Description

Pipeline elbow with wear resistance and grinding leakage warning function Technical Field The utility model belongs to the technical field of pipeline connectors, and particularly relates to a wear-resistant pipe connector And a pipeline elbow with a grinding leakage alarming function. Background During the production of pellets, a large amount of dust is produced. After the dust is recovered in the dust removing process, the dust is sent to a proportioning bin through a bin pump and an ash conveying pipeline to participate in proportioning again. The main component of the dust is iron ore concentrate, the particles are harder, and in the process of being driven to advance by compressed air, the pipeline can be quickly flushed, especially the elbow part of the pipeline connecting piece is more worn and frequently replaced, and secondary pollution and site environment deterioration can be caused. In order to prolong the service life of the elbow, the existing pipeline wear-resistant elbow is mainly realized by thickening the inner wall of the elbow, so that the weight of a single wear-resistant elbow is increased, and the installation is inconvenient. Meanwhile, the service life of the elbow is limited, approximately 2 months, the problem of elbow abrasion is not technically solved, repair welding is also often needed, and the use effect is not ideal. Meanwhile, the elbow cannot be found in time after grinding leakage, so that secondary dust emission on site is caused, and the clean site environment is damaged. Disclosure of utility model The utility model aims to provide a pipeline elbow with wear resistance and grinding leakage warning functions. The pipeline elbow can reduce the wear degree of the elbow, has long service life, saves spare parts and eliminates pollution sources. The utility model relates to a pipeline elbow with wear resistance and grinding leakage alarming functions, which comprises a metal pipeline elbow and is characterized in that a layer of polymer composite wear-resistant layer is coated on the inner wall of the metal pipeline elbow, an arc middle buckle plate is arranged on the outer wall of the lower part of the metal pipeline elbow, the arc middle buckle plate consists of two vertical plate supporting plates, an arc vibration sensing plate and two angle steels, the lower ends of the two vertical plate supporting plates are welded with the outer wall of the metal pipeline elbow, the upper ends of the two vertical plate supporting plates are lapped with the arc vibration sensing plate, the angle steels are arranged on the inner sides of the arc vibration sensing plates, one ends of the angle steels are welded with the inner sides of the two vertical plate supporting plates, the other ends of the angle steels are fixedly connected with the arc vibration sensing plate through bolts, two vibration sensors are arranged on the outer sides of the vibration sensing plate at intervals, and the two vibration sensors are electrically connected with a PLC. Preferably, the polymer composite wear-resistant layer is formed by spraying a 2mm thick rubidium-iron-boron material, and then spraying a 3mm thick polymer ceramic wear-resistant material on the surface of the rubidium-iron-boron material. The utility model has the advantages that: Compared with the prior art, the utility model can reduce elbow abrasion, improve production efficiency and reduce spare part loss, and meanwhile, the post can timely find out on-site ash leakage and arrange maintenance personnel to timely treat.
