Description

Изобретение относитс  к технике сушкк в электрическом поле токов высокой частоты древесины и древесных материалов и может быть использовано в деревообрабатывающей промышленности.The invention relates to the technique of drying in the electric field of high frequency currents of wood and wood materials and can be used in the woodworking industry.

Цель изобретени  - интенсификаци  процесса сушки и снижение энергозатрат.The purpose of the invention is to intensify the drying process and reduce energy consumption.

На фиг.1 показана установка дл  суп1ки древесины согласно изобретению, вид сверху; на фиг.2 - то же, поперечный разрез; на фиг.З - формы кривых питаюшего напр жени .Figure 1 shows the installation for sup1ki wood according to the invention, top view; figure 2 is the same cross section; FIG. 3 shows the shape of the feeding voltage curves.

Между основпы.ми электродами 1 и 2 устанавливают заготовки 3, к торцам которых креп тс  вспомогательные торцоные электроды 4 и 5.Between the main electrodes 1 and 2, set the workpiece 3, to the ends of which the auxiliary end electrodes 4 and 5 are attached.

На основные электроды 1 и 2 подаетс  высокочастотное переменное нанр жеиие (фиг.З, позици  6). К торцовым электродам 4,5 подаетс  высокочастотное напр жемте одной пол рности (фиг.З, позици  7), синхро- ной частоты; сдвиг по фазе ip равен :0°.A high frequency alternating voltage is applied to the main electrodes 1 and 2 (FIG. 3, item 6). The end electrodes 4.5 are supplied with a high-frequency voltage of one polarity (Fig. 3, position 7), the synchronous frequency; phase shift ip is equal to: 0 °.

На фиг.З также обозначено: U - питл.ю- шее напр жение; w - кругова  частота; врем .FIG. 3 also indicates: U is the maximum voltage; w is the circular frequency; time

Основные э.лектроды 1 и 2 располож1;пы под углом к движению высччпиваемого материала (фиг.).The main electrodes 1 and 2 are located1; they are at an angle to the movement of the material to be extracted (Fig.).

Проводилась cyuiKa древесного материала (порода  сень) толщиной 40 мм, ;.линой 400 .мм, начальна  влажность 60%. На основные электроды подавалось высокочастотное напр жение частотой 13,56 МГц. На торцовые электроды подавалось высокочастотное панр жеппе одной пол рности (фиг.З) частотой 6,78 МГц. Количество высокочастотных электродов нагрева пластин составл ет три нары. Нагрев высушиваемого материала до 60-70°С. Конечна  влажность древесины 10%. Объем выcyпJивaeмoгo материала 0,5 м . Врем  cynjKH 18 ч.A cyuiKa of wood material (rock canopy) with a thickness of 40 mm was carried out; 400 mm line, initial humidity 60%. A high-frequency voltage of 13.56 MHz was applied to the main electrodes. A high-frequency pan of one polarity (Fig. 3) with a frequency of 6.78 MHz was applied to the end electrodes. The number of high frequency plate heating electrodes is three bunks. Heating of the dried material to 60-70 ° C. The final moisture content of wood is 10%. The volume of your material is 0.5 m. Time cynjKH 18 hours
