A kind of energy-efficient veneer drying unit
Technical field
The invention belongs to timber drier technical field, particularly a kind of energy-efficient veneer drying unit.
Background technology
Wood single-plate, is again musculus cutaneus, wooden skin, and its thickness is generally between 0.4-10mm, and main application is for producing the artificial boards such as glued board, core-board, template, thick china; Veneer divides two kinds of rotary-cut and slicings, and veneer is dried or airing is the product that consumes a large amount of labours.
Traditional drying mode is that a sheet by a sheet airing of wood single-plate that rotary-cut or slicing are gone out is under sunshine, evaporate and make wood single-plate become dry by moisture, but the defect that this airing mode exists is to take a large amount of places, production efficiency is low, the easy turnup distortion of wood single-plate after airing, difficult quality guarantee, but also to be subject to the restriction of weather conditions.
Much the drying plant of veneer manufacturer is exactly that earth kiln formula is dried now, roasting with fire, also musculus cutaneus can be dried in this way, but water content is very inhomogeneous; Given this, now large-scale factory has just quoted advanced drying plant, and with conduction oil oven dry, such production line, not only flatness is good to dry the veneer, and water content is also more even, but up-front investment is large, and power consumption is large, and production cost is high.
Chinese invention patent (patent No.: 201120161205.X) discloses a kind of lignum veneer drying-machine, mainly utilize and in baking oven, be horizontally disposed with multiple roller groups, each roller group comprises a corresponding upper roller and the lower roller arranging, lower roller is the active roll tube being driven by power set, the above and below of multiple roller groups is respectively arranged with heat abstractor, roller group clamping wood single-plate moves ahead in process, the wood single-plate that rotary-cut goes out becomes smooth smooth and dry because of the clamping and the extruding that are subject to upper roller and lower roller, but this lignum veneer drying-machine is due to the design of multiple roller groups, exist oven dry veneer skin quantity little, area occupied is large, within the unit interval, dry veneer skin quantity few, production efficiency is relatively low, production cost is high.
