A placa filtrante de espuma cer\u00e2mica foi projetada como um item descart\u00e1vel; portanto, \u00e9 necess\u00e1rio garantir uma maneira eficaz de vedar a placa filtrante em seu suporte, de modo a facilitar a montagem, a desmontagem e a limpeza. O pr\u00f3prio sistema de filtragem de metal fundido geralmente \u00e9 composto pela caixa de filtragem e pela placa de filtragem, entre outros componentes, e deve ser fabricado com material refrat\u00e1rio resistente ao metal fundido, semelhante ao material refrat\u00e1rio utilizado na estrutura padr\u00e3o do tanque. Utilize um dispositivo de veda\u00e7\u00e3o el\u00e1stico ou uma veda\u00e7\u00e3o do tipo junta para fixar a placa de filtragem de espuma cer\u00e2mica no lugar.<\/p>\n

O placa filtrante de espuma cer\u00e2mica<\/a> \u00e9 cercado por uma junta de veda\u00e7\u00e3o, que atua na superf\u00edcie de contato entre a placa filtrante e a caixa do filtro para impedir que o alum\u00ednio l\u00edquido vaze por essa superf\u00edcie.<\/p>\n

Nossa placa filtrante utiliza tr\u00eas tipos diferentes de junta de veda\u00e7\u00e3o: com borda de papel de fibra; com borda de algod\u00e3o de fibra; com borda de algod\u00e3o expandido.<\/p>\n

A veda\u00e7\u00e3o envolve a placa do filtro em sua parte inclinada. A junta de veda\u00e7\u00e3o garante que n\u00e3o haja vazamentos na instala\u00e7\u00e3o e proporciona um meio de separa\u00e7\u00e3o eficaz, o que \u00e9 essencial para facilitar a desmontagem.<\/p>\n

Al\u00e9m disso, como as juntas ou dispositivos de veda\u00e7\u00e3o impedem que o metal penetre na superf\u00edcie de veda\u00e7\u00e3o da unidade de fixa\u00e7\u00e3o, seu uso simplifica bastante a limpeza e prolonga efetivamente a vida \u00fatil da unidade, eliminando o problema da corros\u00e3o do metal.<\/p>\n

Al\u00e9m disso, devido \u00e0 sua elasticidade, a junta pode proporcionar atrito suficiente para manter o corpo do filtro no lugar no suporte ou na c\u00e2mara do filtro, sem a necessidade de recorrer a outros tipos de dispositivos de press\u00e3o. O dispositivo de veda\u00e7\u00e3o el\u00e1stico deve ser adequado para o metal fundido espec\u00edfico, n\u00e3o deve ser molhado pelo metal, deve ser resistente \u00e0 corros\u00e3o qu\u00edmica e deve ter resist\u00eancia ao fogo suficiente para suportar temperaturas operacionais mais elevadas.<\/p>\n

\"Veda\u00e7\u00e3o<\/p>\n

A unidade de filtro de espuma cer\u00e2mica pode ser vedada nas bordas e\/ou ao redor de sua grande superf\u00edcie por meio de juntas. A unidade de filtro de placa \u00e9 vedada, de prefer\u00eancia, ao longo da superf\u00edcie perif\u00e9rica externa inclinada da placa de filtro por meio de uma veda\u00e7\u00e3o do tipo borda, proporcionando assim uma veda\u00e7\u00e3o confi\u00e1vel e, juntamente com a junta, oferece a vantagem mec\u00e2nica de manter o filtro no lugar.<\/p>\n

Se o simples encaixe por press\u00e3o n\u00e3o for suficiente para fixar o filtro no lugar, \u00e9 natural recorrer a diversos equipamentos mec\u00e2nicos, como cunhas e pesos de compacta\u00e7\u00e3o. O \u00e2ngulo de chanfro da placa do filtro, correspondente ao \u00e2ngulo de chanfro da c\u00e2mara do filtro, tende a formar uma veda\u00e7\u00e3o confi\u00e1vel e a resistir \u00e0 flutuabilidade que atua sobre ele, fixando o filtro na posi\u00e7\u00e3o correta.<\/p>","protected":false},"excerpt":{"rendered":"
