Horizontal flame gun

Abstract

The invention provides a horizontal flame gunning machine, the machine structure includes a double-layer sandblasting casing, a coaxial rotary combiner is connected with the casing, and an oxygen delivery hose is connected to the upper part of the coaxial rotary combiner. The tail end is connected with a sandblasting hose, and there is a rotating device inside, which is connected with the rotary cycloid reducer through the rotating driving gear; the piston rod of the vertical swing hydraulic cylinder is fixedly connected to the upper part of the rotating driving device; The lower end of the support frame of the coaxial rotary combiner is connected with a horizontal swing hydraulic cylinder fixed on the frame plate; the lower part of the frame is provided with a passive wheel set and an active wheel set; between the double-layer sandblasting casing and the coaxial rotary combiner There is a fire damper in the room. The effect of the present invention is that the flame gunning machine does not damage the original refractory inner lining, the gunning material has a high adhesion rate, instant sintering, forms a ceramic bond with the original refractory inner lining, and develops into a new refractory inner lining surface layer. It can be widely used for thermal gunning, and can also be used for gunning at room temperature to prevent damage to equipment and human body caused by thermal radiation.

Description

technical field [0001] The invention belongs to equipment for repairing the refractory inner lining of a metallurgical industrial furnace, in particular to a horizontal flame gunning machine. Background technique [0002] At present, single-flow gunning equipment is used for hot-repairing the refractory lining of horizontal industrial furnaces. Its working principle is as follows: the repairing material conveyed by pneumatic force is transported into the sandblasting steel pipe by the sandblasting hose, and humidified at the rear of the sandblasting steel pipe, the steel pipe is inserted into the furnace through the furnace mouth, and the sandblasting steel pipe is swung left and right, up and down, so that after humidification The repairing material conveyed by pneumatic force is sprayed onto the lining surface of the industrial furnace that needs to be repaired, so as to achieve the purpose of repairing the furnace. This method has a low degree of mechanization, and the o...

Problems solved by technology

This method has a low degree of mechanization, and the operator is working in a strong heat radiation environment, and the labor intensity is high.

The humidified repair material is easy to adhere to the inner wall of the steel pipe, which reduces the inner diameter of the steel pipe and causes the gunning material to be blocked. The hot refractory lining is easy to cause rapid cooling and cracking, which will cause the original refractory lining surface to fall off and be damaged.
