  • Heating element for a filter press
    Patent number: 8022338
    Abstract: The invention relates to a heating element for a filter press, that can be supplied with a fluid heating medium and comprises at least one heating plate consisting of a heat-conducting material and extending essentially over a plane. Said heating plate is fixed to a base body of the heating element, exclusively in a continuous partial region, the surface of the continuous partial region being smaller than the remaining surface of the heating plate. The invention also relates to a heating element for a filter press, comprising two heating plates which are interconnected by means of spacers, outside the lateral expansion of the base body. The entire base body can be freely displaced between the heating plates, in relation thereto, at least in such a way that a thermal expansion of the heating plates and a different thermal expansion of the base body can take place.
