以往,我厂模型車間因为木材儲备量少、需用量大,往往湿度較高的木材,得不到自然或人工干燥,就用来生产了。所以模型很容易变形,严重地降低了它的使用寿命。根据职工的建议,我們設計了一个經济实用結構簡單的木材干燥爐。 爐子的构造如附图。它是由內外兩层普通的夾牆和夾层的鋼筋水泥頂所組成。木料擱在固定的角鋼支条上,坑中用普通块煤作燃料,所产生的热量,經过下层气孔,进入夾牆中,再由此分流,一股經上层气孔进入爐膛,一股由夾牆經烟囱到爐外。进入爐膛內的热气把木材中的水份蒸发,經过
In the past, I plant the model workshop because of the small amount of timber reserves, the amount required, often high humidity wood, not natural or artificial drying, it is used to produce. Therefore, the model is easily deformed, seriously reducing its service life. According to the staff’s suggestion, we designed a economical and practical structure of simple wood drying furnace. The structure of the stove is shown in the attached figure. It is composed of two layers of ordinary internal and external sandwich wall and mezzanine reinforced concrete roof. Wood resting on a fixed angle bar, the pit with ordinary lump coal as fuel, the heat generated, through the lower stomata, into the folder wall, then the diversion, an upper stomata into the furnace, a by the Wall through the chimney to the furnace. The hot air entering the hearth evaporates the moisture in the wood and passes
