Device for filtering a plastic melt

A device for filtering a plastic melt,

• comprising a housing which has at least one inlet channel and at least one outlet channel for the plastic melt,
• wherein the at least one inlet channel is separated from the at least one outlet channel by at least one cavity for accommodating at least one filter pin which is axially and/or radially movable therein,
• wherein the at least one filter pin has a filter section to which at least one filtering means is detachably fastened so that the filter section of the at least one filter pin and the at least one filtering means define a filtrate cavity,
• wherein, in a working position of the filter pin, the plastic melt can pass from the at least one inlet channel through the filtering means to the filtrate cavity and the filtrate cavity is in fluid connection with the at least one outlet channel, and
• wherein, in a filter change position of the filter pin, the filtering means is freely accessible for replacing the filtering means, and at least one drainage channel is formed in the filter pin, wherein, in a start-up position of the filter pin, one end of the at least one drainage channel is in fluid connection with the at least one inlet channel in order to receive the plastic melt that is fed through the at least one inlet channel and to output the plastic melt at another end of the at least one drainage channel;
• wherein the at least one drainage channel runs within at least one web in an axial direction through the filtrate cavity of the filter pin.
