The invention discloses a cement tank with a cooling device. A tank body is in a double-layer arrangement and is divided into an outer wall and an inner wall. A cushion layer is stuffed between the inner wall and the outer wall, and guide pipes are arranged on the external side of the inner wall. A cooling water inlet and a cooling water outlet are respectively arranged at two ends of the guide pipes, and a cement temperature measurement port is arranged at a cement outlet position. A vibrorammer is mounted at the lower end of the tank body, the cushion layer is an asbestos cushion layer, the guide pipes are DN 20 seamless steel pipes, and the guide pipes are spirally wound on the external side of the inner wall. By using cool water to cool cement directly and with a reasonable structure, the cement tank with the cooling device solves the problems of complex operation and high cost, and can be directly transformed on the basis of an original cement tank, and accordingly cost of an enterprise is saved.
