Description

Campo técnico Technical field

La presente invención hace referencia a un molino particularmente para aplastar cuerpos hechos de materiales metálicos reciclables y similares. The present invention refers to a mill particularly for crushing bodies made of recyclable metal materials and the like.

Estado de la técnica State of the art

Los molinos para aplastar cuerpos metálicos, tales como desechos de vehículos a motor y similares, son actualmente conocidos que tienen una carcasa con forma de caja provista internamente de una cubeta para acomodar un rotor de tipo rodillo equipado con martillos trituradores, véase por ejemplo EP1332796. Mills for crushing metal bodies, such as motor vehicle debris and the like, are currently known to have a box-shaped housing internally provided with a bucket to accommodate a roller-type rotor equipped with crushing hammers, see for example EP1332796.

La parte superior de la carcasa está provista de cubiertas que son adecuadas para cubrir la cubeta dentro de la cual opera el rotor, para contener los fragmentos aplastados dentro del molino. The upper part of the housing is provided with covers that are suitable to cover the bucket within which the rotor operates, to contain the crushed fragments within the mill.

Al menos una de las cubiertas está provista de un compartimento de entrada para los cuerpos a ser aplastados. At least one of the covers is provided with an entry compartment for the bodies to be crushed.

La cubeta tiene, debajo del rotor, una rejilla para descargar el material aplastado, al que el rotor está adyacente para formar, entre ellos, un hueco a través del cual los cuerpos a ser aplastados son arrastrados para aplastarlos mediante acciones de golpear y triturar de los martillos. The bucket has, under the rotor, a grid to unload the crushed material, to which the rotor is adjacent to form, between them, a gap through which the bodies to be crushed are dragged to crush them by hitting and crushing actions. The hammers

En general, en la base del molino hay ranuras para descargar el material aplastado expulsado desde la cubeta a través de la rejilla y hay un compartimento para expulsar del molino las partes que no pueden ser aplastadas. In general, at the base of the mill there are slots to discharge the crushed material ejected from the bucket through the rack and there is a compartment to eject the parts that cannot be crushed from the mill.

Molinos de este tipo tienen varios dispositivos de ajuste, principalmente para la cubeta, que deben ser preestablecidos como una función de los cuerpos a ser aplastados. Mills of this type have several adjustment devices, mainly for the bucket, which must be preset as a function of the bodies to be crushed.

La preparación de estos dispositivos actualmente requiere: The preparation of these devices currently requires:

-abrir el molino, -open the mill,

-levantar el rotor, que a menudo permanece enganchado y soportado por una de las cubiertas, en una posición que se encuentra encima de la cubeta, - lift the rotor, which often remains engaged and supported by one of the covers, in a position that is located above the bucket,

-equipar el molino con los componentes apropiados por parte de personal que sustancialmente entra en el molino, trabajando dentro de la cubeta. - Equip the mill with the appropriate components by personnel who substantially enter the mill, working inside the bucket.

Del mismo modo, la sustitución del recubrimiento interno del molino, pretendido para proteger su estructura internamente de los cuerpos a ser aplastados, tal como el recubrimiento de la rejilla o el recubrimiento lateral de la cubeta, requiere el mismo procedimiento. In the same way, the replacement of the internal lining of the mill, intended to protect its structure internally from the bodies to be crushed, such as the grid covering or the side covering of the bucket, requires the same procedure.

Por lo tanto, este tipo de molino tiene el inconveniente de requerir a los operarios asignados a montarlos y mantenerlos que trabajen directamente en el molino abierto, que es un espacio confinado a menudo hecho peligroso mediante sustancias tóxicas y/o inflamables y posiblemente volátiles que han percolado allí a partir de los cuerpos introducidos para aplastarlos, tales como bidones de pinturas o aceites, motores, etc. Therefore, this type of mill has the disadvantage of requiring the operators assigned to assemble them and keep them working directly in the open mill, which is a confined space often made dangerous by toxic and / or flammable and possibly volatile substances that have percolated there from the bodies introduced to crush them, such as paint drums or oils, engines, etc.

Limpiar la cubeta que acomoda el rotor es igualmente incómodo, ya que también requiere la acción de un operario que sustancialmente trabaja dentro del molino. Cleaning the bucket that accommodates the rotor is equally uncomfortable, as it also requires the action of an operator who substantially works inside the mill.

Además, la sustitución de los dispositivos o el mantenimiento de la cubeta de molinos actualmente conocidos es oneroso no sólo debido a las razones de seguridad descritas sino porque se mantiene el molino inmóvil, y por lo tanto improductivo, durante todo el tiempo requerido para el mantenimiento y/o montaje. In addition, the replacement of the devices or the maintenance of the bucket of currently known mills is burdensome not only because of the safety reasons described but also because the mill is still, and therefore unproductive, for the entire time required for maintenance. and / or assembly.

En el campo de los molinos para aplastar materiales metálicos reciclables se siente la necesidad por lo tanto de tener molinos disponibles que tengan una estructura que permita montarlos de forma más sencilla y rápida que los molinos actualmente conocidos. In the field of mills to crush recyclable metal materials, the need is therefore felt to have mills available that have a structure that allows them to be assembled more easily and quickly than the mills currently known.
