配制蓄电池电液所用浓硫酸,一般盛在坛内,重约数十公斤。因浓硫酸腐蚀性强,飞溅出来对工作人员皮肤、衣服造成危害。用一般方法提取既不方便又笨重,而且有一定危险。为此,我们做了一个气压抽取装置,使用方便,结构简单,便于定量抽取并做到安全生产。该装置如附图所示。充气金属管4可用拖拉机废 Concentrated sulfuric acid used in the preparation of battery electric liquid, generally Sheng in the altar, weighing about tens of kilograms. Due to the strong corrosive concentrated sulfuric acid, splashed out on the staff of the skin, clothing hazards. It is inconvenient and cumbersome to extract using the general method, and there is some danger. To this end, we made a pressure extraction device, easy to use, simple structure, easy quantitative extraction and safe production. The device is shown in the drawing. Inflatable metal tube 4 can be used tractor waste
