Filter press

The furnace refers to eina filter press consisting of a _s Anaahl from vertical in about position; juxtaposed right polygonal filter plate "* whose sum channeled flow of the liquid ■ versehe" = ne, by filtertüoher covered broad sides of a recess in ways ;: with the corresponding "recess of the adjacent filter plate a" for receiving the serving be filtered sludge Kam " ». Mer forms in which a filter cake remains after the liquid is pressed out.

In chemical process engineering "often sludgy substances have to be filtered. This is the case, for example, in cement production," when the raw material is processed wet.

The articulated arms 21 and 22 are also, in this embodiment, attached to the pin plates via articulated axles 20 and connected to one another at their upper end via joint sleeves 23 Rather, up to rods 9 and 10, in this exemplary embodiment are provided directly on articulated arms 21 and 22 .

The illustration according to FIG. 4, which shows the filter plates 1a and Td in the extended state and the filter plates Ib and 1c in the extended state, shows the movement that the rods 9 and 10 execute when the filter press is opened. " They move away from each other and in this case erswisgen thereby a movement of the upper edge of the Pilier; tliehar I ₃ through which the filter cake is abgelöat 15 of the filtertUcttsrE 7 ".

The G-elenlcanne 21 and 2S can also be formed in the embodiment according to Pig.
in this way one can create a elastic suspension of the
Rods 9 and 10 and thus the same mode of operation
achieve «2 miä- ψ when executing according to the Pig,
