Height-adjustable oil gun supporting device

The utility model relates to the technical field of carbon black production, in particular to a height-adjustable oil gun supporting device. In order to solve the problem that when the length of a spray pipe of an oil gun extending into a reaction furnace is small, the spray pipe of the oil gun located outside the reaction furnace is prone to bending deformation due to the gravity of the spray pipe, the height-adjustable oil gun supporting device is provided. Comprising a bracket, a vertically-arranged supporting pipe, channel steel, two supporting bolts, an upper adjusting nut and a lower adjusting nut, the supporting pipe is fixed between the bracket and the center of the top face of the channel steel, bolt holes matched with the supporting bolts are formed in the two ends of the top face of the channel steel, and the two supporting bolts penetrate through the two bolt holes. Each upper adjusting nut is located between the channel steel and the bolt head of the corresponding supporting bolt, and each lower
