Description

Technical Field

[0001] The utility model relates to the technical field of scientific and technological wood drying devices, in particular to a high-frequency scientific and technological wood drying device. Background Art

[0002] Technological wood is a new type of all-wood decorative material with superior performance, made of ordinary wood (fast-growing wood) and using the principle of bionics. It is produced by various modified physical and chemical treatments of ordinary wood and fast-growing wood. Compared with natural wood, it is almost not bent, cracked or twisted. Its density can be controlled artificially, and the product has good stability. During the processing, it does not have the waste and value loss of natural wood processing, and can increase the comprehensive utilization rate of wood to more than 86%. Technological wood is not solid wood, but a synthetic composite product.

[0003] For example, a high-frequency high-tech wood drying device disclosed in Chinese patent publication number CN109278143A installs a high-frequency heater to perform high-frequency heating on the glue to achieve overall balanced heating. The curing time is shortened from the original 5-15 days to 1-4 days, which greatly improves the effect and efficiency of heating and curing. By setting an insulating plate, high-frequency heating is only applied to the high-tech wood through the insulating plate to prevent high-frequency heating of places other than the high-tech wood, thereby saving energy and improving efficiency. At the same time, the insulating plate provides a certain insulating effect to prevent the electrode plate from contacting the steel plate to generate high frequency, thereby ensuring work safety.

[0004] First of all, the heating principle of the high-frequency heating machine is mainly that the magnetic beam penetrates the entire heated object, and a corresponding large eddy current will be generated inside the heated object in the opposite direction of the heating current. Due to the existence of resistance in the heated object, a lot of Joule heat will be generated, causing the temperature of the object itself to rise rapidly. However, when this heating method is used to heat high-tech wood, due to the poor electrical and magnetic properties of high-tech wood, the high-frequency heating machine needs to add additional auxiliary processing modules to achieve the ideal heating and drying effect.
