Con el fin de minimizar la tensión (diferencia de potencial) necesaria para hacer pasar una determinada cantidad de corriente entre los electrodos a través del medio que se somete al tratamiento de la electrocoagulación, dichos electrodos se deben colocar con una separación pequeña entre ellos, pero sin embargo, debido a la carga positiva de los electrodos ánodos, éstos atraen a las sustancias coloidales que hay en el medio de tratamiento, produciéndose unos depósitos sobre la superficie de dichos electrodos, que si no se retiran llegan a producir la pasivación de esos electrodos, de manera que se interrumpe el paso de la corriente electrolítica.In order to minimize tension (difference of potential) necessary to pass a certain amount of current between the electrodes through the medium that is submitted to electrocoagulation treatment, said electrodes are due place with a small separation between them, but nevertheless, Due to the positive charge of the anode electrodes, they attract colloidal substances in the treatment medium, producing deposits on the surface of said electrodes, which, if not removed, produce the passivation of  those electrodes, so that the passage of the electrolytic current

Para solucionar ese problema es necesario realizar una limpieza periódica de los electrodos, pero debido al tiempo que requiere el desmontaje de los electrodos para efectuar dicha limpieza y las dificultades que la misma plantea, lo que habitualmente se hace es apurar el funcionamiento hasta que la suciedad acumulada en los electrodos impide un rendimiento aceptable, desmontándose entonces los electrodos para su sustitución por otros nuevos, lo cual supone un mal aprovechamiento de los electrodos, ya que se desechan cuando aún contienen material utilizable.To solve that problem it is necessary Perform periodic cleaning of the electrodes, but due to the time required to disassemble the electrodes to perform said cleaning and the difficulties that it poses, which usually done is to rush the operation until the accumulated dirt on the electrodes prevents performance acceptable, then disassembling the electrodes for replacement by new ones, which is a bad use of the electrodes, as they are discarded when they still contain material usable.

Objeto de la invenciónObject of the invention

De acuerdo con la invención se propone un sistema que permite efectuar una limpieza permanente de los electrodos electrolíticos durante el propio proceso de la electrocoagulación, consiguiendo de este modo una mayor eficiencia y rendimiento del proceso, así como un mejor aprovechamiento de los electrodos, ya que permite la utilización de éstos hasta su total agotamiento.According to the invention, a system that allows permanent cleaning of the electrolyte electrodes during the process of the electrocoagulation, thus achieving greater efficiency and process performance, as well as a better use of electrodes, since it allows the use of these until its total exhaustion.

Este sistema de la invención consiste en disponer entre cada dos electrodos del conjunto electrocoagulador un rascador formado por una barra de material eléctricamente aislante, unida a un mecanismo de desplazamiento transversal en vaivén por entre los electrodos.This system of the invention consists of arrange between every two electrodes of the electrocoagulator assembly a scraper formed by a bar of material electrically insulator, attached to a transverse displacement mechanism in sway between the electrodes.

De este modo, en la propia disposición del montaje funcional de los electrodos, e incluso cuando éstos se hallan funcionando en el proceso de la electrocoagulación, se puede efectuar la limpieza de los mismos de forma automática, simplemente activando el accionamiento del movimiento de los rascadores del sistema de limpieza.Thus, in the disposition of the functional assembly of the electrodes, and even when they are they are working in the electrocoagulation process, you can clean them automatically, simply activating the movement drive of the scrapers of the cleaning system

En la forma de realización práctica, los distintos rascadores dispuestos entre los electrodos de un conjunto de aplicación se establecen unidos entre sí, con lo que mediante un solo mecanismo actuador se realiza el movimiento de todos los rascadores en la acción funcional de la limpieza de aplicación, por lo que el costo del sistema de limpieza y su consumo son muy reducidos.In the practical embodiment, the different scrapers arranged between the electrodes of a application set are established linked together, so through a single actuator mechanism the movement of all scrapers in the functional action of cleaning application, so the cost of the cleaning system and its Consumption are very small.

Por todo ello, dicho sistema objeto de la invención resulta de unas características ciertamente ventajosas, adquiriendo vida propia y carácter preferente para la función a la que se halla destinada su aplicación.Therefore, said system object of the invention results from certainly advantageous features, acquiring own life and preferential character for the function to the that your application is intended.

Descripción detallada de la invenciónDetailed description of the invention

El objeto de la invención se refiere a un sistema de limpieza de los electrodos que se utilizan en el tratamiento de electrocoagulación de los vertidos de las almazaras o productos semejantes, para realizar una limpieza automática de los electrodos (1) de aplicación, incluso durante el desarrollo del proceso de funcionamiento de los mismos.The object of the invention relates to a electrode cleaning system used in the electrocoagulation treatment of oil mill spills or similar products, to perform an automatic cleaning of the electrodes (1) of application, even during the development of the their operation process.

El sistema consiste en disponen entre cada dos electrodos (1) del conjunto de aplicación un rascador (2) formado por una barra de material eléctricamente aislante, estableciéndose los rascadores (2) así dispuestos en acoplamiento con un mecanismo (3) de desplazamiento en movimiento de vaivén transversal por entre los electrodos (1).The system consists of disposing between every two electrodes (1) of the application assembly a scraper (2) formed by a bar of electrically insulating material, settling the scrapers (2) thus arranged in coupling with a mechanism (3) displacement in transverse reciprocating movement by between the electrodes (1).

Los distintos rascadores (2) intercalados en un conjunto de electrodos (1), se disponen unidos entre sí, formando un conjunto solidario que permite ser actuado mediante un solo mecanismo (3) para el desplazamiento de todos los rascadores (2) por entre los electrodos (1).The different scrapers (2) interspersed in a set of electrodes (1), arranged together, forming a solidarity set that allows to be acted by a single mechanism (3) for the displacement of all scrapers (2) between the electrodes (1).

Dicho desplazamiento de los rascadores (2) entre los electrodos (1) puede ser en sentido vertical o en sentido horizontal, sin que ello altere el concepto del sistema, pudiendo utilizarse para el movimiento un mecanismo (3) de cualquier tipo (hidráulico, neumático, mecánico-eléctrico, etc.), sin que esto tenga tampoco relevancia en el concepto del sistema.Said displacement of the scrapers (2) between  the electrodes (1) can be vertical or in the direction horizontal, without altering the system concept, being able to a mechanism (3) of any type be used for movement (hydraulic, pneumatic, mechanical-electric, etc.), without this having relevance in the concept of system.
