The invention discloses a stirring tank which comprises a tank body (1), and further comprises an elastic support (2) and a vibrating device (3), wherein the tank body (1) is fixed on the elastic support (2), and the vibrating device (3) drives the tank body (1) to vibrate on the elastic support (2). The stirring tank provided by the invention is provided with the vibrating device, so that the tank body can vibrate. While reacted, substances in the stirring tank can be stirred and vibrated as well, and therefore, the stirring tank provided by invention can effectively prevent phenomena of stirring dead zones and wall sticking during the reaction, so the reacting substances can be fully stirred, thereby improving reaction efficiency and effect.
