Description

Изобретение относится к технике сушки пиломатериалов и может быть использовано в деревообрабатывающей, мебельной и других отраслях промышленности.The invention relates to techniques for drying lumber and can be used in woodworking, furniture and other industries.

По основному авт.св. № 623075, известна установка для сушки пиломатериалов , содержащая сушильную камеру с загрузочной дверью и вентилятор, в которой по всей ширине камеры размещены водораспылители, при этом воздуховоды расположены над сушильной камерой на уровне высоты двери Г1] .By main auto No. 623075, there is a known installation for drying lumber containing a drying chamber with a loading door and a fan in which water sprays are placed across the entire width of the chamber, while the air ducts are located above the drying chamber at the level of door height G1].

Недостаток известной установки малая эффективность использования энергии внешней среды, например солнечной энергии.A disadvantage of the known installation is the low efficiency of the use of environmental energy, such as solar energy.

Цель изобретения - интенсификация процесса сушки и повышение экономичности путем использования солнечной энергии.The purpose of the invention is the intensification of the drying process and increase efficiency by using solar energy.

Поставленная цель достигается __ тем, что верхняя часть воздуховода выполнена прозрачной, а нижняя - в виде экрана черного цвета.This goal is achieved __ by the fact that the upper part of the duct is made transparent, and the bottom - in the form of a black screen.

На фиг. 1 приведена установка, продольный разрез; на фиг. 2 - то же, вид сбоку. 30In FIG. 1 shows the installation, a longitudinal section; in FIG. 2 is the same side view. thirty

Установка для сушки пиломатериа~ лов содержит камеру, снабженную вентилятором 1, внутри которой помещены штабеля 2 пиломатериалов. С фасада камера снабжена металлическими дверями 3 для загрузки и выгрузки штабелей 2. Верхняя часть камеры снабжена экраном 4 черного цвета, над которым размещено прозрачное перекрытие 5. Таким образом экран 4 и перекрытие 5 образуют внутренний циркуляционный’ канал 6 воздуховода. Торцовые боковые стены 7 камеры выполнены наклонными, причем таким образом, что образуют боковой канал 8 воздуховода, который сообщается с циркуляционным каналом 6. В нем по всей ширине камеры размещены водораспылители 9.The installation for drying lumber ~ contains a chamber equipped with a fan 1, inside of which stacks of 2 lumber are placed. From the facade, the chamber is equipped with metal doors 3 for loading and unloading stacks 2. The upper part of the chamber is provided with a black screen 4, above which a transparent ceiling 5 is placed. Thus, the screen 4 and the ceiling 5 form an internal circulation ’channel 6 of the duct. The end side walls 7 of the chamber are made inclined, so that they form a side channel 8 of the air duct, which communicates with the circulation channel 6. In it, water sprays 9 are placed throughout the entire width of the chamber.

Установка работает следующим образом.Installation works as follows.

Штабеля 2 пиломатериалов, размещенные на тележках 10, при открытых дверях 3 камеры закатываются внутрь нее. После размещения всех штабелей 2 в камере двери 3 закрываются и включают вентиляторы 1, которые нагревают воздух поперек штабеля 2. Затем поток воздуха направляется в канал 8, откуда поступает в циркуляционный .'канал 6, выполненный в виде горячего ящика. Такое исполнение верхней части воздуховода обеспечивает использование солнечной энергии для нагрева циркулирующего воздушного потока. Основным регулируемым параметром процесса сушки пиломатериалов в установке является относительная влажность воздуха. Эта регулировка осуществляется водораспылителями 9.Stacks of 2 lumber placed on carts 10, with the doors open 3 cameras roll inside it. After placing all the stacks 2 in the chamber, the doors 3 are closed and the fans 1 are turned on, which heat the air across the stack 2. Then the air flow is directed to the channel 8, from where it enters the circulation. Channel 6, made in the form of a hot box. This design of the upper part of the duct allows the use of solar energy to heat the circulating air flow. The main adjustable parameter of the drying process of lumber in the installation is the relative humidity. This adjustment is carried out by water sprays 9.

При размещении вентиляторов 1 в' средней части камеры по всей её ширине с целью равномерности просушки штабелей 2 левой .и правой частей камеры вентиляторы 1 снабжены реверсом, что обеспечивает периодическое изменение направления потока воздуха При этом регулирование относительной влажности врздуха в камеры осуществляет водораспылитель 9, установленный на нагнетательном участке каналаWhen placing the fans 1 in the middle part of the chamber along its entire width in order to uniformly dry the stacks of the left 2 and the right parts of the chamber, the fans 1 are equipped with a reverse, which provides for a periodic change in the direction of air flow. on the discharge section of the channel

Claims

The invention relates to the technique of drying lumber and can be used in woodworking furniture and other industrial areas. According to the main auth. No. 623075, a well-known plant for drying lumber, containing a drying chamber with a loading door and a fan, in which water dispensers are placed across the entire width of the chamber, while the air ducts are located on the drying chamber at the height of the MS door. The lack of a known installation is low energy efficiency of the external environment, such as solar energy. The purpose of the invention is to intensify the drying process and increase economy by using solar energy. The goal is achieved by the fact that the upper part of the duct is made transparent and the lower part is in the form of a black screen. FIG. 1 shows the installation, longitudinal section; in fig. 2 - the side view. The sawmill drying unit contains a chamber equipped with a fan 1, and a stack of 2 sawn timber is placed inside the KOTOpofi. From the front, the chamber is equipped with metal doors 3 for loading and unloading headquarters 2. The upper part of the chamber is equipped with a black screen 4, above which is a transparent overlap 5. Thus, the screen 4 and the overlap 5 form the internal circulation duct 6 of the duct. The end walls of the side walls 7 of the chamber are inclined, and in such a way that they form the side channel 8 of the air-water, which communicates with the circulation channel 6. Water-sprayers 9 are placed across the entire width of the chamber. The installation works as follows. A stack of 2 sawn timber placed on the carts 10, with the doors open, 3 chambers are rolled inside it. After placing all the stacks 2 in the chamber, the door 3 is closed and the fans 1 are turned on, which heat the air across the stack

2. Then the air flow is directed to the channel 8, from where it enters the circulation one. channel 6, made in the form of a hot box. This design of the upper part of the duct provides the use of solar energy to heat the circulating air flow. The main adjustable parameter of the process of drying lumber in an installation is relative air humidity. This adjustment is carried out by water-spraying 9. When fans 1 are placed in the middle of the chamber across its width in order to evenly dry the stacks 2 of the left and right parts of the chamber, fans 1 are provided with a reverse, which provides a periodic change in the direction of air flow. moisture in the chambers is performed by a water-sprayer 9 installed in the discharge section of the channel 8. By making the upper part of the duct transparent, and the lower I .. o6 / / fO S 2 as a screen 4 the black color, the circulating air flow during the daytime is heated by using solar energy, which increases the efficiency of the installation and intensifies the process of drying the stacks of lumber in the chamber. Claims of the Invention Plant for drying lumber according to ed. 623075, characterized in that, in order to intensify the drying process and increase efficiency by using solar energy, the upper part of the duct is made transparent and the lower part is in the form of a black screen.
