This invention relates to a filter cloth suspending apparatus in which a filter cake is produced by pressing sewage and waste water between filter cloths with filter plates, and the obtained cake is discharged. In the apparatus, an upper edge of the filter cloth (3) is supported on an upper supporting bar (13), on the other hand, a lower edge of the filter cloth is formed in a concave shape, and a suspending member (15) is connected to both corners (18, 20). Thus, the contact of the lower edge of the filter cloth with the upper supporting bar is prevented, and damage of the filter cloth is prevented. Further, sagging of the lower edge of the filter cloth is also prevented.
L'invention concerne un appareil destiné à la suspension du tissu filtrant d'un filtre-presse, dans lequel un gâteau de filtre se forme entre des parties de tissu filtrant, lorsque les eaux d'égout et les eaux usées sont soumises, entre lesdites parties de tissu filtrant, à une pression exercée par une plaque, et est ensuite évacué. Une partie terminale supérieure d'un tissu filtrant (12) est soutenue par une barre de support supérieure (13), la partie terminale inférieure dudit tissu comportant une échancrure et des éléments de suspension (15) étant reliés aux deux coins (18, 20) de cette partie terminale inférieure. Cela empêche la barre de support supérieure et la partie terminale inférieure du tissu filtrant d'entrer en contact et le tissu filtrant de se rompre. Cela empêche également un affaissement de la partie terminale inférieure du tissu filtrant.
