Abstract
The invention belongs to the pulping papermaking and artificial board production field, provides a production process method for forming timber and bamboo chip raw materials convenient for transportation after compressing, and relates to methods of timber and bamboo chipping and drying treatment and compressing the chips to be blocks and the like. The production process method is used for resolving the problems that wood chips and bamboo chips in bulk are small in unit weight, large in size, low in transportation efficiency, inconvenient in loading and unloading and the like. The production process method provides wood chip and bamboo chip fiber raw materials with high quality and low price, thereby not only greatly relieving the situation that wood chip utilization ratio in China is extremely low but also greatly lowering transportation cost for transporting foreign wood chips to China.
Description
Technical field:
The invention belongs to pulping and paper-making field, for a kind of timber, the bamboo wood be convenient to transportation raw material of chipping that forms after compression provides explained hereafter method, relate to and timber or bamboo wood are chipped and be dried the process of carrying out the cuboid of compression molding shape rule after processing.
Background technology:
At present, the required fibrous raw material of domestic enterprises in pulp and paper industry except small part can by self-operation forest farm supply or the purchase of factory periphery, transnational, the transoceanic transportations in ground such as major part need to be through national distance transportation or from North America, Southeast Asia, Australia are obtained.But because wood chip, bamboo chip natural packing density are less, so wood chip, bamboo chip transportation become again a poor efficiency, expensive process.The efficiency, the reduction raw material cost of transportation that how to improve wood chip, bamboo chip transportation are the difficult problems 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, You Wei China papermaking simultaneously and industry of artificial boards are explored a woods (forestry) plate (wood-based plate) slurry (slurrying) integrated production and management mode, the timber comprehensive utilization ratio of China is significantly improved, high-quality timber can be shared by papermaking and industry of artificial boards simultaneously.
The content of invention:
The wood chip that a kind of slurrying is used, bamboo chip are compressed into the manufacturing technique method of piece.Production technology comprises that timber or bamboo wood chip and are dried processing, are compressed into the operations such as piece.Timber (as three surplus things, undersized log), bamboo wood through chipping, dry, the mode by mechanical compress makes it from loose low unit weight state, become the high-density state that is easy to packing with geometry.
As shown in Figure 1, specific embodiments is as follows in technological process of the present invention:
(1) get the raw materials ready: timber raw material are sent in drum-type flaying machine by belt conveyer, the epidermis of timber is removed, then by belt conveyer, the timber of peeling is delivered to drum chipper, timber is whittled into the wood chip of size specification; Bamboo wood is delivered to drum chipper by belt conveyer by them, bamboo wood is whittled into the bamboo chip of size specification;
(2) dry: qualified wood chip, bamboo chip to be delivered to cylindrical drier by belt conveyer or mesh-belt drier is dried processing, make wood chip, the initial moisture content of bamboo chip be down to 6%～28% by 40%～100%;
(3) compression: dried timber, bamboo chip are delivered to chip bin, the bamboo chip feed bin with the function of getting the raw materials ready by belt conveyer, then by screw rod transporter, deliver to again in the filling container of full-automatic extruder, by filler extrusion system, wood chip, bamboo chip are pushed, then enter in shaping dies, by moulding extrusion system, wood chip, bamboo chip are squeezed into the cuboid of shape rule, finally the briquetting displacement system by extruder shifts out briquetting.
Compare with not compressed wood chip, bamboo chip, feature of the present invention is:
(1) wood chip, the 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 compressing, and unit weight is by 250 original～300kg/m
3bring up to 650～1100kg/m
3, 1/3～1/4 left and right when volume reduces to natural packing, can significantly dwindle transportation and memory space, raising conevying efficiency, reduce cost of transportation.
(3) compression wood chip, bamboo chip regular shape, easily pile up and pile up, and also can improve the operating efficiency of short-haul operation.
(4) wood chip, bamboo chip are completely compressing by enough mechanisms, do not add any adhesive, and natural environment is not increased to any pollution, and wooden unit can expand and scatter at once after meeting water, without increasing the relevant equipment that cracks.
Accompanying drawing explanation
Fig. 1 is the compression device technological process of compression wood chip of the present invention, bamboo chip piece, and Fig. 2 is the comparison diagram that before compression, wood chip jade compresses rear wood chip piece, the comparison diagram of Fig. 3 bamboo chip piece for the front bamboo chip of compression and after compressing, the structure chart that Fig. 4 is full-automatic extruder.
The specific embodiment
The wood chip that a kind of slurrying is used, bamboo chip are compressed into the manufacturing technique method of piece.Production technology comprises that timber, bamboo wood chip and are dried processing, are compressed into the operations such as piece.Timber (as three surplus things, undersized log), bamboo wood through chipping, dry, the mode by mechanical compress makes it from loose low unit weight state, become the high-density state that is easy to packing with geometry.
