Abstract:
A horizontal shot blasting machine system and a treatment method. The shot blasting machine system comprises a shot blasting chamber and a shot blasting device. The axis of the shot blasting chamber is arranged in a horizontal direction. The shot blasting device comprises an inner shot blasting device and an outer shot blasting device. The inner shot blasting device is communicated with a high-pressure pneumatic sand conveying device. Sand shots are conveyed to the inner shot blasting device through the high-pressure pneumatic sand conveying device after being accelerated for the first time by means of high-pressure airflow, and then the sand shots are thrown out through the inner shot blasting device after being accelerated again. After a steel pipe to be treated enters the shot blasting chamber, an inner wall of the steel pipe undergoes shot blasting treatment through the inner shot blasting device. The outer shot blasting device is located on the wall of the shot blasting chamber, a shot blasting opening faces an outer wall of the steel pipe, and the outer wall of the steel pipe undergoes shot blasting treatment. Shot blasting treatment on the inner and outer walls of the steel pipe is achieved in an advancing process of the steel pipe. The shot blasting machine system is high in sand supplying capacity and stable in flow, has good automatic sand shot removing and recovering effects, and has a simple structure.
