La presente invención se refiere a un dispositivo que permite la limpieza enérgica del interior de las mezcladoras de hormigón, y muy especialmente del agitador que constituye el elemento amasador de la mezcla.The present invention relates to a device which allows vigorous cleaning of the interior of the mixers of concrete, and especially the agitator that constitutes the Kneading element of the mixture.
Se conocen dispositivos para la limpieza de mezcladoras de hormigón consistentes en un conjunto de canalizaciones fijas provistas de orificios de pulverización de un líquido limpiador que incide sobre los elementos de la mezcladora más propensos a ensuciarse. Una tal solución presenta el inconveniente de que el líquido pulverizado se proyecta siempre sobre los mismos puntos, por lo que la limpieza no es completa, incluso aunque durante la misma se ponga en movimiento el agitador, necesitándose siempre varias boquillas, 3 ó 4 mínimas, y subiendo el número de boquillas si se quiere aumentar la superficie a limpiar, con el consiguiente costo de implantación y mantenimiento' de varias boquillas y los distribuidores de funcionamiento de estas.Devices are known for cleaning concrete mixers consisting of a set of fixed pipes provided with spray holes of a cleaning liquid that affects the elements of the mixer more likely to get dirty. One such solution presents the drawback that the sprayed liquid is always projected on the same points, so the cleaning is not complete, even if the agitator is set in motion during it, always needing several nozzles, 3 or 4 minimum, and going up the number of nozzles if you want to increase the surface to clean, with the consequent cost of implementation and maintenance of several nozzles and distributors of operation of these.
Es un objetivo de la presente invención el disponer de un dispositivo para la limpieza de mezcladoras de hormigón que, incorporado a las mismas de forma permanente, permita una proyección del líquido limpiador tal que se alcancen todos los puntos del interior de la mezcladora con una elevada energía y con una sola boquilla.It is an objective of the present invention the have a device for cleaning mixers concrete that, permanently incorporated into them, allows a projection of the cleaning liquid such that all points inside the mixer with high energy and with One nozzle
Para alcanzar el objetivo propuesto se ha concebido un dispositivo que puede ser incorporado a la tapa que cierra superiormente la cubeta que constituye el recipiente exterior de la mezcladora, y que consiste, básicamente, en un eje principal hueco, giratorio gracias a un grupo motriz, que en su parte inferior se prolonga ortogonalmente en un brazo terminado en un portaboquilla en el que se dispone una boquilla provista de una pluralidad de orificios de pulverización, libremente giratoria respecto al portaboquilla.To achieve the proposed objective, conceived a device that can be incorporated into the lid that close the bucket that constitutes the container outside of the mixer, and that basically consists of an axis main hollow, rotating thanks to a drive group, which in its bottom extends orthogonally on an arm terminated in a nozzle holder in which a nozzle provided with a plurality of spray holes, freely rotating Regarding the nozzle holder.
El eje principal esta recorrido en su interior por un primer conducto, cuya parte superior se comunica con la alimentación exterior del líquido limpiador a través de un conector rotativo, mientras que de su parte inferior, ya dentro de la mezcladora, sale un tubo de alimentación de líquido limpiador que termina en una cámara móvil del portaboquillas. Los orificios de pulverización de la boquilla, a su vez, están conectados a un segundo conducto interior comunicado con la cámara móvil del portaboquillas, lo que permite la proyección, por los orificios de pulverización de la boquilla, del líquido limpiador introducido en el eje principal hueco a través del conector rotativo.The main axis is inside by a first conduit, whose upper part communicates with the external feeding of the cleaning liquid through a rotary connector, while from its bottom, already inside the mixer, a cleaning liquid feed tube comes out which ends in a mobile camera of the nozzle holder. Holes spray nozzle, in turn, are connected to a second inner duct communicated with the mobile camera of the nozzle holder, allowing projection, through the holes of spray of the nozzle, of the cleaning liquid introduced in the hollow main shaft through the rotary connector.
Como ya hemos explicado, el brazo giratorio en cuyo extremo se dispone el portaboquilla, recibe su movimiento de un grupo motriz y, a su vez, la boquilla está sometida a un movimiento de giro respecto a su eje longitudinal, impuesto por medios de movilización adecuados que actúan automáticamente haciendo uso del movimiento circular del propio brazo giratorio. Estos medios de movilización pueden consistir, ventajosamente, en una simple cadena que engrana con una rueda dentada fija que forma parte de la propia tapa de la mezcladora y con una rueda dentada móvil solidaria de la boquilla.As we have already explained, the swivel arm in whose end the nozzle holder is arranged, receives its movement from a drive group and, in turn, the nozzle is subjected to a rotation movement with respect to its longitudinal axis, imposed by adequate means of mobilization that act automatically making use of the circular movement of the rotating arm itself. These means of mobilization may advantageously consist of a simple chain that meshes with a fixed cogwheel that forms part of the mixer lid itself and with a cogwheel solidarity mobile nozzle.
