Description
RIVESTIMENTO ED INSERTO PROTETTIVO PER PARETI DI MULINI, COATING AND PROTECTIVE INSERT FOR WALLS OF MILLS,
MESCOLATRICI, TRAMOGGE ED ALTRE MACCHINE MIXERS, HOPPERS AND OTHER MACHINES
La presente invenzione riguarda un rivestimento protettivo per pareti di mulini, mescolatrici, tramogge ed altre macchine, in particolare un rivestimento protettivo che può essere applicato a queste pareti per proteggerle da materiale in movimento. La presente invenzione riguarda anche un inserto protettivo che può essere inserito a pressione in tale rivestimento protettivo. The present invention relates to a protective coating for walls of mills, mixers, hoppers and other machines, in particular a protective coating that can be applied to these walls to protect them from moving material. The present invention also relates to a protective insert that can be press-fitted into such a protective coating.
EP 1479442, EP 1810752 ed EP 1990086 descrivono rivestimenti protettivi comprendenti pannelli od altri elementi elastomerici aventi un’elevata resistenza all’usura. Per migliorare ulteriormente la resistenza, inserti rigidi possono essere inseriti nel materiale elastomerico prima della sua vulcanizzazione. Per evitare il distacco accidentale degli inserti rigidi dal pannello parzialmente usurato durante l’uso, gli inserti devono essere sgrassati con solventi e rivestiti di uno o più strati di primer per consentire la loro perfetta adesione al pannello durante la vulcanizzazione. Tali trattamenti chimici però aumentano i costi ed i tempi di produzione, nonché sono ecologicamente svantaggiosi. EP 1479442, EP 1810752 and EP 1990086 describe protective coatings comprising panels or other elastomeric elements having a high resistance to wear. To further improve strength, rigid inserts can be inserted into the elastomeric material prior to its vulcanization. To avoid accidental detachment of the rigid inserts from the partially worn panel during use, the inserts must be degreased with solvents and coated with one or more layers of primer to allow their perfect adhesion to the panel during vulcanization. However, these chemical treatments increase costs and production times, as well as are environmentally disadvantageous.
Scopo della presente invenzione è pertanto quello di fornire un rivestimento protettivo esente da tali inconvenienti. Detto scopo viene conseguito con un rivestimento ed un inserto le cui caratteristiche principali sono specificate rispettivamente nelle rivendicazioni 1 e 11, mentre altre caratteristiche sono specificate nelle restanti rivendicazioni. The object of the present invention is therefore to provide a protective coating free from such drawbacks. Said object is achieved with a coating and an insert whose main characteristics are specified in claims 1 and 11 respectively, while other characteristics are specified in the remaining claims.
Grazie agli incastri a pressione del pannello elastomerico e dell’inserto rigido, è possibile inserire a pressione uno o più inserti in particolari sedi ricavate nel pannello, in modo da ottenere un accoppiamento resistente tra pannello ed inserti senza trattamenti chimici. Thanks to the pressure joints of the elastomeric panel and the rigid insert, it is possible to insert by pressure one or more inserts in particular seats obtained in the panel, in order to obtain a resistant coupling between panel and inserts without chemical treatments.
Grazie alla particolare forma ed alla particolare disposizione degli incastri, l’accoppiamento tra pannello ed inserti è mantenuto anche quando la loro superficie protettiva è consumata dall’uso. Thanks to the particular shape and the particular arrangement of the joints, the coupling between panel and inserts is maintained even when their protective surface is worn by use.
Preferibilmente, il profilo esterno della sezione trasversale degli inserti è sostanzialmente costante, in modo che inserti di differenti dimensioni possono essere fabbricati tagliando con differenti lunghezze un unico pezzo avente lo stesso profilo esterno. Preferably, the external profile of the cross section of the inserts is substantially constant, so that inserts of different dimensions can be manufactured by cutting with different lengths a single piece having the same external profile.
Inoltre, gli inserti possono essere applicati ai rivestimenti anche dopo la vulcanizzazione del pannello, persino dopo l’installazione dei rivestimenti sulle pareti da proteggere, così da semplificare il loro montaggio, dato che i pannelli senza inserti sono più leggeri e quindi più facili da sollevare per la loro installazione. Furthermore, the inserts can be applied to the coatings even after the panel has been cured, even after the installation of the coatings on the walls to be protected, so as to simplify their assembly, since the panels without inserts are lighter and therefore easier to lift. for their installation.
Secondo un particolare aspetto dell’invenzione, l’effetto sinergico della combinazione dei materiali impiegati per il pannello e per gli inserti, nonché delle loro forme e disposizioni, consente di ottenere un rivestimento avente una resistenza all’usura molto maggiore della resistenza dei rivestimenti noti, anche quando sono provvisti di inserti rigidi. According to a particular aspect of the invention, the synergistic effect of the combination of the materials used for the panel and the inserts, as well as their shapes and arrangements, allows to obtain a coating having a resistance to wear much greater than the resistance of the known coatings. , even when they are equipped with rigid inserts.
Ulteriori vantaggi e caratteristiche del rivestimento protettivo e dell’inserto protettivo secondo la presente invenzione risulteranno evidenti agli esperti del ramo dalla seguente descrizione dettagliata e non limitativa di due sue forme realizzative con riferimento agli annessi disegni in cui: Further advantages and characteristics of the protective coating and of the protective insert according to the present invention will become evident to those skilled in the art from the following detailed and non-limiting description of two of its embodiments with reference to the attached drawings in which:

La superficie esterna del pannello 1, ovvero la superficie inferiore nelle figure, è preferibilmente provvista di almeno una scanalatura sagomata 2, ad esempio con una sezione trasversale avente un profilo esterno sostanzialmente a forma di fùngo, per accoppiare il pannello 1 con un corrispondente profilo sagomato fissato alla superficie della macchina da proteggere. Le superfici laterali del pannello 1 sono preferibilmente provviste di scanalature 3 e/o rilievi complementari 4 per accoppiare il pannello 1 con uno o più pannelli adiacenti. La superficie protettiva del pannello 1, ovvero la superficie superiore nelle figure, che è la superficie consumabile che entra in contatto col materiale da cui proteggere la macchina, può essere provvista di almeno una protuberanza 5, in particolare una gobba parzialmente cilindrica disposta lungo la scanalatura sagomata 2. With reference to Figures 1 and 2, it can be seen that the coating according to the first embodiment of the present invention comprises in a known way an elastomeric panel 1, in particular made of rubber with a hardness between 35 Shore A and 97 Shore A or of polyurethane with a hardness between 35 Shore A and 55 Shore D. The external surface of the panel 1, i.e. the lower surface in the figures, is preferably provided with at least one shaped groove 2, for example with a cross section having an external profile substantially shaped downward, to couple the panel 1 with a corresponding shaped profile fixed to the surface of the machine to be protected. The side surfaces of the panel 1 are preferably provided with grooves 3 and / or complementary reliefs 4 for coupling the panel 1 with one or more adjacent panels. The protective surface of the panel 1, i.e. the upper surface in the figures, which is the consumable surface that comes into contact with the material from which to protect the machine, can be provided with at least one protuberance 5, in particular a partially cylindrical hump arranged along the groove shaped 2.
Facendo riferimento alle figure 3 e 4, si vede che il pannello 1 è provvisto di una o più sedi 6, 7 (mostrate con linee tratteggiate in figura 3) che sono aperte almeno verso la superficie protettiva e sono sagomate internamente verso il fondo per formare almeno un incastro a pressione. In particolare, tale incastro a pressione comprende una o più costole flessibili 8, 9 che sporgono da superfici laterali delle sedi 6, 7 ed hanno uno o più bordi arrotondati. La base 10 delle sedi 6, 7 è rastremata verso il fondo. With reference to Figures 3 and 4, it can be seen that the panel 1 is provided with one or more seats 6, 7 (shown with dashed lines in Figure 3) which are open at least towards the protective surface and are internally shaped towards the bottom to form at least one press fit. In particular, this pressure joint comprises one or more flexible ribs 8, 9 which protrude from the lateral surfaces of the seats 6, 7 and have one or more rounded edges. The base 10 of the seats 6, 7 is tapered towards the bottom.
Nella presente forma realizzativa, una o più prime sedi 6 comprendono almeno due costole parallele 8, 9 che sporgono da superfici laterali opposte. Le prime sedi 6 presentano una forma sostanzialmente parallelepipeda e sono disposte in una porzione sostanzialmente parallelepipeda del pannello 1 lungo colonne parallele e/o righe sfalsate, in particolare con una disposizione a quinconce. Una o più seconde sedi 7 presentano una forma sostanzialmente ad arco e sono disposte nella protuberanza 5 del pannello 1. Le seconde sedi 7 comprendono almeno due coppie di costole flessibili 8, 9 disposte una parallela all’altra alle estremità dell’arco delle seconde sedi 7. Le seconde sedi 7 sono inoltre disposte parallelamente lungo la protuberanza 5, in modo che la scanalatura sagomata 2 è disposta nell’arco delle seconde sedi 7. In the present embodiment, one or more first seats 6 comprise at least two parallel ribs 8, 9 which project from opposite lateral surfaces. The first seats 6 have a substantially parallelepiped shape and are arranged in a substantially parallelepiped portion of the panel 1 along parallel columns and / or staggered rows, in particular with a quincunx arrangement. One or more second seats 7 have a substantially arched shape and are arranged in the protuberance 5 of the panel 1. The second seats 7 comprise at least two pairs of flexible ribs 8, 9 arranged one parallel to the other at the ends of the arch of the second seats 7. The second seats 7 are also arranged parallel along the protuberance 5, so that the shaped groove 2 is arranged in the arc of the second seats 7.
Uno o più inserti protettivi 11, 12 realizzati in un materiale rigido, in particolare un materiale ceramico sinterizzato con un contenuto di allumina uguale o maggiore all’80%, una densità uguale o maggiore a 3,1 g/cm<3>ed una durezza Rockwell 45N uguale o maggiore a 70, sono atti ad essere disposti rispettivamente nelle sedi 6, 7 del pannello 1 e presentano una forma complementare a queste sedi, ovvero sostanzialmente parallelepipeda o ad arco. A tale scopo, la base gli inserti protettivi 11, 12 è provvista di almeno un incastro a pressione atto ad essere inserito nell’incastro a pressione delle sedi 6, 7. L’incastro a pressione degli inserti protettivi 11, 12 comprende una o più scanalature 13, 14 che sono ricavate lungo superfici laterali degli inserti 11, 12 ed hanno uno o più bordi arrotondati, in modo da poter essere accoppiate facilmente con le costole flessibili 8, 9 delle sedi 6, 7 del pannello 1. La base 15 degli inserti 11, 12 è rastremata, in modo da piegare facilmente le costole flessibili 8, 9 per realizzare l’accoppiamento a pressione. La distanza tra le scanalature 13, 14 e la superficie protettiva degli inserti 11, 12 è sostanzialmente uguale alla distanza tra le costole flessibili 8, 9 e la superficie protettiva del pannello 1. One or more protective inserts 11, 12 made of a rigid material, in particular a sintered ceramic material with an alumina content equal to or greater than 80%, a density equal to or greater than 3.1 g / cm <3> and a Rockwell hardness 45N equal to or greater than 70, are adapted to be arranged respectively in the seats 6, 7 of the panel 1 and have a shape complementary to these seats, ie substantially parallelepiped or arched. For this purpose, the base and the protective inserts 11, 12 are provided with at least one pressure joint adapted to be inserted into the pressure joint of the seats 6, 7. The pressure joint of the protective inserts 11, 12 comprises one or more grooves 13, 14 which are formed along lateral surfaces of the inserts 11, 12 and have one or more rounded edges, so as to be easily coupled with the flexible ribs 8, 9 of the seats 6, 7 of the panel 1. The base 15 of the inserts 11, 12 is tapered, so as to easily bend the flexible ribs 8, 9 to achieve the press fit. The distance between the grooves 13, 14 and the protective surface of the inserts 11, 12 is substantially equal to the distance between the flexible ribs 8, 9 and the protective surface of the panel 1.
Nella presente forma realizzativa, primi inserti 11 presentano una forma sostanzialmente parallelepipeda e sono inseriti a pressione nelle prime sedi 6 del pannello 1 grazie ad almeno una coppia di scanalature parallele 13, 14 ricavate lungo superfici laterali opposte dei primi inserti 11. Secondi inserti 12 presentano una forma sostanzialmente ad arco e sono inseriti a pressione nelle seconde sedi 7 del pannello 1 grazie ad almeno due coppie di scanalature parallele 13, 14 ricavate alle estremità dell’arco dei secondi inserti 12. Il pannello 1 è preferibilmente vulcanizzato prima che gli inserti 11, 12 sono inseriti in esso. In the present embodiment, first inserts 11 have a substantially parallelepiped shape and are inserted under pressure in the first seats 6 of the panel 1 thanks to at least one pair of parallel grooves 13, 14 obtained along opposite lateral surfaces of the first inserts 11. Second inserts 12 have a substantially arched shape and are inserted under pressure into the second seats 7 of the panel 1 thanks to at least two pairs of parallel grooves 13, 14 obtained at the ends of the arch of the second inserts 12. The panel 1 is preferably vulcanized before the inserts 11 , 12 are inserted therein.
Facendo riferimento alle figure 5 e 6, si vede che il rivestimento secondo la seconda forma realizzativa dell’invenzione comprende un pannello elastomerico 16 realizzato nello stesso materiale del pannello 1 ma con una forma sostanzialmente a settore circolare od anulare, in particolare anulare. La superficie esterna del pannello 16 è preferibilmente provvista di una o più scanalature sagomate 17 (mostrate con linee tratteggiate in figura 5) che sono disposte lungo assi radiali, mentre le superfici laterali sono preferibilmente provviste di scanalature 18 e/o rilievi complementari 19. Referring to figures 5 and 6, it can be seen that the coating according to the second embodiment of the invention comprises an elastomeric panel 16 made of the same material as the panel 1 but with a substantially circular or annular sector shape, in particular annular. The external surface of the panel 16 is preferably provided with one or more shaped grooves 17 (shown with dashed lines in figure 5) which are arranged along radial axes, while the lateral surfaces are preferably provided with grooves 18 and / or complementary reliefs 19.
Il pannello 16 è provvisto di una o più sedi che sono aperte almeno verso la superficie protettiva e sono sagomate internamente per ottenere un incastro a pressione simile a quello delle sedi 6. Dette sedi, nonché le costole dei relativi incastri a pressione, sono disposte lungo assi radiali del pannello 16. Inserti protettivi 20 realizzati con lo stesso materiale e sagomati sostanzialmente con la stessa sezione trasversale degli inserti 11 sono inseriti a pressione nelle sedi del pannello 16. The panel 16 is provided with one or more seats which are open at least towards the protective surface and are internally shaped to obtain a pressure joint similar to that of the seats 6. Said seats, as well as the ribs of the relative pressure joints, are arranged along radial axes of the panel 16.
