Shot blasting machine special for outer wall of cylinder steel pipe

Abstract

The invention relates to a shot blasting machine special for the outer wall of a cylinder steel pipe. The shot blasting machine comprises a shot blasting cleaning chamber, a cylinder steel pipe conveying mechanism, shot blasting devices, a steel shot recycling mechanism, a steel shot lifting device and a shot and sand separation device which is connected to the top of the steel shot lifting device; in the shot blasting process, after shots and sand located at the bottom of the shot blasting cleaning chamber pass through the steel shot lifting device and the shot and sand separation device, steel shots return to all shot blasting devices through a steel shot conveying pipeline; the cylinder steel pipe conveying mechanism is a parallel roller conveying mechanism, and a plurality of shot blasting devices are mounted on the inner wall of the shot blasting cleaning chamber in the circumferential direction. A conventional tapered roller conveying mechanism is changed into the parallel roller conveying mechanism, the problem that abrasion occurs between the roller and the cylinder steel pipe is solved, so that frequent maintenance is not required, the maintenance cost is reduced, at the same time, the plurality of shot blasting devices are mounted on the inner wall of the shot blasting cleaning chamber in the circumferential direction, so that full processing of the cylinder steel pipe is guaranteed, that is the maintenance cost of the roller conveying device is reduced while the shot blasting effect is improved.

Description

technical field [0001] The invention relates to a special shot blasting machine for the outer wall of a steel cylinder steel pipe. Background technique [0002] Existing special shot blasting machine for the outer wall of steel cylinder steel tube comprises a shot blasting room, a steel cylinder steel tube tapered roller conveying mechanism passing through the front and rear ends of the shot blasting room, a steel shot recovery mechanism arranged at the bottom of the shot blasting room, an installation 2 sets of shot blaster assemblies on the top of the shot blasting room, a steel shot lifting device on one side of the shot blasting room, a shot dust separation device connected to the top of the lifting device, and a shot blasting device on the other side of the shot blasting room.

AI Technical Summary

Problems solved by technology

[0003] The disadvantage of the above-mentioned shot blasting machine for the outer wall of steel cylinders and steel pipes is that the conical rollers of the steel cylinders steel pipes conical roller conveying mechanism are installed obliquely at a certain angle, and the workpiece is rotated by friction with the tapered rollers during the shot blasting process. , so on the one hand, it causes damage to the cleaned workpiece surface, and on the other hand, it aggravates the wear of the tapered roller, thus causing disadvantages such as low work efficiency and increased maintenance costs; the 2 mounted on the top of the shot blasting chamber During the shot blasting process of the table shot blasting device assembly, when the tapered roller is worn and the workpiece slips or does not rotate during the rotation process, it will cause incomplete blasting.

[0004] The existing shot blasting cleaning room is directly connected to the dust removal device, which will cause great damage to the dust removal device, often requires maintenance, and the dust removal effect is poor
