Surface treatment shot blasting device for steel structure

Abstract

The invention relates to a surface treatment shot blasting device for a steel structure. The surface treatment shot blasting device comprises a conveying platform, a shot blasting grinding box and a blowing cleaning box. Roll shafts are evenly distributed on the conveying platform. The conveying platform penetrates through the lower portion of the shot blasting grinding box and the lower portion of the blowing cleaning box transversely in sequence. Steel shot nozzles facing the conveying platform are evenly mounted on the top and the sidewall of the shot blasting grinding box. A blowing pipe which is arranged vertically downwards is arranged at the top end of the interior of the blowing cleaning box. The bottom of the shot blasting grinding box is provided with a steel shot collection box. The lower end of the blowing cleaning box is provided with a collection hopper which communicates with the steel shot collection box. The surface treatment shot blasting device for the steel structure achieves automatic recycling of steel grits and steel shots, has the steel structure surface cleaning function and greatly improves the production efficiency.

Description

technical field [0001] The invention relates to the field of steel structure production equipment, in particular to a surface treatment shot blasting device for steel structures. Background technique [0002] Shot blasting machine is a processing technology that impacts steel sand and steel shots on the surface of material objects by high-speed throwing of steel sand and steel shots through a shot blasting machine. It is faster and more efficient than other surface treatment techniques and can be used for part retention or stamping after the casting process. Shot blasting equipment is firstly used to remove sand and scale on the surface of cast steel and iron castings in the foundry industry [0003] Almost all steel structures are steel castings, gray castings, malleable steel parts, ductile iron parts, etc., and these steel structures must be shot blasted. This is not only to remove scale and sticky sand on the surface of the casting, but also an indispensable preparatio...

AI Technical Summary

Problems solved by technology

[0004] In the existing shot blasting equipment, the steel grit and steel shot fall into the equipment after impacting the surface of the steel structure, and it is often necessary to manually shovel the dropped steel grit and steel shot to the upper end of the equipment to realize the repeated use of the steel grit and steel shot , time-consuming and labor-intensive, and the working environment of the workers is bad, so they cannot work for a long time

[0005] In addition, there will be powder left on the surface of the steel structure impacted by the steel grit and steel shot or the steel grit and steel shot will be directly stuck to the surface of the steel structure. Afterwards, the surface needs to be cleaned manually with a brush, resulting in a large workload and low production efficiency.
