Description
Dispositivo de preparación de una mezcla para la elaboración de hormigón, mortero, enlucido o análogo.Device for preparing a mixture for Concrete, mortar, plastering or similar processing.
La presente invención se refiere a un dispositivo de preparación de una mezcla para la elaboración de hormigón, mortero, enlucido o análogo, en particular para máquinas de proyectar.The present invention relates to a device of preparing a mixture for the production of concrete, mortar, plaster or the like, in particular for machines to project.
Un dispositivo conocido, al cual se refiere la invención, comprende una cuba de malaxado que corona una tolva de recepción que permite almacenar momentáneamente la mezcla preparada para el empleo, antes de su utilización. La mezcla, formada en la cuba de malaxado es vertida en la tolva, cuando ha alcanzado la consistencia y la homogeneidad deseadas. Una bomba especial, por ejemplo, de un tipo conocido bajo la denominación "bomba Moineau" está conectada a la parte inferior de la tolva para permitir la extracción de la mezcla, su transporte a un conducto y eventualmente su proyección. El conjunto puede estar montado sobre un chasis rodante que permite remolcar el dispositivo hasta el lugar de utilización.A known device, to which the invention, comprises a malaxado tank that crowns a hopper of reception that allows the prepared mixture to be stored momentarily for employment, before use. The mixture, formed in the Malaxado tank is poured into the hopper, when it has reached the consistency and homogeneity desired. A special bomb, for example, of a type known under the name "bomb Moineau "is connected to the bottom of the hopper to allow the extraction of the mixture, its transport to a conduit and Eventually your projection. The assembly can be mounted on a rolling chassis that allows towing the device to the place of use.
Los dispositivos conocidos más simples comprenden una cuba de malaxado provista de una abertura de carga superior. La cuba corona completamente la abertura horizontal de la tolva. La cuba puede comprender una salida baja mandada por una trampilla o estar montada de forma pivotante alrededor de un eje horizontal para que la mezcla sea vertida en la tolva, por basculación de la cuba. Estos dos sistemas presentan el inconveniente de que la abertura de carga de la cuba de malaxado está situada a un nivel bastante elevado, del orden de 1,20 m o más. La explotación es por tanto penosa para el operador encargado de alimentar la cuba de malaxado puesto que los materiales constitutivos de la mezcla deben ser elevados hasta el nivel de dicha abertura de carga.The simplest known devices comprise a bowl of malaxado provided with a top loading opening. The Cuba completely crowns the horizontal opening of the hopper. The Cuba can comprise a low outlet sent by a trapdoor or be pivotally mounted around a horizontal axis to that the mixture is poured into the hopper, by tilting the tank. These two systems have the disadvantage that the opening of Malaxado tank load is located at a fairly level elevated, of the order of 1.20 m or more. The exploitation is therefore painful for the operator in charge of feeding the tank of malaxado since the constituent materials of the mixture must be raised to the level of said loading opening.
Otra solución conocida recurre a una cuba de malaxado unida a un sistema de elevación accionado por medio de un gato hidráulico, gracias al cual la cuba de malaxado en su conjunto puede ser bajada hasta el suelo, al lado de la tolva de la carga. Cuando la mezcla está preparada, la cuba es elevada e invertida mecánicamente para transferir la mezcla a dicha tolva. Este sistema es de utilización menos penosa pero la instalación es costosa. La invención propone una solución razonable a todos estos problemas.Another known solution uses a tank of malaxado attached to a lifting system operated by means of a hydraulic jack, thanks to which the malaxado tank as a whole It can be lowered to the ground, next to the load hopper. When the mixture is prepared, the bowl is raised and inverted mechanically to transfer the mixture to said hopper. This system It is less painful to use but the installation is expensive. The invention proposes a reasonable solution to all these problems.
Más particularmente, la invención se refiere por tanto a un dispositivo de preparación de una mezcla, para la elaboración de hormigón, mortero, enlucido o análogo, del tipo que comprende una cuba de malaxado que corona una tolva de recepción que presenta una abertura por la cual dicha mezcla, formada en dicha cuba de malaxado, es vertida conteniendo dicha cuba de malaxado unos medios de removido aptos para poner en movimiento la mezcla contenida en ésta, caracterizado porque el fondo de dicha cuba de malaxado está situado a una altura inferior a aquélla en la cual se encuentra la abertura de dicha tolva, porque dicha cuba de malaxado presenta una salida lateral practicada encima de dicha abertura, obturada por una trampilla y porque el emplazamiento de dicha trampilla se elige para que la mezcla contenida en la parte inferior de dicha cuba de malaxado sea propulsada hacia dicha salida lateral por dichos medios de removido.More particularly, the invention relates to both to a device for preparing a mixture, for concrete, mortar, plastering or similar processing, of the type it comprises a malaxado tank that crowns a reception hopper that has an opening through which said mixture formed in said tank of malaxado, is poured containing said tank of malaxado Removal means suitable for moving the mixture contained therein, characterized in that the bottom of said tank of malaxado is located at a height lower than that at which find the opening of said hopper, because said bowl of malaxado it has a lateral outlet made above said opening, blocked by a trapdoor and because the location of said trapdoor is chosen so that the mixture contained in the bottom of said malaxado tank being propelled towards said lateral outlet by said removal means.
Preferentemente, la cuba de malaxado está instalada en una escotadura de la pared de dicha tolva. La misma puede estar fijada a la tolva, por ejemplo soldada a lo largo de dicha escotadura de manera que la mezcla no pueda escaparse de la tolva desbordando por dicha escotadura.Preferably, the malaxado tank is installed in a recess in the wall of said hopper. The same it can be fixed to the hopper, for example welded along said recess so that the mixture cannot escape from the hopper overflowing by said recess.
Los medios de removido pueden comprender clásicamente un sistema de palas rotativas de eje horizontal, arrastrada en rotación, por ejemplo por un motor hidráulico acoplado a este eje. Para una buena realización de la invención, dicho eje está preferentemente situado a un nivel superior a aquél en el que se encuentra la parte más baja de dicha salida lateral. Así, las palas de dichos medios de removido girando en un sentido adecuado, ejercen un empuje ascendente sobre la mezcla, según un cierto trayecto, definido en el interior de la cuba de malaxado y es suficiente prever el emplazamiento de dicha salida lateral frente a este trayecto ascendente creado por los medios de removido para que la mezcla, situada también a un nivel inferior de dicha salida lateral, sea evacuada por ésta y caiga en la tolva.The removal means may comprise classically a system of rotary blades of horizontal axis, dragged in rotation, for example by a hydraulic motor coupled to this axis. For a good embodiment of the invention, said axis it is preferably located at a level higher than that in which is the lowest part of said lateral exit. So, the shovels of said removal means rotating in a suitable direction, exert an upward thrust on the mixture, according to a certain path, defined inside the malaxado tank and is sufficient to provide for the location of said lateral exit in front of this ascending path created by the removal means so that the mixture, also located at a lower level of said outlet lateral, be evacuated by it and fall into the hopper.
Una vez en la tolva, la mezcla es extraída por la bomba, a medida de las necesidades. El nivel de mezcla utilizable, en la tolva, varía en consecuencia. En la mayor parte de los casos, la apertura de la trampilla se realiza manualmente bajo control del operador. Se puede imaginar sin embargo que la trampilla esté provista de medios de mando de apertura automática y que éstos sean mandados por los medios de detección de un nivel bajo predeterminado de producto, en dicha tolva.Once in the hopper, the mixture is extracted by pump, tailored to the needs. The mix level usable, in the hopper, it varies accordingly. In most cases, the trapdoor is opened manually under the control of the operator. You can imagine however that the trapdoor is provided with automatic opening control means and that these are sent by the detection means of a predetermined low level of product, in said hopper.
La invención se comprenderá mejor a la luz de la descripción que sigue, dada únicamente a título de ejemplo y con referencia al plano anexo, en el cual:The invention will be better understood in light of the description that follows, given by way of example only and with reference to the annexed plan, in which:
- la figura única es una vista esquemática en alzado del dispositivo de acuerdo con la invención.- the unique figure is a schematic view in elevation of the device according to the invention.
Haciendo referencia al plano, se ha representado un dispositivo de preparación 11 de una mezcla, para la elaboración de una masa de hormigón, mortero, enlucido o análogo. Este dispositivo se compone esencialmente de una cuba de malaxado 12 que corona una tolva de recepción 13 avanzando en resalte por encima de dicha tolva 13 La tolva presenta una abertura superior 14, horizontal, por la cual la mezcla formada en la cuba de malaxado es vertida cuando ha alcanzado la composición y la consistencia deseadas. La cuba de malaxado 12 presenta a su vez una abertura 16, en su parte superior, por la cual un operador vierte los ingredientes sólidos de la mezcla (cemento o cal, arena, grava, etc.). El fondo de la cuba de malaxado es redondeado, como se ha representado. Además, de forma clásica, la cuba de malaxado contiene unos medios de removido 17 aptos para poner en movimiento la mezcla contenida en ésta y crear una dispersión homogénea de los componentes. Estos medios de removido comprenden un sistema de palas rotativas 18, de eje horizontal 19 arrastrado en rotación por un motor hidráulico 20 exterior a la cuba. La cuba de malaxado es fija con respecto a la tolva. Una bomba 21, por ejemplo del tipo llamado "bomba Moineau" está conectada a la parte inferior de la tolva para extracción de la mezcla.Referring to the plan, it has been represented a preparation device 11 of a mixture, for processing of a concrete, mortar, plastered or similar mass. This device consists essentially of a malaxado cuba 12 which crown a receiving hopper 13 advancing in projection above said hopper 13 The hopper has an upper opening 14, horizontal, whereby the mixture formed in the malaxado tank is poured when it has reached composition and consistency desired. The malaxado tank 12 also has an opening 16, at the top, by which an operator pours the solid ingredients of the mixture (cement or lime, sand, gravel, etc.). The bottom of the malaxado tank is rounded, as it has been represented. In addition, in a classic way, the malaxado tank contains stirring means 17 suitable for moving the mixture contained in it and create a homogeneous dispersion of components. These removal means comprise a paddle system. rotary 18, horizontal axis 19 dragged in rotation by a hydraulic motor 20 outside the tank. The malaxado tank is fixed with respect to the hopper. A pump 21, for example of the type called "Moineau pump" is connected to the bottom of the hopper for extraction of the mixture.
Como se ha representado, el fondo de la cuba de malaxado está a una altura H_{1} inferior a la, H_{2}, en la que se encuentra la abertura horizontal 14 de la tolva. Además, dicha cuba de malaxado presenta una salida lateral 24 practicada en la parte de la cuba que avanza en resalte por encima de la abertura de la tolva. Esta salida lateral, que corona la abertura de la tolva, está obturada por una trampilla 25 articulada en 26 por su borde superior. Cuando la trampilla está cerrada, la mezcla no puede ser vertida en la tolva. Es importante observar que un emplazamiento de la trampilla se elige para que la mezcla contenida en la parte inferior de la cuba de malaxado (por debajo del borde inferior de la salida lateral 24) sea propulsada hacia dicha salida lateral 24 por dichos medios de removido.As depicted, the bottom of the Cuba de malaxado is at a height H_ {less} than the one, H_ {2}, in the that the horizontal opening 14 of the hopper is located. Further, said malaxado tank has a lateral outlet 24 made in the part of the tank that advances in projection above the opening of the hopper. This side exit, which crowns the opening of the hopper, is sealed by a trapdoor 25 articulated in 26 by its top edge When the trapdoor is closed, the mixture cannot be poured into the hopper. It is important to note that a site of the trapdoor is chosen so that the mixture contained in the part bottom of the malaxado tank (below the lower edge of the lateral outlet 24) is propelled towards said lateral outlet 24 by said removal means.
Para ello, el eje de rotación 19 del sistema de palas rotativas está situado a un nivel superior a la parte más baja de dicha salida lateral 24.To do this, the axis of rotation 19 of the system rotating blades is located at a level higher than the most low of said lateral outlet 24.
Como se ve en el plano, en el ejemplo descrito, la cuba de malaxado 12 está instalada en una escotadura 28 de la pared de la tolva 13. La cuba de malaxado está fijada a esta tolva preferentemente por ensamblado estanco, por ejemplo por soldadura o adición de una junta. De esta manera, la mezcla no corre el riesgo de escaparse de la tolva fluyendo por la parte baja de dicha escotadura.As seen in the plan, in the example described, the malaxado tank 12 is installed in a recess 28 of the wall of the hopper 13. The malaxado tank is fixed to this hopper preferably by tight assembly, for example by welding or adding a board. In this way, the mixture is not at risk to escape from the hopper flowing down the bottom of said recess
En un modo de realización simple, la trampilla 25 que obtura la salida lateral 24, está simplemente provista de un sistema enclavamiento de accionamiento manual. En el ejemplo representado, sin embargo, el dispositivo comprende unos medios de mando de apertura automática 30 de la trampilla, por ejemplo los medios de mando hidráulico por gato. Estos medios de mando de apertura automática pueden ser mandados a distancia. Ventajosamente, pueden estar asociados a unos medios de detección 32 de un nivel bajo predeterminado de mezcla, en dicha tolva. Estos medios de detección están acoplados (unión 36) a los medios de mando de apertura automática de la trampilla. De esta manera, la mezcla es automáticamente transferida en cantidad suficiente a la tolva 13 para que ésta no esté nunca completamente vacía y que la bomba sea siempre apta para funcionar.In a simple embodiment, the trapdoor 25 which closes the side outlet 24, is simply provided with a manual drive interlocking system. In the example represented, however, the device comprises means of automatic opening control 30 of the trapdoor, for example hydraulic control means by jack. These command means of Automatic opening can be sent remotely. Advantageously, they may be associated with detection means 32 of a level under predetermined mixing, in said hopper. These means of detection are coupled (junction 36) to the control means of automatic opening of the trapdoor. In this way, the mix is automatically transferred in sufficient quantity to hopper 13 so that it is never completely empty and that the pump is Always fit to work.
Gracias a esta disposición, el nivel de la
abertura de carga 16 de la cuba de malaxado es llevado a una altura
H razonable que limita la fatiga del operario encargado de
introducir los ingredientes en dicha cuba. Por otra parte, la
estructura del dispositivo es muy simple y poco costosa. Como se ha
indicado anteriormente, el dispositivo puede estar montado sobre un
carro que permite su remolcado de un lugar de
explotación a
otro.Thanks to this arrangement, the level of the loading opening 16 of the malaxado tank is brought to a reasonable height H that limits the fatigue of the operator in charge of introducing the ingredients into said tank. On the other hand, the structure of the device is very simple and inexpensive. As indicated above, the device can be mounted on a car that allows it to be towed from a place of
exploitation to another.
El dispositivo descrito comprende otras particularidades ventajosas. Así, la abertura 14 de la tolva 13 está recubierta por una cubierta de protección 38 necesaria para evitar que el operador pueda acceder a los medios de extracción, peligrosos. Está articulado por una charnela 39 a un elemento de la estructura fija. Este último forma aquí un conducto de ventilación 40 que se extiende entre una abertura 43 practicada en la parte superior de la cuba de malaxado 12 y el espacio dejado entre la tolva 13 y la cubierta 38. Una salida de aire 42 es definida en la cubierta a nivel de la abertura 14 de la tolva y en un emplazamiento alejado de la abertura 16 de la cuba de malaxado. Esta abertura 16 es de forma y dimensiones que corresponden sensiblemente a las de un saco de producto que contiene ingredientes secos necesarios para la preparación de la mezcla elegida (hormigón, mortero, enlucidos... ). El producto así propuesto está generalmente preparado para el empleo y sólo necesita ser mezclado con una cierta cantidad de agua.The described device comprises other advantageous features. Thus, the opening 14 of the hopper 13 is covered by a protective cover 38 necessary for prevent the operator from accessing the extraction means, dangerous. It is articulated by a hinge 39 to an element of the fixed structure The latter here forms a ventilation duct 40 extending between an opening 43 made in the part upper of the malaxado tank 12 and the space left between the hopper 13 and cover 38. An air outlet 42 is defined in the cover at the level of the opening 14 of the hopper and in a location away from the opening 16 of the malaxado tank. This opening 16 is of shape and dimensions that correspond substantially to those of a sack of product that contains dry ingredients necessary for the preparation of the chosen mixture (concrete, mortar, plasters ...). The product thus proposed is generally prepared for employment and just needs to be mixed With a certain amount of water.
Dichos productos preparados para el empleo están generalmente acondicionados en sacos de 30 kg. La abertura 16 está provista de una rejilla 44 sobre la cual el operador coloca el saco. La rejilla es en sí un elemento de seguridad que aísla al operador de los medios de removido. La misma está coronada, en su centro, por una especie de cortador 45 con amplios dientes destinado a reventar el saco cuando el operador lo coloca sobre la rejilla. Siendo las dimensiones de la abertura 16 (y de la rejilla 44) sensiblemente iguales a la sección del saco una vez elevado y después de haber sido cortado, la misma es por tanto completamente recubierta por el saco. Cuando el contenido de este último cae en la cuba de malaxado, el volumen de aire desplazado correspondiente, cargado de partículas finas que provienen del producto, fluye por el conducto de ventilación 40 hacia la tolva para salir de nuevo por la salida 42 en un punto alejado del operador. Mientras tanto, una gran parte de las partículas finas arrastradas por el aire ha caído de nuevo en la tolva. El volumen de aire también puede ser aspirado en la prolongación del conducto de ventilación 40 y eventualmente filtrado por unos medios conocidos y no descritos y ser evacuado lejos del operador.These products ready for use are generally conditioned in bags of 30 kg. The opening 16 is provided with a grid 44 on which the operator places the bag. The grid itself is a safety element that insulates the operator of the removal media. It is crowned, in its center, by a kind of cutter 45 with wide teeth intended to burst the bag when the operator places it on the rack. Being the dimensions of the opening 16 (and the grid 44) substantially equal to the bag section once raised and after been cut, it is therefore completely covered by the coat. When the content of the latter falls into the vat of malaxado, the corresponding displaced air volume, loaded with fine particles that come from the product, flows through the duct vent 40 to the hopper to exit again through the outlet 42 at a point away from the operator. Meanwhile, a large part of the airborne fine particles has fallen again in the hopper The volume of air can also be sucked into the prolongation of ventilation duct 40 and possibly filtered by known and undescribed means and be evacuated away from operator.
