1) SPREADER CLAMP
In this version, a steel retaining bracket for the filter cloth is mounted on the chamber filter plate or membrane filter plate. In its normal state, the filter cloth is pressed against the respective filter plate by a spring. The corresponding „buckling“ of the retaining bracket is effected by the adhering filter cake or its weight when the individual chambers are opened. The buckling movement releases the filter cake from the filter cloth (automatic filter cake release aid). The reduced weight of the retaining bracket/filter cloth combination means that the tension spring can now return to its vertical basic position.
