Cooling flange joint

The utility model relates to a cooling flange joint which comprises a first flange plate and a second flange plate, the side wall of the first flange plate and the side wall of the second flange plate are both fixedly connected with flange connecting pipes, the peripheries of the flange connecting pipes are sleeved and connected with cooling cylinders, the peripheries of the cooling cylinders are fixedly connected with damping buffer seats, and the number of the damping buffer seats is four. The first flange plate and the second flange plate are fixedly connected with damping buffer seats, the damping buffer seats are annularly arranged and distributed, the tail ends of the damping buffer seats are fixedly connected with an anti-collision buffer plate, and the anti-collision buffer plate is of an arc-shaped structure. The external acting force can be buffered by arranging the damping buffering base and the anti-collision buffering plate, the situation that the external acting force impacts on the surface of t
