CLAIM:
1. A molten sulfur lift for providing a constant molten sulfur head with a varying inlet head comprising a vertical outer housing having a molten sulfur inlet, a cylindrical, vertical inner housing having an open bottom and an open top spaced above the floor of said outer housing and forming a vertical annular passageway between the walls of said inner and outer housings, a molten sulfur discharge pipe in fluid communication with the upper portion of said inner housing below the open top thereof passing outwardly and downwardly from said inner housing through said outer housing for removing molten sulfur from said lift, a rotatable screw confined within said inner housing extending substantially from the open bottom of said inner housing to said molten sulfur discharge pipe for lifting said molten sulfur from the lower volume enclosed by said outer housing through said open top of said inner housing and into said annular passageway, flapper valve means positioned within said molten sulfur discharge pipe for closing said discharge pipe and interrupting the flow of molten sulfur therethrough, and conduit means in fluid communication between the lower volume enclosed by said outer housing and said discharge pipe at a point downstream from said flapper valve means for conveying molten sulfur from said lower volume to said discharge pipe.





2. The molten sulfur lift of claim 1 further comprising pressurizing means for pressurizing the internal volume of the sulfur lift and forcing molten sulfur through said conduit to said discharge pipe.





3. The molten sulfur lift of claim 2 wherein said pressurizing means comprises an air blower for passing air into said molten sulfur lift upon closure of said flapper valve.
