Automatic control method for impeller blasting

Abstract

The invention discloses an automatic control method for impeller blasting. Firstly, rolled steel on which rust removal will be conducted is placed on a conveying system, when the rolled steel moves to a shot blasting chamber, a photoelectric sensor, right opposite to the conveying system, of the shot blasting chamber inducts the rolled steel, and a controller controls an impeller head in the shot blasting chamber to be started to conduct shot blasting treatment on the rolled steel; and after the photoelectric sensor inducts that the rolled steel is moved out of the shot blasting chamber, the controller controls the impeller head to be stopped, meanwhile, an electric control magnet in the shot blasting chamber is controlled to be opened, and shot blasting particles are attracted and recycled. According to the automatic control method, the photoelectric sensor is used for inducting whether the rolled steel enters the shot blasting chamber or not, after the rolled steel enters the shot blasting chamber, the impeller head is started, it is guaranteed that the impeller head is accurately aligned with the rolled steel to carry out shot blasting treatment on the rolled steel, casting of the shot blasting particles is avoided, and energy consumption is reduced. The electric control magnet is arranged, and after shot blasting treatment is ended, the shot blasting particles are recycled, the difficulty of manual recycling and cleaning is lowered, and the time of manual recycling and cleaning is shortened.

Description

technical field [0001] The invention relates to the field of shot blasting and rust removal of steel structure materials, in particular to an automatic control method for shot blasting and rust removal. Background technique [0002] In the process of steel structure manufacturing, shot blasting and derusting work is one of the important processes, and all components should be derusted by shot blasting. In the existing shot blasting equipment, after the steel structure material enters the conveying system, the shot blaster starts to perform shot blasting treatment, but at the initial stage, because the steel structure has not entered the shot blasting room, the shot blasting particles are thrown out of the shot blasting room, causing Difficulty cleaning shot blast particles. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic control method for shot blasting and rust removal, which automatically controls...
