Anti-abrasion elbow

Abstract

The invention relates to an anti-abrasion elbow. The anti-abrasion elbow comprises a material inlet straight pipe, a box body and a material outlet straight pipe, wherein the material inlet straight pipe, the box body and the material outlet straight pipe are respectively manufactured by adopting double-metal composite anti-abrasion steel plates in a split way, the tail end of a flow-passing surface of the material inlet straight pipe and an impacted surface of the box body are also respectively provided with an anti-abrasion rib plate in a welding way, and the material inlet straight pipe, the box body and the material outlet straight pipe of a split structure are combined into an elbow which is of an integral structure through welding; the anti-abrasion rib plate arranged at the tail end of the flow-passing surface of the material inlet straight pipe is provided with a plurality of crescent-shaped bulges, and the anti-abrasion rib plate arranged on the impacted surface of the box body is of a Chinese character 'jing'-shaped grid structure. According to the anti-abrasion elbow disclosed by the invention, the straight pipes and the box body are manufactured in the split way, a working surface layer is an anti-abrasion surface layer, surfacing of anti-abrasion materials which are resistive in abrasive wear, ablation and the like of abrasive particles is carried out on the working surface, a surfacing surface layer and a structure surface can be flat and uniform, and the material smoothness is sufficient to ensure; the structure is reasonable, the manufacturing technology is simple, the anti-abrasion performance is obtained, the impact resistance is obtained, the anti-abrasion elbow which is subjected to local damage can be conveniently replaced, and the service life of the elbow is effectively prolonged; the anti-abrasion elbow is particularly suitable for being used on factory and mine dedusting equipment of a cement enterprise, a metallurgical enterprise and the like.

Description

Technical field [0001] The invention relates to an elbow, in particular to an adjustable long-life wear-resistant elbow. Background technique [0002] We know that energy industries such as metallurgy and cement are not only the backbone of my country’s industrial economy, but also high energy consumption and high pollution industries. Such basic industries cannot lack dust removal equipment, pipes, and dust removal devices in the production process of technology and environmental protection equipment. Among the various process layouts, the elbow is the most widely used for straight-bending changes. [0003] At present, most of the domestic metal pipe elbows are made of ordinary low-carbon steel plate or low-carbon alloy steel plate. Ordinary low-carbon steel or low-carbon alloy steel has low wear resistance. Working characteristics and traditional manufacturing methods determine its service life. Many domestic steel mills, power plants and other dusty workplaces have serious...

Problems solved by technology

Ordinary low-carbon steel or low-carbon alloy steel has low wear resistance

Working characteristics and traditional manufacturing methods determine its service life. In many domestic steel mills, power plants and other workplaces with a large amount of dust, the phenomenon of running and popping is serious. The service life of the corners or elbows of dust removal or feeding equipment is not good. Ideal, on rare occasions where the elbow wears out in less than a month

The working environment of this kind of pipes and elbows is harsh. Due to the continuous erosion of the air flow, on the one hand, the corners of the pipes are subject to continuous impact;
