A la vista de las comentadas figuras y de acuerdo con la numeración adoptada podemos observar como partiendo de un molino 1 para la molturación de arcillas y similares de tipo convencional, mediante unos elementos accesorios se permite proceder al cambio de la parrilla 2 de tamizado de una forma sencilla, rápida, cómoda y económica, presentando la parrilla 2 de tamizado una forma arqueada según un ángulo, aproximado, de 180º.In view of the commented figures and of according to the numbering adopted we can see how starting of a mill 1 for grinding clays and the like conventional, by means of accessory elements it is allowed proceed to change the sieve grill 2 in a way simple, fast, comfortable and economical, presenting grill 2 of sieving an arched shape according to an approximate angle of 180º.
Asimismo, el molino 1 de tipo convencional para la molturación de arcillas y similares presenta la correspondiente boca 10 de alimentación del producto a molturar y una tapa 11 de cierre.Also, mill 1 of conventional type for the grinding of clays and the like presents the corresponding feed port 10 of the product to be ground and a cover 11 of closing.
Así, para proceder al cambio de la parrilla 2 de tamizado, con la tapa 11 abierta, en primer lugar se procederá a la liberación de las porciones de carcasa 3 semicirculares de cierre lateral relativas a ambos lados de la parrilla 2 de tamizado, mediante la liberación de unos tornillos 18 de fijación al chasis 5 fijo del molino 1 respecto de su tramo arqueado.Thus, to proceed to change grill 2 of sieving, with the lid 11 open, first proceed to the release of the semicircular closing housing portions 3 lateral relative to both sides of the sieve grill 2, by releasing screws 18 securing the chassis 5 Fixed mill 1 with respect to its arcuate section.
Asimismo, en una realización preferente de la invención, a la cara externa de los platos 6 extremos porta martillos se fijan respectivos bulones 7, en sentido axial, con objeto de que topen sobre el lado recto de las porciones de carcasa 3 semicirculares de cierre lateral relativa a ambos lados de la parrilla 2 de tamizado, tal como se observa en la figura 1 de los diseños.Also, in a preferred embodiment of the invention, to the outer face of the 6 end plates porta hammers are fixed respective bolts 7, axially, with object of bumping on the straight side of the housing portions 3 semicircular lateral closure relative to both sides of the sieve grill 2, as shown in figure 1 of the designs.
Por otra parte, las porciones de carcasa 3 semicirculares libres al haber sido liberadas del chasis 5 del molino 1 se fijarán a correspondientes soportes 8 curvos dispuestos sobre el eje rotor 9 provisto de los platos 6 porta martillos, de forma que en su fijación, respecto del lado recto, son elevadas ligeramente al presentar en relación a la zona del eje rotor una pequeña holgura 4 de, aproximadamente, 5 mm., quedando ancladas las porciones de carcasa 3 semicirculares al eje rotor 9.Moreover, the housing portions 3 semicircular free having been released from chassis 5 of the mill 1 will be attached to corresponding 8 curved brackets arranged on the rotor shaft 9 provided with the hammer holder plates 6, of so that in their fixation, with respect to the straight side, they are elevated slightly when presenting in relation to the rotor shaft area a small clearance 4 of approximately 5 mm, with the shell portions 3 semicircular to the rotor shaft 9.
Asimismo, el lado recto de las porciones de carcasa 3 semicirculares presentan una prolongación 12 extrema de contacto sobre la parrilla 2 de tamizado, para lo cual en los extremos de dicha parrilla 2 se ha practicado un pequeño rebaje 13 de encaje, tal como se puede apreciar en la figura 11.Also, the straight side of the portions of semicircular housing 3 have an extreme extension 12 of contact on sieve grill 2, for which in the ends of said grill 2 a small recess 13 has been made of lace, as can be seen in figure 11.
Una vez realizadas las operaciones descritas se procederá a girar el eje rotor 9, para lo cual, según una ejecución practica de la invención, el eje rotor 9 presenta un volante 14 al cual se une, en posición excéntrica, el émbolo de un cilindro 15.Once the operations described have been completed, will proceed to rotate the rotor shaft 9, for which, according to one execution practice of the invention, the rotor shaft 9 has a flywheel 14 to the which joins, in eccentric position, the piston of a cylinder fifteen.
Así, el volante 14 presenta varios puntos 16 de anclaje del cilindro 15, así como varios puntos 17 de fijación estática del volante.Thus, the steering wheel 14 has several points 16 of cylinder anchor 15, as well as several fixing points 17 Steering wheel static.
De esta forma, para el giro del volante 14 se fijará el émbolo del cilindro 15 en un punto 16 (figura 1) y se accionará el cilindro girando el volante 14, aproximadamente, 90º, procediendo a anclar el volante 14 por uno de los puntos 17, definidos por un orificio pasante, mediante el simple paso de un bulón y apoyo en la propia estructura del molino.In this way, for turning the steering wheel 14, fix the piston of the cylinder 15 at a point 16 (figure 1) and will drive the cylinder by turning the flywheel 14, approximately, 90º, proceeding to anchor the steering wheel 14 by one of the points 17, defined by a through hole, by simply passing a bolt and support in the mill structure itself.
A continuación, se liberará el émbolo del cilindro 15 y se fijará en un nuevo punto 16, más próximo a él, liberando el volante 14 y procediendo a un nuevo giro de, aproximadamente, 90º, quedando la parrilla totalmente accesible en el exterior.Then the piston will be released from the cylinder 15 and will be fixed at a new point 16, closer to it, releasing steering wheel 14 and proceeding to a new turn of, approximately 90º, leaving the grill fully accessible in the outside.
Esto es así dado que, con el giro del volante 14 se provoca el giro de las porciones de carcasa 3 semicirculares al estar ancladas al eje rotor 9 por los soportes 8, en lo que colaboran los bulones 7, a la vez que las prolongaciones extremas de las porciones de carcasa 3 semicirculares arrastran a la parrilla 2 de tamizado provocando su giro (figuras 5 y 6) hasta quedar en el exterior libre para su liberación y cambio.This is so because, with the steering wheel turn 14 rotation of the semicircular housing portions 3 is caused to the be anchored to the rotor shaft 9 by the supports 8, in which the bolts 7 collaborate, while the extreme extensions of the semicircular housing portions 3 drag to the sieve grill 2 causing its rotation (figures 5 and 6) until be abroad free for release and change.
La zona arqueada de parrilla presenta una pestaña que se encastra en un cuerpo 19 de caucho o similar, tal como se puede observar en la figura 12 de los diseños.The arched grill area has a tab that is embedded in a rubber body 19 or the like, such as can be seen in figure 12 of the designs.
Así, a continuación se procederá de forma inversa para colocar la nueva parrilla de tamizado en su posición de trabajo.Thus, then proceed in a manner Reverse to place the new sieve grill in position of work.
Lógicamente, el giro de la parrilla 2 de tamizado en lugar de realizarlo por medio del cilindro, tal como se ha descrito, se podrá llevar a cabo por cualquier otro medio equivalente, como puede ser un moto-reductor o de forma manual.Logically, the turn of the grid 2 of sieving instead of performing it by means of the cylinder, as described, may be carried out by any other means equivalent, such as a motor reducer or manual form
