SEALING GATE FOR FURNACE FOR CONTINUOUS HEAT TREATMENT OF FIBER CARBON MATERIAL Russian patent published in 2017 - IPC D01F9/133 F27B13/06 F27D7/06 

FIELD: machine engineering.

SUBSTANCE: sealing gate for the furnace for continuous heat treatment of the carbon fiber material comprises a body 1 with a longitudinal through passage 2 for the material to be treated 3. The body 1 is made in the form of two aligned sections - a receiving section 4 and an outlet section 5. On one side, the body 1 is equipped with a flange 6 for fastening to the furnace working chamber and flaps 7 at the channel 2 outlet. Above and below the channel 2 in the receiving section 4 heat-insulated heated chambers 8 are placed, the lower one has a cavity 9 with nozzles 10 for process gas heating. In the side wall of the receiving section 4 channel 2, a window 11 is provided for communicating via a heated branch pipe 12 with a burner 13 for exhaust gases combustion.
