Description
Technical field
The present invention relates to timber stoving technical field, and in particular to a kind of veneer drying system.
Background technology
In wood-based planet on domestic market, it is small that multi-layered board possesses modification amount, and structural strength is high, and environmental protection grade is high
The advantages that, and produce multi-layer sheet and relatively low are required to raw material, raw material supply is sufficient, and production cost low price is cheap, therefore more
The occupation rate of market of laminate is quite big.
Currently, domestic wood processing enterprise is when producing multi-layer sheet, in order to save cost, to the timber under being dug from log
Sheet material generally uses the processing method of natural-dehydration, i.e.,：Sheet material is dried in the sun, evaporates moisture by piece using sunlight
Material moisture content drops to 18% or so by original 40% or so, to the water content requirement of sheet material when reaching compressed laminated wood.This side
Method environmental protection and energy saving, without using additional energy source with regard to the purpose of desiccated wood can be reached.But the natural drying method when producing in enormous quantities
Have the following disadvantages：
1st, production active receiving climate has a great influence, and climatic condition change can have a strong impact on production task.
2nd, labor strength is high, and worker need to carry out moving upset to timber during drying, to ensure that moisture content is consistent.
3rd, production efficiency is low, and timber dries the time at 30 days or so under normal circumstances.
4th, production site requires sufficiently large, could be dried in batches.
5th, the larger area of air humidity is not suitable for being produced using drying method.
Therefore, in order to meet the requirement of industrialized mass production, it is necessary to the production method of this backwardness is eliminated, using one kind
Neither limited by climatic condition, production site, and can enough improves production efficiency, mitigates the advanced production equipment of labor strength
To complete the drying work to plank sheet material.
Investigation is found：In all wood processing enterprise factories, there is the heating center that heat supply is carried out to full factory.Heat energy is processed
Leftover pieces in timber process and waste material as fuel, are passed through combustion heating air, hot air temperature about 750 by center
Degree, hot-air are pipelined to heat transmission equipment and heat conduction oil by radiation and convection type, heat-conducting oil heating is arrived again
Be supplied to after 250 degree or so at plank press for it is compressing when use.Hot air temperature after heat exchange remains at 300 degree
More than, this partial heat energy can be used as the thermal source of steam generator.Most of factories are because heat energy is excessive, to 300 degree
Hot-air does not have more use demands, dirty so as to, into air, cause waste and a certain degree of heat by air flue emission
Dye, it is contrary to the Overseas Development direction of energy-conserving and environment-protective.
