Description

11 The invention relates to non-ferrous metallurgy, in particular, to equipment for producing non-ferrous metals by electrolysis of aqueous solutions, namely, devices for fixing electrodes in electrolyzers. Insulators are known for fixing the distance between the electrodes in an electrolyzer rotating on the Cl axis. A disadvantage of insulators is that the electrodes are not sufficiently isolated from each other. The closest to the invention to the technical essence and the achieved result is an isolator for fixing the distance between the electrodes with a hole for rotation. The insulator is made in the form of a body of rotation formed by two truncated cones with a common large base with a hole along the axis of rotation, on the outer surface of which teeth 21 are made along the largest meter. The disadvantage of the known insulator is that it allows the overgrowth of the hole in the anode web close to the isolator, after which it stops rotating with. In this case, the teeth are quickly deteriorated due to abrasion or spallation. The insulator is overgrown with sludge, which leads to a short circuit of the electrodes through the sludge. The purpose of the invention is to reduce power consumption by reducing the number of short circuits. The goal is achieved by the fact that the insulator for fixing the distance between the electrodes with a hole for rotation is made in the form of a cross or a hypotrochoid with a hole in the center of the rod. Making an insulator in a cross of a cross or of a hypotrochoid, and not in the form of a body of revolution, makes it possible to more completely clear the hole in the web 9 of the anode from the cuttings, in which it rotates. In addition, the insulator does not overgrow with a slurry of chz because of the large distance between the bulbs and the direct or obtuse angle between them. Thus, the sludge particles do not form a solid mass and easily fall off when the insulator rotates. Therefore, the insulator does not coalesce with the slurry in the hole of the anode web and its protrusions clear this hole during rotation. Due to the absence of fouling, there is no breakage of the insulator and short bursts through the slime. FIG. 1 shows an isolator, complete with an equal shoulder cross; in fig. 2 - the same, in the form of an unequal cross; in fig. 3 - also in the form of a hypotrochoid in FIG. 4 and 5 are sections A – A, which may have all three reduced insulators; in fig. 6 - installation of an isolator on the anode. The material for the manufacture of the insulator can be any hard and acid-resistant plastic, acid-resistant viscous glass or glazed porcelain. The axis is made of anode material. together with the insulator 2 put on it, it is inserted into the hole 3 in the anode 4 fabric and welded to the anode. In the process of cutting and planting the cathodes, the insulator 2 is rotated by touching the bottom or side of the cathode, which cleans the hole in the web and it cleans itself. Compared to the known, more reliable insulation by the proposed insulator will reduce the number of short circuits and, thus, reduce electricity consumption by 3-6 "Bth per ton of zinc.
