Abstract

The invention discloses an automatic shot blasting device for a large steel tube or steel beam. The automatic shot blasting device comprises a shot blasting chamber, a workpiece pushing car system, a circulating sand blasting system and a purification system, wherein the shot blasting chamber comprises a sand blasting chamber which is provided with a channel allowing a workpiece to pass through; the workpiece pushing car system is arranged along the workpiece channel of the sand blasting chamber; the circulating sand blasting system comprises an auger conveying component, a steel shot hoister and a sand-sliding pipe; the purification system comprises an air pipe, a fan, a cyclone separator and a dust removing chamber. The inner space of the sand blasting chamber of the automatic shot blasting device is large and particularly suitable for surface treatment for the large steel tube or steel beam. The automatic shot blasting device can prevent dust from polluting the environment, greatly reduce steel shot loss and relieve labor intensity and has the advantages of being small in pollution, low in cost and capable of improving production safety. The workpiece pushing car system drives the workpiece to automatically rotate, uniform effects on all the surfaces of the workpiece are guaranteed, nonuniformity of roughness values is reduced, and the product quality is guaranteed.

Description

technical field

[0001] The invention relates to the field of steel processing equipment, in particular to an automatic shot blasting device for large steel pipe steel girders. Background technique

[0002] At present, shot blasting machines are commonly used to clean and derust the surface of large steel pipes, steel beams and other workpieces. The working principle of the shot blasting machine is to drop steel sand and steel shots at high speed and impact on the surface of the workpiece through the shot blaster to remove pollutants, burrs, rust, etc. on the surface of the workpiece. Compared with other surface treatment technologies, it can strengthen the surface performance of the workpiece , which has the advantage of being faster and more efficient.

[0003] The original conventional steel pipe and steel beam shot blasting device usually has less steel structure and less internal space, and the shot blasting box is easily damaged. It is not suitable for processing large...
