Abstract

"FILTRO DE PRESSãO COM TAMPA ACIONADA PNEUMATICAMENTE", O qual compreende um cilindro de filtragem (2) que encerra uma amostra de polpa de minério, câmara esta que é submetida a pressão de ar comprimido, comprimindo a amostra, fazendo separar a parte sólida da líquida desta amostra de polpa através de elemento filtrante; para movimentação da tampa (1) utiliza-se o pistão pneumático (4) comandado por válvula (5) que opera em dois sentidos, fechando e abrindo a tampa (1)."PNEUMATICALLY DRIVEN LID PRESSURE FILTER", which comprises a filter cylinder (2) enclosing an ore pulp sample, which chamber is subjected to compressed air pressure, compressing the sample, separating the solid portion from the liquid of this pulp sample through a filter element; To move the cap (1), the two-way valve-operated pneumatic piston (4) operates by closing and opening the cap (1).
