Abstract
Equipo de regulación del nivel de fluido en depósitos. Equipo de regulación del nivel de fluidos en un depósito, que permite una rápida y fácil instalación así como un mínimo mantenimiento, ya que consta de una serie de sondas capacitivas instaladas en el exterior del depósito que contiene el fluido cuyo nivel se pretende regular, estando asociadas dichas sondas con unos sensores que envían la señal recibida hacia unos medios de control que deciden en función de la señal recibida enviar una señal de activación o no a unos medios de llenado, p.e. una electroválvula. De esta manera las sondas del equipo no están sometidas a un constante desgaste y averías derivadas del hecho de estar inmersas en un fluido, que en ocasiones puede ser ácido o corrosivo, no influyendo la tipología del producto en la precisión del equipo.Equipment for regulating fluid level in tanks. Fluid level regulation equipment in a tank, which allows a quick and easy installation as well as a minimum maintenance, since it consists of a series of capacitive probes installed outside the tank containing the fluid whose level is intended to be regulated, being said probes associated with sensors that send the received signal to control means that decide depending on the received signal to send an activation signal or not to filling means, eg a solenoid valve In this way, the probes of the equipment are not subject to constant wear and tear due to the fact of being immersed in a fluid, which can sometimes be acidic or corrosive, without influencing the product typology in the precision of the equipment.
Description
Equipo de regulación del nivel de fluido en depósitos.Fluid level regulation equipment in deposits
Es objeto de la presente invención un equipo regulador del nivel de fluidos en todo tipo de depósitos.The object of the present invention is a device regulator of fluid level in all types of tanks.
Caracteriza al presente equipo de regulación del nivel de fluidos una fácil y rápida instalación, así como un estabilidad en su funcionamiento sin sufrir deterioro alguno ya que no hay elemento activo alguno dentro de los fluidos cuyo nivel se pretende regular.Characterize this regulation equipment of the fluid level easy and quick installation, as well as a stability in its operation without suffering any deterioration since there is no active element within the fluids whose level is pretend to regulate
Caracteriza igualmente a la presente invención, el hecho de que las sondas de nivel empleadas no están sumergidas en fluido, por lo que no quedan sometidas al desgaste y constantes averías, siendo sondas de tipo capacitivo.It also characterizes the present invention, the fact that the level probes used are not submerged in fluid, so they are not subject to wear and constants breakdowns, being capacitive type probes.
Por lo tanto, la presente invención, se circunscribe dentro del ámbito de los equipos y medios empleados para la regulación del nivel de fluidos de cualquier tipo de depósitos.Therefore, the present invention will be circumscribes within the scope of the equipment and means used for the regulation of the level of fluids of any type of deposits
Hasta el momento, los equipos empleados para la regulación del nivel de un fluido en un depósito están basados en el empleo de una serie de sondas. Estas sondas deben estar sumergidas en el fluido cuyo nivel dentro del depósito se pretende regular, por lo que están sometidas a la acción de dicho fluido. En general, si bien hay fluidos inertes, no exime a las sondas de posibles averías y constante mantenimiento, con la dificultad que implica por el hecho de estar sumergidas. El problema derivado de la inmersión de las sondas dentro del fluido se ve agravado de forma particular cuando los fluidos son corrosivos, clorados o ácidos, lo que ciertamente provoca un rápido deterioro de las sondas.So far, the equipment used for the regulation of the level of a fluid in a tank are based on the use of a series of probes. These probes must be submerged in the fluid whose level inside the tank is intended regulate, so they are subject to the action of said fluid. In In general, although there are inert fluids, it does not exempt the probes of possible breakdowns and constant maintenance, with the difficulty that implies by the fact of being submerged. The problem derived from immersion of the probes within the fluid is aggravated by particular way when fluids are corrosive, chlorinated or acids, which certainly causes rapid deterioration of probes
Por otro lado, debido al hecho de tener que disponer las sondas dentro del fluido, la posición en la que se colocan dentro del depósito es fundamental, pudiendo hacerse necesario en ocasiones, modificar la posición de las sondas, hecho que se dificulta por estar dentro del depósito.On the other hand, due to the fact of having to arrange the probes within the fluid, the position in which it placed inside the tank is essential, and can be done sometimes necessary, modify the position of the probes, done which is difficult because it is inside the tank.
Por lo tanto, es objetivo de la presente invención, desarrollar un equipo de regulación del nivel de agua en depósitos, que evite los inconvenientes derivados de la necesidad de tener que disponer las sondas de nivel dentro del depósito y por lo tanto en contacto con los fluidos, evitando así un rápido deterioro, facilitando un rápido montaje y mantenimiento y regulación.Therefore, it is the objective of the present invention, develop a water level regulation equipment in deposits, that avoid the inconveniences derived from the need to have to have the level probes within the deposit and therefore in contact with fluids, thus avoiding rapid deterioration, facilitating rapid assembly and maintenance and regulation.
El objeto de la invención es un equipo de regulación del nivel de fluidos en depósitos que permite una rápida instalación del mismo, así como un fácil mantenimiento. El equipo permite un seguimiento y control de los distintos niveles posibles en un depósito, ofreciendo como respuesta a las señales emitidas por los sensores, en función de su nivel, salidas a 220V, salidas NC, salidas sonoras o visuales, en función del modelo.The object of the invention is a team of regulation of the level of fluids in tanks that allows rapid installation thereof, as well as easy maintenance. The team allows monitoring and control of the different possible levels in a warehouse, offering in response to the signals emitted by sensors, depending on their level, outputs at 220V, outputs NC, sound or visual outputs, depending on the model.
Estas señales pueden estar asociadas al accionamiento de motores, electroválvulas, paros de emergencia, bombas de trasvase, alarmas acústicas y ópticas o cualquier complemento que se conectara a dicho equipo.These signals may be associated with motor drive, solenoid valves, emergency stoppages, transfer pumps, acoustic and optical alarms or any complement that will connect to said equipment.
Gracias a las características del equipo es posible una variación de cualquiera de los niveles, así como la graduación de su sensibilidad en pocos segundos.Thanks to the characteristics of the equipment it is possible a variation of any of the levels, as well as the Graduation of your sensitivity in a few seconds.
El equipo objeto de la invención está formado por un conjunto de sondas capacitivas, asociadas a unas fuentes de alimentación de dichas sondas capacitivas, de unos medios de control, que dependiendo de la señal recibida de los sensores, actúan sobre los equipos o complementos asociados al regulador.The equipment object of the invention is formed by a set of capacitive probes, associated with some sources of feeding of said capacitive probes, of means of control, which depending on the signal received from the sensors, act on the equipment or accessories associated with regulator.
Gracias a que las sondas son de naturaleza capacitiva, por lo tanto no están sumergidas en fluido alguno, y que no quedan sometidas al desgaste y las constantes averías de las sondas convencionales.Thanks to the fact that the probes are of nature capacitive, therefore they are not submerged in any fluid, and that are not subject to wear and constant breakdowns of conventional probes.
El equipo objeto de la invención puede estar
