STIRRER FOR DIGESTION TANK

摘要

PURPOSE:To prevent surely clogging in a cylindrical body for draft and to improve a stirring effect by blowing fluid in a digestion tank from the outside of said cylindrical body and blowing diagonally upward the fluid. CONSTITUTION:An annular header 4 is provided to the circumference of the cylindrical draft 3 for draft and a gas blowing pipe 5 is communicated with the header 4 to which a gas is supplied from an outside supply source A. A nozzle 6 is provided between the body 3 and the header 4. The air A passing through the pipe 5 is blow off via the header 4 diagonally upward in approximately the tangential direction from each blow-off nozzle 6. The clogging of the cylindrical body is thus surely prevented and particularly the swirling upward flow is induced, by which the stirring effect is improved.
