Anti-rust paint spraying device for long-period smooth operation of large blast furnace and using method of anti-rust paint spraying device

Abstract

The invention discloses an anti-rust paint spraying device for long-period smooth operation of a large blast furnace and a using method of the anti-rust paint spraying device. The anti-rust paint spraying device for long-period smooth operation of the large blast furnace comprises a carriage, a paint storage mechanism is arranged at one end of the top of the carriage, and a first connecting hose is arranged at the bottom of the paint storage mechanism. The technical scheme has the beneficial effects that the paint storage mechanism is convenient for better storing paint and preventing the paint from caking, a position adjusting mechanism is convenient for better driving a spraying mechanism to move and adjust the height and the angle of the spraying mechanism, so that the spraying mechanism is better matched with external pipelines for spraying, the spraying mechanism is convenient for better spraying the outer sides of the pipelines, meanwhile, the overall size of the spraying mechanism can be changed by increasing or decreasing connecting short pipes, so that the external pipelines with different sizes can be better sprayed, in addition, the outer side of the high-altitude pipeline is directly sprayed on the ground, so that the operation safety of workers is improved, and the risk of high-altitude operation is avoided.

Description

technical field [0001] The invention relates to the technical field of paint spraying devices, in particular to a long-period antegrade rust-proof paint spraying device for large blast furnaces and a method for using the same. Background technique [0002] The blast furnace is made of steel plate as the furnace shell, and the shell is lined with refractory bricks. From top to bottom, the blast furnace body is divided into five parts: the furnace throat, the furnace body, the furnace waist, the furnace bosh, and the hearth. Due to the good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor production efficiency, and low energy consumption, the iron produced by this method accounts for the vast majority of the world's total iron production. Pipes of various heights and sizes are installed around the blast furnace. During long-term operation, the pipes are prone to rust due to exposure, which affects the overall o...

Problems solved by technology

Pipes of various heights and sizes are installed around the blast furnace. During long-term operation, the pipes are prone to rust due to exposure, which affects the overall operation quality of the blast furnace system. Therefore, it is necessary to jack up and maintain the outside of the pipes for anti-rust painting. The paint spraying device generally needs to be aligned manually. When the pipeline is high, it is difficult to spray, requiring the staff to work at high altitudes, and the risk is high
