamboo wood are chipped, sorting, drying, storage, compression, piling, packing.To solve the difficult problems such as wood chip in bulk, bamboo chip unit weight is little, volume is large, conevying efficiency is low, handling are inconvenient.For paper grade pulp provides a kind of wood chip, bamboo chip fibrous raw material of super quality and competitive price, not only greatly can alleviate the extremely low situation of China's wood chip utilization rate, significantly can also reduce the cost of transportation that external wood chip is transported back home.
Description
Technical field:
The invention belongs to pulping and paper-making and artificial board production field, for a kind of timber, the bamboo wood of being convenient to transport raw material of chipping that formed after compression provides explained hereafter method, relate to the methods such as timber peeling, timber or bamboo wood are chipped, sorting, drying, storage, compression, piling, packing.
Background technology
At present, fibrous raw material needed for domestic enterprises in pulp and paper industry can be supplied by self-operation forest farm or except the purchase of factory periphery except small part, major part need through national distance transport or from North America, Southeast Asia, transnational, the transoceanic transport in ground such as Australia obtain.But because wood chip, bamboo chip natural deposited dry density are less, therefore wood chip, bamboo chip transport become again the process of a poor efficiency, high cost.How improving wood chip, the efficiency of bamboo chip transport, reduction raw material cost of transportation, is the difficult problem that enterprises in pulp and paper industry is anxious for solution.
Based on above reason, the invention solves wood chip in bulk, the difficult problem such as bamboo chip unit weight is little, conevying efficiency is low, memory space is large and wood chip, bamboo chip utilization rate be low, simultaneously again for China's papermaking and industry of artificial boards explore production and the management mode of woods (forestry) plate (wood-based plate) paper (papermaking) slurry (slurrying) integration, the wood comprehensive utilization rate of China is significantly improved, makes high-quality timber can simultaneously by papermaking and industry of artificial boards are shared.
The content of invention
A kind ofly compress wood chip, production method that bamboo chip becomes block.Production technology comprises the operations such as timber peeling, timber or bamboo wood are chipped, sorting, drying, storage, compression, piling, packing.Timber (three surplus thing, undersized log), bamboo wood, through chipping, make it become the high-density state being easy to pack with geometry from loose low unit weight state by the mode of mechanical compress.
As shown in Figure 1, specific embodiments is as follows in technological process of the present invention:
(1) get the raw materials ready: by three of timber surplus things---the residue that logging residue, producing material residue, timber are processed and the partly applicable log of papermaking and the bamboo wood of felling are transported to the charge make-up area of factory;
(2) chip: wood raw material is sent in drum-type flaying machine by belt conveyer, is removed by the epidermis of timber, then by belt conveyer, the timber of peeling is delivered to drum chipper, timber is whittled into the wood chip of size specification; They are delivered to drum chipper by belt conveyer by bamboo, bamboo are whittled into the bamboo chip of size specification;
(3) sorting: with chip screen or chip screen, the silt in wood chip or bamboo chip, excessive and too small wood chip, bamboo chip are sorted out, retain remaining specification wood chip;
(4) dry: qualified wood chip, bamboo chip to be delivered to cylindrical drier or mesh-belt drier by belt conveyer and carried out drying and process, makes the initial moisture content of wood chip, bamboo chip be down to 6%-28% by 40%-100%;
(5) compress: dried wood chip, bamboo chip are delivered to chip bin, the bamboo chip feed bin with function of getting the raw materials ready by belt conveyer, then full-automatic extruder is delivered to again by belt conveyer, then by extruder, wood chip, bamboo chip are carried out to compression process, and be compressed into the cuboid of regular shape;
(6) piling and packing: the wood chip block, the bamboo chip block that are compressed into cuboid are delivered to the stacking machine adopting artificial or mechanical means by travelling belt transporter, by stacking machine carry out wood chip block, bamboo chip fast pile up neat, then carry out packing by packing program and process.
Compared with un-compressed wood chip, bamboo chip, feature of the present invention is:
(1) wood chip, bamboo chip moisture after super-dry and compression is down to 6% ~ 28% by original 40% ~ 100%.
(2) wood chip, bamboo chip are after drying and compress, and unit weight is by 250 original ~ 300kg/m
3bring up to 650 ~ 1100kg/m
3, volume reduces to during natural packing about 1/3 ~ 1/4, significantly can reduce transport and memory space, improves conevying efficiency, reduce cost of transportation.
(3) compress wood chip, bamboo chip regular shape, easily pile up and pile up, also can improve the operating efficiency of short-haul operation.
(4) wood chip, the bamboo chip mechanism completely by enough is compressing, does not add any adhesive, does not increase any pollution to natural environment, and wooden unit can expand after meeting water at once and scatter, and cracks equipment without the need to increasing to be correlated with.
Accompanying drawing explanation
Fig. 1 is the production-line technique flow process of compression wood chip of the present invention, bamboo chip block, and Fig. 2 is wood chip and the comparison diagram compressing rear wood chip block before compression, and Fig. 3 is bamboo chip and the comparison diagram compressing rear bamboo chip block before compression.
