Abstract

Keksinnön kohteena on menetelmä sekä laitteisto erityisesti painesuodattimen suodatinkammiossa (14) muodostuvan kiintoainekakun (23) kontrolloimiseksi. Olennaista keksinnössä on, että suodatuksen aikana muodostuvaa kiintoainekakkua kontrolloidaan kakkuun kohdistetun puristuspaineen avulla. FIG 1The invention relates to a method and apparatus for controlling the solids cake (23) formed in the filter chamber (14) of a pressure filter. The essential feature of the invention is that the solids cake formed during filtration is controlled by means of the compression pressure applied to the cake. FIG 1
