Device for lowering blowing noise of steel tube dust blowing and sucking device

Abstract

The invention relates to a device for lowering blowing noise of a steel tube dust blowing and sucking device. The device comprises two pipeline connectors with variable diameters, 2n pipelines, n checking valves and n mufflers, wherein the n is greater than 2. One of the pipeline connectors with the variable diameters is connected with a main blowing pipeline of an air storage tank. One end of each of the n pipelines is connected with one pipeline connector with the variable diameters, and the other end of each of the n pipelines is connected with one checking valve. Each checking valve is also connected with one muffler. One end of each of the other n pipelines is connected with one muffler, and the other end of each of the other n pipelines is connected with the other pipeline connector with the variable diameters. The other pipeline connector with the variable diameters is connected with a blowing nozzle. The sectional area of any one of the 2n pipelines is smaller than the sectional area of the main blowing pipeline. Through the technical scheme of the device for lowering the blowing noise of the steel tube dust blowing and sucking device, the blowing noise can be effectively lowered, the purposes of energy conservation and remission reduction can be achieved, and the device is quite suitable for being used practically.

Description

technical field [0001] The invention relates to the hot-rolling technology of steel pipes, in particular to a device for reducing blowing noise of a steel pipe ash blowing and suction device. Background technique [0002] At present, in the steel pipe hot rolling production line, the steel pipe soot blowing device located in the finishing area usually uses a one-way air duct system to remove the cut-to-length sawdust remaining in the inner hole of the steel pipe, and the oxidation on the surface of the steel pipe during hot rolling and cooling. Iron sheet, and the oxidized iron sheet peeled off on the inner hole of the steel pipe after straightening on the steel pipe heat treatment line, so as to avoid misjudgment of the internal defects of the metal structure caused by these non-steel pipe body metal substances during the steel pipe flaw detection, thereby avoiding the growth of the steel pipe The impact of the rate and the existence of hidden dangers of steel pipes.
