Wood drying device
Technical Field
The invention relates to the technical field of wood processing equipment, in particular to a wood drying device.
Background
The wood processing is that the timber is used as raw materials, mainly uses the processing of mechanical or chemical method, its product still keeps the basic characteristic of the timber, the timber in the course of processing, need dry the timber at first, this is the key to guarantee the quality of woodwork, it is the important means of rational utilization and saving timber, the quality of drying the timber has decided the processing quality of the subsequent process.
Traditional wood drying method, but the drying cycle is long in the mode of adopting open air to place more, and is inefficient, and adopt high temperature drying can effectively shorten drying cycle, high temperature drying can reduce ligneous hygroscopicity and internal stress simultaneously, thereby reach the purpose of increasing timber dimensional stability and improving timber corrosion resistance, nevertheless timber is by high temperature drying's in-process, along with moisture rapid evaporation in the timber, very easily arouse timber dehydration shrink deformation, ligneous local contraction arouses that timber internal stress is inhomogeneous, even lead to the condition of timber's fracture to take place occasionally, seriously influence timber's processing output and quality, cause ligneous waste.
If in the wood drying process, give timber external force, utilize external force to inject timber, make ligneous shrink deformation evenly distributed inside timber, can effectively prevent ligneous fracture, nevertheless because timber drying arouses that timber shrink is a continuation process, along with timber shrink, apply before timber drying for ligneous external force can become invalid gradually, consequently it is limited to prevent the fracture effect for the fixed external force of timber, and frequent adjustment external force can reduce ligneous drying efficiency and increase workman's intensity of labour, in addition, ligneous drying process need control the good temperature, and frequent change drying device's heating temperature, easily influence drying device's life, thereby reduce drying device's practicality.
