Description
Technical field
The invention belongs to Wood Drying Technology fields, and in particular to a kind of Wood drying apparatus.
Background technology
The drying of wood is process procedure mostly important in woodwork production process, and it is total that energy consumption accounts for woodwork production
The 40%~70% of energy consumption.To timber carry out it is correct, rational be dried, be both ensure wooden quality key and
Rationally utilize and save the important means of timber.
Vacuum drying of wood is fast with its rate of drying, and dry mass is good, is applicable in the advantages that material kind is mostly small with floor space, quilt
It is considered the drying of wood new process with development prospect.But there is also some defects for vacuum drying, are such as dried in vacuo advantageous
In wood internal combination water drying but for the drying effect unobvious of timber Free water, moisture is also undergone in drying process
One process by liquid water to vapor absorbs the latent heat of vaporization and so that energy consumption is higher in drying process.In hot conditions
Under, since moisture gradient is big inside and outside timber so that drying stress is big, finally results in and is susceptible to dry lack in drying process
It falls into, the especially drying of some hard broadleafs.
Currently, mainly using following two drying modes in drying of wood field：I.e. traditional conventional kiln drying (kd) and advanced
Vacuum drying.For traditional conventional kiln drying (kd) since arid cycle is long, thermal energy waste is serious, while in the drying process, can not be right
Heating rate, rate of drying control effectively.Although existing vacuum dryer is in the side such as arid cycle and dry mass
Face is all advanced in traditional conventional kiln drying (kd), but cannot be guaranteed the flatness after the drying of wood in the drying process, and there are still warpages
The phenomenon that.
In summary, present timber dryer is primarily present defect below：Timber after drying can still go out
The phenomenon that existing warpage, drying efficiency is relatively low.
Therefore, we it is necessary to designs again to prepare a kind of novel timber dryer, with this come solve it is existing such as
Modern the problems of timber dryer in the market, preferably to be adapted to society with this has=demand with relevant department,
Preferably to push the development of China's wood industry with this.

Electric energy, starts positive pressure fan thermal energy is sent in hothouse and carry out the drying of wood, is recycled to thermal energy too by negative-pressure air fan
Positive energy heat collector, carries out recycling for thermal energy, reduces drying of wood energy consumption；
（2）Rotary vacuum pump, which is arranged, in the present invention to be in vacuum work into performing local vacuum processing, hothouse top at the top of hothouse
When making state, dry hatchway cover sink, and drying hatchway cover bottom by spring squeezes wood to be dried, and timber is being done
It is pressurized in dry process, ensure that the flatness during its drying, the timber after drying is not in warping phenomenon, vacuum state
It releasing, bullet restPoses on spring, and alternating floor places one block of timber when the drying of wood, ensures that uniform thermal power penetrates timber,
Evenly drying；
（3）Thermal energy is sent to hothouse by positive pressure fan by positive pressure in the present invention, and a part of thermal energy storage to regenerative chamber stores
Heat storage tank is set in hot cell, when drying of wood set temperature is not achieved in dry indoor temperature, storage to the thermal energy in heat storage tank
It is discharged, dry indoor heat is supplemented, another part thermal energy carries out negative pressure recycling by negative-pressure air fan, in hothouse
A uniform heat energy circulating system is formed, uniform thermal power suffered by timber surrounding will not cause hot-spot, and affected by force
The cracking for causing timber, the steam evaporated are discharged by exhaust hole, and thermal energy is fully utilized, and improve drying of wood efficiency.
