Abstract

The rotary scraper of the invention is intended to remove the material which has adhered to the conveyor belt, said scraper being installed under the conveyor belt at the proximity of the motor drum. It is comprised of a plurality of blades (4) arranged in the longitudinal direction and conveniently in a helical arrangement thereby forming a cylindrical surface by being secured to a pair of extreme washers which are integral with a motor shaft. The cylindrical body is mounted transversally to the belt and bears by its shaft onto roller bearings (5). The rotation of the scraper is provided by the motor drum (9) of the conveyor belt (7) or by an independent motor. The sheets (4) or turns of the helical winding embodied by the active crests of the scrapers are oriented to the right and to the left at each of the middle points of the cylindrical body thereby eliminating axial forces to the scraper axis.he sheets (4) of the scraper can be recharged with hard metal or can be covered with screwed plates (15) which carry hard metal bars.

Description

RASCADOR ROTATIVO PARA BANDAS TRANSPORTADORAS OBJETO DE LA INVENCIÓN ROTARY SCRAPER FOR CONVEYOR BELTS OBJECT OF THE INVENTION

La presente invención, según lo expresa el enunciado de esta memoria descriptiva, consiste en un rascado rotativo para bandas transportadoras, el cual se instala generalmente en la cabeza de vertido de dichas bandas transportadoras, de forma que, aprovechando el giro del eje motriz en muchos casos, en otros el giro del eje del tambor de presión, y en otros mediante un accio- namiento propio mediante la correspondiente transmisión, se hace girar el rascador rotativo, consiguiendo una limpieza muy eficaz de la banda por la pare inferior al transporte, de tal manera que se evita el derramamiento de material adherido a la banda y que generalmente se va desprendiendo a lo largo de toda la parte inferior de la misma.The present invention, as expressed in the description of this specification, consists of a rotary scratch for conveyor belts, which is generally installed in the pouring head of said conveyor belts, so that, taking advantage of the rotation of the drive shaft in many In other cases, the rotation of the axis of the pressure drum, and in others by means of its own drive by means of the corresponding transmission, the rotary scraper is rotated, achieving a very efficient cleaning of the belt by the lower part of the transport, in such a way that the spillage of material adhered to the band is avoided and that it is generally detached along the entire lower part thereof.

Acorde con la invención se pretende hacer pasar por toda la superficie de la banda, unas láminas rascadoras capaces de retirar todo el material adherido a la misma y sin que éste material cólmate o embace el rascador rotativo, ya que de lo contrario perderla toda su eficacia.According to the invention, it is intended to pass through the entire surface of the belt, scraper blades capable of removing all the material adhered thereto and without this material being seated or embracing the rotary scraper, since otherwise it will lose all its effectiveness .

ANTECEDENTES DE LA INVENCIÓN Las explotaciones mineras, las centrales térmicas, las fábricas de cemento, las fábricas de productos cerámicos, las fábricas de alúmina, etc., mueven mediante bandas transportadoras, millones de toneladas al año de materiales de muy distintas características . La mayoría de estos materiales por su naturaleza, tienen propiedades adherentes tanto más cuanto más grado de humedad contienen, creando graves problemas en las bandas transportadoras . Los problemas son mayores cuando los materiales que se transportan contienen partículas abrasivas que pueden producir desgastes prematuros en los elementos rotativos de las bandas transportadoras, sobre todo, en los rodillos de apoyo inferiores.BACKGROUND OF THE INVENTION Mining farms, thermal power plants, cement factories, ceramic products factories, alumina factories, etc., move through conveyor belts, millions of tons per year of materials of very different characteristics. Most of these materials, by their nature, have more adherent properties the more they contain moisture, creating serious problems in the conveyor belts. The problems are greater when the materials being transported contain abrasive particles that can cause premature wear on the rotating elements of the conveyor belts, over all in the lower support rollers.

Las normas de seguridad e higiene en el trabajo, exigen que las instalaciones industriales han de mantenerse totalmente limpias. En procesos de fabricación continua es a veces peligroso limpiar debajo de una banda transportadora en marcha, con independencia del costo que conlleva.Occupational health and safety regulations require that industrial facilities must be kept completely clean. In continuous manufacturing processes it is sometimes dangerous to clean under a running conveyor belt, regardless of the cost involved.

También las normas de medio ambiente, reclaman un gran interés en mantener todo el entorno de las industrias exento de contaminación. Cuando se trata de canteras o minas a cielo abierto, no es fácil evitar derramamientos de materiales que pueden contaminar, bien al ser arrastrados por el viento cuando se secan, o cuando estos materiales son arrastrados por las lluvias, contami- nando ríos y embalses.Also the environmental norms, demand a great interest in keeping the whole environment of the industries free of contamination. When it comes to open-air quarries or mines, it is not easy to avoid spills of materials that can contaminate, either by being dragged by the wind when they dry, or when these materials are swept away by the rains, contaminating rivers and reservoirs.

Con los rascadores convencionales y los cepillos limpiadores para bandas transportadoras que existen en el mercado, se han conseguido resultados importantes, pero en la actualidad la gran capacidad de producción de las industrias y la variedad de materiales que se utilizan, demandan un sistema de limpieza de las bandas transportadoras, eficaz y con mantenimiento mínimo.With the conventional scrapers and cleaning brushes for conveyor belts that exist in the market, important results have been achieved, but today the large production capacity of the industries and the variety of materials used, demand a cleaning system of Conveyor belts, efficient and with minimal maintenance.

DESCRIPCIÓN DE LA INVENCIÓN En lineas generales y para solucionar los problemas anteriormente comentados y alcanzar a la vez los objetivos preconizados, el rascador rotativo para bandas transportadoras, que constituye el objeto de la invención, es capaz de limpiar perfectamente las bandas por su parte inferior o ramal de retorno, sin dañar las bandas y manteniendo toda la eficacia.DESCRIPTION OF THE INVENTION In general and in order to solve the aforementioned problems and at the same time achieve the recommended objectives, the rotary scraper for conveyor belts, which is the object of the invention, is capable of perfectly cleaning the belts by its lower part or return branch, without damaging the bands and maintaining all the efficiency.

Esté basado en un conjunto de espiras en movimiento rotativo que limpian toda la superficie de la banda por su parte inferior al transporte y que ha per a- necido en contacto con el material. De esta forma se pueden transportar todo tipo de materiales por muy húmedos y adherenteε que sean, sin el desagradable problema de la contaminación y con la ventaja de la reducción de costos, en mantenimiento y limpieza. - El cuerpo del rascador está constituido por una pluralidad de láminas dispuestas en sentido longitudinal y con distribución cilindrica, quedando tendidas y aseguradas a unas arandelas solidarias a un eje motriz, el cual puede tomar movimiento aprovechando el giro del tambor de la cinta transportadora, o con accionamiento propio mediante un motor eléctrico y la transmisión correspondiente.It is based on a set of turns in rotating movement that clean the entire surface of the band by its inferior part to the transport and that has appeared in contact with the material. This way you can transport all types of materials, however wet and adherent, without the unpleasant problem of contamination and with the advantage of cost reduction in maintenance and cleaning. - The body of the scraper is constituted by a plurality of sheets arranged in a longitudinal direction and with cylindrical distribution, being laid and secured to some washers in solidarity with a drive shaft, which can take movement taking advantage of the rotation of the drum of the conveyor belt, or with its own drive by means of an electric motor and the corresponding transmission.

El eje dispuesto transversalmente a la cinta, queda debidamente soportado en cojinetes, pudiendo girar a gran velocidad para cumplir eficazmente su misión, ya que los grandes espacios formados entre las láminas y el interior hueco del cilindro virtual formado con ellas, no hace posible que el material cólmate el rascador rotativo en detrimento de su eficacia. Ventajosamente, las láminas están orientadas helicoidalmente para hacer más efectiva la limpieza, como sucede con el ataque de piñones helicoidales o coronas sin fin. En una forma de realización preferente, la mitad del rascador cilindrico tiene orientadas sus láminas en sentido contrario al de la otra mitad para compensar o equilibrar los esfuerzos axiales que pudieran producirse, además de que con esta disposición se evita que la banda transportadora se desplace o incline hacia un lado, como lo haría si fuera único el sentido de las espiras . Las láminas del cilindro rascador son recargadas en su diámetro exterior con carburo de tusteno con una altura de preferentemente 3 a 4 mm. antes de ser mecanizadas. De esta forma se consigue una dureza de 700 a 730 HV, resistente al desgaste con materiales normales o ligeramente abrasivos. Cuando se trata de bandas que transportan materiales muy abrasivos, las espiras o láminas del rascador se recubren con placas atornilladas a las que se han soldado barras de metal duro (bidia), consiguiendo asi una mayor resistencia al desgaste.The axis arranged transversely to the belt, is properly supported on bearings, being able to rotate at high speed to effectively fulfill its mission, since the large spaces formed between the sheets and the hollow interior of the virtual cylinder formed with them, does not make it possible for the material cover the rotary scraper to the detriment of its effectiveness. Advantageously, the sheets are helically oriented to make cleaning more effective, as is the case with the attack of helical pinions or endless crowns. In a preferred embodiment, half of the cylindrical scraper has its blades oriented in the opposite direction to that of the other half to compensate or balance the axial stresses that may occur, in addition to this arrangement preventing the conveyor belt from moving or Tilt to one side, as you would if the direction of the turns were unique. The blades of the scraper cylinder are recharged in their outer diameter with tustene carbide with a height of preferably 3 to 4 mm. before being mechanized. In this way a hardness of 700 to 730 HV is achieved, resistant to wear with normal or slightly abrasive materials. When it comes to belts that carry very abrasive materials, the spiers or sheets of the scraper are coated with bolted plates to which hard metal bars (bidia) have been welded, thus achieving greater wear resistance.

Para evitar pegaduras en el propio rascador, las arandelas, las láminas helicoidales y el eje motriz se construyen en material inoxidable. En una variante el eje puede ser forrado con chapa inoxidable entre las arande- las, consiguiendo igual efecto.To avoid sticking on the scraper itself, the washers, the helical blades and the drive shaft are constructed of stainless material. In a variant the shaft can be lined with stainless steel between the washers, achieving the same effect.

Para complementar la descripción que seguidamente se va a realizar y con objeto de ayudar a una mejor comprensión de las características de la invención, se acompaña a la presente memoria descriptiva, un juego de planos en cuyas figuras, con carácter ilustrativo y no limitativo se representan los detalles significativos de la invención.To complement the description that is going to be carried out below and in order to help a better understanding of the characteristics of the invention, a descriptive set is attached to the present specification, whose figures, with an illustrative and non-limiting nature, are represented the significant details of the invention.

DESCRIPCIÓN DE LA FORMA DE REALIZACIÓN PREFERIDADESCRIPTION OF THE PREFERRED EMBODIMENT

A la vista de las comentadas figuras y de acuerdo con la numeración adoptada en ellas, podemos observar como el rascador rotativo para bandas transportadoras, que la invención propone, está constituido en este ejemplo de realización, por el eje motriz 1 al que están solidarizadas las arandelas extremas 2 e intermedia 3 para anclaje de las láminas o espiras 4 dispuestas helicoidal- mente determinando un cuerpo cilindrico rotativo y con doble sentido de orientación de sus espiras, por los motivos anteriormente señalados.In view of the aforementioned figures and in accordance with the numbering adopted in them, we can observe how the rotary scraper for conveyor belts, which the invention proposes, is constituted in this example of embodiment, by the driving axis 1 to which the end washers 2 and intermediate 3 for anchoring the sheets or turns 4 helically arranged determining a rotating cylindrical body and with a double direction of orientation of its turns, for the reasons indicated above.

La referencia 5 designa los soportes de rodamiento como medios de apoyo del eje motriz 1. El giro del eje 1 se consigue a través de la polea 6 calada en el extremo del mismo, mediante la oportuna transmisión por correa.Reference 5 designates the bearing supports as support means of the drive shaft 1. The rotation of the shaft 1 is achieved through the sheave 6 pulled at the end thereof, by means of the appropriate belt drive.

En la figura 2 se muestra un ejemplo de montaje del rascador rotativo acoplado bajo la cinta transportadora 7, aplicado contra el ramal tensor o inferior 8 de la misma, en proximidad al tambor motriz 9. El rascador rotativo está referenciado en general con el número 10 y en este ejemplo de realización mostrado en la figura 2, toma movimiento de la polea 11 calada en el eje del tambor motriz 9, por intermedio de correas 12. La referencia 13 designa un tambor tensor del ramas inferior de la banda transportador 8 de la instalación.Figure 2 shows an example of mounting the rotary scraper coupled under the conveyor belt 7, applied against the tensioning or lower branch 8 thereof, in proximity to the driving drum 9. The rotary scraper is generally referenced with the number 10 and in this exemplary embodiment shown in Figure 2, it takes movement of the sheave 11 engaged in the axis of the driving drum 9, by means of belts 12. Reference 13 designates a tensioning drum of the lower branches of the conveyor belt 8 of the installation.

Haciendo ahora especial referencia a las figuras 4 y 5 donde se muestra las secciones transversa- les de láminas o espiras 4 del rascador rotativo 10, según dos ejemplos de realización dependiendo de la aplicación del dispositivo y de la naturaleza de los materiales transportados. Como dijimos anteriormente, cuando se trabaja con materiales normales o ligeramente abrasivos, basta con recargar las espiras 4 en su diámetro exterior con carburo de tusteño 14, resistente al desgaste. Cuando los materiales transportados por las bandas son muy abrasivos, las láminas o espiras 4 se cubren en la superficie de ataque con las placas 15 atornilladas y que incluyen las barras 16 de metal duro (widia) consiguiendo asi mayor resistencia al desgaste.With special reference now to figures 4 and 5 where the cross sections of sheets or turns 4 of the rotary scraper 10 are shown, according to two embodiments depending on the application of the device and the nature of the materials transported. As we said before, when working with normal or slightly abrasive materials, simply recharge the turns 4 in its outer diameter with tusteño carbide 14, wear resistant. When the materials transported by the bands are very abrasive, the sheets or turns 4 are covered on the attack surface with the plates 15 screwed and which include the bars 16 of hard metal (widia) thus achieving greater wear resistance.

Con esta disposición, el rascador rotativo para bandas transportadoras, es muy eficaz, de muy bajo costo en mantenimiento y muy bajo o casi nulo el riesgo de causar daños en las propias bandas transportadoras. Las espiras tanto a derechas como a izquierdas, rozan la superficie de la banda 8 con una ligera presión suficiente para limpiar la banda sin dañarla.With this arrangement, the rotary scraper for conveyor belts, is very effective, very low maintenance cost and very low or almost no risk of causing damage to the conveyor belts themselves. The turns, both right and left, touch the surface of the band 8 with a slight enough pressure to clean the band without damaging it.

Los materiales adheridos a las bandas transportadoras se desprenden con toda facilidad al deslizarse toda la superficie de la banda por las crestas de las espiras del rascador rotativo. The materials adhered to the conveyor belts detach easily when the entire surface of the belt slides along the ridges of the turns of the rotary scraper.
