Abstract

La réalisation, objet de l'invention, permet quel que soit le degré d'ajustement de la housse ou quelle que soit la façon dont elle est montée, de venir se serrer sur le secteur dès qu'elle est en contact avec une source de chaleur de 80 degrés C de quelque nature qu'elle soit De plus, les fils qui composent les médias filtrants de ces housses ont des propriétés qui permettent une déformation élastique de cette dernière, ce qui permet qu'après le soufflage employé lors du débatissage, la housse qui a été momentanément gonflée reprend sa place initiale, annulant ainsi tout risque de plis, donc de détérioration. A titre indicatif non limitatif, dans le cas cité, le média filtrant qui peut être un tissu tissé ou un non tissé armuré, possède un retrait dans le sens largeur. Ce retrait est donné par l'emploi de fils ayant la propriété de se rétracter et de demeurer élastiques. L'invention peut être appliquée à tous les filtres à disques à secteur existant dans l'industrie, quel que soit le milieu basique ou acide du produit à filtrer, avec simplement quelques réserves si la solution à filtrer est très chargée en acide sulfurique ou nitrique. Dans ces deux cas, le problème est à considérer particulièrement.
