Description

The innovation relates to a "filter press, consisting of a side-by-side arrangement of _s - stretched out. Filter plates _s where two adjacent _s with their edges adjoining filter plates" form a filter chamber and for the supply of the sludge to be filtered. are provided in the broad sides of the one of a FiIterplatten breakthroughs, "while sur discharge of FII Trats on the inside of the filter plates" are available by a ■ -Filtertuch abgeckte channels ". '

During the filtration process, step; In particular, towards the end of the filtration, there are multiple pressure differences between the individual filter chambers of the filter press on "The broads rarely, the one-of-one filter plates are consequently 'Druc-kuntei" - differentiated _s depending on the desired thin-walled design of these broadsides; -light. - can lead to deformations'. Such deformations of the filter plate width.

pages are, however, not only for mechanical reasons undesirable _s but make sure also in'Feuchtigkeitsunterschieden of the individual ''Filtesrfcamern;. arising

The innovation is therefore based on the "task" - a. Filter press of the aforementioned. Way of further developing =, that these. Defects of the known designs avoided will" ' ; .

This task is now solved according to the fact that on the broad side of the individual filter plates within the area enclosed by the pilter plate edge, stiffening attachments are provided, - 'the; an-. corresponding.'An-. ' Sentences of the adjacent filter plate "to the attachment _:. Come *.

Through this ".Ansätze look © ine mutual Abstütsung gives the broadside üer -einzelnen filter plates _s so that the deformations occurring in the known embodiments' with all its disadvantages avoided .-. Contact." _: -
