    • In electrolytic apparatus comprising cell chambers through which is passed an electrolyte and in which sets of anode plates are provided, each of which are connected to current-feeding center pins, and the mutually staggered electrode plates protrude into the gaps between plates having the opposite polarity. To ensure a simple, quick and reliable installation and removal of the anode plates, the center pin is provided with contact straps, which are spaced apart in the longitudinal direction of the pin and serve to secure the anode plate. The contact straps are suitably spaced about 180.degree. apart and have at least one opening, which consists preferably of a tapped bore.The electrolytic apparatus is used in processes of producing alkali chlorate by the electrolytic decomposition of aqueous alkali chloride solutions.
    • 在电解设备中,包括通过电解质的电池室,其中设置有一组阳极板,每个阳极板连接到电流馈送中心销,并且相互交错的电极板突出到具有相反极性的板之间的间隙中 。 为了确保阳极板的简单,快速和可靠的安装和拆卸,中心销设置有接触带,其沿销的纵向方向间隔开并用于固定阳极板。 接触带适当间隔约180°并具有至少一个开口,其优选地由螺纹孔组成。 该电解装置用于通过电解分解氯化碱水溶液来生产碱式氯酸盐的方法。
