专利说明:
The invention relates to a coated anode for the electrolytic production of metals, the working surface of which is formed parallel to each other by rods electrically connected to a current-supply busbar, spaced apart from one another. A known anode for the electrolytic production of metals, made of titanium, placed in the same plane parallel to each other with coated rods connected to a current-carrying bus tlH. The disadvantages of this anode should be attributed to high consumption, electricity and high cost of construction. The closest to the invention according to the technical essence and the achieved result is an anode for electrolytic production of metals, made of titanium, placed in one plane parallel to one another with coated rods connected to the current-supply bus, with the rods made in the form of strips, rods, semi-cylinders or V-shaped elements; working rods are made of platinum and / or oxides of platinum and / or electrically conducting non-stoichiometric oxide and / or non-precious metal and / or its oxide and / or mixtures thereof, and at least one plate of rectangular cross section is welded across D21 rods. The disadvantages of the known anode should include a large power consumption. The purpose of the invention is to reduce power consumption. The goal is achieved by the fact that the anode for electrolytic production of metals, made of titanium, are arranged in one plane parallel to each other with coated rods connected to a current-carrying bus, while the rods are made in the form of strips, rods, half-cylinders or U-shaped elements forms, the working coating of the rods is made of platinum and / or oxides of platinum, and / or electrically conducting non-stoichiometric oxide, and / or non-precious metal, and / or its oxide, and / or their mixtures and at least one plate The rectangular section is welded across the upper layers, the ratio of the total surface of the rods A to the occupied: the entire core structure of the surface p is 6 f / vll 2, the ratio of the short and long sides of the rectangular cross section of the rods is 1: (2-10) / width of each rod to . the distance between the axis of symmetry of two adjacent rods is 1: (4-6), the rod width parallel to the arrangement plane is 0.5-0.25 mm, the depth of the rod measured 5 perpendicular to the anode plane is 5-25 mm and the distance between two adjacent rods is A 2 mm. Figure 1 shows the plane of the anode, top view; on Fig. 2 is a view of the structure parallel to the plane of arrangement; in FIG. 3, node 1 in FIG. 2; figure 4 - node fl in figure 1. 5 On the support brackets 2 on the edge of the loading window of the electrolysis tank 1 there is a current supply bus 3, connected by a contact bus 4 to a current source. Tokopodvod shcha Q bus 3 carries a series of rods 5, representing the working surface of the anode. Rods have a rectangular cross-section of a width of a width of T. Depth. In this case, the rods 5 are oriented TaKHiJt in the way that their depth T passes perpendicular to the plane of the location of the rods. The surface occupied by the rods is determined by the length of the rods Lj and the distance L $ between the outer sides of the two outer rods of the anode structure. The rods 5 are located with distance A in light of one relative to the other. 5 The electrical and mechanical connection of current-carrying tires, made, for example, of copper, with rods 5, made of, for example, coated with titanium, is shown in FIG. 3. The busbar busbar 3 and the rods 5 are located in the same plane so that the upper and end surfaces of the rods 5. adjacent to the bottom surface of the connecting cable 3. The current connecting bus 3 is connected to the rods 5 by two connecting strips b located on both sides of the current leading busbar, parallel to the current leading bus and precisely made of titanium with a coating. The connecting strips 6 are fastened with screws 7ok and nuts 76 to the busbar 3. The rods 4 are connected to the connecting strips 6 by spot welding 8. To further tighten the anode structure, several transverse rods are connected by spot welding to the rods 5 0 9, made in exactly the same way with coated titanium. In this case, successively located river rods 9 are alternately arranged on one or the other side of the plane of the location of the rods 5. Example. The rods 5 have a length J, 5J equal to 1170 mm, while their width B is 2 mm, and the depth T is 12 mm. The clear distance A between two adjacent rods 5 is 8 mm. The total LS length of the anode structure is 852 mm. 82 rods are provided. The anode is designed for a current of 600 A, respectively, for a density of -current on the anode side of 355 A / m (p). With a current of 600 A in the anode arises. with a 4th voltage drop of only about 100 mV. The design of the anode is very tough and durable. This is a result of not only the connection of the rods 5 with the busbar 3 by means of connecting strips 6 and spot welding of the rods with these connecting strips 6, but also by the additional arrangement of transverse rods 9 having a diameter of 4 mm. Thus, each plate rod 5 is fixed with seven welding points, ki. The anode is simple in design, relatively cheap to manufacture due to the small amount of material has a very large geometric surface. It weighs about 12 kg without current lead 3. The total surface of the rods l. To which the coating is applied is. including contacts, about 3 m. The working surface of the anode, i.e. The surface immersed in the electrolyte is approximately 2.4 m, which at 600 A gives a value (anodic 5 current density) of about 250 A / m% (}. The actual physical anodic current density resulting from the extremely large surface of the coating is This is only 5% of the value of 3. Based on this and the catholytic efficiency of the active components of the coating, a constant low oxygen pressure at the anode is obtained over a long period of time. 5 operation. The coating on the surface of the anode protruding from the bath serves to protect the titanium parts of the anard from corrosion, 0 The current load of the copper current-carrying bus 3 is relatively small (about 0.8 A / mm with a current of 600 A on the anode) making it possible to make new holes in the current-carrying bus 3 at a length of L 85 852 mm. Each hole 6a in the connecting strip 6 receives a current. around 33 A. Due to this small partial current in the contact zones and good contact coverage, the fall does not remain constant in these areas for a long service life. 5- Phage.g FIG.
