Horizontal flame gunning machine

Abstract

The invention provides a horizontal flame gun. The structure of the gun comprises a double-layer sand blasting casting connected with a coaxial swirl synthesizer; the upper part of the coaxial swirl synthesizer is connected with a transfer hose, the tail end is connected with a sand blasting hose and a rotation device is provided internally. A gear driven by rotating is connected with rotary cycloidal needle wheel decelerator; the upper part of the rotation driving device is fixedly connected with a piston rod of a vertical swinging hydraulic cylinder; the lower end of a support frame of the coaxial swirl synthesizer is connected with a horizontal swinging hydraulic cylinder which is fixed on a frame plate; the lower part of the frame is provided with a passive wheel assembly and an active wheel assembly; a fire plate is provided between the double-layer sand blasting casting and the coaxial swirl synthesizer. The invention has the advantages that: the flame gun does not damage the original refractory lining; the adhesive rate of gunning refractory is high; the sintering is instant; the invention and the original refractory lining form ceramic bond to develop into novel refractory lining surface layer. The invention can be widely applied in hot gunning and gunning under normal temperature and isolate heat radiation from causing damage to equipment and human body.

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.
