Abstract

VÁLVULA DE MANGUEIRA PARA ALIMENTAR MATERIAL GRANULADO FINO A invenção se refere a uma válvula de tubo para a saída de material finamente granulado, preferivelmente lama de cal seca que mantém um nível de conteúdo de matéria seca de 65-90%, onde a válvula de tubo compreende um tubo interno elástico disposto dentro de uma câmara de pressão que rodeia o tubo interno elástico. De acordo com a invenção, uma válvula de tubo 14 é usada como meios de saída do processo pressurizado. A válvula de tubo tem um comprimento mínimo que é duas vezes o diâmetro do tubo, e uma coluna de lama de cal pode ser segurada dentro disso como uma trava de pressão, e a coluna de lama de cal pode ser descendida através da válvula de tubo por controle da diferença em pressão entre a superfície interna e a superfície externa do tubo tal que o diâmetro do tubo se expande essencialmente uniformemente ao longo do seu comprimento por 5-10% ou por pelo menos 4-6 mm.
