Patent ID: 8496839

Claim:
A method for filtering a suspension, comprising the step: filtering a suspension which is initially inducted through a filling shoe into a filter chamber on a cake side of a filter cloth, which then permeates the filter cloth to a filtrate side of the filter cloth, and flows from the filter chamber on the filtrate side in a filtered state as a filtrate, while a solid content of the suspension is deposited on the fitter cloth as a filter cake, wherein the filter chamber in a closed state of a filter device is configured between a filter plate and a counter plate, and the filling shoe is anchored in the filter plate, and clamps the filter cloth with the filter plate in a sealing manner in the closed state, wherein the filter device is subsequently opened, so that the filter plate and the counter plate have an offset and the fitter cake is removed; and wherein the filling shoe automatically lifts off from the filter plate and releases the clamping of the filter cloth when the filter device is opened.
