[0002] Steel shot blasting treatment is a commonly used surface treatment process. By mechanical method, the shot is projected to the surface of steel at a high speed and a certain angle, so that the shot impacts the surface of steel at a high speed, which can effectively remove the scale, rust, dirt and other impurities on the surface of steel, so that the surface of steel presents uniform and consistent metal luster, and the surface quality of steel is improved.

The inside of the cleaning box is provided with a cleaning device. The cleaning device comprises two groups of symmetrical lifting units and cleaning units. The top of the cleaning box is provided with a rust removal device, which comprises a rust removal unit and a recovery unit. The shot blasting machine with rust removal and recovery function for steel structure surface treatment can treat the rust on the steel plate through the shot blasting machine. The ejected steel shot and rust roll down to the inside of the reflux tank. The rust and steel shot are separated by a filter plate. After the shot blasting machine treats the rust on the surface of the steel, if there is rust remaining on the surface of the steel, the brush is driven by the lifting cylinder to move down to contact the surface of the steel. The brush is rotated by the friction of the steel conveying, so as to brush off the rust remaining on the surface of the steel and complete the cleaning of the surface of the steel.
