The invention discloses a continuous
silicon carbon negative dynamic CVD
sintering furnace, which comprises an installation platform, a spiral feeder, a furnace head cover, a furnace
pipe and a furnace
tail cover, wherein the head end of the furnace
pipe is positioned in the furnace head cover and the
tail end of the furnace
pipe is positioned in the furnace
tail cover, the spiral feeder is joinedwith the furnace head cover, and a discharging port is formed in the furnace tail cover; the part, outside the furnace head cover, of the head end of the furnace pipe is provided with a first sealingflange, a first corrugated pipe is arranged between the first sealing
flange and the furnace head cover, the first sealing
flange is in sealing connection with the first corrugated pipe, and a firstexhaust hood is sleeved on the outer periphery of the connection between the first sealing
flange and the first corrugated pipe; the part, outside the furnace tail cover, of the tail end of the furnace pipe is provided with a second sealing flange, a second corrugated pipe is arranged between the second sealing flange and the furnace tail cover, the second sealing flange is in sealing connection with the second corrugated pipe, and a second exhaust hood is sleeved on the outer periphery of the second sealing flange and the second corrugated pipe. The
sintering furnace adopts the exhaust hood to timely exhaust the gas capable of leaking so as to prevent the danger of explosion caused by the leakage of dangerous gas, and the
sintering furnace has good overall sealing property, is safe and reliable.
