     SAFE ANODE FOR ELECTROCHEMICAL CELL. DESCRIPTION. OBJECT OF THE INVENTION The following invention, as expressed in the statement of the present specification, refers to a safe anode for electrochemical cell, being of the type of vertical anodes used in electrochemical cells and in particular of electro obtaining metals, the anodes being constituted by a hanging structure, based on a 10 horizontal conductive feed bar and vertical distribution bars connected to the feed bar, whose distribution bars are defined by a copper or aluminum core, and, an outer layer or envelope of titanium. Starting from this conventional embodiment, a first objective of the invention is that the electrical connection between the vertical busbars and the anodic plate or plates of coated titanium is materialized by means of respective adapter elements comprising a current limiting assembly, with in order to avoid short circuits that destroy or cause damage to the anodic plates of coated titanium. A second objective of the invention is to reduce the dispersion of the emission of oxygen bubbles with sulfuric acid, channeling them through the central part of the anode, for which the anode plates are arranged in an inclined position with respect to the vertical plane defined by the vertical bars of distribution, allowing to have a chimney effect that drags them, facilitating their collection by a collector and avoiding the harmful “acid fog” and its serious environmental effects. Thus, an important economic advantage is obtained, since, on the one hand, destruction or damage to the anodic plates of coated titanium is avoided and, in the event of a short circuit, the affected plate is not destroyed and the rest of the plates continue in operation. 30 APPLICATION FIELD. A safe anode for electrochemical cell is described herein, being applicable in electro-obtaining cells of metals, such as copper. 35BACKGROUND OF THE INVENTION In the first place we can indicate that the electrochemical containers, tanks or cells are filled with an electrolytic solution composed among others by the metal to be deposited and in which a plurality of pairs of anodes / cathodes are immersed, in alternating position, that being 5 Electrically powered the metal is deposited in the cathodes. Thus, by using vertical anodes in said electro-obtaining metal cells, said vertical anodes are constituted by a hanging structure, based on a horizontal conductive feed bar and vertical distribution bars connected to the feed bar, whose bars Distribution are defined by a copper or aluminum core, and a titanium outer shell or shell. In this way, the anodic plates of coated titanium are electrically connected to the busbars being on its surface where the anodic operation of electrolysis is performed. Thus, conventional anodes have multiple combinations in terms of the number of vertical bars per horizontal feed bar. As indicated, the conventional vertical bars used in electro-metal processes are bimetallic bars with a copper or aluminum core and a titanium outer layer or skin. Copper or aluminum has the low electrical resistivity necessary for the efficient transmission of high currents and titanium protects the chemical attack of the electrolyte to copper or aluminum, while allowing the connection of anodic plates of titanium coated to these vertical bars . In this way, the anodes and in particular the anodic surfaces used in the processes of electro-obtaining metals, in order to obtain optimum performance and maximum capacity, operate at a short distance from the cathodes and have a large area in relation to at the small anode-cathode distance, such as an area of 100x100 centimeters with a separation of 5 cm. This, inevitably, introduces the risk that in the event of any deformation or alteration of the planarity at any point of the cathodic surface, an anode-cathode electrical contact or a short circuit occurs. 35 Cathodic surfaces are unstable by nature, since they modify their thicknessquickly in the production process itself and, in addition, an increase in cathode thickness at a single point on its surface, implies a shorter anode-cathode distance that reduces electrical resistance and, applying Ohm's law, an increase in ionic current at that point. 5 By increasing the ionic current or deposition, we increase the thickness of metal deposited at these points, so that these events clearly present a positive feedback scheme that, as is known, are intrinsically unstable processes that in these cases end up establishing an anode-cathode contact. that is the short circuit. 10 On the other hand, any existing alignment or mechanical deformation error will also produce direct anode-cathode contact, that is, the short circuit. Once the direct electrical contact between the anode and the cathode is established, the electrochemical potential barriers between the electrolyte and the anode disappear and the relatively high resistance of the electrolyte will also be removed. In these circumstances, the electric current trips at unacceptable values, damaging or destroying the coated titanium anodic plate while producing high performance losses. On the other hand, we can indicate that in the process of working of the anodes in a cell of 20 electro-obtaining metals, and in particular copper, oxygen bubbles with sulfuric acid are produced, a phenomenon known as “acid mist”. This “acid fog” creates a serious problem of environmental pollution and can directly affect the health of the plant operators, forcing the use of masks in the cell rooms and the deterioration of the environment in the area where the plant. 25 This is because the electrolyte is mainly formed by a solution of sulfuric acid and copper sulfate. The anode in its normal electrolysis process produces oxygen bubbles that are contaminated by housing sulfuric acid, a large part of these bubbles leave the electrolyte and become part of the surrounding atmosphere in what is called acid fog. On the other hand, a current limiter is a device that reacts and cancels any current above a certain value, this value is a characteristic of the particular device or model. 35A very familiar example is the fuse of our houses, when we face a short circuit or direct contact of the two wires of the network, the fuse trips and disconnects leaving us in the dark. Then we must reset or replace the fuse to have the lighting. We use this example to explain the concept of rearmament and extend to the possibility that automatically after a while, if the physical short circuit has disappeared and without the need for our intervention, the lights will work again, we will say that our fuse is Auto reset or auto reset, they are also called auto reset. There are two ways to protect ourselves from short-circuiting, one is canceling or forcing the current to zero and the other is modulating the current to allowable low values. We consider both cases as current limiters, but we will call the first all or nothing digital and the analog seconds. Likewise, we can cite the patent document WO 2015/079072 in which an anodic structure for electrodeposition metal cells is described, comprising a horizontal support bar and vertical bars, covered with plastic or epoxy to which they fix anodic plates, called sub-meshes with an area of 25 to 225 cm2, to which power is supplied by means of respective wiring and / or printed circuits that are protected by insulating structures and that are installed inside 20 Vertical bars coated with plastic or epoxy. DESCRIPTION OF THE INVENTION A safe anode for electrochemical cell is described herein, being of the type of vertical anodes constituted by a hanging structure based on: - a horizontal conductive power bar, and; - vertical distribution bars connected to the feed bar, whose distribution bars are defined by: o a copper or aluminum core, and; 30 or a layer or outer shell of titanium, and; - at least one coated titanium anodic plate associated with the vertical distribution bars, so that the secure anode incorporates an adapter element comprising a current limiting assembly, arranged between at least one of the vertical distribution bars, 35 and at least one anodic plate of coated titanium, whose adapter element isconnecting the corresponding vertical distribution bar with the coated titanium anodic plate fixed thereto. In a practical embodiment of the invention, the secure anode adapter element is defined by a current limiting assembly that is fixed, directly, to a vertical distribution bar 5 and to an anodic coated titanium plate, connecting the vertical distribution bar with the anodic plate In this way, the adapter element is defined by the current limiting assembly itself. In a first practical variant of the invention, the secure anode adapter element is defined by a titanium plate carrying a current limiting assembly, the titanium plate being fixed to a vertical distribution bar and the current limiting assembly. fixes the corresponding anodic plate of coated titanium, whose 15 anodic plate has an area of 250 to 1670 cm2. In a second variant of practical implementation of the invention, the secure anode adapter element is defined by a titanium plate bearing two current limiting assemblies, one at each end, the titanium plate being fixed to a vertical distribution bar and The pair of current limiting sets is attached to the corresponding anodic plate of coated titanium. Likewise, the secure anode adapter element comprising, at least, a current limiting assembly, is fixed to the corresponding vertical distribution bar defining a slight inclination with respect to a vertical plane, inclination which will also present the anode plate of coated titanium attached to it. The anode adapter elements comprising at least one current limiting assembly may have a different magnitude in their slight mounting inclination, the anode plates associated with them being also, according to different inclinations with respect to a vertical plane. On the other hand, the anode adapter elements comprising at least one current limiting assembly, and having different magnitude in their slight inclination of assembly, are fixed, along the corresponding second vertical bar ofdistribution, with an increasing magnitude from bottom to top, causing a chimney effect on the upward flow of oxygen and acid bubbles. The titanium plate, which forms the adapter element, can have a tubular configuration incorporating in its internal central part a current limiter 5 associated with at least one broken plate that protrudes outside and to which the corresponding anodic plate is fixed. Likewise, the titanium plate, which forms the adapter element, can have, interposed therein, a block of epoxy resin or the like in which a current limiter is embedded. Since the survival of the anode is usually affected by the aforementioned short circuits and not by other causes, we define that an anode is safe when it is able to withstand the short circuits without suffering relevant damage and remaining operational. 15 Thus, the current limiter assembly, which forms the adapter element, and which integrates the current limiter, is defined by a box that houses a titanium plate, insulated by an insulating means of the container box, in which insulating means incorporates two current limiters themselves, connected by one terminal to the intermediate titanium plate and by the other terminal 20 to the box. Also, the current limiter assembly, which forms the adapter element, and which integrates the current limiter, is defined by a pair of bimetallic pieces, titanium / copper, faced by the copper surface, with the interposition of a current limiter in yes, constituted by a polymer layer and respective copper sheets on both sides, having produced a transverse perimeter and central recess corresponding to the width of the copper of both facing bimetallic pieces, filling said recess with an epoxy resin or similar insulator. In order to complement the description that is going to be carried out below, and in order to help a better understanding of the characteristics of the invention, a descriptive set of drawings is attached to the present specification, in whose figures it is illustrative and not limiting, the most characteristic details of the invention are represented. 35 BRIEF DESCRIPTION OF THE DESIGNS. Figure 1.

Figures 16, 17 and 18 show respective front, elevation and plan views of a practical embodiment in which the anodic plates are mounted defining a slight inclination with respect to a vertical plane. Figures 19 and 20 show a front view and a plan view of a practical embodiment in which a series of anodic plates of coated titanium are fixed to a second vertical distribution bar, being able to observe how the anodic plates have a slight inclination , whose degree of inclination increases from the inferior to the superior, that is, from bottom to top obtaining a chimney effect. Figure 21 shows a side elevation view of the execution of the previous figure in which the path followed by the bubbles is observed by the chimney effect that creates the inclined arrangement of the anodic plates. DESCRIPTION OF A PREFERRED EMBODIMENT. 25 In view of the aforementioned figures and in accordance with the numbering adopted, we can observe how starting from a conventional configuration in which an anode 1 is constituted by a hanging structure based on a conductive feeding bar 2 and a series of vertical bars of distribution 3 to which at least one anodic plate 4 of coated titanium is fixed (from here we will simply call them anodic plate 30), being able to observe in figure 1 of the designs as, in said practical execution, the anode has two anodic plates 4. In said conventional embodiment the anodic plates 4 are fixed to the vertical distribution bars 3 by welding points 5, as seen in Figure 2 of the designs. Starting from the conventional configuration described, a first object of the invention isbased, on the incorporation of an adapter element 6 comprising, at least, a current limiting assembly 7, as seen in Figure 4, through which the connection or power supply to the anode plates 4 is established from the corresponding vertical distribution bar 3. 5 Thus, according to figures 4 and 5, in a practical embodiment the adapter element 6 comprises a current limiting assembly 7 and which will be fixed directly to a vertical distribution bar 3 and an anodic plate 4, so that the power supply reaches the anode plate through the current limiter 7 from the vertical distribution bar 3. In this embodiment the current limiter assembly 7 itself acts as an adapter element 6. On the other hand, according to Figures 6 and 7 of the designs, in a first variant of practical execution the adapter element 6 is defined by a titanium plate 8 which by one of its ends was fixed aa a vertical distribution bar 3 and at its other end incorporates a current limiting assembly 7, while, according to figure 8 of the designs, in a second variant of practical execution the adapter element 6 is defined by a titanium plate 8, fixed to a vertical distribution bar 3, and which at both ends has two current limiting sets 7 to which the respective anodic plate 4 will be fixed, the power supply reaching the anodic plates 4, from the bar vertical distribution 20 3, through the titanium plate 8 and the corresponding current limiter 7. The current limiter assembly, preferably self-assembling, will be executed by any mechanism available in the industry, that is, Bi-metallic switch, 25 digital fuses with automatic reset, analog fuses with automatic reset, transistors in cut or regulation, etc. Thus, by way of example and according to figures 8, 9 and 10 of the designs, we can indicate that a first type of current limiting assembly 7 to be used as a conformant 30 of the adapter element 6, can be defined by a pair of parts 9 bimetallic, titanium / copper, faced by the copper surface, with the interposition of a current limiter 10 itself, consisting of a polymer layer and respective copper sheets on both sides, having produced a corresponding perimeter and transverse central recess to the width of the copper of both bimetallic pieces 9 facing each other, 35 filling said recess by an epoxy resin 11 or similar insulator. In this way, in figure 8 of the designs it can be seen how in relation to the current limiting assembly 7 the two striped parts would correspond to the copper of the bimetallic piece 9 and the contour to them would correspond to the perimeter and transverse central recess which, at the junction of the two bimetallic pieces 9 with the interposition of the current limiter 5 itself, would be filled with an epoxy resin 11 or other insulating material. A second type of current limiting assembly 7, according to FIG. 11, 12 and 13 of the designs, may be constituted by a titanium case 12 in which one end of the titanium plate 8 is housed with the interposition of an insulating means 13 and in which insulating means 10 incorporates two current limiters 10 itself, so that, preferably, it will incorporate two titanium boxes 12, as seen in figure 13 of the designs, one at each end of the titanium plate 8, which will be connected, by one terminal, to the titanium plate 8 and, by its other terminal, to the titanium box 12, that is, the power supply flow would be vertical distribution bar 3 - plate of titanium 8 - current limiter 15 10 - box of titanium 12 - anodic plate 4. We comment that we omit the explanation for extension to 3, 4… limiters per adapter element because we consider it obvious from the cases presented of 1 and 2 limi tadores per adapter element. The insulating medium 13 can be a layer of epoxy resin or plastic material or any other equivalent material. Logically, the structure described relative to the adapter element, likewise, can have other executions equivalent to those described, and, thus, in Figure 14 of the 25 designs we can see how the titanium plate 8, forming the adapter element 6, can present a tubular configuration and housing inside the current limiter 10 itself, perfectly isolated, associated with a first broken titanium plate 14 to which the corresponding anodic plate 4 will be attached. Likewise, the configuration can be double, so that inside the tubular plate 8, two broken titanium plates 14 30 will appear, one at each end, to which corresponding anodic plates 4 will be attached. Likewise, according to the execution of figure 15, the current limiter itself, forming of the adapter element 6, it can be embedded in a block 15 of epoxy resin interposed in the titanium plate 8, being divided into two parts and whose 35 titanium plate 8 is finished off in a broken way to be able to be fixed to the respective plateAnodic 4. As in the previous case, the adapter element may have a double configuration to be fixed to two anodic plates 4. The number of vertical distribution bars 3 and anodic plates 4 per anode 1 does not affect the object of the invention. , but an adequate value of these will allow us to adjust the 5 benefits and costs of the installation so that, a practical number of elements is: 3 vertical bars, 30 adapter elements per anode where each of them feeds 2 anodic plates, so both a total of 60 anodic plates per anode. In addition, the anodic plates will have an area of 250 to 1670 cm2. On the other hand, in a conventional anode the number of anodic plates 4 is one or two, so that if it is two it is one per face, as shown in Figure 1 of the designs. Although the object of the invention can be applied to this conventional model, its effectiveness increases if it has a greater number of anodic plates 4 per anode, on the other hand the difficulties of cost and installation will prohibit values that are too high, establishing thus a compromise between both. We consider that an area of anodic material will define an anodic plate different from another as long as the electrical resistance between both areas is high enough so that when a cathodic contact with one of them is established, the other can follow its electrolysis process, at least, in the order of 30% activity. Each adapter element 6 will comprise at least one current limiting assembly 7, which in the case of short circuit will cut the current or at least limit said current to acceptable values, considering the non-hazardous values for the integrity of the anode acceptable and not they represent a great loss of current, we recommend a value similar to the normal operating current or nominal current, however we could work with higher values without significantly affecting the performance up to a short circuit current that does not exceed about five times the value of the nominal operating current. On the other hand, a second objective of the invention is to try to control the emissions of "acid mist" produced in the anodic electrolysis, for which in the cells for electro obtaining metals, such as copper, for anodes that feed two plates anodic 4, as shown in figure 1, separated by 10 to 30 mm., by arranging the anodic plates 4 with a slight inclination, as seen in figures 17, 35, 20 and 21, it is allowed to control and channel the bubbles produced. being able to obtain the path followed, according to the arrows "A", as a result of the inclination of the platesanodic, which can be obtained in many different ways. In addition, by varying the magnitude of the inclination of the anodic plates and arranging them with an increasing degree of inclination from bottom to top, an arrangement is generated, as an inverted spike, obtaining a chimney effect that allows the dispersion and controlled emission of acid bubbles when confined and ascending as in a chimney between the two faces of anodic plates of an anode. The inclination of the anodic plates, as we have indicated, can be achieved in different ways, and thus, firstly, the adapter element 6 comprising a current limiting assembly 10 7, figure 5 of the designs, can be fixed to the vertical distribution bar 3 directly with the desired degree of inclination or the titanium plate 8 itself being fixed to the corresponding vertical distribution bar 3 according to the desired degree of inclination or that the titanium plate 8 itself, as shown in Figures 17 and 18, a twist is present and its ends are the ones that are inclined and that when fixing the corresponding current limiting assembly the anodic plate fixed thereto presents the desired inclination. This phenomenon that concentrates the flow of ascending bubbles inside the anode provides the following advantages: 20  reduction of the resistance of the electrolyte to the passage of the current between anode and cathode, since, the ascending bubbles between anode and cathode are insulating by which increase the effective resistance of the electrolyte;  improvement of the uniformity of copper in the cathode plate, it is well known that there is a higher current density and also a greater incidence of short circuits in the lower part of the anode, that is to say a slightly greater thickness of copper in the lower part. If we avoid the bubbles between cathode anode that are concentrated in the upper part, we will obtain a flatter copper plate with a smaller thickness difference between the upper and lower part of the copper plate. 30  reduce the probability that these bubbles reach the cathode and cause oxidation that negatively affects the performance of the cathodic metal deposition process and its quality, and;  As a large percentage of acid bubbles rise through the narrow inner zone of the two anodic faces, the installation of a collector just outside the chimney will allow a very effective collection of the “acid fog” and howAs a consequence, substantially avoid environmental pollution.
