Vacuum cleaning structure for electrode furnace

摘要

An electrode for a resistance analytical furnace has a crucible-engaging surface and an end spaced from the crucible-engaging surface having a plurality of grooves formed therein. A manifold mounted on the end of the electrode defines a dust recovery plenum and includes an outlet communicating with the plenum for coupling to a vacuum source to remove debris from the electrode. The improved electrode and electrode cleaning manifold positioned on the electrode provides a turbulent airflow for removal of dust and debris from an analytical furnace.

1. A dust recovery system for an electrode of an analytical resistance furnace comprising:
an analytical furnace including a chamber for housing an upper electrode; an upper electrode positioned in said chamber and having a crucible-receiving furnace with a contact for engaging one end of a resistive crucible, said upper electrode having an end spaced from said contact with a plurality of grooves formed therein; a lower electrode for supporting an opposite end of a crucible within said furnace of said upper electrode; and a manifold fitted over said end of said upper electrode to define a dust recovery plenum surrounding said plurality of grooves in said upper electrode, said dust recovery plenum including an outlet for coupling to a vacuum source to remove debris from said electrode.
