Abstract

346,191. Filter-presses. SOC. OF CHEMICAL INDUSTRY IN BASLE, Basle, Switzerland. May 1, 1930, No. 13469. Convention date, May 1, 1929. [Class 46.] Hollow heating elements b are suspended in the frames a which separate the plates p of a filter. press. The elements may, as shown in Fig. 2, be supported by pins x and pipes y. They may be of iron, coated with a resistant metal such as lead, nickel, silver or copper, and their surface may be increased by projections or corrugations. They may be heated electrically or by steam, hot water or hot oil circulated through the pipes y. In operation the cakes separated from the liquid under treatment are first subjected to a blast of air for the removal of residual liquid. The elements b are then heated and the cakes dried, vapour being driven off through the openings e and passage k, through which the liquid to be filtered is supplied. The drying operation may be aided by hot gas or vapour introduced through ducts c, which serve for the discharge of filtrate.
