Modified gun pipeline spray repair device

The utility model belongs to the improvement, especially a modified gun pipeline spray repair device of steel mill converter refractory material gun structure, include setting up the spray repair pipe on the discharge gate of storage tank lower part, the spray repair pipe is being connected to the pneumatic control pipe network, and it is managed in the decurrent spray repair of standing upright, and the port is closed through sealing the flange board down, setting up the side and exporting on the pipe wall of spray repair pipe, and side spray repair pipe and the spray repair pipe connected on the side exports are perpendicular, and the pneumatic tube is connected with the spray repair pipe, and the spout of pneumatic tube and the import that the side spray repair was managed are corresponding. Its is rational in infrastructure, and it is reliable to operate steadily, can reduce the erodeing of spray repair pipe, and the life of extension pipeline improves the gun and to the spray repair effect of dip pipe, reduces the pollution to the environment.
