Abstract

The invention relates to a cooling cover to be secured externally to the rotating drum of cement mixer trucks, which cools the freshly mixed cement contained therein. The device is formed by a cover which is made to the dimensions of the rotating drums of cement mixers, adapted to the shape of same and fitted using a system of ties. The cover must be absorbent in order to allow a large quantity of water to accumulate, which, owing to the wind, evaporates as the truck moves and the drum rotates. The water may be distributed directly onto the cover. During the water evaporation process, the cover is cooled, thereby generating a thermal delta and a heat transfer from the cement contained inside the rotating drum to the cover, which reduces the temperature of the freshly mixed cement.

CUBIERTA REFRIGERANTE PARA SER FIJADA EXTERNAMENTE AL TAMBOR ROTATORIO DE CAMIONES HORMIGONEROS QUE ACTÚA REFRIGERANDO EL HORMIGÓN FRESCO CONTENDDO.COOLING COVER TO BE FIXED EXTERNALLY TO THE ROTARY DRUM OF CONCRETE TRUCKS THAT ACTING COOLING THE COOL CONCRETE CONTAINED.
Existen distintos métodos utilizados ampliamente para producir un descenso en la temperatura del hormigón fresco. There are different methods widely used to produce a decrease in the temperature of fresh concrete.
Entre estos métodos están los relacionados con la refrigeración de la materia prima: Among these methods are those related to the cooling of the raw material:
Refrigeración de los áridos: Sombreado, riego, uso de ventiladores, etc  Aggregate cooling: shading, irrigation, fan use, etc.
Refrigeración del agua: Adición de escamas de hielo.  Water cooling: Adding ice flakes.
Refrigeración del cemento: Aplicación de aire helado, ventilación.  Cement cooling: Application of frozen air, ventilation.
También están los métodos relacionados con la refrigeración del hormigón fresco: There are also methods related to cooling fresh concrete:
Incorporación de hielo a la mezcla (en reemplazo de ciertos volúmenes de agua) Inyección de nitrógeno líquido u otros gases helados dentro de la mezcla.  Incorporation of ice into the mixture (replacing certain volumes of water) Injection of liquid nitrogen or other frozen gases into the mixture.
Duchas de agua sobre los camiones hormigoneras.  Water showers on concrete mixer trucks.
Las técnicas actuales proponen la combinación de una o mas de las técnicas descritas anteriormente, con distintos grados de sofísticación, de acuerdo al nivel de disminución de temperatura deseado y a la temperatura ambiental en el momento de la confección del hormigón, la cual depende de la hora del día y de la estación del año. Por otra parte, las técnicas actuales tratan de controlar la temperatura antes de que el camión sea cargado y/o salga de la planta o previo al momento de vaciado del camión. Current techniques propose the combination of one or more of the techniques described above, with varying degrees of sophistication, according to the level of decrease in temperature desired and the ambient temperature at the time of concrete fabrication, which depends on the time of the day and the season of the year. On the other hand, current techniques try to control the temperature before the truck is loaded and / or leaves the plant or prior to the time of emptying the truck.
La presente invención, al contrario, no utiliza ninguna de las técnicas mencionadas anteriormente, consiste en un aditamento al tambor rotatorio de los camiones hormigoneras, que se adosa externamente y cuyas características permiten realizar la función de enfriamiento de la mezcla de hormigón fresco durante el transporte del mismo.  The present invention, on the contrary, does not use any of the techniques mentioned above, consists of an attachment to the rotary drum of concrete mixer trucks, which is externally attached and whose characteristics allow to perform the cooling function of the fresh concrete mixture during transport of the same.
Básicamente este dispositivo está constituido por una cubierta confeccionada a la medida del tambor rotatorio del camión hormigonera y que se adapta a la geometría del mismo, mediante un sistema de fijación, de modo que quede ajustada y permite su retiro y reutilización.  Basically this device is constituted by a cover made to measure of the rotary drum of the concrete mixer truck and that adapts to its geometry, by means of a fixing system, so that it is adjusted and allows its removal and reuse.
La cubierta d ebe tener características absorbentes, con la finalidad de que permita acumular un gran volumen de agua, el cual debido al viento se irá evaporando en la medida que el tambor gira y que el camión avanza. El agua se puede aportar por riego directo sobre la cubierta. Durante el proceso de evaporación del agua, la cubierta se irá enfriando, generándose de este modo un delta térmico y una transferencia de calor desde el hormigón contenido dentro del tambor rotatorio hacia la cubierta, lo cual hará disminuir la temperatura del hormigón fresco. The cover must have absorbent characteristics, in order to allow a large volume of water to accumulate, which due to the wind will evaporate as the drum rotates and the truck advances. Water can be provided by direct irrigation on the roof. During the process of evaporation of the water, the roof will be cooled, thus generating a thermal delta and a heat transfer from the concrete contained inside the rotating drum to the roof, which will lower the temperature of the fresh concrete.
Para aumentar la capacidad de absorción de la cubierta, ésta puede estar provista de un sistema de acumulación de agua, que puede ser cualquier material absorbente adherido interna, externamente o en el núcleo de la cubierta y que puede tener cualquier disposición geométrica, pudiendo comprometer toda la extensión o sólo parte de ella. A medida que el agua de la cubierta se va secando, el agua retenida en el sistema de acumulación se distribuirá a la cubierta p ara aumentar su capacidad evaporativa y extender el tiempo de autonomía de la cubierta. In order to increase the absorption capacity of the cover, this can be provided with a water accumulation system, which can be any absorbent material adhered internally, externally or in the core of the cover and which can have any geometric arrangement, being able to compromise all the extension or only part of it. TO As the cover water dries up, the water retained in the accumulation system will be distributed to the cover to increase its evaporative capacity and extend the time of autonomy of the cover.
El dispositivo de la invención no requiere de la introducción de nuevos comandos o elementos de sujeción en los camiones hormigoneros tradicionales, aún cuando es posible soldar ganchos a la cubierta del tambor rotatorio, para permitir un ajuste mas rápido. The device of the invention does not require the introduction of new commands or fasteners in traditional concrete trucks, even when it is possible to weld hooks to the rotary drum cover, to allow a faster adjustment.
El dispositivo de la invención es ecológico. No emite polución ni contaminación por agente alguno. The device of the invention is ecological. It does not emit pollution or contamination by any agent.
Es sustentable. Funciona utilizando energías aportadas por la naturaleza (viento) y las propiedades naturales del agua.  It is sustainable. It works using energies contributed by nature (wind) and the natural properties of water.
No requiere energía externa, pues basta con los movimientos propios del camión (rotación y traslación) para que el sistema funcione.  It does not require external energy, because the truck's own movements (rotation and translation) are enough for the system to work.
No involucra el uso de tecnologías caras o instalaciones especiales.  It does not involve the use of expensive technologies or special facilities.
No atenta contra el medio ambiente. It does not threaten the environment.
No requiere el uso de energía y despliegue técnico para generar y almacenar hielo y/o nitrógeno.  It does not require the use of energy and technical deployment to generate and store ice and / or nitrogen.
